[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-6The utility model discloses a kind of propaganda display devices, including backboard 1 and the cover 2 of installation in the front of backboard 1, the bottom of backboard 1 is provided with support frame 10, gap 3 is equipped between backboard 1 and cover 2, the inside of gap 3 is used to install propaganda newspaper 4, the both sides of cover 2 are provided with the opening of intercommunication with gap 3 and for propaganda newspaper 4 to pass through, the both sides of backboard 1 are provided with mounting bracket 5, the rotatable mounting of two sides mounting bracket 5 is equipped with scroll 6, the rotatable mounting of each scroll 6 is equipped with crank 9, for rotating scroll 6, the rotatable mounting of two sides scroll 6 is equipped with same connection belt 7, connection belt 7 is flexible and bendable material, one side of connection belt 7 is wound on a scroll 6, the other side of connection belt 7 is wound on another scroll 6, when disassembling and assembling propaganda newspaper 4, hand rotates crank 9 to drive scroll 6 to rotate to drive connection belt 7 to move, to synchronously drive the propaganda newspaper 4 connected with connection belt 7 to pass through gap 3.

[0025] In actual operation, the connection between the connection belt 7 and the propaganda newspaper 4 can be connected by using a clip, and the connection between the connection belt 7 and the propaganda newspaper 4 can also be connected by using a sticky glue 8, a tape, a double-sided tape, etc.

[0026] In order to improve the sealing performance of the cover 2, the opening on the both sides of the cover 2 is detachably mounted with a plugging member 11, and the plugging member 11 is used to block the opening to improve the sealing performance of the cover 2.

[0027] In summary, when the propaganda newspaper 4 is disassembled and assembled, the propaganda newspaper 4 is connected with the connection belt 7, the crank 9 is held by hand, and the crank 9 is rotated clockwise or counterclockwise, and the crank 9 drives the scroll 6 connected therewith to rotate. Since the scroll 6 is closely connected with the connection belt 7, the rotation of the scroll 6 drives the connection belt 7 to move.
