Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: a water pressure resistance test tool, comprising: a pressure sealing tank 1, a front head 4, a hollow connecting screw 6 and a locking nut 9, wherein the pressure sealing tank 1 is a container for testing, by placing the sealing ring 3 on the annular step 2 and rotating the front head 4 to clamp the sealing ring 3; the front head 4 is a connecting piece connecting the hollow connecting screw 6 and the pressure sealing tank 1; the hollow connecting screw 6 connects the water pressure test pump and the pressure sealing tank 1, and the water source can be injected into the pressure sealing tank 1 through the hollow connecting screw 6; the locking nut 9 is used to lock the hollow connecting screw 6 and the front head 4.

[0026] The water pressure withstand test tooling with the above structure is implemented by inserting the hollow connecting screw 6 into the connecting through hole 5 in the front head 4, and embedding the annular protrusion 7 on the front head 4 into the countersunk hole 8, and then twisting the locking nut 9 to lock the front head 4 and the hollow connecting screw 6. Thereafter, the part to be tested is placed in the pressure sealing tank 1, and the sealing ring 3 is placed on the annular step 2 on the pressure sealing tank 1, and the front head 4 threadedly connected to the pressure sealing tank 1 is rotated to clamp the sealing ring 3, and then the water pressure test pump is connected through the hollow connecting screw 6, and finally the water pressure test pump is turned on to inject the pressure water source into the pressure sealing tank 1 for water pressure withstand test. The structure is simple to operate and can be quickly installed, which can improve the detection efficiency and solve the problem that the traditional water pressure withstand test tooling is complex to operate and difficult to install, resulting in low test efficiency.

[0027] In this embodiment, during use, the sealing ring 3 clamped between the pressure sealing tank 1 and the front head 4 is prone to leave a gap, affecting the test accuracy. By pressing the front head 4 and the pressure sealing tank 1 against each other, the sealing ring 3 can seal the pressure sealing tank 1 and the front head 4, thereby increasing the sealing performance and further increasing the test accuracy.

By providing the high-pressure hose bushing 11, it is convenient for the high-pressure hose bushing 11 to be connected to the hose of the water pressure test pump, thereby adapting to different models of water pressure test pumps.

[0031] In this embodiment, after the annular protrusion 7 and the countersunk hole 8 are pressed tightly, the high-pressure combined gasket 10 can seal between the annular protrusion 7 and the countersunk hole 8, and the high-pressure combined gasket 10 can seal between the annular protrusion 7 and the countersunk hole 8 after the annular protrusion 7 and the countersunk hole 8 are pressed tightly, thereby further improving the sealing performance.

[0032] Working principle: Insert the hollow connecting screw 6 into the connecting through hole 5 in the front head 4, and embed the annular protrusion 7 on the front head 4 into the countersunk hole 8, so that the annular protrusion 7 and the high-pressure combined gasket 10 are connected, and then twist the locking nut 9 to push the front head 4 upward, so that the annular protrusion 7 on the hollow connecting screw 6 and the countersunk hole 8 in the front head 4 are pressed against each other, and the high-pressure combined gasket 10 is clamped to seal and lock the hollow connecting screw 6 and the front head 4. Then put the part to be tested into the pressure sealing tank 1, and place the sealing ring 3 on the annular step 2 on the pressure sealing tank 1. , rotate the front head 4 threadedly connected to the pressure sealing tank 1 to clamp the sealing ring 3, so that the pressure sealing tank 1 and the front head 4 are sealed, and then the high-pressure hose bushing 11 threadedly connected to the hollow connecting screw 6 is threadedly connected to the hose of the water pressure test pump, and finally turn on the water pressure test pump to inject pressurized water into the pressure sealing tank 1 along the hollow connecting screw 6, so as to perform a water pressure withstand test. This structure is simple to operate and can be quickly installed, which can improve the detection efficiency and solve the problem that the traditional water pressure withstand test tooling is complicated to operate and difficult to install, resulting in low test efficiency.
