Abstract

The utility model is an electric lifting blackboard, relating to the improvement of the lifting blackboard structure. The utility model is to solve the problem of uneasy operation of the prior lifting blackboard, and provide an electric lifting blackboard with easy operation and simple structure. The utility model comprises a frame (1) which is internally provided with a top blackboard (4) and a bottom blackboard (3) which can move up and down, whose structure point is that the two sides of the top blackboard (4) and the bottom blackboard (3) are respectively arranged on a driven chain wheel (13) through a same chain (12), the driven chain wheel (13) realizes connection with the driving chain wheel (15) on the electric motor (16) by use of the chain (14).

Description

A kind of electric up-down blackboard
Technical field:
The utility model relates to the improvement of blackboard movable up and down structure.
Background technology:
Existing blackboard movable up and down is to rely on manual pulling cotton rope fully, and two blackboards are gone here and there mutually, but operation inconvenience, and slow motion, has influenced the continuity of education activities.
The utility model content:
The utility model is exactly to solve the present unhandy problem of blackboard movable up and down, and a kind of electric up-down blackboard easy and simple to handle, simple in structure is provided.
The utility model adopts following technical scheme: the utility model comprises framework, have the last blackboard that to go here and there up and down, following blackboard in the framework, its structural feature is that the both sides of going up blackboard, following blackboard are arranged on one by on the movable sprocket by same chain respectively, is linked to each other with the drive sprocket on the motor by chain by movable sprocket.
The beneficial effects of the utility model:
Because upward blackboard of the present utility model, following blackboard are arranged on one by on the movable sprocket by same chain respectively, linked to each other with the drive sprocket on the motor by chain by movable sprocket, therefore, just pass through starter motor, just can finish moving up and down of two blackboards, make it simple to operate, blackboard can faster move, and is beneficial to the continuity of teaching.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A enlarged drawing of Fig. 1;
Fig. 4 is the B-B enlarged drawing of Fig. 1;
Fig. 5 is that the C portion of Fig. 1 is to view.
The specific embodiment:
The utility model comprises framework 1, have the last blackboard 4 that to go here and there up and down, following blackboard 3 in the framework 1, the both sides of last blackboard 4, following blackboard 3 are arranged on one by on the movable sprocket 13 by same chain 12 respectively, are linked to each other with the drive sprocket on the motor 16 15 by chain 14 by movable sprocket 13.
The side of last blackboard 4, following blackboard 3 is provided with the slideway 11 that places framework 1, pulley 10, the pulley 8 in the slideway 9, guarantees blackboard 4, the normal operation of blackboard 3 down with this.
For making the utility model device be convenient to straighforward operation, also can in framework 1, be respectively arranged with receiver of remote-control sytem 6, the lifting controller 7 that to purchase from the market.
The side of framework 1 is provided with appliance controling plate 2, and framework 1 top is provided with limit switch 5.
Below in conjunction with a description of drawings course of action of the present utility model:
At first, start the switch 17 on the appliance controling plate 2, motor 16 actions, drive sprocket 15 drives by chain 14 and is rotated by movable sprocket 13, is just rotated by the chain on it 12 by the rotation of movable sprocket 13, and chain 12 just drives goes up blackboard 4, the motion of blackboard 3 down.When having a power failure, also can be by manual chain 12, drive by last blackboard 4, blackboard 3 synchronous operations down on movable sprocket 13 rotations, the chain 12.
