Abstract

The utility model relates to a novel practical book end relates to office supplies or domestic stationery class articles for use, belongs to the novel centre gripping utensil of document that uses on the desktop, can firmly hold book clip and erect to can keep not loose for a long time, the structure of the innovation access books that also facilitate the use simultaneously, thus eliminated among the daily life desktop books and always can not erect and place, and incompact confusion often.

Description

A kind of novel practical book end

Technical field

A kind of novel practical book end of the present invention is related to office appliance or family expenses stationery class articles for use, and belonging to one kind makes on the table Document novel clamping utensil.

Background technology

The basic profile of book end of various versions existing in the market is all easy L shaped plate, cost be it is more cheap, But also there are many born defects, such as：A will typically lean on corner to place competence exertion effect;B books place effect when thicker Can be relatively good, but mostly relatively thin books then easily scatter, and perform practically no function；C is typically difficult to realize and allows books to stand to put, mostly When be all to allow books to lean to put, day long afterwards easily to books cause damage.

The content of the invention

A kind of novel practical book end of the present invention, mainly by base plate, fixed side and mobile side board constitute a kind of clipping type Structure, makes books to keep for a long time erectting placement not loosely between fixed side and mobile side board, can not lean on wall or corner.

By being fixedly connected between fixed side and base plate, knot that can be undone by a pull connection and chute connection between mobile side board and base plate, Base plate building block system splicing construction can free development length, make between fixed side and mobile side board embrace a clip space can freely adjust It is whole, to adapt to different user needs.

With special-shaped involute gear on mobile side board, it is also possible to stepped tooth, circle-arc tooth etc., and match somebody with somebody in base plate correspondence position Have the tooth bar of identical modulus, acted on by torsion spring and position limiting structure, make can easily to be carried out between wheel and rack lock with Unclamp.

Coordinated using U-lag gap between the chute plate part of mobile side board and base plate, made between mobile side board and base plate Relative rectilinear can be made while will not unclamp.

Fixed side is fixedly connected with base plate, be by way of the concavo-convex buckle structure of swallow-tail form is in combination with elastic card, Allow fixed side to firmly hold very much vertical connection status with base plate, also can pull down by hand, be also the foldable of the book end Structure provides feasible condition, and packaging and cost of transportation are greatly reduced after foldable integral.

Base plate building block system splicing construction is mainly docked using the concavo-convex buckle structure head and the tail of swallow-tail form, may also be employed being similar to Card carve structure for example trapezoidal, the structure such as circle, ease of assembly and dismounting.

Specific embodiment

It is shown that the reality of the new style book stand uses scene, several thickness to differ in Fig. 1, the different book of appearance and size This, allows books wherein to keep erectting placement by 3 liang of fixed side 1 and mobile side board in static condition in the face of folder State, can lean on the wall also can be without by wall.

When needing to increase books, only need to be at the end angle with the light plate mobile side board 3 of hand, the end angle is by limited block The angle of chamfer determines that in other words, while mobile side board 3 can not be pulled again, fixed special shape gear 8 also departs from tooth bar 7 simultaneously, So far coulisse 4 can just follow the hand power thrusts of operator to move linearly, and realize clamping or vacateing the two of placement space Plant action.

As shown in figure 3, mobile side board 3 is connected with coulisse 4 by 6 one-tenth movable pins of axle, limited by the angle of coulisse 4 Bit architecture, makes mobile side board to rotate in certain angle（This legend is fixed tentatively as 60 degree of angles）, it is therefore an objective to convenient use person operates, When hand leaves mobile side board 3, because the effect of torsion spring 5 makes mobile side board 3 recover the plumbness with base plate 2 automatically, while solid Determine special shape gear 8 and keep plumbness and stuck state with base plate 2 in interlocking pattern, that is, mobile side board 3 with tooth bar 7, Firmly oppose cooperation with fixed side, will not retreat, it is ensured that books between the two also keep plumbness.

As shown in figure 4, base plate 2 is a kind of building block system splicing construction, two stitching portion is the concavo-convex buckle structure of swallow-tail form, first Tail can be assembled, will not release in the horizontal direction, and base plate 2 is also a kind of optional accessory, and client is according to oneself placement space demand Its requirement can be chosen, the book end for spelling different length thus can be freely taken.

As shown in figure 5, fixed side 1 passes through to keep tight with base plate 2 plus elastic buckles 11 while swallow-tail form occlusion structure Button connection, its intensity be enough to books clamping to keep vertical.

This kind of whole assembling of book end need not use screw, and all directly assembly by hand, takes up room little, such as Fig. 6 during gathering Shown, easily dress is easily received, and all parts are that in addition to metal material, other are engineering plastics making, once squeeze except axle 6 and torsion spring 5 Go out shaping, holistic cost is cheap, be relatively adapted to popular popularization.

Claims

1. a kind of practical book end, is characterized in that by base plate, consist of draw-in groove splicing between fixed side and mobile side board three A kind of clipping type structure, be wherein fixedly connected holding vertical relation between base plate and fixed side, mobile side board and base plate it Between be chute knot that can be undone by a pull connection also keep vertical relation, make books for a long time to keep setting to put between fixed side and mobile side board Put not loose.

2. a kind of practical book end according to claim 1, is characterized in that base plate can be freely extended with building block system splicing construction Length, makes armful clip space between fixed side and mobile side board freely to adjust, to adapt to different user needs.

3. a kind of practical book end according to claim 1, is characterized in that knot that can be undone by a pull connection is to pass through between mobile side board and base plate With abnormity gradually shape gear on mobile side board, or the tooth-shape structure such as stepped tooth, circle-arc tooth, and it is furnished with phase in base plate correspondence position Realize with the tooth bar of modulus, along with torsion spring and position limiting structure effect, make easily be locked between wheel and rack Button and release.
