In addition, unless otherwise specified, "multiple" means two or more.

[0030] like Figure 1-6 As shown, the rotating pattern plate of the lamp of the embodiment of the utility model comprises a chassis 1, a transmission shaft 2, a main gear 3 and a plurality of driven components 4. When working, the transmission shaft 2 is connected with the transmission component arranged in the lamp, so that the transmission shaft 2 can drive the main gear 3 to rotate, and the driven component 4 is driven to rotate through the main gear 3, and finally the lamp is irradiated with light having a rotating pattern effect.

[0031] The chassis 1 serves as a mounting mechanism for the transmission shaft 2 and the driven component 4 . The chassis 1 has a through hole 11 and a plurality of mounting holes 12 . The through hole 11 is disposed in the middle of the chassis 1 , and the plurality of mounting holes 12 are disposed around the edge of the chassis 1 .

[0032] The transmission shaft 2 is disposed in the through hole 11, and the transmission shaft 2 is perpendicular to the surface of the chassis 1. In the actual installation process, the transmission shaft 2 is connected to the power output end of the driving assembly so that the transmission shaft 2 can rotate.

[0033] The main gear 3 is disposed above the chassis 1, and the main gear 3 is mounted on the outer periphery of the transmission shaft 2. The outer edge of the main gear 3 is provided with first positioning points 31 having the same number as the mounting holes 12. Specifically, the transmission shaft 2 and the inner hole of the main gear 3 are interference fit, so that the transmission shaft 2 can drive the main gear 3 to rotate together.

[0034] A plurality of driven components 4 are arranged on a plurality of mounting holes 12 in a one-to-one correspondence, and the driven components 4 include a pattern piece 41, a sub-gear 42, a rotating shaft 43 fixed to the bottom of the sub-gear 42, and a mounting seat 44, the mounting seat 44 is installed in the mounting hole 12, the mounting seat 44 has a rotating shaft hole 441, the rotating shaft 43 is rotatably arranged in the rotating shaft hole 441, optionally, the rotating shaft 43 is installed in the rotating shaft hole 441 through a bearing, the sub-gear 42 is transmission-connected with the main gear 3, the sub-gear 42 has a pattern piece hole 421 and a groove 422 arranged on the outer edge of the pattern piece hole 421, the pattern piece hole 421 and the groove 422 extend downward through the rotating shaft 43, the outer edge of the pattern piece 41 has a protrusion 411, the pattern piece 411 is installed in the pattern piece hole 421, and the protrusion 411 is correspondingly arranged in the groove 422, and a second positioning point 423 is provided on the sub-gear 42 opposite to the protrusion 411. The light source in the lamp can form a light with a pattern through the pattern sheet 41 .

[0035] like Figure 3 As shown, a protrusion 411 and a second positioning point 423 of a driven component 4 are arranged corresponding to a first positioning point 31 and are located on the same straight line.

[0036] When in use, the pattern piece 41 is installed in the pattern piece hole 421, and the pattern piece 41 is positioned and installed by the protrusion 411 corresponding to the groove 422. The sub-gear 42 is installed on the mounting seat 44 through the rotating shaft 43. The sub-gear 42 is positioned and installed by aligning the second positioning point 423 on the sub-gear 42 with the first positioning point 31 on the main gear 3, so that the installation is convenient. Since the position of the pattern piece 41 can be positioned, the same pattern piece can be configured in multiple lamps to make the pattern effects of the multiple lamps consistent.

[0037] In one embodiment, the chassis 1 further has a positioning hole 13, which is used to install and fix the chassis 1. Passing a fixing member through the positioning hole 13 can install the chassis 1 in the lamp to stabilize the structure.

[0038] like Figure 5 As shown, in one embodiment, the driven assembly 4 further includes a first retaining ring 45, which is disposed in the shaft hole 441 and is fixedly connected to the mounting seat 44, and is located at the bottom of the shaft 43. The first retaining ring 45 has a limiting effect on the shaft 43 to prevent the end of the shaft 43 from extending out of the mounting seat 44.

[0039] Furthermore, the inner diameter of the first retaining ring 45 is smaller than the outer diameter of the rotating shaft 43, and the inner diameter of the first retaining ring 45 is larger than the diameter of the pattern sheet hole 421. The setting of the first retaining ring 45 does not affect the amount of light entering the pattern sheet hole 421, and at the same time plays a role in limiting the rotating shaft 43.

[0040] like Figure 5 As shown, in one embodiment, the driven assembly 4 further includes a second retaining ring 46, which is disposed in the pattern sheet hole 421, and the second retaining ring 46 is fixedly connected to the rotating shaft 43, and the second retaining ring 46 is located below the pattern sheet 41. The second retaining ring 46 has a limiting effect on the pattern sheet 41 to prevent the pattern sheet 41 from slipping out of the pattern sheet hole 421.

[0041] Furthermore, the inner diameter of the second retaining ring 46 is smaller than the outer diameter of the pattern piece 41. The light of the lamp passes through the pattern piece 41 and radiates out from the inner hole of the second retaining ring 46 to form a light with a pattern. Conversely, the light of the lamp can also pass through the pattern piece 41 from the inner hole of the second retaining ring 46 to form a light with a pattern. The specific setting method is determined according to the relative position of the light source of the lamp and the rotating pattern disk.

[0042] In one embodiment, at least ten driven components 4 are provided. The illumination effect is enriched by providing pattern pieces with different patterns.

[0043] Optionally, the rotating pattern plate further includes a bearing 5, which is installed in the through hole 11 and is passed through by the transmission shaft 2. The transmission shaft 2 is installed in the through hole 11 through the bearing 5, so that the transmission shaft 2 can be driven smoothly.

[0044] In one embodiment, the thickness of the secondary gear 42 is equal to that of the main gear 3, and the secondary gear 42 and the main gear 3 are in the same horizontal plane, so that the main gear 3 drives the secondary gear 42 to rotate smoothly.

[0045] In one embodiment, both the main gear 3 and the sub gear 42 are spur gears, and the outer diameter of the main gear 3 is four times greater than the outer diameter of the sub gear 42. The use of spur gears allows for high transmission accuracy and durability, and is easy to process and reduces costs.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
