Street lamp with height and angle adjustment function

Abstract

The invention discloses a street lamp with a height and angle adjustment function. The street lamp comprises a fixing base. The upper side of the fixing base is fixedly connected with a supporting rod which is internally provided with a mobile groove with an opening rightwards formed. The mobile groove is internally provided with a mobile block which is internally provided with a vertically formed threaded through hole. The threaded through hole is internally in threaded connection with a threaded rod. The top end and the bottom end of the threaded rod are both rotatably connected with the supporting rod. The bottom of the threaded rod is fixedly provided with a first bevel gear. The left side of the first bevel gear is engaged with a second bevel gear. The street lamp has the beneficial effects that the first bevel gear drives the threaded rod to rotate, and the mobile block matched with the threaded rod moves up and down in the mobile groove, so that vertical adjustment of a lamp cap is achieved, and lamp cap repair is facilitated; and LED lamp bodies generate much heat during work, and when the LED lamp bodies work, the contact area between a cooling fin and air is effectively increased through additionally arranged first-stage fin bodies and second-stage fin bodies, and the cooling effect is greatly improved.
