Abstract

The utility model relates to a quick connector for pipelines, which is composed of a pipe sleeve, an expansion tightness sleeve, a pipe cap, etc. The end face of the sleeve body of the expansion tightness sleeve is made to a wedge-shaped face and matched with a wedge sleeve ring which is inosculated with the wedge-shaped face. The expansion tightness sleeve can be realize expansion deformation by pressing by screwing the pipe cap. Interference fit can be generated between the pipe sleeve and a being connected pipe, and the purpose that the pipe sleeve, the expansion tightness sleeve and the being connected pipe are firmly connected together can be achieved. People does not need to tap to pipe interfaces when maintenance or disassembly and assembly pipelines. The installation can be achieved only by inserting the being connected pipe to the expansion tightness sleeve and rotating the pipe cap. The quick connector for pipelines has good tightness, and can not leak water (air). Because the utility model has the advantages of simple structure and low manufacture cost, the quick connector for pipelines is easy to realize standardization, generalization and mass production. The utility model can replace the existing pipeline joints, such as a pipe joint, a movable joint, etc.

Description

The quick Communicating device of pipeline

The quick Communicating device of a kind of pipeline mainly is the pipeline Communicating device that is used between the conveyance conduit of water supply pipe or liquid gas.

As everyone knows, during pipe laying, skilled pipe fitter's need elder generation to the tapping of tube interface place, links together pipe by elbow, pipe joint, union sealing material etc. on pipe wrench platform or large-scale filament plate then.This traditional pipeline Placement is used in the building site and installs all right, make troubles to people if be used in to keep in repair to manage but in the family life, and there are the following problems: 1. labor intensity is big, as need carry heavy instrument when installing, resemble large-scale filament plate, pipe wrench platform, big spanner etc., also will be in the jointing tapping, and during maintenance, often, need dismounting adjacent a lot of pipes and joint in order to repair (changing) place's pipe joint; 2. after the mouth of pipe tapping, damage, make the joint corrosion because of crossing the zinc layer, cause the joint to leak (vapour), when needs are adjusted the direction of pipeline, must not much revolve big half-turn or screw big half-turn by force, also cause the joint to leak (vapour), or joint is twisted the phenomenon of splitting by force; 3. doing aforesaid operations must be the pipeline skilled labour, and common people can not finish.

The purpose of this utility model is: at the problems referred to above, design a kind of simple in structure, labor intensity is low, good seal performance, anyone can make things convenient for the quick Communicating device of brand-new pipeline that promptly pipe is connected together.

Design proposal of the present utility model is: according to the deformation principle of wedge shape extruding, select plastics for use.Polyamine fat.Metallic material is made the swelling cover, the both ends of the surface of body 5 are made sphenoid surface A, and are furnished with two wedge shape collars 6 that match with it, under pushing along the external force of axial direction, produce displacement, expand distortion, and produce friction, two pipes 1 that place in the body and the pipe box 3 that excessively cooperates with the external garden of cover are connect securely again, reach the connection purpose of pipe.

Outstanding effect of the present utility model is: 1. simple in structure, low cost of manufacture easily realizes standardization, generalization, production in enormous quantities; 2. owing to, just need not carry heavy instruments such as pincers platform, filament plate, only need to carry out dismounting during maintenance to repair, and need not dismantle adjacent pipe joints at damaged location without tapping, therefore efficient and convenient, reduce labor intensity; 3. because simple and practical, easy to operate, common people can the dismounting pipeline, and guarantees water-tight (vapour).

Below in conjunction with accompanying drawing the novel structure of this use is made specific description.

Fig. 1 is a structural drawing of the present utility model

Fig. 2 is the structural drawing of swelling cover 2 in the utility model

Fig. 3 is second kind of structure (threeway Communicating device) figure under the same design of the utility model

Fig. 4 is the third structure (elbow Communicating device) figure under the same design of the utility model

Know from Fig. 1, Fig. 2: the utility model is made up of swelling cover 2, sleeve pipe 3, pipe cap 4, swelling cover 2 usefulness plastics, polyester amine or metallic material manufacturing, it is to be made of the body 5 of two ends band sphenoid surface A, two wedge shape collars 6 matching with two ends sphenoid surface A respectively, pipe box 3 is contained on the outer garden of swelling cover 2 by transition fit, end at pipeline is provided with inward flange, axial displacement with restriction swelling cover 2, and having internal thread, the other end is connected with pipe cap 4, the center of pipe cap 4 is drilled with through hole, and connected two pipes 1 pass through hole and insert in the swelling cover 2.Rotation pipe cap 4, swelling cover 2 dilatancy that is squeezed, and produce stationary fit between pipe box 3 and the pipe 1 makes pipe box 3, and swelling cover 2 and pipe 1 are bound up securely.

Fig. 3 and Fig. 4 are other two kinds of embodiments of the same design of the utility model, pipe box 3 is made threeway pipe box 7 or elbow pipe box 8, processing ladder platform B with remaining piece 1 interface position, in order to moving axially of

restriction swelling cover

2,2 in the swelling cover of this moment needs body 5 and a wedge shape collar 6 to constitute, and these two kinds of structures are respectively applied for the connection of three pipes and the connection of bend pipe.

Claims

1. quick Communicating device of pipeline is characterized in that: it is made up of swelling cover 2, pipe box 3, the pipe cap 4 made of deformable material; Swelling cover 2 is again to be made of the body 5 of two ends band sphenoid surface A, two wedge shape collars 6 matching with two ends sphenoid surface A respectively, pipe box 3 is contained on the outer garden of swelling cover 2 by excessive cooperation, end face at pipe box 3 is provided with inward flange, and having internal thread, the other end is connected with pipe cap 4, the center of pipe cap 4 is drilled with through hole, and connected pipe 1 passes through hole and inserts in the swelling cover 2.

2. the quick Communicating device of pipeline according to claim 1, it is characterized in that: pipe box 3 can also be made into threeway pipe box 7, elbow pipe box 8 respectively, processing ladder platform B near mouth of pipe position, move axially in order to restriction swelling cover 2,2 in swelling this moment cover needs body 5 and a cambridge ring 6 to constitute.
