Description
The utility model relates to a kind of novel board erasing device.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, the big class of office appliance is write or drawing article, writes or drawing article, the assistant product group of writing or draw has the blackboard of sucking chalk powder device or the cleaning device technical group field of slabstone.Be numbered B43L 29/02.
At present, the technology about the cleaning device of blackboard that the sucking chalk powder device is arranged or slabstone existing and that once had was all done very fruitful effort to the demand of novel board erasing device, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Zhang Zhongmo, Granted publication number is CN2232850Y, China Patent No. (ZL) is: No. 95237145.6 utility model title is the utility model patent of " electric dust-proof blackboard eraser ", the technical scheme that is adopted.Cleaning device technical elements at blackboard that the sucking chalk powder device is arranged or slabstone is a routine of great value invention, and it has solved the problem of blackboard eraser electric dust-proof effectively.But still have some deficits, it also is difficult to solve when wiping wall extremely require great effort, and sawed-off people is inconvenience more, and make the problem of sweeping people's fatigue easily.
The purpose of this utility model is to provide a kind of novel board erasing device.Extremely require great effort when wiping wall to solve, sawed-off people is inconvenience more, and make the problem of sweeping people's fatigue easily.
The purpose of this utility model is achieved in that a kind of novel board erasing device of this utility model.Mainly constitute by iron nail, fixed bar, pull rope, rectangular groove, cloth, staple.Its major part pull rope, iron nail are by selecting for use on the market.Its rectangular groove is an elongate in shape with holes, makes material with timber, through the machined manufacturing.Its cloth is an elongate in shape, makes material with cloth, through the machined manufacturing.The cloth strip adoption assemble method of its strip shape is installed on the rectangular groove of elongate in shape with holes, the pull rope of its linear shape adopts assemble method to be installed on the rectangular groove of elongate in shape with holes, the fixed bar of its stock shape adopts assemble method to be installed on the iron nail, its rectangular groove acts on the wall by cloth, thereby make the requirement of this novel satisfied wiping wall, its pull rope acts on rectangular groove by fixed bar.Thereby make a novel task of wiping wall up and down of finishing.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with the original blackboard that the sucking chalk powder device is arranged or the cleaning device technology of slabstone;
The first, because the utility model has designed rectangular groove in technical scheme, so solved the fixing problem that forms the mop shape of cloth;
The second, because the utility model has designed pull rope in technical scheme, the problem that cloth moves up and down so solved rectangular troughed belt;
The 3rd, because the utility model has designed cloth in technical scheme, so solved the problem of wiping the dust on the wall.Thereby extremely require great effort in the time of just more effectively having solved the wiping wall, sawed-off people is inconvenience more, and make the problem of sweeping people's fatigue easily.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of a kind of novel board erasing device of the utility model;
Fig. 2 is the rectangular groove master TV structure schematic diagram of a kind of novel board erasing device of the utility model;
The numbering of parts explanation in the schematic diagram: 1 iron nail, 2 fixed bars, 3 pull ropes, 4 rectangular groove 5 cloths 6 staples
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of novel board erasing device of the utility model.Mainly constitute by iron nail 1, fixed bar 2, pull rope 3, rectangular groove 4, cloth 5, staple 6.Its major part pull rope 3, iron nail 1 are by selecting for use on the market.Its rectangular groove 4 is elongate in shape with holes, makes material with timber, through the machined manufacturing.Its cloth 5 is elongate in shape, makes material with cloth, through the machined manufacturing.The cloth 5 of its strip shape adopts assemble method to be installed on the rectangular groove 4 of elongate in shape with holes, the pull rope 3 of its linear shape adopts assemble method to be installed on the rectangular groove 4 of elongate in shape with holes, the fixed bar 2 of its stock shape adopts assemble method to be installed on the iron nail 1, its rectangular groove 4 acts on the wall by cloth 5, thereby make the requirement of this novel satisfied wiping wall, its pull rope 3 acts on rectangular groove 4 by fixed bar 2.Thereby make a novel task of wiping wall up and down of finishing.So just realized the purpose of this utility model.Thereby extremely require great effort in the time of just having solved the wiping wall, sawed-off people is inconvenience more, and make the problem of sweeping people's fatigue easily.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if before wiping wall, can enter rectangular groove 4 to cleaning liquid by the hole, makes cloth 5 be stained with cleaning liquid, increases cleaning performance.
Embodiment 2, in force, if when wiping wall, pulling traction rope 3, it is drawing rectangular groove 4 then around fixed bar 2, is being with cloth 5 to move upward, and arrives topmost by the time, loosens pull rope 3 and allows rectangular groove 4 move downward, and finishes the task of wiping wall up and down.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with timber, utilize the basic equipment of machined factory, take assembling to produce by batch, the demand with supply daily life circle so just can realize practical value of the present utility model and economic worth better.
