Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard packaging box technology, specifically to a corrugated cardboard packaging box that facilitates ventilation and heat dissipation. Background Technology

[0002] Corrugated cardboard boxes are packaging containers made of corrugated cardboard. With their excellent cushioning performance, lightweight characteristics, and recyclability, they are widely used for the transportation and storage of various items such as food, electronics, and daily necessities.

[0003] In existing corrugated cardboard packaging boxes, to ensure the protection and sealing of the contents, the box body is usually designed to be closed or have only a few small holes. This structure can easily lead to poor air circulation inside the box and heat accumulation. For fresh fruits and vegetables and other items that require ventilation and heat dissipation, the high temperature and humidity inside the box can easily cause mold or rot. Therefore, a corrugated cardboard packaging box that facilitates ventilation and heat dissipation is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a corrugated cardboard packaging box that facilitates ventilation and heat dissipation is provided. This technical solution addresses the issue mentioned in the background art that in the use of existing corrugated cardboard packaging boxes, in order to ensure the protection and sealing of the internal items and the dustproof effect, the box body is usually designed with a closed structure or only a few small holes. This structure easily leads to poor air circulation inside the box, and heat is easily accumulated. For fresh fruits and vegetables and other items that need to be ventilated and dissipated, the high temperature and humidity inside the box can easily cause mold or spoilage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A corrugated cardboard packaging box for easy ventilation and heat dissipation includes a box body. Several evenly distributed first ventilation holes are provided through both the left and right ends of the box body. A fixing frame is fixedly connected to both the left and right ends of the box body. A sliding groove is provided at the top and bottom inner sides of the fixing frame. A baffle is slidably connected inside the sliding groove. A second ventilation hole, matching the number and size of the first ventilation holes, is provided through the right end of the baffle. Four evenly distributed fixing blocks are fixedly connected to the side of the baffle away from the box body. A T-shaped groove is provided inside the fixing block. A T-shaped block is slidably connected inside the T-shaped groove. Two sets of slots are provided at the top and bottom inner sides of the fixing frame. Each set of slots contains two slots. A locking block is fixedly connected inside the slot. An elastic hook is fixedly connected to the end of the T-shaped block near the slot.

[0007] Preferably, the second ventilation hole and the first ventilation hole are staggered.

[0008] Preferably, the elastic hook is inserted into the inside of the slot, and the elastic hook is hooked to the card block.

[0009] Preferably, a pusher block is fixedly connected to the end of the T-shaped block away from the baffle.

[0010] Preferably, the end of the pusher block away from the T-shaped block has multiple evenly distributed anti-slip grooves.

[0011] Preferably, the distance between the two slots is equal to the distance between the adjacent first ventilation hole and second ventilation hole.

[0012] The advantages of this utility model compared with the prior art are:

[0013] This solution proposes a corrugated cardboard packaging box that facilitates ventilation and heat dissipation. Through the sliding of the baffle and the locking structure of the slot, a stable switching between two states—fully open and fully closed—is achieved. In the closed state, the baffle completely covers the first ventilation hole, effectively preventing dust and moisture from entering. In the open state, the first and second ventilation holes are completely aligned, allowing external air to enter the packaging box and hot air inside the box to dissipate through the ventilation holes. This meets the usage needs of corrugated cardboard packaging boxes in different scenarios. Furthermore, the design of the push block and elastic hook allows operators to switch between the two states without the need for tools, making it convenient to use. Attached Figure Description

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figures 1-8 As shown, a corrugated cardboard packaging box that facilitates ventilation and heat dissipation includes a packaging box body 1. Several evenly distributed first ventilation holes 101 are opened through both the left and right ends of the packaging box body 1. Fixed frames 2 are fixedly connected to both the left and right ends of the packaging box body 1. Sliding grooves 3 are opened at the top and bottom inner sides of the fixed frames 2. Baffles 4 are slidably connected inside the sliding grooves 3. Second ventilation holes 401 with the same number and size as the first ventilation holes 101 are opened through the right end of the baffles 4. Four evenly distributed fixed blocks 5 are fixedly connected to the side of the baffles 4 away from the packaging box body 1. T-shaped grooves 8 are opened inside the fixed blocks 5. T-shaped blocks 9 are slidably connected inside the T-shaped grooves 8. Two sets of slots 6 are opened at the top and bottom inner sides of the fixed frames 2. Each set of slots 6 has two slots. A locking block 7 is fixedly connected inside the slot 6. An elastic hook 10 is fixedly connected to the end of the T-shaped block 9 near the slot 6.

[0026] Furthermore, the second ventilation hole 401 is staggered with the first ventilation hole 101.

[0027] Furthermore, the packaging box body 1 serves as the main packaging component, with its interior used for placing items. The fixing frame 2 is fixed to the left and right ends of the packaging box body 1 by adhesive bonding and corresponds to the area of ​​the first ventilation hole 101. The sliding groove 3 provides a guide track for the sliding of the baffle 4, ensuring that the baffle 4 moves smoothly along a straight line and accurately achieves state switching. The baffle 4 is slidably connected in the sliding groove 3, and the relative position of the second ventilation hole 401 and the first ventilation hole 101 is changed by sliding. When the second ventilation hole 401 and the first ventilation hole 101 are directly opposite each other, the first ventilation hole 101 is fully open, and at this time, external air can enter the interior of the packaging box body 1, and the hot air inside the packaging box body 1 can also be dissipated to the outside through the ventilation hole. When the second ventilation hole 401 and the first ventilation hole 101 are misaligned, the first ventilation hole 101 is fully closed, and at this time, the packaging box body 1 is in a sealed state.

[0028] Furthermore, the elastic hook 10 is inserted into the inside of the slot 6, and the elastic hook 10 is hooked to the card block 7.

[0029] Furthermore, the distance between the two slots 6 is equal to the distance between the adjacent first ventilation hole 101 and second ventilation hole 401.

[0030] Furthermore, a push block 11 is fixedly connected to the end of the T-shaped block 9 away from the baffle 4, and the end of the push block 11 away from the T-shaped block 9 has multiple evenly distributed anti-slip grooves 12.

[0031] Furthermore, the slot 6 is provided in four sets, with two slots in each set. The two slots 6 correspond to the positions of the baffle 4 when the first ventilation hole 101 is in the open and closed states, respectively. When the baffle 4 slides to the open and closed states of the first ventilation hole 101, the elastic hook 10 is inserted into the inside of the slot 6 and hooked to the block 7 by pushing the push block 11, which can fix the current position of the baffle 4. The anti-slip groove 12 is a strip-shaped groove, which can increase the friction between the finger and the push block 11 and prevent slippage when pushing the push block 11.

[0032] Working principle: During use, the ventilation state is switched according to the storage and transportation needs of the items. When transporting fresh fruits and vegetables or other items that require ventilation, the push block 11 is pushed to disengage the elastic hook 10 from the locking block 7 in the locking slot 6 and slide the baffle 4 along the sliding groove 3 until the second ventilation hole 401 is completely aligned with the first ventilation hole 101 of the packaging box body 1. Then, the push block 11 is pushed to make the elastic hook 10 engage in the corresponding locking slot 6 and hook with the locking block 7. At this time, all ventilation holes are open, and the air inside and outside the box can circulate and dissipate heat through the aligned ventilation holes. When transporting electronic components or other items that require dust and moisture protection, or when transporting in rainy weather, the push block 11 can be pushed to unlock the baffle 4 and slide the baffle 4 along the sliding groove 3 until the solid part of the baffle 4 completely covers the first ventilation hole 101. Then, the push block 11 is pushed to make the elastic hook 10 engage in the corresponding locking slot 6 and hook with the locking block 7. At this time, all ventilation holes are closed, which can effectively prevent external dust and moisture from entering the box.
