Abstract
The utility model provides a double-wall corrugated pipe connection end comprising a first connection end and a second connection end. Both the first and second connection ends are connected with a double-wall corrugated pipe; a plurality of clamping grooves are circumferentially arranged in the first connection end; grooves identical with the clamping grooves in number are arranged at places corresponding to the second connection end, each groove is provided with a spring, and the free end of the spring is connected with a lug; anti-back uprights are arranged on the inner wall of each of the first connection end and the second connection end. The double-wall corrugated pipe connection end has the advantages of being convenient and rapid in overall mounting, simple in structure, safe and reliable, low in maintenance cost, stable in connection, high in airtightness, long in service life and suitable for mass production.
Description
Technical field
The utility model relates to a kind of bellows, particularly a kind of double-wall corrugated pipe connection end.
Background technique
Double-wall corrugated pipe for drainage material is 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 double-wall corrugated pipe connection end simple in structure, easy to connect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of double-wall corrugated pipe connection end, comprises the first connection end and the second connection end that are connected with double-wall corrugated pipe; On described the first connection end, along circumference, be provided with multiple draw-in grooves; Described the second connection end correspondence is provided with the groove of equal number, is fixed with spring in groove, and the free end of described spring connects a projection; Described the first connection end and the second connection end inwall are provided with anti-back column.
Further, described projection and draw-in groove interference fit.
Further, the external diameter of described the first connection end and the second connection end interference fit and the second connection end equals the internal diameter of the first connection end.
Further, the longitudinal cross-section of described anti-back column is right-angled triangle; The central shaft of described the first connection end is pointed on the summit of the anti-back column in the first connection end, and the central shaft of described the second connection end is pointed on the summit of the anti-back column in the second connection end.
Advantage and the good effect that the utlity model has are: the present invention, by the draw-in groove and the corresponding groove arranging of the second connection end that arrange along circumference on the first connection end, is fixed with spring in groove, the free end of spring connects a projection; When the first connection end docks with the second connection end, projection clamping groove, realizes the connection of two ends bellows.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 Figure 1, the utility model provides a kind of double-wall corrugated pipe connection end, comprises the first connection end 2 and the second connection end 4 that are connected with double-wall corrugated pipe; On described the first connection end 2, along circumference, be provided with multiple draw-in grooves 1; Described the second connection end 4 correspondences are provided with the groove of equal number, are fixed with spring in groove, and the free end of described spring connects a projection 3; Described the first connection end 2 and the second connection end 4 inwalls are provided with anti-back column 5.Projection 3 and draw-in groove 1 interference fit.The external diameter of the first connection end 2 and the second connection end 4 interference fit and the second connection end 4 equals the internal diameter of the first connection end 2.The longitudinal cross-section of anti-back column 5 is right-angled triangles; The central shaft of described the first connection end 2 is pointed on the summit of the anti-back column 5 in the first connection end 2, and the central shaft of described the second connection end 4 is pointed on the summit of the anti-back column 5 in the second connection end 4.
An embodiment of the present utility model is: as shown in Figure 2, the first connection end 2 is connected with the bellows interference of one end, the second connection end 4 is connected with the bellows interference of the other end, multiple sawtooth on bellows respectively with 5 interlocks of anti-back column, the longitudinal cross-section of anti-back column 5 is that the hypotenuse of right-angled triangle and anti-back column 5 is in face of the approach axis of bellows.By the draw-in groove 1 and the corresponding groove arranging of the second connection end 4 that arrange along circumference on the first connection end 2, in groove, be fixed with spring, the free end of spring connects a projection 3; When the first connection end 2 docks with the second connection end 4, projection 3 clamps groove, realizes the connection of two ends bellows.
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.
