Technical Field

[0001] This utility model belongs to the technical field of dynamic visual art installations, specifically relating to a mechanical transmission and light and shadow effect linkage mechanism for dynamic visual installations. Background Technology

[0002] In the field of contemporary visual communication art, light and shadow installations have become an important medium for spatial narrative. However, most existing visual light and shadow installations are fixed light and shadow patterns, with relatively simple light and shadow display effects and poor promotion. Utility Model Content

[0003] The purpose of this invention is to provide a mechanical transmission and light and shadow effect linkage mechanism for a dynamic visual device, which can project different light and shadow patterns by utilizing the differential rotation of multiple prisms and a light-transmitting cover, thus enriching the light and shadow projection effect.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A mechanical transmission and light and shadow effect linkage mechanism for a dynamic visual device includes a fixed plate. The inner bottom surface of the fixed plate is rotatably connected to the bottom ends of three fixed rings through bearings. The upper surfaces of the three fixed rings are respectively fixedly connected to the bottom ends of three prisms. The upper end of the fixed plate is threadedly connected to the bottom end of an external threaded tube. The upper surface of the external threaded tube is fixedly connected to the bottom end of a light-transmitting cover through bearings.

[0006] Furthermore, the outer surfaces of the three fixed rings are respectively fixedly connected to the three external toothed rings, and the two inner external toothed rings are respectively meshed with the two gears.

[0007] Furthermore, the two gears are respectively fixedly mounted on the top ends of the two connecting shafts, and the bottom ends of the two connecting shafts are rotatably connected to the inner bottom surface of the fixed disk through bearings.

[0008] Furthermore, the two gears are respectively meshed with two internal gear rings, and the two internal gear rings are respectively fixedly disposed on the inner side of the two outer fixed rings.

[0009] Furthermore, the outermost external gear ring meshes with gear two, which is fixedly mounted on the output shaft of motor one.

[0010] Furthermore, one bottom end of the motor is fixedly connected to the inner bottom surface of the fixed disk.

[0011] Furthermore, a screw hole is provided in the middle of the bottom surface of the fixing plate, the screw hole is threadedly connected to the threaded disc, and the upper surface of the threaded disc is fixedly connected to the bottom end of the lamp post.

[0012] Furthermore, the light-transmitting cover has multiple light-transmitting holes of different shapes, and the bottom end of the inner side of the light-transmitting cover is fixedly connected to an internal gear ring, which meshes with a gear.

[0013] Furthermore, the gear one is fixedly mounted on the output shaft of the motor two, and the motor two is fixedly connected to the inner side of the external threaded tube through a mounting base.

[0014] Furthermore, the bottom surface of the fixed plate is simultaneously fixedly connected to the upper ends of multiple fixed supports.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention features a multi-layered prism and a light-transmitting cover fitted around the outside of a light column. The light-transmitting cover has multiple light-transmitting holes of various shapes. During use, motors one and two drive the multi-layered prisms and the light-transmitting cover to rotate at different speeds. This causes the light emitted from the light column to be refracted by the multi-layered prisms and then pass through the light-transmitting holes at different angles, thus forming dynamic light spots of various shapes and improving the visual communication effect. Furthermore, during use, the user can disassemble and replace the threaded tube and the light-transmitting cover as a whole to adjust the pattern of the projected light spot, further increasing the functionality of the device.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a dynamic visual device uses a mechanical transmission and light and shadow effect linkage mechanism, including a fixed plate 1. The inner bottom surface of the fixed plate 1 is rotatably connected to the bottom ends of three fixed rings 16 through bearings. The upper surfaces of the three fixed rings 16 are respectively fixedly connected to the bottom ends of three prisms 9. The upper end of the fixed plate 1 is threadedly connected to the bottom end of the external threaded tube 2. The upper surface of the external threaded tube 2 is fixedly connected to the bottom end of the light-transmitting cover 3 through bearings.

[0026] The outer surfaces of the three fixed rings 16 are fixedly connected to the three external toothed rings 14 respectively, and the two inner external toothed rings 14 are respectively meshed with the two gears 19.

[0027] Two gears 19 are fixedly mounted on the top of the two connecting shafts 17 respectively. The bottom ends of the two connecting shafts 17 are rotatably connected to the inner bottom surface of the fixed disk 1 through bearings. When the motor 6 is working, it drives multiple fixed rings 16 and polygon mirrors 9 to rotate at different speeds through the meshing transmission of gears 18, gears 19 and multiple internal gear rings 15 and external gear rings 14. When the multiple polygon mirrors 9 rotate to different positions, the light from the lamp post 8 passing through the multiple polygon mirrors 9 is refracted into different angles.

[0028] The two gears 19 are also meshed with the two internal gear rings 15 respectively, and the two internal gear rings are fixedly installed on the inner side of the two outer fixed rings 16 respectively.

[0029] The outermost external gear ring 14 meshes with gear 2 18, which is fixedly mounted on the output shaft of motor 1 6.

[0030] The bottom end of motor 6 is fixedly connected to the inner bottom surface of fixed plate 1.

[0031] A screw hole 10 is provided in the middle of the bottom surface of the fixed plate 1. The screw hole 10 is threadedly connected to the threaded plate 7. The upper surface of the threaded plate 7 is fixedly connected to the bottom end of the lamp post 8. When using this device, the threaded plate 7 can be rotated to separate the threaded plate 7 from the screw hole 10, thereby replacing the lamp post 8 with different brightness and color, and further enriching the projection effect of this device.

[0032] The light-transmitting cover 3 has multiple light-transmitting holes 5 of different shapes. The bottom of the inner side of the light-transmitting cover 3 is fixedly connected to the inner gear ring 11. The inner gear ring 11 is meshed with the gear 13. When the motor 2 12 is working, it drives the light-blocking cover to rotate through the gear 13 and the inner gear ring 11. At this time, the light refracted by the multi-layer prism 9 passes through the constantly rotating light-transmitting holes 5 and projects a dynamic light spot.

[0033] Gear 13 is fixedly mounted on the output shaft of motor 2, and motor 2 is fixedly connected to the inner side of external threaded tube 2 through a mounting base.

[0034] The bottom surface of the fixed plate 1 is simultaneously fixedly connected to the upper end of multiple fixed supports 4.

[0035] The working principle of this utility model is as follows: When this device is running, it can control the lamp post 8, motor 6 and motor 12 to work. When motor 6 works, it drives multiple fixed rings 16 and polyprisms 9 to rotate at different speeds through the meshing transmission of gear 18, gear 19 and multiple internal gear rings 15 and external gear rings 14. When multiple polyprisms 9 rotate to different positions, the light from the lamp post 8 passing through the multiple polyprisms 9 is refracted into different angles. When motor 12 works, it drives the light shield to rotate through gear 13 and internal gear ring 11. At this time, the light refracted by the multiple polyprisms 9 passes through the light-transmitting hole 5 and projects a dynamic light spot.

[0036] When using this device, the user can rotate the external threaded tube 2 to separate the external threaded tube 2 from the fixed plate 1, thereby disassembling and replacing the external threaded tube 2, the light-transmitting cover 3, the internal gear 13, the motor 12, and the gear 13 as a whole. The user can also rotate the threaded plate 7 to separate the threaded plate 7 from the screw hole 10, thereby replacing the lamp post 8 with different brightness and color.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
