Example 1

As shown in Figure 2, a hydraulic pipe joint with adjustable length function, including

Main body 1, the inside of the main body 1 is set as a hollow tubular structure; the inside of the main body 1 is provided with a sliding groove 11; the length of the sliding groove 11 is set to half the length of the main body, and is located middle part.

Pipe body joints 2, two pipe body joints 2 are provided, which are respectively slidably arranged inside the main body 1; specifically, the two pipe body joints 2 are respectively plugged into the two ends of the main body 1; The pipe body joint 2 is composed of a smooth pipe body 21 and a threaded pipe body 22 from the inside to the outside. Specifically, the length ratio of the smooth pipe body 21 and the threaded pipe body 22 is 2:1; The smooth section pipe body 21 is located in the sliding groove 11 and slides along the sliding groove 11;

The threaded pipe body 22 is used for installation with the hydraulic pipe, and the structure of the threaded pipe body 22 is the same as that of the outer wall of the existing connector. In order to enable the hydraulic pipe to be stably socketed on the pipe body joint 2, the front end of the pipe body joint 2 is arranged in an arc-shaped structure.
