Personnel are frequently necessary to use double ladder as ascending tool.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of fixation, stores the double ladder of conveniently moving.
In order to solve the above-mentioned technical problem, the utility model includes left ladder legs and right ladder legs, in left ladder leg
The lower end in portion is hinged with the first conversion pedestal, and the second conversion pedestal, the first conversion pedestal are hinged with the lower end of right ladder legs
Pedestal is changed into L-type with second, and the first conversion pedestal includes the first plate body and the second plate body, and the first plate body is cut with scissors with left ladder legs
Connect, the second plate body is in the left end of left ladder legs, the second conversion pedestal includes the 3rd plate body and the 4th plate body, the 3rd plate body with
Right ladder legs are hinged, and the 4th plate body is in the right-hand member of right ladder legs, are filled on the second plate body and the 4th plate body provided with roller
Put, anti-skidding pad is provided with the bottom of the first plate body and the bottom of the 3rd plate body.
As further improvement of the utility model, the first connection bump is provided with the first plate body, in the 3rd plate body
The second connection bump is provided with, the first connection bump is provided with the connecting rope that can be connected with the second connection bump.
As further improvement of the utility model, the roller devices include fix bar, and fix bar is provided with universal wheel,
It can be close to by being provided with one provided with a brake block consistent with universal camber of wheels in fix bar, on the brake block
The button switch of universal wheel.
When left ladder legs and right ladder legs are stretched out make double ladder in running order when, by the first conversion pedestal
3rd plate body of the first plate body and the second conversion pedestal turns to lower end, anti-skidding pad is contacted with ground so that double ladder is fixed
Firmly.Folded when by left ladder legs and right ladder legs when being stored, the first plate body of rotation and the 3rd plate body make the second plate
Body and the 4th plate body are in lower end, so can easily be moved by universal wheel, while being connected convex with second by connecting rope
Connection is played, the first connection bump and the second connection bump is linked together, left ladder leg when double ladder is moved after storing is prevented
Portion and right ladder legs are separated
In summary, the utility model has the advantages that fixation, storage conveniently moving.
