Working principle

Upper berth: when the left hand piston bar of dual Piston hydraulic cylinder 9 moves downward, the upper end plank of upper layer bed board is on upper berth Under leading portion connecting rod pushes, the hinge between upper end plank and intermediate plank is rotated up, and tilts upper end plank, formation is leaned on Back.When the right hand piston bar of dual Piston hydraulic cylinder 9 moves downward, the lower end plank of upper layer bed board 7 end link behind upper berth Under pulling, the hinge between lower end plank and intermediate plank is rotated down, and transfers the lower end plank of upper layer bed board 7, shape At pedal.When dual Piston hydraulic cylinder piston is in initial position, the same plank position of 3 block size of left, center, right of upper layer bed board In same plane, plate is slept in formation.

Lower berth: by swinging handle 14, the rotation of powered belt dynamic bevel gear 17 drives roller gear 13 by bevel gear 17 Mobile in rack position, driving lower end plank moves downward, and stacks intermediate plank and upper end plank, forms backrest.Instead To swinging handle, it is generally aligned in the same plane 3 pieces of upper, middle and lower plank, plate is slept in formation.

Two-berth attachment device: by screw rod swinging handle 16, the rotation of helical screw 15 is made to drive nut to move to drive It is dynamic.When the distance between two nuts 3 of same control device reduce, when doing movement close to each other, upper berth moves up and down machine Structure is elongated to be got higher, and upper berth rises.When the distance between two nuts 3 of same control device become larger, the movement being located remotely from each other is done When, upper berth reciprocating mechanism shorten it is short, upper berth decline.

The foregoing is merely preferred embodiments of the invention, rather than the limitation to the present invention in any form.This field Technical staff can impose various equivalent changes and improvement on the basis of the above embodiments, all to be done within the scope of the claims Equivalent variations and modification, should all fall under the scope of the present invention.
