3D eyeglasses with length adjustable eyeglass racks

Abstract

The invention provides 3D eyeglasses with length adjustable eyeglass racks. The 3D eyeglasses comprise a main body and two eyeglass racks; the main body comprises an eyeglass frame and supporting arms respectively vertically extended from two ends of the eyeglass frame; each eyeglass rack comprises a rack core and a jacket, one end of the rack core is fixedly connected with a supporting arm, and the jacket is sleeved on the outer surface of the rack core; and the rack core is convexly provided with a plurality of limiting strips distributed in the length direction of the rack core, an elastic clamping hook is arranged at one end of the jacket close to one end of the supporting arm, and the elastic clamping hook is clamped between the two adjacent limiting strips. According to the 3D eyeglasses with the length adjustable eyeglass racks, each rack core is provided with the plurality of limiting strips and the jacket is provided with the elastic clamping hook, so that the lengths of the eyeglass racks can be adjusted by adjusting the clamping positions of the elastic clamping hook and the limiting strips.

Description

technical field [0001] The invention relates to glasses, in particular to 3D glasses with adjustable frame length. Background technique [0002] Watching 3D stereoscopic images has become a trend since the release of 3D stereoscopic movies. Currently viewing 3D stereoscopic images still requires wearing exclusive 3D stereoscopic glasses. Generally speaking, when playing such 3D stereoscopic images, the broadcasting industry will provide 3D stereoscopic glasses for viewing for free to the viewers, and they will be recycled for further use after viewing. [0003] However, the frame lengths of these free 3D glasses cannot be adjusted basically, and the industry usually only provides two kinds of glasses with different specifications for use by adults and children respectively. Like this, not only the spectacles manufacturer has to spend more cost to produce the spectacles of different sizes, but also the head shapes of viewers, men, women and children are different in size, a...

[0003] However, the frame lengths of these free 3D glasses cannot be adjusted basically, and the industry usually only provides two glasses with different specifications for use by adults and children

Like this, not only the spectacles manufacturer has to spend more cost to produce the spectacles of different sizes, but also the head shapes of viewers, men, women and children are different in size, and the length of the frame of the glasses of a single size specification is fixed, which cannot be adapted to the wearing of all viewers.

Glasses that cannot adjust the length of the frame are likely to cause instability when wearing, which directly affects the viewing quality of the viewer when using it
