Abstract
A quick connecting pipe joint structure is composed of a joint base, a locking threaded sleeve, an inner sleeve and a sealing ring. The front end of the joint base is provided with a pipe-shaped member. The outer periphery of the pipe-shaped member is separately provided with circumferential flanges. The inner sleeve is sleeved outside the pipe-shaped member. The inner wall of the inner sleeve is provided with circumferential flanges. A clearance is provided between the inner circumferential wall of the inner sleeve and the outer periphery of the pipe-shaped member. The front end of the outer wall of inner sleeve is provided with a conical surface. The inner wall of the locking threaded sleeve is provided with a conical surface. The back end of the locking threaded sleeve is connected with the joint base. A clearance is provided between the inner wall of the front outlet of the locking threaded sleeve and the front outer periphery of the pipe-shaped member. After a connecting pipe is inserted and connected, the locking threaded sleeve compresses the connection pipe between the inner sleeve and the pipe-shaped member of the joint base for performing an anti-falling function. The circumferential flanges at the inside of the inner sleeve and the outside of pipe-shaped member can realize reliable sealing and connection while a smaller pressure is exerted to the locking threaded sleeve. The strength requirement to the component is reduced. A screwing tool can be saved and fast connection is facilitated.
