Description

Double-layer sunglasses with lens slots

Technical Field

The utility model relates to the technical field of sunglasses, in particular to a double-layer sunglasses with lens slots.

Background Art

Sunglasses are a kind of vision care product, which are mainly used to prevent damage to human eyes caused by strong stimulation of sunlight. The lenses of sunglasses are usually dark in color, which can block ultraviolet rays and part of visible light, thereby reducing irritation and damage to the eyes. There are many types of sunglasses on the market, which can be roughly divided into shallow sun-shading glasses and deep sun-shading glasses according to the required degree of shading. The lens color depths of shallow sun-shading glasses and deep sun-shading glasses are different.

Sunglasses on the market are generally used with two lenses of the same color. Only one lens can be installed on one side of the frame. There are no two lens slots for assembling two lenses. When the user is myopic, if he wants to wear sunglasses, he cannot directly insert the myopic lens and the sunshade lens into the frame at the same time. If the myopic glasses and sunglasses are worn on the eyes at the same time, the two glasses brackets will increase the weight of the ears and the bridge of the nose, making it uncomfortable to wear. In view of this, we propose double-layer sunglasses with lens slots.

Specifically, an intermediate beam 14 is arranged between the two mirror frames 1, and a limiting cylinder 15 is fixedly installed inside the intermediate beam 14. A plurality of first V-shaped grooves 151 and a plurality of second V-shaped grooves 152 arranged in a ring shape and at equal intervals are arranged on the inner wall of the limiting cylinder 15. Each second V-shaped groove 152 is located between two adjacent first V-shaped grooves 151. A clamping assembly 2 is arranged on the intermediate beam 14. The clamping assembly 2 includes two clamping plates 20 which are symmetrical to each other and pressed on the top surface of the mirror frame 1. A center plate 21 is fixedly installed between the two clamping plates 20. A boss 22 is rotatably connected to the center plate 21. A push button 24 is rotatably connected to the top of the boss 22. A limiting block 23 is fixedly installed on the bottom end column of the boss 22. The limiting block 23 is engaged with the corresponding first V-shaped groove 151 and second V-shaped groove 152. The depth of the first V-shaped groove 151 is greater than the depth of the second V-shaped groove 152. The bottom end of the boss 22 A spring 25 is arranged between the stopper 15 and the boss 22. The boss 22 and the stopper 15 are connected by a smooth thread. The bottom end of the spring 25 is fixedly mounted on the bottom wall of the stopper 15. The top end of the spring 25 abuts against the bottom surface of the boss 22. When the stopper 23 slides into the first V-shaped groove 151 and the stopper 23 abuts against the top wall of the first V-shaped groove 151 under the elastic force of the spring 25, the push button 24 no longer presses the center plate 21. The center plate 21 can be rotated to rotate the clamping plate 20 to one side to carry out the loading and unloading operations of the lens 13. After the clamping plate 20 is straightened, the limit block 23 is inserted into the second V-shaped groove 152 and rests on the top wall of the second V-shaped groove 152. At this time, the pressing button 24 is pressed down to press the center plate 21, and further drives the clamping plate 20 to be pressed on the frame 1, so as to block the end of the lens slot 12 and prevent the lens 13 from falling out.

In this embodiment, the bottoms of the first V-shaped groove 151 and the adjacent second V-shaped groove 152 are connected to each other, so that the limiting block 23 can be switched between the first V-shaped groove 151 and the second V-shaped groove 152 .

Specifically, a through hole 211 is provided on the center plate 21, and the boss 22 passes through the through hole 211 and is rotatably connected with the through hole 211. The outer diameter of the push button 24 is larger than the outer diameter of the through hole 211, so that the center plate 21 will not block the normal rotation of the boss 22.

Furthermore, a rubber pad 201 is fixedly mounted on the bottom surface of the pressing plate 20 , and the rubber pad 201 is used for buffering and protecting operations.

When the double-layer sunglasses with lens slots of the utility model are in use, since the rubber pad 201 is elastic, within the elastic range of the rubber pad 201, the push button 24 is pressed, and as the push button 24 is pressed down, the boss 22 is driven to move downward, and the downward movement of the boss 22 drives the limit block 23 to slide from the top of the second V-shaped groove 152 to the bottom of the second V-shaped groove 152. At this time, as the boss 22 continues to be pressed down, the smooth thread on the boss 22 is threadedly connected with the smooth thread on the inner wall of the limit tube 15. At this time, the boss 22 can rotate. After the boss 22 rotates, it drives the limit block 23 to rotate from the bottom position of the second V-shaped groove 152 to the first V-shaped groove 151. At this time, the push button 24 is released, and the elastic force of the spring 25 drives the boss 22 to move upward, and further drives the limit block 23 to move upward and get stuck on the top wall of the first V-shaped groove 151. Since the depth of the first V-shaped groove 151 is greater than the depth of the second V-shaped groove 152, at this time, when the limit block 23 abuts against the top wall of the first V-shaped groove 151, the distance between the push button 24 and the middle beam 14 increases, and the push button 24 no longer presses the center plate 21. At this time, the center plate 21 is rotated until the pressing plate 20 no longer blocks the notch of the lens slot 12, and the notch of the lens slot 12 is exposed to the outside, so that the loading and unloading operations of the lens 13 can be carried out normally.

After loading and unloading are completed, the clamping plate 20 is straightened to a position directly above the lens slot 12, and the push-down button 24 is continued to be pressed, which can drive the limit block 23 to slide downward along the first V-shaped groove 151. After sliding to the bottom position of the first V-shaped groove 151, the boss 22 is driven to rotate with the smooth threaded connection to drive the limit block 23 to move to the second V-shaped groove 152. At this time, the push-down button 24 is released, and the spring 25 can drive the limit block 23 to be stuck on the top wall of the second V-shaped groove 152. At this time, the distance between the push-down button 24 and the middle beam 14 is reduced. With the use of the rubber pad 201, the push-down button 24 can be used to clamp the center plate 21, and further the clamping plate 20 can be clamped to prevent the lens 13 from falling out, which is convenient for use.
