Detailed Description

The core of the utility model lies in providing a folding ladder of hanging, thickness under fold condition is irrelevant with the width of footboard self, thus can set up great width, does not increase the stability of the footboard on the basis of volume.

In order to make those skilled in the art better understand the technical solution of the present invention, the following will describe the folding hanging ladder in detail with reference to the accompanying drawings and the specific embodiments.

The core of the utility model lies in providing a folding hanging ladder, as shown in fig. 2, which is a partial structure schematic diagram of the folding hanging ladder of the utility model, and the drawing shows two states of folding and using at the same time; FIG. 3 is a schematic top view of the structure of FIG. 2; the folding hanging ladder comprises a hanging frame 1 and a supporting frame 2, wherein the hanging frame 1 and the supporting frame 2 are both of frame-shaped structures and are rectangular; set up a plurality of footboards 3 between stores pylon 1 and the support frame 2, what footboard 3 articulated respectively in stores pylon 1 and support frame 2 forms parallelogram mechanism, stores pylon 1 sets up one respectively with support frame 2, and footboard 3 then sets up a plurality ofly, and each footboard 3 mutual parallel arrangement, consequently can form a plurality of equal quadrangle mechanisms.

The widths of the hanging rack 1 and the supporting rack 2 are equal, the width of the pedal 3 is smaller than the widths of the hanging rack 1 and the supporting rack 2, and the pedal 3 can enter the frames of the hanging rack 1 and the supporting rack 2; each pedal 3 is provided with four hinged shafts, two hinged shafts of each pedal 3 are connected to the hanging rack 1 in a collinear way, the other two hinged shafts are connected to the supporting frame 2 in a collinear way, and the pedals 3 can rotate relative to the hanging rack 1 and the supporting frame 2; under fold condition stores pylon 1 can laminate with support frame 2, holistic thickness is stores pylon 1 and support frame 2's thickness sum.

In the unfolding state, the hanging frame 1 and the support frame 2 are separated from each other and are not attached to each other, and the bottom ends of the hanging frame 1 and the support frame 2 can be in contact with the ground to play a supporting role; at this time, the step 3 is unfolded, and the step 3 is approximately horizontal, so that a person can step on the step for providing stable support for the person.

The top of stores pylon 1 sets up couple 4, and couple 4 plays the effect of hanging, and under the user state, couple 4 can hook onto supporting platform, provides ascending holding power to the top of stores pylon 1, plays the supporting role.

The utility model discloses a footboard 3 of folding string ladder adopts articulated connection form, footboard 3 changes along with rotating with stores pylon 1 and support frame 2's contained angle, holistic thickness is irrelevant with the width of footboard self under fold condition, thickness only is stores pylon 1 and support frame 2's thickness sum, consequently footboard 3 can set up great width, stores pylon 1 and support frame 2 remain the parallel state throughout, footboard 3's width is big more, interval between stores pylon 1 and the support frame 2 is big more when expanding, footboard 3's width makes things convenient for personnel to stand under the expansion state more and steps on, provide more stable support.

On the basis of the scheme, the utility model is provided with the triangular support rib plate 31 on the lower surface of the pedal 3, the surface of the support rib plate 31 is vertical to the upper surface of the pedal 3, and the support rib plate 31 is hinged with the hanging rack 1 through the connecting shaft; by arranging the supporting rib plate 31, the upper surface of the pedal 3 is parallel to the supporting frame 2 when the hanging frame 1 and the supporting frame 2 are attached.

In order to facilitate treading, the upper surface of the pedal 3 is provided with anti-skid lugs to increase the friction force with the foot.

On the basis of any one of the above technical scheme and the mutual combination thereof, the utility model discloses an inner chamber of couple 4 includes entrance section 41, linkage segment 42 and spacing section 43, as shown in fig. 4, for the structural schematic of couple 4, entrance section 41 communicates with the external world, entrance section 41, linkage segment 42 and spacing section 43 are straight structures, form the dog-ear between entrance section 41 and linkage segment 42, linkage segment 42 and spacing section 43 respectively, the jib gets into from entrance section 41 earlier when hanging, the turn gets into linkage segment 42, the turn gets into spacing section 43 again, the jib finally is located within spacing section 43; the hook 4 is provided with two hook structures, when the transportation platform needs to be adjusted to the wheels to work off the ground, the hanging ladder hung on the platform can not slide out due to the two hooks and can only ascend along with the leveling, although the working angle of the ladder is changed, the ladder hook can not be separated from the hanging rack, the difficulty of separating the hook from the hanging rod is increased, and the danger caused when people go up the ladder without attention is avoided.

Preferably, the width of the inlet section 41, the connecting section 42 and the limiting section 43 is equal; the folding angle between the inlet section 41 and the connecting section 42 and between the connecting section 42 and the limiting section 43 is not more than 150 degrees, and the hook can be separated easily due to the excessively large angle, so that unnecessary risks are caused.

The utility model discloses a folding ladder of hanging still includes locking device 5, as shown in fig. 5, for locking device 5's structural schematic diagram, locking device 5 is including fixed cover 51, movable pin 52 and spring 53, fixed cover 51 is fixed on stores pylon 1 or support frame 2, the inside cavity of fixed cover 51, movable pin 52 and spring 53 are installed within fixed cover 51, movable pin 52 is outwards ejecting by spring 53, correspond to insert in the through-hole of seting up on stores pylon 1 and the support frame 2, play spacing effect when stores pylon 1 and support frame 2 laminate each other, convenient folding transportation.
