Abstract
The utility model relates to a climbing tool, in particular to a vehicle-mounted hidden type climbing ladder and belongs to the technical field of automotive equipment. The vehicle-mounted hidden type climbing ladder comprises a vehicle cross beam and the climbing ladder body, wherein two parallel guide rails are arranged in the vehicle cross beam symmetrically, a sliding mechanism and a limit mechanism are arranged in each guide rail, the sliding mechanisms and the limit mechanisms are hinged through pins, and the limit mechanisms are hinged to the upper ends of supporting columns of the climbing ladder body and a stepping pin at the top step of the climbing ladder body. According to the vehicle-mounted hidden type climbing ladder, the guide rails are arranged on the longitudinal inner side of the cross beam correspondingly, so that the climbing ladder body on the back side of the carriage can be stored in a vehicle underpan, unnecessary space of the vehicle is not occupied, and the vehicle-mounted hidden type climbing ladder is small and capable of being hidden, meeting trafficability to the greatest extent and meeting requirements for loading and unloading goods.
Description
Technical field
The utility model relates to a kind of climbing tool, is in particular a kind of vehicle-mounted hidden type crawling ladder, belongs to automobile-used technique with the apparatus field.
Background technology
The lorry or the special-use vehicle that use at present, due to the needs of loading, unloading goods, add compartment higher, and the staff of loading, unloading goods need to enter compartment by cat ladder.According to the applicant understood, cat ladder common direct and the welding of compartment afterbody or installation, cannot realize cat ladder and take in completely, thereby reduced the departure angle of vehicle, causes the crossing ability of vehicle to reduce, thereby have certain potential safety hazard.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, proposes a kind of vehicle-mounted hidden type crawling ladder that personnel load and unload goods up and down of all taking in, be convenient to again simple in structure, convenient.
In order to reach above object, vehicle-mounted hidden type crawling ladder of the present utility model, comprise crossbeam, cat ladder, in crossbeam inside, be arranged with two parallel guide rails, in described two closed slides, be equipped with slide mechanism and stop gear, described each slide mechanism and each stop gear are hinged by bearing pin, and the top bearing pin of marking time of the upper end of each pillar stiffener of described each stop gear and cat ladder and cat ladder is hinged.
Further, described slide mechanism is guide wheel, and guide wheel bottom contacts with guide rail.
Further, described stop gear comprises positioning plate and limiting stopper, and described limiting stopper correspondence is welded in the arrival end position of two closed slides, and is positioned at slide mechanism line of travel.
Further, described positioning plate is the bending plate of square, and the end that do not skid off of positioning plate is square, skids off end for bending shape open end, top the marking time of cat ladder is arranged in described bending shape open end, and described positioning plate both sides are provided with the cat ladder strut bar groove that endwisely slips.
Further, described cat ladder is four strut bars, front support rod is parallel with back support rod, describedly mark time that to be positioned at both sides back and front supporting bars inner, the guide wheel on two side rails is hinged by bearing pin and positioning plate both sides, and it is hinged with four support bar top and the top bearing pin of marking time of cat ladder respectively that positioning plate skids off the both sides of end, positioning plate and guide wheel are hinged by bearing pin, the bottom of guide wheel and guide rail slide and touch, off working state, and cat ladder is positioned at crossbeam guide rail.
The beneficial effects of the utility model: this vehicle-mounted hidden type crawling ladder utilizes the corresponding mounting guide rail of crossbeam longitudinal medial, cat ladder after compartment can be accommodated in chassis, do not take the redundant space of car body, small and hidden, meet to greatest extent trafficability, finally can meet the needs of handling goods again simultaneously; Therefore, the utility model is simple in structure, it is ingenious, easy to install to design, be not only applicable to the various vehicles that cat ladder need to be set, being also applicable to not only needs to arrange the occasion that cat ladder needs again to consider space Occupation coefficient, as loft, office space, dining room, dormitory etc.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the deployed condition structural representation of embodiment of the present utility model.
Fig. 2 is the collapsed state structural representation of embodiment of the present utility model.
Fig. 3 is the front schematic view of Fig. 1.
The specific embodiment
embodiment 1
The vehicle-mounted hidden type crawling ladder basic structure of the present embodiment is as shown in Fig. 1-Fig. 3, comprise crossbeam, cat ladder, in crossbeam inside, be arranged with two parallel guide rails, in two closed slides, be equipped with slide mechanism and stop gear, each slide mechanism and each stop gear are hinged by bearing pin, and the top bearing pin of marking time of the upper end of each pillar stiffener of each stop gear and cat ladder and cat ladder is hinged.In the present embodiment, slide mechanism is guide wheel 3, and guide wheel 3 bottoms contact with guide rail 1; Stop gear comprises positioning plate 2 and limiting stopper 5, and limiting stopper 5 correspondences are welded in the arrival end position of two closed slides, and is positioned at slide mechanism line of travel; The bending plate that positioning plate 2 is square, positioning plate 2 do not skid off end for square, skid off end for bending shape open end, top the marking time of cat ladder is arranged in bending shape open end, positioning plate 2 both sides are provided with cat ladder strut bar 4 groove that endwisely slips.In concrete making, when cat ladder is made as four strut bars, front support rod is parallel with back support rod, marking time, it is inner to be positioned at both sides back and front supporting bar, guide wheel on two side rails is hinged by bearing pin and positioning plate 2 both sides, it is hinged with four support bar top and the top bearing pin of marking time of cat ladder respectively that positioning plate 2 skids off the both sides of end, top the marking time of now installing additional effectively guarantees in the personnel's that get on or off the bus light, safe discrepancy compartment, positioning plate 2 is hinged by bearing pin with guide wheel 3, the bottom of guide wheel 3 and guide rail 1 slide and touch, off working state, cat ladder is positioned at crossbeam guide rail 1.
In the time of need to opening and using cat ladder, open door with climbing ladder or carriage back door, entrance at two side rails 1 pulls out cat ladder, at this moment guide wheel 3 drives positioning plate 2 to slide toward entrance, until limited 5 of positioning plate 2 blocks, positioning plate 2 parts are exposed outside guide rail, back and front supporting bar falls immediately, at this moment cat ladder is put down, and pedal in hinged way also launches immediately, and then cat ladder can be used.
In the time of need to packing up cat ladder, strut bar is along the axial sliding tray upward movement of pin and drive strut bar to guide rail 1 same level face, then promotes cat ladder to two side rails, and at this moment cat ladder is included in two side rails under the drive of guide wheel 3, has completed packing up of cat ladder.Finally also cat ladder is accommodated in to crossbeam inside completely, assurance door with climbing ladder or carriage back door can be closed safely.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
