Detailed description of the invention
A kind of adjustable-height as shown in figs. 1 to 6 with the four-wheel travelling aided bicycle of the anti-device for folding of medicated cushion, comprise four-wheel travelling aided bicycle and medicated cushion, four-wheel travelling aided bicycle has two longitudinal axis 1, the longitudinal axis 1 two ends connect handle 2 and roller shaft 3 respectively, concavoconvex segment is provided with in the middle part of described two longitudinal axis 1, and the position of two longitudinal axis concavoconvex segments parallels, concavoconvex segment is apart from identical, every root longitudinal axis 1 is provided with an elevating bracket 4, this elevating bracket 4 is stuck in the groove of the concavoconvex segment of the longitudinal axis 1 by built-in transverse axis 41, and built-in transverse axis 41 outside has movable cushion block 5 to be therewith inserted in groove with fixing elevating bracket 4 position, medicated cushion is then fixed by latch 6 and elevating bracket 4.
Elevating bracket as shown in Figure 4,5, elevating bracket inside 4 is provided with built-in transverse axis 41, clamps built-in transverse axis 41, the adjacent movable cushion block 5 of built-in transverse axis 41 by nut 42 and the fixed block 43 being welded on elevating bracket 4 inside, elevating bracket 4 outside is provided with the one group of through hole 44 paralleled, and interts in order to latch 6.
Medicated cushion as shown in Figure 6, be made up of two pieces of seat boards 71 and folder one piece of No. two seat board 72 therebetween, a seat board 71 and No. two seat board 72 active links, described two pieces of seat boards 71 and No. two seat board 72 surfaces are fixed by one group of seat belt 76, No. two seat boards 72 offer one group of through hole 721, insert in through hole 721 by the anti-down handle 74 with pivot pin 73, the outside being positioned at anti-down handle 74 at pivot pin 73 is provided with return spring 75, the outside that described anti-down handle 74 is positioned at pivot pin 73 is respectively provided with a projection 741, the position of two pieces of corresponding anti-down handle 74 projections 741 of a seat board 71 is respectively provided with a counterbore 711, counterbore 711 is fitted mutually with protruding 741 sizes, protruding 741 can snap in counterbore 711, described two pieces of seat boards 71 all have a through hole 712, intert in order to latch 6, concrete, the length of described anti-down handle 74 is greater than No. two seat board 72 side width, and the projection 741 on anti-down handle 74 is beyond No. two seat board 72 sidepieces, when anti-down handle 74 inserts No. two seat boards 72, two projections 741 and the counterbore 711 snapped in respectively on a seat board 71.
This utility model specifically works like this: first snap in the concavoconvex segment of the longitudinal axis by built-in for elevating bracket transverse axis, then movable cushion block is inserted, now fix the position of elevating bracket and whole carriage, then medicated cushion is corresponding with elevating bracket through hole separately, latch is inserted, the position of fixing medicated cushion.When carriage does not use, folding medicated cushion, folds by a seat board and No. two seat boards, and the width that now width of whole travelling aided bicycle is about No. two seat boards extremely saves floor space, when carriage will be used, open medicated cushion, make a seat board and No. two seat boards in same level, and insert anti-down handle, now, projection due to anti-down handle snaps in the counterbore of a seat board, whole medicated cushion i.e. two pieces of seat boards, No. two seat boards and anti-down handle are positioned at a plane simultaneously, because anti-down handle and a seat board, No. two seat boards are not point-blank, the horizontal plane of these 3 part compositions has and only has one, therefore medicated cushion will become unique plane, no longer collapsible, greatly reduce user because the sticky feeling brought amounted to voluntarily by medicated cushion.When no longer needing to use, only needing return spring to be pressed the anti-down handle of pull-out, between a seat board and No. two seat boards, becoming again collapsible pattern.
