[0019] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 4 The utility model provides a campus safety education publicity display stand, including a support frame 1 arranged on the left and right sides and a mounting beam arranged at the upper and lower ends, the mounting beam is located at the upper and lower parts of the support frame 1, the support frame 1 and the mounting beam are connected to each other to form a rectangular display stand, a display board 4 is arranged in front of the mounting beam, a lifting assembly for driving the display board 4 to move up and down is arranged between the mounting beams, a driving assembly for driving the lifting assembly to work is arranged in the mounting beam, the display board 4 is used to paste publicity documents or draw publicity content, the lifting assembly can be driven to work by the driving assembly, and the lifting assembly drives the display board 4 to move up and down, when it is necessary to clean or modify the content, the display board 4 can be lowered to a suitable height, and the operator can stand on the ground to operate the display board 4 without the help of climbing tools; when the display board 4 is cleaned or modified, the display board 4 is raised again, so that teachers, students and parents can browse the publicity content displayed in the school.

[0021] The lifting assembly includes a guide rail 5, a lifting screw 6 and a lifting block 7. The guide rail 5 is arranged on both sides of the mounting beam, and both ends of the guide rail 5 are fixedly connected to the mounting beam. The lifting screw 6 is arranged inside the guide rail 5, and both ends of the lifting screw 6 are rotatably connected to the mounting beam. The center of the lifting block 7 is threadedly connected to the lifting screw 6, and the outer wall of the lifting block 7 is slidably connected to the guide rail 5. The rear end of the display board 4 is fixedly connected to the lifting block 7, and the lifting screw 6 is connected to the driving assembly. The lifting screws 6 on both sides are driven to rotate synchronously through the driving assembly. Under the action of the lifting screw 6, the lifting block 7 makes a linear motion upward or downward along the guide rail, thereby driving the display board 4 to rise or fall.

[0022] The driving assembly includes a power component and a transmission component. The mounting beam includes an upper top beam 2 and a lower bottom beam 3 . The power component is arranged inside the bottom beam 3 , and the transmission component is arranged inside the top beam 2 .

[0023] The power component includes a vertically installed worm wheel 8 and a horizontally installed worm 9. A driving cavity is provided inside the bottom beam 3. The worm wheel 8 and the worm 9 are rotatably connected to the inner walls of the driving cavity respectively. The worm wheel 8 is coaxially connected to any of the lifting screws 6. The worm wheel 8 is meshingly connected to the worm 9. A hand crank 10 is rotatably installed on the side wall of the support frame 1. The hand crank 10 is coaxially connected to the worm 9 through a connecting rod.

[0024] The transmission component includes a transmission wheel 11 and a transmission chain 12. A transmission cavity is provided inside the top beam 2. The transmission wheels 11 are provided on both sides of the transmission cavity. The transmission wheels 11 are rotatably connected to the inner wall of the transmission cavity. The transmission wheels 11 are coaxially connected one-to-one with the lifting screws 6 on both sides. The transmission wheels 11 are connected to each other through the transmission chain 12.

[0025] Since the hand crank 10 and the bottom beam 3 are at the same height, in order to facilitate the rotation of the hand crank 10, the position of the bottom beam 3 can be flush with the waist of an adult. The worm 9 is driven by the worm gear 8 to rotate, and the tops of the lifting screws 6 on both sides are connected to each other through the transmission sprocket and the transmission wheel 11. Therefore, when one lifting screw 6 rotates, the other lifting screw 6 will also rotate synchronously under the action of the transmission parts, so as to drive the lifting block 7 and the display board 4 to rise or fall. The lifting block 7 is located at the back center of the display board 4, and the display board 4 is located in front of the mounting beam. Therefore, when the display board 4 is lifted, it will not collide with the mounting beam, and the mounting beam will not affect the lifting of the display board 4. Only when the lifting block 7 abuts against the mounting beam, the height of the display board 4 will be limited. Therefore, even if the height of the bottom beam 3 is at the position of the adult's waist, when the display board 4 drops to the lower limit, the center of the display board 4 is also at the position of the adult's waist. The operator can perform all-round operation on the display board 4 while standing on the ground, eliminating the safety hazards caused by high-altitude operations.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
