[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 , Figure 3 and Figure 4, an embodiment provided by the present utility model: an up-and-down combined plastic pallet, including a pallet 1, which is made by injection molding to ensure the overall stability of the pallet 1. Two positioning columns 2 are fixedly connected to one side of the bottom of the pallet 1, and positioning holes 3 are provided on the side wall of the positioning columns 2. A support column 4 is fixedly connected to the other side of the bottom of the pallet 1. Two guiding grooves 5 are provided on one side inside the pallet 1, and two positioning grooves 6 are provided on the other side inside the pallet 1. By inserting the support column 4 of the top pallet into the guiding groove 5, and then inserting the positioning column 2 of the top pallet into the positioning groove 6, the cooperation between the groove and the column is used to limit the upper and lower pallets 1, ensuring that there is no horizontal movement tendency between the two combined plastic pallets, ensuring the stability of the upper and lower pallets 1 after combination, and further improving the stability of the pallet 1 when carrying goods. An installation shell 7 is fixedly connected to the inner wall of the positioning groove 6. A connecting pin 8 is slidably connected inside the installation shell 7. A slider 9 is fixedly connected to one side of the outer periphery of the connecting pin 8. A spring 10 is sleeved on the other side of the outer periphery of the connecting pin 8. A thrust towards the inside of the pallet 1 is applied to the slider 9 through the spring 10, so that the slider 9 applies a thrust towards the inside of the positioning groove 6 to the connecting pin 8, and then the connecting pin 8 is tightly inserted into the positioning hole 3, locking and fixing the positioning column 2 inside the positioning groove 6, and completing the assembly between the upper and lower pallets 1. Four anti-slip components for preventing materials from slipping are installed on the outer wall of the pallet 1.

[0032] Refer to Figure 1 , Figure 3 and Figure 4A plurality of weight-reducing holes 11 are provided in the middle of the pallet 1. The weight-reducing holes 11 can effectively reduce the weight of the plastic pallet itself, making it more convenient to pick up and transport the pallet without affecting the supporting strength of the plastic pallet itself. The outer side of the support column 4 is slidably connected to the inside of the guide groove 5, and the outer side of the positioning column 2 is slidably connected to the inside of the positioning groove 6. The cooperation between the support column 4 and the guide groove 5, and the positioning groove 6 and the positioning column 2 ensures the stability of the upper and lower pallets 1 after splicing. The outer side of the slider 9 is slidably connected to the inside of the mounting shell 7. One end of the connecting pin 8 passes through the pallet 1 and is inserted into the inside of the positioning hole 3. The cooperation between the slider 9 and the mounting shell 7 prevents the connecting pin 8 from being completely pulled out of the outside of the mounting shell 7 when pulling it. At the same time, the positioning column 2 is locked and fixed in the positioning groove 6 by means of the clamping between the connecting pin 8 and the positioning hole 3. One end of the spring 10 is fixedly connected to the middle of the slider 9, and the other end of the spring 10 is fixedly connected to the inner wall of the mounting shell 7. The spring 10 is in a compressed state, and then the spring 10 applies a thrust to the connecting pin 8 to ensure that the connecting pin 8 does not escape from the inside of the positioning hole 3. The pallet 1 is provided with longitudinal and transverse reinforcing ribs 12 inside, and the longitudinal and transverse reinforcing ribs 12 penetrate the inside of the weight-reducing hole 11. When the pallet 1 is injection molded, the longitudinal and transverse reinforcing ribs 12 prepared in advance are placed in the injection mold. When the injection molding of the pallet 1 is completed, the longitudinal and transverse reinforcing ribs 12 are directly covered inside the pallet 1. The longitudinal and transverse reinforcing ribs 12 can effectively improve the structural strength of the pallet 1, delay the serious deformation of the pallet 1 after long-term use, and the setting of the longitudinal and transverse reinforcing ribs 12 can further prevent the pallet 1 from suddenly breaking when bearing.

[0033] Reference Figure 1 and Figure 2 The anti-drop assembly includes an anti-drop plate 14, and adjustment grooves 15 are provided on both sides of the anti-drop plate 14. An adjustment bolt 16 is slidably connected inside the adjustment groove 15. One end of the adjustment bolt 16 passes through the adjustment groove 15 and is threadedly connected inside the pallet 1. Four limiting grooves 13 are provided on the outer wall of the pallet 1, and the outer side of the anti-drop plate 14 is slidably connected inside the limiting groove 13. When the goods are loaded onto the pallet 1, the worker loosens the adjusting bolt 16 to disengage the locking of the anti-drop plate 14, so that the anti-drop plate 14 can adjust its own height with the cooperation of the adjusting groove 15, lift the anti-drop plate 14 to the highest position, and then tighten the adjusting bolt 16 to lock it inside the limiting groove 13, so that the part of the anti-drop plate 14 extending from the top of the pallet 1 can effectively limit the goods and prevent the goods from falling.

[0034] Working principle: When it is necessary to carry heavier goods, a plastic pallet is placed upside down on the ground, and then the bottom of another plastic pallet is buckled on the inverted pallet, so that the support column 4 of the top pallet is inserted into the guide groove 5 of the bottom pallet, and the top positioning column 2 is inserted into the bottom positioning groove 6. At this time, the two pallets are preliminarily connected together, and then the worker pulls the handle on the connecting pin 8 to pull the connecting pin 8 out from the inside of the mounting shell 7 until the connecting pin 8 is completely pulled into the inside of the mounting shell 7. At this time, the slider 9 moves with the connecting pin 8 to compress the spring 10 inside the mounting shell 7. At this time, the positioning column 2 completely falls into the positioning groove 6, and then the pulled connecting pin 8 is released, so that the spring 10 is released from the lock and reset, and then the slider 9 is pushed to move inside the mounting shell 7. The connecting pin 8 is reset and inserted into the positioning hole 3 through the slider 9, and the positioning column 2 is locked inside the positioning groove 6. The buckle assembly between the two pallets is completed, so that the assembled pallet obtains more support structure, and then ensures that the pallet is more stable when carrying heavier goods.

[0035] After placing the goods on the pallet, the worker loosens the adjusting bolt 16, then pushes the anti-slip plate 14 upward to make it slide upward from the limiting groove 13, and then extend to and exceed the top plane of the pallet 1, and then retightens the loosened adjusting bolt 16, so that the anti-slip plate 14 is locked and fixed in the limiting groove 13 under the pressure of the adjusting bolt 16, and the four sides of the pallet are limited and protected by the anti-slip plate 14 to prevent the goods from sliding off the pallet.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
