Disclosure of Invention

An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a plastic sewage pipes's butt joint lantern ring.

The utility model provides a technical scheme that above-mentioned problem adopted is: including the pipeline body, cup joint in proper order each other between the pipeline body and become to connect access structure as an organic whole, cup jointed the lantern ring between the pipeline body, the surface of pipeline body is the ripple face, and its inboard surface is smooth pipeline face, and the tip between two adjacent pipeline bodies cup joints the setting each other, cup joints the lantern ring at the position that cup joints each other, the lantern ring integrated into one piece is the loop configuration to its cross-section shaping is "C" shape structure, and the opening position of the lantern ring is pegged graft on the edge of the pipeline body of cup jointed one end, and the lantern ring shaping is for lieing in the inside liner limit of pipeline body and lieing in the sealed limit in the pipeline body outside, cup joints the outside pipeline body tip closely and pegs graft in the outer lane on sealed limit relatively. This device is a lantern ring structure for connecting plastic pipeline among the blowdown engineering, and the function of main realization is the leakproofness that improves the cup joint to avoid the pine of the lantern ring to take off, increase the frictional force of the lantern ring and the cup joint structure, and guaranteed the cup joint structure compressive strength. The service life of the pipeline is prolonged, the leakage is reduced, and the repeated repair and maintenance are avoided.

In the structure of this device, mainly be the structure that cup joints each other between two plastic pipeline, the plastic pipeline structure inlayer of blowdown is smooth pipe wall structure usually, be corrugated structure in relative skin, smooth and smooth degree that smooth pipe wall improves the circulation, and corrugated structure improves the compressive resistance of pipeline, because always there is the error of precision between the pipeline, lug connection can not reach inclosed effect, so just adopt the mode of the lantern ring to connect, and the structure of the lantern ring is the fluting that has "C" shape, the fluting lock joint is at the edge of plastic pipeline, can improve frictional force greatly, reduce the problem of slippage, the outside of the lantern ring sets up the structure that the external diameter progressively increases simultaneously, outside frictional force has been increased, improve the compactness of cup jointing.

Further, the sealing edge is formed into a conical annular structure with gradually enlarged diameter, the edge of the rear end of the sealing edge is formed into a blocking edge higher than the highest position of the conical ring, and the blocking edge is in contact with the end face of the end part of the pipeline body sleeved on the outer side. The blocking edge is used for closing the edge of the pipeline body positioned on the outer side and closing seepage of the edge.

Furthermore, a recess corresponding to the edge of the pipeline body is formed at the junction of the blocking edge and the conical annular structure, and the edge corresponding to the pipeline body is accommodated. The sunken effect plays when the pipeline docks, clearly indicates its pipeline of butt joint to peg graft in place, avoids the error of connecting to appear in the in-process of butt joint.

Further, the outer side surface of the pipe body at the sleeved end of the pipe body is formed into a friction surface, the inner side surface of the sleeved part of the pipe body is also formed into a friction surface, and the lantern ring is sleeved with the friction surfaces at the two ends and is in tight contact with the friction surfaces. The friction surface can increase the connection firmness of the lantern ring.

Furthermore, the friction surface is regularly formed into a structure with a plurality of arrayed annular grooves or protrusions, corresponding grooves or protrusions are oppositely and correspondingly formed on the corresponding surface of the lantern ring, and the grooves or the protrusions are mutually connected in an involution mode. The regular structure of the friction surface can increase the structural area and improve the firmness of the sleeve joint.

Further, the length of the lining edge of the collar is not less than 1/4 of the length of the sealing edge. The length of the lining edge cannot be too short, so that the problem of slippage is easy to occur.

Compared with the prior art, the utility model, have following advantage and effect: this device is a lantern ring structure for connecting plastic pipeline among the blowdown engineering, and the function of main realization is the leakproofness that improves the cup joint to avoid the pine of the lantern ring to take off, increase the frictional force of the lantern ring and the cup joint structure, and guaranteed the cup joint structure compressive strength. The service life of the pipeline is prolonged, the leakage is reduced, and the repeated repair and maintenance are avoided.
