Description

Technical Field

[0001] The invention relates to the technical field of stage lighting, and in particular to a stepless cutting structure and a stage light thereof. Background Art

[0002] Existing stage light cutting devices are used to rotate and cut a light beam to obtain a pattern of a specific shape. However, the cutting device uses many electrical devices, such as a drive motor and a circuit board. These connecting wires are easily entangled, resulting in twisted wires, broken wires, and wire obstruction of rotation. To address the above technical drawbacks, a conductive slip ring assembly is installed on the cutting device. The conductive slip ring assembly includes a first slip ring plate and a second slip ring plate, which are arranged in an upper and lower position. The first slip ring plate is connected to a fixed plate, and the second slip ring plate is connected to a rotating cutting disk assembly. The first slip ring plate and the second slip ring plate are electrically connected in a sliding manner via a conductive brush. When the rotating cutting disk assembly rotates, the second slip ring plate rotates synchronously with the rotating cutting disk assembly, while the first slip ring plate remains stationary. The first slip ring plate and the second slip ring plate maintain a sliding electrical connection. However, this conductive slip ring assembly has a poor load-bearing capacity, which is not conducive to stable operation and the conductive connection is unstable. Summary of the Invention

[0023] As attached Figure 1 and attached Figure 2 As shown, a stepless cutting structure and its stage light include a fixed plate 1, a first rotating conductor 2, a second rotating conductor 3 and a cutter 4, wherein the fixed plate 1 is fixedly connected to the upper end of the first rotating conductor 2, and the lower end of the second rotating conductor 3 is fixedly connected to the cutter 4, the first rotating conductor 2 is rotatably sleeved on the outer periphery of the second rotating conductor 3, and the first rotating conductor 2 and the second rotating conductor 3 are electrically connected, and a driving member 5 is fixed on the second rotating conductor 3, and the driving member 5 is linked to the teeth of the first rotating conductor 2 through a synchronous belt 6, so that the cutter 4 rotates around the first rotating conductor 2. The first rotating conductor 2 and the second rotating conductor 3 can rotate relative to each other while maintaining conductivity, allowing the cutter to rotate at any angle. The first rotating conductor 2 and the second rotating conductor 3 are in an internal and external rotating structure, which not only supports, protects and bears the weight of the cutter 4, but also maintains balance and stable power supply. In addition, the driving member 5 and the synchronous belt 6 cooperate in transmission to make the mechanical transmission efficient and stable.

[0024] As attached Figure 3 and attached Figure 4As shown, the cutter 4 includes a circuit board 41, a cutting motor 42, a cutting plate 43 and a cutting assembly 44 arranged from top to bottom. The cutting plate 43 is fixedly connected to the lower end of the second rotating conductor 3. The circuit board 41 is mounted on the cutting plate 43 through a first support column 45, so that there is a spacing space 40 between the circuit board 41 and the cutting plate 43. The cutting motor 42 is fixedly mounted on the cutting plate 43 and is located in the spacing space 40. The cutting assembly 44 is fixedly connected to the lower end of the cutting plate 43. The layout of the various components of the cutting structure is reasonable and the structure is more compact.

[0025] As attached Figure 5 As shown, the first rotating conductor 2 is axially penetrated by a wire hole 21 for passing an external power cord. A first integrated wire body 7 is fixedly mounted at the lower end of the first rotating conductor 2. One end 71 of the first integrated wire body 7 is electrically connected to the power cord, while the other end 72 maintains electrical contact with the outer periphery of the second rotating conductor 3. The second rotating conductor 3 is provided with a second integrated wire body 8 extending from its lower end. The cutting plate 43 is provided with a wire opening 431. The extended end of the second integrated wire body 8 passes through the wire opening 431 and is electrically connected to the circuit board 41. First, after passing through the wire hole 21 through which the external power cord passes, the second integrated wire body 8 is electrically connected to one end 71 of the first integrated wire body 7, while the other end 72 maintains electrical connection with the rotating second rotating conductor 3. Then, the second integrated wire body 8 passes through the wire opening 431 and is connected to the circuit board 41, thereby completing the power supply to the circuit board 41. This ensures an orderly layout of the wires in the cutting structure, preventing wire tangling, wire breakage, and wire obstruction of rotation.

The dust cover 9 is fixedly connected to the lower end of the second rotating conductor 3 through the annular transverse portion 91, and the annular vertical portion 92 surrounds the outer periphery of the second rotating conductor 3, so that the first integrated wire body 7 is located between the annular vertical portion 92 and the second rotating conductor 3. The dust cover 9 can effectively block dust, allowing the first integrated wire body 7 to maintain effective electrical contact with the outer periphery of the second rotating conductor 3 for a long time.

[0028] As attached Figure 4 As shown, the driving member 5 is mounted on the cutting plate 43 via a second support column 51 to facilitate the fixing and installation of the driving member 5 .
