Description
Technical Field
The utility model relates to the technical field of glasses, in particular to a magnet glasses frame
Background
With the improvement of the living standard of people, glasses become a living mode of many people. Glasses have been more than just in terms of their functional protection against radiation, vision correction, etc. More people are beginning to put new demands on the decorative function of the glasses when they are worn. Based on this, some glasses with replaceable glasses frames are also coming out on the market. Typically, such eyeglasses include a main frame and a front frame. The main frame is similar to a conventional spectacle frame. Most eyeglass frames consist of brow frames, eyeglass legs, connecting pieces (such as hinges) and the like; the lens is fixed in the picture frame, and the picture frame is located the eyebrow frame below, and the nose holds in the palm and installs in the picture frame inboard, and the mirror leg passes through connecting piece and eyebrow frame swing joint. The front frame is detachably connected to the main frame in a certain mode. By rapid replacement of the front frame, a variety of eyeglass frames, including patterns, colors, and the like, can be achieved. Therefore, such glasses are also required to have a relatively high aesthetic degree. However, in order to realize quick replacement of the front frame, the conventional spectacle frame mostly uses a magnet adsorption manner to realize connection between the front frame and the main frame. In the production of such magnet eyeglass frames, the prior art generally utilizes injection molding of an eyeglass frame having magnet mounting holes. The magnet assembly hole has a one-way opening through which a magnet can be manually inserted into the magnet assembly hole. Finally, the opening is polished by sealing or other means to provide a degree of uniformity between the opening and the frame body.
However, this prior art approach requires manual secondary grinding after the magnets are later inserted to ensure a good transition and uniformity between the opening and the frame. In addition, since the eyeglass frame is provided with an obvious opening, even though the eyeglass frame is manually polished in a later period, the unevenness caused by chromatic aberration, materials and the like between the eyeglass frame and the opening cannot be reduced. The abrupt assembly marks left by the magnets on the front frame and the main frame seriously damage the integrity of the glasses, and reduce the original purpose of the replaceable glasses for pursuing beauty.

The third injection-molded layer 21 and the fourth injection-molded layer 22 do not need to be combined by other connection modes.
Based on the combination of the third injection-molded layer 21 and the fourth injection-molded layer 22, the third injection-molded layer 21 has a surface close to the fourth injection-molded layer 22 and a surface distant from the fourth injection-molded layer 22. In the present embodiment, the surface of the third injection layer 21 having the surface close to the fourth injection layer 22 is defined as a second surface 211. It will be appreciated that the bi-color injection molding machine continues to injection mold the fourth injection molded layer 22 onto the second surface 211 of the third injection molded layer 21 after injection and completion of the injection molding of the third injection molded layer 21.
In this embodiment, a second magnet anchor point 212 is disposed on the second surface 211. The second magnet 4 is placed on the second magnet positioning point 212. The fourth injection molding layer 22 covers the second surface 211 and the second magnet 4 disposed on the second surface 211, so that the second magnet 4 is sealed between the third injection molding layer 21 and the fourth injection molding layer 22. The sealing here means that the third injection-molded layer 21 and the fourth injection-molded layer 22 form a closed space, and the second magnet 4 is sealed between the third injection-molded layer 21 and the fourth injection-molded layer 22. It should be noted that the third injection layer 21 and the fourth injection layer 22 are each injection molded once and the injection molding time intervals of the two are close enough to enable the two to be closely bonded together. The third injection layer 21 and the fourth injection layer 22 formed by one injection molding have complete surfaces. No additional openings are required to accommodate the second magnets 4.
It should be appreciated that in the present embodiment, the first magnet anchor point 112 and the second magnet anchor point 212 may have a plurality to increase the number of the first magnet 3 and the second magnet 4 that can be placed. By increasing the number of magnets, the connection strength and stability between the front frame and the main frame can be enhanced. In some embodiments, the first magnet 3 and the second magnet 4 are N52 ru-fe-b magnets.
In some embodiments, the first magnet anchor 112 may be a cavity with a single opening formed in the first surface 111. The first magnet 3 is placed in the cavity and forms a tight fit with the cavity. Likewise, the second magnet anchor point 212 may be a cavity with a single opening formed in the second surface 211. The second magnet 4 is placed in the cavity and forms a tight fit with the cavity.
In some other embodiments, the first magnet positioning point 112 may also be a cavity with a single opening formed protruding from the first surface 111.

The fourth injection-molded layer 22 is formed to cover the second surface 211 and the second magnet 4 to enclose the second magnet 4 between the third injection-molded layer 21 and the fourth injection-molded layer 22. It should be noted that the second injection molded layer is also one shot so that the second injection molded layer forms a complete appearance. When the second magnet 4 is placed at the second magnet positioning point 212, the second magnet 4 is a magnet having no magnetism. After the fourth injection molding layer 22 is completed, the second magnet 4 is magnetized, so that the influence of high-temperature injection molding on the magnetic size of the magnet is avoided.
It will be appreciated that in use, the front frame 2 can be easily attached to the main frame 1 due to the attraction of the first magnet 3 and the second magnet 4 to each other. Therefore, the first magnet 3 and the second magnet 4 are disposed so as to correspond to each other at the positions of the main frame 1 and the front frame 2, respectively, and the first magnet 3 and the second magnet 4 can be attracted to each other more favorably. Referring to fig. 1 to 4, the main frame 1 has four first magnets 3. Four second magnets 4 are provided on the front frame 2. The first magnet 3 and the second magnet 4 are positioned to correspond to each other.
