Abstract

The utility model relates to an environmental protection eraser and belongs to dust and chalk ash suction device subgroup technical field, blackboard or flagstone cleaning device group, calligraphy or drawing appliance and calligraphy or drawing auxiliary appliance subclass, calligraphy or drawing appliance and office supplies class, printing subsection, performing operations, transporting section according to International Patent Classification (IPC) table. A class number is B43L21/02. The utility model consists of a lattice ruler, a grove, a soft leafspring, chalk, eraser wood, a sponge and a leather packing. The utility model is characterized in that the sponge is arranged on the lower part of the eraser wood and is an environmental protection eraser which is provided with utilization value.

Description

Environmental protection chalk is wiped

The utility model relates to environmental protection chalk and wipes.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 drawing article, the assistant product group of writing or draw, and big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.Classification number is B43L21/02.

At present, the demand that the technology about the sucking chalk powder device is arranged existing and that once had is wiped environmental protection chalk was all done very fruitful effort, also once designed many outstanding technical schemes.Declare as growing into forest of the Decree of Patent Office of China in 1996 by beam, Granted publication number is CN2233325Y, China Patent No. (ZL) is: No. 95200484.4 utility model title is the utility model patent of " wet type is inhaled grey blackboard eraser ", the technical scheme that is adopted.Having aspect the sucking chalk powder device technique is a routine of great value invention, and it has solved the problem that the blackboard eraser wet type is inhaled ash effectively.But still have some deficits, it also is difficult to solve dust mobile problem that causes dust pollution in air when erasing the board.

The purpose of this utility model is to provide environmental protection chalk to wipe.Dust flows in air and causes the problem of dust pollution when erasing the board with solution.

The purpose of this utility model is achieved in that this utility model environmental protection chalk wiping.Mainly constitute by lattice chi, groove, soft spring sheet, chalk, blackboard eraser wood, sponge, leather packing.Its sponge, leather packing are by selecting for use on the market.Its lattice chi is a centimetre chi shape, uses wooden material, through accurate carpenter's processing and manufacturing.Its groove is a cube shaped, with carpenter chiseler processing and manufacturing.Its soft spring sheet is a flake shape, uses the steel material, through the mechanical compaction processing and manufacturing.Its blackboard eraser wood is cube shaped, uses wooden material, through carpenter's planing processing and manufacturing.The soft spring sheet adopts and hammers into the inner wall position that method is installed in groove, constitutes the flake shape elastic construction, and function has been to clamp standby chalk effect.Sponge adopts half adhesive method to be installed in the lower position of blackboard eraser wood, constitutes cube shaped blackboard eraser structure, and function has been the effect of erasing the board of band water.Leather packing adopts adhesive method to be installed in the lateral location of blackboard eraser wood, constitutes cube shaped protection structure, the comfortable effect of feel when function has been use.So just realized the purpose of this utility model.

The advantage of utility model: the utility model has been compared three advantages and improvement with the original sucking chalk powder device technique that has;

The first, because the utility model designed water-absorbing sponge in technical scheme, so can dustlessly erase the board and do soon;

The second, because the utility model has designed the lattice chi in technical scheme, so can be used to setting-out;

The 3rd, because the utility model has designed groove in technical scheme, so can store chalk; Thereby just can more effectively solve dust mobile problem that causes dust pollution in air when erasing the board.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the plan structure schematic diagram that the utility model environmental protection chalk is wiped;

Fig. 2 is the left TV structure schematic diagram that the utility model environmental protection chalk is wiped;

The numbering of parts explanation in the schematic diagram: 1 lattice chi, 2 grooves, 3 soft spring sheets, 4 chalks, 5 blackboard erasers wood, 6 sponges, 7 leather packings

In the optimum implementation that the utility model environmental protection chalk is wiped, 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 environmental protection chalk is wiped.Mainly constitute by lattice chi 1, groove 2, soft spring sheet 3, chalk 4, blackboard eraser wood 5, sponge 6, leather packing 7.Soft spring sheet 3 adopts and hammers into the inner wall position that method is installed in groove 2, constitutes the flake shape elastic construction, and function has been to clamp standby chalk effect.Sponge 6 adopts half adhesive method to be installed in the lower position of blackboard eraser wood 5, constitutes cube shaped blackboard eraser structure, and function has been the effect of erasing the board of band water.Leather packing 7 adopts adhesive method to be installed in the lateral location of blackboard eraser wood 5, constitutes cube shaped protection structure, the comfortable effect of feel when function has been use.Its lattice chi 1 adopts rose method to be engraved in the top right-hand side position on the long limit, the back side of blackboard eraser wood 5, constitutes an oblong-shaped lattice chi, and function is the effect of setting-out section.Groove 2 adopts method for turning processing in the centre position, the back side of blackboard eraser wood 5, constitutes the cavity of a groove shapes, and function has been the effect of placing standby chalk.

Its dynamic structure: in force:

According to the washing principle, its sponge 6 acts on blackboard eraser wood 5 by leather packing 7, thereby finishes dustless task of wiping.Its lattice chi 1 acts on blackboard eraser wood 5, thereby finishes the task of setting-out.Its chalk 4 acts on soft spring sheet 3 by groove 2, thereby finishes the standby task of chalk.So just realized the purpose of this utility model.Thereby just can solve dust mobile problem that causes dust pollution in air when erasing the board.

Below by using method, the utility model is done more detailed description:

It is work like this that this utility model environmental protection chalk is wiped:

In use, when erasing the board, grasp leather packing 7 and move sponge, according to the washing principle, its sponge 6 acts on blackboard eraser wood 5 by leather packing 7, thereby finishes dustless task of wiping.

In use, when the setting-out chalk uses up, can use according to different needs, its lattice chi 1 acts on blackboard eraser wood 5, thereby finishes the task of setting-out.Its chalk 4 acts on soft spring sheet 3 by groove 2, thereby finishes the standby task of chalk.

Realize that preferred plan of the present utility model is is material with timber, utilize the basic equipment of manual factory, take small lot to produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
