Switching device for adjusting lamp installation angle, lighting device and switching device

Abstract

The invention provides a switching device for adjusting a lamp installation angle, a lighting device and another switching device. The switching device for adjusting the lamp installation angle comprises a fixed part connected with a lamp, a connecting main body connected with a lamp post, and an anti-loose screw, wherein the fixed part is rotatably connected with the connecting main body by a first screw, the fixed part is provided with an arc-shaped through hole for allowing the anti-loose screw to penetrate through, the connecting main body is provided with a threaded hole, the anti-loose screw penetrates through the arc-shaped through hole to be matched with the threaded hole, and the screwing directions of the anti-loose screw and the first screw are opposite. Compared with the prior art, the switching device for adjusting the lamp installation angle has the advantages that the screwing directions of the anti-loose screw and the first screw are opposite, when external force, such as wind, acts on the switching device, the anti-loose screw and the first screw are stressed by the acting force in the same direction, as the screwing directions of the anti-loose screw and the first screw are opposite, one of the anti-loose screw and the first screw is loosened, while the other of the anti-loose screw and the first screw is certainly tightened, and the switching device is prevented from being loosened and falling off.

Description

technical field [0001] The invention relates to the technical field of adapter devices, in particular to an adapter device for adjusting the installation angle of a lamp, a lighting device and the adapter device. Background technique [0002] Most of the existing lamps cannot adjust the installation angle, and the elevation angle of the light pole cannot be adjusted. Therefore, when the lamp is used on light poles with different roads and different elevation angles, the angle cannot be adjusted. In order to solve the above problems, there is currently a lamp cap installation angle adjustment device, which includes a fixed base, a rotating base, a connecting piece passing through the rotating base and the fixing base, and a locking piece that locks the connecting piece; the connecting piece Follow the rotating seat to rotate and cooperate with the fixed seat in a clearance; the rotating seat is embedded with an inner gear plate that is threadedly connected with the connecting...
