[0002] In the prior art stage lamp, the bottom of the shaft core is fixedly connected to the base, and the top of the shaft core is fixedly connected to the base by passing screws through the transmission gear. When the motor drives the transmission gear through the pulley, the screws are prone to loosening, which is not conducive to locking the transmission gear, bearing assembly and other parts on the shaft core, and is prone to cause mechanical failure. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A fixing structure of a stage light rotating device includes a base and a body, wherein the base is provided with an axis core fixedly connected to the bottom thereof, the middle portion of the axis core is rotatably connected to the body via a bearing assembly, the upper portion of the axis core is threadedly connected with a nut, a circumferential surface of the nut is provided with a hollow groove penetrating from the circumferential surface to a hole thereof in a radial direction, so that the hollow groove separates part of the nut into an upper extrusion layer and a lower extrusion layer, the upper extrusion layer and the lower extrusion layer are both provided with opposite screw holes, and screws for extruding the upper extrusion layer and the lower extrusion layer to deform are provided in the screw holes.

[0006] As a preferred embodiment, it is further defined as: a transmission wheel located below the nut is fixedly provided on the upper part of the shaft core, a plurality of latching protrusions are provided on the inner side of the transmission wheel, a plurality of latching grooves corresponding to the latching protrusions are provided on the upper part of the shaft core, and the transmission wheel is circumferentially fixedly connected to the latching grooves through the latching protrusions.

[0007] As a preferred embodiment, it is further defined that the shaft core is clamped on top of the nut through a first clamping spring.

[0008] As a preferred embodiment, it is further defined that the bottom of the shaft core is clamped with the base via a second clamping spring.

[0009] As a preferred embodiment, it is further defined that the bearing assembly includes a bearing seat, a spacer sleeve and two bearings, the bearing seat is fixedly connected to the machine body, the shaft core is rotatably connected to the bearing seat through the two bearings, and the spacer sleeve is sleeved on the shaft core and located between the two bearings.

[0010] After adopting the above technical scheme, the invention has at least the following beneficial effects: there is a hollow groove between the upper extrusion layer and the lower extrusion layer, so that the upper extrusion layer and the lower extrusion layer have a certain flexibility and are easy to deform; therefore, in the process of screw locking, the upper extrusion layer and the lower extrusion layer are close to each other, and at this time the upper extrusion layer and the lower extrusion layer produce longitudinal deformation, so that the internal thread on the nut and the external thread of the shaft core produce stress in the longitudinal direction and squeeze each other, and at the same time, the upper extrusion layer and the lower extrusion layer will also undergo transverse deformation, so that the internal thread on the nut and the external thread of the shaft core produce stress in the transverse direction and squeeze each other, and the fixing structure makes the teeth of the thread have more bite force, so that the nut is not easy to loosen, thereby ensuring the effective coordination between the components on the shaft core and reducing the mechanical failure rate.

[0018] As attached Figure 1 To Attachment Figure 5As shown, a fixing structure of a stage light rotating device includes a base 1 and a body 2, wherein the base 1 is provided with an axis core 3 fixedly connected to the bottom thereof, the middle portion of the axis core 3 is rotatably connected to the body 2 via a bearing assembly 4, a nut 5 is threadedly connected to the upper portion of the axis core 3, a hollow groove 50 is provided on the circumference of the nut 5, which penetrates from the circumference along the radial direction to the hole thereof, so that the hollow groove 50 separates part of the nut 5 into an upper extrusion layer 51 and a lower extrusion layer 52, the upper extrusion layer 51 and the lower extrusion layer 52 are both provided with opposite screw holes 53, and the screw holes 53 are provided with screws 6 for extruding the upper extrusion layer 51 and the lower extrusion layer 52 to deform; specifically, the upper extrusion layer 51 and the lower extrusion layer 52 are provided with screws 6 for extruding the upper extrusion layer 51 and the lower extrusion layer 52 to deform; There is a hollow groove 50 between 52, so that the upper extrusion layer 51 and the lower extrusion layer 52 have a certain flexibility and are easy to deform; therefore, during the tightening process of the screw 6, the upper extrusion layer 51 and the lower extrusion layer 52 move closer to each other, and at this time, the upper extrusion layer 51 and the lower extrusion layer 52 produce longitudinal deformation, so that the internal thread on the nut and the external thread of the shaft core produce stress in the longitudinal direction and squeeze each other. At the same time, the upper extrusion layer 51 and the lower extrusion layer 52 will also undergo transverse deformation, so that the internal thread on the nut and the external thread of the shaft core produce stress in the transverse direction and squeeze each other. This fixed structure makes the teeth of the thread more engaging, making the nut less likely to loosen, thereby ensuring the effective coordination between the components on the shaft core 3 and reducing the mechanical failure rate.

[0020] As attached Figure 3 and attached Figure 4 As shown, the shaft core 3 is clamped on the nut 5 by a first clamping spring 8, and the first clamping spring 8 further prevents the nut from loosening.

[0021] As attached Figure 3 As shown, the bottom of the shaft core 3 is clamped with the base 1 through a second clamping spring 9 , and the second clamping spring 9 is mainly used to prevent the shaft core 3 from escaping from the mounting hole of the base 1 .

[0022] As attached Figure 2 To Attachment Figure 4As shown, the bearing assembly 4 includes a bearing seat 41, a spacer sleeve 42 and two bearings 43. The bearing seat 41 is fixedly connected to the body 2. The shaft core 3 is rotatably connected to the bearing seat 41 through the two bearings 43.
