Pipe connector

Abstract

A tube union comprises an adapter body (1) opened with a through hole (2). The middle of the through hole is provided with a locating step used for locating a connected pipe (12). The inner wall of the through hole is opened with a cushion rubber socket (5) and provided with an O-ring seal (6). Two ports of the through hole are pipe sockets (3) which are internally provided with an elastic locking gear ring (7) taking the shape of a ring. The inner edge of the ring body is provided with at least two latches which blends inward in the same direction and extends out. And the outer edge of the ring body is evenly distributed with fixed teeth which bends outward in the same direction and extends out; the stretching direction of the fixed teeth runs counter to an infolding latch. The hole wallat the most external end of the pipe sockets is provided with a bulge loop (4) and at least two projections; or the hole wall at the most external end of the pipe sockets is opened with a locating groove (14); the inflexed latch extends out and is blocked in the socket of the connected pipe and prevent the connected pipe from withdrawing from the tube union. The tube union has few fittings, simple structure and low cost and can be quickly arranged and dismantled by a special tool which is separately designed and independent of tube unions.

Description

technical field [0001] The invention relates to a pipe joint, in particular to a quick pipe joint. Background technique [0002] Traditional metal pipe connections are mainly threaded or welded. Threaded connections must be threaded on the pipe wall, which causes 40% of the material waste of the pipe wall thickness and weakens the strength of the pipe. Welding requires that the pipe has sufficient wall thickness. [0003] With the development of technology, the connection method of using internal tooth locking ring instead of thread to lock the pipe has appeared on the market, but the structure of the existing series of push-fit connection pipe fittings is too complicated, resulting in high manufacturing costs, so it has been difficult to use in the world promotion within the scope. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a pipe joint with few parts, simple a...
