Description

Technical Field

[0001] This utility model belongs to the field of eyeglass frame technology, and more specifically, it relates to an eyeglass frame with a folding and locking function. Background Technology

[0002] Throughout the history of eyeglasses development, while traditional eyeglass frames have met basic wearing needs, they have many shortcomings in terms of portability and ease of use. With the accelerating pace of life and the increasing demand for portable items, the inconveniences of traditional eyeglass frames have become increasingly apparent.

[0003] Traditional eyeglass frames have a relatively simple folding structure, typically allowing only unidirectional folding of the temples, and lacking an effective locking mechanism after folding. This means that the folding parts can easily unfold accidentally during transport, potentially damaging the glasses and scratching the lenses or other items. For example, when placing glasses in confined spaces such as pockets or bags, the unlocked folding temples may open due to body movement or collisions with other objects, making the glasses unstable.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an eyeglass frame with a folding locking function to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an eyeglass frame with a folding and locking function, comprising two frames, two first temples, and two second temples. The two frames are rotatably mounted together by screws. The two first temples are respectively rotatably mounted at both ends of the two frames by screws. The two second temples are also respectively mounted at the other ends of the two first temples by screws. Rotating teeth are fixedly mounted at both ends of the first temples by screws. Elastic components are provided in the frames and the second temples near the ends of the first temples. The elastic components are located on one side of the rotating teeth. The two ends of the elastic components are respectively provided with a reset mechanism and a locking mechanism. The reset mechanism and the locking mechanism are respectively disposed in the frames and the second temples.

[0008] Furthermore, the middle part of the rotating tooth is arc-shaped, and the space between the teeth is also arc-shaped.

[0009] Furthermore, the elastic component includes a sliding rod, which is disposed on one side of the rotating tooth and is slidably mounted on the mirror frame. The mirror frame has an internal mounting groove, and a slider is slidably mounted at one end of the sliding rod within the inner cavity of the mounting groove.

[0010] Furthermore, a spring is fixedly installed at the other end of the slider, and the other end of the spring is fixedly installed on the mounting groove. Trapezoidal grooves and slots are respectively provided at both ends of the slider.

[0011] Furthermore, the reset mechanism includes a first threaded rod, which is threadedly mounted on the mirror frame, and a rotating block is fixedly mounted on one end of the first threaded rod.

[0012] Furthermore, a trapezoidal locking block is rotatably mounted at the other end of the first threaded rod and inside the mirror frame. A sliding groove is provided inside the mirror frame for the trapezoidal locking block to slide in, and the trapezoidal locking block slides in conjunction with the trapezoidal groove.

[0013] Furthermore, the snap-fit ​​mechanism includes a second threaded rod, which is threadedly mounted on the mirror frame. One end of the second threaded rod is fixedly mounted with a hand-operated block, and the other end of the second threaded rod is snapped into the slot.

[0014] This utility model has the following beneficial effects:

[0015] 1. When the glasses are folded to a predetermined angle, the contact point between the elastic component and the rotating tooth is located between the two teeth of the rotating tooth. Then, the locking mechanism is rotated by hand, causing the locking mechanism to move towards the elastic component and lock the elastic component. Subsequently, the elastic component uses the arc between the two teeth of the rotating tooth to lock the rotating tooth, and then the rotating tooth locks the first temple. Since both the elastic component and the locking mechanism are located inside the frame, the frame and the first temple are also locked, ensuring that the frame will not change after being adjusted to a suitable position during use, thus ensuring wearing comfort and stability.

[0016] 2. The user of this utility model can manually rotate the rotating block, which drives the first threaded rod to rotate on the frame. The first threaded rod will generate linear displacement along the thread direction. As the first threaded rod moves, the inclined surface of the trapezoidal locking block will apply force to the inclined surface of the trapezoidal groove of the slider, pushing the slider to move closer to the sliding rod in the mounting groove, thereby driving the sliding rod to move its position. The sliding rod will push the rotating teeth to rotate, and then the first temple will also rotate until the sliding rod enters between the two teeth on the rotating teeth. At this time, the locking groove of the slider can be accurately aligned with the second threaded rod. The second threaded rod can then be locked into the locking groove by rotating the hand-operated block, completing the locking of the folded state of the eyeglass frame and ensuring that the eyeglass frame can stably maintain this state after folding.

[0017] 3. In the entire folding process of the glasses, the frames first rotate relative to each other, then the first temple folds towards the frame, and then the second temple can also rotate around the screw connected to the first temple, further folding towards the frame, so that the glasses present a relatively compact folded shape, which is convenient to carry and store.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 utility model.

[0030] For the first embodiment, please refer to... Figures 1-6 As shown, this utility model is an eyeglass frame with a folding and locking function, including two frames 1, two first temples 2 and two second temples 3. The two frames 1 are rotatably mounted together by screws. The two first temples 2 are respectively rotatably mounted at both ends of the two frames 1 by screws. The two second temples 3 are also respectively mounted at the other ends of the two first temples 2 by screws.

[0031] The two frames 1 are connected by screws, allowing them to rotate relative to each other around the axis of the screws, changing their angle. Two first temples 2 are screwed to the ends of the two frames 1, also allowing for flexible rotation of the first temples 2 relative to the frames 1. Two second temples 3 are screwed to the other ends of the two first temples 2, allowing them to rotate relative to the first temples 2. During the folding process, the frames 1 rotate relative to each other firstly, then the first temples 2 fold towards the frames 1. Subsequently, the second temples 3 can also rotate around the screws connected to the first temples 2, further folding towards the frames 1. This results in a compact folded shape for easy carrying and storage. When the glasses need to be used, the reverse order is followed: first, the second temples 3 are unfolded outwards from their folded state, then the first temples 2 are unfolded accordingly. Finally, the frames 1 are adjusted to the appropriate position, and the glasses are returned to a normal, wearable state.

[0032] Example 2: Based on the above solution, although it is possible to fold the various parts of the eyeglass frame, we found in daily use that due to the lack of locking of the various parts of the eyeglass frame, the position of each part is not stable enough. During wearing, the position of each part will change due to slight shaking or small head movements. For example, when the user lowers or turns their head, the temples may shift inward or outward, causing the glasses to not fit the face well.

[0033] Specifically, both ends of the first temple 2 are fixed with rotating teeth 5 by screws. The frame 1 and the second temple 3 are provided with elastic components 402 near the two ends of the first temple 2. The elastic components 402 are located on one side of the rotating teeth 5. The two ends of the elastic components 402 are respectively provided with a reset mechanism 403 and a snap-fit ​​mechanism 404. The reset mechanism 403 and the snap-fit ​​mechanism 404 are respectively disposed in the frame 1 and the second temple 3. The middle part of the teeth of the rotating teeth 5 is arc-shaped, and the teeth are also arc-shaped.

[0034] The rotating teeth 5 at both ends of the first temple 2 are fixedly installed by screws. The arc shape in the middle and between the teeth can effectively reduce the frictional resistance with the elastic component 402 when the eyeglass frame is folded or unfolded, making the rotation process smoother and reducing the possibility of jamming and wear. When the frame 1 and the first temple 2, and the first temple 2 and the second temple 3 rotate relative to each other around the rotating teeth 5, the arc-shaped teeth can adaptively adjust the contact angle to ensure that the force transmission between the components is uniform and stable. Whether it is the angle change during folding or the reset operation during unfolding, it can be achieved accurately and easily.

[0035] In this solution, since both the frame 1 and the second temple 3 are equipped with an elastic component 402, a reset mechanism 403, and a locking mechanism 404, and their locking mechanisms are exactly the same, the following example illustrates how the frame 1 and the first temple 2 are folded and locked: When the first temple 2 needs to be folded, the user manually rotates the first temple 2. At this time, the rotating teeth 5, which are fixed at both ends of the first temple 2 by screws, will also be rotated. The rotation of the rotating teeth 5 causes the teeth on them to rotate as well. Since the middle of the teeth of the rotating teeth 5 is arc-shaped, and the teeth are also arc-shaped, the teeth on the rotating teeth 5 will compress the elastic component 402, causing it to deform and store elastic potential energy. During the rotation of the rotating teeth 5, the elastic potential energy inside the elastic component 402 causes the elastic component 402 to... 02 is always in contact with the rotating tooth 5. When folded to the predetermined angle, the contact point between the elastic component 402 and the rotating tooth 5 is located between the two teeth of the rotating tooth 5. Then, the locking mechanism 404 is rotated by hand, causing the locking mechanism 404 to move towards the elastic component 402 and lock the elastic component 402. Subsequently, the elastic component 402 uses the arc between the two teeth of the rotating tooth 5 to lock the rotating tooth 5, and then the rotating tooth 5 locks the first temple 2. Since the elastic component 402 and the locking mechanism 404 are both located inside the frame 1, the frame 1 and the first temple 2 are also locked, ensuring that the eyeglass frame will not change after being adjusted to a suitable position during use, thus ensuring wearing comfort and stability.

[0036] More specifically, the elastic component 402 includes a sliding rod 4021, which is disposed on one side of the rotating tooth 5. The sliding rod 4021 is slidably mounted on the mirror frame 1. The mirror frame 1 has an installation groove 101 inside. A slider 4022 is slidably mounted on one end of the sliding rod 4021 and inside the installation groove 101.

[0037] A spring 4023 is fixedly installed at the other end of the slider 4022, and the other end of the spring 4023 is fixedly installed on the mounting groove 101. A trapezoidal groove 4024 and a slot 4025 are respectively opened at both ends of the slider 4022.

[0038] The snap-fit ​​mechanism 404 includes a second threaded rod 4041, which is threadedly mounted on the mirror frame 1. A hand-operated block 4042 is fixedly mounted on one end of the second threaded rod 4041, and the other end of the second threaded rod 4041 is snapped into the slot 4025.

[0039] When the first temple 2 needs to be folded, the user manually rotates the first temple 2. At this time, the first temple 2 drives the rotating tooth 5 to rotate, and the rotating tooth 5 interacts with the sliding rod 4021. Since the sliding rod 4021 can slide within the mounting groove 101 of the frame 1, when the teeth of the rotating tooth 5 approach the sliding rod 4021, it will push the sliding rod 4021. The sliding rod 4021 drives the slider 4022 to move within the mounting groove 101. The movement of the slider 4022 will compress the spring 4023. As the rotating tooth 5 rotates, the sliding rod 4021 will be pushed between the two teeth of the rotating tooth 5 by the elastic force of the spring 4023, thereby locking the position of the rotating tooth 5. After the eyeglass frame folding operation is completed, it needs to be locked to prevent accidental unfolding. At this time, the user manually rotates the hand-operated block 4042, which drives the second threaded rod 4041 to rotate threadedly on the frame 1. The second threaded rod 4041 moves linearly along the thread direction. When the sliding rod 4021 is positioned between two teeth of the rotating tooth 5, the slot 4025 of the slider 4022 aligns with one end of the second threaded rod 4041, and the second threaded rod 4041 engages with the slot 4025, thereby fixing the position of the slider 4022. This restricts the movement of the sliding rod 4021 and the rotating tooth 5 connected to the slider 4022, thus locking the eyeglass frame in its folded state. When it is necessary to unfold the eyeglass frame, the hand-operated block 4042 is rotated in the opposite direction, causing the second threaded rod 4041 to disengage from the slot 4025, releasing the restriction on the slider 4022.

[0040] Example 3: The reset mechanism 403 includes a first threaded rod 4031, which is threadedly mounted on the mirror frame 1, and a rotating block 4032 is fixedly mounted on one end of the first threaded rod 4031.

[0041] The other end of the first threaded rod 4031 is rotatably mounted with a trapezoidal locking block 4033 located inside the mirror frame 1. The mirror frame 1 has a sliding groove for the trapezoidal locking block 4033 to slide in, and the trapezoidal locking block 4033 slides in cooperation with the trapezoidal groove 4024.

[0042] After the folding operation is completed, the sliding rod 4021 may be in a special position, such as being located in the middle of the teeth of the rotating tooth 5 or not located between two teeth. This causes the second threaded rod 4041 to fail to accurately trigger the slider 4022 to restrict it, meaning it cannot properly engage with the slot 4025 to lock the folded state. In this case, the position of the slider 4022 needs to be adjusted to achieve a lockable state. The user can manually rotate the rotating block 4032, which drives the first threaded rod 4031 to rotate threadedly on the frame 1. Since the first threaded rod 4031 and the frame 1 are threadedly engaged, the first threaded rod 4031 will generate linear displacement along the thread direction during rotation. Meanwhile, the trapezoidal locking block 4033 at the other end of the first threaded rod 4031 slides in the sliding groove of the frame 1 and slides in cooperation with the trapezoidal groove 4024 of the slider 4022. As the first threaded rod 4031 moves, the inclined surface of the trapezoidal locking block 4033 applies force to the inclined surface of the trapezoidal groove 4024 of the slider 4022, pushing the slider 4022 to move closer to the sliding rod 4021 within the mounting groove 101. This, in turn, causes the sliding rod 4021 to move, pushing the rotating tooth 5 to rotate. Subsequently, the first temple 2 will also rotate until the sliding rod 4021 enters between two teeth on the rotating tooth 5. At this point, the locking groove 4025 of the slider 4022 can be accurately aligned with the second threaded rod 4041, creating conditions for locking. After this, the second threaded rod 4041 can be locked into the locking groove 4025 by rotating the hand-operated block 4042, completing the locking of the folded state of the eyeglass frame and ensuring that the eyeglass frame can stably maintain this state after folding.
