Problems solved by technology

[0004] In order to correct the position of the integrating column, an adjustment device is usually provided on the housing of the optical machine, so that the position of the assembled integrating column can be fine-tuned to optimize the image output performance of the optical machine; however, the existing integrating Most of the columns can only achieve vertical height adjustment, and the adjustment dimension is limited, which cannot provide better projection effect

Abstract

The invention provides a convenient-to-adjust integrating column structure for a projector. The convenient-to-adjust integrating column structure for the projector comprises an integrating column bodywith a columnar outer wall; the integrating column body is arranged on the shell of the projector through two supporting pieces; each supporting piece comprises a barrel; a notch is formed in the bottom of the inner wall of each barrel; each notch is semi-annular; two ends of the notch extend to two ends of the corresponding barrel; an elastic piece is arranged in each notch; a supporting plate is fixedly arranged on each elastic piece; each supporting plate is arc-shaped and is matched with the inner wall of the corresponding barrel; a threaded hole is formed in the top of each barrel; threaded rods are arranged at the threaded holes and are used for adjusting the height of the integrating column body; a first gear is fixedly arranged on the outer wall of the integrating column body; a second gear is arranged on one side of the first gear; and a transmission rod is fixedly arranged on the second gear and is used for adjusting the rotation of the integrating column body. The structureof the convenient-to-adjust integrating column structure for the projector is novel. The vertical height of the integrating column can be adjusted; the integrating column can also be rotated; and therefore, the integrating column can be conveniently adjusted to a proper position, and a better projection effect is provided.

Description

technical field [0001] The invention relates to the field of optical path components of projectors, and more particularly, to an integrator column structure for projectors that is easy to adjust. Background technique [0002] The optical machine of the existing projector includes an integrator column, in which the incident light can be totally reflected for multiple times, so that the outgoing light can be uniformly distributed. [0003] In the actual process of assembling the integrating column into the optical-mechanical housing, the actual assembly position of the integrating column is likely to deviate from the original pre-installation due to the manufacturing errors of the integrating column or the optical-mechanical housing itself, as well as the assembly errors generated during assembly. set location. [0004] In order to correct the position of the integrating column, an adjustment device is usually installed on the optical-mechanical housing, so as to use it to fi...
