Description

Technical Field

[0002] High-strength wear-resistant plastic sunglasses generally refer to sunglasses made of high-strength and high-wear-resistant plastic materials. They can withstand a certain degree of external impact without being easily damaged. The surfaces of the lenses and frames have high wear resistance and can resist friction and scratches in daily use.

[0003] At a ski resort, since the temperature of the sunglasses lenses is close to the ambient temperature and is usually at a relatively low temperature, when entering a warm rest area, the air temperature in the rest area is high, the air around the lenses heats up rapidly, the water vapor content in the air is relatively high, and a large temperature difference is formed between the lenses and the surrounding air. This temperature difference makes the temperature of the lens surface relatively low, and when the water vapor in the surrounding air encounters the colder lens surface, condensation occurs, resulting in fogging of the lenses. The fogging of the sunglasses may make it difficult to see the surrounding environment, prone to accidents such as collisions, and will cause safety hazards. Therefore, a pair of sunglasses is proposed to address the above problems. Utility Model Content

[0029] As a further implementation scheme of the above technical scheme: a cleaning plate 46 is arranged at one end of the flexible frame 43 close to the winding rope 42, the cross section of the cleaning plate 46 is arranged in a U-shape, the angle between the cleaning plate 46 and the winding rope 42 is 90°, and a pressure spring 47 and a defogger plate 48 are connected, and the elastic force of the pressure spring 47 is transmitted to the defogger plate 48, so that the defogger plate 48 can be closely attached to the surface of the lens 2, and at the same time, the U-shaped structure of the cleaning plate 46 can also play a certain protective role;

[0030] As a further implementation scheme of the above technical scheme: two sponge sheets 482 are provided, and the sponge sheets 482 are symmetrically arranged on one side of the defogger plate body 481. The sponge sheets 482 are tightly attached to one side of the lens 2 through the elastic force of the pressure spring 47. The sponge sheets 482 are parallel to each other. The sponge sheets 482 can effectively absorb water vapor on the surface of the lens 2 and prevent the lens 2 from being scratched.

[0031] As a further implementation scheme of the above technical scheme: the outer side of the rotating shaft 41 is rotatably connected to the inner side of the connecting groove 13, the fixed shaft 45 is fixedly connected to the inner side of the slide groove 12, the center points of the rotating shaft 41 and the fixed shaft 45 are located on the same horizontal line, and the rotating shaft 41 and the fixed shaft 45 are parallel to each other. By rotating the rotating shaft 41, the winding rope 42 is retracted and released, thereby controlling the movement of the flexible frame 43, and then driving the defogger plate 48 to approach or move away from the lens 2, thereby realizing the defogger function;

[0032] As a further implementation scheme of the above technical scheme: a plurality of friction holes 483 are provided, and the friction holes 483 are evenly and equidistantly distributed on one of the sponge sheets 482, and the vertical cross-section of the friction holes 483 is pentagonal in shape, and the friction holes 483 are parallel to each other, and the friction holes 483 can increase the friction with the mist and help remove tiny water droplets in the mist;

[0035] Working process: the user unfolds the high-strength wear-resistant plastic sunglasses, opens the temples 3 to a suitable angle, and wears the high-strength wear-resistant plastic sunglasses on the face. At this time, the frame body 11 is stably fixed in front of the face, and the lens 2 is located in front of the eyes to block ultraviolet rays and strong light for the eyes. When the user enters a warm room from the cold outdoors, the temperature of the lens 2 is relatively low. The warm air in the room encounters the lens 2 and causes the surface of the lens 2 to begin to fog, affecting the line of sight. At this time, the user can operate the defogger 4 and turn the shaft 41 by hand. The shaft 41 rotates in the connecting groove 13 and begins to tighten the winding rope 42 wound around the outside thereof. As the winding rope 42 is tightened, the flexible frame 43 moves along the slide groove 12 toward the shaft 41 after the reset spring 44 is stretched, and the cleaning plate 46 at one end of the flexible frame 43 also moves accordingly. The pressure spring 44 on the inner side of the cleaning plate 46 The defogger plate 48 connected to the lens 2 is also close to the lens 2. The two sponge sheets 482 on the defogger plate 48 are tightly attached to the outer side of the lens 2 under the elastic force of the pressure spring 47. The friction hole 483 on one of the sponge sheets 482 is in contact with the surface of the lens 2. The pentagonal structure of the friction hole 483 can increase the friction with the mist and help remove the tiny water droplets in the mist. The hydrophobic coating 484 on the other sponge sheet 482 can reduce the adhesion of water vapor on the surface of the lens 2 and further prevent the formation of fog. When the mist on the lens 2 is removed, the user can stop rotating the shaft 41. The flexible frame 43 and the cleaning plate 46 move along the slide groove 12 toward the fixed shaft 45 under the pulling force of the return spring 44 to clean and defog the lens 2 again. The flexible frame 43 drives the cleaning plate 46 and the defogger plate 48 away from the lens 2 and returns to the initial position, waiting to be used again when defogger is needed next time.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
