Detailed description of the invention
Below in conjunction with some specific embodiments, this utility model is further illustrated.
Embodiment 1
Seeing Fig. 1-3, a kind of single pole hanging ladder, including ladder bars 1, described ladder bars 1 cross section is square, and described ladder bars 1 is pushed up
End arranges hook 2, and described ladder bars 1 is provided with the pedal 3 that the first from left dextrad side is stretched out, and described pedal 3 edge arranges arc hands
Handle 4, described curved handle 4 other end connect ladder bars 1, described ladder bars 1 lower end welding a piece expansion link 5, described expansion link 5 another
End one arc backup plate 6 of welding, described arc backup plate 6 two ends respectively arrange an elastic threads 7, in described hook 2 and arc backup plate 6
Side arranges anti-skidding projection, fixing more firm.
During the use of this utility model single pole hanging ladder, first adjustable telescopic rod 5 to appropriate length, then by single pole hanging ladder top
What end hook 1 hung over winding staircase bottom on electric pole stares on bar, and the arc backup plate 6 being connected with expansion link 5 presses close to the lower end of electric pole, and
Arc backup plate 6 and electric pole being fixed by elastic threads 7, now, single pole hanging ladder and electric pole fixation, single pole hanging ladder is not easy arbitrarily
Rocking, during climbing, two hand steered tight bowhandles 4, foot steps on pedal, the most upwards climbs.
Embodiment 2
Seeing Fig. 4, a kind of single pole hanging ladder, including ladder bars 1, described ladder bars 1 cross section is rectangle, described ladder bars 1 top
