Abstract
The utility model discloses a folding handrail of a boarding ladder. The folding handrail comprises a handrail body, a corner piece, a first movable rod, a second movable rod and threaded sleeves, wherein one end of the first movable rod and one end of the second movable rod are movably connected with the corner piece respectively, and the other end of the first movable rod and the other end of the second movable rod are movably connected with the handrail body respectively; the threaded sleeves are respectively arranged at the joint of the first movable rod and the corner piece and the joint of the first movable rod and the handrail body; the corner piece is connected with the boarding ladder; when the handrail body is folded up, the threaded sleeves are screwed off; and after the threaded sleeves extend out of the connection pieces, the movable rods are folded up towards the same direction at the same time. The folding handrail of the boarding ladder is arranged on the side face of the boarding ladder, so that people can conveniently board on a train by holding the handrail, and the safety of people can be guaranteed; after the sleeves are screwed off, the handrail can be folded up and occupies a very small height space; the handrail and the boarding ladder are together collected; and the operation is convenient and labor-saving.
Description
Technical field
The utility model relates to steps on the companion-way stow-away arm rest, particularly relates to a kind of pull and steps on the companion-way safety rail, specifically is that a kind of pull that can be installed in is stepped on companion-way and can be stepped on the handrail that companion-way is collected and used with pull.
Background technology
In recent years, the application of shelter more and more widely, type and the form of shelter annex are also enriched constantly thereupon, wherein step on companion-way as the requisite annex of shelter, play the effect that makes things convenient for personnel to pass in and out shelter or shelter is operated when shelter does not land on year car.Step on companion-way at present and be divided into mainly that packaged type is stepped on companion-way and drawing and pulling type is stepped on companion-way, packaged type step on companion-way not the time spent be stored in the terraced box or hang on the bulkhead, will step on companion-way in the time of need stepping on the cabin and take out on the hook that hangs over shelter or carrier loader platform.It then is to link into an integrated entity with terraced box that drawing and pulling type is stepped on companion-way, steps on directly to pull out when use in the cabin to land to use to get final product.Present two kinds step on companion-way all not the consideration personnel step on unstability in the process of cabin do not step on cabin handrail, the safety in the time of can not guaranteeing to step on the cabin because restraining factors such as space are installed.
Chinese patent literature CN99238437.0 discloses a kind of stow-away arm rest in 2000.09.06, it is made up of gripper shoe, handrail and the hinge of the tank that has individual layer and double-deck guide rail, two ends band pin, one end of two tanks connects with hinge, the pin at gripper shoe two ends is installed in respectively on the guide rail of two tanks, and handrail inserts and has on another layer guide rail of double-deck guide rail tank.
Chinese patent literature CN201110186108.0 discloses a kind of Foldable handrail in 2012.01.25, described handrail is characterised in that it comprises a deformable body, first end of body rotates with respect to the chair back according at least one lateral shaft, and its second end rotates with respect to described seat support according at least one lateral shaft.
The problem that above-mentioned two kinds of patents solve is different with the utility model, realizes the principle difference.
The utility model content
The utility model purpose: the utility model provides a kind of companion-way stow-away arm rest of stepping on, and the collapsible handrail that dwindles takes up room when stepping on the companion-way collection, improves and steps on the cabin safety.
Technical scheme:
A kind of companion-way stow-away arm rest of stepping on comprises handrail (1), bent angle (2), first motion bar (3), second motion bar (4) and screw shell (8); One end of first motion bar (3) and second motion bar (4) flexibly connects with bent angle (2) respectively, and the other end flexibly connects with handrail (1) respectively; First motion bar (3), second motion bar (4) flexibly connect with handrail (1) and bent angle (2) by connector (5) and axle (7) respectively; First motion bar (3) is respectively equipped with screw shell (8) with the junction of bent angle (2) and handrail (1); Screw shell (8) is enclosed within the end of connector (5) and first motion bar (3).Bent angle (2) with step on companion-way and be connected.First motion bar (3) and second motion bar (4) are made up of some connectors (5), adopt wedge shape to tighten structure and fix;
Collapsible when stepping on the companion-way collection, wherein a bar can be fixed handrail and bent angle by the screw shell of tightening on it (8).
Beneficial effect:
The utility model can be stepped on companion-way and collects together along with pull, takies very little space, only needs when becoming collecting state from the use state screw shell unscrewed to get final product; Handrail is consistent with the upper-deck cabin angle of stepping on companion-way under the use state, makes things convenient for personnel to hold up and holds, and guarantees the safety of upper-deck cabin.Screw shell adopts wedge structure, guarantees that screw thread can not become flexible under the handrail use state, has improved the safety of stepping on companion-way.
