Description

Technical Field

[0001] The utility model relates to the technical field of drainers, in particular to a washbasin drainer. Background Art

[0002] A drainer is a commonly installed drainage device in basins such as sink basins and washbasins in buildings.

[0003] When designing existing drainers, sealing rings are often provided on both the upper and lower sides of the washbasin to enhance the sealing effect and prevent water leakage. However, this design brings certain inconveniences during the actual installation process. Specifically, the upper and lower sealing rings in the drainer have different structures and their specific usage positions. If the positions of these two sealing rings are interchanged incorrectly during installation, it may lead to poor sealing and thus cause water leakage problems. This design not only increases the installation difficulty but also may cause problems during use due to improper installation, bringing unnecessary troubles and losses to users. For example, if the lower gasket is not placed flat, it will cause poor extrusion and water leakage during installation. In addition, there is also the problem of losing the gasket during installation in reality. Especially for online shopping users, small accessories are often lost, resulting in the inability to install and the need to purchase or mail the gasket separately.

[0004] Therefore, the present application proposes a drainer to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a washbasin drainer, which solves the technical problems raised in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A washbasin drainer includes a corrugated pipe. The upper end of the corrugated pipe is connected with a cleaning pipe. A cleaning port is opened on the side wall of the cleaning pipe. The upper end of the cleaning pipe is provided with a lower connection mechanism, and the upper end of the lower connection mechanism is provided with an upper connection mechanism;

[0007] The lower connection mechanism includes a lower connection pipe. An anti-slip sleeve is sleeved outside the lower connection pipe. The upper end of the lower connection pipe is provided with a sealing layer. The sealing layer is annular. The anti-slip sleeve and the sealing layer are an integral body;

[0008] The upper connection mechanism includes a threaded connection pipe. The threaded connection pipe is threadedly connected with the lower connection pipe. The upper end of the threaded connection pipe is fixedly connected with an upper abutting ring. A plugging plate is arranged inside the threaded connection pipe. An annular upper sealing gasket is sleeved on the threaded connection pipe. The upper sealing gasket is made of elastic plastic. The inner diameter size of the upper sealing gasket is smaller than the outer diameter size of the threaded connection pipe.

[0009] Preferably, the lower connection pipe is wrapped by the anti-slip sleeve and the sealing layer, and the materials of the anti-slip sleeve and the sealing layer are elastic plastic.

[0010] Preferably, a plurality of anti-slip protrusions are provided on the outer side wall of the anti-slip sleeve.

[0011] Compared with the related art, a washbasin drain provided by the present utility model has the following beneficial effects:

[0012] The present utility model provides a drain, and the anti-slip sleeve and the sealing layer are integrated. This design simplifies the structure, enabling the sealing layer to directly serve as the sealing gasket in the lower layer position, thereby reducing the number of sealing parts used; since there is only an upper sealing gasket in this design, its position is more definite and it has been fixed at a specific installation position through a small inner diameter design. When installing, the user only needs to tighten it, without having to find the upper sealing gasket or consider the placement position of the upper sealing gasket, reducing the installation difficulty and making the installation process simpler and faster.
