Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, specifically a lower track profile mechanism. Background Technology

[0002] Authorization announcement number CN221053489U, entitled "A Lower Rail Profile Structure," includes a profile body in the shape of a "C." The profile body has a cavity on its left side, a pulley guide groove on its top right side, and a water guide section on its bottom right side. The left and right sides of the pulley guide groove are inclined to prevent the pulley from detaching. The water guide section slopes downwards from the left side of the profile body towards the right. The pulley guide groove on the top right side of the profile body, with its inclined left and right sides, prevents the pulley from detaching from the lower rail profile. Additionally, the water guide section, sloped downwards from the left side of the profile body towards the right, utilizes drainage characteristics to discharge shower water outside the lower rail.

[0003] The applicant believes the following defects exist: 1. The bottom of the lower rail profile is flat, which results in insufficient rigidity and makes it prone to deformation during long-term use;

[0004] The cover plate is small and there is a gap between it and the water guide, which makes it easy for water to flow into the screw receiving groove through the gap, causing the screw to rust.

[0005] Because of the different pulley structure models, the lower rail profile cannot be replaced according to the pulley structure model, thus reducing its applicability;

[0006] Therefore, we invented a lower rail profile mechanism. Summary of the Invention

[0007] The purpose of this utility model is to provide a lower rail profile mechanism to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A lower rail profile mechanism includes a profile body, the profile body being "C" shaped, the bottom of the profile body having an inwardly concave arched groove, the top of the profile body having an inclined surface from left to right, and the top of the inner wall of the profile body having a pulley guide groove.

[0010] In a preferred embodiment of this utility model, the profile body is composed of a main profile and an auxiliary profile. Both the main profile and the auxiliary profile are "C" shaped. The left end of the auxiliary profile is attached to the right end of the main profile, and the top of the inner wall of the auxiliary profile is provided with a pulley guide groove.

[0011] In a preferred embodiment of the present invention, a screw receiving groove is formed between the top right side of the main profile and the bottom right side of the auxiliary profile, and an inclined surface two is provided on the right side of the inner wall of the auxiliary profile.

[0012] In a preferred embodiment of this utility model, a screw connection position one is provided in the middle of the right side of the main profile, and a screw connection position two is provided in the middle of the right side of the auxiliary profile.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] The bottom of the profile body is provided with an inwardly recessed arched groove, which improves the strength of the profile body.

[0015] The profile body consists of a main profile and an auxiliary profile, both of which are "C" shaped. The left end of the auxiliary profile is attached to the right end of the main profile. The profile body is designed as a detachable structure, with pulley guide grooves set on the auxiliary profiles. The auxiliary profiles are fixed to the main profiles with screws, which facilitates the disassembly of the auxiliary profiles and allows for the replacement of different models of pulley guide grooves, improving the utilization rate of the profile body. In addition, the auxiliary profiles are close to the main profiles, and a screw receiving groove is formed between them, preventing water from directly entering the screw receiving groove.
