Abstract

The utility model discloses a pipe fitting coupling which is provided with ring pipe clips provided with elastic claws, and sealing rings, wherein, the pipe clips and the sealing rings are arranged inside the holes of coupling bodies such as a tee coupling, a straight coupling and an elbow. When assembled, a plastic pipe is inserted into the sealing ring and the holes of the pipe clips and then an end cover is used for fixation. When the pipes are disassembled, the end cover is screwed off, and the plastic pipe together with the pipe clips and the sealing ring is drawn out of the coupling. Elastic claws made from stainless steel inside the pipe clips limit the reverse drawing of the plastic pipe. The utility model has convenient assembly and disassembly, anti-abrasion capability, and is free from rust and leakage; the internal wall of the pipe fitting is smooth without resistance to the liquid.

Description

Pipe fitting joint

Technical field

The utility model relates to a kind of pipe fitting joint, specifically is meant the pipe fitting joint that plastic tube or plastic-aluminum pipe are connected with fittings bodies such as tee union, straight joint or elbows.

Background technique

Plastic tube is widely used in industry and civilian transfusion, gas transmission, and the installation of plastic tube be unable to do without pipe fitting joint, at present the plastic pipe joint that adopts two big classes are installed, a class is the hot melt connection, a kind of is the clamping type connection.The advantage that hot melt connects technology is to be connected firmly, and does not leak, and shortcoming is that technology is complicated, and hot melt can't be dismantled after connecting, and belongs to disposable connection.The advantage that clamping type connects is easy installation and removal, and connection reliability is poor during shortcoming, leaks easily, adapter sleeve is installed in the pipe during connection is formed bottleneck, and convection cell produces resistance, reduces flow.

Summary of the invention

The utility model provides a kind of pipe fitting joint, it is that annular pipe clamp and seal ring are installed in the hole of fittings bodies such as tee union, straight joint, elbow, plastic round tube is inserted in the hole of seal ring and pipe clamp, end cap compresses seal ring and pipe clamp, keep away in the pipe clamp fixing some slope inwardly, the elastic card claw of end band chisel teeth, elastic card claw blocks the outer wall of plastic tube.

The utility model is realized with following technological scheme: a kind of pipe fitting joint, comprise the fittings body that is produced on tee union or straight joint or elbow ends and be inserted into the plastic tube in the joint body opening and be installed in the end cap of fittings body end, it is characterized in that: the root of fittings body endoporus is made the circular hole that equates with the plastic tube external diameter, and plastic tube is inserted in this circular hole; Suit annular pipe clamp and seal ring successively in the step hole at fittings body middle part; End cap is installed in the end of fittings body by outside thread.

Described pipe clamp comprises tubular shape pipe clamp matrix and some elastic card claws that are fixed on the pipe clamp matrix inner hole wall; The even cloth of described elastic card claw one end is embedded in the interior garden cylinder of pipe clamp matrix, and the other end slopes inwardly, and the both sides, end make chisel teeth.

Good effect of the present utility model is:

1, quick and easy for installation, the fittings body of only pipe clamp, seal ring need being packed into during installation is inserted to plastic tube in the hole of seal ring, pipe clamp and fittings body again, tightens end cap and just can.

2, convenient disassembly only need take off end cap during dismounting, and plastic tube is extracted out from fittings body together with seal ring, pipe clamp, takes off pipe clamp again and seal ring just can.

3, good environmental protection, elastic card claw is made of corrosion resistant plate, and is anticorrosive.

4, mould smoothly in the plastic tube, convection cell produces choked flow.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the B-B sectional drawing of Fig. 2.

Among the figure: 1, fittings body, 2, pipe clamp, 2-1, pipe clamp matrix, 2-2, elastic card claw, 3, seal ring, 4, end cap, 5, plastic tube.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, pipe clamp 2 and seal ring 3 are installed in the hole of fittings body 1, make the chisel teeth of elastic card claw 2-2 inwardly most advanced and sophisticated, the end cap 4 of screwing on, make this moment and plastic tube 5 can be inserted in the hole of seal ring, pipe clamp 2 and fittings body 1, elastic card claw 2-2 just blocks plastic tube outer wall and makes it and can not outwards twitch, and tightens end cap 4 compresses seal 3 and makes it distortion, prevents to leak.Only need back out end cap 4 during dismounting, plastic tube 5 together goes out from fittings body 1 axis together with seal ring 3 pipe clamps 2, takes off pipe clamp 2 and seal ring 3 again.

Elastomeric joint 2-2 makes of stainless steel, pipe clamp matrix plastic production, and non-corrosive, corrosion-resistant, long service life.

Claims

1. pipe fitting joint, comprise the fittings body (1) that is produced on tee union or straight joint or elbow ends and be inserted into the plastic tube (5) in fittings body (1) hole and be installed in the end cap (4) of fittings body (1) end, it is characterized in that: the root of fittings body (1) endoporus is made the circular hole that equates with plastic tube (5) external diameter, and plastic tube (5) is inserted in this circular hole; Suit annular pipe clamp (2) and seal ring (3) successively in the step hole at fittings body (1) middle part; End cap (4) is installed in the end of fittings body (1) by outside thread.

2. pipe fitting joint according to claim 1 is characterized in that: described pipe clamp (2) comprises tubular shape pipe clamp matrix (2-1) and is fixed on some elastic card claws (2-2) on pipe clamp matrix (2-1) inner hole wall; The even cloth of described elastic card claw (2-2) end is embedded in the interior garden cylinder of pipe clamp matrix (2-1), and the other end slopes inwardly, and the both sides, end make chisel teeth.
