In addition, as shown in FIG. 7B , the limit hole 215 a on the transverse limit beam 215 can also be used to cooperate with the third assembly part 16 of the cargo to further limit the cargo 10 .

According to another embodiment of the present utility model, in order to further save the storage space of the goods, multiple layers of goods 10 can be placed in a combined pallet 20, and the adjacent two layers of goods can use the middle frame as shown in Figures 8A and 8B 300 for limit. A modular pallet 20 may include one or more intermediate shelves 300 that are structurally compatible with shelves disposed above and below it. As shown in FIG. 8A , the intermediate frame 300 includes at least one loading unit 340 and at least one limiting unit 350 . Wherein, the loading unit 340 includes a loading surface 341 for carrying cargo, and a limiting device 345 for restricting the movement of the cargo. The limiting unit 350 is corresponding to the load-carrying unit 140 of the bottom frame or the load-carrying unit 340 of another intermediate frame located below the middle frame 300 , so as to limit the movement of goods.

Here, the intermediate frame 300 includes a pair of side beams 312 parallel to each other, and a pair of side beams 314 parallel to each other and perpendicular to the side beams 312 . The intermediate frame 300 can also include one or more limit beams, such as a longitudinal limit beam 313 arranged parallel to the side longitudinal beam 312 or a transverse limit beam 315 arranged parallel to the side beam 314, etc., wherein the transverse limit beam 315 It can be arranged between the longitudinal beams 312 on both sides, and the longitudinal limit beam 313 can be arranged between the side beams 314 and the transverse limit beams 315 . In order to improve the structural strength of the top frame, one or more reinforcing beams, such as reinforcing beams 319 , may also be arranged on the intermediate frame 300 . The loading surface 341 may be formed by upper surfaces of a plurality of beams (including side longitudinal beams 312 , side beams 314 , and/or limit beams 313 , 315 , etc.) of the intermediate frame 300 . The limiting device 345 is fixed to the beam of the intermediate frame 300 , and may include a plurality of limiting columns 346 , and the limiting columns 346 are preferably fixed to the beam of the intermediate frame through a limiting seat 348 . Preferably, an elbow 347 is provided on the top of the limit post 346 to play a guiding role when loading and unloading goods, and improve the efficiency of transportation. The limit unit 350 may be defined by the side longitudinal beam 312 , the side cross beam 314 , and/or the limit beams 313 , 315 of the intermediate frame 300 . At least one pair of protruding parts 355 separated by a predetermined distance D2 are also provided on the limiting unit 350 for limiting the goods. Similarly, other limiting structures can also be provided on the limiting unit 350 to better limit the goods, for example, a limiting hole 315a is provided under the transverse limiting beam 315, as shown in FIG. 8B . However, it should be clear that any limiting structure such as a protrusion or a limiting hole may not be provided in the limiting unit 350 .

As shown in FIG. 9 , when the combined pallet box 20 is empty, the middle frame 300 can be placed between the top frame 200 and the bottom frame 100 to save the storage space of the pallet box. Similar to the top frame 200 , both ends of the side longitudinal beam 312 of the middle frame 300 extend outward from the ends of the side beam 314 to form an outer angle 370 with the side beam 314 . The position of the outer included angle 370 of the intermediate frame corresponds to the position of the bottom frame stopper 170, like this, when the intermediate frame 300 is placed on the bottom frame 100, the stopper 170 is just located in the space defined by the outer included angle 370, and with this The outer angles 370 cooperate to define the position of the intermediate frame 300 on the base frame 100 . The corner portion of the middle frame 300 is also provided with an upwardly protruding matching column 375, and its position corresponds to the position of the outer angle 270 of the top frame 200. Like this, when the middle frame 300 is placed on the bottom frame 100, the middle frame matching column 375 is just located in the space defined by the outer angle 270 of the top frame, and cooperates with the outer angle 270 to define the position of the top frame 200 on the middle frame 200 .

Of course, in actual use, a plurality of intermediate shelves 300 can be set in one pallet 20 to stack more layers of goods. Multiple intermediate racks can also be stacked on top of each other when the pallet is empty. At this time, the matching column 375 of the lower intermediate frame can cooperate with the outer angle 370 of the upper intermediate frame to limit the movement of the upper intermediate frame. When a plurality of intermediate shelves 300 are provided, the structure and position of the limiting device 345 can be properly designed so that the limiting devices of two adjacent layers of intermediate shelves will not interfere when pallets are stacked with no load.

Next, the steps of using the intermediate frame 300 to place multi-layer goods will be described in detail. First, as shown in FIG. 10 , the intermediate frame 300 is placed on the second assembly portion 14 of the cargo 10, so that the spacing unit 350 of the intermediate frame 300 cooperates with the third assembly portion 16 of the cargo 10, so as to limit the distance between the cargo 10 and the cargo 10. Relative movement of the intermediate frame 300 . Preferably, the third assembly portion 16 of the cargo 10 is disposed between a pair of protrusions 355 of the intermediate frame limiting unit 350 , so that the movement of the cargo is further restricted by the cooperation of the protrusions 355 and the third assembly portion 16 . Similar to the limiting hole 215a of the top frame, the limiting hole 315a of the middle frame can also be used to cooperate with the third assembly part 16 of the cargo to better limit the cargo 10, which will not be repeated here.

Next, as shown in FIG. 11 , another layer of goods is placed on the intermediate frame 300 . The goods 10 are placed on the loading surface 341 of the loading unit of the middle shelf; the limiting device 345 of the loading unit 340 cooperates with the first assembly part 11 of the loading, thereby restricting the movement of the loading 10 . Here, the limiting device 345 cooperates with the outer side of the bottom of the cargo, that is, the limiting device 345 surrounds the cargo. However, it should be clear that similar to the limiting device 145 of the bottom frame 100, the limiting device 345 of the intermediate frame 300 can also be designed to cooperate with other parts of the cargo, and the limiting device 345 can be other suitable structures, such as One-piece structure, etc. In addition, the loading surface 341 can be a flat structure, or a curved structure corresponding to the structure and shape of the cargo. Finally, a top shelf 200 is placed on the uppermost cargo, as shown in FIG. 12 . The placement process of the top shelf 200 is similar to the above, and will not be repeated here. Preferably, in order to ensure the reliability of goods stacked on the pallet, the bottom frame 100 and the top frame 200 can be relatively fixed by using the binding strap 40 , as shown in FIG. 13 .

Since the upper surface of the top frame 200 and the lower surface of the bottom frame 100 are substantially flat, a combined pallet 20 can be placed on another combined pallet 20 when the combined pallet 20 is empty or loaded. Above to achieve mutual stacking, and the goods will not be squeezed after stacking. Preferably, a stacking positioning device 80 may be provided on the combined pallet 20, so as to facilitate mutual positioning of the pallets after stacking, so as to better ensure the safety of stacking. Next, taking an empty combined pallet as an example, the situation of using the stacking positioning device 80 to perform stacking and positioning will be described. As shown in FIG. 14 , the stacking positioning device 80 includes a stacking column 280 that is arranged on the top frame 200 and protrudes upward from the upper surface of the top frame 200 , and a stacking column 280 that is arranged on the bottom frame 100 and corresponds to the stacking column 280 The stacking hole 180. When two combined pallets are stacked on each other, the stacking column 280 of the lower combined pallet is limited in the stacking hole 180 of the upper combined pallet, thereby avoiding the pairing of the upper and lower pallets. Move to realize stacking positioning. After the pallet is loaded with goods, its stacking state is similar to that when it is empty, so I won't repeat it here.

Here, the structure of the combined pallet of the present invention and the method of loading goods using the pallet are described by taking the goods shown in Figures 1 and 2 as examples, but it should be understood that the combined pallet of the present invention can also be used for shipment Other irregularly shaped goods. By properly setting the size and structure of multiple loading units and/or position-limiting units on each rack in the combined pallet, goods of different structures can be loaded in one combined pallet. In addition, it should also be understood that, depending on the structure of the goods, the structures of different intermediate frames may not be exactly the same, and the load-carrying unit and the limit unit on the same intermediate frame do not have to correspond one-to-one; The position-limiting units on the upper shelf correspond to each other, and the position-limiting units on the middle shelf correspond to the position-limiting units on the lower shelf.

It should be pointed out that although the present utility model has been described through the above-mentioned embodiments, the present utility model can also have other various embodiments. Under the premise of not departing from the spirit and scope of the present utility model, those skilled in the art can obviously make various corresponding changes and deformations to the present utility model, but these changes and deformations should all belong to the appended claims of the present utility model and within the scope of its equivalents.
