Abstract
The invention discloses a metal fast-plug connector. The metal fast-plug connector comprises a metal shell, a metal clamping spring, a sealing ring and a locking check ring. The metal shell is a step pipe with the gradually-decreased inner diameters, and a first annular groove and a second annular groove are formed in the inner wall of the metal shell; the inner diameter of the first annular groove is larger than the inner diameter of the second annular groove, and the metal clamping spring is annularly arranged on the first annular ring in an interference fit manner; the sealing ring is clamped to the second annular groove through the locking check ring, and the locking check ring is annularly arranged on the second annular groove in an interference fit manner; and the minimum end of the inner diameter of the metal shell is a straight pipe portion. The metal fast-plug connector is simple and compact in structure, convenient to mount and low in cost, and the connecting and assembling efficiency can be improved; and the sealing performance of the connecting position of a gas pipeline and a liquid pipeline can be improved, and the high-temperature resisting performance is improved.
Description
Technical field
The present invention relates to a kind of metal quick inserting joint.
Background technique
In prior art, automotive pipeline connects the mode of structure connection mostly being rubber pipe and adding clip.But which exists following defect: 1, because its assembly connection is complicated, therefore, as there is this anatomical connectivity a large amount of during vehicle assembling, can efficiency of assembling be directly caused to decline; 2, rubber pipe adds yoke configurations mode and there is the defects such as join strength instability, sealing effect is poor, high-temperature behavior is poor.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the complicated and defect of switching performance difference of assembly connection that existing pipeline interconnection technique exists, providing a kind of metal quick inserting joint.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of metal quick inserting joint, its feature is, it comprises a metal shell, one metal jump ring, one seal ring and a locking back-up ring, described metal shell is the step pipe that internal diameter successively decreases step by step, the inwall of described metal shell is provided with one first circular groove and one second circular groove, the internal diameter of described first circular groove is greater than the internal diameter of described second circular groove, described metal jump ring is located on described first circular groove with interference fit, described seal ring is arranged in described second circular groove by described locking back-up ring, described locking back-up ring is located on described second circular groove with interference fit, the end that the internal diameter of described metal shell is minimum is a straight pipe portion.
Preferably, described seal ring is O RunddichtringO.
Positive progressive effect of the present invention is: structure is simple, compact, easy for installation, and cost is low, can improve connection and efficiency of assembling; The sealing of gas, liquid pipeline joint can also be improved, and improve resistance to high temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments.
Fig. 2 is the schematic perspective view after present pre-ferred embodiments plugs male connector.
Fig. 3 is the front elevational schematic after present pre-ferred embodiments plugs male connector.
Fig. 4 is A-A cross-sectional schematic in Fig. 3.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
As shown in Figure 1, a kind of metal quick inserting joint, it comprises metal shell 1, metal jump ring 2, locking back-up ring 3 and O RunddichtringO 4, the step pipe that metal shell 1 successively decreases step by step for internal diameter, the inwall of metal shell 1 is provided with the first circular groove and the second circular groove, the internal diameter of the first circular groove is greater than the internal diameter of the second circular groove, metal jump ring 2 is located on the first circular groove with interference fit, O RunddichtringO 4 is arranged in the second circular groove by locking back-up ring 3, locking back-up ring 3 is located on the second circular groove with interference fit, the end that the internal diameter of metal shell 1 is minimum is a straight pipe portion.
Metal jump ring in the present invention and locking back-up ring are existing conventional parts, just repeat no more at this.There is through hole conducting in the middle of metal shell, during use, male connector 5 is inserted metal quick inserting joint of the present invention, as shown in Figure 2, Figure 3 and Figure 4.The outer wall of male connector is typically provided with protruding annular ring.After male connector inserts, the annular ring of this projection can block by metal jump ring.The outer wall interference fit of seal ring and male connector, thus reach the effect of sealing.
The present invention can coordinate male connector to be dimensioned to different size, and the straight pipe portion of metal shell can be welded direct on pipeline and use, and also can weld the joint of difformity, size, as slub type, double-contracting type, refills and is fitted in gas, liquid pipeline.
Metal quick inserting joint structure of the present invention is simple, compact, easy for installation, and cost is low, can improve connection and efficiency of assembling; The sealing of gas, liquid pipeline joint can also be improved, and improve resistance to high temperature.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that this only illustrates, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection scope of the present invention.
