Abstract
The utility model provides an automatic erasing device for a blackboard. The automatic erasing device for the blackboard can erase handwriting on the blackboard quickly and cleanly so that environmental pollution caused by chalk dust is reduced. The automatic erasing device for the blackboard is convenient to use and reasonable in structure. One end of the blackboard is provided with an electrical machine. An output shaft of the electrical machine is connected with a gear of the electrical machine. The other end of the horizontal direction of the electrical machine is provided with a driven gear. And the gear of the electrical machine is connected with the driven gear through a chain. The automatic erasing device for the blackboard also comprises a driving gear and a slide block which is arranged perpendicularly to the driving gear. The driving gear is connected with the slide block through a central shaft. A through hole which is used for the central shaft to pass is arranged at the center of the slide block. A hairbrush is fixed on the outer surface of the central shaft. And the driving gear is meshed with the chain. The automatic erasing device for the blackboard can be arranged during the process of manufacturing the blackboard or on the blackboard which is in use, is easy to mount, environmental-friendly and convenient.
Description
Technical field
The utility model relates to a kind of device that erases the board.
Background technology
When existing chalkboard eraser was used to erase the board, speed was slow, and efficient is low; Even electric blackboard eraser also can not be wiped the person's handwriting on the blackboard because of its area coverage is little fast neatly, dust can appear; Dust not only has pollution to environment, and healthy influential to indoor occupant.
Summary of the invention
The purpose of the utility model provides a kind of blackboard and clashes device automatically, can totally clash the person's handwriting on the blackboard fast, reduces the pollution of chalk dust to environment, and is easy to use, rational in infrastructure.
Said purpose realizes through following scheme:
A kind of blackboard clashes device automatically, and blackboard one end is installed motor, and the output shaft of motor is connected with motor gear, is connected through chain between the other end installation driven gear of said blackboard horizontal direction, said motor gear and driven gear; Also comprise driving gear and the slide block that is provided with the driving gear vertical direction, be connected through central shaft between said driving gear and slide block that said slide block center is provided with the through hole that the confession central shaft passes through, said central shaft outer surface is fixed with hairbrush; Said driving gear and chain engages.
Said slide block place driving gear under, said blackboard bottom is provided with guide rail, said slide block and guide rail are slidingly connected.
Said hairbrush is provided with at the central shaft outer surface twist.
Hair on the said hairbrush is obliquely installed downwards.
Said hairbrush below is provided with the dust collection groove of slightly being longer than the hairbrush cross-sectional diameter, and said dust collection groove is fixedly connected with slide block.
The utility model can be installed when making blackboard, also can install the blackboard in the use, and is easy for installation, environmental protection, facility.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Wherein, motor 1, motor gear 2, driven gear 3, chain 4, driving gear 5, slide block 6, central shaft 7, hairbrush 8, guide rail 9, blackboard 10, dust collection groove 11.
The specific embodiment:
Set forth the utility model in detail preferred embodiment below in conjunction with accompanying drawing.
A kind of blackboard clashes device automatically; With reference to Fig. 1, an end of blackboard 10 is installed motor 1, and the output shaft of motor 1 is connected with motor gear 2; The other end of said blackboard 10 horizontal directions is installed driven gear 3, is connected through chain 4 between said motor gear 2 and the driven gear 3; Also comprise driving gear 5 and the slide block 6 that is provided with driving gear 5 vertical direction; 6 of said driving gear 5 and slide blocks are connected through central shaft 7; The center of said slide block 6 is provided with the through hole that supplies central shaft 7 to pass through, and said central shaft 7 can freely rotate in the centre bore of driving gear 5 and in the through hole of slide block 6; Said central shaft 7 outer surfaces are fixed with hairbrush 8; Said driving gear 5 and chain 4 engagements.Said slide block 6 place driving gear 5 under, the bottom of said blackboard 10 is provided with guide rail 9, said slide block 6 places on the guide rail 9 and with guide rail 9 and is slidingly connected.
During work, motor gear drives the chain rotation, and chain drives driving gear 5 parallel the moving with its engagement, and driving gear rotates through central shaft drive hairbrush and moves by horizontal direction simultaneously, can realize the wiping examination to blackboard.Said hairbrush 8 the central shaft outer surface be provided with twist and hairbrush on the hair be obliquely installed downwards, can the dust of wiping be promoted to fall naturally like this; Below hairbrush 8, be provided with the dust collection groove 11 of slightly being longer than the hairbrush cross-sectional diameter, said dust collection groove 11 is fixedly connected with slide block 6.
This embodiment is the protection domain that the exemplary illustration of this patent is not limited it; Those skilled in the art can also carry out the part to it and change; The short of spirit that exceeds this patent all is regarded as the replacement that is equal to this patent, all within the protection domain of this patent.
