In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

As shown in fig. 1, the present utility model provides a remotely-and regularly-operable automatic lifting platform, comprising:

a lifting structure and a controller 2;

the lifting structure comprises:

In order to ensure that the height range of the adjustable point of the elevator is as large as possible, each side of the elevator is mutually connected by using 4 basic units to form a multi-layer scissor-type structure, and the uppermost part of the elevator is connected with a loading platform 6, and the structure of the elevator is the same as that of the bottom plate 1. The left and right ends of the connecting rod 5 are respectively fixed at one ends of the scissor arms 3 at the left side and the right side, the height is the middle of the multilayer scissor structure, and the two connecting rods 5 are fixed at the front and back positions of the same height and are connected through the motor 4. Since the lifting and lowering of the scissor fork structure requires the use of a force perpendicular to the lifting and lowering direction, a direct-current push rod motor 4 is used, the push rod motor 4 is placed transversely, and the direction of the force applied by the push rod motor 4 is perpendicular to the lifting and lowering direction of the lifting platform. When the push rod motor 4 stretches out of the push rod, the distance between the front connecting rod 5 and the rear connecting rod 5 is increased, and the scissor structure is driven to compress up and down, so that the lifting platform descends; when the push rod motor 4 contracts the push rod, the distance between the front connecting rod 5 and the rear connecting rod 5 is reduced, and the scissor structure is driven to compress left and right, so that the lifting platform ascends. The structure of the lifting mechanism is bilateral and symmetric, the lifting mechanism is vertically symmetric, and the height adjusting range is 30-75cm.
