Fig. 1 is one-piece construction front elevation of the present invention.

Fig. 2 is one-piece construction vertical view of the present invention.

Fig. 3 is the structural representation of drive division of the present invention.

Embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, for learning the mechanical book of mechanical principle, bound by display page and form, the first display page 2 is provided with sick bed mechanical model, and the second display page 1 is provided with the drive link 11 for affecting sick bed mechanical model to launch;

Described drive link 11 comprises the first drive link 111 and the second drive link 112 of proximal hinge, and the distal end articulated of described first drive link 111 is on the second display page 1, and far-end and the sick bed mechanical model of described second drive link 112 are hinged;

Described sick bed mechanical model comprises sick bed 3 and the drive division 4 for driving the bed board 32 of sick bed 3 to turn down;

Described sick bed 3 comprises bedstead 31, four footposts 311 of described bedstead 31 are hinged on the first display page 2, near two footposts 311 of the second display page 1 and the distal end articulated of the second drive link 112, described bed board 32 comprises back plate 321, buttocks plate 322, thigh plate 323 and the calf plate 324 that axle successively connects, described buttocks plate 322 is fixed on bedstead 31, rotating shaft 3221 crossbearer at described buttocks plate 322 two ends is on bedstead 31, and two of described bedstead 31 is equipped with the fagging 312 of the free end of free end for supporting back plate 321 and calf plate 324;

The drive division 4 be positioned at below bed board 32 comprises bottom and is hinged on fixed head 41 on the first display page 2, the both sides in described fixed head 41 front are hinged with for the first rocking bar 43 of jack-up back plate 321 with for second rocking bar 42 of jack-up thigh plate 323 with calf plate 324 junction, the described free end of the first rocking bar 43 and the lower surface of back plate 321 are conflicted, free end and the thigh plate 323 of described second rocking bar 42 are conflicted with the lower surface of calf plate 324 junction, the link of described first rocking bar 43 and the second rocking bar 42 is all hinged with connecting link 45, the other end of described connecting link 45 is hinged with the two ends of crank 44 respectively, the handle 441 driving described crank 44 to rotate is arranged on the back side of fixed head 41.

When need close the first display page 2 and the second display page 1 time, was fallen in the direction of sick bed 3 towards the second display page 1, then the fixed head 41 of drive division 4 was fallen, finally the second display page 1 was closed.

When opening the second display page 1, the footpost 311 of bedstead 31 is stood under the traction of drive link 11, and sick bed mechanical model is unfolded, and manually erects drive division 4, can carry out next step operation.

With hand fixed handle 441, crank 44 rotates thereupon, under the drive of connecting link 45, the first rocking bar 43 and the second rocking bar 42 rotate thereupon, and the first rocking bar 43 and the second rocking bar 42 one high and one low, when the first rocking bar 43 is raised, first rocking bar 43 jack-up back plate 321, when the second rocking bar 42 is raised, the second rocking bar 42 thigh plate 323 and calf plate 324 junction, by controlling the rotation direction of crank 44, bed board 32 can be made as required to should be position turnover mutually.

When back plate 321 and calf plate 324 are not dug, both free ends all support by the fagging 312 at bedstead 31 two, thus keep whole bed board 32 steady.

Content described in this instructions embodiment is only enumerating the way of realization of inventive concept; should not being regarded as of protection scope of the present invention is only limitted to the concrete form that embodiment is stated, protection scope of the present invention also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
