Description

Light cutting device for light cutting lamp Technical Field

[0001] The utility model belongs to the technical field of light-cutting lamps, in particular to a light-cutting device for light-cutting lamps. Background Art

[0002] In modern stage lighting, the main principle of imaging systems is to use a cutting device to cut the light beam, forming the beam spot into various shapes such as squares, diamonds, triangles, or projecting various pre-designed patterns. The cutting device includes multiple cutting blades, which move to block part of the light beam to form the predetermined imaging pattern.

[0003] For example, in the cutter assembly of announcement number CN210921226U, the light cutting plate and the driving mechanism of this light cutting assembly are connected by transmission rods for transmission. At the same time, both transmission rods are straight rods. In this transmission method, the two transmission straight rods need to convert the torque of the driving mechanism into thrust. If the bearing assembly runs for a long time, the bearing will become stuck and unable to be pulled. In order to solve the above problem, a light cutting device for a light cutting lamp is proposed.

[0004] Utility Model Content

[0005] The purpose of this utility model is to solve the above problems.

[0006] The technical solution adopted by the utility model is as follows: a light cutting device for a light cutting lamp, comprising:

[0007] A base plate has a circular cavity at its center, and a plurality of rollers are rotatably connected to the upper surface of the base plate;

[0008] A rotating plate is rotatably connected to the middle part of the plurality of rollers, and the left and right sides of the upper surface of the rotating plate are rotatably connected to the first driving pieces, the upper surfaces of the two first driving pieces are rotatably connected to the first driving links, and the ends of the two first driving links are rotatably connected to the lower light-cutting pieces, and the front and rear sides of the upper surface of the rotating plate are rotatably connected to the second driving pieces, the upper surfaces of the two second driving pieces are rotatably connected to the second driving links, and the ends of the two second driving links are rotatably connected to the upper light-cutting pieces, and the first driving link and the second driving link are both arc-shaped structures;

[0009] The cross panel is fixedly installed on the middle part of the upper surface of the roller. A light-transmitting hole is opened in the center of the cross panel, and an aperture component is fixedly installed inside the light-transmitting hole.

[0010] Through the above technical solution, the light shines onto the stage through the light-transmitting hole in the center of the cross panel. The first driving plate rotates to drive the first driving connecting rod connected to its upper end to move along its trajectory, thereby driving the lower light-cutting plate at one end to move left and right along the cross panel. Similarly, the second driving plate drives the upper light-cutting plate to move up and down to cut the light. Since the driving connecting rod adopts an arc structure, the force lost in the torque conversion process is smaller, and it itself is less affected by the torque, thereby ensuring that the light-cutting device will not break or jam after long-term use. The size of the aperture is changed by extending or opening the aperture component.

[0011] In a preferred embodiment, the cross panel is located at the upper end of the upper light cutting plate, and the upper light cutting plate is located at the upper end of the lower light cutting plate.

[0012] In a preferred embodiment, an arc groove is formed on one side of each of the first driving plate and the second driving plate, and a plurality of limiting rods are integrally provided on the upper surface of the rotating plate, and the limiting rods are arranged inside the arc groove.

[0013] Through the above technical solution, the maximum movement trajectory of the first drive plate and the second drive plate is limited by the limiting rod and the arc groove.

[0014] In a preferred embodiment, a rack is fixedly mounted on the upper surface of one side of the base plate, and a gear is rotatably connected to the upper surface of one side of the rotating plate, and the rack and the gear are meshed.

[0015] Through the above technical solution, the rotating plate is driven to rotate on the substrate by the rotation of the gear, and is combined with the light cutting device to switch different types of pattern effects.

[0016] In a preferred embodiment, the first drive plate, the second drive plate and the gear are all driven by a motor.

[0017] In a preferred embodiment, a plurality of mounting seats are provided on the outer wall of the substrate.

[0018] The above technical solution makes it easy to install the cutting device.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention provides a light cutting device for a light cutting lamp.

[0020] The rotation of the first driving plate drives the first driving connecting rod connected to its upper end to move along its trajectory, thereby driving the lower light-cutting plate at one end to move left and right along the cross panel. Similarly, the second driving plate drives the upper light-cutting plate to move up and down to cut the light. Since the driving connecting rod adopts an arc structure, the force lost in the torque conversion process is smaller, and it itself is less affected by the torque, thereby ensuring that the light-cutting device will not break or jam after long-term use.

[0026] Example:

[0027] A light cutting device for a light cutting lamp, comprising:

[0028] The substrate 1 has a circular cavity at its center. A plurality of rollers 2 are rotatably connected to the upper surface of the substrate 1.

The rack 14 and the gear 15 are engaged. The rotation of the gear 15 drives the rotating plate 3 to rotate on the substrate 1, and is combined with the light cutting device to switch different types of pattern effects.

The ends of the two first driving links 5 are rotatably connected to the lower light-cutting pieces 6. The front and rear sides of the upper surface of the rotating plate 3 are rotatably connected to the second driving pieces 7. The upper surfaces of the two second driving pieces 7 are rotatably connected to the second driving links 8. The ends of the two second driving links 8 are rotatably connected to the upper light-cutting pieces 9. The first driving link 5 and the second driving link 8 are both arc structures. The first driving link 5 and the second driving link 8 are both arc structures. The rotation of the first driving piece 4 drives the first driving link 5 connected to its upper end to follow its trajectory, thereby driving the lower light-cutting piece 6 at one end to move left and right along the cross panel 10. Similarly, the second driving piece 7 drives the upper light-cutting piece 9 to move up and down to cut the light. Since the driving link adopts an arc structure, the force lost in the torque conversion process is smaller, and the torque itself is also less affected by the torque, thereby ensuring that the light-cutting device will not break or jam after long-term use;

[0030] A cross panel 10 is fixedly mounted on the middle portion of the upper surface of the roller 2. A light-transmitting hole 11 is provided in the center of the cross panel 10. An aperture assembly is fixedly mounted inside the light-transmitting hole 11. The aperture assembly is extended or opened to change the size of the aperture. Light shines onto the stage through the light-transmitting hole 11 in the center of the cross panel 10. The cross panel 10 is located above the upper light-cutting plate 9, which is located above the lower light-cutting plate 6.

[0031] An arc groove 13 is provided on one side of the first drive plate 4 and the second drive plate 7. A plurality of limit rods 12 are integrally provided on the upper surface of the rotating plate 3. The limit rods 12 are arranged inside the arc groove 13. The maximum movement trajectory of the first drive plate 4 and the second drive plate 7 is limited by the limit rods 12 cooperating with the arc groove 13.

[0032] Working principle:

[0033] The light shines onto the stage through the light-transmitting hole 11 in the center of the cross panel 10. The first driving piece 4 rotates to drive the first driving connecting rod 5 connected to its upper end to move along its trajectory, thereby driving the lower light-cutting piece 6 at one end to move left and right along the cross panel 10. Similarly, the second driving piece 7 drives the upper light-cutting piece 9 to move up and down to cut the light. Since the driving connecting rod adopts an arc structure, the force lost in the torque conversion process is smaller, and it itself is less affected by the torque, thereby ensuring that the light-cutting device will not break or get stuck after long-term use.
