Description

Technical Field

[0001] The utility model relates to the technical field of display brackets, in particular to a height-adjustable display bracket. Background Art

[0002] With the development of the times, the application of computers in life is becoming more and more common, and monitors, as an important component of computers, are also attracting more and more attention, and the requirements for monitors are also getting higher and higher.

[0003] However, people tend to only focus on the monitor screen and often ignore the improvement of the monitor support base, resulting in the support base only playing a supporting role, but not achieving the ideal effect in terms of adjustment. If the monitor cannot adjust the display screen direction as desired, it often has an adverse effect on the user's sitting posture and may even cause symptoms. In addition, since the monitor itself is large in size, even if a smaller base can be designed, the space occupied by the monitor will still be relatively large, making the desktop where the monitor is placed appear very crowded. Therefore, a base that only plays a supporting role is increasingly unable to meet people's needs.

[0004] In order to overcome the above defects, some height-adjustable monitor stands have appeared on the market. The height adjustment of common monitor stands is achieved through a four-bar linkage mechanism of the arm joint under the balancing action of a balancing spring or a cylinder rod. Such a structure is relatively complex and costly.

[0005] Therefore, it is urgent to provide a height-adjustable display stand to overcome the above-mentioned defects. Utility Model Content
