Abstract
The present invention relates to a kind of reflective dust-proof projector, it includes housing, it is provided with luminous source in described housing, it is provided with dmd chip in described luminous source side, being arranged over reflecting mirror at described dmd chip, described housing includes protecgulum and illuminator lid, is provided with reflecting mirror installing port on described illuminator lid, described reflecting mirror is located at inside reflecting mirror installing port, is provided with dust protection rubber circle at described reflecting mirror and illuminator lid junction.Present configuration is simple, good dustproof effect, is greatly improved product service life.
Description
Technical field
The present invention relates to a kind of projection arrangement, be specifically related to a kind of opaque projector.
Background technology
Reflection-type projector itself possesses the advantage of its uniqueness, just can project in the shortest distance
Go out the picture of bigger picture, eliminate a lot of spaces.But due to convex surface and the illuminator of plane
Must exposed outside, add that nonspherical reflector and aspheric lens are all that aspheric surface causes and adds
Work difficulty is very big, will necessarily there is trickle mismachining tolerance, and illuminator needs in phase after installing
Doing trickle adjustment on the tool answered, this has also resulted in and can leave one between illuminator and shell
Fixed gap, and be unfixed, the machine that current market is similar to the most does not processes this gap,
So dust will be entered inside machine by this gap, of long duration can affect making of complete machine
Use the life-span.
Summary of the invention
Goal of the invention: the invention aims to overcome deficiency of the prior art, it is provided that one
Plant simple in construction, good dustproof effect, be greatly improved the reflective dust-proof projection in product service life
Machine.
Technical scheme: in order to solve above-mentioned technical problem, one of the present invention is reflective anti-
Dirt scialyscope, it includes housing, is provided with luminous source in described housing, at described luminous source one
Side is provided with dmd chip, is arranged over reflecting mirror at described dmd chip, before described housing includes
Lid and illuminator lid, be provided with reflecting mirror installing port on described illuminator lid, and described reflecting mirror sets
Inside reflecting mirror installing port, it is provided with dust protection rubber at described reflecting mirror and illuminator lid junction
Circle.
Described reflecting mirror is convex reflecting mirror or plane mirror.
Described dust protection rubber circle is bonded to one with illuminator lid.
Described dust protection rubber circle is bipeltate circle.
The material of described dust protection rubber circle is bipeltate, and it has elastic big, low excellent of price
Gesture, compares with common foam, has light resistance good, high temperature resistant and be difficult to the advantages such as aging.Dress
First use gum to be assembled into an assembly on dust protection rubber circle and illuminator lid when of joining, refill
It is fitted on complete machine, uses the mode that this assembles, can be the most attractive in appearance but also be rapidly performed by the group of complete machine
Dress.
Beneficial effect: compared with prior art, its remarkable advantage is the present invention: the present invention is overall
Simple in construction, uses dmd chip, makes projection definition high, uses convex reflecting mirror,
Areas imaging is relatively big, uses foaming dust protection rubber circle, can effectively seal and block reflecting mirror with anti-
The gap of light microscopic lid junction, prevents dust from entering inside machine, thus improves product and use the longevity
Life, described dust protection rubber circle is bonded to one with illuminator lid, the most attractive in appearance but can Fast Installation,
Meet actual operation requirements.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of the present invention；
Fig. 2 is the mounting structure plan view of heretofore described dust protection rubber circle；
Fig. 3 is the mounting structure side view of heretofore described dust protection rubber circle.
Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the reflective dust-proof projector of one of the present invention,
It includes housing 1, is provided with luminous source 2 in described housing 1, in described luminous source 2 side
It is provided with dmd chip 3, is arranged over reflecting mirror 4, described housing 1 at described dmd chip 3
Including protecgulum 5 and illuminator lid 6, described illuminator lid 6 is provided with reflecting mirror installing port 7,
Described reflecting mirror 4 is located at inside reflecting mirror installing port 7, at described reflecting mirror 4 and illuminator lid
6 junctions are provided with dust protection rubber circle 8；Described reflecting mirror 4 is convex reflecting mirror or plane reflection
Mirror；Described dust protection rubber circle 8 is bonded to one with illuminator lid 6；Described dust protection rubber circle 8
For bipeltate circle.Overall structure of the present invention is simple, uses dmd chip, makes projection clear
Clear degree height, uses convex reflecting mirror, and areas imaging is relatively big, uses foaming dust protection rubber circle, can
Block reflecting mirror and the gap of illuminator lid junction with effective sealing, prevent dust from entering machine
Inside, thus improve product service life, described dust protection rubber circle and illuminator lid are bonded to one
Body, the most attractive in appearance but also can Fast Installation, meet actual operation requirements.
The invention provides a kind of thinking and method, implement method and the way of this technical scheme
Footpath is a lot, and the above is only the preferred embodiment of the present invention, it is noted that for this skill
For the those of ordinary skill in art field, under the premise without departing from the principles of the invention, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention,
Each ingredient the clearest and the most definite in the present embodiment all can use prior art to be realized.
