Abstract

The invention discloses a fuel oil pipeline joint. The fuel oil pipeline joint comprises a male joint and a female joint, and further comprises a lock catch for mounting the male joint onto the male joint, wherein the male joint is of a hollow structure which is through from top to bottom; the male joint comprises a male joint connecting tube, a first hose connecting part, an outer retainer ring and an inner blocking ring; the female joint is of a hollow structure which is through from top to bottom; the female joint comprises an opening structure, a female joint connecting tube and a second hose connecting part; lock catch mounting holes which are through from left to right are separately formed in the left side and the right side of the opening structure; buckling slots are separately formed in the front side wall and the rear side wall of the opening structure; buckling slots are separately formed in the left end and the right end of each side wall; the circular opening communicates with the lock catch mounting holes and the buckling slots; the lock catch comprises a U-shaped lock catch body which is horizontally arranged, an upper step part and a lower step part; and the opening of the U-shaped lock catch body is arranged towards the lock catch mounting holes. The invention provides the fuel oil pipeline joint which is simple in structure, is convenient to manufacture and is convenient to dismount.

Description

technical field [0001] The invention belongs to the field of pipeline connection, in particular to a fuel pipeline joint. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools; it is mainly used for quick installation of gas and liquid pipelines. [0003] Existing quick joints are all realized by two clamping positions. Although they are easy to install and disassemble, their reliability is not high; there are also some multi-jaw joints at present, but they are easy to install and not easy to disassemble. Contents of the invention [0004] In order to overcome the disadvantage that existing quick joints are not easy to be disassembled, the present invention provides a fuel line joint with simple structure, convenient manufacture and easy disassembly. [0005] The technical solution adopted by the present invention to solve its technical problems is: [0006] A fuel line joint, including a male joint and a femal...
