DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the hydraulic pipe fitting with convenient disassembly and stable connection comprises a pipeline 1 and a pipe joint, wherein the pipe joint comprises a connecting head 2 and a receiving head 3, an annular groove 4 is provided on the connecting head 2, a plurality of axially movable buckles 5 are provided on the side wall of the annular groove 4, a spring 6 is provided between the buckle 5 and the bottom of the annular groove 4, a hanging ring 7 is provided at the bottom of the front end of the buckle 5, a linear component 8 for pulling the buckle 5 is connected to the hanging ring 7, and the linear component 8 passes through the annular groove 4 and extends inward to the pipeline 1 of the connecting head 2;

[0018] An annular sliding component 9 is provided on the pipe 1 at the connector 2, and a cavity 10 for the sliding component 9 to slide is provided on the pipe 1. A covering portion 11 abutting against the pipe 1 is provided at one end of the sliding component 9, and a groove 12 is provided at one end. A protrusion 13 extending to the inside of the cavity 10 is provided at the lower end of the groove 12, and a spring 6 is provided in the cavity 10;

[0019] A buckle 2 14 for matching with buckle 1 5 is arranged on the inner wall of the receiving head 3 , and a fitting portion 15 which fits the connecting head 2 and has an elastic reset function is arranged inside the receiving head 3 , and a sealing rubber 16 is arranged on the fitting portion 15 .
