Abstract
The utility model relates to a portable climbing ladder which comprises ladder frame rods arranged in a bilateral symmetric manner, a plurality of ladder steps with two ends hinged on the ladder frame rods, insertion heads arranged at one ends of the ladder frame rods and insertion barrels arranged at the other ends of the ladder frame rods, wherein the insertion heads on the ladder frame rods are provided with insertion head bolt rod holes; the insertion barrels on the ladder frame rods are provided with insertion barrel bolt rod holes; bolt rods are inserted into the insertion head bolt rod holes and the insertion barrel bolt rod holes respectively, so that the ladder can be doubled in length. The ladder is convenient to dismount; during transportation, the bolt rods are dismounted, and the two ladder frame rods of the ladder can be close to each other through the hinged ladder steps, so that the size of the ladder is reduced and the ladder can be conveniently carried and transported.
Description
Technical field
The utility model relates to a kind of portable cat ladder.
Background technology
In present electric power and communication construction, much need ladder to install or maintenance activity, many times need the ladder grown very much, and in transportation because ladder is grown up and mostly is tiltedly to comply with danger close on wagon box very much; Useful folding ladder, but existing folding ladder or structure of telescopic ladder are complicated, easily break down and are not durable, does not have the ladder of safe, simple in structure, firm and durable easy to carry yet.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of be convenient for carrying transportation can fold the cat ladder with continued access.
The utility model adopts following technical scheme:
The utility model comprises that the terraced frame bar, the two ends that are symmetrical set are hinged at a plurality of steps on terraced frame bar, are arranged on the plug of terraced frame bar one end and the insertion tube that is arranged on the terraced frame bar other end, plug on described terraced frame bar is provided with plug tightening latch hole, insertion tube on described terraced frame bar is provided with insertion tube tightening latch hole, in described plug tightening latch hole and insertion tube tightening latch hole, is plugged with respectively tightening latch.
Described step is hinged by fixed axis and the terraced frame bar being set on otic placode.
Described tightening latch two ends are provided with dismountable clamp nut.
The utility model good effect is as follows:
The utility model in use, is opened folding terraced frame bar, and tightening latch is inserted respectively in the plug tightening latch hole and insertion tube tightening latch hole on terraced frame bar, and two tightening latches and terraced frame bar form firm framework, can not tilt, and the step being now hinged will be firm; When construction single-unit the inadequate length of ladder time, two ladders can be continued, the plug of a ladder is inserted in the insertion tube of another ladder, now the plug tightening latch hole of two ladders and insertion tube tightening latch hole are overlapping, with tightening latch cross-under, fix again, the plug tightening latch hole at ladder two ends now and insertion tube tightening latch hole are fixed with tightening latch, and especially the clamp nut on tightening latch can allow ladder more firm; Ladder will double like this, and convenient disassembly, during transportation, is pulled down tightening latch, and the step of hinge can be close by two of ladder terraced frame bars, reduces the volume of ladder, convenient carrying and transportation.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 4 is the terraced splicing structure schematic diagram of the utility model two;
In the accompanying drawings: 1 terraced frame bar, 2 steps, 3 plugs, 31 plug tightening latch holes, 4 insertion tubes, 41 insertion tube tightening latch holes, 5 tightening latches, 6 otic placodes, 7 fixed axis, 8 clamp nuts.
The specific embodiment
As accompanying drawing 1, shown in 2, the utility model comprises the terraced frame bar 1 being symmetrical set, two ends are hinged at a plurality of steps 2 on terraced frame bar 1, be arranged on the plug 3 of terraced frame bar 1 one end and the insertion tube 4 that is arranged on terraced frame bar 1 other end, plug 3 on described terraced frame bar 1 is provided with plug tightening latch hole 31, insertion tube 4 on described terraced frame bar 1 is provided with insertion tube tightening latch hole 41, the interior tightening latch 5 that is plugged with respectively in described plug tightening latch hole 31 and insertion tube tightening latch hole 41, described step 2 is hinged with terraced frame bar 1 by the fixed axis 7 being set on otic placode 6, described tightening latch 5 two ends are provided with dismountable clamp nut 8.
The utility model in use, folding terraced frame bar 1 is opened, tightening latch 5 is inserted respectively in the plug tightening latch hole 31 and insertion tube tightening latch hole 41 on terraced frame bar 1, two tightening latches 5 and terraced frame bar 1 form firm framework, can not tilt, the step 2 being now hinged will be firm, as shown in Figure 4, when when construction single-unit the inadequate length of ladder time, two ladders can be continued, the plug of a ladder 3 is inserted in the insertion tube 4 of another ladder, now plug tightening latch hole 31 and the insertion tube tightening latch hole 41 of two ladders are overlapping, with tightening latch 5 cross-under, fix again, the cross section of plug 3 and insertion tube 4 is all rectangle, after pegging graft like this, terraced frame bar 1 is difficult for occurring the changing of the relative positions, can keep ladder more firm, the plug tightening latch hole 31 at ladder two ends now and insertion tube tightening latch hole 41 use tightening latches 5 are fixing, especially the clamp nut 8 on tightening latch 5 can allow ladder more firm, ladder will double like this, and convenient disassembly as shown in Figure 3, during transportation, is pulled down tightening latch 5, and the step 2 of hinge can be close by two of ladder terraced frame bars 1, reduces the volume of ladder, convenient carrying and transportation.
