[0016] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0017] This utility model discloses an eyeglass with adjustable temple tension, including a frame 1, temples 2 at both ends of the frame 1, and lenses 3 embedded in the frame 1. The temples 2 are fixedly connected to the frame 1 by an adjustment device 4. The adjustment device 4 includes a connector 40, a lever 41, and a spring 42. One end of the connector 40 is fixedly connected to the frame 1, and the other end is provided with a connecting piece 400. A limiting groove 401 inclined towards the inside of the frame 1 is provided at the front of the connecting piece 400. A connecting groove 20 adapted to the connecting piece 400 is provided at the end of the temple 2 near the frame 1. A vertically arranged connecting groove 20 is provided in the connecting groove 20 to the connecting piece 400. A rotating shaft 5 is rotatably engaged. A circular groove 21 is provided at the bottom of the connecting groove 20. The lever 41 is slidably placed in the circular groove 21. The front end of the lever 41 can slide out of the circular groove 21 and form a locking engagement with the limiting groove 401 on the connecting piece 400. The spring 42 is provided between the lever 41 and the bottom wall of the circular groove 21. A push rod 410 extending out of the temple 2 is provided on the lever 41. An L-shaped sliding groove 22 communicating with the circular groove 21 is provided on the temple 2. One end of the L-shaped sliding groove 22 is vertically arranged along the length of the temple 2. The push rod 410 can slide back and forth along the L-shaped sliding groove 22.

[0018] Furthermore, one end of the L-shaped slide groove 22, which is arranged laterally, is provided with an embedding groove 220 for the push rod 410 to be embedded. By providing the embedding groove 220, the push rod 410 can be stably locked in the embedding groove 220, and it is not easy for it to slide easily in the L-shaped slide groove 22, making the structure more stable.

[0019] Furthermore, the lever 41 includes a slide rod 411 that slides in conjunction with the circular groove 21. The push rod 410 is disposed on the body of the slide rod 411. A top head 412 that engages with the limiting groove 401 is disposed at the front end of the slide rod 411. A connecting rod 413 with a diameter smaller than the body of the slide rod 411 is disposed at the rear end of the slide rod 411. One end of the spring 42 is sleeved on the connecting rod 413, and the other end is engaged with the bottom wall of the circular groove 21.

[0020] Furthermore, the limiting groove 401 is V-shaped, and the two sides of the opening of the limiting groove 401 are arc-shaped. By making the two sides of the opening of the limiting groove 401 arc-shaped, the top head 412 can be more easily aligned with the limiting groove 401 for insertion.

[0021] Furthermore, the end of the push rod 410 is provided with a toggle head 414 with a diameter larger than that of the push rod 410 body.

[0022] Working principle: When people use the glasses and the temples 2 deform or need to be clamped, the actuating head 414 is pushed laterally, causing the actuating head 414 to drive the pushing rod 410 to slide along one end of the L-shaped groove 22. During the sliding of the pushing rod 410, the lever 41 rotates within the circular groove 21. When the pushing rod 410 slides to the vertical end of the L-shaped groove 22, the force applied to the actuating head 414 stops. At this time, the lever 41 loses the resistance between the pushing rod 410 and the L-shaped groove 22, and thus slides towards the connecting groove 20 within the circular groove 21 under the elastic force of the spring 42. When the top head 412 at the front end of the lever 41 slides into the limiting groove 401 on the connecting piece 400, the top head 412 forms a limiting engagement with the limiting groove 401. Figure 2 As shown, since the limiting groove 401 at the front of the connecting piece 400 is inclined towards the inside of the frame 1, the lever 41 will drive the temple 2 to form a certain angle with the connecting piece 400, so that the two temples 2 will be tightened towards the inside of the frame 1 and firmly clamped to the head, which can greatly improve the stability when people wear them. The whole operation process is simple and convenient.

[0023] When the temple 2 is not clamped, the actuating head 414 can be pushed toward the end of the temple 2, causing the actuating head 414 to move the lever 41 and the push rod 410 away from the connecting piece 400. This causes the top head 412 to lose its limiting position on the connecting piece 400. Finally, the actuating head 414 is pushed into the horizontally positioned end of the L-shaped slide groove 22, so that the actuating head 414 is locked in place by the squeezing force of the spring 42, thereby restoring the temple 2 to its original tightness for wearing.

[0024] This practical pair of glasses can quickly tighten the two temples 2 inward through the adjustment device 4, thereby improving the stability when people wear them.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
