Description
Technical field
The utility model relates to a kind of pipe joint, specifically a kind of rapid pipe joint of using in the automobile pipeline.
Background technique
In the automobile pipeline connected, the general at present joint structure that adopts all was threaded.In order to make joint not produce leakage, must make the fittings body that screws up with a wrench.But textural at automobile, a lot of assembly station spaces are narrow and small, use very inconvenience of spanner, also usually because be threaded generation leakage accident not in place.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, easy to assembly, the reliable sealing pipeline fast joint.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of rapid pipe joint, comprise the negative joint body, be positioned at the fixing ring of negative joint body, it is characterized in that: have screw thread to be connected in the described negative joint body with hollow bolt, between the end face of negative joint body and the hollow bolt seal ring is arranged, the quick inserting joint body is arranged in the described hollow bolt, and described quick inserting joint body is a body that connects, and head snap ring fluted and in the negative joint body is connected, the end face of head contacts with fixing ring, on the quick inserting joint body and between the hollow bolt endoporus seal ring is arranged.
The technological scheme that the utility model can also adopt is:
The shape of described fixing ring is circular, and its section is I-shaped.
Described snap ring is the flexible snap ring of U-shaped, and the two ends of its opening has bifurcation structure.
The quantity of the seal ring on the described quick inserting joint body is 2.
Described quick inserting joint body head has conical surface.
Because the utility model has adopted above-mentioned technical measures, make its contrast prior art that following advantage be arranged:
1, simple in structure, practicality.
2, easy to operate, improved efficiency of assembling greatly.
3, good seal performance, and low temperature resistant.

Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the structural representation of the utility model embodiment fixing ring;
Fig. 3 is the structural representation of the utility model embodiment snap ring.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
With reference to accompanying drawing, rapid pipe joint comprises negative joint body 1, hollow bolt 4 and 7 three critical pieces of quick inserting joint body.There is screw thread to be connected in the negative joint body 1, between the end face of negative joint body 1 and the hollow bolt 4 seal ring 6 arranged with hollow bolt 4.Quick inserting joint body 7 is arranged in the hollow bolt 4, and it is a body that connects, and is convenient to fluid and passes through.Snap ring 3 in the head of quick inserting joint body 7 fluted 8 and the quick inserting joint body 7 is connected.Snap ring 3 is the flexible snap ring of U-shaped, and the two ends of its opening has bifurcation structure 10.Snap ring can be made of nylon material.Quick inserting joint body 7 heads also have conical surface 9, are convenient to install and sealing.The end face of quick inserting joint body 7 heads contacts with the fixing ring 2 that is positioned at negative joint body 1.Fixing ring 2 be shaped as circle, its section is I-shaped, the sealing effect of this structure is better than the seal ring of general structure, is suitable for quick inserting joint.2 road seal rings 5 are arranged on the quick inserting joint body 7 and between hollow bolt 4 endoporus.
During installation, successively fixing ring 2, snap ring 3 are packed in the negative joint body 1, again hollow bolt 4 is screwed in negative joint body 1 screw thread.During connection, quick inserting joint body 7 is inserted in hollow bolts 4 and the negative joint body 1, snap ring 3 in the negative joint body 1 is snapped in the head recess 8 of quick inserting joint body 7 get final product.
