The utility model can be regarded as on the back leg of former two sides turnover folding chair and set up a reserve seat again, when making folded seat be deployed into balance position, has possessed dull and stereotyped shape, at the back side of two seat supports caster wheel is installed, and makes it really to have become activity flatcar easily.Adorn four castors on original seat support, these four castors have been fixed a plane with after ground contacts, and adorn two castors on the reserve seat, and are hinged by back leg and preceding seat support because of reserve seat, also are fixed up in the plane of reserve seat.These two seat supports both can be in same plane, also can be not in same planes, and flatcar can adapt to irregular ground by the adjusting of two interplanar angle itself, has reduced the flatcar internal stress simultaneously, has increased durability.All castors all are directly installed on the two seat support back sides, make that suffered gravity directly reaches ground by castor on two seat supports, and power suffered on the chair leg steel pipe can be reduced to bottom line.Plank upside and every castor corresponding position are provided with a steel plate washer in the seat support, every pad and castor are fixing opens square opening with the hole correspondence position, the square nut of spoke cap shape is placed in the square hole, pass plank, screw with castor one side is fixed on castor on the seat support, such structure both can be gained in strength, and can change castor under the condition of not pulling down seat support again.Adopt between tool shelf and chair leg steel pipe to articulate, load onto tool shelf when repairing, at ordinary times with tool shelf and chair decomposition storage.

During automobile bottom et out of order, most applications is that the driver directly climbs to below the car at the bottom of the tool car, because of the car base space very little, climb into and climb out of all inconveniences, repair at the bottom of the train, the driver will roll all over the body dirt at least, to winter and this work in rainy season just more arduous, at the convenient time, they may transfer mat, plank or a plastic cloth etc. at car.This shows, at home the technology of this respect person blank almost.Be bound to improve automobilist's service conditions in this respect after using the utility model, and can increase work efficiency.Although have melt pit or repairing table in some garage, that is finished is a bigger fixed buildings, and the utility model is compared with it has light characteristics, is not subjected to the restriction of conditions such as time place in the use.

Figure (1) is the lateral plan that the utility model is the chair state, the local figure of figure (1) upside be among the figure (2) relevant tool shelf (14) partly the B-B section-drawing and C to birds-eye view, dashed line view representational tool dish (14) can decompose with preceding chair leg (2).Figure below of figure (2) is the lateral plan that is the flatcar state, and the last figure of figure (2) is the ground plan of flatcar state.Preceding chair leg (2) and back leg (1) all are the U-shaped tubular constructions, and the two is fixing by chair transverse axis (4), and can swing around chair transverse axis (4).After the reserve seat (3) set up be fixed on the back leg (1), seat support (6) is fixed on the fillet U-shaped steel pipe seat support (7), castor (9) has four back sides that are installed in seat support (6), two back sides that are fixed on reserve seat (3) are arranged, and the two ends of backrest (11) are plugged in the two inboard holes of preceding chair leg (2) upper end with pin.Slide bar (13) passes seat support (6) and seat support frame (7), and in the guide groove (16) before two ends are stretched on the chair leg (2), during mapping function, slide bar (13) slides along guide groove (16).All castors and reserve seat (3) are all inoperative when being the chair state, and tool shelf (14) does not articulate, and all the other each component functions and former folded seat are identical.Is the flatcar state along direction shown in the arrow among the figure (1) by the chair state exchange.At this moment reserve seat (3), seat support (6) and backrest (11) are in same plane, and when the driver physical first half was lain on the back on flatcar, reserve seat (3) supported buttocks, and seat support (6) supports the back, and backrest (11) holds up head.Four castors (9) are fixed seat support (6) plane unlikelyly to topple over, and two castors (9) support reserve seat (3) in addition, and are hinged by two rivets (5) because of the two ends and the seat support frame (7) of back leg (1), and the plane of reserve seat (3) also is fixed.Under the supporting role of chair transverse axis (4) and slide bar (13), chair leg (2) is fixing before making, thereby the backrest (11) on the chair leg (2) also is in the plane of two seat supports before making.Gravity major part on the reserve seat (3) directly reaches ground after passing to two castors (9) at its back side, small part gravity is by back leg (1), hinged rivet (5) and seat support frame (7) are passed to seat support (6), and the last suffered gravity of seat support (6) and this part power reach ground by four castors (9) at its back side.Backrest (11) is gone up suffered gravity and is passed to capable again distribution behind seat support (6) and the back leg (1) by preceding chair leg (2), slide bar (13) and chair transverse axis (4).Back leg (1) can be swung around rivet (5), preceding chair leg (2) and back leg (1) can be swung around chair transverse axis (4) again, slide bar (13) also is movable, thereby seat support (6) and reserve seat (3) can be or not same planes, and the plane of backrest (11) is determined by above two planes, therefore can adapt to irregular ground by the adjustment of self.During the flatcar state tool shelf (14) is articulated on the mount hole of preceding chair leg (2) with hook (15), uses instrument but band portion repairs.Fix screw (12) is fastening as a whole respectively with each layer of reserve seat (3), seat support (6), and reserve seat (3) is fixed on the back leg (1), seat support (6) is fixed on the seat support frame (7), castor (9) also makes the resistance of motion of flatcar reduce, turns to flexibly except that supporting role.

Realize that the utility model should select to have the folded seat pattern that structure is turned on the two sides, this folded seat when dull and stereotyped state, its thickness minimum length maximum, the front of original seat support (6), newly-increased reserve seat (3) and backrest (11) all is in same direction.Two seat supports (3), (6) can be made by hard rubber flaggy, plank layer, sponge layer and leather surface from bottom to top, and seat support frame (7) is used steel tube bending, joint to connect the inboard solid welding of seat support frame (7) and used steel disc surely, perforate on the steel disc.Plank layer, sponge layer and leather surface be at the steel disc upside, and hard plastic sheet is at the fixing steel disc downside of using, and passes perforate and plank on hard plastic sheet, the steel disc with wood screw, and seat support (6) and seat support frame (7) are fixed together.Newly-increased reserve seat (3) and the fixing means between back leg (1) steel pipe are the same.Establish one on square bar pad with flat board (10) corresponding position in that plank layer upside and each castor are fixing, every steel plate washer and castor fixed orifice correspondence position are opened square opening, the screw (8) that spoke cap shape square nut is pierced into steel plate washer side and plank and castor one side is fastening, realizes the installation of castor.The available steel plate compacting of tool shelf (14).Hook (15) on two jiaos of the long sides of tool shelf (14) can be welded on the tool shelf (14).In preceding chair leg (2) correspondence position perforate, in order to the mounting tools dish.
