Abstract
The utility model relates to a blackboard eraser, which consists of a supporting board, a blackboard, a guide way, an axes handle, a return board, a rag and a putter. The utility model is characterized in that: a guide way screw is arranged at the lower rim of the blackboard. As added with a long return board as a paralleling guide way, the utility model can rapidly and effortless erase the blackboard; and as added with a guide way putter mechanism which complies with the ergonomic, the utility model is energy saving and efficiency enhancing, so the utility model is a new blackboard eraser with practical value.
Description
(1) technical field:
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; The big class of office appliance is write or drawing article, the assistant product group of writing or draw, the cleaning device technical group field of blackboard or slabstone.
(2) background technology:
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 declaring of the Decree of Patent Office of China in 1996 by Zhao Weiguang, Granted publication number is CN2233323Y, China Patent No. (ZL) is: No. 95213178.1 utility model title is the utility model patent of " band dust-collecting cup chalk dust ledge ", 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 of the grey troughed belt dust-collecting cup of pen effectively.But still have some deficits, it is not high with small blackboard wiping efficient before also being difficult to solve, and easily makes the problem of people's fatigue, hand pain.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel blackboard eraser.With not high before solving, and easily make people's fatigue, hand problem bitterly with small blackboard wiping efficient.
The purpose of this utility model is achieved in that a kind of novel blackboard eraser of this utility model.Mainly constitute by gripper shoe, blackboard, guide rail, axle handle, slide plate, wiper, push rod.Its blackboard, wiper are by selecting for use on the market.Its gripper shoe is an elongate in shape, uses steel plate materials, through forging processing and manufacturing.Its guide rail is the elongated slot shape, uses the steel material, through forging processing and manufacturing.Its axle is used the steel material being the spindle shape, through forging processing and manufacturing.Its slide plate is a long plate shape, uses the steel material, through forging processing and manufacturing.Its push rod is the circular shaft shape, uses the steel material, through forging processing and manufacturing.Gripper shoe adopts the screw method to be installed in the lateral location of blackboard, constitutes the rectangular shape syndeton, and function has been to support protective effect.Guide rail adopts the screw method to be installed in the last lower position of blackboard, constitutes the rectangular shape syndeton, and function has been the slide guide effect.Axle constitutes spindle shape overall structure adopting welding method to be installed in the end positions of slide plate, and function has been balance slip effect.Slide plate adopt contact method be installed in guide rail between the position, constitute long plate shape blackboard eraser structure, function has been to put wiper, drive slip effect.Wiper adopts method of attaching to be installed in the lower surface position of slide plate, constitutes the Brush Shapes overall structure, and function has been the effect of erasing the board.Push rod adopts the screw method to be installed in the centre position of slide plate, constitutes T word shape chi structure, and function has been to promote the skateboarding 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 the original blackboard or the cleaning device technology of slabstone;
The first, because the utility model has designed in technical scheme that long slide plate is made blackboard eraser and with the structure of guide rail, so erase the board fast and leicht fallen D/A;
The second, because the utility model has designed guide rail push rod effort-saving mechanism in technical scheme, so meet ergonomics, force-saving synergistic; Thereby not high before just more effectively having solved, and easily make people's fatigue, hand problem bitterly with small blackboard wiping efficient.
(4) description of drawings:
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall structure schematic diagram of a kind of novel blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 4 on 1 gripper shoe, 2 blackboards, 3 guide rails are 5 slide plates, 6 wipers, 7 push rods
(5) specific embodiment:
In the optimum implementation of a kind of novel blackboard eraser of the present 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: see also Fig. 1: as shown in the figure, a kind of novel blackboard eraser of the present utility model.Mainly by gripper shoe 1, blackboard 2, guide rail 3, axle 4, slide plate 5, wiper 6, push rod 7 constitute.Gripper shoe 1 adopts the screw method to be installed in the lateral location of blackboard 2, constitutes the rectangular shape syndeton, and function has been to support protective effect.Guide rail 3 adopts the screw method to be installed in the last lower position of blackboard 2, constitutes the rectangular shape syndeton, and function has been the slide guide effect.Axle adopts 4 welding method to be installed in the end positions of slide plate 5, constitutes spindle shape overall structure, and function has been balance slip effect.Slide plate 5 adopt contact methods be installed in guide rail 3 between the position, constitute long plate shape blackboard eraser structure, function has been to put wiper, drive slip effect.Wiper 6 adopts method of attaching to be installed in the lower surface position of slide plate 5, constitutes the Brush Shapes overall structure, and function has been the effect of erasing the board.Push rod 7 adopts the screw method to be installed in the centre position of slide plate 5, constitutes T word shape chi structure, and function has been to promote the skateboarding effect.
Its dynamic structure: in force:
According to mechanics principle, its wiper 6 acts on slide plate 5 by push rod 7, thereby finishes erasing the board fast of task.According to tribology principle, its blackboard 2 acts on wiper 6 by slide plate 5, thereby finishes the task of erasing person's handwriting.So just realized the purpose of this utility model.Thereby not high before just having solved, and easily make people's fatigue, hand problem bitterly with small blackboard wiping efficient.
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 needs erase the board, only need to promote push rod 7 and just can wipe whole blackboard very soon.According to mechanics principle, its wiper 6 acts on slide plate 5 by push rod 7, thereby finishes erasing the board fast of task.According to tribology principle, its blackboard 2 acts on wiper 6 by slide plate 5, thereby finishes the task of erasing person's handwriting.
Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of teaching aid factory, take to produce by batch in batches, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
