In order to facilitate the subsequent smooth movement, the inside of the connecting column 6 is provided with two movable holes 8, and the inside of the connecting column 6 is provided with two engaging holes 9.

[0025] Reference Figure 2 - Figure 4 , the interior of the connecting column 6 is slidably connected with a plurality of limit plates 10, the top of the limit plate 10 is fixedly connected with a ejection block 11, the bottom end of the limit plate 10 is fixedly connected with a force rod 12, and the outside of the force rod 12 is sleeved with a strong spring 13. This design can provide a rebound force through the strong spring 13 when the force rod 12 is under pressure, thereby maintaining the stability and reusability of the structure. One end of the strong spring 13 is fixedly connected to the bottom end of the limit plate 10, and the other end of the strong spring 13 is fixedly connected to one side of the interior of the connecting column 6. A plurality of circular holes 14 are opened inside the bottom end of the connecting column 6, and the outside of the force rod 12 is slidably connected to the inside of the circular hole 14. This design not only ensures the stability of the force rod 12, but also It is allowed to move freely within a certain range. The inside of the connecting column 6 is slidably connected to a pressure gauge 15. The outside of the pressure gauge 15 is rotatably connected to two sealing blocks 16 to ensure the stability of the pressure gauge 15 in the device and prevent leakage during the test. The outside of the sealing block 16 is slidably connected to the inside of the sliding hole 7. The outside bottom end of the pressure gauge 15 is fixedly connected to two snap blocks 17. The outside of the snap block 17 is slidably connected to the inside of the sliding hole 7. The outside of the snap block 17 is slidably connected to the inside of the movable hole 8.

The snap block 17 and the snap hole 9 are engaged and unlocked by pressing the pressure gauge 15.

[0026] Reference Figure 1 and Figure 5 The left side of the top of the pipe 1 is fixedly connected with a connecting assembly of the connecting device, and the connecting assembly includes a connecting block 18. The connecting block 18 has a built-in thread and can also be installed on various equipment to test water tightness. A valve 2 19 is arranged on the outside of the connecting block 18. The bottom end of the connecting block 18 is fixedly connected to the left side of the top of the pipe 1. The middle part of the bottom end of the pipe 1 is fixedly connected with a connecting block 20. The inside of the connecting block 20 is fixedly connected with two fixed blocks 21. The inner wall of the fixed block 21 is slidably connected with a sliding rod 22. The fixed block A chamber 23 is provided inside 21, and a strong spring 24 is sleeved outside the sliding rod 22. This design can provide necessary resistance and resilience when the sliding rod 22 moves. A baffle 25 is fixedly connected to the outside of the sliding rod 22, and baffles 26 are fixedly connected to the far sides of the two sliding rods 22. Clamping blocks 27 are fixedly connected to the adjacent sides of the two sliding rods 22 to ensure that the clamping blocks 27 can firmly clamp the tested equipment or pipeline. These clamping blocks 27 are used to directly clamp and fix the tested pipeline or equipment.

[0027] Working principle: when the old pressure gauge 15 needs to be replaced, first press the pressure gauge 15, and the pressing of the pressure gauge 15 drives the locking block 17 to slide out from the inside of the locking hole 9, and then the locking block 17 contacts the ejection block 11, and then the ejection block 11 drives the limit plate 10 to slide inside the connecting column 6, which will drive the force-bearing rod 12 to slide into the inside of the circular hole 14, and the strong spring 13 will also be stressed in this process. After the strong spring 13 is stressed, it will generate a rebound force, and this rebound force provides the subsequent locking block 17 to be engaged to ensure the stability of the pressure gauge 15. Then, in this process, the locking block 17 will be moved to the inside of the movable hole 8. At this time, it is rotated half a circle to make the locking block 17 slide inside the movable hole 8 and slide to the sliding hole 7. At this time, the pressure gauge 15 can be taken out by pulling it. After installation, the sealing block 16 provides additional sealing, and the sealing block 16 and the pressure gauge 15 are connected in rotation. When the tested water pipe needs to be connected, the baffle 26 is pulled at this time, and the sliding rod 22 is driven to slide inside the fixed block 21 under the pull of the baffle 26, and then the clamping block 27 is driven to move under the movement of the sliding rod 22. In this process, the baffle 25 is also driven to slide inside the chamber 23, and then the strong spring 24 is driven to be stressed. At this time, the water pipe is installed inside the connection block 20, and the baffle 26 is loosened, which will make the force on the strong spring 24 disappear, which will produce a certain rebound force. This rebound force is to provide the force for connecting with the water pipe. The pipe plug is fixed on the top of the pipe, and the lower end is sealed with different sealing materials and sealing systems. The sealing effect is tested by pressing. The upper end of the device has built-in threads and can also be installed on various equipment to test water tightness.
