Description

TECHNICAL FIELD

[0001] The utility model relates to display support field, specifically, relates to a liquid crystal display support structure convenient for extension. BACKGROUND

[0002] The liquid crystal display support structure is mainly the component and device for supporting the liquid crystal display body and ensuring its stability. The design of these support structures directly affects the stability, adjustment function and appearance of the display. The liquid crystal display support structure usually includes a base, a support, a cantilever and a wall-mounted support, and the liquid crystal display support structure not only affects the stability of the display, but also directly affects the use experience. Selecting a suitable support structure can improve work efficiency and comfort.

[0003] However, most of the current liquid crystal display support structures have the following problems:

[0004] The existing liquid crystal display support structure is mostly supported by installing a support base on the counter or desktop, but the size of the existing support base is mostly fixed. If the liquid crystal display is large, it is difficult to support the support base stably, and a larger support base is needed to support it, which is inconvenient to adjust and adapt the size of the support base. At the same time, when the existing support base is placed on the counter or desktop, the stability of the device is mostly supported by the weight of the liquid crystal display. If it is hit or shaken by external force, it is easy to cause the support base and the liquid crystal display to tilt or fall, and it is not convenient to adsorb and fix the support base on the counter or desktop.

[0005] Therefore, we improve it and propose a liquid crystal display support structure convenient for extension. UTILITY MODEL CONTENTS
