Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:

A kind of HDPE hollow wound pipe, including the first tube body 1 symmetrically open up on first tube body 1 there are two sliding slot 11, first 1 one end of tube body is fixedly welded with snap ring 12, and detent slot 121 is offered on snap ring 12, and the first tube body 1 is equipped with the first annulus 13, First annulus, 13 side is set there are four the first threaded hole 131, and 13 inner ring of the first annulus is symmetrically welded that there are two sliding block 14, the first circles 13 side of ring offers seal groove 132, is equipped with threaded post 16 in the first threaded hole 131,16 one end of threaded post is fixedly welded with rotation Button 17, the other end of threaded post 16 are equipped with nut 15, and 1 side of the first tube body is equipped with the second tube body 2；

Second tube body, 2 side offers annular groove 21, and 2 end of the second tube body is fixedly welded with the second annulus 22, the second circle It is opened up on ring 22 there are four the second threaded hole 221,22 side fixed bonding of the second annulus has sealing ring 23,21 inner ring bottom of annular groove Portion offers several spring grooves 26, and 26 bottom of spring groove is fixedly welded with several springs 25, and 25 one end of spring is fixedly welded There is inclined plate 24,24 bottom of inclined plate is fixedly welded with baffle 28, baffle plate groove 27 is offered below baffle 28.

Further, sliding slot 11 is not communicated with the external world, and sliding block 14 is embedded in sliding slot 11, sliding between sliding block 14 and sliding slot 11 Dynamic connection guarantees that the first annulus 13 can slide on 1 surface of the first tube body, and will not fall off.

Specifically, the length of threaded post 16 is greater than the sum of the thickness of the first annulus 13 and the second annulus 22, the first threaded hole 131 is identical with the aperture of the second threaded hole 221, and the position of the two corresponds to each other, between threaded post 16 and the first threaded hole 131 It and between threaded post 16 and the second threaded hole 221 is to be threadedly coupled.

It is worth noting that, being equipped with the screw thread being mutually twisted with threaded post 16 in nut 15, nut 15 can be in threaded post It is rotated on 16, nut 15 is removed from threaded post 16, when threaded post 16 passes through the first threaded hole 131 and the second threaded hole 221 Extend to it is outer after, nut 15 is nested into the extension end of threaded post 16, rotating nut 15 is in contact with the second annulus 22 to it, makes The connective stability between the first annulus 13 and the second annulus 22 can be increased by obtaining nut 15.

Further, the position of snap ring 12 and size are adapted with the position of detent slot 121 and size, seal groove 132 Position and size are adapted with the position of sealing ring 23 and size, are connected and fixed when between the first annulus 13 and the second annulus 22 Afterwards, sealing ring 23 is able to enter into seal groove 132, plays the role of sealing.

It is worth noting that, sealing ring 23 is made of natural rubber, natural rubber is non-toxic and tasteless, and elasticity is preferably, While playing sealing function, human body will not be damaged.

It is worth noting that inclined plate 24 is located at 21 inner ring end of annular groove, the position of inclined plate 24 and size and detent slot 121 Position and size be adapted, baffle plate groove 27 is provided with 21 inner ring bottom of annular groove, the height of baffle 28 and the depth of baffle plate groove 27 Degree is adapted, and the height of baffle 28 is adapted with the depth of detent slot 121, after snap ring 12 is completely into in annular groove 21, Baffle 28 can play the role of connecting and fixing to snap ring 12.

The HDPE hollow wound pipe of the present embodiment when in use, first when two HDPE hollow wound pipes need to connect, The annular groove 21 that the snap ring 12 of first tube body 1 is aligned on the second tube body 2 is slowly pushed into, at this time the inclined plate 24 of 21 end of annular groove It will be extruded, spring 25 will be retracted, then baffle 28 will enter in baffle plate groove 27, and snap ring 12 will enter to annular In slot 21, when the detent slot 121 moved on snap ring 12, then snap ring 12 would not again be squeezed inclined plate 24, the meeting again of spring 25 Restore to original state, then inclined plate 24 can restore to original state again, and baffle 28 will leave baffle plate groove 27, at this time entire inclined plate 24 and baffle 28 all in detent slot 121, and since the height of baffle 28 is adapted with the depth of detent slot 121, then baffle 28 will be to snap ring 12 play the role of connecting and fixing, and guarantee that two HDPE hollow wound pipes can be connected fixation, it is hollow to solve general HDPE The problem of connection is not sufficiently stable between winding pipe；

After the first tube body 1 is connect with the second tube body 2, the first annulus 13 on the first tube body 1 is pushed to arrive its end, at this time First annulus 13 is in contact with the second annulus 22, and nut 15 is removed from threaded post 16, rotates knob 17, drives threaded post 16 Rotation, so that threaded post 16 passes through threaded post 16 and the first screw thread also cross the first threaded hole 131 and the second threaded hole 221 Threaded connection between hole 131 and between threaded post 16 and the second threaded hole 221, so that the first annulus 13 and the second annulus 22 It is capable of fixing together, nut 15 is nested into the extension end of threaded post 16, rotating nut 15 connects to it with the second annulus 22 Touching, sealing ring 23 can also enter in seal groove 132 at this time, ensure that the leakproofness that the first tube body 1 is connect with the second tube body 2, The problem of solving the poor sealing connected between general HDPE hollow wound pipe, being easy infiltration.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
