Example 1

As shown in fig. 1-5, an interactive teaching blackboard for a smart classroom comprises a frame body 1, an inner plate 11 and an outer plate 12 which are slidably connected to the inner side wall of the frame body 1, a display screen 13 is arranged at the upper half part of the inner side area of the frame body 1, side plates 14 with racks 15 are arranged on the side surfaces of the inner plate 11 and the outer plate 12, a vertical plate 27 is arranged inside the frame body 1, two gear cylinders 26 which are connected end to end are rotatably arranged between the vertical plate 27 and the side wall of the frame body 1 through a turntable bearing 29, tooth grooves are formed in the inner wall and the outer wall of each gear cylinder 26, two racks 15 are respectively meshed with the outer tooth grooves of the two gear cylinders 26 from two directions, the inner walls of the two gear cylinders 26 are meshed with the same outer gear 25, wherein the outer gear 25 is coaxially connected with an inner tooth post 24.

When not using display screen 13, this blackboard is upper and lower double-deck over-and-under type blackboard, constitute by inner panel 11 and planking 12, the blackboard that is located the bottom supplies the teacher to write on the blackboard, when the blackboard of bottom is full, it risees through motor 22 drive, the blackboard of eminence descends simultaneously, supply the teacher to continue to write on the blackboard, when needs use display screen 13, the blackboard is written on through planking 12 of bottom, inner panel 11 descends and hides in planking 12 rear, expose display screen 13, the blackboard that sets up upper and lower floor can extend to the eminence with writing the scope, greatly increased the area of blackboard.

The inner tooth column 24 and the outer gear 25 are fixedly connected through a shaft rod, the output end of the motor 22 is provided with a driving gear 23 which is connected with the inner tooth column 24 in a sliding mode and meshed with each other, the inner tooth column 24 and the outer gear 25 are used for transmission, the outer gear 25 is correspondingly meshed with tooth grooves in the inner walls of the two gear cylinders 26, and the outer gear 25 is connected in the tooth grooves in a sliding mode.

When the outer gear 25 is located between the two gear cylinders 26, the rotation of the outer gear can drive the two gear cylinders 26 to rotate at the same time, and the racks 15 corresponding to the two gear cylinders 26 move up and down, so that the inner plate 11 and the outer plate 12 synchronously move in opposite directions, and when the outer gear 25 is only meshed with the gear cylinder 26 corresponding to the inner plate 11, the outer gear 25 only drives the inner plate 11 to move down, so that the inner plate and the outer plate are overlapped, and the display screen 13 is exposed.

The two gear cylinders 26 are connected end to end through the turntable bearing 29 in a rotating mode, the turntable bearing 29 is connected to the surface of the side wall of the frame body 1 in a rotating mode, and the two gear cylinders 26 can be better used through the turntable bearing 29.

The outer surface of interior tooth post 24 rotates and is connected with ring or rolling bearing, and ring or rolling bearing's outer wall is equipped with driving lever 28, and motor 22 passes through shell 21 to be fixed in the outside surface of framework 1, and driving lever 28 extends the surface of shell 21, is equipped with on the shell 21 with driving lever 28 front and back slip direction assorted spout, and spout restriction driving lever 28 is controlled and is reciprocated, sets up driving lever 28 and can make things convenient for the slip driving medium, makes outer tooth post 25 remove.

The implementation mode is specifically as follows: when the display screen 13 is not used, the blackboard is a common upper-lower double-layer lifting blackboard in the market, the blackboard is driven to move up and down through the rack 15 and the gear cylinders 26, the blackboard at the lower part is driven to lift through the motor 22, meanwhile, the blackboard at the higher part falls, and the blackboard at the higher part and the blackboard at the lower part synchronously and reversely move, so that the writing space of the blackboard writing is greatly improved, when the display screen 13 needs to be used, the deflector rod 28 is pushed towards the direction of the motor 22, the deflector rod 28 drives the inner tooth posts 24 to slide towards the direction of the motor 22, the outer gear 25 originally meshed with the two gear cylinders 26 slides towards the outer side and is only meshed with the gear cylinders 26 corresponding to the inner plate 11, when the motor 22 drives the driving gear 23 to rotate, the inner plate 11 slowly descends and is hidden behind the outer plate 12, so that the display screen 13 is exposed.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
