Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent lectern technology, specifically to a screen flipper and an intelligent lectern using the same. Background Technology
[0002] In the existing technology, the display screen tray on the smart lectern does not have cable guide holes or has only a single number of cable guide holes. When the connection point between the cable behind the display screen and the display screen is close to the edge of the display screen, even if the cable guide hole can pass through, it will cause excessive bending of the cable, which can easily damage the cable.
[0003] Therefore, this utility model is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a screen flipper and a smart podium using the same, so as to solve the technical problems existing in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a screen flipper, comprising: a housing, on which a support plate is rotatably mounted; a first mounting cavity and a second mounting cavity are respectively provided on both sides of the interior of the housing; the support plate is connected to the side wall of the first mounting cavity via a first connecting shaft, and the support plate is connected to the side wall of the second mounting cavity via a second connecting shaft; adjusting the rotation of the support plate so that the display screen horizontally mounted on the support plate is parallel to or at a certain angle to the top plate of the housing;
[0006] The pallet has a first wire hole on its main body surface and a second wire hole on its side wall surface.
[0007] In an optional embodiment, the first wire hole is located on the side of the tray body surface near the first connecting shaft.
[0008] In an optional embodiment, both the first wire guide hole and the second wire guide hole are elongated holes, and the length of the first wire guide hole is greater than the length of the second wire guide hole; the major axes of the first wire guide hole and the second wire guide hole are parallel, and the minor axes of the first wire guide hole and the second wire guide hole are located in the same plane.
[0009] In an optional embodiment, the display screen mounted on the tray moves with the tray, and the tilt angle of the display screen is 0°-85°.
[0010] In an optional embodiment, the housing is further provided with at least one USB interface, at least one HDMI interface, at least one Type-C interface, and at least one power socket.
[0011] In an optional embodiment, a driving component is provided in the first or second mounting cavity, the driving component being used to drive the tray to rotate.
[0012] In an optional embodiment, the housing is further provided with a power switch and adjustment buttons, the adjustment buttons including an up button, a down button and a stop button for adjusting the flip angle of the display screen.
[0013] In an optional embodiment, the tray is manually adjustable, and both the first connecting shaft and the second connecting shaft are damping shafts.
[0014] In an optional embodiment, a first limiting block and a second limiting block are provided on the side wall of the first mounting cavity or the second mounting cavity, and a swing rod is fixedly provided on the first connecting shaft or the second connecting shaft; the swing rod moves between the first limiting block and the second limiting block.
[0015] On the other hand, this invention also provides a smart lectern that uses the screen flipper described above.
[0016] The beneficial effects of this utility model are as follows:
[0017] The first and second cable guide holes on the screen flipper can accommodate different types of displays. The connection points of the cables behind the displays are sometimes close to the center of the display, and sometimes slightly off-center (these connection points are still within the coverage area of the first cable guide hole along its length). The first cable guide hole allows cables with connection points close to the center or slightly off-center to enter the smart lectern. When the cable is too stiff or the connection point is located on the side of the display or close to the side edge, the cable can pass through the second cable guide hole into the smart lectern. This extends the transition distance of the cable, thus preventing excessive bending of the cable from affecting the display adjustment and avoiding damage to the cable caused by excessive bending.

The worm gear 33 meshes with a worm wheel 35 disposed on a first rotating shaft 34, which is rotatably connected to the mounting frame 31. A first gear 36 is also disposed on the first rotating shaft 34, which meshes with a second gear 37 disposed on a second rotating shaft 39, which is rotatably connected to the mounting frame 31. A third gear 38 is also disposed on the second rotating shaft 39, which meshes with a fourth gear 311 disposed on a third rotating shaft 310, which is rotatably connected to the mounting frame 31. A fifth gear 312 is also provided on the third rotating shaft 310, which meshes with a sixth gear 314 provided on the fourth rotating shaft. The fourth rotating shaft is rotatably connected to the mounting bracket 31. A seventh gear 313 is also provided on the fourth rotating shaft, which meshes with an eighth gear 315 provided on the first connecting shaft 6.

[0031] Finally, a first wire-passing hole 22 is provided on the surface of the main body of the pallet 2, and a second wire-passing hole 23 is provided on the side wall surface of the pallet 2. The first wire-passing hole 22 is located on the side of the main body surface of the pallet near the first connecting shaft 6. 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 guide hole 22 and the second cable guide hole 23 on the screen flipper can adapt to different types of displays. The connection points of the connecting cables behind different types of displays are sometimes close to the center of the display, and sometimes slightly off-center (the connection points are still within the coverage area of the length direction of the first cable guide hole). The setting of the first cable guide hole 22 allows connecting cables with connection points close to the center or slightly off-center to enter the smart podium through the first cable guide 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 guide hole 23 to enter the smart podium. By extending the transition distance of the connecting cable, the excessive bending of the connecting cable can be avoided from affecting the adjustment of the display and the damage to the connecting cable caused by excessive bending can be avoided.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
