DETAILED DESCRIPTION

[0016] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0017] Referring to the accompanying drawings, a liftable display board includes a base plate 1, a display screen 6 and rollers 11, the rollers 11 are movably arranged on both sides of the base plate 1, the display screen 6 is arranged on the base plate 1, cylinders 2 are fixedly installed on both sides of the base plate 1, the output end of the cylinder 2 is connected to a piston rod 3, the top ends of the two piston rods 3 are connected to the lifting plate 4, the lifting plate 4 is in a "U" shape, the display screen 6 is arranged on the lifting plate 4, a lifting frame 10 is sleeved on the peripheral side of the base plate 1, an L-shaped plate 8 is connected to the upper part of the inner wall of the lifting frame 10, an opening is opened on the base plate 1, and the L-shaped plate 8 is movably inserted into the opening on the base plate 1, when moving, the lifting frame 10 can be moved upward on the base plate 1, and the lifting frame 10 is used to cover the outer side of the display screen 6, and the display screen 6 is protected during the movement, when the device is in use, the display screen 6 displays comparative data, the lifting frame 10 can be moved up and down on the base plate 1, and the lifting plate 4 is moved down and close to it. After it reaches the ground, the device can be stopped. Two fixed plates 12 are arranged on the bottom plate 1 near the L-shaped plate 8. An axle rod is connected between the two fixed plates 12. A gear 13 is movably mounted on the axle rod between the two fixed plates 12. The L-shaped plate 8 is provided with teeth meshing with the gear 13. The gear 13 is rotated on the axle rod between the two fixed plates 12, and the L-shaped plate 8 is driven up and down by the gear 13 to realize the up and down movement of the lifting frame 10 on the bottom plate 1. A vertical plate 9 is connected to the middle part below the lifting plate 4. The vertical plate 9 is provided with teeth on one side close to the gear 13. An opening is provided on the bottom plate 1 for the vertical plate 9 to move through. Under the action of the cylinder 2 and the piston rod 3, the display screen 6 on the lifting plate 4 is driven to move up and down, and the vertical plate 9 is driven to move up and down at the same time. The gear 13 is driven to rotate by the teeth on the vertical plate 9, and then the up and down movement function of the lifting frame 10 is automatically realized on the bottom plate 1.

[0018] A rotating rod 7 is rotatably passed through the middle of the lifting plate 4, and the top of the rotating rod 7 is connected to the rotating plate 5. The display screen 6 is fixedly inserted into the groove provided on the rotating plate 5. With the rotating rod 7 as the axis, when the rotating plate 5 is rotated on the lifting plate 4, the display screen 6 can be rotated. According to the actual needs, the display angle of the display screen 6 can be adjusted, which is more flexible to use. The rotating plate 5 is movably provided with a clamping rod 14 on both sides, and a clamping groove 15 is provided on both sides of the lifting plate 4. The clamping rod 14 is inserted into the clamping groove 15. After the rotating plate 5 is completely rotated into the lifting plate 4, the clamping rod 14 is inserted into the clamping groove 15, and the rotating plate 5 and the display screen 6 are fixed on the lifting plate 4 to avoid collision between the display screen 6 and the lifting frame 10 during the movement. The problem of damage is caused by the fact that slide grooves 17 are provided on both sides of the rotating plate 5, and a slider 16 is slidably arranged in the slide groove 17. The cross-sections of the slider 16 and the slide groove 17 are both in a "T" shape. One end of the clamping rod 14 is connected to the slider 16, and a spring 18 is connected between the slider 16 and the lower groove wall of the slide groove 17. When the rotating plate 5 is rotated on the lifting plate 4, the clamping rod 14 is driven to move into the clamping groove 15. The clamping rod 14 first squeezes the groove wall of the clamping groove 15, driving the slider 16 to slide downward in the slide groove 17, and the squeezing spring 18 is compressed. When the rotating plate 5 is completely rotated into the lifting plate 4, under the elastic force of the spring 18, the clamping rod 14 is pushed into the clamping groove 15 through the slider 16 and clamped, so that the rotating plate 5 and the display screen 6 are fixed more firmly on the lifting plate 4.

[0019] When moving the device, start the cylinder 2 and the piston rod 3 to drive the display screen 6 on the lifting plate 4 to move downward, the vertical plate 9 drives the gear 13 to rotate, and the lifting frame 10 is driven to move upward through the L-shaped plate 8. After the lifting frame 10 covers the peripheral side of the display screen 6, it can protect the display screen 6 during the movement of the device. When using the device, the cylinder 2 and the piston rod 3 push the display screen 6 on the lifting plate 4 to move upward to drive the lifting frame 10 to move downward on the bottom plate 1. When the display screen 6 moves to the highest position, the bottom of the lifting frame 10 is close to the ground, which stops the device. The display screen 6 is used to display comparative data. If necessary, the card rod 14 can be pulled out of the card slot 15, and the rotating plate 5 can be rotated on the lifting plate 4 to flexibly adjust the display angle of the display screen 6. The operation is simple and easy to use.

[0020] The utility model has a lifting frame on the peripheral side of the bottom plate, and the L-shaped plate on the inner wall of the lifting frame is inserted into the opening provided on the bottom plate. When the device is moved, the L-shaped plate is moved upward in the opening on the bottom plate to drive the lifting frame to move upward to the peripheral side of the display screen, and the display screen is protected during movement. When the device is working, the L-shaped plate can be moved up and down on the bottom plate to drive the lifting frame to move down and press against the ground, which stops the device. The lifting plate is connected to the top of the piston rod at the output end of the cylinder, and a vertical plate is connected to the middle of the lifting plate. The vertical plate and the L-shaped plate are connected by gear meshing. Under the action of the cylinder and the piston rod, the lifting frame can be automatically driven to move up and down while the display screen on the lifting plate is pushed up and down, and the operation is more convenient. The display screen can be rotated at multiple angles to display comparative data.
