[0045] In addition, the first leg 10 can also be hinged to the platform portion 20. This connection form can realize the relative rotation of the first leg 10 and the platform portion 20, thereby reducing the space occupied when stored. It should be noted that in this connection state, a corresponding fixing structure needs to be added to ensure the fixed connection between the first leg 10 and the platform portion 20 in the working state.

[0046] The platform portion 20 includes a first load-bearing beam 22, a second load-bearing beam 27, a load-bearing plate 21 and a limit beam 26. The load-bearing plate 21 is fixedly arranged between the first load-bearing beam 22 and the second load-bearing beam 27 to provide a larger working platform for the operator. When the operator is working, he can stand or sit on it to avoid fatigue caused by standing on the footrest for a long time.

[0047] Preferably, the bearing plate 21 is welded and fixed to the first bearing beam 22 and the second bearing beam 27 .

[0048] Furthermore, the first leg body 11 is fixedly welded to the second bearing beam 27 , and the second leg body 13 is fixedly welded to the first bearing beam 22 .

[0049] One end of the bearing plate 21 is fixedly connected to the first bearing beam 22, and the other end of the bearing plate 21 is fixedly connected to the second bearing beam 27. The limiting beam 26 includes a first limiting surface 25; the limiting beam 26 is arranged at one end where the second leg 30 is connected to the platform portion 20, and there is no other blocking structure from the first limiting surface 25 to the edge of the platform portion 20.

[0050] In addition, the first load beam 22 and the second load beam 27 are both provided with a first mounting hole 24 for connecting the second leg 30 .

[0051] The second leg 30 includes a connecting beam 31, a mounting beam 35 and a supporting beam 34; the connecting beam 31 is provided with a second limiting surface 33 that can cooperate with the first limiting surface 25 to achieve a limiting function; the connecting beam 31 and the mounting beam 35 are arranged in parallel; the supporting beam 34 is arranged between the connecting beam 31 and the mounting beam 35; one end of the supporting beam 34 is fixedly connected to the connecting beam 31, and the other end of the supporting beam 34 is fixedly connected to the mounting beam 35.

[0052] Preferably, the length of the connecting beam 31 is greater than the length of the mounting beam 35 .

[0053] Preferably, the support beam 34 has three pieces, and the outer surfaces are coplanar, so that the second leg 30 can rely on the support beam 34 as a platform for standing or sitting when in the second working state. At the same time, there is a gap between adjacent support beams 34, so that the weight of the multifunctional ladder can be effectively reduced.

[0054] In addition, the multifunctional ladder further comprises a latch shaft for connecting the second leg 30 with the platform portion 20. The connecting beam 31 has a connecting pin hole 32 passing through it; the latch shaft can be inserted into the first mounting hole 24 and the connecting pin hole 32 at the same time to realize the hinge connection between the second leg 30 and the platform portion 20.

[0055] The mounting component 40 includes a connecting portion 41 and a hook 43; the connecting portion 41 is provided with a mounting groove 45 for matching with the mounting beam 35; the hook 43 is fixedly connected to the connecting portion 41; the opening surface of the hook 43 faces the first leg 10. The connecting portion 41 is provided with mounting member connecting holes 42 passing through it, and the positions of the mounting member connecting holes 42 are the same in number and corresponding to the mounting fixing holes 36. The arrangement of the mounting member connecting holes 42 and the mounting fixing holes 36 enables the bolts to pass through both the connecting portion 41 and the mounting beam 35, thereby realizing a detachable fixed connection between the mounting component 40 and the second leg 30.

[0056] At the same time, when the mounting component 40 and the second leg 30 are made of different materials, for example, the second leg 30 is made of aluminum alloy material and the mounting component 40 is made of iron material, the setting of the mounting component connecting hole 42 and the installation fixing hole 36 can avoid the problem of difficulty in welding and poor welding quality during welding of the two.

[0059] like Figure 5As shown, a multifunctional ladder is in a second working state, the first leg 10 stands on the ground, the mounting component 40 is mounted on a tree branch or other fixed object, the second limiting surface 33 in the second leg 30 and the first limiting surface 25 in the platform part 20 form a limiting structure, so that the multifunctional ladder is in a stable state. At the same time, the second leg 30 can be used as a platform for standing or sitting.

[0060] As another embodiment of the present invention, Figure 6 As shown, the platform portion 20 also includes a leg mounting groove 28 arranged between the bearing plate 21 and the limiting beam 26; the second leg 30 can be installed in the leg mounting groove 28; when the second leg 30 can be installed in the leg mounting groove 28, the multifunctional ladder can be in the third working state.

[0061] The platform portion 20 further includes a second mounting hole 23 for mounting the second leg 30; the second mounting hole 23 is disposed on the first load beam 22 and the second load beam 27 at positions corresponding to the leg mounting slots 28. The second leg 30 is hinged to the platform portion 20 through the plug-in action of the latch shaft.

[0062] In the third working state, the first leg 10 is arranged at an acute angle with the second leg 30. At the same time, the limiting beam 26 can limit the second leg 30, thereby ensuring that the multifunctional ladder is in a stable state.

[0063] As another embodiment of the present invention, Figure 7 As shown, a multifunctional ladder further includes a support leg 50; the support leg 50 has the same basic structure as the mounting component 40, except that the support leg 50 has a plurality of support legs, which are used to replace the hook 43 in the mounting component 40. In the third working state, the support leg 50 can replace the mounting component 40 and be detachably mounted on the bottom of the second leg 30, so that the multifunctional ladder is suitable for indoor hard ground environments, improves the stability of the multifunctional ladder, and prevents it from tipping over.
