Fig. 1-6 is please referred to, the utility model provides a kind of technical solution:
A kind of projector for preventing mirror surface dust to be infected with, including projector 1,1 front end face of projector are equipped with projection lens
First 10,1 front end sleeve of projector is equipped with dust cover 2, and wherein one side is equipped with opening to dust cover 2, and is open and 1 shell of projector
Equal in magnitude, the position of 2 another side of dust cover and 10 face of projection lens offers circular hole 20, is embedded with first in circular hole 20
Annulus 21,21 front end of the first annulus are equipped with spiral hood 3, and 3 both ends of spiral hood are equipped with opening, and close to open at one end
It is inside embedded the second annulus 30, is equipped with transparent glass eyeglass 4 at the second annulus 30 in spiral hood 3.
In the present embodiment, 21 outer diameter of the first annulus is adapted with 20 internal diameter of circular hole, and the first annulus 21 is Nian Jie with circular hole 20 solid
It is fixed, it is in order to which the first annulus 21 can be closely bonded with circular hole 20, the first annulus 21 can be held under 3 gravity of spiral hood
By living, and does not fall out, influence leakproofness.
Secondly, 21 outer wall of the first annulus is equipped with external screw thread, 21 width of the first annulus is preferred in 2-4cm, this example
It is 4cm, 20 internal diameter of circular hole is greater than the outer diameter of projection lens 10, and the threaded connection of spiral hood 3 is convenient in externally threaded setting, by
Gradually amplify in the light that projection lens 10 is cast out, therefore 20 internal diameter of circular hole has to be larger than the outer of projection lens 10
Diameter prevents from influencing project effect.
Further, the position on 3 inner wall of spiral hood far from the second annulus 30 is equipped with internal screw thread, and spiral hood
3 internal diameters are adapted with 21 outer diameter of the first annulus, and 3 width of spiral hood is preferably 5cm in 3-5cm, this example, are convenient for spiral shell
Line connection, meanwhile, it needs to place transparent glass eyeglass 4 inside spiral hood 3, needs enough spatial positions.
Specifically, spiral hood 3 is an integral molding structure with the second annulus 30, makes it with more stability, be not easy
It falls.
In addition to this, transparent glass eyeglass 4 is in round pie, and transparent glass eyeglass 4 is with a thickness of 5mm, outside transparent glass eyeglass 4
Diameter is less than 3 internal diameter of spiral hood, and 4 outer diameter of transparent glass eyeglass is greater than the internal diameter of the second annulus 30, facilitates transparent glass mirror
Piece 4 is placed in inside spiral hood 3, and the second annulus 30 stops falling for transparent glass eyeglass 4, meanwhile, transparent glass mirror
The outer diameter of piece 4 is greater than the internal diameter of the first annulus 21.
It is worth noting that transparent glass eyeglass 4 is with a thickness of 5mm, the second annulus 30 with a thickness of 5mm, when spiral shading
When covering 3 perfect threads and being connected on the first annulus 21, the first annulus 21 just presss from both sides transparent glass eyeglass 4 with the second annulus 30
Firmly, the fixation of transparent glass eyeglass 4 is realized.
It should be noted that 2 inside of dust cover is equipped with arc block 22, arc block close to four corners of 20 one side of circular hole
22 are adhesively fixed with 2 inner wall of dust cover, and arc block 22 is damaged to prevent dust cover 2 from being expressed to projection lens 10 when installing
To camera lens, the distance that dust cover 2 is arranged is limited, camera lens and an effect sealed can be protected, mirror surface is prevented to be stained with
Contaminate dust.
It is worth supplement, projector 1 is thrown using the De Baili DP series of Hao scape Science and Technology Ltd., BeiJing SiWei
Shadow instrument model is E-Vision6500-XGA, resolution ratio 1024*768.Transparent glass eyeglass 4 using Nanjing hawk wing light
The optical glass of electric Science and Technology Ltd..
When in use, projector 1 is placed in and needs the projector for preventing mirror surface dust to be infected with of the present embodiment by user
The wisdom classroom to be projected assembles spiral hood 3 and transparent glass eyeglass 4, and is mounted on the first annulus 21, will assemble
Good dust cover 2 is set on projector 1, is begun to use, for a long time after wisdom classroom use, is infected on transparent glass eyeglass 4
After dust, spiral hood 3 is removed into cleaning transparent glass eyeglass 4 or replacement, it is easy to operate, prevent projection mirror surface contamination ash
Dirt.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model
Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical
In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
