Background technology
In daily production and life, often can use ladder ascend a height, use more Foldable double-sides double ladder at present.Foldable double-sides double ladder comprises left and right pedal, left and right ladder leg, ladder step, left and right pedal correspondence is fixed on the terraced leg in left and right, connected by hinge between the pedal of left and right, ladder step is evenly fixed on the terraced leg in left and right, the collapsible pull bar of corresponding connection between the terraced leg in left and right, about during use, terraced leg is separated from each other and evens up collapsible pull bar, and about when not using, terraced leg and collapsible pull bar fold mutually.But existing Foldable double-sides double ladder in use has the following disadvantages: one is because hinge need have rotation space, therefore size is folded larger, simultaneously due to exist between the pedal of hinge through left and right tong may, have during use and jam a finger or the risk of skin.Two is that bonding strength is poor, supporting capacity is low because hinge easily produces loosening.Three is that assembly process is many, and production efficiency is low.For this reason, many manufacturers and knowledgeable people have carried out R and D, but not yet have comparatively ideal product to emerge so far.
Summary of the invention
For overcoming the problems referred to above that existing Foldable '*' shape ladder exists, the purpose of this utility model be to provide a kind of simple and reasonable, production and processing facilitates, be connected firmly, the Foldable double-sides double ladder that safe and reliable, supporting capacity good, efficiency of assembling is high.
The utility model solves the technical scheme that its technical problem adopts, it comprises pedal, left terraced leg, right terraced leg, ladder step, ladder step is evenly fixed on left terraced leg and right terraced leg, the top correspondence of described left terraced leg is fixed with the first junction plate and the second junction plate, the top correspondence of right terraced leg is fixed with the 3rd junction plate and the 4th junction plate, and on first to fourth junction plate, correspondence is provided with the connecting axle be connected as a single entity; Described pedal is provided with the first locating slot, the second hinged groove, the 3rd draw-in groove and the 4th draw-in groove that run through bottom monoblock pedal, the connecting axle of the first junction plate coordinates with the notch of the first locating slot locates, connecting axle correspondence on second junction plate to be inserted in the second hinged groove and to be hinged, and the connecting axle correspondence of the 3rd junction plate and the 4th junction plate to be inserted in the 3rd draw-in groove and the 4th draw-in groove and to interfix.
Further scheme of the present utility model, the both sides correspondence of described pedal is fixed with left and right protecting cover, and left and right protecting cover is provided with the blocking that matches with the first locating slot, the second hinged groove, the 3rd draw-in groove and the 4th draw-in groove two ends and props up connecting axle.
Further scheme of the present utility model, the upper surface of described pedal is provided with some anti-slip tanks.
Further scheme of the present utility model, described pedal, left terraced leg, right terraced leg, ladder step and first to fourth junction plate are made up of aluminium alloy extrusions.
After adopting said structure, there are following advantage and effect compared with the prior art: one is the improvement left terraced leg and the syndeton between right terraced leg and pedal, left terraced leg by the connecting axle on the second junction plate and the second hinged groove on pedal hinged, the notch of the connecting axle on the first junction plate and the first locating slot is located, right terraced leg is inserted in the third and fourth draw-in groove by the connecting axle correspondence of the third and fourth junction plate and fixes with pedal, jam a finger when eliminating use or the hidden danger of skin, safe and reliable.Two is because left terraced leg and right terraced leg are connected on one piece of pedal, very close to each other each other, is connected firmly, and supporting capacity is strong, good stability.Three is because critical piece is all made with aluminium alloy extrusions, and production and processing is convenient, and operating efficiency is high, constant product quality.Four is because the upper surface of pedal is provided with some anti-slip tanks, substantially increases non-skid property.
