Claims

1. A high-load, high-precision, multi-stage folding and telescopic device, characterized in that: The system includes a base, a square tube profile, a movable carrier plate, a telescopic drive belt, pulleys, pulley mounting seats, a telescopic drive gear, a telescopic drive rack, a telescopic drive motor, and a telescopic drive reducer. The square tube profile is slidably connected to the base. The telescopic drive motor is connected to the telescopic drive reducer. The output shaft of the telescopic drive reducer passes through the base and is connected to the telescopic drive gear. The telescopic drive gear meshes with the telescopic drive rack installed at the bottom of the square tube profile. The movable carrier plate is slidably connected to the square tube profile. The pulleys are respectively installed at both ends of the square tube profile via pulley mounting seats. A first drive belt clamp is provided at the bottom of the tail end of the movable carrier plate. Both ends of the base are provided with... The upper section of the telescopic drive belt passes between the square tube profile and the movable carrier plate and is connected to the first drive belt clamp. One end of the telescopic drive belt extends below the square tube profile after being guided by one set of pulleys and is fixed on one of the second drive belt clamps. The other end of the telescopic drive belt extends below the square tube profile after being guided by another set of pulleys and is fixed on another second drive belt clamp. The telescopic drive motor can drive the square tube profile to move horizontally through the telescopic drive gear and the telescopic drive rack. The square tube profile can also drive the movable carrier plate to move horizontally relative to the square tube profile through the telescopic drive belt.
