Specific embodiment
From the embodiment shown in Fig. 1-4, it includes the first limiting plate 1, the second limiting plate 2 and bearing pin 3；Described
The left part of one limiting plate 1 is provided with the first fixing hole 1-2, is provided with draw-in groove 1-1 in the middle part upper end of the first limiting plate 1；Described pin
Axle 3 is arranged on the right part of the first limiting plate 1；It is provided with the second fixing hole 2-3 in the right part of described second limiting plate 2, in institute
The left part stating the second limiting plate 2 is provided with the horizontal clamp 2-1 at a right angle with the second limiting plate 2；In described second limiting plate 2
Middle part is provided with bearing pin slotted eye 2-2；It is hinged that described second limiting plate 2 and the first limiting plate 1 pass through bearing pin 3.
Described bearing pin 3 adopts screw bearing pin.
This utility model safety interlocking stop passes through the first fixing hole 1-2 and the second fixing hole 2-3 installation respectively and is in
With (installing in ladder both sides) on two terraced side legs.
This utility model using method is as follows：Open household ladder, horizontal clamp 2-1 of the present utility model is pushed draw-in groove 1-
In 1, this utility model is made to be in spacing state (being in horizontality).Now, horizontal clamp 2-1 withstands draw-in groove 1-1, ladder
Cannot inwardly close, serve position-limiting action；If the two of ladder supporting legs are outwards skimmed, when bearing pin 3 moves to bearing pin slotted eye
To cannot move again during the left end of 2-2, equally serve position-limiting action.Ladder, using after finishing, only need to pull out the first limit
Position plate 1 and the second limiting plate 2, make horizontal clamp 2-1 abjection draw-in groove 1-1, and push up and can pack up ladder.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any modification, equivalent and improvement made within new spirit and principle etc., is all contained in protection of the present utility model
Within the scope of.
