The staff can easily reach the high shelves by stepping on the ladder without the need to climb with the help of other tools, thereby improving work efficiency and reducing safety risks. After replenishment is completed, the footrest 6 can be rotated to be retracted between the pair of uprights 3 without affecting the movement and storage of the trolley, saving space.

[0034] like Figure 1 and Figure 2 As shown, cross bars 5 are horizontally arranged in the bottom frame 1 and the top frame 2, and multiple cross bars 5 are arranged side by side, which is conducive to the storage and placement of smaller goods. The stepping frame 6 is set to a U-shaped structure, and the open end of the stepping frame 6 is rotatably assembled and connected to the column 3. Multiple arms 13 are horizontally arranged in the stepping frame 6, which is convenient for staff to step on their feet.

[0035] like Figures 1 to 4 As shown, a convex shaft 11 is provided on the outer side wall of the open end of the footrest 6, and a slide groove 9 for the convex shaft 11 to slide is vertically opened on the column 3. A first positioning pin 12 is passed through the open end of the footrest 6, and the first positioning pin 12 passes through the convex shaft 11 and extends into the slide groove 9. A first positioning hole 10 that is plugged into and cooperates with the first positioning pin 12 is opened on the column 3. A plurality of first positioning holes 10 are opened at equal intervals. The convex shaft 11 is slid along the slide groove 9 to make the footrest 6 rise and fall. The first positioning pin 12 is plugged into the first positioning hole 10 at the corresponding position to position the height of the footrest 6, thereby realizing the height adjustment of the footrest 6. The support arm 7 includes a fixed sleeve arm 14 vertically fixed to the bottom of the end of the stepping frame 6 away from the column 3 and a movable arm 15 movably inserted into the bottom end of the fixed sleeve arm 14. A second positioning pin 17 is movably inserted into the bottom end of the fixed sleeve arm 14.

After releasing the paddle 23, the elastic force of the spring 22 pushes the pair of sliders 20 away from each other, thereby pushing the pair of first positioning pins 12 or the pair of second positioning pins 17 away from each other, so that the first positioning pin 12 is plugged into the first positioning hole 10 or the second positioning pin 17 is plugged into the second positioning hole 16, thereby achieving height adjustment.

[0037] The working principle of the technical solution provided by the utility model is as follows:

[0038] When in use, the bottom frame 1 and the top frame 2 have a layered structural design, which can store replenishment boxes and empty boxes respectively, which is convenient for sorting and classification, and reduces the time of picking up goods back and forth. A handle 4 is installed at one end of the top frame 2 to facilitate the staff to pull the trolley to move. Through the arrangement of the footrest 6 and the support arm 7, when replenishment is needed at a high place, the footrest 6 is rotated away from the column 3, and the support arm 7 horizontally supports the footrest 6 to form a ladder structure. The staff can easily reach the high shelves by stepping on the ladder without the need to climb with the help of other tools, which improves work efficiency and reduces safety risks. After replenishment is completed, the footrest 6 can be rotated to between a pair of columns 3 and retracted, which does not affect the movement and storage of the trolley and saves space.

[0039] Furthermore, the pair of paddles 23 on the auxiliary arm 18 corresponding to the stepping frame 6 are pushed closer to each other, and the slider 20 and the push rod 21 drive the pair of first positioning pins 12 to move closer to each other. The first positioning pins 12 are separated from the first positioning holes 10 on the column 3. At this time, the stepping frame 6 can be pushed to make the convex shaft 11 slide up and down along the slide groove 9. After releasing the pair of paddles 23, the spring 22 pushes the pair of sliders 20 away from each other. At this time, the push rod 21 pushes the pair of first positioning pins 12 to insert into the first positioning holes 10 at the corresponding positions on the column 3, so that the height of the stepping frame 6 can be adjusted. According to the above structure, The paddle 23 on the auxiliary arm 18 between the pair of fixed sleeve arms 14 disengages the second positioning pin 17 from the second positioning hole 16 on the movable arm 15, and the movable arm 15 at the bottom end of the fixed sleeve arm 14 can be pulled and pulled, and after the paddle 23 is released, the second positioning pin 17 is pushed to engage with the second positioning hole 16 at the corresponding position on the movable arm 15, and the overall length of the support arm 7 can be adjusted to adapt to the height of the footrest 6. In this way, the height of the ladder structure composed of the footrest 6 and the support arm 7 can be adjusted to meet the height requirements of replenishment, with high flexibility, providing convenience for the staff's replenishment operation.

[0040] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
