Abstract
The invention provides a power-driven blackboard for teaching, which comprises an electromotor (8), a driving wheel (3), a driven wheel (4), a flexible blackboard (10), a word cleaning rolling brush (2), a dust removing brush (7), a frame (1), a panel (11), a change gear (12), a white board and a projector moving track, a transmission device, a maneuvering box and the like. The power-driven backboard has the advantages that the blackboard can be automatically cleaned, the projection is interactive and the dust and light pollution is avoided, and the integration of the power-driven blackboard and the projection interaction is realized; the continuous innovation of the power-driven blackboard is on the basis of the inventions with patent numbers of 03112751.7 and 200910029585.9; and the power-driven blackboard has the characteristics of emphasizing the optimization of product structures, intensifying the integral coordination of exteriors and interiors, promoting the combination property of products and laying a good foundation for volume production and marketing.
Description
Technical field
The present invention relates to the driven blackboard in the teaching equipment.
Background technology
Be 03112751.7 and 200910029585.9 driven blackboard and the practice implementing this patent and enter small batch trial produce from the patent No. of existing Chinese patent literature record, also exist deficiency, for example: when 1. removing the dust on the elasticity steel wire removing wiping word round brush in the powder vertical rod, the noise that produces is large, and more serious to the damage of wiping the word round brush at the process elastic force steel wire of removing; 2. the structure of outer cover and function are indefinite, and especially the mode that is connected and fixed of outer cover and framework is unsatisfactory, thereby directly have influence on quality, outward appearance and the production work efficiency of driven blackboard; 3. wiping the word round brush can not cycling and reutilization; 4. function singleness.
Summary of the invention
The present invention is exactly for a kind of new driven blackboard of the Design of Problems of above-mentioned existence, so reach that noise is little, function is many, quality better, outward appearance be beautiful, and lay a good foundation for batch production and listing.
Technical solution of the present invention:
1. designed a kind of dedust brush (7), the upper affixed bristle of dedust brush (7) is to be made by the hairbrush silk of wave-like, brushes dust on the word round brush (2) by dedust brush (7) bullet.
2. designed a kind of panel, it comprises panel (11) body, cover plate (21), slot cover (15), rail groove (17), wool top groove (18), multiplex hole (16), installing hole (19,20), by installing hole (19,20), realization connects with framework (1); By the wool top on the wool top groove (18), realize sound insulation and dust-separation; By rail groove (17), realize the movement of blank on rail groove (17); By multiplex hole (16), not only fixed end casing (14), also realized smooth firmly mutually the leaning on of panel (11) with panel (11) binding site; By cover plate (21) is pressed in the slot cover (15), outward appearance and dismounting requirement have been satisfied; By panel (11) is designed to elongate in shape, realized general and exchange; By backing plate (9) supporting flexible blackboard (10); The bottom of driven blackboard is provided with grey box (6) and pencil box (5).
3. by fine setting screw rod (13), regulate driving wheel (3) and the fitness of wiping word round brush (2), reduce initial mated condition between wiping word round brush (2) and the driving wheel (3), realized the cycling and reutilization of wiping word round brush (2).
4. cooperate with flexible rail on the flexible blackboard (10) by change gear (12), realized the steady-state operation of flexible blackboard (10).
5. by the top at driven blackboard projector's moving track is set, has realized that driven blackboard and projection interaction are integrated.
Beneficial effect of the present invention:
The present invention is to be that the basis of 03112751.7 and 200910029585.9 driven blackboard continues innovation in the patent No., go the powder structure by optimizing the wiping word, reduced noise, prolonged service life, Combination application by change gear (12), strengthened reliability of operation, by having designed panel (11), strengthened the external and inherent Total tune of product, by blank and projector's moving track are set, realized that driven blackboard and projection interaction are integrated, and promoted the combination property of product, for the batch production and listing lay a good foundation.

The specific embodiment
Below in conjunction with accompanying drawing the present invention and implementation are described further:
Referring to accompanying drawing, motor (8) is passed to power and is wiped word round brush (2), wiping word round brush (2) directly leans against on the driving wheel (3), the upper cover of driving wheel (3) has flexible blackboard (10), both do relative brushing rotation, writing on the flexible blackboard (10) is wiped word round brush (2) and is wiped, and wipes the dust of being stained with knot on the word round brush (2) and is removed by the brush of the bristle bullet on the dedust brush (7).Bristle on the dedust brush (7) is to be made by the hairbrush silk of wave-like, and this point is very important, and its permeability is good, resistance is little, good springiness, noise is low, little to the wearing and tearing of wiping word round brush (2), installation and debugging are very simple.Designed a kind of panel, it comprises panel (11) body, cover plate (21), slot cover (15), rail groove (17), wool top groove (18), multiplex hole (16), installing hole (19,20), by installing hole (19,20), realization connects with framework (1).By the wool top on the wool top groove (18), sound insulation and dust-separation have been realized.By rail groove (17), realized the movement of blank on rail groove (17).By multiplex hole (16), not only fixed end casing (14), also realized smooth firmly mutually the leaning on of panel (11) with panel (11) binding site.By cover plate (21) is pressed in the slot cover (15), outward appearance and dismounting requirement have been satisfied.By panel (11) is designed to elongate in shape, also realized general and exchange, reduced cost, improved efficient.Cooperate with flexible rail on the flexible blackboard (10) by change gear (12), realized the steady-state operation of flexible blackboard (10).By fine setting screw rod (13), regulate the fitness between driving wheel (3) and the wiping word round brush (2), reduce initial mated condition between wiping word round brush (2) and the driving wheel (3), realized the cycling and reutilization of wiping word round brush (2).By backing plate (9) supporting flexible blackboard (10).By the top at driven blackboard projector's moving track is set, has realized that driven blackboard and projection interaction are integrated.The bottom of driven blackboard is provided with grey box (6) and pencil box (5).Many apparent things are not just given unnecessary details here.
