Detailed Implementation

[0015] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0016] This utility model discloses a multi-angle connection structure for eyeglass temples, including an eyeglass temple 1 and a post 2 for fixing and connecting the eyeglass frame. A horizontal groove 20 is provided at the end of the post 2, and a fixing groove 10 is provided at the end of the eyeglass temple 1. A connector 3 is provided in the fixing groove 10 and is configured to slide back and forth. A vertical groove 30 is provided at the end of the connector 3. A connector 4 is provided between the horizontal groove 20 and the vertical groove 30. The connector 4 includes a first rotating ring 40 which is horizontally disposed in the horizontal groove 20 and is configured to rotate left and right, and a second rotating ring 41 which is vertically disposed in the vertical groove 30 and is configured to rotate up and down. A connecting block 42 is provided between the first rotating ring 40 and the second rotating ring 41.

[0017] Furthermore, in order to achieve a sliding fit between the connector 3 and the fixing groove 10, a drive rod 31 is provided at the end of the connector 3 away from the vertical groove 30. A circular groove 11 for the drive rod 31 to pass through is provided at the bottom of the fixing groove 10. A fixing block 32 is provided at the end of the drive rod 31 away from the connector 3, and a sliding fit limiting ring 5 is provided at the other end. The limiting ring 5 is located at the opening of the circular groove 11. A limiting pin 6 is threaded on the side wall of the temple 1. The end of the limiting pin 6 is in contact with the outer side wall of the limiting ring 5. A spring 7 is sleeved on the drive rod 31 between the limiting ring 5 and the fixing block 32. The spring 7 is in a compressed state and abuts against the limiting ring 5 and the fixing block 32. By incorporating a spring 7 that abuts against the fixing block 32, the fixing block 32 causes the connector 3 to slide inward toward the fixing groove 10, ensuring that the temple 1 remains elastically fitted to the post 2. This provides elasticity when the temple 1 folds left, right, up, or down, and allows for quick resetting when subjected to external force. Furthermore, a limiting pin 6 secures the limiting ring 5 to the opening of the circular groove 11. If the spring 7 is damaged during prolonged use, the limiting pin 6 can be unscrewed, allowing the connector 3 and drive rod 31 to be removed, and the spring 7 replaced or repaired – a very convenient operation.

[0018] Furthermore, in order to ensure that the limiting pin 6 can stably fix the limiting ring 5 in the fixing groove 10, an annular groove 50 is provided on the circumference of the limiting ring 5, and the end of the limiting pin 6 is adapted to be engaged in the annular groove 50.

[0019] Furthermore, in order to achieve stable installation of the first rotating ring 40 and the second rotating ring 41, a fixing screw 8 is provided in the transverse groove 20 to be rotatably connected to the first rotating ring 40. The fixing screw 8 is threadedly connected to the pile head 2 for fixation. A rotating shaft 9 is provided in the vertical groove 30 to be rotatably connected to the second rotating ring 41.

[0020] Furthermore, in order to ensure smooth folding and rotation of the temple 1, guide blocks 21 are provided on the upper and lower sides of the end of the head 2 relative to the transverse groove 20, and the end of the guide block 21 near the inner side of the temple 1 is provided with an arc-shaped edge.

[0021] Furthermore, in order to ensure smooth rotation and folding of the temple 1, the end of the connector 3 is rounded.

[0022] Working principle: When the temple 1 needs to be opened or folded by rotating left or right, the connector 3 at the end of the temple 1 will drive the connector 4 to rotate left or right. When the connector 4 is driven by the left or right rotation, the first connecting ring will rotate left or right within the horizontal groove 20 of the head 2 to open or fold the temple 1. When the temple 1 is rotated up or down by an external force, the connector 3 at the end of the temple 1 will drive the connector 4 to rotate up or down. When the connector 4 is driven by the up or down rotation, the second connecting ring will rotate up or down within the vertical groove 30 of the connector 3 to fold the temple 1 up or down. In this way, the temple 1, through the connector 4, can fold left, right, up, and down around the head 2, thereby opening and storing the temple 1. It can also fold when the temple 1 is subjected to outward, upward, and downward pressure, preventing the connection between the temple 1 and the frame from breaking under stress and causing damage to the glasses.

[0023] The temple 1 of this practical eyeglasses can be folded in all directions, so it has good resistance to bending and torsion and a long service life. In addition, the spring 7 inside the temple 1 can be easily disassembled, replaced or repaired, making it very convenient to operate and worthy of widespread promotion.
