[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a rubber seal airtightness tester, including a fixed box 1, a fixed plate 2 fixedly connected to the lower surface of the fixed box 1, a motor 3 fixedly connected inside the fixed box 1, a threaded rod 4 fixedly provided at the output end of the motor 3, the outer wall of the threaded rod 4 rotatably connected to the inside of the fixed plate 2, a connecting block 5 threadedly connected to the outer wall of the threaded rod 4, a sliding column 6 slidably connected inside the connecting block 5, the outer wall of the sliding column 6 fixedly connected to the inside of the fixed box 1, a spring 7 provided on the outer wall of the sliding column 6, one end of the spring 7 fixedly connected to the lower surface of the connecting block 5, the other end of the spring 7 fixedly connected to the upper surface of the fixed plate 2, a connecting rod 8 fixedly connected to the outer wall of the connecting block 5, a pressure plate 9 fixedly connected to the lower surface of the connecting rod 8, and a protective component provided on the outer wall of the fixed box 1;

[0024] Specifically, the fixing box 1 fixes the fixing plate 2 and the motor 3. Starting the motor 3 drives the threaded rod 4 to rotate inside the fixing plate 2. The fixing plate 2 supports the threaded rod 4, which in turn moves the connecting block 5. The connecting block 5 slides on the outer wall of the sliding column 6, which limits its movement. The connecting block 5 compresses the spring 7, which rebounds to maintain stable sliding of the connecting block 5 on the outer wall of the sliding column 6. The connecting block 5 also drives the connecting rod 8 to slide inside the fixing box 1, which limits its movement. The connecting rod 8 then compresses the pressure plate 9 to press the seal. By installing a pressure sensor inside the detector, the pressure on the seal can be detected, automatically determining its sealing performance and improving detection efficiency.

[0025] Reference Figure 1 The protective assembly includes a housing 10, the interior of which is fixedly connected to the outer wall of the fixed box 1, the interior of which is fixedly connected to the outer wall of the fixed plate 2, and a protective shell 11 fixedly connected to the interior of the housing 10.

[0026] Specifically, the housing 10 serves to fix the fixed box 1, the housing 10 is used to protect the internal components of the detector, the housing 10 serves to fix the fixed plate 2, the fixed plate 2 serves to support the internal components, the housing 10 serves to fix the protective shell 11, and the protective shell 11 serves to protect the aesthetics of the box.

[0027] Reference Figure 4 A fixing block 12 is fixedly connected to the upper surface of the housing 10, and an electric telescopic rod 13 is fixedly connected to the upper surface of the fixing block 12. A sliding block 14 is fixedly connected to the output end of the electric telescopic rod 13. A sliding plate 16 is fixedly connected to the outer wall of the sliding block 14. A limit post 15 is slidably connected inside the sliding plate 16. The outer wall of the limit post 15 is fixedly connected to the inside of the fixing box 1. A first rack 17 is fixedly connected to the outer wall of the sliding plate 16. A second sliding plate 18 is slidably connected to the outer wall of the first rack 17. A connecting plate 19 is fixedly connected to the upper surface of the sliding plate 18. The outer wall of the connecting plate 19 is slidably connected to the inside of the fixed plate 2. A clamping plate 20 is fixedly connected to the outer wall of the connecting plate 19. A second rack 22 is fixedly connected to the outer wall of the sliding plate 18. The outer wall of the second rack 22 is slidably connected to the inside of the sliding plate 16. A gear 21 is meshed with the tooth end of the second rack 22. The outer wall of the gear 21 is rotatably connected to the inside of the housing 10. The tooth end of the gear 21 is meshed with the tooth end of the first rack 17.

[0028] Specifically, the housing 10 fixes the fixing block 12, which in turn fixes the electric telescopic rod 13. Activating the electric telescopic rod 13 moves the sliding block 14, which in turn moves the sliding plate 16 against the outer wall of the limiting post 15. The limiting post 15 limits the sliding plate 16. The sliding plate 16 then moves the first rack 17 inside the second sliding plate 18, which limits the first rack 17. While moving, it can drive gear 21 to rotate inside the housing 10. Gear 21 can drive the second rack 22 to slide inside the sliding plate 16. The sliding plate 16 limits the second rack 22. The second rack 22 can drive the sliding plate 28 to slide. The sliding plate 16 and the sliding plate 28 can drive the connecting plate 19 to slide inside the fixing plate 2. The connecting plate 19 can drive the clamping plate 20 to clamp and fix the seal, preventing the seal from shifting during testing and affecting the testing effect.

[0029] Working principle: When the tester is needed, the rubber seal to be tested for air tightness is first placed from the protective shell 11 into the housing 10. By activating the electric telescopic rod 13, the sliding block 14 can be moved. While the sliding block 14 is moving, the sliding plate 16 can slide on the outer wall of the limiting post 15, which in turn drives the first rack 17 to slide inside the second sliding plate 18. At the same time, the gear 21 rotates inside the housing 10. While the gear 21 rotates, the second rack 22 can slide inside the first sliding plate 16, which in turn drives the second sliding plate 18 to slide on the outer wall of the limiting post 15. At the same time, the connecting plate 19 slides inside the fixing plate 2, which in turn drives the clamping plate 20 to clamp and fix the rubber seal, preventing displacement during the air tightness test and affecting the test results.

[0030] When testing rubber seals, starting motor 3 drives threaded rod 4 to rotate inside fixed box 1. Simultaneously, the rotation of threaded rod 4 causes connecting block 5 to slide on the outer wall of sliding column 6, compressing spring 7. As connecting block 5 slides, connecting rod 8 slides inside fixed box 1, thereby causing pressure plate 9 to compress the seal. A pressure sensor detects the pressure on the seal, analyzing its sealing performance to achieve automatic sealing detection and improve testing efficiency. This testing instrument not only clamps and fixes seals, improving accuracy, but also achieves automatic detection, further enhancing efficiency.

[0031] 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.
