One display screen bracket 2-1 faces the required direction; two display screen brackets 2-1 can be used in shopping malls and other places where publicity content is required, and the present invention is placed in the center of the two-way flow of people, so that the flow of people on both sides can be After watching the content played on the screen, when the user needs a large screen to explain the content, etc., the two display brackets 2-1 can be spliced into a large screen, which is easy to explain and the large screen is convenient for the audience to watch the content on the screen. ;When connecting seat 3 is used, motor II3-6 is controlled by wires and power supply, motor II3-6 drives disc 3-7 to rotate, disc 3-7 drives eccentric shaft 3-8 to make a circle around the center of disc 3-7 Movement, the eccentric shaft 3-8 drives the connecting rod 3-5 to move, the connecting rod 3-5 drives the support arm 3-4 to move, and the support arm 3-4 drives the support shaft 3-3 to make a certain angle so that the support shafts 3-3 can drive the pivot frame 1 and the rotating screen frame 2 to rotate; when rotating the screen frame 2 to display the content, swinging left and right can increase the display angle, making it easier for pedestrians to notice the rotating screen frame 2, and when the pedestrian moves, the swing of the rotating screen frame 2 can make the angle of the screen follow the pedestrian to move a certain distance, making it easier for pedestrians to observe the content in the rotating screen frame 2; The hinged connection between the turntable 3-9 and the lower turntable 4-4 enables the lower turntable 4-4 and the upper turntable 3-9 to rotate relative to each other. When installing the latch 4-6, insert the latch 4-6 into the outside of the latch frame 4-5 first. Then install the compression spring 4-7 on the pin 4-6, then connect the washer 4-8 to the pin 4-6 by screwing, and finally insert the pin 4-6 into the pin holder In the hole of the vertical support rod on the inner side of 4-5; when the angle of the rotating screen frame 2 of the present invention is not convenient for the viewer to watch, pull the pin 4-6 outward, so that the inner end of the pin 4-6 slides out of the jack 3-10, after adjusting the relative angle of the lower turntable 4-4 and the upper turntable 3-9 to a suitable angle, release the pin 4-6, and insert the inner end of the pin 4-6 into the corresponding hole 3-10 to This fixes the relative angle between the lower turntable 4-4 and the upper turntable 3-9; when the height of the rotating screen frame 2 needs to be adjusted to the required height, the drive motor III4-10 rotates to make the lifting gear 4-15 rotate, and the lifting gear When 4-15 rotates, it can drive the lifting plate 4-3 to slide up and down in the outer bin body 4-1 through the meshing transmission with the rack 4-9, and the four guide rods 4-17 can limit the position of the lifting plate 4-3. The top of the four guide rods 4-17 is provided with a disc whose outer diameter is larger than the rod body of the four guide rods 4-17, so that the lifting plate 4-3 will not be deflected. 3. It will not exceed the outer compartment body 4-1. Due to the self-locking characteristics of the worm gear and worm, when the motor III4-10 does not rotate, the lifting plate 4-3 will rise and fall and maintain the height when the motor III4-10 stops. When the present invention needs to be used, rotate the two display screen brackets 2-1 so that the inner edges of the display screen brackets 2-1 on both sides are respectively clamped on the gear rods 1-4 on both sides. At this time, the two display screen brackets 2 -1 The expansion distance is the shortest, and then the lifting plate 4-3 is lowered to the bottom end, so that the central frame 1, the rotating screen frame 2 and the connecting seat 3 are all lowered into the outer warehouse body 4-1, so that the central alignment can be realized. The protection of the frame 1, the rotating screen frame 2 and the connecting seat 3; after the shrinkage is completed, the cubic shape of the outer warehouse body 4-1 is more convenient for the movement and transportation of the present invention, so that the present invention can be used in more scenes.

Of course, the above description does not limit the invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essential scope of the present invention also belong to the present invention. protected range.
