Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a frameless pair of eyeglasses. Background Technology

[0002] Generally speaking, eyeglasses refer to lenses, i.e., spectacle plates, and the frames that hold the lenses in place. They are divided into framed eyeglasses with wide frames made of synthetic resin and framed eyeglasses with metal frames made of metal. Framed eyeglasses have grooves on the inside of the frame to hold the lenses in place, and temples on both sides of the frame for wearing on the face. There are also rimless glasses where the nose bridge and temples are directly connected to the lenses. Rimless glasses have a nose bridge that connects the two lenses and a hinge that connects to the outside of the lenses. However, in the use of existing technology, the lenses of rimless glasses are mostly fixed by screws / bolts. After a long period of use, the lenses will wobble. Utility Model Content

[0003] The purpose of this invention is to provide frameless glasses to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a frameless eyeglass, including a nose bridge, two lenses symmetrically arranged at both ends of the nose bridge, a hinge frame disposed at the end of the lens away from the nose bridge, and temples hinged to the hinge frame away from the lens. The end of the nose bridge is fixedly provided with a first fixing frame that matches and fits against the curvature of the side wall of the corresponding lens. The end of the hinge frame near the nose bridge is fixedly provided with a second fixing frame that matches and fits against the curvature of the side wall of the corresponding lens. Connecting ears extend towards the lens from the rear side wall of the first fixing frame and the front side wall of the second fixing frame located on both sides of the same lens. The connecting ears are fixed to the lens by a threaded assembly.

[0005] Furthermore, two limiting grooves are provided at the two ends of the lens and at the corresponding positions of the two connecting ears. Limiting blocks are provided at the angle between the first fixing frame and the connecting ear and at the angle between the second fixing frame and the connecting ear. The limiting blocks are snapped into the corresponding limiting grooves.

[0006] Furthermore, two first through holes are respectively provided on the front sidewall of the lens, and the connecting lug is provided with second through holes a and b corresponding to the positions of the corresponding first through holes. The threaded assembly includes a bolt and a nut. The bolt located on the first fixing frame side passes through the corresponding first through hole and the corresponding second through hole a in sequence and is threadedly connected to the nut. The bolt located on the second fixing frame side passes through the corresponding second through hole b and the corresponding first through hole in sequence and is threadedly connected to the nut.

[0007] Furthermore, two annular metal washers are fitted onto the bolt's threaded shaft, and the two annular metal washers correspond to each other and successively fit against the outer wall of the connecting lug and the outer wall of the lens, respectively.

[0008] Furthermore, an annular flexible washer is fitted onto the thread of the bolt between the two annular metal washers, and the annular flexible washer is in contact with the annular metal washer on the side closest to the nut.

[0009] The beneficial effects achieved by this utility model are as follows: The first and second fixing brackets fit the curvature of the lens, increasing the contact area and forming a partial wrap. They are then fixed with bolt assemblies for connecting ears on both sides, forming a multi-point fixation that reduces lens movement from both the contact surface and the fixing points.

[0010] The limiting block and the limiting groove are precisely engaged, further restricting the relative displacement between the lens and the mounting bracket.

[0011] The design of the ring-shaped metal gasket isolates the sharp edges of the bolts and nuts from contact with the lens and connecting ear surfaces, preventing scratches during tightening and protecting the integrity of the lens and connecting ear appearance.

[0012] The annular flexible gasket buffers vibrations during daily use, blocks the transmission of vibrations to the threaded assembly, effectively prevents the threaded assembly from loosening, and extends the structural stability period. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-4As shown, this utility model discloses a frameless eyeglass, including: a nose bridge 1, two lenses 2 symmetrically arranged at both ends of the nose bridge 1, a hinge frame 3 arranged at the end of the lens 2 away from the nose bridge 1, and a temple 4 hinged to the hinge frame 3 away from the lens 2. The end of the nose bridge 1 is fixedly provided with a first fixing frame 11 that matches and fits against the side wall curvature of the corresponding side lens 2. The end of the hinge frame 3 near the nose bridge 1 is fixedly provided with a second fixing frame 31 that matches and fits against the side wall curvature of the corresponding side lens 2. Connecting ears 12 and 32 extend towards the lens 2 from the rear side wall of the first fixing frame 11 and the front side wall of the second fixing frame 31 located on both sides of the same lens 2. The connecting ears 12 and 32 are fixed to the lens 2 by a threaded assembly 5.

[0016] Based on the above structure, such as Figure 1-4 As shown, during use, the first fixing bracket 11 and the second fixing bracket 31 are designed to match and fit the curvature of the lens sidewall, increasing the fixing contact surface at both ends of the lens 2 and forming a partial wrapping effect at both ends of the lens 2. At the same time, with the help of the threaded assembly 5 to fix the lens 2 to the two connecting ears 12 and 32, the lens 2 has multiple fixing points, thereby reducing the shaking of the lens 2.

[0017] Furthermore, such as Figure 2-4 As shown, two limiting grooves 21 are provided at the two ends of the lens 2 corresponding to the positions of the two connecting ears 12 and 32. Limiting blocks 13 and 33 are provided at the angle between the first fixing frame 11 and the connecting ear 12 and at the angle between the second fixing frame 31 and the connecting ear 32. The limiting blocks 13 and 33 are engaged in the corresponding limiting grooves 21. The limiting grooves 21, together with the limiting blocks 13 and 33, further limit the contact between the two ends of the lens 2 and the first fixing frame 11 and the second fixing frame 31, thereby increasing the stability of the lens 2 and further reducing the shaking of the lens 2.

[0018] Furthermore, such as Figure 2-4 As shown, two first through holes 22 are respectively provided on the front side wall of the lens 2. The connecting ears 12 and 32 are provided with second through holes a, b14 and 34 corresponding to the positions of the first through holes 22 on the corresponding side. The threaded assembly 5 includes a bolt 51 and a nut 52. The bolt 51 located on the side of the first fixing bracket 11 passes through the first through hole 22 and the second through hole a14 on the corresponding side in sequence, and is threadedly connected to the nut 52. The bolt 51 located on the side of the second fixing bracket 31 passes through the second through hole b34 and the first through hole 22 on the corresponding side in sequence, and is threadedly connected to the nut 52.

[0019] Furthermore, such as Figure 4As shown, two annular metal washers 53 are fitted onto the screw of bolt 51. The two annular metal washers 53 are respectively fitted onto the outer walls of connecting ears 12 and 32 and the outer wall of lens 2. The annular metal washers 53 prevent the edges of bolt 51 and nut 52 from directly contacting the surfaces of lens 2 and connecting ears 12 and 32 when they are tightened, thereby preventing scratches on the surfaces of lens 2 and connecting ears 12 and 32.

[0020] Furthermore, such as Figure 4 As shown, an annular flexible washer 54 is fitted onto the thread of the bolt 51 between the two annular metal washers 53. The annular flexible washer 54 fits against the annular metal washer 53 on the side near the nut 52. The flexible washer 53 can alleviate the vibration of the glasses during daily use and transmit it to the threaded assembly 5, thereby preventing the threaded assembly 5 from loosening.

[0021] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
