Technical Field

The application relates to the technical field of glasses, in particular to a hinged limiting structure for glasses and folding glasses.

Background

Glasses are optical devices worn in front of eyes for improving eyesight, protecting eyes or decorating purposes, and mainly comprise lenses and a frame, and can be divided into myopia glasses, hyperopia glasses, presbyopic glasses, astigmatic glasses and the like according to purposes.

In the related art, chinese patent No. CN206601539U discloses glasses, which comprise lenses, a glasses frame and glasses legs, wherein the lenses are disposed in the glasses frame, the glasses legs comprise a first glasses leg and a second glasses leg, the first glasses leg and the left side of the glasses frame are hinged to a first hinge portion, and the second glasses leg and the right side of the glasses frame are hinged to a second hinge portion. The picture frame includes first picture frame and second picture frame, relies on nose bridge to connect between first picture frame and the second picture frame, and nose bridge middle part is provided with the third hinge portion that supplies first picture frame and second picture frame to rotate, and setting up of third hinge portion makes the picture frame collapsible, has reduced the occupation space when the picture frame is accomodate.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: the nose bridge that is used for connecting first picture frame and second picture frame in above-mentioned glasses does not set up limit structure, and first picture frame and the easy relative rotation of second picture frame when using of glasses lead to the comfort level when glasses are worn to reduce, await the improvement.

SUMMERY OF THE UTILITY MODEL

In order to prevent the relative rotation of the first frame and the second frame when the glasses are worn, the application provides a hinge limiting structure for the glasses and folding glasses.

In a first aspect, the present application provides an articulated limit structure for eyeglasses, which adopts the following technical scheme:

the utility model provides an articulated limit structure for glasses, sets up on the bridge of nose of connecting first picture frame and second picture frame, the bridge of nose is including fixing the first connecting rod on first picture frame and fixing the second connecting rod on the second picture frame, first connecting rod and second connecting rod are articulated, be equipped with the through hole on the first connecting rod, it has the locating part to articulate between the relative both sides wall of through hole, the one end that the second connecting rod is close to first picture frame is equipped with the locating hole that supplies the locating part to change over to, be provided with the spacing breach that supplies second connecting rod tip to pass on the locating part.

Through adopting above-mentioned technical scheme, because first connecting rod and second connecting rod are articulated, can expand first picture frame and second picture frame so that wear when using glasses, can fold first picture frame and second picture frame so that accomodate when not using glasses. When first picture frame and second picture frame expand, the edge of locating part is located the locating hole and can restrict first connecting rod and second connecting rod relative rotation to prevent first picture frame and second picture frame relative rotation, the good, the comfort level of wearing of stability of picture frame is high. If need fold and accomodate first picture frame and second picture frame, then should rotate the locating part so that spacing breach and locating hole align, but first connecting rod and second connecting rod no longer receive blockking of locating part and rotate relatively this moment, but first picture frame and second picture frame rotate relatively in order to realize folding.

Preferably, the limiting part comprises a limiting piece and a push rod which are fixedly connected, the limiting piece is hinged in the through hole, and one end of the push rod exceeds the through hole.

Through adopting above-mentioned technical scheme, when locking or unblock first connecting rod and second connecting rod, the spacing piece of operating personnel accessible exposed push rod drive rotates to realize staggering or the alignment of spacing breach and locating hole, people's hand only need externally control the push rod and need not to extend in the through-hole during the operation, convenient operation. In addition, spacing piece and push rod are fixed connection, and joint strength between them is high, utilizes the push rod to order about spacing piece when rotating both junctions difficult fracture, the long service life of locating part.

Preferably, the limiting sheet is disc-shaped and abuts between two opposite side walls of the positioning hole.

Through adopting above-mentioned technical scheme, when spacing breach and locating hole stagger, if first connecting rod and second connecting rod have relative pivoted trend, then the pore wall of locating hole can produce extrusion stress to spacing piece, and spacing piece is discoid can make its part that is located the locating hole stress everywhere even, avoids spacing piece to produce deformation damage because of local pressurized is too big. And because spacing piece and the lateral wall butt of locating hole, the produced frictional force of contact site between them can be to a certain extent restricted both relative movement to effectively prevent spacing breach and locating hole wrong alignment.

Preferably, the second connecting rod comprises two positioning blocks fixed on one side of the second connecting rod close to the first mirror frame, the positioning hole is formed by the two positioning blocks, and the first connecting rod is provided with a moving groove for the positioning blocks to extend into and the side edge of the moving groove is open.
