Description

Technical Field

[0001] The utility model relates to the field of pallets, belonging to warehousing and logistics tools, and specifically is a Sichuan-shaped pallet with a top and bottom cover. Background Art

[0002] Plastic pallets are widely used in the logistics and warehousing industries. Compared to traditional wooden pallets, plastic pallets offer advantages such as ease of handling, corrosion resistance, and earthquake resistance. Plastic pallets with built-in covers can also reduce damage to goods during transportation and storage, lowering logistics and warehousing costs. In today's logistics and warehousing sectors, plastic pallets have replaced wooden pallets as the most widely used storage and logistics tool.

[0003] Plastic pallets are manufactured using two methods: blow molding and injection molding. Blow-molded pallets allow for greater blanking and can carry heavier loads. However, during the blow molding process, the legs often develop uneven surfaces, resulting in a low yield. Furthermore, the legs of conventional plastic pallets can easily deform under the weight of heavier goods, shortening their service life. Utility Model Content

[0004] Compared with the traditional plastic pallet, the utility model has a lining steel pipe and a protective cover structure for protecting the lining steel pipe in the supporting feet, which solves the problems raised in the background technology.

[0005] The technical solution adopted by this utility model is:

[0006] A Sichuan-shaped pallet with a top and bottom cover comprises a cover plate, a pallet body and supporting legs. The pallet body comprises a pallet panel and a pallet base. The supporting legs are arranged at the bottom of the pallet base. An inner lining steel pipe is provided in the supporting legs. A protective cover is provided on the outer side of the inner lining steel pipe. The protective cover is used to protect the inner lining steel pipe.

[0007] The cross section of the protective sleeve is wavy, and the protective sleeve includes a raised section and a flat section. The raised section of the protective sleeve fits the outer side of the lining steel pipe.

[0008] A positioning hole is provided on the surface of the lining steel pipe that contacts the protective sleeve.

[0009] The Sichuan-shaped top and bottom cover tray is further provided with a connector, which is used to connect the support legs and the tray body, and the support legs are provided with a connector mounting hole.

[0010] The cover plate is provided with a limiting strip, and the support leg is provided with a limiting groove. The support leg can be arranged above the cover plate through the cooperation of the limiting groove and the limiting strip.

[0011] The limiting strip includes a second limiting strip and a first limiting strip, and the length of the first limiting strip is the same as the length of the limiting groove.

[0012] The periphery of the tray panel is provided with a lower side groove, and the periphery of the inner side of the cover plate is provided with an upper side groove.

[0013] The protective cover is made of plastic material by injection molding.

[0014] A plurality of square grooves are provided in the tray panel, and the contours of the square grooves are in conformity with the tray base.

[0015] The beneficial effects of the present invention are as follows: the pressure resistance of the pallet is enhanced by setting the inner lining steel pipe, and a protective cover is set on the inner lining steel pipe, so that the support legs are flatter after blow molding, avoiding the inner lining steel pipe being exposed to the outside after blow molding, making the support legs and the pallet more beautiful as a whole, and also extending the service life of the inner lining steel pipe and the support legs.

DETAILED DESCRIPTION

[0025] The structure, function, usage and beneficial effects of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 A Sichuan-shaped pallet with a top and bottom cover is modularly arranged. The pallet includes a cover plate 1, a pallet body 2, and support legs 3. The cover plate 1, the pallet body 2, and the support legs 3 are all formed by a blow molding process. The cover plate 1 is detachably arranged above the pallet body 2. The support legs 3 are fixedly arranged below the pallet body 2. To facilitate forklift transportation, the support legs of the top and bottom cover pallet are arranged in a Sichuan shape, and each support leg is also provided with two square holes, so that the forklift can enter from four directions when transporting goods.

[0027] like Figure 2 、 Figure 3 The support leg 3 is provided with an inner lining steel pipe 4, and a protective cover 5 is provided on the outside of the inner lining steel pipe 4. The provision of the inner lining steel pipe 4 enhances the compressive strength of the support leg 3, so that when the support leg 3 is provided at the bottom of the pallet, the pallet can hold heavier goods. At the same time, the enhanced compressive strength also prolongs the service life of the support leg 3. The support leg 3 is usually processed by a blow molding process. If the inner lining steel pipe 4 is simply provided in the support leg 3 and then the support leg 3 is blow-molded and sealed as a whole, it is easy for the blow molding to be uneven during the processing process, resulting in partial leakage of the inner lining steel pipe 4. During daily use, the leaked inner lining steel pipe 4 is prone to various losses due to various factors in the external environment, which reduces the overall service life of the support leg 3.

[0028] In order to solve this problem, the present invention not only provides the lining steel pipe 4 but also adds a protective sleeve 5 on the lining steel pipe 4. The lining steel pipe 4 is provided in the embedding groove 33 at the bottom of the support leg 3, while the protective sleeve 5 is sleeved on the outside of the lining steel pipe 4. The protective sleeve 5 is made of plastic injection molding, and the cross-section of the protective sleeve 5 is wavy. The structure of the protective sleeve 5 includes a raised section and a flat section. When the protective sleeve 5 is sleeved on the outside of the lining steel pipe, the inner side surface of the raised section of the protective sleeve 5 fits tightly with the outer side of the lining steel pipe 4, isolating the lining steel pipe 4 from the external environment. The provision of the flat section of the protective sleeve 5 limits the position of the protective sleeve 5 and the lining steel pipe 4 in the embedding groove 33, so that the protective sleeve 5 and the lining steel pipe 4 can be flatly and firmly embedded in the embedding groove 33. By providing the protective sleeve 5, the support leg 3 can ensure the flatness of the blow molding during the blow molding process, avoiding that part of the lining steel pipe 4 is still exposed to the outside after blow molding. The lining steel pipe 4 can be completely wrapped in the structure of the support leg 3, which extends the service life of the lining steel pipe 4 and the support leg 3 and enhances the overall aesthetics of the support leg 3 and the pallet.

[0029] When blow molding the support leg 3, the lining steel pipe 4 and the protective cover 5 need to be vertically arranged in the mold of the support leg 3. In order to prevent the position deviation of the lining steel pipe 4 and the protective cover 5 during the blow molding process, Figure 4 A positioning hole 41 is provided on the surface of the inner lining steel pipe 4 that contacts the protective sleeve 5, and a positioning pin 51 is provided at a position corresponding to the positioning hole 41 of the protective sleeve 5. The shape of the inner part of the positioning pin 51 matches the positioning hole 41 and is used to fix the inner lining steel pipe 4. The outer part of the positioning pin 51 is used to fix the protective sleeve 5 and the inner lining steel pipe 4 connected as one on the mold of the support leg 3. Before the support leg 3 is blow-molded, the pre-connected inner lining steel pipe 4 and the protective sleeve 5 are fixed at the corresponding embedding groove 33 of the mold of the support leg 3. The positioning pin 5 cooperates with the corresponding fixing point on the mold to stabilize the position of the inner lining steel pipe 4 and the protective sleeve 5. After the blow molding of the support leg 3 is completed, it is only necessary to cut off the outer part of the positioning pin 51 to obtain a support leg 3 with a smooth surface and a stable structure.

[0030] like Figure 5 、 Figure 6 The pallet body 2 includes a pallet base 22, and the support leg 3 is arranged below the pallet base 22. A connector mounting hole 31 is provided in the support leg 3, and the support leg 3 is fixedly connected to the pallet base 22 through the connector 6. In the utility model, the connector 6 includes a male buckle and a female buckle, the female buckle is provided at the bottom of the pallet base 22, and the male buckle is provided at the connector mounting hole 31. When the pallet body 2 and the support leg 3 are blow-molded separately, the female buckle is pre-set at the corresponding position of the mold of the pallet body 2, and the male buckle is provided at the corresponding position of the mold of the support leg 3. After the blow molding is completed, the pallet body 2 and the support leg 2 can be connected through the buckling connection relationship between the male buckle and the female buckle. Through the provision of the connector 6, the pallet body 2 and the support leg 3 respectively made by blow molding have a structural strength that exceeds that of a pallet made by integral injection molding after being connected, which saves costs while also increasing the life of the product.

[0031] like Figure 6 , the present invention can be stacked when no goods are loaded. A limit strip is provided on the cover 1, and corresponding to the limit strip, the support leg 3 is provided with a limit groove 32. Each Sichuan-shaped top and bottom cover pallet can be set above another Sichuan-shaped top and bottom cover pallet through the cooperation of the limit groove 32 and the limit strip. As a preferred embodiment of the present invention, the limit strip includes a first limit strip 11 arranged horizontally and a second limit strip 12 arranged vertically. The first limit strip 11 is used to cooperate with the limit groove 32 to limit the position of the support leg 3 in the longitudinal direction. The second limit strip 12 is used to limit the position of the support leg 3 in the transverse direction.

[0032] like Figure 7Before storing or transporting goods, the cover plate 1 is separated from the pallet body 2, and the goods can be placed between the cover plate 1 and the pallet body 2. The pallet body 2 includes a pallet panel 21, which is used to carry goods. As a preferred embodiment of the present invention, the outer periphery of the pallet panel 21 is provided with a lower edge groove 212 for matching the apron, and the outer periphery of the cover plate 1 is also provided with an upper edge groove 13 for matching the apron. After the goods are placed on the pallet panel 21, the apron is installed between the cover plate 1 and the pallet body 2, and the preparations for storing or transporting the goods are completed.

[0033] Because the "Chuan"-shaped pallet with a top and bottom lid is modular in design, the pallet body 2 can function as a conventional pallet for loading, unloading, storage, and transporting cargo without the cover panel 1 and legs 3. The pallet panel 2 is provided with a square groove 211, the shape of which aligns with the shape of the pallet base 22. The square groove 211 and the base 22 allow the pallets 2 to be stacked together, facilitating storage and stacking when no cargo is loaded.

[0034] Furthermore, to facilitate the disassembly and transportation of the top and bottom cover pallets, the cover panels 1 can be stacked on their own. The inner side of the cover panel 1, the side that contacts the cargo, is provided with several grooves. These grooves correspond to the retaining bars on the outer side of the cover panel 1. When the cover panels 1 are stacked individually, each groove engages with its corresponding retaining bar, ensuring that the cover panels 1 remain stable and flat after stacking.

[0035] The terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "horizontal", "longitudinal", etc. used in the above description to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings.
