Problems solved by technology

[0006] At the other end of the joint, there is an external thread used to connect the pipe and the valve body, which is generally sealed with a raw material tape, which is labor-intensive, low in efficiency, easy to crack if it is too tight, and easy to leak if it is too loose, and requires high requirements for installers.

Abstract

The invention discloses a quickly assembled and disassembled convenient joint. The convenient joint comprises a joint (1), a locking screw cap (2), a movable pawl (3) and a pipe clamp (4); one end of the joint (1) is provided with a pipe body connecting port (5); the locking screw cap (2) is arranged outside the pipe body connecting port (5); the locking screw cap (2) is provided with a groove A (7) and a groove B (8); the movable pawl (3) is arranged in the groove B (8); the movable pawl (3) is provided with an annular skirt edge (11); an end cover (12) is arranged in the groove A (7); the skirt edge (11) is movably positioned in the groove B (8) by the end cover (12); and an O-shaped silica gel sealing ring B (15) is arranged at the other end of the joint (1). The convenient joint has the advantages that: because the movable pawl and the locking screw cap form an integrated structure, the convenient joint is convenient for installation, has a better sealing effect and does not affect the sealing quality when being repeatedly assembled and disassembled; and the locking screw cap is a double-purpose screw cap and is convenient for installation.

Description

technical field [0001] The invention relates to a pipeline connection piece, in particular to a quick assembly and disassembly convenient joint. Background technique [0002] At present, many connections between pipes and pipes and between pipes and valves are threaded or flanged, which is time-consuming and inconvenient, so people have developed quick-fit joints. [0003] For example, CN101526162B discloses a "two-way sealing and anti-pull-off plug-in quick-fit joint", including a joint body, a locking nut, an elastic pawl and an O-ring; the joint body is hollow, and a pipe body is arranged at one end of the joint body The connecting port is provided with a locking external thread on the outside of the connecting port of the pipe body, a locking nut is installed on the locking external thread, and an elastic pawl is installed in the connecting port of the pipe body. There is an O-ring in between. [0004] However, the elastic pawl and the lock nut are independent structur...
