Problems solved by technology
[0004] However, in the technical solution described in this patent, the parts between the joint pipe and the gland are basically only fixed by the extrusion of the gland and the joint pipe. It is easy to drop, and after the pipe joint is used for a period of time, due to thermal expansion and contraction, the connection between the gland and the joint pipe will become loose, which will affect the transportation of the medium in the pipeline

The invention relates to a compressed air quick pipe connector. The pipe connector comprises a connector pipe and a gland. The connector pipe is sleeved with the gland, the gland is detachably connected with the connector pipe through threads, a clamping strip is fixedly arranged on the outer wall of the connector pipe and located at the inner end of the threads, and a circle of bayonets are arranged at the inner end of the gland at equal intervals. A clamping ring base is arranged at the end of the connector pipe, two sealing rings are arranged between the clamping ring base and the connector pipe, the inner rings of the sealing rings protrude out of the inner diameter of the clamping ring base, the outer end face of the clamping ring base is provided with an elastic clamping ring made of metal, the elastic clamping ring comprises a ring body and claw teeth, and the outer end of the elastic clamping ring abuts against a boss arranged on the gland; when the gland is screwed, the boss presses the elastic clamping ring to strut the claw teeth, and a pipe is bitten and is prevented from being disengaged. The compressed air quick pipe connector is simpler in structure and lower in production cost and improves pipe connection stability.
Description
technical field [0001] The invention relates to a quick pipe joint of a compressed air pipe. Background technique [0002] There are many kinds of pipe joints for connecting compressed air pipes. A common problem in existing pipe joints is that after the pipes are connected, the pipes and joints are not firmly connected, and axial displacement may occur between them. [0003] For this reason, the applicant has previously applied for a Chinese invention patent (patent number: 200810063105.6, invention name: compressed air quick pipe joint), which discloses a quick pipe joint that bites the pipe through claw teeth to prevent the axial displacement of the pipe. Joint, the joint includes a joint pipe and a gland, and a snap ring seat, an elastic snap ring and a pusher are sequentially installed between the joint pipe and the gland. The elastic snap ring includes a ring body and claw teeth. When in use, screw the gland tightly , so that the pusher and the snap ring seat squeeze...
