Integral structure of the present utility model and service routine are provided by following examples and accompanying drawing:

One. the wagon box structure division:

Fig. 1 is that the integral structure of this car launches scheme drawing;

Fig. 2 is the folding scheme drawing of this car;

Fig. 3 is a splint clasp axle construction scheme drawing.

It by about two semi-synthetic shuttle type side boards (10), bottoms connect (25) at the bottom of the hinge-type car, side board bottom, the left and right sides and folding stand (7), the quadrangle frame movable joint (8) that wheel (11), the parallel four limit type four-bar linkage in side board rear and front end be connected into is housed formed.

When using, wagon box needs only the outer group of pulling a cart, it is promptly deployable to press folding rack (7) simultaneously, with after when depositing if with portable folding support (7) simultaneously in go-cart group (10), quadrangle folding racks (7) drive at the bottom of the hinge car (25) with movable joint (8) and rise simultaneously and wagon box is shunk fold before and after this moment.

Two, manned seat structure part: it by be connected in side board back rest (6), be stuck in back rest depend on cloth (3) and cloth clamp (5) is formed.

When wagon box needs when manned to be stuck on the back rest (6) and to be stuck on the internal upper part frame of the side board left and right sides and can form front seats and back seats as long as pull-up back rest (6) will be depended on back of the body cloth (3) and cloth clamp (5), the time spent will not depended on cloth (3) and be pulled down, and back rest (6) be pressed to reset get final product.

Three. carry the patient couch top structure division: it is by being located at side board left and right sides internal upper part drawing type bed surface frame (4), live support (1), movable joint axle (2), depending on cloth (3), cloth clamp (5) and check screw (9) and formed.

When needing the delivery patient with bed surface frame (4) as required length pull out (annotate: the support alive (1) of bedstead has drawn back when launching with wagon box) fixedly wing screw (9) tighten, the time spent does not pull down and depends on cloth (3), unclamp wing screw (9), tighten wing screw (9) again after bed surface frame (4) is pushed and get final product.

Four. the handle bar structure part: it by about two semi-synthetic U type handlebar (15), roots are inserted in the car nation side registration arm (13), registration arm check screw (14), left and right sides two halves handlebar connect half dollar type axis tile (22) and axis tile obvolvent check screw (20) formed.

When the needs hutching, unclamp location tube wall check screw (14), left and right sides two halves U type handlebar (15) is turned to the front portion, after half dollar type axis tile (22) obvolvent with handlebar two obvolvent check screw (20) is tightened the height and position that mixes up handlebar (15) again by the hand push position of human body height, screwed in place tube wall check screw (14) gets final product.

Five. bicycle traction splint snap ring axle construction part: it is made up of bicycle luggage carrier (17), (23), clamping plate live axle (21), clamping plate check screw (19) (24).

Tighten with clamping plate check screw (19) (24) on the appropriate location of shelf (18) after when need draw with bicycle, earlier clamping plate (17), (23) being contained in bicycle, to locate tube wall check screw (14) unclamps, the ring (22) of embracing of handlebar end is embraced plate axle (21), check screw (19), (24) are tightened, simultaneously by shelf differing heights behind 20 " 28 " bicycle, after the adjustment of trailer car, handlebar registration arm check screw (14) tightened get final product, the time spent does not pull down by the reverse sequence of above installation and resets.

The both available bicycle of this car is pulled, also available manpower hand push can deliver various goods for family, also can supply adult, child to take advantage of seat, the anxious heavy patient of the fortune of more can lying, the time spent does not can be folded into any corner in the very little volume storage chamber, and this car modern design is simple in structure, in light weight, function is many, and cost is low, is the transportation means of family's indispensability.
