SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a step on bench ascends a height to solve current chevron shape and ascend a height and step on the mode that bench frictional force is fixed and be not stable enough, the ladder takes place to slide when ascending a height and takes place danger easily, the mode of connecting through simple and easy connecting rod makes can only open and shut fixed angle between two ladders, and current chevron shape ascends a height and steps on the problem that the bench does not have protector.
The utility model discloses a realize through following technical scheme:
a climbing footstool comprises a left ladder and a right ladder which are hinged with each other;
sliding grooves are formed in the two side faces of the left ladder and the two side faces of the right ladder along the length direction;
a plurality of first threaded holes are formed in the bottom surface of the sliding groove;
a sliding block is arranged in the sliding groove, and a second threaded hole which is communicated with the sliding block and corresponds to the first threaded hole is formed in the sliding block;
the first threaded hole and the second threaded hole are in threaded connection through a first screw;
a rotating rod perpendicular to the upper surface of the sliding block is arranged on the sliding block, a bearing is sleeved on the rotating rod, and a limiting stop lever is arranged at the top end of the rotating rod;
a sleeve is fixed on the outer side surface of the bearing;
the fixed connecting rod is in inserting fit with the sleeve;
two ends of the fixed connecting rod are respectively provided with a guardrail.
The length of the left ladder is the same as that of the right ladder.
The sliding groove is a dovetail groove, and the sliding block is a dovetail-shaped sliding block matched with the sliding groove.
The fixed connecting rod is provided with a plurality of first positioning holes at equal intervals along the length direction, and the second screw rod is matched with the first positioning holes;
the two ends of the fixed connecting rod are provided with the guardrails.
And an included angle between the axial center line of the guardrail and the axial center line of the fixed connecting rod is 60 degrees.
The utility model has the advantages that;
this technical scheme is through fixed connecting rod and telescopic grafting cooperation structure, can be in order to adjust the angle that opens and shuts of left ladder and right ladder, can accomplish the back again through fixed connecting rod with left ladder and right ladder fixed connection together, left ladder and right ladder take place to slide when preventing to ascend a height, and the guardrail of installing at fixed connecting rod both ends can form the protection to the user of ascending a height, effectively prevents that it from falling from left ladder or right ladder.
