Embodiment
See also Fig. 1-Fig. 4, shown in Figure 1 is the synoptic diagram of the projector of first embodiment of the invention; Shown in Figure 2 is the decomposing schematic representation of the projector among Fig. 1; Shown in Figure 3 is synoptic diagram according to camera lens of the present invention; Shown in Figure 4 is the part-structure synoptic diagram of the projector among Fig. 1.The present invention provides a kind of projector 1, comprises camera lens 2, ray machine body 3 and imaging device 4, and ray machine body 3 is arranged between camera lens 2 and the imaging device 4, for example has fixed orifice 42 on the imaging device 4, is locked on the ray machine body 3 through screw or double-screw bolt etc.And projector 1 also comprises adjusting mechanism, and adjusting mechanism comprises at least one first pilot hole 21, at least one first fixed orifice 31, at least one dog screw 22, flexible member 5, first reference column 23, second pilot hole 32 and the 3rd pilot hole 33 and second reference column 9 that intersect vertically.Wherein, first pilot hole 21 is arranged on the camera lens 2; First fixed orifice 31 is arranged on the ray machine body 3, and first fixed orifice 31 is corresponding with first pilot hole 21, and dog screw 22 passes first pilot hole 21 and combines with first fixed orifice 31, and camera lens 2 is positioned between dog screw 22 and the ray machine body 3.Wherein, Preferably, the diameter of first pilot hole 21 is greater than the diameter of dog screw 22, but also not as limit; The diameter of first pilot hole 21 also can equal the diameter of dog screw 22, only need satisfy dog screw 22 and can move relative to first pilot hole 21 and get final product.And preferably, dog screw 22 comprises localization part and threaded portion, and localization part does not have helicitic texture, combines with first pilot hole 21, and threaded portion then screws togather with first fixed orifice 31.
Please continue referring to Fig. 1-Fig. 3, see also Fig. 5 A and Fig. 5 B simultaneously, Fig. 5 A and Fig. 5 B are depicted as the second reference column effect and the synoptic diagram of not doing the time spent of the projector of first embodiment.First reference column 23 is towards ray machine body 3 and be arranged on the camera lens 2, and the end face 24 of first reference column 23 is the inclined-plane.Second pilot hole 32 and the 3rd pilot hole 33 are arranged on the ray machine body 3, and first reference column 23 is inserted in second pilot hole 32; Second reference column 9 combines with the 3rd pilot hole 33, and with 24 effects of the end face of first reference column 23.Do the time spent when second reference column, 9 insertion the 3rd pilot holes 33 and with end face 24, first reference column 23 moves towards the direction away from ray machine body 3, and camera lens 2 is in the first direction R1 swing of initial position court and 32 insertions of second reference column; When second reference column 9 breaks away from end face 24, i.e. second reference column 9 and the end face 24 no effects, first reference column 23 can be got back to original state by the elastic restoring force that flexible member 5 provides, and camera lens 2 is got back to initial position.Thereby the depth of parallelism between camera lens 2 and the ray machine body 2 is adjusted in the interaction that utilizes second reference column 9 and first reference column 23, because imaging device 4 is fixed in ray machine body 2, that is is appreciated that to be the depth of parallelism of adjusting between camera lens 2 and the imaging device 4.
Wherein, second pilot hole 32 and the 3rd pilot hole 33 intersect and are cruciform or T font or L type.
And in this embodiment, second reference column 9 has helicitic texture; The 3rd pilot hole 33 has helicitic texture; Second reference column 9 and the 3rd pilot hole 33 adopt the mode that screws togather to fix, and make second reference column 9 and end face 24 disengaging effects, only need rotation second reference column 9 to get final product; And will not extract the 3rd pilot hole 33 fully by second reference column 9, can avoid losing of second reference column 9.
See also Fig. 6 A-Fig. 7, Fig. 6 A and Fig. 6 B are depicted as the effect of adjustment screw and the synoptic diagram of not doing the time spent of the projector of second embodiment; Shown in Figure 7 is the synoptic diagram of the projector of second embodiment.In this embodiment, the adjusting mechanism of projector 20 also comprises at least one adjustment screw 10; At least one second fixed orifice 25 is positioned on the camera lens 2; And at least one the 3rd fixed orifice 35, being positioned on the ray machine body 3, adjustment screw 10 is locked in second fixed orifice 25 and the 3rd fixed orifice 35 successively.Can swing or translation towards different directions according to the number and the position adjustment camera lens 2 relative ray machine bodies 3 of 10 lockings of adjustment screw.When adjusting mechanism acts on acting force on the camera lens 2 when balanced, camera lens 2 towards or deviate from 3 translations of ray machine body; When adjusting mechanism acts on acting force on the camera lens 2 when unbalanced, camera lens 2 is towards the swing of the position of camera lens 2 stressed maximums.Concrete for example see also Fig. 7, if adjusting mechanism only the position C on ray machine body 3 be provided with the 3rd fixed orifice 35; Correspondence position in camera lens 2 is provided with second fixed orifice 25, and when adjustment screw 10 was locked in second fixed orifice 25 and the 3rd fixed orifice 35, camera lens 2 suffered acting forces were also unbalanced so; Stressed camera lens 2 parts here that make in the position of the position C of camera lens 2 corresponding ray machine bodies 3 can move to ray machine body 3; According to the effect of power, the swing of certain angle can take place towards this position in camera lens 2 so, shown in Fig. 6 B; For example camera lens is swung towards the R1 direction; Thereby can adjust the depth of parallelism between camera lens 2 and the ray machine body 2,, that is be appreciated that to be the depth of parallelism of adjusting between camera lens 2 and the imaging device 4 because imaging device 4 is fixed in ray machine body 2.Again for example; If position A, B, the C of adjusting mechanism on ray machine body 3 is provided with the 3rd fixed orifice 35, and correspondence position A, B, C also are provided with second fixed orifice 25 on the camera lens 2, and three second fixed orifices 25 distribute in going up evenly of camera lens 2; So when adjustment screw 10 is locked in second fixed orifice 25 and the 3rd fixed orifice 35; The suffered acting forces of camera lens 2 are balanced, and so balanced acting force will can not make camera lens swing, and can towards or deviate from 3 translations of ray machine body; And, therefore can adjust the relative distance of camera lens 2 and imaging device 4 by the distance between adjustment camera lens 2 and the ray machine body 3 because imaging device 4 is fixedly arranged on the ray machine body 3.
Certainly, for obtaining the variation of more perspective, can cooperate adjustment screw 10 to use simultaneously with dog screw 22 simultaneously, concrete quantity and position can be decided on demand.
In sum, projector provided by the invention, can be fast the simple depth of parallelism of adjustment camera lens and imaging device, more can adjust relative distance between the two; By this, with focusing quality and the production yield that promotes projector, and reduce the time of doing over again.
