Abstract

An embodiment of the present invention provides a lens adjustment device and a projector, the lens adjustment device includes: a lens fixing base, a fixing frame, an elastic connector and at least two adjustment screws with cam-shaped nuts; wherein the elastic connector The lens fixing seat and the fixing frame are pulled closer to each other by elastic force, the adjusting screw is screwed on the fixing frame, and the cam profile surface of the nut of the adjusting screw and the lens fixing seat face toward the fixing One side of the frame is against each other, and the lens holder is pushed to deflect by turning the cam-shaped nut of the adjustment screw. The embodiments of the present invention can reduce the space occupied by the lens adjusting device.

Description

technical field [0001] The invention relates to the lens field, in particular to a lens adjustment device and a projector. Background technique [0002] It is often necessary to adjust the direction of the lens in the optical field where the lens is used. For example, in a projector using a DMD, the direction of the lens needs to be adjusted so that the lens is parallel to the DMD. [0003] figure 1 A schematic diagram of a lens adjustment device in the prior art is shown, the lens adjustment device includes a lens fixing seat 11, a fixing plate 12 and an adjustment screw 14, the lens fixing seat 11 is pressed to the fixing plate 12 by a spring screw 13, and the adjustment The screw 14 is penetrated in the fixing plate 12 to adjust the direction of the lens fixing seat 11, and then realize adjusting the direction of the lens fixedly installed in the lens fixing seat 11, so that the lens is parallel to the DMD15. [0004] figure 1 Although the lens adjustment device shown ...
