Description

Technical Field

[0001] This utility model relates to the field of doors and windows, specifically to a wear-resistant single-track lifting sliding door. Background Technology

[0002] In modern home and commercial space decoration, the choice of doors is crucial. Single-track lifting sliding doors are favored for their advantages such as space saving and flexible opening. However, the concave guide rail of traditional single-track lifting sliding doors has obvious drawbacks in actual use. It is very easy for dust to accumulate. Long-term dust accumulation not only affects the appearance, but also accelerates the wear and tear of the guide rail and pulley, greatly reducing the lifespan of the door and the user experience. Summary of the Invention

[0003] In view of the above, the purpose of this utility model is to address the problems of the prior art by providing a wear-resistant single-track lifting sliding door.

[0004] One type of wear-resistant single-track lifting sliding door in this solution includes a guide rail and a pulley. The guide rail has a raised arched cross-section structure, and the pulley contacts and cooperates with the guide rail.

[0005] Furthermore, the components include a door leaf, a base, and a connecting strip. The bottom sides of the door leaf are provided with edging extending towards the base. The surface of the base is provided with a guide rail mounting groove, and the guide rail is inserted into the mounting groove of the base by a plug-in method. The connecting strip is snapped into the inside of the edging and contacts and connects with the two sides of the base.

[0006] Furthermore, a self-lubricating structure is provided on the substrate.

[0007] Optionally, the self-lubricating structure includes at least one cotton core disposed at the top of the substrate and lubricating oil filled within the substrate.

[0008] Optionally, the self-lubricating component includes at least one groove provided at the top of the base, the groove being filled with lubricating oil and fitted with a cotton wick.

[0009] Optionally, self-lubricating includes at least one oiled cotton core inserted at the top of the base.

[0010] Compared with traditional single-track lifting sliding doors in the background technology, this solution has the following advantages:

[0011] Anti-dust and wear resistant: Traditional single-track lift-and-slide doors with concave guide rails are prone to dust accumulation, accelerating wear on the guide rails and pulleys. This solution uses a raised, arched cross-section structure for the guide rails, making it difficult for dust to remain on the surface; it will naturally slide off, greatly reducing wear caused by dust accumulation, significantly extending the service life of the guide rails, and enhancing the stability and durability of the entire single-track lift-and-slide door system.

[0012] Excellent dustproof effect: The bottom profile of the door leaf has edging on both sides that extends towards the base, covering the edge of the base to form a dustproof barrier, enhancing the sealing performance and further improving the dustproof effect.

[0013] It features a self-lubricating structure and offers various lubrication methods. Different lubrication methods can be flexibly selected according to the usage scenario and frequency, extending the service life of the equipment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] This embodiment of a wear-resistant single-track lifting sliding door includes a guide rail 1 and a pulley 2. The guide rail 1 has a raised, arched cross-section structure, and the pulley 2 contacts and engages with the guide rail 1. During daily use, because the surface of the guide rail 1 is raised, dust is difficult to accumulate on its surface and will naturally slide off due to gravity, greatly reducing wear caused by dust accumulation and significantly extending the service life of the guide rail 1. This, in turn, enhances the stability and durability of the entire single-track lifting sliding door system.

[0022] It also includes a door leaf 3, a base 4, and a connecting strip 5. The door leaf 3 is made of an aluminum alloy profile, high-strength engineering plastic, or metal frame, with edging extending towards the base 4 on both sides of its bottom profile, covering the edges of the base 4 to form a dust barrier. The base 4 is made of aluminum alloy profile, high-strength engineering plastic, or metal, and has a guide rail 1 mounting groove on its surface. The rail is inserted into the mounting groove of the base 4 by a plug-in method. The connecting strip 5 is snapped into the inside of the edging and contacts both sides of the base 4 to enhance sealing performance and improve dustproof effect. Example

[0023] This embodiment is based on embodiment two, with the entire guide rail 1 filled with lubricating oil and paired with a cotton core 6.

[0024] The guide rail 1 has a through-type oil cavity along its length, which is sealed at both ends by detachable sealing end caps, with silicone sealing rings embedded inside the end caps. The oil cavity is filled with lubricating oil, with a filling amount of 95%-100% of the oil cavity volume.

[0025] The guide rail 1 has spaced mounting holes at its top, into which cotton cores 6 are inserted. The cotton cores 6 are made of fiber cotton, extending from the bottom into the oil cavity, and the top protruding 1-2mm above the surface of the guide rail 1. The cotton cores 6 continuously absorb lubricating grease through capillary action, thus lubricating the pulley 2 as it passes. This design is suitable for high-frequency use in commercial settings. Example

[0026] This embodiment is based on embodiment one, with the guide rail 1 having an inner groove at the top filled with lubricating oil and a cotton core 6 installed.

[0027] The guide rail 1 has a longitudinal groove at its top. The groove has a convex cross-section, with a small upper opening and a large lower opening. The cotton core 6 is embedded in the small opening, and the lubricant is filled in the large opening. Example

[0028] This embodiment is based on embodiment one, and has an oil-impregnated cotton core 6 inserted at the top of the guide rail 1.

[0029] The guide rail 1 has a mounting hole at the top, into which a cotton core 6 is inserted and pre-soaked in lubricating oil. Lubricating oil can be applied directly to the cotton core 6 when replenishing lubricant.

[0030] Suitable for low-frequency use scenarios such as homes and balcony doors.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
