[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0024] The reference numerals in the drawings of the specification include: support frame 1, wheel 2, first adjustment frame 3, second adjustment frame 4, pedal 5, baffle 6, support leg 7, ladder step 8, shaving support 9, clamping column 10, and clamping slot 11.

[0025] A multifunctional transport vehicle, for example Figure 1 As shown, it includes a support frame 1, a first adjustment frame 3, a second adjustment frame 4 and a pedal 5, and the specific structure is as follows:

[0026] The support frame 1 adopts an integrally welded channel steel structure. The left end of the support frame 1 is symmetrically provided with support legs, and the right end of the support frame 1 is symmetrically provided with moving wheels.

[0027] The first adjustment frame 3 and the second adjustment frame 4 are hinged to the left and right sides of the support frame 1 respectively. Three groups of baffles 6 for accommodating the first adjustment frame 3 are symmetrically provided on the inner side of the support frame 1 .

[0028] The right end of the pedal 5 is hinged to the left end of the second adjustment frame 4, and the left end of the pedal 5 is plugged into the right end of the first adjustment frame 3. The first adjustment frame 3 is provided with multiple steps 8, and the top step 8 is symmetrically provided with at least two clamping posts 10. The pedal 5 is provided with multiple slots 11 that respectively adapt to the clamping posts 10. The clamping posts 10 are arranged obliquely along the first adjustment frame 3. When the pedal 5 is engaged with the first adjustment frame 3, the clamping posts 10 are perpendicular to the surface of the support frame 1. The surface of the clamping posts 10 is provided with elastic protective pads, so that a compressible gap exists between the clamping posts 10 and the clamping slots 11, preventing the clamping posts 10 and the clamping slots 11 from becoming stuck and preventing the pedal 5 from being removed. The second adjustment frame 4 is evenly provided with multiple shaving stays 9, and the spacing between the shaving stays 9 near the pedal 5 and the pedal 5 is greater than the length of the pedal 5. The steps 8 and the shaving stays 9 are both made of stainless steel and welded to the first and second adjustment frames 3 and 4, respectively.

[0029] like Figure 1As shown, the support frame 1 is parallel to the ground, and the legs 7 are in contact with the ground, which supports and fixes the entire structure. Of course, the mobile wheels in this embodiment can be wheels 2 with brake pads to further improve the stability of the entire structure. The clamping column 10 is inserted into the clamping groove 11 of the pedal 5, so that the first adjustment frame 3 and the second adjustment frame 4 can jointly support the pedal 5 to form a rectangular ladder structure. At this time, the entire structure is used as a ladder; when the entire structure needs to be used as a cart, it only needs to be adjusted through the following steps, as follows:

[0030] The first step, such as Figure 2 As shown, one end of the pedal 5 is disassembled so that the clamping column 10 and the clamping slot 11 are separated from each other;

[0031] The second step is Figure 3 As shown, the pedal 5 is rotated so that the pedal 5 is embedded in the second adjustment frame 4;

[0032] The third step, such as Figure 4 As shown, the first adjustment frame 3 is rotated so that the first adjustment frame 3 is placed on the baffle 6 of the support frame 1;

[0033] The fourth step is as follows Figure 5 As shown, the second adjustment frame 4 is rotated so that the second adjustment frame 4 is overlapped with the surface of the first adjustment frame 3;

[0034] Step 5: Figure 6 As shown, the pedal 5 is rotated so that the top surface of the right end of the pedal 5 abuts against the ground of the ladder step 8, thereby forming a space for placing items. In this state, the entire structure forms a lever, wherein the fulcrum of the lever is the center of the hinge between the pedal 5 and the second adjustment frame 4, one end of the lever is the contact point between the pedal 5 and the ladder step 8, and the ladder step 8 limits the rotation of the pedal 5, and the other end of the lever allows items to be placed, and at this time the support leg 7 can be used as a handle, so that the entire structure can be used as a cart.

[0035] The utility model has a simple structure and is easy to store and can be used as both a ladder and a cart. It has high efficiency and a wide range of applications. It has high practical value while taking into account safety and dual uses.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
