Description

Multi-purpose folding flatbed tricycle for servicing cars

The utility model relates to a kind of collapsible flat truck, particularly a kind of maintenance that is used for the automobile bottom, the universal folding vehicle maintenance and repair flat truck that small lot portage and personnel have a rest.

When needing repairing the automobile bottom, there be not ground to repair under the situation of ditch, the repairman often adopts seat cushions or other pad body thing, directly lies in sometimes and carries out maintenance operation on the ground.Not only labor condition is poor for this, and moves difficulty.The maintenance wheel pad that the repairman who has at present adopts or the pad that crouches, what have can fold, and what have can not fold.Although provide more convenient car bottom recovery equipment to the repairman,, made its whole height excessive (greater than 10 centimetres), so result of use is very undesirable because of its roller is to be fixed on the poppet.Particularly narrow space at the bottom of car is difficult to its effect of performance.

The purpose of this utility model provides a kind of universal folding vehicle maintenance and repair flat truck, and it is not only simple in structure, has reduced the overall height of car effectively, and easy disassembling, uses flexibly, and is easy to operate, puts neat appearance.

The purpose of this utility model is achieved in that vehicle body adopts case structure, forms by hinges is hinged.Deposit the not time spent, vehicle body is amounted to into box or back cushion type, can placement activity bolster, pushing hands in the vehicle body concave surface cavity and the car repair tool case of wheel carrier, cardan wheel is housed.When keeping in repair, open vehicle body, plug the universal wheel of movable bolster, circumscribed that has illuminating lamp, hang up the car repair tool case lid, can carry out work easily.As after work, also can lie on the vehicle body and have a rest, as snug as a bug in a rug.When carrying small lot goods, take off movable bolster, plug pushing hands, with vehicle body cargo transport, light laborsaving.

The utility model has reduced the overall height of car, so to space narrow at the bottom of the car, personnel pass in and out also very freely owing to adopt the circumscribed cardan wheel.Instrument is whipped desirable very convenient.Have illuminating lamp on the movable bolster, help night time operation.The universal wheel of circumscribed is fixed on the vehicle body in the mode of pegging graft in addition, when amounting to vehicle body, puts into the tool box under desirable.Than the existing vehicle body that has the formula roller that is fixedly connected, amount to and put neat appearance.

Describe concrete structure of the present utility model in detail according to Fig. 1～13.The vehicle body 1 of this car adopts case structure, and is hinged by hinge 3.The flat end utilization of vehicle body 1 is lined with the fabricate-leather parcel of foamed gaskets, is shaped on reinforced rib 9 in the concave ends cavity.The frame 7 of vehicle body 1 is shaped on

socket

2,8 and 11, can insert the wheel carrier 12 of car repair tool case lid, movable bolster 5 and the universal wheel of circumscribed respectively.In the movable bolster 5 illuminating lamp 6 and battery case are housed.Inserted link on the utilization activity bolster 5 can be plugged in the socket 8 of vehicle body 1 frame 7 easily, and movable bolster 5 is assembled on the vehicle body 1 securely.Have spring clip on the wheel carrier 12 of the universal wheel of circumscribed, wheel carrier 12 is inserted firmly in socket 11, the overall height of assembling back car is 4～10cm.Cardan wheel 13 fuses by screw thread with the sliding sleeve that has spring clip, is plugged on the wheel carrier 12.In socket 8, also can insert pushing hands 14, so that carrying small lot goods.Pushing hands 14 can be made sleeve type structure or spring rack and panel construction.The wherein pushing hands 14 of sleeve type structure, fix a pole in slide bar 16 ends that have handle 15, slide into the end of slide bar 16 for 17 times when the sliding sleeve that is hinged with travel(l)ing rest 18, pole on jack on the travel(l)ing rest 18 and the slide bar 16 is joined, and the inserted link of pushing hands 14 by travel(l)ing rest 18 ends is inserted in the socket 8 on the vehicle body 1 again.On the slide bar 16 of spring carriage formula structure jump ring 19 is arranged, the travel(l)ing rest 18 that is hinged on the sliding sleeve 17 can be reinforced in the lower end of slide bar 16, again pushing hands 14 is inserted in the socket 8 on the vehicle body 1.

When the utility model does not use, the sliding sleeve 17 of pushing hands 14 can be received the end of slide bar 16, put into the cavity of vehicle body 1, and then put into movable bolster 5 near handle 15.Take off the wheel carrier 12 and the cardan wheel 13 of the universal wheel of circumscribed, put into the car repair tool case, again the car repair tool case is also put into the cavity of vehicle body 1.Utilize handle 10 that vehicle body 1 is amounted to into box, put housing-case 20 and preserve.Also vehicle body 1 can be amounted to into automobile-used back cushion type (as Figure 12), promptly not take off movable bolster 5, be directly installed on the seat in the operator's compartment, make back cushion and use.

When carrying out maintenance work, remove the housing-case 20 that the utility model is amounted to into box, launch vehicle body 1, take out in the chamber and deposit article.At first open the car repair tool case, cardan wheel 13 is inserted wheel carrier 12 form the universal wheel of circumscribed, be assembled in again on the vehicle body 1.Climb over vehicle body 1 then, insert firmly movable bolster 5, again the instrument case lid is inserted on the socket 2 of vehicle body 1 one sides, the repairman lies on the back on vehicle body 1, the movable bolster 5 of headrest is stepped on ground or with corresponding site at the bottom of the hand barrow with pin, can pass in and out car easily at the bottom of any position keep in repair.As insufficient light, start switch, utilize illuminating lamp 6 to increase brightness.Recovery equipment is placed in the tool box and covers, and is desirable conveniently, sends without other people, very convenient.The driver and conductor also can utilize vehicle body 1 to have a rest, and it is also very comfortable thereon to lie.When needs carrying small lot goods, because of not needing to limit bodywork height, can directly cardan wheel 13 be inserted on the vehicle body 1, as long as take off movable bolster 5 and instrument case lid, plug pushing hands 14, can transport goods.When particularly vehicle body 1 folding back being become back cushion type (as Figure 12), also can utilize the back cushion on the existing indoor seat of vehicle drive of the utility model replacement.Like this, both can make full use of the finite space of operator's compartment, the utility model is put suitably, minimizing takes up room, and back cushion can become the flat truck of maintenance usefulness and the pad for sleeping in of rest usefulness again after taking off assembling, realizes one-object-many-purposes.
