[0029] Figures 1 to 4 An embodiment of the ladder device of the present invention is shown. The ladder device of this embodiment includes a ladder body 1. Side support legs 2 and ground-inserting auxiliary support assemblies 3 are respectively provided on both sides of the bottom of the ladder body 1. The top ends of the side support legs 2 are hinged to the ladder body 1. The rotation axes of the side support legs 2 are perpendicular to the plane where the ladder body 1 is located. A support rod 4 is provided between the side support legs 2 and the ladder body 1. The ground-inserting auxiliary support assembly 3 includes a guide sleeve 31 and a ground-inserting rod 32. The guide sleeve 31 is provided on the ladder body 1, and the ground-inserting rod 32 is movably inserted into the guide sleeve 31.

[0030] Taking ground use as an example, when in use, the bottom of the ladder body 1 is placed on the ground, and the two side legs 2 are respectively extended to the sides of the ladder body 1, so that the bottom of the side legs 2 are supported on the ground. The support rod 4 is extended and supported between the side legs 2 and the ladder body 1, and the ground insertion rod 32 is inserted into the ground (of course, if on a hard surface, the ground insertion auxiliary support assembly 3 is not used). The top of the ladder body 1 is against the wall. Because the rotation axis of the side legs 2 is perpendicular to the plane of the ladder body 1, that is, the side legs 2 rotate on the plane of the ladder body 1, the two side legs 2 are extended to the sides of the ladder body 1 to form a support, preventing the ladder body 1 from tipping over and improving safety. In addition, the ground insertion rod 32 can be inserted into the ground to prevent the ladder body 1 from shaking, improving the stability of the operation.

[0031] Furthermore, in this embodiment, both ends of the support rod 4 are rotatably connected to the side support legs 2 and the ladder body 1, and the support rod 4 can be folded. Of course, in other embodiments, the support rod 4 and the side support legs 2 and the ladder body 1 can also be detachably connected.

[0032] Further, if Figures 2 to 4 As shown, in this embodiment, the support rod 4 includes a first rod segment 41, a second rod segment 42 and a hinge 43. One end of the first rod segment 41 is rotatably connected to the side support leg 2, and one end of the second rod segment 42 is rotatably connected to the ladder body 1. The other ends of the first rod segment 41 and the second rod segment 42 are hingedly connected by the hinge 43. The other ends of the first rod segment 41 and the second rod segment 42 are hingedly connected by the hinge 43, and can be rotated around the rotation axis of the hinge 43 to achieve folding, as shown in FIG. Figure 4 When the hinge 43 is folded, it drives the side legs 2 to rotate toward the ladder body 1, reducing the space occupied by the side legs 2 when they are unfolded, which is convenient for transportation.

[0033] Further, if Figure 3As shown, in this embodiment, the hinge 43 includes two leaves 431, which are respectively fixed to the end surfaces of the first and second rod segments 41, 42. The bottom edges of the two leaves 431 are pivotally connected. The pivotal connection of the bottom edges of the two leaves 431 allows the first and second rod segments 41, 42 to fold and collapse only by flipping upward. Conversely, the first and second rod segments 41, 42 can flip downward to unfold under the action of gravity. The two leaves 431 are tightly attached to each other to maintain the first and second rod segments 41, 42 in a supported state in a straight line. This structural design is ingenious and easy to operate. Furthermore, a collinear positioning assembly can be provided between the first and second rod segments 41, 42. When the first and second rod segments 41, 42 are collinear, the collinear positioning assembly is used to fix the first and second rod segments 41, 42. For example, the collinear positioning assembly includes a positioning rod, the ends of which are connected to the first and second rod segments 41, 42 by screws.

[0034] Furthermore, in this embodiment, a first connecting seat 5 is provided on the side support leg 2, a second connecting seat 6 is provided on the ladder body 1, the first rod segment 41 is rotatably connected to the first connecting seat 5, and the second rod segment 42 is rotatably connected to the second connecting seat 6.

[0035] Furthermore, in this embodiment, the second connecting base 6 is fixed to the ladder body 1 by bolts, and the first connecting base 5 is fixed to the side support leg 2 by bolts. The structure is simple and easy to assemble and disassemble.

[0036] Further, if Figure 2 and Figure 4 As shown, in this embodiment, the top end of the ground-inserting rod 32 is provided with a hammer handle 321 and the bottom end is provided with a cone tip 322. When inserting the ground, the hammer handle 321 is hammered to make the cone tip 322 penetrate the ground.

[0037] Furthermore, in this embodiment, an axial slot 311 and a circumferential slot 312 are provided on the side wall of the guide sleeve 31. The axial slot 311 is provided along the axial direction of the guide sleeve 31, while the circumferential slot 312 is provided along the circumference of the guide sleeve 31 and communicates with the top end of the axial slot 311. A limiting rod 323 is provided on the side wall of the ground insertion rod 32. The limiting rod 323 is movably inserted into the axial slot 311 or the circumferential slot 312. When not in use, the ground insertion rod 32 slides upward, causing the limiting rod 323 to move up along the axial slot 311 to the top end. The limiting rod 323 then rotates circumferentially relative to the guide sleeve 31, causing the limiting rod 323 to move to the circumferential slot 312. Under the limiting action of the circumferential slot 312, the ground insertion rod 32 is kept in a high position and does not extend below the ladder body 1. Preferably, one end of the circumferential sliding groove 312 away from the axial sliding groove 311 may be recessed or tilted downward, so as to achieve a better circumferential limiting effect on the limiting rod 323 .

[0038] Furthermore, in this embodiment, switchable magnetic bases 7 are provided on either side of the top of the ladder body 1. These bases allow the top of the ladder body 1 to rest against a wall, particularly an iron wall, where they can be magnetically attracted to the wall, further improving the stability of the ladder body 1. In this embodiment, the switchable magnetic bases 7 are conventional commercially available products, model number MAGTIGER.

[0039] Further, if Figure 1 As shown, in this embodiment, the switch-type magnetic base 7 is mounted on the ladder body 1 via a mounting base 8. The mounting base 8 is provided with a U-shaped groove. The magnetic body of the switch-type magnetic base 7 is disposed within the U-shaped groove and extends from the opening side of the U-shaped groove. The adjustment handle of the switch-type magnetic base 7 extends into the U-shaped groove. The mounting base 8 can be rotatably mounted on the ladder body 1 or fixed to the ladder body 1 with the opening of the U-shaped groove facing the wall.
