Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1 to Figure 3, a kind of projection device car, comprise the base plate 10 of cuboid, on each drift angle of base plate 10, be all rotationally connected the adjuster bar 20 of adjustable in length, the end of each adjuster bar 20 is rotationally connected the back up pad 30 for the cuboid of support projection machine, in the present invention, the length of back up pad 30 and width are less than respectively length and the width of base plate 10, connect back up pad 30 and be skewed with the adjuster bar 20 of base plate 10, regulate the length of each adjuster bar 20 and vergence direction and angle of inclination with the angle degree adjustable support plate 30 of base plate 10.Base plate 10 in the present invention can be placed the relevant device supporting with projector, and as computer, DVD etc., projector is placed on vergence direction and tilts in the back up pad 30 that can regulate arbitrarily, according to requirements, regulates vergence direction and the angle of back up pad 30.
Concrete, adjuster bar 20 comprises head rod 21 and socket second connecting link 22 in the inner of hollow, and head rod 21 is provided with the second connecting link 22 locking knob 23 on head rod 21 that locks.So, can regulate arbitrarily the length of described adjuster bar 20, simple in structure, easy to operate.
Preferably, one end of the head rod of each adjuster bar 20 21 is rotatably connected on base plate 10 by spherical swivel 40, one end of the second connecting link 22 of each adjuster bar 20 is also rotationally connected to back up pad 30 by spherical swivel 40, spherical swivel 40 comprises the first component 41 with ball-shaped end 42, and can entangle ball-shaped end 42 and adeciduate second component 44.Concrete, first component 41 comprises the threaded rod 43 being connected in ball-shaped end 42, second component 44 comprises the bell and spigot joint that can entangle ball-shaped end 42 45 of recessed circle and is connected to the connecting portion 46 of adjuster bar 20 ends.Utilize the bell and spigot joint 45 of recessed circle to entangle ball-shaped end 42, and ball-shaped end 42 can not come off in bell and spigot joint 45, can make relative ball-shaped end 42 universal rotationals of bell and spigot joint 45.When installation, on each drift angle of base plate 10 and back up pad 30, be all connected first component 41, and the first component 41 on base plate 10 arranges in opposite directions with the first component 41 in back up pad 30, and the threaded rod on first component 41 43 is locked in base plate 10 and back up pad 30; Two ends at adjuster bar 20 all connect second component 44, be connected on the one end of the head rod 21 on base plate 10 and connect second component 44, be connected to liquid on the one end of the second connecting link 22 in back up pad 30 and connect second component 44, the connecting portion of second component 44 46 is locked on head rod 21 and the second connecting link 22 ends, more each bell and spigot joint 45 is entangled respectively to each ball-shaped end 42.When use, under original state, the height of four adjuster bars 20 is consistent, and back up pad 30 is parallel to each other with base plate 10, in the time regulating wherein the length of certain adjuster bar 20, the length of other three adjuster bars 20 remains unchanged, because each adjuster bar 20 can rotate by any direction, back up pad 30 is also rotatably connected on the end of each adjuster bar 20, when the height change of one of them adjuster bar 20, the angle between all the other adjuster bars 20 and base plate 10 also correspondingly changes, thereby drive back up pad 30 run-off the straights, around this principle, if make back up pad 30 reach needed vergence direction and angle of inclination, regulate the length of each adjuster bar 20, change the angle degree of each adjuster bar 20 and base plate 10.
Further, the back up pad 30 in the present invention is provided with the fixed orifice 31 of fixing projector, and the surrounding edge 32 that prevents projector's landing is set on the periphery of back up pad 30.Projector is placed in back up pad 30, on the shell of general projector, has threaded hole, the fixed orifice 31 that utilizes screw that projector shell is locked in back up pad 30 can prevent in the time that back up pad 30 tilts, and projector rocks and affects use; Surrounding edge is set and can further avoids projector to drop from back up pad 30, guarantee the use safety of projector.
Move for convenience of projection device car of the present invention, can on base plate 10, connect roller 11, be movable to needed position, then roller 11 is pinned.
The beneficial effect of projection device car of the present invention is:
1, by base plate and back up pad are set, can place respectively projector and with the supporting equipment of projector, easy to use, between base plate and back up pad, be rotationally connected the adjuster bar of adjustable in length, by regulating the length of each adjuster bar, to change the angle of each adjuster bar and base plate, the height of adjustable support plate on the one hand, the vergence direction of adjustable support plate and angle of inclination on the other hand, meets user of service's various demands;
2, base plate, back up pad and adjuster bar be rotationally connected simple in structure, convenient operation;
3, fixed orifice and surrounding edge are set in back up pad, guarantee the use safety of projector.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on instructions, must determine technical scope according to claim scope.
