[0025] Refer to Figure 1 Figure 2 and Figure 3, an embodiment provided by the present utility model: a waterproof component for an instrument valve, including a first housing 4. A threaded rod 6 is rotatably connected inside the first housing 4. One end of the threaded rod 6 is fixedly connected to a valve 5. A slider 7 is threadedly connected to the outer wall of the threaded rod 6. One side of the outer wall of the slider 7 is rotatably connected to a first connecting rod 9. One side of the outer wall of the first connecting rod 9 is fixedly connected to a first fixing rod 10. One end of the first fixing rod 10 is fixedly connected to a bearing 11. A first rotating shaft 12 is fixedly connected inside the bearing 11. One end of the first rotating shaft 12 is fixedly connected to a second rotating shaft 13. A second connecting rod 14 is rotatably connected to the outer wall of the second rotating shaft 13. One end of the second connecting rod 14 is fixedly connected to a second fixing rod 29. A third connecting rod 15 is rotatably connected to the outer wall of the second rotating shaft 13. One end of the third connecting rod 15 is fixedly connected to the outer wall of the second fixing rod 29. A fixing frame 16 is fixedly connected to the outer wall of the second fixing rod 29. A sealing valve 17 is fixedly connected to one side of the outer wall of the fixing frame 16. An auxiliary component is rotatably connected inside the first housing 4 to assist the rotation of the threaded rod 6. The auxiliary component includes a connecting shaft 8. One end of the connecting shaft 8 is fixedly connected to the bottom of the threaded rod 6. The first housing 4 is fixedly connected to a third pipe 18.
[0026] Specifically, rotate the valve 6 to drive the threaded rod 7 to rotate, which drives the slider 8 to slide upward, causing the first connecting rod 10 to drive the first fixing rod 11 to rotate, making the bearing 12 and the first rotating shaft 13 rotate. Then, drive the second rotating shaft 14 through the first rotating shaft 13, thereby causing the second connecting rod 15 and the third connecting rod 16 to rotate. Next, when driving the second fixing rod 30, the fixing frame 17 causes the sealing valve 18 to move along the pipe, and the movement of the sealing valve 18 seals the third pipe 19 and the second pipe 4.
[0027] Refer to Figure 1 , Figure 4 and Figure 5 , one end of the third pipe 18 is fixedly connected to a first pipe 2. The other end of the third pipe 18 is fixedly connected to a second pipe 3. A backing plate 1 is fixedly connected to the lower surface of the third pipe 18. A support plate 19 is fixedly connected to the upper surface of the third pipe 18. A second rack 22 is fixedly connected to the upper surface of the support plate 19. The second rack 22 is meshed with a gear 23. One side of the outer wall of the gear 23 is fixedly connected to a fixing plate 21. The gear 23 is meshed with a first rack 20. One side of the outer wall of the first rack 20 is fixedly connected to a second housing 24. A connecting column 27 is fixedly connected to the upper surface of the support plate 19. One end of the connecting column 27 is fixedly connected to a dial 26. A fixing nut 28 is fixedly connected to the outer wall of the connecting column 27. A waterproof housing 25 is fixedly connected to the outer wall of the connecting column 27.
[0028] Specifically, first move the second housing 25 upward. Driving the first rack 21 inside the second housing 25 causes the gear 24 to move vertically along the edge direction of the second rack 23. Through the waterproof and leak-proof function of the second housing 25 on the outer wall of the instrument, a waterproof housing 26 is provided on the outer wall of the instrument panel 27 to achieve the waterproof effect on the instrument panel 26, avoiding being eroded by moisture in the air and completing the waterproof measure.
[0029] Working principle: When the device needs to be used, first rotate the valve 6 to drive the threaded rod 7 to rotate. Through the rotation of the threaded rod 7, the slider 8 slides upward along the threaded rod 7, so that the connecting rod 10 drives the fixed rod 11 to rotate, driving the bearing 12 and the rotating shaft 13 to rotate. Through the rotation of the rotating shaft 13, the rotating shaft 2 drives the connecting rod 15 and the connecting rod 16 to rotate, and then drives the fixed rod 30. When the fixed frame 17 drives the sealing valve 18 to move left and right, through the movement of the sealing valve 18, the pipeline 19 and the pipeline 2 are sealed, realizing the waterproof and leak-proof treatment inside the instrument valve, avoiding internal erosion due to water leakage. When it is necessary to observe the instrument data, first pull the outer shell 25 so that the outer shell 25 drives the internal rack 21 and the gear 24 to move along the direction of the rack 23. Through the outer shell 25, the waterproof and leak-proof of the instrument outer wall is realized. A waterproof shell 26 is installed outside the instrument panel 27 to protect the instrument panel 26, avoiding damage to the dial due to moisture in the air. Thus, the waterproof measures are completed.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
