Problems solved by technology
[0002] When people wearing myopia glasses swim in lakes, rivers and seas, they often encounter an embarrassing problem, which is the trouble of finding the external glasses after they fall into the water. Connect an elastic band around the surface of the back of the head to prevent the glasses from falling off under the impact of sports or waves. The glasses that automatically tighten the temples to prevent the glasses from falling off when swimming after entering the water will improve the convenience of users and will be welcomed by consumers

Embodiment Construction
[0008] From figure 1 It is known that a kind of anti-drop glasses that automatically shrink when exposed to water is composed of a frame 1, a lens 2, and temples 3. The rear and tail ends of the temples are provided with a bow-shaped convex part 4 and a positioning hole. 6. The two ends of the agave elastic band 5 are provided with positioning pins and are integrated with the positioning holes 6 at both ends of the bow-shaped raised part 4 at the rear of the temple and the tail end.
[0009] The mirror frame 1 and mirror legs 3 are made of TR90 memory plastic or metal materials. In order to prevent the plastic mirror legs from bending outward under the tension of the telescopic sliding arm plate, the mirror legs 3 are pre-bent and shaped at an angle of 15-30°.

The invention discloses a pair of anti-dropping glasses capable of being automatically shrunk in water. The glasses consist of a glass frame, lenses and glass legs. The glasses are characterized in that arched convex parts and positioning holes are formed in the rear parts and the tail ends of the glass legs; positioning pins are arranged at two ends of maguey elastic bands; the positioning pins are also integrally connected with the positioning holes in two ends of the arched convex parts at the rear parts and the tail ends of the glass legs. When people wear the glasses and swim in water, glass leg sleeves of the people are wetted by water and rapidly expand to convex up, then the size is increased by 2-3 times, and a security guarantee function that the glasses are prevented from sliding and falling into water under the external force of water wave impact is achieved.
Description
technical field [0001] The invention relates to the technical field of application of special glasses, in particular to anti-drop glasses that automatically tighten when exposed to water and a manufacturing method thereof. Background technique [0002] When people wearing myopia glasses swim in lakes, rivers and seas, they often encounter an embarrassing problem, which is the trouble of finding the external glasses after they fall into the water. Connect an elastic band around the surface of the back of the head to prevent the glasses from falling off under the impact of sports or waves. The glasses that automatically tighten the temples to prevent falling off when swimming after entering the water will improve the convenience of users and will be welcomed by consumers. Contents of the invention [0003] The invention provides an anti-shedding glasses that automatically tighten when exposed to water. Using the property of agave fibers that strongly shrink when exposed to ...
