Abstract
The utility model discloses a novel safe herringbone ladder which consists of a pedal, ladder rack groups and pedal rods, wherein corresponding screw holes are reserved on the opposite inner side surfaces of the rod bodies of the ladder rack groups; the pedal rods are inserted into the corresponding screw holes; two ladder rack groups are installed and form a herringbone ladder together with the lower part of the pedal; a row of insertion holes are reserved on the outer side surface of each rod body of the ladder rack groups; U-shaped stabilizing rods are inserted into the insertion holes of the same row of opposite ladder rack groups; an anti-skidding sleeve is sleeved at the bottom of each rod body of the ladder rack groups; and the bottom of each anti-skidding sleeve is connected with an anti-tilting pad. By adopting the structure, the ladder rack groups of the herringbone ladder are opened according to a proper amplitude as required, and then the U-shaped stabilizing rods are inserted into the corresponding insertion holes of the same row; as an anti-skidding sleeve and an anti-tilting pad are sleeved at the bottom of each rod body of the ladder rack groups, the contact area between the herringbone ladder and the ground can be increased, and the friction force is enhanced; and because of the structure, a stable framework can be provided for the herringbone ladder.
Description
Technical field
The utility model relates to a kind of new type of safe double ladder of high stability.
Background technology
Usually all be connected with a chain between the double ladder ladder commonly used at present, avoid too launching between the ladder, cause tilting to fall down; But the safeguard measure itself such through chain has certain defective; Chain is shaken easily, is not very stable, especially after the people stands in high point; Cause crank easily, a kind of tumbledown sensation is arranged; Usually the anti-pad that turns over also is equipped with in the bottom of ladder, but the anti-pad that turns over of this type is generally simple in structure, and practicality is not very strong, can not play good skidproof effect.
The utility model content
The technical problem that the utility model will solve provides a kind of new type of safe double ladder of high stability.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of new type of safe double ladder is made up of pedal, ladder group and treadle, and ladder group body of rod medial surface in opposite directions leaves corresponding screw; Be inserted with treadle in the corresponding screw; Two groups of ladder assemblings are formed double ladder with the below of pedal, and the lateral surface of the ladder group body of rod all leaves a socket hole, is inserted with the U-shaped stabiliser bar in the jack of ladder group in opposite directions with row; The bottom of the ladder group body of rod is with anti-sliding sleeve, and the bottom of anti-sliding sleeve is connected with the anti-pad that turns over.
Adopt after the such structure of the utility model; Launch suitable amplitude as required between the ladder group of double ladder, the U-shaped stabiliser bar is inserted in accordingly with among the socket hole again, the bottom of the ladder group body of rod is with anti-sliding sleeve and the anti-pad that turns over; Can increase the contact area on double ladder and ground; Strengthen frictional force, such structure can provide very stable framework for double ladder, the people is stood in do not have a kind of tumbledown sensation on the pedal.
