Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

the utility model provides a PPR anti-freezing pipe, as shown in fig. 1 and 2, including body one 1, body two 6 and fixed connection keep away from the wide-mouth portion 7 of body one 1 one end in body two 6, the flexible pipe 5 of fixedly connected with between body one 1 and the body two 6, and be equipped with the spacing subassembly that is located the flexible pipe 5 outside between body one 1 and the body two 6, the internal diameter of wide-mouth portion 7 equals the external diameter of body one 1, body one 1 has been kept away from and has been seted up annular spout 2 on the one side periphery wall of body two 6, the connecting cylinder 3 is equipped with to annular spout 2 endotheca, and the length of annular spout 2 is greater than the length of connecting cylinder 3, the one end sliding connection that body two 6 was kept away from to annular spout 2 has the seal assembly 4 of external diameter more than or equal to wide-mouth.

As shown in fig. 3, one side fixedly connected with external screw thread 21 that annular spout 2 is close to body two 6, set up the internal thread with external screw thread 21 threaded connection on the internal perisporium of connecting cylinder 3, through setting up internal thread and external screw thread 21, thereby when making connecting cylinder 3 take place the displacement in annular spout 2, can play the direction effect through both, and when connecting cylinder 3 avoids reverse displacement in annular spout 2, can carry out the interlock through internal thread and external screw thread 21, thereby make connecting cylinder 3 receive the ascending spacing of displacement side.

Seal assembly 4 includes rubber circle 41 and rubber circle two 42 of sliding connection in annular chute 2, the thickness of rubber circle 41 and rubber circle two 42 begins the crescent setting from one side of mutual orientation, and its cross-section is right trapezoid, and sliding connection has two contact pieces 43 that are located between rubber circle 41 and the rubber circle two 42 in annular chute 2, contact piece 43 adopts stainless steel, when seal assembly 4 takes place elastic deformation, can come to extrude rubber circle 41 through rubber circle two 42, it is spacing to the deformation direction of rubber circle 41 and rubber circle two 42 through two contact pieces 43 that have certain hardness, thereby make rubber circle 41 and rubber circle two 42 can outwards expand.

As shown in fig. 4 and 5, a plurality of slideways 61 are provided on the outer peripheral wall of the second tube body 6, the limiting component comprises a positioning column 81 fixedly connected to the outer peripheral wall of the first tube body 1, a limiting plate 82 fixedly connected to the positioning column 81, and a sliding block 83 fixedly connected to the limiting plate 82 and slidably connected to the inside of the slideway 61, and by setting the limiting component, the telescopic tube 5 can be effectively supported, when the telescopic tube 5 stretches, the limiting plate 82 can limit the telescopic tube 5, and the limiting component can slide in the slideway 61 through the sliding block 83 to adapt to the length change of the telescopic tube 5.

And the outside coating of body 1, body two 6, wide-mouth portion 7 and flexible pipe 5 has black rubber coating, because the coating is black to make whole pipeline can absorb the heat energy of light in daytime, thereby make the pipeline have certain heat, avoid taking place to freeze the circumstances in winter, and rubber coating still has the cold-proof effect of certain degree, makes the heat can obtain the maintenance of a period.

Whole pipeline is when connecting, people only need get two root canals way, let body 1 of a pipeline insert in the wide-mouth portion 7 of another pipeline, then people are through rotating connecting cylinder 3, a plurality of anti-skidding lines 31 have been seted up on the periphery wall of connecting cylinder 3, thereby make people can make things convenient for people to have an effect when rotating connecting cylinder 3, the condition of skidding avoids appearing, and under the guide effect of internal thread and external screw thread 21, connecting cylinder 3 takes place the displacement in the type of remodeling spout, and exert the effort to seal assembly 4.

When the sealing component 4 receives acting force, the rubber ring II 42 exerts acting force on the rubber ring I41, the two contact pieces 43 are limited by the rubber ring I41 and the rubber ring II 42, the rubber ring I41 and the rubber ring II 42 can be expanded outwards, the outer diameters of the rubber ring I41 and the rubber ring II 42 are enlarged, and therefore the two pipelines are effectively connected and a good sealing effect is achieved.

When the length of pipeline is not good enough simultaneously, people can directly stimulate body one 1 and body two 6 to make flexible pipe 5 take place the extension, body one 1 can drive the slide 61 of slider 83 on body two 6 through reference column 81 and limiting plate 82 and take place the displacement simultaneously, thereby makes spacing subassembly shelter from in the outside of flexible pipe 5 all the time, makes flexible pipe 5 can not take place the flagging condition.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
