Description

Detachable quick coupling
Technical field
The utility model is related to pipe joint, more particularly to a kind of detachable quick coupling, it is adaptable to small-bore (below external diameter 32mm) feedwater polypropylene plastics pipeline, polybutene plastic conduit, metal compounded pipe.
Background technology
At present, plastic tube or plastic-metal composite pipe typically use mechanical pipe joint, but the pipe joint generally existing to pacify Dress inconvenience is, it is necessary to special tool(s), difficulty and defect that the easy leak of long-term use cannot be safeguarded.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of dismountable quick pipe connecting Head, it is easy for installation without instrument, can reuse, connection reliability is high, and antileaking, later maintenance and member replacing are convenient.
In order to realize the above object the utility model is adopted the following technical scheme that:
A kind of detachable quick coupling, including adapter body, housing, retaining ring, fixed mount, buckle and sealing Part, the termination of the housing sets housing screw thread, and the end of adapter body sets and main body screw is threadedly coupled with housing, described Fixed mount is the pipe that periphery middle part is provided with flange, and in one end insertion adapter body of fixed mount, the flange outside diameter of fixed mount is more than The internal diameter of adapter body, the flange of fixed mount is stuck in housing, and the other end of fixed mount is set to horn mouth, described retaining ring Ring set and grabbed to the pin of ring contract along place, the pin of retaining ring is grabbed in the horn mouth for inserting fixed mount, and pin is grabbed as outside can be to ring The thin slice of expansion, described buckle is inserted from housing away from adapter body port, and the inwall of housing sets embedded buckle outer wall Protuberance in groove, the insertion end outer wall of buckle is fitted in the inwall on ring edge.
The adapter body is Cu alloy material or engineering plastics, and the afterbody of the main body screw of adapter body sets retaining Groove, the corresponding tight locking button set in embedded back stop slot of the afterbody of the housing screw thread of housing, back stop slot is matched somebody with somebody with the tight locking button of housing Close, can prevent housing pine from moving back.
Can filling sealed part between described fixed mount and adapter body 1.
Further, the pin of retaining ring grabs the projection that thin slice inner side sets triangle, further in order to increasing friction force Promptly outer pipe wall;
Further, pin is grabbed and is set to the thin slice that two-layer is interlocked, triangular hill, two-layer are set between two-layer thin slice Thin slice increases dynamics promptly, further prevents tubing from coming off.
The utility model is in close contact by the seal being provided with groove with tubing, sealing is formed, so that antileaking; And adapter body is used with housing and is threadedly coupled, and is easily installed, the back stop slot in main body coordinates with the tight locking button of housing, prevents Housing comes off because being produced with water pressure circulation impact, screws out housing by tight locking button is lifted during dismounting, it is easy to change close Sealing, solves the problems, such as that later maintenance is difficult.
The utility model is compared with the prior art, and fully shows that it is advantageous in that:It is easy for installation, without instrument, connection Reliability is high, and antileaking and later maintenance are simple, detachably enable part Reusability.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model, but the embodiment should not be understood It is to limitation of the present utility model.
As shown in figs 1-9:A kind of detachable quick coupling, including adapter body 1, housing 2, retaining ring 3, fixation Frame 4, buckle 6 and seal 5, the termination of the housing 2 set housing screw thread 2.1, and the end of adapter body 1 sets main body screw 1.1, housing 2 is connected through a screw thread with adapter body 1, and described fixed mount 4 is provided with the pipe of flange, fixed mount 4 for periphery middle part One end insertion adapter body 1 in, more than the internal diameter of adapter body 1, the flange of fixed mount 4 is stuck in for the flange outside diameter of fixed mount 4 In housing 2, the other end of fixed mount 4 is set to horn mouth, and the ring of described retaining ring 3 is set to ring contract along at 3.1 Pin grabs 3.2, and the pin of retaining ring 3 is grabbed in the horn mouth of 3.2 insertion fixed mounts 4, pin grab 3.2 for can to outside ring expand thin slice, institute The buckle 6 stated is inserted from housing 2 away from the port of adapter body 1, and the inwall of housing 2 sets prominent in the embedded outer wall groove of buckle 6 Go out portion, the insertion end outer wall of buckle 6 is fitted in the inwall that ring is along 3.1.
The adapter body 1 is Cu alloy material, and the afterbody of the main body screw of adapter body 1 sets back stop slot 2.1, housing Housing screw thread 2.1 the corresponding tight locking button 2.2 set in embedded back stop slot 2.1 of afterbody, the locking of back stop slot 2.1 and housing Button 2.2 coordinates, and can prevent housing pine from moving back.
Can filling sealed part 5 between described fixed mount 4 and adapter body 1.
Further, the pin of retaining ring 3 grabs the projection that 3.2 thin slices inner side sets triangle, enters in order to increasing friction force One step firmly grasps outer pipe wall;Further, pin is grabbed 3.2 and is set to the thin slice that two-layer is interlocked, three are set between two-layer thin slice Angular projection, two-layer thin slice increases dynamics promptly, further prevents tubing from coming off.
Screw-threaded coupling assembling of the present utility model completes the shaping of product, and the cooperation of tight locking button and back stop slot avoids screw thread Freely loosen, when artificial reinforcing is reversely rotated, housing can be pulled down, change sealing ring or miscellaneous part.The retaining ring 3 In the cavity that housing 1 and fixed mount 4 are formed;The buckle 6 is pacified in adapter body 1, housing 2, retaining ring 3, fixed mount 4 After the completion of dress, frock directly can be completed by the press-in of housing oral area.
When tubing is connected, need to will only carry out in the tubing insertion joint of chamfering, reach bottom;
When tubing is extracted, by buckle to internal pressure, make retaining ring extension, you can extract tubing;
