One end of the base (20) for the temple is provided with a hinge (201) hinged to the lens frame (1), and the other end is provided with an accommodation cavity (202) for accommodating the temple (21). A post (203) is disposed between the opposite sidewalls of the accommodation cavity (202). The changeable temple (21) comprises a pluggable end (210) and an ear end (211). The pluggable end (210) is connected to the ear end (211), and has elastic ends (2101) which are symmetrically arranged at the front portion of a base (2100) for the pluggable end (210), each elastic end (2101) having the shape of "S". Each elastic end (2101) is composed of an extension portion (2102), a middle portion (2102), and an elastic tongue (2104) connected in order, and a space is formed between the two elastic ends (2101). The end of the elastic end (2101) is the elastic tongue (2104), and clamp portions (2105) with downward recesses are disposed in the two opposite elastic tongues (2104), respectively. The post (203) of the accommodation cavity (202) is fitly clamped by the clamp portions (2105), when the pluggable ends (210) of the temples are plugged in the accommodation cavity (202). The spectacle frame has the advantages of simple structure, convenient use, and easy plugging and unplugging.

Description

[Name of invention made by ISA according to Rule 37.2] Pluggable interchangeable glasses frame

Technical field

The utility model relates to a spectacle frame, in particular to a spectacle frame which can be replaced according to requirements of the temple.

Background technique

In the existing spectacle frames, the temples are mostly connected to the edge of the lens frame by a hinge. This type of spectacle frame requires a professional when disassembling or installing, and can be disassembled or installed with professional tools, which is very inconvenient. Recently, there are also frames with interchangeable temples. The connection of the lens frame and the temples provided on both sides is realized by a jig, but the jig includes a hinge piece having a pair of small holes, and the pin passes through the small hole to connect the hinge piece with The corresponding small holes extending from the temple mounting portion of the lens frame are spliced. The hinge piece has a stopper which protrudes from the hinge piece; the frame made of the jig of this structure has a structural complexity problem. The connection between the lens frame and the temple is realized by the plug-and-pull structure. For example, my patent number is “CN200720119984.0”, the name is “plug-in interchangeable leg glasses frame”, the technology solves the complicated structure. The problem, but there is a lack of effort when unplugging.

Summary of the invention

The object of the present invention is to provide a bullet-insertable interchangeable eyeglass frame with simple structure, convenient use, and easy insertion and removal.

The technical solution of the utility model is realized by the following technical solutions: The utility model relates to an inner-elastic plug-in interchangeable eyeglass frame, which comprises a lens frame and a temple provided on both sides, and the lens frame and the temple are plugged and unplugged, and the temple comprises a temple seat and an interchangeable temple. One end of the temple base is provided with a hinge hinged to the lens frame, and the other end is provided with a receiving cavity for receiving the insertion end of the temple, and a buckle column is disposed between the opposite side walls of the receiving cavity; The interchangeable temple includes a temple insertion end and a temple ear hook end. One end of the insertion end of the temple is connected with the end of the temple ear hook, and the other end of the structure is a "S" which is symmetrically extended at the front end of the end seat. The elastic end of the symmetrical design, the elastic end is composed of an extended section, a middle section and a tongue and a tail end, and a spacing is left between each other; at the end of the elastic end is a tongue, and the two opposite tongues are respectively provided with a concave The card position, when the card insertion end is inserted into the accommodating cavity, just catches the gusset provided in the accommodating cavity.

The inner-elastic plug-in interchangeable eyeglass frame has a distance from the two opposite tongues that is smaller than the diameter of the buckle column.

The inner-elastic plug-in interchangeable eyeglass frame has two arcs at opposite ends of the tongue, and two opposite positions are respectively provided with a curvature or inclination for facilitating insertion of the buckle.

The inner elastic plug-in interchangeable leg glasses frame has two opposite ends of the tongue, and at the position of the two opposite ends, in order to enhance the strength of the tongue, respectively, there are protrusions which can resist the middle section.

The inner-elastic plug-in interchangeable eyeglass frame has a cross-section of a square, a rectangle, a circle, and an ellipse; the cross-section of the interchangeable temple is matched with a square and a rectangle. , round, oval.

The inner-elastic plug-in interchangeable eyeglass frame, when the cross-section of the temple base and the interchangeable temple are not the same shape, the two ends of the temple insertion end are inserted into the temple base, and the two connections are The outer surface is a smooth transition surface.

The utility model designs the temple as a temple mounting portion and a replaceable temple portion, and elastically connects the replaceable temple portion with the temple mounting portion by way of plugging and unplugging, so that not only can be easily disassembled The mirror eye realizes the advantage of replacing the temple surface with other temples after the temple is damaged, and has the advantages of simple structure, easy insertion and removal, and convenient use compared with the prior patent technology.
