Solar street lamp and lamp arm assembly

Abstract

The invention discloses a solar street lamp and a lamp arm assembly. The Lamp arm assembly comprises a sleeve, and the right end of the sleeve is connected with a second connecting piece; clamping teeth are arranged on the periphery of the edge of the inner side of the second connecting piece, the second connecting piece is round, a hole is formed in the middle of the second connecting piece, thesecond connecting piece is connected with the first connecting piece through a connecting piece fixing screw and a connecting piece fixing nut, clamping tooth grooves are formed in the periphery of the edge of the inner side of the first connecting piece, and the clamping tooth grooves are matched with the clamping teeth. The invention discloses the solar street lamp and the lamp arm assembly, theclamping teeth and the clamping tooth grooves are arranged in the first connecting piece and the second connecting piece, through clamping and meshing of the clamping teeth and the clamping tooth grooves, the street lamp has the angle adjusting function and is convenient to adjust, the connecting piece fixing nut is properly unscrewed, a proper gap is reserved between the clamping teeth and the clamping tooth grooves, the angle can be easily adjusted, and the connecting piece fixing nut is screwed after the angle is adjusted.

Description

technical field [0001] The invention belongs to the technical field of street lamps, and in particular relates to a solar street lamp, and at the same time, the invention also relates to a lamp arm assembly of the solar street lamp. Background technique [0002] Road lights can improve traffic conditions, effectively reduce driver fatigue at night, and help improve road capacity and ensure traffic safety. In the prior art road lamps, the light source is usually fixed on the lamp housing, and then the lamp housing is fixed by the lamp arm. Thus, the direction of the light emitted by the light source cannot be changed. However, in practical applications, due to different road conditions or different surrounding environments, light in different directions is often required, so the road lights in the prior art cannot adapt to different road conditions and environments, and the number of current street light modules is fixed. It cannot be increased or decreased. If there is a c...

However, in practical applications, due to different road conditions or different surrounding environments, light in different directions is often required, so the road lights in the prior art cannot adapt to different road conditions and environments, and the number of current street light modules is fixed. It cannot be increased or decreased. If there is a change, the entire lamp must be replaced.
