Abstract

The utility model discloses a pipe fitting joint, wherein a stainless steel ring claw, a ring pressure pad and a seal ring are arranged in holes of joint bodies which are a tee joint, a straight joint or an elbow and the like. When installing, plastic pipes just need to be inserted into the holes of the seal ring, the ring pressure pad, the stainless steel ring claw and the joint bodies, an end cover is screwed down, thereby better limiting the pumping of the plastic pipes at the return direction. When dismantling, the end cover just needs to be taken down, and the plastic pipes are pumped out from the joint body together with the seal ring, the ring pressure pad and the stainless steel ring claw. The dismounting is convenient, and the pipe fitting joint resists corrosion and does not leak.

Description

Pipe fitting joint
Technical field
The utility model relates to a kind of pipe fitting joint, is specifically related to 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 be equipped with two kinds, the one, hot melt connects, another kind is the clamping type connection.The advantage that hot melt connects technology is to be connected firmly, and does not leak, and shortcoming is the technology more 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 shortcoming is that connection reliability is poor, leaks easily.
Summary of the invention
The purpose of this utility model provides a kind of pipe fitting joint, is the pipe fitting joint that plastic tube or plastic-aluminum pipe are connected with fittings bodies such as tee union, straight joint or elbows.
The utility model is achieved by the following technical solution: 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, there is outside thread the end of fittings body, the root of fittings body endoporus is made the circular hole that matches with the plastic tube external diameter, and plastic tube is inserted in this circular hole: the annular claw of suit stainless steel, annular pressure pad and seal ring successively in the step hole at fittings body middle part; End cap is installed in the end of fittings body by the outside thread of fittings body end.
Described stainless steel annular claw outer circumferential edge is attached to the inner cylindrical surface of fittings body end, and the internal tooth limit slopes inwardly, and the internal tooth limit is made as chisel teeth.
Good effect of the present utility model is:
1, quick and easy for installation, only need during installation plastic tube is directly inserted in the hole of fittings body, tighten end cap and get final product.
2, convenient disassembly only need take off end cap during dismounting, extracts out to get final product from fittings body.
3, good environmental protection, annular claw is made of stainless steel, and is anticorrosive.
4, energy-conservation, the fittings body aperture is big, and water amount is big.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done and to be described in further detail.
Accompanying drawing is the utility model structural representation;
Among the figure: 1, fittings body, 2, stainless steel annular claw, 3, annular pressure pad, 4, seal ring, 5, end cap, 6, plastic tube.
Embodiment
As shown in drawings, a kind of 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 6 in fittings body 1 hole and be installed in the end cap 5 of fittings body 1 end, there is outside thread the end of fittings body 1, the root of fittings body 1 endoporus is made the circular hole that matches with plastic tube 6 external diameters, and plastic tube 6 is inserted in this circular hole; Suit stainless steel annular claw 2, annular pressure pad 3 and seal ring 4 successively in the step hole at fittings body 1 middle part; End cap 5 is installed in the end of fittings body 1 by the outside thread of fittings body 1 end.
Described stainless steel annular claw 2 outer circumferential edge are attached to the inner cylindrical surface of fittings body 1 end, and the internal tooth limit slopes inwardly, and the internal tooth limit is made as chisel teeth.
As shown in drawings, stainless steel annular claw 2, annular pressure pad 3, seal ring 4 are installed in the hole of fittings body 1, make the internal tooth limit of stainless steel annular claw 2 inside, the end cap 5 of screwing on, can insert plastic tube 6 in the hole of seal ring 4, annular pressure pad 3, stainless steel annular claw 2 and fittings body 1 this moment, stainless steel annular claw 2 just blocks plastic tube 6 outer walls and makes it and can not outwards twitch, and tightens end cap 5 compresses seal 4 and makes it distortion, prevents to leak.Only need back out end cap 5 during dismounting, plastic tube 6 is extracted from fittings body 1 together with seal ring 4, annular pressure pad 3, stainless steel annular claw 2, takes off the annular claw 2 of stainless steel, annular pressure pad 3, seal ring 4 again and gets final product.
Stainless steel annular claw 2 usefulness stainless steels are made, and annular pressure pad 3 is used plastic production, and non-corrosive is corrosion-resistant, long service life.
