[0025] The adjusting assembly 4 includes a mounting bracket 41. The mounting bracket 41 is mounted on the side of the pump body 5. A connecting nut 43 is welded to the middle of the upper end of the mounting bracket 41. A screw 44 is rotatably connected to the middle of the connecting nut 43. An adjusting disc 42 is connected to the top of the screw 44. A rotating shaft seat 45 is connected between the lower end of the screw 44 and the plunger of the pump body 5.

[0026] Specifically, the screw 44 is threadedly connected to the connecting nut 43, and the bottom of the mounting bracket 41 is welded and fixed to the pump chamber 3.

[0027] By adopting the above technical solution, the screw 44 is ensured to rotate in the connecting nut 43, so that the screw 44 drives the plunger of the pump body 5 to move.

[0028] Specifically, the bottom of the screw 44 is rotatably connected to the rotating shaft seat 45, and the rotating shaft seat 45 is welded and fixed to the plunger of the pump body 5.

[0029] By adopting the above technical solution, the screw 44 drives the plunger of the pump body 5 to move through the rotating shaft seat 45. The pump body 5 draws water from the water tank 1 through the water inlet 2 and transports it through the delivery pipe 7, so that the device in the sealed chamber 10 can be subjected to a water pressure test. The water pressure is regulated stably to ensure the accuracy of the water pressure test.

[0030] Specifically, the adjustment disc 42 includes a fixing block 424, the top of the rotating shaft seat 45 is fixedly connected to the fixing block 424, the fixing block 424 is welded around the fixing block 424, the side of the support rod 421 is connected to the turntable 422, and the upper end of the support rod 421 is fixedly connected to the rotating handle 423.

[0031] By adopting the above technical solution, rotating the turntable 422 or rotating the handle 423 causes the support rod 421 to drive the fixed block 424 to rotate, and the screw 44 at the lower end of the fixed block 424 rotates in the connecting nut 43.

[0032] In this embodiment, the device requiring a water pressure test is placed in the sealed chamber 10. The upper cover 9 of the sealed chamber is sealed and fixed to the sealed chamber 10 with bolts. Rotating the turntable 422 or rotating the handle 423 causes the support rod 421 to drive the fixing block 424 to rotate. The screw 44 at the lower end of the fixing block 424 rotates in the connecting nut 43, causing the screw 44 to drive the plunger of the pump body 5 to move. The pump body 5 draws water from the water tank 1 through the suction port 2 and transports it through the delivery pipe 7, so that the device in the sealed chamber 10 can undergo a water pressure test. The water pressure is regulated stably to ensure the accuracy of the water pressure test.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that: the lifting assembly 8 includes a frame 85, the side of the sealed chamber 10 is bolted to the frame 85, the upper side of the frame 85 is fixed to a support plate 84, the two ends of the support plate 84 are movably connected to lifting rods 81, the bottom of the lifting rods 81 is fixed to the upper cover 9 of the sealed chamber, the top of the lifting rods 81 is fixed to a limit block 83, and a return spring 82 is nested on the surface of the lifting rods 81 located between the support plate 84 and the limit block 83.

[0035] By adopting the above technical solution, the bolts connecting the upper cover 9 of the sealing chamber to the sealing chamber body 10 are unscrewed. The elastic force of the return spring 82 pushes the lifting rod 81 to move upward in the support plate 84. The upward movement of the lifting rod 81 causes the upper cover 9 of the sealing chamber to move upward, so that the upper cover 9 of the sealing chamber can be quickly separated from the sealing chamber body 10, reducing the trouble of manual lifting, saving time and effort, and making it convenient to use.

[0036] Specifically, when the sealed chamber cover 9 is connected to the sealed chamber body 10, the return spring 82 is in a compressed state, and the top of the return spring 82 is fastened and fixed to the limit block 83.

[0037] By adopting the above technical solution, the elastic force of the reset spring 82 is guaranteed to push the lifting rod 81 to move upward in the support plate 84. The upward movement of the lifting rod 81 causes the upper cover 9 of the sealing chamber to move upward, so that the upper cover 9 of the sealing chamber is quickly separated from the sealing chamber body 10.

[0038] Specifically, the sides of the limiting block 83, the reset spring 82, and the lifting rod 81 do not contact the conveying pipe 7.

[0039] By adopting the above technical solution, the elastic force of the reset spring 82 is guaranteed to push the lifting rod 81 to move upward in the support plate 84, thus avoiding obstruction.

[0040] In this embodiment, when the bolts connecting the upper cover 9 of the sealing chamber to the sealing chamber body 10 are unscrewed, the elastic force of the return spring 82 pushes the lifting rod 81 to move upward in the support plate 84. The upward movement of the lifting rod 81 causes the upper cover 9 of the sealing chamber to move upward, so that the upper cover 9 of the sealing chamber is quickly separated from the sealing chamber body 10, reducing the trouble of manual lifting, saving time and effort, and making it convenient to use.

[0041] The working principle and usage process of this utility model are as follows: When using this utility model, the device requiring a water pressure test is placed in the sealed chamber 10. The upper cover 9 of the sealed chamber is sealed and fixed to the sealed chamber 10 with bolts. Rotating the turntable 422 or rotating the handle 423 causes the support rod 421 to drive the fixing block 424 to rotate. The screw 44 at the lower end of the fixing block 424 rotates in the connecting nut 43, causing the screw 44 to drive the plunger of the pump body 5 to move. The pump body 5 draws water from the water tank 1 through the suction port 2 and transports it through the delivery pipe 7, so that the device in the sealed chamber 10 can undergo a water pressure test. The water pressure is regulated stably to ensure the accuracy of the water pressure test. Unscrewing the bolts connecting the upper cover 9 of the sealed chamber to the sealed chamber 10 causes the spring force of the return spring 82 to push the lifting rod 81 to move upward in the support plate 84. The upward movement of the lifting rod 81 causes the upper cover 9 of the sealed chamber to move upward, so that the upper cover 9 of the sealed chamber can quickly separate from the sealed chamber 10, reducing the trouble of manual lifting, saving time and effort, and making it convenient to use.
