[0027] The rubber snap ring 2 nested outside the lens body 1 plays a key buffering and fixing role. The protrusion 202 at one end of the rubber snap ring 2 can be embedded into the groove 201 at the other end. This kind of movable connection enables the rubber snap ring 2 to be self-adapted to the size of the lens body 1, tightly fit the periphery of the lens, prevent the lens from shaking in the snap ring, and avoid the lens from being directly damaged when the lens is extruded or collided by external force, and protect the frame 3 which is composed of the upper frame 301 and the lower frame 302. The clamping groove 303 inside the upper frame 301 cooperates with the clamping rod 304 inside the lower frame 302. By embedding the clamping rod 304 into the clamping groove 303, the upper frame 301 and the lower frame 302 are quickly and conveniently connected, and are also convenient to disassemble, so as to maintain or replace the lens. The rubber snap ring 2 is located between the upper frame 301 and the lower frame 302, and the protective frame 3 provides an additional protective barrier for the whole lens to resist the impact, scratching and the like from the outside world. The protective outer layer outside the lens body 1 is made of high-strength, high-hardness and wear-resistant, anti-aging organic silicon material. Its special nano coating treatment forms a super-hydrophobic, anti-oil protective film. When the lens is scratched in daily life, such as contacting with a hard object, the protective outer layer blocks the damage of the hard object to the lens body 1 due to its high hardness and wear resistance. When encountering rain, oil stains and other pollutants, the super-hydrophobic nano coating makes water droplets, oil stains and the like unable to adhere, roll off or be easily wiped off, so as to always maintain the optical performance of the lens. The rubber snap ring 2, the protective frame 3 and the protective outer layer form a three-layer protection system from inside to outside. The rubber snap ring 2 buffers the daily small collision, the protective frame 3 resists the impact of large external force, and the protective outer layer is wear-resistant and anti-pollution. The three work together to greatly reduce the risk of lens damage, significantly prolong the service life of the lens, reduce the use cost, and improve the maintenance efficiency. The design of the clamping groove 303 and the clamping rod 304 of the protective frame 3 enables the assembly process to be completed without complex tools, and the operator can easily assemble and disassemble the upper frame 301 and the lower frame 302, so as to facilitate the regular inspection, cleaning or replacement of the lens, ensure that the lens is always in good working condition, and the super-hydrophobic and anti-oil properties of the protective outer layer enable the lens to remain clean in various complex environments, avoid abnormal light refraction caused by the adhesion of pollutants, always maintain good optical transmittance, ensure clear and stable imaging, and meet the needs of high-precision optical applications.

[0028] The utility model discloses a concave slot 201 inner wall is provided with the positioning groove 203 around, and the convex block 202 outer surface is provided with the locating block 204 around, and the locating block 204 can embed inside the positioning groove 203, and the locating block 204 is rubber material, and the outside of locating block 204 is arc shape, and the rubber snap ring 2 inside is provided with the limit groove 205, and the edge of lens body 1 all embeds inside the limit groove 205, and the clamping bar 304 is connected with the rubber snap ring 2 with bolt and card slot 303, and the upper frame 301 and the lower frame 302 inside all are provided with annular groove 305, and the rubber snap ring 2 is located inside two annular grooves 305, and the annular groove 305 inner wall both ends all are installed with the anti -collision strip 306, and the anti -collision strip 306 inside is arc shape, and the inside of anti -collision strip 306 is hollow, and the annular groove 305 inner wall is installed with the shock strip 307, and the shock strip 307 outside arc shape and inside hollow, and the protection frame 3 is provided with threaded hole 308 through, and the threaded hole 308 inside embeds the bolt setting,

[0029] The positioning groove 203 is arranged around the inner wall of the groove 201 and cooperates with the positioning block 204 on the outer surface of the protrusion 202. The positioning block 204 is made of rubber and has an arc-shaped outer side. This design can not only make the rubber snap ring 2 more accurately positioned during connection, prevent it from moving axially or radially, and ensure that the rubber snap ring 2 tightly surrounds the lens body 1, but also further buffer the impact force that the lens may receive by utilizing the elasticity of rubber. The limiting groove 205 on the inner side of the rubber snap ring 2 stably embeds the edge of the lens body 1, strictly limits the movement space of the lens, and almost reduces the shaking of the lens during daily use. From multiple angles, the stability of the lens is ensured. The clamping rod 304 and the clamping groove 303 are connected with the rubber snap ring 2 by bolts, so that the protection frame 3 and the rubber snap ring 2 form a more stable overall structure. The tightening effect of the bolts can resist large external impact forces and prevent the protection frame 3 from loosening. The annular groove 305 on the inner side of the upper frame 301 and the lower frame 302 provides a dedicated placement space for the rubber snap ring 2. The anti-collision strips 306 on the inner wall of the annular groove 305 have arc-shaped inner sides, which can effectively disperse the impact force when the lens is subjected to side impact. The hollow structure can absorb energy by deforming itself. At the same time, the shock-absorbing strips 307 on the inner wall of the annular groove 305 are also arc-shaped on the outer side and hollow, which further enhances the buffering effect. Whether it is vertical or horizontal vibration and impact, it can be weakened layer by layer, and the lens body 1 is protected to the greatest extent from being damaged. The protective outer layer on the outer side of the lens body 1 still relies on the properties of high-strength, high-hardness, wear-resistant, and anti-aging organic silicon material, as well as the super-hydrophobic and oil-resistant nano coating, to continuously play the role of blocking hard damage and preventing stains from adhering in the daily scraping and contamination scenarios, ensuring that the lens always maintains excellent optical performance. The newly added positioning groove 203, positioning block 204, and limiting groove 205 design makes the fixing of the lens in the rubber snap ring 2 extremely accurate, reducing the risk of lens wear caused by shaking and displacement. In combination with the anti-collision strips 306 and the shock-absorbing strips 307, the lens is protected from impact from all directions, greatly improving the protection level of the lens and significantly extending the service life of the lens. Reducing the cost of frequent lens replacement, the bolt connection of the protection frame 3 and the rubber snap ring 2 makes the overall structure more stable and reliable, and in the face of complex and harsh use environments such as outdoor falling and collision, the lens can also be ensured to be safe and sound, reducing the probability of lens damage caused by loose structure and enhancing the durability of the entire device. Although the structure has been enhanced, the clamping groove 303 and the clamping rod 304 of the protection frame 3 are designed in combination with the bolt connection, which still ensures that the operator can easily and quickly disassemble the protection frame 3 when maintaining and cleaning the lens, and perform operations such as inspection and wiping on the lens without affecting the daily maintenance process. The protective outer layer continuously keeps the lens clean and always ensures high-precision optical imaging effects, meeting the needs of professional optical applications.
