Background technology
Along with the generally use of automobile, full size vehicle is on the increase, often needing to set up ladder because car door is higher facilitates personnel to step on to interior, common special vehicle is generally use the rear protecting of vehicle or side protective device as common fixing one-step foot-stool, personnel are got on or off the bus inconvenience and there is potential safety hazard, and therefore a kind of automobile-used pull ladder becomes study hotspot.
Current pull ladder is made up of platform and boarding ladder substantially, extracts platform out and launch ladder to be formed and step on car device for what step on car in compartment, as CN201218051 discloses a kind of multilevel sliding track elastic drawing ladder, and the terraced complex structure of this pull and pull is dumb; CN201110119Y discloses a safety pulling ladder, and this pull ladder realizes draw process by chute, because ladder is longer, so often there is catching phenomenon in draw process, once ladder part is got rusty, pull ladder just extremely difficulty pack up; CN203902405U discloses a kind of Foldable vehicular pull ladder, utilizes folding mode to pack up boarding ladder, and this foldable structure causes pull ladder to take up room comparatively large and structure unsightly.
Pull ladder of the prior art does not all establish handrail, and personnel are stepping in car process, and particularly for full size vehicle, car door is higher, and narrow and small steps on car space, do not establish guardrail to there is certain potential safety hazard.
Utility model content
The purpose of this utility model is for drawback of the prior art, a kind of platform-type pull ladder is provided, innovatively set up handrail, and utilize many places embedding structures to reduce pull ladder to take up room, structure is simple, pull flexibly, greatly improve the safety of stepping on car process.
The utility model is achieved by the following technical solutions:
A kind of platform-type pull ladder, comprise and step on car platform, platform handrail, ascension handle and boarding ladder, described car platform interior of stepping on has cavity structure, described cavity surface is provided with chute, described cavity inside is provided with slide block, described slide block one end is provided with roller, described roller is placed in the chute of cavity, described boarding ladder is rotatably connected to the slide block other end, described car platform two ends of stepping on are provided with bayonet lock, described platform handrail comprises two montants, two cross bars and some rack stakes, described two montants are rotatably arranged at respectively steps on car platform two ends, described two cross bars and montant are vertically installed between two montants, described two cross bars are hollow structure, two cross bars are equipped with negative thread with one end, described rack stake is arranged between two cross bars, described car platform surface of stepping on is provided with some anti-skidding flat boards, described anti-skidding dull and stereotyped interval arranges formation groove, the shape branch of described groove is consistent with platform handrail, described ascension handle is made up of stock and quarter butt, described quarter butt one end is provided with outside thread, the other end is provided with clip, the outside thread of described quarter butt and the screw-internal thread fit of cross bar use, described stock comprises one-level bar and secondary bar, described secondary bar is rotatably connected on one-level bar, described secondary bar realizes being connected by clip and quarter butt, described stock one end is provided with outside thread, the other end is provided with limit coil, the outside thread of described stock and the screw-internal thread fit of cross bar use.
The platform-type pull ladder of above-mentioned one, the internal diameter of wherein said quarter butt is less than cross bar.
The platform-type pull ladder of above-mentioned one, the internal diameter of described stock is less than cross bar.
The beneficial effects of the utility model are:
What the utility model was innovated sets up handrail, solves traditional boarding ladder and only steps on car platform and boarding ladder structure, cause and step on the problem that car process exists potential safety hazard.
First will step on car platform from level pull-out in vehicle body, again boarding ladder is pulled out from stepping on level in car platform, put to ground, chute plays position-limiting action, is turned over and turn 90 degrees to vertical state and fix with bayonet lock by platform handrail afterwards from stepping on car platform surface, the stock of ascension handle and quarter butt are extracted out from platform handrail, after fixing by internal and external threads cooperation, secondary bar be rotated down by swivel joint, use clip to fix with quarter butt, form ascension handle, complete the expansion of platform-type pull ladder.
Internal diameter due to ascension handle is less than platform handrail, and after unscrewing screw thread, ascension handle can be built in platform handrail inside completely, and limit coil and clip play position-limiting action respectively, are convenient to pull; Platform handrail by swivel joint, can making platform handrail vertical with stepping on car platform, shielding during pull-up, when putting down platform handrail can be built in completely step on car platform groove in; Boarding ladder pushes along slide block and steps on car platform, boarding ladder can be made to be built in completely and step in car landing cavity; Stepping on car platform adopts pull-out mechanism can put to interior; The built-in structure in this many places greatly reduces taking up room of pull ladder, almost only has a volume size of stepping on car platform, not only conserve space when whole pull ladder is packed up, and without the need to carrying, easy to carry.
The utility model has also set up anti-skidding flat board, steps on car safer; Adopt the design that slide block is combined with roller, the pull of boarding ladder is more flexible.
Apparatus structure of the present utility model is simple, and the expansion of platform-type pull ladder all adopts manual operations, without the need to any mounting tools with packing up.
