As shown in fig. 1, the rotating electrical machine 2 is mounted on the bracket 1, the driving wheel 3 is mounted on the other side of the bracket 1, and the central shaft of the driving wheel 3 is connected with the rotating shaft of the rotating electrical machine 2, so that the rotating electrical machine 2 can drive the driving wheel 3 to rotate. The driven wheel 4 is mounted on the bracket 1 and is arranged at the side end of the driving wheel 3. The automatic winder 5 is mounted on the bracket 1 and is disposed above the driving wheel 3. One end of the electric wire 6 is wound into the automatic winder 5 and connected to the automatic winder 5, and the other end thereof is extended out of the holder 1 and connected to the base 8. The electric wire 6 comes out from the automatic winder 5 and passes through a guide wheel set 7, the driving wheel 3 and the driven wheel 4 in sequence, and the terminal is connected with the lamp cap 8.

The working process of the utility model is as follows: when the lamp holder 8 needs to be lowered, the rotating motor 2 drives the driving wheel 3 to rotate, the wire 6 is pulled out, and meanwhile, the lamp holder 8 moves downwards under the action of the gravity of the lamp holder 8. When the lamp holder 8 needs to be lifted, the rotating motor 2 rotates in the direction to drive the driving wheel 3 to rotate, so that the lamp holder 8 is pulled upwards by the wire 6, and meanwhile, the withdrawn electrons are drawn into the automatic winder 5.

According to the lifting device provided by the embodiment of the utility model, the electric wire 6 is pulled out and retracted through the rotating motor 2, so that the lamp cap 8 is lowered and raised, the automatic winder 5 is arranged to be involved in the retracted electric wire 6, and two directional wheel sets are arranged so that the lamp cap 8 is raised and lowered more stably. Therefore, the lifting device provided by the embodiment of the utility model has a simple structure, can effectively realize the lifting of the lamp holder 8, and can display various lamp effects.

Illustratively, the electric wire 6 is wound in an S-shape around the driving pulley 3 and the driven pulley 4. The entry of the electric wire 6 of the driving wheel 3 is arranged below the outlet of the electric wire 6 of the automatic winder 5, and the entry of the electric wire 6 of the driven wheel 4 is arranged obliquely above the outlet of the driving wheel 3, so that the electric wire 6 is S-shaped, and the electric wire 6 is kept in a tightening state.

Exemplarily, the guide wheel set 7 is installed on the bracket 1, the guide wheel set 7 is arranged between the driven wheel 4 and the lamp holder 8, the guide wheel set 7 comprises two rotating wheels, the wire 6 is arranged between the two rotating wheels and is abutted against the two rotating wheels, so that the two rotating wheels play a certain guiding and positioning role on the wire 6, and the lamp holder 8 can ascend and descend more stably.

Illustratively, the number of the guide wheel sets 7 is two, and another guide wheel set 7 is arranged between the driving wheel 3 and the automatic winder 5, so as to play a certain guiding and positioning role for the electric wire 6.

Illustratively, as shown in fig. 2, the automatic winder 5 is provided with a spool 51 to which the electric wire 6 is connected and a clockwork spring 52 that can drive the spool 51 to rotate, thereby allowing the electric wire 6 to be more smoothly drawn out or retracted from the automatic winder 5.

Illustratively, the driving wheel 3 is provided with a V-shaped groove having a concave-convex pattern, thereby increasing the friction between the driving wheel 3 and the electric wire 6 and preventing the electric wire 6 from slipping. It is conceivable that the groove may also be U-shaped or semicircular, and the contact surface of the groove and the motor may also be a smooth surface.

Exemplarily, the rotating motor 2 is set as a servo motor, which is beneficial to realizing the accurate control of the lifting height of the lamp holder 8. And when the rotating motor 2 is a stepping motor, the production cost can be reduced.
