Description
Technical field
The utility model relates to a kind of escaping tool, particularly a kind of escape folding ladder be arranged on escape scuttle limit.
Background technology
Along with people are to the reinforcement day by day of awareness of the importance of fire prevention, how when fire arrives, can carry out escaping in time and conveniently by life preserver be the problem of current house safety escape primary study.The escaping tool majority of current use is tightrope ladder, and its Problems existing is that tightrope is firm not, and amplitude of fluctuation is large, and use dangerous, particularly women, children and the elderly also security incident can occur in climbing process.Next is that the mode of building stair is outside window escaped, and its Problems existing is that cost of production is high, and installation is inconvenient, takes up room large, also brings antitheft problem simultaneously.For this reason, many manufacturers and knowledgeable people have carried out R and D, but not yet have comparatively ideal product to emerge so far.
Summary of the invention
For overcoming the problems referred to above that existing escaping tool exists, the purpose of this utility model is to provide a kind of simple and reasonable, swift and convenient to operate, supporting capacity is good, folding volume is little, safe and reliable escape folding ladder.
The utility model solves the technical scheme that its technical problem adopts, it comprises fixed ladder bar, mobile ladder bar, somely steps on pipe, described fixed ladder bar is fixed on metope by terraced bar holder, fixed ladder bar is provided with relative notch with mobile ladder bar, the two ends correspondence of stepping on pipe is hinged on the notch of fixed ladder bar and mobile ladder bar, step on pipe and the hinged end face of fixed ladder bar be provided with ramp or upper arc surface and under face directly, step on pipe and be provided with the hinged end face of mobile ladder bar and face directly and lower inclined plane or lower arc surface; When ladder is opened, the bottom of mobile ladder bar and earth surface, face directly under stepping on pipe and contact with the pocket bottom of fixed ladder bar, step on pipe on face directly and contact with the pocket bottom of mobile ladder bar.
Further scheme of the present utility model, the top of described mobile ladder bar is provided with antihunting mechanism, this mechanism comprises A-frame, carrier base, limit base, A-frame top is connected on mobile ladder bar by limit base, and the both sides of A-frame are arranged on the carrier base fixing with metope rotationally.
Further scheme of the present utility model, described fixed ladder bar is provided with movable locking plate, and mobile ladder bar is fixed with lock pin, and locking plate is provided with the latch hook matched with lock pin, and when ladder folds, locking plate pins lock pin by latch hook.
Further scheme of the present utility model, is provided with safety barrier between described fixed ladder bar and mobile ladder bar, and safety barrier can fold with mobile ladder bar.
Further scheme of the present utility model, described terraced bar holder is provided with symmetrical nut draw-in groove, and fixed ladder bar is arranged on the nut draw-in groove of terraced bar holder by the cooperation of screw and nut.
Adopt after said structure, have following advantage and effect compared with the prior art: one is ladder collapses abut against on metope with coordinating of lock pin by latch hook when not using, folding volume and take up room little; Operate latch hook at escape window during use, latch hook and lock pin are departed from, and mobile ladder bar automatically opens ladder under Gravitative Loads, down can depart from scene of fire along ladder, simple to operate, easy to use.Two is that can only can operate latch hook on escape window, cannot operate latch hook on ground, theftproof performance is good because movable locking plate is arranged on the top of ladder.Three is because antihunting mechanism is arranged on escape window limit, not only can prevent ladder from swinging, and improves ladder stabilizer, and can as the one climbing transition instrument between escape window to ladder.Four is owing to being provided with safety barrier between fixed ladder bar and mobile ladder bar, can ensure not swing back in climbing process, ensures that climbing is safe and reliable.
