Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rotary liquid crystal display, more particularly, it relates to a rotary liquid crystal display. BACKGROUND

[0002] With the rapid development of information office and intelligent home, liquid crystal display has become an important equipment indispensable for modern office and home entertainment, however, it is found that the current product still has key technical problems to be solved in display angle adjustment, installation and maintenance convenience and structural stability.

[0003] In the prior art, the angle adjustment structure of liquid crystal display generally adopts fixed support or simple single-axis rotation design, which exposes significant adjustment limitations in practical application, specifically, the traditional support usually only supports limited pitch angle adjustment (generally -5° to +15°), and cannot realize horizontal rotation, in actual use, users need to frequently adjust the display angle to adapt to different use scenarios, such as video conference, document editing, multimedia playback, etc., however, the existing fixed support cannot flexibly adapt to various use scenarios, which becomes the primary obstacle restricting the use experience of liquid crystal display.

[0004] Secondly, for the mounting structure between the liquid crystal display screen body and the connecting frame, the prior art generally adopts a complex fastening system, and at least multiple professional tools are needed to complete a standard installation or disassembly operation, including various types of hexagonal wrench, cross screwdriver, open-end wrench and special nut fastener, etc., and there is a risk of incorrect installation, which increases the average maintenance cost, in addition, small faults are easily evolved into big problems due to untimely equipment maintenance, further increasing the maintenance cost, and prolonging the equipment downtime, affecting normal office activities.

[0005] In addition, in view of the problem of complicated installation and maintenance, some improved products have appeared on the market to attempt to realize convenient disassembly and assembly between the liquid crystal display body and the connecting frame. However, in-depth stability tests have revealed that such quick connection structures have significant safety hazards. Such structures usually adopt a simplified fixing mechanism. Although these designs exhibit sufficient support force in static conditions, they exhibit obvious instability in dynamic working environments. Specifically, when the desktop vibrates (such as personnel walking, equipment running, etc.) and the liquid crystal display body rotates in angle, the system will produce obvious vibration and impact. These vibrations will be directly transmitted to the connecting structure. The stability of the simplified connecting structure significantly decreases after long-term use. Some quick connection points show signs of loosening. More seriously, some samples even completely fall off under the action of long-term vibration. This not only causes serious damage to the equipment, but also causes potential personal safety hazards. This technical defect, in which the simple structure is easily affected by vibration and causes the fixing structure to loosen or even fall off, has become a key bottleneck restricting the wide application of quick connection technology, which has brought significant adverse effects on the safe operation of the equipment and the personal safety of the user.
