Referring to fig. 3 and 4, the front leg 41 includes a hinge 411 hinged to the pile head 3, and an extension 412 fixed to a side of the hinge 411 away from the pile head 3, wherein the extension 412 is integrally formed on the hinge 411 and is formed by bending the hinge 411 to the upper side, so that when the temple 4 rotates around its hinge end with the pile head 3, the extension 412 can rotate to the upper side of the lens 1. In other embodiments, the extension 412 may also be formed by bending the hinge 411 downward, so that when the temple 4 is rotated around its hinged end with the pile head 3, the extension 412 can be rotated to the lower side of the lens 1.

Referring to fig. 3 and 5, the rear leg portion 42 includes a connecting portion 421 and an anti-falling portion 422 integrally formed on the connecting portion 421, the anti-falling portion 422 is located on a side of the connecting portion 421 away from the front leg portion 41, and one end of the anti-falling portion 422 away from the connecting portion 421 extends downward to block the forward movement of the temple 4 hung above the ear of a person.

Referring to fig. 1 and 5, in order to increase the anti-slip property of the temples 4 and reduce the damage of the temples 4 to the ears of a person, a protective sleeve 6 made of an elastic material is sleeved outside the anti-slip part 422, and the protective sleeve 6 in this embodiment is made of a rubber material. Set up the anticreep groove 61 that supplies anticreep portion 422 card to go into on lag 6, when anticreep portion 422 stretched into anticreep groove 61, lag 6 all formed smooth transition with the top surface, the bottom surface of connecting portion 421, and temple 4 surfacing.

Referring to fig. 5 and 6, the front leg 41 and the rear leg 42 are hinged by a first hinge 7, and the first hinge 7 includes a first hinge block 71 fixed inside the extension part 412, a second hinge block 72 fixed inside the connecting part 421, and a rotating shaft 73 inserted into the first hinge block 71 and the second hinge block 72. In the present embodiment, the first hinge block 71 is fixed to the extending portion 412 by riveting, and the second hinge block 72 is fixed to the connecting portion 421 by riveting, in other embodiments, the first hinge block 71 and the second hinge block 72 may also be fixed by welding or gluing.

Referring to fig. 5 and 6, the middle portion of the first hinge block 71 is provided with an abdicating groove 711 for the end of the second hinge block 72 to extend into. The top surface of the first hinge block 71 is provided with a counter bore 712 communicated with the receding groove 711, the lower side groove wall of the receding groove 711 is provided with a threaded hole 713 coaxial with the counter bore 712, and the second hinge block 72 is provided with a second hinge hole 721. When the second hinge block 72 is inserted into the offset groove 711, the counterbore 712, the second hinge hole 721 and the screw hole 713 are aligned.

Referring to fig. 5 and 6, the shaft 73 in this embodiment includes a hinge bolt having a head portion received in the counterbore 712 and a shank portion connected to the threaded bore 713. In other embodiments, the first hinge block 71 may be provided with a light hole, and the second hinge block 72 may be provided with a screw hole, so that the hinge bolt is screwed with the second hinge block 72; or the hinge bolt is separately connected with a nut, and screw holes are not formed in the first hinge block 71 and the second hinge block 72.

Referring to fig. 1 and 2, when stored, the rear leg 42 is rotated inward relative to the front leg 41 about the rotary shaft 73, so that the entire length of the temple 4 can be reduced. When the pile is used, the rear leg 42 is rotated to the maximum angle, even if the connecting portion 421 and the extending portion 412 are at 180 °, the extending portion 412 abuts against the side of the connecting portion 421 facing the pile head 3, so as to prevent the connecting portion 421 from rotating further.

Referring to fig. 1 and 2, the hinge 411 and the pile head 3 are hinged to each other through the second hinge 8, and the structure of the second hinge 8 in this embodiment is substantially the same as that of the first hinge 7, and only the form of the first hinge block 71 and the second hinge block 72 is changed. So arranged, the temple 4 can be turned about the second hinge 8 to achieve further folding of the spectacles. In other embodiments, the second hinge 8 may be provided with other hinge structures, any structure that can realize the relative rotation between the temple 4 and the pile head 3 may be adopted.

In other embodiments, the hinge portion 411 may be connected to the upper side of the pile head 3, that is, a limit post is disposed below the hinge portion 411, a limit groove into which the limit post is inserted is formed in the upper end surface of the pile head 3, and the limit post and the pile head 3 can rotate relative to each other when the limit post extends into the limit groove, so that the hinge portion 411 and the pile head 3 can be hinged. So set up, as long as set up spacing post long enough, can make mirror leg 4 rotate to directly over lens 1 when folding, and need not to set up mirror leg 4 into the structure of following vertical buckling.

Referring to fig. 3 and 4, in order to reduce interference of the glasses legs 4 on folding of the glasses, concave arc sections 43 are respectively arranged at the lower ends of the extension part 412 and the connecting part 421, the bottom surfaces of the concave arc sections 43 are matched with the top surface of the lens 1 in shape, and the vertical distance from the bottom surface of the concave arc section 43 to the second hinge part 8 is greater than the vertical distance from the top surface of the glasses frame 5 to the second hinge part 8. In other embodiments, the concave arc section 43 may be provided at the upper end of the temple bar 4 to correspond to the temple bar 4 being folded to the lower side of the lens 1.

Referring to fig. 1 and 2, the nose bridge 2 includes two connecting rods 21 hinged to each other, the two connecting rods 21 are hinged by a third hinge 9, and the structure of the third hinge 9 in this embodiment is substantially the same as that of the first hinge 7, and similarly, only the form of the first hinge block 71 and the second hinge block 72 is changed. After the third hinge 9 is assembled in place, the two links 21 can be rotated in the direction of approaching the temple 4 and both can only maintain the opening angle of 180 ° at the maximum. That is, when the folded glasses are unfolded, the two links 21 can only be rotated forward to be parallel to each other, and at this time, the close ends of the two links 21 abut against each other to prevent the two links from further rotating forward.

Referring to fig. 7, a nose pad 22 is disposed below each connecting rod 21, the nose pad 22 includes a hard rod 221 fixed on the lower side of the connecting rod 21, and an elastic sleeve 222 sleeved on the outer side of the hard rod 221, and the top end of the hard rod 221 is fixed on the connecting rod 21, and the bottom end of the hard rod extends obliquely to the adjacent lens 1, so that the elastic sleeve 222 is not easily separated from the hard rod 221. In this embodiment, the material of the hard rod 221 is the same as that of the temple 4, and the material of the elastic sheath 222 is rubber, but in other embodiments, the hard rod 221 and the elastic sheath 222 may be made of other materials.

The implementation principle of the folding glasses in the embodiment of the application is as follows: when the glasses are stored, the rear legs 42 are rotated inwards around the first hinge parts 7 to fold the glasses legs 4; then the folded temple 4 is rotated towards the lens 1 around the second hinge 8, so that the temple 4 is rotated above the lens 1; then the nose bridge 2 rotates around the third hinge 9 in opposite directions, so that the glasses can be folded and stored. The thickness and the occupation space of folding back glasses are little, conveniently accomodate and carry.

It should be noted that, in the process of folding the glasses, if the temple 4 collides with the frame 5 or the pile head 3, since the material of the temple 4 is resin, the operator can break the temple 4 to make it deform adaptively, so as to reduce the interference of the temple 4 on the folding of the glasses.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
