Abstract

A lamp lifting device (A) comprises a housing, a motor (11) disposed in the housing, a control circuit, a rotary disk (20) capable of rotating clockwise or counterclockwise driven by the motor (11), and a wire (23) wound on the rotary disk (20). The wire (23) has one end connected to the control circuit, and has the other end extending out of the housing and connected to a lamp (24). Clockwise rotation and counterclockwise rotation of the rotary disk (20) are controlled to move the wire (23) connected to the lamp vertically, so as to lift the lamp (24), thereby lifting the lamp (24) conveniently. In scenarios such as a stage, a control program may be set to lift different lamps (24) to different positions at different speeds, thereby producing a more desirable visual effect.

Description

LIGHTING EQUIPMENT DEVICE This application claims priority to Chinese Patent Application No. 2011-20187117.7, entitled "Lamp Lifting Device", which is incorporated herein by reference. Technical field

The utility model relates to the technical field of installation of a lamp, in particular to a lamp lifting device.

Background technique

In places such as the stage or building lobby and mobile performances, in order to enhance the visual effect, people generally use the means of changing the color and brightness of the lamps, but if the lamps can be lifted and lowered at will, it will bring better visual effects. At present, there is no machine in the prior art that can lift and lower the lamps. To realize the lifting and lowering of the lamps, the manual operation is often performed, which makes the lamps unable to rise and fall at will, and the lifting is inconvenient. Summary of the invention

In view of this, the object of the present invention is to provide a lamp lifting device capable of arbitrarily lifting and lowering a lamp. In order to solve the above technical problem, the technical solution of the present invention is: a lamp lifting device, comprising: a casing and a motor disposed in the casing, a control circuit, a turntable that can be rotated forward and reverse under the driving of the motor, and a turntable disposed on the turntable The upper wire is connected to the control circuit at one end and to the lamp outside the outer casing. Preferably, a transmission mechanism is disposed between the turntable and the motor. Preferably, the transmission mechanism is a timing pulley. Preferably, the motor is a stepper motor. Preferably, the motor is disposed on a motor bracket. Preferably, the timing pulley comprises a large synchronous wheel, a small synchronous wheel and a timing belt. The large synchronous wheel is fixed to the turntable through a shaft core and a bearing, and the small synchronous wheel is connected to the motor output shaft. Preferably, the outer casing includes a mating cover, a bottom plate, a front plate, a rear plate, and a pair of side plates. Preferably, the bottom plate is provided with a through hole for the wire to pass through. Preferably, the control circuit is disposed on a circuit board. Compared with the prior art, the utility model comprises a casing, a motor disposed in the casing, a control circuit, a turntable that can be rotated forward and reverse under the driving of the motor, and a wire wound around the turntable. The controller is connected, and the other end is connected to the lamp outside the outer casing. Therefore, the wire connecting the lamp can be moved up and down by controlling the forward rotation and the reverse rotation of the turntable, thereby realizing the lifting and lowering of the lamp, and the lamp can be conveniently lifted and lowered conveniently. In the occasions such as the stage, the control program can be set so that different lamps can be raised and lowered to different positions at different speeds, resulting in better visual effects.

In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to Fig. 1, there is shown a schematic structural view of a preferred embodiment of the lamp lifting device of the present invention. The lamp lifting device of the embodiment includes a casing, a stepping motor disposed in the casing, a synchronous pulley, a turntable, and a control circuit.

The outer casing is composed of a matching cover plate 1, a bottom plate 13, a side plate 2, a cassette fixing plate 4, and a shaft fixing plate 3, 7.

A motor 11 is provided in the housing, a motor frame 6 for fixing the motor 11, and a motor mount 12 for adjusting the motor 11. A turntable 20 is disposed in the outer casing, and a turntable pillar 21 is disposed thereon, and the turntable 20 is fixed to the large synchronous wheel 17 of the timing pulley through the shaft cores 19, 22 and the bearing housing 18. The small timing wheel 14 of the timing pulley is fixed to the output shaft of the motor 11. The large synchronizing wheel 17 and the small synchronizing wheel 14 are connected by a timing belt 15. A carbon brush 8 and a carbon brush fixing plate 9 are also arranged beside the motor 11. The control circuit is placed on the boards 5, 10. An optocoupler disk 16 is also disposed beside the small synchronous wheel. The bottom plate 13 is provided with a through hole for the power supply line 23 to extend and is connected to the lamp.
