Abstract
The utility model provides a climbing ladder with a brake. The climbing ladder comprises two ladder frames, wherein each ladder frame comprises two support legs; multiple stages of ladder pedals are arranged horizontally between the two support legs; the tops of the two ladder frames are connected with each other through a revolving shaft; the middle parts of the two ladder frames are connected with a pull rod; a connecting rod is arranged between two stages of ladder pedals at the bottom of each ladder frame; the upper end of each connecting rod is fixed, and the lower end of each connecting rod passes through each bottommost ladder pedal; a runner is arranged at the tail end of each connecting rod; a part of each connecting rod which is positioned between the corresponding two stages of ladder pedals is sleeved with a spring; and a gap is reserved between each bottommost ladder pedal and each corresponding runner. The climbing ladder is provided with a bottom spring extension and contraction structure, so that the climbing ladder can be moved conveniently; and moreover, braking is realized by using the gravity of a human body, so that the climbing ladder is safe and reliable, and has high practicability.
Description
Technical field
The utility model relates to a kind of ladder, is specifically related to a kind of step ladder with brake.
Background technology
In order to ensure user of service's safety, carry, usually adopt reverse V-shaped ladder when sort articles need to be ascended a height, the both sides ladder is at an angle to each other during expansion, and is more stable when supporting on the ground, and simultaneously, ladder structure is designed to collapsible, is convenient for carrying and carries.But because ladder adopts metal to make, weight is larger, when the mobile operating place, needs the manpower transport, wastes time and energy.
Summary of the invention
Defective for existing ladder difficult, the utility model provides a kind of step ladder with brake, its structure comprises two ladders, each ladder comprises two supporting legs, be horizontally disposed with multistage stile between two supporting legs, described two ladder tops are connected by rotating shaft, the middle part is connected with pull bar, be provided with connecting rod between the two-stage stile of bottom, the connecting rod upper end is fixing, the lower end runs through nethermost stile and end is equipped with runner, the part of connecting rod between the two-stage stile is set with spring, leaves the gap between nethermost stile and the runner.
As preferably, described runner adopts Universal castor, random conversion direction when ladder is moved.
As preferably, described stile adopts the pedal stile, increases the user of service and rides comfortableness and stationarity on stile.
During use, ladder is launched to both sides along rotating shaft, expanded angle is by the pull bar length restriction, and the user of service steps on stile, and under people's Action of Gravity Field, the pedal Compress Spring of ladder bottom stretches out a segment distance downwards, and ladder foot contacts with ground and makes it firm quiet vertical; When needs moved, because the ladder own wt is lighter, ladder bounced back under the active force of Compress Spring, and connecting rod is then stretched outside the ladder foot relatively, and runner is landed, and directly promotes ladder and can realize that it moves.
The beneficial effects of the utility model are according to the narration of such scheme as can be known: this step ladder is provided with the telescopic spring structure of bottom, can conveniently move, and utilize personal gravity to realize that brake uses, and is safe and reliable, practical.
