Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, and in particular to a quick-opening and closing device for a hand-cranked gate. Background Technology

[0002] In the field of gate control technology, traditional threaded rod transmission mechanisms typically use a direct rotating screw to drive the gate movement. Although this structure is simple, in actual use, because the threaded rod is directly connected to the gate, accidental rotation of the threaded rod due to operator error or external force can lead to unexpected displacement of the gate, seriously affecting the safety and reliability of equipment operation. Therefore, this solution proposes a hand-cranked gate quick opening and closing device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a quick-opening and closing device for a hand-cranked gate, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hand-cranked gate quick-opening and closing device, applied at the connection between the frame and the threaded rod, comprising:

[0010] Preferably, a second bearing is sleeved on the outer wall of the connecting shaft, and the second bearing is inserted and connected to the middle of the rotating frame.

[0011] Preferably, the limiting member includes multiple locking holes formed in the middle of the rotating block, one of the locking holes having a locking block inserted inside it, the locking block being inserted into the front of the fixed frame, and limiting rings being symmetrically arranged at the top and bottom of the rotating block.

[0012] Preferably, a pressing block is fixedly connected to one end of the card block, and a spring is provided on the back of the pressing block.

[0013] Preferably, a fixing ring is fixedly connected to the front of the fixing frame, and the fixing ring is used to limit the movement distance of the pressing block.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention, through the design of a fixed frame, a first bearing, a first bevel tooth, an insertion groove, a second bevel tooth, a rotating component, a moving component, a rotating block, and a limiting component, ensures that when the threaded rod needs to be rotated, the limiting component first restricts the rotation of the rotating block, the moving component drives the second bevel tooth to mesh with the first bevel tooth, and finally the rotating component drives the second bevel tooth to rotate while simultaneously moving the threaded rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 Shown:

[0023] Example 1: A hand-cranked gate quick-opening and closing device, applied at the connection between the frame 1 and the threaded rod 2, includes:

[0024] Fixed frame 3 is fixedly connected to the top of frame 1;

[0025] Rotating assembly 4 includes a first bearing 404 inserted inside the fixed frame 3. The bottom end of the first bearing 404 is provided with a first bevel tooth 405. The first bevel tooth 405 is threaded onto the top of the threaded rod 2. A through groove 402 is opened on one side of the fixed frame 3. A second bevel tooth 406 is provided on one side of the first bevel tooth 405. A rotating part is provided on one side of the second bevel tooth 406. A moving part is provided on one side of the second bevel tooth 406.

[0026] Locking component 5 includes a rotating block 507 threaded onto the bottom of the threaded rod 2, and a limiting element is provided on one side of the rotating block 507.

[0027] It should be noted that the fixed frame 3 is a square frame. The outer groove ring of the first bearing 404 is fixedly connected to the inside of the fixed frame 3, and its inner groove ring is fixedly connected to the first bevel tooth 405. This ensures that the position of the first bevel tooth 405 is fixed without affecting its rotation. The first bevel tooth 405 is threaded onto the threaded rod 2. When the threaded rod 2 needs to be moved, the rotation of the rotating block is first restricted by the limiting component. The moving component drives the second bevel tooth 406 to mesh with the first bevel tooth 405. Finally, the rotating component drives the second bevel tooth 406 to rotate while simultaneously moving the threaded rod 2. This ensures that the rotation of the threaded rod 2 requires multiple steps, preventing the threaded rod 2 from being rotated arbitrarily.

[0028] Specifically, the movable component includes a rotating frame 403 hinged to the middle of the fixed frame 3, an elliptical cylinder 407 hinged to one side of the rotating frame 403, a pressing handle 408 provided on one side of the elliptical cylinder 407, and the rotating component is located on one side of the rotating frame 403.

[0029] It should be noted that the rotating frame 403 is connected to the fixed frame 3 by a hinge, so that the rotating frame 403 can rotate on the fixed frame 3. When it is necessary to engage the second bevel tooth 406 with the first bevel tooth 405, the elliptical cylinder 407 is rotated, which presses the rotating frame 403, and the rotating frame 403 drives the second bevel tooth 406 to engage with the first bevel tooth 405.

[0030] Specifically, the rotating component includes a connecting shaft 409 fixedly connected to one side of the second bevel gear 406, a rotating handle 401 fixedly connected to one side of the connecting shaft 409, and a second bearing 410 sleeved on the outer wall of the connecting shaft 409, which is inserted into the middle of the rotating frame 403.

[0031] It should be noted that the second bearing 410 is an existing ball bearing. In use, the second bearing 410 connects the rotating frame 403 and the connecting shaft 409, so that the position of the connecting shaft 409 is fixed while it can rotate. The rotating handle 401 is used to rotate the connecting shaft 409, and the connecting shaft 409 drives the second bevel gear 406 to rotate.

[0032] Example 2: A limiting component, applied to the opening and closing device in Example 1;

[0033] Specifically, the limiting components include multiple locking holes 503 formed in the middle of the rotating block 507, with a locking block 506 inserted inside one of the locking holes 503. The locking block 506 is inserted into the front of the fixed frame 3. Restricting rings 501 are symmetrically arranged at the top and bottom of the rotating block 507. A pressing block 505 is fixedly connected to one end of the locking block 506. A spring 504 is provided on the back of the pressing block 505. A fixing ring 502 is fixedly connected to the front of the fixed frame 3. The fixing ring 502 is used to limit the movement distance of the pressing block 505.

[0034] It should be noted that the rotating block 507 is a cylinder with a threaded hole in the middle that matches the threaded rod 2, allowing the threaded rod 2 to be threaded through the middle of the rotating block 507. When the position of the threaded rod 2 needs to be moved, the rotation of the rotating block 507 needs to be restricted, so that the rotating threaded rod 2 can move on the rotating block 507 that restricts rotation and displacement. When the restriction on the rotating block 507 is removed, when the threaded rod 2 rotates, the rotating block 507 rotates along with the threaded rod 2, at which point the threaded rod 2 cannot move. Multiple locking holes 503 are arranged in an equidistant circular array on the outer wall of the rotating block 507, and locking blocks 506 are adapted to the locking holes 503. This allows the locking block 506 to be inserted into the locking hole 503. A hole adapted to the locking block 506 is provided on the fixed frame 3, which restricts the movement direction of the locking block 506. The spring 504 is used to drive the locking block 506 to move, so that when it is not necessary to restrict the rotation of the rotating block 507, the locking block 506 can be moved out of the locking hole 503. When it is necessary to restrict the rotation of the rotating block 507, one end of the locking block 506 is moved into the locking hole 503 by pressing the block 505. The blocking block 506 prevents the rotating block 507 from rotating. The limiting ring 501 is fixedly inserted and connected inside the fixed frame 3. The movement of the rotating block 507 is restricted by the two limiting rings 501.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
