Abstract
The present inventioninvention relates to a pencil lead, in particular to an erasable anti-slip pencil lead which can be erased after writing on paper. The present inventioninvention is characterized in that bossy teeth and tooth grooves are evenly spread on the outer surface of the pencil lead; when a pencil shell and the pencil lead match and form a pencil, a drawing pencil with such pencil lead is filled between the pencil shell and the pencil lead. Therefore, the use effect is very good: the lead does not slip even if the pencil is nearly used up and becomes very short. In this way, the present inventioninvention not only ensures the use effect of the color drawing pencil, but also prevents waste.
Description
Technical field
The present invention relates to a kind of pen core of pencil, especially a kind of back a kind of erasable anti-skid pencil core of wiping of available rubber of on paper, writing.
Background technology
At present, some pencils and paintbrush, the more especially pastel pencil that can wipe, because the problem of pen core material, the surface of pen core is how very lubricious, and it is very little with the adhesive force of a shell, how in use, the slide core phenomenon can take place, especially the after-stage of use, its slide core phenomenon is more outstanding, and this has not only caused inconvenience to the user, has influenced result of use, and owing to can not re-use down, also can cause waste,, also not have very good solution at present this.
Summary of the invention
Can wipe the problem that pencil paintbrush pen core exists at present in order to solve, the invention provides a kind of erasable anti-skid pencil core, pencil paintbrush with this pen core, its result of use is good especially, even using very short degree, pencil the slide core phenomenon can not take place yet, therefore, it had both guaranteed the result of use of this pastel pencil, had also stopped the generation of wasting phenomenon.
The present invention solves the concrete scheme that its technical problem adopts: between this pen core 5 and the shell 1, coated with adhesive 2 is promptly formed complete paintbrush after the applying; It is characterized in that: on the outer surface of pen core 5, be evenly distributed with the little double wedge 3 of protrusion and the little teeth groove 4 of depression; When shell 1 and pen core 5 couplings are coincide when being shaped, the little double wedge 3 that the adhesive 2 of filling between its shell 1 and the pen core 5 is covered with and the bonding plane of little teeth groove 4 superficial layers, increase that can several times, so the increase that also obtained several times of its bonding adhesive force.
Its beneficial effect is: the pencil paintbrush of this pen core, its result of use are good especially, even pencil the slide core phenomenon can not take place with very short to the end degree yet, therefore, it had both guaranteed the result of use of this pastel pencil, had also stopped the generation of wasting phenomenon.
Description of drawings
The invention will be further described below in conjunction with drawings and the embodiments;
Accompanying drawing is a structural principle schematic diagram of the present invention;
Among the figure, 1 shell, 2 adhesive, 3 little double wedges, 4 little teeth groove, 5 pen cores.
The specific embodiment
In the drawings, the surface of its pen core 5 can be rough little double wedge 3 and little teeth groove 4, also can be rough impression, lines, groove and coarse superficial layer; Such structure can thoroughly solve the slide core phenomenon.
In the drawings, the interior surface layers of its shell 5 also can be made and pen core 5 corresponding rough impressions, lines, groove and coarse surface.Such structure has just more increased the reliability that prevents slide core.
In the drawings, all spaces and top layer face between a shell and pen core 1 must fill up adhesive 2, can not fail to fill in phenomenon.
