[0023] Example 1
[0024] Please see the appendix Figure 1-3 The purpose of this embodiment is to provide a manual screen flipper, including: a housing 1, a tray 2 rotatably mounted on the housing 1, and a first mounting cavity 11 and a second mounting cavity 12 respectively provided on the inner two sides of the housing 1; the tray 2 is connected to the side wall of the first mounting cavity 11 through a first damping shaft 4, and the tray 2 is connected to the side wall of the second mounting cavity 12 through a second damping shaft 3; the tray 2 is manually adjusted to rotate so that the display screen mounted horizontally on the tray 2 is parallel to or at a certain angle to the top plate 13 of the housing 1, that is, the display screen mounted on the tray 2 moves with the tray 2, and the flip angle of the display screen is 0°-85°.
[0025] Furthermore, the housing 1 is also provided with at least one USB port, at least one HDMI port, at least one Type-C port and at least one power socket for media input or output.
[0026] In this embodiment, at least two connecting through holes 21 are provided on the surface of the tray body of the tray 2. The at least two connecting through holes 21 are used to install the display screen, making the installation and removal of the display screen more convenient.
[0027] Specifically, a first wire-passing hole 22 is provided on the surface of the main body of the pallet 2, and the first wire-passing hole 22 is located on the side of the main body of the pallet near the first damping shaft 4. A second wire-passing hole 23 is provided on the side wall surface of the pallet 2. Both the first wire-passing hole 22 and the second wire-passing hole 23 are elongated holes, and the length of the first wire-passing hole 22 is greater than the length of the second wire-passing hole 23. The major axes of the first wire-passing hole 22 and the second wire-passing hole 23 are parallel, and the minor axes of the first wire-passing hole 22 and the second wire-passing hole 23 are located in the same plane. The first cable pass hole 22 and the second cable pass hole 23 can accommodate different types of displays. The connection points between the connecting cables behind the display and the display are sometimes close to the center of the display, and sometimes slightly off-center (the connection point is still within the coverage area of the length direction of the first cable pass hole). The first cable pass hole 22 allows connecting cables with connection points close to the center or slightly off-center to enter the smart lectern through the first cable pass hole 22. When the connecting cable is too stiff or the connection point between the connecting cable and the display is located on the side of the display or close to the side edge of the display, the connecting cable can pass through the second cable pass hole 23 to enter the smart lectern, extending the transition distance of the connecting cable and thus avoiding excessive bending of the connecting cable that would affect the adjustment of the display.
[0028] In addition, a first limiting block 52 and a second limiting block 53 are provided on the side wall of the first mounting cavity 11, and a swing rod 51 is fixedly provided on the first damping shaft 4; the swing rod 51 moves between the first limiting block 52 and the second limiting block 53.
[0029] This screen flipper is manually adjustable. The display screen is mounted on a tray, and the tray is connected to the housing via a damping hinge. It can hover the display screen at any position between 0-85°. It has a simple structure, low manufacturing cost, and is easy to use.
