Abstract
The utility model discloses a novel basic station cat ladder of preventing falling, the left montant of this cat ladder is a U -shaped card slot, and evenly distributed has the steel tooth in the draw -in groove, and right montant and horizontal pole are the normal pole of aluminium alloy material. A left side contains in the montant and prevents weighing down the subassembly, and this subassembly adopts wheel -type structure, and the bottom plate be the magnetic steel, and the size of the frictional force that its magnetic force produced is prevented the weight and is organized the gravity that the subassembly receives under just offsetting the vertical circumstances, makes it can not fall. Climbing person will detain safely to go into to prevent weighing down in the steel ring of subassembly lower extreme when this cat ladder of climbing. Prevent weighing down the subassembly under magnetic bottom board's effect, the frictional force of its production makes wholely prevents weighing down the subassembly and can not slide at will. In the time of about climbing person is normal, safe detain driving prevent weighing down the subassembly and reciprocate, if it falls suddenly, the steel ring downstream, latch in the trigger mechanism, the card is that personnel are in the whereabouts on the steel tooth. Play safety, firm effect prevents to fall.
