Description

Technical fields:

[0001] This utility model relates to the field of bathroom technology, specifically a drain device that adapts to washbasins in multiple dimensions. Background technology:

[0002] When installing a basin drain, it's necessary to distinguish whether the basin has an overflow hole. Drains with overflow holes cannot be directly installed on basins without them, resulting in low product compatibility and causing inconvenience for users. Even some drains advertised as universally compatible often use a connector for drainage, resulting in larger product size and slower overflow flow. Utility model content:

[0003] The technical problem to be solved by this utility model is to provide a drain that is compatible with washbasins in multiple dimensions. The drain has a simple structure and is easy to install. It can be installed on washbasins that do not have overflow holes.

[0004] The technical solution of this utility model is to provide a multi-dimensional adaptable drain for washbasins, including a drain body, a water plug pressing core assembly, a flange, an upper sealing gasket, and a lower sealing gasket. The flange is sealed to the drain body through the upper and lower sealing gaskets. The water plug pressing core assembly is installed on the inner hole of the flange, and the drainage function is realized by opening and closing the water plug pressing core assembly. The flange includes a top annular end face and a cylindrical connecting section located below the end face. The outer circumference of the connecting section is provided with threads, which extend to the top of the connecting section. The upper part of the connecting section is provided with several overflow holes, and overflow hole baffles are correspondingly provided on the overflow holes. The shape of the overflow hole baffles is adapted to the overflow holes. The overflow hole baffles are connected to the connecting section through the connecting part to achieve the sealing of the overflow holes. The wall thickness of the connecting part is less than the wall thickness of the connecting section.

[0005] Preferably, several overflow holes are evenly spaced along the circumference of the connecting section.

[0006] Preferably, the overflow hole is square or round.

[0007] Preferably, the flange is made of plastic in one piece, with a wall thickness of 0.3-0.8mm for the connection part and 2-3mm for the connection section.

[0008] Preferably, the flange also has at least two grooves in the middle and lower parts, with the grooves spaced apart along the length of the connection section. When it is necessary to adapt to a thin basin, the flange connection section can be cut through these grooves to reduce its length.

[0009] Preferably, the groove has an external thread that is discontinuous with the connecting section, and this external thread has a complete start. The start is where the thread begins, avoiding direct cutting that would damage the thread and make it difficult to tighten during installation.

[0010] Preferably, the outer circumference of the drain body is provided with multiple vertically spaced recesses that fit the shape of a thumb. This allows for a more secure fit during installation, enabling installation by hand.

[0011] Preferably, two flat sections are symmetrically arranged on the outer circumference of the thread. This allows for easy installation and disassembly using tools.

[0012] Furthermore, the threaded end face at the lower end of the drain body has a flat end face with a reduced opening. This increases the sealing contact area during installation, making it more conducive to a sealed connection.

[0013] Compared with the prior art, the present invention has the following advantages after adopting the above solution:

[0014] This utility model has a simple structure and can be adapted to different basins. It can be easily installed regardless of whether there is an overflow hole. Attached image description:

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figure 1-4 As shown, a multi-dimensional adaptable drain for a washbasin includes a drain body 5, a water plug pressing core assembly 1, a flange 2, an upper sealing gasket 3, and a lower sealing gasket 4. The flange 2 is sealed to the drain body 1 through the upper sealing gasket 3 and the lower sealing gasket 4. The water plug pressing core assembly 1 is installed on the inner hole of the flange 2, and the drainage function is realized by opening and closing the water plug pressing core assembly 1. As an improved structure, the flange 2 includes a top annular end face and a cylindrical connecting section 21 located below the end face. The outer circumference of the connecting section 21 is provided with threads, and the threads extend... Extending to the top of the connecting section 21 to meet the installation requirements of various basins; the upper part of the connecting section 21 is provided with several overflow holes, and an overflow hole baffle 22 is provided at the overflow hole. The shape of the overflow hole baffle 22 is adapted to the overflow hole and is slightly smaller than the size of the overflow hole. The overflow hole baffle 22 is connected to the connecting section 21 through a connecting part 23 around the overflow hole to block the overflow hole. The wall thickness of the connecting part 23 is less than the wall thickness of the connecting section 21, so that the overflow hole baffle 22 can be punctured when an overflow hole is needed.

[0021] In this embodiment, there are three overflow holes, which are square in shape and evenly spaced along the circumference of the connecting section. Correspondingly, three overflow hole baffles are integrally made of plastic during flange processing. The overflow hole baffles 22 seal the overflow hole positions. The wall thickness of the connecting part 23 is 0.4mm, and the wall thickness of the connecting section 21 is 3mm. In this way, a thin connection is formed between the overflow hole baffles 22 and the connecting section 21 of the flange. When in use, since the overflow hole baffles 22 are not open, the product can be directly used for basins without overflow holes. When it is necessary to use it for basins with overflow holes, simply poke the overflow hole baffles 22 with a little force, and the connecting part 23 will break, and the overflow hole baffles 22 will fall off. At this time, the overflow hole at the corresponding position can be formed, which satisfies the installation requirements.

[0022] As a preferred method, to better adapt to various thin-walled basins, the flange 2 is provided with at least two grooves 25 in the middle and lower parts. The grooves 25 are arranged along the circumferential wall of the connecting section 21. In this embodiment, two grooves 25 are provided, spaced apart along the length of the connecting section. One groove is located at the lower one-third of the length of the connecting section, and the other is located at the lower two-thirds. Considering that cutting the groove would damage the threads of the connecting section, thus affecting the tightening during installation, the groove 25 has an external thread that is discontinuous with the threads of the connecting section 21. This external thread can be relatively small, with a complete start point, avoiding direct cutting that would damage the threads and make tightening difficult during installation. Thus, when the basin is thin and the drain body 5 cannot be tightened, the worker can cut it from the groove 25 according to the length to meet the installation requirements without affecting the integrity of the threads and making installation difficult.

[0023] As a preferred method, the outer circumference of the drain body 5 is provided with multiple vertically arranged recesses at even intervals. The recesses fit the contour of the thumb, allowing for a better fit and force application during installation, making it easier to install by hand.

[0024] As a preferred embodiment, the drain body 5 has two symmetrically arranged flat positions on the outer circle of the thread, which facilitates installation and disassembly using tools. Furthermore, the lower threaded end face of the drain body 5 has a flat end face with a constriction, which increases the sealing contact surface during installation and is more conducive to connection and sealing.

[0025] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent structural or procedural modifications made using this specification are included within the patent protection scope of this invention.
