Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0021] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0023] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A self-disassembling metal eyeglass frame comprises a frame 1 and a hinge 2, wherein a metal strip 3 is fixedly connected to a side of the hinge 2 away from the frame 1, and an end of the metal strip 3 away from the hinge 2 is fixedly connected to a connecting metal sleeve 4 with an open side, an inner wall of the connecting metal sleeve 4 is provided with an internal thread 11, and an inner wall of the connecting metal sleeve 4 is provided with a plurality of arc-shaped grooves 5 of equal size, a connecting rod 6 is provided on the inner side of the connecting metal sleeve 4, and an external thread 12 is provided on the outer side of the connecting rod 6, a slide groove 7 of equal groove diameter is provided on the inner side of one end of the connecting rod 6, a spring 8 is provided on the inner side of the slide groove 7, a slider 9 is slidably connected to the inner side of the slide groove 7, a hemispherical block 13 is fixedly connected to one side of the slider 9, and a frame leg 10 is fixedly connected to the end of the connecting rod 6 away from the block 13.

[0026] The block 13 is arranged in a one-to-one correspondence with the slot 5, and several blocks 13 are arranged in an array with equal angles with the same center of a circle. The block 13 fits the inner wall of the slot 5. This arrangement allows the connecting rod 6 to be limited to a certain extent by the fit between the block 13 and the slot 5; the two ends of the spring 8 are fixedly connected to the inner wall of the slider 9 and the slide slot 7 respectively, and the slider 9 is arranged between the block 13 and the spring 8. This arrangement allows the block 13 to fit the slot 5 more closely under the elastic force of the spring 8; the metal strip 3 is arranged in a spiral shape, and there are two metal strips 3 in total. This arrangement can increase the bending amplitude and the bending ability of the eyeglass frame, and effectively solves the problem that the eyeglass frame is easily broken due to excessive force by the user; the inner wall of the connecting metal sleeve 4 fits the outer wall of the connecting rod 6, and the connecting metal sleeve 4 and the connecting rod 6 are spirally connected by the internal thread 11 and the external thread 12. This arrangement allows the connecting metal sleeve 4 to be spirally connected with the connecting rod 6, so as to facilitate the disassembly and assembly of the frame leg 10.

[0027] Working process: the mirror frame 1 is installed with the metal strip 3 through the hinge 2. When the frame leg 10 is installed, the connecting rod 6 is placed on the inner side of the connecting metal sleeve 4. The connecting rod 6 and the frame leg 10 are rotated. The connecting rod 6 is spirally connected with the connecting metal sleeve 4 through the external thread 12 on the outer side of the connecting rod 6 and the internal thread 11 on the inner side of the connecting metal sleeve 4. In the process of rotating the connecting rod 6, the connecting metal sleeve 4 will act on the block 13, and the block 13 will act on the slider 9, so that the slider 9 slides inside the slide groove 7, and the slider 9 will act on the spring 8 to squeeze the spring 8, so that The spring 8 is compressed, and when the block 13 moves to the slot 5 along with the connecting rod 6, the block 13 fits with the slot 5 under the elastic force of the spring 8, and the rotation of the connecting rod 6 is stopped. At this time, the frame leg 10 is connected with the connecting metal sleeve 4, that is, the installation of the frame leg 10 is realized. The reverse operation can realize the disassembly of the frame leg 10, and the spiral metal strip 3 set at the connecting metal sleeve 4 and the hinge 2 can increase the bending amplitude, thereby improving the bending ability of the glasses frame, and effectively solving the problem that the glasses frame is easily broken due to excessive force of the user.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
