Abstract

The utility model relates to a novel blackboard eraser, which belongs to the technical field of the group of cleaning devices of blackboards or stone boards of the subclass of articles for writing or drawing; auxiliary articles for writing or drawing of the class of office supplies; writing or drawing devices under the subsection of printing in the section of performing operations and transporting according to the International Patent Classification (IPC). The utility model has the number of B43L21/00 and is composed of a left electromagnet, a blackboard eraser, a permanent magnet, a slide block, a blackboard, a guide rod, a blackboard frame, a wire, a switch box, a right electromagnet, a left switch and a right switch. The utility model is characterized in that the left electromagnet is arranged on the left position of the blackboard frame. The utility model is a novel blackboard eraser with practical value.

Description

A kind of novel blackboard eraser
The utility model relates to a kind of novel blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, and the big class of office appliance is write or drawing article, writes or figure assistant product group the cleaning device technical group field of blackboard or slabstone.Classification number is B43L21/00.
At present, the technology about the cleaning device of blackboard or slabstone existing and that once had was all done very fruitful effort to the demand of novel blackboard eraser, also once designed many outstanding technical schemes.As the Decree of Patent Office of China in 1996 by the flourish newspaper of Shen Ou Xiang, Granted publication number is CN2235904Y, China Patent No. (ZL) is: No. 95208815.9 utility model title is the utility model patent of " dust absorption blackboard eraser ", the technical scheme that is adopted.Cleaning device technical elements at blackboard or slabstone is a routine of great value invention, and it has solved the problem that blackboard eraser can dust suction effectively.But still have some deficits, it also is difficult to solve the problem unhygienic with hand, effort gas that erases the board.
The purpose of this utility model is to provide a kind of novel blackboard eraser.With solution erase the board with hand unhygienic, the effort gas problem.
The purpose of this utility model is achieved in that a kind of novel blackboard eraser of this utility model.Mainly constitute by left electromagnet, blackboard eraser, permanent magnet, slide block, blackboard, guide rod, blackboard frame, lead, switch enclosure, right electromagnet, left-handed opening, right switch.Its left electromagnet, permanent magnet, lead, switch enclosure, right electromagnet, left-handed opening, right switch are by selecting for use on the market.Its slide block is a square shape, uses plastic material, through the thermoforming processing and manufacturing.Its guide rod is an elongate in shape, uses aluminum alloy materials, through the mould molding processing and manufacturing.Left side electromagnet adopts adhesive method to be installed in the left part position of blackboard frame, constitutes the square shape connecting structure, and function has been a sucking action.Guide rod adopts adhesive method to be installed in the upper position of blackboard frame, constitutes the square shape connecting structure, and function is to play supporting role.Slide block adopts adhesive method to be installed in the upper position of permanent magnet, constitutes the elongate in shape connecting structure, and function has been the sliding motion effect.Blackboard eraser adopts adhesive method to be installed in the lower position of permanent magnet, constitutes the elongate in shape connecting structure, and function has been the effect of erasing the board.Right electromagnet adopts adhesive method to be installed in the right part position of blackboard frame, constitutes the square shape connecting structure, and function has been a sucking action.So just realized the purpose of this utility model.
The utility model has been compared two advantages and improvement with the original blackboard or the cleaning device technology of slabstone;
The first, because the utility model has designed electromagnet in technical scheme, so can realize the motion of blackboard;
The second, because the utility model has designed slide block in technical scheme, so can realize the blackboard eraser translation; Thereby just can more effectively solve the problem unhygienic with hand, effort gas that erases the board.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of a kind of novel blackboard eraser of the utility model;
The numbering of parts explanation in the schematic diagram: 1 left electromagnet 2 blackboard erasers 3 permanent magnets 4 slide blocks 5 blackboards 6 guide rods 7 blackboard frames 8 leads 9 switch enclosures 10 right electromagnet 11 left-handed openings 12 right switches
In the optimum implementation of a kind of novel blackboard eraser of the utility model, 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, a kind of novel blackboard eraser of the utility model.Mainly constitute by left electromagnet 1, blackboard eraser 2, permanent magnet 3, slide block 4, blackboard 5, guide rod 6, blackboard frame 7, lead 8, switch enclosure 9, right electromagnet 10, left-handed opening 11, right switch 12.Left side electromagnet 1 adopts adhesive method to be installed in the left part position of blackboard frame 7, constitutes the square shape connecting structure, and function has been a sucking action.Guide rod 6 adopts adhesive method to be installed in the upper position of blackboard frame 7, constitutes the square shape connecting structure, and function is to play supporting role.Slide block 4 adopts adhesive method to be installed in the upper position of permanent magnet 3, constitutes the elongate in shape connecting structure, and function has been the sliding motion effect.Blackboard eraser 2 adopts adhesive method to be installed in the lower position of permanent magnet 3, constitutes the elongate in shape connecting structure, and function has been the effect of erasing the board.Right electromagnet 10 adopts adhesive method to be installed in the right part position of blackboard frame 7, constitutes the square shape connecting structure, and function has been a sucking action.
Its dynamic structure: in force:
According to the magnetic attachment principle, its left electromagnet 1 by suction in permanent magnet 3, thereby finish the task that blackboard eraser moves to left.According to the magnetic attachment principle, its right electromagnet 10 is used for permanent magnet 3 by suction, thereby finishes the task that blackboard eraser moves to right.So just realized the purpose of this utility model.Thereby just can solve the problem unhygienic with hand, effort gas that erases the board.
Below by using method, the utility model is done more detailed description:
A kind of novel blackboard eraser of this utility model is work like this:
In use, when using the time of the present utility model, if realize that blackboard eraser 2 moves to left, then make left-handed opening 11, right switch 12 make left electromagnet 1 in running order, right electromagnet 10 outages rely on the magnetic force of generation like this, force blackboard 2 to be moved to the left.
In use, when use is of the present utility model, if realize that blackboard eraser 2 moves to right, then use left-handed opening 11 and right switch 12 to make left electromagnet 1 be in off-position, right electromagnet 10 is in running order, relies on the magnetic force that produces like this, forces blackboard eraser 2 to move right.
Realize that preferred plan of the present utility model is is material with aluminium alloy, plastics, utilize the basic equipment of blackboard eraser processing factory, take assembling 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.
