Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a low-distortion wide-angle optical lens assembly. Background Technology

[0002] In the installation and application of low-distortion wide-angle optical lens assemblies, existing technologies mostly use threaded connections to connect the lens body and the lens mount. However, threaded connections are prone to thread wear during long-term installation and disassembly operations. Prolonged thread wear not only significantly reduces the connection stability between the lens body and the lens mount, affecting the normal use of the optical lens assembly, but also increases maintenance costs and the frequency of component replacement, reducing the overall lifespan and user experience of the product. This may fail to meet users' needs for stable and convenient installation and long-term reliable use of the lens assembly. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art and to propose a low-distortion wide-angle optical lens group.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The low-distortion wide-angle optical lens assembly includes a lens body detachably attached to a lens mount, and also includes:

[0006] Mounting base, fixedly connected to lens mount, wherein multiple sets of mounting rods are fixedly connected in the mounting base;

[0007] The ferrule is fixedly connected to the lens body, and the ferrule has multiple sets of mounting holes that match the mounting rod;

[0008] The mounting rod has a locking hole, and a locking rod is slidably connected in the locking sleeve. A first magnet is fixedly connected to the locking rod.

[0009] The rotating plate is rotatably connected to the ferrule.

[0010] A second magnet is fixedly connected to the rotating plate, and the first magnet and the second magnet repel each other.

[0011] When the rotating plate causes the second magnet to face the first magnet, the magnetic repulsion pushes the locking rod into the locking hole for positioning and fixation.

[0012] Preferably, the sleeve has a groove, and a slider is slidably connected in the groove, the slider being fixedly connected to the side wall of the clamp rod.

[0013] Preferably, a limiting rod is fixedly connected in the card hole, and a limiting hole is formed on the card rod. The limiting rod matches the limiting hole. When the card rod slides into the card hole, the limiting rod slides into the limiting hole for limiting.

[0014] Preferably, a third magnet is fixedly connected to the mounting base, and a fourth magnet is fixedly connected to the rotating plate, wherein the third magnet and the fourth magnet are attracted to each other.

[0015] Preferably, the thickness ratio of the first magnet to the second magnet is 1:2.

[0016] Furthermore, a clearance groove is provided on the limiting hole, and a clearance arc surface is provided on the limiting rod.

[0017] Compared with the prior art, this utility model provides a low-distortion wide-angle optical lens group, which has the following beneficial effects:

[0018] 1. This utility model uses a combination of a rotating plate, a magnet, and a locking rod structure to achieve the connection and fixation of the lens body and the lens mount through magnetic repulsion and locking. It no longer uses the traditional threaded installation method, avoiding the problems of unstable connection and high maintenance costs caused by thread wear, and effectively improving the service life and reliability of the lens assembly.

[0019] 2. When the lens body needs to be replaced, the rotating plate is reversed to separate the fourth magnet from the third magnet, and the magnetic repulsion between the second magnet and the first magnet is released simultaneously. It can be quickly disassembled by pulling it outward, without the need for cumbersome screw-tightening operations, which facilitates later maintenance and component replacement.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1:

[0030] Reference Figures 1-6 The low-distortion wide-angle optical lens assembly includes a lens body 2 detachably connected to a lens mount 1, and also includes:

[0031] Mounting base 3 is fixedly connected to lens mount 1, and multiple sets of mounting rods 4 are fixedly connected in mounting base 3;

[0032] The ferrule 6 is fixedly connected to the lens body 2, and the ferrule 6 has multiple sets of mounting holes 602 that match the mounting rod 4;

[0033] The mounting rod 4 has a locking hole 402, and the locking rod 8 is slidably connected in the sleeve 6. The first magnet 7 is fixedly connected to the locking rod 8.

[0034] Rotating plate 5 is rotatably connected to ferrule 6;

[0035] A second magnet 502 is fixedly connected to the rotating plate 5, and the first magnet 7 and the second magnet 502 repel each other;

[0036] When the rotating plate 5 drives the second magnet 502 to face the first magnet 7, the magnetic repulsion pushes the locking rod 8 into the locking hole 402 for limiting and fixing.

[0037] Reference Figures 1-5In use, the operator aligns the mounting rod 4 with the mounting hole 602 on the sleeve 6 and presses the lens body 2 onto the mounting base 3. After the sleeve 6 is inserted into the mounting base 3, the operator rotates the rotating plate 5. The rotation of the rotating plate 5 will cause the second magnet 502, which is fixedly connected to it, to rotate synchronously. When the second magnet 502 rotates to a certain angle, the second magnet 502 will be opposite to the first magnet 7. Since the second magnet 502 and the first magnet 7 are magnetically repulsive, the first magnet 7 will push the locking rod 8 to slide to the right under the action of magnetic repulsion. At this time, the locking rod 8 will slide into the locking hole 402. When the locking rod 8 slides to its maximum limit, the limiting and fixing of the lens body 2 is completed.

[0038] The sleeve 6 has a groove 601, and a slider 801 is slidably connected in the groove 601. The slider 801 is fixedly connected to the side wall of the lever 8.

[0039] A limiting rod 401 is fixedly connected in the locking hole 402. A limiting hole 802 is opened on the locking rod 8. The limiting rod 401 matches the limiting hole 802. When the locking rod 8 slides into the locking hole 402, the limiting rod 401 slides into the limiting hole 802 for limiting.

[0040] Reference Figure 2 , Figure 3 and Figure 5 A third magnet 301 is fixedly connected to the mounting base 3, and a fourth magnet 501 is fixedly connected to the rotating plate 5. The third magnet 301 and the fourth magnet 501 attract each other.

[0041] Reference Figure 2 , Figure 3 When in use, when the operator rotates the rotating plate 5, it will simultaneously drive the fourth magnet 501 to rotate. When the second magnet 502 rotates to be opposite to the first magnet 7, the fourth magnet 501 rotates to be opposite to the third magnet 301. At this time, the fourth magnet 501 will attract the third magnet 301. Through the attraction between the fourth magnet 501 and the third magnet 301, the installation stability of the lens body 2 is further guaranteed.

[0042] Reference Figure 2 , Figure 3 When the lens body 2 needs to be replaced, the staff reverses the rotating plate 5 to separate the fourth magnet 501 and the third magnet 301, thus completing the disassembly.

[0043] During the separation of the fourth magnet 501 and the third magnet 301, the second magnet 502 will rotate synchronously. After rotating to a certain angle, the second magnet 502 will no longer be opposite to the first magnet 7. At this time, the magnetic repulsion force of the second magnet 502 on the first magnet 7 is small. The staff can pull the lens body 2 outward to remove the ferrule 6 from the mounting base 3.

[0044] The thickness ratio of the first magnet 7 and the second magnet 502 is 1:2.

[0045] Reference Figure 6 In specific implementation, a clearance groove 8021 is provided on the limiting hole 802, and a clearance arc surface 4011 is provided on the limiting rod 401.

[0046] By using the clearance groove 8021 on the limiting hole 802 and the clearance arc surface 4011 on the limiting rod 401, the limiting rod 401 can be stably inserted into the limiting hole 802.

[0047] Example 2:

[0048] Reference Figure 7 The low-distortion wide-angle optical lens group is basically the same as that in Embodiment 1. Furthermore, an elastic pull rope 9 is fixedly connected to the slider 801, and the end of the elastic pull rope 9 away from the slider 801 is fixedly connected to the inner side wall of the slide groove 601.

[0049] When the operator rotates the rotating plate 5 so that the second magnet 502 is no longer opposite the first magnet 7, the elastic pull rope 9 on the slider 801 can pull the slider 801 to quickly reset, thereby quickly pulling the lever 8 out of the locking hole 402.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
