In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a PE threading pipe of convenient concatenation, includes the body and connects, the surface of body is equipped with the ring channel, and the ring channel evenly sets up the surface at the body, the left end inboard that connects is provided with the stopper, and the stopper is the ring channel piece and connects integrated into one piece, the stopper is pegged graft in the inboard of ring channel, the right-hand member inboard that connects is provided with the location arch, and the location arch is 4 protruding rings and connects integrated into one piece, the location arch is located the inboard of ring channel.

Preferably, the right side surface that connects is provided with the mouth that tightens, and the quantity of tightening mouth is 4 and evenly sets up a week on connecting the right side.

Preferably, the surface of the joint is provided with an external thread, and the surface of the external thread is in threaded connection with a positioning nut.

Preferably, the joint inboard center is provided with the spacing ring, and the both ends butt of spacing ring has the body.

Preferably, a reinforcing layer is disposed on the inner side of the pipe body.

Compared with the prior art, the beneficial effects of the utility model are that: when the pipe bodies are connected, the pipe bodies are inserted into the inner part of the joint and abutted against the limiting ring, the pipe body in the left side of the joint is inserted into the inner side of the annular groove through the limiting block for positioning, and the pipe body in the right side of the joint is positioned by inserting the positioning protrusion into the annular groove through the positioning nut along the external threads to prevent the pipe bodies from being connected loosely, so that gaps are prevented from being generated at the connecting part between the pipe bodies, and the phenomenon of pause and contusion during; meanwhile, the annular groove formed in the surface of the pipe body meets the requirement that the pipe body is connected again after being cut off.

Drawings

FIG. 1 is a sectional view of the overall structure of the present invention;

fig. 2 is a schematic view of the overall structure of the present invention.

In the figure: the pipe comprises a pipe body 1, an annular groove 11, a reinforcing layer 12, a joint 2, a limiting ring 21, a limiting block 22, a positioning bulge 23, a tightening opening 24, a positioning nut 25 and an external thread 26.

Detailed Description

Please refer to fig. 1, a PE threading pipe convenient for splicing, including body 1 and joint 2, the surface of body 1 is equipped with ring channel 11, ring channel 11 evenly sets up the surface at body 1, the left end inboard that connects 2 is provided with stopper 22, stopper 22 pegs graft in the inboard of ring channel 11, stopper 22 inserts ring channel 11 inboard and fixes a position body 1 that the left side connects 2 inside, the right-hand member inboard that connects 2 is provided with location arch 23, location arch 23 is located the inboard of ring channel 11, location arch 23 inserts ring channel 11 inboard and fixes a position body 1 that connects 2 right side inside.

Referring to fig. 1 and 2, a tightening opening 24 is formed on the right side surface of the joint 2, and the tightening opening 24 is contracted inward to drive the positioning protrusion 23 to be inserted inward into the annular groove 11.

Referring to fig. 1 and 2, the surface of the connector 2 is provided with an external thread 26, the surface of the external thread 26 is connected with a positioning nut 25 in a threaded manner, and the positioning nut 25 rotates along the external thread 26 to loosen or tighten the left side of the connector 2.

Referring to fig. 1, a limiting ring 21 is disposed at the center of the inner side of the joint 2, the limiting ring 21 and the joint 2 are integrally formed, the pipe bodies 1 are abutted to both ends of the limiting ring 21, the thickness of the limiting ring 21 is the same as that of the pipe bodies 1, and after the limiting rings 21 are abutted to the pipe bodies 1, the pipe bodies 1 and the limiting ring 21 are in the same level.
