Description

Technical Field

[0001] The utility model relates to the technical field of spectacle hinges, in particular to a spectacle hinge that can rotate 360 degrees. Background Art

[0002] As is well known, the structure of glasses includes lenses, frames, middle beams, hinges, temple arms, temple tips, nose bridges, and nose pads. The frame is used to install the lenses, the middle beam is used to connect two frames, the temple arms are installed on the frame through hinges, the temple tips are sleeved at the ends of the temple arms, the nose bridge is installed on the frame and located below the middle beam, and the nose pad is installed on the nose bridge.

[0003] Among them, the hinge used to connect the frame and the temple arm is an important component of the glasses. Since it is the most frequently used component in the glasses and often needs to cooperate with the folding and opening of the temple arms, it is also the most easily damaged component in the glasses. Moreover, the hinge also plays a decisive role in the wearing comfort of the glasses, because the temple arms are installed on the frame through the hinge, and the hinge determines the tightness of the two temple arms clamping the user's head.

[0004] Existing spectacle hinges generally include a pivot seat, a pivot block, and a connecting bolt. The pivot seat is fixed on the frame, the pivot block is fixed on the temple arm, and the pivot block is pivotally connected to the pivot seat through the connecting bolt. And, the pivot block is provided with a limiting portion that cooperates with the pivot seat. When the temple arm is opened, the pivot block can be clamped on the pivot seat through the limiting portion, so that the opened temple arm does not loosen, and the user can wear the glasses more comfortably. However, through observation, it is found that after long-term use of such glasses, the limiting function of the limiting portion will gradually fail, and the glasses will also have problems such as being not tightly worn and often falling off due to the loose and unstable temple arms, and even being completely unable to be worn. Therefore, the existing spectacle hinges have the defects of poor wearing comfort and short service life.

[0005] In view of this, the designer has deeply conceived and actively researched, improved and tried to develop the present utility model in view of the many deficiencies and inconveniences caused by the imperfect design of the above-mentioned spectacle hinge structure.

In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0023] Such as Figures 1 to 2As shown in the figure, it is a preferred embodiment of a 360-degree rotatable spectacle hinge of the present utility model. The spectacle hinge includes a first kit 1, on which there are a blind hole 11 and a connecting groove 12. The connecting groove 12 is located at the front end of the blind hole 11. At the front end of the connecting groove 12, there is a first limiting surface 13, and at the upper end of the connecting groove 12, there is a second limiting surface 14; a first spring 2, which is installed in the blind hole 11; a first movable rod 3, the tail of the first movable rod 3 passes through the first spring 2 and is provided with a baffle 31, and the head of the first movable rod 3 is provided with a first connecting ring 32, and the first connecting ring 32 is fitted in the connecting groove 12; a second kit 4, on which there is a through hole 41; a second movable rod 5, the second movable rod 5 is movably inserted into the through hole 41, there is a placement groove 51 on the second movable rod 5, and the head of the second movable rod 5 is provided with a second connecting ring 52, and the second connecting ring 52 is connected to the first connecting ring 32; a pin 6, which is installed at the front end of the second kit 4 and passes through the placement groove 51; and a second spring 7, which is fitted in the placement groove 51, and one end of the second spring 7 abuts against the pin 6.

[0024] When assembling the spectacle hinge, first put the first spring 2 on the first movable rod 3, weld the baffle 31 at the tail of the first movable rod 3, connect the second connecting ring 52 with the first connecting ring 32, place the second spring 7 in the placement groove 51, insert the second movable rod 5 into the through hole 41, install the pin 6 at the front end of the second kit 4 and pass it through the placement groove 51 to install the second movable rod 5 in the through hole 41, and install the first spring 2 in the blind hole 11. Specifically, insert the first spring 2 into the blind hole 11, and then perform stamping on the outer wall of the first kit 1 near the opening of the blind hole 11 to form a limiting portion 111 on the inner wall of the blind hole 11. The limiting portion 111 blocks the first spring 2 in the blind hole 11. At this time, the first connecting ring 32 just fits in the connecting groove 12, and the end of the second kit 4 just abuts against the first limiting surface 13, thus completing the assembly of the spectacle hinge.

[0025] When manufacturing spectacles, prepare two sets of spectacle hinges, respectively install the tails of the two first kits 1 on the two temple arms, and respectively install the tails of the two second kits 4 at both ends of the spectacle frame. In this way, the two temple arms can be respectively installed at both ends of the spectacle frame through the two sets of spectacle hinges.

[0026] When using the glasses, since the end of the second kit 4 just abuts against the first limiting surface 13, the angle between the first kit 1 and the second kit 4 is 180 degrees, that is, the two temple arms are in an open state. The user can wear the glasses through the two temple arms, and the elastic forces of the first spring 2 and the second spring 7 can respectively press the first movable rod 3 and the second movable rod tightly in the first kit 1 and the second kit 4, making the glasses hinge in a stable state. When the user wants to fold the glasses, the user only needs to slightly forcefully bend the temple arms inward. The first movable rod 3 and the second movable rod 5 respectively compress the first spring 2 and the second spring 7, so that the second kit 4 can rotate around the first kit 1. After the end of the second kit 4 rotates 90 degrees, it just abuts against the second limiting surface 14. At this time, the angle between the first kit 1 and the second kit 4 is 90 degrees, that is, the two temple arms are in a folded state, and the elastic forces of the first spring 2 and the second spring 7 can respectively press the first movable rod 3 and the second movable rod tightly in the first kit 1 and the second kit 4, making the glasses hinge in a stable state.

[0027] The key point of the present utility model is that the present utility model has the following beneficial effects by adopting the above scheme.

[0028] 1. Utilize the elastic effects of the first spring 2 and the second spring 7 to cooperate with the opening and folding of the temple arms, and use the end of the second kit 4 to abut against the first limiting surface 13 or the second limiting surface 14 to stabilize the opening and folding states of the temple arms. The first spring 2 and the second spring 7 can also increase the elasticity of the temple arms, and the cooperation between the end face and the vertical face will not fail under the pressing force of the spring. Therefore, the glasses have the advantages of good wearing comfort and long service life.

[0029] 2. The first movable rod 3 and the second movable rod can respectively compress the first spring 2 and the second spring 7 and extend. When the first connecting ring 32 and the second connecting ring 52 are in a non-detached state, the first kit 1 can rotate 360 degrees in a plane around the end of the second kit 4, and can further compress the first spring 2 and the second spring 7 for further bending. Therefore, when the glasses are placed on a plane and accidentally stepped on, the temple arms and the frame can be bent excessively through the glasses hinge without damage, thereby effectively protecting the glasses and further extending the service life of the glasses.

[0030] A guiding groove 121 is provided on the side wall of the above-mentioned connecting groove 12, and the first connecting ring 32 is slidably fitted in the guiding groove 121. Since the component parts of the glasses hinge are all small parts, they are extremely easy to run out of position and deform during the movement process. By arranging the first connecting ring 32 in the guiding groove 121, it can play a guiding and protecting role for the first connecting ring 32 on the first movable rod 3, making the use of the glasses hinge smoother and more stable, and at the same time further extending the service life of the glasses hinge.

[0031] On the inner wall near the opening of the blind hole 11, a limiting portion 111 is provided, and the limiting portion 111 blocks the first spring 2 within the blind hole 11. In this way, when assembling the spectacle hinge, the first spring 2 can be inserted into the blind hole 11, and then stamping is performed on the outer wall of the first kit 1 near the opening of the blind hole 11 to form a limiting portion 111 on the inner wall of the blind hole 11. The limiting portion 111 blocks the first spring 2 within the blind hole 11, thus facilitating the assembly of the spectacle hinge and having the advantages of simple assembly process and low cost.

[0032] The above-mentioned first connecting ring 32 is an open ring. After passing through the second connecting ring 52, the first connecting ring 32 is bent to form a closed ring. In this way, the first connecting ring 32 and the second connecting ring 52 are connected together.

[0033] A rotating groove 131 is provided at the bottom of the above-mentioned first limiting surface 13, and a limiting rib 42 is provided at the bottom of the front end of the second kit 4. When the end of the second kit 4 abuts against the first limiting surface 13, the limiting rib 42 is fitted within the rotating groove 131. In this way, when the two temple arms are in the open state, the limiting rib 42 can be supported within the rotating groove 131 to prevent the temple arms from rotating outwards excessively, so that the two temple arms have a certain clamping force on the user, ensuring that the user can wear the glasses stably. In addition, when the temple arms are bent outwards excessively through this spectacle hinge, the limiting rib 42 and the rotating groove 131 can also act as a rotating support seat, protecting the temple arms from being easily damaged when bent outwards excessively, thereby further extending the service life of this spectacle hinge.

[0034] An arc-shaped groove 411 is provided on the inner wall of the above-mentioned through hole 41, and the second spring 7 is fitted within the arc-shaped groove 411. In this way, the arc-shaped groove 411 can limit the second spring 7, enabling the second spring 7 to work stably.

[0035] The above description of the specific exemplary embodiments of the present invention is for the purpose of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise form disclosed, and obviously, many changes and variations can be made according to the above teachings.
