Abstract

The utility model discloses a single-socket connected H pipe which comprises a pair of standpipes, and mitre pipes connected with the standpipes with an included angle with the standpipe axis of 45 degrees; the external diameter of a mitre pipe 4 on a first standpipe 11 is reduced to be equal to the external diameter of a straight pipe 3, and the length is doubled; the external diameter of a mitre pipe 5 on a second standpipe 12 is not changed, and an elliptical ring-shaped step 6 is reserved at a joint of the inner wall of the mitre pipe 5 with the second standpipe 12. Therefore, during installation, the prolonged part of the first mitre pipe 4 can be inserted completely into the second mitre pipe 5, and contact the elliptical ring-shaped step 6 which has spacing effect, and thus the center distance between the standpipes is ensured to meet design requirements after the first mitre pipe is installed in place. The utility model has the advantages of convenient and simple assembly, reliable sealing, and material saving.

Description

Single socket joint connects the H pipe

Technical field

The utility model relates to a kind of single socket joint and connects the H pipe, belongs to the chemical building material technical field.

Background technology

In order to solve the problem of highrise building drainage pipe ventilation, eliminate the noise that when draining, produces because partial pressure is poor, need to be set up in parallel independently air duct; And by the conjugation pipe, claim H pipe drainage pipe and air duct to be communicated with into an integrated piping system again.

Existing widely used H pipe mostly is separate type, specifically sees Chinese patent CN300883595.This H pipe is 45 ° straight tube 3 by a pair of standpipe 2 with inclined pipe 1 and end face and axis and combines, and two vertical tube structures, configuration design are just the same, make workload thereby reduced mould; Straight tube 3 is formed by the tubing cutting of extrusion molding, and during use, straight tube 3 two ends external surfaces are smeared an amount of glue, successively inserts in the inclined pipe, and the connection of two standpipes is as a whole, and realizes sealing by adhesive.This structure only need design a mold, has: die manufacturing cost is low, and socket joint connects simply and easily advantage.But two 45 ° of end faces of straight tube 3 are difficult to parallel cutting, and unavoidably have scarcely circularity during the straight tube extrusion molding, cause to install to be difficult to put in place, and installation difficulty is large, sealing effectiveness after the impact assembling; Twice socket joint connects also very trouble during assembling, so require further improvement.

Certainly, Chinese patent 200820112933.X has also announced a kind of design of integral structure H pipe, but complex structure, consume material are its unsurmountable shortcomings; So, improve for separate type H pipe and to seem more meaningful. ?

Summary of the invention

The purpose of this utility model is: change structure and the size of inclined pipe on two standpipes, form single socket joint and connect, save straight tube, install, improve the sealing reliability after connecting thereby simplify.

The utility model is achieved through the following technical solutions: at first, the outside dimension of the first inclined pipe 4 is reduced to the outside dimension of straight tube and equates on the first standpipe 11, and length prolongs one times; So that the part of the first inclined pipe 4 after prolonging can be inserted in the second inclined pipe 5 on the second standpipe 12 fully.Secondly, the size constancy of the second inclined pipe 5 on the second standpipe 12, the inwall of the second inclined pipe 5 is reserved an oval circular step 6 in the place of passing through mutually with the second standpipe 12 outer walls, and the shoulder height size equates with straight tube 3 wall thickness dimensions, limits the insertion depth of the first inclined pipe 4.At last, after the first inclined pipe 4 inserts and is in place, the center to center distance size conforms designing requirement between two standpipes.

The utility model has the advantage of: the first, by changing the size and dimension of the first inclined pipe 4 on the first standpipe 11, so that forming single socket joint with the second inclined pipe 5, the first inclined pipe 4 is connected; The straight tube that has solved prior art H pipe is connected, assembles respectively the problem of inconvenience with twice socket joint of inclined pipe.The second, the first standpipe 11 and the first inclined pipe 4, the second standpipe 12 and the 5 injection mo(u)lding processing and manufacturings of the second inclined pipe, technical matters is ripe, dimensional accuracy is high, assembling is easy, and joint face is tight after the assembling, and sealing is reliable.The 3rd, save straight tube and saved material, also reduced the workload of cutting 45 ° of end faces.

Single socket joint that the utility model is introduced connects the H pipe, can adopt PVC, PPR, the processing and manufacturing of ABS thermoplastic injection molding, and quality is light, intensity is high, assembling is easy, cost of production is low, result of use is good.

Fig. 1: the design sketch of prior art H pipe;

Fig. 2: the utility model list socket joint connects the design sketch of H pipe;

Fig. 3: the utility model list socket joint connects the oval circular step design sketch of H pipe.

The specific embodiment:

Fig. 2 has provided a kind of embodiment of the present utility model.Single socket joint connects the H pipe and is comprised of the two parts that separate, and adopts PVC-U, PPR, ABS thermoplastic injection mo(u)lding processing and manufacturing.Be applied to Φ 110mm * 3.2mm and meet the H pipe that the system support of GB/T5836.1 hard polyvinyl-chloride drainage pipe for building road is installed: design standpipe up and down bellmouth internal diameter is that Φ 110mm, wall thickness are not less than 3.2mm; The first inclined pipe external diameter Φ 75mm, wall thickness 2.3mm, the second inclined pipe internal diameter Φ 75mm, wall thickness 2.5mm, length dimension designs as required; During installation, the first inclined pipe external surface and the second inclined pipe inner surface are evenly smeared respectively sealing glue, and the first inclined pipe fully inserts in the second inclined pipe, contacts with the oval ring step, and standpipe is communicated with.

Claims
