When selecting a pipe joint, it must have sufficient flow capacity and small pressure loss, and at the same time be easy to load and unload, have a firm connection, reliable sealing, and a compact appearance. There are many types of commonly used pipe joints, which can be divided into: flared type, welding type, ferrule type, crimping type, detachable type, quick-change type, and telescopic pipe joints according to the connection method between the oil pipe and the joint.

[0003] A kind of oil pipe quick connector disclosed in the Chinese utility model patent application publication specification CN205078967U includes a sleeve and a pipe connected to the rear part of the sleeve, and semicircular lugs are externally connected on the outer walls of both sides of the sleeve, and semicircular clamping blocks matching the internal cavity are hinged in the two lugs, and clamping holes for the clamping blocks to pass through and enter the sleeve are respectively opened at the positions corresponding to the two clamping blocks on the sleeve; a partition is provided in the sleeve, and a partition for placing the oil pipe interface is formed between the partition and the side wall of the sleeve, and each of the clamping blocks is connected to a handle, and the handle can be rotated to drive the clamping block to rotate so that it passes through the clamping hole and enters the interior of the partition and clamps the oil pipe interface in the partition or drives the clamping block to rotate and return to the interior of the lug. The utility model is quick and convenient to disassemble and assemble the oil pipe, does not need to disassemble and assemble screws, has no scattered parts, and the position of the clamping block to buckle the oil pipe is easy to align, and the buckle is tight.
