Specific implementation mode

The utility model is described in further detail with reference to the accompanying drawings and examples.

As shown in Fig. 1~Fig. 6, the utility model includes ladder 1 and the armrest system 2 that is arranged outside 1 side of ladder, ladder 1 top is equipped with the hook 3 being connect with vehicle chassis, in use, hook 3 is hooked on the link of vehicle chassis end face, ladder 1 Bottom supports on the ground.Armrest system 2 includes 23,2 22 upper ends of supporting rod of 21,2 supporting rods 22 of bar and lock It is hinged with the downside of bar 21 respectively, lower end respectively with to be fixed on corresponding limit base 4 outside 1 side of ladder movably hinged, 21,2 supporting rods 22 of bar constitute the four bar linkworks that can be swung with 1 side of ladder.Lock 23 is vertical along ladder 1 To being fixed on 1 outside of ladder, 232 vertical welding of lockplate is fixed on 21 right end of bar.When bar 21 is stored, locking 231 head of resilient key of device 23 puts in locking bar 21 in lockplate 232.When bar 21 is unfolded, 231 head of resilient key is de- Bar 21 is set to unlock from lockplate 232,2 22 lower ends of supporting rod are locked in respectively in corresponding limit base 4.

As shown in Figure 3 and Figure 5, supporting rod 22 includes sequentially integrally welded upper hinged seat 221, intermediate round steel pipe 222 and lower articulated joint 223, the bar articulated joint 211 of upper hinged seat 221 and 21 downside of bar passes through upper swivel pin 213 and cuts with scissors It connects, lower articulated joint 223 is movably hinged by lower swivel pin 224 with limit base 4.

Lower articulated joint 223 is cuboid, and the longitudinal middle part of the cuboid is equipped with slotted hole 225, lower swivel pin 224 Across the slotted hole 225 of limit base 4 and lower articulated joint 223, slotted hole 225, but also can be around so that supporting rod 22 can not only move up and down Lower 224 axial line of swivel pin rotation, to make the lower articulated joint 223 of 22 lower end of supporting rod that can be locked in limit base 4, unlock It can be rotated again around 224 axial line of lower swivel pin afterwards, realize the expansion and storage of bar 21.

It is equipped with as shown in figure 5, limit base 4 includes the sleeve 41 that weldering is linked together and fixed plate 42,41 center of the sleeve Rectangular opening 411 up and down.When the expansion of supporting rod 22 is holded up, the lower articulated joint 223 of cuboid is injected and its clearance fit Rectangular opening 411 in so that 22 lower end of supporting rod is locked, and lower swivel pin 224 passes across sleeve 41 and lower articulated joint 223 Slotted hole 225 so that 22 lower end of supporting rod is hinged with limit base 4.41 side of sleeve be equipped with notch 412, the width of notch 412 with The width of lower articulated joint 223 matches, when bar 21 is stored, the lower articulated joint 223 of 22 lower end of supporting rod can rotate 90 ° against On the bottom surface of notch 412, supporting rod 22 is made to be locked in the receiving state of lodging.Two brackets 5 are fixed on outside 1 side of ladder, When bar 21 is stored, downside is resisted against on bracket 5.

When bar 21 is unfolded, then the connection of first unlock device 23 and lockplate 232 on bar 21 gets a grip on the rail Bar 21 moves up, and bar 21 and supporting rod 22 are rotated counterclockwise around lower swivel pin 224, until supporting rod 22 turns to and ladder 1 When side is vertical, bar 21 is pushed, so that the lower articulated joint 223 of 22 lower end of supporting rod is injected in the rectangular opening 411 of sleeve 41 and locks Supporting rod 22 is determined, so that bar 21 and 2 supporting rods 22 are stablely supported on 1 left side of ladder.

When bar 21 is stored, bar 11 is above carried, the lower articulated joint 223 of 22 lower end of supporting rod is made to be detached from the square of sleeve 41 Shape hole 411, supporting rod 22 unlock, and then bar 21 and supporting rod 22 are pushed to be rotated clockwise around lower swivel pin 224, directly It turns to be parallel on the downside of 1 left side of ladder and bar 21 to bar 21 and be resisted against on two brackets 5, while making lock 231 head of resilient key on 23 puts in lockplate 232, completes the storage locking of bar.

In addition to the implementation, the utility model can also have other embodiment, all to use equivalent replacement or equivalent change The technical solution to be formed is changed, is all fallen in the protection domain of the requires of the utility model.
