Serve as a contrast fixture.
Background technique
Line plastic-steel tube, using zinc-plated seamless steel pipe, welded still pipe as base tube, inner wall removal weldering muscle after, be lining into in galvanized pipe
The isometrical food-grade polyethylene of diameter (PE) tubing, last repressurization heating molding after a certain period of time are made, are widely used in all kinds of
The water supply system of the hot and cold water of building.
Line plastic-steel tube needs to be fixed by fixture in compound tense, and is to input compressed air in plastic tube into it,
Make plastics tube swelling, is bonded together plastics and steel pipe by hot melt adhesive under the pressure of compressed air.But it is existing
Fixture leakproofness is poor, there are problems that deflation gas leakage, to influence compound quality.
By the retrieval to patent document, patent document identical with present patent application is not found.
Summary of the invention
The purpose of this utility model is to provide a kind of scientific structure designs rationally, good airproof performance, improves the compound matter of product
The steel pipe measure, being easily achieved is compound to use liner fixture.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of steel pipe is compound to use liner fixture, it is characterised in that: is made of tetrafluoro housing and Pneumatic expanded core, described four
Fluorine housing is internally provided with coaxial starting tensioner core, one end of the Pneumatic expanded core and the threaded one end of tetrafluoro housing
Connection；The Pneumatic expanded core is by appendix, gas nozzle, connecting spring, end cap, threaded connector, washer, front-end block, rear end
Block and rubber piston ring are constituted, and are sequentially installed with end cap, threaded connector, washer, rear end from rear to preceding on the appendix
Block, rubber piston ring and front-end block are equipped with gas nozzle on the front end appendix of front-end block, in the corresponding appendix of rubber piston ring
Tube wall on be provided with stomata, connecting spring is installed on the rear end appendix of the end cap.
Moreover, the front end face of the front-end block is equipped with a circle slope structure.
Moreover, being evenly equipped with anti-sliding rib on the inner wall of the tetrafluoro housing.
It the advantages of the utility model and has the beneficial effect that
1, this steel pipe is compound uses liner fixture, when use by the modeling pipe portion that steelplastic pipe both ends are grown be placed in tetrafluoro housing with
At gap between Pneumatic expanded core, then, compressed air is inputted into appendix, at this point, rubber piston ring is because stress expands outward,
And then it is bonded modeling pipe tightly with tetrafluoro outer casing inner wall, it not only realizes the effect of fixed clamp, the effect of sealing is also functioned to, with this
Compressed air is entered inside modeling pipe by gas nozzle simultaneously, compounding machine heating, it is cooling under the action of complete answering for modeling pipe and steel pipe
Close work.
2, this steel pipe is compound uses liner fixture, by the design of slope structure in front-end block, facilitates the clamping of modeling pipe, mentions
Height clamping efficiency.
3, this steel pipe is compound uses liner fixture, by putting on the design of anti-skidding rib outside tetrafluoro, increases outside modeling pipe and tetrafluoro
The frictional force of inner room connects it stronger.
4, this steel pipe is compound uses liner fixture, by being tetrafluoro material by jacket designs, enhances the property of its high-low temperature resistant
Can, to enhance the service life of entire liner fixture.
5, design is scientific and reasonable for the utility model, has good airproof performance, improves product composite quality, firm grip, use
Service life is long, the advantages of being easily achieved, and being that a kind of steel pipe with higher innovation is compound uses liner fixture.

Specific embodiment
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of this utility model cannot be limited by this.
A kind of steel pipe is compound to use liner fixture, and innovation is: it is made of tetrafluoro housing 1 and Pneumatic expanded core,
The tetrafluoro housing is internally provided with coaxial starting tensioner core, one end of the Pneumatic expanded core and the one of tetrafluoro housing
End is threadedly coupled；The Pneumatic expanded core is by appendix 10, gas nozzle 9, connecting spring 8, end cap 7, threaded connector 6, washer
5, front-end block 2, back-end block 4 and rubber piston ring 3 are constituted, and are sequentially installed with end cap, screw thread from rear to preceding on the appendix
Connector, washer, back-end block, rubber piston ring and front-end block are equipped with gas nozzle on the front end appendix of front-end block, rise in rubber
It encloses on the tube wall of corresponding appendix and is provided with stomata, connecting spring is installed on the rear end appendix of the end cap.
The front end face of the front-end block is equipped with a circle slope structure.
Anti- sliding rib is evenly equipped on the inner wall of the tetrafluoro housing.
The modeling pipe portion that steelplastic pipe both ends are grown is placed at the gap between tetrafluoro housing and Pneumatic expanded core when use, so
Afterwards, compressed air is inputted into appendix, at this point, rubber piston ring is because stress expands outward, and then make modeling pipe in tetrafluoro housing
Wall is tightly bonded, not only realize fixed clamp effect, also function to the effect of sealing, at the same time compressed air by gas nozzle into
Enter to mould inside pipe, the compound work of completion modeling pipe and steel pipe under the action of compounding machine heating, cooling.
