Abstract
The utility model discloses a parallelogram folding ladder which comprises a first column (1), a second column (2), a third column (3) and a fourth column (4), wherein the first column (1) is hinged with the top end of the third column (3), the second column (2) is hinged with the top end of the fourth column (4), at least two layers of front detachable horizontal footboards (5) are arranged between the first column (1) and the second column (2), and at least two layers of rear detachable horizontal footboards (6) are arranged between the third column (3) and the fourth column (4). The parallelogram folding ladder is characterized in that stabilizing devices are respectively arranged between the first column (1) and the second column (2) and between the third column (3) and the fourth column (4). The parallelogram folding ladder is simple in structure, not only can be arbitrarily folded along the length, width and height directions, but also has good stability, and the safety during the use process is improved.
Description
Technical field
The utility model relates to a kind of ladder, relates in particular to a kind of parallelogram folding ladder.
Background technology
Only width is collapsible for existing pair of ladder, and length can not fold with height.Volume is big, carries inconvenience.The patent No. is the Chinese utility model patent foldable ladder of ZL89208874.5, though this ladder length is all collapsible, easy to carry; In use, because the unstability of parallelogram can deform, the people can throw from ladder; Be absolutely unsafe, so use value is not high.
The utility model content
The utility model provides a kind of safe and reliable and all folding parallelogram folding ladder of length direction in order to solve weak point of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the parallelogram folding ladder; Comprise first column 1, second column 2, the 3rd column 3 and the 4th column 4; First column 1 and the 3rd column 3 tops are hinged, and second column 2 and the 4th column 4 tops are hinged, are provided with two-layer at least dismountable preceding horizontal pedal 5 between first column 1 and second column 2; Be provided with two-layer at least dismountable back horizontal pedal 6 between the 3rd column 3 and the 4th column 4, be provided with the stability maintenance device between said first column 1 and second column 2 and between the 3rd column 3 and the 4th column 4.
Be connected with stopping means between said first column 1 and the 3rd column 3 middle parts and between the middle part of second column 2 and the 4th column 4, said stopping means is a gag lever post 11, and gag lever post 11 middle parts are provided with first hinge 13 that is used to fold.
Said stability maintenance device comprises that upper end that the middle part is provided with first hound 7 of second hinge 14, second hound 8, the 3rd hound 9 and the 4th hound 10, the first hounds 7, second hound 8, the 3rd hound 9 and the 4th hound 10 is hinged with second column 2, first column 1, the 4th column 4 and the 3rd column 3 respectively; The lower end of first hound 7, second hound 8, the 3rd hound 9 and the 4th hound 10 is connected through U type latch 15 with the 4th column 4 with first column 1, second column 2, the 3rd column 3 respectively.
Said first column 1, second column 2, the 3rd column 3 and the 4th column 4 middle parts are respectively equipped with the 3rd hinge 16, the three hinges 16 places that are used to fold and are provided with L type latch 17.
Said first column 1, second column 2, the 3rd column 3 or the 4th column 4 tops are provided with vertical rod 18, and vertical rod 18 is provided with hook 19 and strong magnets 20.
Said first column 1, second column 2, the 3rd column 3 and the 4th column 4 lower ends are respectively equipped with leg 21.
Adopt technique scheme; Because parallelogram has unstability, triangle has stable characteristics; First hound, second hound, the 3rd hound and the 4th hound play the effect of good stable property, and the length of ladder is all collapsible, and is easy to carry.Stopping means is a gag lever post, plays the effect that prevents that ladder from slipping.U type latch is convenient to dismounting, and first hinge, second hinge and the 3rd hinge all play folding effect, and L type latch plays four root posts that launch are in stable state, extracts L type latch out and just can fold by column.Hook is used to hang the sack of splendid attire instrument, and strong magnets is used to adsorb the irony instrument, is convenient to the operator and uses.Leg plays the effect that increases by four root posts and contact area of ground.
The utility model is simple in structure, not only can be folding arbitrarily on the length direction, and have good stable property, and improve the safety in the use.
