技术领域technical field
本发明涉及压力锅技术领域，特别是一种压力锅锁盖结构。The invention relates to the technical field of pressure cookers, in particular to a pressure cooker cover locking structure.
背景技术Background technique
以目前的电压力锅为例，其包括锅体和锅盖，锅体内顶部环形布置有凹凸相间的锅牙，锅盖内壁对应锅牙设有扣位，通过旋转锅盖使得扣位处于凸出的锅牙下方，实现锅盖与盖体扣接，反之，扣位随同锅盖旋转至凹入的锅牙下方时，锅盖即可翻起或打开。由于锅内气压较高时开盖存在危险性，因此，现有的压力锅，均有一套自锁机构，自锁机构包括随着锅内气压变化而上下浮动的气浮阀、横向滑动设置在锅盖内的锁销组件，锁销组件一端贴着锅体的锅牙表面，锁销组件另一端延伸至气浮阀处，正常情况下，如果锅内气压较低（安全开盖气压），气浮阀不会阻挡锁销组件，锅盖旋转打开时，锁销组件沿锅体锅牙表面自由活动，不影响开盖；反之，当锅内气压过高时，气浮阀阻挡锁销组件，以致锁销组件不能沿锅体锅牙表面自由活动，因此锅盖不能旋转，以致不能开盖。当然，以上所述只是理论的状态，但该结构实际上还是存在一定的安全隐患，因为气浮阀与锁销组件之间必然存在一定的虚位（如果没有虚位气浮阀将会被卡死），即使锅内高气压的情况下，如果作用于锅盖的旋转开盖作用力较大时，锁销组件可克服气浮阀的阻力，并改变气浮阀的状态，就能在这种不利于开盖的状态下开盖，从而带来巨大的安全隐患，因此需要对该结构进行改进。Taking the current electric pressure cooker as an example, it includes a pot body and a pot cover. The top of the pot body is annularly arranged with concavo-convex pot teeth, and the inner wall of the pot cover is provided with buckles corresponding to the pot teeth. Under the pot teeth, the pot lid is buckled with the lid body. On the contrary, when the buckle rotates with the pot cover to the bottom of the recessed pot teeth, the pot lid can be turned up or opened. Because there is danger in opening the lid when the air pressure in the pot is high, the existing pressure cookers all have a set of self-locking mechanisms. The lock pin assembly inside the cover, one end of the lock pin assembly is attached to the surface of the pot teeth of the pot body, and the other end of the lock pin assembly extends to the air valve. The float valve will not block the lock pin assembly. When the lid is rotated and opened, the lock pin assembly can move freely along the surface of the pot teeth without affecting the opening of the lid; on the contrary, when the pressure in the pot is too high, the air float valve blocks the lock pin assembly. As a result, the lock pin assembly cannot move freely along the surface of the pot teeth of the pot body, so the pot cover cannot rotate, so that the cover cannot be opened. Of course, the above is only a theoretical state, but there are still certain potential safety hazards in this structure, because there must be a certain virtual position between the air flotation valve and the lock pin assembly (if there is no vacant position, the air flotation valve will be stuck. dead), even in the case of high pressure in the pot, if the force acting on the rotation and opening of the pot lid is large, the lock pin assembly can overcome the resistance of the air flotation valve and change the state of the air flotation valve, so that Opening the cover in a state that is not conducive to opening the cover will bring huge potential safety hazards, so the structure needs to be improved.

The button body 1 is movable to limit the position and is arranged on the pot cover 3. The first return spring 2 is arranged between the button body 1 and the pot cover 3, and the button body 1 is provided with the push rod 11 that is used for touching connecting rod 5.
所述按钮本体1竖直活动设置在锅盖3上，连杆5与顶杆11通过斜面传动配合。所述连杆5对应顶杆11设有楔块4，顶杆11下端设有推顶斜面与楔块4传动配合。参见图6中C处和图7中D处，分别为按钮本体1中推顶斜面的两种设计方式。The button body 1 is vertically movably arranged on the pot cover 3, and the connecting rod 5 and the ejector rod 11 are matched by transmission through an inclined plane. The connecting rod 5 is provided with a wedge 4 corresponding to the ejector rod 11, and the lower end of the ejector rod 11 is provided with a push-out inclined surface and the wedge 4 is in transmission cooperation. Referring to point C in FIG. 6 and point D in FIG. 7 , there are two design modes of the pushing slope in the button body 1 respectively.
所述锅盖3包括外盖32和内盖33，所述上锅牙332设置在内盖33内周；所述锁销52指向锅体8中心的一端设有球形头，锁销52背向锅体8中心的一端设有定位销51，外盖32对应定位销51设有第一通孔321，内盖33对应锁销52设有第二通孔331，定位销51和锁销52分别承接在第一通孔321内和第二通孔331内。The pot cover 3 includes an outer cover 32 and an inner cover 33, and the upper pot tooth 332 is arranged on the inner periphery of the inner cover 33; the end of the lock pin 52 pointing to the center of the pot body 8 is provided with a spherical head, and the lock pin 52 faces away from the One end of the center of the pot body 8 is provided with a positioning pin 51, the outer cover 32 is provided with a first through hole 321 corresponding to the positioning pin 51, and the inner cover 33 is provided with a second through hole 331 corresponding to the locking pin 52, and the positioning pin 51 and the locking pin 52 are respectively Received in the first through hole 321 and the second through hole 331 .
所述定位销51上套设有第二复位弹簧6，第二复位弹簧6压接在外盖32与连杆5之间。The positioning pin 51 is sleeved with a second return spring 6 , and the second return spring 6 is pressed between the outer cover 32 and the connecting rod 5 .
所述外盖32顶部设有手柄31，按钮本体1设置在手柄31上。The top of the outer cover 32 is provided with a handle 31 , and the button body 1 is arranged on the handle 31 .
所述锅体8内部设有顶部敞开的凹腔，凹腔内设有内壳7，内壳7顶端伸至锅体8顶部，内壳7顶端设有外翻边；所述外翻边外周凹凸相间，其凸部形成为所述下锅牙71。The inside of the pot body 8 is provided with a concave cavity with an open top, and an inner shell 7 is arranged in the concave cavity, and the top of the inner shell 7 extends to the top of the pot body 8, and the top of the inner shell 7 is provided with an outer flange; Concave and convex are alternated, and the convex part is formed as the lower pot teeth 71 .
其工作原理是：在锅盖3解锁状态时，通过正向旋转锅盖3，锅盖3的锁销52与下锅牙71的引导斜面接触，所以能够随下锅牙71表面形状运动，直至锅盖3与锅体8扣接后，锁销52与下锅牙71的阻挡边712（直边）相挡，锁销52不能沿阻挡边712滑动，因此，锅盖3不能反向旋转解锁，此时需通过按下按钮本体1，按钮本体1通过连杆5带动锁销52退出阻挡边712，即可进行锅盖3反向旋转操作，实现解锁。Its working principle is: when the pot cover 3 is unlocked, by rotating the pot cover 3 forward, the lock pin 52 of the pot cover 3 is in contact with the guiding slope of the lower pot tooth 71, so it can move with the surface shape of the lower pot tooth 71 until After the pot cover 3 is fastened to the pot body 8, the lock pin 52 is blocked by the blocking edge 712 (straight edge) of the lower pot tooth 71, and the lock pin 52 cannot slide along the blocking edge 712, therefore, the pot cover 3 cannot be unlocked by reverse rotation At this time, the button body 1 needs to be pressed, and the button body 1 drives the lock pin 52 to withdraw from the blocking edge 712 through the connecting rod 5, so that the pot cover 3 can be reversely rotated to realize unlocking.
实施例二，与实施例一的区别在于：参见图8所示，取消按钮本体1等相关零件，而直接在定位销51伸出锅盖3外的一端上设置拉柄9，当锁销与阻挡边相挡时，通过往外拉住拉柄9，才能使得锁销离开阻挡边，此时才能转动锅盖。该结构只是控制锁销复位的方式与实施例一的方式不同，但原理相同，在此不再详述。Embodiment two, the difference with embodiment one is: referring to shown in Fig. 8, cancel button body 1 and other relevant parts, and directly set handle 9 on the end that locating pin 51 stretches out pot cover 3, when locking pin and When the blocking side blocks each other, by pulling the handle 9 outwards, the lock pin can be made to leave the blocking side, and now the pot cover can be rotated. This structure is only different in the way of controlling the reset of the lock pin from that in Embodiment 1, but the principle is the same, and will not be described in detail here.
