Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and more specifically, to a portable liquid crystal display. Background Technology

[0002] LCD screens are a type of flat panel display used for computer screens. They are small and portable, and can be moved simply by installing wheels. However, existing portable LCD screens still have some drawbacks that affect daily use.

[0003] The primary problem is that existing portable LCD screens cannot be adjusted in height. Users of different heights have vastly different needs for the optimal viewing height. A fixed screen height may force some people to tilt their heads back, down, or sideways to view the screen, making it impossible to achieve a comfortable eye-level viewing angle. Prolonged viewing of a screen that is too low can lead to excessive forward flexion of the cervical spine, increasing pressure on the intervertebral discs and potentially causing cervical spondylosis and neck muscle strain. Conversely, if the screen is too high, tilting the head back may cause cervical spine extension injuries and shoulder pain. Furthermore, to adapt to the screen height, users may unconsciously adjust their posture, increasing pressure on the lumbar spine.

[0004] More importantly, the existing mobile LCD screen shelves cannot be easily folded for storage. The inability to fold shelves means that the equipment occupies fixed vertical space when not in use, which greatly reduces storage flexibility. In scenarios with limited space, such as home studies and small offices, non-folding shelves will continuously occupy valuable space on the floor or storage shelves, which may conflict with the placement of other furniture and equipment, or even lead to a crowded and cluttered space. When passing through corridors or elevator shafts, the fixed width or height of non-folding shelves may exceed the passage restrictions, causing the equipment to be unable to pass smoothly, forcing a change of route or abandonment of the use of the scenario, thus limiting the scope of application of the equipment.

[0005] Crucially, existing portable LCD screens lack expansion devices. Expansion devices provide storage space for the screen. When presenting on the screen, speakers need to constantly reach for the microphone to adjust the volume or pick up a pen to mark key points. Without nearby storage devices, they may need to frequently turn around to the table to retrieve these items or bend down to find temporarily placed tools on the ground, leading to interruptions in their train of thought, a slow pace, and affecting the audience's concentration. Microphones, page turners, styluses, and other accessories are small and easily confused. In mobile scenarios, without fixed storage devices, they are easily left behind in the venue, transport vehicles, or storage corners. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a mobile liquid crystal display screen, which has the following advantages:

[0018] 1. A complete display screen lifting frame is formed by the close cooperation between the turbine, worm gear, rack, lifting column, housing and moving base. The worm gear drives the rack to move, which in turn drives the lifting column to move the display screen up and down. By adjusting the height of the frame, the screen can be precisely positioned at a comfortable viewing angle of eye level or slightly lowered, avoiding uncomfortable postures such as looking up or bending over caused by a fixed height. When the display screen needs to be used with other equipment, the lifting frame can be quickly adapted to raise or lower the screen, leaving more reasonable operating space and improving collaboration efficiency.

[0019] 2. Through the tight cooperation between the connecting column, connecting rod, mounting base, support rod, support base, and mounting block, a complete detachable mounting rack is formed. The display screen can be fixed to the connecting column via the connecting rod by fixing the mounting base and mounting block. The support rod supports the display screen to make it more stable. At the same time, the connecting rod allows the display screen to be adjusted in angle. The two connecting rods can be detached from the connecting column and the display screen, reducing the size of the rack and reducing the space occupied during transportation. In addition, the rack can be easily stuffed into the storage cabinet, under the desk, or in the corner gap, avoiding the long-term occupation of the core space of the floor or storage shelf like non-folding racks.

[0020] 3. Through the tight cooperation between the track, rotating head, stud, washer, and shelf, a complete expansion assembly is formed. Objects such as remote controls, pens, and teaching aids used with the display screen can be placed on the shelf. Users can easily take out a microphone from the expansion device to adjust the volume, or pick up a pen to mark important points on the screen without having to turn around and walk to a distant table or bend down to find temporarily placed tools on the ground. By rotating the rotating head to adjust the length of the stud, the position of the shelf on the track can be changed, making it more convenient to retrieve tools. The expansion device provides fixed storage space for small peripherals such as microphones and pens, effectively preventing the loss caused by random placement. Attached Figure Description
