Abstract
The utility model discloses a multifunctional eraser which comprises two strip-type extensible bands and two strip-type erasers. Each extensible band is an elastic structure. The extensible bands and the erasers are connected in alternate mode and form a tubular structure with a through hole in the middle. The area of the through hole is ten to seventy-five square millimeters. The external diameter of the sector at two ends of each eraser is ten to twenty millimeters. The external diameter in the middle part is seven to twelve millimeters. The thickness of the extensible bands which are at the connecting portions of the extensible bands and erasers is the same as the erasers. The thickness of the middle part of the cross section of the extensible band is zero point one to two millimeters. When the extensible bands extend, the area of the through hole is maximally nine times the area of the through hole when the extensible bands do not extend. The multifunctional eraser has simple structure, is capable of wiping the handwriting and increasing the area of the penholder, and improves the holding comfortableness.
Description
Technical field
The utility model relates to a kind of stationery, particularly a kind of multipurpose erasing rubber that is enclosed within on the penholder.
Background technology
The pen of existing band rubber usually rubber amount all seldom, and common rubber can not be contained on the pen, carry respectively, and pencil has only penholder, gripping local thinner also skidded inconvenience easily.Chinese patent application number: 200920282241.4, open day: on September 29th, 2010, the utility model title: a kind of rubber, a scheme that can be contained in the rubber on the penholder is provided, an end of this utility model rubber body has patchhole, the other end is connected with bristle, the afterbody of bristle is inserted in the rubber body, owing on the rubber body tool patchhole is arranged, random notes carry on the penholder so this utility model can be contained in, but it is too thin to solve penholder gripping place, can problem of slip.
Summary of the invention
The utility model carries for the solution rubber can connect together with pen, and penholder is too thin, problem of slip, and a kind of multipurpose erasing rubber easy to use simple in structure is provided.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: a kind of multipurpose erasing rubber, described multipurpose erasing rubber comprises two bar shaped telescopic bands and two bar shaped rubbers, telescopic band is an elastic construction, the alternate centre that connects and composes of telescopic band and rubber is the tubular structure of through hole, via area is 20 to 75 square millimeters, the fan-shaped external diameter in rubber two ends is 10 to 20 millimeters, the external diameter of mid portion is 7 to 12 millimeters, telescopic band is identical with the telescopic band thickness and the rubber of rubber junction, the thickness of telescopic band cross section mid portion is 0.5 to 2 millimeter, when telescopic band was stretched out, via area was 9 times when not stretching out to the maximum.
Because described multipurpose erasing rubber comprises two bar shaped telescopic bands and two bar shaped rubbers, telescopic band is an elastic construction, the alternate centre that connects and composes of bar shaped telescopic band and rubber is the tubular structure of through hole, via area is 20 to 75 square millimeters, when telescopic band is stretched out, it is big that the area of through hole becomes, via area is when stretching out 3 times structure to the maximum, the area of general pen is greater than 9 square millimeters, less than 700 square millimeters, after so the utility model telescopic band is stretched out, can be enclosed within on the penholder of the general pen of using always, such as pencil, the utlity model has telescopic band when not stretching out, 10 to 20 millimeters of the fan-shaped external diameters in rubber two ends, the structure that the external diameter of mid portion is 7 to 12 millimeters, so the utility model two is pluckings, middle thin, when writing the utility model is enclosed within the place of finger grip on the penholder, can increase the diameter of gripping place, the thin shape and structure in two pluckings centres is fit to the gripping of finger, the elastic construction of telescopic band and rubber can increase the gripping comfort level, simultaneously, the utility model two ends thick highlights the rubber at two ends, during the wiping vestige, it is the available rubber wiping that protrudes in penholder that pen is laid across, and telescopic band is identical with the thickness and the rubber of rubber junction telescopic band, and the thickness of telescopic band cross section mid portion is 0.5 to 2 millimeter structure, telescopic band and rubber are connected firmly, therefore, the utility model has solved the rubber random notes well and has carried, and with the time be enclosed within the place of holding a pen to solve penholder thin, problem of slip.
As preferably: there is groove in the described telescopic band outside, and groove can increase the comfort level of gripping.
As preferably: the two ends of described multipurpose erasing rubber, the external diameter of an end is bigger 5 to 10 millimeters than the external diameter of the other end, and this shape is more suitable for gripping.
As preferably: described rubber one end is for wiping the soft rubber material-structure of pencil vestige, the other end is for wiping the hard rubber material-structure of ball pen vestige, better as the rubber applicable performance like this, wherein, wipe the soft rubber material-structure of pencil vestige and the hard rubber material-structure of wiping ball pen vestige and be known configurations.
As preferably: described telescopic band is 0.5 to 1 times of rubber subtended angle to the subtended angle of through hole center line.
The beneficial effects of the utility model are, middle via area can enlarge and is enclosed within on the common penholder, can be used as the pen cap that grips usefulness when writing, rubber protrudes in outside the penholder, and is during the wiping vestige, that pen is horizontal in getting final product, the utility model is easily manufactured, and random notes carry, and achieves many things at one stroke.
