Description

TECHNICAL FIELD

[0001] The utility model relates to glasses technical field especially relates to a glasses frame structure. BACKGROUND

[0002] The glasses frame core is composed of a rim, a temple and a support leaf, and the current mainstream products, whether metal or non-metal material, are mainly characterized by "integrated fixation": the rim and the temple are fixed by a hinge, and the support leaf is fixed on the inner side of the rim by welding, pasting or screwing. Each component lacks flexibility and is difficult to disassemble and replace independently.

[0003] From the function, the existing design and user demand exist mismatch: on the one hand, the user's demand for personalization (such as changing color and material according to occasion) and low-cost use (such as replacing only the lens and keeping the frame) is increasing, but the fixed structure needs to replace the frame as a whole, which increases the cost and causes waste of resources; on the other hand, the fixed support leaf cannot be replaced in time after damage, and is inconvenient to replace.

[0004] That is, the pain points of the prior art are at least:

[0005] 1. Components cannot be replaced: most components cannot be disassembled, and only a few (such as screw-fixed support leaves) need professional tools for maintenance. Ordinary users cannot replace worn-out or outdated components independently, especially for different occasions, different colors and different lenses, which can only replace the frame as a whole.

[0006] 2. The opening angle of the temple is limited: generally limited within 90°, which needs to be accurately aligned with the ear when wearing (not friendly to the elderly and children), the clamping force adjustment range is small (large head circumference is compressed, small head circumference is loose), and accidental over-angle can easily cause hinge fracture and temple deformation.

[0007] 3. The support leaf is fixed in the structure, which is inconvenient to replace after damage or aging, affecting the wearing experience.

[0008] With the upgrading of consumption, the user's demand for glasses has shifted from "function satisfaction" to "experience optimization", and the existing fixed structure and limited opening angle cannot meet the diversified demand. The replaceable component design can reduce the use cost and meet the individualization demand, and the over-90° opening angle can improve the wearing convenience, expand the user coverage and enhance the durability, so the development of such glasses frame becomes the key direction to solve the existing pain points.

[0012] Preferably, the rotating control angle is arranged to be less than or equal to 90 degrees.

[0013] Preferably, the rotating control angle is arranged to be between 75 and 90 degrees.

[0014] Preferably, the magnetic detachable component comprises a plurality of magnetic blocks arranged on the first frame body and the second frame body, two of which are arranged on the left and right sides of the rear part of the first frame body, two of which are arranged on the left and right sides of the rear part of the second frame body, and the left and right sides of the rear part of the first frame body and the second frame body are provided with mounting grooves.

[0015] Preferably, long strip-shaped through holes are formed in the left and right sides of the glasses frame body, when the first frame body and the second frame body are installed on the glasses frame body, the two magnetic blocks on the first frame body and the second frame body are attracted to each other in front and back correspondence in the through holes.

[0016] Preferably, two rear rings are arranged around the two main glasses on the rear part of the glasses frame body, a ring of fixing rings is arranged on the outer ring wall of the two rear rings in the circumferential direction, and an inner ring groove is arranged on the inner ring wall of the second frame body in correspondence with the fixing rings.

[0017] Preferably, the detachable assembly comprises a connecting rod connected to the rear part of the spectacle frame body and an inverted U-shaped insertion part connected to the connecting rod, the supporting leaf comprises an elliptical block-shaped supporting leaf body, a semi-circular connecting segment is connected to the upper part of the side wall of the supporting leaf body away from the other supporting leaf, and a sub-leaf part identical to the upper half of the supporting leaf body is connected to the other end of the connecting segment, and the sub-leaf part, the connecting segment and the supporting leaf body form a groove for the insertion of the insertion part.

[0019] Preferably, a plastic spectacle leg sleeve is connected to the rear end of the spectacle leg body, and a sub-bridge is arranged between the upper parts of the two frames of the spectacle frame body.

[0020] The above-mentioned spectacle frame structure has at least the following beneficial effects:

[0021] 1. The supporting leaf is connected through the detachable assembly of "inverted U-shaped insertion part + groove cooperation", so ordinary users can manually insert and replace without professional tools (compared with the existing screw-fixed supporting leaf which needs a screwdriver to disassemble, the replacement efficiency is improved); the U-shaped deformation segment in the middle of the connecting rod can realize elastic deformation and adapt to the height and width of the nose bridge of different users (such as children with lower nose bridge, adults with different nose bridge heights, etc.), avoiding the "indentation and sliding" problem caused by the existing fixed supporting leaf, and improving the wearing comfort. At the same time, only the supporting leaf body needs to be replaced when the supporting leaf is damaged or aged, without the need to replace the whole spectacle frame, and the cost of a single supporting leaf is only 1 / 10 of the replacement cost of a traditional integrated frame, significantly reducing the user's use cost.

[0022] 2. The first frame body on the front side of the spectacle frame body is fixed through the cooperation of a magnetic block and a through hole, can be quickly assembled and disassembled, and the sub-eyeglass on the first frame body can be switched as needed (such as daily wearing of main eyeglass, outdoor installation of polarizing sub-eyeglass, and office installation of anti-blue light sub-eyeglass), without the need to carry multiple pairs of eyeglasses, meeting the "one frame for multiple scenes" demand;

[0023] 3. The second frame body on the rear side is positioned and magnetically attracted through "fixed ring + inner ring groove" double positioning, which not only ensures the stability of the connection, but also can replace second frame bodies of different colors and textures (such as black business suits and colored casual wear), so that users can flexibly adjust the appearance according to the dress and occasion, solving the problem of "fixed appearance and inability to personalize" of the existing frame; at the same time, the second frame body can protect the back of the main eyeglass when not in use, reduce dust adhesion and scratching, and prolong the service life of the main eyeglass.

[0024] 4. The temples have a rotating structure of "bend + axis + rotation control angle", combined with the gap between the connecting block and the temples and the outer groove buffer design, so that the opening angle of the temples can exceed 90°. The actual opening angle of the temples can reach 90-135°, compared with the opening and closing limit of less than 90° for existing conventional frames: there is no need to precisely align the ears when wearing, which is especially suitable for the elderly and children with poor hand dexterity, and the operation convenience is improved; it can be adapted to people with different head circumferences (covering the head circumference range from children to adults). Users with larger head circumferences do not feel oppressive when wearing it, and users with smaller head circumferences can also ensure stability through the natural clamping force of the temples, avoiding the problem of "too tight to press the head, too loose to slip".

[0025] 5. The rotation control angle on the connecting block is limited by the corner edge, which can accurately limit the opening / folding position of the temple. In the opening and closing process, due to the setting of the rotation control angle, the angle of the rotation control angle will press against the end of the main body of the temple during the opening and folding process, increasing the distance between the curved part and the main body of the temple. The deformation force generated will cause the two to continue to open or fold faster, further accelerating the operation of opening or folding the temple. The outer groove design provides a buffer space for rotation, prevents components from collision and deformation, and extends the service life of the frame.

[0026] 6. The auxiliary mirror bridge added between the two frames of the main body of the glasses frame is integrally formed with the frame and is made of titanium alloy. It can effectively resist lateral external force impact and solve the problem of easy deformation of the single mirror bridge of the existing frame. At the same time, the titanium alloy is combined with the plastic temple cover, which greatly reduces the weight of the whole frame. It can be well reset after being stepped on or bent. It is lighter than the traditional metal frame and there is no pressure on the nose bridge or ears when worn for a long time.

[0027] In summary, this utility model not only addresses the core pain points of existing eyeglass frames but also achieves multi-dimensional optimization in terms of user experience, cost, and scenario adaptability. It is suitable for industrial mass production (all structures can be achieved through conventional laser welding, injection molding, and precision machining) and can meet the personalized and functional needs of different users, thus possessing significant practical value and market competitiveness. The beneficial effects of this utility model will be further elaborated in the examples to make them more apparent. BRIEF DESCRIPTION OF THE DRAWINGS
