Description

Hollow eraser

The utility model relates to a kind of cultural goods, relates in particular to a kind of hollow shape erasing rubber.

Erasing rubber is used existing so far quite long history, with regard to existing erasing rubber structure, can be divided into several haply, first kind is the cylindric erasing rubber of establishing with the iron plate corral on the pencil top, this kind structure all concentrates on the joint of erasing rubber and iron plate in use owing to all strength, thereby in use ruptures through regular meeting; Second kind: be block structure, this kind structure is most popular on the market at present a kind of, manufacturer is in order to improve price simultaneously, also develop the erasing rubber of various difformities or color, though their wiping effect can both meet the demands, but in use be easy to loss and cause waste, this type of block erasing rubber is also very not convenient when taking simultaneously, because it is combined in the top of pencil unlike aforesaid erasing rubber, to from pencil box or drawer, take out separately and could use in use, seek worried during usually for use; The third: be the structure of lip pencil, the general pen of this kind erasing rubber length is long, therefore carries inconvenience, has only the student can be convenient for carrying when using pencil box usually.If do not use pencil box, carry very trouble, therefore this design can not be satisfied the convenient requirement of using.

In addition, existing erasing rubber only has the simple function that wipes, and also is its weak point.

The main purpose of this creation is: a kind of hollow shape erasing rubber is provided, and it is set in the penholder outside, takes conveniently, can make the user when gripping penholder, feels soft comfortable pain when avoiding writing when long or callous.Also, can utilize it to be polygonal or non-circular profile simultaneously, can not roll arbitrarily when making a tool be placed on the desktop, and the ground of dropping easily.

Below further specify design feature of the present utility model and purpose by a specific embodiment and in conjunction with its accompanying drawing.

Fig. 1 is a preferable stereogram of hollow shape erasing rubber of the present utility model;

Fig. 2 is that the hollow shape erasing rubber of Fig. 1 is set on the user mode figure on the hexagonal section pencil;

Fig. 3 is that the hollow shape erasing rubber of another embodiment of the present utility model is set on the profile on the circular cross-section pencil;

Fig. 4 is that the hollow shape erasing rubber of the embodiment of this Fig. 3 is set on the user mode figure on the circular cross-section pencil.

Now see also Fig. 1, as shown in the figure, erasing rubber 10 of the present utility model can be made a structure as tubulose, be through hole 11 in the central, the outside is polygonal or other non-circular shape, like this can with this erasing rubber 10 as sleeve as shown in Figure 2 on penholder 20 outer peripheral faces, with the convenience that provides the user to take erasing rubber 10, it is more handy to allow when using.

Erasing rubber 10 of the present utility model can be made suitable length, for being sheathed on penholder 20 outsides when using, form a sheath in penholder 20 outsides as shown in Figure 2, can allow the user so simultaneously when gripping penholder 20, have soft and comfortable gripping sense, this can be avoided pointing callous or pain concerning the people that some are write for a long time.

Because it is cylindrical that many penholders 20 are designed to, when making a tool be seated on desktop or the books, can tumble to ground because of inclination, be easy to cause and break or lose.Shown in Fig. 3,4, because sheathed erasing rubber 10 of the present utility model, can utilize it to be polygonal or other non-circular shape, and can not roll arbitrarily when making a tool on putting desktop, even or the ground of dropping easily is erasing rubber of the present utility model 10 deformation bowlder after use and outside making, also only be set in an end of penholder 20 because of it, and make penholder 20 when rolling, be the track of a circular arc, only do circular-arc swing on the table, and can not tumble table point-blank down.

Above-mentioned is the basic structure of hollow shape erasing rubber of the present utility model, also can make its profile variation make various shape, such as the appearance of cartoon doll, animal appearance or can hold the special appearance of a posture in order to rectification, these change also all in scope of the present utility model.

Claims (2)

1, a kind of hollow shape erasing rubber is characterized in that: erasing rubber is made structure as tubulose, be provided with the through hole that can sheathedly be assembled on the penholder in the central.

2, hollow shape erasing rubber according to claim 1 is characterized in that: the erasing rubber outside is polygonal or other non-circular shape.
