The quick-change glasses leg of this application design can be quick, the glasses leg of different functions of accurate change, easy operation is convenient. The structure integrates a common spring structure in the spectacles industry, and can provide comfortable wearing.

Examples

As shown in fig. 1 to 4, a quick-change glasses leg with an elastic structure comprises a glasses leg 2 and a connecting piece 3, wherein a glasses leg front groove 21 and a glasses leg rear groove 22 are arranged on the inner side of the connecting end of the glasses leg 2; the connecting piece 3 comprises a slingshot hinge 31 connected to a bottom plate 32, and a rear foot 33 and a front foot 34 are also arranged on the bottom plate 32; the rear foot 33 is in clamping connection with the rear groove 22 of the glasses leg, and the front foot 34 is in clamping connection with the front groove 21 of the glasses leg; the slingshot hinge 31 is also hinged with the front hinge 4 on the front frame 1.

The utility model provides a mirror leg is articulated through catapult hinge and preceding hinge, can realize rotation between them, pack up and open the mirror leg that can be convenient, owing to set up the catapult hinge, open the process and open the back at the mirror leg, can receive inwards pulling force always, can not appear the phenomenon that the mirror leg is loose after wearing, has guaranteed the travelling comfort of wearing.

In the application, the connection end of the glasses leg 2 refers to one end of the glasses leg 2 close to the front frame 1, and a glasses leg front groove 21 and a glasses leg rear groove 22 are arranged on the inner side of the connection end of the glasses leg 2, so as to ensure the adaptation with the connecting piece 3. The slingshot hinge 31 is a conventional slingshot hinge, and is internally provided with a spring, and when the glasses legs are unfolded, the spring is elastically pulled, so that the glasses legs are tightened to the side close to the front frame.

The quick-change glasses leg mainly comprises two parts, namely a metal connecting piece 3 and a glasses leg 2.

The metal connector 3 is a core component of the whole structure, and is made of a metal material, and white copper or beryllium copper materials are generally adopted in the spectacles industry. The slingshot hinge 31 is a common structure in the spectacles industry, and is internally provided with a spring structure which is matched with the front hinge 4, so that elastic connection can be realized, and a wearer can feel comfortable. The bottom plate 32 of the connector 3 may be manufactured by a metal stamping process or a metal casting process, and combined with the slingshot hinge 31 by a welding process to form a whole (see fig. 4). The rear leg 33 and the front leg 34 are round, so that the disassembly is convenient.

The glasses leg 2 is made of plastic generally, and has good extrusion deformation performance by adopting injection molding. The front groove 21 of the glasses leg adopts a structure with a small upper part and a big lower part to be matched with the front foot 34 of the metal fitting (see figure 3).

The specific connection operation mode of the connecting piece 3 and the glasses leg 2, the front hinge 4 is as follows:

the rear leg 33 of the metal fitting is inserted from below the rear groove 22 of the glasses leg, and the rear groove 22 of the glasses leg is in an open structure and is a round hole, so that half of the rear leg 33 is inserted into the round hole and can rotate inside, and the other half is exposed outside. Such a design is to facilitate the disassembly and assembly of the metal connector 3. After the metal fitting rear foot 33 is inserted, it is rotated forward, and the front foot 34 is engaged with the temple front groove 21. This completes the assembly of the metal connector 3 and the temple 2 in a single moving unit (see fig. 2).

The slingshot hinge 31 on the metal connecting piece 3 is connected with the front hinge 4 on the front frame 1 through a screw, so that the slingshot hinge 31 and the front hinge 4 can rotate around the screw, and the opening and closing of the glasses leg 2 are realized, and the spring force participates in the opening and closing process (see figure 1).

When the glasses legs are replaced, the front feet 34 of the metal connecting pieces 3 can be pulled out of the glasses leg grooves 21 with little force, the glasses legs are rotated to a certain position, the rear feet 33 of the metal connecting pieces 3 are pulled out of the glasses leg rear grooves 22, and therefore the separation of the metal connecting pieces 3 and the glasses legs 2 is completed, and the glasses leg replacement operation (see fig. 2) can be achieved.

In the specific embodiment, a common plastic temple 2 is prepared, on which a temple front groove 21 and a temple rear groove 22 have been machined (see fig. 3). The connecting piece 3 has been screwed with the front hinge 4.

The temple channel 22 is slid over the rear leg 33 from the opening and then rotated to push the front leg 34 into the temple channel 21, indicating that the assembly is in place when a clear catch sound is perceived, at which time the glasses may be used normally (see fig. 1).

When it is desired to disassemble, the rear half of the temple 2 is held and the thumb is rotated outwardly against the slingshot hinge 31 to disengage the front foot 34 from the temple front channel 21 (see fig. 2) and then the rear foot 33 is removed from the temple rear channel 22. Thus, the disassembly work of the glasses legs is completed.

The operation is repeated in the actual operation, so that the glasses legs with different functions can be replaced simply and quickly. Different glasses legs can be designed according to the needs, such as glasses legs with three functions: one is a common plastic temple for use in a common environment; one is a sports temple for sports scenes; one is an anti-lost temple (built-in circuit board) for a scene where the glasses are easy to forget. The three glasses legs can be replaced at will, and a user can replace the glasses legs according to different use environments, so that the user can use the glasses more conveniently.
