Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 to 2, the present embodiment provides a leak-proof high-pressure air pipe joint, which includes an air pipe connector 106 and an equipment connector; the equipment connecting piece comprises a first connecting head 103, an equipment pipeline main body 104 and a second connecting head 105;

the first connector 103 and the second connector 105 are respectively arranged at two ends of the equipment pipeline main body 104, two grooves are symmetrically arranged on the inner wall of the first connector 103, a telescopic clamping convex block 101 is respectively arranged in each groove, and the outer ring of the second connector 105 is provided with threads;

two clamping grooves are symmetrically formed in the outer wall of one end of the air pipe connecting piece 106, the air pipe connecting piece 106 is detachably connected to the first connecting head 103, and the clamping convex block 101 is clamped in the clamping grooves;

the outer diameter of the air pipe connecting piece 106 is not less than the inner diameter of the device pipeline main body 104, and the outer diameter of the air pipe connecting piece 106 is equal to the inner diameter of the first connecting head 103.

In this embodiment, a clamp spring 108 is disposed on an inner wall of the other end of the air pipe connector 106; further, the bottom of the clamp spring 108 is provided with a rubber ring 107. The clamp spring 108 and the rubber ring 107 can assist in clamping the high-pressure air pipe and avoid slipping.

In addition, a retractable snap-fit projection 101 is mounted in each of the grooves by a spring 102. In particular, the locking protrusion 101 may be a trapezoid, the bottom surface of which is used to connect the spring 102 for telescopic installation.

Finally, the end face of one end of the air pipe connector 106 and the end face of the equipment pipeline main body 104 close to the first connector 103 are respectively provided with a sealing rubber ring 201, and are in contact with each other.
