Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a connection structure between a spectacle frame and temple arms. Background Art

[0002] Chinese Patent No. CN217521446U discloses a connection structure between a spectacle frame and temple arms and glasses, including a first connecting member installed on the spectacle frame and a second connecting member installed on the temple arms. One end of the first connecting member close to the second connecting member is provided with a rotation groove, and one end of the second connecting member close to the first connecting member is provided with a rotation ring. The rotation ring is rotatably connected in the rotation groove. An installation hole is opened on the groove side wall of the rotation groove, and a limiting head and an elastic member are arranged in the installation hole. The elastic member drives the limiting head to move towards the rotation ring side. An arc-shaped first limiting groove and a second limiting groove are opened on the circumferential side of the rotation ring, and a limiting portion is arranged on the second connecting member.

[0003] When the above glasses are worn, if an external force is applied to the temple arms during wearing, the limiting head is likely to slide out of the second limiting groove and enter between the second limiting groove and the limiting portion. After the limiting head slides out of the second limiting groove, there is no second limiting groove to limit the limiting head, and the first connecting member and the second connecting member are likely to rotate relative to each other due to the external force, which will cause the two temple arms to turn outwards and move away from each other when the glasses are worn, so that the two temple arms cannot effectively clamp the head of the glasses wearer, resulting in the glasses being likely to fall off when worn. Summary of the Utility Model

[0004] The present application provides a connection structure between a spectacle frame and temple arms. By setting a limiting block to prevent the limiting head from sliding out of the second chute, and cooperating with a spring, the turned-out temple arms can be moved back to their original positions to re-clamp the head of the glasses wearer.

[0005] The connection structure between a spectacle frame and temple arms provided by the present application adopts the following technical solution:

[0006] A connection structure between a spectacle frame and temple arms, including a first connecting member for connecting with the temple arms, a second connecting member for connecting with the spectacle frame, a rotation groove opened at one end of the connecting member, a rotation ring arranged on the second connecting member, an installation hole opened on the groove wall of the rotation groove, a limiting head slidably connected in the installation hole, and a spring arranged in the installation hole. The spring is always in a compressed state and presses the limiting head against the rotation ring. The rotation ring is provided with an arc-shaped first limiting groove and an arc-shaped second limiting groove. The rotation ring is also provided with a limiting block. The limiting block is located on the side of the second limiting groove away from the first limiting groove. The limiting block is used to prevent the limiting head from moving to the side of the second limiting groove away from the first limiting groove.

[0007] By adopting the above technical solution, when the temple of the glasses is opened, the limit head is located in the second limit groove, and when the temple of the glasses is folded, the limit head is located in the first limit groove. When the glasses are worn, the limit head is located in the second limit groove. If an external force acts on the temple or the frame, the connecting member I installed on the frame and the connecting member II installed on the temple will rotate relative to each other, causing the rotating ring to rotate relative to the limit head. When the rotating ring rotates and the limit head rotates relative to each other, the groove wall of the second limit groove will squeeze the limit head. At this time, the limit head will move retractively into the mounting hole and compress the spring, and at the same time, the limit head will gradually move out of the second limit groove. When the limit head is about to move out of the second limit groove, the limit block will collide with the limit head, and the limit block will press the limit head against the side wall of the mounting hole, thereby preventing the limit head from further moving into the mounting hole, thus preventing the limit head from moving out of the second limit groove. Then the spring will rebound to drive the limit head to move away from the mounting hole and return to its original position. Under the action of the limit head, the connecting member I and the connecting member II will rotate back, causing the temple to reset and clamp the wearer's head again. Therefore, by setting the limit block to block the limit head from sliding out of the second chute and cooperating with the spring, the outward-turned temple can move back to its original position and clamp the wearer's head again.

[0008] Preferably, an arc-shaped groove is formed on the surface of the limit block away from the rotating ring, and the arc-shaped groove fits with the spherical inclined surface of the limit block when the limit block presses the limit head against the side wall of the mounting hole.

[0009] By adopting the above technical solution, the pressing and limiting effect of the limit block on the limit head is better when the limit block collides with the limit head.

[0010] Preferably, an installation post is provided at one end of the connecting member I, the rotating groove is formed on the installation post, a first threaded hole is formed in the installation post, the first threaded hole communicates with the rotating groove, a bolt is provided in the first threaded hole, and the rotating ring is hinged on the bolt.

[0011] By adopting the above technical solution, setting the bolt as the connecting member between the connecting member I and the connecting member II makes the product assembly more convenient. Compared with the traditional pin as the connecting member, the bolt is less likely to fall off from the connection, so the connection stability between the connecting member I and the connecting member II is better.

[0012] Preferably, the first threaded hole is a countersunk hole, and the bolt is completely located in the first threaded hole.

[0013] By adopting the above technical solution, it is prevented that the head of the bolt scratches the wearer of the glasses during the use of the glasses.

[0014] Preferably, reinforcing blocks are provided on both the upper surface and the lower surface of the connecting member I, and both of the two reinforcing blocks are connected to the installation post.

[0015] By adopting the above technical solution, a reinforcing block is provided to enhance the connection strength between the first connecting piece and the mounting post, so as to make up for the defect of the reduced connection strength between the mounting post and the first connection caused by the opening of the rotating groove. At the same time, the two reinforcing blocks will cooperate with the grooves on the temple when the first connecting piece is inserted into the temple, achieving a guiding effect, making it easier for the first connecting piece to be inserted into the assembly groove of the temple.

[0016] Preferably, a limiting block is provided on the rotating ring, the limiting block is located between the first limiting groove and the second limiting groove, and both ends of the limiting block are respectively connected to the groove wall of the first limiting groove and the groove wall of the second limiting groove.

[0017] By adopting the above technical solution, the limiting block is provided, so that when the limiting head is located in the first limiting groove or the second limiting groove, it is not easy to move out of the two limiting grooves, thus ensuring the stability of the use state of the glasses.

[0018] Preferably, a second threaded hole is opened on the side wall of the first connecting piece, and the second threaded hole is used to cooperate with the screw installed on the temple.

[0019] By adopting the above technical solution, opening the second threaded hole facilitates the connection between the first connection and the temple.

[0020] The technical effects of the present utility model are mainly reflected in the following aspects:

[0021] 1. The present utility model blocks the limiting head from sliding out of the second sliding groove by setting a limiting block, and at the same time, in cooperation with the spring, it can make the everted temple move back to its position to re-clamp the head of the glasses wearer;

[0022] 2. The present utility model sets a bolt as the connecting piece between the first connecting piece and the second connecting piece, making the product more convenient to assemble. Compared with the traditional plug pin as the connecting piece, the bolt is less likely to fall off from the connection, so the connection stability between the first connecting piece and the second connecting piece is better;

[0023] 3. The present utility model sets two reinforcing blocks on the first connecting piece to enhance the connection strength between the first connecting piece and the mounting post, so as to make up for the defect of the reduced connection strength between the mounting post and the first connection caused by the opening of the rotating groove.

Specific embodiments

[0030] The following further describes the present application in detail with reference to the accompanying drawings, so that the technical solutions of the present application are easier to understand and master.

[0031] Referring to Figures 1-3 , a connecting structure between a spectacle frame and temple arms of this embodiment includes a first connecting member 1 for connecting with the temple arms, a second connecting member 2 for connecting with the spectacle frame, a mounting post 3 fixed on the first connecting member 1, and a rotating ring 4 fixed on the second connecting member 2. A first threaded hole 32 and a rotating groove 31 are provided on the mounting post 3. The first threaded hole 32 is a countersunk hole, the first threaded hole 32 communicates with the rotating groove 31, a screw is threadedly connected in the first threaded hole 32, and the screw is completely located in the first threaded hole 32. The rotating ring 4 extends into the rotating groove 31 and is hinged to the screw.

[0032] Referring to Figures 1-3 , on one surface of the first connecting member 1 communicating with the rotating groove 31, a mounting hole 11 is provided along a direction perpendicular to the axis of the first threaded hole 32. A second threaded hole 8 is provided on the side wall of the first connecting member 1 away from the second connecting member 2, and the second threaded hole 8 is used to cooperate with the screw mounted on the temple arms.

[0033] Referring to Figures 1-3 , a spring 13 is placed in the mounting hole 11 and a limit head 12 is slidably connected along the axis of the mounting hole 11. The limit head 12 is a spherical member. One end of the spring 13 abuts against the bottom wall of the mounting hole 11, and the other end of the spring 13 abuts against one end of the limiting block 5 away from the rotating ring 4. The spring 13 is always in a compressed state and presses the limit head 12 against the rotating ring 4.

[0034] Referring to Figures 1-4, the rotating ring 4 is provided with an arc-shaped first limiting groove 41 and an arc-shaped second limiting groove 42. When the temple of the glasses is opened, the limiting head 12 is located in the second limiting groove 42. When the temple of the glasses is folded, the limiting head 12 is located in the first limiting groove 41. A limiting block 43 is also fixedly connected to the rotating ring 4. The limiting block 43 is located between the first limiting groove 41 and the second limiting groove 42. The two ends of the limiting block 43 are respectively connected to the groove wall of the first limiting groove 41 and the groove wall of the second limiting groove 42.

[0035] Refer to Figures 1-5 , a limiting block 5 is also fixed on the rotating ring 4. The limiting block 5 is located on the side of the second limiting groove 42 away from the first limiting groove 41. The limiting block 5 is used to block the movement of the limiting head 12 to the side of the second limiting groove 42 away from the first limiting groove 41. When the glasses are worn, the limiting head 12 is located in the second limiting groove 42. If an external force acts on the temple or the frame, the connecting member one 1 installed on the frame and the connecting member two 2 installed on the temple will rotate relative to each other under the action of the force, so that the rotating ring 4 rotates relative to the limiting head 12. When the rotating ring 4 rotates and the limiting head 12 rotates relative to each other, the groove wall of the second limiting groove 42 will squeeze the limiting head 12. At this time, the limiting head 12 will move back into the mounting hole 11 and compress the spring 13. At the same time, the limiting head 12 will gradually move out of the second limiting groove 42. When the limiting head 12 is about to move out of the second limiting groove 42, the limiting block 5 will collide with the limiting head 12, and the limiting block 5 will press the limiting head 12 against the side wall of the mounting hole 11, thereby preventing the limiting head 12 from further moving into the mounting hole 11 and preventing the limiting head 12 from moving out of the second limiting groove 42.

[0036] Refer to Figures 1-5 , then after the external force disappears, the spring 13 will rebound to drive the limiting head 12 to move away from the mounting hole 11 and reset. Under the action of the limiting head 12, the connecting member one 1 and the connecting member two 2 will rotate back, so that the temple resets to clamp the head of the glasses wearer again. Therefore, by setting the limiting block 5 to block the limiting head 12 from sliding out of the second chute, and cooperating with the spring 13, the outward-turning temple can be moved back to clamp the head of the glasses wearer again.

[0037] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
