[0002] A light filter is an optical element that modulates light signals by selectively filtering specific wavelengths of light. It is widely used in photography, displays, scientific research, and other fields. Its core function is to alter the spectral composition or intensity of light through physical or chemical properties to meet different application requirements.

[0003] The patent titled "A Filter Holder for Optical Instrument Lenses" (patent application number: 201520578056.5) discloses a filter holder for optical instrument lenses. A sleeve is fitted onto the lens body, and a filter mounting platform is mounted on the sleeve. The mounting platform has a light-transmitting hole that communicates with the lens element and is located in the optical path of the lens body. Three slotted baffles are installed on the mounting platform to the left, below, and right of the light-transmitting hole. The filter is inserted into one of the three slotted baffles. This provides independent support for the installation of the filter on the optical instrument lens and allows for installation and removal as needed without damaging the optical instrument.

[0004] In the above case, although the filter can be disassembled and replaced using the screw inside the internal threaded hole B to facilitate the detection of different items by optical instruments, frequent disassembly and replacement of the filter can be time-consuming and laborious, and the screw can easily damage the filter, thus causing inconvenience to the use of the device. Therefore, it is necessary to propose a modular multi-group spliced ​​filter array structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular multi-group spliced ​​filter array structure to solve the problem mentioned in the background art that although the filter can be disassembled and replaced using the screw inside the internal threaded hole B so that optical instruments can detect different items, frequent disassembly and replacement of the filter can easily cause time-consuming and laborious problems, and the screw can easily damage the filter, thus bringing inconvenience to the use of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular multi-group splicing filter array structure, including a sleeve and a lens body, wherein an array component is provided at the bottom of the sleeve;

[0007] The array assembly includes a circular frame, a filter body, limiting bolts, and a rotating shaft;

[0008] The rotating shaft is rotatably connected to the inside of the sleeve, and the rotating shaft is fixedly connected to the inside of the center of the circular frame. The filter body is inserted into the inside of the circular frame, and the limiting bolt is threadedly connected to the inside of the circular frame.

[0009] Preferably, the number of filter bodies is four, and the four filter bodies are respectively an absorption filter, a dichroic filter, a hard film filter and a soft film filter.

[0010] Preferably, one end of the limiting bolt is fixedly connected to a second rubber pad, and the second rubber pad is in contact with the surface of the filter body.

[0011] Preferably, the bottom of the sleeve is provided with a limiting component, which includes a connecting block, a screw, a movable block and an arc-shaped limiting plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-3 The diagram shows a modular multi-group spliced ​​filter array structure, including a sleeve 1 and a lens body 2. The bottom of the sleeve 1 is provided with an array assembly, which includes a circular frame 3, filter bodies 4, limiting bolts 5, and a rotating shaft 6. The outside of the rotating shaft 6 is rotatably connected to the inside of the sleeve 1, and the outside of the rotating shaft 6 is fixedly connected to the inside of the center of the circular frame 3. The outside of the filter bodies 4 is inserted into the inside of the circular frame 3, and the outside of the limiting bolts 5 is threadedly connected to the inside of the circular frame 3. There are four filter bodies 4, which are respectively an absorption filter, a dichroic filter, a hard film filter, and a soft film filter. A light-transmitting hole 7 is opened inside the bottom end of the sleeve 1, and the lens body 2 is sleeved inside the sleeve 1. When optical instruments need to detect different items, a suitable filter body 4 can be selected. By rotating the circular frame 3, the position of the filter body 4 that matches the object to be detected corresponds to the position of the light-transmitting hole 7, so that the object can be detected quickly without frequent disassembly and replacement of the filter body 4, thus bringing convenience to the use of the device.

[0023] In addition, a second rubber pad is fixedly connected to one end of the limiting bolt 5, and the second rubber pad is in contact with the surface of the filter body 4. When it is necessary to fix the filter body 4, the limiting bolt 5 can be rotated, and the limiting bolt 5 will drive the second rubber pad to move, so that the second rubber pad is in contact with the surface of the filter body 4, thereby facilitating the fixing of the filter body 4.

[0024] Next, a limiting component is provided at the bottom of the sleeve 1. The limiting component includes a connecting block 8, a screw 9, a movable block 10, and an arc-shaped limiting plate 11. The top of the connecting block 8 is fixedly connected to the bottom of the sleeve 1, and the inside of the connecting block 8 is threadedly connected to the outside of the screw 9. The outside of one end of the screw 9 is rotatably connected to the inside of the movable block 10, and the side of the movable block 10 is fixedly connected to the side of the arc-shaped limiting plate 11. When the position of the filter body 4 matching the object being detected corresponds to the position of the light-transmitting hole 7, the screw 9 can be rotated. The screw 9 will drive the arc-shaped limiting plate 11 to move to one side of the circular frame 3 through the movable block 10, so that the arc-shaped limiting plate 11 limits and fixes the circular frame 3, which facilitates the limiting and fixing of the position of the filter body 4 and the light-transmitting hole 7, thereby bringing convenience to the switching of the filter body 4.

[0025] Finally, both sides of the sleeve 1 are provided with fixing components, which include fixing bolts 12 and first rubber pads 13. The outside of the fixing bolts 12 is connected to the internal threads of the side of the sleeve 1, and one end of the fixing bolts 12 is fixedly connected to one side of the first rubber pads 13. The other side of the first rubber pads 13 is in contact with the side of the lens body 2. When the lens body 2 is placed inside the sleeve 1, the fixing bolts 12 can be rotated, which will cause the first rubber pads 13 to move, so that the first rubber pads 13 are in contact with the side of the lens body 2, thereby facilitating the fixing of the lens body 2 inside the sleeve 1.

[0026] Working principle: The lens body 2 can be placed inside the sleeve 1. Rotating the fixing bolt 12 will cause the fixing bolt 12 to move the first rubber pad 13, so that the first rubber pad 13 contacts the side of the lens body 2, thus facilitating the fixing of the lens body 2 inside the sleeve 1. When the optical instrument needs to detect different items, a suitable filter body 4 can be selected. By rotating the circular frame 3, the position of the filter body 4 matching the object to be detected corresponds to the position of the light-transmitting hole 7, so that the object can be quickly detected without frequent disassembly and replacement of the filter body 4, thus bringing convenience to the use of the device. When the position of the filter body 4 matching the object to be detected corresponds to the position of the light-transmitting hole 7, the screw 9 can be rotated. The screw 9 will drive the arc-shaped limiting plate 11 to one side of the circular frame 3 through the movable block 10, so that the arc-shaped limiting plate 11 limits and fixes the circular frame 3, which facilitates the positioning and fixing of the filter body 4 and the light-transmitting hole 7, thus bringing convenience to the switching of the filter body 4.
