Description
(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, 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 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 23rd October in 2002 by Wang Haining, Granted publication number is CN2517591Y, China Patent No. (ZL) is: 01228299.5 utility model patent title is the utility model patent of " Dustless eraser ", the technical scheme that is adopted.The technical elements of the cleaning device group of blackboard or slabstone is a routine of great value invention, and it has solved blackboard of every wiping effectively has two to wipe roller in work, and this suitable other blackboard eraser has been wiped the technical problem of twice effect.But still have some deficits, it is slow that it also is difficult to solve the speed that erases the board; The sordid technical problem of wiping.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel blackboard eraser.Slow with the speed that solution erases the board; The sordid technical problem of wiping.
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: at the bottom of going up scroll wheel, upper groove, large pulley, blackboard, stay cord, truckle, large pulley axle, low groove, down at the bottom of scroll wheel, blackboard eraser, truckle axle, the upper groove, blackboard eraser hair, low groove, go up rolling shaft, rolling shaft constitutes down.Its major part stay cord, last scroll wheel, following scroll wheel, large pulley, truckle are selected for use by market.Its upper groove, low groove are the character cut in bas-relief shapes, are material with the steel, through the casting processing and manufacturing.Its blackboard eraser is an oblong-shaped, with timber, cotton material, through digging the mill 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: an end position of blackboard eraser hair has the glue chain to be connected the reverse side position of blackboard eraser, be combined into blackboard and examine the fixed structure of shape, function has been the effect of wiping letter written with chalk.In shape, structure and combination thereof, the novel blackboard eraser of the present utility model technical characterictic different with immediate prior art is: a side position of upper groove is connected the upper position of blackboard with nail, one side position of low groove is connected the lower position of blackboard with nail, be combined into OBL overall structure, function has been the effect of the track of scroll wheel.The center of last scroll wheel is installed in the upper end position of blackboard eraser with roller bearing, and the center of following scroll wheel is installed in the lower end position of blackboard eraser with roller bearing, is combined into the bascule of rectangular shape, and function has been the effect that Sliding blackboard is wiped.Be connected the top of blackboard eraser and pulley at a linear position with an end position of rope, be connected the bottom of blackboard eraser and pulley position in line with an end position of another root rope, be combined into bascule, function has been the effect of pulling blackboard eraser.The speed that erases the board with regard to the solution that has realized novel blackboard eraser of the present utility model is slow like this; The purpose of the sordid technical problem of wiping.
The beneficial effect of the novel blackboard eraser of utility model is: the utility model is slow for solving the speed that erases the board; The technical scheme that sordid technical problem adopted of wiping has been compared three advantages and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had:
First, because a side position that has designed upper groove in the technical scheme of novel blackboard eraser of the present utility model is connected the upper position of blackboard with nail, one side position of low groove is connected the lower position of blackboard with nail, be combined into OBL overall structure, so the technical problem of track that can easier solution scroll wheel.
Second, because the center of having designed last scroll wheel in the technical scheme of novel blackboard eraser of the present utility model is installed in the upper end position of blackboard eraser with roller bearing, the center of following scroll wheel is installed in the lower end position of blackboard eraser with roller bearing, be combined into the bascule of rectangular shape, thus can be easier the solution Sliding blackboard technical problem of wiping.
The 3rd, be connected the top of blackboard eraser and pulley at a linear position owing to designed a end position with rope in the technical scheme of novel blackboard eraser of the present utility model, be connected the bottom of blackboard eraser and pulley position in line with an end position of another root rope, be combined into bascule, thus can be easier the technical problem of solution pulling blackboard eraser.
