Lamp angle adjusting mechanism

Abstract

The invention discloses a lamp angle adjusting mechanism. The mechanism comprises an adjustable support. A driving shaft is arranged on the adjustable support in a penetrating and inserting mode. A plurality of driving shaft gears are arranged on the driving shaft and are in engaging connection with a toothed belt. Lock catches are arranged on one sides of the two ends of the toothed belt correspondingly. A clamping groove is formed in the position, located below the adjustable support driving shaft gears, in the adjustable support. Arc-shaped rails are arranged in the positions, on the two sides of the clamping groove, in the adjustable support correspondingly. Oblique rails are arranged on one sides of the arc-shaped rails correspondingly. The lamp angle adjusting mechanism has the beneficial effects that the driving shaft drives the driving shaft gears, the driving shaft gears drive the flexible toothed belt, the toothed belt slides in the arc-shaped rails, accordingly, a radiator connecting ring slides in the oblique rails, accordingly, the angle of the radiator connecting ring is changed, and accordingly, the angle of a lamp is adjusted; since the flexible toothed belt is used, the transmission direction is quite flexible; and due to the design, lamp angle adjusting is made stable, the size is small, lamp design is facilitated, and the situation that overlarge adjusting force damages the mechanism is avoided.

Description

Technical field [0001] The invention relates to the technical field of a lamp angle adjustment actuator, in particular to a lamp angle adjustment mechanism. Background technique [0002] The most common lamps rely on screws, rivets and some additional friction-increasing gaskets, relying on the friction after being imprisoned to fix the angle of the lamp, and relying on the outside to push the lamp to change the angle when it needs to be adjusted. This method will cause the optical center to deviate and the angle of the lamp is tight The fixing force is not enough, or too tight to be adjusted, or use a screw or gear, driven by a screwdriver, and a hard link method with a sliding rail. This method has a large structure and too many metal parts are not easy to manufacture quickly, so The present invention provides a lamp angle adjustment mechanism. Summary of the invention [0003] The purpose of the present invention is to provide a lamp angle adjustment mechanism to solve the abo...

Problems solved by technology

[0002] The most common lamps rely on screws and rivets to add friction-increasing gaskets, relying on the friction after confinement to fix the angle of the lamp, and when it needs to be adjusted, rely on the outside to push the lamp to change the angle. This method will cause the optical center to deviate, and the angle of the lamp will be tight. The solid force is not enough, or it is too tight and difficult to adjust, or use a screw or gear, driven by a screwdriver, and a hard link method with a slide rail. This method has a large volume of the mechanism, and too many metal parts are not easy to manufacture quickly, so The invention proposes a lamp angle adjustment mechanism
