Description

Novel blackboard eraser

(1) technical field:

The utility model relates to novel blackboard eraser, 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 drawing article; The assistant product group of writing or draw, eraser, rubber or erasing apparatus, and used big group, the technical field of fiber eraser group.

(2) background technology:

At present, existing and once had about eraser, rubber or erasing apparatus, and used big group, the technology of fiber eraser group was all done very fruitful effort to the demand of novel blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China on the 26th October in 2002 by Wang Haining, Granted publication number is CN 2517591Y, China Patent No. (Z L) is: No. 01228299.5 utility model patent title is the utility model patent of " Dustless eraser ", the technical scheme that is adopted.Eraser, rubber or erasing apparatus, and used big group, the technical elements of fiber eraser group is a routine of great value invention, and it has solved blackboard of each wiping effectively has two to wipe rollers in work, and this is equivalent to the technical problem that other blackboard eraser has been wiped the effect of twice blackboard.But still have some deficits, it also is difficult to solve ordinary blackboard eraser and takes manpower, the technical problem of contaminated environment.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel blackboard eraser.Take manpower, the technical problem of contaminated environment to solve ordinary blackboard eraser.

The novel blackboard eraser that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: blackboard eraser, dust box, the right side advance button, a left side advance button, blackboard, micromotor, magnet, every magnetic holder, conveyer belt, iron core, hair wipe, the folder frame constitutes.Button is advanced on its major part right side, a left side is advanced button, micromotor, magnet, wiped and selected for use by market every magnetic holder, conveyer belt, iron core, hair.Its blackboard eraser is the strip shape, is material with plastics or lightweight timber, through the machining manufacturing.Its dust box is the long trough shape, is material with plastics, alloy or timber, through the machining manufacturing.Its blackboard is a rectangular shape, is material with the vulcanie, through the chemical treatment processing and manufacturing.Its folder frame is the strip shape, is material with rubber, through the chemical treatment processing and manufacturing.

In shape, structure and combination thereof, the total essential features of novel blackboard eraser of the present utility model and immediate prior art is: the end positions of blackboard eraser is connected to the respective ends position of folder frame, the disposition of feet chuck of folder frame is installed in the last top and the following bottom position of blackboard, be combined into the strip hair and wipe the bascule of shape, function has been the effect that freely erases the board.The rear wall fixed-site of dust box is connected the lower end position of blackboard, is combined into the integrative-structure of elongated slot shape, and function has been the effect that connects chalk dust.In shape, structure and combination thereof, the novel blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the nested inner chamber position that is installed in every magnetic holder of the integral position of magnet, every the be connected upper surface position of conveyer belt of the basal surface position of magnetic holder, be combined into the integrative-structure of vertical " ten " shape, function has been the effect that magnetic is moved back and forth.One fragment position cover of conveyer belt is connected the assigned address of micromotor, the integral position of motor is fixedly mounted on the inner chamber position of blackboard, motor links to each other with external switch, is combined into the integrated structure of electronic device shape, and function has been the effect of control magnet movement direction.The nested inner chamber position that is connected blackboard eraser of the integral position of iron core, the root position that hair is wiped is connected to the bottom surface position of blackboard eraser, the folder frame is fixed on the end positions of blackboard eraser, is combined into the integrative-structure that the strip hair is wiped shape, and function has been the effect of automatic blackboard cleaning plate.So just realized the solution ordinary blackboard eraser expense manpower of novel blackboard eraser of the present utility model, the purpose of the technical problem of contaminated environment.

The beneficial effect of the novel blackboard eraser of utility model is: the utility model is for solving ordinary blackboard eraser expense manpower, the technical scheme that technical problem adopted of contaminated environment and existing and once had about eraser, rubber or erasing apparatus, and used big group, the technology of fiber eraser group has been compared three advantages and improvement:

First, owing to designed the nested inner chamber position that is installed in every magnetic holder of integral position of magnet in the technical scheme of novel blackboard eraser of the present utility model, every the be connected upper surface position of conveyer belt of the basal surface position of magnetic holder, be combined into the integrative-structure of vertical " ten " shape, so the technical problem that can easier solution magnetic is moved back and forth.

Second, because a fragment position cover that has designed conveyer belt in the technical scheme of novel blackboard eraser of the present utility model is connected the assigned address of micromotor, the integral position of motor is fixedly mounted on the inner chamber position of blackboard, motor links to each other with external switch, be combined into the integrated structure of electronic device shape, so technical problem that can the easier solution controlling magnet direction of motion.

The 3rd, owing to designed the nested inner chamber position that is connected blackboard eraser of integral position of iron core in the technical scheme of novel blackboard eraser of the present utility model, the root position that hair is wiped is connected to the bottom surface position of blackboard eraser, the folder frame is fixed on the end positions of blackboard eraser, be combined into the strip hair and wipe the integrative-structure of shape, so technical problem that can easier solution automatic blackboard cleaning plate.
