Abstract
Description
Technical Field
[0001] This utility model belongs to the field of eyeglasses technology and relates to a connection structure between eyeglass frames and temples. Background Technology
[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. The frame consists of a frame, temples, and a hinge that connects the temples to the frame.
[0003] Existing eyeglass frames and temples are hinged together by connectors. For example, Chinese patent literature discloses a spring hinge between the temples and frame of eyeglasses [Patent No.: 200910226484.0; Application Publication No.: CN101738741B]. The spring hinge has two hinge components, each of which is connected to one of the eyeglass components. The first hinge component forms a support fork with a hinge axis for receiving the second hinge component. The second hinge component is guided so that it can move in the seat by means of a sliding component. The spring hinge also has a coil spring located between the two legs of the sliding component. One side of the coil spring is supported on a sheet of the sliding component connecting the two legs, and the other side is supported on a support post fixed to the seat. The seat has a closing component that forms a receiving opening for the connected first eyeglass component of the sliding component and forms a support post for the coil spring. The closing component formed by the seat forms an attachment flange that can be screwed onto the front side of the connected first eyeglass component.
[0004] This type of eyeglasses includes two hinge components: a hinge head and a spring-loaded assembly. The hinge head is fixedly connected to the frame, and the spring-loaded assembly is fixedly connected to the temple. The hinge head and the spring-loaded assembly are hinged together, thus connecting the frame and temple. However, in this type of eyeglasses, the hinge head is fixed to the frame with screws. Screws can loosen, resulting in poor stability and causing the temples to move loosely relative to the frame. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a connection structure for eyeglass frames and temples, thereby solving the technical problem of how to improve the stability of the connection between the frames and temples.
[0006] The purpose of this utility model can be achieved through the following technical solution: a connection structure between an eyeglass frame and temples, wherein the frame is made of plastic material, and the connection structure includes a hinge head made of metal material, characterized in that the front end of the hinge head is fixedly connected to the frame by heat fusion, and the rear end of the hinge head is hinged to the temples.
[0007] When connecting, the hinge head is heated to a certain temperature, and then the front end of the hinge head is inserted into the set position of the frame, the hinge head melts the frame at this position, so that the front end of the hinge head can be embedded in the frame, and after the melted part of the frame cools down, the frame and the hinge head are fixedly connected. The hinge head and the frame are fixedly connected through the hot melting connection, the fixed connection is high in firmness, the hinge head will not be loose, and thus the stability of the connection between the frame and the leg is improved.
[0008] In the connecting structure of the frame and the leg of the glasses, the front end of the hinge head has at least one fixed rod protruding forward, and the front end of the fixed rod has a barb portion protruding outward from the fixed rod in the up-down and / or left-right direction. The fixed rod is arranged to enable the front end of the hinge head to be deeply inserted into the frame, and the barb portion is covered by the melted plastic when the frame is melted, so that the hinge head is prevented from falling off, the stability of the fixed connection between the hinge head and the frame is further improved, the hinge head will not be loose, and thus the stability of the connection between the frame and the leg is improved.
[0009] In the connecting structure of the frame and the leg of the glasses, the front end surface of the barb portion is arc-shaped. This structure enables the barb portion to better push away the melted plastic, so that the melted plastic can better cover the barb portion and the fixed rod, the stability of the fixed connection between the hinge head and the frame is further improved, the hinge head will not be loose, and thus the stability of the connection between the frame and the leg is improved.
[0010] In the connecting structure of the frame and the leg of the glasses, when the number of the fixed rods is not less than two, a gap is arranged between the adjacent two fixed rods. In this structure, part of the melted plastic can be embedded in the gap during the hot melting connection, the stability of the fixed connection between the hinge head and the frame is further improved, the hinge head will not be loose, and thus the stability of the connection between the frame and the leg is improved.
[0011] In the connecting structure of the frame and the leg of the glasses, the connecting structure further comprises a bow shell and a bow core arranged in the bow shell, the bow shell is inserted and fixed in the front end of the leg, and the rear end of the hinge head is hingedly connected with the front end of the bow core.
[0012] In the connecting structure of the frame and the leg of the glasses, the bow shell is fixedly connected with the leg in close contact, and an anti-skid groove is arranged on the outer side wall of the bow shell and is perpendicular to the front-rear direction of the leg. The bow shell is fixedly connected with the leg in close contact, so that the bow shell and the leg will not be loose, and the anti-skid groove can further improve the firmness of the connection between the bow shell and the leg, so that the bow shell will not fall off, and thus the stability of the connection between the frame and the leg is improved.
[0013] In the connecting structure of the eyeglass frame and the temple of the above-mentioned eyeglass, the elastic arch shell is fixed to the temple by the fastener penetrating through the bottom of the temple and being inserted into the elastic arch shell, and the fastener is located at the rear end of the elastic arch shell. The connecting structure further improves the connection stability of the elastic arch shell and the temple, and the fastener is not exposed, so that the structure of the eyeglass is beautiful.
[0014] In the connecting structure of the eyeglass frame and the temple of the above-mentioned eyeglass, when the temple is opened, the front end of the temple and the rear end of the hinge head are located in the interval. The connecting structure makes the rear end of the hinge head and the front end of the elastic arch shell exposed when the eyeglass is used, and a pattern can be arranged on the front end of the elastic arch shell, so that the structure of the eyeglass is beautiful.
[0015] Compared with the prior art, the connecting structure of the eyeglass frame and the temple of the eyeglass has the following advantages:
[0016] 1. The hinge head of the eyeglass is fixed to the frame by heating the hinge head to a certain temperature and using the hot melt curing method. The connection is firm, the hinge head will not loosen, and the connection stability of the frame and the temple is improved.
[0017] 2. The elastic arch shell of the eyeglass is fixed to the temple by closely fitting, and the elastic arch shell is further fixed to the temple by the fastener. The elastic arch shell and the temple are double-fixed, the firmness of the connection between the elastic arch shell and the temple is improved, and the connection stability of the frame and the temple is improved.
