[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] As shown in Figures 1-6 The present application provides a technical solution: a rotatable display screen, comprising: a display screen body 1;

[0038] As shown in Figures 2-3 The rotating assembly 2 is arranged on one side of the display screen body 1, and the rotating assembly 2 comprises a support 21 fixed on one side of the display screen body 1. The bottom of the support 21 is provided with a base 22. A horizontal sliding block 23 is fixedly connected to one side of the support 21 close to the base 22. The horizontal sliding block 23 is rotationally connected to the base 22. An upper gear 24 is fixedly connected to one side of the horizontal sliding block 23 away from the support 21. A driving wheel 26 is rotationally connected to one side of the base 22 close to the upper gear 24. The driving wheel 26 is in transmission connection with the upper gear 24. The top of the driving wheel 26 is provided with a knob 25.

[0039] As shown in Figures 2-4As shown, the transmission assembly 3 is located inside the rotating assembly 2 and is used to increase the rotation direction of the display screen body 1. The transmission assembly 3 includes a transmission shaft 31 disposed inside the bracket 21. The transmission shaft 31 is movably connected to the horizontal slider 23 and the upper gear 24. A vertical slider 33 is rotatably connected to one end of the bracket 21 near the top of the transmission shaft 31. A bevel gear 34 is fixedly connected to one end of the vertical slider 33 and the other end of the transmission shaft 31 that are close to each other. The other end of the transmission shaft 31 away from the bevel gear 34 is fixedly connected to... A lower gear 32 is connected. A common rotating shaft is installed on the drive wheel 26, causing the drive wheel 26 to rotate inside the base 22. A knob 25 is fitted onto the rotating shaft of the drive wheel 26. Rotating the knob 25 causes the drive wheel 26 to rotate. Since the upper gear 24 meshes with the drive wheel 26, the drive wheel 26, through the upper gear 24, drives the horizontal slider 23 to rotate on the base 22. The horizontal slider 23 causes the bracket 21 and the display screen body 1 to adjust their angles. During the rotation of the display screen body 1 and the bracket 21, one... The direct-drive mechanism ensures that the bracket 21 and the display screen body 1 rotate via mechanical transmission. This solves the problem that when manually rotating the display screen, it is difficult for users to accurately control the magnitude and direction of force, which can easily lead to uneven force or excessive force. This avoids scratches and cracks on the screen surface during rotation, thus improving screen protection. When the display screen body 1 needs to rotate vertically, the drive shaft 31 is pushed upward. The drive shaft 31 drives two sets of bevel gears 34 to mesh with each other. At the same time, it drives the lower gear 32 to move upward. The lower gear 32 pushes the upper gear 24 to separate from the drive wheel 26 and engages with the drive wheel 26. Then, the knob 25 is turned, and the drive wheel 26 drives the drive shaft 31 to rotate via the lower gear 32. The drive shaft 31 applies force to the vertical slider 33 via the bevel gears 34, causing the vertical slider 33 to drive the display screen body 1 to rotate along its central axis on the bracket 21. This achieves vertical rotation of the display screen body 1 while maintaining the rotation of the bracket 21 via mechanical transmission, which is beneficial for improving screen protection.
