[0003] The existing patent CN215575873U discloses a lens, including a lens barrel and an optical system arranged in the lens barrel, two cutting planes are arranged opposite to each other on the outer side of the lens barrel, and also includes a light blocking structure whose inner diameter is adapted to the outer diameter of the lens barrel, and the light blocking structure is located at the image side end and / or object side end of the lens barrel.

[0004] In order to solve the problem of motor stray light appearing in the short and long directions of the lens, this patent can select the main light blocking structure as the rear light blocking plate, front / rear blocking protrusions and front pressure ring according to the lens barrel structure and the actual location where the stray light is generated, thereby providing different light blocking solutions to meet the needs of periscope telephoto lenses with different structures.

[0005] However, in actual use, there are still some shortcomings, such as: the traditional optical lens installation process usually requires professional tools and a long time. When replacing the lens, the user needs to remove the original lens first, then align the camera interface, adjust the lens position, and finally fix the screws. This process is not only cumbersome, but also easy to cause damage to the lens or camera interface for non-professionals.

[0006] Therefore, the utility model provides an optical lens quick-change connector. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1 - Figure 4As shown, this embodiment provides a technical solution: an optical lens quick-transfer connector, comprising a lens 3, a connecting component 1 is provided at one end of the lens 3, and a positioning component 2 is provided inside the connecting component 1;

[0032] The connecting assembly 1 includes a mounting block 11, and driven positioning rings 12 are fixedly connected to the inner wall of the mounting block 11 at both ends. A mounting ring 13 is rotatably connected to the inner wall of the mounting block 11. A limited sliding groove 14 is provided on the side of the mounting ring 13 close to the mounting block 11. The outer side of the driven positioning ring 12 is slidably connected to the limited sliding groove 14. An active positioning ring 15 is movably connected to the end of the mounting block 11 away from the mounting ring 13. The two sides of the lens 3 are respectively engaged with the inner part of the mounting ring 13 and the active positioning ring 15. The driven positioning ring 12 is fixedly connected to the inner wall of the mounting block 11 at both ends. This arrangement ensures the precise alignment of the lens during installation or removal. The mounting ring 13 in the mounting block 11 is connected to the mounting block 11 through a rotating mechanism. This rotating connection design makes The lens can be fine-tuned without disassembling the entire device, which improves the convenience and accuracy of adjustment. The limit slide groove 14 is engaged with the outer side of the driven positioning ring 12. This sliding connection design allows the mounting ring 13 to slide within a certain range, increasing the adjustment flexibility of the device. The active positioning ring 15 at the far end of the mounting block 11 is connected to the mounting block 11 through a movable connection mechanism. This design enables the active positioning ring 15 to adjust its position when necessary to adapt to lenses of different thicknesses or sizes, thereby achieving a more universal interface design. Finally, the two sides of the lens 3 are respectively engaged with the inside of the mounting ring 13 and the active positioning ring 15. This engagement mechanism ensures the stability and safety of the lens in use and reduces the looseness of the lens.

[0033] To avoid the lens from shifting after installation, Figure 1 , Figure 3 and Figure 4As shown: In this solution, the positioning component 2 includes a rotating groove 21, the inner wall of the rotating groove 21 is rotatably connected to a limited rotating circle 22, the end of the limited rotating circle 22 away from the mounting block 11 is fixedly connected to an operating block 23, the end of the operating block 23 close to the driven positioning circle 12 is rotatably connected to the mounting block 11, the inner wall of the operating block 23 is threadedly connected to a threaded circle 24, the inside of the threaded circle 24 is fixedly connected to the active positioning circle 15, the design of the rotating groove 21 allows the limited rotating circle 22 to rotate freely inside it, so that the operator can adjust more flexibly and realize fast and accurate positioning, the design of the operating block 23 allows the user to simply The operating block 23 can be rotated without complicated disassembly and assembly of the entire device. One end of the operating block 23 is connected to the mounting block 11 through a rotating mechanism, which makes the user feel smoother when adjusting and reduces the error in operation. The inner wall of the operating block 23 is threadedly connected with a threaded ring 24. This threaded connection method not only ensures the close connection between the components, but also provides an adjustable interface. When the active positioning ring 15 is disconnected from the operating block 23, the lens can be placed on the active positioning ring 15 and then rotated to meet the installation requirements of lenses of different specifications. This design greatly improves the applicability and flexibility of the adapter.

[0034] Working principle:

[0035] like Figure 1 - Figure 4 As shown:

[0036] When in use: first, gently place the lens 3 on the active positioning ring 15 to ensure that the lens is accurately positioned to avoid deviation in subsequent operations. Next, the operator needs to move the operating block 23 toward it through the threaded ring 24 on the active positioning ring 15. When the operating block 23 reaches the appropriate position, the operator needs to rotate the operating block. During this process, the limiting rotating circle 22 on the operating block will rotate with the mounting block 11. This is to ensure that the connection between the threaded ring 24 and the operating block 23 is more secure. As the operating block rotates, the active positioning ring 15 will move toward the inside of the mounting block 11. After the active positioning ring moves into place, the operator needs to rotate the mounting ring 13. At this time, the limiting groove 14 on the mounting ring will slide on the driven positioning ring 12 on the mounting block 11. After the limiting groove 14 slides to the appropriate position, the operator needs to disengage it from the deeper limiting grooves on both sides and rotate it 45°. Finally, the operator continues to rotate the operating block 23 to move it toward the mounting ring 13. During this process, both sides of the lens 3 will engage with the mounting ring 13 and the active positioning ring 15. When the lens is fully embedded in place and both sides are tightly engaged with the mounting ring and the active positioning ring, the installation is complete.
