Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, protective device, including carriage are prevented in the household ladder multipurpose of the present embodiment
The top of upper beam 7, carriage upper beam 7 is fitted with car top protection fence components 3 by hinge 8, and car top protection fence components 3 turn over downwards
It is vertical with the top surface of carriage upper beam 7 when car top protection fence components 3 flip up with 7 either flush of carriage upper beam when folding；Car top
The bottom inside of protection fence components 3 is welded with channel steel 4, and the middle part of channel steel 4 is equipped with microswitch 5, and the both ends of channel steel 4 are pacified respectively
Equipped with pin shaft 6；The inside top position of car top protection fence components 3 is welded with bracket 1, and one end top surface of bracket 1 is cushion
101, limit switches 2 are installed in the other end top surface of bracket 1, and the top of limit switch 2 is higher than the top side location of cushion 101.
