Description

Guide's work file

Technical Field

The invention relates to the field of travel equipment supplies, in particular to a guide work folder.

Background

The guide usually needs to use a folder in work for storing various documents in the travel, such as tourist site introduction documents, travel notes, invoices, tourist information documents, and the like. A conventional folder structure in the prior art is shown in fig. 1 and 2, and includes a front cover 1, a spine cover 3, and a rear cover 2 separated from each other by a folding line, and a bar-shaped spring clip 4 is disposed on the inner side of the rear cover 2, and aligns the left side of a document when clamping the document, and then presses the bar-shaped spring clip 4 against the left side of the document.

However, the pressing force of the strip-shaped spring clamp 4 with the structure is fixed, the size of the pressing force cannot be adjusted according to the thickness of the file, and when the file is thick, the pressing force applied to the file is large, so that the file can be crushed.

In addition, when a plurality of files are stored many times, the sizes of different files are different, when the files with different sizes are stored, the upper left corners of the files are generally aligned to be clamped and stored, the total thickness of the files at the upper left corners is larger, the total thickness of the files at the lower left corners is smaller, and thus when the strip-shaped spring clamps 4 in the prior art are used for clamping, the clamping force applied to the upper left corners of the files is larger, the clamping force applied to the lower left corners is smaller, the lower left corners of the files are not clamped at all, and therefore the file clamping effect is poor.

Disclosure of Invention

The invention aims to provide a guide working folder, which can adjust the clamping force on files according to the thickness of the files and avoid the situation that the files are damaged due to over-thick files.

In order to achieve the purpose, the invention adopts the following technical scheme:

a guide work file comprises a front cover, a ridge cover and a rear cover, wherein the ridge cover is arranged in a hollow mode, a clamping mechanism is arranged in the ridge cover, and the clamping mechanism comprises an elliptical shaft and two lever type pressing pieces, wherein the elliptical shaft is rotatably connected in the ridge cover; the elliptical shaft extends along the length direction of the ridge cover and comprises a first section and a second section which can rotate mutually; two lever compressing pieces are distributed along the length direction of the ridge cover, one end of each lever compressing piece is respectively propped against the outer edges of the first section and the second section of the elliptical shaft, and the other end of each lever compressing piece extends out of the ridge cover and is in contact with the inner side of the back cover.

The principle of the scheme is as follows:

the specific principle of the clamping mechanism for clamping the file is as follows: the elliptical shaft is used for driving the two lever type pressing pieces to rotate, one end of each lever type pressing piece abuts against the outer edge of the elliptical shaft, when the elliptical shaft abuts against the lever type pressing pieces from the short diameter end to the long diameter end and then rotates to abut against the lever type pressing pieces, one end of each lever type pressing piece, which is in contact with the inner side of the rear cover, is driven to be close to or far away from the inner side of the rear cover, and therefore the fact that the lever type pressing pieces clamp or loosen files is achieved.

This scheme of adoption can reach following technological effect:

1. clamping mechanism adopts the structure of elliptical shaft cooperation lever compressing tablet, can adjust lever compressing tablet pivoted angle through the rotatory angle of elliptical shaft to adjust the lever compressing tablet and to the clamp force size of file, with the centre gripping that compresses tightly that is applicable to different thickness files, avoid leading to the file to be pressed from both sides the condition of damaging because of the file is too thick.

2. Improve the centre gripping mode of traditional whole section bar spring clamp for the mode of two segmentation centre grippings, its effect has one: firstly, when files with different sizes are stored, the rotating angles of the first section and the second section of the elliptical shaft can be selected according to the difference between the thicknesses of the upper left corner and the lower left corner of the stored files, so that the upper left corner and the lower left corner of the stored files can bear proper clamping force, and therefore the invention is particularly suitable for storing the files with different sizes; secondly, when some files need to be taken out, if the bar-shaped spring clamp in the prior art is adopted for clamping, the bar-shaped spring clamp needs to be loosened firstly, then the needed files are taken out, all the files are not clamped at this time, after part of the files are taken out, the rest files are easily disordered, at this time, the files need to be rearranged and then are pressed by the bar-shaped spring clamp, the process is troublesome, and a sectional type clamping mode is adopted, one lever-type pressing sheet can be loosened firstly, so that one corner of the files is loosened, one corner of the needed files is taken out, then one corner of the rest files is clamped by the lever-type pressing sheet, the other corner of the needed files is taken out in the same mode, and the rest files do not need to be rearranged again.

Further, the lever type pressing piece comprises a lever connected to the ridge cover in a rotating mode and a pressing piece body connected to the lever in a sliding mode, driving teeth are arranged on the outer edge of the elliptical shaft, and driven teeth meshed with the driving teeth are arranged on the lever type pressing piece. When the elliptical shaft rotates, the pressing sheet body is driven to slide on the lever through the meshing action of the driving tooth and the driven tooth and rotate along with the pressing sheet, therefore, the compressing sheet moves towards the direction far away from the side edge of the file while loosening the compression on the file, people can quickly search for the required file by turning the upper left corner of the file at the moment, the file searching device is particularly suitable for searching for the files when the files with different sizes are stored, because the upper left corners of the files are aligned to store when storing the files with different sizes, if the left sides of the files are clamped and pressed by the traditional strip-shaped spring clamps, when people search the needed files, the files are required to be turned up in turn, in the scheme, the compressing sheet at the upper left corner is far away from the side edge of the file, and the compressing sheet at the lower right corner clamps the file, so that people only need to turn over the upper left corner of the file, and the required file is more convenient to find.

Further, the outer end of the first section of elliptical shaft and the outer end of second section all are coaxially fixed with the back shaft, and the back shaft rotates to be connected and covers at the ridge, and outside the back shaft outer end all stretched out the ridge lid, and the outer end of back shaft all was equipped with the knob. The knob is convenient for screwing the supporting shaft, so that the first section and the second section of the elliptical shaft are driven to rotate.

Furthermore, a rubber pressing block is arranged at the contact end of the lever type pressing sheet and the inner side of the rear cover. The rubber pressing block is in contact with the upper surface of the file, so that the file is not easy to crush.

Furthermore, two corners of the outer side of the rear cover are respectively provided with an elastic belt, and the two elastic belts are distributed in a splayed shape. The file can be closed by pulling two elastic bands onto two corners of the front cover.
