Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a high-concentration aspherical optical lens. Background Technology

[0002] Aspherical optical lenses are optical lenses with an aspherical shape. Unlike traditional spherical lenses, the surface curvature of aspherical lenses can vary, often exhibiting complex curved shapes. This design can more effectively reduce aberrations and improve optical performance, and is therefore widely used in many high-end optical devices.

[0003] In existing technologies, the lens ends of traditional aspherical optical lenses are easily contaminated by dust and fingerprints, and most protective components rely on multi-layer magnetic covers and dustproof films, which are inconvenient to disassemble. Therefore, we urgently need a high-concentration aspherical optical lens. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a high-concentration aspherical optical lens, comprising a lens body and a protective component, wherein the upper surface of the lens body is coated with an anti-reflective film, an anti-static film, and a hardening layer from bottom to top, and the lower surface of the lens body is also coated with an anti-reflective film.

[0005] The protective component includes an elastic rubber protective sleeve fitted onto the outer edge of the lens body. An annular placement groove is provided in the middle of the inner wall of the elastic rubber protective sleeve. The lens body is installed inside the annular placement groove. A snap-fit ​​mechanism for the lens body is provided on the outer side of the elastic rubber protective sleeve.

[0006] As an improvement to the above technical solution, the anti-reflective film is a multilayer MgF2 / SiO2 alternating coating with a total thickness of 200-400nm.

[0007] As an improvement to the above technical solution, the antistatic film is an ITO conductive layer component, and the hardening layer is a diamond-like carbon coated component.

[0008] As an improvement to the above technical solution, the snap-fit ​​mechanism includes square slots on both sides of the outer surface of the elastic rubber protective sleeve, and the two square slots are symmetrically distributed. An installation groove is provided in the middle of the interior of the square slots. Limiting slots are provided at the upper and lower ends of the interior of the square slots. The limiting slots are located at the upper and lower ends of the installation groove, and the limiting slots penetrate the interior of the elastic rubber protective sleeve.

[0009] As an improvement to the above technical solution, the snap-fit ​​mechanism further includes two fixing rings. The two fixing rings are snapped onto the upper and lower edges of the lens body and located inside the elastic rubber protective sleeve. Several springs are fixedly installed inside the mounting groove, and a pull plate is movably installed inside the square snap-fit ​​groove. The other ends of the several springs are fixedly connected to the inner surface of the pull plate.

[0010] As an improvement to the above technical solution, the inner surface of the pull plate is provided with limit plates at both the upper and lower ends. The limit plates are respectively inserted into the inside of the limit slots, and the ends of the limit plates are snapped onto the outside of the fixing ring. The upper and lower ends of the pull plate are provided with protrusions. The height of the protrusions is slightly higher than that of the elastic rubber protective sleeve, and the pull plate, protrusions, and limit plates are integrally formed.

[0011] As an improvement to the above technical solution, the outer surface of the elastic rubber protective sleeve is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are:

[0013] By covering the outside of the lens body with an elastic rubber protective sleeve and installing the lens body in the annular placement groove opened on the inner wall of the elastic rubber protective sleeve, the lens body can be initially positioned and a protective function can be generated. At the same time, a snap-fit ​​mechanism is set on both sides of the elastic rubber protective sleeve. The snap-fit ​​mechanism locks the elastic rubber protective sleeve in place of the traditional magnetic cover. While reducing the number of components, it can also avoid magnetic interference, increase the protection function of the lens body, and increase the convenience of fixing.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Please see Figure 1-5 The present invention provides a technical solution: a high-concentration aspherical optical lens, including a lens body 100 and a protective component. The upper surface of the lens body 100 is coated with an anti-reflective film 110, an anti-static film 120 and a hardening layer 130 from bottom to top, and the lower surface of the lens body 100 is also coated with an anti-reflective film 110.

[0022] The protective component includes an elastic rubber protective sleeve 200 fitted around the outer edge of the lens body 100. An annular placement groove 210 is provided in the middle of the inner wall of the elastic rubber protective sleeve 200. The lens body 100 is installed inside the annular placement groove 210. A snap-fit ​​mechanism for the lens body 100 is provided on the outer side of the elastic rubber protective sleeve 200.

[0023] In this embodiment, an elastic rubber protective sleeve 200 is fitted on the outside of the lens body 100, and the lens body 100 is installed in the annular placement groove 210 opened on the inner wall of the elastic rubber protective sleeve 200. This can perform initial positioning of the lens body 100 and provide a protective function. At the same time, a snap-fit ​​mechanism is provided on both sides of the elastic rubber protective sleeve 200. The snap-fit ​​mechanism locks the elastic rubber protective sleeve 200 to replace the traditional magnetic cover, which reduces the number of components and avoids magnetic interference.

[0024] Specifically, the anti-reflective film 110 is a multilayer MgF2 / SiO2 alternating coating with a total thickness of 200-400nm.

[0025] In this embodiment, the anti-reflective film 110 with alternating layers of MgF2 / SiO2 covers the visible light to infrared bands, while also reducing the reflection loss on the surface of the lens body 100, improving the light-gathering efficiency, and the inorganic material coating has a long lifespan.

[0026] Specifically, the antistatic film 120 is an ITO conductive layer component, and the hardening layer 130 is a diamond-like carbon coated component.

[0027] In this embodiment, the antistatic film 120 uses an ITO conductive layer to achieve higher optical efficiency and avoids the problem of reduced light transmittance caused by electrostatic adsorption, while the hardening layer 130 uses a diamond-like carbon coating to significantly improve wear resistance and meet optical performance requirements.

[0028] Specifically, the snap-fit ​​mechanism includes square slots 220 formed on both sides of the outer surface of the elastic rubber protective sleeve 200, with the two square slots 220 being axially symmetrically distributed. An installation groove 222 is formed in the middle of the interior of each square slot 220. Limiting slots 221 are formed at the upper and lower ends of the interior of the square slot 220, located at the upper and lower ends of the installation groove 222 and penetrating the interior of the elastic rubber protective sleeve 200. The snap-fit ​​mechanism also includes two retaining rings 300, which are respectively snapped onto the upper and lower edges of the lens body 100 and located inside the elastic rubber protective sleeve 200. The mounting groove 222 contains a fixed mounting ring. The pull plate 400 is movably installed inside the square slot 220, which is equipped with several springs 430. The other end of the springs 430 is fixedly connected to the inner surface of the pull plate 400. Limiting inserts 420 are provided at both the upper and lower ends of the inner surface of the pull plate 400. The limiting inserts 420 are respectively inserted into the inside of the limiting slot 221, and the end of the limiting insert 420 is engaged with the outside of the fixing ring 300. The upper and lower ends of the pull plate 400 are provided with protrusions 410. The height of the protrusions 410 is slightly higher than that of the elastic rubber protective sleeve 200. The pull plate 400, the protrusions 410, and the limiting inserts 420 are integrally formed. The outer surface of the elastic rubber protective sleeve 200 is provided with anti-slip texture.

[0029] In this embodiment, a snap-fit ​​mechanism for the lens body 100 is provided on the outside of the elastic rubber protective sleeve 200. Under the action of the snap-fit ​​mechanism, when it is necessary to fix the lens body 100, the lens body 100 is first installed inside the annular placement groove 210. Then, the protrusions 410 provided at the upper and lower ends of the pull plate 400 are pulled to move the limiting insert plate 420 inside the limiting slot 221. At this time, the spring 430 is in a stretched state. When the limiting insert plate 420 is fully inserted into the limiting slot 221, the fixing rings 300 are snapped at the upper and lower edges of the lens body 100 respectively. Then, the protrusions 410 are released, the spring 430 quickly returns to its original position, and the limiting insert plate 420 is snapped at the outside of the fixing ring 300, thus completing the limiting and fixing of the lens body 100. The whole process is convenient and quick, thereby increasing the convenience of use.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
