Through the arrangement of the casing 4 and the protective plate 7, the protection of the speakers 6 can be achieved to prevent the speakers 6 from being hit and being exposed to a large amount of dust in the air when the speakers 6 are not in use, which affects the normal use of the speakers 6. The situation of use occurs, shortening the time that the speaker 6 is exposed to the air, and solving the problem that the speaker of the multimedia display device in the prior art has no protective device, and a large amount of dust will be attached to the output end when exposed to the air for a long time, affecting the normal use of the speaker. By setting the pushing component, the height of the speaker 6 can be adjusted, which is convenient for pushing the speaker 6 out of the inner cavity of the casing 4 and storing it in the inner cavity of the casing 4. The operation is simple and easy to use. By setting the lifting component, the height adjustment of the fixed plate 2 and the display screen 3 can be achieved, which is convenient for the user to adjust the height of the display screen 3 according to the actual use situation, thereby improving the flexibility of the device when in use. Small blocks are respectively arranged on the left and right sides of the top of the inner cavity of the casing 4, and the setting of the small blocks prevents the lifting plate 5 from detaching from the inner cavity of the casing 4 during the rising process, thereby improving the stability of the device when in use.

[0022] In this embodiment, wheels 8 are provided at the four corners of the bottom end of the base 1. The wheels 8 are self-locking universal wheels, which can facilitate the movement of the device and further facilitate the transfer of the device, thereby improving the convenience of the device when in use.

[0023] In this embodiment, the lifting assembly includes a second motor 16, a screw 17, a moving cylinder 18 and a telescopic rod 19. The second motor 16 is arranged on one side of the top of the base 1, and the screw 17 is fixedly connected to the output end of the second motor 16. The moving cylinder 18 is screwed to the outer wall of the screw 17 and is fixedly connected to the bottom end of the fixed plate 2. The two telescopic rods 19 are both arranged on the top of the base 1 and are fixedly connected to the bottom end of the fixed plate 2. The second motor 16 is started to drive the screw 17 to rotate. Under the action of the rotational force of the outer wall thread of the screw 17, when the screw 17 rotates, the moving cylinder 18 can push the fixed plate 2 and the display screen 3 to slide up and down along a straight line under the limiting action of the two telescopic rods 19, so that the height of the fixed plate 2 and the display screen 3 can be adjusted, which is convenient for the user to adjust the height of the display screen 3 according to the actual usage, thereby improving the flexibility of the device when in use.

[0024] In this embodiment, the pushing assembly includes a first motor 9, a screw rod 10, a slider 11, a fixed seat 12, a connecting rod 13 and a limit assembly. The first motor 9 is arranged at the right end of the casing 4, and the output end of the first motor 9 extends to the inner cavity of the casing 4. One end of the screw rod 10 is rotatably connected to the left side of the inner cavity of the casing 4 through a bearing, and the other end of the screw rod 10 is fixedly connected to the output end of the first motor 9. The two sliders 11 are respectively screwed on the left and right sides of the outer wall of the screw rod 10. The fixed seat 12 is arranged at the bottom end of the lifting plate 5. One end of the two connecting rods 13 is respectively hinged at the top of the two sliders 11, and the other ends of the two connecting rods 13 are respectively hinged at the fixed seat 1 2, the limit assembly is arranged at the bottom end of the inner cavity of the casing 4 and is fixedly connected with the bottom ends of the two sliders 11 respectively. When the speaker 6 needs to be used, the first motor 9 is started to make the first motor 9 drive the screw rod 10 to rotate, so that the threads opposite to each other on the left and right sides of the outer wall of the screw rod 10 generate relative thread rotation force, so that the two sliders 11 slide toward the middle of the screw rod 10 at the same time under the limiting action of the limit groove 14 and the limit block 15, so that the two connecting rods 13 push the fixed seat 12, the lifting plate 5 and the speaker 6 to slide upward along the inner wall of the casing 4, so that the speaker 6 extends out of the inner cavity of the casing 4, which is convenient for the use and storage of the speaker 6.

[0025] In this embodiment, the threads on the left and right sides of the outer wall of the screw rod 10 are arranged relative to each other, so that when the screw rod 10 rotates, the left and right sides of its outer wall generate relative thread rotation forces, so that the two sliders 11 slide relatively at the same time under the limiting action of the limiting groove 14 and the limiting block 15.

[0026] In this embodiment, the limiting assembly includes a limiting groove 14 and a limiting block 15. The limiting groove 14 is opened at the bottom end of the inner cavity of the casing 4.

The exposure time of the sound 6 to the air is shortened, and the problem that the speaker of the multimedia display device in the prior art does not have a protective device and a large amount of dust is attached to the output end after being exposed to the air for a long time, which affects the normal use of the speaker, is solved. When the sound 6 needs to be used, the first motor 9 is started to make the first motor 9 drive the screw rod 10 to rotate, so that the threads on the left and right sides of the outer wall of the screw rod 10 generate relative thread rotation force, so that the two sliders 11 are limited between the limit groove 14 and the limit block 15. The second motor 16 is started to drive the screw 17 to rotate. Under the action of the threaded rotation force of the outer wall of the screw 17, when the screw 17 rotates, the movable cylinder 18 can push the fixed plate 2 and the display screen 3 to slide up and down along a straight line under the limiting action of the two telescopic rods 19, so as to realize the height adjustment of the fixed plate 2 and the display screen 3, which is convenient for the user to adjust the height of the display screen 3 according to the actual usage, thereby improving the flexibility of the device when in use.
