Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a structure for adjusting the distance between temples using an elastic telescopic rod. Background Technology

[0002] Throughout the development of eyeglasses, temple design has always been a key factor affecting the wearing experience. Traditional eyeglasses have a fixed temple spacing, making it difficult to adapt to the different head shapes of different users. Users with wider heads will find the temples too tight, causing a feeling of pressure, discomfort in the ears and head, and even affecting blood circulation. Users with narrower heads will face the problem of their glasses slipping off easily, requiring frequent adjustments when walking or exercising, which is extremely inconvenient.

[0003] Moreover, conventional temples are mostly rigid structures, which cause significant friction to the skin of the ears when wearing and removing them. Prolonged wear can easily lead to ear fatigue and pain. When the glasses are hit or squeezed, the temples are also prone to breakage or deformation, resulting in damage to the glasses and increasing the replacement cost for users. In addition, the traditional temple ear loops have a limited range of styles and cannot meet the diverse usage scenarios and fashion matching needs of users. In view of these pain points, it is particularly necessary to develop a pair of glasses with adjustable temple spacing, elastic cushioning, and replaceable ear loops. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a structure for adjusting the distance between the temples with an elastic telescopic rod, which can solve the existing problems of wearing comfort, temple structure protection, and personalized needs.

[0006] To solve the above technical problems, this utility model provides an elastic telescopic rod structure for adjusting the temple spacing, adopting the following technical solution: it includes an outer temple, an elastic rod is slidably connected inside the outer temple, a groove is provided inside the elastic rod, a metal strip is slidably connected inside the groove, a fixing plate is fixedly connected to the front end of the outer temple, an elastic strip is fixedly connected to the front end of the fixing plate, a first connecting ring is slidably connected to the outer surface of the elastic strip through a through hole, and a replaceable hanging ear structure is provided at the rear end of the elastic rod; The replaceable lug structure includes a first connector, a second connector, a lug section, a threaded head, a second connecting ring, a first magnet, and a second magnet.

[0007] Optionally, a limiting member is fixedly connected to the front end of the elastic strip, and the rear end of the limiting member contacts the first connecting ring.

[0008] The above technical solution limits the sliding range of the first connecting ring on the elastic strip by setting a limiting component to contact the first connecting ring, thus ensuring the stability of the structure and the accuracy of adjustment.

[0009] Optionally, a connecting post is fixedly connected to the front end of the first connecting ring, and an elastic connector is fixedly connected to the front end of the connecting post.

[0010] The above technical solution introduces elastic connectors, which allow the temples to better buffer external forces during adjustment, improving wearing comfort and enhancing the elasticity of the structure.

[0011] Optionally, the number of elastic strips is six and they are evenly distributed at the front end of the fixing plate, and the number of through holes is six and they correspond one-to-one with the positions of the elastic strips.

[0012] The above technical solution specifies the number and distribution of elastic strips and through holes, ensuring that the elastic effect of the elastic strips is evenly distributed, making the force on the temples more balanced and improving the stability of adjustment.

[0013] Optionally, the front end of the metal strip is fixedly connected to the fixing plate, and the front end of the elastic rod is provided with a limiting ring, the outer side of which is slidably connected to the outer temple of the eyeglass.

[0014] The above technical solution involves fixing the metal strip to the fixing plate and combining it with the sliding connection between the limiting ring and the outer temple to ensure the stability and directionality of the elastic rod when it slides inside the outer temple, thus preventing the elastic rod from sliding out excessively.

[0015] Optionally, the rear end of the elastic rod is fixedly connected to the first connecting member, the inner wall of the first connecting member is threadedly connected to the threaded head, the interior of the threaded head is fixedly connected to the second connecting ring, the rear end of the second connecting ring is fixedly connected to the second connecting member, and the rear end of the second connecting member is fixedly connected to the lug section.

[0016] The above technical solution allows for the replacement of the ear-mounted structure, enabling the ear-mounted section to be detachable via a threaded connection, thus facilitating the replacement of different styles of ear-mounted sections by the user.

[0017] Optionally, the rear end of the first connector is fixedly connected to the first magnet, the rear end of the second connector is fixedly connected to the second magnet, and the first magnet and the second magnet are magnetically connected.

[0018] The above technical solution enhances the stability of the replaceable ear structure by utilizing the magnetic connection between the first and second magnets, preventing the ear section from accidentally falling off during use.

[0019] Optionally, the ear loop section has a hollow groove inside, and the number of hollow grooves is multiple and evenly distributed inside the ear loop section.

[0020] The above technical solution involves setting multiple evenly distributed hollow grooves inside the ear loop section, which reduces the weight of the ear loop section, improves wearing comfort, and may also increase the flexibility of the ear loop section.

[0021] In summary, this utility model has at least one of the following beneficial effects: 1. Comfortable to wear: The elastic strips and elastic connectors deform elastically when the temples are subjected to external force, which can effectively buffer the impact of various external forces on the ears and head. During the process of putting on and taking off glasses, the friction and pressure on the skin of the ears caused by the rigid structure of the temples are reduced, providing a more comfortable wearing experience. For users who wear glasses for a long time, this cushioning design can significantly reduce ear fatigue and make the wearing process more relaxed and pleasant.

[0022] 2. Personalized customization: The replaceable ear hook design allows users to easily change to different styles or sizes of ear hooks according to personal preferences, different usage scenarios, and fashion matching needs. For example, when exercising, users can switch to ear hooks that fit the ears better and have anti-slip function, while when working, they can choose a simple and beautiful style, which meets the diverse needs of users and brings them more fun and personalized experience.

[0027] Reference Figure 1-4 This utility model embodiment of the elastic telescopic rod adjusting temple spacing structure includes an outer temple 1, with an elastic rod 2 slidably connected inside the outer temple 1. The elastic rod 2 can adjust the rear end over a wider range. A groove 7 is provided inside the elastic rod 2, and a metal strip 4 is slidably connected inside the groove 7. A fixing plate 18 is fixedly connected to the front end of the outer temple 1, and an elastic strip 16 is fixedly connected to the front end of the fixing plate 18. A first connecting ring 5 is slidably connected to the outer surface of the elastic strip 16 through a through hole 19. The elastic strip 16 is elastic, allowing the first connecting ring 5 at the front end to adjust over a wider range. The rear end of the 2 is provided with a replaceable ear structure. The front end of the elastic strip 16 is fixedly connected to the limiting member 17. The rear end of the limiting member 17 contacts the first connecting ring 5. The front end of the first connecting ring 5 is fixedly connected to the connecting post 20. The front end of the connecting post 20 is fixedly connected to the elastic connecting member 6. There are six elastic strips 16 and they are evenly distributed at the front end of the fixing plate 18. There are six through holes 19 and they correspond one-to-one with the positions of the elastic strips 16. The front end of the metal strip 4 is fixedly connected to the fixing plate 18. The front end of the elastic rod 2 is provided with a limiting ring 3. The outer side of the limiting ring 3 is slidably connected to the outer temple 1.

[0028] The replaceable lug structure includes a first connector 8, a second connector 9, a lug section 10, a threaded head 12, a second connecting ring 13, a first magnet 14, and a second magnet 15. The rear end of the elastic rod 2 is fixedly connected to the first connector 8. The inner wall of the first connector 8 is threadedly connected to the threaded head 12. The inside of the threaded head 12 is fixedly connected to the second connecting ring 13. The rear end of the second connecting ring 13 is fixedly connected to the second connector 9. The rear end of the second connector 9 is fixedly connected to the lug section 10. The rear end of the first connector 8 is fixedly connected to the first magnet 14. The rear end of the second connector 9 is fixedly connected to the second magnet 15. The first magnet 14 and the second magnet 15 are magnetically connected. The lug section 10 has multiple hollow grooves 11 that are evenly distributed inside the lug section 10.

[0029] Working principle: When adjusting the temple spacing, the user manually operates the elastic rod 2, allowing it to slide within the outer temple 1. The sliding groove 7 inside the elastic rod 2 plays a crucial role, as it closely cooperates with the metal strip 4. The front end of the metal strip 4 is firmly fixed to the fixing plate 18, which in turn is fixed to the front end of the outer temple 1. This structural design ensures that when the elastic rod 2 slides, the metal strip 4 acts like a track, restricting the elastic rod 2 to slide only in a specific direction. This ensures that the elastic rod 2 can extend and retract stably and smoothly within the outer temple 1. As the elastic rod 2 extends and retracts, the overall length of the temple changes, thereby achieving precise adjustment of the temple spacing.

[0030] The limiting ring 3 at the front end of the elastic rod 2 is designed with an outer diameter that matches the inner diameter of the outer temple 1, allowing it to slide inside the elastic rod 2 and the outer temple 1. The main function of the limiting ring 3 is to prevent the elastic rod 2 from sliding excessively out of the outer temple 1, thus avoiding damage to the temple structure or affecting normal use due to excessive stretching. When the elastic rod 2 slides outward to a certain extent, the limiting ring 3 will contact the inner wall of the outer temple 1, preventing the elastic rod 2 from moving further outward, thereby ensuring the safety and stability of the temple adjustment structure. Six elastic strips 16 are evenly distributed at the front end of the fixing plate 18. This distribution allows the elastic force to act evenly on the relevant components. The first connecting ring 5 is slidably connected to the elastic strips 16 through six through holes 19 that correspond to its position. The connecting post 20 at the front end of the first connecting ring 5 is firmly connected to the elastic connecting piece 6. When the temples are subjected to external forces during wear, such as torsional or tensile forces applied when putting on or taking off the glasses, or impact forces generated by collisions during daily use, the elastic strip 16 and elastic connector 6 play a crucial role. The elastic strip 16 itself has excellent elastic properties and undergoes elastic deformation when subjected to external forces, absorbing some of the energy. Simultaneously, the elastic connector 6 further buffers the external forces, dispersing and offsetting their impact on the overall temple structure through its own elastic deformation. This not only adapts to various movements and postures of different users, improving wearing comfort, but also effectively protects the temple structure and extends the lifespan of the glasses. The elastic rod 2's rear end... The connector 8 and the threaded head 12 are connected by a thread. This connection method is simple to operate and has a firm connection. When the user needs to replace the lug section 10, he / she can easily connect and disconnect the lug section 10 from the elastic rod 2 by simply rotating the threaded head 12. Specifically, the threaded head 12 has a second connecting ring 13 fixed inside. The rear end of the second connecting ring 13 is connected to the second connector 9 and the lug section 10 in sequence. When the threaded head 12 is rotated, the second connector 9 and the lug section 10 will move together due to the transmission action of the thread, thereby achieving the purpose of installing or removing the lug section 10. This allows users to replace the lug section 10 with different styles or sizes according to their personal preferences or actual needs.

[0031] To further enhance the stability of the lug segment 10 connection and prevent it from accidentally falling off during daily use, the rear ends of the first connector 8 and the second connector 9 are respectively fixed with a first magnet 14 and a second magnet 15. After the lug segment 10 is installed in place, the first magnet 14 and the second magnet 15 will approach each other and generate magnetic attraction, so that the first connector 8 and the second connector 9 are tightly connected together. This magnetic connection method can provide additional fastening force for the connection of the lug segment 10 on the basis of the threaded connection, ensuring that the lug segment 10 can be stably connected to the elastic rod 2 in various usage environments.

[0032] The ear loop section 10 has multiple evenly distributed hollow grooves 11 inside. The existence of these hollow grooves 11 has multiple functions. On the one hand, they effectively reduce the overall weight of the ear loop section 10, making the glasses lighter and more comfortable to wear, and reducing the burden on the ears caused by wearing them for a long time. On the other hand, the structural design of the hollow grooves 11 increases the elasticity and flexibility of the ear loop section 10. When the ear loop section 10 comes into contact with the user's ear, it can better fit the ear contour, adapt to the differences in ear shape and size of different users, improve the comfort and stability of wearing, and at the same time, it can also cushion the pressure from the ear to a certain extent and protect the ear skin.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
