Detailed Description of the Preferred Embodiment

[0020] Embodiment 1

[0021] As Figures 1 - 4 shown, a non-loosening slingshot box proposed in this embodiment includes a first connecting frame 1, a second connecting frame 2 and an elastic member.

[0022] The first connecting frame 1 has a "return" - shaped structure with a through - installation channel. The first connecting frame 1 has limiting reverse teeth 101. On the one hand, the limiting reverse teeth 101 are used to limit the second connecting frame 2, and on the other hand, they are used for anti - detachment limit when inserted into the groove at the end of the temple. The raw material of the first connecting frame 1 is a sheet - like structure, and it is formed into a "return" - shaped structure through bending processing.

[0023] The second connecting frame 2 has a U - shaped structure, is inserted through the installation channel, has a hinge hole 201 at the outer end, and has a limiting table portion 202 that limits the movement range of the limiting reverse teeth 101. The second connecting frame 2 and the first connecting frame 1 are slidably connected. The raw material of the second connecting frame 2 is a sheet - like structure, and it is formed into a U - shaped structure through bending processing.

[0024] As Figure 2 shown, the elastic member is located inside the installation channel and is tensioned between the first connecting frame 1 and the second connecting frame 2. When the elastic member is opened to the maximum length, the limiting reverse teeth 101 are in contact with the limiting table portion 202. The elastic member is a spring 3, and other elastic structures can also be used, such as elastic rubber strips, which can also elastically tension the first connecting frame 1 and the second connecting frame 2.

[0025] An observation hole 103 facing the elastic member is provided on the first connecting frame 1 to position the elastic member inside the installation channel, ensuring that the elastic member is installed in the center. The observation hole 103 can be a strip-shaped hole, distributed along the length direction of the elastic member, so that the observation range is longer.

[0026] In this embodiment, it is hingedly connected to the spectacle frame through the hinge hole 201 of the second connecting frame 2, and clamped to the spectacle leg through the limiting reverse teeth 101 of the first connecting frame 1, without thread slipping and not easily loosening and falling off. Both the first connecting frame 1 and the second connecting frame 2 are sheet materials, and are processed by bending. The processing technology is simple, and the elastic member can directly use the existing spring 3.

[0027] Embodiment 2

[0028] As Figures 1 - 4 shown, for an anti-loosening slingshot case proposed in this embodiment, compared with Embodiment 1, in this embodiment, a plurality of limiting reverse teeth 101 are arranged horizontally side by side, and the outward protruding distance of the limiting reverse teeth 101 gradually decreases along the direction away from the limiting platform portion 202, that is, the outer ends of the plurality of limiting reverse teeth 101 are inclinedly distributed, which can guide the process of inserting the first connecting frame 1 into the slot at the end of the spectacle leg, improve the smoothness of the insertion, and the limiting reverse teeth 101 can ensure that it is not easily loosened after the insertion is completed.

[0029] To improve the smoothness of the installation of the first connecting frame 1, the end of the first connecting frame 1 away from the hinge hole 201 is extended, and a guiding inclined surface 102 is provided at the extended part, so that when the first connecting frame 1 is inserted into the slot of the spectacle leg, the insertion can be more smooth.

[0030] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which it belongs, various changes can be made without departing from the purpose of the present invention.
