Technical Field

The invention relates to the technical field of constructional engineering, in particular to a conical sleeve for sealing between an embedded sleeve and a downpipe.

Background

At present, in traditional building engineering, the sealing between a pre-buried sleeve and a downpipe is generally blocked by adopting a fireproof dense material, so that the construction is inconvenient and the appearance is not attractive.

Disclosure of Invention

The invention provides a conical sleeve for sealing between an embedded sleeve and a downpipe, which aims to solve the problems of the prior art and comprises a pipe body, wherein a cylindrical sleeve is arranged above the pipe body, a conical sleeve is arranged below the pipe body, the cylindrical sleeve and the conical sleeve are integrally manufactured, an upper opening is formed above the cylindrical sleeve, a lower opening is formed below the conical sleeve, and the edge of the lower opening is turned outwards to form a U-shaped turning bend.

Further, the diameter of the lower opening is larger than that of the upper opening.

Furthermore, the pipe body is made of PVC materials.

By adopting the technical scheme, the method has the following beneficial effects:

the invention has simple structure, convenient use and low manufacturing cost, ensures the sealing effect between the embedded sleeve and the downpipe, and has good waterproof effect and beautiful appearance.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example 1: the conical sleeve for sealing between the embedded sleeve and the downpipe as shown in fig. 1-2 comprises a pipe body 5, wherein a cylindrical sleeve 1 is arranged above the pipe body 5, a conical sleeve 2 is arranged below the pipe body 5, the cylindrical sleeve 1 and the conical sleeve 2 are integrally manufactured, an upper opening 3 is formed above the cylindrical sleeve 1, a lower opening 4 is formed below the conical sleeve 2, and the edge of the lower opening 4 is turned outwards to form a U-shaped turning 10.

The diameter of the lower opening 4 is larger than that of the upper opening 3, and the pipe body 5 is made of PVC materials.

When the water seepage prevention device is used specifically, the pipe body 5 is sleeved into the water falling pipe 6, the embedded sleeve 7 is wrapped below the pipe body 5, the upper part of the U-shaped bend 10 is directly covered when the floor surface layer 8 is manufactured, the structural layer 9 is arranged below the floor surface layer 8, the upper opening 3 is connected with the water falling pipe 6 through special PVC glue, and therefore the water seepage hidden danger can be effectively prevented.

The invention has simple structure, convenient use and low manufacturing cost, ensures the sealing effect between the embedded sleeve 7 and the downpipe 6, and has good waterproof effect and beautiful appearance.

Having thus described the basic principles and principal features of the invention, it will be appreciated by those skilled in the art that the invention is not limited by the embodiments described above, which are given by way of illustration only, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
