Lens barrel adjusting structure and 3D glasses device formed by same

Abstract

The invention discloses a lens barrel adjusting structure and a 3D glasses device formed by the same. The lens barrel adjusting structure comprises a fixed support, a left eyepiece and a right eyepiece, wherein the upper ends of the left eyepiece and the right eyepiece are separately connected with transverse adjusting structures for adjusting the left eyepiece and the right eyepiece to move to and fro in the length direction of the fixed support; the left eyepiece and the right eyepiece are arranged below the fixed support at interval and movably connected with the fixed support; each transverse adjusting structure comprises a rotating wheel and a connecting rod which moves to and fro in the length direction of the fixed support, the connecting rod is hinged with an off-axis position of the rotating wheel, the connecting rod and the rotating wheel are respectively connected with the fixed support, and the connecting rod is fixedly connected with the left eyepiece or the right eyepiece. By rotating the rotating wheels of the transverse adjusting structures at the upper part inside the rear end of a shell to drive the connecting rods to rotate, the left eyepiece and the right eyepiece are moved more stably, so that fine adjustment can be realized, and the adjusting precision is higher; and the structure is simple and reliable.

Description

technical field [0001] The invention relates to a 3D glasses device, in particular to a lens barrel adjustment structure and a 3D glasses device k formed by it. Background technique [0002] With the development of science and technology, people have higher and higher requirements for spiritual entertainment, such as entertainment through watching movies, so the quality of movies or TV has attracted more and more attention. Now, people generally choose to watch 3D movies, so 3D glasses are more and more popular. [0003] However, in the current 3D glasses or virtual display glasses products, there is no simple and effective way to adjust the distance between the pupil distance of the glasses (left and right directions) and the distance of the viewing object (front and back directions). There is adjustment in the front and rear directions, but there is no adjustment in the left and right directions. Contents of the invention [0004] The object of the present invention is...
