Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a pair of sunglasses with the function of easy-to-change lenses. Background Art

[0002] Sunglasses, also known as sun visors or day glasses, are glasses used to block sunlight and reduce the impact of glare on the eyes. They use specific lens colors and filter coatings to reduce the transmission of visible light, ultraviolet (UV) and other harmful light to protect the eyes and provide a comfortable visual experience.

[0003] Traditional sunglasses include frames on the left and right sides respectively, with lenses arranged in the frames, a center bridge arranged between the frames on both sides, nose pads arranged below the center bridge on each frame, and temples hingedly arranged on the other side of the frame relative to the other frame. Among them, the lenses have gray, brown, green and red colors in addition to the common black. Different colors not only have functions and applicable scenarios, but also have different decorative effects. However, the lenses of a single pair of sunglasses are often of a single color and cannot be changed, and owning multiple pairs of sunglasses with different lens colors invisibly increases the consumption burden of consumers. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pair of sunglasses with a lens-changing function, which can conveniently replace lenses of different colors according to needs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising frames respectively located on the left and right sides, lenses are arranged in the frames, a middle beam is arranged between the frames on the two sides, each frame is hingedly provided with a temple on the other side of the other frame, a limiting skirt is arranged on the inner periphery of the rear of the frame, and a lens mounting groove for mounting the lens is formed in front of the limiting skirt, each lens is located below close to the middle beam and above away from the middle beam and is respectively provided with magnetic posts in the front-to-back direction, the limiting skirt and each magnetic post are provided with magnetic holes corresponding to the magnetic posts, the magnetic post is provided with a protruding portion located behind the lens, the protruding portion is plugged into the magnetic hole, and a magnetic block attracted to the magnetic post is arranged behind the magnetic hole.

[0006] By adopting the above technical solution, when it is necessary to install the sunglass lens, the lens is roughly aligned with the front of the frame and then the magnetic pole is inserted into the magnetic hole. Under the guidance of the magnetic hole, the lens is accurately aligned with the lens mounting groove and installed in the lens mounting groove. At this time, the magnetic pole and the magnetic block are attracted to maintain the installation state. When it is necessary to remove or replace the sunglass lens, it is only necessary to press the back of the lens with a finger or a tool. The above structure has the following advantages: ① The force generated by the magnetic attraction combines the lens and the frame, and the lens can be easily disassembled and assembled without the help of tools. Due to the low difficulty of disassembly and assembly, users are more willing to replace different lenses according to different needs, thereby meeting the needs of different occasions and appearance matching. When purchasing, they only need to purchase the lens and replace it by themselves, reducing the consumer burden; ② The two-point magnetic attraction structure not only cooperates with the lens mounting groove to form a stable installation structure, but also stably guides the lens to be installed into the lens mounting groove through the raised magnetic pole at the rear, making installation more convenient.

[0007] The utility model is further configured as follows: the raised portion includes a cylindrical section and a truncated cone section from front to back, the large end of the truncated cone section is connected to the cylindrical section and has the same diameter as the cylindrical section, and the magnetic hole includes a cylindrical portion consistent with the shape of the cylindrical section and a truncated cone portion consistent with the shape of the truncated cone section from front to back.

[0008] By adopting the above technical solution, the frustum segment is easier to enter the magnetic hole due to its smaller cross-section, and automatically corrects the centering of the magnetic hole and the magnetic column during the process of entering the magnetic hole, making the installation of the lens more convenient.

[0009] The utility model is further configured as follows: it also includes an inverted V-shaped nose pad, the lower part of the nose pad is supported on the wearer's nose bridge, an extension part extending to a position close to the nose bridge is arranged below the middle bridge, and the middle bridge is provided with an adjustment mechanism for adjusting the height of the nose pad.

[0010] By adopting the above technical solution, the traditional nose pads are supported on both sides of the nose bridge, which will cause continuous compression on the nose bridge during wearing of sunglasses. Since the supporting points are small, it will not only cause discomfort over time but also cause deformation of the nose bridge. Therefore, the nose pads are adjusted to an inverted V shape, and a supporting area above the nose bridge is added in addition to the traditional supporting points on both sides of the nose bridge, thereby increasing the supporting area and reducing the pressure. The adjustment mechanism can be used to adjust different heights to suit different wearers.

[0011] The utility model is further configured as follows: the adjustment mechanism includes an adjustment hole, a sliding hole, an adjustment plate and an adjustment bolt; the sliding hole is arranged below the middle beam along the up-down direction; the upper end of the adjustment plate slides in the sliding hole, and the lower end extends outside the sliding hole and is used to fix the nose pad; the adjustment hole is arranged above the middle beam along the up-down direction and is connected to the sliding hole; the adjustment bolt includes a head and a rod; an operating groove for rotation of the head is arranged at the upper end of the adjustment hole; a limiting rib is arranged circumferentially below the operating groove; a limiting groove is circumferentially arranged on the rod for rotationally cooperating with the limiting rib; a threaded hole cooperating with the thread of the rod is arranged above the adjustment plate.

[0012] By adopting the above technical solution, the head of the adjusting bolt can be rotated to move the adjusting plate up and down along the sliding hole, and the wearer can adjust it according to the actual height of the nose bridge, so that it fits the nose bridge more closely, is easier to operate, and is more stable to wear.

[0013] The utility model is further configured as follows: the nose pad comprises a frame and a rubber layer covering the frame, and the frame is a deformable strip-shaped metal piece.

[0014] By adopting the above technical solution, the deformable strip-shaped metal piece is used as the skeleton of the nose pad, and the wearer can adjust it according to the actual shape of the nose bridge, so that it fits the nose bridge more closely and is more stable to wear.
