Examples

The utility model provides a cat ladder for vertical-climbing foldable emergency ladder, be located emergency ladder fixed frame one side, the major structure is aluminum alloy material, including cat ladder body 6, the upper and lower both ends of cat ladder body 6 all articulate there is parallel connecting rod 3, parallel connecting rod 3's the other end articulates with emergency ladder fixed frame in order to form parallel four-bar linkage, make cat ladder body 6 can be for emergency ladder fixed frame translation, parallel connecting rod 3's below is equipped with limiting structure 2 of its rotational position of restriction, cat ladder body 6 is close to emergency ladder's footboard center when parallel connecting rod 3 contacts with limiting structure 2.

The cat ladder body 6 includes relative cat ladder stand 5 that sets up and a plurality of cat ladder horizontal poles 4 that are located between two cat ladder stands 5 and are connected with it, 4 perpendicular to cat ladder stands 5 of cat ladder horizontal pole. A middle upright post is arranged between the two ladder stand columns 5 so as to divide the ladder stand body 6 into two parts which are arranged left and right. The ladder stand column 5, the parallel connecting rods 3 and the limiting structures 2 are all square tube sectional material structures made of aluminum alloy materials.

The assembly method of this embodiment is as follows: firstly, weld into a whole with cat ladder horizontal pole 4 and cat ladder stand 5, secondly with limit structure 2 and emergency ladder fixed frame stand 1 fixed connection, then adopt the pivot to articulate parallel link 3 and emergency ladder fixed frame stand 1. When the escape ladder is unfolded, the movable frame of the escape ladder pops outwards, and the ladder stand rotates to the limiting structure 2 by means of gravity by taking the rotating shaft as the center, so that a downward climbing channel is formed. When the escape ladder is folded, the ladder stand is lifted upwards to fix the movable frame, so that the movable frame forms the limit of the ladder stand.
