Description

Technical Field

[0001] This utility model belongs to the field of eyeglass frame technology, and specifically relates to a temple connection structure with mortise and tenon joints. Background Technology

[0002] Eyeglasses are increasingly widely used in daily life as a vision correction tool and a means of shading. The eyeglass frame mainly consists of a frame and two temples. The frame has a base, and the temples are connected to the base via hinges. The two temples are located on both sides of the frame and can be hooked around the wearer's ears for secure wearing.

[0003] Currently, eyeglass frames on the market typically use threaded hinges to connect the temples and the frame head, resulting in a complex structure, heavy weight, and poor wearing comfort.

[0004] For example, the existing patent with application number CN202221118530.2 discloses an integrally molded eyeglass frame, including temples, hinges, fasteners, headbands, and eyeglass frames. The hinges include a front hinge and a rear hinge. The temples and the rear hinge are integrally molded from sheet material. The rear hinge has a second cylinder bent from sheet material. The eyeglass frames, headbands, and front hinges are integrally molded from sheet material. The front hinge is connected to the eyeglass frames through a headband. The front hinge has a first cylinder bent from sheet material. The side of the first cylinder has a receiving cavity. The second cylinder is inserted into the receiving cavity and fixed by the fasteners. The fasteners include a threaded sleeve, a first sleeve rod, a second sleeve rod, and a screw. The screw passes through the second sleeve rod, the first cylinder, and the first sleeve rod in sequence and is screwed into the threaded sleeve. The frame is integrally molded from sheet material.

[0005] The eyeglass frames disclosed in the aforementioned patent use screw hinges to connect the head and temples. While this design offers the advantage of easy opening and closing, it also suffers from complex structure, heavy weight, and poor wearing comfort. Utility Model Content

[0006] To address the aforementioned issues, the primary objective of this invention is to provide a temple connection structure with a mortise and tenon joint, which eliminates the need for screws, simplifies the structure, facilitates assembly and disassembly, and enhances wearing comfort.

[0007] Another objective of this invention is to provide a temple connection structure with mortise and tenon joints, which makes the connection more stable, less prone to loosening or falling off, and can extend the service life of eyeglasses.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] This utility model provides a temple connection structure with a mortise and tenon structure, including: a frame and temples. The frame has a post at one end, and a rotating post is provided on the end face of the post. The temple has a post connection part near the post, and the post connection part has a rotating groove. The inner wall of the rotating groove has a riveting protrusion. The rotating post has a riveting hole. The rotating post is rotatably connected to the rotating groove, and the riveting protrusion is rotatably installed in the riveting hole. The edge of the rotating post is also provided with a slope to facilitate the riveting protrusion to be assembled into the riveting hole.

[0010] Furthermore, the inner side of the pile head connection is provided with a first limiting piece and a second limiting piece with a distance between them. The first limiting piece and the second limiting piece are arranged vertically opposite each other, forming the rotation groove between them. There are two riveting protrusions, which are located on the inner walls of the first limiting piece and the second limiting piece, respectively, and are arranged vertically opposite each other.

[0011] Furthermore, the first limiting plate and the second limiting plate have a limiting surface at one end opposite to the end face of the pile head. The limiting surface includes an arc surface for limiting the rotation of the temple and a plane surface for positioning the unfolding of the temple. The arc surface and the plane surface are connected.

[0012] Furthermore, the connecting part of the eyeglass head is provided with a positioning protrusion protruding from the first and second limiting plates on the side near the eyeglass head. When the temple is unfolded, the end face of the positioning protrusion abuts against the end face of the eyeglass head. In this application, when the eyeglass temple is unfolded, the positioning protrusion allows the plane of the limiting surface to maintain a certain distance from the end face of the eyeglass head, thereby maintaining a certain opening and closing allowance. This allows for a certain degree of assembly freedom between the eyeglass temple and the eyeglass head, accommodating certain dimensional errors, and also reduces contact wear between the eyeglass temple and the eyeglass head.

[0013] Furthermore, the pile head connection has an opening on the side opposite to the first limiting plate and the second limiting plate that communicates with the rotating groove, which can facilitate the cleaning of foreign objects in the rotating groove and also has an anti-air effect, reducing the wear of the rotating column.

[0014] Compared with the prior art, the advantages of this utility model are as follows: This application uses a riveting structure formed by riveting protrusions and riveting holes to position the rotation between the pin and the temple of the glasses. No screws are needed, the structure is simpler, and it is convenient to assemble and disassemble, which can improve the wearing comfort. At the same time, the riveting structure is more stable and less likely to loosen or fall off, which can extend the service life of the glasses. The slope set on the edge of the rotating column can easily assemble the riveting protrusion into the riveting hole, which can improve the ease of assembly. Attached Figure Description
