[0022] Specifically, the inner wall of the first joint 10 is provided with internal threads, and the outer wall of the second joint 20 is provided with external threads. The second joint 20 is inserted into the first joint 10 and is screwed with the first joint 10 through the cooperation of the external threads and the internal threads.

[0023] Specifically, the first joint 10 is internally provided with a first mounting hole 11, and the second joint 20 is internally provided with a second mounting hole 21. The first mounting hole 11 is an axial stepped hole provided in the first joint 10, and the second mounting hole 21 is an axial through hole provided in the second joint 20.

The second flange 41 is located outside the second mounting hole 21 and can abut against the end surface of the second joint 20 close to the first joint 10. The diameter of the small hole section 112 of the first mounting hole 11 is comparable to the outer diameter of the first connecting pipe 30, so that the first connecting pipe 30 can axially move relative to the first joint 10 and has good cooperation and sealing with the first joint 10. The diameter of the second mounting hole 21 is comparable to the diameter of the second connecting pipe 40, so that the second connecting pipe 40 can axially move relative to the second joint 20 and has good cooperation and sealing with the second joint 20. During the screwing of the first joint 10 and the second joint 20, the second connecting pipe 40 and the first connecting pipe 30 are brought close to each other, so that the first flange 31, the second flange 41 and the gasket 50 are pressed against each other to form a sealed connection.
[0025] Further, the first flange 31 extends outwardly from the port of the first connecting pipe 30 in a direction perpendicular to the first connecting pipe 30, and the second flange 41 extends outwardly from the port of the second connecting pipe 40 in a direction perpendicular to the second connecting pipe 40, so that the first flange 31 and the second flange 41 form flat plate circular ring shapes at the ports of the first connecting pipe 30 and the second connecting pipe 40, that is, the ports of the first connecting pipe 30 and the second connecting pipe 40 are formed into flat openings. Compared with the various types of flared forms in the prior art, the processing difficulty of the brake pipe is reduced, the types of flaring are reduced, and universalization is achieved.

[0027] Please refer to Figure 3 , the inside of the second connecting pipe 40 is hollow, the inside of the first connecting pipe 30 is hollow, the middle of the gasket 50 is provided with a through hole 51, the axis of the second connecting pipe 40, the axis of the first connecting pipe 30, and the axis of the through hole 51 are on the same straight line, so that the oil can flow between the second connecting pipe 40, the first connecting pipe 30 and the through hole 51.
[0028] Further, the outer diameter of the gasket 50 is greater than the outer diameter of the first flange 31 and the second flange 41, and the elasticity of the gasket 50 is greater than the elasticity of the first flange 31 and the second flange 41, so that the gasket 50 can withstand the extrusion of the first flange 31 and the second flange 41 to form a sealed connection. The outer diameter of the gasket 50 is comparable to the inner diameter of the first large hole section 111, which further improves the sealing between the first flange 31 and the second flange 41, so that the oil in the first connecting pipe 30 and the second connecting pipe 40 will not overflow between the first flange 31 and the second flange 41.
[0029] It should be noted that the elasticity in the utility model refers to the ability of an object to deform elastically. In the utility model, the gasket 50 can be a rubber gasket, a copper gasket, etc., as long as it is more likely to deform than the first flange 31 and the second flange 41. The rubber gasket is more likely to deform when extruded, forming a sealed connection. Copper is relatively soft and more likely to deform when extruded than steel, so the copper gasket can deform slightly when extruded by the steel first connecting pipe 30 and the second connecting pipe 40, filling the gap between the copper gasket and the first flange 31 and the second flange 41, and forming a sealed connection.
[0030] From the above description, it can be known that the pipe connecting structure provided by the utility model, through setting corresponding first flanging 31 and second flanging 41 at the end of first connecting pipe 30 and second connecting pipe 40, the end of first connecting pipe 30 and second connecting pipe 40 is in the form of flat mouth, compared with the flaring form of multiple angles in the prior art, the machining difficulty of the brake pipe can be reduced, the types of flaring are reduced, and universalization is realized; and through increasing gasket 50 between first flanging 31 and second flanging 41, the ports of first connecting pipe 30 and second connecting pipe 30 do not directly contact, so that even if the port surface is slightly scratched in the machining process, the gasket 50 can be closely attached, the risk of oil leakage is reduced, in addition, in the prior art, the trumpet mouth and the mushroom head in the flaring are both rigid structures, after one-time disassembly, the contact surface is easy to produce indentation, and oil leakage is easy to occur during secondary assembly, the cooperation of the port in the form of flat mouth and gasket 50 can avoid the risk of oil leakage caused by indentation, the elasticity of gasket 50 is stronger than that of first flanging 31 and second flanging 41, and indentation is not easy to be left on the surface of gasket 50 after first assembly, so that secondary assembly can also be perfectly sealed, and the after-sales disassembly is facilitated.
