Description

Technical Field

[0001] This utility model belongs to the field of lens technology, specifically relating to a high color reproduction resin lens with a refractive index of 1.50. Background Technology

[0002] The refractive index of resin lenses is the ratio of the speed of light in a vacuum to the speed of light in the resin lens material, reflecting the lens's ability to refract light. Currently, the mainstream refractive indices of resin lenses on the market include 1.50, 1.56, 1.60, 1.67, 1.71, and 1.74. Resin lenses also feature high color reproduction; high color reproduction resin lenses can accurately reflect and transmit true colors, especially in complex lighting environments, such as natural or artificial light, still presenting a clear and accurate visual effect.

[0003] When using existing 1.50 high color reproduction resin lenses, the lenses need to be removed and replaced due to changes in the user's vision or damage caused by impacts. However, traditional lenses are fixed in a semi-enclosed or fully enclosed manner, which makes lens removal and installation time-consuming, and the lenses are also easily damaged due to improper operation during removal and installation.

[0004] Based on this, a high color reproduction resin lens with a refractive index of 1.50 was designed and fixed with a magnetic connector. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a high color reproduction resin lens with a refractive index of 1.50. The specific technical solution is as follows:

[0006] A high refractive index, high color reproduction resin lens includes a resin lens, a frame for support is provided on the outer side of the resin lens, a magnetic connector for connection is installed between the frame and the resin lens, and a protective rubber ring is bonded to the edge of the frame.

[0007] The magnetic connector includes a retaining plate that is glued and fixed to the edge of the eyeglass frame. A limiting hole is formed on the inner side of the eyeglass frame, and a first magnet is glued and fixed in the limiting hole. A limiting sleeve is integrally formed on the outer surface of the retaining plate, and a second magnet that is attracted to the first magnet by magnetic force is glued and fixed in the limiting sleeve. An adhesive ring is glued to the inner surface of the retaining plate. A positioning hole is formed on the resin lens. A hole corresponding to the positioning hole is formed on the retaining plate. A buffer sleeve is glued in the positioning hole and the through hole. A positioning rod is inserted into the buffer sleeve, and both ends of the positioning rod are located in the hole formed in the retaining plate.

[0008] Preferably, the card plate has a "U"-shaped plate structure and is tightly attached to the outer surface of the rubber ring.

[0009] Preferably, a limiting protrusion is integrally formed on the inner surface of the rubber ring, a limiting groove is formed on the edge of the resin lens, and the limiting protrusion is bonded to the inside of the limiting groove.

[0010] Preferably, both the rubber ring and the limiting protrusion are provided with nylon ropes for support, and a buffer cavity for cushioning is provided at the connection between the rubber ring and the limiting protrusion.

[0011] Preferably, the card plate and the resin lens are connected by two positioning rods and a buffer sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A magnetic connector between the frame and the resin lens facilitates quick connection of the resin lens to the frame, making it easy to install and remove the lens and replace it. This reduces the difficulty of replacing damaged or damaged resin lenses due to changes in vision. The magnetic connector consists of a locking plate, a limiting hole, a first magnet, a limiting sleeve, a second magnet, a positioning hole, a positioning rod, and a buffer sleeve. The second magnet is bonded to the limiting sleeve integrally formed on the outer surface of the locking plate, while the first magnet is bonded to the limiting hole on the inner side of the frame. The first and second magnets attract each other magnetically, allowing the locking plate to be fixed to the frame. The positioning hole on the surface of the resin lens corresponds to the hole on the locking plate, allowing the buffer sleeve to be inserted into the positioning hole and then fixed by the inserted positioning rod. The rubber ring bonded inside the locking plate also increases the connection between the locking plate and the resin lens, thereby increasing the stability of the locking plate installed at the end of the resin lens.

[0014] 2. The U-shaped plate structure, which is in close contact with the outer surface of the rubber ring, increases the contact area between the plate and the rubber ring during bonding. The integrally formed limiting convex ring on the inner surface of the rubber ring is bonded to the limiting groove opened at the edge of the resin lens, thereby increasing the contact area when the rubber ring is bonded to the edge of the resin lens and improving the stability of the rubber ring when bonded to the edge of the resin lens. The nylon rope at the connection between the rubber ring and the limiting convex ring strengthens the tensile strength of the rubber ring and the limiting convex ring. The buffer cavity at the connection between the rubber ring and the limiting convex ring facilitates the deformation of the rubber ring when it is compressed, increasing the buffering performance of the rubber ring.

[0020] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1-4 This embodiment provides the following technical solution: a resin lens with a refractive index of 1.50 and high color reproduction, including a resin lens 2, a frame 1 for support is provided on the outside of the resin lens 2, a magnetic connector 3 for connection is installed between the frame 1 and the resin lens 2, and a protective rubber ring 4 is bonded to the edge of the frame 1.

[0022] The magnetic connector 3 includes a retaining plate 31 that is glued and fixed to the edge of the frame 1. A limiting hole 32 is opened on the inner side of the frame 1. A first magnet 33 is glued and fixed in the limiting hole 32. A limiting sleeve 34 is integrally formed on the outer surface of the retaining plate 31. A second magnet 35 that is attracted to the first magnet 33 by magnetic force is glued and fixed in the limiting sleeve 34. A rubber ring 4 is glued to the inner surface of the retaining plate 31. A positioning hole 37 is opened on the resin lens 2. A hole corresponding to the positioning hole 37 is opened on the retaining plate 31. A buffer sleeve 39 is glued in the positioning hole 37 and the through hole. A positioning rod 38 is inserted into the buffer sleeve 39. Both ends of the positioning rod 38 are located in the hole opened in the retaining plate 31.

[0023] In this embodiment, a magnetic connector 3 is provided between the frame 1 and the resin lens 2, facilitating the quick connection of the resin lens 2 to the frame 1. This makes it easier to install and remove the resin lens 2, reducing the difficulty of replacing it when damaged or due to changes in vision. The magnetic connector 3 consists of a locking plate 31, a limiting hole 32, a first magnet 33, a limiting sleeve 34, a second magnet 35, a positioning hole 37, a positioning rod 38, and a buffer sleeve 39. The second magnet 35 is bonded to the limiting sleeve 34, which is integrally formed on the outer surface of the locking plate 31. A first magnet 33 is bonded to a limiting hole 32 on the inner side of the frame 1. The first magnet 33 and the second magnet 35 are attracted by magnetic force, which makes it easy for the clamping plate 31 to be fixed to the frame 1 by the first magnet 33 and the second magnet 35. The positioning hole 37 on the surface of the resin lens 2 corresponds to the hole on the clamping plate 31, which makes it easy for the buffer sleeve 39 to be inserted into the positioning hole 37 and then fixed by the inserted positioning rod 38. At the same time, the rubber ring 4 is bonded to the clamping plate 31, which also increases the connection between the clamping plate 31 and the resin lens 2, thereby increasing the stability of the clamping plate 31 installed at the end of the resin lens 2.

[0024] Specifically, the card plate 31 has a "U"-shaped plate structure and is closely attached to the outer surface of the rubber ring 4. The inner surface of the rubber ring 4 is integrally formed with a limiting protrusion 5. The edge of the resin lens 2 is provided with a limiting groove 36, and the limiting protrusion 5 is bonded to the inside of the limiting groove 36. The rubber ring 4 and the limiting protrusion 5 are both provided with nylon ropes 6 for support. A buffer cavity 7 for cushioning is provided at the connection between the rubber ring 4 and the limiting protrusion 5.

[0025] In this embodiment, the U-shaped plate 31, which is in close contact with the outer surface of the rubber ring 4, increases the contact area when the plate 31 and the rubber ring 4 are bonded together. The limiting protrusion 5, integrally formed on the inner surface of the rubber ring 4, is bonded to the limiting groove 36 opened at the edge of the resin lens 2, thereby increasing the contact area when the rubber ring 4 is bonded to the edge of the resin lens 2 and improving the stability of the rubber ring 4 when bonded to the edge of the resin lens 2. The nylon rope 6 provided at the connection between the rubber ring 4 and the limiting protrusion 5 strengthens the tensile strength of the rubber ring 4 and the limiting protrusion 5. The buffer cavity 7 provided at the connection between the rubber ring 4 and the limiting protrusion 5 facilitates the deformation of the rubber ring 4 when it is squeezed, thereby increasing the buffering performance of the rubber ring 4.

[0026] Specifically, the card plate 31 and the resin lens 2 are connected by two positioning rods 38 and a buffer sleeve 39, which increases the stability of the connection between the frame 1 and the resin lens 2.
