Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model mainly comprises the first elevating mechanism 1, second upgrading mechanism 2, connection bracket 3, first insulation barrier 4 and the second insulation barrier 5, the first insulation barrier 4 is fixed in first elevating mechanism 1 upper end, second upgrading mechanism 2 upper end is fixed between the second insulation barrier 5, first elevating mechanism 1 and the second upgrading mechanism 2 and is linked into an integrated entity by connection bracket 3.
Described first elevating mechanism 1 comprises insulation elevator 6 and insulation fixed ladder 7, and connect the insulation elevator 6 that can slide up and down inside insulation fixed ladder 7 inside insulation fixed ladder 7, insulation fixed ladder 7 top fixed block seat 9, pulley base 9 is provided with pulley 10.Insulating cord 11 one end is fixed on insulation elevator 6 lower end, after the other end walks around pulley 10 from top to bottom, drawdown is to insulation fixed ladder 7 bottom, operating personnel hold insulating cord 11 drawdown end and pull at down, insulation elevator 6 just can rise along insulation fixed ladder 7, drives the insulation barrier of insulation elevator 6 upper end.
As shown in Figure 3, insulation elevator 6 top is for connecting insulation barrier, both sides, bottom are provided with ratchet holding tank 15, a ratchet 16 be fixed on pawl axis 13 is respectively equipped with in two ratchet holding tanks 15, pawl axis 13 is provided with torsion spring 14, torsion spring 14 end thereof contacts ratchet holding tank 15 inwall, other end contact ratchet 16, torsion spring 14 makes ratchet 16 extend in outside ratchet holding tank 15 in without external force situation.
As shown in Figure 4, ratchet 16 is provided with the first sour jujube tongue 17 and is provided with ratchet bayonet socket 18 first sour jujube tongue 17 between the second sour jujube tongue 19, first sour jujube tongue 17 and the second sour jujube tongue 19.
Insulation fixed ladder 7 is provided with multiple insulating ladder shelves 12, and multiple insulating ladder shelves 12 are uniformly distributed along insulation fixed ladder 7 short transverse.Insulation fixed ladder 7 two bottom sides is provided with insulating carriage 8, by the support strength of insulating carriage 8 reinforced insulation fixed ladder 7.
