[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0019] refer to Figure 1-Figure 2 This embodiment provides a downlight, including a downlight body 1, an inner ring 2 and an outer ring 3; the inner ring 2 and the outer ring 3 are connected by a ball 4, so that the inner ring 2 has a swinging degree of freedom in the vertical direction and a rotational degree of freedom in the horizontal direction relative to the outer ring 3. In this way, the function of the rotating downlight is realized, and the inner ring 2 and the outer ring 3 can be assembled together and then installed with the downlight body 1, which greatly facilitates the installation of the inner ring 2.
[0020] In order to realize the swinging and rotational freedom in the above-mentioned two directions, the outer ring 3 has a cavity for accommodating the inner ring 2, and the inner wall of the cavity is provided with a circle of arc grooves 31 along the circumferential direction, and the outer wall of the inner ring 2 is provided with a positioning groove 21 for installing the ball 4; the ball 4 cooperates with the positioning groove 21 to form a matching structure of a ball head and a ball socket, so that the inner ring 2 has the swinging freedom in the vertical direction relative to the outer ring 3, and the ball 4 cooperates with the arc groove 31 to enable the inner ring 2 to have the rotational freedom in the horizontal direction relative to the outer ring 3.
[0021] In this embodiment, in order to increase the number of balls 4 on the inner ring 2 and the outer ring 3, there are two positioning grooves 21 correspondingly.
[0022] In order to facilitate the installation of the inner ring 2 and the outer ring 3, the inner wall of the outer ring 3 is also provided with a clamping point 32 for the balls 4 to enter the arc groove 31. As long as the balls 4 are aligned with the clamping point 32, one of the balls 4 can be clamped into the clamping point 32, and then the inner ring 2 is rotated and the other ball 4 is clamped into the clamping point 32, the installation of the inner ring 2 and the outer ring 3 can be completed, which is very convenient.
[0023] After the inner ring 2 and the outer ring 3 are assembled, it is sufficient to connect the outer ring 3 and the downlight body 1 . In this embodiment, the outer ring 3 and the downlight body 1 are connected in a rotational manner.
[0024] In order to realize the above-mentioned rotational connection, at least two rotational connectors for connecting the downlight body 1 are provided on the side of the outer ring 3 facing the downlight body 1, and the rotational connectors are rotationally symmetrically arranged along the circumference of the outer ring 3. Specifically, the rotational connector is an L-shaped rib 33, one end of the short side of which is connected to the inner ring 2, and the other end is connected to the long side, so that the long side extends along the circumference of the outer ring 3. A limiting rib 33 cooperating with the L-shaped rib 33 is provided in the downlight body 1. When the outer ring 3 is rotated, the limiting rib 33 can enter from the opening of the L-shaped rib 33, thereby completing the assembly by limiting the L-shaped rib 33.
