Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Understood referring to figs. 1 to Fig. 4：One kind is easy to the adjustable dais step of wheelchair upper-lower height, including ground 1, step
Plate 2 and swash plate 3, the top on the ground 1 be arranged in parallel stepped plate 2, and the left side and right side of the stepped plate 2 are movably hinged swash plate
3, open up the first vallecular cavity 4 on the ground 1, the left side and right side of first vallecular cavity 4 are symmetrical arranged hydraulic stem 5, described in homonymy
The interior boom end of hydraulic stem 5 be fixedly connected with slide plate 6 described in one jointly, the opposite flank of two slide plates 6 is movable
The lower end of connecting rod 7 is connected, the position of the connecting rod 7 and hydraulic stem 5, quantity are corresponding, the upper end flexible connection position of the connecting rod 7
Supporting plate 8 corresponding to putting, the lower end of the supporting plate 8 are flexibly connected with the bottom land of the first vallecular cavity 4, the downside of the stepped plate 2
Face opens up the second vallecular cavity 9, and the both sides of second vallecular cavity 9 open up chute 10, are slidably installed on the chute 10 described in homonymy two pieces
Described sliding block 11, connected by axostylus axostyle 12 between the relative sliding block 11 in position, be slidingly connected sleeve pipe on the axostylus axostyle 12
13, described sleeve pipe 13 is fixedly connected with the upper end of supporting plate described in homonymy 8.
The face that the swash plate 3 is bonded with ground 1 symmetrically opens up groove 14, and the ground 1 symmetrically opens up and the position of groove 14
Corresponding conduit 15, the groove 14 is interior to pass through rotating shaft connection gear 16, and tooth block 17, tooth block 17 and tooth are arranged at intervals in conduit 15
The engagement contact of wheel 16, increases mobile stability；The both ends of the slide plate 6 open up deep-slotted chip breaker 18, and rolling is installed in deep-slotted chip breaker 18
Pearl 19, ball 19 contact with the cell wall of the first vallecular cavity 4, reduce mobile frictional force；The slide plate 6 is between hydraulic stem 5
