Abstract

The utility model relates to a multi-function chalk, which belongs to the technical field of the subgroup of the slate pencil in the large group of the iron pencil and the chalk of the non-movable pencil in the subcategory of writing or painting tool of the category of office supplies of the writing or drawing tools in the subpart of the printing of the part of operation transportation according to the classification of the International Patent Classification Table (IPC). The classification number is B43K29/12. The utility model comprises a griping handle, an outer jacket, a chalk, a slot and an oiled paper, which is characterized in that the oiled paper is arranged on the outer surface of the chalk and is a multi-function chalk with practical value.

Description

Multifunctional chalk
The utility model relates to multifunctional chalk.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or the drawing appliance group non-propelling pencil; Stylus; Big group of chalk, the little technical group field of slate pencil.Classification number is B43K29/12.
At present, the technology about slate pencil existing and that once had was all done very fruitful effort to the demand of multifunctional chalk, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Tang Peiying, Granted publication number is CN2207938Y, China Patent No. (ZL) is: No. 94247811.8 utility model title is the utility model patent of " screw type Propelling chalk ", the technical scheme that is adopted.At the slate pencil technical elements is a routine of great value invention, and it has solved the problem of chalk screw type activity effectively.But still have some deficits, it also be difficult to solve traditional chalk write, the too big problem of dust when erasing the board.
The purpose of this utility model is to provide multifunctional chalk.With solve traditional chalk write, the too big problem of dust when erasing the board.
The purpose of this utility model is achieved in that this utility model multifunctional chalk.Mainly constitute by handle, overcoat, chalk, breach, oilpaper.Its chalk is by selecting for use on the market.Its handle is a cylindrical shape, uses plastic material, through the injection moulding processing and manufacturing.Its overcoat is the barrel-shaped shape of open circles, uses sponge material, through the chemical industry processing and manufacturing.Its breach is an annular shape, through the machining manufacturing.Its oilpaper is the barrel-shaped shape of open circles, uses the oilpaper material, through the chemical industry processing and manufacturing.Handle adopts the clinkering method to be installed in the upper end position of chalk, constitutes the convex shape syndeton, and function has been a fixation.Overcoat adopts adhesive method to be installed in the outer surface position of oilpaper, constitutes hierarchical structure, and function has been the dust suction effect.Oilpaper adopts adhesive method to be installed in the outer surface position of chalk, constitutes hierarchical structure, and function has been a buffer action.Breach adopts cutting method to be installed in the outer surface position of overcoat, constitutes the toroidal disrupted configuration, and function has been the partition effect.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared two advantages and improvement with original slate pencil technology;
The first, because the utility model has designed the sponge overcoat in technical scheme, so can adsorb certain chalk dust;
The second, because the utility model has designed breach and handle in technical scheme, so can save chalk; Thereby just can more effectively solve traditional chalk write, the too big problem of dust when erasing the board.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 be the utility model multifunctional chalk partly cut open structural representation;
The numbering of parts explanation in the schematic diagram: 1 handle, 2 overcoats, 3 chalks, 4 breaches, 5 oilpaper
In the optimum implementation of the utility model multifunctional chalk, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, the utility model multifunctional chalk.Mainly by handle 1, overcoat 2, chalk 3, split 4, oilpaper 5 constitutes.Handle 1 adopts the clinkering method to be installed in the upper end position of chalk 3, constitutes the convex shape syndeton, and function has been a fixation.Overcoat 2 adopts adhesive method to be installed in the outer surface position of oilpaper 3, constitutes hierarchical structure, and function has been the dust suction effect.Oilpaper 5 adopts adhesive method to be installed in the outer surface position of chalk 3, constitutes hierarchical structure, and function has been a buffer action.Split 4 and adopt cutting method to be installed in the outer surface position of overcoat 2, constitute the toroidal disrupted configuration, function has been the partition effect.
Its dynamic structure: in force:
According to absorption principle, its overcoat 2 acts on chalk 3, thereby finishes the task of dust suction.Its handle 1 acts on chalk 3, thereby finishes the task of writing.Its overcoat 2 passes through breach 4, thereby finishes the task of continuing use.So just realized the purpose of this utility model.Thereby just can solve traditional chalk write, the too big problem of dust when erasing the board.
Below by using method, the utility model is done more detailed description:
This utility model multifunctional chalk is work like this:
In use, when not tearing overcoat, according to absorption principle, its overcoat 2 acts on chalk 3, thereby finishes the task of dust suction.Its handle 1 acts on chalk 3, thereby finishes the task of writing.
In use, when tearing overcoat, its handle 1 acts on chalk 3, thereby finishes the task of writing.Its overcoat 2 passes through breach 4, thereby finishes the task of continuing use.
Realize that preferred plan of the present utility model is is material with the chalk, utilize the basic equipment of chemical industry factory, take to produce by batch in a large number, the demand with supply stationery circle so just can realize practical value of the present utility model and economic worth better.
