Abstract

The utility model discloses inverted folding spectacles which comprise spectacle frames, eyeglasses and arms, the arms are connected with the spectacle frames at two sides of the spectacle frames via hinges, the spectacle frames are connected via a bridging beam, wherein the bridging beam has detachable structure and comprises a left half section and a right half section, the end portion of the left half section is provided with a longitudinal V-shaped gap, the end portion of the right half section is provided with form which is in involution with the gap, a screw is connected with the right half section through a transversal through-hole on the left half section, a back-moving spring is arranged to wrap the screw, a convex edge is positioned in the through-hole. The right and left spectacle frames of the utility model can be mutually turned 180 degrees, thereby the arms can be folded and placed at two sides of the eyeglasses, and the utility model is freely folded or unfolded and quite convenient to be utilized.

Description

The upset folding glasses

Technical field

The utility model relates to a kind of glasses, a kind of more precisely upset folding glasses.

Background technology

The mirror leg of existing various glasses can only folding in a side, can't play the effect of protection minute surface, easily broken when falling accidentally, minute surface also is easy to be worn, in addition, chiasma interference mutually between the mirror leg, using is very much inconvenience.

The utility model content

At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of left and right sides picture frame can rotate 180 degree mutually, thereby can be with the upset folding glasses of mirror leg folding in the eyeglass both sides.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of upset folding glasses, comprise picture frame, eyeglass and mirror leg, mirror leg and picture frame are articulated and connected in both sides, are connected by crossbeam between the picture frame, and described crossbeam is a split-type structural, form for half section by half section on a left side and the right side, the end that a left side is half section has V-notch longitudinally, and right half section end has the shape that is involutory with it, and the cross through hole that a screw rod passes on left half section is connected with right half section, be set with back-moving spring on the screw rod, be provided with the convex edge of support spring in the through hole.

Half section on the left side of described crossbeam is longer, right half section shorter.

Described through hole forms the convex edge of support spring at the inside indentation certain distance of an end near V-notch.

The angle of described V-notch is between 80～120 degree.

The angle of described V-notch is 90 degree.

Described mirror leg is provided with opening elasticity folder backward in its root outside.

The beam design that the utility model will connect left and right sides picture frame becomes the two-part structure; between the two by breach to lumping together; and use screw rod to be connected with spring; left and right sides picture frame can relatively rotate around screw rod, under the effect of spring and V-notch, whenever turns over the just involutory again connection of turnback left and right sides picture frame; like this mirror leg just can folding in the both sides of minute surface; can not only play the effect of protection minute surface, and act freely, use convenience very.

Description of drawings

Fig. 1 is a front schematic view of the present utility model;

Fig. 2 is a schematic top plan view of the present utility model;

Fig. 3 is the schematic top plan view after the utility model upset;

Fig. 4 is the cross-sectional schematic of crossbeam.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---picture frame 2---eyeglass

Half section on 3---mirror leg 4---crossbeam left side

5---right half section 6 of crossbeam---screw rod

7---through hole 8---spring

9---the elasticity folder

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, these glasses are mainly by picture frame 1, eyeglass 2 and mirror leg 3 are formed, mirror leg 3 and picture frame 1 are articulated and connected in both sides, mirror leg 3 is provided with opening elasticity folder 9 backward in its root outside, so that glasses hang up in pocket after packing up, be connected by crossbeam between the picture frame of the left and right sides, this crossbeam is a split-type structural, form for half section 5 by half section 4 long on a left side and the short right side, the end that a left side is half section 4 has V-notch longitudinally, the angle of this breach is 90 degree, right half section 5 end has the shape that is involutory with it, just be equivalent to original whole crossbeam and longitudinally cut into two sections equally along V-notch, this structure mainly is for the ease of the upset location, guarantee the symmetry of left and right sides picture frame, the cross through hole 7 that one screw rod 6 passes on left half section is connected with right half section 5, be set with back-moving spring 8 on the screw rod 6, through hole 7 is at the inside indentation certain distance of an end near V-notch, form the convex edge of support spring 8, just can the inclined-plane by breach cooperate and overcome spring force left and right sides picture frame is relatively rotated as long as apply suitable power during use, and involutory again connection behind moving 180 degree of revolution.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but on its shape or structure, do any variation; every have identical with a utility model or akin technical scheme, all within its protection domain.

Claims

1, a kind of upset folding glasses, comprise picture frame, eyeglass and mirror leg, mirror leg and picture frame are articulated and connected in both sides, are connected by crossbeam between the picture frame, it is characterized in that, described crossbeam is a split-type structural, is made up of for half section half section on a left side and the right side, and the end that a left side is half section has V-notch longitudinally, right half section end has the shape that is involutory with it, the cross through hole that one screw rod passes on left half section is connected with right half section, is set with back-moving spring on the screw rod, is provided with the convex edge of support spring in the through hole.
