further comprising a reinforcement pin 7;

if the second ladder body 3 is 180 degrees from the first ladder body 2, the reinforcing pin 7 penetrates through the first through hole 27 and the second through hole 35.

Specifically, in order to ensure the strength of the on-vehicle folding ladder 1 and prevent the joint of the first ladder body 2 and the second ladder body 3 from being broken, in this embodiment, the protruding portion 26 is arranged on the first end surface 24, the protruding portion 26 is of a flat structure and has any shape, the second end surface 31 is provided with an accommodating groove 34 adapted to the protruding portion 26, and when the second ladder body 3 and the first ladder body 2 are in an angle of 180 degrees, the protruding portion 26 is accommodated in the accommodating groove 34 to increase the connection between the first ladder body 2 and the second ladder body 3 and enhance the connection strength; the protruding portion 26 is provided with a first through hole 27 penetrating through the protruding portion 26, a groove wall of the receiving groove 34 is provided with a second through hole 35, that is, the side sill 22 is divided into two parts by the receiving groove 34, the two parts are provided with the second through holes, and the second through hole 35 is communicated with the outside, that is, the second through hole 35 penetrates through the side sill 22 of the second ladder body 3; after the protruding portion 26 enters, the first through hole 27 corresponds to and is communicated with the two second through holes 35, and further when the second ladder body 3 and the first ladder body 2 are in an angle of 180 degrees, the reinforcing pin 7 penetrates through the second through hole 35 on one side of the side beam 22 and sequentially penetrates through the first through hole 27 and the second through hole 35 on the other side of the side beam 22, so that the connection strength is enhanced, and the second ladder body 3 and the first ladder body 2 are prevented from being in a 180-degree collision with the ground for supporting and climbing, and treading breakage is avoided; wherein, it can be understood that the reinforcing pin 7 can be in the form of a nut, and the nut can be arranged at the other end after penetrating through the side beam 22 to ensure the connection stability; moreover, the reinforcing pins 7 may be respectively provided in 2 corresponding to the two side beams 22, or may be provided in one to continuously penetrate, and the arrangement can be easily understood and implemented by those skilled in the art, and will not be described in detail herein.

Example 2

Referring to fig. 3, the present embodiment provides a vehicle 4, which includes a cabin 42 and at least one on-board folding ladder 1;

the carriage 42 comprises at least one reversible carriage plate 41, and the first ladder body 2 of at least one on-board folding ladder 1 is connected to the at least one carriage plate 41 through a rotary connecting part 21.

Specifically, in this embodiment, the vehicle-mounted folding ladder 1 is the vehicle-mounted folding ladder 1 according to the embodiment, and the detailed description of the specific structure and the working principle of the vehicle-mounted folding ladder 1 is referred to in the embodiment 1, which is not repeated herein; of course, it is to be understood that: at least one vehicle-mounted folding ladder 1 can be arranged on the first carriage plate 41; at least one vehicle-mounted folding ladder 1 can be arranged on each of the carriage plates 41.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
