Description

Technical Field

[0001] This utility model relates to the field of eyeglass accessories, and in particular to a hinge component that connects the eyeglass frame and the temples. Background Technology

[0002] The frames and temples of eyeglasses are generally connected by a hinge structure. The hinge structure used in eyeglasses on the market is quite common, and is only fixed by a single bolt. The angle of rotation of the temples relative to the frames is relatively fixed, generally between 0 and 90 degrees.

[0003] However, when people with large head circumferences wear glasses, the temples cannot rotate at a large angle, and the distance between the two temples is smaller than the wearer's head circumference. As a result, the glasses frame will be deformed when worn, and the two temples will clamp the wearer's head tightly, causing the wearer to experience strong discomfort. Utility Model Content

[0004] This application provides a hinge component for connecting the frame and temple of a pair of glasses, which has the characteristics of a large range of motion, good adaptability, and excellent compressive strength.

[0005] The hinge component for connecting the eyeglass frame and temples provided in this application adopts the following technical solution:

[0006] A hinge component connecting a mirror frame and temples includes a first connector connected to the mirror frame and a second connector connected to the temples. A pull rod spring is mounted on the second connector, with the spring body end of the pull rod spring connected to the second connector. A mating groove is formed on the first connector, and the hook-shaped end of the pull rod spring hooks into the mating groove to form a hinge structure, allowing the second connector to rotate left and right relative to the first connector. The end of the first connector away from the mirror frame abuts against the second connector, and an arc surface is formed on the end of the first connector away from the mirror frame. When the second connector rotates at an angle greater than 90° relative to the first connector, the second connector moves to abut against the arc surface and stretches the pull rod spring.

[0007] By adopting the above technical solution, the opening angle of the temples is increased, making it easier for people with large head circumferences to wear glasses. When wearing glasses with the above-mentioned hinge, if the wearer has a large head circumference, the temples will be stretched open, causing the rotation angle of the second connector relative to the frame to be greater than 90°. At this time, the pull rod spring is stretched, and the pull rod spring will generate a rotational force on the second connector and the temples, driving the second connector and the temples to rotate back towards the frame. Under the influence of this rotational force, the two temples will generate a clamping force on the wearer's head. This clamping force is much smaller than the clamping force generated by the deformation of the glasses, so it will not cause discomfort to the wearer. At the same time, the existence of this clamping force will also improve the stability of the glasses when worn.

[0008] Preferably, the end of the first connector away from the frame is provided with a limiting plane. When the temple is in the retracted state, the second connector abuts against the limiting plane, the pull rod spring is stretched by force, and the limiting plane restricts the second connector from rotating relative to the first connector.

[0009] By adopting the above technical solution, the temples being in the retracted state means that when the glasses are not in use, the two temples are folded together and close to the frame. The setting of a limiting plane prevents the two temples from unfolding due to the rebound force of the pull rod spring when folded, ensuring the stability of the temples in the retracted state.

[0010] Preferably, the second connector has a mounting hole, the pull rod spring is disposed in the mounting hole, a limiting sleeve is fitted on the pull rod spring, the limiting sleeve is located in the mounting hole, and a limiting block is provided on the inner wall of the mounting hole, the limiting block is located on the side of the limiting sleeve close to the first connector.

[0011] By adopting the above technical solution, the maximum extension distance of the pull rod spring is limited, preventing the connection between the pull rod spring and the connecting block 2 from breaking under force.

[0012] Preferably, the limiting block is formed by stamping.

[0013] By employing the above technical solution, the outer wall of the connecting part two is impacted by a stamping machine, causing the hole wall of the mounting hole to bulge out to form a limiting block. This forming method is convenient and quick, and will not interfere with the installation of the pull rod spring.

[0014] Preferably, the connecting member one includes a block one and a block two, with the block two located between the block one and the connecting member two; the block one is provided with a mating block, and the mating groove is formed on the mating block; the block two is provided with a relief groove one, and the mating block extends into the relief groove one; the block two is provided with a relief groove two, which communicates with the relief groove one, and the hook-shaped end of the pull rod spring extends into the relief groove two; the block one can rotate up and down relative to the block two, and when the block one rotates relative to the block two, it will stretch the pull rod spring.

[0015] By adopting the above technical solution, the frame can rotate up and down relative to the temples. When the frame or temples are subjected to external forces in the up and down direction, block one will rotate relative to block two and stretch the tension spring to release the force, thereby improving the pressure resistance of the glasses.

[0016] Preferably, two clearance arc surfaces are provided on the end of the second block near the first block, and the two clearance arc surfaces are arranged opposite to each other on the second block.

[0017] By adopting the above technical solution, the opening of the lateral arc surface ensures that block two will not collide with block one when block one rotates.

[0018] Preferably, a threaded hole 1 is provided on the end of the first block away from the second block, and a threaded hole 2 is provided on the end of the second connector away from the second block.

[0019] By adopting the above technical solution, it is convenient to connect the first block to the frame and to connect the second connector to the temple.

[0020] Preferably, the mating block protrudes at one end facing the second connector to form an anti-detachment block.

[0021] By adopting the above technical solution, the anti-detachment block prevents the hook end from disengaging from the mating groove when the pull rod spring rotates.

[0022] The main technical effects of this utility model are reflected in the following aspects:

[0023] 1. This utility model can improve the rotation angle of the temples while also meeting the requirement of stable eyeglass wearing;

[0024] 2. This invention enables the frame and temples to rotate relative to each other in four directions (up, down, left, and right), thereby improving the pressure resistance of the glasses. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0035] Reference Figures 1-5 This embodiment provides a hinge component connecting a mirror frame and a temple, including a connector 1 connected to the mirror frame 4 and a connector 2 connected to the temple 5. Connector 1 includes a block 14 and a block 2 15, located between block 14 and connector 2. A threaded hole 142 is provided on the end of block 14 away from connector 2, for connecting to the mirror frame 4. Two clearance arc surfaces 153 are provided on the end of block 2 15 near block 14, respectively located on opposite sides of the end of block 2 15 near block 14.

[0036] Reference Figures 2-5 A mating block 141 is formed on one end of block 14 near connector 2, and a mating groove 11 is provided on the mating block 141. A clearance groove 151 is provided on block 2, and the mating block 141 extends into the clearance groove 151, with the mating groove 11 located within the clearance groove 151.

[0037] Reference Figure 2 , Figure 6 and Figure 7 A threaded hole 24 is provided on the end of connector 2 away from block 2 15. A mounting hole 21 is provided on the end face of connector 2 near block 2 15 along the length of block 2 15. A pull rod spring 3 is placed in the mounting hole 21. The hook-shaped end of the pull rod spring 3 is located outside block 2 15, and the spring body end of the pull rod spring 3 is located inside the mounting hole 21 and fixed to connector 2.

[0038] Reference Figure 1 , Figure 2 , Figure 6 and Figure 8The second block 15 has a relief groove 152. The hook-shaped end of the pull rod spring 3 extends into the relief groove 152 and hooks into the mating groove 11. The pull rod spring 3 and the mating groove 11 form a hinge structure, which allows the second connector 2 to rotate relative to the second block 15 in the opening and closing plane of the glasses, and the first block 14 to rotate relative to the second block 15 in a direction perpendicular to the opening and closing plane of the glasses.

[0039] Reference Figure 2 and Figure 7 The end of block 2 15 away from block 1 14 abuts against connector 2 2, and an arc surface 12 is provided on this end. When connector 2 2 rotates at an angle greater than 90° relative to block 2 15, connector 2 2 moves to abut against arc surface 12 and stretches the pull rod spring 3.

[0040] Reference Figure 2 and Figure 7 When glasses using the aforementioned hinge are worn, if the frame 4 or temple 5 is subjected to a force perpendicular to the opening and closing plane of the temple 5, block 14 will rotate relative to block 2 15 and stretch the pull rod spring 3 to release the force. If the wearer has a large head circumference, the temple 5 will be spread open, causing the rotation angle of connector 2 relative to block 2 15 to be greater than 90°. At this time, the pull rod spring 3 is stretched, and the pull rod spring 3 will generate a rotational force on connector 2 2 and temple 5, driving connector 2 2 and temple 5 to rotate in the retracting direction. Under the influence of this rotational force, the two temples 5 will generate a more suitable clamping force on the wearer's head, improving the stability of the glasses when worn.

[0041] Reference Figure 1 , Figure 2 , Figure 5 and Figure 8 A limiting plane 13 is also provided on the end of block 2 15 away from block 1 14. This limiting plane 13 is symmetrically arranged with arc surface 12. When the temples 5 are in the retracted state (referring to the state where the two temples 5 are folded together and close to the frame 4 when the glasses are not in use), the connecting piece 2 abuts against the limiting plane 13, and the pull rod spring 3 is stretched. The limiting plane 13 is used to limit the retracted rotation of the connecting piece 2 2 relative to block 2 15, so that the two temples 5 will not unfold due to the rebound force of the pull rod spring 3 when they are folded together, thus ensuring the stability of the temples 5 in the retracted state.

[0042] Reference Figure 7A limiting sleeve 22 is fitted onto the pull rod spring 3, and the limiting sleeve 22 is located inside the mounting hole 21. Two limiting blocks 23 are provided on the inner wall of the mounting hole 21, both of which are located on the side of the limiting sleeve 22 closest to the second block 15. The limiting blocks 23 are formed by stamping: after the pull rod spring 3 is assembled with the mating groove 11, the outer wall of the second connector 2 is impacted by a stamping machine, causing the hole wall of the mounting hole 21 to bulge out to form the limiting block 23. Through the cooperation of the limiting block 23 and the limiting sleeve 22, the maximum axial extension of the pull rod spring 3 is limited, preventing the connection between the pull rod spring 3 and the second connector 2 from breaking due to excessive force when the pull rod spring 3 is stretched too far.

[0043] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
