Description

A kind of band is from the blackboard wiping function and dust-collecting box
Technical field
The utility model relates to a kind of blackboard, and especially a kind of band is from the blackboard wiping function and dust-collecting box.
Background technology
Blackboard, concerning not strange everybody, especially concerning student and teacher, blackboard is almost study or the necessary article needed for teaching, every day, we will write to blackboard, and after full blackboard write in our word, erase the board and just become the thing of another people's headache, in the process erased the board, what chalk dust waftd is everywhere, teacher or classmate's association is inevitably made to suck chalk dust, affect healthy, moreover, erasing the board also to compare wastes time and energy, particularly in senior middle school, the every class of teacher all goes to erase the board with time a few minutes, therefore the quality time on classroom is wasted.
If there is a kind of blackboard, just the word on blackboard can be wiped in the process sliding up and down blackboard, eliminate the required time that erases the board, teacher also can make full use of the time impart knowledge of attending class, and improves classroom efficiency.
Utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of this utility model is to provide a kind of band from the blackboard wiping function and dust-collecting box, it adopts in blackboard frame, is provided with motor and chain, chain is provided with rub piece, rub piece is by blackboard, chain lifting drives rub piece to wipe blackboard up and down, and lower end is provided with dust-collecting box simultaneously.
The technical scheme adopted to realize the purpose of this utility model is: a kind of band, from the blackboard wiping function and dust-collecting box, is characterized in that: it is made up of blackboard frame, blackboard, rub piece, dust-collecting box, gear, chain, power transmission shaft, motor, power line and switch; Described blackboard frame inside is provided with gear, chain, power transmission shaft and motor, and front is provided with blackboard, rub piece and dust-collecting box; Described rub piece two ends are provided with chain; Described dust-collecting box one end through blackboard frame, and is provided with lid in outlet; Described gear has four, is distributed in the corner of blackboard frame; Described chain has two, each one of left and right, and two ends are provided with gear; Described power transmission shaft has three, is divided into a major axis and two minor axises; Described motor rotation axis place is provided with gear and major axis, and motor only has one; Described switch is located at metope.
The beneficial effects of the utility model are: the dust on blackboard can be wiped by automatically, laborsavingly again save time; And structure is simple, easy to use, practical.

Detailed description of the invention
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of band, from the blackboard wiping function and dust-collecting box, is characterized in that: it is made up of blackboard frame, blackboard, rub piece, dust-collecting box, gear, chain, power transmission shaft, motor, power line and switch; Described blackboard frame inside is provided with gear, chain, power transmission shaft and motor, and front is provided with blackboard, rub piece and dust-collecting box; Described rub piece two ends are provided with chain; Described dust-collecting box one end through blackboard frame, and is provided with lid in outlet; Described gear has four, is distributed in the corner of blackboard frame; Described chain has two, each one of left and right, and two ends are provided with gear; Described power transmission shaft has three, is divided into a major axis and two minor axises; Described motor rotation axis place is provided with gear and major axis, and motor only has one; Described switch is located at metope.
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, described blackboard frame is fixed on metope, and there is opening both sides, facilitates rub piece to move up and down; Described blackboard is embedded in blackboard frame; Described rub piece is close to blackboard, and two ends are stretched in blackboard frame and are connected with chain simultaneously, and rub piece moves up and down and can reach with blackboard friction the effect erased the board; Described dust-collecting box is located at below blackboard, is used for collecting the dust fallen down when erasing the board, and the lid simultaneously established through one end of blackboard frame can be opened, and conveniently cleans out the dust in control of dust; Described pinion rotation drives chain to rotate; Described power transmission shaft has two minor axises in blackboard frame lower end and fixes with it, centre is provided with gear, and gear can rotate around it, and upper end major axis connects two gears above, one end and motor share a gear simultaneously, and electric machine rotation driven gear rotates thus major axis other end gear and then rotates; When described direction of motor rotation changes, pinion rotation direction also can change, thus the rub piece be connected with chain can move up and down; Described power line connects motor and switch, connects external circuit by plug; Described switch is provided with two buttons, is respectively " liter " and " falling ", and during pressing " liter ", rub piece rises, and during pressing " falling ", rub piece declines.
When using the utility model, erase the board if want, then by " liter " that compress switch or " general ", after wiping clean blackboard, rub piece is moved to the top or bottom of blackboard, conveniently writes.
