Abstract

The utility model relates to a quick coupling, comprising a shell part and a bamboo joint part, wherein the middle parts of the shell part and the bamboo joint part are conducted by through holes. The inner surface of the shell part is provided with an annular groove of the position of a limit male coupling, and a sealing ring is buckled in the annular groove by a locking check ring. The outer side surface of the shell part is provided with a jump ring groove corresponding to the surface groove of the male coupling, and a metal baffle ring is arranged in the jump ring groove to lock the surface groove of the male coupling. The quick coupling has the advantages for increasing the tightness and pull-out force of the connecting position of gas and liquid pipelines and the connecting assembly efficiency, and the practicability is strong.

Description

Quick inserting joint

Technical field

The utility model relates to a kind of negative joint that is applicable to gas, liquid pipeline, relates in particular to the structure of this joint.

Background technique

Automobile mostly is the mode of structure connection that rubber pipe adds clip with the pipeline connection in the prior art, but this mode exists assembling to connect complexity.During the vehicle assembling, as exist a large amount of these mode of structure to connect, can directly influence whole efficiency.And there is the join strength instability in this mode of structure, and sealing effect is poor, can't realize shortcomings such as assembling under the component environment, is necessary and need be improved.

Summary of the invention

The utility model technical issues that need to address have provided a kind of quick inserting joint, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: housing parts, ring part; In the middle of described housing parts and the ring part through hole conducting is arranged; The annular groove of one spacing male connector position is set at the internal surface of described housing parts; One seal ring is stuck in the annular groove by a locking back-up ring; The outer surface of housing parts be provided with one with the corresponding jump ring groove of male connector surface groove; The one metal baffle ring locking male connector surface groove in the jump ring groove of packing into.

Compared with prior art, the beneficial effects of the utility model are: improved sealing and the pull-out force of gas, liquid pipeline joint, and the efficiency of assembling that connects, practicability is stronger.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

By Fig. 1, Fig. 2 as seen: the utility model comprises: housing parts 1, ring part 5; In the middle of described housing parts 1 and the ring part 5 the through hole conducting is arranged; The annular groove 6 of one spacing male connector, 10 positions is set at the internal surface of described housing parts 1; One seal ring 2 is stuck in the annular groove 6 by a locking back-up ring 3; The outer surface of housing parts 1 be provided with one with male connector 10 surface grooves 11 corresponding jump ring grooves 7; The one metal baffle ring 4 locking male connector surface groove in the jump ring groove 7 of packing into.

The direction of change ring can make joint be changed to 90 ° (as shown in Figure 3), 135 ° (as shown in Figure 4), 180 ° of structures such as (as shown in Figure 5) in the utility model, and the quantity of change ring can make joint be changed to bypass structure, tee union (as shown in Figure 6), three-dimensional threeway structures such as (as shown in Figure 7).In the middle of body shell and the ring part through hole conducting is arranged.Seal ring assembly is installed in the enclosure interior groove, and seal ring cooperates with the outer wall that is connected male connector, reaches sealing effect by male connector crush seal circle.The metal baffle ring is installed in the outer grooves place of body shell, by with male connector on groove fit to reach male connector can't be deviate from, and increase the effect of pull-out force.When this kind joint uses, can get final product according to the size that the size of pipeline internal diameter is regulated ring.

Body shell is that the other end partly is made of ring by high-strength engineering plastic injection moulding processing in the utility model, and this ring part is connected with pipeline; Body shell the other end inner chamber is provided with seal ring assembly, and seal ring assembly is made up of seal ring and locking back-up ring.Seal ring is by the groove of locking back-up ring clip at inner chamber; When connecting the male connector assembling, be inserted into body shell inside, the metal baffle ring snaps onto the groove that connects male connector, guarantees quick inserting joint and is connected male connector and can throw off; The front end external diameter crush seal circle that connects male connector makes it sealing part and fits, and guarantees the product sealing.

Claims

1. a quick inserting joint is characterized in that comprising: housing parts, ring part; In the middle of described housing parts and the ring part through hole conducting is arranged; The annular groove of one spacing male connector position is set at the internal surface of described housing parts; One seal ring is stuck in the annular groove by a locking back-up ring; The outer surface of housing parts be provided with one with the corresponding jump ring groove of male connector surface groove; The one metal baffle ring locking male connector surface groove in the jump ring groove of packing into.
