[0021] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, the LED spotlight rotation mechanism described in the present invention comprises a lamp holder 1, a lamp frame 11 and a light-emitting module 12, wherein the light-emitting module 12 is arranged on the lamp frame 11, and a slewing ring 2 is arranged on the lamp holder 1, and the lamp frame 11 is connected with the slewing ring 2 in cooperation; a plurality of bending buckle plates 13 are arranged on the outer edge of the upper port of the lamp holder 1, and an outer ring piece 21 is arranged at the lower end of the slewing ring 2, and the outer ring piece 21 is inserted between the plurality of bending buckle plates 13 and the upper port of the lamp holder 1, and a plurality of bending buckle plates 13 are arranged on the lamp holder 1 to be connected with the outer ring piece 2 1 cooperates with a stop card 3; the slewing ring 2 is used to connect the lamp holder 11 and the lamp base 1, and a plurality of bent buckle plates 13 and the upper end of the lamp base 1 form an annular slide groove, so that the outer ring piece 21 can rotate horizontally on the upper end of the lamp base 1, so that the slewing ring 2 and the lamp holder 1 thereon can rotate 360 ​​degrees, and the lamp holder 11 can adjust the elevation angle of the light-emitting module 12, so that with the cooperation of the slewing ring 2, a larger area can be covered, and the stop card 3 is used to lock the slewing ring 2 and the lamp base 1 after the adjustment is completed.

[0023] A supporting ring 14 is provided in the upper end of the lamp holder 1, and a plurality of stamping openings 15 are opened on the supporting ring 14 at equiangular intervals, and a bending buckle plate 13 is provided on the stamping opening 15, and an outer ring piece 21 is rotatably inserted between the supporting ring 14 and the bending buckle plate 13; the supporting ring 14 forms a rotating platform at the upper end of the lamp holder 1 to support the slewing ring 2, the outer diameter of the outer ring piece 21 is larger than the inner diameter of the supporting ring 14, and the inner diameter of the outer ring piece 21 is smaller than the inner diameter of the supporting ring 14, the bending buckle plate 13 cooperates with the supporting ring 14 to clamp the outer ring piece 21 and form a sliding fit with the supporting ring 14, so that the slewing ring 2 and the lamp holder 1 are connected as a whole and the slewing ring 2 can be rotated on the lamp holder 1; the bending buckle plate 13 and the supporting ring 14 structure on the lamp holder 1 can be realized by injection molding or stamping molding, which is convenient to process and has low cost.

[0024] The stop card 3 can move horizontally along the inner wall of the lamp holder 1. The upper end of the stop card 3 is provided with a fixing piece 31, and the fixing piece 31 is in sliding cooperation with the supporting ring 14. The front end of the fixing piece 31 is provided with a spring piece 32, and the spring piece 32 is placed below one of the punching openings 15.

The bottom surface of the outer ring piece 21 is provided with a plurality of scale grooves 22. When the stop card 3 is in the normal state, the spring piece 32 is in the punching opening 15, and the convex point on the spring piece 32 does not contact the supporting ring 14. Therefore, the spring piece 32 can rise freely and be hooked to the outer ring piece 21 through the hook tooth 33. The slewing ring 2 is then locked in the graduated groove 22. When rotation adjustment is required, the stop card 3 is pushed away from the stamping opening 15 to retract the spring clip 32 under the support ring 14. The convex point on the spring clip 32 contacts the support ring 14 and is compressed. The spring clip 32 is pressed downward to disengage the hook tooth 33 from the graduated groove 22. Then the slewing ring 2 can be freely rotated for angle adjustment. After the adjustment is completed, the stop card 3 is pushed to lock the slewing ring 2 again. The spring clip 32 cooperates with the stop card 3 to conveniently lock and unlock the slewing ring 2. The operation is relatively convenient.
