Description
Technical Field
The utility model relates to a ladder is with flexible lower margin wheelset that props.
Background
The large ladder needs to be carried by a plurality of people due to the fact that the large ladder is too large in weight and size and inconvenient to move, the supporting legs of the large ladder on the market adopt the rolling wheels, the foot brakes are arranged beside the rolling wheels so as to fix the trundles during climbing, and the large ladder has the defect that the trundles roll and the ladder is displaced when an operator climbs the ladder in case that the foot brakes are not tightly braked.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a ladder is with flexible supporting lower margin wheelset.
The utility model discloses technical scheme as follows: the utility model provides a ladder is with flexible rag wheelset that props, sets up flexible module and the pedal pole of transverse connection between flexible module at the ladder pole lower extreme including the symmetry, flexible module includes the telescopic link, slides and sets up the plastics slider on the telescopic link, and the cover is established and is established the assembly cover outside the plastics slider and set up the universal wheel at the telescopic link lower extreme, the assembly cover is articulated with the one end of bevel arm, the other end and the pedal pole of bevel arm are articulated, the telescopic link lower extreme is articulated with locking arm one end, the locking arm other end is articulated with the middle fulcrum of bevel arm through hexagon socket head cap screw, the locking arm is equipped with fender position axle sleeve with the articulated department of telescopic link lower extreme, the telescopic link upper end.
Specifically, the method comprises the following steps: the plastic sliding block is provided with a positioning pin, and the assembly sleeve is provided with a positioning hole matched with the positioning pin.
Specifically, the method comprises the following steps: the outer wall of the assembly sleeve is provided with a ladder rod assembly hole.
The beneficial effects of the utility model reside in that: whole flexible lower margin wheelset that props passes through the pilot hole assembly on the ladder pole, when the ladder needs the climbing, the fixed stay foot of ladder props the ground, whole flexible module is the contraction status, when the ladder needs to remove, then the foot is stepped on the foot rest lever, foot rest lever drive bevel arm rotates downwards, the middle fulcrum drive locking arm of bevel arm makes the telescopic link extension, when foot rest lever and fender position axle sleeve counterbalance, whole extending structure is firm, the truckle contacts to the ground, can remove the ladder, whole flexible ground truckle group structural design is reasonable, the assembly is simple, relative foot brake formula truckle group, high safety factor.
