Description

Technical Field

[0001] This invention relates to the field of eyeglasses technology, and more particularly to a type of eyeglasses that prevents loosening. Background Technology

[0002] The hinge is a crucial component connecting the frame and temples of eyeglasses. The temples are hinged to the frame's posts via the hinge, allowing the temples to open and close relative to the frame. Existing eyeglasses, especially AR or AI glasses, cannot use elastic materials for the temples because the temples contain circuit boards and other components. Furthermore, as entertainment-oriented glasses, AR and AI glasses differ from everyday eyeglasses in their wearing method. They cannot be personalized in a physical store based on individual head circumference. Since each user's head shape and face width are different, the temples are prone to loosening and falling off, or excessive clamping force causing pain, negatively impacting the user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a non-loosening eyeglasses that adjusts the clamping force of the temples according to the user's different head circumference, avoiding the temples being too loose or too tight, thereby improving the versatility and user experience of the non-loosening eyeglasses.

[0004] To achieve this objective, the technical solution adopted by the present invention is as follows: Anti-loosening eyeglasses include a frame, temples, and an anti-loosening component. The temples have a locking ring at their fixed ends, and one end of the locking ring has at least two first anti-loosening teeth spaced circumferentially. The anti-loosening component includes: A shaft passes through the locking ring and is installed on the head of the mirror frame; the fixed end of the temple is hinged to the head of the frame via the shaft; a limit plate is provided on the shaft for adjustable axial position. A gear disc, which is circumferentially limited and axially movable, is sleeved on the shaft. The gear disc is located above the locking ring, and a second anti-loosening tooth is provided circumferentially at one end of the gear disc facing the locking ring. An elastic element is installed between the limiting plate and the toothed disc; when the temple is in a folded position stacked on the frame or unfolded 90° relative to the frame, the elastic element drives the second anti-loosening tooth to engage between two adjacent first anti-loosening teeth; when the temple is unfolded to other angles relative to the frame, the elastic element drives the tooth surface of the second anti-loosening tooth to abut against the tooth surface of one of the first anti-loosening teeth, so that the temple has a tendency to flip inward to the folded position.

[0005] As an optional solution for anti-loosening eyeglasses, the shaft includes: A main shaft, one end of which passes through the locking ring and is installed on the pile head, and a gear plate that is circumferentially limited and axially movable is sleeved on the main shaft; An external threaded sleeve, one end of which is movably fitted onto the other end of the main shaft, is threadedly connected to the pile head, and a limiting plate is installed on the external threaded sleeve.

[0006] As an optional solution for locking eyeglasses, an adjustment hole is provided at the end of the external threaded sleeve away from the main shaft, so that the external threaded sleeve can be screwed through the adjustment hole.

[0007] As an optional solution for anti-loosening eyeglasses, the outer periphery of the main shaft is provided with a first tangent plane along the axial direction, and the inner ring of the gear disc is provided with a second tangent plane along the axial direction, with the first tangent plane and the second tangent plane fitting together.

[0008] As an optional solution for anti-loosening glasses, the elastic element is a spring, which is sleeved on the main shaft, with one end of the spring abutting against the limiting plate and the other end of the spring abutting against the end of the toothed disc away from the second anti-loosening tooth.

[0009] As an optional solution for anti-loosening eyeglasses, the limiting plate is threadedly connected to the external threaded sleeve; or, the limiting plate is welded to the outer circumferential surface of the external threaded sleeve.

[0010] As an optional solution for anti-loosening glasses, the temple includes a temple body and a first mounting component. The first mounting component is detachably mounted on one end of the temple body. The first mounting component is provided with the locking ring and is hinged to the post head through the shaft.

[0011] As an optional solution for locking glasses, the first mounting component has a first wall panel and a second wall panel arranged opposite to each other, the first wall panel and the second wall panel forming a receiving groove, and the locking ring is integrally protruding from the inner bottom wall of the receiving groove; when the temple is in the folded position, the first wall panel is exposed to the post head to cover the receiving groove; when the temple is unfolded 90° relative to the frame, the second wall panel is exposed to the post head to cover the receiving groove.

[0012] As an optional solution for anti-loosening glasses, the pile head includes a pile head body and a second mounting component. The pile head body is detachably mounted with the second mounting component, and both ends of the shaft are mounted on the second mounting component.

[0013] As an alternative to anti-loosening glasses, the second mounting member has cantilevers spaced axially along the shaft, and a portion of the first mounting member extends between the two cantilevers and is hinged to the two cantilevers via the shaft.

[0014] The beneficial effects of this invention are as follows: The anti-loosening glasses proposed in this invention, when the temples are in a folded position stacked on the frame or unfolded 90° relative to the frame, have an elastic element driving a second anti-loosening tooth to engage between two adjacent first anti-loosening teeth. When the temples are unfolded to other angles relative to the frame, the elastic element drives the tooth surface of the second anti-loosening tooth to abut against the tooth surface of a corresponding first anti-loosening tooth, thus preventing the temples from unfolding further. Specifically, the toothed disc, under the elastic restoring force of the elastic element, presses against the locking ring, pushing the temples inward through the locking ring, thereby clamping the two temples tightly against the user's head and preventing the glasses from falling off due to insufficient clamping force. Simultaneously, the elastic element is installed between the limiting plate and the toothed disc, and the axial position of the limiting plate along the shaft is adjustable. That is, by changing the axial position of the limiting plate on the shaft, the pressure on the elastic element is adjusted, i.e., the elastic restoring force applied by the elastic element to the toothed disc is adjusted, thereby adjusting the clamping force of the temples and preventing the temples from being too loose or too tight. Anti-loosening glasses can adjust the clamping force of the temples according to different head circumferences of users, ensuring that the temples are clamped tightly without hurting the user, thus improving the versatility and user experience of anti-loosening glasses.

Detailed Implementation

[0017] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Existing eyeglasses, especially AR or AI glasses, cannot use elastic materials for the temples because the temples contain circuit boards and other components. Furthermore, as entertainment-oriented glasses, AR and AI glasses differ from regular eyeglasses in their wearing method. They cannot be personalized in a physical store based on individual head circumference. Since each user's head shape and face width are different, the temples are prone to loosening and falling off, or the clamping force is too strong and causes pain, affecting the user experience.

[0023] To solve the above problems, such as Figures 1-4 As shown, this embodiment proposes an anti-loosening glasses, which can be AR glasses, AI glasses, myopia glasses, or sunglasses, etc., without specific limitations. The anti-loosening glasses include a frame 10, temples 20, and an anti-loosening component. The fixed end of the temple 20 is provided with a locking ring 53, and one end of the locking ring 53 is provided with at least two first anti-loosening teeth 531 spaced apart circumferentially. The anti-loosening component includes a shaft 1, a gear disc 2, and an elastic element 3. The shaft 1 passes through the locking ring 53 and is installed on the post 101 of the frame 10. The fixed end of the temple 20 is hinged to the post 101 through the shaft 1. The shaft 1 is provided with a limiting plate 13 that is axially adjustable. The gear disc 2 is circumferentially limited and axially movable and sleeved on the shaft 1. The gear disc 2 is located above the locking ring 53, and the end of the gear disc 2 facing the locking ring 53 is provided with a second anti-loosening tooth 21 circumferentially. The elastic element 3 is installed between the limiting plate 13 and the gear disc 2. When the temple 20 is in the folded position stacked on the frame 10 or unfolded 90° relative to the frame 10, the elastic member 3 drives the second anti-loosening tooth 21 to be locked between two adjacent first anti-loosening teeth 531; when the temple 20 is unfolded to other angles relative to the frame 10, the elastic member 3 drives the tooth surface of the second anti-loosening tooth 21 to abut against the tooth surface of a corresponding first anti-loosening tooth 531, so that the temple 20 has a tendency to flip inward (towards the frame 10) to the folded position.

[0024] like Figure 3 As shown, when the temple 20 is in the folded position stacked on the frame 10 or unfolded 90° relative to the frame 10, the elastic element 3 drives the second anti-loosening tooth 21 to lock between two adjacent first anti-loosening teeth 531. Figure 4As shown, when the temple 20 is extended to other angles relative to the frame 10, the elastic element 3 drives the tooth surface of the second anti-loosening tooth 21 to abut against the tooth surface of the corresponding first anti-loosening tooth 531 to prevent the temple 20 from extending further. That is, under the action of the elastic restoring force of the elastic element 3, the toothed disc 2 squeezes the locking ring 53, so that the locking ring 53 pushes the temple 20 to flip inward, thereby clamping the two temples 20 tightly to the user's head and preventing the glasses from falling off due to insufficient clamping force of the temples 20. At the same time, the elastic element 3 is installed between the limiting plate 13 and the toothed disc 2, and the axial position of the limiting plate 13 along the shaft 1 is adjustable. That is, by changing the axial position of the limiting plate 13 on the shaft 1, the pressure of the elastic element 3 can be adjusted, that is, the elastic restoring force applied by the elastic element 3 to the toothed disc 2 can be adjusted, thereby adjusting the clamping force of the temple 20 and preventing the temple 20 from being too loose or too tight. The anti-loosening glasses can adjust the clamping force of the temples 20 according to the user's different head circumference, which can ensure that the temples 20 are clamped tightly without hurting the user, thus improving the versatility and user experience of the anti-loosening glasses.

[0025] In this embodiment, the folded position of the temple 20 refers to the position where the temple 20 rotates inward around the post head 101 until it is close to the outer edge of the frame 10, at which point the temple 20 is in a retracted posture. The axial direction in this embodiment is the up-down direction as shown in the figure. The upper end of the locking ring 53 is provided with four first anti-loosening teeth 531 at equal intervals along the circumference, forming a tooth groove between two adjacent first anti-loosening teeth 531. The first anti-loosening teeth 531 and the second anti-loosening teeth 21 have the same structure, both being V-shaped tooth structures with flat tooth tips, so that when the second anti-loosening tooth 21 is engaged in the tooth groove, the two tooth surfaces of the second anti-loosening tooth 21 are completely in contact with the tooth surfaces of the two adjacent first anti-loosening teeth 531, thereby achieving stable engagement and locking between the toothed disc 2 and the locking ring 53. Furthermore, two second anti-loosening teeth 21 are evenly spaced along the circumference at the lower end of the gear disc 2, so that the elastic element 3 applies a pushing force to the locking ring 53 through the two symmetrically arranged second anti-loosening teeth 21, achieving uniform force distribution on the locking ring 53 and improving the stability and reliability of the inward flipping of the temple 20. In other embodiments, the number of the first anti-loosening teeth 531 in the locking ring 53 and the number of the second anti-loosening teeth 21 in the gear disc 2 can be flexibly adjusted according to requirements, and no specific limitation is made here.

[0026] like Figure 1 and Figure 2 As shown, the temple 20 includes a temple body 4 and a first mounting component 5. The first mounting component 5 is detachably mounted on one end of the temple body 4. The first mounting component 5 is provided with a locking ring 53 and is hinged to the post head 101 via a shaft 1. The first mounting component 5 is detachably assembled with the temple body 4 to reduce the processing difficulty and production cost of the temple 20. At the same time, it also allows for quick replacement of the first mounting component 5 after the locking ring 53 wears or is damaged, facilitating the later maintenance of the temple 20.

[0027] Specifically, the first mounting component 5 is installed on the temple body 4 by screwing on screws, which not only makes the assembly operation of the first mounting component 5 and the temple body 4 simple and quick, but also improves the assembly strength and stability of the first mounting component 5.

[0028] like Figure 2 and Figure 5 As shown, the first mounting component 5 has a first wall plate 51 and a second wall plate 52 arranged opposite to each other. The first wall plate 51 and the second wall plate 52 form a receiving groove 50, and a locking ring 53 is integrally protruding from the inner bottom wall of the receiving groove 50. When the temple 20 is in the folded position, the first wall plate 51 is exposed to the post head 101 to cover the receiving groove 50; when the temple 20 is unfolded 90° relative to the frame 10, the second wall plate 52 is exposed to the post head 101 to cover the receiving groove 50. Since the anti-loosening component and the locking ring 53 are both located in the receiving groove 50, the first wall plate 51 and the second wall plate 52 prevent the anti-loosening component and the locking ring 53 from being exposed in the folded position and when the temple 20 is unfolded to 90°, thus ensuring the neat and beautiful appearance of the anti-loosening glasses. Meanwhile, the first wall panel 51 and the second wall panel 52 can also provide physical isolation and protection for the anti-loosening components, effectively preventing foreign objects and liquids from entering the receiving tank 50, and can also effectively prevent users from accidentally contacting the anti-loosening components and being injured, thus improving the safety of the anti-loosening glasses during storage or use.

[0029] like Figure 1 and Figure 2 As shown, the pile head 101 includes a pile head body 6 and a second mounting component 7. The pile head body 6 is detachably mounted with the second mounting component 7, and both ends of the shaft 1 are mounted on the second mounting component 7. The second mounting component 7 is detachably assembled with the pile head body 6 to reduce the processing difficulty and production cost of the mirror frame 10. At the same time, the second mounting component 7 can be quickly replaced, facilitating the later maintenance of the mirror frame 10.

[0030] Specifically, the second mounting component 7 is installed on the pile head body 6 by screwing on screws, which not only makes the assembly operation of the second mounting component 7 and the pile head body 6 simple and quick, but also improves the assembly strength and stability of the second mounting component 7.

[0031] like Figures 2-4 As shown, the second mounting member 7 has cantilever 71 spaced axially along the shaft 1. A portion of the first mounting member 5 extends between the two cantilever 71 and is hinged to the two cantilever 71 via the shaft 1. The hinged connection between the second mounting member 7 and the first mounting member 5 via the two cantilever 71 simplifies the structure of the second mounting member 7. Furthermore, the portion of the first mounting member 5 with the receiving groove 50 extending between the two cantilever 71 achieves a compact assembly of the first mounting member 5 and the second mounting member 7, reducing the space occupied by the first mounting member 5 and the second mounting member 7, which is beneficial for miniaturizing the anti-loosening glasses.

[0032] like Figure 2 and Figure 6 As shown, the shaft 1 includes a main shaft 11 and an external threaded sleeve 12. One end of the main shaft 11 passes through a locking ring 53 and is installed on the pile head 101. The gear plate 2 is circumferentially limited and axially movable, sleeved on the main shaft 11. One end of the external threaded sleeve 12 is movably sleeved on the other end of the main shaft 11. The external threaded sleeve 12 is threadedly connected to the pile head 101. A limiting plate 13 is installed on the external threaded sleeve 12. By installing the limiting plate 13 on the external threaded sleeve 12, the limiting plate 13 and the external threaded sleeve 12 move up and down synchronously along the axial direction of the main shaft 11, thereby adjusting the distance between the limiting plate 13 and the gear plate 2, that is, the degree of compression of the elastic element 3, which is the clamping force fed back to the temple 20 by the elastic element 3.

[0033] Specifically, one end of the main shaft 11 passes through the locking ring 53 and the lower cantilever 71 of the second mounting piece 7, and is locked to the lower cantilever 71 by a locking nut. The external threaded sleeve 12 is threaded into the upper cantilever 71, achieving stable assembly of the shaft 1 between the two cantilever 71s. By screwing on the external threaded sleeve 12, it can be moved up and down along the axial direction of the main shaft 11, thereby adjusting the position of the limiting plate 13, making the adjustment operation simple and easy, and improving adjustment efficiency. It should be noted that during the adjustment of the position of the limiting plate 13, the external threaded sleeve 12 remains fitted onto the main shaft 11; that is, the two will not separate.

[0034] Furthermore, an adjustment hole 121 is provided at the end of the external threaded sleeve 12 away from the main shaft 11, so that the external threaded sleeve 12 can be screwed through the adjustment hole 121. By using a specific adjustment tool to extend into the adjustment hole 121, the screwing operation of the external threaded sleeve 12 can be realized, which reduces the adjustment difficulty and further improves the adjustment efficiency.

[0035] Specifically, the pile head body 6 has an operating hole, which is directly opposite and connected to the adjustment hole 121. The adjustment hole 121 is an internal hexagonal hole, and the adjustment tool is an internal hexagonal wrench, which allows for quick tightening of the external threaded sleeve 12. In other embodiments, the adjustment tool can also be other tools capable of tightening the external threaded sleeve 12, which will not be listed here.

[0036] In this embodiment, the limiting plate 13 can be a nut that mates with the external threaded sleeve 12, allowing the limiting plate 13 and the external threaded sleeve 12 to be threadedly connected. This design makes the limiting plate 13 inexpensive and readily available, eliminating the need for additional machining and reducing the cost of the anti-loosening glasses. Furthermore, the limiting plate 13 and the external threaded sleeve 12 achieve self-locking through the threads, enabling the limiting plate 13 to move synchronously with the external threaded sleeve 12 along the axial direction of the main shaft 11, improving the assembly efficiency of the limiting plate 13. In other embodiments, the limiting plate 13 can also be welded to the outer circumferential surface of the external threaded sleeve 12 to ensure a fixed connection between the limiting plate 13 and the external threaded sleeve 12.

[0037] like Figure 6 and Figure 7 As shown, the outer circumference of the main shaft 11 is provided with a first tangent plane 111 along the axial direction, and the inner ring of the gear disk 2 is provided with a second tangent plane 22 along the axial direction. The first tangent plane 111 and the second tangent plane 22 are fitted together. Through the above arrangement, the cross-section of the inner ring of the gear disk 2 and the cross-section of the main shaft 11 are both non-circular cross-sections. When the gear disk 2 is fitted onto the main shaft 11, the first tangent plane 111 of the gear disk 2 is fitted with the second tangent plane 22 of the main shaft 11, preventing the gear disk 2 from rotating relative to the main shaft 11 along the axial direction, thus achieving circumferential limitation of the gear disk 2, so that the gear disk 2 can only move up and down along the axial direction of the main shaft 11.

[0038] Specifically, the main shaft 11 has two first tangent planes 111 symmetrically arranged circumferentially, and the inner ring of the gear disk 2 has two corresponding second tangent planes 22. The two first tangent planes 111 and the two second tangent planes 22 are fitted one-to-one to ensure that the gear disk 2 is circumferentially limited by the main shaft 11. In other embodiments, the main shaft 11 may also have multiple first tangent planes 111, as long as the cross-section of the main shaft 11 is a non-circular cross-section, and the inner ring of the gear disk 2 is adjusted adaptively.

[0039] In this embodiment, the elastic element 3 is a spring, which is sleeved on the main shaft 11. One end of the spring abuts against the limiting plate 13, and the other end abuts against the end of the gear plate 2 away from the second anti-loosening tooth 21. The use of a spring for the elastic element 3 facilitates its installation on the main shaft 11, ensuring reliable assembly and stable elastic recovery performance. Furthermore, the spring's simple and compact structure reduces installation space requirements, improving assembly efficiency. In other embodiments, the elastic element 3 can also be a spring sheet or other elastic components, which are not specifically limited here.

[0040] like Figure 3 As shown, when the temple 20 is in the folded position or unfolded to 90°, the second anti-loosening tooth 21 of the spring-driven gear 2 is locked into the groove of the locking ring 53. Figure 4As shown, when the temples 20 are extended to other angles relative to the frame 10, the locking ring 53 rotates synchronously with the extension of the temples 20. The first anti-loosening tooth 531 in the locking ring 53 engages with the corresponding second anti-loosening tooth 21 in the gear disc 2, pushing the gear disc 2 to rise axially. The spring is further compressed and applies a reaction force to the locking ring 53 through the gear disc 2, thereby pushing the temples 20 to flip inward, thus clamping the two temples 20 tightly to the user's head and preventing the glasses from falling off due to insufficient clamping force. The clamping force of the temples 20 can be adjusted by screwing on the external threaded sleeve 12 to prevent the temples 20 from being too loose or too tight. This allows the clamping force of the temples 20 to be adjusted according to the user's different head circumference, ensuring that the temples 20 are clamped tightly without causing pain to the user, thus improving the versatility and user experience of the glasses.

[0041] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
