Description

Technical Field

[0001] The utility model relates to the technical field of glasses hinges, in particular to an elastic glasses hinge structure. Background Art

[0002] In the existing glasses structure, the glasses frame is directly connected to the glasses legs by screws, and there is no elastic buffer design between the glasses legs and the glasses frame.

[0003] When wearing glasses, the two temples need to be spread out. If the wearer's head width is greater than the distance between the two temples, the two temples need to be spread out to wear the glasses. In the process of spreading out the temples, since the glasses themselves do not have a dedicated deformation component, the bridge of the frame, the temples themselves, and the connection between the temples and the frame will be distorted. For glasses made of metal, long-term deformation can easily cause the temples to be welded between the frames.

[0004] In real life, if the wearer gains weight, the head will no longer fit the original glasses accurately. Replacing glasses is expensive, and wearing glasses that do not match the size affects comfort. To solve this problem, we proposed an elastic glasses hinge structure. Utility Model Content

[0005] The purpose of the present invention is to provide an elastic eyeglass hinge structure in order to solve the above problems, as described below.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model provides an elastic glasses hinge structure, comprising a glasses frame and a connecting frame, wherein the end of the connecting frame is rotatably arranged on the stump of the glasses frame;

[0008] A first groove is formed on the side of the eyeglass frame, and a titanium groove is provided on the connecting frame, and the titanium groove contacts the side wall of the first groove;

[0009] One end of the connecting frame away from the glasses frame is connected with the glasses leg through a metal spring.

[0010] By adopting the above elastic eyeglass hinge structure, when the eyeglass leg is rotated, the connecting frame and the titanium hinge follow the eyeglass leg to move, and when the titanium hinge passes through the support point of the pile head, it will deform and generate elasticity. The elastic effect of the titanium hinge can make the connecting frame automatically rebound to two states and remain stable, namely, the unfolded state and the folded state.

[0011] When the temples are in the unfolded state, the titanium splint contacts the side wall of the first groove. When the glasses are worn, the temples can continue to expand outward to adapt to the wearer's head circumference. When the temples are extended outward, the titanium splint will deform to compensate for the deformation of the connecting frame and the temples, thereby protecting the connecting frame and the temples and preventing them from being damaged due to excessive deformation.

[0012] The metal spring pieces are arranged to enable the glasses legs to be deformed relative to the connecting frame, and the glasses legs are inclined toward the ears of the wearer, and the two glasses legs cooperate to clamp the two sides of the wearer's head.

[0013] Preferably, a second groove is provided in the middle of the titanium spleen.

[0014] Preferably, the first groove has two mutually perpendicular surfaces, and one surface of the first groove contacts the side surface of the titanium spleen, and the other surface of the first groove corresponds to the end of the titanium spleen away from the temple of the glasses.

[0015] Preferably, the opposite ends of the two pile heads of the eyeglass frame serve as support points for supporting the titanium spleen, and the positions where the pile heads of the eyeglass frame contact the titanium spleen are designed to be rounded.

[0016] Preferably, the temples are tilted inwards.

[0017] Preferably, the eyeglass frame and the connecting frame are respectively provided with a wire through hole and a through hole, the internal thread of the wire through hole is connected with a screw, and the screw passes through the through hole.

[0018] Preferably, the titanium spleen and the connecting frame together form a Y-shaped structure.

[0019] Preferably, both sides of the metal spring connected to the connecting frame and the glasses leg are inclined.

[0020] The beneficial effects are:

[0021] 1. By setting the titanium spleen, the connecting frame can automatically rebound to two states and remain stable, namely the unfolded state and the folded state. After the glasses legs are naturally unfolded with the connecting frame, they can continue to expand outward to adapt to the wearer's head circumference. When the glasses legs are extended outward, the titanium spleen will deform to compensate for the deformation of the connecting frame and the glasses legs, thereby protecting the connecting frame and the glasses legs and preventing them from being damaged due to excessive deformation.

[0022] 2. The metal spring sheet is provided to enable the glasses legs to deform relative to the connecting frame, thereby further improving the degree of freedom of the entire glasses. The glasses legs are tilted toward the ears of the wearer, and the two glasses legs cooperate to clamp the two sides of the wearer's head, making the glasses more stable to wear.

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0030] See also Figure 1-Figure 3 As shown, the utility model provides an elastic eyeglass hinge structure, comprising an eyeglass frame 1 and a connecting frame 2, wherein the end of the connecting frame 2 is rotatably arranged on the stump of the eyeglass frame 1;

[0031] A first groove 5 is formed on the side of the eyeglass frame 1, and a titanium groove 4 is provided on the connecting frame 2, and the titanium groove 4 contacts the side wall of the first groove 5;

[0032] One end of the connecting frame 2 away from the eyeglass frame 1 is connected to the eyeglass leg 3 via a metal spring 6 .

[0033] As an optional implementation, a second groove 10 is provided in the middle of the titanium spleen 4. The second groove 10 serves as a thin part of the titanium spleen 4, making the titanium spleen 4 easier to deform.

[0034] The first groove 5 has two mutually perpendicular surfaces, and one surface of the first groove 5 contacts the side surface of the titanium spleen 4, and the other surface of the first groove 5 corresponds to the end of the titanium spleen 4 away from the temple 3;

[0035] The two vertical surfaces of the first groove 5 are respectively used to cooperate with the titanium spleen 4 to put the connecting frame 2 in a naturally expanded state, and to block the end of the titanium spleen 4. By blocking the end of the titanium spleen 4, the maximum expansion angle of the connecting frame 2 can be limited.

[0036] The opposite ends of the two piles of the eyeglass frame 1 serve as support points for the titanium spleen 4, and the contact positions between the piles of the eyeglass frame 1 and the titanium spleen 4 are designed to be rounded, which makes the titanium spleen 4 slide more smoothly on the piles.

[0037] The temples 3 are tilted inwards, and this design can reduce the distance between the temples 3 on both sides, so that the two temples 3 can be clamped on the wearer's head, making the glasses more stable to wear.

[0038] A wire through hole 7 and a through hole 9 are respectively provided on the eyeglass frame 1 and the connecting frame 2 . A screw 8 is connected to the inner thread of the wire through hole 7 , and the screw 8 passes through the through hole 9 .

[0039] The titanium spleen 4 and the connecting frame 2 together form a Y-shaped structure. The Y-shaped design has an outward slingshot effect, automatic rebound and two-gear positioning, and can also automatically adjust the width according to the different face sizes of the glasses wearers;

[0040] The second-stage positioning refers to the two states of the temple 3 being unfolded and folded. When the temple 3 is unfolded, the titanium rib 4 is in contact with the side wall of the first groove 5. When the temple 3 is folded, the titanium rib 4 and the head of the temple 3 face the wearer's face.

[0041] The titanium spleen 4 can make the glasses leg 3 automatically unfold. Specifically, the titanium spleen 4 slides over the support point of the pile head, recovers from deformation and then unfolds. At this time, the glasses leg 3 can be automatically unfolded for easy wearing.

[0042] Both sides of the metal spring piece 6 connected to the connecting frame 2 and the glasses leg 3 are inclined surfaces. This design can increase the connection area between the metal spring piece 6 and the connecting frame 2 and the glasses leg 3, and improve the connection stability.

[0043] With the above structure, when the temple 3 is rotated, the connecting frame 2 and the titanium beam 4 move with the temple 3. When the titanium beam 4 passes through the support point of the pile head, it will deform and generate elasticity. The elastic effect of the titanium beam 4 can make the connecting frame 2 automatically rebound to two states and remain stable, namely, the unfolded state and the folded state.

[0044] When the temple 3 is in the unfolded state, the titanium flange 4 contacts the side wall of the first groove 5. When the glasses are worn, the temple 3 can continue to expand outward to adapt to the wearer's head circumference. When the temple 3 is extended outward, the titanium flange 4 will deform to compensate for the deformation of the connecting frame 2 and the temple 3, thereby protecting the connecting frame 2 and the temple 3 and preventing the connecting frame 2 and the temple 3 from being damaged due to excessive deformation.

[0045] The metal spring sheet 6 is provided to enable the glasses leg 3 to be deformed relative to the connecting frame 2 , and the glasses leg 3 is tilted toward the ear of the wearer, and the two glasses legs 3 cooperate to clamp the two sides of the wearer's head.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
