In figure: attachment base 1, connecting rod 2, shell 3, rotary shaft 4, driving motor 5, first gear 6, second gear 7, connection
Frame 8 connects sleeve 9, sliding slot 10, lead screw 11, screw 12, handle 13, decelerating motor 14.
Specific embodiment
In Fig. 1~2, a kind of suspended scaffold of adjusting pitch angle, including attachment base 1 and setting are in attachment base 1
The connecting rod 2 of bottom, attachment base 1, which is anchored at ceiling or other by bolt, needs position to be mounted, and 2 lower end of connecting rod is equipped with
Luffing mechanism, the luffing mechanism include shell 3, and rotary shaft 4 is equipped in shell 3, and the both ends of rotary shaft 4 are rotated by bearing pacifies
On shell 3, it is equipped with driving motor 5 in shell 3, the output end of driving motor 5 is set with first gear 6, first gear 6 and the
The engagement of two gears 7, second gear 7 are sleeved in rotary shaft 4, and the both ends of rotary shaft 4 are equipped with connection frame 8, connection frame 8 and display
Or projector carries out being bolted realization suspension.
Driving motor 5 drives first gear 6 to rotate, and first gear 6 is engaged with second gear 7 rotates second gear 7, from
And rotary shaft 4 is driven to rotate, rotary shaft 4 drives connection frame 8 to rotate, to realize that the pitch angle of suspended matter is adjusted.
The second gear 7 is sector gear.The swing angle model of hanger is limited by the fan angle of second gear 7
It encloses.
