Abstract

The invention discloses a rapid angle adjusting device for a projection lamp. The rapid angle adjusting device comprises a fixed support and a first rotary disc, the top of the fixed support is rotatably connected with the first rotary disc through a rotary shaft screw, the first rotary disc is uniformly provided with through holes in the circumferential direction, a positioning device connected with the through holes are arranged on the fixed support, and the two ends of the first rotary disc are connected with a second rotary disc and a third rotary disc correspondingly; and the second rotary disc and the third rotary disc are connected with a lamp assembly correspondingly. The positioning device is pulled out, and the first rotary disc is rotated when an angle needs to be adjusted; andthe positioning device is loosened and then fixed with the through holes when a required angle is reached, then angle adjusting is completed, and the operation is convenient and rapid. The rapid angleadjusting device for the projection lamp is simple in structure, the purpose of angle adjusting is achieved through the cooperation of the positioning device and the through holes in the rotary discs, the angle adjusting is convenient and other tools are not needed, so that accurate positioning is realized.

Description

technical field [0001] The invention relates to the technical field of floodlights, in particular to a quick angle adjustment device for floodlights.
