The lens is quite convenient to change without disassembling a box of the projector, and all actions are externally completed.
Description
Technical field
The present invention relates to a kind of dustproof construction, a kind of dust guard of more particularly, to projector motion camera lens.
Background technology
Image is thrown into screen by camera lens by projector, for enabling image to project to suitable position, it usually needs adjust
The position of projected picture；When projector places on the table, most common method is exactly the height by adjusting lower margin, thus
Change the position of camera lens and angle to realize；The method that there has also been motorized adjustment camera lens in the market, makes camera lens level, vertically
Motion, this method is easy to adjust and image moving range is also bigger, and meanwhile, projector is possible to configure several camera lenses, enters
And changed according to use environment.
Exactly because the motility of this camera lens and convertibility, current technology makes the dust-proof realization of this part especially multiple
Miscellaneous, and dust-proof extremely important to this optical apparatus of projector, and dust enters from the gap of machine from the external world, can affect projected light
Intensity, the radiating of machine, thus damaging the quality of machine, reduce service life of a machine.
The dust control technology of current motion camera lens mainly passes through to use sponge wrapping camera lens in camera lens surrounding, make sponge and
Camera lens gapless, the other end of sponge and cabinet are also that gapless fits together, and to stop the entrance of extraneous dust；And in mirror
Head surrounding using sponge wrapping camera lens come blocks dust entrance existing method in, when camera lens moves up and down it is possible to
So that sponge and camera lens is fitted not tight, produce gap and allow dust to enter；And, when changing camera lens, need to take cabinet apart,
In cabinet inside, by camera lens and sponge again fits together so that guest operation is very inconvenient.
Content of the invention
The technical problem to be solved is to need to provide one kind not only to make camera lens good dustproof effect, and changes
The dust guard of camera lens very easily projector's motion camera lens.
In this regard, the present invention provides a kind of dust guard of projector motion camera lens, comprising: camera lens, projector, dustcloth group
Part, drawstring and rope tensioning block；Described camera lens and dustcloth assembly are arranged in projector；One end of described drawstring and dustcloth group
Part is connected, and the folding of dustcloth assembly can be controlled to facilitate taking-up or installation camera lens by pulling of drawstring；Described drawstring
