Abstract
The utility model relates to an eraser which comprises a rectangular eraser block with semicircular notches, wherein the semicircular notches are located at four edges of the rectangular eraser block; a ratio of the diameter of the semicircular notches to the length of the edges is (0.3-0.4):1; the edge length of the rectangular eraser block is 3-5cm; and the thickness of the rectangular eraser block is 1-1.5cm. The eraser has the advantages that: the semicircular notches are respectively arranged at four edges of the eraser; during a use process, the four corners of the rectangular eraser block are utilized to erase a writing mark by a user; and even if the four corner angles are rubbed away, the semicircular notches also can present the corner angles, so that the user can conveniently and accurately erase and remove the target writing marks.
Description
Technical field
The utility model relates to a kind of rubber, belongs to the stationery technical field.
Background technology
Rubber always be with bulk appear at we in face of, not only moulding is dull, and often can because can not precisely wiping target writing and abandoned, cause unnecessary stationery to waste.Along with the time of using lengthens, the use face of rubber usually can rust, and it is not accurate that tend to occur wiping when using rubber that writing is carried out wiping this moment, the writing around the wiping target also wiped simultaneously, and then affected office efficiency.
Chinese patent CN1701970A provides a kind of rubber, it has side rubber section of foreign side (11) and is configured in inboard interior side's side rubber section (12) of above-mentioned side rubber section of foreign side (11), in above-mentioned side rubber section of foreign side (11), be provided with the resettlement section (14) of interior side's side rubber section (12), interior side's side rubber section (12) is configured in the above-mentioned resettlement section (14) movably, when stating in the use interior side's side rubber section (12), its outside to above-mentioned side rubber section of foreign side (11) is outstanding.This rubber can generate the bight again, can carry out at an easy rate the trickle part of literal etc. and wiping of area on a large scale.Design is complicated, manufacturing cost is high but be somebody's turn to do.
Summary of the invention
For above technical deficiency, the utility model provides a kind of rubber.
The technical solution of the utility model is as follows:
A kind of rubber comprises the rectangle rubber bumper with semi-circular indentation, and described semi-circular indentation is positioned on four limits of rectangle rubber bumper, and the length of side ratio on the diameter of described semi-circular indentation and its limit, place is 0.3～0.4:1.
Preferred according to the utility model, the profile of described rectangle rubber bumper is square or rectangular.
Preferred according to the utility model, described rectangle rubber bumper thickness is 1-1.5cm.
Preferred according to the utility model, the profile of described rectangle rubber bumper is square, and the square length of side is 3-5cm, and semi-circular indentation is symmetricly set in the centre on four limits.
Preferred according to the utility model, the profile of described rectangle rubber bumper is rectangle, and the long length of side is 5cm, minor face is long to be 3cm, semi-circular indentation is symmetricly set in the centre on four limits, and the diameter of the semi-circular indentation on the long limit is 2cm, and the diameter of the semi-circular indentation on the minor face is 1cm.
Excellent results of the present utility model is:
Rubber described in the utility model respectively is provided with a semi-circular indentation four length of sides, during use, people utilize four angles of rectangle rubber bumper that the writing of writing is carried out wiping, even if grind off four corner angle, described semi-circular indentation also can with present corner angle, conveniently make people that the target writing is carried out accurate wiping and remove, not only improved office efficiency, and the access times of increase rubber, reduce unnecessary waste.Because the rubber shape is regular, be convenient to packing, preserve, carry, prevent fractureing and breakage of rubber.
