Abstract

The invention relates to a fast tube joint of a compressed air pipe, which comprises a joint pipe and a gland bush; the joint pipe and the gland bush are connected detachably by screw threads, and the end part of the joint pipe is provided with a snap ring base; the inner end of the snap ring base is inserted into the interior of the joint pipe and provided with a sealing ring, and pushes against the snap ring base; the inner ring of the sealing ring protrudes through the inside diameter of the snap ring base; the outer end face of the snap ring base is provided with an elastic snap ring which is made of metal and comprises a ring body and claw teeth, and the claw teeth are flanged to the direction of the snap ring base and arranged on an inclined ring which is arranged on the opening of the snap ring base; the outer end of the elastic snap ring is provided with a push part, and two ends of the push parts respectively pushes against the elastic snap ring and a convex platform. When the fast tube jonit is used, the gland bush is screwed tightly, the convex platform on the gland bush oppresses the push part, and the push part oppresses the elastic snap ring to lead the claw teeth to be propped; therefore, the claw teeth can grip the pipe to prevent the pipe from escaping. The fast tube joint is characterized by simple structure, convenient implementation and firm connection.

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] To this end, Chinese invention patent CN1200795 discloses a device for connecting a pipe to a cylindrical joint piece consisting of a front surface and a connecting sleeve whose first section includes a A detachable retaining device that engages the alignment device on the sleeve, while the second segment axially adjoining the first segment includes features for preventing the end of the tube inserted into the sleeve from slipping out and engaging the front surface of the fitting. device. the sleeve has a built-in guide collar for guiding the end of the tube, the guide collar having an inner diameter...
