Description

Technical Field

[0001] The utility model relates to the technical field of hinge connection, in particular to a novel screwless elastic spectacle hinge structure and spectacles. Background Art

[0002] Spectacles are mainly composed of spectacle lenses and spectacle frames, which are used to improve eyesight, protect eyes or for decorative purposes. The main components of a spectacle frame include a frame, a nose pad, a hinge, temple arms, etc. Among them, the frame and the nose pad are usually an integral structure, the frame and the hinge are usually fixedly connected by welding, and the hinge and the temple arms are hinged.

[0003] For example, a pair of spectacles of a Chinese utility model with the publication number CN221039666U is connected through a limiting tube shaft, which can effectively prevent the hinge block from detaching from the fixed seat. The fixing screw can effectively fix the limiting tube shaft on the fixed seat and will not fall off. When the temple arms are opened and closed and rotated, the hinge block rotates relative to the limiting tube shaft. However, since the limiting tube shaft cannot rotate, the rotation of the hinge block will not affect the fixing screw. Therefore, the fixing screw will not be screwed out due to the opening and closing of the temple arms, making the installation of the fixing screw more stable and not falling off. However, such a structure still has the following several significant defects:

[0004] 1. The spectacle frame and the temple arms are fixed to each other by screws. When it is necessary to disassemble and replace the spectacle frame and the temple arms, professional tools are required to disassemble the screws between the temple arms and the spectacle frame. Such an operation is relatively cumbersome and inconvenient for people to use;

[0005] 2. In the case of strenuous exercise, the spectacles are very likely to fall off, causing the spectacles to be damaged and affecting the normal use of the spectacles. Summary of the Invention

[0055] Next, a novel screwless elastic spectacle hinge structure and spectacle provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0056] Embodiment 1:

[0057] As Figures 1 to 4 shown, the embodiment of the present application provides a novel screwless elastic spectacle hinge structure for movably connecting an external frame 1 and an external temple wire 2; including a temple wire head 3, which is arranged at the front end of the temple wire 2 and is provided with a connecting cylinder 4 thereon; a positioning member 5, which is detachably and movably connected to the connecting cylinder 4; and a mounting member 6, which is used to fixedly connect the positioning member 5 to the frame 1.

[0058] Furthermore, the limiting member 5 includes a pair of openable and closable shells 51, the lower ends of which are movably connected to the mounting member 6 through pins 52, and an opening 53 is formed between the upper ends. A deformable cavity 54 communicating with the opening 53 is formed between the pair of shells 51, and movable grooves 55 are provided on both of the pair of shells 51; an elastic reset piece 56, which is arranged between the pair of shells 51 and the mounting member 6 and is used to close the pair of shells 51; wherein, when the pair of shells 51 are in the closed state, the connecting cylinder 4 is rotatably installed in the deformable cavity 54, and the wire end 3 can slide in the pair of movable grooves 55.

[0059] Furthermore, each of the pair of shells 51 includes an arc-shaped plate 511, the lower end of which is movably connected to the mounting member 6 through a pin 52; a back plate 512, which is fixedly connected to one side plane of the arc-shaped plate 511; a side plate 513, which is fixedly connected to the outer arc surface of the arc-shaped plate 511; wherein, the pair of arc-shaped plates 511 and the pair of back plates 512 jointly define the deformable cavity 54.

[0060] Furthermore, the elastic reset piece 56 includes: a fixing portion 561, one end of which is fixedly connected to the mounting member 6; a pressing portion 562, which is fixedly connected to the other end of the fixing portion 561 and forms a 90-degree angle with the fixing portion 561; a bending portion 563, which is arranged on the pressing portion 562, and a pressing space is left between the end far from the fixing portion 561 and the mounting member 6; wherein, both ends of the pressing portion 562 are respectively abutted against the side plates 513 on the pair of shells 51.

[0061] Furthermore, the mounting member 6 includes: a mounting hole 61, which is matched with the pin 52 and is used for hinging with the pair of shells 51; a nail portion 62, and the mounting member 6 is fixed to the external spectacle frame 1 through the nail portion 62.

[0062] Furthermore, a pair of glasses provided with a novel screwless elastic spectacle hinge structure includes a spectacle frame 1, a wire 2, a stud 7 and a temple tip 8; the wire end 3 is arranged at one end of the wire 2 far from the temple tip 8, and the mounting member 6 is fixedly connected to the stud 7 through the nail portion 62.

[0063] In this embodiment of the present application, due to the adoption of the above structure, in the assembled state, the bending portion 563 will squeeze both ends of the pair of shells 51, making the opening degree between its openings 53 smaller than the diameter of the connecting cylinder 4, so that the wire 2 will not easily fall off during the opening and closing process. At the same time, the pair of arc-shaped plates 511 and the pair of back plates 512 jointly define the deformable cavity 54, and the deformable cavity 54 has the same radius as the connecting cylinder 4. The connecting cylinder 4 can rotate in the deformable cavity 54. During the rotation process, the wire 2 will drive the wire end 3 to slide in the pair of movable grooves 55;

[0064] When the user needs to replace the foot wire 2, simply press the side plate 513 at the end away from the fixing portion 561. At the same time, the side plate 513 squeezes the pressing portion 562 to cause it to deform, so that the opening degree between the openings 53 is greater than or equal to the diameter of the connecting cylinder 4. Then, pull the foot wire 2, and the connecting cylinder 4 can be easily pulled out from the deformable cavity 54 to complete the disassembly of the foot wire 2. Insert the connecting cylinder 4 of the new foot wire 2 into the deformable cavity 54, and place the foot wire head 3 in a pair of movable grooves 55. Then, release the housing 51 at the end away from the fixing portion 561. Under the elastic force of the bending portion 563, the bending portion 563 and the pressing portion 562 push the housing 51 at the end away from the fixing portion 561 again, so that the housing 51 at the end away from the fixing portion 561 rotates and resets around the pin 52, thereby making the opening degree between the openings 53 less than the diameter of the connecting cylinder 4 to complete the replacement of the foot wire 2.

[0068] Furthermore, it further includes a limiting groove 94 provided in the foot sleeve 8; and a pushing member 95 provided in the limiting groove 94, and one end of the pushing member 95 extends out of the limiting groove 94.

[0069] Furthermore, it further includes a card slot 96 equally spaced on the slider 92; and a card block 97 provided on the pushing member 95.

[0070] In this embodiment of the present application, due to the adoption of the above structure, when it is necessary to adjust the position of the connecting rope 93, by pushing the pushing member 95 upward, the card block 97 inside the foot sleeve 8 moves upward, and the card block 97 is separated from the card slot 96. At this time, the slider 92 can slide freely in the chute 91, so that the position of the connecting rope 93 can be adjusted according to the user's needs to make the connection fit the user's head better. When adjusted to the appropriate size, pull back the pushing member 95, and the card block 97 on the pushing member 95 is re-engaged with the card slot 96 on the slider 92, so that the position of the slider 92 is fixed;

[0071] The connecting rope 93 is made of elastic rubber material. The elastic rubber has good elasticity and stretchability, can closely fit the user's head to ensure that it will not slip off. At the same time, the rubber material has certain wear resistance and a relatively long service life.
