Description

Technical Field

[0001] This utility model relates to the field of plastic pallet technology, and in particular to a plastic pallet with good stability. Background Technology

[0002] Plastic pallets are core unitized equipment in modern logistics warehousing. They are mainly made of high-density polyethylene and polypropylene through injection molding. Common structural styles include nine-legged and cross-shaped. They can be adapted to forklifts, racks and other loading and unloading storage tools to realize the collection, handling and stacking of goods.

[0003] Most existing plastic pallets lack reinforced support legs and stress-distribution structures. Plastic pallets without reinforced support legs and stress-distribution structures have defects such as weak load-bearing capacity and uneven stress distribution. They are prone to local dents, deformations or even cracks during stacking or forklift operations, making them unsuitable for heavy goods and high-frequency turnover scenarios.

[0004] Some heavy-duty pallets have reinforced support legs and stress-distributing structures. The reinforcement structure of these pallets is mainly made of one-piece injection molding, while some use bolts or welding to fix the pallet to the support leg reinforcement structure. The one-piece molding reinforcement structure has the problems of complex process and difficult mold opening, while bolts or welding will make assembly more troublesome and waste manpower.

[0005] Furthermore, most existing plastic pallets lack abrasion- and cut-resistant protective layers on the top and bottom. After repeated use, the top of the plastic pallet will be worn down by the goods, and the support legs will be worn down by the ground, resulting in a short service life. Some plastic pallets with protective layers simply have the rubber layer bonded directly to the pallet without a composite adhesive and snap-fit ​​connection structure. If strong adhesive is used for bonding, the wear-resistant protective layer will be difficult or impossible to replace. If removable adhesive is used for bonding, the protective layer is prone to peeling and curling.

[0006] Therefore, there is an urgent need to provide a plastic pallet with good stability to solve the above problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a plastic pallet with good stability.

[0008] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a plastic pallet with good stability, including a pallet mechanism, a bottom beam mechanism, a top protective layer and a bottom protective layer, wherein the pallet mechanism includes a pallet body, the pallet body is integrally formed with a first reinforcing rib, and the top of the pallet body is also provided with a plurality of first locking holes; The bottom of the pallet mechanism is engaged with a bottom beam mechanism, which includes multiple insert blocks, and the outer wall of each insert block is integrally formed with multiple locking blocks. The top of the pallet mechanism is bonded with a top protective layer, and the bottom of the bottom beam mechanism is fitted with a bottom protective layer.

[0009] The present invention is further configured such that: a plurality of support feet are fixed at the bottom of the tray body, and a plurality of second locking holes are provided on the outer wall of the support feet.

[0010] Through the above technical solution, the pallet body can be made of high-strength engineering plastic material, which has high strength, and the first reinforcing rib further improves the strength of the pallet body.

[0011] The present invention is further configured such that: the insert block is inserted into the inner side of the support foot, the top of the card block is integrally formed with a sloping structure, and a connecting plate is fixed between the insert blocks.

[0012] With the above technical solution, the bottom beam mechanism is set with three parts. When the insert block is inserted upward into the inside of the support foot, the locking block will lock into the second locking hole, thereby preventing the bottom beam mechanism from separating from the pallet mechanism. It can be quickly assembled without bolt fixing or welding. The connecting plate and the locking block connect the three support feet, thereby reinforcing the support feet, distributing the force on the support feet, preventing their deformation, and effectively reducing the pressure of the device on the ground.

[0013] The present invention is further configured such that: two connecting beams are integrally formed on the connecting plate, and multiple second reinforcing ribs are integrally formed on the inner and outer sides of the connecting beams; and a locking hole is provided at the bottom of the connecting plate.

[0014] Through the above technical solutions, both the connecting plate and the second reinforcing rib effectively improve the strength of the connecting plate, thereby making the connecting plate more effective in reinforcing the support foot.

[0015] The present invention is further configured such that: the top protective layer includes a protective outer layer that is fitted onto the top of the tray body, and the inner part of the protective outer layer is wrapped with a tensile layer and an elastic buffer layer.

[0016] Through the above technical solution, the top protective layer can effectively protect the top of the device, preventing it from being worn, dented, or scratched by sharp objects during frequent use, thereby effectively improving the service life of the device.

[0017] The present invention is further configured such that: the protective outer layer is made of modified polyurethane, the tensile layer is made of steel wire mesh or stainless steel wire mesh, and the elastic buffer layer is made of nitrile rubber.

[0018] Through the above technical solutions, the protective outer layer made of modified polyurethane material has strong wear resistance, which can effectively prevent the surface of the device from being worn. The tensile layer made of wire mesh material can effectively prevent the top protective layer from tearing and tensile deformation under high load and frequent friction. It can also play a good role in preventing cuts and punctures, thereby preventing sharp objects such as cargo support legs and wooden box nails from cutting and puncturing the surface of the device. The elastic buffer layer can effectively absorb and disperse the impact force of the cargo on the device, thereby improving the service life of the device.

[0019] The present invention is further configured such that: an adhesive layer is attached to the bottom of the top protective layer, and multiple buckles are integrally fixed to the bottom end of the top protective layer, the position, number and specifications of the buckles being matched with the first buckle hole.

[0020] With the above technical solution, the top protective layer is fixed by snap-fitting to the first snap-fit ​​hole and is also bonded by an adhesive layer. This double fixation can effectively prevent the top protective layer from peeling off. The adhesive layer can be removable. When the top protective layer is worn, it can be replaced separately by tearing off the top protective layer and pulling out the snap-fit.

[0021] The present invention is further configured such that: the structure of the bottom protective layer is the same as that of the top protective layer, and the top of the bottom protective layer is also provided with an adhesive layer and a buckle, and the position, number and specifications of the buckle on the top of the bottom protective layer are matched with the buckle holes at the bottom of the connecting plate.

[0022] Through the above technical solution, the bottom protective layer, with the same protective structure as the top protective layer, can prevent the ground from causing wear on the bottom beam mechanism, and can also be replaced separately.

[0023] The beneficial effects of this utility model are as follows: 1. By setting up a pallet mechanism and a bottom beam mechanism, this utility model enables the device to effectively reinforce and distribute the force on the pallet support legs, thereby improving the load-bearing capacity and stability of the device, and its reinforcement structure is easy to install; 2. By setting up a top protective layer and a bottom protective layer, this utility model effectively prevents the top and bottom of the device from being worn or scratched by goods or the ground, and the protective layer can be easily replaced, thus improving the service life of the device.

[0027] Please see Figures 1-6 A stable plastic pallet includes a pallet mechanism 1, a bottom beam mechanism 2, a top protective layer 3, and a bottom protective layer 6. The pallet mechanism 1 includes a pallet body 101, on which a first reinforcing rib 102 is integrally formed. The top of the pallet body 101 is also provided with multiple first locking holes 103. The bottom of the pallet body 101 is fixed with multiple supporting feet 104. The outer wall of the supporting feet 104 is provided with multiple second locking holes 105. The pallet body 101 can be made of high-strength engineering plastic material, which has high strength. The first reinforcing rib 102 further improves the strength of the pallet body 101.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, the bottom of the pallet mechanism 1 is engaged with a bottom beam mechanism 2. The bottom beam mechanism 2 includes multiple insert blocks 201. Multiple locking blocks 202 are integrally formed on the outer wall of each insert block 201. The insert blocks 201 are inserted into the inner side of the support leg 104. The top of each locking block 202 is integrally formed with a slope structure 203. A connecting plate 204 is fixed between the insert blocks 201. The insert blocks 201 are inserted into the inner side of the support leg 104. The top of each locking block 202 is integrally formed with a slope structure 203. Two connecting beams 206 are integrally formed on the connecting plate 204. Multiple second reinforcing ribs 205 are integrally formed on both the inner and outer sides of the connecting beams 206. A locking hole is provided at the bottom of the connecting plate 204. The bottom beam mechanism 2 has three components. When the insert block 201 is inserted upwards into the inner side of the support leg 104... When the locking block 202 engages with the second locking hole 105, it prevents the bottom beam mechanism 2 from separating from the pallet mechanism 1. Quick assembly is possible without bolts or welding. The connecting plate 204 and the locking block 202 connect the three support legs 104, thereby reinforcing the support legs 104, distributing the force on the support legs 104 to prevent deformation, and effectively reducing the pressure of the device on the ground. Both the connecting plate 204 and the second reinforcing rib 205 effectively improve the strength of the connecting plate 204, resulting in better reinforcement of the support legs 104.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, a top protective layer 3 is adhered to the top of the pallet mechanism 1. The top protective layer 3 includes a protective outer layer 301 that is attached to the top of the pallet body 101. The protective outer layer 301 contains a tensile layer 302 and an elastic buffer layer 303. The protective outer layer 301 is made of modified polyurethane, the tensile layer 302 is made of steel wire mesh or stainless steel wire mesh, and the elastic buffer layer 303 is made of nitrile rubber. The top protective layer 3 effectively protects the top of the device, preventing it from being worn, dented, or scratched by sharp objects during frequent use. The modified polyurethane outer protective layer 301 has strong wear resistance, which can effectively prevent surface wear of the device. The steel wire mesh tensile layer 302 can effectively prevent the top protective layer 3 from tearing and tensile deformation under high load and frequent friction. It can also play a good role in preventing cuts and punctures, thus avoiding sharp objects such as cargo legs and wooden box nails from cutting and puncturing the surface of the device. The elastic buffer layer 303 can effectively absorb and disperse the impact force of cargo on the device, thereby improving the service life of the device.

[0030] like Figure 1 , Figure 5and Figure 6 As shown, an adhesive layer 4 is attached to the bottom of the top protective layer 3. Multiple clips 5 are integrally fixed to the bottom end of the top protective layer 3. The position, number, and specifications of the clips 5 match the first locking hole 103. The top protective layer 3 is secured to the first locking hole 103 via the clips 5 and bonded by the adhesive layer 4. This double-fixing effectively prevents the top protective layer 3 from peeling off. The adhesive layer 4 can be removable. When the top protective layer 3 is worn, it can be replaced individually by tearing off the top protective layer 3 and pulling out the clips 5. A bottom protective layer 6 is attached to the bottom of the bottom beam mechanism 2. The structure of the bottom protective layer 6 is the same as that of the top protective layer 3, and the top of the bottom protective layer 6 is also... The bottom protective layer 6 is equipped with an adhesive layer 4 and clips 5. The position, number, and specifications of the clips 5 on the top of the bottom protective layer 6 match the clip holes on the bottom of the connecting plate 204. The structure of the bottom protective layer 6 is the same as that of the top protective layer 3, and the top of the bottom protective layer 6 is also equipped with an adhesive layer 4 and clips 5.
