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.

[0022] Reference Figure 1 - Figure 2 An embodiment of this utility model provides a quick-release valve pressure balancing auxiliary device, including a support plate 1, a block 2 fixedly connected to the upper surface of the support plate 1, a cylinder 3 fixedly connected to the upper surface of the block 2, a sealing ring 4 fixedly connected to the output end of the cylinder 3, a storage cylinder 5 slidably connected to the outer wall of the sealing ring 4, a block 6 fixedly connected to the outer wall of the storage cylinder 5, the lower surface of the block 6 fixedly connected to the upper surface of the support plate 1, a connecting pipe 7 fixedly connected to the inside of the storage cylinder 5, a cylinder 8 fixedly connected to the outer wall of the connecting pipe 7, the outer wall of the cylinder 8 fixedly connected to the upper surface of the support plate 1, a three-way pipe 9 rotatably connected to the inside of the cylinder 8, the outer wall of the three-way pipe 9 slidably connected to the outer wall of the connecting pipe 7, a connecting pipe 10 slidably connected to the outer wall of the three-way pipe 9, and a connecting pipe 11 slidably connected to the outer wall of the three-way pipe 9, the outer walls of the connecting pipe 10 and the connecting pipe 11 are both fixedly connected to the inside of the cylinder 8, and a driving assembly is provided on the upper surface of the support plate 1.

[0023] Specifically, the upright block 2 is fixed on the upper surface of the support plate 1 and has a fixing effect on the cylinder 3. The sealing ring 4 can slide through the cylinder 3. The storage tube 5 is fixed on the upper surface of the block 6 and has a supporting effect on the sealing ring 4. The sealing ring 4 has a sealing effect on the storage tube 5. The storage tube 5 and the cylinder 8 both have the function of fixing the connecting pipe 7. When the three-way pipe 9 is connected to the connecting pipe 7 and the connecting pipe 11, the pressure released inside the connecting pipe 11 can be extracted and stored inside the storage tube 5. When the three-way pipe 9 is connected to the connecting pipe 7 and the connecting pipe 10, the pressure inside the storage tube 5 can be released into the connecting pipe 10.

[0024] Reference Figure 2 The drive assembly includes a fixed plate 12, the lower surface of which is fixedly connected to the upper surface of the support plate 1. A fixed shaft 13 is rotatably connected inside the fixed plate 12. A connecting piece 14 is fixedly connected to the outer wall of the fixed shaft 13. A cylinder 15 is fixedly connected to the outer wall of the connecting piece 14. A connecting block 16 is fixedly connected to the output end of the cylinder 15. A rotating plate 17 is fixedly connected to the outer wall of the connecting block 16. A connecting rod 18 is fixedly connected inside the rotating plate 17. The outer wall of the connecting rod 18 is rotatably connected to the inside of the cylinder 8. The outer wall of the connecting rod 18 is fixedly connected to the outer wall of the three-way pipe 9.

[0025] Specifically, the fixing plate 12 is fixed on the upper surface of the support plate 1 and supports the fixing shaft 13. The fixing shaft 13 fixes the connecting piece 14, and the connecting piece 14 fixes the cylinder 15. The cylinder 15 allows the rotating plate 17 to rotate due to the sliding of the connecting block 16. The rotating plate 17 fixes the connecting rod 18, and the cylinder 8 supports the connecting rod 18. The connecting rod 18 fixes the three-way pipe 9, allowing the three-way pipe 9 to rotate through the rotation of the connecting rod 18. By adjusting the positional relationship between the three-way pipe 9 and the connecting pipe 7, connecting pipe 10, and connecting pipe 11, an adjustment circuit can be formed to effectively balance the pressure released by the quick-release valve.

[0026] Reference Figure 3 A base plate 19 is slidably connected to the lower surface of the support plate 1. A push rod 20 is slidably connected to the inside of the base plate 19. A fixing plate 21 is fixedly connected to the outer wall of the push rod 20. A push piece 22 is fixedly connected to the outer wall of the push rod 20. The outer wall of the push piece 22 is slidably connected to the inside of the base plate 19. A push block 23 is slidably connected to the outer wall of the push piece 22. The outer wall of the push block 23 is slidably connected to the inside of the base plate 19. A spring 24 is fixedly connected to the outer wall of the push block 23. A locking rod 25 is fixedly connected to the outer wall of the push block 23. The outer wall of the locking rod 25 is rotatably connected to the inside of the base plate 1. The outer wall of the locking rod 25 is rotatably connected to the inside of the support plate 1. A support shaft 26 is rotatably connected to the inside of the locking rod 25. The outer wall of the support shaft 26 is fixedly connected to the inside of the base plate 19.

[0027] Specifically, the base plate 19 supports the support plate 1 and the push rod 20. The push rod 20 fixes the fixing piece 21 and the push piece 22. The push piece 22 slides inside the base plate 19 due to the sliding of the push rod 20 and pushes the push block 23. The base plate 19 supports the push block 23. The spring 24 is compressed due to the sliding of the push block 23. The push block 23 also fixes the locking rod 25. The support shaft 26 is fixed inside the base plate 19 and supports the locking rod 25. The locking rod 25 rotates due to the sliding of the push block 23. When the locking rod 25 rotates into the slot opened inside the support plate 1, the spring 24 pushes the locking rod 25 into the support plate 1, thereby installing and using the support plate 1 and the base plate 19.

[0028] Working principle: When the balancing auxiliary device is needed, it is quickly installed and used. Pushing the fixing plate 21 causes the push rod 20 to slide inside the base plate 19. The sliding of the push rod 20 causes the push plate 22 to slide inside the base plate 19, and during the sliding process, it squeezes the push block 23. When the push block 23 is squeezed, it squeezes the spring 24. During the sliding process, the outer wall clamp 25 rotates inside the base plate 19 through the internal support shaft 26. At this time, the support plate 1 is placed on the upper surface of the base plate 19, and the fixing plate 21 is released. Fixed plate 21 and spring 24 will push the locking rod 25 to rotate through push block 23 by rebound. The support plate 1 has a slot inside, so that the locking rod 25 can be locked into the slot inside the support plate 1. The support plate 1 and base plate 19 are installed and used, so as to achieve quick installation and use of the device, which is convenient and saves installation time. When it is necessary to balance the pressure of the quick exhaust valve, one end of the connecting pipe 11 is connected to the quick exhaust valve. The cylinder 15 is started. The cylinder 15 will drive the connecting block 16 to slide. The sliding of the connecting block 16 will drive the rotating plate 1 on the outer wall. 7. Rotation of the rotating plate 17 causes the internal connecting rod 18 to rotate inside the cylinder 8, and also causes the three-way pipe 9 to rotate inside the cylinder 8. One end of the three-way pipe 9 is aligned with the connecting pipe 3 11, and the other end is aligned with the connecting pipe 1 7. The cylinder 1 3 on the upper surface of the upright block 2 is activated. The cylinder 1 3 causes the sealing ring 4 to slide inside the storage cylinder 5. During the sliding process, the sealing ring 4 extracts the pressure released inside the connecting pipe 3 11 through the connecting pipe 1 7 and the three-way pipe 9. The cylinder 2 15 is activated again to... One end of the three-way pipe 9 is aligned with the second connecting pipe 10, and the other end is still aligned with the first connecting pipe 7. Activating the first cylinder 3 can release the pressure drawn from inside the storage cylinder 5 through the three-way pipe 9 into the second connecting pipe 10, achieving the effect of balanced pressure release through the adjustment circuit. This avoids adverse consequences caused by instantaneous pressure changes. This device not only allows for quick installation and use, reducing installation time, but also ensures internal pressure balance through the adjustment circuit, preventing adverse consequences caused by instantaneous pressure changes.
