[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a pull-wire valve, including a first fixing plate 1 and a pull-wire valve body 2. The pull-wire valve body 2 is detachably connected to one side of the first fixing plate 1, and a connecting frame 3 is fixedly connected to one side of the pull-wire valve body 2. A connecting hole 20 penetrating through its surface is opened on one side of the first fixing plate 1. A connecting cylinder 5 is detachably connected inside the connecting hole 20 and enters the connecting frame 3 through the connecting hole 20. A second fixing plate 4 is fixedly connected to one side of the connecting cylinder 5. A sliding groove 6 penetrating through its surface is opened on one side of the second fixing plate 4. A movable plate 7 is slidably connected inside the sliding groove 6 and moves along the inside of the sliding groove 6. An arc-shaped plate 10 is fixedly connected to one side of the movable plate 7 and moves the movable plate 7 along with it. A connecting block 11 is fixedly connected to the outer side of the arc-shaped plate 10 away from the movable plate 7 and moves the connecting block 11 along with it, so that the connecting block 11 moves to the outside of the connecting frame 3 and fixes the connecting cylinder 5 inside the connecting frame 3.

[0025] Furthermore, the second fixing plate 4 is located on one side of the connecting cylinder 5 and is fixedly connected to a hollow rod 8 via a support frame. A connecting rod 9 is slidably connected inside the hollow rod 8. Connecting grooves are provided on both sides of the inner wall of the hollow rod 8. Slider blocks are fixedly connected to both sides of the connecting rod 9. The outer side of the slider is slidably connected to the connecting groove and fits against the connecting groove.

[0026] Furthermore, the second fixing plate 4 has a threaded post 12 inside, one end of which passes through one side of the second fixing plate 4 and is fixedly connected to the connecting rod 9. The movement of the threaded post 12 moves the connecting rod 9.

[0027] Furthermore, an adjusting rod 17 is rotatably connected to the outer side of the connecting rod 9. The movement of the connecting rod 9 causes the adjusting rod 17 to move as well. The end of the adjusting rod 17 away from the connecting rod 9 is rotatably connected to the arc plate 10, and the adjusting rod 17 causes the arc plate 10 to move as well.

[0028] Furthermore, a ratchet 16 is rotatably connected to one side of the second fixed plate 4, and a threaded sleeve 13 is fixedly connected to the side of the ratchet 16 away from the second fixed plate 4. The outer side of the threaded post 12 is threadedly connected to the threaded sleeve 13. When the threaded sleeve 13 rotates, it causes the ratchet 16 to rotate. When the threaded sleeve 13 rotates, the threaded post 12 moves.

[0029] Furthermore, a pawl 14 is rotatably connected to one side of the second fixed plate 4. A torsion spring 15 is fixedly connected between the pawl 14 and the second fixed plate 4. When the pawl 14 rotates, the torsion spring 15 deforms. When the torsion spring 15 loses its force, under the action of the elastic force, the torsion spring 15 carries the pawl 14 back to its original position. The pawl 14 works in conjunction with the ratchet 16. The pawl 14 is locked between the two teeth of the ratchet 16 to prevent the ratchet 16 from reversing.

[0030] Furthermore, a first spring 18 is fixedly connected between one end of the connecting rod 9 and the hollow rod 8. When the connecting rod 9 moves, it compresses the first spring 18. When the first spring 18 loses its compressive force, it returns to its original position along with the connecting rod 9.

[0031] Furthermore, a turntable 19 is fixedly connected to the outer side of the threaded sleeve 13 to better rotate the threaded sleeve 13.

[0032] In use, the connecting cylinder 5 is inserted through the connecting hole 20 into the connecting frame 3 on one side of the first fixing plate 1 and the pull valve body 2. The turntable 19 rotates the threaded sleeve 13, which in turn moves the threaded column 12. The movement of the threaded column 12 moves the connecting rod 9 toward the hollow rod 8. The movement of the connecting rod 9 moves the arc plate 10 through the adjusting rod 17. The arc plate 10 gradually approaches the inner wall of the connecting frame 3, and the connecting block 11 contacts the top of the end of the connecting frame 3 away from the pull valve body 2. The connecting cylinder is then placed... 5 is fixed within the first fixing plate 1, the pull-line valve body 2, and the connecting frame 3, so that the first fixing plate 1 and the pull-line valve body 2 are connected together. When the threaded sleeve 13 rotates, it causes the ratchet 16 to rotate and press against the pawl 14. The pawl 14 rotates with the torsion spring 15. After the pressing force is lost, under the action of the torsion spring 15, the threaded sleeve 13 and the pawl 14 return to their original position and are locked in the teeth on the outside of the ratchet 16, preventing the ratchet 16 and the threaded sleeve 13 from reversing, and further strengthening the connection between the first fixing plate 1 and the pull-line valve body 2.
