DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 As shown, a portable display screen with a supporting structure comprises a main body box 1 and a display screen main body 2. A bearing passes through the center position of the top of the main body box 1 to connect to a rotating sleeve 3. A worm gear 4 is arranged at the bottom of the rotating sleeve 3. A rotating frame 5 is fixedly connected to the top of the rotating sleeve 3. A rotating shaft 6 is sleeved in the rotating sleeve 3 and the rotating shaft 6 is connected to the rotating frame 5 by a bearing. A bevel gear 7 is arranged on the top of the rotating shaft 6, and a worm gear 2 8 is arranged at the bottom of the rotating shaft 6. Two groups of worms 9 pass through the main body box 1 and are rotatably connected with the bearing. The two groups of worms 9 are respectively meshed with the worm gear 4 and the worm gear 2 8. A lateral bearing in the rotating frame 5 is connected to a rotating shaft 2 10. A bevel gear 2 11 is arranged on the rotating shaft 10, and the bevel gear 2 11 meshes with the bevel gear 7. A display screen main body 2 is arranged on the rotating shaft 10. A fixing block 12 is fixed to the rotating shaft 10, a connecting rod 13 is fixed to the fixing block 12, and an end of the connecting rod 13 is fixed to the display screen main body 2.

[0021] like Figure 1 , 3 As shown, the ends of the two groups of worm gears 9 are fixedly connected to knobs 14, the side wall of the main box 1 is fixedly connected to a handle 15, the handle 15 is provided with a soft silicone layer 17, and also includes a telescopic rod 16, the telescopic rod 16 is fixedly connected to the bottom wall of the main box 1 and is evenly arranged in four groups for easy telescopic installation and storage.

[0022] During specific use, the rotating sleeve 3 is driven to rotate by rotating the worm 9 meshing with the worm gear 4, which in turn drives the rotating frame 5 to rotate and then drives the display screen body 2 to rotate. The worm 9 meshing with the worm gear 8 drives the rotating shaft 6 to rotate and then drives the bevel gear 7 to rotate. At this time, the bevel gear 7 meshes with the bevel gear 11 and rotates to drive the fixed block 12 to rotate, and the fixed block drives the display screen body 2 to rotate. The telescopic rod 16 can be provided to facilitate support installation and storage.
