As shown in fig. 1 to 4, a circular rotation structure for a spot lamp includes an inner ring 10 and an outer ring 20, wherein the outer wall of the inner ring 10 is provided with a buckle 11 and a first protrusion 12 protruding outward, the inner wall of the outer ring 20 is provided with an annular groove 21 corresponding to the buckle 11, and the inner wall of the outer ring 20 is provided with a second protrusion 22 corresponding to the first protrusion 12;

the inner ring 10 is nested in the outer ring 20 and the snap 11 is snapped into the annular groove 21.

Specifically, the inner ring 10 and the outer ring 20 are both cylindrical and are vertically through, the outer diameter of the inner ring 10 is smaller than the inner diameter of the inner ring 10, and the inner ring 10 is nested in the outer ring 20. The outer wall of the inner ring 10 is provided with the buckle 11 protruding outwards, the inner wall of the outer ring 20 is provided with an annular groove 21 corresponding to the buckle 11 at a corresponding position, when the inner ring 10 is nested inside the outer ring 20, the buckle 11 is clamped in the annular groove 21, the buckle 11 and the annular groove 21 are responsible for realizing the connection between the inner ring 10 and the outer ring 20, and the inner ring 10 can rotate around the central axis thereof relative to the outer ring 20 after being mounted. The outer wall of the inner ring 10 is provided with a first lug 12 protruding outwards, and the inner wall of the outer ring 20 is provided with a second lug 22 protruding towards one side of the circle center of the outer ring 20 at a corresponding position; when the inner ring 10 is installed on the outer ring 20, the first projection 12 and the second projection 22 are in the same horizontal position; the first protrusions 12 and the second protrusions 22 function to limit the inner ring 10 from rotating more than 360 ° relative to the outer ring 20, that is, when the inner ring 10 rotates to a certain angle and the first protrusions 12 and the second protrusions 22 are abutted, the first protrusions 12 and the second protrusions 22 limit the inner ring 10 from rotating continuously, so that the inner ring 10 can only rotate in the opposite direction.

The circular rotation structure is mainly used in embedded lamps such as spot lamps, down lamps and ceiling lamps, and particularly, the main body part of the lamp is fixedly installed with the inner ring 10, and the main body part of the lamp and the inner ring 10 can rotate for a certain angle relative to the outer ring 20. In the existing recessed light fitting, generally, the light fitting main body part can rotate relative to the outer ring, because the outer ring plays a role in connecting and fixing with other components in the installation process, for example, in a ceiling light, the outer ring needs to be responsible for fixedly connecting with a ceiling. The main body part of the lamp can rotate relative to the outer ring, and the position of the main body part of the lamp is adjusted properly when the lamp is convenient to mount and wire connection. In the prior art, most of the recessed lamps can rotate more than 360 ° relative to the outer ring, which brings certain risks: the lamp body can rotate at will, which causes the winding of the power line connecting the lamp source inside the lamp and the external power supply, thereby causing danger. In the technical scheme, the outer wall of the inner ring 10 is provided with a first bump 12 protruding outwards, the inner wall of the outer ring 20 is provided with a second bump 22 corresponding to the first bump 12, and the first bump 12 and the second bump 22 are matched to limit the inner ring 10 to rotate more than 360 degrees relative to the outer ring 20, so that the lamp body mounted on the inner ring 10 is limited to rotate less than 360 degrees relative to the outer ring 20, and the situation that the lamp body can rotate freely and a power line is wound is avoided. The present disclosure may adjust the rotatable angle of the inner ring 10 by setting the lengths of the first protrusion 12 and the second protrusion 22, for example, increasing the length of the first protrusion 12 or the second protrusion 22 or both to decrease the rotatable angle of the inner ring 10.

In some prior art lamps, in order to solve the same problem, a rotation angle limiting component may be combined with a component connecting an inner ring and an outer ring, such as the first protrusion 12 is disposed on the buckle 11, and then the second protrusion 22 is disposed in the annular groove 21; however, this method has the following problems: firstly, the processing and production are inconvenient, secondly, the assembly is inconvenient, and thirdly, the parts are easy to damage. In the technical scheme, the first bump 12 is arranged on the outer wall of the inner ring 10, the second bump 22 is arranged on the inner wall of the outer ring 20, so that the first bump 12 and the second bump 22, the buckle 11 and the annular groove 21 are independently opened, and a part playing a rotating role and a part playing a rotation limiting role do not interfere with each other, thereby facilitating the processing and the production and the assembly, and meanwhile, the first bump 12 and the second bump 22 are directly arranged on the side walls of the inner ring 10 and the outer ring 20, so that the structure is more stable and is not easy to damage.

The top surface 1121 and the bottom surface 1122 are perpendicular to the deformation portion 111, and then are perpendicular to the side wall of the annular groove 21 after the inner ring 10 and the outer ring 20 are assembled, so that the buckling portion 112 is more stably clamped in the annular groove 21, and the inner ring 10 and the outer ring 20 are more stably connected. In the assembly of the inner ring 10 and the outer ring 20, the inner ring 10 is generally nested in the outer ring 20 from top to bottom, so that the inclined surface 1123 can play a gradual role in the assembly process, so that the force applied by the outer ring 20 on the buckle 11 is gradually increased, and the buckle 11 is slowly deformed, thereby avoiding the situation that the buckle 11 is suddenly stressed, broken and the assembly quality is influenced.
