Abstract

The utility model relates to a pipeline connector, which is composed of a pipe connection body, a clamping head, a sealing ring which is arranged on the inner opening of the pipe connection body, and a circular clamping spring which is inserted between the clamping head and a connection pipe, wherein, the clamping spring forms the circular cylinder clamping spring through a plurality of elastic clamping sheets, and barb is arranged on each clamping sheet head. When the utility model is used and installed, the clamping head is sheathed on the clamping spring and then sheathed in the connection pipe, and the connection pipe is inserted in the pipe connection body to the sealing ring. The clamping head and the clamping spring are plugged tightly, so the utility model can be fixed. The utility model has the advantages of convenient use, low cost, good sealing performance, strong versatility, etc., and is especially suitable for the connection of plastic pipes or aluminum plastic composite pipes.

Description

Plastic pipe joint

The utility model relates to a kind of pipe joint.

Existing pipe joint is of a great variety, but all adopts metallic material to make, and metal connecting piece causes environmental pollution in process of production easily, and the cost height, install inconvenient.

It is a kind of quick for installation, convenient that the purpose of the utility model is to provide, the plastic pipe joint of good airproof performance.

In order to achieve the above object, the technical solution of the utility model is such: it is by the pipe junctor, chucking head and place the seal ring on the pipe junctor internal orifice and insert the chucking head and take between garden shape jump ring composition.

Do not come off in order to ensure taking over, the utility model is made the tubular jump ring of being made up of 4-8 sheet elastic card with jump ring, and the card head is provided with hangnail, and card head outer surface is the taper of protrusion.

Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.

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

Fig. 2 is the utility model jump ring structural representation.

Fig. 3 is the A-A sectional view of Fig. 2.

Fig. 4 is the another kind of pipe of a utility model junctor structural representation.

Referring to Fig. 1, plastics are taken over by pipe junctor 1, chucking 3 and place the seal ring 2 in the pipe junctor 1 and insert chucking 3 and jump ring 4 compositions of taking between 5.The interface inwall of pipe junctor 1 is made two cast stages, and inner step is put O-ring seals 2, and outer stage is made the limit dais of chucking 3.Take over 5 for convenience and connect, the port inner wall of chucking 3 is split into horn-like, and the internal diameter of its external diameter and chucking 3 matches, and the internal diameter of jump ring 4 is slightly less than the external diameter of adapter 5.

Jump ring 4 is formed the tubular jump ring by equally distributed 6 elastic cards 6, and there is card head 7 on card 6 tops, and its inwall is provided with hangnail 8, makes that taking over 5 advances not move back, and card head 7 outer walls are the cone-shaped of protrusion, referring to Fig. 2, and Fig. 3.

When the utility model use to be installed, will tighten 3 earlier and be enclosed within on the jump ring 4, again they will be inserted in adapter 5, to take over 5 insertion tube junctors 1 then to seal ring 2, and will tighten 3 and jump ring 4 embed in pipe junctors 1 port, make and take over 5 roof pressures and on seal ring 2, seal, and make and take over 5 and fix.

Pipe junctor 1 of the present utility model can be made into the pipe junctor 1 of different size shape as required, the pipe junctor 1 of the curved formula pipe junctor 1 in Three way type pipe junctor 1 as shown in Figure 1 or angle shown in Figure 4 or other geometric format.

Obviously, the utlity model has easy to usely, cost is low, good airproof performance, and advantages such as highly versatile, the pipeline that is specially adapted to industries such as industry, medical treatment, building, fire-fighting connects.
