Abstract
The utility model relates to an insulating ladder. A plastic insulation layer is arranged on the exterior of a metal ladder. The insulating ladder which is suitable for being used under various kinds of environment is safe even when electric equipment and power supply lines are arranged around. The utility model avoids the occurrence of electric shock accidents.
Description
The utility model relates to a kind of insulating ladder.
The ladder that uses in the prior art mostly is that aluminum alloy materials makes, there are consumer and supply line to be absolutely unsafe in use, so when implementing ascend operation, must pay close attention to protection against electric shock, but can not stop the generation of unsafe factor fully.
The purpose of this utility model provides a kind of insulating ladder safe in utilization.
The purpose of this utility model is achieved in that insulating ladder is that plastic insulating layer (2) is set outside wire ladder (1).
Compare with prior art, the utility model is owing to be covered with insulating layer at wire ladder, so it also is the very safe generation of having avoided electric shock accidents that consumer and supply line are arranged on every side, insulaion resistance through checking ladder is more than or equal to 10M Ω, and withstand voltage test does not have the puncture network through 2000V.1min, and proof voltage is less than 20,000 volts, load-bearing increases than aluminium alloys ladder, load-bearing 980N.2h skeleton not warpage does not rupture, and low temperature resistant-40 ℃, high temperature resistant 75-80 ℃.
Be described in detail technical solution of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the perspective view of insulating ladder.
Fig. 2 is the A-A sectional view along Fig. 1.
As Fig. 1,2, be outside equipped with plastic insulating layer at wire ladder 1, described ladder can be lift, two ladder (double ladder), single ladder or side-rolling ladder.
Claims (1)
1, a kind of insulating ladder is characterized in that being provided with plastic insulating layer (2) outside wire ladder (1).
