Description
Technical field
The present invention relates to a kind of metal quick connector.
Background technology
In the prior art, automotive pipeline connection is generally that rubber tube adds the frame mode of clip to connect.But, which is deposited
In following defect：1st, because its assembly connection is complicated, therefore, as there are a large amount of structure connections when vehicle is assembled, can directly it lead
Efficiency of assembling is caused to decline；2nd, rubber tube add yoke configurations mode to exist bonding strength is unstable, sealing effectiveness is poor, high-temperature behavior is poor
Etc. defect.
The content of the invention
The technical problem to be solved in the present invention be in order to the assembly connection for overcoming existing pipeline interconnection technique to exist is complicated and
There is provided a kind of metal quick connector for the defect of switching performance difference.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of metal quick connector, its feature is that it includes a metal shell, a metal jump ring, a sealing ring and one
Locking back-up ring, the metal shell is the step pipe that internal diameter successively decreases step by step, and the inwall of the metal shell is first annular provided with one
Groove and one second annular groove, the internal diameter of the first annular groove are more than the internal diameter of second annular groove, the metal jump ring with
Interference fit is located on the first annular groove, and the sealing ring is arranged in second annular by the locking back-up ring
Groove, the locking back-up ring is located on second annular groove, the end of the internal diameter minimum of the metal shell with interference fit
Portion is a straight sections.
It is preferred that the sealing ring is O-ring seal.
The positive effect of the present invention is：Simple in construction, compact, easy for installation, cost is low, can improve connection and fill
With efficiency；The sealing of air-liquid line connection can also be improved, and improves resistance to elevated temperatures.
Brief description of the drawings
Fig. 1 is the structural representation of present pre-ferred embodiments.
Fig. 2 is that present pre-ferred embodiments plug the schematic perspective view after male contact.
Fig. 3 is that present pre-ferred embodiments plug the schematic elevation view after male contact.
Fig. 4 is A-A schematic cross-sectional views in Fig. 3.
Embodiment
Name preferred embodiment, and become apparent from intactly illustrating the present invention with reference to accompanying drawing.
As shown in figure 1, a kind of metal quick connector, it includes metal shell 1, metal jump ring 2, locking back-up ring 3 and O-shaped close
Seal 4, metal shell 1 is the step pipe that internal diameter successively decreases step by step, and the inwall of metal shell 1 is provided with first annular groove and the second annular
Groove, the internal diameter of first annular groove is more than the internal diameter of the second annular groove, and metal jump ring 2 is located on first annular with interference fit
Groove, O-ring seal 4 is arranged in the second annular groove by locking back-up ring 3, and locking back-up ring 3 is located on second with interference fit
Annular groove, the end that the internal diameter of metal shell 1 is minimum is a straight sections.
Metal jump ring and locking back-up ring in the present invention are existing conventional part, are just repeated no more herein.Metal-back
There is through hole conducting in the middle of body, in use, male contact 5 to be inserted to the metal quick connector of the present invention, as shown in Figure 2, Figure 3 and Figure 4.
The annular ring of projection is typically provided with the outer wall of male contact.After male contact insertion, metal jump ring can be by the raised annular ring
Block.The outer wall interference fit of sealing ring and male contact, so as to reach sealed effect.
The present invention can coordinate male contact to be dimensioned to different sizes, and the straight sections of metal shell can be welded direct to pipe
Used on road, the joint of different shape, size can also be welded, such as slub type, double-contracting type are refilled and be fitted in air-liquid pipeline.
The metal quick connector of the present invention is simple in construction, compact, and easy for installation, cost is low, can improve connection and assembling effect
Rate；The sealing of air-liquid line connection can also be improved, and improves resistance to elevated temperatures.
Although the embodiment of the present invention is the foregoing described, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
On the premise of the principle and essence of the present invention, various changes or modifications can be made to these embodiments, but these changes and
Modification each falls within protection scope of the present invention.
