Background
The traditional hinge mechanism comprises a glasses leg, a glasses frame, a glasses beam, a nose support, a lens and the like, wherein the glasses leg is connected to the glasses frame through the hinge mechanism with a screw as a hinge shaft, and in order to enable the glasses leg to have a certain range of elastic return function in the opening or closing process, the hinge mechanism of the existing glasses adopts a slingshot hinge mechanism component with a mandril (or a pull rod) and a spring. In the past, the materials of the spectacle frame, except for the metal materials, are mostly produced by using polymer resin materials (such as acetate fibers). In order to install the components of the catapult hinge mechanism, the prior method is to fixedly weld the components of the catapult hinge mechanism at the front end of the metal temple, and then insert the temple into the glasses leg from the front end of the glasses leg (namely, the mode of inserting the pin), but the mode can only be suitable for the glasses leg produced by taking acetate fiber plates as raw materials, along with the development of material technology, the glasses leg produced by taking TR-90 (plastic titanium) as the raw material is increasingly adopted at present, the TR-90 (plastic titanium) is a high polymer material with memorability, is the current international most popular ultra-light glasses frame material, has the characteristics of super toughness, impact resistance, wear resistance, low friction coefficient and the like, can effectively prevent the damage to eyes and face caused by the fracture and friction of the glasses frame in motion, has the specific molecular structure and good chemical resistance, is not easy to deform under the high-temperature environment, and can resist the high temperature of 350 ℃ in a short time, is not easy to melt and burn. When the glasses legs are produced by using materials such as TR-90 (plastic titanium) and the like as raw materials, the process requirement is that an injection molding mode is adopted, and the slingshot hinge mechanism component is installed after injection molding.
