Description

glasses frame

technical field

The utility model relates to a spectacle frame, in particular to a spectacle frame with high safety and long service life.

Background technique

Spectacle frames generally include two frame parts, and there is a bridge part between the two frame parts. In order to facilitate loading and unloading of spectacle lenses, each frame part has an upper edge frame and a lower edge frame. A picture frame screw is screwed to assemble the upper and lower edge frames; two nose pads are located on the inner side of the second picture frame; and two mirror feet are respectively located on the relative outer sides of the second picture frame.

When the user accidentally hits them severely, these protruding nose pads or their brackets that cannot be disengaged in time will be harmful to the user. The nose or eyes of the user will be directly injured; meanwhile, the glasses lenses will also cause damage to the user's face.

(2) When the nose pads or their brackets are damaged, these nose pads and their brackets cannot be replaced individually, but the entire set of spectacle frames needs to be replaced.

(3) The mating surfaces of the upper frame and the lower frame of the mirror frame are planar mating, which also causes a plane deviation, and the firmness of the combination is not good.

(4) The internal thread used for combination is directly tapped on the frame body of the upper frame and the lower frame of the frame. Once the internal thread is damaged, it will damage the frame and cause the frame to be unusable. , and the entire set of glasses frames must be replaced.

(5) When the temples are welded to the outer side of the frame, when the temples are damaged, the whole set of spectacle frames must be replaced; The combination of points, its combination is not strong, and it is easy to loosen and fall off.

Detailed ways

The aforementioned and other technical contents, features and functions of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings.

Referring to Fig. 1 to Fig. 6, it is a preferred embodiment of the spectacle frame of the present invention. The spectacle frame includes a frame unit 1 , a nose pad unit 2 , and a temple unit 3 .

The frame unit 1 has a bridge portion 11 and two frame portions 12 respectively connected to the left and right sides of the bridge portion. The inner space of the two frame portions 12 is used for assembling spectacle lenses (not shown). A continuous embedding groove 13 is recessed on the adjacent surfaces of the mirror bridge part 11 and the two mirror frame parts 12 .

The nose pad unit 2 has an elastic frame body 21 and two nose pad pieces 22 respectively assembled at two ends of the elastic frame body. In practice, a clamping opening 211 is formed at both ends of the elastic frame body 21, and a convex groove body 221 is embedded in the nose pad piece 22, and the nose pad piece is clamped on the clamping opening 211 with its convex groove body 221. No need to use any screws, very convenient to assemble.

The shape of the main body of the elastic frame body 21 matches the shape of the insertion groove 13 and can be embedded in the insertion groove 13 . That is to say, the nose pad unit 2 and the mirror frame unit 11 maintain a temporary fitting relationship, not a permanent and firm combination relationship. In addition, in assembly, a notch 14 is respectively provided on the inner surface of the two mirror frame parts 12 relative to the inner part, and each notch communicates with the slot 13, so that a part of the two ends of the elastic frame body 21 can pass through each notch 14 respectively, and to The rear surface of each mirror frame portion extends.

The mirror leg unit 3 has two mirror leg parts 31 , and the two mirror leg parts are respectively assembled on the opposite outer parts of the second mirror frame part 12 using sleeve nuts 33 for wearing on the two ears of the user.

When the user wears the spectacle frame of the present utility model, when a serious collision occurs accidentally, the elastic frame body 21 of the nose pad unit 2 will be squeezed and stretched elastically, and from the socket 13 of the frame unit 1 Falling off inside, thus preventing the protruding nose pad 22 and its frame body 21 from causing damage to the user's nose or eyes. Simultaneously, because the falling off of the nose pad unit 2 also causes the loose state between the spectacle frame unit 1 and the user's face, it is easy to fall off from the user's face, thereby also avoiding the possible damage of the spectacle lens to the user's face. Therefore, the spectacle frame of the utility model has extremely high safety in use.

In addition, when the nose pads 22 or their elastic frames 21 are damaged, it is only necessary to replace these nose pads and their frames individually, that is, only the nose pad unit 2 needs to be replaced without replacing the whole set of spectacle frames.

For the convenience of loading and unloading spectacle lenses, the two frame parts 12 each have an upper edge frame 121 and a lower edge frame 122. The lower frame is screwed together. Wherein, these matching surfaces are not plane matching surfaces, for example, the matching surface of the upper frame 121 is a V-shaped groove 123, and the matching surface of the lower frame 122 is a V-shaped convex body 124, thereby preventing the upper , and the plane offset after the lower edge frame is aligned, and has good combination firmness.

Furthermore, the lower edge frame 122 is vertically pierced with a through hole 125, while the upper edge frame 121 is horizontally pierced with an embedding hole 126, and has a stud 127 embedded in the embedding hole, and the stud is provided with a screw hole 128. Frame screws 15 pass through the perforation 125 of the lower edge frame 122 and are screwed with the studs 127 of the upper edge frame 121. That is to say, the frame part 12 is combined with the additionally formed stud 127 , and when the thread of the screw hole 128 of the stud 127 is damaged, only the stud 127 needs to be replaced instead of the whole set of spectacle frames.

In addition, except that the two temple parts 31 are assembled on the outer side of the second mirror frame part 12 with a temple screw 32 and sleeve nut 33 respectively, at the same time, the outer parts of the two temple parts 31 are respectively provided with a notch 16, and The temple portion 31 is provided with a protrusion 311 corresponding to the notch 16 and capable of being accommodated in the notch. According to this structure, when the mirror foot unit 3 is accidentally damaged, only the mirror foot unit 3 needs to be replaced without replacing the entire set of spectacle frames; The positioning and firm locking of the mirror foot screw 32 and the sleeve nut 33 make the mirror foot unit 3 and the mirror frame unit 1 have a good combination firmness.

To sum up the above, since the nose pad unit and the frame unit of the spectacle frame of the present invention are a temporary combined structure, when a collision occurs accidentally, the nose pad unit can be separated from the frame unit, which has good safety in use; The upper frame and the lower frame adopt non-planar alignment, which can prevent the plane deviation of the upper and lower frames; achieve the combination of the upper and lower frames with another formed stud, when the stud is damaged, only need It is enough to replace the stud alone without damaging the service life of the whole set of spectacle frames; the mirror leg unit is assembled in the frame unit with a structure of screw combination, convex post resisting and sleeve nut positioning and locking, which has the convenience of replacement and combination Advantages of firmness.

Although the utility model has described the above-mentioned preferred embodiments in detail, the above-mentioned ones are only preferred embodiments of the utility model and cannot be limited thereto. The scope of implementation of the utility model, that is, all simple equivalent changes and modifications made according to the patent application scope of the utility model and the description of the utility model, all still belong to the scope covered by the utility model patent.
