Main element symbol description

The present invention that the following detailed description will be further explained with reference to the above drawings.

Specific embodiment

Referring to Fig. 1, in a better embodiment of the invention, a kind of projector 100 includes that a casing 10, one is accommodated in Ray machine mould group 40 and one in the casing 10 are fixed on the projective module group 70 on the casing 10.

The casing 10 includes a pedestal 20 and one is detachably fixed to upper cover 30 on the pedestal 20.The pedestal 20 surround an accommodating space 35 with the upper cover 30 jointly, and the ray machine mould group 40 and the projective module group 70 are housed in described In accommodating space 35.The pedestal 20 includes that a bottom plate 21, one is vertically connected on the foreboard 22, one of 21 front end of bottom plate vertically The back plate 23 and two for being connected to 21 rear end of bottom plate are respectively perpendicular the side plate 24 for being connected to 21 two sides of bottom plate.The ray machine Mould group 40 is fixedly mounted on the bottom plate 21, and the bottom plate 21 is equipped with several positioning columns 211, and the upper cover 30 is inserted into It is fixed on the pedestal 20 in the positioning column 211.The foreboard 22 is equipped with a mounting hole 221, the projective module group 70 are mounted in the mounting hole 221.The back plate is equipped with several interfaces 231, and the interface 231 is set to connect outside It is standby.The foreboard 22 and the side plate 24 are equipped with several ventilation holes 25, and the ventilation hole 25 is to facilitate the projector 100 Heat dissipation.

Please see Fig. 2 to Fig. 4, the ray machine mould group 40 includes that an ontology 50 and one can cover the lid closed on the ontology 50 Component 60.Described 50 one end of ontology is equipped with one first recessed portion 51, and the lid component 60 is equipped with one and first recessed portion 51 Corresponding second recessed portion 61, first recessed portion 51 surround a recessed portion 41, institute with second recessed portion 61 jointly Recessed portion 41 is stated to accommodate a light emitting device (not shown).The ontology 50 is additionally provided at first recessed portion 51 One through-hole 52, the through-hole 52 is to allow the light of the light emitting device transmitting to pass through.

The ontology 50 is additionally provided with one first light guide portion 53 at the through-hole 52, and the lid component 60 is equipped with one and institute Corresponding second light guide portion 63 of the first light guide portion 53 is stated, first light guide portion 53 is collectively formed with second light guide portion 63 One photoconductive tube 43.It include several eyeglass (not shown) in the photoconductive tube 43, the eyeglass is to reflect or be refracted into institute State the light in photoconductive tube 43.In one embodiment, the eyeglass includes but is not limited to reflecting mirror and lens, wherein the reflection Mirror makes the light ray parallel advance to reflection light, and the lens are to refracted light with magnified image.The ontology is close A perforation 54 is additionally provided at first light guide portion 53, it is described to perforate 54 to facilitate light to pass through.

50 other end of ontology is additionally provided with a holding part 55, and the holding part 55 is a hollow cavity, the projection Mould group 70 can accommodate in the cavity.Described 55 one end of holding part is additionally provided with an opening 551, and the projective module group 70 can Across the opening 551.
