Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a magnetic elastic temple and glasses. Background Art

[0002] The temple is a main component of glasses, used for hinging with the frame. When wearing glasses, it plays a supporting role for the frame and the lenses arranged in the frame. In order to ensure the stability of wearing glasses, two temples are provided on a pair of glasses. Only when the distance between the two temples matches the width of the human face can the best wearing comfort and stability be achieved. In the prior art, in order to adapt to different widths of human faces, the temples of glasses generally use materials with certain elasticity to make the temples, or elastic parts such as springs and elastic sheets are arranged at the connection between the temples and the frame. However, for the former, due to the small elastic deformation range of the temples, it cannot well adapt to different widths of human faces with a large span. For the latter, due to the elastic fatigue of elastic parts such as springs and elastic sheets, the durability cannot be guaranteed.

[0003] In view of the above problems, the utility model is improved. Summary of the Utility Model

[0004] The utility model provides a magnetic elastic temple and glasses, which solve the above problems existing in the prior art during use.

[0005] The technical solution of the utility model is realized as follows:

[0006] A magnetic elastic temple includes a temple body, which is composed of a fixed section and an adjustment section. The front end of the adjustment section is hinged to the rear end of the fixed section, and an installation part is formed on the front end of the adjustment section on one side of the outer surface of the fixed section. A first magnet and a second magnet are respectively embedded on the opposite surfaces of the installation part and the fixed section, and the repulsive magnetic poles of the first magnet and the second magnet are opposite to each other.

[0007] Preferably, a hinge part is formed on the front end surface of the adjustment section, a hinge groove matching the hinge part is opened on the rear end surface of the fixed section, and the hinge part extends into the hinge groove and is hinged to the fixed section through a hinge shaft.

[0008] Preferably, a swing cavity is formed inside the rear end of the fixed section. A swing window communicating with the swing cavity and allowing the front end of the installation part to swing through is opened on the outer surface of the fixed section. A swing channel communicating with the swing cavity and allowing the rear end of the installation part to swing and located outside the hinge groove is opened on the rear end surface of the fixed section. The installation part passes through the swing channel and extends into the swing cavity, and the second magnet is embedded on the side wall of the swing cavity opposite to the installation part.

[0009] Preferably, a first arc surface concentric with the hinge shaft is formed on the rear end surface of the fixed section, and a second arc surface matching and fitting with the first arc surface is formed on the front end surface of the adjusting section.

[0010] Preferably, a limiting portion is formed on the outer side surface of the adjusting section, and the limiting portion can abut against the rear end surface of the fixed section when the adjusting section swings.

[0011] Preferably, a plurality of anti-slip protrusions are formed on the outer side surface of the adjusting section.

[0012] A pair of glasses comprises two such magneto-elastic temple arms.

[0013] In summary, the beneficial effects of the present utility model are as follows: due to the repulsive effect between the first magnet and the second magnet, the mounting portion has a tendency to swing outwards, and the adjusting section has a tendency to swing inwards. When wearing the glasses, the adjusting section can swing inwards by different amplitudes according to the width of different faces due to the inward swinging tendency, so that the adjusting section fits the inner side of the human ear. Therefore, such magneto-elastic temple arms can be adapted to faces with different widths. Moreover, the adjusting section has a large swing amplitude relative to the fixed section, and can be adapted to faces with larger spans and different widths, having better applicability. In addition, the swinging tendency of the adjusting section is realized by the cooperation of the first magnet and the second magnet, without the problem of elastic fatigue of the elastic member, thus improving the durability of the elastic swing of the temple arms.

[0021] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying Figures 1-5 drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in the figure, a magnetic elastic temple includes a temple body 1. The temple body 1 is composed of a fixed section 11 and an adjustment section 12. The front end of the adjustment section 12 is hinged to the rear end of the fixed section 11, and a mounting portion 121 located on one side of the outer surface of the fixed section 11 is formed at the front end of the adjustment section 12. A first magnet 122 and a second magnet 111 are respectively embedded on the opposite surfaces of the mounting portion 121 and the fixed section 11, and the mutually repulsive magnetic poles of the first magnet 122 and the second magnet 111 are opposite.

[0023] Specifically, the structure in which the front end of the adjustment section 12 is hinged to the rear end of the fixed section 11: A hinge portion 123 is formed on the front end surface of the adjustment section 12, a hinge groove 112 matching the hinge portion 123 is opened on the rear end surface of the fixed section 11, and the hinge portion 123 extends into the hinge groove 112 and is hinged to the fixed section 11 through a hinge shaft 13.

[0024] In the above structure, the front section of the fixed section 11 is hinged to the spectacle frame to realize the connection between the temple body 1 and the spectacle frame. When the temple is unfolded, due to the repulsive action between the first magnet 122 and the second magnet 111, the mounting portion 121 has a tendency to swing away from the fixed section 11 along the hinge shaft 13, that is, the adjustment section 12 has a tendency to swing inward along the hinge shaft 13. When wearing glasses, due to the tendency of the adjustment section 12 to swing inward, the adjustment section 12 can swing inward by different amplitudes according to the width of different faces, so that the adjustment section 12 fits the inner side of the human ear. This magnetic elastic temple can be adapted to faces of different widths, and the adjustment section 12 has a large swing amplitude on the fixed section 11, can be adapted to faces of different widths with a larger span, has better applicability, and the swinging tendency of the adjustment section 12 is realized by the cooperation of the first magnet 122 and the second magnet 111, without the problem of elastic fatigue of the elastic member, and improves the durability of the elastic swing of the temple.

[0025] In addition, on the basis of the above structure, a swing cavity 113 is formed inside the rear end of the fixed section 11. A swing window 114 communicating with the swing cavity 113 and allowing the front end of the mounting portion 121 to swing through is provided on the outer side surface of the fixed section 11. A swing channel 115 communicating with the swing cavity 113 and allowing the rear end of the mounting portion 121 to swing and located outside the hinge groove 112 is provided on the rear end surface of the fixed section 11. The mounting portion 121 passes through the swing channel 115 and extends into the swing cavity 113. The second magnet 111 is embedded on the side wall of the swing cavity 113 opposite to the mounting portion 121. When the mounting portion 121 swings under the action of the first magnet 122 and the second magnet 111, its front end remains swinging within the swing channel 115, and the swing channel 115 applies a limit to the outward swing of the mounting portion 121. When the glasses are not worn, the limit applied to the outward swing of the mounting portion 121 through the swing channel 115 causes the adjustment section 12 to be in a position relatively parallel to the fixed section 11, that is, the spectacle leg body 1 formed by the front-to-back connection of the adjustment section 12 and the fixed section 11 is in a relatively straight state, which facilitates threading the adjustment section 12 between the face and the ear when wearing the glasses, thus facilitating the wearing of the glasses. The swing cavity 113 and the swing window 114 provide space for the swing of the mounting portion 121, ensuring that the mounting portion 121 has a large swing amplitude and thus ensuring that the adjustment section 12 has a large swing amplitude, enabling the adjustment section 12 to swing and adapt to faces of different widths with a larger span, and ensuring the applicability of this magneto-elastic spectacle leg.

[0026] In addition, on the basis of the above structure, a first arc surface 116 concentric with the hinge shaft 13 and in an arc shape is formed on the rear end surface of the fixed section 11. A second arc surface 124 matching the first arc surface 116 and fitting with the first arc surface 116 is formed on the front end surface of the adjustment section 12. When the adjustment section 12 swings along the hinge shaft 13, the first arc surface 116 and the second arc surface 124 remain in contact. The cooperation of the first arc surface 116 and the second arc surface 124 provides support and guidance for the swing of the adjustment section 12 relative to the fixed end, ensuring the stability of the adjustment section 12 during swinging, and thus ensuring the durability of this magneto-elastic spectacle leg.

[0027] Additionally, based on the above structure, a limiting portion 125 is formed on the outer side surface of the adjusting section 12. When the limiting portion 125 swings with the adjusting section 12, it can abut against the rear end surface of the fixed section 11. That is, when the mounting portion 121 swings inward and drives the adjusting section 12 to swing outward to a certain extent, the limiting portion 125 abuts against the rear end surface of the fixed section 11. Through the action of the limiting portion 125, limits are imposed on the inward swing of the mounting portion 121 and the outward swing of the adjusting section 12, preventing the adjusting section 12 from swinging outward excessively and forcing the mounting portion 121 to swing inward and overly contact the inner wall of the swing cavity 113, which may cause the mounting portion 121 to be overly stressed and break, thereby ensuring the durability of this magnetic elastic temple.

[0028] Additionally, based on the above structure, a number of anti-slip protrusions 126 are formed on the outer side surface of the adjusting section 12. When wearing glasses and inserting the adjusting section 12 between the face and the ear, the anti-slip protrusions 126 contact the inner side surface of the ear, increasing the friction between the adjusting section 12 and the ear, thereby improving the stability of the glasses when worn.

[0029] A pair of glasses includes two such magnetic elastic temples. The front end of the fixed section 11 is hinged to the frame. Through the cooperation of the two magnetic elastic temples, the distance between the two temples of the glasses can be adjusted according to the face widths of different people, improving the comfort and stability of the glasses when worn.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
