Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to a high-hardness, scratch-resistant optical lens. Background Art

[0002] Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles; then slowly cooled for a long time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to become optical lens blanks.

[0003] For example, the patent document with application number CN202020387526.0 discloses a lens group of an optical lens. The lens group of the utility model optical lens tightly bonds the first lens and the second lens through a pressure-sensitive adhesive film, and at the same time eliminates the stress at the connection part through the pressure-sensitive adhesive film to avoid the influence of stray light generated at the connection position on the imaging quality, and increases the transparency through the second anti-reflection film and the first anti-reflection film in the first lens body and the second lens body. However, the lens group of the optical lens has weak anti-fall ability, and the optical lens may be easily damaged due to external impact, which affects its normal use in the later stage.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-hardness scratch-resistant optical lens is proposed. Utility Model Content

[0007] Preferably, a second anti-collision ring is clamped on the top of the first anti-collision ring, and the overall structure of the second anti-collision ring is consistent with the overall structure of the first anti-collision ring.

[0008] Preferably, a first transparent glass is fixedly mounted on the top of the lens body, and the overall structure of the first transparent glass is the same as that of the lens body.

[0011] Preferably, the overall structure of the second anti-scratch layer is consistent with the overall structure of the first anti-scratch layer, and the outer diameter of the second anti-scratch layer is the same as the outer diameter of the lens body.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the high-hardness scratch-resistant optical lens can not only improve the anti-fall ability, but also improve the overall scratch resistance of the lens body.

[0013] 1. The utility model provides a buffer assembly so that when the first anti-collision ring or the second anti-collision ring is impacted, it applies pressure to the rubber ring provided inside, and the rubber ring reduces the impact force of the first anti-collision ring, so that the first anti-collision ring acts on the lens body provided inside the fixing ring, and the force applied to the lens body is reduced to a safe range, so as to achieve the purpose of improving the anti-fall ability;

[0014] 2. The utility model arranges the first transparent glass, the first anti-scratch layer, the second transparent glass, and the second anti-scratch layer so that the first transparent glass and the second transparent glass fix the lens body clamped therebetween, thereby improving the overall strength of the upper and lower sides of the lens body. The first anti-scratch layer and the second anti-scratch layer respectively arranged on the outer walls of the first transparent glass and the second transparent glass improve the scratch resistance of the first transparent glass and the second transparent glass.

[0031] Working principle: When using this high hardness scratch-resistant optical lens, first pass

[0032] Embodiment 1: When the first anti-collision ring 302 or the second anti-collision ring 4 is impacted, it applies pressure to the rubber ring 301 disposed inside, and the rubber ring 301 reduces the impact force of the first anti-collision ring 302, so that the first anti-collision ring 302 acts on the lens body 1 disposed inside the fixing ring 2, so that the force on the lens body 1 is reduced to a safe range;

[0033] Embodiment 2: The first transparent glass 5 and the second transparent glass 7 fix the lens body 1 clamped therebetween, thereby improving the overall strength of the upper and lower sides of the lens body 1, and the first anti-scratch layer 6 and the second anti-scratch layer 8 respectively arranged on the outer walls of the first transparent glass 5 and the second transparent glass 7 improve the scratch resistance of the first transparent glass 5 and the second transparent glass 7.
