Air pipe quick joint

Abstract

The invention discloses an air pipe quick joint. The air pipe quick joint comprises a joint body, wherein the joint body comprises a pipe head and a pipe tail, the joint body is integrally cast, raised safety barbs are arranged on the surface of the pipe head, clamping jaws are arranged on the pipe head in an axial symmetry mode, clamping grooves are formed in the clamping jaws, a convex sealing gasket is arranged in the pipe head, the convex sealing gasket is a natural rubber convex sealing gasket, the pipe tail is a fine corrugated pipe tail, and a smooth groove is formed in the tail end inlet of the pipe tail. According to the safety barb design, the locking effect is enhanced, and accidental loosening is avoided; the sealing gasket with the intelligent compensation function is arranged, so that the excellent sealing performance is achieved; the pipe tail is the fine corrugated pipe tail, so that the internal buckling force grabbing force is improved, and the whole stability and thesafety of the buckling-pressing are ensured; and the inlet is smooth, and the design of the groove is realized, so that the force path is saved when the joint enters a hose, and the flow of fluid islarger when the fluid passes through the hose.

Description

technical field [0001] The invention relates to the technical field of pipe fittings, in particular to an air pipe quick connector. Background technique [0002] The pipe joint is a connection tool between pipes and a detachable connection point between components and pipes. It plays an indispensable role in pipe fittings. It is one of the two main components of hydraulic pipes. The pipe joint is a detachable connecting element. It must meet the requirements of convenient disassembly and assembly in addition to the normal requirements of stable connection, strong sealing, reasonable size, small pressure loss, and good process performance. There are many kinds of pipe joints used to connect compressed air pipes. The traditional pipe joints need adapters when connecting with hoses, which are easy to loosen and cause falling off; traditional gaskets without compensation performance can only be used for positive pressure. It is easy to disengage each other and cause leakage und...
