[0032] like Figure 1 As shown, the utility model discloses a combined adjustable trolley, including a movable frame 100. The specific structure of the frame 100 can be referred to the existing patent CN221251358U, "A sulfuric acid transportation device", which will not be described here. A first support frame 31 and a second support frame 32 are provided on the frame 100; and a height difference is formed between the first support frame 31 and the second support frame 32. Support frames of different heights are used to carry products of different specifications, and for the sake of convenience of loading and unloading, it is preferred to place large-sized products on the second support frame 32 with a lower height; and small-sized products are placed on the first support frame 31 with a higher height.

[0033] like Figures 1 to 4 As shown, a first storage unit 1 is provided on the vehicle frame 1, and further, the first storage unit 1 is provided on the first support frame 31 of the vehicle frame 100. The first storage unit 1 is provided on the vehicle frame 100 through the base plate 10, and includes a supporting plate 102 parallel to the upper surface of the base plate 10, a group of positioning rods 11 and adjusting rods 12 passing through the supporting plate 102. The supporting plate 102 is formed with a through hole for facilitating the penetration of the positioning rod 11, and a waist-shaped hole for facilitating the penetration of the adjusting rod 12. The positioning rod 11 is distributed in an L-shape or a U-shape on the base plate 10 and the supporting plate 102; and the positioning rod 11 and the adjusting rod 12 form a first storage area 101 on the supporting plate 102. The adjusting rod 12 moves along the X-axis and / or Y-axis relative to the positioning rod 11 and the supporting plate 102 in the waist-shaped hole on the supporting plate 102, and cooperates with the positioning rod 11 to adjust the area of the storage area enclosed by the adjusting rod 12 and the positioning rod 11 according to the product size; that is, the area of the first storage area 101 can be adjusted by the distance between the adjusting rod 12 and the positioning rod 11 to adapt to products of different specifications and improve adaptation flexibility.

[0034] Specifically, such as Figure 2、 Figure 5 and Figure 6 As shown, the adjusting rod 12 includes an X-axis adjusting rod 121, and the X-axis adjusting rod 121 is driven by an X-axis transfer assembly 13 provided on the base plate 10. Figure 7 As shown, the X-axis transfer assembly 13 includes an X-axis power source 131, X-axis guide rods 132, and an X-axis movable plate 133 for mounting the adjustment rod 121. At least one X-axis guide rod 132 is arranged along the width of the base plate 10 and moves synchronously. The X-axis movable plate 133 is arranged in the same direction as the X-axis guide rod 132. The X-axis movable plate 133 is slidably connected to the X-axis guide rod 132 and is driven by the X-axis power source 131 to move along the length of the carrier plate 102.

[0035] like Figure 2 、 Figure 5 and Figure 6 As shown, the adjustment rod 12 further includes a Y-axis adjustment rod 122, and the Y-axis adjustment rod 122 is driven by the Y-axis transfer assembly 14 provided on the base plate 10, and the X-axis transfer assembly 13 and the Y-axis transfer assembly 14 do not interfere with each other. Figure 8 As shown, the Y-axis transfer assembly 14 includes a Y-axis power source 141, Y-axis guide rods 142, and a Y-axis movable plate 143 for mounting the Y-axis adjustment rod 122. A set of Y-axis guide rods 142 are arranged along the length of the base plate 10. The Y-axis movable plate 143 spans the set of Y-axis guide rods 142 and is parallel to the X-axis movable plate 133. The Y-axis movable plate 143 is slidably connected to the Y-axis guide rods 142 and is driven by the Y-axis power source 141 to move along the width of the carrier plate 102.

[0036] The X-axis guide rod and the Y-axis guide rod are respectively controlled to move relative to the positioning rod by the X-axis transfer assembly and the Y-axis transfer assembly to adjust the area of the first storage area enclosed by the X-axis guide rod, the Y-axis guide rod and the positioning rod. Specifically, when the X-axis guide rod and the Y-axis guide rod move to the extreme position in the direction close to the positioning rod, that is, Figure 6 The position shown can be used to define the minimum area of the product; when the X-axis guide rod and the Y-axis guide rod move away from the positioning rod to the limit position, that is, Figure 5 The position shown can be used to limit products of larger length; when the Y-axis guide rod moves to the limit position close to the positioning rod, that is, Figure 2 The position shown can be used to define a medium-sized product.

[0037] Furthermore, a lifting mechanism 15 is connected between the base plate 10 and the carrier plate 102. This mechanism drives the carrier plate 102 toward the top of the positioning rod 11. The lifting mechanism may include a pneumatic cylinder, an electric cylinder, or other components capable of linear motion, though the specifics are not limited here. After products are stacked and placed on the carrier plate, the lifting mechanism is activated to drive the carrier plate toward the top of the positioning rod, facilitating product unloading.

[0038] like Figures 1 to 6 As shown, the frame 100 is also provided with a second storage unit 2, which is mounted on the second support frame 32 of the frame 100. The second storage unit 2 includes a set of second storage areas 201, and the area of the second storage areas 201 is different from that of the first storage areas 101. By dividing the frame into areas for storing products of different specifications and designing the storage areas to be adjustable, the frame can simultaneously transport at least two products of different specifications, ensuring stability during the transport process while also improving the practicality and flexibility of the vehicle.

[0039] Further, such as Figure 2 or Figure 5 or Figure 6 As shown, there is at least one second support frame 32, and they are distributed along the X-axis. A limit block 321 is set on each second support frame 32. A group of limit blocks 321 are distributed in a rectangular shape and enclose the second storage area 201. The width of the second storage area 201 is always greater than the width of the first storage area 101. The specific width is equivalent to the width of the second support frame 32. The width of the second support frame 32 can be adjusted according to product requirements and is not limited here. The distance between a pair of limit blocks 321 arranged along the Y-axis direction is adjustable to accommodate products of different specifications; the pair of limit blocks 321 arranged along the Y-axis direction can achieve distance adjustment through known structures including but not limited to slide rails. In other embodiments, all of the limit blocks 321 can also be fixed on the second support frame 32.

[0040] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
