Set 10 thickness direction size.Speculum 500 is set in babinet 100, what speculum 500 was used to launch on camera lens 320
Light reflexes on projection screen 200, therefore shows image information on projection screen 200.
Also referring to Fig. 4 and Fig. 5, adjustment frame assembly 400 is set in babinet 100, and lighting apparatus component 300 is set to adjustment
On frame component 400, adjustment frame assembly 400 is used to adjust the position of lighting apparatus component 300.Specifically, adjustment frame assembly 400 includes the
One adjustment plate 410, fixed plate 420, the first adjusting rod 430, the first adjusting nut 440, second adjustment plate 450, the second adjusting rod
460 and second adjusting nut.
Specifically, the first adjustment plate 410, fixed plate 420, the first adjusting rod 430 and the first adjusting nut 440 are for adjusting
Lighting apparatus component 300 moves horizontally in left-right direction relative to babinet 100, to adjust the image information on projection screen 200 along left
Right direction moves horizontally.Second adjustment plate 450, the second adjusting rod 460 and the second adjusting nut are for adjusting 300 phase of lighting apparatus component
Babinet 100 is vertically moved, is zoomed in and out with adjusting the image information on projection screen 200.Wherein, left and right directions
Refer to when user faces projection screen 200, the left and right directions of user, vertical direction is absolute vertical direction.
The first adjustment plate 410 is movably arranged at along perpendicular to the thickness direction of babinet 100 on babinet 100, fixed plate
420 are fixed on babinet 100, and the first adjusting rod 430 is arranged in fixed plate 420, and one end offsets with the first adjustment plate 410,
First adjusting nut, 440 spiral shell is set to the other end of the first adjusting rod 430.
Referring to Fig. 5, for example, when turning the first adjusting nut 440 clockwise, the first adjustment plate 410 can be made relative to case
Body 100 moves right, and the image information on projection screen 200 is accordingly past to move right.Turn the first adjusting nut 440 counterclockwise
When, the first adjustment plate 410 can be made to be moved to the left relative to babinet 100, the image information on projection screen 200 is accordingly past to move to left
It is dynamic.
Second adjustment plate 450 is set to movably in a vertical direction on the first adjustment plate 410, and the second adjusting rod 460 is worn
On second adjustment plate 450 and one end is fixed on the first adjustment plate 410, and the second adjusting nut spiral shell is set to the second adjusting rod
460 other end.
For example, when turning the second adjusting nut clockwise, second adjustment plate 450 can be made to close to the first adjustment plate 410
Direction moves down, and the image information on projection screen 200 is amplified.When turning the second adjusting nut counterclockwise, second can be made
Adjustment plate 450 is moved up to the direction far from the first adjustment plate 410, and the image information on projection screen 200 is reduced.
Specific in present embodiment, the quantity of the second adjusting rod 460 and the second adjusting nut is respectively four, four
Two adjusting rods 460 are located at four corners of second adjustment plate 450, and one second adjusting nut corresponds to one second adjusting rod 460 respectively.
Four the second adjusting nuts are respectively nut C, nut D, nut E and nut F (as shown in Figure 5).
If adjusting any two in tetra- nuts of C, D, E, F simultaneously, different results is obtained.For example, instantaneous simultaneously
Needle adjusting nut C and nut E, then the left side of image information be amplified.Conversely, adjusting nut C and nut E counterclockwise simultaneously, then
The left side of image information is reduced.Adjusting nut D and nut F clockwise simultaneously, then be amplified on the right of image information.Conversely,
Adjusting nut D and nut F counterclockwise simultaneously, then the right of image information is reduced.
For example, instantaneous needle adjusting nut C and nut D simultaneously, then the top of image information is amplified.Conversely, inverse time simultaneously
Needle adjusting nut C and nut D, then the top of image information is reduced.Simultaneously clockwise adjusting nut E and nut F, then image believe
The lower part of breath is amplified.Conversely, adjusting nut E and nut F counterclockwise simultaneously, then the lower part of image information is reduced.
Referring to Fig. 2 and Fig. 4, DLP shows that projection arrangement 10 further includes air-guiding aisle 700, and air-guiding aisle 700 is used for
It is connected in babinet 100 with outside babinet 100, DLP display projection dresses can be conducive to toward the cold air outside the interior importing of babinet 100
The heat dissipation inside 10 babinet 100 is set, and then extends the service life that DLP shows projection arrangement 10.
Above-mentioned DLP shows that projection arrangement 10 has at least the following advantages：
Lighting apparatus component 300 is set in babinet 100, and lighting apparatus component 300 includes optical machine main body 310 and camera lens 320, speculum
500 are set in babinet 100, and speculum 500 is used to the light launched by camera lens 320 reflexing to projection screen 200.By
In the substantially L-type camera lens 320 of camera lens 320, therefore camera lens 320 reduces in the size of the thickness direction of babinet 100, and then can subtract
Small entire DLP shows the thickness of projection arrangement 10, so saving space.Adjustment frame assembly 400 is for adjusting lighting apparatus component 300
Vertically left-right and front-back orientation moves, and to adjust the position of lighting apparatus component 300, and then adjusts and reflexes to 200 upper figure of projection screen
As the orientation and size of information.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
