Description

General-purpose self-tightening is adjustable spliting and joining type file binder and article clamp device

Affiliated technical field

The invention belongs to clamping of file, paper part, and the packaging of other industry various article and turnover.

Background technology

Although a lot of offices have adopted with no paper office, still have a large amount of paper part files, as contract note, bidding documents, legal documents, read and make comments part etc.And these paper part files are often still very important.Therefore the classification of file, stepping, keeping, protect, fetch and read and packaging carrying, just need all kinds of folders, this folder, grooved folder, folder, file pouch etc.And move for the Put on file that exceedes above-mentioned packing material and hold the file of scope, can only tie up or case with rope.This tends to damage file and very inconvenient.

For thinner file, now widely used damage-free file clamps apparatus 3 kinds, i.e. dovetail clip, iron clamp and grooved folder.While opening due to dovetail clip and iron clamp, must use pressing piece,, after clamping, pressing piece is exactly unnecessary.The inconvenience that this has just caused file to place.After particularly file thickness has exceeded the maximum opening width of clip, clip is just helpless.Although grooved presss from both sides without pressing piece, higher to the requirement of file thickness, requires great effort very much when clamping---leicht fallen D/A is not clamping.Above-mentioned 3 kinds of clips can only clamp in the end of file.

Also have a lot of article need to pack turnover box, therefore also need to sort out concentrated protection and place, pack carrying.As books, textiles, glasswork, food (cake, birthday cake) etc., what have a not to be stowed under heavy cargo not can be fastening, also has very rapid wear, the breakables of not to be stowed under heavy cargo.

At present packaging carrying, the protection of above-mentioned article being placed, is a large amount of employing carton, rope (strap), adhesive tape bindings.Because the solidness of carton is lower, therefore also lower to the degree of protection of article, and generally can not have enough to meet the need again.

Summary of the invention

The present invention " general-purpose self-tightening is adjustable spliting and joining type file binder and article clamp device " is designated hereinafter simply as " general-purpose grip box ".

The object of this invention is to provide " self-tightening, adjustable, separate, combination " this common technical scheme, so that produce the multiple any position that goes for clamping file, without casting die, can easy disassembly, multiduty, self-tightening mode and can regulate the binder of the paper part file of length, width, thickness, in order to clamping with no damage, keeping and move.

The present invention also applies this technical scheme simultaneously, to multiple industry, various article---also the zero damage including paper part file, protect placement, packaging, carrying simply and easily.

The technical solution used in the present invention is: on the side of the inner clamp piece of being made up respectively of the elastomeric thin plate of having of two separation and outer intermediate plate, be processed with respectively the convex and concave teeth or groove gear and/or the perforation that lock, when application, combine and become folder, this folder---file binder, or become article clamp device, the multiple accessories being mated can be installed simultaneously.

Binder---clamping, packing appliance; Clamp device---the apparatus clamping after packaging.

General-purpose grip box, according to structure, purposes, can be divided into four large classes, i.e. single side class, double side class, three side classes and four side class.For double side class and three side classes wherein, can also be divided into two classes of " regular length " and " random length ".Each class general-purpose grip box, can have Multiple Type.

It should be noted that: the mechanics principle of four large class general-purpose grip boxs applied " gripping power " is different, therefore structure is also different, and purposes is also different.

For the general-purpose grip box of single side, the side knuckle of inner clamp piece and outer intermediate plate is all less than 90 °, so when after inner clamp piece and the locking of outer clip sheet, because the corner of file or paper part is 90 °, so single side and intermediate plate after compressing are also in 90 °.Now the elastic force of side self can produce the horizontal positive pressure parallel with file face to the end of file or paper part, and the antagonistic force of file will be pushed the side of intermediate plate open, but owing to existing friction force between intermediate plate and file.Therefore folder is tighter, and friction force is just larger; Friction force is larger, folder just tighter.For this thinner file---as two pages of paper, because the antagonistic force of file is too little, thus have to increase intermediate plate later and bending increase the pressure of the side to clamping.

For the universal clamp of double side or three sides, what its gripping power relied on is the antagonistic force that gives stress and elastic force and file.Therefore intermediate plate bending in advance, the knuckle of outer intermediate plate should be less than 90 ° simultaneously, and the knuckle of inner clamp piece is greater than 90 ° to ensure keeping certain locking pressure between inside and outside intermediate plate.

The size of gripping power, depends on the modulus of elasticity of material and size and the gauge of sheet of side knuckle and gives the size of stress.

By the elastomeric thin plate of having of two separation respectively bending forms inner clamp piece and the outer intermediate plate of side, by its side respectively processing and manufacturing be can sell friction tight convex and concave teeth and/or perforation is connected; Wherein, for each inner clamp piece and the outer intermediate plate of file binder, have two sides at least, for inner clamp piece and the outer intermediate plate of article clamp device, have four sides at least, the multiple annex coordinating with it can be installed simultaneously on inner clamp piece and outer intermediate plate.

General-purpose self-tightening adjustable spliting and joining type file binder for optional position is to be bent into U-shaped in the appropriate location, two ends of thin plate; The knuckle of outer intermediate plate is not more than 90 °, and the knuckle of inner clamp piece is not less than 90 °, and thin plate can be prefabricated interior curved simultaneously, and the length of outer intermediate plate should be longer than the twice gauge of sheet of inner clamp piece; The width of inner clamp piece and outer intermediate plate can equate with length and the width of file or paper part.

The thin plate that is used for the adjustable spliting and joining type folder of the one-sided general-purpose self-tightening binder of the optional position, end of file is only rolled over a curved rear one-tenth dihedral, and the knuckle of one-sided inner clamp piece and one-sided outer intermediate plate is not more than 90 °.

For the adjustable spliting and joining type file of the self-tightening binder of file end, be that thin plate is carried out to three bendings, except side corresponding to both sides, have a side at least in another side, the knuckle of outer intermediate plate is not more than 90 °, and the knuckle of inner clamp piece is not less than 90 °.

For the further annex of locking inner clamp piece and outer intermediate plate, can be remain silent lock ring, opening lock ring and in grip.

For the adjustable spliting and joining type file of the general-purpose self-tightening binder of random length, formed by two one-sided outer intermediate plates and two one-sided inner clamp pieces, and there are the convex and concave teeth and/or the perforation that lock in two sides of intermediate plate.

The adjustable spliting and joining type file of general-purpose self-tightening binder for thick and heavy file, paper part packaging and carrying is the lifting ear that is connected in the appropriate location of intermediate plate, and handle passes through, and side hook or hook sheet and lifting ear are moving to be connected.

The adjustable spliting and joining type file of the general-purpose self-tightening binder that tooth and hole lock, the length in its hole should be greater than C times of pitch of holes---the columns that C is hole, the position in every row hole is longitudinally differing C/mono-, and all empty size and pitch of holes all equate---starter hole and stop hole can except.

Outer intermediate plate and inner clamp piece for the minimum adjustable spliting and joining type file of the general-purpose self-tightening binder that is two pages of paper have intermediate plate later, and there is bending the end that one of them intermediate plate is turned one's head.

Annex of the present invention can also be the disconnector of the safe edge of rectangular shaped and the inside and outside intermediate plate that is acute angle by three all rectangular corner protectors of face and one end.

For the article clamp device of the adjustable spliting and joining type of general-purpose self-tightening, the convex and concave teeth on the side becoming in its four sides bending or the locking direction of groove tooth and/or perforation are that every two adjacent sides are for reverse.

Be used for the article clamp device of the adjustable spliting and joining type of general-purpose self-tightening of the layer boxlike of packing carrying, have at least layer box and two the outer intermediate plates that an inner clamp piece curves to form.

The invention has the beneficial effects as follows: owing to can the side connection location of general-purpose grip box being carried out to free adjustment in certain scope, by manufacturing the side of different range, just can obtain the general-purpose grip box of random length, width, thickness so.

Due to the present invention adopt be " clamping ", therefore without " punching ".Simultaneously due to can installation accessories---safe edge, corner protector, therefore the present invention be not only and preserves with no damage file, and protected file effectively.

Clamp, make the use of the file such as amendment, duplicating of file become very convenient.The particularly general-purpose box of " four side ", preservation to file, places, fetches, mobilely all reached best effect.

Because the present invention can, with annex---lock ring, opening lock ring and locking clamp firmly fix inside and outside intermediate plate, therefore have " bookbinding " even the effect of file---drop to the ground, also can not throw away.

Because the present invention does not have the pressing piece of the additional standalone feature of dovetail clip, iron clamp, so general-purpose grip box is simple in structure.This performance not only makes after file clamping without unnecessary parts, thereby makes folder attractive in appearance, clean and tidy, well-behaved, and easy to manufacture, produces efficient, cost.

Because the present invention can clamp in the optional position of file, therefore clamp rear overall performance good, can place optional position, for example longitudinally clamp with two folders, file just can fitly stand up.This is that dovetail clip, iron clamp are not accomplished.

Because the present invention can install handle, therefore can carry easily.Can also multiple files be bound into book form by binder ring.

The technical scheme of the general-purpose grip box of " four sides ", increases function and the purposes of general-purpose grip box greatly.In theory, because general-purpose grip box has had the function of " chamber ", therefore can deposit any article.Particularly " the reverse teeth of adjacent two sides " structure of general-purpose grip box, makes the height of chamber not only adjustable, but also can fix, and can also form " multilayer box " simultaneously.This structure, not only make general-purpose grip box can clamp not to be stowed under heavy cargo not as the article of files classes, textile, but also article that can " clamping " easy damaged, as soft beancurd, glasswork.And the general-purpose grip box of boxlike " layer " goes for every layer of article and can allow depositing, transporting of article that people see.For example transport, put multilayer birthday cake.

General-purpose grip box and common chamber maximum is not both universal clamp box can multilayer, content space, protection and the turnover products to be packaged of adjustable and can fixed adjustment good general-purpose grip box.If the general-purpose grip box of four sides adopts high-intensity elastomeric material, make as metal, engineering plastic pocket, so not only reliability is improved, and increases the service life, but also can be for the turnover of commodity package, can Reusability, as freight container.Certainly, general-purpose grip box can be placed in freight container well-behavedly.

The separation of inside and outside intermediate plate of the present invention, can use as the disconnector of Figure 35.For example, in loading the general-purpose grip box of four sides, can, oppositely placing disconnector in flank, then press down outer intermediate plate.While opening, first disconnector is inserted in the middle of inside and outside intermediate plate, carry on then.Certainly the various implements with acute angle, as pocket knife, are all the connections that can open inside and outside intermediate plate.
