Description
Technical field
The utility model belongs to technical field of optical instrument, relates to a kind of projector prism angle regulating device.
Background technology
The principle of work of existing projector is: the Panel image in inner bare engine module through prismatic reflection, then by projector lens projection imaging.Due to the singularity of light path, the light of Panel image must and camera lens axle center between in vertical angle, its angle tolerance is 90 ° ± 30'', and thus, with position, the setting angle of prism fixedly seems that exception is important.The mounting means of usual prism is stuck on the deck of casing by prism, this mode is because of the forming errors of casing deck or alignment error, cause the angle between the light of Panel image and camera lens axle center cannot ensure in margin tolerance, cause camera lens to project image fog and make bare engine module assemble difficulty.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of easy to adjust and projector's prism angle regulating device of good stability.
For this reason, the utility model adopts following technical scheme:
A kind of projector prism angle regulating device, comprise lens module, described lens module is made up of the optical lens of some coaxial settings, the light end place of described lens module is provided with prism, described prism is total reflection right-angle prism, the plane of light incidence place of described prism is provided with imaging modules, and the beam projecting face of described prism is corresponding with the light end of lens module, and the below place of described prism bases is provided with the casing deck for supporting prism; The bottom surface of described prism is provided with the semisphere revolving part of protrusion, described casing deck is provided with the semispherical indentations suitable with semisphere revolving part, described semisphere revolving part is assemblied in semispherical indentations, and described prism can rotate along the upper surface of the vertical pivot of semisphere revolving part at casing deck.
Further, described semisphere revolving part is positioned at the center of prism bases.
Further, the vertical of described semisphere revolving part highly equals its radius.
Further, described casing deck is made up of plastic cement, and adopting plastic cement to prepare casing deck can effectively avoid prism to wear and tear in adjustment process.
The beneficial effects of the utility model are: under casing deck exists forming errors or error condition appears in projector assemblies installation, prism is carried out Small-angle Rotation along the vertical pivot of semisphere revolving part at the upper surface of casing deck, the angle between the light of projection and optical lens camera lens axle center can be made to ensure in margin tolerance, and the sharpness by observing projected image in adjustment process can determine the optimum apjustment angle of prism, adjustment process is simple and convenient; And the utility model regulating device structural stability is good, and in adjustment process, prism centers can not be subjected to displacement, thus effectively ensure that the quality of projected image.

Embodiment
As Figure 1-4, a kind of projector prism angle regulating device, comprise lens module 1, lens module 1 is made up of the optical lens 2 of some coaxial settings, the light end place of lens module 1 is provided with prism 3, and prism 3 is total reflection right-angle prism, and plane of light incidence 301 place of prism is provided with imaging modules 4, the beam projecting face 302 of prism is corresponding with the light end of lens module 1, and the below place of prism 3 bottom surface is provided with the casing deck 5 for supporting prism 3; The bottom surface of prism 3 is provided with the semisphere revolving part 6 of protrusion, casing deck 5 is provided with the semispherical indentations 7 suitable with semisphere revolving part 6, semisphere revolving part 6 is assemblied in semispherical indentations 7, and prism 3 can rotate along the upper surface of the vertical pivot of semisphere revolving part 6 at casing deck 5; And semisphere revolving part 6 is positioned at the center of prism 3 bottom surface, the vertical of semisphere revolving part 6 highly equals its radius; Casing deck 5 is made up of plastic cement.
During work, the imaging optical path 8 that imaging modules 4 sends is injected by the plane of light incidence 301 of prism and is penetrated by the beam projecting face 302 of prism after prism 3 reflects, then is gone out by the beam projecting end-fire of lens module 1 after lens module 1 transmission.Under normal circumstances, the imaging optical path 8 that prism 3 reflects rear injection should face with the axle center of optical lens 2, but there is error when if casing deck 5 occurs that forming errors or prism etc. are installed, the angle that then prism 3 reflects between the imaging optical path 8 of rear injection and the axle center of optical lens 2 will exceed default tolerance, causes projected image to occur fuzzy.For this reason, need to regulate the setting angle of prism 3.Particularly, prism 3 is carried out low-angle slight rotation along the vertical pivot of semisphere revolving part 6 at the upper surface of casing deck 5, the readability of projected image is constantly observed in rotation process, if the sharpness of projected image reaches best, then stop the angular adjustment of prism 3, now prism 3 reflect the imaging optical path 8 of rear injection be able to be just right with the axle center of optical lens 2.And being positioned at the center of prism 3 bottom surface due to semisphere revolving part 6, in adjustment process, the center of prism 3 can not be subjected to displacement all the time, thus effectively ensure that the quality of projected image.
