Description

Technical Field

[0001] The utility model relates to a pair of glasses with a screwless hinge structure, belonging to the field of glasses. Background Art

[0002] The connection between the temple and the glasses (or more precisely, the front of the glasses) is achieved by a hinge that connects the front of the glasses to one end of the temple. The connection between the front and the temple by the hinge usually requires the use of small parts, such as screws, bushings, rivets, etc., which enable this connection to be made.

[0003] The use of screws often poses a problem if the user has to remove the temples, as this often requires the assistance of a professional optician. Furthermore, these components can wear out and potentially be lost by the user. The connection between the temples and the front of the glasses can also be fragile, as the hinge is a component that is often subjected to significant stress after repeated opening and closing of the hinge and excessive extension of the temple outside the front of the glasses.

[0004] Therefore, the connection between the temples and lenses of glasses requires a structure that is more convenient to assemble. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide glasses with a screwless hinge structure.

[0006] A pair of glasses with a screwless hinge structure includes a frame, wherein the frame and the temple are connected by a screwless hinge structure, and the screwless hinge structure includes a first connecting arm provided on the temple and a second connecting arm provided on the frame, and a connecting piece is provided between the first connecting arm and the second connecting arm for cooperation between the two so that the frame and the temple are rotatably connected. The design of the screwless hinge reduces the screws and nuts commonly found in traditional glasses, making the overall structure of the glasses simpler, which can also reduce complexity during the production and assembly process. The screwless hinge structure usually uses fewer metal parts, which reduces the weight of the glasses, eliminates the loosening and wear that may be caused by screws, and reduces the risk of failure of the connection accessories between the temple and the frame due to loose screws.

[0007] Preferably, mounting grooves are symmetrically provided on both sides of the connecting member, a first slot for plugging with the connecting member is provided in the first connecting arm, a connecting block is provided in the first slot, and the temples include a first state and a second state. In the first state of the temples, the first connecting arm and the second connecting arm are in a vertical state relative to each other, so that the connecting block enters the mounting groove and then switches to the second state; in the second state of the temples, the first connecting arm and the second connecting arm are in a horizontally connected state, so that the temples and the frame can be rotatably connected in the horizontal direction. The cooperation between the connecting block and the mounting groove provides a stable connection, so that the temples are not easy to fall off or loosen during use. By switching from the first state to the second state, the temples can be conveniently installed on the frame without falling off, and then folded horizontally to ensure normal use.

[0008] Furthermore, the mounting slot includes an inlet channel connected to the outside and a retaining slot connected to the inlet channel. In the second state, the connecting block abuts the bottom of the retaining slot, preventing the temple from dislodging from the frame during rotation. The retaining slot design ensures that the connecting block firmly abuts the bottom of the retaining slot in the second state, significantly enhancing the stability of the connection between the temple and the frame and preventing the temple from loosening or falling off due to accidental collisions during daily use. This abutment and restraint reduces friction and wear at the hinge, extending the service life of the temple and the connecting device.

[0009] Furthermore, the retaining groove includes a first groove and a second groove arranged at an angle. The inlet channel is provided on one side of the first groove, and the connecting block abuts against the bottom of the first groove in the second state. The inclined design of the first groove increases the contact area, thereby strengthening the contact between the connecting block and the groove bottom. The inclined first groove can effectively guide the connecting block during the entry and fixation process, ensuring that the connecting block can be accurately and smoothly positioned.

[0010] Furthermore, the connecting block abuts against the second groove when the temples are folded outward. This contact creates a physical constraint, ensuring the temples are securely fixed when folded outward, preventing accidental opening or movement of the temples under external forces and improving the stability of the overall structure. When the user folds the temples, they can sense the contact position of the connecting block and the second groove, ensuring the temples are correctly placed, thus avoiding the inconvenience caused by improper positioning when storing or wearing the temples.

[0011] Preferably, the second connecting arm is provided with a second slot for connecting with the connector. An extension extending to one side of the connector is provided on one side of the second slot, and a positioning slot is provided at the bottom of the extension. The first connecting arm is provided with a positioning post that slidably connects with the positioning slot in the second state. The design of the second slot and the extension further stabilizes the connection between the connector and the first connecting arm. The extension provides additional support, ensuring that the connection is not easily loosened during use, thereby improving the stability of the overall structure. The positioning slot at the bottom of the extension allows the positioning post to accurately enter and effectively position the connector. This design ensures a clear relative position between the connector and the temple in the second state, improving the accuracy of the fit.

[0012] Furthermore, the mounting slots are located on the upper and lower sides of the connector, while the positioning slots are located on the side of the connector. Providing positioning slots on the side of the connector and distributing the mounting slots up and down helps maintain a compact structure. This provides more support contact points, helping to improve the stability of the connection.

[0013] Furthermore, outwardly extending docking plates are provided on either side of the openings of the first and second slots, and the docking plates are arranged at an angle. The inclined docking plate design increases the contact area with the connector, improving the stability and firmness of the connection. This larger contact area effectively disperses the forces applied to the connection, reducing stress concentration. The inclined docking plates provide better support after the connector is plugged in, helping to lock the connector in place and prevent it from shifting or loosening when subjected to external forces, thereby improving the safety of the overall structure.

[0014] Preferably, connecting arms are extended from the bottom of the first connecting arm and the second connecting arm, and the connecting arms are respectively positioned and fixedly connected to the temples and the frame through pins.

[0015] The beneficial effects of this invention are as follows: The screwless hinge design eliminates the screws and nuts commonly found in traditional eyewear, making the overall structure of the eyewear more concise, which also reduces complexity during production and assembly. The screwless hinge structure generally uses fewer metal components, reducing the weight of the eyewear, eliminating the potential loosening and wear caused by screws, and reducing the risk of failure of the temple-frame connection due to loose screws.

[0026] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0027] like Figure 1-6As shown, an embodiment of the glasses with a screwless hinge structure of the present invention comprises a frame 1, wherein the frame 1 is connected to the temple 2 via a screwless hinge structure, and the screwless hinge structure comprises a first connecting arm 363 provided on the temple 2 and a second connecting arm 436 provided on the frame 1, and a connecting member 5 is provided between the first connecting arm 363 and the second connecting arm 436 for cooperation between the two so that the frame 1 and the temple 2 are rotatably connected. The design of the screwless hinge reduces the screws and nuts commonly found in traditional glasses, making the overall structure of the glasses simpler, which can also reduce complexity during the production and assembly process. The screwless hinge structure generally uses fewer metal parts, which reduces the weight of the glasses, eliminates the loosening and wear that may be caused by screws, and reduces the risk of failure of the connection accessories between the temple 2 and the frame 1 due to loose screws.

[0028] The connector 5 is symmetrically provided with mounting grooves 51 on both sides. The first connecting arm 363 is provided with a first slot 31 for plugging with the connector 5. The first slot 31 is provided with a connecting block 32. The temple 2 includes a first state and a second state. In the first state, the first connecting arm 363 and the second connecting arm 436 are vertical to each other, so that the connecting block 32 enters the mounting groove 51 and switches to the second state. In the second state, the first connecting arm 363 and the second connecting arm 436 are horizontally connected, so that the temple 2 can be rotatably connected to the frame 1 in the horizontal direction. The cooperation between the connecting block 32 and the mounting groove 51 provides a stable connection, so that the temple 2 is not easy to fall off or loosen during use. By switching from the first state to the second state, the temple 2 can be easily installed on the frame 1 without falling off, and then folded horizontally to ensure normal use.

[0029] The mounting slot 51 includes an inlet channel 52 communicating with the exterior and a retaining slot 53 communicating with the inlet channel 52. In the second state, the connecting block 32 abuts against the bottom of the retaining slot 53, preventing the temple 2 from dislodging from the frame 1 during rotation. The design of the retaining slot 53 ensures that the connecting block 32 firmly abuts against the bottom of the retaining slot 53 in the second state, significantly enhancing the stability of the connection between the temple 2 and the frame 1 and preventing the temple 2 from loosening or falling off due to accidental collisions during daily use. This abutment and restraint reduces friction and wear at the hinge, extending the service life of the temple 2 and the connecting device.

[0030] Furthermore, the limiting groove 53 includes a first groove 54 and a second groove 55 arranged at an angle. The inlet channel 52 is provided on one side of the first groove 54. In the second state, the connecting block 32 abuts against the bottom of the first groove 54. The inclined design of the first groove 54 increases the contact area, thereby strengthening the contact between the connecting block 32 and the groove bottom. The inclined first groove 54 effectively guides the connecting block 32 during the insertion and fixation process, ensuring that the connecting block 32 can be accurately and smoothly positioned.

[0031] When the temple 2 is folded outward, the connecting block 32 abuts against the second groove 55 to limit its position. This abutment between the connecting block 32 and the second groove 55 creates a physical restraint, ensuring that the temple 2 is securely fixed when folded outward, preventing accidental opening or movement of the temple 2 under external forces and improving the stability of the overall structure. When the user folds the temple 2, they can sense the abutment between the connecting block 32 and the second groove 55, ensuring the temple 2 is correctly placed, thus avoiding the inconvenience caused by improper positioning when storing or wearing the temple.

[0032] The second connecting arm 436 is provided with a second slot 41 for connecting with the connector 5. An extension 42 is provided on one side of the second slot 41, extending to the side of the connector 5. A positioning slot 43 is provided at the bottom of the extension 42. The first connecting arm 363 is provided with a positioning post 33 that slidably engages with the positioning slot 43 in the second state. The design of the second slot 41 and the extension 42 further stabilizes the connection between the connector 5 and the first connecting arm 363. The extension 42 provides additional support, ensuring that the connection is not easily loosened during use, thereby enhancing the stability of the overall structure. The positioning slot 43 at the bottom of the extension 42 allows the positioning post 33 to accurately enter and effectively position the connector 5. This design ensures a clear relative position between the connector 5 and the temple 2 in the second state, improving the accuracy of the fit.

[0033] Mounting slots 51 are located on the top and bottom of connector 5, while positioning slots 43 are located on the side of connector 5. Providing positioning slots 43 on the side of connector 5 and distributing mounting slots 51 vertically helps maintain a compact structure, providing more support contact points and improving connection stability.

[0034] Outwardly extending docking plates 34 are provided on either side of the openings of the first and second slots 31, 41. These docking plates 34 are arranged at an angle. The angled design of the docking plates 34 increases the contact area with the connector 5, enhancing the stability and robustness of the connection. This larger contact area effectively disperses the forces applied to the connection, reducing stress concentration. The angled docking plates 34 provide better support after the connector 5 is inserted, helping to lock the connector 5 in place and prevent it from shifting or loosening when subjected to external forces, thereby improving the safety of the overall structure.

[0035] A connecting arm 36 extends from the bottom of the first connecting arm 363 and the second connecting arm 436 , and the connecting arm 36 is respectively positioned and fixedly connected to the temple 2 and the frame 1 through a pin 35 .

[0036] When in use, the first connecting arm 363 and the second connecting arm 436 are respectively installed on the temple 2 and the frame 1, and then the connecting member 5 is inserted into the second slot 41 of the second connecting arm 436 to assemble the temple 2.

[0037] When connecting the temple 2, the connecting block 32 is connected to the connecting member 5 through the inlet channel 52 of the mounting groove 51. At this time, the first connecting arm 363 and the second connecting arm 436 are in a vertical state relative to each other. Then the first connecting arm 363 is rotated with the connecting block 32 as the rotation center, so that the first connecting arm 363 and the second connecting arm 436 are docked and located on the same horizontal line. This is the second state.

[0038] In the second state, the first connecting arm 363 can be folded outward, and at the same time, it is limited by the limiting groove 53 and will not be excessively turned outward, so as to adapt to the face shapes of different people. In the normal state, it is limited by the first groove 54 and will not easily fall out, causing the connection structure to fail.

[0039] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.

[0040] Although the present invention has been described with reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed, and the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
