[0014] The advantages of implementing the multifaceted prism reflection imaging structure provided by this utility model compared with the prior art are as follows: This invention utilizes an upper prism mechanism and a lower prism mechanism for mutual reflection and imaging.

[0022] Please refer to the following: Figures 1 to 8 The multifaceted prism reflection imaging structure provided in the embodiments of this utility model will now be described.
[0023] like Figures 1 to 8 As shown, the multi-faceted prism reflection imaging structure of this utility model includes an upper prism mechanism 100, a middle shell 200, and a lower prism mechanism 300. The upper prism mechanism 100 includes an outer ring 110 and a first prism device 120. A first screw hole 111 is provided on the top of the outer ring 110. The first prism device 120 is fixedly connected to the outer ring 110 by screws engaging with the first screw hole 111. The middle shell 200 is threadedly connected to the inner wall of the outer ring 110. A light source module 400 is provided inside the middle shell 200. The light source module 400 includes a light source base 410 and a light source shell 420. The light source shell 420 is sleeved on the light source base 300. On the source base 410, a second screw hole 421 is provided on the side of the light source housing 420. The light source housing 420 is fixedly connected to the light source base 410 by screws engaging with the second screw hole 421. A third screw hole 210 is provided on the side of the middle housing 200. The middle housing 200 is fixedly connected to the light source housing 420 by screws engaging with the third screw hole 210. The lower prism mechanism 300 is covered on the bottom of the middle housing 200. A fourth screw hole 320 is provided at the connection between the lower prism mechanism 300 and the middle housing 200. The lower prism mechanism 300 is fixedly connected to the middle housing 200 by screws engaging with the fourth screw hole 320.
[0024] The upper prism mechanism 100, middle housing 200, light source module 400, and lower prism mechanism 300 are modular and detachable, allowing for separate processing. Compared to integrated processing, which involves cutting away excess material from a single piece to obtain the final shape, processing each part separately allows for the production of only the necessary components, resulting in a smaller overall size and weight. Furthermore, different materials can be selected for each part to combine as needed. The first prism device 120 and the middle housing 200 can be processed using non-metallic materials, avoiding the rounded corners that can affect assembly accuracy when using metal parts. The side openings allow the middle housing 200 to be fixedly connected to the light source housing 420, and the light source housing 420 to be fixedly connected to the light source base 410, without affecting each other during assembly.
[0025] like Figure 1 , 3 As shown in Figures 4, 5, and 8, the first prism device 120 has a recessed center forming a first prism cavity 121, and each inner wall of the first prism cavity 121 is provided with a reflecting prism. The reflecting prisms of the first prism cavity 121 are used to receive the light reflected from the lower prism mechanism 300 and finally reflect it to the camera for imaging.
[0026] For example, the outer ring 110 is a metal part, and the first prism device 120 is a plastic part. The outer ring 110 and the first prism device 120 are detachably connected, so they can be processed and assembled using different materials. Using a plastic part for the first prism device 120 can avoid the formation of rounded corners when processing corners, which would cause the gap at the corner splicing of the reflecting prism to be too large and affect the final imaging effect.
[0027] For example, the first prism cavity 121 is shaped like a truncated pyramid, and four reflecting prisms are respectively attached to the four inner walls of the first prism cavity 121. The cavity structure of the truncated pyramid allows the four reflecting prisms to uniformly receive the reflected light from the lower prism mechanism 300 and finally reflect it to the camera for imaging.
[0028] like Figure 3 , 4 As shown in Figures 5 and 7, an LED light source 430 is installed inside the light source housing 420. A light-transmitting cover 440 is provided at the bottom of the light source housing 420. A fifth screw hole 441 is provided at the bottom of the light-transmitting cover 440. The light-transmitting cover 440 is fixedly connected to the light source housing 420 by screws engaging with the fifth screw hole 441. The light-transmitting cover 440 allows the light emitted by the LED light source 430 inside the light source housing 420 to uniformly illuminate the lower prism mechanism 300 or the observed object for supplementary lighting, thereby improving the uniformity of the light.
[0029] like Figures 2-5 As shown, a second prism cavity 310 is provided in the middle of the lower prism mechanism 300, and a reflecting prism is provided on each inner wall of the second prism. The object being observed is placed below the second prism cavity 310, and the emitted light is reflected by the reflecting prism of the second prism cavity 310 to the reflecting prism of the first prism cavity 121, and finally reflected to the camera for imaging.
[0030] like Figures 3-5 As shown, the LED light source 430 is tilted and aligned with the direction of the second prism cavity 310. The tilting setting allows the light from the LED light source 430 to more accurately illuminate the object being tested for supplementary lighting.
[0031] For example, the second prism cavity 310 is octagonal in shape, and eight reflecting prisms are respectively attached to the eight inner walls of the second prism cavity 310. The octagonal shape of the second prism cavity 310 allows the eight reflecting prisms to better receive and reflect light from all directions of the object, resulting in better imaging.
[0032] For example, the middle housing 200 is a 3D printed plastic part. The middle housing 200 is processed by 3D printing plastic parts, avoiding the rounded corners that would occur when processing metal parts, thereby making the middle housing 200 more compact when assembled with other parts of the camera, with smaller assembly gaps and higher assembly precision.
[0033] like Figures 1-7 As shown, a power supply cable 220 is inserted into the middle housing 200, and the power supply cable 220 passes through the middle housing 200 and connects to the light source base 410. Power is supplied to the light source module 400 inside the middle housing 200 through the power supply cable 220.
[0034] The advantages of implementing the multifaceted prism reflection imaging structure provided by this utility model compared with the prior art are as follows: The upper prism mechanism 100 and the lower prism mechanism 300 of this invention are used for mutual reflection and imaging. The object being observed is placed below the lower prism mechanism 300. Light from the object's surface is imaged from multiple directions by the reflecting prisms on the lower prism mechanism 300 and reflected onto the reflecting prisms of the upper prism mechanism 100. Finally, the light is reflected by the upper prism mechanism 100 to the camera for imaging. The light source module 400 provides illumination and supplementary lighting by emitting light. This is achieved by setting a first screw hole 111, a second screw hole 421, and a third screw hole. The positions of screw holes 210 and 320 allow for modular and detachable connections between the upper prism mechanism 100, the middle housing 200, the light source module, and the lower prism mechanism 300. This enables each structural component to be processed separately, reducing processing and replacement costs. The upper prism mechanism 100 is divided into an outer ring 110 and a first prism device 120, and the outer ring 110 and the first prism device 120 are fixedly connected via the first screw hole 111. This allows the outer ring 110 and the first prism device 120 to be used with different... Regarding the material, the first prism device 120 can be manufactured using non-metallic parts, avoiding the rounded corners that would result in excessive gaps at the joints of the reflecting prisms during metal part manufacturing, thus affecting imaging. By opening a second screw hole 421 on the side of the light source housing 420 and a third screw hole 210 on the side of the middle housing 200, a detachable connection can be achieved between the light source base 410, the light source housing 420, and the middle housing 200. The middle housing 200 can be made of non-metallic parts not used with the light source housing 420, thereby avoiding the middle housing... The rounded corners at the edges of the body 200 cause excessive gaps when assembling with other structures of the camera. This technical solution realizes a modular disassembly and assembly structure for the upper prism mechanism 100, the middle shell 200, the light source module, and the lower prism mechanism 300, allowing each part to be processed separately. Compared with integrated processing, the volume is smaller, the processing cost is lower, the assembly difficulty is lower, and different materials can be used to combine them. This avoids the large gaps at the splicing points between prisms caused by the rounded corners at the armor of metal parts, thereby improving the assembly accuracy.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
