Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of chair 1, and it comprises seat 13, the chair back 12 and handrail 11, and this handrail 11 prolongs the chair back 12 and extends out and keep parallel with seat 13.This chair 1 also comprises fan 111 and supports fan 111 and the connecting rod 113 be connected with chair 1 body, this at least one side of handrail 11 is provided with chute, be provided with the pulley 114 that can slide in chute in chute, pulley 114 is fixedly connected with by fixture with connecting rod 113.By the slip drivening rod 113 of pulley in chute 114 and the movement of fan 111, fan 111 can be made to need adjustablely to blow to different directions and position according to user, and user uses convenient and comfortable.Further, for ease of the slip of pulley 114 and the connection with connecting rod 113, in the present embodiment, the chute of art chute designs to be cross section be T-shape, this chute comprises the notch 118 that is positioned at handrail 11 outer surface and is positioned at the guide groove 117 be connected with notch 118 inside handrail 11.Further, for ease of taking off and provided with fan 111 from chair 1, with clean or replacing fan 111, this chute is set to through whole handrail 11, and guide groove 117 extends to the end face at handrail 11 two ends, and pulley 114 can be taken off from handrail 11.
As shown in Figure 2, after user regulates fan 111 position, for ease of fan attachment 111 position, pulley 114 is fixedly connected with by fixture with connecting rod 113.This fixture comprises holding screw 116 and cover plate 115, and cover plate 115 covers pulley 114 and connecting rod 113 coupling part, and the fastening cover plate 115 of holding screw 116, connecting rod 113 and pulley 114 are in handrail 11 side.Before regulating next time, user unclamps holding screw 116 i.e. adjustable fan 111 position, tightens holding screw 116 again after having regulated.Understandable, this fixture can be directly use screw to be fixed on pulley by connecting rod, also can be that connecting rod and pulley are one-body molded.In other embodiments, this pulley can directly be fixedly connected with connecting rod.
Further, chair is also provided with power supply (not shown), and power supply is electrically connected with fan, and wherein, in the present embodiment, power supply, for seeing charge power supply, is moved chair to facilitate user and used local arbitrarily, reduce power line to the constraint of chair.
As shown in Figure 1, for further increasing circulation and the radiating effect of air, on the chair back 12 of chair 1 He on seat 13, be also provided with passage 121, in other embodiments, chute can also be set on the chair back 12, for arranging fan 111 on the chair back 12 simultaneously.For further utilizing the space of chair 1, convenient for collecting, below seat 13, be provided with drawer 14, for receiving foreign material etc.
Further, be adding users comfort, this fan 111 is also provided with humidifier 112.In use occur injured risk for reducing user, the fan 111 adopted in present embodiment is without blade fan 111.
As shown in Figure 3, this connecting rod 113 comprises contractile multistage cylindrical shell, is fixedly connected with between this multistage cylindrical shell by spring by card 1133.In the present embodiment, connecting rod 113 comprises two sections of cylindrical shells, first cylindrical shell 1132 diameter is greater than the second cylindrical shell 1131, so that the second cylindrical shell 1131 is accommodated in the first cylindrical shell 1132, this the second cylindrical shell 1131 bottom is provided with spring by card 1133, to block the first cylindrical shell 1132 when the second cylindrical shell 1131 stretches out the first cylindrical shell 1132 and to fix.This spring is a spring by the structure of card 1133 and is arranged at the convex of spring top and buckles.User use be can as required at any time the height of regulating connecting rod 113 so that wind is toward different positions.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
