Description

Technical Field

[0001] The utility model belongs to the technical field of display brackets, and specifically relates to an adjustable display bracket. Background Technique

[0002] A display is a display instrument that can achieve human-computer interaction. In order to improve the user experience, a support frame is usually used to place the display upright on the desktop so that users can sit in front of the table and interact with the computer. To further ensure the comfort of users, the support frame generally has the function of lifting and lowering the height of the display so that users of different heights can look directly at the display in front of the table.

[0003] The Chinese patent document "CN211176017U, a lifting bracket suitable for a display" includes a bracket body and a rotating seat. A lifting slide rail is installed in the bracket body, and a lifting slide seat is slidably connected to the lifting slide rail to realize the lifting function of the display. One end of the rotating seat is fixedly connected to the end of the support arm away from the lifting slide seat, and the other end of the rotating seat is movably connected to a hinge assembly for adjusting the pitching angle of the mounting plate. At the same time, the rotating seat can also be used to enable the hinge assembly to rotate a preset angle in the horizontal direction, facilitating the user to adjust the horizontal angle of the display.

[0004] However, when this bracket rotates in the pitching perspective, there is no clear rotation angle limit. Although this design provides greater flexibility, in actual use, the pitching adjustment without an angle limit may cause the display to tilt excessively, which in turn causes the center of gravity of the display to shift, increasing the risk of the display tipping over.
