[0023] like Figure 1 、 Figure 2, A U-shaped pallet and its connecting piece. Its structure includes a pallet body 1, support feet 3 and a connecting piece 2. The support feet 3 are installed at the bottom of the pallet body 1 through the connecting piece 2. In the present utility model, both the pallet body 1 and the support feet 3 are made by blow molding process. The blow molding process has more material feeding than the injection molding process, and the made pallet can carry heavier goods. There are three support feet 3 in total, and each support foot 3 is arranged in a U-shaped distribution at a uniform distance at the bottom of the pallet body 1. Two of the support feet 3 are arranged at the outer edge of the bottom of the pallet body 1, and the other support foot 3 is arranged at the central axis of the bottom of the pallet body 1. The U-shaped arrangement of the support feet facilitates the handling by a forklift and also enables the pallet to remain stable after carrying heavy objects. To meet the transportation and storage requirements of large goods, a cover plate 4 is generally added above the U-shaped pallet, and the cover plate 4 is used to cooperate with the pallet body 1 to form a transport box.

[0024] Such as Figure 3 , Figure 4 , The connecting piece 2 includes a female buckle part 21 and a male buckle part 22. The female buckle part 21 and the male buckle part 22 are respectively formed by injection molding process. The female buckle part 21 is in a frustum shape, and the male buckle part 22 is in a cage shape. The top of the male buckle part 22 is provided with a cage-shaped buckle 221, and the male buckle part 22 is buckled and connected with the female buckle part 21 through the cage-shaped buckle 221. After connection, the bottom of the female buckle part 21 is fitted with the upper end of the limit clamping ring 222 of the male buckle part 22. The male buckle part 22 is made of an elastic plastic material, and there are several uniformly distributed small strip-shaped gaps on the cage-shaped buckle 221. The cage shape design reduces the extrusion force and deformation force suffered by the connecting piece 2 during use, enhances the performance of the connecting piece 2 and extends its service life.

[0025] Such as Figures 5 to 7The bottom of the pallet body 1 is provided with a pallet connection port 11, and the support leg 3 is provided with a support leg connection port 31. When the connector 2 connects the pallet body 1 and the support leg 3, the female buckle component 21 is partially connected to the pallet connection port 11, and the male buckle component 22 is partially connected to the support leg connection port 31. Among them, a first snap-in groove 111 and a second snap-in groove 112 are provided in the pallet connection port 11, and a first snap-in joint 211 and a second snap-in joint 212 are provided on the outside of the female buckle component 21. The first snap-in groove 111 is provided above the second snap-in groove 112, and accordingly, the first snap-in joint 211 is provided at the top of the female buckle component 21, and the second snap-in joint 212 is provided at the middle section of the female buckle component 21. A third snap-in groove 312 and a fourth snap-in groove 313 are provided in the support leg connection port 31, and a third snap-in joint 223 and a fourth snap-in joint 224 are provided on the outside of the cage-shaped connector 22. The fourth engaging groove 313 is located at the bottom of the leg connection opening 31, and the third engaging groove 312 is located above the fourth engaging groove 313. Accordingly, the fourth engaging joint 224 is located at the bottom of the male buckle component 22, and the third engaging joint 223 is located in the middle section of the cage-shaped connector 22. The engaging joint is a circular protrusion, and the engaging groove is a circular groove that mates with the engaging joint. During connection, each engaging joint engages with its corresponding engaging groove. The inner diameter of the engaging groove is slightly larger than the inner diameter of the engaging joint, allowing the connector 2 to securely connect the tray body 1 and the leg 3 while reducing wear.

[0026] A limiting groove 311 is further provided at the top of the support leg connection port 31 , and the limiting groove is used to cooperate with the limiting clamp ring 222 to further limit the position of the connecting piece.

[0027] During actual production of the present invention, the female buckle component 21 and the male buckle component 22 are first injection molded separately. The female buckle component 21 is then integrally molded with the pallet body 1, and the male buckle component 22 is integrally molded with the support leg 3. Specifically, the molded female buckle component 21 is placed in the mold of the pallet body 1, and then blow molding is used to complete the production setup of the pallet body 1, simultaneously completing the integral connection between the female buckle component 21 and the pallet body 1. At this point, the various snap joints provided on the female buckle component 21 and the various snap grooves provided in the pallet connection port 11 ensure the stability of the integral connection structure. Similarly, the male buckle component 22 is placed in the mold of the support leg 3, and blow molding is used to complete the integral connection between the male buckle component 22 and the support leg. After the female buckle 21 and male buckle 22 are integrally connected to the tray body 1 and the support leg 3, respectively, the cage-shaped buckle 221 of the male buckle 22 is snapped into the interior of the female buckle 21, and the two are fixedly connected by snapping. At this time, the bottom of the female buckle 21 is in contact with the limiting snap ring 222 of the male buckle 22. The snap connection of the connector 2 is completed, and the tray body 1 and the support leg 3 are also integrally connected.

[0028] In the present utility model, there are three supporting feet 3 in total. Each supporting foot 3 has three supporting foot connection ports 31, and the distances between the supporting foot connection ports on each supporting foot 3 are equal. Correspondingly, there are 9 tray connection ports 11 and connecting members 2 in total. During installation, the supporting feet 3, the nine connecting members 2 and the tray body 1 are connected from bottom to top. When connecting, the midpoints of the supporting foot connection ports 31, the connecting members 2 and the tray connection ports 11 form a vertical perpendicular line. After each clamping head on the connecting member 2 is connected to each clamping groove in the connection port, the supporting feet 3, the connecting members 2 and the tray body 1 are combined into a complete H-shaped tray. The connecting member 2 of the tray adopts a cage-shaped buckle structure, which has certain elasticity and can share the shear stress from the tray body 1 and the supporting feet 3, and extends the service life of the tray body 1 and the supporting feet 3, which are relatively higher in cost compared to the connecting member 2.

[0029] The above content describes the structure, main embodiments and advantages of the present utility model. It should be noted that the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model. The protection scope required by the present utility model is defined by the appended claims and their equivalents.
