AI Technical Summary
The existing panoramic narrow-bezel sliding doors have inconsistent colors and exposed drainage covers at the machining holes, which affects the aesthetics and makes them prone to water accumulation.
Design a concealed drainage channel cover made of aluminum alloy. The top of the drain outlet is 4mm and the bottom is 7mm. The cover body has a sunken structure, and the drainage holes are set on both sides of the drain outlet to avoid exposing the machining holes. The sunken structure prevents water accumulation.
This solves the problem of inconsistent hole colors affecting aesthetics, while also preventing water accumulation and improving overall aesthetics and functionality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of doors and windows, specifically a concealed drainage channel cover. Background Technology
[0002] In today's world of abundant material wealth, minimalism advocates thrift, avoidance of waste, and a return to nature. Narrow-frame sliding doors can be characterized by minimalist shapes, designs, and configurations, emphasizing simplicity and restraint. In modern fashion, they primarily showcase a simple and unpretentious charm through clean lines, offering advantages such as a wide field of vision and a simple style. Paired with elegant jazz black, ceramic gray, starlight gray, and classic brushed finishes, they are quite popular among young people. As a result, narrow-frame profiles have become a flagship product for many door and window manufacturers. As young people grow up, their aesthetic values and design concepts increase, leading to higher demands for narrow-frame doors and windows, requiring them to be more slender and beautiful while maintaining performance.
[0003] Existing panoramic narrow-bezel sliding door drainage covers, which use aluminum alloy profiles for milling holes, damage the surface color of the profiles, resulting in a mismatch between the color of the machined holes and the surface color of the drainage cover. At the same time, the machined holes are directly exposed, affecting the aesthetics. Therefore, in view of the above situation, there is an urgent need to develop a hidden drainage channel cover to overcome the shortcomings in current practical applications. Utility Model Content
[0004] The purpose of this invention is to provide a concealed drainage channel cover to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A concealed drainage channel cover includes: a cover body, a drainage hole and a water outlet. The cover body has a sunken structure, with a water outlet provided on the inner side of the sunken part, and drainage holes connected to the water outlets are provided on both sides of the shell wall of the sunken part.
[0007] As a further embodiment of this utility model: the top of the water outlet is 4mm and the bottom is 7mm.
[0008] As a further embodiment of this utility model, the cover body is made of aluminum alloy.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] This concealed drainage cover has a 4mm top diameter for the drain outlet, and the finished drainage holes are located on both sides of the drain outlet. As a result, the bottom processing holes are not visible from the front, and there is no mismatch between the color of the processing holes and the color of the cover itself. This makes the overall appearance more aesthetically pleasing. At the same time, the recessed structure can prevent water accumulation on the surface. Attached Figure Description

[0015] The technical solution of this application will be further described in detail below with reference to specific embodiments.
[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0017] Please see Figure 1 In one embodiment of the present invention, a hidden drainage channel cover includes: a cover body 1, a drainage hole 2 and a water outlet 3. The cover body 1 has a sunken structure, and a water outlet 3 is provided on the inner side of the sunken part. Drainage holes 2 connected to the water outlet 3 are provided on both sides of the shell wall of the sunken part.
[0018] In one embodiment of this utility model, the top of the water outlet 3 is 4mm and the bottom is 7mm.
[0019] In one embodiment of this utility model, the cap body 1 is made of aluminum alloy.
[0020] The concealed drainage channel cover has a 4mm top at the outlet 3, and the finished drainage holes 2 are on both sides of the outlet 3, so the bottom processing holes are not visible from the front. This avoids the situation where the color of the processing hole is inconsistent with the color of the cover body 1, making the overall appearance more aesthetically pleasing. At the same time, the sunken structure can prevent water accumulation on the surface.
[0021] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
