Abstract
The utility model relates to the technical field of educational apparatus, specifically to an eraser for avoiding excess chalk dust and dust emission when the writing on blackboard is erased, comprising an eraser case, an eraser, a boss, a dust-collecting box, a recess, a bolt, a rubber wheel, rubber, a hinge, a dust-preventing device and an end cover. The eraser case is in shape of rectangular solid and the dust-collecting box is in shape of rectangular solid; the rubber wheel is in shape of circular column; the rectangular solid eraser is arranged on the rectangular solid eraser case, forming a rectangular superstructure; the rectangular solid eraser case is arranged on the rectangular solid dust-collecting box, forming a rectangular integral structure; the circular column rubber wheel is sheathed on the circular column bolt, forming a circular column anti-dust structure; the recess shaped end cover is arranged on the rectangular solid eraser, forming a sealing shaped integral structure. The utility model solves the problems of storing dust, agglutinate eraser dust, and excess chalk powder caused by erasing the words.
Description
Technical field
The utility model relates to technical field of teaching instruments, relate to specifically a kind of when avoiding wiping writing on the blackboard chalk dust too much, the erasing rubber of airborne dust.
Background technology
At present, known eraser, rubber or erasing apparatus and the used clamping device combination technique thereof that is used for the blackboard writing on the blackboard all done very fruitful effort to the demand of novel rubber, also once designed many outstanding technical schemes.As being declared by Yue Xiaoyang of the Decree of Patent Office of China in 1996, Granted publication number is CN2216932Y, and China Patent No. (ZL) is: 94245434, No. 0 utility model title is the utility model patent of " motor-driven eraser ", the technical scheme that is adopted.At eraser, rubber or erasing apparatus; And used clamping device group technical elements is a routine of great value invention, and it has effectively solved the electronic problem of rubber.But still have some deficits, it also is difficult to solve the wiping word is the too much and antihygienic problem of a powder.
Technology contents
The purpose of this utility model is intended to overcome above-mentioned prior art defective, the too much problem of a powder when providing a kind of novel erasing rubber to wipe word to solve writing on the blackboard.
The purpose of this utility model is achieved in that erasing rubber is made of rubberized canvas hull, rubber, boss, scrap storage box, groove, bolt, rubber tire, rubber, folding, card bits device, end cap, its rubberized canvas hull is a rectangular shape, scrap storage box is a rectangular shape, rubber tire is a cylindrical shape, the rubber of rectangular shape is installed on the rubberized canvas hull of rectangular shape, forms the superstructure of a rectangular shape; The rubberized canvas hull of its rectangular shape is installed on the scrap storage box of rectangular shape.Form the overall structure of a rectangular shape; The rubber tire noose of its cylindrical shape is installed on the bolt of cylindrical shape, forms the anti-dandruff structure of a cylindrical shape.The end cap of its groove shapes is installed on the OBL rubber, forms a close-shaped overall structure.
Rubber by mating reaction in rubberized canvas hull, thereby make rubber satisfy wipe the requirement of word, its rubber by cementation in rubber tire, thereby make rubber finish the task of inhaling bits, so just realized the purpose of this utility model.
The utility model has been compared three advantages with known technology:
The first, because the utility model has designed scrap storage box in technical scheme, so solved the problem that can store scurf;
The second, because the utility model has designed rubber in technical scheme, so solved the problem of the rubber bits that can bond;
The 3rd because the utility model has designed lid end in technical scheme, so solved the problem that can cover rubber, thereby with regard to can more effectively solve the wiping word time the too much and antihygienic problem of a powder.

Fig. 2 is the scrap storage box and the rubber tire structural representation of a kind of novel rubber of the utility model;
Fig. 3 is the assembly structure schematic diagram of a kind of novel rubber of the utility model;
The numbering of parts explanation in the schematic diagram:
1 rubberized canvas hull, 2 rubbers, 3 boss, 4 scrap storage box, 5 grooves, 6 bolts, 7 rubber tires, 8 rubber, 9 foldings, 10 card bits devices, 11 lid ends.
The specific embodiment
Embodiment 1: as shown in the figure, and a kind of novel rubber of the utility model.Mainly by rubberized canvas hull 1, rubber 2, boss 3, scrap storage box 4, groove 5, bolt 6, rubber tire 7, rubber 8, folding 9, card bits device 10, lid end 11 constitutes.Its major part bolt 6, folding 9 is by selecting for use on the market.Its rubberized canvas hull 1 is a rectangular shape, makes material with plastics, through the hot forming processing and manufacturing.Its scrap storage box 4 is rectangular shapes, makes material with wood, through the planing operation manufacturing.Its rubber tire 7 is cylindrical shapes, makes material with rubber, through the hot forming processing and manufacturing.The rubber 2 of its rectangular shape adopts fitting method to be installed on the rubberized canvas hull 1 of rectangular shape, forms the superstructure of a rectangular shape.The rubberized canvas hull 1 of its rectangular shape adopts fitting method to be installed on the scrap storage box 4 of rectangular shape.Form the overall structure of a rectangular shape.The rubber tire 7 of its cylindrical shape adopts the noose method to be installed on the bolt 6 of cylindrical shape.Form the anti-dandruff structure of a cylindrical shape.The end cap 11 of its groove shapes adopts fitting method to be installed on the OBL rubber 2.Form a close-shaped overall structure.Its rubber 2 by mating reaction in rubberized canvas hull 1, thereby make rubber 2 satisfy the requirements of wiping words.Its rubber 8 in rubber tire 7, is inhaled the task of considering thereby rubber 8 is finished by cementation.So just realized the purpose of this utility model.Thereby powder comes too much and antihygienic problem in the time of just having solved the wiping word.
In embodiment 1, if the wiping word, under the rubber effect, the rubber bits drop on the rubber that is bonded in rubber tire, because the suction-operated of colloidality, the rubber bits are unlikely fall down, under the effect of card bits device, the rubber bits drop in the bits box again, thereby reach anti-dandruff purpose, after bits are full, can open folding, the rubber bits are poured out; After the wiping word finishes, also rubber can be got rid of end cap and cover.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with rubber, utilize the basic equipment of rubber processing factory, take assembled heat to be shaped as batch process, the demand with supply consumption circle so just can realize practical value of the present utility model and economic worth better.
