Specific embodiment

Below in conjunction with Figure of description embodiment of the present utility model is done detailed description.

As shown in Figure 1, frame 10 of the present utility model is improved and is constructed, and is two outsides at a pair of picture frame 11, is provided with to have the outer two ear framves 20 of opening elasticity and the inside folding of energy, and institute combines.

And for example Fig. 1 and Fig. 2, two picture frames 11 of above-mentioned frame 10 are included between two picture frames 11 and are linked to each other by central sill 12, are respectively equipped with nose pad 13 on the picture frame 11 of central sill 12 bottoms, establish protruding axial region 14 respectively in two picture frames, 11 outsides, are used for engaging lug frame 20.

As Fig. 3, this protruding axial region 14 in above-mentioned picture frame 11 outsides, the axis client that is included in protruding axial region 14 is equipped with axis hole 15; This ear frame 20, what be included in ear frame 20 also is provided with a protruding axial region 21 foremost, and the axis client of protruding axial region 21 is equipped with axis hole 22; Between the two protruding

axial regions

14 and 21, can be by a screw rod 30 coaxial connecting together, and make ear frame 20 be articulated in the outside of picture frame 11.

Fig. 4 is the utility model frame 10 embodiment vertical views.Show among the figure that wherein an ear frame 20 is a folding state.

Fig. 5 is the articulated section bit plane synoptic diagram of the utility model picture frame 11 and ear frame 20.Angle when the ear frame 20 that shows among the figure is unlatching.

Fig. 6 is the articulated section bit plane synoptic diagram of the utility model picture frame 11 and ear frame 20.Angle when the ear frame 20 that shows among the figure is folding.

To shown in Figure 5, the protruding axial region 14 in above-mentioned these picture frame 11 outsides is included on the surface of contact 16 of this protruding axial region 14 and ear frame 20, be provided with 4 grooves 17 with shape, and 17 of each adjacent trenches is an angle of 90 degrees mutually as Fig. 3.

Above-mentioned this ear frame 20 protruding axial region 21 foremost is included on surface of contact 23 correspondence positions of this protruding axial region 21 and picture frame 11, is provided with 4 edge 24; Between two protruding

axial regions

14 and 21, when being connected together by screw rod 30,4 flanges 24 just can be placed on the corresponding surface of contact 16 and become buckling state in 4 grooves 17.

Fig. 3 and for example, above-mentioned this screw rod 30 comprises an elasticity washer 31 and a nut 32.

This elasticity washer 31 just can be placed in the bigger aperture space of picture frame 11 outside axis holes 15 upper end open, and this nut 32 just can be placed in the bigger aperture space of the bottom end opening of ear frame 20 front end axis holes 22; Lock in screw rod 30 ends when nut 32 revolves, when picture frame 11 and ear frame 20 are articulated, utilize this elasticity washer 31, can make between the protruding axial region 21 of the protruding axial region 14 of picture frame 11 and ear frame 20 to have an elasticity nargin.

As Fig. 4, Fig. 5 and Fig. 6, utilize above-mentioned 4 flanges 24 can be fastened on structural design in 4 grooves 17, when ear frame 20 be opening, ear frame 20 is located on the position of opening (90 spend), can not swing arbitrarily.

When rotation ear frame 20 was folding state, each flange 24 can and then rotate, and buckles in next adjacent groove 17, made ear frame 20 to locate on the position of folding (0 degree), can not open arbitrarily.

When the user rotates 20 unlatchings of ear frame or folding,, make unlatching or folding operation also there is no hell and high water because elasticity washer 31 provides the elasticity nargin between the two protruding

axial regions

14,21.

Therefore, aforesaid the utility model, pivot joint position between eye glass frame and two ear framves, design can make two ear framves can be on the position of folding and unlatching the structure of strong fix, the ear frame of unlatching can not swung arbitrarily, the ear frame of folding can not opened arbitrarily, better use effect is provided, promote glasses serviceable life, reached predetermined purpose of the present utility model.
