Description

Technical Field

[0001] The utility model relates to the technical field of optical lens groups, in particular to an optical lens group with protective performance. 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 over a long period of 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] However, some new demands have also been generated during the use of existing optical lenses. For example, the protective function of optical lenses is relatively single, and users are prone to drop them to the ground when wearing them, causing lens wear. Therefore, corresponding improvements need to be made in this regard.

[0004] At present, publication number CN220691172 discloses an optical lens with protective performance, including a lens body, a raised portion is arranged on the upper surface of the middle part of the lens body, an arc-shaped groove is arranged on the lower surface of the middle part of the lens body, a protective ring for protection is formed integrally on the upper surface of the edge of the lens body, a card groove is arranged on the outer surface of the connection between the lens body and the protective ring, and a limiting groove is arranged on the outer surface of the connection between the lens body and the protective ring; the protective ring is integrally formed on the upper surface of the lens body, so that the protective ring protects the raised portion arranged on the upper surface of the lens body to prevent hard objects from colliding with the surface of the raised portion and causing scratches, and the limiting groove is arranged on the inner surface of the connection between the lens body and the protective ring, and the edges of the glass fiber polyester film and the nano anti-fouling film are both located in the limiting groove, so that the limiting groove is convenient for protecting the edges of the glass fiber polyester film and the nano anti-fouling film.

[0005] In order to solve the problem of optical lens protection, the existing technology adopts a protective ring that is integrally formed on the upper surface of the lens body, so that the protective ring protects the raised portion set on the upper surface of the lens body. However, there is still a problem that the protective buffering effect of the lens is not good and the stability of the lens protection is not high enough, which leads to the problem that the lens is easily damaged.

[0013] A further improvement of the technical solution of the utility model is that the protection component includes a protection sleeve, which is installed inside the placement groove, and a protection pad is fixedly connected to the surface of the protection sleeve. The protection pad and the protection layer have a protection effect and can instantly absorb and disperse impact energy.

[0027] Specifically, the lens 4 is placed inside the fixing kit 1. When the lens 4 is impacted, the buffer head 25 and the rubber block 24 buffer the impact force for the first time. The buffer head 25 and the rubber block 24 are made of rubber material, which has a rebound buffering effect when impacted. Then, by squeezing the buffer block 20, the spring 22 between the first gasket 23 and the second gasket 21 is squeezed, and the impact force is buffered for the second time, so that the lens 4 can be effectively protected and buffered when it falls.

[0028] Example 2

[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the fixing kit 1 includes a fixing sleeve 10, the fixing sleeve 10 is installed with the surface of the lens 4, the fixing sleeve 10 is provided with a placement groove 11, the fixing sleeve 10 is fixedly connected with connecting blocks 12 on both sides of the fixing sleeve 10, the surface of the connecting block 12 is threadedly connected with a fixing bolt 13, one end of the fixing sleeve 10 is provided with a clamping groove 15, and one end of the fixing sleeve 10 is fixedly connected with a clamping block 14, the protective component 3 includes a protective sleeve 31, the protective sleeve 31 is installed in the placement groove 11, the surface of the protective sleeve 31 is fixedly connected with a protective pad 30, the protective sleeve 31 includes a protective layer 310, the protective layer 310 is fixedly connected to the surface of the protective pad 30, the surface of the protective layer 310 is provided with a through hole 312, the bottom of the protective layer 310 is fixedly connected with an anti-slip layer 311, and the surface of the anti-slip layer 311 is fixedly connected with an anti-slip block 313;

[0030] Specifically, there are two fixing sleeves 10, and the connecting blocks 12 are respectively fixed at one end of the two fixing sleeves 10, and the connecting blocks 12 are connected by the fixing bolts 13, so that the two fixing sleeves 10 can be connected. When the fixing sleeves 10 are connected, the clamping block 14 connected to one end of the fixing sleeve 10 is clamped into the inside of the clamping groove 15, and then the two groups of fixing sleeves 10 can be tightly connected.

One end of each fixing sleeve 10 is connected by a fixing bolt 13 to connect the connecting block 12, and then the two fixing sleeves 10 can be connected. When the fixing sleeves 10 are connected, the clamping block 14 connected to one end of the fixing sleeve 10 is clamped into the inside of the clamping groove 15, and then the two groups of fixing sleeves 10 can be tightly connected. The material of the protective pad 30 and the protective layer 310 is sponge material. The protective pad 30 and the protective layer 310 have a protective effect and can instantly absorb and disperse impact energy.
