[0039] Example 1

[0040] This embodiment provides a pallet that improves product packaging efficiency by providing a guiding slope on a limiting member for fixing the box to guide the assembly of the box and the pallet. In one possible embodiment, the pallet is used to package a 12kV vacuum circuit breaker.

[0041] Specifically, if Figures 1-4 As shown, the pallet includes a tray body 100. A plurality of stoppers 110 are provided along the circumference of the tray body 100. The stoppers 110 define a space for securing the product 10 to be packaged. The outer walls of the stoppers 110 are provided with inclined guide surfaces 1131, which are inclined toward the space and serve to guide the assembly of the box 200 and the stoppers 110.

[0042] The specific steps of assembling the box 200 on the pallet are:

[0043] First, move the box 200 to the top of the tray body 100 so that the opening of the box 200 faces the plurality of stoppers 110 ;

[0044] Then, the box body 200 is moved downward. During the process of moving the box body 200, the outer edge of the opening of the box body 200 will contact multiple guide slopes 1131 at the same time. As the box body 200 moves further downward, the box body 200 will slide on the guide slopes 1131 along the inclined direction of the guide slopes 1131 until it is completely mounted outside the multiple limit members 110.

[0045] The pallet provided in this embodiment guides the assembly of the box body 200 by providing a guiding slope 1131 on the limiting member 110, thereby effectively reducing the difficulty of assembling the box body 200. This allows the box-housing robot to more easily put the box body 200 on the pallet during automated packaging, thereby improving the qualified rate of the box-housing assembly and eliminating the need for manual straightening of the box body 200. This improves the packaging efficiency while reducing the labor intensity of the workers.

[0046] Optionally, in order to improve the smoothness of the movement of the box body 200 on the guide slope 1131 and reduce the difficulty of assembling the box body 200 and the tray, the guide slope 1131 can be set to be smooth.

[0047] Optionally, the material of the limiting member 110 may be plastic, which has a low cost and a smooth surface.

[0048] Optionally, the material of the pallet body 100 may be wood.

[0049] Optionally, the limiting member 110 may be fixed to the tray body 100 by bolt connection. The bolt connection structure is simple, easy to install, and has high connection strength.

[0050] Further, see Figure 1 The box 200 includes a cylindrical body 210 and a lid 220. One end of the cylindrical body 210 is sleeved over the plurality of retaining members 110, and the other end of the cylindrical body 210 is capped with the lid 220. When using this tray to package products 10, the cylindrical body 210 is first sleeved over the plurality of retaining members 110 of the tray body 100, and then the lid 220 is placed on the cylindrical body 210. The box 200 includes the cylindrical body 210 and the lid 220. Opening the lid 220 allows for easy access to the products 10, making unpacking more flexible and meeting various user needs.

[0051] Further, see Figure 2-Figure 4 In this embodiment, a limiting member 110 is provided at both ends of each side of the tray body 100. The two adjacent limiting members 110 provided on the adjacent sides form an integrated structure through a connecting member 120. By providing a limiting member 110 at both ends of each side of the tray body 100, each corner of the tray body 100 has two adjacent limiting members 110. On the one hand, each corner of the box body 200 is supported by two limiting members 110, which can not only ensure the fixing effect of the box body 200, but also improve the strength of the corners of the box body 200; on the other hand, the corners of the product 10 can be fixed, and the limiting effect is better. In addition, the two adjacent limiting members 110 are connected into an integrated structure by the connecting member 120, which not only facilitates the removal of the two limiting members 110 when installing them on the tray body 100, but also facilitates the positioning of the two limiting members 110, thereby reducing the difficulty of installing the limiting members 110 on the tray body 100.

[0052] Further, see Figure 3 and Figure 4The limiting member 110 includes a connecting portion 111, a fixing portion 112, and a guide portion 113, which are sequentially connected. The connecting portion 111 is fixed to the tray body 100 and is used to abut against the product 10. The connecting portion 111 and the fixing portion 112 are arranged perpendicularly. The outer wall of the fixing portion 112 abuts against the inner wall of the box body 200. The fixing portion 112 and the guide portion 113 are arranged at an angle. The guide portion 113 forms a guide slope 1131 by being arranged at an angle with the fixing portion 112. The connecting member 120 is a connecting strip. One end of the connecting strip is bent and connected to the fixing portion 112 of one limiting member 110, and the other end of the connecting strip is bent and connected to the fixing portion 112 of another limiting member 110. The limiting member 110 has a simple structure and a good limiting effect.

[0053] Optionally, continue with Figure 4 The connecting portion 111 is connected to the fixing portion 112 via a first arcuate transition section 114, and the fixing portion 112 is connected to the guide portion 113 via a second arcuate transition section 115. This arrangement allows for a smoother connection between the connecting portion 111 and the fixing portion 112, and a smoother connection between the fixing portion 112 and the guide portion 113, thereby reducing friction between the stopper 110 and the housing 200, and thereby easing the difficulty of assembling the housing 200 and the stopper 110.

[0054] Optionally, in this embodiment, the connecting portion 111, the fixing portion 112, and the guiding portion 113 are integrally formed. This facilitates processing. For example, if the stopper 110 is made of plastic, it can be integrally formed through injection molding. If the stopper 110 is made of metal, it can be formed by bending a metal sheet.

[0055] Alternatively, as Figure 5 As shown, the included angle a between the fixing portion 112 and the guide portion 113 is 135°-160°. In this way, the guiding effect of the guide portion 113 is better. For example, the included angle between the fixing portion 112 and the guide portion 113 can be 135°, 140°, 145°, 150°, 155°, or 160°, etc., and can be set according to actual needs. This application does not impose any specific limitations.

[0056] Optionally, a connection hole may be provided on the connection portion 111 , so that a screw passes through the connection hole and is connected to the tray body 100 , thereby fixing the limiting member 110 on the tray body 100 .

[0057] Further, see Figure 1-Figure 3The tray body 100 is detachably connected to a product fixing member 130, one end of which is engaged with the engaging portion 11 of the product 10. The product fixing member 130 cooperates with the stopper 110 to secure the product 10 to the tray body 100, preventing the product 10 from shaking within the box 200 during transportation and improving the reliability of the product 10 packaging.

[0058] Optionally, continue with Figure 2 In this embodiment, the product fixing member 130 is L-shaped, with a snap-in hole 131 at one end of the L-shaped member. The snap-in hole 131 engages with the snap-in portion 11. The snap-in hole 131 connects the product fixing member 130 to the snap-in portion 11 of the product 10, resulting in a simple structure and easy installation.

[0059] Optionally, the other end of the product fixing member 130 can be detachably connected to the tray body 100 by means of a bolt connection. Specifically, when packaging the product 10, the product 10 is first fixed to a specific position on the tray body 100 using the stopper 110, and then one end of the product fixing member 130 is clamped to the clamping portion 11 of the product 10. Finally, a screw is installed between the other end of the product fixing member 130 and the tray body 100 to secure them.

[0060] Optionally, product fixing members 130 are provided on at least two opposite sides of the tray body 100 , and each product fixing member 130 is located between a plurality of limiting members 110 on the same side.

[0061] In this embodiment, four product fixing members 130 are provided. The four product fixing members 130 are respectively arranged on opposite sides of the tray body 100, with two product fixing members 130 on each side. Of course, in other embodiments, the number and arrangement of product fixing members 130 can also be other, and can be adapted to the clamping portion 11 on the product 10. This application does not specifically limit this.

[0062] Furthermore, the product 10 is wrapped in a packaging bag. The packaging bag can, on the one hand, wrap the product 10 and its parts together; on the other hand, it can provide a certain degree of protection for the product 10, preventing it from being scratched or dirty during transportation.
