Description
Technical field
The utility model belongs to water pipe head technical field, is specifically related to a kind of cooling water pipe quick coupling.
Background technique
In automobile industry, the connection that can be usually related between two sebific ducts, in the prior art, by banjo fixing butt jointing by two
After sebific duct connection, need to be held tightly the connecting portion of sebific duct and banjo fixing butt jointing with clip, installation steps are cumbersome, and very time-consuming is taken
Power, and it is easy to appear the not tight problem of clip card, generate drainage.In addition, being also easy to that clip occurs during installation clip
The problem of flicking causes installation personnel injured.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cooling water pipe quick coupling, and operator utilizes
It can carry out the quick connection between two sebific ducts, can be with overcome the deficiencies in the prior art.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of cooling water pipe quick coupling, it is wrapped
The inner cylinder and outer barrel for including coaxial arrangement, are connected between inner cylinder and outer barrel by stripper loop, and the stripper loop will be interior
It is formed by annular cavity between cylinder and outer barrel and is separated into two annular slots, is set on the lateral wall at inner cylinder both ends
There is annular convex platform, offer annular seal groove on the lateral wall of annular convex platform, O-shaped sealing is installed at annular seal groove
Circle.
Above-mentioned cooling water pipe is that the annular convex platform is equipped with chamfering with quick coupling, can expand annular slot in this way
Interface oral area, the connecting pin of sebific duct can be made smoothly to be inserted into annular slot.
Above-mentioned cooling water pipe is to be additionally provided with hangnail on the lateral wall of the annular convex platform, in this way may be used with quick coupling
The frictional resistance between sebific duct and inner cylinder is increased, prevents sebific duct from deviating from cooling water pipe quick coupling.
Above-mentioned cooling water pipe is that the length of the inner cylinder is less than the length of outer barrel with quick coupling.
Compared with the prior art, the beneficial effects of the utility model are: passing through stripper loop phase between inner cylinder and outer barrel
Connection, stripper loop will be formed by annular cavity and be separated into two annular slots between inner cylinder and outer barrel, in inner cylinder
Annular convex platform is set on the lateral wall at both ends, annular seal groove is opened up on the lateral wall of annular convex platform, at annular seal groove
O-ring seal is installed, such structure is inserted into annular slot convenient for the connecting pin of two sebific ducts, is improved between two sebific ducts
Joint efficiency, it is extremely time saving and energy saving, it can be effectively prevented by the close contact of O-ring seal and inner cylinder and two sebific ducts
Drainage occurs for the junction of two sebific ducts.Meanwhile the utility model also has ingenious in design, structure simple and is easily installed and tears open
The advantages of unloading.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is structural schematic diagram when the utility model is connected with two sebific ducts.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only the section Example of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
As shown in Fig. 1, a kind of cooling water pipe quick coupling, it includes the inner cylinder 1 and outer barrel 2 of coaxial arrangement,
It is connected between inner cylinder 1 and outer barrel 2 by stripper loop 3, the stripper loop 3 will be formed between inner cylinder 1 and outer barrel 2
Annular cavity be separated into two annular slots 4, annular convex platform 5 is equipped on the lateral wall at 1 both ends of inner cylinder, in convex annular
Annular seal groove 6 is offered on the lateral wall of platform 5, and O-ring seal 7 is installed at annular seal groove 6.
In order to be inserted into the connecting pin of sebific duct smoothly in annular slot, the annular convex platform 5 is equipped with chamfering 8, makes annular
The interface oral area of slot expands.
Sebific duct deviates from cooling water pipe quick coupling in order to prevent, is additionally provided with down on the lateral wall of the annular convex platform 5
Thorn, increases the frictional resistance between sebific duct and inner cylinder.
Specifically, the length of the inner cylinder 1 is less than the length of outer barrel 2.
This structure of the utility model is inserted directly into annular slot convenient for the connecting pin of two sebific ducts, improves two sebific ducts
Between joint efficiency, can be prevented by the close contact of O-ring seal and inner cylinder and two sebific ducts in the junction of two sebific ducts
Drainage occurs.
The preferred embodiment in the utility model disclosed above is only intended to help to illustrate the utility model.Preferred embodiment is simultaneously
There is no the details that detailed descriptionthe is all, also not limiting the utility model is only the specific embodiment.Obviously, according to this theory
The content of bright book can make many modifications and variations.Embodiment is chosen and specifically described to this specification, be in order to preferably explain
The principles of the present invention and practical application, so that skilled artisan be enable to better understand and utilize this practical
It is novel.
