Abstract
An insert-type self-locking fast tube joint and a disassembling tool matched with same belong to the tube connecting and tube disassembling fields. The insert-type self-locking fast tube joint is characterized in that rubber sealing rings, a drum-shaped tube locking device with inner teeth and an inner supporting tube having outer wall with concave and convex stoppers are arranged in a tube joint shell, a dustproof guide plug bush is arranged at a throat of the tube joint, wherein the dustproof duct plug bush can be pulled out of the tube joint shell, injector blocks of the disassembling tool can be inserted into the tube joint shell to shove away the teeth of the tube locking devices so as to push a connected tube out; the bottom of the inner surface of the tube joint shell is fixedly integrated with the tail of the inner supporting tube, and the quantity of the inner supporting tube is determined according to materials of the connected tube. The disassembling tool matched with the insert-type self-locking fast tube joint comprises handles, the rigid ejector blocks, disassembling teeth and a shrinkage controlling switch. The problems of high requirements for labor, time and environmental condition of the jointing work and the non-reusability of the joint when the tube joint is used for connecting tubes of different materials are solved. By the aid of the tube joint with sealing and self-locking functions and the disassembling tool matched with the same, tubes can be assembled and dissembled in a fast and convenient way.
