DETAILED DESCRIPTION

[0017] In order to make the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the given embodiment is only one implementation method and does not represent all embodiments.

[0018] Example 1

[0019] Combine Figure 1-Figure 3This embodiment provides an automatic opener and closeer for a gas cylinder valve, comprising a control assembly, a lifting assembly, and a rotating assembly. One end of the lifting assembly is fixed to the gas cylinder 5. The control assembly comprises a control mainboard 102. The rotating assembly comprises a motor 201 electrically connected to the control mainboard 102. The output end of the motor 201 is connected to a transmission shaft 202. A valve clamp is fixed to an end of the transmission shaft 202 away from the motor 201. A rotating member 203 for controlling the engagement of the valve clamp with the valve 501 is rotatably connected to the transmission shaft 202.

[0020] In this embodiment, the control main board 102 is electrically connected to the motor 201, and the motor 201 drives the transmission shaft 202 to rotate, and then drives the valve clamp to rotate, thereby automatically opening and closing the valve 501; moreover, the expansion and contraction of the valve clamp can be customized to match different types of gas cylinders 5, and there is no need to customize the valve clamp according to the size of each gas cylinder 5 or the size of the valve 501, thereby saving the cost of use; in addition, the use of a lifting component with one end fixed to the gas cylinder 5 can not only increase the stability of the automatic opener, but also can adjust the height according to the distance between the valve 501 and the gas cylinder 5 body, further matching different types of gas cylinders 5.

[0021] Specifically, the valve clamp includes a connecting portion 401, which is fixedly connected to the transmission shaft 202. A plurality of retractable plates 402 are spaced apart and connected to the circumferential ends of the connecting portion 401. The ends of the retractable plates 402, which are away from the connecting portion 401, are engaged with the valve 501. A knob 404 is provided on the end of the retractable plates 402 connected to the connecting portion 401. The connecting portion 401 is provided with guide grooves 403 corresponding in number and position to the knobs 404. The rotating member 203 is threadedly connected to the transmission shaft 202. The rotating member 203 is provided with a plurality of arcuate grooves 405 extending therethrough. The arcuate grooves 405 correspond in number and position to the knobs 404. The knobs 404 sequentially pass through the guide grooves 403 and the arcuate grooves 405. Preferably, in this embodiment, the connecting portion 401 is evenly distributed with three retractable plates 402, each of which has one end provided with the knob 404 and is respectively located within the connecting portion 401 and is slidable within the connecting portion 401. The guide groove 403 is a linear groove along the radial direction of the connecting portion 401, which limits the movement direction of the convex button 404, that is, it can drive the telescopic plate 402 to retract or extend along the radial direction of the connecting portion 401, so that the telescopic plate 402 can clamp the valves 501 of gas cylinders 5 of different sizes.

[0022] The arc groove 405 provided on the rotating member 203 can provide the power for the convex button 404 to retract or extend. When in use, the rotating member 203 can be manually rotated counterclockwise or clockwise. Since the rotating member 203 and the transmission shaft 202 are threadedly connected, the rotating position of the rotating member 203 can be fixed at any time.

[0023] Specifically, the rotating member 203 is circumferentially connected to a handpiece 406, which facilitates manual operation of the rotating member 203. In this preferred embodiment, the handpiece 406 is snap-fitted to the rotating member 203. It should be understood that the handpiece 406 can also be welded to the rotating member 203. A motor housing 204 is provided on the exterior of the motor 201. The output end of the motor 201 is located outside the motor housing 204 to ensure a certain distance between the motor 201 and the lower rotating member 203, preventing the motor 201 from interfering with the relative motion of the knob 404 and the rotating member 203.

[0024] Specifically, the control assembly also includes a control housing 103 and an operating screen 101 electrically connected to a control mainboard 102. The lifting assembly includes an electric push rod 301, one end of which is provided with a clamping ring 302, and the other end of which is fixed to the side wall of the control housing 103. The clamping ring 302 is detachably fixed to the gas cylinder 5, and the push rod 301 is electrically connected to the control mainboard 102. The control mainboard 102 controls the extension and retraction of the push rod 301, which drives the valve 501 up and down, thereby enabling the valve 501 to be placed and retrieved.

[0025] When in use, first fix the clamping ring 302 on the gas cylinder 5, then adjust the electric push rod 301 to make the height position of the telescopic plate 402 correspond to the valve 501, rotate the handpiece 406, so that the rotating part 203 drives the telescopic plate 402 to extend or retract, so that the telescopic plate 402 can clamp or loosen the valve 501, thereby stably fixing the automatic switch and the valve 501. When the valve 501 needs to be closed or opened, it is only necessary to click the operation screen 101, and the motor 201 receives the signal to drive the transmission shaft 202 to rotate, thereby driving the telescopic plate 402 to rotate to close or open the valve 501.

[0026] The above describes the specific embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the described embodiments. It is clear to those skilled in the art that various changes, modifications, substitutions, and variations of these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
