Technical field
The utility model relates to a kind of projector.
Background technology
Projector claims again projector, is a kind ofly image or video to be projected to the equipment on curtain, can be by different interfaces same computing machine, VCD, DVD, BD, game machine, DV etc. be connected and play corresponding vision signal.Officemate office partner projector is widely used in family, office, school and public place of entertainment, according to working method difference, has CRT, LCD, and DLP etc. are dissimilar.
Projector focus mechanism has three kinds of electrostatic focusing, magnetic focusing and electromagnetism complex focusings, wherein comparatively advanced with electromagnetism complex focusing, its advantage is good condensing performance, especially under high brightness conditions, can defocus, and focusing accuracy is high, can carry out subregion focusing, edge focusing, four angular focusing, thus can accomplish that on picture, every bit is all very clear.Above-mentioned focusing is that the light path system of projector is arranged substantially, also has the camera lens of pair projector that focus adjusting mechanism is set at present, but focusing process lens are not very stable, easily shake, and lens reset and also can not accomplish fast, stablize playback.
Utility model content
In view of this, the utility model provides a kind of projector, and it overcomes the lens shake drawback in focusing process, and can make quick, the stable playback of lens in camera lens.
The utility model is achieved in that a kind of projector, and it comprises shell, be housed in the light path system in this shell and be arranged on this side wall of outer shell and be positioned at the focusing lens in the light path of this light path system; These focusing lens comprise lens barrel, two installing rings, two lens, drive unit, elastic component, these two lens are coaxial being arranged on these two installing rings respectively, these two installing rings are screwed on respectively in this lens barrel, these two lens and this lens barrel are coaxial, and this drive unit drives the optical axis spiral movement of these two installing rings along this lens barrel; This elastic component is located between these two installing rings, and the two ends of this elastic component are separately fixed on these two installing rings, and this elastic component is annular flexure strip and coaxial with this lens barrel in the time not there is deformation, and this elastic component is occurring when elastic deformation in the shape of a spiral.
As the further improvement of such scheme, these focusing lens are fastened on this side wall of outer shell by least one buckle.
As the further improvement of such scheme, be fixed in this lens barrel near the installing ring of this light path system, this drive unit only drives the spiral movement of optical axis along this lens barrel away from the installing ring of this light path system.
As the further improvement of such scheme, the two ends of this elastic component are positioned on the straight line perpendicular to this lens barrel optical axis.
Projector of the present utility model, focusing lens are in the time of focusing, drive unit drive installation ring is along the spiral movement of optical axis of lens barrel, installing ring drives respective lens to move and realizes focusing, in focusing process, elastic component generation elastic deformation produces stress, and elastic component can spiral elongates follows installing ring and move, overcome the lens shake drawbacks (overcoming the indirect shake producing by installing ring) in focusing process, and in the time that lens reset, can make quick, the stable playback of lens.
Brief description of the drawings
The structural representation of the camera lens of the projector that Fig. 1 provides for the utility model preferred embodiments.
Fig. 2 is the schematic top plan view of throwing the elastic component of camera lens in Fig. 1.
Main symbol description: focusing lens 1, lens barrel 2, installing ring 3, lens 4, elastic component 5.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, the projector that the utility model preferred embodiments provides comprises shell (not shown), be housed in the light path system (not shown) in this shell and be arranged on this side wall of outer shell and be positioned at the focusing lens 1 in the light path of this light path system.Focusing lens can be fastened on this side wall of outer shell by least one buckle, in the time not needing to use focusing lens 1, can remove at any time or change other camera lenses like this, are user-friendly to.
These focusing lens 1 comprise lens barrel 2, two installing rings 3, two lens 4, drive unit (not shown) and elastic components 5.These two lens 4 are coaxial being arranged on these two installing rings 3 respectively, these two installing rings 3 are screwed on respectively in this lens barrel 2, these two lens 4 are coaxial with this lens barrel 2, and this drive unit drives the optical axis spiral movement of these two installing rings 3 along this lens barrel 2, thereby realizes the focusing of lens 4.Drive unit can drive two installing rings 3 move simultaneously (as, two installing rings 3 oppositely move), also can only drive one of them installing ring 3 to move, as in the present embodiment, be fixed in this lens barrel 2 near the installing ring 3 of this light path system, this drive unit only drives the spiral movement of optical axis along this lens barrel 2 away from the installing ring 3 of this light path system.
Incorporated by reference to Fig. 2, elastic component 5 is located between these two installing rings 3, the two ends of this elastic component 5 are separately fixed on these two installing rings 3, and this elastic component 5 is annular flexure strip and coaxial with this lens barrel 2 in the time not there is deformation, and this elastic component 5 is occurring when elastic deformation in the shape of a spiral.Focusing lens 1 are in the time of focusing, drive unit drives the spiral movement of optical axis along this lens barrel 2 away from the installing ring 3 of this light path system, the respective lens 4 that drives installing ring 3 moves and realizes focusing, in focusing process, there is elastic deformation and produce stress in elastic component 5, elastic component 5 can spiral elongates follows installing ring 3 and moves, and the lens 4 that overcome in focusing process are shaken drawback (overcoming the indirect shake producing by installing ring 3), and in the time that lens 4 reset, can make lens 4 fast, stable playback.The two ends of this elastic component 5 can be positioned on the straight line perpendicular to these lens barrel 2 optical axises, can centered by the optical axis of lens barrel 2, realize rotational symmetry up and down like this, thus uniform force application.Certainly the deformation power of elastic component 5 has certain limit, but it is enough to tackle the lens focusing of projector, need to improve but will meet general camera lens.
