[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] In practical use, most traditional multi-lens combination optical lenses with clear imaging may not be easy to replace the lenses inside the optical lens. When the optical lens is damaged or needs to be used under special lighting conditions, traditional multi-lens combination optical lenses may not be able to meet the user's needs immediately, causing the user to need to carry a variety of different multi-lens combination optical lenses, which is very troublesome and greatly increases the cost of use.

[0023] In view of this, the present invention provides a multi-lens combination optical lens with clear imaging, which solves the problem that in actual use, most traditional multi-lens combination optical lenses with clear imaging may not be easy to replace the lenses inside the optical lens. When the optical lens is damaged or needs to be used under special lighting conditions, traditional multi-lens combination optical lenses may not be able to meet the user's needs immediately, causing the user to need to carry a variety of different multi-lens combination optical lenses, which is very troublesome and greatly increases the cost of use.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] Example 1: By Figure 1-5 As can be seen, a multi-lens optical lens with clear imaging includes a mounting base 1, of which four mounting bases 1 are provided. The four mounting bases 1 are respectively provided with a first lens 12, a second lens 13, a third lens 14, and a fourth lens 15. A limit rod 16 is inserted into the inner wall of the mounting base 1. The multi-lens optical lens with clear imaging also includes a fixing device 2, an adjusting device 3, and a protective device 5. The fixing device 2 is located on one side of the mounting base 1; the adjusting device 3 is located inside the mounting base 1; and the protective device 5 is located on the side of the first lens 12 away from the second lens 13. The first lens 12, the second lens 13, the third lens 14, and the fourth lens 15 are connected sequentially by multiple fixing devices 2. The first lens 12, the second lens 13, the third lens 14, and the fourth lens 15 are adjusted by multiple adjusting devices 3 respectively. The protective device 5 protects the first lens 12.

[0026] In the specific implementation process, it is worth noting that the mounting base 1 consists of two identical parts, arranged symmetrically along an axis, connected by four limiting rods 16. The material of the mounting base 1 can be selected according to actual needs; for example, it can be made of metal, such as aluminum alloy. The limiting rods 16 serve to fix the mounting base 1, and can also be made of metal to improve the service life of the limiting rods 16. It is understood that the number, type, material, and spacing of the lenses inside the multi-lens combination optical lens (first lens 12, second lens 13, third lens 14, and fourth lens 15) for clear imaging can be determined according to actual imaging requirements and system functions. The internal space of the lens is reasonably selected based on manufacturing costs, and sealing gaskets can be added at appropriate positions between various devices to prevent dust, moisture and other impurities from entering the lens and affecting image quality. Users can connect the first lens 12, the second lens 13, the third lens 14 and the fourth lens 15 in sequence through multiple fixing devices 2 to achieve quick installation, and adjust the first lens 12, the second lens 13, the third lens 14 and the fourth lens 15 respectively through multiple adjustment devices 3 to achieve zoom according to actual conditions. The protective device 5 protects the first lens 12 and improves the service life of the first lens 12.

[0027] Furthermore, a protective ring 4 is provided on one side of the mounting base 1, and a base 6 is provided on the other side of the mounting base 1. The fixing device 2 includes a connecting ring 21, a fixing block 22, a connecting seat 23, a spring 24, a fixing ring 25, and a fixing groove 26. A connecting ring 21 is provided for each mounting base 1, and there is one more connecting ring 21 than the number of mounting bases 1. One connecting ring 21 is fixedly connected to the outer wall of the protective ring 4 near the side of the mounting base 1, and the remaining connecting rings 21 are fixedly connected to the outer wall of the mounting base 1. A fixing block 22 is provided for each connecting ring 21, and the remaining blocks are fixedly connected to the outer wall of the connecting ring 21. A connecting seat 23 is provided for each connecting ring 21. One connecting seat 23 is fixedly connected to the outer wall of the base 6 near the side of the mounting base 1, and the remaining connecting seats 23 are fixedly connected to the outer wall of the mounting base 1 away from the connecting ring. One side of the connecting ring 21, and the inner wall of each connecting ring 21 is attached to the side wall of the fixing block 22; the spring 24 is provided for each connecting seat 23, and is respectively provided inside each connecting seat 23, and is fixedly connected to one side of the inner wall of the connecting seat 23, and the inner wall is sleeved on the outer wall of the connecting ring 21; the fixing ring 25 is provided for each connecting seat 23, and is respectively provided inside each connecting seat 23, and is fixedly connected to the end of the spring 24 away from the inner wall of the connecting seat 23; the fixing groove 26 is provided for each fixing ring 25, and is opened on the outer wall of the fixing ring 25, and the inner wall is engaged with the side of the outer wall of the fixing block 22 away from the connecting seat 23; wherein, through the fixing block 22 on the outer wall of the connecting ring 21, the two mounting seats 1 are connected together by the cooperation of the connecting seat 23, the spring 24, the fixing ring 25, and the fixing groove 26;

[0028] In the specific implementation process, it is worth noting that the protective ring 4 is frustum-shaped, and other shapes or styles of protective rings 4 can be selected according to actual needs to achieve the protective function. The base 6 is annular, and appropriate bases 6 and fixing clips 61 are selected according to different cameras and optical equipment. The connecting ring 21 is annular, and each mounting base 1 is provided with one more connecting ring than the number of mounting bases 1. The connecting ring 21 can be made of metal, and its outer diameter is smaller than the outer diameter of the mounting base 1. It can be fixedly connected to the protective ring 4 and the mounting base 1 by welding or high-strength adhesive. The fixing block 22 is rectangular in shape with beveled sides to facilitate the use of the fixing groove 26. The fixing block 22 is made of the same metal material as the connecting ring 21 and plays a role in positioning and connection during the connection process. The connecting base 23 is annular in shape and has internal machining. It has an annular groove for placing the spring 24 and the fixing ring 25. Four notches are machined on one side of the outer wall. The spring 24 is made of high-strength stainless steel, and its elastic coefficient can be selected according to the actual situation to ensure sufficient elastic force during the connection process. The fixing ring 25 is annular, and its surface has four fixing grooves 26 that match the fixing block 22. When connected, the fixing block 22 is embedded in the fixing groove 26, and the elastic force of the spring 24 makes the fixing block 22 and the fixing groove 26 tightly locked. The user connects the two mounting seats 1 together by using the fixing block 22 on the outer wall of the connecting ring 21, the connecting seat 23, the spring 24, the fixing ring 25, and the fixing groove 26. When it is necessary to replace one of the lenses, it can be quickly disassembled and the lens can be easily installed on the optical lens, realizing the convenience of using a multi-lens combination optical lens that improves image clarity.

[0029] Furthermore, the adjustment device 3 includes an adjustment ring 31, an adjustment seat 32, and an anti-slip ring 33. The adjustment ring 31 is provided for each mounting seat 1 and is located inside the mounting seat 1. The adjustment seat 32 is provided for each adjustment ring 31 and is threadedly connected to the inner wall of the adjustment ring 31. The inner wall is sleeved on the outer wall of the limiting rod 16, and the bottom is respectively inserted into the outer wall groove of the first lens 12, the second lens 13, the third lens 14, and the fourth lens 15. The anti-slip ring 33 is provided for each adjustment seat 32 and is fixedly connected to both sides of the outer wall of the adjustment seat 32. The inner wall is respectively attached to the outer wall of the first lens 12, the second lens 13, the third lens 14, and the fourth lens 15. Through the cooperation of the adjustment ring 31, the adjustment seat 32, and the anti-slip ring 33, the first lens 12, the second lens 13, the third lens 14, and the fourth lens 15 can all be adjusted.

[0030] In the specific implementation process, it is worth noting that the outer wall of the adjustment ring 31 is provided with anti-slip texture and the inner wall is provided with threads. Its material can also be metal. The adjustment ring 31 can make the adjustment seat 32 move along the limit rod 16 through the threads. The cross section of the adjustment seat 32 is 'T' shaped, and the bottom protrusion plays a role in fixing the lens. The anti-slip ring 33 is generally made of rubber or silicone and plays a role in fixing the lens and the adjustment seat 32, increasing the friction, eliminating the gap between the two, and preventing the lens from shaking. Through the cooperation of the adjustment ring 31, the adjustment seat 32 and the anti-slip ring 33, the user can adjust the first lens 12, the second lens 13, the third lens 14 and the fourth lens 15, realizing the use of a multi-lens combination optical lens that improves image clarity.

[0031] Specifically, when a lens is damaged and needs to be replaced, the user holds the connecting seat 23 behind the adjustment seat 32 containing the damaged lens with one hand, and rotates the connecting seat 23 in front of the adjustment seat 32 containing the damaged lens with the other hand. The rotation of the front connecting seat 23 causes the adjustment seat 32 containing the damaged lens to rotate, which in turn causes the connecting ring 21 fixed to its side wall to rotate. The connecting ring 21 that matches the damaged lens slides out of the fixing groove 26 on the fixing ring 25 in the connecting seat 23 behind the adjustment seat 32 containing the damaged lens through its inclined surface. After sliding out, the fixing block 22 on the outer wall of the connecting ring 21 that matches the damaged lens presses against the fixing ring 25 behind it. The fixing ring 25 behind it compresses the spring 24 behind it. At the same time, through the above-mentioned rotation action, the fixing block 22 on the outer wall of the connecting ring 21 that matches the damaged lens passes through the connecting seat 23 behind it. The four notches on the side wall separate the connecting seat 23 at the rear. At this time, the multi-lens optical lens is divided into two parts. Then, remove the four limiting rods 16 fixed on the mounting seat 1 where the damaged lens is located, so that the mounting seat 1 can be disassembled. By rotating the adjusting seat 32, the adjusting seat 32 is separated from the adjusting ring 31. After separation, the user can remove the damaged lens by hand and replace it with a new lens. After replacement, the user can reverse the above actions to install the new lens into the multi-lens optical lens. It should be understood that the above disassembly and installation process is only one method in actual application. Any of the first lens 12, the second lens 13, the third lens 14 and the fourth lens 15, or any newly added lens, can be disassembled or installed in the above way, provided that the environment for disassembly or installation is as clean and tidy as possible to prevent contamination.

[0032] Example 2: From Figure 1-5It can be seen that the outer walls of the adjusting ring 31 are fixedly connected to both sides of the limiting ring 31, and the outer walls of the two limiting rings 311 are slidably connected with annular grooves 11. The two annular grooves 11 are respectively opened on the opposite side of the outer walls of the two mounting seats 1.

[0033] In the specific implementation process, it is worth noting that the limiting ring 311 plays a limiting and fixing role on the adjusting ring 31. Through the cooperation of the limiting ring 311 and the annular groove 11, it can rotate inside the mounting base 1, thereby improving the working stability of the multi-lens combination optical lens with clear imaging.

[0034] Furthermore, the protective device 5 includes a protective plate 51 and a fixing seat 52. The protective plate 51 is rotatably connected to the outer wall of the protective ring 4 away from the connecting ring 21 by a pin. The fixing seat 52 is fixedly connected to the top of the protective ring 4, and its inner wall is engaged with the top protrusion of the protective plate 51. The first lens 12 is protected by the cooperation of the protective plate 51 and the fixing seat 52.

[0035] In the specific implementation process, it is worth noting that the protective plate 51 is circular and opaque. When not in use, it protects the lens inside the mounting base 1 from damage caused by external forces, environmental factors, process factors, and usage factors. The top of the protective plate 51 is provided with a spherical protrusion, and a spherical groove is provided on the side wall of the fixing base 52. Through the cooperation of the spherical protrusion and the spherical groove, the protective plate 51 is fixed to one side of the protective ring 4, thereby improving the service life of the multi-lens combination optical lens with clear imaging.

[0036] Furthermore, a fixing clip 61 is fixedly connected to the outer wall of the base 6 on the side away from the connecting seat 23;

[0037] In the specific implementation process, it is worth noting that the fixing card 61 is in the shape of a ring and the cross section is convex, which makes it easy to connect with an external camera and play a role in connection and fixation, thereby realizing the ease of use of the multi-lens combination optical lens that further improves the image clarity.

[0038] Specifically, when the user needs to use the multi-lens combination optical lens with clear imaging, the user can gently pry open the protective plate 51 by hand. The protective plate 51 will cause the protrusion on its top to leave the spherical groove on the side wall of the fixing seat 52. At this time, the protective plate 51 will flip under the protective ring 4 through the pin, and the multi-lens combination optical lens with clear imaging can be used. When the user does not need to use the multi-lens combination optical lens with clear imaging, the above operation can be reversed to make the protective plate 51 re-close the protective ring 4.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
