DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5As shown, the embodiment of the utility model provides a pump valve that is easy to adjust the engagement height, including a lower base 1, an upper base 2 is arranged above the lower base 1, an adjustment assembly 7 is arranged between the lower base 1 and the upper base 2, and the adjustment assembly 7 includes a support frame 701, an external threaded rod 702, a bearing 703 and an internal threaded sleeve 704, and a support seat 3 is fixedly installed on the upper surface of the upper base 2;

[0027] A limiting assembly 4 is arranged inside the support seat 3, and the limiting assembly 4 includes an arc-shaped limiting plate 401, a groove 402, a connecting rod 403, a movable plate 404 and a spring 405. Two arc-shaped limiting plates 401 are movably arranged inside the support seat 3, and the two arc-shaped limiting plates 401 are symmetrically arranged. Two grooves 402 are provided on the upper surface of the support seat 3, and a connecting rod 403 is fixedly installed between the front side of the inner wall and the rear side of the inner wall of the groove 402. A movable plate 404 is fixedly installed on the lower surface of the arc-shaped limiting plate 401, and the movable plate 404 is movably sleeved on the outer side of the connecting rod 403. A spring 405 is wound around the outer side of the connecting rod 403, and one end of the spring 405 is fixedly connected to the rear side of the inner wall of the groove 402, and the other end of the spring 405 is fixedly connected to the rear side of the movable plate 404.

[0028] In one embodiment, a support frame 701 is fixedly installed on the lower surface of the upper base 2, and an externally threaded rod 702 is fixedly installed on the upper surface of the lower base 1. A limit plate is fixedly installed on the top of the externally threaded rod 702. The support frame 701 is movably arranged on the outside of the externally threaded rod 702. An internally threaded sleeve 704 is rotatably installed on the lower surface of the support frame 701 through a bearing 703. The internally threaded sleeve 704 is threadedly connected to the externally threaded rod 702. A turning handle is fixedly installed on the outside of the internally threaded sleeve 704. The internally threaded sleeve 704 is driven to rotate by the turning handle. The internally threaded sleeve 704 is threadedly matched with the externally threaded rod 702, so that the internally threaded sleeve 704 drives the support frame 701 to move upward under the action of the bearing 703. At the same time, the support frame 701 drives the upper base 2 and the pump valve to move upward, and the height of the pump-valve joint position is adjusted.

[0029] In one embodiment, a first through hole 8 is opened on the upper surface of the support frame 701, and the inner wall of the first through hole 8 is in movable contact with the outer side of the external threaded rod 702, so that the support frame 701 can move on the outer side of the external threaded rod 702 through the provision of the first through hole 8.

[0030] In one embodiment, four square rods 5 are fixedly mounted on the upper surface of the lower base 1, and the four square rods 5 are diagonally arranged. The upper base 2 is movably sleeved on the outer side of the square rods 5. A plurality of square holes 6 are opened on the upper surface of the upper base 2. The inner walls of the square holes 6 are in movably contact with the outer sides of the square rods 5. The square rods 5 cooperate with the square holes 6 to achieve guidance of the upper base 2 when it moves.

[0031] In one embodiment, a second through hole 9 is opened on one side of the movable plate 404 , and the inner wall of the second through hole 9 is in movable contact with the outer side of the connecting rod 403 , so that the movable plate 404 slides on the outer side of the connecting rod 403 through the second through hole 9 .

[0032] The utility model is in operation: when the pump valve needs to be stably placed, the two arc-shaped limit plates 401 are pulled away from each other, at which time the arc-shaped limit plates 401 drive the movable plate 404 to move, and the movable plate 404 moves on the outside of the connecting rod 403 and compresses the spring 405, placing the pump valve on the upper surface of the support seat 3, and then the outward pulling force on the two arc-shaped limit plates 401 is released, the compressed spring 405 is reset, and the movable plate 404 is pushed to move, and the movable plate 404 drives the arc-shaped limit plate 401 to move and contact the outside of the pump valve, and the pump valve is limited under the action of the two arc-shaped limit plates 401;

[0033] When the height of the pump-valve joint position needs to be adjusted, the handle is turned, and the handle drives the internal threaded sleeve 704 to rotate. Since the internal threaded sleeve 704 is threadedly connected to the external threaded rod 702, the internal threaded sleeve 704 is rotatably installed on the lower surface of the support frame 701, and the internal threaded sleeve 704 rotates and pushes the support frame 701 to move upward. At the same time, the support frame 701 moves upward and drives the upper base 2 to move upward. The upper base 2 drives the pump valve to move upward along the multiple square rods 5. After the pump-valve joint position is moved to a suitable height, the handle is stopped from being turned. Under the self-locking of the threads of the internal threaded sleeve 704 and the external threaded rod 702, the height of the pump-valve joint position is locked, making it easy to adjust the height of the pump-valve joint position according to actual needs, thereby improving flexibility during use.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
