Problems solved by technology

[0005] However, due to the figure 1 and figure 2 In the dodging rod adjustment device shown, the light-incident end 041 of the dodging rod is limited by the limit shrapnel 05, and the positioning accuracy of the shrapnel is usually low, and the elastic force is difficult to control. Therefore, after the first adjustment When the screw 06 and the second adjusting screw 07 adjust the position of the light-emitting end of the dodging rod, the light-incoming end 041 of the dodging rod is easy to overcome the elastic force of the limit shrapnel 05 and cause misalignment, so that the overall dodging rod 04 is shifted Or deflection, in this way, the projected picture a of the projector is easy to appear on the screen b as image 3 The deflection shown, which makes it difficult to adjust the position of the dodging rod, and the efficiency is low

Embodiment 1

[0040] Embodiment 1: Both the first adjustment assembly and the second adjustment assembly include two oppositely arranged adjustment screws, the two adjustment screws are respectively arranged on opposite sides of the inner tube, and on the side wall of the outer tube, each adjustment screw corresponds to A threaded through hole is opened at the position, and one end of the adjusting screw is matched and connected in the threaded through hole, and the other end is in contact with the outer wall of the inner tube, so that by simultaneously adjusting the adjusting screws on both sides of the inner tube, the inner tube can be driven to swing in the outer tube .

Embodiment 2

[0041] Embodiment 2: Both the first adjustment assembly and the second adjustment assembly include oppositely arranged adjustment screws and elastic members, the adjustment screws and elastic members are respectively arranged on opposite sides of the inner tube, and on the side wall of the outer tube, the corresponding adjustment screws A threaded through hole is opened at the position, and one end of the adjusting screw is fitly connected in the threaded through hole, and the other end is in contact with the outer wall of the inner tube. The elastic member is used to apply an elastic force to the inner tube to the adjusting screw. screw, the inner tube can be driven to rotate around the first rotation axis l in the outer tube 1 or the second axis of rotation l 2 rotate.

[0042] The second embodiment above can be specifically expressed as: Figure 5As shown, the first adjustment assembly 141 includes a first adjustment screw 1411 and a first elastic member 1412 oppositely a...

Abstract

The invention discloses a dodging rod adjustment device and a projector, and relates to the technical field of projection equipment. The invention is invented to solve the problem that the existing dodging rod adjustment device tends to cause the whole dodging rod to be deflected when adjusting the position of the dodging rod. The dodging rod adjustment device of the present invention includes an outer tube, a rotating ball, an inner tube and an adjustment assembly, the outer tube includes a first end and a second end oppositely arranged, and a spherical housing is formed in the first end of the outer tube Cavity, the rotating ball is hinged in the ball-shaped housing cavity, a through hole is opened on the rotating ball, one end of the inner tube is fixedly connected in the through hole, and the other end is set by the adjustment assembly In the second end of the outer tube, a light beam is transmitted in the inner tube, and the adjustment component is used to drive the inner tube to swing around the center of the rotating ball in the outer tube. The dodging rod adjusting device of the present invention is used in a projector.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a dodging rod adjustment device and a projector. Background technique [0002] In the light source used for projection, the emitted light of the light source is often not uniform enough, and if it is emitted directly, the quality of projection will be affected. Therefore, a dodging device, such as a dodging rod, is usually provided in the projector to evenly light the outgoing light of the light source, and then enter the casing of the imaging component. [0003] In the practical application of the dodging rod, the light incident surface of the dodging rod needs to be aligned with the light exiting surface of the light source, and the light exiting surface of the dodging rod needs to be aligned with the light entrance on the housing of the imaging component. Considering the assembly error , the position of the dodging rod usually deviates from the expected position....
