Description

Technical Field

[0001] The utility model relates to the technical field of hinge connection, in particular to a novel screwless spectacle hinge structure and temple. Background Art

[0002] Glasses are mainly composed of spectacle lenses and frames, which are used to improve eyesight, protect eyes or for decorative purposes. The main components of the spectacle frame include a frame, nose pads, hinge blocks, temples, etc. Among them, the frame and the nose pads are usually an integral structure, the frame and the hinge blocks are usually fixedly connected by welding, and the hinge blocks and the temples are hinged.

[0003] For example, in the Chinese utility model spectacle frame with the publication number CN219475927U, by providing a first counterbore on the first link block and a second counterbore on the second link block, the first fixing member and the second fixing member can be respectively inserted into the first counterbore and the second counterbore, thus avoiding the end face of the hinge being scratched by the mold and also avoiding gaps between the rivets and the end face of the hinge, so as to improve the riveting yield rate of the spectacle frame. However, such a structure still has the following several significant defects:

[0004] 1. The traditional steps of assembling the hinge of a hybrid spectacle frame usually require tools, such as a rivet gun, to drive the hinge into the corresponding part of the spectacle frame. This not only increases the tool cost of assembly, but also requires a high level of operation skills for the assembly workers; in large-scale production, workers need to spend time and effort to ensure the accuracy of hinge installation, otherwise quality problems such as skewed or loose hinge installation may occur;

[0005] 2. Since the head sizes of wearers are different, the encircling degree of temples with a fixed length cannot meet the requirement of firm wearing. In addition, in different wearing scenarios, such as when running or climbing, the wearing stability of the glasses will be significantly reduced and they are prone to slipping.

[0056] In the following, in combination with the accompanying drawings, a novel screwless eyeglass hinge structure and temples provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0057] Embodiment 1:

[0058] like Figures 1 to 3 As shown, an embodiment of the present application provides a new screwless eyeglass hinge structure for flexibly connecting an external frame 1 and an external temple 2, including a mounting member 3, which is plugged into both ends of the frame 1; a rubber plug 4, which is flexibly connected to the mounting member 3; and a temple head 5, which is arranged at the front end of the temple 2; wherein the temple head 5 is plugged into the rubber plug 4.

[0059] Furthermore, the mounting member 3 includes a pair of rounded rectangular plates 301 which are inserted into the mirror frame 1 ; and a bottom plate 302 which is fixedly connected to the bottom ends of the pair of rounded rectangular plates 301 ; wherein the bottom plate 302 is in contact with the mirror frame 1 .

[0060] Further, the mounting member 3 further includes a positioning hole 303 provided at one end of a pair of the rounded rectangular plates 301 away from the bottom plate 302; a notch 304 provided at one end of a pair of the rounded rectangular plates 301 away from the bottom plate 302 and communicating with the positioning hole 303; wherein, the rubber plug 4 is rotatably mounted in the positioning hole 303.

[0061] Further, an installation hole 6 is provided on the rubber plug 4.

[0062] Further, the foot screw head 5 includes a mounting plate 501 inserted into the installation hole 6; a sliding plate 502 having one end fixedly connected to the mounting plate 501 and the other end fixedly connected to the temple 2; wherein, the width of the mounting plate 501 is greater than the width of the sliding plate 502, the width of the sliding plate 502 is the same as the distance between a pair of the rounded rectangular plates 301, and the sliding plate 502 can slide between a pair of the rounded rectangular plates 301.

[0063] Further, it further includes a metal gasket 701 provided between the rubber plug 4 and the spectacle frame 1; a concave portion 702 provided on the metal gasket 701; a pair of openings 703 provided on the metal gasket 701; wherein, a pair of the rounded rectangular plates 301 can respectively pass through a pair of the openings 703.

[0064] In this embodiment of the present application, due to the above structure, the mounting member 3 sequentially passes through the spectacle frame 1 and the metal gasket 701. By inserting the rubber plug 4 into the positioning hole 303, the mounting member 3 and the metal gasket 701 are firmly fixed on the spectacle frame 1. The installation hole 6 is provided in the rubber plug 4. Rotate the rubber plug 4 to align the installation hole 6 on it with the notch 304 on a pair of the rounded rectangular plates 301, then the mounting plate 501 can be inserted into the installation hole 6. The rear end of the mounting plate 501 is fixedly connected to the sliding plate 502. Rotate the foot screw head 5 outward so that the sliding plate 502 is placed between a pair of the rounded rectangular plates 301, and the rubber plug 4 can only rotate around the positioning hole 303;

[0065] The concave portion 702 can increase the contact area with the rubber plug 4, thereby reducing the pressure of the rubber plug 4 on the spectacle frame 1 and effectively preventing the mounting member 3 from loosening;

[0066] In the assembled state, when the temple 2 is rotated, the temple 2 will drive the sliding plate 502 to slide between a pair of the rounded rectangular plates 301. During the opening and closing process of the temple 2, the sliding plate 502 and the notch 304 will never coincide, ensuring that the temple 2 will not easily slip off from the notch 304 when opened or closed.

[0067] Embodiment 2:

[0068] Such as Figure 1 、 Figure 4 AndFigure 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a temple having the novel screwless eyeglass hinge structure includes a rotating shaft 8, which is arranged at one end of the temple 2 away from the frame 1; and a temple tail 9, which is movably connected to the temple 2 via the rotating shaft 8.

[0069] Furthermore, it also includes a gear 10, which is fixedly connected to the rotating shaft 8; and a gear block 11, which is arranged at one end of the temple 2 close to the temple tail 9.

[0070] Furthermore, it also includes a slide groove 12, which is arranged on the temple 2; a slider 13, which is arranged in the slide groove 12, and the slider 13 can slide in the slide groove 12; wherein the slider 13 is fixedly connected to the tooth block 11.
