The wheels 110 are used to realize the movement of the chassis 100, so that the chassis 100 has a shipping function. The height limiting base 120 is used to limit the angle of the supporting frame 200 in a state of realizing the function of the platform ladder, thereby limiting the height of the stepping frame 300.

The bottom chassis 100 may be formed in a flat plate shape or may be designed to have a hollow-out shape. In this embodiment, the bottom frame 100 includes two long rods 101 arranged in parallel. The two long rods 101 are arranged in parallel. A plurality of cross beams 102 can be arranged between the two long rods 101, and the cross beams 102 are arranged in parallel and are perpendicular to the long rods 101. At this time, the beam 102 may carry an article. Or a bottom plate 103 is provided between the two long bars 101 for holding the articles.

The load-bearing part of the beam 102 or the base plate 103 is smaller than the length of the two long rods 101. This design facilitates the rotation of the support stand 200 and at the same time, the thickness of the bottom plate 103 or the cross beam 102 is smaller than that of the long rod 101 for the convenience of carrying. One side of the bottom frame 100 is provided with a connecting shaft 104 for realizing a hinged connection with the supporting frame 200.

The support frame 200 has two functions, namely, a handle or a push rod for realizing the consignment function, and a support function for the trampling frame 300 in the function of the platform ladder. The supporting stand 200 includes a supporting bar 201 and a hand-held bar 202. In the folded state, the supporting bracket 200 is parallel to the base frame and is located at the upper portion of the base frame 100.

The number of the support rods 201 is two, and the two support rods 201 are arranged in parallel. The distance between the two support rods 201 is smaller than the width of the base frame 100. The handheld rod 202 is fixedly connected with the ends of the two support rods 201. The hand-held rod 202 is also perpendicular to the long rod 101, thereby facilitating hand-holding. The free end of the supporting rod 201 is provided with a through hole or a ring 203, and the through hole or the ring 203 is sleeved on the connecting shaft 104 to realize the hinging of the supporting frame 200 and the underframe 100.

The height-limiting seats 120 are provided in two numbers, and the two height-limiting seats 120 are respectively overlapped with the two support rods 201 in the vertical direction. Or one height limiting seat 120 is arranged, the height limiting seat 120 is in a strip shape, two ends of the height limiting seat 120 are fixedly connected with the long rod 101, and the height limiting seat 120 and the wheels 110 are positioned on the same bottom surface. The height-defining seat 120 is located between the connecting shaft 104 and the wheel 110, and the height of the height-defining seat 120 is less than the height of the wheel 110. Therefore, the height-defining seat 120 may be located as close as possible to the connecting shaft 104.

In the folded state, the stepping frame 300 is located between the base frame 100 and the supporting frame to facilitate folding and carrying. The stepping frame 300 comprises a rotating ring 301 and a pedal 302, wherein the rotating ring 301 is provided with a horizontal limiting seat 310. The number of the rotating rings 301 is two, the rotating rings 301 are sleeved on the handheld rod 202, and the pedal 302 is fixedly connected with the two rotating rings 301 through a connecting piece. The distance between the two rotating rings 301 is larger than the distance between the two supporting rods 201.

The horizontal limiting seat 310 is a cross bar, and the horizontal limiting seat 310 is parallel to the handheld rod 202 and is fixedly connected with the two rotating rings through a connecting piece.

As shown in fig. 2, the state is a shipping state in which the wheels 110 contact the ground. The supporting frame 200 is opened at a certain angle to realize dragging.

As shown in fig. 3, the state is a ladder state in which the wheels 110 are directed upward, and the side of the base frame 100 that is turned upside down without wheels contacts the ground, thereby ensuring the stability of the base frame 100. At this time, the turning angle of the supporting frame 200 is larger than 180 degrees. Then, the stepping frame 300 is continuously turned over to make the stepping frame 300 in a horizontal state. So that the person steps on.

Preferably, the length of the bottom frame 100 is the same as that of the supporting frame 200, and the length of the stepping frame 300 is half of that of the bottom frame 100. The length direction of the height limiting base 120 is vertical and perpendicular to the bottom frame. When the supporting frame 200 contacts the height-limiting seat 120, the height-limiting seat 120 forms an included angle of 60 degrees with the supporting frame 200. The horizontal limiting seat 310 forms an angle of 120 degrees with the treading frame 300. At this time, in the step state, the free end of the base frame 100 and the free end of the stepping frame 300 are flush in the vertical direction. Therefore, the high-voltage cabinet can be kept flush with the side face of the vertical high-voltage cabinet body, and the state of the platform ladder is more stable.

Further, in order to realize the stability of the platform ladder state, the free end of the treading frame 300 is provided with a magnet so as to adsorb the cabinet body of the high-voltage cabinet. Or, the free end of the stepping frame 300 is provided with a rubber sheet to increase the friction between the free end of the stepping frame 300 and the high-voltage cabinet body, thereby increasing the stability. Or, a magnet wrapped by rubber is arranged at the free end of the treading frame 300. When the stepping frame 300 is a flat plate, the free end is flat so as to be convenient. When the treading frame 300 is composed of parallel cross bars, the cross bar at the outermost side is a free end.

Preferably, in order to increase the stability in the folded state, the opening and closing ends of the bottom chassis 100 and the supporting frame 200 are respectively provided with a locking block made of a magnetic material and an adsorption block made of a magnetic material. At this time, the base frame 100 and the supporting frame 200 are attracted to each other, and the treading frame 300 is located between the two, so that the whole body can be more stable.
