The four hoisting panels are balanced and stable in lifting, 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 pipe material is galvanized pipe. The overall structure is compact and robust.
2. The motor is a DC24V pure copper motor, capable of lifting and lowering 20,000 cycles (frequency not exceeding 20%), with noise level not over 50dB, limit switch click life of at least 50,000 times, wire material is 120°C high-temperature resistant wire, all passing a 20kg tensile test, with wire core of 0.75 square copper wire, supporting up to 10A current (normal operating current of the motor is 2A).
3. The control box can receive 433MHz wireless signals up to 100 meters away and can output a power of up to 120W (5A). The product can automatically protect itself and emit a double-buzzer alarm in case of 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.

5. Tabletop material requirements: flat surface, even color, sturdy, no irritating odor, 16mm thickness, and must meet international or domestic environmental standards, conforming to E1 environmental grade. Formaldehyde emission less than 1.5mg/L.
6. The left/middle/right folding screen panels are made of 16mm thick plates, featuring flat surfaces, even coloration, durability, and no irritant odor. The materials must comply with international or domestic environmental protection standards and meet E1 environmental grade.
7. The table body material cutting edges are bordered 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 profile cutting surface must not exceed or protrude beyond the table's outer surface to ensure no cuts to the body during use.
8. To ensure the overall stability and aesthetics of the lift chair, the overall fixed screws are designed to be concealed.
9. The升降card table is made of E1-grade 25mm particleboard, with the surface covered in fire-retardant laminate and the edges crafted with a ya mouth design. Formaldehyde emissions are 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 (activated after the screen is raised, serving as a protective barrier), regular teaching state (screen lowered)
12. Each desktop 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), and the power on/off or USB insertion can be directly operated on the desktop for convenience and speed.
