Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and in particular to an anti-vibration eyeglass frame for outdoor sports. Background Technology

[0002] Eyeglasses are lenses encased in frames and worn in front of the eyes to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct various vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, and strabismus. They consist of lenses and frames, and are generally classified into four types: nearsighted glasses, farsighted glasses, presbyopia glasses, and astigmatism glasses. Specialized eyeglasses are also available for viewing 3D or virtual reality images. Other types of eyeglasses include safety goggles, sunglasses, and swimming goggles, providing various forms of eye protection.

[0003] Existing shock-resistant glasses, such as the smart glasses with good shock resistance and waterproofing disclosed in publication number CN207636859U, use a slot in the middle of the outer wall on the side where the side seal connects to the lens, with several shock-absorbing pads embedded inside the slot. This gives the lens good shock resistance after installation. However, most shock-resistant glasses frames use a fixed temple design, lacking an effective adjustment mechanism, which prevents the temples from adapting to the user's face shape. For users with wider faces or larger head circumferences, prolonged wear can cause the temples to deform due to continuous outward expansion force, affecting wearing comfort, loosening the frame structure, reducing shock resistance, and ultimately shortening the lifespan of the glasses. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing shock-resistant eyeglass frames, which mostly employ fixed temple designs and lack effective adjustment mechanisms, resulting in the temples being unable to adapt to the user's face shape. For users with wider faces or larger head circumferences, prolonged wear can cause the temples to undergo plastic deformation due to continuous outward expansion forces, affecting wearing comfort, loosening the frame structure, reducing shock resistance, and ultimately shortening the lifespan of the eyeglasses. Therefore, this invention proposes a shock-resistant eyeglass frame for outdoor sports.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An outdoor sports shock-resistant glasses frame includes a shock-resistant glasses body. A shock-absorbing groove is provided at the nose pad of the shock-absorbing glasses body, and a shock-absorbing component is located in the groove. A movable opening is provided within the frame of the shock-resistant glasses body, and a screw is rotatably installed in the movable opening. Knobs are rotatably installed on both sides of the shock-resistant glasses body. A slider is provided on the screw, and a connecting frame is fixedly installed at the extension end of the slider. The connecting frame is connected to the temples via hinges, and a locking mechanism is provided inside the knobs.

[0007] Preferably, the damping component includes a spring, a mounting block, and a silicone pad. The mounting block is slidably disposed in the damping groove. One end of the spring is fixedly connected to the inner wall of the damping groove, and the other end of the spring is fixedly connected to the side of the mounting block located in the damping groove. The silicone pad is fixedly installed on the side of the mounting block away from the damping groove.

[0008] Preferably, a waterproof pad is fixedly provided on the side of the connecting frame near the shock-absorbing glasses body, and a sliding opening is provided on the side of the shock-absorbing glasses body near the connecting frame.

[0009] Preferably, the connecting frame is L-shaped, and the slider slides in conjunction with the sliding opening.

[0010] Preferably, the locking mechanism includes a rotating cover, a torsion spring, an arc-shaped opening, a locking rod, a limiting block, an arc-shaped groove, and a stop bar. The rotating cover is slidably disposed within the knob, one end of the torsion spring is fixedly disposed within the knob, the arc-shaped opening is disposed on the side of the knob near the shock-absorbing glasses body, the locking rod is fixedly disposed on the rotating cover, the limiting block is fixedly disposed on the end of the locking rod away from the rotating cover, the arc-shaped groove is disposed on both sides of the shock-absorbing glasses body, and the stop bar is fixedly disposed in the arc-shaped groove.

[0011] Preferably, the other end of the torsion spring is fixedly mounted on the screw-on cover, and a pair of arc-shaped openings, locking rods, limiting blocks, and arc-shaped grooves are provided, with the locking rods slidingly engaging with the arc-shaped openings and arc-shaped grooves respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In use, this utility model allows users to adjust the opening angle of the temples by rotating a knob through the linkage structure of the screw, slider, and connecting frame, making the frame flexibly adaptable to users with different head circumferences or face shapes. This design avoids the plastic deformation problem caused by long-term outward expansion force in traditional fixed temples, significantly extending the service life of the glasses.

[0014] 2. When in use, the shock-absorbing component at the nose pad can effectively absorb the impact force during movement and reduce the pressure on the bridge of the nose; at the same time, the temples and the connecting frame are connected by hinges, and with the movement adjustment of the slider, the external force during wearing is further dispersed, improving shock resistance and comfort.

[0015] 3. When using this utility model, the torsion spring and locking rod structure inside the knob can automatically fix the position of the temples after adjustment, preventing the temples from loosening or sliding due to vibration during movement, and ensuring stable wearing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-6 An outdoor sports shockproof glasses frame includes a shockproof glasses body 1. The nose pad of the shockproof glasses body 1 is provided with a shock-absorbing groove 2. The shock-absorbing groove 2 contains a shock-absorbing component 3. The shock-absorbing component 3 includes a spring 11, a mounting block 12 and a silicone pad 13. The mounting block 12 is slidably disposed in the shock-absorbing groove 2. One end of the spring 11 is fixedly connected to the inner wall of the shock-absorbing groove 2, and the other end of the spring 11 is fixedly connected to one side of the mounting block 12 located in the shock-absorbing groove 2. The silicone pad 13 is fixedly installed on the side of the mounting block 12 away from the shock-absorbing groove 2.

[0025] The cushioning component 3 employs a triple-cushioning design consisting of a spring 11, a mounting block 12, and a silicone pad 13. The spring 11 provides elastic support, effectively absorbing impact during exercise; the mounting block 12 slides within the cushioning groove 2, ensuring a smooth cushioning process; and the silicone pad 13 conforms to the bridge of the nose, combining softness and anti-slip properties to significantly improve wearing comfort. This design is particularly suitable for high-intensity sports activities, effectively reducing pressure on the bridge of the nose from glasses.

[0026] The frame of the shock-resistant glasses body 1 is provided with a movable opening 4, a screw 5 is rotatably provided in the movable opening 4, and knobs 6 are rotatably provided on both sides of the shock-resistant glasses body 1. A slider 7 is provided on the screw 5, and a connecting frame 8 is fixedly provided at the extended end of the slider 7. The connecting frame 8 is connected to the temple 9 by a hinge.

[0027] The temple 9 is adjustable via a linkage design of screw 5, slider 7, and connecting bracket 8, allowing users to precisely adjust the opening angle of the temple 9. The threaded drive of screw 5 ensures a stable and reliable adjustment process, while the precise fit between slider 7 and sliding opening 15 prevents wobbling and frictional wear. The L-shaped structure of connecting bracket 8 enhances overall strength, keeping the temple 9 stable during movement.

[0028] The knob 6 is equipped with a locking mechanism 10, which includes a screw cover 16, a torsion spring 17, an arc-shaped opening 18, a locking rod 19, a limiting block 20, an arc-shaped groove 21, and a stop bar 22. The screw cover 16 is slidably disposed inside the knob 6, one end of the torsion spring 17 is fixedly disposed inside the knob 6, the arc-shaped opening 18 is disposed on the side of the knob 6 near the anti-vibration glasses body 1, the locking rod 19 is fixedly disposed on the screw cover 16, the limiting block 20 is fixedly disposed on the end of the locking rod 19 away from the screw cover 16, the arc-shaped groove 21 is disposed on both sides of the anti-vibration glasses body 1, and the stop bar 22 is fixedly disposed in the arc-shaped groove 21.

[0029] The locking mechanism 10 utilizes the combined action of a torsion spring 17 and a locking lever 19 to achieve a one-button locking function. The torsion spring 17 provides automatic rebound force, ensuring that the locking lever 19 fits tightly against the arc-shaped groove 21; the stop bar 22 prevents the locking lever 19 from dislodging, ensuring that the temple 9 is fixed in position after adjustment. This design solves the problem of traditional temples 9 being prone to loosening, making it particularly suitable for scenarios involving vigorous activity.

[0030] It should be noted that the anti-vibration glasses body 1 is existing technology in this field. It has a slot in the middle of the outer wall on the side where the side seal is connected to the lens, and several shock-absorbing pads are embedded in the slot, so that the lens has good anti-vibration performance after installation. Therefore, it will not be described in detail.

[0031] Furthermore, a waterproof pad 14 is fixedly installed on the side of the connecting frame 8 near the shock-absorbing glasses body 1, and a sliding opening 15 is provided on the side of the shock-absorbing glasses body 1 near the connecting frame 8.

[0032] Among them, a waterproof pad 14 is added to the inside of the connecting frame 8 to effectively prevent sweat or rainwater from seeping into the inside of the frame; there is sufficient distance on the right side of the connecting frame 8 so that the sliding opening 15 is still covered by the connecting frame 8 when the connecting frame 8 is moved to the outermost side.

[0033] Furthermore, the connecting frame 8 is L-shaped, and the slider 7 slides in conjunction with the sliding opening 15.

[0034] The joint between the sliding edge 15 and the slider 7 is made of corrosion-resistant material, further extending the lifespan of the frame. This design allows the glasses to maintain good performance even in humid outdoor environments.

[0035] Furthermore, the other end of the torsion spring 17 is fixedly mounted on the screw cap 16. A pair of arc-shaped openings 18, locking rods 19, limiting blocks 20, and arc-shaped grooves 21 are provided. The locking rods 19 slide in cooperation with the arc-shaped openings 18 and the arc-shaped grooves 21 respectively.

[0036] All moving parts are made of wear-resistant materials. The transmission structure of screw 5 and slider 7 undergoes special hardening treatment to ensure that no wear gaps will form during long-term use. Torsion spring 17 is made of 304 stainless steel, which is oxidation-resistant and has a long fatigue life. It has been tested to withstand more than 100,000 adjustment cycles.

[0037] Working principle:

[0038] First, the user adjusts the opening degree of the temples 9 by rotating the knobs 6 on both sides. Rotation of the knobs 6 drives the screw 5 to rotate, causing the slider 7 to slide smoothly within the moving opening 4. The slider 7, through the connecting bracket 8, drives the temples 9 to move synchronously, achieving precise adjustment of the temple opening degree. The L-shaped connecting bracket 8 design ensures structural stability during the adjustment process.

[0039] Once adjusted, the locking mechanism 10 automatically engages. When the knob 6 stops rotating, the spring force of the torsion spring 17 pushes the screw cap 16, causing the locking lever 19 to slide along the arc-shaped opening 18 and finally engage in the arc-shaped groove 21. The cooperation of the limit block 20 and the stop bar 22 ensures a secure lock and prevents accidental loosening during movement. This process achieves a one-button locking function for the temple 9 position.

[0040] When worn, the shock-absorbing component 3 at the nose bridge begins to function. The spring 11 provides elastic support through the mounting block 12, while the silicone pad 13 conforms to the bridge of the nose, working together to absorb the impact during movement. When subjected to external impact, the mounting block 12 slides within the shock-absorbing groove 2, and the spring 11 compresses to cushion the impact, effectively reducing pressure on the bridge of the nose.

[0041] A waterproof pad 14 always covers the joint between the connecting frame 8 and the shock-absorbing glasses body 1 to prevent sweat or rainwater from seeping into the internal mechanism. The precise fit between the slide 15 and the slider 7 ensures smooth adjustment, while the corrosion-resistant material guarantees durability in humid environments.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
