Title: STABLE AND SAFE MECHANICAL LIFTING PLATFORM
Abstract:
Disclosed is a stable and safe mechanical lifting platform. The platform comprises a base plate (1). Threaded rods (2) are inserted into two ends at the top of the base plate (1) in a threaded manner. Fixed plates (3) are fixedly mounted to two sides of the base plate (1). Threaded plates (4) in threaded connection with the threaded rods (2) are rotationally connected on the fixed plates (3). Limiting blocks (5) located at side faces of the fixed plates (3) are movably connected to two sides of the threaded plates (4), and side faces of the two limiting blocks (5) are fixedly connected by means of a supporting shaft (6) penetrating through the threaded plates (4). Limiting mechanisms (7) are fixedly mounted to two sides of an inner cavity of the base plate (1). Side faces of the two limiting mechanisms (7) are connected in a sliding manner by means of a lifting board (8). According to the platform, by means of arranging the threaded plates, the threaded rods and the base plate, the threaded plates, after being manually driven to rotate, can drive the threaded rods to move up or down by means of the engagement with the threaded rods, thus achieving the effect that the threaded rods can be inserted into the ground to keep the base plate and the ground relatively stable, and then achieving the effect of improving the stability and safety of the lifting platform.
