Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyeglasses technology, specifically to an elastic structure for eyeglasses hinges. Background Technology
[0002] In conventional eyeglasses, the temples and frames are usually connected by a post on the frame, with the post and temple connected by a hinge. The post and hinge, and the temple and hinge, are usually fixed by spot welding. Some eyeglasses, to provide some elasticity to the temples when worn, often incorporate a V-shaped spring or spring plate between the hinges. This allows for adaptive adjustment of the clamp between the temples within a certain range, enhancing wearing comfort. However, this spring-based method often results in hair getting caught, and it's also difficult to assemble. Using spring plates... The elastic structure is achieved either by spot welding to fix the spring or by integral molding. When spot welding the spring, the material of the spring does not need to be the same as that of the temple or post. However, the spot welding connection is often not strong due to the different materials of the spot welding objects, which seriously shortens the service life of the glasses. On the other hand, the integral molding method restricts the selection of spring materials, resulting in either unsatisfactory elasticity or a sharp increase in production costs. Moreover, once the elastic structure of glasses made by the above methods is damaged, it needs to be replaced and repaired. It cannot be disassembled for repair, resulting in high repair costs. Utility Model Content
[0003] The purpose of this utility model is to provide a flexible structure for the hinge position of eyeglasses. One end of the flexible component is hinged to the stud, and the other end is detachably connected to the temple. This structure is not only easy to assemble, but also the material selection of the flexible component is not restricted by the stud or temple. The flexible component can be flexibly made of materials with corresponding properties according to actual needs. This helps to reduce production difficulty and production cost while meeting the requirements, and solves the problems in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible hinge structure for eyeglasses, comprising a post fixedly connected to the frame and a temple rotatably connected to the post. The post and temple are integrally elastically connected by a flexible element. The flexible element includes a fastening part and a flexible part. One end of the flexible part is fixedly connected to the fastening part, and the other end is bent to form a hinge pawl. The post is provided with a hinge through hole through which the hinge pawl can pass and engage. One end wall of the temple is provided with a flexible element mounting groove. The fastening part is fixed in the flexible element mounting groove. The hinge pawl's latching direction faces the temple wall. An elastic clamp is formed between the flexible part and the temple wall. The hinge pawl is hinged in the hinge through hole. The end of the post located away from the frame from the hinge through hole is a support part. The support part is located in the elastic clamp, and the length of the support part is not less than the width of the elastic clamp.
[0005] Preferably, the elastic element mounting groove is a U-shaped groove, and the U-shaped groove forms a slot with the temple wall. The elastic element fastening part is installed in the elastic element mounting groove by inserting its opposite side edges into the slot.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-8A flexible hinge structure for eyeglasses includes a head 2 fixedly connected to a frame 1 and a temple 3 rotatably connected to the head 2. The head 2 and the temple 3 are integrally elastically connected by a spring element 4. The spring element 4 includes a fastening part 41 and a spring part 42. One end of the spring part 42 is fixedly connected to the fastening part 41, and the other end is bent to form a hinge claw 43. The head 2 is provided with a hinge through hole 21 through which the hinge claw 43 can be engaged. One end wall of the temple 3 is provided with a spring element mounting groove 31. The fastening part 41 is fixedly mounted on the spring element mounting groove 31. Within the mounting groove 31, the elastic element mounting groove 31 is a U-shaped groove, forming a slot 32 between the U-shaped groove and the wall of the temple 3. The fastening part 41 of the elastic element 4 is installed in the elastic element mounting groove 31 by inserting its opposing side edges into the slot 32. A fastening claw 44 is integrally connected to the fastening part 41, and a fastening position 33 is provided on the wall of the temple 3. When the fastening part 41 of the elastic element 4 is installed in the elastic element mounting groove 31, the fastening claw 44 and the fastening position 33 are engaged and connected. The fastening mechanism stabilizes the installation of the elastic element 4 and the temple 3, preventing the temple 3 from detaching from the eyeglasses during use. When it is necessary to remove the elastic element 4 from the elastic element mounting groove 31, a thin tool is used to lift the fastening claw 44 to disengage it from the fastening buckle 33. At this point, the elastic element 4 can be easily pulled out of the elastic element mounting groove 31, completing the removal operation. The hinge claw 43 is positioned with its opening facing the wall of the temple 3. An elastic clamp is formed between the elastic part 42 and the wall of the temple 2. The hinge claw 43 is hinged to the hinge through hole. Within 21, the end of the hinged through hole 21 furthest from the frame 1, where the pile head 2 is located, is a support portion 22. The support portion 22 is positioned within the elastic clamp, and its length is not less than the width of the elastic clamp. When the temple 3 is in an unfolded state relative to the frame 1, the support portion 22 is freely accommodated within the elastic clamp, without any unnecessary constraint on the pile head 2 or the temple 3. When the temple 3 is in a retracted state relative to the frame 1, the support portion 22 rotates 90 degrees and lifts the temple 3. At this time, the elastic part 42 on the elastic element 4 undergoes elastic deformation, causing the elastic clamp to widen. Figure 8 As shown, the elastic clamp forms an elastic clamping force on the expansion part 22, which stabilizes the closed shape of the temple 3. Without sufficient external force to overcome the elastic clamping force, the closed shape of the temple 3 relative to the frame 1 is not changed.
[0022] A contact protrusion 23 is provided on the side wall where the head 2 and temple 3 are in contact. The contact protrusion 23 protrudes from the wall of the head 2. The design of the contact protrusion 23 can not only achieve the contact effect between the head 2 and temple 3, but also minimize the contact area of the contact surface, so as to avoid the phenomenon that the paint peels off a large area due to frequent contact between the head 2 and temple 3, which would damage the appearance of the glasses.
[0023] The temple 3 is provided with a claw clearance hole 34. When the temple 3 is in an unfolded state relative to the frame 1, the axial projection area of the hinge through hole 21 is located within the axial projection area of the claw clearance hole 34. When the temple 3 is in an unfolded state relative to the frame 1, the claw clearance hole 34 allows the end of the hinge claw 43 to extend into and be stored. On the one hand, this reduces the volume occupied by the hinge claw 43 in the elastic clamp, so that the elastic clamp is minimized to better clamp the temple 3, thereby stabilizing the overall frame structure of the eyeglasses. On the other hand, when the hinge claw 43 extends into the claw clearance hole 34, the connection structure between the temple 3 and the post 2 will also be double reinforced.
[0024] In summary: One end of the elastic component 4 is hinged to the head 2, and the other end is detachably connected to the temple 3. This not only makes assembly easy, but also allows the selection of materials for the elastic component 4 to be flexible, without being restricted by the head 2 or the temple 3. Materials with corresponding properties can be flexibly selected to manufacture the elastic component 4 according to actual needs. This helps to reduce production difficulty and costs while meeting the requirements. In addition, the elastic component 4, which exists independently, can be colored in various ways to match the eyeglasses body and create a color-blocking effect, enriching the appearance and color expression of the eyeglasses body. This allows for style diversification on the same product and meets the aesthetic needs of more types of consumers.
