Specific embodiment

Below in conjunction with accompanying drawing, specific embodiment of the present utility model to be described.

This utility model provides a kind of telescopic folding type stepwise device, as seen in figure la and lb, showing for its collapsed state It is intended to, including main body 100, push rod 200, slip step 300 and folding stepped plate 400.

Main body 100 hollow, can be a part for the movable building such as single framework or caravan.Main body 100 has There is extending port 110, be made up of upper main body 120 and lower main body 130, be used for skidding off slip step 300.Extending port 110 has embedded Groove 111, embedded groove 111 is located at the end of lower main body 130.

Push rod 200 is fixed in main body 100, and one end is scalable.Push rod 200 can be hydraulic push rod, electric pushrod or gas Dynamic push rod.

The longitudinal section of slip step 300 is inShape, has horizontal plane 310 and vertical plane 320.One end of horizontal plane 310 Telescopic one end is fixed with push rod 200, and the other end is placed between main body 120 and lower main body 130；The vertical plane being attached thereto 320 are placed in embedded groove 111.Slip step 300 is passed through the structure such as chute and is slidably connected with main body 100 so as to more smooth, more steady Surely skid off from main body 100.

The bottom of one end and vertical plane 320 of folding stepped plate 400 rotates and is connected, and, folds this end of stepped plate 400 meanwhile The end face in portion is leant with embedded groove 111, makes folding stepped plate 400 be in the state being vertically arranged, and is stacked with vertical plane 320 Plus.Now, fold stepped plate 400 closing extending port 110, the flush with outer surface with main body 100, make this device in its collapsed state When it is ensured that main body 100 outer surface smooth, do not affect its outward appearance.Fold stepped plate 400 and pass through structure and the vertical planes such as hinge 320 rotate connection.

When needing to launch this device, push rod 200 extends, and slip step 300 moves, one end of its vertical plane 320 Stretch out extending port 110, meanwhile, fold stepped plate 400 and remove embedded groove 111 therewith, as shown in figures 2 a and 2b.

Now, fold the bottom end face removal embedded groove 111 of stepped plate 400, not limited, in action of gravity by main body 100 Lower turning unfolding.The slewing area folding stepped plate 400 with slip step 300 is 0-90 °, folds stepped plate 400 turning unfolding After be the level of state, now, slip step 300 and fold stepped plate 400 combination and form two grades of ladders, be the final of this device Deployed condition, as best shown in figures 3 a and 3b.

When needing to pack up this device, push rod 200 shortens, one end of vertical plane 320 of slip step 300 and fold ladder Plate 400 all moves therewith towards in extending port 110.When mobile 110 outside to extending port, vertical plane 320 not with lower main body 130 Outer wall 131 contact, fold stepped plate 400 end end face lean with the outer wall 131 of lower main body 130, as Fig. 4 a and 4b institute Show.

Push rod 200 continues to shorten, vertical plane 320 gradually retraction embedded groove 111 therewith, the folding being connected with vertical plane 320 Stepped plate 400 is limited by the outer wall 131 of lower main body 130, is flipped up, as shown in figure 5a and 5b.

When vertical plane 320 whole retraction embedded groove 111, fold stepped plate 400 limited by embedded groove 111, overturn to Vertical state, take in main body 100, close extending port, the flush with outer surface with main body 100, be this device final pack up shape State, as seen in figure la and lb.

It is also possible to only arranging slip step 300, being not provided with folding stepped plate 400, when slip step 300 in the present embodiment When stretching out extending port 110, slip step 300 independently forms step；Or, slip step 300 is placed in the one of extending port 110 End is set to multistage stairstepping, when it stretches out extending port 110, that is, forms multistage ladder.
