[0026] Specifically, by moving the lever on the drive block 14, the drive block 14 rotates on the inner wall of the outer casing 1. The rotation of the drive block 14 drives the connecting column 13 to move, so that the slider 12 slides stably on the outer wall of the slide rail 11. The movement of the connecting column 13 drives the locking block 15 to slide, thereby clamping the sealing ring 16. By releasing the sealing ring 16, the sealing ring 16 can be quickly replaced. The outer casing 1 is removed from the top of the upper valve body 23. When the sealing ring 16 is released, it can be removed and replaced. By quickly installing the sealing ring 16, the bearing block 21 provides space for the ball inside the rotating rod 2 to rotate. When the sealing ring 22 needs to be replaced, the upper valve body 23 and the lower valve body 24 are quickly disassembled and assembled, thereby achieving the effect of quickly replacing the sealing ring 22.

[0027] Reference Figure 1 and Figure 3 The inner wall of the outer frame 3 is threaded with a threaded rod 31. A push block 32 is provided on the upper surface of the threaded rod 31. A connecting rod 33 is slidably connected to the inner wall of the push block 32. A connecting block 34 is slidably connected to the outer wall of the connecting rod 33.

A base 4 is slidably connected to the outer wall of the push rod 35. The rear outer wall of the base 4 is fixedly connected to the front outer wall of the lower valve body 24. A limit block 41 is fixedly connected to the upper surface of the base 4.

[0028] Specifically, rotating the threaded rod 31 pushes the push block 32 to move, causing the connecting rod 33 to move. The movement of the connecting rod 33 drives the connecting block 34 to move and rotate, thereby pushing the push rod 35 to slide on the inner wall of the outer frame 3. The movement of the push rod 35 can push the push block 42 to slide on the inner wall of the base 4, thereby achieving the effect of locking the connecting shell 47 and providing power.

[0029] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the limiting block 41 is slidably connected to the pushing block 42, the outer wall of the pushing block 42 is slidably connected to the inner wall of the base 4, the outer wall of the pushing block 42 is slidably connected to the outer wall of the push rod 35, the upper surface of the pushing block 42 is provided with a spring 43, the outer wall of the spring 43 is provided with a fixing block 44, and the outer wall of the fixing block 44 is fixedly connected to the inner wall of the limiting block 41; the inner wall of the limiting block 41 is fixedly connected to the rotating shaft 45, the outer wall of the rotating shaft 45 is rotatably connected to the pressing block 46, and the outer wall of the pressing block 46 is slidably connected to the inner wall of the pushing block 42; the outer wall of the pressing block 46 is slidably connected to the connecting shell 47, the lower surface of the connecting shell 47 is slidably connected to the upper surface of the base 4, and the inner wall of the connecting shell 47 is slidably connected to the outer wall of the limiting block 41;

[0030] Specifically, push rod 35 can push push block 42 to slide on the inner wall of limit block 41, so that spring 43 is compressed. By setting fixed block 44, the movement of spring 43 can be prevented from shifting. The movement of push block 42 can push lower pressure block 46 to rotate on the outer wall of rotating shaft 45, thereby locking connecting shell 47. Through the connection of base 4 and connecting shell 47, the upper valve body 23 and lower valve body 24 can be quickly connected.

[0031] Working principle: When this component is needed, the outer casing 1 is removed, and the lever on the drive block 14 is turned to rotate the drive block 14. The drive block 14 drives the connecting column 13 to move, causing the slider 12 to slide on the outer wall of the slide rail 11. At the same time, the locking block 15 on the lower surface of the connecting column 13 can move synchronously, thereby releasing the sealing ring 16 and achieving the effect of quickly removing the sealing ring 16. When it is necessary to remove the sealing ring 22, the threaded rod 31 is rotated to move the push block 32. The movement of the push block 32 can drive the connecting rod 33 to move simultaneously. The movement of the connecting rod 33 will drive the connecting block 34 to move the push rod 35 simultaneously. The push rod 35 moves on the inner wall of the base 4, which can push the push block 42 to slide in the inner wall of the limit block 41. The movement of the push block 42... The kinetic energy causes the spring 43 to undergo elastic deformation. The fixing block 44 set on the inner wall of the limiting block 41 can achieve the effect of limiting the movement trajectory of the spring 43. While pushing the block 42 to move, it will drive the lower pressure block 46 to rotate on the outer wall of the rotating shaft 45. When the connecting shell 47 is fitted on the outer wall of the limiting block 41, it can be fixed by the lower pressure block 46, thereby achieving the effect of quickly connecting the upper valve body 23 and the lower valve body 24. The bearing block 21 set on the inner wall of the upper valve body 23 and the lower valve body 24 serves as the bearing place of the ball valve ball. By rotating the rotating rod 2 to rotate the ball, the closing and opening are achieved. This component can achieve the effect of quickly replacing the sealing ring 16 on the one hand, and can also achieve the effect of quickly replacing the sealing ring 22 by quickly disassembling and assembling the upper valve body 23 and the lower valve body 24 on the other hand.
