Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, in the embodiment of the utility model, the double-screen interactive blackboard comprises a blackboard main body 2, an L-shaped support 7 is arranged above the blackboard main body 2, a sweeping board 6 is rotatably arranged below one side of the L-shaped support 7 close to the front surface of the blackboard main body 2, a driving device capable of driving the L-shaped support 7 to reciprocate is arranged behind the blackboard main body 2, when the driving device reciprocates, the L-shaped support 7 can be driven to reciprocate, so that the sweeping board 6 reciprocates, and when the driving device reciprocates, the sweeping board 6 can sweep dust from the blackboard main body 2;

in order to avoid occupying the space of the blackboard main body 2 when the cleaning plate 6 is not used, a support shaft 8 is fixed at the power output end of the driving device, one end of the L-shaped support 7 close to the rear side of the blackboard main body 2 is rotatably connected with the support shaft 8, when the cleaning plate is not used, according to the modes of figures 5, 6 and 7, the L-shaped support 7 is firstly rotated to one side of the blackboard main body 2, and then the L-shaped support 7 is moved to the position gradually close to the blackboard main body 2 through the driving device so as to hide the side surface;

as shown in fig. 1, in order to enable the driving device to drive the L-shaped bracket 7 to reciprocate, in this embodiment, preferably, the driving device includes mounting plates 1 fixed on both sides of the rear surface of the blackboard main body 2, a screw rod 4 rotatably mounted between the two mounting plates 1, and a nut 9 screwed outside the circumference of the screw rod 4, the lower end of the supporting shaft 8 is fixedly connected with the nut 9, and the upper end of the supporting shaft 8 is rotatably connected with the L-shaped bracket 7, that is, when the screw rod 4 rotates, the nut 9 can be driven to reciprocate, and the nut 9 can be driven to reciprocate to drive the L-shaped bracket 7 to reciprocate, thereby realizing the reciprocating motion of the cleaning plate 6;
