Two-seater: 1600mm (L) x 600mm (W) x 750mm (H) (Screen: 850mm + 350mm)
1. Folding Screen Lifting Mechanism: Utilizes a main unit and two auxiliary units with a six-toothed belt lifting transmission. Four lifting panels are balanced and stable in their rise and fall, with the lifting shell made of high-intensity flame-retardant nylon suitable for operation in environments ranging from -20°C to 120°C. The teeth are made of Φ12 steel rod, and the piping is galvanized. The overall structure is compact and robust.
2. The motor is a DC24V pure copper motor, capable of lifting and lowering 20,000 cycles (with a lifting frequency not exceeding 20%), noise level not exceeding 50dB, limit switch click life of at least 50,000 times, wire material withstands high temperature up to 120°C, all passing a 20kg tensile strength test, with a core of 0.75mm² copper wire, supporting current up to 10A (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 has an output 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 overload. 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 panels on the left, center, right, and front sides, with the top edge of the lifting panel 350mm higher than the side panels to block the view between neighboring examinees. When not in use, it can be lowered to serve as a standard computer classroom.
5. Desk body material requirements: The surface must be flat, with even color, sturdy, and free of harsh odors. Material thickness: 16mm. The material must comply with international or domestic environmental standards, meeting the E1 environmental grade. Formaldehyde emission is less than 1.5mg/L.
6. The left/middle/right swinging screen panels are made of 16mm thick boards, featuring flat surfaces, even coloration, durability, and no irritating odors. The boards must comply with either international or domestic environmental protection standards, meeting the E1 grade environmental standard.
7. The cutting edges of the table top panels are trimmed with aluminum alloy, using an interlocking method. All external surfaces of the aluminum materials must not expose screws or sharp metal parts. The sharp edges of the aluminum profiles should 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, with a fire-resistant 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, a bottom plate is included to accommodate the computer main unit, with two cable pass-through holes for ease of wiring.
11 Two modes of operation: Paper-based and computer-based exam mode (after the screen is raised, it serves as a deterrent to cheating), regular teaching state (screen lowered)
12. Each desk is equipped with an intelligent power switch for the computer tower (functions: power on/off/restart, two USB ports, one data port, and one charging port). The power on/off or USB insertion is directly operated on the desk, convenient and quick. For soundproof rooms, a dedicated professional earphone hanger can be provided.
