The class number is B43L21/02. The utility model comprises a rotation shaft of restoring force, a rope, a handle, an abraded yarn and the blackboard, which is characterized in that the rotation shaft of restoring force is installed on the top of the blackboard. The dustless eraser has a significant practical value.
Description
The utility model relates to dust-free black board 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, big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.Classification number is B43L21/02.
At present, have now and big group of the cleaning device that once had, have the technology of sucking chalk powder device that the demand of dust-free black board eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As declaring of the Decree of Patent Office of China in 1996 by Lu Minggang, Granted publication number is CN2223201Y, China Patent No. (ZL) is: No. 95201619.2 utility model title is the utility model patent of " electronic wiping and dust-sucking eraser ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, it is a routine of great value invention that sucking chalk powder device technique aspect is arranged, and it has solved the problem of the electronic wiping of dust-sucking eraser effectively.But still have some deficits, it is little that it also is difficult to solve the wiping area, the problem that chalk dust disorderly flies.
The purpose of this utility model is to provide a kind of dust-free black board eraser.Little to solve the wiping area, the problem that chalk dust disorderly flies.
The purpose of this utility model is achieved in that the dust-free black board eraser of this utility model.Mainly constitute by time power rotating shaft, rope, wiping handle, snag, blackboard.Its time power rotating shaft, rope, blackboard are by selecting for use on the market.Its wiping handle is the type shape, uses wood material, through the planing operation manufacturing.Its snag is the character cut in bas-relief shape, uses the cotton wool material, through the weaving processing and manufacturing.Return the power rotating shaft and adopt the screw method to be installed in the position, upward top of blackboard, constitute isolating construction, function has been to fall the rope effect.Rope adopts spinning solution to be connected back the interior location of power rotating shaft, constitutes spiral-shaped syndeton, and function has been to draw the handle effect of wiping.Wipe handle and adopt system, method to be connected the other end position of rope, constitute bascule, function has been the effect of erasing the board.Snag adopts the cover method to be installed in the external position of wiping handle, constitutes the square configuration overall structure, and function has been the effect of erasing the board. so just realized the purpose of this utility model.
The advantage of utility model: big group of the cleaning device of the utility model and original blackboard or slabstone has the sucking chalk powder device technique to compare two advantages and improvement;
The first, because the utility model has designed time power rotating shaft in technical scheme, so the Convenient scrubber blackboard;
The second, because the utility model has designed the large tracts of land snag in technical scheme, so quick the wiping; Thereby it is little just more effectively to have solved the wiping area, the problem that chalk dust disorderly flies.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of dust-free black board eraser of the present utility model;
Fig. 2 is the wiping handle side-looking structural representation of dust-free black board eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 time power rotating shaft, 2 ropes 3 are wiped handle 4 snags 5 blackboards
In the optimum implementation of dust-free black board 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: as shown in the figure, dust-free black board eraser of the present utility model.Mainly constitute by time power rotating shaft 1, rope 2, wiping handle 3, snag 4, blackboard 5.Return power rotating shaft 1 and adopt the screw method to be installed in the position, upward top of blackboard 5, constitute isolating construction, function has been to fall the rope effect.Rope 2 adopts spinning solution to be connected back the interior location of power rotating shaft 1, constitutes spiral-shaped syndeton, and function has been to draw the handle effect of wiping.Wipe handle 3 and adopt system, method to be connected the other end position of rope 2, constitute bascule, function has been the effect of erasing the board.Snag 4 adopts the cover method to be installed in the external position of wiping handle 3, constitutes the square configuration overall structure, and function has been the effect of erasing the board.
Its dynamic structure: in force:
Its wiping handle 3 acts on blackboard 5 by snag 4, thereby finishes erasing the board of task.Its power rotating shaft 1 of returning acts on wiping handle 3 by rope 2, thereby finishes the task of receiving blackboard eraser.So just realized the purpose of this utility model.Thereby it is little just to have solved the wiping area, the problem that chalk dust disorderly flies.
Below by using method, the utility model is done more detailed description:
The dust-free black board eraser of this utility model is work like this:
In use, when erasing the board, leave behind and wipe handle 3.Its wiping handle 3 acts on blackboard 5 by snag 4, thereby finishes erasing the board of task.Its power rotating shaft 1 of returning acts on wiping handle 3 by rope 2, thereby finishes the task of receiving blackboard eraser.
Realize that preferred plan of the present utility model is is material with the cotton wool, utilize the basic equipment of blackboard eraser factory, take to produce by batch in small batches, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
