Abstract

The invention discloses an electric lifting mechanism which comprises a sleeve pipe, an electric pushing rod, a pulley and a steel wire rope wound on the pulley. The sleeve pipe comprises an outer pipe, a middle pipe and an inner pipe from outside to inside in sequence. An electric pushing rod fixing part and a steel wire rope fixing part are arranged at the bottom of a pipe cavity of the outer pipe. A middle pipe upper lining sleeve is fixedly arranged at the top of the pipe cavity of the outer pipe. A middle pipe lower lining sleeve is arranged at the bottom of the middle pipe in a sleeved mode. An inner pipe upper lining sleeve is fixedly arranged at the top of a pipe cavity of the middle pipe. An inner pipe lower lining sleeve is arranged at the bottom of the inner pipe in a sleeved mode. An inner pipe lower flange is arranged at the lower end of the inner pipe. The inner pipe lower flange is placed below the inner pipe lower lining sleeve. The electric pushing rod comprises a pushing rod base and a pushing rod body. The pushing rod base is fixed on an electric pushing rod fixing part. The pulley is fixed at the top of the pushing rod. One end of the steel wire rope is fixed at a steel wire rope fixing part. The other end of the steel wire rope is connected with the inner pipe lower flange. The electric lifting mechanism is simple in structure, stable in lifting and operation and low in manufacturing cost.

Description

technical field

[0001] The invention relates to a lifting mechanism, in particular to an electric lifting mechanism of a light box. Background technique

[0002] At present, most of the LED screen light boxes used in the market cannot be adjusted in height, and lack special lifting adjustment devices. However, some known lifting structures have the disadvantages of complex structure, difficult maintenance, high manufacturing cost, and uneven lifting operation. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide an electric lifting mechanism with simple structure, stable lifting operation and low manufacturing cost.

[0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

[0005] An electric lifting mechanism, including a casing, an electric push rod, a pulley and a steel wire rope wound on the pulley; the casing includes an outer tube,...
