Novel erecting locking and unlocking mechanism

The utility model relates to a novel erecting locking and unlocking mechanism which is suitable for achieving the erecting locking and unlocking function on an erecting lifting system installed on a high-precision instrument platform and belongs to the field of mechanical design. The novel erecting locking and unlocking mechanism comprises a motor, a motor speed reducer, a coupler, a bearing, a locking block and a screw. The coupler is fixed through the bearing, the motor drives the motor speed reducer and the coupler to drive the screw to rotate, the left end and the right end of the screw are provided with left-hand threads and right-hand threads respectively, and the screw drives the locking block to move through spiral transmission. The novel erecting locking and unlocking mechanism is compact in structure, small in needed installation space, high in reliability, capable of achieving locking and unlocking motions rapidly, waterproof and dustproof.
