Description

Technical Field

[0001] The utility model relates to the technical field of stationery, in particular to a file folder with adjustable storage space. Background Art

[0002] As a file folder, there is a file folder in which a front cover sheet and a back cover sheet are connected so as to be openable and closable, and a storage section is provided between the two sheets. This file folder can store notebooks, printed materials, etc. in the storage section.

[0003] However, the existing storage space is basically fixed. If the file material is larger than the storage space, the folder cannot be closed, that is, the file material in the folder cannot be protected; if the file material is smaller than the storage space, that is, there is a gap between the cover sheet and the file material, when stacked, the folder is easily deformed or even damaged when the weight is applied, and one end of the cover sheet is supported by a connecting part, and there is a gap between the cover sheet and the file material, which easily produces an inclined slope, resulting in multiple folders cannot be neatly stacked; so suitable folders are selected for file materials that need to be of suitable thickness. For this reason, it is necessary to purchase multiple specifications when purchasing, and at the same time, when the folder is used for the second time, it is necessary to re-evaluate the compatibility between the file material and the folder, which increases the workload of users. For this reason, a folder with adjustable storage space is now developed. Utility Model Content

[0004] The utility model aims to provide a file folder with adjustable storage space, which has the advantage of simple structure and solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a folder with adjustable storage space, comprising a back cover sheet, a folding rubber strip and a cover sheet, wherein one end of the folding rubber strip is connected to the back cover sheet, and the other end of the folding rubber strip is connected to the cover sheet, the back cover sheet, the folding rubber strip and the cover sheet form a hinge structure, and the cross-sectional view of the folding rubber strip is in the shape of a wavy line.

[0006] Preferably, a clamp is provided on the back cover sheet, and the clamp is close to one side of the folded rubber strip.

[0007] Preferably, the clamp is a concentric quick-release clamp, and the cover sheet is provided with a hole for the concentric quick-release clamp to pass through.

[0008] Preferably, both ends of the clamp are provided with limiting parts, and the cover sheet is provided with notches matched with the positions of the limiting parts.

[0009] Preferably, a limiting blade is provided on the inner end surface of the cover sheet.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model provides a folding rubber strip, which can increase the distance between the cover sheet and the back cover sheet through deformation, thereby achieving the effect of adjusting the storage space to adapt to file materials of different thicknesses. At the same time, the cover sheet and the back cover sheet can be fit flush with the file material, and the user does not need to consider the compatibility of the folder and the file material. The file material is better protected, the service life of the folder is increased, and multiple folders can be neatly stacked. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 for Figure 1 A partial enlarged view of point A in the middle. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1 to Figure 2 , The utility model provides an embodiment: a folder with adjustable storage space, including a back cover sheet 1, a folding adhesive strip 2 and a front cover sheet 3, one end of the folding adhesive strip 2 is connected to the back cover sheet 1, and the other end of the folding adhesive strip 2 is connected to the front cover sheet 3, and the back cover sheet 1, the folding adhesive strip 2 and the front cover sheet 3 are sequentially connected to form a hinge structure, and the document material can be stored between the back cover sheet 1 and the front cover sheet 3. The cross-sectional view of the folding adhesive strip 2 is in the shape of a wavy line. The folding adhesive strip can increase the distance between the front cover sheet 3 and the back cover sheet 1 through deformation, so as to achieve the effect of adjusting the storage space to adapt to document materials of different thicknesses. At the same time, the front cover sheet 3 and the back cover sheet 1 can be made to fit flush with the document material, and the user does not need to consider the adaptability of the folder and the document material, so as to better protect the document material, improve the service life of the folder, and realize that multiple folders can be neatly stacked. .

[0016] A clamp 4 is provided on the back cover sheet 1, and the clamp 4 is close to one side of the folding rubber strip 2. The clamp 4 is used to clamp and fix a single sheet or multiple sheets of paper materials so that they are neatly stored and firmly connected to the folder.

[0017] In this embodiment, the clamp 4 is a three-hole concentric quick-release clamp. After punching a single or multiple sheets of paper, the clamp 4 is installed in conjunction with the folder. The cover sheet 3 is provided with a hole 5 for the concentric quick-release clamp to pass through. The hole 5 avoids the clamp 4 to prevent the cover sheet 3 from being unable to cover.
