Description

Technical Field

[0001] The utility model relates to the technical field of glasses accessories, in particular to a four-leg slingshot structure. Background Art

[0002] The glasses slingshot is used for connecting the temple and the frame. The glasses slingshot structure enables the temple to be able to expand outward by a small angle when in the open position. In this way, the glasses are more convenient to wear and can also clamp the wearer's head, making the glasses firmly worn.

[0003] The glasses slingshot usually includes a slingshot box and a core component. The slingshot box is fixed on the temple, and the hinge head in the core component is hinged with the hinge on the frame stud. The way the slingshot box is fixed on the temple: If the temple is made of metal, the slingshot box is usually fixed on the temple by welding. For example, both the glasses with a nailed hinge metal slingshot with the patent number CN203799138U and a fixing method of a slingshot box and a glasses leg with the patent CN104148793B mention it. However, if the temple is made of plastic, usually the existing slingshot box is fixed on the temple by gluing with glue, or when the temple is injection molded, the slingshot box is placed in a suitable position in the mold. Then the molten plastic is injected into the mold by an injection molding machine, and the slingshot box will be fixed after the plastic cools. However, during the use of the glasses slingshot, when the temple is bent for a long time, the glasses slingshot is subjected to relatively large forces. If the fixing of the slingshot box and the temple is not very firm and reliable, it is easy to come off. And the existing glasses slingshot structure fixed on the temple by the above two fixing methods is still not firm enough. Therefore, in view of this technical problem, this application makes improvements to the glasses slingshot structure. Summary of the Utility Model

[0030] Embodiment:

[0031] As Figures 1 to 11 shown, the present utility model discloses a four-foot slingshot structure, including a slingshot box 1 and a core component. The core component is cooperatively installed on the slingshot box 1. A first hook foot 21 and a second hook foot 22 are integrally formed on the bottom side of the slingshot box 1, and the first hook foot 21 and the second hook foot 22 are symmetrically arranged.

[0032] When fixing the present utility model on the plastic temple 4, place the present utility model at a suitable position in the mold. Then, inject the molten plastic into the mold through an injection molding machine. After the plastic cools, it will fix the present utility model. As Figure 9 shown in Figure 10 , pay attention to making the first hook foot 21 and the second hook foot 22 embed into the inside of the temple 4, so as to greatly improve the connection firmness between the slingshot box 1 and the temple.

[0033] Specifically, both the first hook foot 21 and the second hook foot 22 include a vertical portion 23 and a hook portion 24. The vertical portion 23 is integrally formed on the bottom side of the slingshot box 1 and extends vertically downward, and the hook portion 24 is integrally formed on the vertical portion 23. The hook portion 24 of the first hook foot 21 extends toward the side away from the second hook foot 22, and the hook portion 24 of the second hook foot 22 extends toward the side away from the first hook foot 21. Both the first hook foot 21 and the second hook foot 22 are inserted into the temple 4 through the vertical portion 23. With the arrangement of the hook portion 24, the connection firmness between the slingshot box 1 and the temple 4 can be further improved.

[0034] Furthermore, the first hook foot 21 and the second hook foot 22 are respectively located on the front and rear sides of the bottom side of the slingshot box 1. Among them, as Figure 2 shown in Figure 4 , both the first hook foot 21 and the second hook foot 22 are provided with two. The two first hook feet 21 are respectively located on the left and right sides of the bottom side of the slingshot box 1, and the two second hook feet 22 are also respectively located on the left and right sides of the bottom side of the slingshot box 1. The two first hook feet 21 and the second hook feet 22 can further improve the connection firmness between the slingshot box 1 and the temple 4. In addition, generally, there is a steel wire 5 inside the existing plastic temple 4 to improve the structural strength of the temple 4. Therefore, the two first hook feet 21 and the second hook feet 22 can just be used to cooperate with the steel wire 5 inside the plastic temple 4. As Figure 9With Figure 10 As shown, let the steel wire 5 just pass through between the first hook feet 21 and the second hook feet 22 of the two, so as to further improve the structural strength between the slingshot box 1 and the temple arms.

[0035] In addition, in order to further improve the firmness of the steel wire 5 fitted between the first hook feet 21 and the second hook feet 22 of the two, as Figure 11 shown, positioning protrusions 25 are provided on the opposite sides of the two first hook feet 21 and on the opposite sides of the two second hook feet 22. In this way, when the steel wire 5 is clamped between the two first hook feet 21 and the second hook feet 22, an interference fit can be achieved through the positioning protrusions 25, so as to prevent the fit between the steel wire 5 and the two first hook feet 21 and the second hook feet 22 from coming off during the injection molding process of the temple arms.

[0036] As Figures 4 to 8 shown, an installation hole 11 with an opening facing forward is provided on the slingshot box 1. The core component is fitted in the installation hole 11. The core component specifically includes an integrally formed hinge head 31 and a long rod 32. A limiting plate 33 is fixedly connected to one end of the long rod 32 away from the hinge head 31. A limiting sleeve 34 and a spring 35 are sequentially sleeved on the long rod 32 from front to back, and the limiting sleeve 34 is limited on the slingshot box 1. The hinge head 31 is used for hinging with the hinge on the frame stud.

[0037] The specific structure in which the limiting sleeve 34 is limited on the slingshot box 1 is: a limiting card slot 341 is provided on the limiting sleeve 34, and a limiting plug post 36 is fixedly connected to the bottom side of the slingshot box 1. The limiting plug post 36 penetrates into the installation hole 11 and abuts in the limiting card slot 341.

[0038] At the same time, it should be pointed out that the terms of the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the protection scope of the present invention.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
