Description

Technical Field

[0001] This utility model relates to the field of polarizing lens frames, and in particular to a polarizing lens frame for fine-tuning angles. Background Technology

[0002] Polarizers are important optical materials that can convert incident light of any polarization state into linearly polarized light, and they have wide applications in display technology, optical instruments, photography, and other fields. The main function of a polarizer frame is to provide a stable and precise mounting environment for the polarizer, ensuring its performance and accurate positioning within the optical system. Some frames allow for fine-tuning of the polarizer's angle to adapt to different optical requirements.

[0003] In the use of polarizing lens frames, the polarizer is installed on the frame and secured with a clamping ring. The angle of the polarizer can be adjusted using an adjusting wheel to ensure optimal performance. However, in existing adjustable polarizing lens frames, the adjustment wheel is used directly, which can easily lead to over-adjustment, affecting the stability of the adjusted lens. Furthermore, when tightening the screws after adjustment, the lack of pre-fixation can cause rotational misalignment, further impacting the performance. Utility Model Content

[0004] The main objective of this invention is to provide a polarizer frame for fine-tuning angles, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A polarizing lens frame for fine-tuning angle includes a frame body, an angle disc on the frame body, and an inner mounting sleeve inside the frame body. A clamping ring is connected inside the inner mounting sleeve, and an adjustment plate is connected to the inner mounting sleeve. A driven external tooth is provided on the adjustment plate, and a fine-tuning drive structure is installed on the frame body and connected to the driven external tooth.

[0007] Preferably, the angle plate is fixedly connected to the mounting inner sleeve, and the top of the frame body is provided with a threaded hole.

[0008] Preferably, a locking bolt is provided in the threaded hole on the frame body, and the end of the locking bolt abuts against the mounting inner sleeve, and the clamping ring is threadedly connected to the mounting inner sleeve.

[0009] Preferably, the fine-tuning drive structure includes a drive rod, a drive gear, a pressure plate, a rubber pad, a limit drive assembly, and a spring. The drive rod is fixedly connected to the drive gear and passes through the frame body. The pressure plate is installed at the end of the drive rod and is fixedly connected to the rubber pad. The drive gear meshes with the driven external gear on the adjustment plate.

[0010] Preferably, the limiting drive assembly is mounted on the drive rod, the spring is sleeved on the drive rod, and the spring is located between the limiting drive assembly and the frame body.

[0011] Preferably, the limiting drive assembly includes a mounting sleeve, a countersunk bolt, a connecting ring, a connecting rod, and a limiting bolt. The mounting sleeve is fixed to the drive rod by the countersunk bolt, the connecting ring is connected to the mounting sleeve by the connecting rod, and the limiting bolt is threaded onto the connecting ring.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The polarizer frame for angle fine adjustment has a driven external tooth on the adjustment plate, which works in conjunction with the fine adjustment drive structure. The driven external tooth and the rotation of the adjustment plate are adjusted by the driving gear in the fine adjustment drive structure. The gear ratio is used for speed reduction adjustment, which can effectively avoid excessive rotation of the adjustment plate and excessive angle adjustment, thus ensuring the effect of the polarizer. Through the setting of the limit drive component, spring, pressure plate and rubber pad, during adjustment, the limit drive component moves the drive rod, pressure plate and rubber pad to make room, and then rotates to adjust the angle. After adjustment, it is reset under the action of the spring. The rubber pad on the pressure plate presses on the adjustment plate to play a pre-fixing role, ensuring that the position does not deviate when it is fixed and locked later, ensuring the accurate use of the polarizer. The position of the limit drive component can be adjusted on the drive rod, which is convenient for adjusting the compression degree of the spring and has high adaptability.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a polarizing lens frame for fine-tuning angles includes a frame body 1, an angle disc 2 on the frame body 1, and an inner mounting sleeve 3 inside the frame body 1. A clamping ring 4 is connected inside the inner mounting sleeve 3, and an adjusting plate 5 is connected to the inner mounting sleeve 3. The adjusting plate 5 has a driven external tooth 6. A fine-tuning drive structure 7 is mounted on the frame body 1 and connected to the driven external tooth 6. The angle disc 2 is fixedly connected to the inner mounting sleeve 3, and a threaded hole is provided at the top of the frame body 1. A locking bolt 8 is installed in the threaded hole on the frame body 1, and the end of the locking bolt 8 abuts against the inner mounting sleeve 3. The clamping ring 4 is threadedly connected to the inner mounting sleeve 3.

[0020] When installing the polarizer, unscrew the clamping ring 4 from the mounting sleeve 3, place the polarizer into the mounting sleeve 3, and use the clamping ring 4 to clamp and fix it. Then, you can start using the polarizer. When it is necessary to adjust the angle of the polarizer, for coarse adjustment, after loosening the locking bolt 8, operate the fine-tuning drive structure 7 to move aside, and directly rotate the adjusting plate 5 through the driven external gear 6. The adjusting plate 5 rotates along with the mounting sleeve 3 and the polarizer. Use the angle dial 2 to determine the size of the adjustment angle. After adjustment, loosen the fine-tuning drive structure 7 to pre-fix the adjusting plate 5, and then fix it with the locking bolt 8. When it is necessary to fine-tune the polarizer, after loosening the locking bolt 8, use the fine-tuning drive structure 7 to drive the driven external gear 6 and the adjusting plate 5 to rotate. Use the deceleration adjustment method to fine-tune and ensure the adjustment accuracy. After adjustment, it can be used.

[0021] According to the above implementation scheme, the fine-tuning drive structure 7 includes a drive rod 701, a drive gear 702, a pressure plate 703, a rubber pad 704, a limiting drive assembly 705, and a spring 706. The drive rod 701 is fixedly connected to the drive gear 702 and passes through the frame body 1. The pressure plate 703 is installed at the end of the drive rod 701 and is fixedly connected to the rubber pad 704. The drive gear 702 meshes with the driven external gear 6 on the adjusting plate 5. The limiting drive assembly 705 is installed on the drive rod 701, and the spring 706 is sleeved on the drive rod 701, with the spring 706 located between the limiting drive assembly 705 and the frame body 1.

[0022] When driven by the fine-tuning drive structure 7, the drive rod 701 is first moved by the limit drive assembly 705. The drive rod 701 then moves the drive gear 702 and the pressure plate 703, causing the rubber pad 704 on the pressure plate 703 to move away from the adjusting plate 5. During this process, the limit drive assembly 705 also acts as a limit to prevent the drive gear 702 from disengaging from the driven external gear 6, while the spring 706 is compressed. After the rubber pad 704 moves away, the drive rod 701 and the drive gear 702 rotate by the limit drive assembly 705. The drive gear 702 then rotates the adjusting plate 5 through the driven external gear 6, thus achieving a speed reduction drive effect, which allows for fine-tuning of the polarizer angle. After adjustment, the limit drive assembly 705 is released. Under the action of the spring 706, the drive rod 701, the drive gear 702, and the pressure plate 703 return to their original positions. The rubber pad 704 contacts the adjusting plate 5 for pre-fixation, and finally, it is fixed by the locking bolt 8.

[0023] The limit drive assembly 705 includes a mounting sleeve 7051, a countersunk bolt 7052, a connecting ring 7053, a connecting rod 7054, and a limit bolt 7055. The mounting sleeve 7051 is fixed to the drive rod 701 by the countersunk bolt 7052. The connecting ring 7053 is connected to the mounting sleeve 7051 by the connecting rod 7054. The limit bolt 7055 is threadedly connected to the connecting ring 7053.

[0024] When using the limit drive assembly 705, the mounting sleeve 7051 moves the drive rod 701, while the connecting rod 7054 moves the connecting ring 7053 and the limit bolt 7055 until the limit bolt 7055 contacts the frame body 1. At this point, the rubber pad 704 has moved aside. Under the limiting action of the limit drive assembly 705, the drive gear 702 will not disengage from the driven external gear 6, ensuring the meshing connection effect. During drive, the mounting sleeve 7051 drives the drive rod 701 and the drive gear 702 to rotate, thereby making adjustments. When needed, the countersunk bolt 7052 can be loosened to change the position of the mounting sleeve 7051, thereby adjusting the compression degree of the spring 706 and changing the final pre-fixed clamping effect. After adjusting the position of the mounting sleeve 7051, the position of the limit bolt 7055 on the connecting ring 7053 needs to be rotated to ensure the limiting effect. The structure is simple and the performance is excellent.

[0025] It should be noted that a driven external gear 6 is provided on the adjusting plate 5, which works in conjunction with the fine-tuning drive structure 7. The driven external gear 6 and the adjusting plate 5 are rotated and adjusted by the driving gear 702 in the fine-tuning drive structure 7. The gear ratio is used for speed reduction adjustment, which can effectively avoid excessive rotation of the adjusting plate 5 and excessive angle adjustment, thus ensuring the effect of the polarizer. Through the setting of the limit drive component 705, spring 706, pressure plate 703 and rubber pad 704, during adjustment, the limit drive component 705 moves the drive rod 701, pressure plate 703 and rubber pad 704 to make room, and then rotates to adjust the angle. After adjustment, it is reset under the action of spring 706. The rubber pad 704 on the pressure plate 703 presses on the adjusting plate 5 to play a pre-fixing role, ensuring that the position does not deviate when it is fixed and locked later, thus ensuring the accurate use of the polarizer. The position of the limit drive component 705 can be adjusted on the drive rod 701, which facilitates the adjustment of the compression degree of spring 706, and has high adaptability.
