Description

Technical Field

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

[0002] An elastic glasses frame is a kind of glasses with an elastic sheet structure added at the hinge joint between the lens frame and the frame arm. Through the elastic sheet structure, the frame arm can be quickly opened or closed in place, avoiding being poked by the freely rotating frame arm on the face during the process of wearing glasses, thus improving the convenience of wearing glasses.

[0003] However, traditional elastic glasses frames have more accessories. For example, the patent number 201020604240.X discloses an outer-elastic-sheet glasses frame and glasses, which include a lens frame for carrying lenses, hinge heads hinged to both sides of the lens frame, frame arms fixedly connected to the hinge heads, and elastic sheets. During installation, the elastic connection between the frame arm and the lens frame can only be achieved through the transfer of the hinge head, increasing the difficulty of production and assembly and raising the production cost. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the background art, the technical solution adopted by the utility model is: a simple elastic glasses frame, including a stud member for connecting the glasses frame and a frame arm connected to the stud member. The frame arm is provided with an integrally bent and formed circular ring portion and an elastic portion. The stud member is provided with a connecting block, the connecting block is provided with a limiting surface for abutting against the elastic portion, and the connecting block is provided with a mounting hole coaxially distributed with the circular ring portion. The frame arm is rotatably connected to the stud member through the mounting hole.

[0005] By adopting the above technical solution, the frame arm forms an elastic portion after wire cutting and is bent to form a circular ring portion, enabling the frame arm to simultaneously serve the functions of hinging the stud member and elastic positioning. Compared with the structure of traditional elastic glasses frames, the number of accessories is reduced, the installation process is simplified, and the production cost is saved.

[0006] The utility model is further provided that one side of the outer side surface of the stud member is provided with a side convex block, and a receiving groove for receiving the circular ring portion is formed between the side convex block and the connecting block.

[0007] Furthermore, the circular ring portion is arranged on both sides of the elastic portion, and the outer side surface of the elastic portion is coplanar with the outer side surface of the stud member. The side convex block is provided with an arc groove for receiving the elastic portion, and the top end of the elastic portion is arc-shaped.

[0008] Furthermore, the limiting surface includes a first plane and a second plane circumferentially distributed with the mounting hole as the axis.

[0009] By adopting the above technical solution, the two sets of limiting surfaces of the connecting block correspond to the open or closed state of the frame arm respectively. When the frame arm is rotated to open, the elastic part abuts against the arc groove to prevent the frame arm from turning outward.

[0010] The utility model is further configured that a gap is provided between the annular portion and the elastic portion.

[0011] By adopting the above technical solution, a gap is formed in the frame arm after wire cutting, and at the same time, the elastic part is prevented from interfering with the circular ring part during the deformation process, thereby maintaining the stability of the structure.

[0012] The utility model is further configured that the annular portion is provided with an inner hole for accommodating a fastening pin, and the frame arm is connected with a pile head piece via the inner hole pin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The frame arm is formed into an elastic part through wire cutting and bent into a circular ring part, so that the frame arm can take into account the role of the hinged pile head and the elastic positioning function at the same time. Compared with the traditional elastic glasses frame structure, it has fewer accessories, simplifies the installation process and saves production costs.

[0015] The embodiments of the utility model are further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-3As shown in the figure, this embodiment provides a simple elastic spectacle frame, which includes a ferrule member 1 for connecting the spectacle frame and a spectacle frame arm 2 connected to the ferrule member 1. The spectacle frame arm 2 is provided with an integrally bent and formed circular ring portion 21 and an elastic portion 22. The ferrule member 1 is provided with a connecting block 11. The connecting block 11 is provided with a limiting surface 12 for abutting against the elastic portion 22. The connecting block 11 is provided with a mounting hole 13 coaxially distributed with the circular ring portion 21. The spectacle frame arm 2 is rotatably connected to the ferrule member 1 through the mounting hole 13.

[0023] Combined with Figure 4 、 5 As shown in the figure, in this embodiment, a side convex block 14 is provided on one side of the outer side surface of the ferrule member 1, and a receiving groove 15 for receiving the circular ring portion 21 is formed between the side convex block 14 and the connecting block 11. The circular ring portion 21 is provided on both sides of the elastic portion 22, and the outer side surface of the elastic portion 22 is coplanar with the outer side surface of the ferrule member 1. The side convex block 14 is provided with an arc groove 16 for receiving the elastic portion 22, and the top end of the elastic portion 22 is arc-shaped. The limiting surface 12 includes a first plane 17 and a second plane 18 circumferentially distributed with the mounting hole 13 as the axis. A gap 23 is provided between the circular ring portion 21 and the elastic portion 22. The circular ring portion 21 is provided with an inner hole 24 for receiving a fastening pin. The spectacle frame arm 2 is pin-connected to the ferrule member 1 through the inner hole 24.

[0024] In the present utility model, the spectacle frame arm 2 is formed by a stamping process and is formed into three parts after wire cutting. The middle part naturally forms the elastic portion 22, and the two side parts are bent to form the circular ring portion 21. A gap is naturally formed between the elastic portion 22 and the circular ring portion 21 to prevent the elastic portion 22 from interfering with the circular ring portion 21 during the deformation process. The spectacle frame arm 2 is rotatably connected to the ferrule member 1 through a pin.

[0025] The working principle of the present utility model is that when the spectacle frame arm 2 is rotated and opened, the connecting block 11 forces the elastic portion 22 to deform and generate potential energy, so that the abutting surface of the elastic portion 22 is transferred from the first plane 17 to the second plane 18. Through the kinetic energy generated when the elastic portion 22 returns to its original position, the spectacle frame arm 2 is automatically perpendicular to the spectacle frame. At this time, the elastic portion 22 is caught in the arc groove 16 to prevent the spectacle frame arm 2 from turning outwards; conversely, when the spectacle frame arm 2 is closed, the abutting surface of the elastic portion 22 is transferred from the second plane 18 to the first plane 17, so that the spectacle frame arm 2 is automatically parallel to the spectacle frame, making it more convenient to wear the glasses.

[0026] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
