Abstract
Description
Technical Field
[0001] This utility model relates to the field of screwless eyeglass assembly, specifically to a screwless and weldless temple steel hinge structure. Background Technology
[0002] Generally, eyeglasses have temples attached to both sides of the frame. The temples are connected by a pivot at the front end, which aligns with the frame's pivot, and then screwed together. This allows the temples to be opened or folded. Assembling eyeglasses with screws requires tools like screwdrivers to secure them, increasing labor and time costs, and also raising manufacturing costs. Furthermore, the repeated opening and closing of the temples by the user can easily cause screws to loosen or fall out. However, loose screws require special tools to tighten, and if lost, repairs and replacements must be made at an optician. These shortcomings often inconvenience eyeglass wearers.
[0003] As a result, many eyeglass structures that do not require screw assembly have been developed in the market, such as the utility model patent with application number TW097212952, entitled "Eyeglass Hinge Device". However, although the aforementioned patents can improve the problems caused by screw locking, they are not convenient to assemble and the temples are not effectively limited when unfolding or closing, which makes them slightly inadequate in use.
[0004] Furthermore, as in the utility model patent application number TW112204954 entitled "Screwless and Solderless Eyeglass Structure," a pair of eyeglasses with operational flexibility in unfolding and closing is disclosed. It includes: a frame and a temple disposed on both sides of the frame, wherein the temple and the frame are connected by a mortise and tenon joint structure; the mortise and tenon joint structure is assembled from a frame structure, a hook structure, a spring structure and a tie head structure.
[0005] While the aforementioned technologies can assist in opening and closing through appropriate elasticity during operation, their overall structure is complex, with many components and difficult assembly. Furthermore, the existing technology is time-consuming, labor-intensive, and costly to process by extruding irregular strips, cutting hinge teeth, and then welding. Utility Model Content
[0006] The purpose of this utility model is to provide a screwless and weldless mirror temple steel plate hinge structure, especially a screwless and weldless mirror temple steel plate hinge structure that is simple in structure, easy to assemble, and has high stability. It aims to improve the problems of complex overall structure, many components, and difficult assembly, as well as the defects of existing technology that use irregular extrusion strip processing, then cutting hinge teeth, and then welding, which is time-consuming, labor-intensive, and costly.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A screwless and weldless temple steel plate hinge structure is provided, wherein at least one steel plate hinge structure is provided between the assembly part on the outer side of the frame and the front end of the temple, the steel plate hinge structure comprising,
[0009] The hinge unit has a first hook, a second hook, and a third hook on one side from front to back. The front end has a positioning hole corresponding to the third hook for locking and fixing. The front end has a through hole in front of the positioning hole, which allows the first hook and the second hook to pass through. The end edge of the assembly part has a notch for inserting the second hook. The notch provides space for the hinge unit to move the temple open and close. The assembly part has a locking hole and a locking hole in sequence from the notch towards the frame. The locking hole allows the second hook to be inserted and positioned when the hinge unit moves the temple close. The locking hole allows the first hook to be inserted and positioned when the hinge unit moves the temple open.
[0010] Furthermore, there is a wall thickness between the notch and the locking hole, and a hook-ring space is formed on the inner side of the second hook. The second hook and the hook-ring space are positioned by hooking and engaging the wall thickness.
[0011] Furthermore, the frame and temples are manufactured using laser cutting technology.
[0012] Furthermore, the hinge unit is made from the scrap material of the laser-cut frame, which is then processed by laser cutting.
[0013] Furthermore, the temple of the mirror has an end portion at the other end opposite to the front end, and a Bluetooth communication module is installed on the end portion.
[0014] Furthermore, the frame, temples, and hinge unit are made of stainless steel.
[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0016] 1. The screwless and weldless mirror temple steel plate hinge structure replaces the traditional screw-locked hinge. Through the elastic opening and closing of the steel plate hinge structure, it has the good function and advantages of not needing screws and not being easy to loosen.
[0017] 2. The screwless and weldless mirror temple steel plate hinge structure uses steel plate scraps cut directly from the frame surface to form the hinge. Compared with existing technologies, it not only has the advantages of simple components and convenient assembly, but also reduces costs and is environmentally friendly.
[0018] 3. Made of 301 stainless steel, it has excellent work hardening properties and strength, which can not only effectively extend the service life, but also achieve good stability due to the elastic force formed by the rigid reaction force of the mirror temple steel plate and the two-stage spring functional structure adopted in the embodiment, which is not easy to loosen or loosen.

[0034] Example
[0035] This embodiment provides a screwless and weldless mirror temple steel plate hinge structure. Please refer to... Figure 1 , 2 and Figure 5 As shown, at least one steel hinge structure 3 is provided between the outer assembly portion 11 of the frame 1 and the front end portion 21 of the temple 2. The steel hinge structure 3 includes:
[0036] A hinge unit 31 has a first hook 311, a second hook 312, and a third hook 313 on one side from front to back. The front end 21 has a positioning hole 32 corresponding to the third hook 313 for locking and fixing. The front end 21 has a through hole 33 in front of the positioning hole 32, which allows the first hook 311 and the second hook 312 to pass through. The end edge of the assembly part 11 has a notch 34 for the second hook 312 to be inserted. The notch 34 provides the hinge unit 31 to move the temple 2 to open and close. The assembly part 11 has a locking hole 35 and a locking hole 36 in sequence in the direction of the frame 1 from the notch 34. The locking hole 35 allows the second hook 312 to be inserted and positioned when the hinge unit 31 moves the temple 2 to close, while the locking hole 36 allows the first hook 311 to be inserted and positioned when the hinge unit 31 moves the temple 2 to open.
[0037] When using the installation, please refer to Figure 1-5 As shown, the number of steel plate hinge structures 3 can be determined according to the design of the frame 1 assembly 11 and the front end 21 of the temple 2. In the figure, it is represented by two sets of steel plate hinge structures. The two sets can achieve effective balanced operation and there will be no angle problem. The following is a detailed description.
[0038] In this embodiment, the frame 1 and temple 2 are made using laser cutting technology. The hinge unit 31 is made from the scrap material of the frame 1 after laser cutting. During assembly, the third hook 313 of the hinge unit 31 is locked and fixed to the positioning hole 32 of the temple 2, while the first hook 311 and the second hook 312 pass through the through hole 33. Furthermore, there is a wall thickness 111 between the notch 34 and the locking hole 35, and a hook-ring space 314 is formed on the inner side of the second hook 312. When the second hook 312 passes through the notch 34, the hook-ring space 314 hooks the wall thickness 111 and is positioned. At the same time, the first hook 311 is embedded in the locking hole 36 of the assembly part 11 of the frame 1. In this way, the temple 2 is installed on the frame 1 and is in an unfolded state.
[0039] Please refer to Figure 7 As shown, the other end of the temple 2 opposite to the front end 21 is provided with an end portion 22, and a Bluetooth communication module 4 is installed on the end portion 22.
[0040] Please refer to Figure 5 and Figure 6 As shown, when the user wants to close the glasses, they push the temple 2, causing it to move inwards towards the inner side of the frame 1. The second hook 312 of the hinge unit 31 rotates around the hook space 314 and the interlocking wall thickness 111, allowing the second hook 312 to engage with the locking hole 35, while the first hook 311 disengages from the locking hole 36. At this time, the torque generated by the second hook 312 rotating and engaging with the locking hole 35 acts on the front end 21 of the temple 2, creating a rebound force that establishes a spring-loaded positioning between the frame 1 and the temple 2. Therefore, when the temple 2 is unfolded again, the spring force can be easily released by gently pushing the temple 2 outwards through the rebound force.
[0041] In this embodiment, the frame 1, temple 2, and hinge unit 31 are made of stainless steel, specifically 301 stainless steel. 301 stainless steel is a classic austenitic stainless steel, widely used due to its excellent work hardening properties and strength. Utilizing the rigidity of 301 stainless steel sheets, a snap-fit structure is designed to replace the traditional hinge welding method, and the rigid reaction force of the temple steel sheet forms an elastic force to replace the traditional spring hinge, as well as the traditional hinge that requires screws. This is the weld-free temple steel sheet hinge structure disclosed in this embodiment, which has a hinge technology that is not easy to loosen, effectively replacing the traditional hinge and providing the temple 2 with opening and closing elasticity and a screwless, non-loosening effect.
[0042] The foregoing embodiments or figures are not intended to limit the structural form of this invention. Any appropriate changes or modifications by those skilled in the art should be considered as not departing from the patent scope of this invention.
[0043] In summary, compared with existing technologies, this embodiment has the following advantages:
[0044] 1. The screwless and weldless mirror temple steel plate hinge structure replaces the traditional screw-locked hinge. Through the elastic opening and closing of the steel plate hinge structure, it has the good function and advantages of not needing screws and not being easy to loosen.
[0045] 2. The screwless and weldless mirror temple steel sheet hinge structure uses steel sheet scraps from the frame to directly cut and form the hinge. Compared with existing technologies, it not only has simple components and convenient assembly, but also reduces costs and is environmentally friendly.
[0046] 3. Made of 301 stainless steel, it has excellent work hardening properties and strength, which not only effectively extends the service life, but also creates elastic force due to the rigid reaction force of the mirror temple steel plate, and the two-stage spring functional structure adopted in the embodiment achieves good stability that is not easy to loosen or loosen.
[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
