Abstract

[Problem] To provide a concave rectangular tube liftable storage rack in which the storage layers can be flexibly raised and lowered, the structure is simple, it is relatively stable, and the ease of use is improved. [Solution] The concave rectangular tube lifting storage rack includes multiple column assemblies, multiple assembly fixing members, and multiple storage layers. Each column assembly includes a concave rectangular tube and a long-hole fastener, each of which is assembled to a concave plate at a fixed distance from the other. One assembly fixing member is assembled at the upper and lower ends of each column assembly. Each storage layer includes a movable shelf and four second assembly members, each of which is located at one of the four corners of the movable shelf. Multiple movable storage layers are movable along the vertical direction. The four assembly members include multiple protruding columns, each of which engages with a locking hole in a long-hole fastener, and the storage layers are assembled between the column assemblies. The assembly members located at the upper and lower ends of each column assembly are attached to the outer surface of the corresponding assembly fixing member. [Selection Diagram] Figure 1

Description

This invention relates to a storage rack, and more particularly to a retractable storage rack with concave rectangular tubes in which the storage layers can be raised and lowered. A modular storage rack is a storage rack that is assembled from multiple independent components (storage layers, connecting components, etc.) and can be used for storage. The design of modular storage racks typically emphasizes flexibility and expandability, meeting the requirements of homes, offices, and other settings. Traditionally, there has been a distinction between round (round tube) and square (square tube) support columns. Using round tubes prevents horizontal assembly and effective expansion. Therefore, using square tubes is considered advantageous. However, conventional square tube and storage rack structures are relatively complex, require considerable assembly time, involve numerous production and packaging processes, and are costly. Furthermore, the inability to move storage layers vertically after fixing them to the square tubes makes them inconvenient to use.
