Summary of the invention
It is an object of the invention to provide a kind of simple in construction, convenient maintenance, low cost, the folded turnover formula access step taking up room less.
The present invention is achieved by the following technical programs:
A kind of folded turnover formula access step, including collapsible ladder, ladder storage stopping means and ladder locking device, both sides, described collapsible ladder upper end respectively be positioned at shelter or van to step on car platform rear end hinged, described ladder storage support means is arranged on steps on car platform both sides, including being fixed on the positive stop strip stepped on inside the bulkhead of top, car platform one end and to be fixed on the limit base stepped on the car platform other end, described positive stop strip and limit base corresponding with position, collapsible ladder both sides respectively;Described ladder locking device includes 2 resilient pins and 2 pieces of lockplates, and 2 resilient pins are separately fixed on the upside of ladder side and limit base, 2 pieces of lockplates and 2 resilient pin position one_to_one corresponding, is separately fixed at and is arranged on ladder side.
Aforesaid folded turnover formula access step, wherein said collapsible ladder includes that ladder and lower ladder, upper ladder lower end and lower ladder upper end are by a pair hinge.
Aforesaid folded turnover formula access step, wherein said limit base is flute profile, the bottom surface of described flute profile is fixed on to be stepped on the car platform other end, one resilient pin is fixed on flute profile end face, another resilient pin is fixed on ladder side, and 2 pieces of lockplate one end are separately fixed on lower ladder side one on the other;After upper ladder and lower ladder fold, the resilient pin of upper ladder side is locked on one piece of lockplate of lower ladder side;After the upper ladder folded and lower ladder are flipped up, the resilient pin on the upside of limit base is locked on another block lockplate of lower ladder side.The flute profile vertical of limit base is provided with rib, and described rib is corresponding with positive stop strip lateral location;After upper ladder and lower ladder folded turnover, lower ladder side is resisted against on rib, and lower ladder opposite side is resisted against on positive stop strip side.
Aforesaid folded turnover formula access step, is provided with flute profile decorative panel on rear side of wherein said upper ladder, after the storage of folded turnover formula access step, the bottom surface of flute profile decorative panel is outwardly.
Aforesaid folded turnover formula access step, wherein steps on front side of car platform the corresponding position with upper ladder upper end and is provided with the positioning seat being inverted V-arrangement, when folding ladder launches to use, tilts to be resisted against on the inclined-plane of positioning seat on rear side of upper ladder upper end.
Present configuration is simple, easy to maintenance, low cost of manufacture, take vehicle mounted square cabin or van space little, safe and reliable, pull out resilient pin, the present invention just can be launched use;During the storage present invention, upper ladder and lower ladder are turned into vertical state and are accommodated into and step on car platform after folding, folded state just can be locked by upper ladder and lower ladder by a resilient pin, just the upper ladder of folded state and lower ladder can be locked on limit base by another resilient pin, locking is reliable, very easy to use, receives and launches simple and quick, and take vehicular platform space not too much, moreover it is possible to ensure aesthetic property.
Advantages of the present invention and feature, by for illustration and explanation by the non-limitative illustration of preferred embodiment below, these embodiments, it is only used as example referring to the drawings and is given.
Accompanying drawing explanation
Fig. 1 is the structural representation of receiving state of the present invention;
Fig. 2 is the structural representation of deployed condition of the present invention;
Fig. 3 is the right view of Fig. 2.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, the present invention includes collapsible ladder 1, ladder storage stopping means 2 and ladder locking device 3, collapsible ladder 1 includes ladder 11 and lower ladder 12, upper ladder 11 lower end and lower ladder 12 upper end are hinged by a pair hinge 13, both sides, collapsible ladder 1 upper end respectively by a pair ladder hinge 14 be positioned at shelter or van to step on car platform 4 rear end hinged.
Ladder storage support means 2 is arranged on steps on car platform 4 both sides, including being fixed on the positive stop strip 21 stepped on inside car platform 4 right-hand member top bulkhead 5 and to be fixed on the limit base 22 stepped on car platform 4 left end, positive stop strip 21 and limit base corresponding with 1 liang of side position of collapsible ladder respectively.Positive stop strip 21 available angle steel is made, and is fixed on 2 trip bolts 221 and steps on car platform 4 right-hand member top bulkhead 5;Limit base 22 is the bending sheet metal component in flute profile, and 4 trip bolts 221 of the underrun of flute profile are fixed on to be stepped on car platform 4 left end.
