Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer folders, in particular to a detachable multi-layer folder. Background Art

[0002] Folders are stationery used to hold paper documents. Most of the folders we use now are plastic products. Using plastic materials is not only costly but also not environmentally friendly. In addition, since most plastic folders are one-piece molded, their shape is fixed when they leave the factory, which is not conducive to the transportation of the product. When the folders are not in use, they take up a relatively large space.

[0003] In order to solve the above technical problems, the Chinese patent with publication number CN203041294U in the prior art discloses a detachable multi-layer folder, the technical points of which are: it includes at least two folder components, each folder component is provided with at least three sockets, and the sockets of adjacent folder components are fixedly connected by pins; the folder component includes a bottom plate, a first side plate, a second side plate, a baffle, a first triangular plate, a second triangular plate, a third triangular plate and a fourth triangular plate, one side of the baffle is pivotally connected to a right angle side of the first triangular plate, and the other side is pivotally connected to a right angle side of the third triangular plate, the hypotenuse of the first triangular plate is pivotally connected to the hypotenuse of the second triangular plate, the hypotenuse of the third triangular plate is pivotally connected to the hypotenuse of the fourth triangular plate, the second triangular plate is glued and fixed to the first side plate, the fourth triangular plate is glued and fixed to the second side plate, the first side plate is pivotally connected to one side of the bottom plate, the second side plate is pivotally connected to the other side of the bottom plate, and the baffle is pivotally connected to the bottom plate.

[0004] The number of layers in the above application can be selected as needed; the structure is simple and easy to assemble and disassemble, but the existing technical solution has the following shortcomings: the above solution lacks components for fixing files, and also lacks the functionality of the structure. Since it is an integrated structure, the functionality is relatively single. When using the folder, it is not convenient to quickly view the files placed inside the folder. Utility Model Content

[0005] Technical problems solved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a detachable multi-layer file folder, which can effectively solve the problems of the prior art such as the lack of fixed parts and relatively single functionality.

[0010] Furthermore, both sides of the bottom bar begin to have circular groove structures, the side panels are T-shaped panel structures, and the rotating rod is fixed to the bottom end of the T-shaped side panels.

[0011] Furthermore, an outer strip is fixed to the front of the file shell on one side, and a docking strip is fixed to the front of the file shell on the other side. The inner diameter of the outer strip is matched with the outer diameter of the docking strip, and both the outer strip and the docking strip are soft rubber strips.

[0012] Furthermore, the positioning piece is a soft leather structure, and the file cover is made of waterproof material, and the positions of the groove body and the positioning piece correspond.

[0013] Furthermore, the spring pieces and the abutment plates are arranged in multiple groups at equal intervals on the positioning plate, and the spring pieces and the abutment plates are staggered. One end of the spring piece is fixed to the bottom of the positioning plate, and the spring piece is an elastic spring structure.

[0014] Furthermore, the clamping tube is a hollow tubular structure with no surface at both ends, and a vertical groove is provided through the middle of the clamping tube.

[0015] Beneficial effects

Afterwards, multiple groups of elastic sheet structures can clamp multiple document papers and be combined with the external side plate and the positioning plate into one. Then, the rotating rod structure with the positioning plate in the side plate is clamped with the circular groove in the bottom strip, so that the other end of the document paper can be clamped in the clamping tube. The document paper is stably connected through the contraction effect of the clamping tube, so that the positioning frame structure with the document paper can be connected and fixed with the document shell structure. When connecting, the outer strip and the docking strip on the outside can be matched and docked, and then the document shell on one side can be matched and buckled with the document shell on the other side, and the positioning piece on one side can be matched and clamped with the groove body, and then it can be fixed and clamped with the sub-button and the female buckle to fix the document paper in the two groups of document shells to achieve fixed closure.

[0018] In this device, through the positioning frame structure, the user can directly take out the positioning frame from the two sets of file shells, so when in use, it can be disassembled and assembled according to the needs of use, and the document paper is clamped by the spring and the abutment structure to play the function of connection and portability. At the same time, the user can also realize the combined function by locking the rotating rod structure and the circular groove of the bottom bar. BRIEF DESCRIPTION OF THE DRAWINGS
