Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a slingshot and glasses without screws or welding. Background Art

[0002] Glasses are generally tools for vision correction and eye protection. Some are also used as accessories to add personal style and fashion sense. Generally, glasses are mainly composed of lenses, frames, nose pads and temples. Temples are a very important part of the frame of glasses. They are used to support glasses and hang behind the ears. The structure of temples directly affects whether the human body is comfortable to wear. On the market, there are many materials and structures of temples, among which the main materials are copper or stainless steel. Generally, temples include a head and temples. The head and temples are connected by hinges, which can make the temples closed when not in use, saving space and having certain flexibility. Hinges are generally divided into front hinges and rear hinges. The front hinge is welded to the head, and the rear hinge is welded to the temple. The temples are opened and closed by hinges. In order to make glasses adapt to users with different head shapes, a spring hinge structure has emerged. This hinge design adopts a spring mechanism and has a certain elasticity. A spring is provided in the slingshot hinge, so that the opening angle can be adjusted according to the size of the wearer's head by stretching the spring. However, the spring hinge structure is very complicated and not easy to repair. At the same time, it needs to be welded to the head and glasses, and cannot be used for some materials that are not easy to weld. Glasses are generally produced by welding or screwing, which can easily cause problems such as desoldering or screw stripping, and the production process is complicated.

[0003] In recent years, in the field of glasses, glasses frames made of titanium alloy are light, strong, durable, comfortable, and fashionable, and are favored by the general public. However, due to the particularity of the material, its design structure is subject to many restrictions. Utility Model Content
