Description

Technical Field

[0001] This utility model relates to the technical field of display adjustment devices, specifically a display adjustment device. Background Technology

[0002] In current office, e-sports, and design scenarios, monitors, as core display devices, are seeing their usage demands evolve from single-screen to multi-screen setups. For example, financial professionals need to simultaneously view market data software and trading interfaces, while video editors need to split screens to process footage and preview effects; multi-screen setups have become an important way to improve work efficiency. However, existing monitor adjustment mechanisms still have many technical limitations, making it difficult to meet the needs of multi-screen collaborative use.

[0003] Some existing multi-screen stands use a fixed rod connection structure, which limits the adjustment of the relative positions between screens (such as left-right spacing and front-back distance) and cannot achieve independent angle fine-tuning of a single screen. For example, when a user needs to adjust the tilt angle of one of the screens, it often requires disassembly and reassembly, which is cumbersome and cannot quickly adapt to different usage scenarios (such as horizontal splicing display, vertical screen office, etc.).

[0004] Some existing multi-screen stands use a fixed rod connection structure, which limits the adjustment of the relative positions between screens (such as left-right spacing and front-back distance) and cannot achieve independent angle fine-tuning of individual screens. For example, when a user needs to adjust the tilt angle of one of the screens, it often requires disassembly and reassembly, which is cumbersome and cannot quickly adapt to different usage scenarios (such as horizontal splicing display, vertical screen office, etc.).

[0096] Work process:

[0097] I. Installation Phase (Initial Use)

[0098] Desktop clamping fixation

[0099] Place the monitor holder 1 on the edge of the target desktop (desktop thickness recommended 5-50mm), rotate the turntable 14 (grip the curved groove on the edge to apply force), align the red mark with the scale line on the bottom of the holder to determine the height of the clamping plate 13, until the clamping plate is tightly attached to the bottom of the desktop, the clamping force should be such that the device does not wobble (avoid over-tightening and damaging the desktop).

[0100] Display assembly

[0101] Align the VESA holes on the back of monitors a6 and b20 (19-32 inches, weight ≤8kg / unit) with the holes on the corresponding monitor mounting plate 7, and tighten them with the matching bolts through the holes (if the screens are not aligned, you can make a slight adjustment of ±5mm through the oblong holes on the mounting plate).

[0102] II. Multi-dimensional Adjustment Stage (Daily Use)

[0103] Dual-screen left and right spacing adjustment

[0104] Loosen the set screws on the side walls of adjusting cylinders a3 and b4, push the adjusting cylinders to slide along the axis of the main shaft 2 (sliding resistance ≤ 5N), adjust the left and right distance between the two displays, and after determining the position, tighten the set screws again to lock (positioning accuracy ≤ 0.5mm).

[0105] Single-screen angle fine-tuning

[0106] Directly push a single display (such as display a6) to drive the support arm 8 to rotate around the adjustment shaft 9 (rotation angle range -30° to +90°). The ball bearings 19 in the adjustment cylinder 10 rotate smoothly with the adjustment shaft. If the rotation resistance is too high, the bolts 17 between the shaft cylinders a101 and b102 can be loosened to fine-tune the gap. After adjustment, they can be tightened again (operating torque ≤3N・m).

[0107] Clamping tightness adjustment

[0108] If the thickness of the tabletop changes or the device becomes loose, rotate the turntable 14 again and observe the rise and fall of the clamping plate 13 through the scale line until the tabletop is clamped again to ensure the device is stable.

[0109] III. Maintenance and Inspection Phase (Regular Operations)

[0110] Routine inspection

[0111] Inspect all bolted connections weekly (such as the main support arm and the adjusting cylinder, and the shaft cylinder connecting plate). If any loosening is found, tighten them to the standard torque (25 N·m for M10 bolts, 8-10 N·m for M5 bolts).

[0112] Regular maintenance (every 3 months)

[0113] Cleaning: Wipe the mating surfaces of spindle 2 and adjusting cylinder with a dry cloth to remove dust;

[0114] Lubrication: Open the transparent dust cap of the rotating cavity 18 and inject 0.5g of lithium-based grease per rotating cavity into the oil injection hole;

[0115] Functional test: Complete one full adjustment cycle (spacing + angle + clamping) to confirm there is no jamming or looseness.

[0116] Long-term idle status (more than 6 months)

[0117] Slide the adjusting cylinder to the middle position of the main shaft, adjust the support arm to be horizontal, and cover it with a dust cover to prevent dust accumulation.
