Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details.
As shown in Figure 1, Figure 2 and Figure 3, the flat ladder of the insulation outlet with guardrail that this utility model provides, main including flat ladder
Body, two guardrails 20 and several support bars 30；Described flat ladder main body includes two side rods 11, some cross bars 12 and two peaces
Full rope 13；Described two side rods 11 are parallel to each other, and described cross bar 12 is fixed between two described side rods 11；Each described horizontal stroke
Bar 12 is all vertical with two described side rods 11；One end of each described safety rope 13 connects a described cross bar 12, the other end
It is provided with catching device 14；Two described guardrails 20 are connected with two described side rods 11 by described strut 30, fix two described limits
The surface of bar 11, parallel with two described side rods 11 respectively；Each described strut 30 and described side rod 11 and described guardrail
20 is all to be connected by roller 31.
Concrete, the two ends of each described strut 30 are equipped with roller 31；Described roller 31 is fixed on described in each
On strut 30；Each described roller 31 is provided with a groove 32；Each described guardrail 20 and each described side rod 11
On be provided with several fixing devices 40 in identical position；Each described fixing device 40 include two pieces of baffle plates 41, spring 42,
Bullet block 43 and bolt 44；The centre of each piece of described baffle plate 41 is provided with through hole, and described bullet block 43 is arranged on by described spring 42
