Embodiment
Shown in Fig. 1, be a kind of porjector adjusting device, comprise be arranged on bottom lifting unit 330, be arranged on the angle regulating unit 220 at middle part and be arranged on the rotary unit 110 on top.
Fig. 2 is known, lifting unit 330 comprise be arranged on bottom the first dunnage 1, be arranged on the shearing support 7 at middle part and be arranged on second dunnage 11 on top.In the first dunnage 1, be provided with symmetrical ball screw 2, the two ends of ball screw 2 are fixed in the first dunnage 1 by bearing support 4 respectively.One end of each ball screw 2 is provided with cuts bracket fixing device 3, and the other end is provided with feed screw nut 5.The one side lower end of shearing support 7 is fixed on cuts on bracket fixing device 3, and one side upper end is fixed on litter 10 by the first slide block 82; The opposite side lower end of shearing support 7 is fixed on feed screw nut 5, and its opposite side upper end is fixed on litter 10 by the second slide block 81; Litter 10 two ends are fixed on the bottom position of the second dunnage 11 by litter fixed base 9 respectively; Between two ball screws 2, be provided with synchronous belt mechanism 6.
Lifting unit 330 in the course of the work, rotate handwheel 12, drive ball screw 2 to rotate by handwheel 12, and drive feed screw nut 5 to move left and right along ball screw 2, feed screw nut 5 drives first, second slide block 82,81 inwardly or outwards to slide by shearing support 7.So just can drive lifting unit 330 to rise or decline, in the time reaching suitable lifting position, while stopping operating handwheel, lifting unit automatic locking, what lifting unit can be stable is parked in arbitrary height position.
Known in Fig. 3, angle regulating unit 220 comprises two symmetrical push-rod electric machines 14 that are arranged in the second dunnage 11, and push-rod electric machine 14 upper ends are fixed in the 3rd dunnage 18 by link 15 and universal joint 16 successively; Between two push-rod electric machines 14, be provided with main back shaft 8, main back shaft 8 upper ends are fixed in the 3rd dunnage 18 by joint ball bearing unit 17.
In the time that we need adjusting angle, use a teleswitch (or other control switchs etc.) control any one push-rod electric machine 14 and move, driven the lifting of the 3rd dunnage 18 by push-rod electric machine 14, change the relative angle of the 3rd dunnage 18, thereby realize angle adjustment.Because push-rod electric machine 14 is in uphill process, one side jack-up of the 3rd dunnage 18, under the support of main back shaft 8 and joint ball bearing unit 17, the other end of the 3rd dunnage 18 declines, because projector is placed on this device, so the lifting of dunnage will drive projector to throw in the change of angle.In the time stopping lifting, push-rod electric machine 14 automatically locks and stops.
