AI Technical Summary

Technical Problem

The rotation mechanism of the projector lamp is prone to wear due to friction when frequently used, which reduces the accuracy and stability of the rotation mechanism. It is difficult to achieve precise control of the rotation angle, which affects the uniformity and consistency of the lighting effect.

Method used

A rotating structure including a rough adjustment member and a fine adjustment member is designed. The rough adjustment member is roughly adjusted through the rotation shaft connection between the first bracket and the second bracket, and the fine adjustment member is finely adjusted through the junction contact between the first end and the second end, thereby improving the rotation accuracy and stability.

Benefits of technology

Through the structural settings of rough and fine adjustment, the rotation accuracy and stability of the lamp body are improved, the service life of the projector lamp is extended, and the uniformity and consistency of the lighting effect are improved.

Abstract

The utility model discloses a rotary structure for adjusting the angle of a lamp, which comprises a lamp main body and a rotary mechanism, the rotary mechanism comprises a rough adjustment part and a fine adjustment part, the rough adjustment part comprises a first support and a second support which are connected with the lamp main body, the first support is connected with the second support through a rotary shaft, and the fine adjustment part is connected with the lamp main body through a rotary shaft. The angle of the irradiation direction of the lamp main body is roughly adjusted; wherein the fine adjustment part comprises a first end and a second end, the first end abuts against the first support and is connected with the lamp body, and the first end is connected with the second end through a rotating shaft, meshed with the second end in an abutting mode through meshing teeth and used for fine adjustment of the irradiation direction of the lamp body. Through the structural arrangement of the fine adjustment part and the coarse adjustment part, the problems that the precision and stability of the lamp rotating mechanism are poor are solved.
