Technical Field

[0001] This utility model relates to modular eyeglasses, and more particularly to a magnetic eyeglasses that is easy to assemble. Background Technology

[0002] Combination glasses are a design that combines the features of two or more eyewear functions to meet the wearer's needs in different environments. The most common combination is to combine optical lenses that correct vision with sunglasses lenses that provide sun protection.

[0003] Existing magnetic glasses have a groove in the main frame, and a magnet is placed in the groove and glued together. If the magnet is subjected to a force in the front-back direction, it is very easy for the magnet to fall out of the groove, which will affect the connection stability between the main frame and the secondary frame. Therefore, how to make the magnet stably located in the main frame has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic eyeglass that is easy to assemble, in which the limiting segment and the mating segment work together to limit the main magnet installed in the mounting groove so that it can be stably positioned in the mounting groove.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a main frame and a secondary frame, with a main magnet on the main frame and a secondary magnet on the secondary frame. The main magnet and the secondary magnet attract each other. It also includes a limiting member located within and fixedly connected to the main frame. The limiting member includes a front mounting plate and a rear mounting plate. The rear mounting plate has a mounting groove for inserting the main magnet. The rear mounting plate includes a limiting section located to the right of the mounting groove. The front mounting plate includes a mating section located to the left of the limiting section. The mating section is located in front of the limiting section, and its rear end face abuts against the front end face of the main magnet.

[0006] The present invention is further configured such that: the limiting member includes a mounting base located below the front mounting plate and the rear mounting plate, the mounting base is provided with a connecting beam protruding upward, one end of the connecting beam is fixedly connected to the limiting section, and the other end is fixedly connected to the mating section.

[0007] The present invention is further configured such that the limiting member also includes an injection molding groove located below the mounting groove.

[0008] The present invention is further configured such that the front end face of the connecting beam abuts against the rear end face of the main magnet.

[0009] The present invention is further configured such that: the main magnet includes a contact surface on the front side that attracts the secondary magnet, and the contact surface is inclined from front to back and from right to left.

[0010] The present invention is further configured such that the mounting base is provided with a hinge portion.

[0011] The present invention is further configured such that: the mounting base is provided with an upper limit slot and a lower limit slot at its upper and lower ends respectively; the main frame is provided with a mounting position for inserting the limiting component; the mounting position includes an upper limit plug and a lower limit plug respectively provided for the upper limit slot and the lower limit slot.

[0012] The present invention is further configured such that: a temple is hinged to the secondary frame, a positioning block is provided on the temple, and a positioning slot is provided on the secondary frame located on the rotation trajectory of the positioning block.

[0013] By adopting the above technical solution, during the process of fixing the main magnet to the limiting member, after the main magnet is placed into the mounting groove, the front end face of the main magnet will abut against the rear end face of the mating section, and the circumference of the main magnet will fit against the front mounting plate. Thus, before the main magnet is fixed to the main frame, if the main magnet is pushed forward, the main magnet will not move forward and detach from the mounting groove due to the restriction of the mating section. This allows the main magnet to be stably positioned in the mounting groove of the limiting member, reducing the occurrence of displacement and detachment of the main magnet during movement. This provides convenience for fixing the main magnet to the limiting member and fixing the limiting member to the main frame. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6As shown, this utility model discloses a magnetic eyeglass that is easy to assemble, including a main frame 1 containing optical lenses and a secondary frame 2 containing lenses of a different type, such as sunglasses lenses or 3D lenses. The main frame 1 is provided with a main magnet 11, and the secondary frame 2 is provided with a secondary magnet (not shown in the figure) and an insertion slot 21 for inserting the secondary magnet. The main magnet 11 and the secondary magnet attract each other, thereby connecting the main frame 1 and the secondary frame 2, allowing the secondary frame 2 to be stably positioned in front of the main frame 1 (this is prior art and will not be described in detail here). It also includes a limiting member 3, which is located inside the main frame 1 and fixedly connected to the main frame 1 by injection molding, welding, or other methods. The limiting member 3 includes a front mounting plate 31 and a rear mounting plate 32. The rear mounting plate 32 is provided with a mounting slot 321 for inserting the main magnet 11. The rear mounting plate 32 includes a mounting slot 321 located on the right side of the mounting slot 321. The limiting section 322, the front mounting plate 31 includes a mating section 311 located on the left side of the limiting section 322. The mating section 311 is located in front of the limiting section 322 and its rear end face abuts against the front end face of the main magnet 11. During the process of fixing the main magnet 11 onto the limiting member 3, after the main magnet 11 is placed into the mounting groove 321, the front end face of the main magnet 11 will abut against the rear end face of the mating section 311, and the circumferential direction of the main magnet 11 will be aligned with the front mounting plate 322. The mounting plate 31 is attached so that before the main magnet 11 is fixed to the main frame 1, if the main magnet 11 is pushed forward, the main magnet 11 will not move forward and disengage from the mounting groove 321 due to the restriction of the mating section 311. This allows the main magnet 11 to be stably located in the mounting groove 321 of the limiting member 3, reducing the occurrence of displacement and falling off of the main magnet 11 during movement. This facilitates the fixing of the main magnet 11 to the limiting member 3 and the fixing of the limiting member 3 to the main frame 1.

[0027] It is also worth noting that in this embodiment, there are two limiting members 3, which are the same in shape and size and are fixedly connected to the left and right sides of the main frame 1 respectively.

[0028] The limiting member 3 includes a mounting base 33 located below the front mounting plate 31 and the rear mounting plate 32. The mounting base 33 has a connecting beam 331 protruding upward. One end of the connecting beam 331 is fixedly connected to the limiting section 322 by integral molding or other means, and the other end is fixedly connected to the mating section 311 by integral molding or other means. Since the connecting beam 331 is located below the main magnet 11, it can provide support for the main magnet 11 when it is installed into the mounting groove 321. Furthermore, since one end of the connecting beam 331 is fixed to the limiting section 322 and the other end is fixed to the mating section 311, the limiting section 322 and the mating section 311 can be stably positioned on the limiting member 3, thus stably limiting the main magnet 11 when it is installed into the mounting groove 321.

[0029] The limiting member 3 also includes an injection groove 34 located below the mounting groove 321. The injection groove 34 can be used to assist in the injection of materials during the manufacturing process, and provides convenience for fixing the main magnet 11 and the limiting member 3.

[0030] The upper end face of the connecting beam 331 abuts against the bottom surface of the main magnet 11. Since the front end face of the connecting beam 331 abuts against the bottom surface of the main magnet 11, the connecting beam 331 can further facilitate the determination of the position of the main magnet 11 in the mounting groove 321 and reduce the possibility of the main magnet 11 falling into the injection molding groove 34.

[0031] Preferably, the main magnet 11 includes a contact surface 111 on the front side that attracts the secondary magnet. The contact surface 111 is inclined from front to back and from right to left. The inclined contact surface 111 allows the secondary magnet to be fixed on the secondary frame 2. After the main magnet 11 is placed in the limiting member 3, the contact surface between the frontmost side of the secondary magnet and the main magnet 11 can achieve attraction between the two, thus enabling the main magnet 11 and the secondary magnet to complete the connection more smoothly and efficiently.

[0032] Furthermore, the mounting base 33 is provided with a hinge portion 332. Since the mounting base 33 is provided with a hinge portion 332, after the temple is mounted on the hinge portion 332, the temple can be rotated relative to the main frame 1. This allows the temple to be rotated outward to wear the glasses when they need to be used, and to be rotated inward when the glasses are stored, so that the temple is located behind the main frame 1 and is in a stored state.

[0033] The mounting base 33 is provided with an upper limit slot 333 and a lower limit slot 334 at its upper and lower ends, respectively. The main frame 1 is provided with a mounting position 12 for inserting the limiting member 3. The mounting position 12 includes an upper limit plug 121 and a lower limit plug 122 respectively corresponding to the upper limit slot 333 and the lower limit slot 334. Therefore, during the process of inserting the limiting member 3 into the main frame 1, the upper limit plug and the lower limit plug on the main frame 1 will be inserted into the upper limit slot 333 and the lower limit slot 334, respectively, which facilitates the determination of the relative position of the limiting member 3 and the main frame 1.

[0034] In addition, a temple 4 is hinged to the secondary frame 2, and a positioning block 41 is provided on the temple 4. A positioning slot 22 is provided on the rotation trajectory of the positioning block 41 in the secondary frame 2. The positioning block 41 on the temple 4 makes it convenient to install the temple 4 into the secondary frame 2 when the temple 4 is installed into the secondary frame 2.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
