Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, specifically to an eyeglass with a hinge structure that prevents breakage. Background Technology

[0002] This utility model relates to the field of eyeglasses technology, and in particular to an eyeglass with a break-proof damping hinge structure and a detachable nose pad.

[0003] As a commonly used vision correction and fashion accessory, the hinge structure between the temples and the frame of eyeglasses directly affects the user experience and lifespan. Currently, traditional eyeglass hinges mostly use a simple screw-shaft structure, which has problems such as uneven damping, inability to stop at any angle, easy breakage when forcibly bent, and screws that are prone to loosening and falling off after long-term use.

[0004] In the prior art, Chinese utility model patent CN221726329U discloses a type of eyeglasses with a novel temple connection structure. This structure provides rotational damping by setting a damping bearing seat and a damping rod wrapped with a rubber membrane on an extension plate, and limits the maximum opening of the temples by a limiting block. However, this technical solution has the following drawbacks:

[0005] 1. Lack of overload protection mechanism; when the user accidentally forces the temple of the glasses to open beyond the maximum opening, the hinge structure is prone to brittle fracture.

[0006] 2. No anti-loosening measures are installed on the screws. During long-term use, the screws are prone to loosening or even falling off due to vibration, which will affect the normal use of the glasses.

[0007] 3. The nose pad has a simple structure, making it prone to rotation and detachment. Furthermore, it is difficult to replace the damaged pad individually, making maintenance inconvenient. Utility Model Content

[0008] This utility model aims to solve one of the technical problems existing in the prior art.

[0009] This application provides an eyeglass with a non-breakable hinge structure, including an eyeglass frame, a pair of temples and a pair of nose pads. The temples include a connecting section, an ear loop section and a hinge shell. Deformation grooves are provided on the inner sides of the upper and lower surfaces of the hinge shell. The deformation grooves divide the hinge shell into two parts. One part of the hinge shell is fixedly connected to the ear loop section, and the other part is hinged to the connecting section by fasteners. The other part of the connecting section is fixedly connected to the eyeglass frame by fasteners.

[0010] Furthermore, the deformation groove is semi-circular with one end open, and the open section of the deformation groove is located on the side of the hinge shell away from the eyeglass frame, facing outwards.

[0011] Furthermore, the fastener is a screw that passes through the connection point between the connecting section and the temple or hinge shell from bottom to top, with a screw hole at the top and a through hole at the bottom.

[0012] Furthermore, it also includes lacquer, which is dripped onto the top of the screw to seal the upper end of the screw hole and fill the gap between the screw hole and the screw.

[0013] Furthermore, a rectangular connecting ear is fixed on the eyeglass frame, and a rectangular connecting groove is opened on the bottom surface of one end of the connecting section. After the rectangular connecting ear and the rectangular connecting groove are fitted together, they are tightened and fixed by fasteners.

[0014] Furthermore, a circular connecting ear is fixed at the end of the connecting section away from the eyeglass frame, and a circular connecting groove is opened on the side wall of the hinge shell. The circular connecting ear is inserted into the circular connecting groove, and the fastener passes through the circular connecting groove along the central axis of the hinge shell and is tightened to fix it. The circular connecting ear and the fastener form a rotational engagement.

[0015] Furthermore, the nose pad includes a connecting arm and a nose pad leaf. One end of the connecting arm is fixed to the eyeglass frame via a plug-in unit, and the other end is fixed with an elliptical connecting ring. The peripheral wall of the nose pad is provided with a ring groove for fitting into the inner ring of the connecting ring.

[0016] Furthermore, the plug-in unit includes a connecting rod and a pair of plug rods. The connecting rod is vertically arranged and its middle part is fixedly connected to the end of the connecting arm away from the connecting ring. The pair of plug rods are respectively fixed at the upper and lower ends of the connecting rod and are perpendicular to the connecting rod. The eyeglass frame has a plug hole that is interference-fitted with the plug rod.

[0017] Furthermore, the nose pad also includes an anti-detachment rod and an anti-detachment groove. One end of the anti-detachment rod is fixed in the inner ring of the connecting ring, and the anti-detachment groove is opened in the ring groove and extends towards the center of the nose pad.

[0018] Furthermore, the width of both the free end of the anti-detachment rod and the inner end of the anti-detachment groove is greater than that of the other end.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By opening semi-circular open deformation grooves on the inner side of the upper and lower surfaces of the hinge shell, the shells on both sides of the deformation groove will generate inward elastic pre-deformation when the screw is tightened, so that the hinge shell and the hinge surface of the connecting section are tightly fitted to generate a uniform and stable damping torque. The eyeglass temple can be suspended and positioned at any angle within the normal opening and closing range without the need for additional damping components. At the same time, the deformation groove can generate controllable elastic opening deformation when the lug section is subjected to overload force, absorb the overload impact force, avoid the hinge structure from breaking, and automatically reset itself by its own elasticity after the external force is removed.

[0021] 2. By using a screw inserted from bottom to top, along with the lacquer dripped from the top, the opening at the top of the screw hole is sealed and the gap between the screw hole and the screw thread is filled. This prevents the screw from loosening and falling off due to vibration during long-term use, while also ensuring a clean appearance without screw heads on the outer surface of the glasses.

[0022] 3. The elliptical connecting ring and the groove on the periphery of the nose pad achieve complete circumferential positioning, preventing the nose pad from rotating relative to the connecting arm. The anti-detachment rod at the widened end of the connecting ring and the anti-detachment groove at the widened end of the nose pad groove interlock to form a secondary anti-detachment structure, effectively preventing the nose pad from falling out. At the same time, the connecting arm is fixed to the eyeglass frame by a double-insertion rod interference fit, realizing quick assembly of the nose pad and convenient replacement of the nose pad.

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.

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 glasses provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0032] Example 1:

[0033] This application provides an eyeglass with a non-breakable hinge structure, including an eyeglass frame 1, a pair of temples 2 and a pair of nose pads 3. The temples 2 include a connecting section 21, an ear loop section 22 and a hinge shell 23. Deformation grooves 24 are provided on the inner sides of the upper and lower surfaces of the hinge shell 23. The deformation grooves 24 divide the hinge shell 23 into two parts. One part of the hinge shell 23 is fixedly connected to the ear loop section 22, and the other part is hinged to the connecting section 21 by fasteners 25. The other part of the connecting section 21 is fixedly connected to the eyeglass frame 1 by fasteners 25.

[0034] In this embodiment of the application, the deformation groove 24 is semi-circular and open at one end, and the open section of the deformation groove 24 is located on the outward side of the hinge shell 23 away from the eyeglass frame 1.

[0035] In this embodiment of the application, the fastener 25 is a screw that passes through the connection position between the connecting section 21 and the temple 2 or the hinge shell 23 from bottom to top. The upper end of the connection position is a screw hole and the lower end is a through hole.

[0036] In this embodiment of the application, lacquer 26 is also included, which is dripped onto the upper end of the screw to seal the upper end of the screw hole and fill the gap between the screw hole and the screw.

[0037] like Figures 1 to 3 As shown, due to the above structure, during assembly, the first screw is inserted from bottom to top into the connection position between the connecting section 21 and the eyeglass frame 1. The lower end of this connection position is a through hole and the upper end is a screw hole. After tightening the screw, the connecting section 21 and the eyeglass frame 1 can be firmly fixed together. Then, the second screw is inserted from bottom to top into the hinge position between the hinge shell 23 and the connecting section 21. This hinge position also adopts the structure of a through hole at the lower end and a screw hole at the upper end. As the screw is gradually tightened, the two sides of the semi-circular deformation groove 24 on the inner side of the upper and lower surfaces of the hinge shell 23 will produce inward elastic pre-deformation, so that the upper and lower hinge surfaces of the hinge shell 23 and the connecting section 21 fit tightly together. Finally, lacquer 26 is dripped onto the upper end of the two screws to seal the upper opening of the screw hole and fill the gap between the screw hole and the screw thread, preventing the screw from loosening and falling off due to vibration during long-term use.

[0038] When in use, when an external force causes the ear loop section 22 to rotate within the normal opening and closing range, the ear loop section 22 will drive the hinge shell 23, which is fixed to it, to rotate synchronously around the screw axis. Due to the continuous clamping force generated by the pre-deformation of the deformation groove 24, a uniform and stable damping torque will be generated between the hinge shell 23 and the hinge surface of the connecting section 21, which will counteract the influence of the weight of the temple 2 itself, and realize the suspension and positioning of the temple 2 at any angle within the normal opening and closing range. The fit when wearing and the convenience when taking off can be guaranteed without the need for additional damping components.

[0039] When the ear loop 22 rotates to the designed maximum opening position, the limiting end face of the hinge shell 23 will abut against the corresponding limiting end face of the connecting section 21, forming a rigid limit to prevent it from continuing to rotate normally. If a bending force is applied outward at this time, since the open section of the deformation groove 24 is located on the outward side of the hinge shell 23 away from the eyeglass frame 1, the overload external force will directly act on the open end of the deformation groove 24, causing the deformation groove 24 to produce controllable elastic opening deformation, allowing the ear loop 22 to deflect outward moderately on the basis of the maximum opening, thereby absorbing the overload impact force and preventing the hinge structure from breaking due to the user forcibly bending the temple 2 during wearing. After the external force is removed, the deformation groove 24 automatically resets based on the elastic properties of its own material, driving the ear loop 22 to accurately return to the designed maximum opening position without permanent plastic deformation.

[0040] Example 2:

[0041] In this embodiment, in addition to the structural features of the aforementioned embodiments, a rectangular connecting ear is fixed on the eyeglass frame 1, and a rectangular connecting groove is opened on the bottom surface of one end of the connecting segment 21. After the rectangular connecting ear and the rectangular connecting groove are fitted together, they are tightened and fixed by fasteners 25.

[0042] like Figures 1 to 3 As shown, due to the above structure, during assembly, the rectangular connecting ear on the eyeglass frame 1 is first aligned and embedded into the rectangular connecting groove at the end of the connecting section 21. The connecting section 21 is fully positioned in the circumferential and radial directions relative to the eyeglass frame 1 through the mating surface of the rectangular structure, completely eliminating the relative rotation and wobbling gap between the two. Then, the fastener 25 is vertically inserted through the rectangular connecting groove and the rectangular connecting ear from the top surface of the connecting section 21 and tightened to lock it, so that the connecting section 21 and the eyeglass frame 1 form an irremovable rigid connection.

[0043] Example 3:

[0044] In this embodiment, in addition to the structural features of the aforementioned embodiments, a circular connecting ear is fixedly provided at the end of the connecting segment 21 away from the eyeglass frame 1, a circular connecting groove is provided on the side wall of the hinge shell 23, the circular connecting ear is inserted into the circular connecting groove, and the fastener 25 passes through the circular connecting groove along the central axis of the hinge shell 23 and is screwed in to fix it, and the circular connecting ear and the fastener 25 form a rotational engagement.

[0045] like Figures 1 to 3 As shown, due to the above structure, during assembly, the circular connecting ear at the end of the connecting section 21 is first horizontally inserted into the circular connecting groove on the side wall of the hinge shell 23, so that the center hole of the circular connecting ear is automatically aligned with the central axis of the hinge shell 23. Then, the fastener 25 is inserted into the circular connecting groove from the outside along the central axis of the hinge shell 23, passes through the center hole of the circular connecting ear, and is tightened and fixed in the internal thread hole of the hinge shell 23. During operation, the fastener 25 remains stationary, and the circular connecting ear can rotate freely around the axis of the smooth section of the fastener 25, realizing the 90° opening and closing action of the eyeglass temple 2 relative to the eyeglass frame 1. At the same time, the inner wall of the circular connecting groove forms an axial limit on the circular connecting ear, effectively preventing the eyeglass temple 2 from axially moving during the opening and closing process.

[0046] Example 4:

[0047] In this embodiment, in addition to the structural features of the aforementioned embodiments, the nose pad 3 includes a connecting arm 31 and a pad 32. One end of the connecting arm 31 is fixed to the eyeglass frame 1 through a plug-in unit 4, and the other end is fixed with an elliptical connecting ring 33. The peripheral wall of the pad 32 is provided with an annular groove for fitting into the inner ring of the connecting ring 33.

[0048] In this embodiment of the application, the plug-in unit 4 includes a connecting rod 41 and a pair of plug rods 42. The connecting rod 41 is vertically arranged and its middle part is fixedly connected to the end of the connecting arm 31 away from the connecting ring 33. The pair of plug rods 42 are respectively fixed at the upper and lower ends of the connecting rod 41 and are perpendicular to the connecting rod 41. The eyeglass frame 1 has a plug hole that is interference-fitted with the plug rod 42.

[0049] In this embodiment of the application, the nose pad 3 further includes an anti-detachment rod 35 and an anti-detachment groove 34. One end of the anti-detachment rod 35 is fixed in the inner ring of the connecting ring 33, and the anti-detachment groove 34 is formed in the ring groove and extends toward the center of the nose pad 32.

[0050] In this embodiment of the application, the width of the free end of the anti-detachment rod 35 and the width of the inner end of the anti-detachment groove 34 are both greater than the other end.

[0051] like Figure 4 As shown, due to the above structure, when assembling the nose pad 3, firstly, align the two insertion rods 42 of the insertion unit 4 with the corresponding two insertion holes on the eyeglass frame 1, apply axial pressure to make the insertion rods 42 and the insertion holes form an interference fit, then first insert the anti-dislodgement rod 35 of the inner ring of the connecting ring 33 into the anti-dislodgement groove 34 of the nose pad 32, and then press the nose pad 32 along the extension direction of the anti-dislodgement rod 35 so that the elliptical connecting ring 33 is completely embedded in the annular groove of the nose pad 32, thus completing the assembly of the nose pad 32 and the connecting arm 31.

[0052] In use, the mating surfaces of the elliptical connecting ring 33 and the elliptical support leaf 32 form a circumferentially complete positioning, completely preventing the support leaf 32 from rotating relative to the connecting arm 31. At the same time, since the anti-detachment rod 35 is pre-inserted into the anti-detachment groove 34 and both ends are widened, it can effectively prevent the support leaf 32 from coming out of the connecting ring 33.
