Abstract

The utility model provides an non-fouling eraser which comprises a housing, a sticky roller, a shaft and an eraser; an eraser cavity, a crumb removal cavity and a roller cavity are arranged in the housing respectively; the eraser is clamped in the eraser cavity; the sticky roller is fixed in the roller cavity through the shaft, and can freely roll around the shaft; the crumb removal cavity is arranged between the roller cavity and the eraser cavity; the upper part of the crumb removal cavity is opened, the bottom of the crumb removal cavity is in contact with the surface of the sticky roller, and the distance between the lower end of the side wall of the crumb removal cavity and the surface of the sticky roller is greater than the diameter dimension of eraser crumbs; and the eraser crumbs enter the crumb removal cavity via a gap between the lower end of the side wall and the surface of the sticky roller. The non-fouling eraser can automatically remove the eraser crumbs reserved after the incorrect handwriting is removed by the eraser, so that the desktop is tidy and clean, and the trouble of wiping off eraser crumbs by hand is handled.

Description

A kind of no dirty erasing rubber

Technical field

The utility model relates to a kind of stationery, the especially a kind of nothing dirt erasing rubber that can eliminate the rubber bits.

Background technology

The student is after using erasing rubber to wipe the wrong person's handwriting of writing with pencil, tend to stay a lot of rubber bits, desktop is made very dirty, when flipping, can make dirty by handle again, and stroke unclean with hand, some rubber bits can embed in the slits such as desktop or books, make the desktop things seem very dirty year in year out, and all will stroke rubber bits after using erasing rubber at every turn, comparatively trouble.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of no dirty erasing rubber, and this does not have dirty erasing rubber can eliminate erasing rubber automatically and wipe the rubber bits that stay behind the wrong writing, makes desktop neatly clean, and has solved the trouble of flipping the rubber bits with hand.

The technical scheme that its technical problem that solves the utility model adopts is: this does not have dirty erasing rubber and comprises housing, the viscosity cylinder, axle, rubber, be respectively equipped with the rubber chamber in the housing, clear bits chamber, the cylinder chamber, rubber is installed in the rubber chamber, the viscosity cylinder is fixed in the cylinder chamber by axle, the viscosity cylinder can freely roll around axle, clear bits chamber is located at the centre in cylinder chamber and rubber chamber, the top in clear bits chamber is open-minded, the bottom contacts with the viscosity cylinder surface, the distance of side wall lower ends and viscosity cylinder surface is greater than the diameter dimension of rubber bits, during use, the rubber bits space by side wall lower ends and viscosity cylinder surface enters considers the chamber clearly to be worth doing.

As preferably, described rubber chamber is a cuboid cavity.

As preferably, described rubber is a cuboid rubber.

As preferably, described clear bits chamber is a cuboid cavity.

As preferably, described cylinder chamber is a semicircular cavities.

As preferably, described viscosity cylinder is a cylindrical bala gutta body.

The beneficial effects of the utility model are: this does not have dirty erasing rubber in the process of wiping mistake writing, rubber left rubber bits in the place ahead are glued by the viscosity cylinder surface at rear to be got, and send into and consider to be worth doing clearly in the chamber, being considered to be worth doing the bottom, chamber more clearly scrapes, stay in clear bits chamber, at last, only need and to turn around by no dirty erasing rubber, the rubber bits can be poured out, this does not have dirty erasing rubber can eliminate the rubber bits that stay behind the rubber wiping erroneous words mark automatically, make desktop neatly clean, and solved the trouble of whisking off the rubber bits with hand.

Description of drawings

Fig. 1 is a semi-section structural representation of the present utility model.

Coding among the figure is respectively: 1 is housing; 2 is clear bits chambeies; 3 is the cylinder chamber; 4 is the viscosity cylinder; 5 is axle; 6 is rubber; 7 is the rubber chamber.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

As shown in Figure 1, this does not have dirty erasing rubber and comprises housing 1, viscosity cylinder 4, axle 5, rubber 6, be respectively equipped with rubber chamber 7 in the described housing 1, consider chamber 2, cylinder chamber 3 to be worth doing clearly, described rubber 6 is installed in the rubber chamber 7, described viscosity cylinder 4 is fixed in the cylinder chamber 3 by axle 5, and described clear bits chamber 2 is located at the centre in cylinder chamber 3 and rubber chamber 7, and the top in described clear bits chamber 2 is open-minded, the bottom contacts with viscosity cylinder 4 surfaces, and the distance on side wall lower ends and viscosity cylinder 4 surfaces is greater than the diameter dimension of rubber bits.

Above-mentioned nothing dirt erasing rubber, rubber chamber 7 is a cuboid cavity.

Above-mentioned nothing dirt erasing rubber, rubber 6 is a cuboid rubber.

Above-mentioned nothing dirt erasing rubber, considering chamber 2 clearly to be worth doing is a cuboid cavity.

Above-mentioned nothing dirt erasing rubber, cylinder chamber 3 is a semicircular cavities.

Above-mentioned nothing dirt erasing rubber, viscosity cylinder 4 is a cylindrical bala gutta body.

Above-mentioned nothing dirt erasing rubber is in the process of wiping mistake writing, rubber 6 left rubber bits in the place ahead are glued by viscosity cylinder 4 surfaces at rear to be got, enter into by the space between clear bits chamber 2 side wall lower ends and the viscosity cylinder 4 and to consider chamber 2 clearly to be worth doing, the bottom of being considered to be worth doing chamber 2 more clearly scrapes, stay in clear bits chamber 2, at last, only need and to turn around by no dirty erasing rubber, the rubber bits can be poured out, this does not have dirty erasing rubber can eliminate the rubber bits that stay behind the rubber wiping erroneous words mark automatically, make desktop neatly clean, and solved the trouble of whisking off the rubber bits with hand.
