Abstract

The utility model discloses a curl-proof book cover clamp, belonging to the technical field of the file clamp group without a clamp of the index tool subclass in the file card in the file clamp in the casual binding of single sheet of the special type printed matter big class in the file clamp in the atlas in the binding of the printing branch of the ministry of transport of the operation according to the International Patent Classification (IPC). The curl-proof book cover clamp aims to solve the technical problem that only the upper edge is fixed by the original book cover clamp, and the lower edge two angles are easy to be curled, comprising a clamp strip, a clamp surface, a right included angle, a left included angle, and an included angle. The curl-proof book cover clamp is characterized in that: the side surface of the long edge of the right included angle is stuck on the right lower angle of the clamp surface; the side surface of the long side of the left included angle is stuck on the left lower angle of the clamp surface; the curl-proof book cover clamp has simple manufacturing, low cost, and convenient use.

Description

The Anti-rolling book cover folder

(1) technical field:

The utility model relates to the Anti-rolling book cover folder, divides to belong to operation Department of Transportation printing branch, bookbinding by International Patent Classification (IPC) (IPC); Atlas; File; The big class of special presswork, the interim bookbinding of single page; File; The file card; Retrieve the apparatus group, do not have the technical field of the file group of binding clasp.

(2) background technology:

At present, the technology about the file that do not have binding clasp existing and that once had was all done very fruitful effort to the demand of Anti-rolling book cover folder, also once designed many outstanding technical schemes.As being declared by Liu Zhong of the Decree of Patent Office of China in 1996, Granted publication number is CN2224086Y, and China Patent No. (ZL) is: numbers 95212810.1 utility model patent title is the utility model patent of " Convenient book clip ", the technical scheme that is adopted.The technical elements that does not have the file of binding clasp is a routine of great value invention, and it has solved book clamp technical problem easily effectively.But still have some deficits only fixedly top but the technical problem of following two easy crimpings in angle of Book cover clip before its also be difficult to solve.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of Anti-rolling book cover folder.With Book cover clip before solving only fixedly top but the technical problem of following two easy crimpings in angle.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: Anti-rolling book cover folder of the present utility model mainly is made of clamp bar, bark pocket, right angle, left angle, angle.

In shape, structure and combination thereof, Anti-rolling book cover folder of the present utility model with the essential features that immediate prior art has is: the groove location of clamp bar is inserted in the upper marginal position that is installed in bark pocket, the interior location of bark pocket is inserted in the upper marginal position at books, be combined into the bascule of nested shape, function has been the effect of fixing top edge originally.In shape, structure and combination thereof, the Anti-rolling book cover folder of the present utility model technical characterictic different with immediate prior art is: the bonding position, the lower right corner that is connected bark pocket, the long side face position of right angle, the bonding position, the lower left corner that is connected bark pocket, long side face position of left side angle, be combined into the fixed structure of rib vertebra shape, function has been to be inserted in the effect that the book angle prevents book angle volume wrinkle.So just reached the only fixing purpose of the technical problem of top but following two easy crimpings in angle of Book cover clip before the solution of Anti-rolling book cover of the present utility model folder.

The beneficial effect of the Anti-rolling book cover of utility model folder is: the utility model be before the solution Book cover clip only fixedly the technical scheme that technical problem adopted of top but following two easy crimpings in angle compared an advantage and improvement with existing with the technology that once had about the file group that do not have binding clasp:

First, owing to designed the bonding position, the lower right corner that is connected bark pocket, long side face position of right angle in the technical scheme of Anti-rolling book cover folder of the present utility model, the bonding position, the lower left corner that is connected bark pocket, long side face position of left side angle, be combined into the fixed structure of rib vertebra shape, so can easier solution can be inserted in the technical problem that the book angle prevents book angle volume wrinkle.

Accompanying drawing provides the structural representation of Anti-rolling book cover folder of the present utility model:

Fig. 1: the overall structure schematic diagram that is Anti-rolling book cover folder of the present utility model;

Fig. 2: the part one corner structure schematic diagram that is Anti-rolling book cover folder of the present utility model;

The label declaration at each position in the schematic diagram:

1 clamp bar, 2 bark pockets, 3 right angle 4 left angle 5 angles

(5) specific embodiment:

Below in conjunction with accompanying drawing, to Anti-rolling book cover of the present utility model folder for Book cover clip before realizing solving only fixedly top but the optimal way of the technical scheme that the technical problem of following two easy crimpings in angle is taked be described further:

Its static structure: see also accompanying drawing: as shown in the figure, Anti-rolling book cover folder of the present utility model mainly is made of clamp bar 1, bark pocket 2, right angle 3, left angle 4, angle 5.Its major part clamp bar 1, bark pocket 2 are selected for use by market.Its right angle 3 is rib vertebra shapes, is material to mould firmly, through the processing and forming manufacturing.Its left angle 4 is rib vertebra shapes, is material to mould firmly, through the processing and forming manufacturing.

In shape, structure and combination thereof, Anti-rolling book cover folder of the present utility model with the essential features that immediate prior art has is: the groove location of clamp bar 1 is inserted in the upper marginal position that is installed in bark pocket 2, the interior location of bark pocket 2 is inserted in the upper marginal position at books, be combined into the bascule of nested shape, function has been the effect of fixing top edge originally.In shape, structure and combination thereof, the Anti-rolling book cover folder of the present utility model technical characterictic different with immediate prior art is: the bonding position, the lower right corner that is connected bark pocket 2, the long side face position of right angle 3, the bonding position, the lower left corner that is connected bark pocket 2, long side face position of left side angle 4, be combined into the fixed structure of rib vertebra shape, function has been to be inserted in the effect that the book angle prevents book angle volume wrinkle.

Below by using method, further set forth the dynamic structure relation of this practical Anti-rolling book cover folder: in use, in the time of needs folder books, principle according to machinery, at first books are put into bark pocket 2, then clamp bar 1 is inserted on the bark pocket 2, will have seen book angle page or leaf insert in the angle 5 more then, thereby finish the folder books and prevent the task that the angle volume wrinkles.

In use, when needs are seen books,, at first the page of having seen is inserted in the angle 5, directly can translate into this page or leaf when read a book next time then, thereby finish the task of playing bookmark when reading a book according to the principle of machinery.So just realized the only fixing technical scheme of the technical problem of top but following two easy crimpings in angle of Book cover clip before the solution of Anti-rolling book cover of the present utility model folder.

Realize that preferred plan of the present utility model is is material to mould firmly, utilize the basic equipment of stationery factory, take to produce by batch in a large number, with supply science, student, etc. the demand of all circles, so just can realize the practical value and the economic worth of Anti-rolling book cover folder of the present utility model better.
