Paper pressing board for folder

Abstract

The invention discloses a paper pressing board for folder, which comprises a bottom board, elastic steel wires and a rotating arm-type switch, wherein the two elastic wires are arranged at the bottom or the inner cavity of the bottom board in a penetrative manner, one side of the rotating arm-type switch is provided with a control part which facilitates the operation of users on the outer side of the bottom board and which extends to the outer side of the bottom board; since the two elastic steel wires are driven by the rotating arm-type switch according to the invention, the paper pressing board achieves simple structure, smaller thickness and volume and smaller occupied space, the folder with the paper pressing board of the invention can clamp more paper, the operations of clamping and unclamping are performed on the side of the bottom board so as to bring better convenience to operation and avoid the hindrance of folder hooked loop and other components, the total thickness of the paper pressing board is not changed during clamping and unclamping, in addition, the paper pressing board is smaller in thickness, lighter and thinner, and especially, can be used for the folder with small hooked loops.

Description

technical field [0001] The invention relates to the technical field of paper pressing boards for file folders, in particular to a paper pressing board used for small hook-and-loop folders. Background technique [0002] In the prior art, the file folder is equipped with a press board, which is used to fix the paper, and the press board is used to keep the paper on the file folder. Folders are divided into large hook and loop folders and small hook and loop folders according to the height or inner diameter of the hook and loop. The height or inner diameter of the hook and ring is less than 35mm. Large hook and loop folder. [0003] Because the paper storage space of the small hook-and-loop folder is small, the platen used for the small hook-and-loop folder is a sheet-type push plate with clip holes 14, such as figure 1 As shown, when this kind of pressboard is clamped on the hook, the user needs to forcefully push the pressboard horizontally, so that the clamping hole 14 is ...

AI Technical Summary

Problems solved by technology

[0003] Because the paper storage space of the small hook-and-loop folder is small, the platen used for the small hook-and-loop folder is a sheet-type push plate with clip holes 14, such as figure 1 As shown, when this kind of pressboard is clamped on the hook, the user needs to forcefully push the pressboard horizontally, so that the clamping hole 14 is clamped on the needle body of the hook, and the resistance that exists when pushing the pressboard is relatively large. The cardboard is laborious and inconvenient to operate, and the friction between the cardboard and the document will tear the paper, and the cardboard will damage the document, causing trouble to the user

[0004] There are mainly two types of pressboards suitable for large hook-and-loop folders. The first pressboard is shown in the Chinese patent with the patent publication number "CN1367088A" and the patent name "pressing and perforating device". The pressboard includes a bottom plate , two elastic steel wires and a pressing handle 13, the elastic steel wires are arranged on the bottom plate, one side of the pressing handle 13 is provided with a pressing part, and the other side of the pressing handle 13 is provided with a clamping part for clamping the elastic steel wire, and the pressing handle 13 The fulcrum of the clamping rotation is against the top surface of the bottom plate, and the pressing handle 13 moves in a plane perpendicular to the top surface of the bottom plate. The pressing handles 13 all protrude above the bottom plate. The thickness of the pressing board is relatively large, and the pressing board occupies a large space. , reduce the amount of paper clamping in the file folder, and after the pressure plate is unclamped, one end of the pressing handle 13 is tilted up, such as figure 2 As shown, the total thickness of the pressboard after opening the folder increases by one to three times, which takes up a lot of space, and it is difficult to turn the pages of the paper clamped on the folder, which also limits the amount of paper clamped by the folder

The total thickness of this kind of pressboard after opening the clip reaches 20-30mm, but the height of the small hook-and-loop folder is not higher than 35mm, so this kind of pressboard cannot be used for small hook-and-loop folders

[0005] The second type of pressboard is shown in the Chinese patent whose patent publication number is "CN1262176A" and the patent name is "pressing clip for file folder". Spring steel wire, since the cam part is set on the top surface of the bottom plate, the overall thickness of the entire press plate is still too large, and this type of press plate is not suitable for small hook and loop folders

In addition, this kind of pressboard is inconvenient to use. When opening and closing the clamp, the cam piece protruding from the top surface of the bottom plate needs to be rotated. The top surface of the bottom plate needs sufficient operating space, otherwise the cam piece will be damaged when operating the cam piece. Obstructed by folders, hooks and other components, to sum up, this kind of pressboard cannot be used for small hook and loop folders. Therefore, the pressboard of the prior art needs to be changed
