Problems solved by technology
The lamp body in the spotlight device can rotate 90 degrees up and down in the vertical direction, and 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 lamp body will rotate horizontally. The angle at which the direction can be rotated is less than 360 degrees. In this way, there will be a blind angle of irradiation. If there is no limit structure between the connecting rod and the electrical box, the lamp body can rotate without limit in the horizontal direction. The increase in the number of times will easily break the wires in the electrical box, which will cause damage to the spotlight device

The invention discloses a rotary clamping mechanism for a lighting device. The rotary clamping mechanism comprises a base and a connecting rod rotationally connected to the base, wherein the end faceof the side, facing the connecting rod, of the base is provided with a stop block, the end face of the side, facing the base, of the connecting rod is provided with a fan ring groove corresponding tothe stop block, the fan ring groove and the connecting rod are coaxially arranged, the stop block is located outside the fan ring groove, the fan ring groove is internally provided with a limiting block sliding along the fan ring groove, the end, facing the base, of the limiting block stretches out of the fan ring groove, after the connecting rod rotates, the end, facing the base, of the limitingblock can abuts against the stop block, and the length of the fan ring groove is greater than the sum of the width of the stop block and width of the limiting block. The rotary clamping mechanism forthe lighting device has the advantages that by adopting the above structure, after a lamp body is installed on the connecting rod, the lamp body not only can perform rotational motion more than 360 degrees in the horizontal direction to arbitrarily adjust the irradiation angle of the lamp body, but also can avoid the phenomenon that a wire is twisted off due to the excessive rotation of the lamp body.
Description
technical field [0001] The invention relates to the technical field of a rotary clamping mechanism, in particular to a rotary clamping mechanism for an illuminating device. Background technique [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 spotlight can be powered on after being installed in the track as a whole. The lamp body in the spotlight device can rotate 90 degrees up and down in the vertical direction, and 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 lamp body will rotate horizontally. The angle at which the direction can be rotated is less than 360 degrees. In this way, there will be a blind angle of irradiation. If there is no limit structure between the connecting rod and the electrical box, the lamp body can rotate without limit in the horizontal direction. As t...
