The purpose of this utility model is to finish by following technical scheme.

The utility model is a kind of collapsible ladder, comprises two side bars, is fixed with the plurality of fixed pedal between two side bars, it is characterized in that:

Also comprise handrail, expansion link, Foldable pedal, supporting leg, connecting rod, cross bar, securing rod, locking spring, an end of two described supporting legs each with the top of two described side bars with spool being hinged and connected; Each is connected two ends of described cross bar mutually with described two supporting legs;

One end of described Foldable pedal is with the hinged end that is connected in the fixed pedestal that is positioned at the top of jointed shaft, and the other end of Foldable pedal is bearing on the described cross bar;

Described expansion link is arranged in described side bar longitudinally-slidablely, has the place, location on described expansion link, and the top of described expansion link links to each other with the described handrail of going up;

One end of described connecting rod is hinged on the described expansion link, and the other end is hinged on the described supporting leg.

In a fixed pedestal, two securing rods are housed, the locking spring is housed between the adjacent end portion of described two securing rods, under the locking spring action, the other end of two securing rods is pressed to the place, location of expansion link.

The utility model adopts the ladder of band platform and last handrail, adds Foldable pedal on the fixed pedestal at top, makes at the top of ladder and forms platform jointly by fixed pedestal and Foldable pedal.Expansion link is housed on side bar, side bar is locked, form handrail, be convenient to stand in when working above the platform stable, convenient, safety with securing rod and locking spring.When folding, pinch lock hook, make the other end of securing rod break away from expansion link, then can be with expansion link along the downward landing of side bar; And drive the downward landing of connecting rod one end, and supporting leg and side bar are drawn close, this moment, Foldable pedal fell around jointed shaft, and drew close with side bar, finished folding.

In sum, the utility model has solved in the use of existing ladder, less stable, and work is inconvenient, also safe inadequately shortcoming.The utility model can lean on the wall and use, and stand in when working on the platform, and is stable, convenient, safety; And it is simple in structure, and is collapsible, and accumulating is convenient.

Code name explanation among the figure

3 side bars are located in handrail 2 expansion link 2A, 2B location on 1

Groove 4 Foldable pedals 5 supporting legs 6 connecting rods of 3A opening

7 fixed pedestals, 8 cross bars, 9 securing rods, 10 locking pike poles

11 locking springs, 12,13 jointed shafts, 14 connecting plates

The specific embodiment

Be example with the telescopic miniature ladder of the utility model product below, the utility model is illustrated.

As Fig. 1,2 is structural representation of the present utility model, comprise two side bars 3, between two side bars 3, be fixed with plurality of fixed pedal 7,

Also comprise handrail 1, expansion link 2, Foldable pedal 4, supporting leg 5, connecting rod 6, cross bar 8, securing rod 9, locking spring 11,

Each is hinged and connected one end of two described supporting legs 5 with spools 12 with the top of two described side bars 3; With reference to Fig. 3, each is connected two ends of described cross bar 8 mutually with described two supporting legs 5;

With reference to Fig. 1,4, an end of described Foldable pedal 4 (two sides) is with jointed shaft 13 hinged ends that are connected in the fixed pedestal 7 that is positioned at the top, and the below of the other end of Foldable pedal 4 has recess 4A and is bearing on the cross bar 8;

With reference to Fig. 3, an end of described expansion link 2 is slidably located among the groove 3A of opening of described side bar 3, and with connecting plate with groove 3A in the upper, middle and lower three places sealing of 14 (Fig. 1) with opening; On described expansion link 2, has the 2A (Fig. 5) of location place, the top of expansion link 2 and the described handrail 1 link to each other (Fig. 2) of going up;

Two ends of connecting rod 6 all have the curved termination that turn 90 degrees, and an end and expansion link 2 lower ends hinged (Fig. 1,3), the other end and supporting leg 5 are hinged,

Two securing rods 9 laterally are housed in the fixed pedestal 7 on top, with reference to Fig. 5,6, locking spring 11 are housed between the adjacent end portion of described two securing rods 9, under 11 effects of locking spring, the other end of two securing rods 9 is pressed to the 2A of place, location of expansion link 2.In the present embodiment, the 2A of place, location on the expansion link 2 is hole (also can adopt other forms such as latch), and the termination of securing rod 9 is inserted in this hole.

When folding, pinch locking pike pole 10, make the other end of securing rod 9 break away from expansion link 2, then can be with expansion link 2 along side bar 3 downward landings; The left end that drives connecting rod 6 falls, and supporting leg 5 and side bar 3 are drawn close, and this moment, Foldable pedal 4 fell around jointed shaft 13, and drew close with side bar 3, finished folding; At this moment, the other end of securing rod 9 is inserted the 2B (Fig. 1) of another place, location of expansion link 2 upper ends, to lock this folded state, shown in Fig. 7,8.

When opening this ladder, at first pinch locking pike pole 10 and make securing rod 9 withdrawal and throw off with expansion link 2; Loosen then the locking pike pole 10, on carry this handrail 1, mention desired location together with expansion link 2, connecting rod 6; Under the effect of locking spring 11, make the end of securing rod 9 be inserted into the 2A of place, location of expansion link 2, lock this handrail 1, form duty.
