Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyeglasses technology, and in particular to an easy-to-assemble eyeglass frame. Background Technology
[0002] Eyeglass frames typically consist of a rim, hinges, and temples. The rim holds the lenses, the hinges connect the rim and temples and provide elasticity to the temples, ensuring they are securely held on the head, and the temples are connected to the hinges by screws. Traditionally, assembling the temples and hinges requires a specialized screwdriver to precisely screw the screws into the holes. However, this screw-fixing method relies on specialized tools and skilled operators, increasing the number of parts and assembly steps, extending the production cycle. Furthermore, maintenance also requires specialized tools to completely remove the screws, increasing the complexity of maintenance and resulting in poor assembly efficiency and ease of maintenance. Utility Model Content
[0003] Therefore, it is necessary to provide an easy-to-assemble eyeglass frame to address the technical problems of poor assembly efficiency and ease of maintenance.
[0004] An easily assembled eyeglass frame includes a frame, a hinge, and temples. The hinge includes a connecting part connected to the frame, a rotating part connected to the connecting part, and a supporting part connected to the side wall of the rotating part. The rotating part has a rotating hole and a notch communicating with the rotating hole, the notch facing the frame. The temples include a flexible temple body, a locking part, and a limiting part. The flexible temple body is connected to the locking part, the locking part has a movable groove for the rotating part to move through, the limiting part is disposed in the movable groove, the limiting part passes through the notch into the rotating hole, and can rotate along the rotation axis of the rotating hole. The temples have a wearing state and a folded state. In the wearing state, the locking part abuts against the supporting part, limiting the angle at which the temples unfold outward. In the folded state, the temples fold inward, the flexible temple body contacts the frame, and the frame prevents the limiting part from rotating to the position corresponding to the notch.
[0005] During assembly, a force is applied to bend the flexible leg body, causing the limiting part to pass through the notch and enter the rotating hole. After assembly, the force applied to bend the flexible leg body is stopped, and the flexible leg body and the locking part are aligned in a straight line, so that the frame prevents the limiting part from rotating to the position corresponding to the notch.
[0006] In one embodiment, the flexible leg body, the snap-fit portion, and the limiting portion are integrally formed.
[0007] In one embodiment, the temple further includes a guide post, which is rotatably disposed within the rotating hole and has a limiting groove that cooperates with the limiting part.
[0008] In one embodiment, the limiting groove accommodates the limiting portion and part of the snap-fit portion.
[0009] In one embodiment, there are two limiting grooves, which are respectively disposed at opposite ends of the guide post. The number of limiting portions and the number of notches are the same as the number of limiting grooves.
[0010] In one embodiment, the adapter is provided with a slot, and the frame is provided with a groove that engages with the slot.
[0011] In one embodiment, the rotating part is a cylindrical structure, and the notch is a fan-shaped notch opened along the axial direction.
[0012] In one embodiment, the abutment is an annular retaining edge disposed on the side of the rotating part.
[0013] In one embodiment, the flexible leg body is made of one of the following materials: elastic plastic, rubber, or metal.
[0014] In one embodiment, the adapter, the rotating part, and the supporting part are integrally formed.
[0015] The beneficial effects of the easy-to-assemble eyeglass frame provided in this application are as follows: The flexible temple body, with its curved shape, allows the limiting part to pass through a notch into the rotating hole, enabling the assembly of the temple and hinge. This method eliminates the need for specialized tools, requiring only simple operation, effectively improving assembly convenience and reducing assembly difficulty. Furthermore, in the wearing state, the locking part and the supporting part abut against each other, precisely limiting the outward opening angle of the temple, ensuring stability and comfort. In the storage state, the temple folds inward, the flexible temple body contacts the frame, and the frame prevents the limiting part from rotating to the position corresponding to the notch, effectively preventing the temple from detaching from the hinge. When maintenance is required, bending the flexible temple body allows the limiting part to pass through the notch and disengage from the rotating hole, thus separating the hinge and temple. This eliminates the need for specialized tools in assembling and separating the hinge and temple, effectively reducing the assembly and maintenance steps of the eyeglass frame, thereby improving assembly efficiency and maintenance convenience.

[0024] like Figure 1 As shown, it is the easy-to-assemble eyeglass frame 100 of this utility model.
[0025] like Figures 1 to 3As shown, the easy-to-assemble eyeglass frame 100 includes: a frame 10, a hinge 20, and temples 30. The hinge 20 includes a connecting part 21 connecting to the frame 10, a rotating part 22 connected to the connecting part 21, and a supporting part 23 connected to the side wall of the rotating part 22. The rotating part 22 has a rotating hole 221 and a notch 222 communicating with the rotating hole 221. The notch 222 faces the frame 10. The temples 30 include a flexible temple body 31, a locking part 32, and a limiting part 33. The flexible temple body 31 is connected to the locking part 32, and the locking part 32 is provided for rotation. The movable groove 321 of the part 22 is movably inserted, and the limiting part 33 is disposed in the movable groove 321. The limiting part 33 passes through the notch 222 and enters the rotating hole 221, and can rotate along the rotation axis of the rotating hole 221. The temple 30 has a wearing state and a storage state. When it is in the wearing state, the locking part 32 abuts against the supporting part 23, limiting the angle at which the temple 30 unfolds outward. When it is in the storage state, the temple 30 folds inward, and the flexible temple body 31 contacts the frame 10. The frame 10 prevents the limiting part 33 from rotating to the position corresponding to the notch 222.
[0026] During assembly, a force is applied to bend the flexible temple 31, allowing the limiting part 33 to pass through the notch 222 and enter the rotating hole 221. After assembly, the force applied to bend the flexible temple 31 is stopped, and the flexible temple 31 and the locking part 32 are aligned. This prevents the limiting part 33 from rotating to the position corresponding to the notch 222 by the frame 10. During maintenance, bending the flexible temple 31 of the temple 30 allows the limiting part 33 to pass through the notch 222 and disengage from the rotating hole 221, thus separating the hinge 20 from the temple 30. By using the method of bending the flexible temple 31 of the temple 30 to allow the limiting part 33 to pass through the notch 222 and enter the rotating hole 221 to assemble the temple 30 and hinge 20, the eyeglass frame assembly process can be completed without professional tools, requiring only simple operation, effectively improving the convenience of assembly. The design facilitates easy assembly and reduces assembly difficulty. When worn, the locking part 32 and the supporting part 23 abut against each other, precisely limiting the outward opening angle of the temple 30 to ensure stability and comfort. When stored, the temple 30 folds inward, and the flexible temple body 31 contacts the frame 10. The frame 10 prevents the limiting part 33 from rotating to the position corresponding to the notch 222, effectively preventing the temple 30 from detaching from the hinge 20. When maintenance is required, bending the flexible temple body 31 of the temple 30 allows the limiting part 33 to pass through the notch 222 and disengage from the rotation hole 221, thus separating the hinge 20 and the temple 30. This allows the assembly and separation of the hinge 20 and the temple 30 to be done without the aid of professional tools, thereby effectively reducing the assembly and maintenance procedures of the eyeglass frame and improving the assembly efficiency and maintenance convenience of the eyeglass frame.
[0027] The following text, combined with Figures 1 to 4 Further explanation is provided regarding the aforementioned easy-to-assemble eyeglass frame 100.
[0028] To reduce the production cost of hinge 20, such as Figures 3 to 4 As shown, the adapter 21, rotating part 22 and supporting part 23 are integrally formed. The integrally formed adapter 21, rotating part 22 and supporting part 23 increase the processing convenience of hinge 20, which can effectively reduce the processing time and production cycle of hinge 20, thereby reducing the production cost of hinge 20.
[0029] To reduce the production cost of temple 30, such as Figure 3 As shown, the flexible temple body 31, the snap-fit part 32, and the limiting part 33 are integrally formed. The flexible temple body 31, the snap-fit part 32, and the limiting part 33 can be formed by laser cutting of metal sheets. The integrally formed flexible temple body 31, the snap-fit part 32, and the limiting part 33 increase the processing convenience of the temple 30, reduce the processing time and production cycle of the temple 30, and achieve the purpose of effectively reducing the production cost of the temple 30.
[0030] like Figures 2 to 3 As shown, the temple 30 also includes a guide post 34, which is rotatably disposed in the rotating hole 221 and is provided with a limiting groove 341 that cooperates with the limiting part 33. By providing a limiting groove 341 that cooperates with the limiting part 33 on the guide post 34 rotatably disposed in the rotating hole 221, the rotation of the temple 30 can be better guided, making the opening and closing of the temple 30 smoother, and further enhancing the stability of the connection between the temple 30 and the hinge 20.
[0031] To increase the reliability of eyeglass frames during use, such as Figures 1 to 3 As shown, the limiting groove 341 accommodates the limiting part 33 and part of the locking part 32. By using the limiting groove 341 to accommodate the limiting part 33 and part of the locking part 32, the overall integrity of the limiting part 33 and the locking part 32 can be increased by the guide post 34, thereby increasing the firmness of the connection between the temple 30 and the hinge 20 and achieving the purpose of increasing the reliability of the eyeglass frame during use.
[0032] To improve the rotational stability of the temple 30, such as Figure 3 As shown, there are two limiting grooves 341, which are respectively set at the two opposite ends of the guide post 34. The number of limiting parts 33 and notches 222 is the same as the number of limiting grooves 341. By setting two limiting grooves 341 at the opposite ends of the guide post 34 and having the same number of limiting parts 33 and notches 222, the connection between the temple 30 and the guide post 34 can be made more stable, thereby improving the rotational stability of the temple 30.
[0033] To improve the overall stability of the eyeglass frame structure, such as Figures 3 to 4As shown, the adapter 21 is provided with a slot 211, and the frame 10 is provided with a groove 11 that engages with the slot 211. The slot 211 of the adapter 21 engages with the groove 11 of the frame 10. After welding, it helps to increase the stable connection between the frame 10 and the hinge 20, making it less prone to loosening, thereby achieving the purpose of improving the overall stability of the eyeglass frame structure.
[0034] To improve the ease of installation of the limiting part 33, such as Figures 3 to 4 As shown, the rotating part 22 has a cylindrical structure and the notch 222 is a fan-shaped notch opened along the axial direction. The fan-shaped notch 222 opened along the axial direction makes it easier for the limiting part 33 of the temple 30 to be installed into the rotating hole 221, thereby improving the installation convenience of the limiting part 33.
[0035] To improve the aesthetics of hinge 20, such as Figure 4 As shown, the abutment 23 is an annular stop provided on the side of the rotating part 22. By providing the abutment 23 with the annular stop on the side of the rotating part 22, the angle at which the temple 30 unfolds outward can be effectively limited. Moreover, the structure is simple and beautiful, thus improving the aesthetics of the hinge 20.
[0036] To enhance the user experience of the flexible leg body 31, the flexible leg body 31 is made of one of the following materials: elastic plastic, rubber, or metal. The flexible leg body 31, made of one of the following materials, can bend during assembly and return to its original shape and maintain a certain strength after assembly, thereby improving the user experience of the flexible leg body 31.
[0037] During assembly of the easy-to-assemble eyeglass frame 100 provided in this application: First, hold the temple 30 and apply force to the flexible temple body 31 to bend it. Because the flexible temple body 31 is elastic, it can deform under force. Control the limiting part 33, which is located in the movable groove 321 of the locking part 32, to gradually approach the notch 222 of the rotating part 22 of the hinge 20, so that the limiting part 33 smoothly passes through the notch 222 and enters the rotating hole 221 of the rotating part 22. At this time, stop applying the force to bend the flexible temple body 31. By restoring its original shape through its own elasticity, it is aligned with the snap-fit part 32. At the same time, due to the obstruction of the frame 10, the limiting part 33 cannot rotate to the position corresponding to the notch 222, thus completing the initial assembly of the temple 30 and the hinge 20. Next, the slot 211 of the hinge 20 adapter part 21 is aligned with the groove 11 on the frame 10, and the hinge 20 and the frame 10 are connected by welding, so that the slot 211 and the groove 11 are tightly engaged, completing the connection between the frame 10 and the hinge 20. At this point, the entire eyeglass frame assembly is complete.
[0038] When the easy-to-assemble eyeglass frame 100 provided in this application is in use: the temples 30 are unfolded outwards. During the unfolding process, the locking part 32 rotates along the outer periphery of the rotating part 22, and the limiting part 33 rotates synchronously within the rotating hole 221. When the temples 30 are unfolded to a suitable angle, the locking part 32 and the supporting part 23 abut against each other, restricting the temples 30 from continuing to unfold outwards. At this time, the eyeglass frame is in the wearing state, and the user can wear the glasses on the head. The position and angle of the temples 30 are stably maintained, providing the user with a comfortable wearing experience.
[0039] When the easy-to-assemble eyeglass frame 100 provided in this application is stored, the temples 30 are folded inward. During the folding process, the flexible temple body 31 gradually approaches the frame 10 until it contacts the frame 10. At this time, the frame 10 blocks the flexible temple body 31. Since the position of the limiting part 33 in the rotation hole 221 is restricted by the frame 10 and the flexible temple body 31, it cannot rotate to the position corresponding to the notch 222, thereby preventing the temples 30 from disengaging from the hinge 20. The space occupied by the folded eyeglass frame is greatly reduced, making it easy to store and carry.
[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
