Problems solved by technology

[0003] Regardless of the assembly of the joint body assembly or the assembly of the parts on the valve body, after the assembly is completed, the sealing rings (22, 26), the locking ring 23 and the sealing gasket 24 are not easy to observe. The performance has a great impact; in addition, if the locking ring 23 fails to reset during insertion, the joint body 11 cannot be locked, and the joint body 11 will come out of the screw sleeve body 21 when the pipeline system is pressurized

Abstract

The invention discloses a quickly inserted joint assembly for a vehicle pipeline system. The quickly inserted joint assembly for the vehicle pipeline system comprises a quickly inserted joint assemblyand a joint body assembly. One end of the quickly inserted joint assembly is a quickly inserted end and is assembled in the joint body assembly; the other reverse end is a pipeline connecting end andis assembled in a hose of a pipeline; the quickly inserted joint comprises a joint main body, a first seal ring, a second seal ring and a lock ring; one end of the joint body assembly is a barrel main body for inserting the quickly inserted joint and the other end of the joint body assembly is an external thread connected to a pipe connecting part; the joint body assembly comprises a barrel mainbody, a third seal ring, a joint main body and a fourth seal ring; and a self-locking fixing device is formed between the quickly inserted assembly and the joint body assembly to achieve one-way locking of the quickly inserted joint assembly. By implementing the quickly inserted joint assembly disclosed by the invention, the quantity of parts of the quickly inserted joint assembly is reduced and the parts are subpackaged conveniently; the lock ring is locked and reset through a primary locking position and a secondary locking position, and the secondary locking function is increased equivalently, so that the connecting reliability among the parts is improved.

Description

technical field [0001] The invention relates to the technical field of quick-connect joints, and more particularly relates to a quick-plug joint assembly for a vehicle piping system. Background technique [0002] At present, quick-plug connector components have been widely used in vehicle piping systems, such as Figure 1-3 As shown, it is the form of push-in joint commonly used in the air brake system pipeline at present. The push-in joint assembly generally includes a push-in joint assembly and a joint body assembly; the push-in joint assembly consists of a joint body 11 and two sealing Rings (12, 13); the joint body assembly is composed of six parts: the screw sleeve main body 21, two sealing rings (22, 26), the locking ring 23, the sealing gasket 24 and the joint body main body 25. The assembly of the push-in joint assembly is to first set the two sealing rings (12, 13) on the joint main body 11, and then assemble the dustproof cap (remove it for use) to complete the ass...
