[0007] Preferably, the second side plate includes side plate A and side plate B, and a top plate is fixedly installed on one side of side plate A.
[0008] Preferably, a first outer protective plate is fixedly installed on one side of the top plate, and a second outer protective plate is installed on both sides of the first outer protective plate.
[0009] Preferably, a second transparent window is provided on the front of the second outer protective plate, and a connecting plate is fixedly installed on the outer side of the second outer protective plate.
[0010] Preferably, one side of the connecting plate is fixedly equipped with a Velcro A side and a Velcro B side.
[0011] Preferably, the first side plate, the second side plate, the sealing plate, the first outer protective plate, the second outer protective plate, and the connecting plate are all provided with bending portions at their joints.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model, through the structural design of a first side plate, a second side plate, a sealing plate, and a slot, and through the cooperation between the structures, achieves the function of increasing packaging convenience. Thus, the connection between the side plates can be ensured by the structure of the cardboard box itself, and the sealing plate is embedded in the slot during the packaging process to complete the connection of the side plates as a whole. This avoids the need to rely on external components to increase the protection of the packaging box during subsequent packaging, while reducing the steps and time consumption in the packaging process, and solving the problem of inconvenience in use.
[0014] 2. This utility model achieves the function of increasing the overall protection of the packaging box by cooperating with the first outer protective plate and the second outer protective plate. Thus, the double-layer structure can be used to resist external impact, dust and moisture, and provide reliable protection for the contents. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses a packaging box structure, including a base plate 1, with a first side plate 2 and a second side plate 3 fixedly installed around the base plate 1. Sealing plates 4 are fixedly installed on both sides of the top of the first side plate 2. The second side plate 3 has slots 5 on both sides, which are adapted to the sealing plates 4. A first transparent window 6 is provided on the front of the first side plate 2.
[0024] Reference Figure 1 , Figure 2 , Figure 4 Through the structural design of the first side panel 2, the second side panel 3, the sealing plate 4, and the slot 5, and through the cooperation between the structures, the function of increasing packaging convenience is achieved. Thus, the connection between the side panels can be ensured by the structure of the cardboard box itself. The sealing plate 4 is embedded in the slot 5 during the packaging process to complete the connection of the side panels as a whole, avoiding the need to rely on external components to increase the protection of the packaging box during subsequent packaging, while reducing the steps and time consumption in the packaging process.
[0025] The second side plate 3 includes side plate A301 and side plate B302, and a top plate 7 is fixedly installed on one side of side plate A301.
[0026] Reference Figure 1 and Figure 2 The top plate 7 facilitates the closure of the top of the packaging box, thereby achieving the purpose of fully protecting the items inside the packaging box.
[0027] A first outer protective plate 8 is fixedly installed on one side of the top plate 7, and a second outer protective plate 9 is installed on both sides of the first outer protective plate 8.
[0028] Reference Figure 1 , Figure 2 , Figure 3 The first outer protective plate 8 and the second outer protective plate 9 work together to increase the overall protection of the packaging box. The double-layer structure can protect against external impacts, dust and moisture, and provide reliable protection for the contents.
[0029] The front of the second outer protective plate 9 is provided with a second transparent window 10, and the outer side of the second outer protective plate 9 is fixedly installed with a connecting plate 11.
[0030] Reference Figure 1 , Figure 2 , Figure 3 The second transparent window 10 facilitates the visualization function in conjunction with the first transparent window 6, allowing consumers to observe the contents without opening the packaging, thus enhancing the product display effect. The connecting plate 11 provides installation space for the Velcro A side 12 and Velcro B side 13.
[0031] The connecting plate 11 has Velcro A side 12 and Velcro B side 13 fixedly installed on one side.
[0032] Reference Figure 1 and Figure 2 The outer protective panel can be easily fixed by using the adhesive force of the hook and loop fasteners A side 12 and hook and loop fasteners B side 13, which further improves the overall ease of use of the packaging box, makes it convenient to retrieve items later, and is easy to reuse.
[0033] The first side plate 2, the second side plate 3, the sealing plate 4, the first outer protective plate 8, the second outer protective plate 9, and the connecting plate 11 are all provided with bending parts 14 at their joints.
[0034] Reference Figure 2 The bending section 14 facilitates the subsequent folding and shaping of the packaging box, allowing it to be folded into a flat surface during transportation and storage, saving space; at the same time, it ensures that the structure is stable after folding and is not easily deformed.
[0035] Working principle: When using this device, the first side plate 2 and the second side plate 3 are folded. During this process, the sealing plate 4 is inserted into the slot 5 to complete the connection between the first side plate 2 and the second side plate 3. The top opening of the first side plate 2 and the second side plate 3 is closed by the top plate 7. The sides of the box are wrapped by folding the first outer protective plate 8 and the second outer protective plate 9. Finally, the outer protective plate is fixed by attaching the Velcro A side 12 and the Velcro B side 13 on the connecting plate 11, thus completing the assembly of the entire packaging box.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
