LCD screen riser

Two-seater: 1600mm (L) x 600mm (W) x 750mm (H) (Screen divider: 850mm + 350mm)

1. Screen Divider Lifting Mechanism: Equipped with a main engine and two auxiliary engines, using a six-toothed belt lifting transmission method. The four lifting plates ensure balanced and smooth lifting. The lifting housing is made of high-strength flame-retardant nylon material, suitable for operation in environments ranging from -20°C to 120°C. The teeth are Φ12 steel, and the pipes are galvanized. The overall structure is compact and sturdy.

2. The motor is a DC24V pure copper motor, capable of lifting and lowering up to 20,000 cycles (frequency not exceeding 20%), with noise below 50dB, a limit switch lifespan of at least 50,000 clicks, wire material that withstands high temperatures up to 120°C, and has passed a 20kg tensile test. The wire core is 0.75mm² copper wire, supporting up to 10A current (with the motor's normal operating current at 2A).

3. The control box can receive 433MHz wireless signals within a range of 100 meters and can output a power of up to 120W (5A). The product can automatically protect itself and emit a double-beep alarm sound in case of abnormal conditions such as short-circuit or overloading. The control box is equipped with up/down buttons for emergency or maintenance use. It comes with a grouped remote control (divisible into 9 groups of channels) for flexible grouping control.

4. The lift screen features lifting gates on the left, center, right, and front edges. The top edge of the lifting plate is 350mm higher than the side panels, designed to block the view of neighboring examinees. When lowered, it can be used as a standard computer classroom.

5. Tabletop material requirements: flat surface, even color, sturdy, free of irritating odors. Material thickness: 16mm. The material must meet international or domestic environmental standards, and comply with E1 environmental grade. Formaldehyde emission less than 1.5mg/L.

6. The left/middle/right panels of the adjustable screen are made of 16mm thick plates, with flat surfaces, even color, sturdy, and free of irritant odors. The materials must comply with international or domestic environmental protection standards, meeting E1 environmental grade.

7. The cutting surfaces of the table tops are edged with aluminum alloy, using an insertion method. All external surfaces of the aluminum cannot have exposed screws or sharp metal parts. The sharp edges of the aluminum profiles on the cutting surfaces must not exceed or protrude beyond the table's outer surface to ensure no cuts or injuries during use.

8. To ensure the overall stability and aesthetics of the lifting seat, the fixed screws are designed to be concealed.

9. The lift chair desk is made of 25mm thick E1 grade particleboard, with a fire-resistant panel surface on the top and a ya mouth edge design, with formaldehyde emissions below 1.5mg/L.

10. The door panel features two rows of ventilation holes, decorated with stainless steel mesh covers. Inside, a bottom plate is included to accommodate the computer main unit, and it features two cable pass-through holes for easy wiring.

11 Two modes of operation: paper-based and computer-based exam mode (the screen rises to prevent cheating), regular teaching mode (the screen is lowered)

12. Each desk position is equipped with an intelligent power switch for the computer tower (features: power on/off/restart, two USB ports, one data port, one charging port). The power on/off or USB insertion is directly operated on the desk, convenient and quick. For soundproof rooms, a professional earphone hanger can be provided.
