Switching device for adjusting lamp installation angle, a 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 and a connecting main body which are rotatably connected, wherein the fixed part is provided with first wheel teeth and a first gear part, the first wheel teeth and gear teeth on the first gear part form a first gear plate with continuous gear teeth, the connecting main body is provided with second wheel teeth and a second gear part, the second wheel teeth and gear teeth on the second gear part form a second gear plate with continuous gear teeth, the first gear plate can be meshed with the second gear plate, the first and second wheel teeth are formed by pressure casting of aluminum alloy, and the first and second gear parts are made of high-hardness materials. Compared with the prior art, the switching device for adjusting the lamp installation angle has the advantages that when the switching device works, the high-hardness materials are meshed with aluminum alloy, or the high-hardness materials are meshed with each other, so that the first and second gear plates are not easy to abrade, the service life can be prolonged, higher strength can be borne, and the application range can be enlarged.

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...
