When the second ladder body 200 is folded to the front side of the first ladder body 100, that is, when the folding ladder is in a folded state, the connecting hooks 212 can be clamped with the connecting rings 113, and then the movable block 114 rotates around the first fixed block 111 to a position where the rotating rod 112 is far away from the connecting hooks 212, so that the connecting hooks 212 and the connecting rings 113 can be in a locking position, thereby realizing the locking of the first ladder body 100 and the second ladder body 200, and the folding ladder is kept in the folded state without influencing the normal running of the vehicle.

When it is desired to climb to the roof using the folding ladder, the movable block 114 is pulled open so that the rotation rod 112 is positioned close to the connection hook 212, and the connection ring 113 can be separated from the connection hook 212, thereby allowing the second ladder body 200 to rotate to the unfolded state about the rotation shaft.

In other embodiments, the first locking member 110 and the second locking member 210 are removably coupled by magnetic attraction, bolting, or the like.

In the present embodiment, the first locking member 110 and the second locking member 210 are provided with two, respectively. The two first locking parts 110 are respectively provided at the left and right sidewall surfaces of the first ladder body 100, i.e., the two first locking parts 110 are respectively connected with the two first columns 150. Two second locking parts 210 are respectively provided at left and right sidewall surfaces of the second ladder body 200, that is, the two second locking parts 210 are respectively connected with two second columns 230.

It will be appreciated that since the extension ladder 300 is fixedly coupled to the first ladder 100, the first locking member 110 may also be mounted on the two inclined posts 320 of the extension ladder 300.

It can be appreciated that the first locking parts 110 and the second locking parts 210 are connected in one-to-one correspondence and detachably, when the first locking part 110 located at the left side of the first ladder body 100 is connected with the second locking part 210 located at the left side of the second ladder body 200, the first locking part 110 located at the right side of the first ladder body 100 is connected with the second locking part 210 located at the right side of the second ladder body 200, the upper end of the first ladder body 100 is locked with the lower end of the second ladder body 200, and deformation caused by uneven left and right stress of the first ladder body 100 and the second ladder body 200 can be avoided, thereby improving the service life of the folding ladder.

In addition, the embodiment of the utility model also provides a motor home, which comprises a car body and the folding ladder provided in any embodiment, wherein the first ladder body 100 of the folding ladder is connected with the side wall surface of the car body, and the upper end of the extension ladder body 300 extends to the upper surface of the car body and is connected with the upper end of the car body.

It can be understood that because the folding ladder is arranged on the caravan, a user can conveniently and safely climb to the upper surface of the car body, the space at the top of the caravan is better utilized, and moreover, the folding ladder can not influence the normal running of the caravan.

While the preferred embodiment of the present utility model has been described in detail, the utility model is not limited to the embodiments, and various equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the utility model, and these modifications and substitutions are intended to be included in the scope of the present utility model as defined in the appended claims.
