Description

Plastic dustproof cap of PE pipe

Technical Field

The utility model belongs to the technical field of the plastics cap that prevents dust, specifically be a plastics cap that prevents dust of PE pipe.

Background

The PE pipe is a polyethylene plastic pipe, generally comprises two types of pipes, namely a medium-density polyethylene pipe and a high-density polyethylene pipe, and is divided into SDR11 series and SDR17.6 series according to the wall thickness, wherein the former is suitable for conveying gaseous artificial gas, natural gas and liquefied petroleum gas, and the latter is mainly used for conveying natural gas.

PE pipe is batch production basically, and after production was accomplished, can stack and accomodate, if the storage time is of a specified duration, especially the great PE pipe of pipe diameter, very easily gets into spot such as dust in it, deposits for a long time, and the problem of corruption can appear in the pipeline inner wall, uses for the later stage and causes the influence.

Therefore, the dust caps are generally added at two ends of the PE pipe during the storage of the PE pipe, but the existing dust caps are simple in structure and basically similar to cap structures, when the PE pipe is horizontally placed, the cap can be stably covered, but when the PE pipe is transferred, the PE pipe shakes or collides, the cap can be separated, and if the PE pipe is not timely found to be covered again, the inner wall of the pipeline can be adhered by dust or corroded by dirt.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a plastics dustproof cap of PE pipe to solve traditional PE pipe dustproof cap simple structure's problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a plastics dust cap of PE pipe, includes the pipeline body, the pipeline body coats and is stamped the apron, be fixed with the arch on the apron, the parcel has annular gasbag in the arch, the inner wall of pipeline body is hugged closely to annular gasbag, be fixed with the barrel on the apron, be fixed with the stopper on the inner wall of barrel, it has the thread bush to fix the embedding on the inner wall of barrel, the thread bush internal thread is provided with the screw thread knob, the outer wall of pipeline body is hugged closely to the tip of screw thread knob.

Preferably, the cover plate and the bulge are both cylindrical, and the central points correspond to each other, so that the sealing effect of plugging the annular air bag is ensured.

Preferably, the annular air bag is made of rubber materials, and the annular air bag can seal the inner wall of the port of the pipeline body by virtue of an expansion effect.

Preferably, the contact surface of the limiting block and the outer wall of the pipeline body is arc-shaped, so that the contact laminating effect is ensured.

Preferably, the cover plate, the protrusion and the cylinder are of an integrated structure, so that the sealing and dust-proof stability is ensured.

Preferably, the cover plate is provided with a built-in groove, and a handle is fixed in the built-in groove and can drive the cover plate to move.

Preferably, the cover plate, the protrusion, the cylinder body, the limiting block, the threaded knob, the threaded sleeve and the handle are all made of plastic materials, and the plastic materials are low in manufacturing cost and convenient to produce and use in a large scale.

Compared with the prior art, the beneficial effects of the utility model are that: can cover the tip of pipeline body through the apron, the cooperation annular gasbag can carry out the shutoff to pipeline inner wall port position and seal, guarantees sealed effect, simultaneously, through the locking effect of spiral knob for whole dust cap can be fastened more with the pipeline body, makes it when removing, is difficult for breaking away.

Fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a structural diagram of the limiting block and the threaded knob of the present invention;

fig. 3 is a structural diagram of the airbag and the protrusion of the present invention.

In the figure: 1. a pipe body; 11. a cover plate; 12. a protrusion; 13. an annular air bag; 14. a barrel; 15. A limiting block; 16. a threaded knob; 17. a threaded sleeve; 2. a built-in groove; 21. a handle.

Detailed Description

Referring to fig. 1, 2 and 3, a plastic dust cap for a PE pipe includes a pipe body 1, a cover plate 11 covers the pipe body 1, a protrusion 12 is fixed on the cover plate 11, an annular air bag 13 is wrapped on the protrusion 12, the annular air bag 13 is tightly attached to an inner wall of the pipe body 1, a cylinder 14 is fixed on the cover plate 11, a stopper 15 is fixed on an inner wall of the cylinder 14, a threaded sleeve 17 is fixedly embedded on an inner wall of the cylinder 14, a threaded knob 16 is arranged in an internal thread of the threaded sleeve 17, and an end of the threaded knob 16 is tightly attached to an outer wall of the pipe body 1.

Referring to fig. 1, the cover plate 11 and the protrusion 12 are both cylindrical and have corresponding central points, so as to ensure the sealing effect of the annular air bag 13.

Referring to fig. 1, the annular air bag 13 is made of rubber material, and can seal the inner wall of the port of the pipeline body 1 by expansion.

Referring to fig. 1, the contact surface of the limiting block 15 and the outer wall of the pipeline body 1 is arc-shaped, so that the contact fitting effect is ensured.

Referring to fig. 1, the cover plate 11, the protrusion 12 and the cylinder 14 are of an integrated structure, so that the sealing and dust-proof stability is ensured.

Referring to fig. 1, the cover plate 11 is provided with an internal groove 2, and a handle 21 is fixed in the internal groove 2 and can drive the cover plate 11 to move.

Referring to fig. 1, the cover plate 11, the protrusion 12, the barrel 14, the stopper 15, the threaded knob 16, the threaded sleeve 17 and the handle 21 are made of plastic materials, and the plastic materials are low in manufacturing cost and convenient to produce and use in a large scale.

The working principle of the scheme is as follows: when the port position of pipeline body 1 needs to be sealed up, through the handheld whole dust cap of handle 21, then laminate apron 11 at the tip of pipeline body 1, arch 12 drives annular gasbag 13 and enters into the inner wall of pipeline body 1 this moment, annular gasbag 13 is through the effect that the extrusion resets, the realization is sealed to the inner wall of pipeline body 1, the outer diameter of annular gasbag 13 is greater than the inner wall of pipeline body 1 and is no more than three millimeters, when the inner wall that enters into pipeline body 1, by the extrusion, through inside vacuum inflation, make it enter into behind the inner wall of pipeline body 1, can hug closely the inner wall of pipeline body 1.

Then after the butt joint is completed, the limiting block 15 is tightly attached to the outer wall of the pipeline body 1, and then the threaded knob 16 is rotated to enable the limiting block 15 and the threaded sleeve 17 to generate a relative position, so that the limiting block is tightly attached to the outer wall of the pipeline body 1 and is matched with the limiting block 15 to realize a locking effect.
