Description

Technical Field

[0001] The utility model relates to the technical field of lifting brackets, and particularly relates to a display bracket with a wire winding function. Background Art

[0002] Various displays have been widely used in today's life. The existing displays are basically dominated by liquid crystal displays. A liquid crystal display is an approximately plate-shaped display, which cannot stand by itself and must be supported by a support device such as a support bracket to be used. Due to the reasons of the user's own height and usage habits, the support bracket of the display is often required to have a lifting function, so as to adjust the height of the display during actual use, so as to adjust to the user's own usage habits.

[0003] Chinese Utility Model CN201822005861.5 discloses a lifting bracket for a display, which can allow a user to randomly adjust the height and viewing angle of the display. However, the height of the column of the lifting bracket is fixed, and the display is lifted within a certain adjustment range of the lifting bracket, but the column of the lifting bracket will not lift together with the display, which affects the user experience and makes it inconvenient to transport the column of the lifting bracket during transportation, consuming too much packaging material. To solve the above problems, Publication No.: CN202220850166.2 discloses a liftable display bracket, including a base and a column. The base and the bottom of the column are connected. The top of the column is connected to a display connection bracket. The column includes a movable column part, and the top is connected to the display connection bracket; a fixed column part, which is connected to the base, and the movable column part is slidably connected within the fixed column part; the movable column part expands and contracts within the fixed column part for adjusting the height of the display connection bracket, and the movable column part and the display connection bracket move synchronously. According to the liftable display bracket of the present utility model, after the display connection bracket is connected to the display, by adjusting the height of the movable column part, the user can change the height of the display while also adjusting the height of the column, occupying less space and improving the user experience. And during transportation, the movable column part contracts into the fixed column part, making transportation more convenient and reducing packaging materials.

[0004] However, the above lifting bracket still has the following problems: 1. Its cables are mostly wound in a spiral section for cable storage, but the rear section of the cable cannot be stored, and the rear section of the cable will be folded, resulting in the contraction and jamming of the movable column part, and it is easy to cause the cable to be scratched, affecting the electrical connection and service life; 2.
