Annular groove is offered on one internal perisporium, the sealing ring is arranged in the annular groove, and the tube body one passes through with the tube body two
Helicitic texture engages, and to the sealing ring is bonded with the tube body biend, the shrinkable sleeve is set on the tube body one, described
On the peripheral surface of two joint of tube body, the tube body one, the tube body two are bonded with the inner wall of the heat-shrink tube respectively.
Tube body one is being carried out with tube body two when docking, heat-shrink tube is initially placed on tube body one and is located at joint, pyrocondensation
The internal partial wall of pipe is contacted with tube body one, and during tube body one is docked with two screw-thread fit of tube body, heat-shrink tube is arranged immediately
In on tube body two, the inner wall of another part of heat-shrink tube is contacted with tube body two, meanwhile, the sealing ring and pipe being placed in inside tube body one
Body biend is bonded.After the docking of tube body one and tube body two, heat-shrink tube is heated, makes to produce after heat-shrink tube is heated
Raw certain shrinkage passes through sealing ring to make tube body one, tube body two be fitted closely together with the inner wall of heat-shrink tube respectively
With being used cooperatively for heat-shrink tube, enhance pipeline joint sealing performance, even if there is screw thread because of long-time service in pipeline
The sealing performance of sliding phenomenon, sealing ring and heat-shrink tube can also prevent the generation of drainage, to improve making for drainpipe
It is cost-effective with the service life.
Further, in the joint of the tube body one and the tube body two, the inner peripheral surface of the tube body one is equipped with spiral shell
The peripheral surface of line, the tube body two is equipped with screw thread, and the tube body one is connect with the tube body two by screw-thread fit.
Best, internal diameter of tube body A of the tube body one in the joint is more than the internal diameter B of the sealing ring.
Best, the internal diameter of tube body A is more than internal diameter of tube body C of the tube body one far from the joint.
Best, the internal diameter of tube body C is equal to the internal diameter B of the sealing ring.
The internal diameter of tube body of tube body one is arranged to two kinds, after tube body one is docked with tube body two, can ensure that sealing ring exists
Position is fixed between tube body one and tube body two, and tube body one is pressed with the both ends of sealing ring respectively with tube body two, to ensure to seal
Circle position does not shift, and ensures sealing effect, improves the leak resistance of total.
Best, the tube body one, the tube body two are plastic tube or metal tube.
Advantageous effect:Compared with prior art, the utility model has the advantages that:On the basis of pipeline thread engages, increase
If sealing ring and heat-shrink tube, make total joint sealing performance more preferably, to effectively prevent the generation of drainage,
The service life of drainpipe is improved, it is cost-effective, ensure the normal life of user.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model.
A kind of connection structure for drain-pipe, as shown in Figure 1, including tube body 1, tube body 22, sealing ring 3, heat-shrink tube 4, tube body
One 1, tube body 22 is plastic tube or metal tube;Annular groove 11 is offered on the internal perisporium of tube body 1, sealing ring 3 is arranged in annular groove 11
In, tube body 1 is engaged with tube body 22 by helicitic texture, wherein the inner peripheral surface of tube body 1 is equipped with screw thread, tube body 22
Peripheral surface is equipped with screw thread, and sealing ring 3 is bonded with 22 end face of tube body, and the internal diameter of tube body of tube body 1 is two kinds, is located at sealing ring 3
Side is simultaneously internal diameter of tube body A close to joint, is internal diameter of tube body C positioned at 3 other side of sealing ring, and internal diameter of tube body A is more than pipe
Internal diameter C, the internal diameter B of sealing ring 3 is equal with internal diameter of tube body C, heat-shrink tube 4 be sheathed on tube body 1,22 joint of tube body outside
On circumferential surface, tube body 1, tube body 22 are bonded with the inner wall of heat-shrink tube 4 respectively.
Heat-shrink tube is initially placed on tube body one and is located at joint, and the internal partial wall of heat-shrink tube is contacted with tube body one, seals
Circle is arranged in the inside of tube body one, and during tube body one is docked with two screw-thread fit of tube body, heat-shrink tube is sheathed on pipe immediately
On body two, the inner wall of another part of heat-shrink tube is contacted with tube body two, meanwhile, the sealing ring and tube body two being placed in inside tube body one
