Description

Technical Field

[0001] The utility model relates to the technical field of protective glasses, in particular to a pair of protective glasses. Background Art

[0002] Protective glasses are a special type of glasses that can prevent damage from radioactivity, chemical, mechanical and light of different wavelengths. Depending on the application scenario, common protective glasses include dust-proof glasses, impact-proof glasses, chemical-proof glasses and light-radiation-proof glasses, etc. Currently, medical staff who need to come into contact with radioactive substances or are exposed to radiation in the working environment need to wear protective glasses at work to reduce radiation damage to the eyes.

[0003] Existing protective glasses usually have a sponge layer at the nose bridge groove to adapt to different nose bridge heights and thus to different users;

[0004] For example, Chinese patent publication number CN218607041 U discloses "a kind of protective glasses", which uses an elastic band, a hanging hole and an extended hanging strap, in conjunction with a nose pad, a socket and a hanging slot, so that the elastic band can be unfolded in accordance with the shape of the nose bridge slot, and is buckled and fixed with the hanging holes on both sides and the hanging slots at the corresponding positions. After the extended hanging strap is connected to the socket, it can limit the elastic band and the sponge layer as a whole to avoid forward and backward deviation during use. The elastic band and the sponge layer inside it are an integrally detachable structure, and the sponge can be replaced in time after being soaked by the sweat on the face of the medical staff; but in actual use, when the elastic band is connected to the hanging slot, the hanging hole and the socket, the elastic band is subjected to greater force and is prone to breakage and separation from the sponge layer, causing the sponge layer to fall off easily, affecting the user experience.
