Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an eyeglass that is easy to disassemble and reassemble to prevent lens breakage. Background Technology

[0002] As an essential daily vision correction or decorative device, the stability of lens installation and the ease of disassembly are core user needs, and existing technologies still have significant shortcomings in these two aspects.

[0003] Regarding lens installation and protection, traditional eyeglasses typically use rigid clips or screws to connect lenses to the frame, lacking a cushioning structure. When the glasses are subjected to external impact, pressure, or drops, the hard contact between the lens and the frame can easily lead to stress concentration, potentially causing the lens to break (explode). This not only affects safety but also increases replacement costs. Some rimless or semi-rimless eyeglasses use even simpler lens fixing methods, resulting in an even higher risk of lens breakage and failing to meet users' safety requirements.

[0004] In terms of ease of installation and maintenance, the installation of lenses in existing eyeglasses often requires specialized tools and is secured by tightening screws or clips, which is cumbersome and can easily damage the edges of the lenses. The connection between hinges and frames often uses welding or multi-screw fixing structures, which are complex to assemble, have low production efficiency, and make disassembly difficult if lens replacement or hinge repair is needed later, causing many inconveniences for users. In addition, the compatibility between lenses and frames, and between hinges and frames, in traditional structures is poor, and different specifications of lenses or hinges are not interchangeable, further limiting the flexibility of installation and maintenance.

[0005] In summary, existing eyeglasses are deficient in terms of lens explosion protection and ease of installation. There is an urgent need for a new eyeglass structure that can effectively reduce the risk of lens explosion and simplify the installation and disassembly process to address the pain points of existing technologies. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

[0007] This application provides an eyeglass that is easy to disassemble and install to prevent lens breakage, including a frame, lenses, temples, nose pads and hinges. The frame is made of flexible material, and the periphery of the lens or the inner circle of the frame is provided with a groove for fitting the lens to the frame.

[0008] The hinge consists of a hinge body and a reinforcing component. One end is the hinged end, and the other end is the insertion end. The hinged end is hinged to the temple of the eyeglasses, and the insertion end is inserted into the frame through a socket and reinforced by the reinforcing component.

[0009] The plug has a U-shaped structure. The closed end of the plug is inserted into the socket, and the reinforcement is inserted from the inner opening of the plug to strengthen the fit between the plug and the socket.

[0010] The sidewalls of the socket and the outer wall of the plug are both irregularly shaped, and their contours are complementary to achieve a perfect fit.

[0011] The connector also has a pair of outwardly extending overlapping edges for overlapping with the back of the frame when the connector is inserted into the socket.

[0012] The inner wall of the plug end has a protrusion near its opening. The protrusion is used to cooperate with the reinforcement to open the inner cavity of the plug end.

[0013] The reinforcement is a wedge-shaped structure adapted to the inner cavity of the plug end.

[0014] The reinforcement also includes an abutment block fixed at its outer end in the insertion direction. The abutment block is used to abut against the protrusion and the non-closed end of the insertion end respectively to achieve the positioning and fixation of the reinforcement.

[0015] The temple of the glasses is provided with a pair of opposite connecting ears. The temple is movably installed to the hinge end by screws passing through the pair of connecting ears. The hinge end is provided with a spring piece to improve the deformation resistance of the connection position between the temple and the hinge end.

[0016] One end of the spring is fixedly connected to the inner side of the outer wall of the hinge end, the middle part extends along the outer side of the outer wall of the hinge end, and a deformation gap is reserved between it and the outer wall of the hinge end. The outer side of its outer end can fit against the inner side wall of the temple of the eyeglasses.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The flexible frame material combined with the ring groove fitting structure can buffer the impact of external forces through the deformation of the frame itself, avoiding stress concentration caused by hard contact between the lens and the frame, and reducing the risk of lens breakage from the root; the ring groove fully wraps around the lens, further improving the stability of the lens fixation, preventing edge damage caused by lens displacement and shaking during use, and significantly improving the safety of eyeglasses.

[0019] 2. Convenient and efficient installation and disassembly, with enhanced adaptability. Lenses and frames are directly fitted together via a ring groove, requiring no screws or special tools. Lens installation and replacement can be completed manually, making operation simple and quick. The hinge uses a mating structure between the plug-in end and the frame's insertion hole. Combined with the elasticity of the plug-in end, it enables rapid assembly of the hinge and frame, significantly improving production assembly efficiency. Simultaneously, the flexible frame's deformation characteristics allow the ring groove to adapt to lenses of different sizes, broadening the compatibility range and reducing subsequent maintenance costs.

[0020] 3. The connection structure is stable and has excellent anti-loosening and anti-detachment performance. The complementary irregular structure of the socket and the plug end, the interference fit of the wedge-shaped reinforcement and the protrusion, and the positioning function of the abutment block form a multi-locking mechanism to ensure that the hinge and the frame are firmly connected and avoid loosening or falling off due to long-term use or external impact. The stable hinge fit between the temple and the hinge end further improves the reliability of the overall structure of the glasses, taking into account both convenience and stability.

[0021] 4. Balancing wearing comfort and durability: The flexible frame can adapt to changes in shape when it fits the face, reducing pressure on the face and improving wearing comfort; the spring structure and sleeve design at the hinge end not only buffers the stress when the temples rotate, but also reduces component wear and extends the service life of the glasses, thus satisfying multiple needs of "safety, convenience, comfort and durability".

[0029] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The following description, in conjunction with the accompanying drawings, details a pair of easily detachable glasses designed to prevent lens breakage, provided by the embodiments of this application, through specific examples and application scenarios.

[0032] Example 1:

[0033] This application provides an easy-to-disassemble eyeglass that prevents lens breakage, including a frame 1, a lens 2, temples 3, nose pads 4, and hinges 5. The frame 1 is made of flexible material, and the periphery of the lens 2 or the inner circle of the frame 1 is provided with an annular groove 6 for fitting the lens 2 and the frame 1 together.

[0034] In this embodiment of the application, the annular groove 6 is formed around the lens 2.

[0035] like Figures 1 to 5 As shown, due to the aforementioned structure, the flexible frame 1 can adapt to lenses 2 of different sizes through its own deformation, improving the flexibility of the fit between the frame 1 and the lens 2. The ring groove 6 enables the lens 2 to form a precise fit with the frame 1, ensuring the stability of the lens 2 after installation, effectively preventing the lens 2 from falling off during use, and simplifying the installation and removal of the lens 2, making it easier for later maintenance and replacement. At the same time, the flexible frame 1 (such as silicone or rubber) combined with the fitting structure of the ring groove 6 can also buffer stress through deformation when subjected to external impact, reducing direct damage to the lens 2 and extending the service life of the glasses.

[0036] Example 2:

[0037] In this embodiment, in addition to the structural features of the aforementioned embodiments, the hinge 5 includes a hinge body 51 and a reinforcing member 52, one end of which is a hinge end 511 and the other end is a plug end 512. The hinge end 511 is hinged to the temple 3, and the plug end 512 is plugged into the frame 1 through a socket 513 and reinforced by the reinforcing member 52.

[0038] In this embodiment of the application, the plug end 512 has a U-shaped structure. The closed end of the plug end 512 is inserted into the socket 513, and the reinforcement part 52 is inserted from the inner cavity opening of the plug end 512 to strengthen the fit between the plug end 512 and the socket 513.

[0039] The plug end 512 is also provided with a pair of outwardly extending overlapping edges 514 for overlapping with the back of the frame 1 when the plug end 512 is inserted into the socket 513.

[0040] The back of the frame 1 has an overlap groove 515 corresponding to the overlap edge 514.

[0041] The opening of the plug terminal 512 can face the inside of the frame 1 or the outside of the frame 1.

[0042] like Figures 1 to 5 As shown, due to the above structure, the hinge end 511 of the hinge 5 is flexibly hinged to the temple 3, which can smoothly realize the opening and closing action when wearing glasses and meet the needs of daily use; when the U-shaped plug end 512 is inserted into the plug hole 513 of the frame 1, its opening can face the inside or outside of the frame 1, and the overlapping edge 514 is precisely matched and tightly overlapped with the overlapping groove 515 on the back of the frame 1, which not only realizes the quick positioning of the plug end 512, but also increases the connection stability through surface contact and prevents the plug end 512 from shifting or shaking.

[0043] By utilizing the elastic deformation characteristics of the plug end 512, the plug end 512 can be quickly inserted into the socket 513 to complete the initial fixation without complicated tools, greatly improving the ease of assembly. After the reinforcement part 52 is inserted from the inner cavity opening of the plug end 512, it can expand the U-shaped plug end 512 outward, further tightening the fit gap with the socket 513, forming a dual fixing effect of "positioning + interference locking", which significantly enhances the connection between the hinge 5 and the frame 1 and avoids loosening caused by long-term use or external impact.

[0044] Meanwhile, the separate design of the plug end 512 and the reinforcement part 52 not only facilitates efficient assembly during the production stage, but also allows for easy separation of the hinge 5 and the frame 1 by simply pulling out the reinforcement part 52 if disassembly and maintenance are required later. The operation is simple and quick, perfectly meeting the core requirement of "convenient disassembly and assembly", and taking into account both connection stability and usage flexibility.

[0045] Example 3:

[0046] In this embodiment, in addition to the structural features of the aforementioned embodiments, the sidewall of the socket 513 and the outer wall of the plug end 512 are both irregular structures, and their contour shapes are complementary to achieve mutual fitting.

[0047] In this embodiment of the application, the sidewall of the socket 513 and the outer wall of the plug end 512 are both fitted with a wave-shaped structure.

[0048] like Figures 3 to 5 As shown, due to the above-mentioned structure, the irregular complementary structure (such as wave shape) of the socket 513 and the insertion end 512 can significantly increase the contact area and mechanical engagement point of the two. This can not only effectively limit the relative rotation and axial displacement of the insertion end 512 in the socket 513, thus improving the overall stability of the connection between the hinge 5 and the frame 1, but also disperse the stress at the connection position through the concave and convex fit of the wave-shaped contour, reducing local wear and avoiding structural fatigue caused by long-term stress concentration, thus further extending the connection life of the hinge 5 and the frame 1.

[0049] Example 4:

[0050] In this embodiment, in addition to the structural features of the aforementioned embodiments, a protrusion 7 is provided on the inner sidewall of the plug-in end 512 near its opening. The protrusion 7 is used to cooperate with the reinforcement 52 to open the inner cavity of the plug-in end 512.

[0051] In this embodiment of the application, the reinforcement 52 is a wedge-shaped structure adapted to the inner cavity of the plug end 512.

[0052] like Figures 3 to 5 As shown, due to the above structure, when the wedge-shaped reinforcement 52 is inserted into the inner cavity of the insertion end 512, its inclined surface will form a pressing fit with the protrusion 7 on the inner sidewall of the insertion end 512, forcing the opening of the insertion end 512 to open outward, so that the outer wall of the insertion end 512 and the inner wall of the insertion hole 513 are tightly fitted. Thus, the locking force of the two is further enhanced through the interference fit, effectively preventing the insertion end 512 and the insertion hole 513 from loosening or falling off. At the same time, the limiting effect of the protrusion 7 on the reinforcement 52 can ensure the stability of the opening effect of the wedge structure and avoid the locking failure caused by the force displacement of the reinforcement 52.

[0053] Example 5:

[0054] In this embodiment, in addition to the structural features of the aforementioned embodiments, the reinforcement 52 also includes an abutment block 8 fixed at its outer end in the insertion direction. The abutment block 8 is used to abut against the protrusion 7 and the non-closed end of the insertion end 512 respectively, so as to achieve the positioning and fixing of the reinforcement 52.

[0055] like Figures 3 to 5As shown, due to the above structure, the abutment block 8 at the outer end of the reinforcement 52 can form a tight fit with the protrusion 7 and the non-closed end of the insertion end 512 after the reinforcement 52 is inserted into place. On the one hand, it restricts the over-insertion of the reinforcement 52 and ensures that it is in the optimal open position. On the other hand, the bidirectional tightness realizes the axial positioning of the reinforcement 52 itself, preventing the reinforcement 52 from loosening or falling out due to external forces such as vibration and collision during use. Thus, the reliability and stability of the connection structure are further improved on the basis of embodiment 4.

[0056] Example 6:

[0057] In this embodiment, in addition to the structural features of the aforementioned embodiments, the temple 3 is provided with a pair of oppositely arranged connecting ears 9. The temple 3 is movably mounted to the hinge end 511 by screws passing through the pair of connecting ears 9. The hinge end 511 is provided with a spring piece 10 to improve the deformation resistance of the connection position between the temple 3 and the hinge end 511.

[0058] In this embodiment of the application, one end of the spring piece 10 is fixedly connected to the inner side of the outer wall of the hinge end 511, the middle part extends along the outer side of the outer wall of the hinge end 511, and a deformation gap is reserved between it and the outer wall of the hinge end 511, and the outer side of its outer end can fit against the inner side wall of the eyeglass temple 3.

[0059] In this embodiment of the application, sleeves 11 are provided between the top and bottom surfaces of the hinge end 511 and the connecting ears 9 on both sides.

[0060] like Figures 3 to 5 As shown, due to the above structure, a pair of oppositely arranged connecting ears 9, together with screws, enable flexible hinge connection between the temple 3 and the hinge end 511, ensuring smooth opening and closing of the temple 3. During the rotation of the temple 3, the outer side of the spring piece 10 on the hinge end 511 can elastically fit against the inner wall of the temple 3. The deformation of the spring piece 10 buffers the stress at the connection position, effectively improving the deformation resistance of this part and avoiding breakage at the connection due to long-term opening and closing. At the same time, the sleeve 11 between the top and bottom surfaces of the hinge end 511 and the connecting ears 9 can reduce the direct friction between the two and reduce wear, ensuring smooth rotation and extending the service life of the hinge structure.
