Detailed description of the invention
Fig. 1 be the utility model proposes a kind of portable folding ladder structural schematic diagram；
Fig. 2 be the utility model proposes a kind of portable folding ladder overlooking structure diagram.
In figure: 1 bottom plate, 2 support rods, 3 casings, 4 handles, 5 first connecting rods, 6 guide rods, 7 bar shaped gears, 8 support frames, 9
Limit plate, 10 sliding shoes, 11 rotor plates, 12 fixed blocks, 13 springs, 14 gears, 15 sliding panels, 16 second connecting rods, 17 cabinets,
18 idler wheels.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of portable folding ladder, including bottom plate 1 are welded with support rod 2 at the top of the bottom plate 1, support
Cabinet 17 is welded at the top of bar 2,17 inner wall of cabinet is welded with guide rod 6, and 6 internal activity of guide rod is socketed with sliding shoe 10, described to lead
6 bottom of bar offers notch, and 10 bottom of sliding shoe is welded with fixed link, and fixed link passes through 6 bottom plate rabbet of guide rod, and fixed link is another
One end is welded with bar shaped gear 7, and 17 inner wall of cabinet is welded with bar, and the outside activity of bar is connected with support frame 8, the weldering of 17 bottom of cabinet
It is connected to casing 3, spring 13 is welded at the top of 3 inner wall of casing, 13 other end of spring is welded with sliding panel 15, the weldering of 15 bottom of sliding panel
It is connected to the second connecting rod 16, the second connecting rod 16 passes through casing 3, and 16 one end of the second connecting rod is movably installed with idler wheel 18.
In the present embodiment, swing handle 4, handle 4 drives first connecting rod 5 to rotate, and first connecting rod 5 is with 14 turns of moving gear
It is dynamic, because gear 14 and bar shaped gear 7 are intermeshed, so the rotation of gear 14 drives bar shaped gear 7 to move along 6 direction of guide rod,
Bar shaped gear 7 drives sliding shoe 10 to move, and 17 side of cabinet offers through-hole, and bar shaped gear 7 may pass through 17 through-hole of cabinet, sliding
The movement of block 10 drives support frame 8 to rotate, and rotates rotor plate 11, the bar on 11 side wall of rotor plate is made to fairly fall in 8 top of support frame
In groove, at this moment operator climbs up rotor plate 11 by fixed block 12, realizes the function of ladder, when operator does not climb up admittedly
When determining block 12, due to 13 elastic force of spring act on, wheel 18 and ground face contact, bottom plate 1 not with ground face contact, when operator climbs up
When fixed block 12, spring 13 is made to be in compressive state, at this moment bottom plate 1 touches ground, ensure that wheel 18 will not roll, also protects
The position for having demonstrate,proved folding ladder will not change.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
