Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to the attached drawings 1-2, an integrated quick connection joint for a composite pipe comprises a mandrel 1, wherein two ends of the mandrel 1 are both sleeved with buckling sleeves 2, one side, close to the mandrel 1, of each buckling sleeve 2 is provided with a conical structure 21, a buckling locking structure 3 is arranged between each buckling sleeve 2 and the mandrel 1, the mandrel 1 is limited in the conical structure 21 through the buckling locking structure 3, namely, the mandrel 1 is matched with the buckling locking structure 3, the outer diameter of the buckling locking structure 3 is smaller than the inner diameter of the minimum end of the conical structure 21, the buckling compression degree can be increased, the buckling failure caused by the fact that medium pressure in the pipe is too large is prevented, danger and environmental harm are caused, the buckling sleeves 2 are buckled with the mandrel 1 through the buckling locking structures 3, buckling can be locked through the buckling locking structures 3, and the buckling is released under the action of the external force, the buckling effect is influenced, and the buckling guarantee is improved.

Further in order to improve the buckling and locking mode, the buckling and locking structure 3 comprises a locking groove 31 formed in the outer wall of the mandrel 1 and locking teeth 32 formed in the inner wall of the buckling and pressing sleeve 2, when buckling is performed, the composite pipe is arranged between the mandrel 1 and the buckling and pressing sleeve 2 and is pre-sleeved on the buckling and pressing sleeve 2, the buckling and pressing sleeve 2 is pulled towards the direction opposite to the mandrel 1 through a tool, the composite pipe is clamped in the locking groove 31 and the locking teeth 32 of the section 21 of the conical structure, the buckling and pressing operation is performed on the buckling and pressing sleeve 2 through a buckling and pressing machine, the buckling and pressing sleeve 2 is tensioned outwards continuously while buckling and pressing, so that the buckling and pressing density is further improved, after the buckling and pressing is completed, the composite pipe is extruded into the locking groove 31 and between the adjacent locking teeth 32, the composite pipe is extruded and locked with the mandrel 1 and the buckling and pressing sleeve 2, and the buckling tightness is improved.
