Description

Technical Field

[0001] The utility model relates to the technical field of metal glasses, in particular to a pair of high-strength metal glasses. Background Art

[0002] Metal glasses are popular among consumers for their aesthetics and durability. However, the connection between the frame and the temples has always been a weak link in the structure of metal glasses. Because the temples are usually designed to rotate inward toward the frame, during daily use, the glasses are easily affected by various external factors (such as accidental collisions, accidental pulling, and improper force when putting on and taking off).

[0003] This outward force often causes excessive stress on the connection between the eyeglass frame and the temples, which in turn causes breakage and damage. Once the connection is damaged, the glasses cannot be worn and used normally, which not only causes economic losses to the user, but also affects their normal work and life. In the existing technology, the structural design of the connection mostly focuses on simple hinged fixation, lacks an effective buffering and protection mechanism to deal with the outward force, and is difficult to meet users' requirements for durability and reliability of glasses. Therefore, a high-strength metal glasses is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide high-strength metal glasses to solve the problem that the outward force often causes the connection between the glasses frame and the glasses legs to be subjected to excessive stress, which in turn causes breakage and damage. Once the connection is damaged, the glasses will not be able to be worn and used normally. In the prior art, the structural design of the connection mostly focuses on simple hinged fixation, lacks an effective buffering and protection mechanism to deal with the outward force, and is difficult to meet users' requirements for durability and reliability of glasses.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The cam is fixedly mounted on the side panel with the support frame, and the cam is fixedly mounted on the side panel with an cam interlocking with the upper and lower ends of the cam interlocking with the lower ends of the cam interlocking with the lower ends of the cam interlocking with the lower ends of the cam interlocking with the lower ends of the cam interlocking with the upper ends of the cam interlocking with the upper ends of the cam interlocking.

[0007] As a further optimized content of the present invention, the shape of the reed is V-shaped, and there is a gap between the top and bottom ends of the reed and the mirror rod.

[0008] As a further optimization of the present invention, the height of the supporting bevel block is adapted to the height of the spring sheet, the initial limit slot is located on one side of the front end face of the supporting bevel block, the guide groove is located on the other side of the front end face of the supporting bevel block, and the mounting groove is located at the center of the inner side of the guide groove.

[0009] As a further optimization of the present invention, there are multiple friction plates, and the multiple friction plates are arranged in an arc shape, with a gap left between every two adjacent friction plates.

[0010] As a further optimization of the present invention, the outer side of the friction protrusion is in an arc-shaped structure, the height of the friction protrusion is adapted to the height of the mounting groove, and the friction protrusion is in sliding fit with the friction plate.

[0011] As a further optimization of the present invention, the angle between the hinge block and the hinge seat is 90°, a movable groove for adapting the spring is provided on the inner side of the hinge block, and the connecting rod is slidably fitted in the guide groove.

[0012] As a further optimized content of the present invention, one end of the connecting seat is fixedly connected to the temple via a screw, and a gap is left between the temple and the temple rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the utility model, the durability and reliability of the glasses are effectively improved by the provision of a protective component and a supporting base mechanism. During daily wear, the limit card is inserted into the initial limit card slot to ensure a firm connection without looseness. When subjected to external force, the limit card is disengaged, the connecting rod slides, the spring elastically deforms to absorb energy, and the friction protrusions and the friction plate generate sliding friction resistance to buffer the external force. After the external force disappears, the elastic restoring force of the spring pushes the component to reset, and friction provides damping to avoid rapid rebound, and the limit card is re-engaged to restore the initial state. This design effectively avoids damage to the connection between the frame and the temples due to outward force, reduces user losses, and meets user requirements for the durability and reliability of the glasses.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0027] See also Figures 1-6 , the utility model provides a technical solution:

[0028] A pair of high-strength metal glasses, including a frame 1, the top of the frame 1 is fixedly connected to a mirror rod 2, the inner side of the mirror rod 2 is fixedly connected to a protective component 3, the outer side of the protective component 3 is hinged with a connecting seat 4, one end of the connecting seat 4 is fixedly connected to a temple 5 by a screw, and a gap is left between the temple 5 and the mirror rod 2; the protective component 3 includes a spring 31, the shape of the spring 31 is V-shaped, and the top and bottom ends of the spring 31 are both gaps between them and the mirror rod 2, the spring 31 is fixedly set on one side of the inner wall of the mirror rod 2, the front end of the inner side of the spring 31 is fixedly connected to a support base mechanism 32, the front end of the outer side of the spring 31 is fixed to a hinge block 33 by a screw, and the front end of the hinge block 33 It is fixedly connected with a connecting rod 34, the front side of the connecting rod 34 is fixedly connected with a limiting block 35, the outer wall of the connecting rod 34 is fixedly connected with a friction protrusion 36 made of titanium alloy material, and the rear end of the hinge block 33 is fixedly connected with a hinge seat 37; the support base mechanism 32 includes a supporting bevel block 321, and the front end surface of the supporting bevel block 321 is provided with an initial limiting slot 322, a guide groove 323 and an installation slot 324, the depth of the initial limiting slot 322 is 1.5 mm, and the inner side of the installation slot 324 is fixedly connected with a friction plate 325 made of nitrile rubber material; the limiting block 35 is engaged with the initial limiting slot 322, and the hinge seat 37 is hinged to the connecting seat 4.

[0029] As a further implementation of this solution, the height of the support bevel 321 is adapted to the height of the spring 31, ensuring the coordination of the mechanical cooperation between the two. The initial limit slot 322 is located on one side of the front end surface of the support bevel 321, and the guide slot 323 is located on the other side of the front end surface of the support bevel 321. The arc-shaped trajectory of the guide slot 323 has a curvature radius of 12 mm, and the mounting slot 324 is located at the center of the inner side of the guide slot 323. This layout enables the connecting rod 34 to move along the preset trajectory of the guide slot 323 when subjected to force, avoiding deviation.

[0030] As a further implementation of this solution, a plurality of friction plates 325 are provided. The plurality of friction plates 325 are arranged in an arc shape, with a gap between each two adjacent friction plates 325. The outer side of the friction protrusion 36 is an arc-shaped structure. The height of the friction protrusion 36 matches the height of the mounting groove 324. The friction protrusion 36 and the friction plate 325 are in sliding engagement with each other to ensure that stable friction resistance is maintained throughout the entire sliding process of the connecting rod 34, effectively buffering external force impacts. At the same time, appropriate damping is provided during the reset process to prevent rapid rebound.

[0031] As a further implementation of this solution, the angle between the hinge block 33 and the hinge seat 37 is 90°, and a movable groove 38 for adapting the spring 31 is opened on the inner side of the hinge block 33, and the connecting rod 34 slides with the guide groove 323. The movable groove 38 is provided to provide sufficient movable space for the spring 31 during the deformation process.

[0032] Working process: When the spring 31 is in a naturally stretched state, the limit card block 35 is tightly inserted into the initial limit card slot 322, and the initial position of the hinge block 33 is locked to ensure that there is no looseness during daily wear. When the connecting seat 4 is subjected to an outward lateral force, such as being collided or squeezed, the external force is transmitted to the hinge block 33 through the hinge seat 37, forcing the connecting rod 34 to apply a shear force to the limit card block 35. When the external force exceeds the friction threshold of the initial limit card slot 322, the limit card block 35 is disengaged from the initial limit card slot 322, releasing the initial constraint, and the connecting rod 34 slides along the inclined surface of the supporting inclined block 321 toward the guide groove 323. During the sliding process, the connecting rod 34 exerts a shear force on the supporting inclined block 321. The inclined block 321 applies pressure, and the spring 31 has good elasticity, forcing the spring 31 to produce elastic compression deformation. As the connecting rod 34 moves, the friction protrusion 36 is driven to move synchronously. The friction protrusion 36 slides into the installation groove 324 synchronously and contacts the arc-shaped friction plate 325 to generate sliding friction resistance, thereby producing a damping effect. When the external force disappears, the elastic restoring force of the spring 31 pushes the hinge block 33 back along the original path. At the same time, the reverse stroke friction between the friction protrusion 36 and the friction plate 325 provides reset damping to avoid impact caused by rapid rebound. The limit block 35 is then re-engaged in the initial limit slot 322 and restored to the initial stable state.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
