Technical Field
[0001] This utility model relates to the field of rodent prevention technology for fruit packaging boxes, and in particular to a rodent-proof protective device for fruit packaging boxes. Background Technology
[0002] The fruit packaging box anti-rodent protection device is a functional device designed to prevent rodents from gnawing on the packaging box and the fruit inside during fruit storage and transportation. Its core principle is to build a protective barrier through various repelling methods to prevent rats from damaging the packaging box and the fruit.
[0003] Common packaging boxes are usually made of corrugated cardboard cut and folded in one piece. The box body includes four adjacent side walls, a lid at the top of the side walls, and a bottom at the bottom of the side walls. When this type of packaging box is stacked, the side walls will expand and deform outward under the pressure of the weight above, which will compress the products inside the packaging box. For example, some fruits with high water content, such as tangerines and oranges, will be compressed during long-distance transportation. If the packaging box deforms under the weight and compresses the fruit inside, the fruit will crack and the juice will seep out. The paper packaging box absorbs the juice and softens. Under continuous weight, it is more likely to deform. This will also cause other packaging boxes to become damp and even cause the fruit inside to spoil.
[0004] To address the aforementioned issues, existing rodent-proof protection devices for fruit packaging boxes typically use steel plates or similar structures to protect the boxes from rodent damage. While this method can prevent rodents from damaging the boxes, the steel plates themselves are heavy, making them inconvenient to use, and the protection effect is rather limited, resulting in insufficient practicality.
[0005] Therefore, a rodent-proof protective device for fruit packaging boxes is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a rodent-proof protection device for fruit packaging boxes, which can solve the problems of existing rodent-proof protection devices for fruit packaging boxes, which usually use steel plates or other structures to protect the packaging boxes to prevent rodents from biting them. Although this method can prevent rodents from biting and damaging the packaging boxes, the steel plates themselves are heavy, which is inconvenient to use, and the protection effect on the packaging boxes is relatively simple and lacks practicality.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a rodent-proof protective device for fruit packaging boxes, comprising a packaging box body, rodent-proof mechanisms threadedly connected to both sides of the packaging box body, and auxiliary mechanisms fixedly connected to the surface of the packaging box body;
[0008] The rodent-proof mechanism includes a wire mesh, ventilation holes, a DEET coating, a rubber buffer layer, a plastic box, and reinforcing ribs. The wire mesh is threaded to both sides of the main body of the packaging box. The ventilation holes are located on the inner walls of both sides of the main body of the packaging box. The DEET coating is applied to the rear surface of the main body of the packaging box. The rubber buffer layer is fixedly connected to the inner wall of the wire mesh. The plastic box is threaded to both sides of the main body of the packaging box. The reinforcing ribs are fixedly connected to the four corners of the main body of the packaging box. The plastic box is fixedly connected directly below the ventilation holes.
[0009] Preferably, the auxiliary mechanism includes a honeycomb panel and an observation window, the honeycomb panel being fixedly connected to the surface of the main body of the packaging box, and the observation window being opened on the front side of the main body of the packaging box.
[0010] Preferably, the inner wall of the wire mesh and the main body of the packaging box is provided with threaded holes, and the inner wall of the threaded holes is threaded with a threaded rod.
[0011] Preferably, the top of the plastic box is snapped with a lid, and the lid and the inner wall of the plastic box are provided with mesh.
[0012] Preferably, the surface of the honeycomb panel is fixedly connected with raised strips, and the bottom of the main body of the packaging box is fixedly connected with a polycarbonate protective railing.
[0013] Preferably, a lid is snapped onto the top of the main body of the packaging box, and handles are fixedly connected to both sides of the main body of the packaging box.

[0015] Preferably, the polycarbonate guardrail is fixedly connected to the bottom of the honeycomb panel, and the inner wall of the plastic box and the main body of the packaging box is threaded with a limit rod.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This application sets up a rodent-proof mechanism by combining wire mesh with DEET coating. This not only prevents rats from gnawing through physical barriers but also repels rats through scent. It eliminates the need for heavy steel plates, reducing the weight of the device and making it more convenient to use.
[0018] 2. The auxiliary mechanism of this application not only enhances the structural strength of the packaging box and improves its pressure resistance, but also allows for easy viewing of the fruit inside the box through the observation window.

[0030] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the auxiliary mechanism 2 includes a honeycomb panel 21 and an observation window 25. The honeycomb panel 21 is fixedly connected to the surface of the packaging box body 3, and the observation window 25 is opened on the front side of the packaging box body 3.
[0031] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, the inner walls of the wire mesh 11 and the main body of the packaging box 3 are provided with threaded holes 15, and the inner walls of the threaded holes 15 are threaded with threaded rods 12.
[0032] Specifically, such as Figure 4 , Figure 5 As shown, a lid 18 is snapped onto the top of the plastic box 17, and mesh openings are provided on the lid 18 and the inner wall of the plastic box 17.
[0033] In this embodiment: the honeycomb panel 21 can improve the protective effect of the main body 3 of the packaging box, making it more difficult for mice to climb. The observation window 25 can be set to facilitate the viewing of the fruit inside the box. The threaded hole 15 can be opened to install the threaded rod 12. The threaded rod 12 can be set to thread the wire mesh 11 to both sides of the main body 3 of the packaging box. The box cover 18 can limit the plastic box 17. The mesh can be opened to allow the natural rodent repellent inside the plastic box 17 to diffuse.
[0034] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, a raised strip 22 is fixedly connected to the surface of the honeycomb panel 21, and a polycarbonate protective railing 24 is fixedly connected to the bottom of the main body 3 of the packaging box.

[0036] In this embodiment: by setting the protruding strip 22, the structural strength of the main body 3 of the packaging box is enhanced, the deformation during stacking is reduced, and the rodents are prevented from using it for leverage when climbing. At the same time, the ropes and debris are prevented from getting tangled and affecting the protective effect. The bottom of the main body 3 of the packaging box is protected by the polycarbonate guardrail 24 to prevent the bottom from being damaged by pressure or rodent bites. The box cover 23 can seal the main body 3 of the packaging box. The handle 26 makes it convenient for users to lift the main body 3 of the packaging box.
[0037] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the ventilation hole 13 is slanted, and a handle is fixedly connected to the top of the cover 23.
[0038] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the polycarbonate guardrail 24 is fixedly connected to the bottom of the honeycomb panel 21, and the inner wall of the plastic box 17 and the main body of the packaging box 3 is threaded with a limit rod.

[0040] Working principle: When using the rodent-proof device on the main body 3 of the fruit packaging box, first place the fruit inside the main body 3 and close the lid 23. Then, the wire mesh 11 in the rodent-proof mechanism 1 is fixed to both sides of the main body 3 of the packaging box via threaded rods 12, forming a physical barrier to prevent rats from directly gnawing on the main body 3 of the packaging box. The DEET coating 14 is applied to the back of the main body 3 of the packaging box, releasing an odor to repel rats. Natural rodent repellents, such as peppermint oil and camphor, can be placed inside the plastic box 17. The odor is slowly released through the mesh holes on the lid 18 and the inner wall of the plastic box 17, which, together with the DEET coating 14, enhances the rodent-repelling effect. Since the ventilation holes 13 are inclined, they can guide the diffusion of the odor while preventing rats from entering. The honeycomb panel 21 and convex strip 22 in auxiliary mechanism 2 enhance the structural strength of the packaging box body 3, reduce deformation during stacking, and prevent rats from using their strength to climb. They also prevent ropes and debris from getting tangled and affecting the protective effect. The polycarbonate guardrail 24 protects the bottom of the packaging box body 3, preventing damage to the bottom due to pressure or rat bites. The observation window 25 allows for easy viewing of the fruit inside the box. The handle 26 facilitates handling. The reinforcing ribs 19 are fixed at the four corners of the packaging box body 3, further enhancing the anti-biting ability of the packaging box body 3. The rubber buffer layer 16 is located on the inner wall of the wire mesh 11, which can absorb the impact force when rats bite, while reducing the direct friction between the wire mesh 11 and the packaging box body 3, extending the service life of the device.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
