Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a new type of polarizing resin lens. Background Art

[0002] A polarizing resin lens is a lens manufactured based on the principle of light polarization, used to exclude and filter direct light in a light beam, enabling the light to enter the eye's visual image along the proper light transmission axis, making the field of view clear and natural; it is mostly used in eyes and camera lenses. Its working principle is to selectively filter light from a certain direction. By filtering out many polarized lights in diffuse reflection, the intensity of light in the sky is weakened, the sky is darkened, and the contrast between the blue sky and white clouds is increased.

[0003] When the existing laminated polarizing resin lens is in use, since the polarizing plate is arranged between two lenses, when the edge protection of the lens is insufficient, it is easy to cause air and dust to enter the laminate, resulting in stains in the lens laminate and affecting observation.

[0004] Based on this, a polarizing resin lens with edge protection is designed. Summary of the Utility Model

[0005] The utility model aims at the deficiencies existing in the prior art and provides the following technical solution: a new type of polarizing resin lens, including a lens body, and a protective ring arranged outside the lens body for protection. The lens body includes a first resin sheet, a polarizing plate, and a second resin sheet that are adhesively fixed in sequence. The protective ring includes a ring body at the edges of the first resin sheet, the polarizing plate, and the second resin sheet. A magnetic attraction member for installation is arranged outside the ring body. A positioning member is also arranged between the lens body and the ring body.

[0006] As an improvement of the above technical solution, the magnetic attraction member includes a magnet groove opened on the outside of the ring body, and a magnet block adhesively fixed in the magnet groove.

[0007] As an improvement of the above technical solution, the magnet grooves opened on the outside of the ring body are distributed in a circular array.

[0008] As an improvement of the above technical solution, the positioning member includes a sealing rubber ring arranged between the lens body and the ring body, and a skirt ring integrally formed at the edge of the ring body. The edge of the sealing rubber ring is bent and attached to the surfaces of the first resin sheet and the second resin sheet through the skirt ring. A limiting convex ring is integrally formed on the inner surface of the ring body. Limiting grooves are opened on the outside of both the first resin sheet and the second resin sheet. The sealing rubber ring is attached to the limiting grooves under the action of the limiting convex ring.

[0009] As an improvement of the above technical solution, the ring body is of a circular ring structure.

[0019] Please refer to Figures 1-3, the present utility model provides a technical solution: a novel polarizing resin lens, which includes a lens body 1 and a protective ring 2 arranged outside the lens body 1 for protection. The lens body 1 includes a first resin sheet 11, a polarizing plate 12, and a second resin sheet 13 that are adhesively fixed in sequence. The protective ring 2 includes a ring body 21 at the edges of the first resin sheet 11, the polarizing plate 12, and the second resin sheet 13. A magnetic part for installation is arranged outside the ring body 21, and a positioning part is also arranged between the lens body 1 and the ring body 21.

[0020] In this embodiment, the lens body 1 is composed of the first resin sheet 11, the polarizing plate 12, and the second resin sheet 13, and the polarizing plate 12 is located between the first resin sheet 11 and the second resin sheet 13. Thus, it is convenient for the first resin sheet 11 and the second resin sheet 13 to cooperate to protect the polarizing plate 12. The protective ring 2 is composed of a ring body 21, a magnetic part, and a positioning part. Thus, when the ring body 21 wraps around the edges of the first resin sheet 11, the polarizing plate 12, and the second resin sheet 13, it can be positioned by the positioning part, which increases the structural stability of the polarizing resin lens. The magnetic part arranged outside the ring body 21 enables the resin lens to be positioned by the magnetic part during installation, which increases the convenience of disassembly and assembly of the resin lens.

[0021] Specifically, the magnetic part includes a magnet groove 22 opened on the outside of the ring body 21 and a magnet block 23 adhesively fixed in the magnet groove 22. The magnet grooves 22 opened on the outside of the ring body 21 are distributed in a circular array.

[0022] In this embodiment, the magnetic part is composed of the magnet groove 22 and the magnet block 23. The magnet block 23 is adhesively fixed in the magnet groove 22 opened on the outer surface of the ring body 21, and the magnet grooves 22 are distributed in a circular array, enabling the resin lens to be fixed by the magnetism of the magnet block 23 during installation.

[0023] Specifically, the positioning part includes a sealing rubber ring 26 arranged between the lens body 1 and the ring body 21 and a skirt ring 27 integrally formed at the edge of the ring body 21. The edge of the sealing rubber ring 26 is bent and attached to the surfaces of the first resin sheet 11 and the second resin sheet 13 through the skirt ring 27. A limiting convex ring 24 is integrally formed on the inner surface of the ring body 21. Limiting grooves 25 are opened on the outer sides of both the first resin sheet 11 and the second resin sheet 13. The sealing rubber ring 26 fits with the limiting grooves 25 under the action of the limiting convex ring 24. The ring body 21 is a circular ring structure.

[0024] In this embodiment, a positioning member composed of a limiting convex ring 24, a limiting groove 25, a sealing rubber ring 26 and a skirt ring 27 is adopted. The sealing rubber ring 26 is installed between the lens body 1 and the ring body 21, and the edge of the sealing rubber ring 26 is attached to the surfaces of the first resin sheet 11 and the second resin sheet 13 through the skirt ring 27, so that the ring body 21 is fixed outside the lens body 1 through the cooperation of the sealing rubber ring 26 and the skirt ring 27. The limiting convex ring 24 integrally formed on the inner side of the ring body 21 abuts against the sealing rubber ring 26 to fit with the limiting groove 25, which increases the reliability of the connection between the lens body 1 and the protective ring 2.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
