Description

Technical Field

[0001] The utility model relates to the technical field of office supplies, more specifically to a foldable file frame. Background Art

[0002] A file box is a commonly used file storage structure, which is used to hold various types of files and stationery, so that they stand neatly and beautifully on the desktop. Common file box types can be divided into three types: one-piece file boxes, assembled file boxes and folding file boxes. Among them, the one-piece file box is strong and durable, easy to use, but because it occupies a large space, it leads to high packaging and transportation costs. The assembled file box has low packaging and transportation costs, but requires consumers to assemble it by themselves, and the installation is complicated. Folding file boxes have the advantages of both one-piece file boxes and assembled file boxes, and currently occupy a mainstream position in the market. However, folding file boxes may be accidentally folded during use, resulting in unstable file box structure and affecting normal use. Some folding file boxes use independent fixings to fix and limit the file box after it is stretched out, so that the file box maintains a stable structure during use. The fixings not only increase the production cost of the file box, but also the fixings and file box are easily lost when stored separately.

[0003] In response to the above problems, a utility model patent with publication number: CN215501935U discloses a file frame, including at least two side panels, a back panel, a bottom panel, a back panel support rod, a bottom panel support rod and a snap structure. Specifically, the back panel and the bottom panel are arranged between adjacent side panels, each of the side panels has a horizontal side edge and a vertical side edge that are perpendicular to each other, the back panel and the bottom panel are respectively hinged to the side panels through the vertical side edges and the horizontal side edges, the back panel and the bottom panel can pivot relative to the side panels to realize the transformation of the file frame between a folded state and an open state. In the folded state, the back panel and the bottom panel are respectively abutted against the side panels in close parallel, and in the open state, the snap structure is arranged on the side panels, and the snap structure maintains the stability of the file frame by limiting the pivoting of the back panel and the bottom panel. However, this technical solution realizes the overall linkage of the structure through hinges and support rod structures, which has a relatively complex structure, high production requirements and production costs, and a small space between the side panels for applying force, making it more difficult for users to operate.
