Description

Technical Field

[0001] This utility model relates to the field of optical lens device technology, and in particular to an optical lens assembly with image stabilization function. Background Technology

[0002] In the field of photography and videography, optical lenses often need to be paired with filters to achieve different shooting effects, such as polarizing filters to reduce reflections and graduated neutral density filters to balance exposure.

[0003] When changing filters on traditional optical lenses, the old filter must be unscrewed and the new filter installed. This process is cumbersome and time-consuming, especially in scenarios where quick filter switching is required to capture fleeting moments (such as news shooting or sports event shooting). This can easily lead to missing the best shooting opportunity and affect shooting efficiency and results.

[0004] While lenses with image stabilization improve shooting stability, the inconvenience of changing filters still limits the user experience.

[0005] Therefore, an optical lens assembly with image stabilization is provided to address the aforementioned problems. Utility Model Content

[0026] 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.

[0027] Example:

[0028] Reference Figure 1-6 An optical lens assembly with image stabilization includes an image-stabilized lens body 1, and further includes: an outer ring 2, threadedly connected to the light-inlet end of the image-stabilized lens body 1; multiple sets of mounting rings 504, all rotatably connected to the outer ring 2, each mounting ring 504 having an external thread; a filter 4, threadedly connected to the mounting rings 504, which, by rotating the mounting rings 504, allows the filter 4 to cover the light-inlet end of the image-stabilized lens body 1; multiple sets of mounting blocks 501 are fixedly connected in a ring at equal intervals on the outer ring 2, each mounting block 501 having a slot into which a rod 502 is inserted; and mounting rings 504... 4. A rotatable connection is made to the insert rod 502. The insert rod 502 has a groove, and a rotating rod 503 is rotatably connected in the groove. The mounting ring 504 is fixedly connected to the rotating rod 503. A connecting shaft is fixedly connected to one end of the rotating rod 503 located in the groove. The connecting shaft is rotatably connected in the groove and has rotational damping. The outer ring 2 has an external thread, and a UV mirror 3 is threaded onto the external thread. By rotating the mounting ring 504, the filter 4 can be fitted onto the UV mirror 3. A limit bolt 6 is threaded onto the mounting block 501. The limit bolt 6 is used to fix the insert rod 502.

[0029] Tighten the external ring 2 onto the light-inlet end of the image-stabilized lens body 1 using the screw thread to ensure a secure and loose connection.

[0030] Insert the insert rod 502 into the slot of the mounting block 501, adjust its position, and tighten the limit bolt 6 to fix the insert rod 502; assemble the rotating rod 503 into the groove of the insert rod 502, realize the rotational connection by using the connecting shaft, and make the rotating rod 503 rotate smoothly and stay stably by the set rotational damping; finally, fix the mounting ring 504 on the rotating rod 503 to complete the assembly of the mounting ring 504 assembly and the outer ring 2.

[0031] According to the shooting requirements, first screw the UV filter 3 onto the external thread of the outer ring 2 to provide basic protection and filter out ultraviolet rays; then screw the filters 4 with different functions onto the mounting rings 504 respectively to complete the overall assembly of the components.

[0032] When shooting, if you need to switch the filter 4 effect, you do not need to remove the original filter 4. Observe the type of filter 4 currently installed and the required filter 4, and determine the corresponding installation ring 504.

[0033] Manually rotate the target mounting ring 504. With the help of the rotation of the rotating rod 503 in the groove of the insertion rod 502 and the rotation of the mounting ring 504 itself, the filter 4 on the mounting ring 504 is gradually covered onto the light-inlet end of the image-stabilized lens body 1 or the UV filter 3 until the light-inlet area is completely covered. The position of the mounting ring 504 is kept stable by the rotation damping.

[0034] If you need to switch back to another filter 4 or remove the current filter 4, simply rotate the corresponding mounting ring 504 in the opposite direction to rotate the filter 4 out of the light-in-the-end coverage area, quickly complete the filter 4 switch, and continue shooting.

[0035] For example, when shooting landscapes outdoors, first protect the lens and filter ultraviolet rays with UV filter 3; if you need to enhance the color saturation of the image and eliminate reflections on the water surface, rotate the mounting ring 504 with the polarizing filter to attach the polarizing filter to UV filter 3; if the light becomes stronger later, you need to use an ND filter, rotate the corresponding mounting ring 504 to switch the ND filter to the light-gathering end. The whole process does not require removing filter 4, and you can quickly switch to capture the best shooting opportunity.

[0036] The filter 4 can be quickly fitted and removed by rotating the mounting ring 504, which greatly shortens the replacement time of the filter 4 compared to the traditional screw-on replacement method.

[0037] The mounting block 501, the insertion rod 502, the rotating rod 503 and the limiting bolt 6 work together to ensure the stable rotational connection of the mounting ring 504. The rotational damping design makes the position of the filter 4 stable after switching, avoiding the effect of vibration displacement during shooting; the UV filter 3 is threadedly connected to the external ring 2.

[0038] This invention allows the filter 4 to be mounted on the mounting ring 504 via an external ring 2 with a mounting ring 504. When taking photos, simply rotate the mounting ring 504 to attach the required filter 4 to the light-inlet end of the image-stabilized lens, reducing the time required to change the filter 4 and facilitating shooting.

[0039] 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.
