Description

Technical Field

[0001] The present application relates to the field of anti-leakage devices, and in particular to an anti-leakage device for drainage pipes. Background Art

[0002] The drainage system is an important infrastructure of modern cities. In the construction of municipal and environmental governance projects, the drainage system often accounts for a large proportion of investment.

[0003] With the continuous development of urban construction, there are many types of municipal pipelines, one of which is the indispensable pipe. When the municipal water supply and drainage pipes are installed and used, the drainage pipes are usually wrapped with water stop tape or sealed with flanges at the joints.

[0004] The traditional sealing effect of using water stop strips or flanges at drainage pipe connections needs to be improved, and the installation process is relatively difficult. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present application provides a drainage pipe anti-seepage device.

[0006] The present application provides a drainage pipe anti-seepage device adopts the following technical solution:

[0007] A drainage pipe anti-seepage device comprises a first drainage pipe, a second drainage pipe and a connecting head, wherein the first drainage pipe, the second drainage pipe and the connecting head are provided with meshing threads, and the first drainage pipe, the second drainage pipe and the connecting head are provided with rubber rings.

[0008] A further technical solution is that the inner side surfaces of the first drain pipe and the second drain pipe are provided with internal threads, and the outer side surface of the connecting head is provided with external threads matching with the internal threads.

[0009] A further technical solution is that the outer side surfaces of the first drain pipe and the second drain pipe are provided with external threads, and the inner side surface of the connecting head is provided with internal threads matching with the external threads.

[0010] A further technical solution is that a slot is provided on the outer surface of the connecting head, and an adjusting rod is connected to the slot.

[0011] This application has the following beneficial technical effects:

[0012] The connecting head is threadedly connected to the drain pipe and a rubber ring in the drain pipe is used to improve the installation convenience and sealing performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a schematic cross-sectional structure diagram of another embodiment of the present application.

[0015] Figure numerals: 1. first drain pipe; 2. second drain pipe; 3. connecting head; 4. rubber ring; 5. slot; 6. adjusting rod. DETAILED DESCRIPTION

[0016] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0017] The present application embodiment discloses a drainage pipe anti-seepage device. Figure 1 A drainage pipe anti-seepage device includes a first drainage pipe 1, a second drainage pipe 2 and a connecting head 3, wherein the first drainage pipe 1, the second drainage pipe 2 and the connecting head 3 are provided with meshing threads, and the first drainage pipe 1, the second drainage pipe 2 and the connecting head 3 are provided with a rubber ring 4.

[0018] In one embodiment, if Figure 1 As shown, the inner side surfaces of the first drain pipe 1 and the second drain pipe 2 are provided with internal threads, and the outer side surface of the connecting head 3 is provided with external threads matching with the internal threads.

[0019] In another embodiment, Figure 2 As shown, the outer side surfaces of the first drain pipe 1 and the second drain pipe 2 are provided with external threads, and the inner side surface of the connecting head 3 is provided with internal threads matching with the external threads.

[0020] Furthermore, a slot 5 is provided on the outer surface of the connecting head 3 , and an adjusting rod 6 is provided in the slot 5 .

[0021] Since the tube bodies of the first drain pipe 1 and the second drain pipe 2 are longer, the connecting head 3 can be threadedly connected to the first drain pipe 1 and the second drain pipe 2 by inserting the adjusting rod 6 into the slot 5 and rotating the connecting head 3 through the adjusting rod 6. The rubber ring 4 in the first drain pipe 1 and the second drain pipe 2 receives the extrusion force to improve the sealing performance.

[0022] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
