Description
The utility model relates to Convenient blackboard and wipes.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, the technology about the sucking chalk powder device is arranged existing and that once had was all done very fruitful effort to the demand that makes things convenient for blackboard eraser, also once designed many outstanding technical schemes.As being declared by Wang Juncheng of the Decree of Patent Office of China in 1996, Granted publication number is CN2235905Y, and China Patent No. (ZL) is: No. 95225177.9 utility model title is the utility model patent of " dust absorption blackboard eraser ", the technical scheme that is adopted.Having aspect the sucking chalk powder device technique is a routine of great value invention, and it has solved the problem of blackboard eraser dust suction effectively.But still have some deficits the problem that blackboard eraser was wasted time and energy before it also was difficult to solve.
The purpose of this utility model is to provide a kind of Convenient blackboard to wipe.To solve the problem that former blackboard eraser is wasted time and energy.
The purpose of this utility model is achieved in that this utility model Convenient blackboard wiping.Mainly constitute by blackboard frame, motor, pulley, top shoe, last slide rail, rope, blackboard eraser, axle, sliding block, glidepath, motor.Its motor, rope, axle are by selecting for use on the market.Its pulley is round-shaped, uses plastic material, through the thermoforming processing and manufacturing.Its top shoe, sliding block are square shapes, use plastic material, through the thermoforming processing and manufacturing.Last slide rail adopts adhesive method to be installed in the upper position of blackboard frame, constitutes the square shape draw bail, and function is to play the guiding role.Glidepath adopts adhesive method to be installed in the lower position of blackboard frame, constitutes the square shape draw bail, and function is to play the guiding role.Motor adopts welding method to be installed in the tip position of axle, constitutes the cylindrical shape draw bail, and function is the action usefulness that runs up.Pulley adopts clearance fit method to be installed in the upper position of axle, constitutes the cylindrical shape draw bail, and function has been an anastomosis.Top shoe adopts clearance fit method to be installed in the upper position of axle, constitutes the cylindrical shape draw bail, and function is to play a supportive role.Blackboard eraser adopts the interference fit method to be installed in the medium position of axle, constitutes the cylindrical shape draw bail, and function has been the effect of erasing the board.Rope adopts fastens the right positions that method is installed in pulley, constitutes the linear shape draw bail, and function has been a pulling function.Rope adopts fastens the shaft position that method is installed in motor, constitutes the linear shape draw bail, and function has been a pulling function.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 sucking chalk powder device technique that has;
The first, because the utility model has designed motor in technical scheme, so blackboard eraser is rotatable;
The second, because the utility model has designed slide rail in technical scheme, so can realize the blackboard eraser translation; Thereby just can more effectively solve the problem that former blackboard eraser is wasted time and energy.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram that the utility model Convenient blackboard is wiped;
The numbering of parts explanation in the schematic diagram: 89 sliding blocks of slide rail 6 rope 7 blackboard erasers, 10 glidepaths, 11 motors on 1 blackboard frame, 2 motors, 3 pulleys, 4 top shoes 5
In the optimum implementation that the utility model Convenient blackboard is wiped, 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, the utility model Convenient blackboard is wiped.Mainly constitute by blackboard frame 1, motor 2, pulley 3, top shoe 4, last slide rail 5, rope 6, blackboard eraser 7, axle 8, sliding block 9, glidepath 10, motor 11.Last slide rail 5 adopts adhesive method to be installed in the upper position of blackboard frame 1, constitutes the square shape draw bail, and function is to play the guiding role.Glidepath 10 adopts adhesive method to be installed in the lower position of blackboard frame 1, constitutes the square shape draw bail, and function is to play the guiding role.Motor 2 adopts welding method to be installed in the tip position of axle 8, constitutes the cylindrical shape draw bail, and function is the action usefulness that runs up.Pulley 3 adopts clearance fit method to be installed in the upper position of axle 8, constitutes the cylindrical shape draw bail, and function has been an anastomosis.Top shoe 4 adopts clearance fit method to be installed in the upper position of axle 8, constitutes the cylindrical shape draw bail, and function is to play a supportive role.Blackboard eraser 7 adopts the interference fit method to be installed in the medium position of axle 8, constitutes the cylindrical shape draw bail, and function has been the effect of erasing the board.Rope 6 adopts fastens the right positions that method is installed in pulley 3, constitutes the linear shape draw bail, and function has been a pulling function.Rope 6 adopts fastens the shaft position that method is installed in motor 11, constitutes the linear shape draw bail, and function has been a pulling function.
Its dynamic structure: in force:
According to the translation principle, its top shoe 4 acts on blackboard frame 1 by last slide rail 5, thereby finishes the task of top shoe translation.According to rotary principle, its motor 2 acts on blackboard eraser 7 by axle 8, thereby finishes the task that blackboard eraser rotates.So just realized the purpose of this utility model.Thereby just can solve the problem that former blackboard eraser is wasted time and energy.
Below by using method, the utility model is done more detailed description:
It is work like this that this utility model Convenient blackboard is wiped:
In use, when using this novel, at first starter motor 2, make axle 8 rotations, and then driving blackboard eraser 7 rotations, starter motor 11 then, drive rope 6 and move right, thereby pulling pulley 3 moves right, realize blackboard eraser 7 to right translation, so just can rapidly blackboard eraser be tried totally.
In use, when using this novel, if do not adopt the motor-driven function, can wipe 7 with the direct mobile blackboard of hand and wipe the trial work work, effect is also fine, but efficient is low, the dust that wiping tries is all concentrated and is cleared up, to keep the neat and tidy in classroom.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of plastic processing factory, take thermoforming to produce in batch, the demand with supply consumption circle so just can realize practical value of the present utility model and economic worth better.
