Abstract
The utility model relates to a steel movable folding ladder which is composed of a front and a rear brackets and a plurality of pedals. The utility model is characterized in that the circumference of the upper pedal (3) on the uppermost layer is folded into an edge downwards. The front part of the upper pedal is positioned between two legs of the front bracket (1) and is hinged on the inner sides of the two legs of the front bracket. The inner surfaces of both sides of the middle part of the upper pedal are respectively hinged with a connecting rod (4) hinged with the rear bracket respectively (2). The utility model has the advantages of simplicity, flexibility, high safety, slippage prevention, movement prevention, etc. The utility model can be widely used for climbing and taking objects in various occasions in daily life.
Description
The utility model relates to ladder, the movable folding ladder of particularly a kind of steel.
Traditional folding ladder is formed by front and back support is hinged, and it is pedaled plate and is made of the cross-lining that is positioned on the front and back support, and the folding ladder of this structure is not owing to there is self-locking device, and the area of pedaling plate is little, so the people station is unstable thereon, and is very dangerous during use.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose the movable folding ladder of a kind of steel esy to use, safe and reliable.
At the foregoing invention purpose, the utility model adopts following technical scheme: the movable folding ladder of a kind of steel, after-poppet that fore-stock that is made of two legs and two legs constitute and multilayer are pedaled plate and are formed, wherein, the head of fore-stock and after-poppet is hinged, special character of the present utility model be described the top one deck upper pedal board 3 around play the limit down, the front portion of this upper pedal board is between fore-stock 1 two legs and be hinged on the inboard of the two legs of fore-stock, both sides, upper pedal board middle part each articulated hinged with the after-poppet two legs respectively connecting rod 4 of inner face.
In such scheme, described the top second layer pedal plate can by two one connection angle bar 6 that is hinged on fore-stock 1 two legs inboard respectively be fixed in two panels 5 that are connected above the angle bar 6 and form, the hinged inside that connects angle bar 6 other ends connecting rod 7, the two legs hinged inside of connecting rod 7 and after-poppet 2.
In such scheme, described remainder layer is pedaled plate and is made up of two one connecting rod that is hinged on fore-stock 1 two legs inboard respectively 10 and the panels 11 fixed above two connecting rods 10, the other end of connecting rod 10 with reperuse 8 one hinged, the pin joint that reperuse 8 other end and top one deck are pedaled plate and connecting rod is hinged.
The utility model can be divided into two to nine various levels, when launching to use, only need one to draw, connect angle bar and connecting rod and then produce self-locking, so just can be upper and lower easily and stand on any one deck operation of ladder, the operation back desire that finishes is folding, only needs gently upper pedal board one top can be closed up, after closing up, front and back support is parastate.The utlity model has easy to usely, flexible, safe and reliable, anti-skidding anti-move, advantage such as light attractive in appearance, it can be widely used in to ascend a height under the various occasions in the daily life gets the usefulness of thing.
Below in conjunction with three layers of terraced embodiment shown in the accompanying drawing, describe the utility model in detail.
Fig. 1 is a front view
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a folding back schematic diagram.
