Embodiment
Now will be in detail with reference to the preferred embodiments of the present invention, embodiment is shown in the drawings, and same reference numerals refers to similar elements in the whole text in the accompanying drawings.For with reference to description of drawings the present invention, described preferred embodiment is described below.
Shown in Fig. 1-3, projector according to a preferred embodiment of the invention comprises: projector main body 2, inner core 4; Be arranged on the optical mode 6 in the inner core 4; And form regulating device 8, described form regulating device 8 at least partly is arranged on the inside of projector main body 2, guide chute 10; Be arranged on the wall of inner core 4, described form regulating device 8 drives described optical mode 6 and in described guide chute 10, moves.When synthetic light projects the projection projection system, image is exaggerated and is projected in (not shown) on the projection screen, and then these assemblies are incorporated in the main body 2.
As shown in Figure 3, move forward and backward in inner core 4 for making things convenient for optical mode 6, also be provided with guidepost 18 on the optical mode 6; This guidepost 18 makes optical mode 6 be connected with form regulating device 8, and promptly guidepost 18 makes optical mode 6 be connected with rotation guide rail 12, when needs are regulated optical mode 6; Only need make and rotate guide rail 12 rotations; Drive guidepost 18 and move, thereby optical mode 6 is moved, reach the effect that form is regulated.
Also be provided with adjusting handle 20 on this form regulating device 8; This adjusting handle 20 is positioned at the front end that rotates guide rail 12; Use this form regulating device 8 for ease of the user; So the relevant position with the use of the adjusting handle 20 of form regulating device 8 on projector main body 2 has opening 22, and this adjusting handle 20 passes this opening 22.This opening 22 is an oblong openings, and after adjusting handle 20 was installed on the main body 2, rectangular opening 22 was the constraint that adjusting handle 20 provides a range of adjustment, i.e. the constraint of form scope.In order to make the projection appearance looks elegant and to prevent that dust from getting in the projector, so be provided with rotation strip 24 in the lower end of adjusting handle 20, the upper surface of this rotation strip 24 is pressed close to the lower surface of main body 2 lids.When needs were regulated form, operating personnel only need adjust handle 20, and adjusting handle 20 drives 12 rotations of rotation guide rail; The gathering sill 16 driving guideposts 18 that rotate in the guide rail 12 move along guide chute 16; Thereby optical mode 6 is moved in inner core 4, reached the effect of adjustment form, in addition, simple in order to assemble; Rotate guide rail 12, rotation strip 24 and adjusting handle 20 and preferably be arranged to Construction integration bodies such as aluminium die casting or moulding resin, as shown in Figure 4.
Explanation is about the amount of movement of projection optical mode 5 at fore-and-aft direction below.Fig. 5 is arranged on the desk projector or on the ground time, the side view of projector projected picture, and the form of projection is bigger than normal; So the user adjusts projected picture, the user adjusts projected picture, and the user adjusts adjusting handle; And adjusting handle 20 drives 12 rotations of rotation guide rail, and rotation guide rail 12 interior ground gathering sills 16 order about guidepost 18 and move along guide chute 10, thereby make optical mode 6 mobile in inner core 4; Thereby the adjusting form is as shown in Figure 6.
Can know by above content; Projection arrangement of the present invention has the very small-sized optical mode travel mechanism of simple structure; Can seek the cost degradation and the miniaturization of device, this projector can also adopt and be hung on the ceiling, is installed in the first-class any method to set up of sidewall in addition, is provided with under the situation any; Do not adopt other method that the form on the screen is adjusted, very easy to use.
As stated, thus the improved structure that the preferred embodiments of the present invention provide a kind of optical mode 6 of easy adjusting projector to regulate the projection form that projects image onto the projector on the screen.
Although illustrated and described the preferred embodiments of the present invention, it will be understood by those skilled in the art that and to make a change in the present embodiment, and do not depart from principle of the present invention and spirit that scope of the present invention is limited appended claims and equivalent thereof.
