Abstract
The utility model projector bevel gear type lifting micro-adjusting mechanism, simple in structure, easy to use, reliable operation, laborsaving, projector is indispensable picture output device in modern multimedia meeting room and multi-media classroom, its effect in MultiMedia Field is that image or word are amplified, for people depending on seeing, projector is the transparency of horizontal positioned, by light source, pass through optical device directive level crossing, again by flat mirror reflects to screen, undistorted in order to guarantee figure and the word shape of projection, the light of projection should be vertical with screen, guarantee teaching or effect of meeting.
Description
Technical field
The utility model belongs to micromatic setting technical field, relates to a kind of projector bevel gear type lifting micro-adjusting mechanism.
Background technology
Projector is indispensable picture output device in modern multimedia meeting room and multi-media classroom, and its effect in MultiMedia Field is that image or word are amplified, for people depending on seeing.
Projector principle and projector principle are basic identical, but structure is different, projector is the transparency of horizontal positioned, by light source, pass through optical device directive level crossing, again by flat mirror reflects to screen, undistorted in order to guarantee figure and the word shape of projection, the light of projection should be vertical with screen, otherwise impact teaching or effect of meeting.
Summary of the invention
For overcoming the deficiency of prior art, it is a kind of simple in structure, easy to use that the utility model provides, reliable operation, labour-saving projector lifting micro-adjusting mechanism, and the light of realizing projection should be vertical with screen.
Projector bevel gear type lifting micro-adjusting mechanism, by bevel gear 9, bevel gear 8, spiral 5, spiral 4, guide rod 2,6, projector is placed plate 7, and frame 1 forms.
Bevel gear 9 is connected with axle 10, bevel gear 9 is meshed with bevel gear 8, bevel gear 8 is fixedly connected with spiral 5, spiral 5 forms screw pair with spiral 4, the lower end of guide rod 2,6 forms moving sets with frame 1 respectively, the upper end of guide rod 2,6 is placed plate 7 with projector respectively and is fixedly connected with, and the upper and lower side of spiral 4 and spiral 5 form rotary pair.
Accompanying drawing explanation
Fig. 1 is projector bevel gear type lifting micro-adjusting mechanism front view.
