[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures.

To better illustrate the embodiments of this utility model, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the figures for those skilled in the art.

[0020] In the figures of this utility model embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0021] like Figures 1-4 As shown, this utility model provides an adjustable pair of glasses, including a pin 3 for connecting the frame 1 and the temple 2. One end of the pin 3 is hinged to the temple 2, and the other end is detachably connected to the frame 1. The two ends of the pin 3 extend at a first angle. In this embodiment, the first angle is 90°. Pins 3 with different angles can also be customized as needed to make the glasses suitable for users with different head shapes.

[0022] In this embodiment, a blind groove 11 is provided at the connection between the frame 1 and the pile head 3. An elastic cover plate 12 extends from the blind groove 11. The elastic cover plate 12 has a first arc tooth portion 121 along its length. One end of the pile head 3 is provided with an extension strip 31. The extension strip 31 is provided with a second arc tooth portion 32 that matches the first arc tooth portion 121. The ends of the elastic cover plate 12 extend to both sides with ear seats 122 having threaded holes.

[0023] The first arc-shaped tooth section 121 includes several continuous arc-shaped grooves of equal width. The width of the arc-shaped grooves is a specific value and is marked above the blind groove 11. When it is necessary to adjust the inner and outer width of the frame, the screw in the ear seat 122 is loosened, so that the tail end of the elastic cover plate 12 is loosened. Then the extension strip 31 of the post head 3 can be slowly pulled to move the engagement position of the second arc-shaped tooth section 32 relative to the first arc-shaped tooth section 121. Then the screw in the ear seat 122 is tightened to complete the adjustment. Although this design sacrifices a certain adjustment precision, making the minimum value of a single adjustment the width of the arc-shaped groove, it simplifies the adjustment method of the post heads 3 on both sides of the frame 1, while ensuring the accuracy of each adjustment.

[0024] In this embodiment, the elastic modulus of the elastic cover plate 12 is 2.8-3.5 GPa, and the coefficient of friction of the elastic cover plate 12 is 0.1-0.3. For example, the material can be polyacetal or acetal oxide (POM), which is chemically stable at room temperature, releases no volatile substances, complies with RoHS and REACH environmental standards, and is safe for direct skin contact. By setting a relatively large elastic modulus and coefficient of friction, the mechanical properties of the elastic cover plate 12 can be utilized to ensure that the screw inside the ear seat 122 is prone to lateral stress deformation, making the screw less likely to loosen.

[0025] In this embodiment, the two frames 1 are connected by a central beam. The central beam adopts a telescopic structure. Such telescopic structures applied to the central beam are quite common. The specific structure and principle will not be described in detail here. In addition, the frames 1 are provided with nose pads, and lenses are snapped into the frames 1. The ends of the temples 2 are provided with rubber sleeves.

[0026] In this embodiment, adjustments can be made in conjunction with adjusting the head and the central beam structure to ensure that the centering amount is ≤3mm. The centering amount refers to the offset of the optical center point of the lens relative to the geometric center point of the frame. The purpose of adjusting the centering amount is to align the optical center with the pupil, making it more comfortable and clear to wear.

[0027] In this embodiment, a flexible shield 4 is also provided between the frame 1 and the post head 3. The flexible shield 4 allows the width distance between the frame 1 and the post head 3 to be adjusted inside the shield, thus not affecting the aesthetic appearance and preventing dust accumulation in the gap between the post head 3 and the frame 1 or skin scratches from the sharp edges.

[0028] The working principle of this utility model is as follows:

[0029] When adjusting the eyeglasses of this invention, loosen the screws inside the earpiece 122 to loosen the tail end of the elastic cover plate 12. Then, slowly pull the extension strip 31 of the post head 3 to move the engagement position of the second arc tooth part 32 relative to the first arc tooth part 121. Finally, tighten the screws inside the earpiece 122 to complete the adjustment. During this process, the minimum adjustment value in a single operation is the width of the arc groove, simplifying the adjustment method of the post heads 3 on both sides of the frame 1. It can also be used in conjunction with adjusting the post head and the center beam structure to ensure that the center displacement is ≤3mm.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
