Abstract

The utility model relates to an eraser with a protective sleeve. According to the utility model, the protective sleeve is sleeved outside the eraser, the protective sleeve is provided with an adjustment port, the position of the eraser in the protective sleeve is adjusted through the adjustment port, and the problem of insufficient hardness due to less cross-sectional area of the eraser is solved, and therefore, the eraser with the less cross-sectional area can scrub within a less range without influencing a surrounding environment.

Description

The erasing rubber of band sheath

Technical field

The utility model relates to a kind of erasing rubber with sheath, belongs to the optimization of erasing rubber technology.

Background technology

Erasing rubber is a kind of block structure of software, and shape is various, in actual use, has certain rigidity in order to make erasing rubber, all does thicklyer usually, and is also just bigger naturally with the contact area of paper.

During daily use, make mistakes when writing, or drawing the time makes mistakes, the scope of wiping if desired is less, and the position adjacent with fault domain just is easy to clip the position that should not wipe when word or picture are arranged.For the contact-making surface that makes erasing rubber and paper reduces, do the cross section of erasing rubber lessly, use inconvenience on the one hand, because erasing rubber will grasp use, too thin bad assurance; On the other hand, the hardness of erasing rubber itself is not high enough, easy flexural deformation firmly the time, and the real contact area during use is still bigger.Certainly, also can cut the shape that becomes to need to the area of section of erasing rubber and shape, but so not only waste but also bother.

Therefore, need to seek a kind of cross section and can do smallerly, can solve the hardness problem again, and erasing rubber easy to use.

Summary of the invention

The purpose of the utility model provides the less erasing rubber of the convenient band sheath that uses again of a kind of cross section.

The technical scheme of the utility model is: the erasing rubber of band sheath; Form by hollow sheath 1 and erasing rubber 2; Erasing rubber 2 is placed in the sheath 1 and uses, and erasing rubber 2 forms tight fit, sheath 1 both ends open with sheath 1 inwall; Sheath 1 is provided with regulates mouth 13, and the some of erasing rubber 2 is exposed outside sheath 1; Sheath 1 inwall is provided with the lug, nib 12 with the axis parallel of sheath 1; Erasing rubber 2 is provided with the groove 21 that forms the negative and positive coupling with lug, nib 12, inserts sheath 1 to erasing rubber 2, and lug, nib 12 gets in the groove 21 and plays positioning action; During use, stir to expose with hand and regulating mouthfuls 13 outer erasing rubbers 2, descend, it is done in sheath 1 vertically move the spacing of lug, nib 12 and groove 21.

Described adjusting mouthfuls 13 is communicated with an end opening of sheath 1.

Described sheath 1 is provided with two and regulates mouthfuls 13, and one of them is regulated mouthfuls 13 and is communicated with an end opening of sheath 1, and another regulates the other end open communication of mouth 13 and sheath 1.

Described sheath 1 is provided with more than one adjusting mouth, and described adjusting mouth is not communicated with sheath 1 openings at two ends.

Be provided with the lug, nib 12 more than at sheath 1 inwall; Be provided with the groove 21 of respective numbers at erasing rubber 2 outer walls.

Beneficial effect:

1, at rubber sassafras overcoat upper jacket; On sheath, be provided with and regulate mouth; Through regulating mouthful position of adjusting erasing rubber in sheath,, overcome because of an erasing rubber cross-sectional area problem not enough than hour hardness through the intensity and the protective effect of sheath; Make the less erasing rubber of cross-sectional area, can be in smaller scope wiping and do not influence surrounding enviroment;

2, sheath can repeat repeatedly to use, and can continue to use through the new erasing rubber of replacement after erasing rubber uses up.

The specific embodiment

As depicted in figs. 1 and 2, the erasing rubber of band sheath is made up of hollow sheath 1 and erasing rubber 2; Erasing rubber 2 is placed in the sheath 1 and uses, and erasing rubber 2 forms tight fit, sheath 1 both ends open with sheath 1 inwall; Sheath 1 is provided with regulates mouth 13, and the some of erasing rubber 2 is exposed outside sheath 1.

Like Fig. 3 and shown in Figure 4, sheath 1 inwall is provided with the lug, nib 12 with the axis parallel of sheath 1; Like Fig. 5 and shown in Figure 6, erasing rubber 2 is provided with the groove 21 that forms the negative and positive coupling with lug, nib 12, inserts sheath 1 to erasing rubber 2, and lug, nib 12 gets in the groove 21 and plays positioning action.During use, stir to expose with hand and regulating mouthfuls 13 outer erasing rubbers 2, descend, it is done in sheath 1 vertically move the spacing of lug, nib 12 and groove 21.

Regulate mouthfuls 13 the plurality of optional mode that is provided with, wherein a kind of preferred version is to regulate mouthfuls 13 to be communicated with an end opening of sheath 1, during use; Hold sheath, use the erasing rubber that exposes from the opening part of sheath 1 that wiping is carried out in the position of makeing mistakes, because the effect of sheath has strengthened the hardness of erasing rubber; And the interlock of lug, nib and groove makes erasing rubber be difficult for move left and right; Therefore, erasing rubber can be done smaller thinlyyer, and is even more ideal for the more common erasing rubber of the wiping effect of small size.

Regulate mouthfuls 13 the plurality of optional mode that is provided with, wherein a kind of preferred version is that described sheath 1 is provided with two and regulates mouthfuls 13, and one of them is regulated mouthfuls 13 and is communicated with an end opening of sheath 1, and another regulates the other end open communication of mouth 13 and sheath 1.When needs move erasing rubber, regulate mouth 13 through any and can carry out.

Regulate the plurality of optional mode that is provided with of mouth 13, wherein a kind of preferred version is that described sheath 1 is provided with more than one adjusting mouth, and described adjusting mouth is not communicated with sheath 1 openings at two ends.The adjusting mouth of this mode is located at the sheath middle part, can be that an adjusting mouth also can be two adjusting mouths that projection is overlapping.From regulating the erasing rubber that mouth exposes, should be able to stir with the hand or the instrument of using, its two ends to sheath are moved.

Erasing rubber can get into from arbitrary end of sheath, during use, only need expose an amount of erasing rubber.Because the booster action of sheath makes erasing rubber not yielding or mobile in use.

Sheath adopts plastics or sheet metal to make, and during use, holds sheath, and sheath can produce inside in a small amount distortion, make jacket inner wall tighter push down erasing rubber, make erasing rubber be difficult for sliding.

Sheath can be reused., erasing rubber can continue through the erasing rubber that more renews to use after using up.

The foregoing description only is to be used for the purposes of interpretation the utility model; And be not to be the restriction to the utility model, those skilled in the art are in the essential scope of the utility model; Make various variations or alternative, also should belong to the protection category of the utility model.
