The utility model relates to a kind of health blackboard eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation; Department of Transportation, 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 technical field of the cleaning device group of blackboard or slabstone.
(2) background technology:
At present, the technology about the cleaning device group of blackboard or slabstone existing and that once had was all done very fruitful effort to a kind of demand of health blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Chen Binghuang, Granted publication number is CN2228850Y, China Patent No. (ZL) is: No. 95244797.5 utility model patent title is the utility model patent of " novel blackboard eraser ", the technical scheme that is adopted, technical elements in the cleaning device group of blackboard or slabstone is a routine of great value invention, and it has solved the technical problem easily that erases the board effectively.But still have some deficits, it is unclean that it also is difficult to solve blackboard eraser, effort, antihygienic technical problem.
(3) summary of the invention
The purpose of this utility model is to provide a kind of health blackboard eraser.Unclean to solve blackboard eraser, effort, antihygienic technical problem.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: a kind of health blackboard eraser of the present utility model mainly is made of blackboard, upper slide bar, middle slide bar, drop shot, sideslip device, wiping shell, computer controller, perpendicular sliding device, battery, screw, pressure ash formula material.
In shape, structure and combination thereof, the total essential features of a kind of health blackboard eraser of the present utility model and immediate prior art is: the end positions of upper slide bar is installed in the upper end position of blackboard with screw, the end positions of drop shot is installed in the lower end position of blackboard with screw, be combined into the integrative-structure of straight-bar shape, function has been the effect of supporting.Press the upper end position of grey formula material to be connected to the lower position of wiping shell, the right end position of battery is assigned and is installed in the left part position of wiping shell, is combined into the integrative-structure of square shape, and function has been the effect that erases the board.In shape, structure and combination thereof, a kind of health blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the medium position of wiping shell is enclosed within the medium position of middle slide bar, the upper end position weldering of middle slide bar is connected the lower end position of sideslip device, be combined into the bascule of straight-bar shape, function has been the effect that blackboard eraser slides up and down.The pore location cover of sideslip device is installed in the medium position of upper slide bar, and the lower end position cover of middle slide bar is installed in the medium position of drop shot, is combined into the bascule of " worker " word shape, and function has been the effect of move left and right.The front position of perpendicular sliding device is assigned and is installed in the interior location of wiping shell, and the front position of computer controller is connected to the interior location of wiping shell, is combined into the integrative-structure of square shape, and function has been the effect of vertical motion.The solution blackboard eraser that has so just reached a kind of health blackboard eraser of the present utility model is unclean, effort, the purpose of antihygienic technical problem.
The beneficial effect of a kind of health blackboard eraser of utility model is: the utility model is unclean for solving blackboard eraser, effort, the technical scheme that antihygienic technical problem adopted has been compared three place's advantage and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had:
First, owing to designed the medium position that the medium position of wiping shell is enclosed within middle slide bar in the technical scheme of a kind of health blackboard eraser of the present utility model, the upper end position weldering of middle slide bar is connected the lower end position of sideslip device, be combined into the bascule of straight-bar shape, so the technical problem that easier solution blackboard eraser slides up and down.
Second, because the pore location cover that has designed the sideslip device in the technical scheme of a kind of health blackboard eraser of the present utility model is installed in the medium position of upper slide bar, the lower end position cover of middle slide bar is installed in the medium position of drop shot, be combined into the bascule of " worker " word shape, so the technical problem of easier solution move left and right.
The 3rd, assign the interior location that is installed in the wiping shell owing to designed the front position of perpendicular sliding device in the technical scheme of a kind of health blackboard eraser of the present utility model, the front position of computer controller is connected to the interior location of wiping shell, be combined into the integrative-structure of square shape, so the technical problem of easier solution vertical motion.
