Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically, to a stage lamp with a waterproof supporting arm. Background Art

[0002] For stage lights that do not require waterproofing, the driver components are usually placed inside the arm to save space inside the lamp head and base. The driver components of most waterproof stage lights on the market are placed inside the lamp head and base, and then the lamp head and base are waterproofed. The arm is used to connect to the outside world to help dissipate heat. However, with the popularity of laser light sources, the optical path is shortened, the lamp head is getting smaller, and the internal space of the base is getting more compact. In addition, the large base will greatly reduce the overall aesthetics of the lamp. Utility Model Content

[0003] In order to overcome at least one defect of the prior art, the utility model provides a stage light with a waterproof support arm, and provides a closed cavity for installing a motor and other components, thereby effectively reducing the volume of a base.

The driving force of the horizontal motor is transmitted to the first synchronous wheel through the first transmission belt, and the first sleeve can rotate relative to the first pivot shaft, then under the drive of the horizontal motor, the arm rotates around the first pivot shaft, that is, the arm drives the lamp head to rotate relative to the base.

[0010] Furthermore, the lamp holder is fixedly connected with a second pivot shaft inserted into the vertical bracket, and further comprises a second sleeve fixedly connected to the vertical bracket, and a second synchronous wheel fixedly sleeved on the second pivot shaft, a third synchronous wheel fixedly sleeved on the vertical motor driving shaft, and a second transmission belt sleeved on both the second synchronous wheel and the third synchronous wheel, all located on the vertical bracket, and the second sleeve is sleeved on the pivot shaft through a second bearing. The third synchronous wheel transmits the driving force of the vertical motor to the second synchronous wheel through the second transmission belt, and the second synchronous wheel is connected to the second pivot shaft, and the second sleeve can rotate relative to the second pivot shaft, and finally, under the drive of the vertical motor, the lamp holder rotates relative to the arm.

[0011] Furthermore, a through hole for the vertical motor drive shaft to pass through is provided on one side wall of the accommodating cavity, and an annular protrusion surrounding the through hole is provided on the outer side wall of the accommodating cavity, and the annular protrusion has a second groove for installing a second waterproof rubber strip. Under the joint action of the annular protrusion and the second waterproof rubber strip, water vapor is effectively prevented from entering the sealed accommodating cavity from the through hole.

[0012] Furthermore, a plurality of reinforcing ribs distributed along the circumference of the connection between the top cover and the bottom cover are provided to ensure a firm connection between the top cover and the bottom cover, and the assembled horizontal bracket can provide sufficient supporting force.

[0013] Furthermore, the base is a sheet metal structure, which is simple in structure and easy to operate, and the entire lamp can be quickly installed on a truss or other stage equipment.
