Single-User Elevating Computer Desk

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

1. Screen Divider Lift Mechanism: Utilizes a main motor and two auxiliary motors with a six-toothed belt lifting transmission. The four lifting panels are evenly and smoothly raised and lowered, with the lifting housing 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, with the overall structure being compact and robust.

2. The motor is a DC24V pure copper motor, capable of 20,000 lifts/drops (frequency not exceeding 20%), with noise no more than 50db, limit switch click life of at least 50,000 times, high-temperature wire material rated for 120℃, all passing a 20kg tensile test, with a wire core of 0.75mm² copper wire, supporting up to 10A current (with a normal operating current of 2A for the motor).

3. The control box can receive 433MHz wireless signals up to 100 meters away and has a maximum output power of 120W (5A). It can automatically protect the product and emit a double 1 beep alarm in case of short circuit or overloading. The control box comes with up/down buttons for emergency or maintenance use. It is equipped with a group remote control (divisible into 9 channels for control) for flexible grouping control.

4. The lifting screen features lifting plates on the left, center, right, and front sides. 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. Desk body material requirements: The surface must be flat, color even, sturdy, odor-free, with a thickness of 16mm. The material must comply with international or domestic environmental protection standards, meeting the E1 grade environmental standard. Formaldehyde emission level below 1.5mg/L.

6. The left/middle/right panels of the adjustable screen are made of 16mm thick plates, featuring flat surfaces, even coloration, durability, and no harsh odors. The materials must comply with international or domestic environmental protection standards and meet the E1 environmental grade.

7. The table body panel cutting edges are bordered with aluminum alloy, using an interlocking method. All external surfaces of the aluminum materials must not have exposed screws or sharp metal parts. The sharp edges of the aluminum profile 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 overall fixed screws are designed to be concealed.

9. The lift chair desk is made of E1 grade 25mm particleboard, featuring a fire-retardant panel surface 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, there's a bottom plate for the computer main unit, with two routing holes for easy cable management.

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

12. Each desk is equipped with an intelligent power switch for the computer host (features: turn on/off/restart the computer, two USB ports, one data interface, and one charging port). Power on/off or insert USB ports can be directly operated on the desk for convenience and speed; for soundproof rooms, a dedicated earphone hanger can be provided.
