Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rotational locking mechanisms, and in particular to a rotational locking mechanism for a lighting device. Background Art
[0002] At present, the LED track lights on the market are mainly composed of a lamp body, a connecting rod, an electrical box and a track; the lamp body is assembled into a spotlight unit that can rotate in the horizontal and vertical directions through the connecting rod and the electrical box. After the spotlight unit is installed in the track, it can be powered on and lit. The lamp body in the spotlight device can rotate up and down 90 degrees in the vertical direction. When the lamp body needs to rotate in the horizontal direction, if there is a limit structure between the connecting rod and the electrical box, the angle that the lamp body can rotate in the horizontal direction is less than 360 degrees. In this way, there will be a blind spot for illumination. If there is no limit structure between the connecting rod and the electrical box, the lamp body can rotate indefinitely in the horizontal direction. As the number of rotations increases, the wires in the electrical box are easily twisted off, which will cause damage to the spotlight device. Summary of the invention
