The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the wide wheel chair folding mechanism of the adjustable bed rearrangement of this utility model has the left front vertical tube 101 of wheelchair frame, right front vertical tube 102, left back vertical tube 103 and right back vertical tube 104, and above-mentioned 4 vertical tubes constitute the main supporting tubular member of seats.The jackknife action of fold mechanism is finished together by above-mentioned 4 vertical tubes of left and right rectangle pipe 1,2 drivings of mutually hinged one-tenth " X " shape, above-mentioned left rectangle pipe 1 is by left oriented tube 3 and left front vertical tube 101 interlocks, and right rectangle pipe 2 is by right oriented tube 4 and right front vertical tube 102 interlocks.
Above-mentioned left rectangle pipe 1 has upper left pipe 11 and lower-left pipe 13, connect by two parallel left connection tubes between the upper and lower pipe in a left side, right rectangle pipe 2 upper right pipes 11 and bottom right pipe 13, connect by two parallel right connection tubes between the right upper and lower pipe, left and right rectangle pipe is rotationally connected by hinged realization " X " shape between two left and right connection tubes.
Above-mentioned left oriented tube 3 is " fourth " font, and its transverse tube part one end inserts in the upper left pipe 11 of left rectangle pipe 1, and the vertical tube of left oriented tube partly inserts in the left front vertical tube 101 of wheelchair frame; Right oriented tube 4 also is " fourth " font, and its transverse tube part one end inserts in the upper right pipe 21 of right rectangle pipe 2, and the vertical tube of right oriented tube partly inserts in the right front vertical tube 102 of wheelchair frame.The lower-left pipe 13 of left side rectangle pipe 1 is between the forward and backward vertical tube 102,104 in the right side, pipe two ends, lower-left are respectively equipped with union joint 131, union joint has the arcuate groove 131-1 that cooperates with right forward and backward vertical tube, and the bottom right pipe 23 of same right rectangle pipe also cooperates with the forward and backward vertical tube 101,103 in a left side.
See to be respectively equipped with on the above-mentioned left and right down pipe 13,23 of Fig. 6, Fig. 7, Fig. 8 and Fig. 9 that locking mechanism 6 is used for and the front and back vertical tube cooperates the locking relative position, locking mechanism has lock housing 61, poke rod 62, locking bar 63 and spring 64.With the locking mechanism on the lower-left pipe 13 is example, lock housing 61 is fixed on pipe middle part, lower-left, poke rod 62 has two branches to be listed in the lock housing both sides, locking bar 63 also has two, all be positioned at lower-left pipe pipe, locking bar one end is fixedlyed connected with poke rod, the other end has dead bolt 63-1, stretch to the union joint 131 at pipe two ends, lower-left, spring 64 impels locking bar outwards to eject at the normal condition lower spring between locking bar and lower-left pipe, the dead bolt 131 of locking bar stretches out outside the arcuate groove 131-1 of union joint, when compression poke rod spacing, locking bar overcomes spring pressure and inwardly shrinks, within the arcuate groove surface of the dead bolt withdrawal union joint of locking bar.Manage with the lower-left accordingly and be respectively equipped with 4 lockholes 5 that vertical direction is arranged on the right forward and backward vertical tube 102,104 that cooperates, the dead bolt of locking bar can cooperate the relative position between locking locking bar and the right forward and backward vertical tube with lockhole, and then locks the relative position of left rectangle pipe and right forward and backward vertical tube.Same right rectangle pipe is also by synchronous locking of the locking mechanism on the pipe of bottom right and the relative position between the left forward and backward vertical tube.
See Fig. 1 and Figure 10, when the wheelchair normal condition, seat width maximum, this moment left rectangle pipe the upper right pipe 21 spacing maximums of upper left pipe 11 and right rectangle pipe, the spacing of lower-left pipe 13 and bottom right pipe 23 is also maximum, and the lockhole of the extreme lower position on the locking mechanism on the pipe of lower-left and the right forward and backward vertical tube 102,104 cooperates locking, and the lockhole of the extreme lower position on the locking mechanism on the same bottom right pipe and the left forward and backward vertical tube 101,103 cooperates locking.When needs are adjusted the narrowed width of seats, push a left side at first simultaneously, bottom right pipe 13, the poke rod 62 of locking mechanism on 23, engaging between the dead bolt that discharges locking bar and the lockhole of front and back vertical tube, then simultaneously a left side, the bottom right pipe up lifts, a compression left side, spacing between the pipe of bottom right, this moment is left, upper right pipe also upwards rises, a because left side, right oriented tube 3,4 orientation, wheelchair frame overall shrinkage narrows down, when reaching the width that needs, discharge poke rod, the dead bolt of locking bar stretch out under the elastic force effect of spring with the front and back vertical tube on lockhole snap lock again, the width of wheelchair modifies tone to put in order and finishes, and can use.
