Further, marking time for one of ladder body upper part is equipped with workbench, and the workbench includes two
Strut and landing slab, two strut one end and mark time hinged, and the other end is hinged with landing slab, and the landing slab other end passes through card slot card
It is set on single order marks time.
The advantageous effect of utility model
A kind of fire-fighting retractable herringbone ladder comprising two ladder ontologies connected by oscillating bearing at top, Mei Gesuo
It includes that two multi-joint telescoping supporting beams, multiple both ends are stepped on retractable support beam by what clip was fixedly mounted respectively to state ladder ontology
Plate and the balancing pole for being fixedly arranged on retractable support beam bottom portion often save and install a pedal on retractable support beam, in this way, terraced first
Son when not in use, can be shunk, not only facilitate storage, but also easy to carry, and two ladder ontologies are used at top and closed
Bearings are hinged, keep the connection between two ladder ontologies reliable, the upper part of two multi-joint telescoping supporting beams
It is not hinged with stable supporting rod, support boom end is stablized in the stable supporting rod other end end on the ladder ontology of the other side
It is hinged, when ladder in use, two ladder ontologies are supported, stablizes supporting rod and also just strut, be connected to two ladder sheets
Between body, firm effect is played, is generated between preventing ladder from causing two ladder ontologies since heavy burden is excessive when in use opposite
Movement, increases the safety used, when ladder is shunk, stablizes supporting rod due to being hinged at middle part, can also be folded
It shrinks, facilitates storage and carrying, stable pin is installed with respectively in the interior outside of two retractable support beams on the balancing pole
Set increases the contact area with ground during such ladder use, more solid and reliable.
Traveling wheel is installed on the balancing pole, it, can be with by traveling wheel after ladder is shunk when ladder needs mobile
It slides on the ground, it is more time saving and energy saving, save the time for rescue.
It is equipped on the marking time of bottom with the bandage ladder for adjusting lock, it, can be with during not using or moving
By lockking telescopic section with the bandage for adjusting lock, prevents it from arbitrarily stretching, facilitate storage or movement and compare peace
Entirely.
Hook is hinged at the top of ladder ontology, when ladder when not in use, ladder can be suspended on wall, facilitate storage,
Save space.
Marking time for one of ladder body upper part is equipped with workbench, and the workbench includes two struts and puts down
Platen, two strut one end and marks time hinged, and the other end is hinged with landing slab, and the landing slab other end is set to upper one by card slot card
On rank is marked time, so in use, landing slab can be opened, it above can be with place tool.
