Abstract
The utility model provides a novel double-wall corrugated pipe connecting member which comprises a first connecting end and a second connecting end. An inner cavity of the first connecting end is composed of a smooth transition section and a cylinder section, the second connecting end is formed by sequentially socketing three barrels, multiple threaded holes are arranged on the peripheries of two barrels larger in inner diameter correspondingly, the two barrels are connected by an elastic member, and threaded holes arranged on the smooth transition section of the first connecting end correspond to the threaded holes on the barrels of the second connecting end. Bolts are arranged in the threaded holes of the two barrels larger in the inner diameter, and the barrel smallest in the inner diameter is socketed. The novel double-wall corrugated pipe connecting member has the advantages of being convenient and quick to mount, simple in structure, safe, reliable, low in maintenance cost, stable in connection, high in sealability and long in service life, and is suitable for mass production.
Description
Technical field
The utility model relates to a kind of bellows, especially relates to a kind of novel double-wall bellows joint member.
Background technique
Double-wall corrugated pipe for drainage material is to take polyethylene resin as main raw material, adds appropriate amount of addition agent, through extruding and moulding, is applicable to the novel tube that outdoor buildings draining and municipal blowdown are used.Having the advantages such as lightweight, resistance of water drainage is little, compressive strength is high, corrosion-resistant, easy construction, is the ideal material that replaces cast iron tube and Cement Concrete pipe.
It is mainly to rely on inspection shaft that current domestic double-wall corrugated pipe connects, be not specifically designed to the link of multichannel double-wall corrugated pipe, the method that inspection shaft connects is only applicable to outdoor remote connection, and when getting over roadbed or massif, pipeline also cannot be suitable for, moreover inspection shaft connects the needs that also do not meet laying in short distance or building.
Although have the link that is specifically designed to double-wall corrugated pipe abroad, the connecting means that it adopts compression type, relates to more assembly and special operation tool, uses more loaded down with trivial details.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of being connected firmly, novel double-wall bellows joint member easy for installation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel double-wall bellows joint member, comprises the first connecting end and the second connecting end; The inner chamber of described the first connecting end is comprised of a smooth transition section and a cylindrical cavity; Described the second connecting end is to be socketed to form successively by three cylinders; On the circumference of two cylinders that internal diameter is larger, correspondence is provided with a plurality of screws, and two larger cylinders of described internal diameter are connected by elastic member; The screw that the smooth transition section of described the first connecting end is provided with is corresponding with the screw on the cylinder of described the second connecting end.First in the screw of two larger cylinders of above-mentioned internal diameter, bolt is set, and then the cylinder of socket internal diameter minimum.
Further, the smooth transition section of described the first connecting end is horn-like and inwall and is provided with the groove passing through for bolt, and described groove extends to the screw place of cylindrical cavity always.
Further, the numerical value of the internal diameter of the cylindrical cavity of described the first connecting end is between the numerical value of the external diameter of two larger cylinders of described the second connecting end.
Further, described elastic member is spring.
Advantage and the good effect that the utlity model has are: first in the screw of two larger cylinders of above-mentioned internal diameter, bolt is set, and then the cylinder of socket internal diameter minimum, make at idle state, bolt is hidden between two larger cylinders of the second connecting end, and have the cylinder of internal diameter minimum spacing, it can not fallen down.During work, the second connecting end is stretched into the first connecting end, through smooth transition section, because the internal diameter of the internal cavity of the first connecting end diminishes gradually, cause two cylinders connecting by spring in the second connecting end power by compression, mutually close, bolt exposes the second connecting end by screw, continues motion until arrive the cylindrical cavity part of the first connecting end, and bolt is through the screw of this part, pass the first connecting end, by nut, fix.Have whole quick and easy for installationly, simple in structure, safe and reliable, maintenance cost is low, stable connection, and the advantage of the high and long service life of sealing, is applicable to producing in batches.

Embodiment
As shown in Fig. 1 or 2, the utility model provides a kind of novel double-wall bellows joint member, comprises the first connecting end 2 and the second connecting end 3; The inner chamber of described the first connecting end 2 is comprised of a smooth transition section and a cylindrical cavity; Described the second connecting end 3 is to be socketed to form successively by three cylinders; On the circumference of two cylinders that internal diameter is larger, correspondence is provided with a plurality of screws, and two larger cylinders of described internal diameter are connected by elastic member; The screw that the smooth transition section of described the first connecting end 2 is provided with is corresponding with the screw on the cylinder of described the second connecting end 3.The smooth transition section of described the first connecting end 2 is horn-like and inwall and is provided with the groove passing through for bolt 5, and the numerical value of internal diameter of cylindrical cavity of the first connecting end 2 is stated between the numerical value of the external diameter of two larger cylinders of described the second connecting end 3 in the screw place that described groove extends to cylindrical cavity always.Described elastic member is spring 4.
An embodiment of the present utility model: the first connecting end 2 and the second connecting end 3 are welded with respectively one section of bellows 1, first in the screw of two cylinders that internal diameter is larger in the second connecting end 3, bolt 5 is set, and then the cylinder of socket internal diameter minimum, make at idle state, bolt 5 is hidden between two larger cylinders of the second connecting end 3, and have the cylinder of internal diameter minimum spacing, it can not fallen down.During work, the second connecting end 3 is stretched into the first connecting end 2, through smooth transition section, because the internal diameter of the internal cavity of the first connecting end 2 diminishes gradually, cause two cylinders connecting by spring 4 in the second connecting end 3 power by compression, mutually close, bolt 5 exposes the second connecting end 3 by screw, continues motion until arrive the cylindrical cavity part of the first connecting end 2, and bolt 5 is through the screw of this part, pass the first connecting end 2, by nut, fix.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
