Description
Technical field
The utility model is related to power maintenance tool technical field, especially a kind of Portable insulation ladder.
Background technology
In the prior art, in the inspection of power consumer Electro-metering device and daily operation power maintenance work, often
Ladder can be used.At present, it is general using bamboo ladder or folding ladder, because power supply station of basic unit carries out power utility check and line service
Mini-type mobile machinery shop is mostly used, and the terraced volume of bamboo is too big, it is not portable；And the folding ladder of in the market is mostly metal structure, nothing
Insulating properties.And the ladder that power department is used must have good insulating properties.Therefore, a kind of Portable insulation ladder is studied
Just seem more and more important.
The content of the invention
To overcome the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of Portable insulation ladder, with
The need for meeting the daily power utility check of electrical employee and maintenance work.
For achieving the above object, the utility model includes main terraced leg, support arm, foldable crosspiece, anti-skidding insulation sleeve；
The top of the main terraced leg is hinged with support arm, and bottom is cased with anti-skidding insulation sleeve, and the terraced body of the main terraced leg is provided with pin-and-hole one, can
Crosspiece is folded to be hinged with main terraced leg through pin-and-hole one.
The foldable crosspiece is separated in being, under be articulated and connected structure, the outer top of two ends pin-and-hole two of foldable crosspiece
Chamfering be can be achieved to be folded up, the arc-shaped of straight expansion downwards.
Extension spring is provided between the top of the main terraced leg and support arm；The top of main terraced leg, the bottom of support arm are with oblique
Face, opens support arm, and the angle between support arm and main terraced leg is 90 degree -140 degree.
The pin-and-hole one has 4-6 groups, and the spacing between its adjacent sets is 40-60cm.
The utility model is compared with prior art, safe and reliable with preferable insulating properties, foldable crosspiece design side
Portable belt, can meet the demand of the different occasions of electricity market.

Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, the utility model includes main terraced leg 1, support arm 2, foldable horizontal stroke
Shelves 3, anti-skidding insulation sleeve 4.The top of the main terraced leg 1 is hinged with support arm 2, is passed through between the top of main terraced leg 1 and support arm 2
Extension spring 6 is connected, and the top of main terraced leg 1, the bottom of support arm 2 carry inclined-plane, opens support arm 2, support arm 2 and main terraced leg 1 it
Between angle be 90 degree -140 degree；The bottom of main terraced leg 1 is cased with anti-skidding insulation sleeve 4；Pin is provided with the ladder of the main terraced leg 1
Hole 1, foldable crosspiece 3 is separated in being, under be articulated and connected structure, the outer top chamfering of two ends pin-and-hole 27 of foldable crosspiece 3
To can be achieved to be folded up, the arc-shaped of straight expansion downwards, foldable crosspiece 3 with pin through pin-and-hole 1, pin-and-hole 27 with it is main
Terraced leg 1 is hinged, and the pin-and-hole 1 has 4-6 groups, and the spacing between its adjacent sets is 40-60cm.
In use, insulating ladder is vertical, one end of anti-skidding insulation sleeve 4 is contacted with ground, it is ensured that insulating ladder insulate with the earth
And it is anti-skidding, two main terraced legs 1 are separated, the foldable stress of crosspiece 3, which is strutted downwards, stretches, the articulated structure of the foldable bottom of crosspiece 3
Crosspiece straight expansion downwards can be ensured；Open support arm 2 simultaneously, extension spring 6 cross the center of being hinged make support arm 2 and main terraced leg 1 by
Outwards, upward slightly larger than 90 degree angles of pulling force formation, extension spring 6 ensures that the top of main terraced leg 1 and support arm 2 are connected.Make
With finishing, during folding, ladder is inverted（Anti-skidding insulation sleeve 4 is in upper end）, after foldable crosspiece 3 is folded down, make two main ladders
Leg 1, which closes up, to be combined, and the outside upper circumference arcuation chamfering of two ends pin-and-hole 27 of foldable crosspiece 3 can ensure that two main terraced legs 1 close up
Closely, support arm 2 is moved back to downwards, extension spring 6 is reclaimed, support arm 2 is attached on main terraced leg 1 so that whole ladder structure is compact, side
Portable belt.
According to different needs, main terraced leg 1 can make two sections or three sections, and configure connecting rod, while being easy to carry, will
Two sections or the three main terraced legs 1 of section are connected by connecting rod, and height is used to increase ladder.
