Description

Technical Field

[0001] This utility model relates to the field of valve handwheel technology, specifically a foldable and concealable valve handwheel. Background Technology

[0002] Valves are mechanical devices that control the flow rate, direction, pressure, temperature, etc. of flowing fluid media. Valves are basic components in pipeline systems. Technically, valve fittings, like pumps, are often discussed as a separate category. Valves can be operated manually or by handwheel, handle, or pedal.

[0003] According to a foldable and concealable valve handwheel disclosed in the above application (Announcement No.: CN220302901U), when using the valve handwheel, the folding structure can be used to fold the valve handwheel when it is not in use, so as to minimize the space occupied by the valve handwheel when it is stored. And through the limiting structure, the handwheel and valve can be separated when the valve handwheel is not needed, thus avoiding accidental operation by unauthorized personnel.

[0004] However, in actual use, the gaps between the folding structures of the above-mentioned equipment are relatively large when the equipment is not folded, which makes it easy for the torque generated when the operator turns the valve handwheel to cause the folding structure to break, thus preventing the valve from opening in time. In view of this, we propose a foldable and retractable valve handwheel. Utility Model Content

[0005] The purpose of this invention is to provide a foldable and concealable valve handwheel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable and concealable valve handwheel, comprising a valve handwheel body, wherein a folding assembly is provided on the inner wall of the valve handwheel body, the folding assembly comprising:

[0007] The mounting component is fixedly connected to the inner wall of the valve handwheel body. A movable rod is rotatably connected to the inner wall of the mounting component. A locking block is fixedly connected to the end of the movable rod. An embedding groove is provided on the side of the locking block.

[0008] A limiting component is fixedly connected to the inner wall of the valve handwheel body. A placement groove is provided on the side of the inner wall of the limiting component, and a moving groove is provided on the inner wall of the placement groove.

[0009] A small spring is fixedly connected to the side of the inner wall of the placement groove. An embedded block is fixedly connected to the end of the small spring, and a moving block is fixedly connected to the side of the embedded block.

[0010] Preferably, the size of the movable block is adapted to the size of the movable slot, and the movable block is disposed inside the movable slot, which allows the movable block to move inside the movable slot.

[0011] Preferably, the embedding block is disposed inside the placement slot, and the position of the embedding block corresponds to the position of the embedding slot, so that the embedding block can be well inserted into the embedding slot.

[0012] Preferably, the position of the mounting component corresponds to the position of the limiting component, and the mounting component is U-shaped, which makes the movable rod more convenient to move.

[0013] Preferably, the outer surface of the movable rod is provided with an auxiliary component, the auxiliary component including a fixing ring, the fixing ring being fixedly connected to the outer surface of the movable rod, a large spring being fixedly connected to the side of the fixing ring, a pressing member being fixedly connected to the end of the large spring, a limit ring being fixedly connected to the outer surface of the movable rod, and an embedding hole being provided on the upper surface of the mounting component.

[0014] Preferably, the limiting ring is disposed on the side of the pressing member near the mounting member, and the pressing member is composed of a pressing plate with a protruding rod fixedly connected to the side, and the position of the protruding rod corresponds to the position of the embedding hole.

[0015] Compared with the prior art, this utility model provides a foldable and concealable valve handwheel, which has the following advantages:

[0016] 1. To prevent damage to the valve handwheel due to excessive torque when turning it, this foldable and concealable valve handwheel allows the operator to move the movable block when the operator needs to apply more force to turn the handwheel. This causes the embedded block to compress the small spring, displacing the embedded block from the embedded groove. Then, the movable rod is moved so that it is perpendicular to the valve handwheel body. This makes it easier for the operator to grip and turn the handwheel. The movable rod is fixedly connected to the valve handwheel body via a mounting bracket, preventing breakage under stress. When not in use, the movable rod can be folded away by inserting the locking block into the limiting component.

[0017] 2. To make the valve handwheel more stable when rotating, the foldable and concealed valve handwheel features a mechanism where, when the movable rod moves, the pressing component is moved first, pressing against the large spring. When the movable rod is perpendicular to the valve handwheel body, the pressing component is released, causing the spring force to push the pressing component downwards. This allows the protrusion on the side of the pressing component to engage with the embedded hole, thus limiting the movable rod and making it more stable for the operator to hold the movable rod and rotate the valve handwheel body.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a foldable and concealable valve handwheel, including a valve handwheel body 1, and a folding assembly 2 provided on the inner wall of the valve handwheel body 1. The folding assembly 2 includes an installation component 201, a movable rod 203, a locking block 204, an embedding groove 205, a limiting component 202, a placement groove 206, a moving groove 208, a small spring 207, an embedding block 209, and a moving block 210.

[0024] In this embodiment of the present invention, the mounting member 201 is fixedly connected to the inner wall of the valve handwheel body 1. The position of the mounting member 201 corresponds to the position of the limiting member 202. The mounting member 201 is U-shaped, which makes it easier for the movable rod 203 to move. The movable rod 203 is rotatably connected to the inner wall of the mounting member 201. A locking block 204 is fixedly connected to the end of the movable rod 203. An embedding groove 205 is provided on the side of the locking block 204. The limiting member 202 is fixedly connected to the inner wall of the valve handwheel body 1. A placement groove 206 is provided on the side of the inner wall of the limiting member 202. A moving part is provided on the inner wall of the placement groove 206. The moving groove 208 and the small spring 207 are fixedly connected to the inner wall side of the placement groove 206. The end of the small spring 207 is fixedly connected to the embedding block 209. The embedding block 209 is set inside the placement groove 206. The position of the embedding block 209 corresponds to the position of the embedding groove 205, so that the embedding block 209 can be well inserted into the embedding groove 205. The side of the embedding block 209 is fixedly connected to the moving block 210. The size of the moving block 210 is adapted to the size of the moving groove 208. The moving block 210 is set inside the moving groove 208, so that the moving block 210 can move inside the moving groove 208.

[0025] Meanwhile, an auxiliary component 3 is provided on the outer surface of the movable rod 203. The auxiliary component 3 includes a fixing ring 301, which is fixedly connected to the outer surface of the movable rod 203. A large spring 303 is fixedly connected to the side of the fixing ring 301, and a pressing member 304 is fixedly connected to the end of the large spring 303. The pressing member 304 is composed of a protruding rod fixedly connected to the side of the pressing plate, and the position of the protruding rod corresponds to the position of the embedding hole 305. A limiting ring 302 is fixedly connected to the outer surface of the movable rod 203. The limiting ring 302 is located on the side of the pressing member 304 near the mounting member 201. An embedding hole 305 is provided on the upper surface of 201. This allows the pressing member 304 to move first when the movable rod 203 moves, so that the pressing member 304 presses the large spring 303. When the movable rod 203 is set perpendicular to the valve handwheel body 1, the pressing member 304 is released. This allows the elastic force of the large spring 303 to push the pressing member 304 downward, so that the protrusion provided on the side of the pressing member 304 is inserted into the embedding hole 305. This limits the movable rod 203, making it more stable for the operator to hold the movable rod 203 and turn the valve handwheel body 1.

[0026] In this utility model, when the operator needs to increase the force to turn the valve handwheel body 1, the moving block 210 is moved to cause the embedded block 209 to compress the small spring 207 and retract. This causes the embedded block 209 to move out of the embedded groove 205. Then the movable rod 203 is moved so that the movable rod 203 is set perpendicular to the valve handwheel body 1. This makes it easier for the operator to hold and turn the valve handwheel body 1. The movable rod 203 is fixedly connected to the valve handwheel body 1 by the mounting part 201, which will not break when the movable rod 203 is under force. At the same time, when the movable rod 203 is not in use, the locking block 204 is inserted into the limiting part 202 to fold and retract the movable rod 203.

[0027] Furthermore, when the movable rod 203 moves, the pressing member 304 is moved first, so that the pressing member 304 presses the large spring 303. When the movable rod 203 is set perpendicular to the valve handwheel body 1, the pressing member 304 is released. This allows the elastic force of the large spring 303 to push the pressing member 304 downward, so that the protrusion on the side of the pressing member 304 is inserted into the embedded hole 305. This limits the movable rod 203, making it more stable for the operator to hold the movable rod 203 and turn the valve handwheel body 1.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
