Description

Technical Field

[0002] After searching, application number 202322355637.X discloses a hydraulic hose assembly pressure testing device, including a box for pressure testing of the hydraulic hose assembly and a support leg for supporting the box. The top of the box is screwed connected to a motor for rotational drive. The output shaft of the motor passes through the top of the box and is connected to one end of a reverse double-threaded rod. The other end of the reverse double-threaded rod is rotatably connected to the inner bottom wall of the box. The reverse double-threaded rod is threadedly connected to two movable plates for connecting when the hydraulic hose is subjected to pressure testing. A plurality of through holes are provided on the top of the movable plate.

[0003] During use, a hydraulic hose assembly pressure test device in this patent application completes the connection and fixation between hoses of different sizes and the test end by designing a movably connected clamp in the through hole, which can change the size according to the size of the hydraulic hose. However, during such use, since the clamp is movably installed inside the through hole, the hydraulic hose fixed by the clamp is also movably set inside the through hole. This installation method has poor stability and affects the pressure test of the hydraulic hose. For this reason, we propose a hydraulic hose pressure test device. Utility Model Content
