In the practical application process, the two ends of the supporting member 200 are fixedly connected with the pot body, and the cover body 100 is opened or locked relative to the pot body by operating the cover body 100 to rotate relative to the pot body and the supporting member 200.
As shown in fig. 2 and 4, the center of the cover 100 is provided with a center post 150, and the cover 100 is further provided with a connection post 130 in a region offset from the center post 150. The center of the supporting member 200 is provided with a clamping groove 250, and correspondingly, a connecting hole 230 matched with the connecting post 130 is formed in the area of the supporting member 200 deviating from the clamping groove 250, as shown in fig. 1, the connecting hole 230 is in a section of arc shape, so that the connecting post 130 can relatively rotate and relatively slide in the connecting hole 230. The supporting member 200 is rotatably sleeved on the central column 150 and the connecting column 130 through the clamping groove 250 and the connecting hole 230, respectively, specifically, when the rotating cover body 100 is operated, the supporting member 200 can rotate relative to the central column 150 through the clamping groove 250, and further rotate relative to the center of the cover body 100, and meanwhile, the connecting column 130 on the cover body 100 also rotates relative to the center of the supporting member 200, and the connecting hole 230 is arc-shaped, so that the connecting column 130 can slide relatively in the connecting hole 230. In addition, the supporting member 200 can also rotate with respect to the connection post 130 through the connection hole 230, thereby eccentrically rotating with respect to the cover 100.
Further, as shown in fig. 2 and 4, the pot cover 300 further includes a rotation operation member 260, the rotation operation member 260 includes a rotation post 265, the rotation post 265 is rotatably installed in the clamping groove 250, and the clamping groove 250 and the rotation post 265 are both sleeved on the center post 150, so that the center post 150 is also located in the rotation post 265. As shown in fig. 6, a notch 261 is formed at the lower end of the side wall of the rotating column 265, specifically, an annular fixing wall 268 is formed at the lower end of the rotating column 265, and the notch 261 is disposed on the annular fixing wall 268, which means that the notch 261 is in a corresponding relationship with the annular fixing wall 268 and is opposite to the annular fixing wall 268.
As shown in fig. 2, 7 and 8, the rotating operation member 260 is rotated to rotate the rotating post 265 relative to the clamping groove 250, and the rotating post 265 can rotate until the annular fixing wall 268 is connected with the inner wall of the clamping groove 250 to form a closed ring, that is, the notch 261 is blocked by the inner wall of the clamping groove 250, so that the central post 150 can be locked by the closed ring, at this time, the supporting member 200 can only rotate relative to the central post 150 (that is, rotate relative to the center of the cover 100) and cannot be separated from the central post 150, so that the supporting member 200 cannot be detached from the cover 100, that is, the supporting member 200 is locked with the cover 100.
In addition, as shown in fig. 4 and 9, by rotating the rotating operation member 260, the rotating column 265 rotates relative to the clamping groove 250, and the notch 261 on the rotating column 265 rotates to a designated position, at this time, the notch 261 is no longer blocked by the inner wall of the clamping groove 250, the center column 150 is no longer locked by the closed ring, when the supporting member 200 is rotated, the supporting member 200 does not rotate relative to the center column 150, but rotates eccentrically relative to the connecting column 130 at the eccentric position on the cover 100, the center column 150 also rotates relative to the connecting column 130 and is offset relative to the clamping groove 250, and the center column 150 can move outside the notch 261 and be separated from the clamping groove 250, as shown in fig. 10. At this time, the support 200 is in an unlocked state with the cover 100, and the support 200 can be detached from the cover 100 and separated from the cover 100. It can be seen that the support 200 can be unlocked from the cover 100 by manipulating the rotating posts 265 to the corresponding positions, thereby facilitating the disassembly of the support 200 and cleaning.
According to one embodiment, the support 200 has a slot 250 formed therein. The cross section of the clamping groove 250 is in a transverse gourd shape, and comprises a containing groove part with a larger radius and a limiting groove part with a smaller radius, the center column 150 is located in the limiting groove part, and the rotating column 265 is installed in the containing groove part.
Specifically, when the operation rotation post 265 rotates, the notch 261 can rotate along with the rotation post 265 to a position opposite to the above-mentioned limit groove, that is, a position where the annular fixing wall 268 overlaps the limit groove, so that the closed-loop locking center post 150 cannot be formed, at this time, the support member 200 is eccentrically rotated relative to the connection post 130 by rotating the cover 100, and the center post 150 can relatively move out of the notch 261 to be separated from the locking groove 250. In addition, the notch 261 can rotate along with the rotating post 265 to a position overlapping the limit groove, that is, a position where the annular fixing wall 268 is opposite to the limit groove, and the inner wall of the annular fixing wall 268 of the rotating post 265 and the inner wall of the limit groove are connected together to form a closed loop, through which the central post 150 can be locked.
According to yet another embodiment, as shown in fig. 2, 4 and 5, a cavity is formed in the center of the support 200, and an axle seat 220 is fixedly installed in the cavity, and the axle seat 220 and the support 200 are of a split type structure. Referring to the schematic structural diagram of the axle seat 220 shown in fig. 5, the axle seat 220 is provided with a clamping groove 250 and a limiting groove 251, and the axle seat 220 is further provided with a notch 252 communicating with both the clamping groove 250 and the limiting groove 251. As shown in fig. 6 to 9, the rotating post 265 is located in the clamping groove 250, the rotating operation member 260 is rotated to enable the rotating post 265 to rotate relative to the clamping groove 250, and the notch 261 on the side wall of the rotating post 265 can rotate along with the rotating post 265 to align with or stagger with the notch 252. When the notch 261 rotates to be staggered from the notch 252, the closed-loop locking center column 150 can be formed, as shown in fig. 7 and 8, and when the notch 261 rotates to be aligned with the notch 252, the center column 150 is not locked, so that the center column 150 can relatively move outside the notch 261, as shown in fig. 9 and 10.
Specifically, the shaft seat 220 is a hollow cylindrical structure with an opening at one end, and includes an opposite opening end at an upper end and a sealing end at a lower end, the sealing end extends upward inwards to form a fixed inner cylinder 258, and the fixed inner cylinder 258 is provided with a middle through hole penetrating through the sealing end of the shaft seat 220, and the middle through hole is a limiting groove 251. The shape of the limit groove 251 is matched with the shape of the center column 150, so that the center column 150 is clamped in the limit groove 251. As shown in fig. 5, the clamping groove 250 is a space between the inner wall of the shaft seat 220 and the outer wall of the fixed inner cylinder 258, and the opening 252 is formed at the lower end of the side wall of the shaft seat 220 and penetrates the sealing end of the shaft seat 220 and the wall of the fixed inner cylinder 258.
As shown in fig. 2,4 and 5, the height of the fixed inner cylinder 258 is smaller than the height of the shaft seat 220, and the fixed inner cylinder 258 is coaxially disposed with the inner wall of the shaft seat 220. An annular stationary wall 268 is rotatably mounted between the outer wall of the stationary inner barrel 258 and the inner wall of the shaft mount 220. As shown in fig. 5, the notch 252 is formed at the junction between the side wall and the bottom wall of the shaft seat 220, and the cross section of the notch 252 is L-shaped, that is, the lower end of the side wall and the bottom wall of the shaft seat 220 have a part of structures penetrating the clamping groove 250. The fixed inner cylinder 258 is formed by extending upwards from the joint between the bottom wall of the shaft seat 220 and the notch 252, so that the fixed inner cylinder 258 is connected with the bottom of the notch 252.
Further, referring to fig. 2,7 and 8, when the rotation operation member 260 is rotated to rotate the annular fixing wall 268 on the rotation column 265 to a position opposite to the limit groove 251 of the fixing inner cylinder 258, the notch 261 is rotated to be offset from the notch 252, and the annular fixing wall 268 on the rotation column 265 is connected with the inner wall of the fixing inner cylinder 258 to form a closed loop in the relative position of the rotation column 265 and the clamping groove 250 in fig. 2, thereby locking the center column 150, and at this time, the supporting member 200 can only rotate relative to the center column 150 and the center of the cover 100 and cannot be separated from the center column 150, and at this time, the supporting member 200 and the cover 100 are locked and cannot be separated from each other. As shown in fig. 4, 9 and 10, by rotating the rotary operation member 260, the annular fixing wall 268 on the rotary column 265 is rotated 180 ° further, and then the annular fixing wall 268 is rotated to fit around the outer wall of the fixing inner tube 258, and the notch 261 is rotated to align with the notch 252, so as to take into account the relative positions of the rotary column 265 and the locking groove 250 in fig. 4. At this time, when the cover 100 is rotated, the support member 200 rotates eccentrically around the connecting post 130 relative to the cover 100, and the central post 150 also rotates relative to the connecting post 130 and moves out of the notch 261 relative to the slot 250, so that the support member 200 can be detached from the cover 100 and separated from the cover 100, i.e. the support member 200 is in an unlocked state with respect to the cover 100.
Alternatively, as shown in fig. 7 and 9, the cross section of the center column 150 is in an "i" shape, which includes a center column 155, and further includes a first stopper 151 and a second stopper 152 fixed to the upper and lower ends of the center column 155, respectively, and stepped surfaces are formed between the center column 155 and the first and second stoppers 151 and 152, respectively. The central column 155 may be clamped in the limiting groove 251 and abuts against the inner wall of the fixed inner cylinder 258.
Specifically, as shown in fig. 2 and 4, the lower end surface of the first stopper 151 abuts against the upper end edge of the fixed inner tube 258, and the annular fixing wall 268 at the lower end of the rotating post 265 rotatably abuts against the side end surface of the first stopper 151, that is, when the rotating post 265 rotates, the annular fixing wall 268 at the lower end of the rotating post 265 can rotate with the rotating post 265 relative to the first stopper 151 and abut against different portions of the side end surface of the first stopper 151. In addition, as shown in fig. 7 and 9, the bottom of the clamping groove 250 is further provided with an arc-shaped baffle 255, and the arc-shaped baffle 255 is the bottom wall of the sealed end of the shaft seat 220. The central column 155 is clamped in the limiting groove 251 of the clamping groove, and the arc-shaped baffle 255 is blocked on the side wall of the central column 155 and located at the step surface of the second stop block 152, that is, the arc-shaped baffle 255 is blocked on the side wall of the central column 155 and blocked on the upper end edge of the second stop block 152.
In addition, in the embodiment according to the present invention, as shown in fig. 1 to 4, two stopper posts 110 are symmetrically provided on the cover body 100 with respect to the center of the cover body 100, and the connection post 130 is disposed in the region between the center post 150 and the stopper posts 110. Correspondingly, two arc-shaped grooves matched with the limit posts 110 are symmetrically arranged on the supporting piece 200 relative to the center of the supporting piece 200, and each arc-shaped groove comprises a first section of guide groove 210 and a second section of offset groove 215 smoothly connected with the first section of guide groove 210.
In the state that the supporting member 200 is locked to the cover 100 as shown in fig. 1, when the supporting member 200 rotates relative to the center of the cover 100, the limiting posts 110 on the cover 100 are driven to slide relative to the guide slots 210, and the sliding tracks of the two limiting posts 110 in the corresponding guide slots 210 are symmetrical relative to the center of the supporting member 200, as shown in fig. 3, when the rotating operation member 260 rotates to make the center post 150 not locked by the closed loop, the supporting member 200 rotates eccentrically relative to the connecting post 130 of the cover 100, and drives the two limiting posts 110 to rotate relative to the connecting post 130 and deflect in the deflection slots 215, it should be understood that the deflection tracks and distances of the two limiting posts 110 in the corresponding deflection slots 215 are different due to the eccentric rotation, and preferably, the symmetrical centers of the two deflection slots 215 are deviated from the center post 150, for example, the symmetrical centers of the two deflection slots 215 are located at the positions of the connecting post 130, so as to be more beneficial to the deflection of the limiting posts 110 in the deflection slots 215. Here, the guide grooves 210 and the offset grooves 215 cooperate with the stopper posts 110 to assist in guiding the rotation and eccentric rotation of the support member 200 with respect to the center of the cover body 100, thereby assisting in the detachment and separation of the support member 200 from the cover body 100. It should be noted that, the width of the guiding groove 210 is smaller than the cross-sectional width of the top of the limiting post 110, so as to stop at the top of the limiting post 110, and the width of the offset groove 215 is larger than the cross-sectional width of the top of the limiting post 110, so as to be able to separate from the limiting post 110 upwards.
Specifically, as shown in fig. 11 and 12, the limiting post 110 includes a post 111 and a circular table 112 located at the top end of the post 111, a step surface is formed between the circular table 112 and the post 111, and one end of the post 111 away from the circular table 112 is fixedly connected with the cover 100, the width of the guide slot 210 is smaller than the diameter of the circular table 112, and the width of the offset slot 215 is larger than the diameter of the circular table 112. As shown in fig. 1, 3 and 11, the guide groove 210 has an arc-shaped bar shape, and the offset groove 215 has an arc-shaped block shape. Thus, when the support 200 is locked with the cover 100, i.e., the cover 100 is rotated in a state of closing the ring lock center post 150, the post 111 of the limit post 110 is inserted into the guide slot 210 and stopped at the top surface of the guide slot 210 by the round table 112, i.e., the guide slot 210 is stopped at the lower side of the round table 112, so that the guide slot 210 cannot be separated from the limit post 110 upwards, when the support 200 is removed, the rotary operation member 260 is rotated so that the center post 150 is not locked by the closing ring, when the cover 100 is rotated, the support 200 is eccentrically rotated with respect to the cover 100, and the limit post 110 slides with respect to the offset slot 215, and when the eccentric rotation is performed so that the center post 150 moves out of the notch 261, the clamping slot 250 of the support 200 is separated from the center post 150, and the offset slot 215 can be separated from the limit post 110 upwards because the width of the offset slot 215 is larger than the width of the round table 112, so that the support 200 can be taken up and separated from the cover 100.
Further, fig. 1 also shows the sliding track ranges of the limiting post 110 and the connecting post 130 when the supporting member 200 rotates relative to the center of the cover 100, and the rotation angles thereof are all along y-y to x-x. When the supporting member 200 eccentrically rotates relative to the connecting post 130 of the cover 100, the center post 150 is offset relative to the clamping slot 250, and the limiting post 110 is offset relative to the offset slot 215, wherein the offset track is shown in fig. 3, the rotation angle is the rotation along x-x to z-z, the offset tracks of the two limiting posts 110 in the corresponding offset slots 215 are different, and as can be seen in fig. 3, the offset track of the limiting post 110 in the offset slot 215, which is farther from the center hole 230, is longer.
Here, it should be understood that the rotation angles and the sliding track of the limiting post 110 and the connecting post 130 may be adjusted by a gear assembly, and the rotation angles of the two may be set to be the same or different, which is not illustrated herein.
In an embodiment according to the present invention, as shown in fig. 2,4 and 6, the rotation operation member 260 includes a rotation post 265 and an operation portion 266 at an upper end of the rotation post 265. The support 200 includes a fixing portion 280 at a lower end and a top cover 290 snap-coupled to a top surface of the fixing portion 280, and an accommodating space is formed between the top cover 290 and the fixing portion 280. The top cover 290 is provided with a through hole for exposing the operation portion 266, and the operation portion 266 protrudes outside the support 200 through the through hole of the top cover 290, so that the operation portion 266 is rotated to press or rotate the rotation operation member 260. In addition, a baffle 267 is fixedly connected between the rotating column 265 and the operating portion 266, the baffle 267 is formed by protruding the lower end of the operating portion 266, and the width of the baffle 267 is larger than that of the rotating column 265, so that a step surface is formed between the baffle 267 and the rotating column 265. As shown in fig. 2 and 4, the rotation post 265 is received in the catching groove 250, the operation portion 266 protrudes outside the support 200 to facilitate operation, and the blocking plate 267 may be stopped at the bottom surface of the top cover 290 to limit the rotation operation member 260 from being upwardly separated from the support 200.
Further, as shown in fig. 6, two plugging columns 269 are symmetrically disposed at two ends of the baffle 267, and the plugging columns 269 can be plugged into and snap-connected with the plugging holes (not shown) of the upper top cover 290, and the plugging columns 269 can be separated from the plugging holes by pressing the rotating operation member 260, so that the rotating operation member 260 can be selected. Here, as shown in fig. 2 and fig. 4, the top end surfaces of the baffle 267 and the shaft seat 220 are located in the accommodating space between the top cover 290 and the fixing portion 280, and a space with a certain height is provided between the baffle 267 and the top end surface of the shaft seat 220, and an elastic member, which may be a spring 240, may be sleeved on the rotation operation member 260, and the spring 240 abuts against the top end surface of the baffle 267 and the shaft seat 220. Therefore, when the rotary operation member 260 is pressed, the pressing spring 240 is compressed downward, the socket post 269 is disengaged from the socket to rotate the rotary operation member 260, and when the rotary operation member 260 is rotated 180 ° and released, the rotary operation member 260 is restored to its original position by the elastic restoring force of the spring 240, so that the socket post 269 is again clamped in the socket. With the above arrangement, the rotation operation member 260 can only rotate when being pressed, so that the support member 200 is prevented from being accidentally unlocked from the cover 100 due to misoperation.
In addition, as shown in fig. 1 and 3, the top surface of the top cover 290 is also provided with a mark 291. The mark serves to indicate whether the cover 100 and the support 200 are currently in the locked state or the unlocked state.
The drawings of the present invention show only an exemplary structure of a pot cover 300, and correspondingly show the shape and structure of the cover body 100 and the support 200 in the pot cover 300.
