Detailed Implementation

[0024] Example 1

[0025] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3A pluggable pattern disk device for stage lighting includes a lamp body 2 with a stepped hole 21 on its outer surface, and a pluggable pattern disk assembly 1 that is seamlessly connected to the lamp body 2 through the stepped hole 21. The lamp body 2 contains a light source 25, a drive motor 23, and a drive gear 22. The drive motor 23 and drive gear 22 are mounted in the light-emitting direction and located on one side of the light source 25, without obstructing the light emitted from the light source 25. One end of the pluggable pattern disk assembly 1 is a rotating pattern gear seat 11 with an image receiving cavity 111, and the other end is a handheld part 141 for easy operation of the pluggable pattern disk assembly 1. By operating the handheld part 141, the pluggable pattern disk assembly 1 is inserted into the lamp body 2 through the stepped hole 21, so that the receiving cavity 111 of the rotating pattern gear seat 11 reaches a predetermined position, ensuring that the center of the image 113 coincides with the main optical axis 251. The pluggable pattern disk assembly 1 is magnetically fixed to the lamp body 2, and the rotating pattern gear seat 11 is meshed with the drive gear 22. When the pluggable pattern disk assembly 1 and the stepped hole 21 on the outer surface of the lamp body 2 are fully fitted, a smooth transition without gaps is formed between the outer surfaces of the two, realizing the seamless connection between the pluggable pattern disk assembly 1 and the lamp body 2; at this time, the rotating pattern gear seat 11 is meshed with the drive gear 22 to ensure that the center of the rotating pattern gear seat 11 can coincide with the main optical axis 251; when the drive gear 22 transmits the kinetic energy of the drive motor 23 to the rotating pattern gear seat 11, the rotating pattern gear seat 11 can rotate on the main optical axis 251 and project a patterned light spot.

[0026] Traditional pattern disc devices are usually fixedly installed inside the lamp body, and the entire lamp needs to be disassembled for replacement, making it difficult to quickly switch pattern discs and limiting the diversity of lighting effects.

[0027] Therefore, this utility model proposes a pluggable pattern disk device, which allows for quick replacement of different imaging objects 113 via a pluggable pattern disk. In this embodiment, the pluggable pattern disk assembly 1 is magnetically fixed to the lamp body 2, achieving a pluggable connection with the lamp body 2. When the handle 141 is grasped and the pluggable pattern disk assembly 1 is pulled out, the pluggable pattern disk assembly 1 exits the lamp body 2 along the stepped hole 21 and disengages from the drive gear 22. At this time, the imaging object 113 on the pluggable pattern disk assembly 1 can be replaced with other different imaging objects 113, or even more... Replace with other effect plates that have different effects; when the handle 141 is held and the pluggable pattern plate assembly 1 is inserted into the lamp body 2 through the stepped hole 21, the pluggable pattern plate assembly 1 is in close contact with the stepped hole 21, and the pluggable pattern plate assembly 1 can be firmly attached to the lamp body 2, preventing the pluggable pattern plate assembly 1 from sliding out of the lamp body 2; the rotating pattern gear seat 11 is located on the main optical axis 251 and is meshed with the drive gear 22; at this time, the lamp with the pluggable pattern plate assembly 1 can quickly change the image object 113 to form a variety of light output effects.

[0028] The beneficial effect of this embodiment is that the pluggable pattern disk assembly 1 is securely installed in the lamp body 2 through a magnetic structure, realizing the plug-and-play function; the design of the pluggable pattern disk assembly 1 allows users to directly plug and unplug different imaging objects 113 or effect sheets, breaking through the limitations of traditional fixed installation and significantly improving the switching efficiency of stage lighting effects.

[0029] As a new implementation method, combined with the appendix Figure 2 and attached Figure 3 The lamp body 2 is also provided with a guide slide 24. The guide slide 24 includes a guide slide groove 241 located in the middle, positioning wings 242 located on both sides and adjacent to the guide slide groove 241, and a magnet groove 243 for installing magnets on the positioning wings 242. The magnet groove 243 is located on the side of the positioning wings 242 away from the handheld part 141. The guide slide 24 has a through rectangular guide slide groove 241, with the opening of the guide slide groove 241 located on opposite sides of the guide slide 24; the first magnet groove 243 is circular and located on both sides perpendicular to the opening direction of the guide slide groove 241; the first magnet groove 243 is located on the positioning wings 242 protruding on both sides of the guide slide 24, that is, on opposite sides of the positioning wings 242, one side has the first magnet groove 243, and the other side is a flat surface; the lower surface of the guide slide 24 has three mounting grooves, and the guide slide 24 is locked to the fixing post through the mounting grooves, and then installed inside the lamp body 2 through the fixing post; it can be understood that the guide slide 24 can also be installed on the inner surface of the lamp body 2; while the pluggable pattern disk assembly 1 is fitted into the guide slide groove 241, the pluggable pattern disk assembly 1 is magnetically fixed to the positioning wing 242 to realize the positioning of the pluggable pattern disk assembly 1. The beneficial effect of this embodiment is that when the pluggable pattern disk assembly 1 is fitted into the guide slide groove 241, it is magnetically fixed to the positioning wing 242, thereby achieving precise positioning and vibration-resistant installation of the pluggable pattern disk assembly 1 in the lamp body 2.

[0030] As a new implementation method, combined with the appendix Figure 1 Appendix Figure 2 and attached Figure 3The guide groove 241 and the stepped hole 21 are mated to form a channel 4 through which the rotating pattern gear seat 11 passes. The guide member 24 is a rectangular box, and the guide groove 241 is provided through the guide member 24. The openings of the guide groove 241 are located on opposite sides of the guide member 24, and the opening at one end is mated to the stepped hole 21 on the lamp body 2. The stepped hole 21 on the outer surface of the lamp body 2 is a strip-shaped stepped hole, which is adapted to the guide groove 241. The guide groove 241 is connected to the outside through the stepped hole 21 and forms a smooth transition channel 4 with the stepped hole 21. When it can be inserted When the pluggable pattern disk assembly 1 is inserted into the lamp body 2, it passes through the stepped hole 21 and is pushed into a predetermined position along the guide groove 241, that is, it is inserted into the lamp body 2 through the channel 4, thus engaging with the drive gear 22. At this time, the center of the image object 113 in the rotating pattern gear seat 11 coincides with the main optical axis 251. When the pluggable pattern disk assembly 1 is pulled out of the lamp body 2, it moves out of the lamp body 2 along the channel 4 and disengages from the drive gear 22. The beneficial effect of this embodiment is that the guide groove 241 and the stepped hole 21 form a smoothly transitioning channel 4, which facilitates the smooth insertion or removal of the pluggable pattern disk assembly 1 into or out of the lamp body 2 along the channel 4.

[0031] As a new implementation method, combined with the appendix Figure 2 Appendix Figure 4 and attached Figure 5The pluggable pattern disk assembly 1 also includes a support base 12 located in the middle, mounting plates 13 located on both sides of the support base 12 and connected to the support base 12, and an arc-shaped cover plate 14. The support base 12 is slidably fitted into the guide groove 241, and the rotating pattern gear seat 11 is installed through and mounted on the end of the mounting plate 13 away from the support base 12. The support base 12 has a rectangular structure and is provided with a through hole for mounting the mounting plate 13. The mounting plate 13 is locked onto the support base 12 through the through hole. The mounting plate 13 is a flat plate, located on the side of the support base 12 away from the handle part 141, and the arc-shaped cover plate 14 is located on the side of the support base 12 closer to the handle part 141. The end of the mounting plate 13 away from the stepped hole 21 is used to mount the rotating pattern gear seat 11, and the end closer to the stepped hole 21 is locked onto the support base 12. The size of the mounting plate 13 is smaller than... The size of the stepped hole 21 is smaller than that of the guide groove 241, which facilitates the smooth passage of the mounting plate 13 and the support 12 through the channel 4 formed by the stepped hole 21 and the guide groove 241. The support 12 is fitted into the guide groove 241, and its size is adapted to the guide groove 241. The gear of the rotating pattern gear seat 11 is located below the mounting plate 13. The rotating pattern gear seat 11 and the drive gear 22 are meshed and connected below the mounting plate 13. Furthermore, the rotating pattern gear seat 11 is unobstructed, which allows for better heat dissipation. The beneficial effect of this embodiment is that the fit between the support 12 and the guide groove 241 facilitates the stable installation of the pluggable pattern disk assembly 1 inside the lamp body 2. The rotating pattern gear seat 11 is installed through the mounting plate 13, which facilitates the smooth passage of the pluggable pattern disk assembly 1 through the channel 4 into the lamp body 2. The arc cover plate 14 is in close contact with the stepped hole 21, which facilitates the formation of a smooth transition without gaps on the outer surfaces of the arc cover plate 14 and the stepped hole 21.

[0032] As a new implementation method, combined with the appendix Figure 5 The support base 12 is also provided with a groove 121 for mounting the mounting plate 13. One end of the mounting plate 13 near the support base 12 is locked to the bottom of the groove 121. The groove 121 is a rectangular groove with openings on three sides, and the bottom of the groove 121 has multiple threaded holes. One end of the mounting plate 13 has a through hole corresponding to the threaded holes at the bottom of the groove 121. The mounting plate 13 is locked to the bottom of the groove 121 by fasteners passing through the through holes. Since the support base 12 and the guide groove 241 are size-matched, the mounting plate 13 cannot exceed the upper surface of the support base 12, and the groove depth of the groove 121 is greater than the combined height of the mounting plate 13 and the fasteners. The beneficial effect of this embodiment is that the mounting plate 13 does not exceed the upper surface of the support base 12, which does not hinder the support base 12 from sliding into the guide groove 241, and facilitates the smooth insertion or removal of the pluggable pattern disk assembly 1 along the guide groove 241.

[0033] As a new implementation method, combined with the appendix Figure 1 and attached Figure 5 The arc-shaped cover plate 14 covers the stepped hole 21, and the handle 141 is located on the outer surface of the arc-shaped cover plate 14. Magnet slots 142 for installing magnets are provided at both ends of the inner surface of the arc-shaped cover plate 14, and the magnet slots 142 are adjacent to the support base 12. The shape and size of the stepped hole 21 on the lamp body 2 are adapted to the arc-shaped cover plate 14, and the depth of the stepped hole 21 is the same as the thickness of the arc-shaped cover plate 14. Therefore, after the arc-shaped cover plate 14 and the stepped hole 21 are fitted together, a smooth transition is formed between the arc-shaped cover plate 14 and the outer surface of the lamp body 2, achieving seamless insertion of the pluggable pattern plate assembly 1 and the lamp body 2. The handle 141 is a semi-circular flat plate located in the middle of the outer surface of the arc-shaped cover plate 14. By pinching the handle 141, the pluggable pattern plate assembly 1 can be inserted into the lamp body 2. The tray assembly 1 is inserted into or removed from the lamp body 2; the second magnet groove 142 is a circular groove with its opening facing the main optical axis 251, and the magnet is fixed to the second magnet groove 142 by adhesive; the length of the second magnet groove 142 is less than the width of the support base 12, so that when the second magnet groove 142 is engaged with the guide slide 24, the arc-shaped cover plate 14 of the insertable pattern tray assembly 1 can just fit tightly with the step hole 21, and the second magnet groove 142 does not prevent the support base 12 from being fitted into the guide slide groove 241. The beneficial effect of this embodiment is that the external handle part 141 of the arc-shaped cover plate 14 facilitates the insertion and removal operation, and the built-in magnetic attraction structure achieves a stable fixation, effectively preventing the insertable pattern tray assembly 1 from loosening.

[0034] As a new implementation method, combined with the appendix Figure 3 The second magnetic groove 142 corresponds one-to-one with the positioning wing 242, and the second magnetic groove 142 is in close contact with the positioning wing 242. Both the first magnetic groove 243 and the second magnetic groove 142 are circular grooves, and a circular magnet is installed in each groove. The first magnetic groove 243 uses magnetic attraction to form a stable connection between the positioning wing 242 and the pluggable pattern disk assembly 1, while the positioning wing 242 performs a positioning function to ensure the accurate positioning of the pluggable pattern disk assembly 1. The second magnetic groove 142 provides the attraction force between the pluggable pattern disk assembly 1 and the guide slide 24. When the pluggable pattern disk assembly 1 is inserted into the predetermined position along the guide slide 241, the second magnetic groove 142 and the positioning wing 242 form a magnetic positioning. The number of the first magnetic groove 243, the second magnetic groove 142 and the positioning wing 242 are equal and correspond one-to-one, and their shapes are adapted to ensure the stable installation and accurate alignment of the pluggable pattern disk assembly 1. The beneficial effect of this embodiment is that the number of magnet slots 142 and positioning wings 242 are equal and their positions are opposite and they are in close contact with each other, thereby ensuring the accurate positioning and stable fixation of the pluggable pattern disk assembly 1 in the lamp body 2.

[0035] As a new implementation method, combined with the appendix Figure 3 and attached Figure 6The support base 12 is fitted into the guide groove 241, forming a clearance fit with the guide groove 241. The support base 12 has a rectangular structure, and the guide groove 241 is also rectangular. The size of the support base 12 is slightly smaller than the size of the guide groove 241, which facilitates the smooth sliding insertion or removal of the support base 12 into the guide groove 241. The guide groove 241 is adjacent to the stepped hole 21. The stepped hole 21 is used to limit the pluggable pattern disk assembly 1, and the guide groove 241 is used to guide the pluggable pattern disk assembly 1 to be inserted radially. Since the size difference between the guide groove 241 and the support base 12 is not significant, the guide groove 241 can prevent the pluggable pattern disk assembly 1 from shaking after being inserted into the lamp body 2, thus affecting the light output effect of the lamp. The beneficial effect of this embodiment is that the support base 12 and the guide groove 241 form a clearance fit, the support base 12 can be smoothly inserted into or pulled out of the guide groove 241, and when the support base 12 is located in the guide groove 241, the insertable and removable pattern disk assembly 1 will not shake.

[0036] As a new implementation method, combined with the appendix Figure 6 The rotating pattern gear seat 11 is also provided with an elastic element 112 for pressing the imaging object 113. The elastic element 112 is locked in the receiving cavity 111 and located above the imaging object 113. In this embodiment, the elastic element 112 is a spring, and the diameter of the spring is equal to the inner diameter of the receiving cavity 111. The receiving cavity 111 is a circular cavity, and the spring can be firmly locked in the receiving cavity 111. The imaging object 113 is installed at the bottom of the receiving cavity 111. The imaging object 113 is a circular plate, and its diameter is slightly smaller than the inner diameter of the receiving cavity 111. When the imaging object 113 needs to be replaced, the spring is first removed from the receiving cavity 111. At this time, the spring no longer presses the imaging object 113. The imaging object 113 can be removed from the receiving cavity 111 by a slight external force after the spring is removed, and replaced with other different imaging objects 113, or other effect sheets with different light emission effects. The beneficial effect of this embodiment is that by using the elastic member 112 to press the imaging object 113, the installation or replacement steps of the imaging object 113 can be simplified, making the installation or replacement of the imaging object 113 more convenient.

[0037] Example 2

[0038] The difference between Embodiment 2 and Embodiment 1 is that the fixing method of the pluggable pattern disk assembly 1 is different.

[0039] Combined with appendix Figure 7The support base 12 has an arc-shaped cover plate 14 on one side that covers the stepped hole 21. The arc-shaped cover plate 14 is locked onto the lamp body 2, and a waterproof adhesive strip 3 is provided between the arc-shaped cover plate 14 and the lamp body 2. The arc-shaped cover plate 14 has mounting holes at both ends for fixing, and the stepped hole 21 has mounting holes on both sides corresponding to the mounting holes of the arc-shaped cover plate 14. The arc-shaped cover plate 14 is directly locked onto the lamp body 2 through the mounting holes, and the waterproof adhesive strip 3 is arranged along the edge of the stepped hole 21. When the pluggable pattern disc assembly 1 is inserted into the lamp body 2, the arc-shaped cover plate 14 covers the stepped hole 21 and is tightly attached to the waterproof adhesive strip 3, forming a sealed waterproof cavity together with the lamp body 2. The beneficial effect of this embodiment is that the arc-shaped cover plate 14 is locked onto the lamp body 2, and the waterproof adhesive strip 3 is provided between the arc-shaped cover plate 14 and the lamp body 2, improving the waterproof performance of the lamp and extending its service life.

[0040] The working principle of the technical solution of this utility model is explained as follows, as shown in the appendix. Figure 1 To be continued Figure 7 As shown, the pluggable pattern disk assembly 1 of this utility model is inserted into the channel 4 formed by the lamp body step hole 21 and the guide groove 241. During this process, the support seat 12 is tightly fitted with the inner wall of the guide groove 241, which helps to prevent the rotating pattern gear seat 11 from shaking on the main optical axis 251.

[0041] In Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, the arc-shaped cover plate 14 covers the step hole 21 and is fixed to the guide slide 24 by the built-in magnet groove 142, thereby locking it with the lamp body 2 and effectively preventing the pluggable pattern disk assembly 1 from sliding out.

[0042] In Example 2, as shown in the appendix Figure 7 As shown, the arc-shaped cover plate 14 covers the stepped hole 21 and is locked onto the lamp body 2 through the mounting hole on the arc-shaped cover plate 14. A waterproof strip 3 is also provided between the lamp body 2 and the arc-shaped cover plate 14, which can effectively prevent the pluggable pattern plate assembly 1 from sliding out and effectively improve the waterproof performance of the lamp.

[0043] The rotating pattern gear seat 11 of the pluggable pattern disk assembly 1, which is fully inserted into the lamp body 2, automatically aligns with the main optical axis 251 and meshes with the drive gear 22, ensuring that the drive gear 22 transmits precisely and that the axis of the rotating pattern gear seat 11 is completely coincident with the main optical axis 251, thus achieving a stable installation of the pluggable pattern disk assembly 1 and a natural transition between the outer surface of the arc cover plate 14 and the outer surface of the lamp body 2.
