Abstract

A novel chalk belongs to the technical field of the non-propelling pencil, stencil pen, color pen and chalk group in the writing or drawing appliance subclass of office article class in the print writing or drawing appliance branch of the operation transport department according to international patent classification (IPC) table. The utility model aims to achieve hand injury-free and skidproof purposes. The novel chalk consists of a chalk, a paper strip and a skidproof film. The utility model is characterized in that the paper strip is completely bundled on the outer surface of the chalk, and the skidproof film is completely coated on the outer surface of the paper strip.

Description

New-type chalk

(1) technical field:

The utility model relates to new-type chalk, divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or the drawing appliance group non-propelling pencil; Stylus; Crayon; The chalk technical group field.

(2) background technology:

At present, existing and once had about non-propelling pencil; Stylus; Crayon; The technology of chalk group was all done very fruitful effort to the needs of new-type chalk, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 2008 by Shen Qiuxia, Granted publication number is CN20121770Y, China Patent No. (ZL) is: the utility model title of 200820301160.X is the utility model patent of " chalk ", and the technical scheme that is adopted is at non-propelling pencil; Stylus; Crayon; Chalk group technical elements be an example very in the invention that is worth, this has solved the technical problem of chalk effectively.But still have some deficits, it also is difficult to separate never hinders hand; Anti-skidding technical problem.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of new-type chalk.Never hinder hand to separate; Anti-skidding technical problem.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: the new-type chalk of utility model, main chalk, paper slip, non-skid film constitute.Its major part chalk, non-skid film are selected for use by market.Its paper slip is the strip shape, for being material, passes through the machined manufacturing with paper.

In shape, structure and combination thereof, the total essential features of new-type chalk of the present utility model and immediate prior art is: the integral body of chalk is made the integrative-structure cylindrical shape by powder knot technology, and function has been the effect of chalk.In shape, structure and combination thereof, the new-type chalk of the present utility model technical characterictic different with immediate prior art is: the integral position of paper slip is bundled in the outer surface of chalk, is combined into the combining structure of chalk shape, and function has been the effect of not hindering hand.The integral position of non-skid film is coated in the outer surface of paper slip, is combined into the chalk shape, and function has been anti-skidding effect.What so just reached new-type chalk of the present utility model does not hinder hand; Anti-skidding purpose.

The beneficial effect of the new-type chalk of utility model is that the utility model is never hindered hand for separating; The anti-skidding technical scheme that technical problem adopted and existing and once had about non-propelling pencil; Stylus; Crayon; The technology of chalk group has been compared two place's advantage and improvement:

The first, owing to designed the outer surface that the integral position of paper slip is bundled in chalk in the technical scheme of new-type chalk of the present utility model, so the easier technical problem of never hindering hand of separating.

The second, owing to designed the outer surface that the integral position of non-skid film is coated in paper slip in the technical scheme of new-type chalk of the present utility model, so the anti-skidding technical problem of easier solution.

(4) description of drawings:

Accompanying drawing provides the structural representation of the new-type chalk of the utility model:

Fig. 1: the overall structure schematic diagram that is the new-type chalk of the utility model.The label declaration at each position in the schematic diagram;

1 chalk, 2 paper slips, 3 non-skid films

(5) specific embodiment:

Below in conjunction with accompanying drawing, new-type chalk of the present utility model is never hindered hand for realizing separating; The optimal way of the technical scheme that anti-skidding technical problem is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, new-type chalk of the present utility model mainly is made of chalk 1, paper slip 2, non-skid film 3.Its major part chalk 1, non-skid film 3 are selected for use by market.Its paper slip 2 is strip shapes, for being material, passes through the machined manufacturing with paper.

In shape, structure and combination thereof, the total essential features of new-type chalk of the present utility model and immediate prior art is: the integral body of chalk 1 is made the integrative-structure cylindrical shape by powder knot technology, and function has been the effect of chalk.In shape, structure and combination thereof, the new-type chalk of the present utility model technical characterictic different with immediate prior art is: the integral position of paper slip 2 is bundled in the outer surface of chalk 1, be combined into the combining structure of chalk shape, function has been the effect of not hindering hand.The integral position of non-skid film 3 is coated in the outer surface of paper slip 2, is combined into the chalk shape, and function has been anti-skidding effect.

Below by using method, further set forth the dynamic structure relation of the new-type chalk of the utility model: in use, when needs are not hindered hand, according to theory of mechanics, at first the integral position of paper slip 2 is bundled in the outer surface of chalk 1, thereby finishes the task of not hindering hand.

In use, when needs were anti-skidding, according to theory of mechanics, at first the integral position of non-skid film 3 was coated in the outer surface of paper slip 2, thereby finished the task of not hindering hand.That has so just realized the new-type chalk of the utility model does not hinder hand; Anti-skidding technical problem.

Realize that the utility model preferred plan is with plastic material, utilize the basic equipment of common process factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of the new-type chalk of the utility model better with the demand of supply educational circles.

Claims
