Detailed description of the invention
As shown in Figures 1 to 4, the folding ladder that the utility model proposes, comprising: bracing frame, the top pedal being articulated with bracing frame top, the hinged side pedal with bracing frame side.
Bracing frame by the first support, the second support is hinged forms, first support comprises two the first pillars 1 side by side, second support comprises two the second pillars 2 side by side, two first pillar 1 coordination hinges are outside the second support 2, two first pillar 1 lower ends are laterally provided with the first horizontal stripe 3, and two second pillar 2 lower ends are laterally provided with the second horizontal stripe 4.The pin joint of bracing frame is near upper end, and when ladder launches, foot of ladder aperture is comparatively large, ensures safety when ladder uses.
Top pedal, top pedal is made up of by hinge 6 is hinged two adjacent thick pedals 5, two thick pedal 5 bottom surfaces are located at by hinge 6, pedal one end, top is articulated with between two the first pillars 1, the other end is articulated with two second pillar 2 tops by hinge 6, the difference in height of first and second support coordinates with top pedal thickness, ensures that ladder struts rear top pedal and is horizontal.Top board metal support is also provided with bottom the pedal of top, top board metal support is made up of two carriages 7 wrapped up respectively bottom two thick pedals 5, the side plate abutting end of two carriages 7 is articulated and connected, the other end is articulated with between thick pedal 5 and bracing frame top, and the base plate of carriage 7 is made up of the even laterally bonding jumper 8 be located between biside plate.
During use, two thick pedals 5 and top board metal support are fully expanded with bracing frame top, and the adjacent surface of thick pedal 5 is tightly fitted, because the length of two thick pedals 5 and top board metal support is fixed value, now, the gravity be pressed on two thick pedals 5 is larger, and the softened pressure in bracing frame bottom is larger, the tensile force of two thick pedals 5 and top board metal support is larger, and the structure of top pedal is more steady.Strengthened the bearing capacity on ladder top by top board metal support, and ensure the stability after ladder expansion.
Side pedal, side pedal is articulated with the connection strap 9 between adjacent folded layers lateral surface by least two foldings layer, two ends, the pedal 11 that foldable layer comprises two edge strips 10 side by side and is fixed between two edges, two edges 10 one end is bending and curved end is articulated with two first pillar 1 lateral surfaces upward respectively, pedal 11 is fixed between the vertical end of two edges 10, pedal 11 is provided with gap with the curved end of two edges 10, close foldable layer time, the radian of edge strip 10 curved end coordinates pedal 11 to fit completely the first pillar 1.First pillar 1 lateral surface is provided with the positioning boss 12 coordinated with each edge strip 10 curved end horizontal level, positioning boss 12 is played a supporting role, during unfolded layer, when the vertical end of edge strip 10 is horizontal, the curved edges of edge strip 10 abuts with positioning boss 12 just.
Edge strip 10 is metal edge strip, is evenly laterally provided with the metallic support bar 13 being positioned at pedal bottom surface between the two edges 10 of foldable layer, the arranging of metallic support bar 13 can strengthen side pedal by force intensity, improve the application life of ladder.The two edges 10 of foldable layer is protruding upward and form detent with pedal 11, and rotary folding is stacked to pedal 11 and the first pillar 1 is fitted, and two first pillars 1 are located in detent, make folding after ladder structure compact stable, not easily rock when moving ladder and scatter.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
