In one embodiment of this invention, at each fastening of ray machine housing 1 and lens bracket 2, ray machine housing 1
Offered on corresponding wallboard (such as the side wall 6 of 4/ bottom wall of roof 8/) through the wallboard and open-ended first chute 19, first
Chute 19 could be arranged to various shapes, for example：Rectangle is could be arranged to, it can also be provided that the splicing of semicircle and rectangle
Shape together, it can also be provided that shape of semiellipse etc..Corresponding wallboard (such as bottom wall 9/ of roof 5/ of lens bracket 2
Side wall 7) internal offer the second chute for offering through the wallboard and being connected with the cavity 20 on cavity 20, and the wallboard
21, cavity 20 could be arranged to arbitrary shape, but must ensure that the inside of cavity 20 is in contact with corresponding sheet regulating part 11
Inner surface be close to the outer surface of the sheet-shaped regulation part 11, to ensure that the sheet-shaped regulation part 11 is plugged in inside the cavity 20
Afterwards, the cavity 20 can be driven integrally to be moved along the direction perpendicular to both contact surfaces, wherein preferably a kind of set-up mode
For：The shape that cavity 20 is set to completely agree with corresponding sheet regulating part 11, for example, by sheet-shaped regulation part 11 and cavity 20
Cuboid is disposed as, is coated on as what the cuboid of cavity 20 agreed with as the rectangular external of sheet-shaped regulation part 11, this
Sample, sheet-shaped regulation part 11 is plugged in behind the inside of cavity 20, and the entirety agreed with completely is formed with cavity 20, can be as overall
One motion, is greatly enhanced the degree of regulation of the lens adjustment device.Corresponding sheet regulating part 11 is plugged in inside cavity 20
Afterwards, corresponding adjusting screw 10 is through second chute 21 and the tapped through hole 12 of corresponding sheet regulating part 11, its locating slot 13
With the clamping of the first chute 19, it is specially：Locating slot 13 is connected in after the first chute 19, two cell walls up and down of locating slot 13
Connect with the respective wall board of the both sides of the first chute 19.The shape of second chute 21 is it can also be provided that a variety of, for example, can set
For rectangle, it can also be provided that two ends are semicircle, centre is rectangular shape, can also in order to reduce sliding friction
Second chute 21 is set to ellipse.Lens bracket 2 is relative along vertical direction together under the drive of sheet-shaped regulation part 11
When light engine moves up and down, the adjusting screw 10 at both ray machine housing 1 and lens bracket 2 side wall fastenings can be along phase
Answer the second chute 21 to slide up and down, will not rotate, so as to avoid at this sheet-shaped regulation part 11 relative to the adjusting screw
10 are subjected to displacement, and then eliminate lens bracket 2 relative to light engine while the linkage for moving up and down and moving left and right
Effect.Similarly, lens bracket 2 is transported along horizontal direction relative to light engine or so together under the drive of sheet-shaped regulation part 11
When dynamic, the adjusting screw 10 at ray machine housing 1 and both roofs of lens bracket 2 and/or bottom wall fastening can be along corresponding second
Chute 21 horizontally slips, and will not rotate, and occurs so as to avoid sheet-shaped regulation part 11 at this relative to the adjusting screw 10
Displacement, and then eliminate the connected effect that lens bracket 2 is moved left and right and moved up and down relative to light engine.Thus,
In specific set, glide direction is mutually perpendicular to glide direction in the second chute 21 in the first chute 19, if for example, first
Chute 19 is half elliptic, and the second chute 21 is ellipse, then, the major axis of the long axis direction of the first chute 19 and the second chute 21
Direction is mutually perpendicular to.
In the specific implementation, in order to simplify the structure of the lens adjustment device, the generally bottom wall of roof 4/ in ray machine housing 1
8 and side wall 6 on open up first chute 19, it is accordingly, also equal on the bottom wall 9 of roof 5/ and side wall 7 of lens bracket 2
Open up second chute 21 and the cavity 20 being connected with second chute 21.If it is intended to making the knot of the lens adjustment device
Structure is simpler, when specifically setting the lens adjustment device in itself and camera lens being adjusted using the lens adjustment device, behaviour
Make simpler convenience, only can open up one first respectively on the roof 4 or bottom wall 8 and side side wall 6 of ray machine housing 1
The second chute 21 and cavity 20 on chute 19, lens bracket 2 do relative set with reference to ray machine housing 1.For example, in ray machine housing
First chute 19 is respectively opened up on 1 roof 4 and side side wall 6, accordingly, in the roof 5 and side side wall of lens bracket 2
Second chute 21 and the cavity 20 connected with second chute 21 are respectively opened up on 7；Or, in the He of bottom wall 8 of ray machine housing 1
First chute 19 is respectively opened up on side side wall 6, accordingly, is respectively opened up on the roof 5 and side side wall 7 of lens bracket 2
One the second chute 21 and the cavity 20 being connected with second chute 21.
First chute 19 can be arranged at the optional position of the corresponding wallboard of ray machine housing 1, in order to improve camera adjusting dress
First chute 19, is generally arranged at the centre position of the corresponding wallboard of ray machine housing 1 by the degree of regulation put, for example, by ray machine shell
The first chute 19 on the bottom wall 8 of 1 roof of body 4/ be arranged at the equidistant centre position of two side wall 6, by ray machine housing 1
The first chute 19 on side wall 6 is arranged at and its roof 4 and the equidistant centre position of bottom wall 8.Accordingly, by the second chute
21 are arranged at the centre position of the corresponding wallboard of lens bracket 2, and specific setting refers to the setting of ray machine housing 1, no longer detailed herein
State.
Lens adjustment device 100 provided in an embodiment of the present invention, because ray machine housing 1 and lens bracket 2 are snapped together,
And at each fastening, the locating slot 13 of adjusting screw 10 is connected on the corresponding wallboard of ray machine housing 1, such as adjusting screw
10 locating slot 13 is connected in the first chute 19 being arranged on the corresponding wallboard of ray machine housing 1, and its of the adjusting screw 10
Corresponding wallboard (second chute 21 that is for example arranged at the corresponding wallboard of lens bracket 2) and phase of its position through lens bracket 2
The tapped through hole 12 of sheet-shaped regulation part 11 is answered, and the screw thread of the tapped through hole 12 and the screw thread of the adjusting screw 10 are engaged, and are made
Obtain when tightening or unclamping adjusting screw 10, clamped condition is kept between adjusting screw 10 and ray machine housing 1, will not produce relative
Displacement, so that the rotation of adjusting screw 10 drives to tapped through hole 12 by the mutual cooperation of screw thread so that sheet-shaped regulation part 11
Along horizontal direction relative to the corresponding side-to-side movement of adjusting screw 10 or along vertical direction relative in corresponding adjusting screw 10
Lower motion, so as to drive lens bracket 2 together along horizontal direction relative to (light engine) side-to-side movement of ray machine housing 1 or edge
Vertical direction to move up and down relative to ray machine housing 1 (light engine), realize to deviation between light engine and camera lens 17
Adjustment.
Using foregoing lens adjustment device 100 between the camera lens 17 of projector and the DMD 15 of light engine
Deviation when being adjusted, if the screw thread in the screw thread of adjusting screw 10 or the tapped through hole 12 of sheet-shaped regulation part 11 is ground
There are certain minor deviations in the screw thread of damage, or both, in specific regulation, lens adjustment device itself may occur partially
Turn, i.e. lens bracket 2 when moving together with sheet-shaped regulation part 11, and lens adjustment device itself occurs to turn along its center axis
Dynamic, the distance that the left and right sides or upper and lower ends for causing lens bracket 2 are moved is different, produces deviation, so as to cause regulation essence
Degree is inaccurate.
