Description

Technical Field

[0001] This utility model relates to the field of eyeglass structure technology, specifically to a hinged eyeglass structure. Background Technology

[0002] Eyeglass frames are an important component of eyeglasses, primarily serving to support the lenses. Aesthetically pleasing frames also contribute to their appearance. Materials include metal, plastic or resin, and natural materials. However, most eyeglass temples on the market currently use a single hinge design, simply fulfilling the function of a hinge. This design is simplistic, lacks design appeal, and offers limited flexibility.

[0003] Chinese patent CN219266708U discloses a hinged eyeglass frame structure for achieving a rotating connection between the frame and the temples.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: In actual use, when the temples of the glasses rotate excessively, the above structure does not have the ability to buffer excessive rotation, which leads to the risk of the temples breaking when excessive rotation occurs. Summary of the Invention

[0005] The purpose of this invention is to achieve a buffering effect when the temples of the glasses rotate excessively by using an elastic element and a sliding rotating bracket structure, thereby preventing the temples from breaking and overcoming the problems mentioned in the background art.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows: A hinged eyeglass structure includes a frame with two symmetrically distributed lenses, rotating parts connected to both sides of the frame, and an adjustment part on the side of the frame near the rotating parts to accommodate users with different head sizes.

[0007] Further defining the above technical solution, the rotating component includes a rotating bracket that is slidably connected to the side of the frame. The rotating bracket is rotatably connected to a rotating shaft, and limit rings are connected to the outer arc surfaces at both ends of the rotating shaft. The structural combination of the rotating bracket and the rotating shaft can improve the stability of the rotating connection combination of this structure.

[0008] Further defining the above technical solution, the limiting rings are symmetrically arranged at both ends of the rotating shaft. The limiting rings contact the rotating bracket and the rotating shaft at the rotatable connection point. The limiting rings can improve the rotational stability of the rotating shaft and prevent the rotating shaft from accidentally sliding out of the rotating bracket.

[0009] Further defining the above technical solution, the outer arc surface of the rotating shaft is connected to a connector, and the other end of the connector is connected to a temple. The rotating bracket, rotating shaft, limiting ring, connector, and temple are symmetrically arranged on both sides of the frame. The symmetrical structure reduces the difficulty of wearing this structure and improves the user's comfort.

[0010] Further defining the above technical solution, the temple of the glasses has a cavity inside, and a cover plate is snapped to the outside of the temple. An elastic element is slidably connected inside the cover plate. The elastic element can limit the rotation angle of the temple of the glasses, and when excessive rotation occurs, it can slide elastically inward to achieve a buffering effect against excessive rotation.

[0011] Further defining the above technical solution, the end of the elastic element near the temple of the eyeglasses is connected to several springs that are linearly and equally spaced. The other end of the spring is connected to the inner wall of the temple of the eyeglasses, and the end of the elastic element away from the spring is in contact with the side of the eyeglass frame. The elastic sliding effect of the elastic element can be achieved through the spring.

[0012] Further defining the above technical solution, the adjusting component includes an adjusting groove disposed on the side of the frame near the rotating component. A sliding member is slidably connected to the inner wall of the adjusting groove. The end of the sliding member away from the frame is connected to the rotating bracket. The combination of the adjusting groove and the sliding member can achieve the effect of adjusting the distance between the temples of the glasses, thereby achieving the effect of being compatible with the head circumference of different users.

[0013] Further defining the above technical solution, leaf springs are symmetrically connected to both sides of the outer arc surface of the sliding member, and the other end of the leaf springs is connected to the inner sidewall of the adjusting groove. The structure of the leaf springs enables the sliding member to achieve the effect of elastic sliding in the center.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Excessive rotation buffer: This structure can buffer the excessive rotation of the temples of the glasses by means of elastic elements and sliding rotating brackets; 2. Compatible with different head circumferences: This structure is compatible with different head circumferences due to its elastic sliding rotating bracket. Attached Figure Description

Detailed Implementation

[0018] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0019] Example 1: This example provides a hinged eyeglass structure, such as... Figures 1-5 As shown, the glasses include a frame 1, which has two symmetrically distributed lenses 2. Rotating components 3 are connected to both sides of the frame 1. An adjustment component 4 is provided on the side of the frame 1 near the rotating component 3 to accommodate users with different head sizes.

[0020] The rotating component 3 includes a rotating bracket 301 that is slidably connected to the side of the frame 1. The rotating bracket 301 is rotatably connected to a rotating shaft 302, and the outer arc surfaces at both ends of the rotating shaft 302 are connected to limit rings 303.

[0021] Limiting rings 303 are symmetrically arranged at both ends of the rotating shaft 302. The limiting rings 303 are in contact with the rotating bracket 301 and the rotating shaft 302 at the rotatable connection point. A connector 304 is connected to the outer arc surface of the rotating shaft 302. The other end of the connector 304 is connected to the temple 305. The rotating bracket 301, rotating shaft 302, limiting rings 303, connector 304 and temple 305 are symmetrically arranged on both sides of the frame 1. The temple 305 has a cavity inside. A cover plate 306 is snapped to the outside of the temple 305. An elastic element 307 is slidably connected inside the cover plate 306. A number of springs 308 are linearly and equally spaced at one end of the elastic element 307 near the temple 305. The other end of the springs 308 is connected to the inner wall of the temple 305. The end of the elastic element 307 away from the springs 308 is in contact with the side of the frame 1.

[0022] The specific working principle is as follows: This structure can effectively improve the stability when wearing glasses. Compared with the traditional structure, when the temple 305 is squeezed and causes excessive rotation, this structure can prevent the rotating structure from breaking by sliding the rotating bracket 301 and contracting the elastic element 307 inward.

[0023] Example 2: This example provides a hinged eyeglass structure, such as... Figures 1-5 As shown, the adjustment component 4 includes an adjustment groove 401 disposed on the side of the frame 1 near the rotating component 3. A sliding member 403 is slidably connected to the inner wall of the adjustment groove 401. One end of the sliding member 403 away from the frame 1 is connected to the rotating bracket 301. Leaf springs 402 are symmetrically connected to both sides of the outer arc surface of the sliding member 403. The other end of the leaf spring 402 is connected to the inner wall of the adjustment groove 401.

[0024] The specific working principle is as follows: This structure can reduce the risk of breakage of the rotating connection structure of the temple 305. At the same time, this structure can be elastically adjusted according to the wearer's head circumference. When using this structure, the wearer wears it on the face through the temple 305. During the wearing process, the wearer can pull the temple 305 to both sides, which can drive the rotating bracket 301 to slide elastically in the horizontal direction, thereby changing the distance between the temples 305, and thus achieving the effect of elastic adjustment according to the wearer's head circumference.

[0025] When the structure is compressed, causing the temple 305 to rotate excessively, the temple 305 rotates beyond the normal rotation range, causing the elastic element 307 to contact the side of the frame 1 and compress it. The elastic force generated by the compression of the spring 308 can buffer the excessive rotation of the temple 305, thereby reducing the degree of excessive rotation. At the same time, the rotational pulling caused by the excessive rotation of the temple 305 causes the rotating bracket 301 to slide outward, thereby preventing jamming between the rotating shaft 302 and the connecting piece 304, and thus preventing the rotating structure from breaking.

[0026] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
