Description

Technical Field

[0001] This utility model relates to a camera lens protection mechanism, specifically a lens protection mechanism for an action camera, and belongs to the field of camera accessory technology. Background Technology

[0002] Action cameras, as core imaging devices for outdoor and sports scenarios, are characterized by their compact size, lightweight design, and excellent impact resistance. They not only capture dynamic footage of sports from a first-person perspective but can also be mounted on helmets, handlebars, paddleboards, and other carriers via external brackets, enabling multi-angle, immersive image recording. This provides crucial support for users to preserve moments of action, analyze movements, or create outdoor vlogs. The lens, as the core optical component of an action camera, directly affects image clarity and color reproduction through its surface coating. Damage to the lens can lead to scratches, glare, color distortion, and in severe cases, even prevent normal shooting. Therefore, most action cameras currently use transparent protective plates as the lens's "first line of defense," physically shielding it from contaminants and impacts such as gravel, sand, salt spray, snow particles, and sweat.

[0003] However, most entry-level and mid-range action cameras use 3M adhesive or UV-cured adhesive to fix the transparent protective plate. The adhesive surface is mostly the annular area on the front of the lens. When the protective plate needs to be replaced due to scratches, yellowing, or damage after long-term use, users need to use tools such as utility knives and pry tools to slowly peel off the residual adhesive. This is not only time-consuming, but the adhesive is also easy to remain on the lens coating surface. If the operation is not done properly during the subsequent cleaning process, it is very easy to scratch the coating layer and cause irreversible lens damage, resulting in poor operation convenience and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a lens protection mechanism for action cameras to solve the above-mentioned problems. By optimizing the fixing and disassembly structure of the transparent protective plate, it solves the problems of inconvenience and time-consuming replacement of existing adhesive transparent protective plates, realizes rapid replacement of transparent protective plates, shortens replacement time, improves replacement efficiency, and avoids damage to the lens during the replacement process, thereby improving operational safety.

[0005] The present utility model achieves the above object through the following technical solutions. A lens protection mechanism for a sports camera includes a sports camera body. A connecting seat is fixedly connected to the sports camera body. A transparent protection plate is clamped at one end of the connecting seat. A pressing sleeve is clamped at one end of the connecting seat. The pressing sleeve abuts against the transparent protection plate. A fixing structure is provided on the pressing sleeve. The fixing structure includes a pressing ring and a first hook block. A pressing ring is slidably connected to the pressing sleeve. A plurality of first hook blocks are fixedly connected to one side of the pressing ring. A rotating ring is rotatably connected to the connecting seat. A plurality of second hook blocks corresponding to the first hook blocks one by one are fixedly connected to the outer side of the rotating ring. The first hook block abuts against the adjacent second hook block. A plurality of connecting blocks corresponding to the second hook blocks one by one are fixedly connected to the sports camera body. A first spring is fixedly connected between the second hook block and the adjacent connecting block. A pressing structure is provided on the pressing ring.

[0006] Preferably, the cross-section of one end of the first hook block is in a trapezoidal structure, and the cross-section of one end of the second hook block is in a trapezoidal structure.

[0007] Preferably, the plurality of first hook blocks are distributed in a circumferential array about the center of the pressing ring, and the plurality of second hook blocks are distributed in a circumferential array about the middle of the rotating ring.

[0008] Preferably, a sealing ring is clamped on the pressing sleeve, and the sealing ring abuts against the transparent protection plate.

[0009] Preferably, the end of the longitudinal section of the pressing sleeve is in an L-shaped structure, and one side of the transparent protection plate extends to the outside of the connecting seat.

[0010] Preferably, the pressing structure includes a pressing shaft and a connecting cylinder. A plurality of pressing shafts are fixedly connected to the pressing ring. The pressing shaft is slidably connected between the pressing sleeve. A plurality of connecting cylinders corresponding to the pressing shafts one by one are fixedly connected to the pressing sleeve. A blocking block is threadedly connected to one end of the connecting cylinder. A slider is slidably connected to the inside of the connecting cylinder. A second spring abuts between the slider and the blocking block. The bottom end of the pressing shaft abuts against the adjacent slider.

[0011] Preferably, the plurality of pressing shafts are distributed in a circumferential array about the center of the pressing ring, and the plurality of connecting cylinders are distributed in a circumferential array about the middle of the pressing sleeve.

[0012] Preferably, the bottom end of the transverse section of the blocking block is in a hexagonal structure, and the overall longitudinal section of the blocking block is in a "convex" shape structure.

[0013] The beneficial effects of this utility model are as follows: the connecting seat and transparent protective plate can provide all-round shielding protection for the lens on the action camera body, preventing the lens on the action camera body from being directly exposed to the external environment and damaged. When it is necessary to disassemble the transparent protective plate, the rotating ring can be rotated. The rotation of the rotating ring will drive the four second hook blocks to move away from the first hook block at the same time. When the four second hook blocks are not in contact with the four first hook blocks, the abutment can be removed from one side of the transparent protective plate, and then the transparent protective plate can be removed from the connecting seat. This achieves quick disassembly of the transparent protective plate, avoiding the need for cumbersome disassembly with tools, thereby shortening the disassembly time and improving the safety and convenience of the disassembly operation. After the transparent protective plate is installed, the abutment can press the transparent protective plate tightly onto the connecting seat under the action of the pressure structure, thereby improving the sealing performance of the transparent protective plate after installation and improving the protection effect on the lens.

[0019] 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.

[0020] Please see Figures 1-4As shown, a lens protection mechanism for an action camera includes an action camera body 1. A connecting seat 2 is fixedly connected to the action camera body 1. A transparent protective plate 3 is engaged at one end of the connecting seat 2, and a retaining sleeve 4 is engaged at the other end of the connecting seat 2. The retaining sleeve 4 abuts against the transparent protective plate 3. A fixing structure 6 is provided on the retaining sleeve 4. The fixing structure 6 includes a pressure ring 601 and a first hook block 602. The pressure ring 601 is slidably connected to the retaining sleeve 4. A plurality of first hook blocks 602 are fixedly connected to one side of the pressure ring 601. A rotating ring 604 is rotatably connected to the connecting seat 2. A plurality of second hook blocks 603, each corresponding to one of the first hook blocks 602, are fixedly connected to the outer side of the rotating ring 604. The first hook blocks 602 abut against the adjacent second hook blocks 603. A plurality of connecting blocks 606, each corresponding to one of the second hook blocks 603, are fixedly connected to the action camera body 1. A first spring 605 is fixedly connected between the second hook block 603 and the adjacent connecting block 606. A pressure applying structure 7 is provided on the pressure ring 601.

[0021] As a technical optimization of this utility model, the cross-section of one end of the first hook block 602 is trapezoidal and the cross-section of one end of the second hook block 603 is trapezoidal, so that the first hook block 602 can automatically resist the movement of the second hook block 603 during the movement of the first hook block 602 toward the second hook block 603.

[0022] As a technical optimization of this utility model, multiple first hook blocks 602 are arranged in a circular array about the center of the pressure ring 601, and multiple second hook blocks 603 are arranged in a circular array about the middle of the rotating ring 604. The stability of the fixation can be improved by having multiple second hook blocks 603 hook the first hook blocks 602 at the same time.

[0023] As a technical optimization of this utility model, a sealing ring 5 is engaged on the sleeve 4, and the sealing ring 5 abuts against the transparent protective plate 3, thereby improving the sealing performance between the sleeve 4 and the transparent protective plate 3, and thus improving the protective effect.

[0024] As a technical optimization of this utility model, the end of the longitudinal section of the abutment 4 is L-shaped, which makes it easy for the pressure ring 601 to abut against the abutment 4. One side of the transparent protective plate 3 extends to the outside of the connecting seat 2, which makes it easy for the abutment 4 to abut against one side of the transparent protective plate 3.

[0025] As a technical optimization of this utility model, the pressure structure 7 includes abutment shafts 701 and connecting cylinders 702. Multiple abutment shafts 701 are fixedly connected to the pressure ring 601. The abutment shafts 701 are slidably connected to the abutment sleeve 4. Multiple connecting cylinders 702, corresponding one-to-one with the abutment shafts 701, are fixedly connected to the abutment sleeve 4. A stop block 705 is threadedly connected to one end of the connecting cylinder 702. The stop block 705 can block the second spring 704. At the same time, unscrewing the stop block 705 can facilitate the installation and replacement of the second spring 704. A slider 703 is slidably connected inside the connecting cylinder 702. The second spring 704 is in contact between the slider 703 and the stop block 705. The bottom end of the abutment shaft 701 is in contact with the adjacent slider 703.

[0026] As a technical optimization of this utility model, multiple abutment shafts 701 are arranged in a circumferential array about the center of pressure ring 601, and multiple connecting cylinders 702 are arranged in a circumferential array about the middle of abutment sleeve 4. Therefore, multiple second springs 704 can be compressed at the same time, and the contact force can be increased, making it easier for the transparent protective plate 3 and the connecting seat 2 to contact more tightly.

[0027] As a technical optimization of this utility model, the bottom of the transverse section of the stop block 705 is hexagonal, so the stop block 705 can be easily rotated by a wrench. The longitudinal section of the stop block 705 is convex, so one end of the stop block 705 can be threadedly connected to the inside of the connecting cylinder 702.

[0028] In use, this utility model provides all-around protection for the lens on the action camera body 1 through the connecting seat 2 and the transparent protective plate 3, preventing the lens from being directly exposed to the external environment and damaged. When it is necessary to disassemble the transparent protective plate 3, the rotating ring 604 can be rotated. The rotation of the rotating ring 604 will cause the four second hook blocks 603 to move away from the first hook block 602 simultaneously, and the first spring 605 will contract. When the four second hook blocks 603 are no longer in contact with the four first hook blocks 602, the abutment 4 can be removed from one side of the transparent protective plate 3, and then the transparent protective plate 3 can be removed from the connecting seat 2. This achieves quick disassembly of the transparent protective plate 3, avoiding the need for cumbersome disassembly with tools, thus shortening the disassembly time and improving the safety and convenience of the disassembly operation. When installing the transparent protective plate 3, the transparent protective plate 3 can be installed by first... The protective plate 3 is secured to the connecting seat 2, and then the abutment 4 is fitted onto one end of the connecting seat 2. The pressure ring 601 is then pressed, and the movement of the pressure ring 601 will drive the four abutment shafts 701 to move. During the movement, the abutment shafts 701 will abut against the slider 703 and slide inside the connecting cylinder 702. The second spring 704 contracts, and the first hook block 602 will abut against the second hook block 603 as the pressure ring 601 moves, thereby causing the rotating ring 604 to rotate on the connecting seat 2. When the bottom side of the pressure ring 601 abuts against the abutment 4, the second hook block 603 will hook the first hook block 602 under the action of the first spring 605. Then the pressure ring 601 can be released. Since the four second springs 704 are in a compressed state at this time, the abutment 4 can press the transparent protective plate 3 tightly onto the connecting seat 2, thereby improving the sealing performance of the transparent protective plate 3 after installation and improving the protection effect on the lens.
