Description

Technical Field

[0001] The utility model relates to the technical field of eyeglass accessories, in particular to a memory combined hinge structure for eyeglass frames. Background Art

[0002] The hinges of ordinary TR eyeglass frames can usually only be pulled outwards during use, and are often easily damaged during rough use by children (such as violent up and down stretching, violent twisting and stretching).

[0003] In order to improve the connection strength between the eyeglass frames and the temples, most eyeglass frames on the market currently use stainless steel connecting blocks in combination with flexible memory metal temples. The stainless steel connecting blocks and the eyeglass frames are fixed with screws, and then the flexible memory metal temples are welded to the connecting blocks to ensure the connection strength. However, the high temperature or stress generated by the flexible memory metal during welding will destroy the metal memory and cause the recovery characteristics of the temples to be destroyed. If screws are used for connection, on the one hand, the temples will be very bloated and unsightly, and on the other hand, the screws will easily loosen, resulting in the temples being unable to return to their original positions after long-term use, resulting in deformation of the glasses, loose wearing and other usage problems, which greatly affects the user experience.

[0004] Based on this, the utility model designs a memory combination hinge structure for a glasses frame to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a memory combination hinge structure for eyeglass frames. The utility model improves and strengthens the internal structure of the hinge to resist external forces and achieve the effects of torsion resistance, tension resistance, compression resistance, non-deformation and wear resistance to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A memory combination hinge structure for a glasses frame comprises a glasses frame, a memory core rod is connected to the glasses frame, an injection molding groove is opened on the upper side of the glasses frame, a hard inner core for connecting the memory core rod is fixedly connected to the inner thread of the injection molding groove, an injection molding shell is integrally injection molded on the outside of the hard inner core, one end of the injection molding shell is connected to the injection molding groove, the memory core rod passes through the other end of the injection molding shell and is connected to the hard inner core, the hard inner core and the memory core rod are press-fitted and connected via a pressure positioning joint point, and the pressure positioning joint point is located inside the injection molding shell.

[0008] Preferably, the hard inner core includes an inner core plug for being placed in the injection molding groove, an inner core jack for inserting the end of the memory core rod is opened on the right side of the hard inner core, a press-fit opening communicated with the inner core jack is opened on the top of the hard inner core, an inner core pressure block integrated with the hard inner core is arranged in the press-fit opening, a memory groove is opened on the end of the memory core rod for inserting into the inner core jack, the position of the memory groove is opposite to the press-fit opening, and the inner core pressure block is filled into the memory groove after being pressed down by the external pressure mold.

[0009] Preferably, one end of the injection-molded shell is fitted with the inner core plug to form a shell slot head that wraps the inner core plug, and the other end of the injection-molded shell is formed with a rod socket for inserting the memory spleen core rod.

[0010] Preferably, a frame screw hole for fastening is provided through the injection molding groove, and openings are provided on the shell slot head and the inner core plug to match the frame screw hole.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model does not use welding and high temperature bonding, so as not to destroy the memory property of the device. Instead, it adopts a pressure positioning bonding method, that is, the material on the hard inner core is partially filled into the memory spleen core rod through external force, so that the hard inner core and the memory spleen core rod are connected as a whole, and the memory spleen core rod can also remain stable and will not rotate. During use, even if the memory spleen core rod is subjected to violent force, the injection molded shell wraps the connection point between the hard inner core and the memory spleen core rod, and the injection molded shell will also release part of the force, thereby improving the stability of the connection between the hard inner core and the memory spleen core rod, and preventing the connection between the hard inner core and the memory spleen core rod from loosening, thereby ensuring stable recovery without deformation.

[0016] 2. The injection molded shell provided in the utility model increases the friction force connected with the injection molded groove, preventing the hard inner core from being directly connected with the injection molded groove and possibly loosening due to long-term use, in order to keep the memory spleen core rod in the best recovery state.
