Detailed Description

The present invention is discussed in detail below with reference to fig. 1-4.

An electric lifting support for a liquid crystal display is mainly composed of a bottom seat plate (1), a stand column (2), a back plate (3), a roller (4), a linear bearing (5), a U-shaped component (6), a movable pulley (7), a fixed pulley (8), a steel wire rope (9), a driving mechanism motor, a roller (10), an upper cover (11) and a guide rail (12). The electric lifting support for the display is characterized in that the electric lifting support for the display is arranged on a base plate (1) at the bottom of a stand column (2), a motor and a roller (10) are respectively arranged outside and inside the stand column (2) and fixed on the base plate (1) at the bottom of the stand column, a lifting mechanism is arranged inside the stand column (2), a fixed pulley (8) is arranged on the front inner side of the top end of the stand column (2), guide rails (12) C and D are respectively arranged on the front inner side and the back inner side of the stand column (2), and an upper cover (11) is arranged at the top of the stand column (2).

An upright post (2) is fixed on a bottom seat plate (1) and is fixed by bolts and the like, a motor of a driving mechanism (10) is fixed on the bottom seat plate (1), the outer side of the lower end of the upright post (2) is fixed on the bottom seat plate (1), a roller is fixed inside the upright post (2), the motor is connected with the roller, one end of a steel wire rope (9) is fixed on the roller, the steel wire rope (9) is collected or discharged through the positive and negative rotation of the motor, a linear bearing is vertically fixed on the inner side of the front surface of the upright post (2) by bolts and the like, a movable sliding block of the linear bearing faces the back surface of the upright post (2), 4 guide rails (12) are respectively positioned on the inner walls of the positive and negative surfaces of the upright post (2), the left side and the right side of the linear bearing, 4 guide rails are symmetrically arranged, a U-shaped component (6) B end is fixed on the sliding block, 2 rollers at the front surface of the B end ride on a guide rail (12) C on the inner wall of the front surface of the upright post (2), (6) 4 gyro wheels of B end back ride and press on guide rail (12) D, U type component (6) A end is fixed with bolt etc. for backplate (3), backplate (3) are connected with bolt etc. for the display, 2 fixed pulleys locate stand (2) inner wall upper end left and right sides, the other end of wire rope (9) is through 2 fixed pulleys, 1 movable pulley is fixed in U type component (6) B end upper portion, respectively is equipped with 1 limit switch in stand (2) upper end and lower extreme.
