Abstract

The utility model discloses an eraser clamp. The eraser clamp comprises an eraser and a clamp cover arranged outside the eraser, wherein a U-shaped clamp sheet is further arranged in the clamp cover, and the clamp sheet is an integrated piece and is formed by bending two flexible edges on the clamp sheet; the eraser is clamped in a clamp opening of the clamp sheet and is hooped and locked through the clamp cover arranged outside the clamp sheet in a sleeved mode. According to the eraser clamp, the eraser is wrapped in the clamp opening of the clamp sheet by bending the two flexible edges on the clamp sheet, then, the clamp sheet is sleeved with the clamp cover, the eraser is hooped through the clamp cover, and therefore the eraser is clamped by the eraser clamp conveniently and effectively.

Description

A kind of Rubber eraser clamp

Technical field

The utility model relates to a kind of Rubber eraser clamp.

Background technology

Rubber is the indispensable a kind of stationery of student, teacher and designers, conventionally new rubber is bought its outer rubber case that is surrounded by papery, rubber case is packed and is had transparent plastic more outward, during use, transparent plastic removes, make rubber have at least a part to expose in external environment, some people will tear off together with the whole external packing of rubber case.Because rubber is comparatively soft and very easily dirty, this is not also finished with regard to usually having become dirty and having occurred fracture or pit rubber, not only affect the attractive in appearance of rubber, and it is very unhygienic that rubber is used.In addition, people, when using rubber, along with the shortening, diminish of rubber, need to take out rubber from rubber case, are also likely directly embedded in rubber case, bring great inconvenience to the use of rubber.

The existing patent No. is that the Chinese utility model of CN201020573082.6 discloses a kind of Liftable eraser, its structure comprises rubber, described rubber is arranged in rubber case, described rubber case for opening above all the other time seal, described rubber case bottom is provided with a push rod, and push rod is fixed together through rubber case bottom surface and rubber.This utility model is because rubber is comparatively soft, and the frictional force between rubber case is larger, and this gives makes troubles rubber from releasing in rubber case; In addition, if adopt larger gap between rubber and rubber case, also can bring adverse influence for the use of rubber.

Separately having the patent No. is that the Chinese utility model of CN201220484986.0 discloses a kind of rubber, comprises rubber body, it is characterized in that, in described rubber body one end, be set with rubber case, rubber case is connected with hairbrush; On described rubber case, have a shape, size and the corresponding cavity of hairbrush, while not using described in hairbrush be just in time positioned at this cavity.What this utility model adopted equally is that rubber is directly placed in rubber case, the excesssive gap between rubber case and rubber, and rubber easily slides arbitrarily in rubber case, affects the result of use of rubber; Between rubber case and rubber, gap is too small,, due to superpower toughness and the great coefficient of friction of rubber, makes rubber be difficult for extracting out in rubber case.

Utility model content

The technical problems to be solved in the utility model is the present situation for prior art, provides a kind of clamping convenient, effective, and can keep rubber to clean, be easy to the Rubber eraser clamp that rubber is used.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of Rubber eraser clamp, comprise rubber, and be located at the chuck outside rubber, it is characterized in that: in described chuck inside, be also provided with a U-shaped intermediate plate, this intermediate plate is integrated part, two pliability spring foldings on it, consists of; Described rubber is clamped in the jaws of intermediate plate, and is locked by the chuck banding being enclosed within outside intermediate plate.

As improvement, at the clamp mouth part near described intermediate plate, be provided with protuberance.Protuberance can adopt several parallel raised lines to form, fashionable at chuck cover like this, can further utilize the protuberance on intermediate plate that rubber is clamped.In addition, protuberance is arranged on to the clamp mouth part of intermediate plate, makes when rubber shortens, intermediate plate also can clamp rubber effectively.

Improve again, on the intermediate plate side contacting with described chuck, be provided with slide guide bar, make intermediate plate more smooth from extracting or insert in chuck.

Improve, the opening part of described chuck is provided with recessed otch again, is provided with accordingly the projection offseting with described otch on described intermediate plate.Otch and projection can design the shapes such as semicircle, circular arc, and both convenient finger was released intermediate plate, also can play spacing effect mutually simultaneously.

Improve again, on the contiguous pliability of described intermediate plate limit, be provided with the projection of spacing use.By projection is set, effectively limit the bending degree of intermediate plate, to contain that pliability limit, due to the excessive appearance fracture of amplitude of bending, guarantees service life.

Compared with prior art, owing to the utility model has the advantage of: rubber is arranged on and has guaranteed clean, health and the integrality of rubber in omnidistance use procedure in chuck; Intermediate plate is inserted in intermediate plate in chuck after utilizing two the pliability springs folding on it rubber to be wrapped in the jaws of intermediate plate, utilizes chuck by rubber banding, thereby has realized the effective clamping of Rubber eraser clamp to rubber; In addition, because rubber does not directly contact with chuck, prevented that bending from appearring in rubber when inserting or extracting chuck.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figures 1 to 6, a kind of Rubber eraser clamp in this enforcement, comprise rubber 3, and be located at the chuck 1 outside rubber 3, and in this chuck 1 inside, being also provided with a U-shaped intermediate plate 2, this intermediate plate 2 is plastics integral piece, by two pliability limits, 26 bendings on it, form, at the clamp mouth part near this intermediate plate 2, be provided with protuberance, this rubber 3 is clamped in the jaws of intermediate plate 2, and is locked by chuck 1 banding being enclosed within outside intermediate plate 2.

Wherein, this protuberance can consist of several parallel raised lines 22, fashionable at chuck 1 cover like this, can further utilize the raised line 22 on intermediate plate 2 that rubber 3 is clamped, and improves clamping effect.In addition, this raised line 22 is arranged on the clamp mouth part of intermediate plate 2, makes when rubber 3 shortens, and intermediate plate 2 also can clamp rubber 3 effectively.

In addition, on intermediate plate 22 sides that contact with chuck 1, be provided with slide guide bar 25, this slide guide bar 25 separates chuck 1 inner surface and intermediate plate 2 outer surfaces, has reduced the contact area between intermediate plate 2 and chuck 1, makes intermediate plate 2 more smooth from extracting or insert in chuck 1,

In addition, the opening part of chuck 1 is provided with recessed otch 11, is provided with accordingly the projection 24 offseting with this otch 11 on intermediate plate 2.Otch 11 can design the shapes such as semicircle, circular arc with projection 24, has both facilitated finger to release intermediate plate 2, also can play spacing effect mutually simultaneously, prevents that intermediate plate from too inserting and colliding with chuck diapire.Meanwhile, for further increasing the frictional force between finger and projection 24, these projection 24 surfaces are for rough surface and be provided with pit 27 in this projection 24.

Finally, on intermediate plate 2 contiguous pliability limits 26, be provided with the projection 23 of spacing use, by projection 23 is set, can effectively limit the bending degree of intermediate plate 2, to contain that pliability limit 26 is due to the excessive appearance fracture of amplitude of bending.

In use, first rubber is inserted in the jaws of intermediate plate, then be inserted in chuck can.When rubber is with short or while being finished, as long as the rubber of adjusting rubber extension elongation or more renewing is simple and easy to use.
