Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Please refer to Figures 1 to 7 , this embodiment provides a lifting multimedia display device, including a base 1 and a folding rod 2. The folding rod 2 is composed of a fixed rod 201 located below and fixed to the base 1 and a flipping rod 203 rotatably connected to the top of the fixed rod 201 through a hinge 202. A limiting assembly 204 for positioning the unfolded posture of the folding rod 2 is installed on the inner wall of the flipping rod 203. A first display screen 3 in an inclined shape is fixed on the outer wall of the lower end of the folding rod 2, and a lifting device 4 is installed on the folding rod 2. A second display screen 5 in a vertical shape is fixed on the lifting device 4;

[0024] Before folding, the second display screen 5 at the upper part of the lifting device 4 moves to Figure 1 and Figure 2At the position shown, then operate the limit component 204 to release the limit of the unfolded posture of the folding rod 2, and flip the flipping rod 203 so that the flipping rod 203 flips downward and folds. Finally, the hinge 202 is opened to the maximum angle, and the entire folding rod 2 is in the folded posture, and the display surface of the first display screen 3 faces the display surface of the second display screen 5;

[0025] Since the display height of the second display screen 5 can be raised and lowered, the diversity of the display effect is improved. By adding a first display screen 3, the two display screens can be displayed simultaneously, further improving the diversity of the display effect;

[0026] Particularly when the device is moved and transported, folding the folding rod 2 reduces the occupied space of the device, and the display surfaces of the first display screen 3 and the second display screen 5 face each other, and the display surfaces of the display screens are wrapped and not in an exposed state, so that the display surfaces of the display screens can be effectively protected from damage during the movement and transportation process;

[0027] The limit component 204 includes a connection block 2041 fixed to the top of the inner wall of the flipping rod 203. A limit rod 2042 is slidably installed in the middle of the connection block 2041 through a sliding hole. A pull ring 2043 is fixed to the top of the limit rod 2042. A spring 2044 is sleeved on the upper end of the limit rod 2042. One end of the spring 2044 is fixed to the top surface of the connection block 2041, and the other end of the spring 2044 is fixed to the bottom surface of the pull ring 2043. A stabilizing sleeve 2045 is fixed to the middle of the bottom surface of the inner wall of the flipping rod 203. The lower end of the limit rod 2042 is inserted into the inside of the stabilizing sleeve 2045. A through hole 2046 is opened in the middle of the bottom of the flipping rod 203. The through hole 2046 communicates with the stabilizing sleeve 2045. One end of the through hole 2046 close to the inner cavity of the flipping rod 203 is tapered. The limit rod 2042 is slidably inserted into the inside of the through hole 2046. A limit hole 2047 is opened in the middle of the top surface of the fixed rod 2047. The bottom of the limit rod 2042 is inserted into the inside of the limit hole 2047; a chamfer is provided on the upper edge of the inner wall of the limit hole 2047;

[0028] When operating the limit component 204 to unlock, by pulling the pull ring 2043, the limit rod 2042 is driven to slide upward, so that the lower end of the limit rod 2042 slides into the inside of the through hole 2046, and the lower end of the limit rod 2042 is separated from the limit hole 2047, thus completing the unlocking work. After that, the flipping rod 203 can be flipped;

[0029] When locking, the folding rod 2 is first flipped from the folded posture to the unfolded posture. During the flipping process, the pull ring 2043 is pulled to keep the limiting rod 2042 in the unlocked state. After the folded posture is reached, the lower end of the limiting rod 2042 faces the limiting hole 2047. The pull ring 2043 is released, and the limiting rod 2042 is pulled to slide under the action of the rebound force of the spring 2044 so that the bottom of the limiting rod 2042 passes through the through hole 2046 and is inserted into the limiting hole 2047. Then the folding rod 2 cannot be folded, and the limiting work is completed.

[0030] The lifting device 4 includes two racks 401 respectively fixed on the outer wall of the flip rod 203 and the outer wall of the fixed rod 201, and the ends of the two racks 401 are in contact with each other. A lifting member 402 is slidably installed on the outer wall of the folding rod 2, and the second display screen 5 is fixed on the lifting member 402. A rotating shaft 403 is rotatably connected to the inner wall of the lifting member 402 through a bearing. A gear 404 is fixed to the middle of the rotating shaft 403, and the gear 404 is meshed with the rack 401. A worm gear reduction motor 405 is fixed on the outer wall of the lifting member 402, and one end of the rotating shaft 403 is fixed to the output end of the worm gear reduction motor 405;

[0031] from Figure 7 It can be seen that the lifting member 402 can be lifted and lowered to stagger the hinge 202, and when the folding rod 2 is in the unfolded state, the ends of the two racks 401 are in contact with each other, the two racks 401 can be combined into a complete rack 401, and the gear 404 can be smoothly transmitted between the two racks 401;

[0032] Therefore, the use process of the entire lifting device 4 is as follows: when the height of the second display screen 5 needs to be adjusted, the worm gear reduction motor 405 is driven to work, driving the rotating shaft 403 to rotate, thereby driving the gear 404 to rotate, and the gear 404 moves the rack 401, thereby driving the lifting member 402 to slide up and down on the outer wall of the folding rod 2, thereby achieving the effect of adjusting the height of the second display screen 5.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
