Abstract
Description
Technical Field
[0001] This utility model relates to the field of pallet technology, and in particular to a pallet structure for stacking cardboard boxes. Background Technology
[0002] Pallets are bases designed for convenient placement and shipping of loose items. They are generally square and, by material, include wooden pallets and plastic pallets. Taking cardboard boxes as an example, after processing in the factory, the boxes are flat. Multiple boxes are stacked and bundled together using a strapping machine. Then, a robotic arm places the bundled boxes onto a pallet, and a forklift moves the pallet to another location. The problem is that the stacking height of the boxes on the pallet cannot be too high, otherwise they may collapse during the transfer process; if the stacking height is too low, the number of boxes transferred at one time is too small, resulting in low efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a pallet structure for stacking cardboard boxes, which can improve the stability of cardboard box stacking.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A pallet structure for stacking cardboard boxes includes a pallet, four baffles, and four locking components.
[0006] The top surface of the pallet has a cross-shaped groove, and there are receiving slots below the four ends of the cross-shaped groove;
[0007] The four baffles are located in the four sections of the cross-shaped groove, and the outer ends of the baffles are rotatably connected to the pallet.
[0008] The locking element is located in the mounting groove below the receiving groove. The mounting groove has a limiting groove that penetrates the pallet. The locking element includes a limiting block, a spring, and a pressure rod. The limiting block slides up and down in the mounting groove. The bottom of the limiting block is connected to the spring. The pressure rod slides in the limiting groove. The inner end of the pressure rod is connected to the limiting block. When the baffle is turned to the vertical position, the inner wall of the limiting block is in close contact with the outer wall of the baffle, and the inner wall of the baffle is in close contact with the pallet.
[0009] Furthermore, the outward-facing side of the top of the limiting block is designed as a slope.
[0010] Furthermore, it also includes four extension plates. Both the extension plates and the baffles are U-shaped plates. The two sections of the extension plates are inserted into the baffles. The two outer walls of the inner end of the baffles are provided with insertion holes. The two outer walls of the outer end of the extension plates are provided with buttons. When the button is located in the corresponding insertion hole, it is used to fix the extension plate.
[0011] Furthermore, each of the four sections of the cross-shaped groove is equipped with a support bar. When the baffle is located in the cross-shaped groove, the support bar is located in the corresponding baffle.
[0012] Furthermore, the top surfaces of the support strip, baffle, and pallet are flush.
[0013] The beneficial effects of this utility model are as follows: when the baffle is in a horizontal state, it can be stored in the cross-shaped groove without taking up space; when the baffle is in a vertical state, it is fixed by a locking device, which has a clever structure and is easy to operate; the baffle can limit the position of the cartons stacked on the pallet, which helps to improve the stability of the cartons stacking and thus increase the height of the cartons stacking.

[0020] like Figure 1 , Figure 2 As shown, this embodiment provides a pallet structure for stacking cardboard boxes, including a pallet 1, four baffles 2, and four locking components 3.
[0021] Specifically, such as Figure 1 , Figure 2 As shown, the top surface of the pallet 1 is provided with a cross-shaped groove 11, which divides the top surface of the pallet 1 into four rectangular areas. The four ends of the cross-shaped groove 11 are provided with receiving grooves 12.
[0022] Specifically, the four baffles 2 are located in the four sections of the cross-shaped groove 11, and the top surface of the baffles 2 is flush with the top surface of the pallet 1. The outer end of the baffles 2 is rotatably connected to the pallet 1. The outer end of the baffles 2 refers to the direction of the baffles 2 towards the outside of the pallet 1.
[0023] Specifically, such as Figure 1 , Figure 2As shown, the locking element 3 is located in the mounting groove 13 below the receiving groove 12. The mounting groove 13 has a limiting groove 14 that penetrates the pallet 1. The locking element 3 includes a limiting block 31, a spring 32, and a pressure rod 33. The limiting block 31 slides up and down in the mounting groove 13, and the top surface of the limiting block 31 is higher than the mounting groove 13. The spring 32 is located in the mounting groove 13, and the bottom of the limiting block 31 is connected to the spring 32. The pressure rod 33 slides in the limiting groove 14, and the inner end of the pressure rod 33 is connected to the limiting block 31. The function of the locking element 3 is to lock the baffle 2 when the baffle 2 is turned into a vertical state.
[0024] The method of use is as follows: Press down the pressure bar 33 with one hand to retract the limiting block 31 into the mounting groove 13, and turn the baffle 2 into a vertical position with the other hand. At this time, the inner wall of the baffle 2 is in close contact with the pallet 1. After releasing the pressure bar 33, the limiting block 31 rises from the mounting groove 13, and the inner wall of the limiting block 31 is in close contact with the outer wall of the baffle 2, thereby locking the baffle 2. After the other three baffles 2 are erected in the same way, the cartons can be stacked on the pallet 1. The baffles 2 play a limiting role, which helps to improve the stability of the cartons stacking, thereby increasing the height of the cartons stacking.
[0025] The above solution will be optimized as follows:
[0026] First, to facilitate turning the baffle 2 inside the cross-shaped groove 11 into a vertical position, such as... Figure 3 As shown, the outer end of the baffle 2 extends beyond the cross-shaped groove 11 by a certain distance, so that the person can work on the outer end of the baffle 2.
[0027] Secondly, before the baffle 2 turns to the vertical position, it is necessary to manually press down the pressure rod 33. To save on operations, such as... Figure 2 As shown, in this embodiment, the side of the limiting block 31 facing outward is set as an inclined surface. This eliminates the need for manual downward pressing of the pressure rod 33. During the process of turning the baffle 2 into a vertical state, the baffle 2 can automatically press the limiting block 31 downward, causing the limiting block 31 to retract into the mounting groove 13.
[0028] To further increase the stacking height of cardboard boxes, such as Figure 4 , Figure 5 As shown, this embodiment also includes four extension plates 4, each extension plate 4 corresponding to one baffle 2. Both the extension plates 4 and baffles 2 are U-shaped plates. Each of the two sections of the baffle 2 has a slot. The two sections of the extension plates 4 are inserted upside down into the slots of the baffle 2, as shown. Figure 5 , Figure 6As shown, both outer walls of the inner end of the baffle 2 are provided with insertion holes, and both outer walls of the outer end of the extension plate 4 are provided with buttons 41. When the button 41 is in the corresponding insertion hole, it is used to fix the extension plate 4. When the button 41 is pressed manually, it can be retracted into the insertion hole so that the extension plate 4 can be reinserted into the slot of the baffle 2. It should be noted that the button 41 is a conventional structure, and its structure and principle will not be described in detail here.
[0029] When the baffle 2 is in a vertical position, the cross-shaped groove 11 lacks support for the carton. This embodiment takes the following measures: Figure 3 , Figure 4 As shown, each of the four sections of the cross-shaped groove 11 is provided with a support bar 15. As mentioned earlier, the extension plate 4 and the baffle 2 are both set as U-shaped plates. The two sections of the extension plate 4 are inserted into the slots of the baffle 2. Therefore, when the baffle 2 is stored in the cross-shaped groove 11, the support bar 15 is located in the corresponding baffle 2, and the top surfaces of the support bar 15, the baffle 2, and the pallet 1 are flush.
[0030] This embodiment is provided with four baffles 2. When the baffles 2 are in a horizontal state, they are stored in the cross-shaped grooves 11. When the baffles 2 are in a vertical state, they can limit the stacked cartons on the pallet 1, which helps to improve the stability of the carton stack and thus increase the height of the carton stack. In addition to the four baffles 2, this embodiment also provides four extension plates 4. When the extension plates 4 are not in use, they can be retracted into the baffles 2. When it is necessary to further increase the height of the baffles 2, it is only necessary to pull the extension plates 4 upward until the button 41 is located in the corresponding socket, thereby fixing the extension plates 4.
[0031] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
