Description

Technical Field

[0001] This utility model belongs to the technical field of wooden packaging boxes, specifically a wooden packaging box that is resistant to deformation. Background Technology

[0002] In the packaging industry, wooden crates are widely used in the transportation and storage of various products due to their good strength, processability and environmental friendliness. They are especially suitable for goods with heavy weight and high requirements for packaging structure stability. With the rapid development of the logistics industry and the increasingly complex product transportation environment, higher requirements have been placed on the performance of wooden crates. Among them, the ability to resist deformation has become a key factor affecting the quality of the crate and the safety of the goods.

[0003] Most common wooden packaging boxes currently use a simple frame structure, consisting of side panels, bottom panels, and top panels connected by nails or mortise and tenon joints. The side panels are generally made of a single layer of wood, while the bottom panels are made of wood of different thicknesses depending on the load-bearing requirements. In terms of connection methods, nailing is simple to operate, but the connection strength is limited; mortise and tenon joints can provide a certain degree of connection stability, but they require high processing precision and are still prone to loosening when subjected to large external impacts.

[0004] However, the frame structure of traditional wooden packaging boxes is prone to deformation or even collapse when faced with large external impacts or long-term heavy loads. The nailing and mortise and tenon joints cannot effectively resist the shear and tensile forces generated by vibration, compression, etc., which will damage the overall structural integrity of the packaging box. For example, during long-distance transportation, the bumps and sudden braking of the vehicle will subject the packaging box to repeated impacts, causing the joints to loosen and the side panels and bottom panels to deform, thus failing to provide reliable protection for the internal goods. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a deformation-resistant wooden packaging box, which solves the problem that the frame structure of traditional wooden packaging boxes is prone to deformation or even collapse when faced with large external impacts or long-term heavy loads, and that nailing and mortise and tenon joints cannot effectively resist shear and tensile forces caused by vibration, compression, etc., resulting in damage to the overall structural integrity of the packaging box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant wooden packaging box, comprising multiple sets of side panels and multiple sets of bottom panels, with side posts snapped together between the side panels, the multiple sets of side panels forming a frame through the side posts, and the bottom panels respectively fixed to both ends of the side panels, the outer sides of the side posts being symmetrically connected with a first locking block and a second locking block, both sides of the side panels having grooves for cooperating with the second locking blocks, the first locking blocks being located inside the side panels and fitting against the inner wall of the side panels, the outer sides of the side panels being symmetrically fixedly installed with multiple sets of first protrusions, the inner sides of the bottom panels being fixedly installed with multiple sets of second protrusions for cooperating with the first protrusions, the second protrusions being able to be inserted into the first protrusions, and the first protrusions and the second protrusions being threadedly connected with second bolts, the outer and inner sides of the side posts having chamfers.

[0007] As a further embodiment of this utility model: a reinforcing plate is fixedly installed on the outer side of the base plate, and a first bolt is threadedly connected between the reinforcing plate and the base plate. The reinforcing plate is composed of two sets of single plates, and the reinforcing plate is fixedly connected to the base plate in an interlaced structure.

[0008] As a further embodiment of this utility model: both the first protrusion and the second protrusion are right-angled triangular structures.

[0009] As a further embodiment of this utility model: multiple sets of slots are provided on the outer side of the base plate, and a slot for use with the side plate and the side column is provided inside the base plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. When the side plate is connected to the side column, the chamfer of the side column avoids stress concentration, enhances the tightness of the connection between the two, and enables them to work together to resist external forces, optimize the frame structure, and help the smooth transmission of force; the connection between the bottom plate and the side plate adopts a right-angled triangular structure protrusion to strengthen the connection strength, while strengthening the plate to disperse the pressure of the bottom plate, reduce stress concentration, slow down material fatigue damage, and comprehensively improve the deformation resistance of the overall structure.

[0012] 2. The chamfered edges of the side columns serve as guides during installation, making it easier to identify the direction and ensuring a smoother installation process. The slots in the base plate reduce weight while maintaining strength and rigidity, lowering the risk of deformation due to excessive weight. At the same time, the slots provide precise positioning for component installation, enhancing the overall structural integrity and optimizing the entire installation process.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution for a deformation-resistant wooden packaging box:

[0020] The device includes multiple sets of side plates 1 and multiple sets of bottom plates 2. Side columns 3 are snap-fitted between the side plates 1. The multiple sets of side plates 1 form a frame through the side columns 3. The bottom plates 2 are fixed to both ends of the side plates 1. The outer side of the side columns 3 is fixedly connected with a first locking block 9 and a second locking block 10 in a symmetrical structure. The side plates 1 have sliding grooves 11 on both sides that cooperate with the second locking blocks 10. The first locking blocks 9 are located inside the side plates 1 and fit against the inner wall of the side plates 1. The outer side of the side plates 1 is fixedly installed with multiple sets of first protrusions 6 in a symmetrical structure. The inner side of the bottom plate 2 is fixedly installed with multiple sets of second protrusions 7 that cooperate with the first protrusions 6. The second protrusions 7 can be inserted into the first protrusions 6. The first protrusions 6 and the second protrusions 7 are threadedly connected with second bolts 8. The outer and inner sides of the side columns 3 are chamfered.

[0021] Specifically, first, pick up the side post 3 and confirm the positions of the first locking block 9 and the second locking block 10 on its outer side. Since both the outer and inner sides of the side post 3 have chamfers, it is easier to identify the direction during assembly. Then, lay the side plate 1 flat with the sliding groove 11 facing upwards. Align the second locking block 10 on the side post 3 with the sliding groove 11 on the side plate 1. At this time, the chamfer on the outer side of the side post 3 acts as a guide, guiding the second locking block 10 to slide smoothly into the sliding groove 11. As the second locking block 10 slides, the first locking block 9 will also gradually enter the interior of the side plate 1 and fit against the inner wall of the side plate 1. Following the above method, assemble the multiple The side panels 1 are connected sequentially by the side posts 3 to form a frame. The assembled frame is then placed stably, and the second protrusion 7 on the inner side of the base plate 2 is aligned with the first protrusion 6 on the outer side of the side panel 1. The chamfers on the inner and outer sides of the side posts 3 make the edges of the entire frame more regular, facilitating accurate alignment of the base plate 2. Next, the second protrusion 7 is inserted into the first protrusion 6, and then the second bolt 8 is used to thread the first protrusion 6 and the second protrusion 7 together, firmly fixing the base plate 2 to both ends of the side panel 1. The chamfers on the outer sides of the side posts 3 make the insertion process smoother and avoid the generation of localized stress. The inner chamfer prevents stress concentration points caused by the inner edge of the side post 3 pressing against other components during installation. The outer chamfer makes the snap-fit ​​connection between the side post 3 and the side plate 1 tighter. During insertion, the guiding effect of the chamfer ensures that the second locking block 10 can accurately enter the slide groove 11. After installation, the fit between the side post 3 and the side plate 1 is tighter, reducing local deformation caused by loose connections. This tight connection allows the side plate 1 and the side post 3 to work together better to resist external loads, enhancing the overall frame's resistance to deformation. The chamfer optimizes the structural geometry of the frame, making the force transmission between various components smoother. When the base plate 2 is subjected to vertical pressure, the force can be transmitted to the side post 3 through the connection of the first protrusion 6, the second protrusion 7, and the second bolt 8. The presence of the chamfer makes the force transmission more uniform and reduces local deformation caused by poor force transmission. During installation, the chamfer of the side post 3 can avoid sharp collisions and friction with other components, reducing damage to the material surface. Damage to the material surface may reduce the strength and toughness of the material, thereby increasing the risk of deformation.

[0022] A reinforcing plate 4 is fixedly installed on the outer side of the base plate 2. The reinforcing plate 4 is threadedly connected to the base plate 2 by a first bolt 13. The reinforcing plate 4 is composed of two sets of single plates, and the reinforcing plate 4 is fixedly connected to the base plate 2 in an interlaced structure. The first protrusion 6 and the second protrusion 7 are both right-angled triangular structures. Multiple sets of slots 5 are opened on the outer side of the base plate 2. The base plate 2 is provided with a slot 12 for use with the side plate 1 and the side column 3.

[0023] Specifically, the reinforcing plate 4 is threadedly connected to the base plate 2 by the first bolt 13, which effectively increases the overall strength of the base plate 2. The reinforcing plate 4, composed of two sets of single plates, is fixed to the base plate 2 in an interlaced structure, providing support to the base plate 2 in different directions, dispersing the pressure on the base plate 2, reducing the possibility of deformation due to excessive local stress, and making the base plate 2 more stable when subjected to heavy objects or external impacts. The interlaced structure of the reinforcing plate 4 can improve the stress state of the base plate 2, reduce stress concentration in the base plate 2 during repeated stress processes, and when the base plate 2 is subjected to periodic external forces, the reinforcing plate 4 can share some of the stress, slow down the fatigue damage of the base plate 2 material, extend the service life of the base plate 2, and improve the overall structural strength. The fatigue resistance makes it less prone to deformation and damage due to fatigue. The right-angled triangular structure has good stability and mechanical properties. The first protrusion 6 and the second protrusion 7 adopt this structure, which can provide a more reliable connection during insertion and mating. When the hypotenuse of the triangle contacts other parts, it can provide a larger contact area and friction, making the connection between the first protrusion 6 and the second protrusion 7 tighter and less prone to relative slippage or loosening. This enhances the connection strength between the base plate 2 and the side plate 1 and improves the deformation resistance of the entire structure. Multiple sets of slots 5 are opened on the outer side of the base plate 2, which can effectively reduce the weight of the base plate 2 without significantly affecting its strength and rigidity, making the entire structure lighter.

[0024] The working principle of this utility model is as follows:

[0025] First, the connection between side panel 1 and side column 3 forms the basic frame structure. The first locking block 9 and the second locking block 10 on the outer side of side column 3 cooperate with the sliding groove 11 of side panel 1. The chamfers on the outer and inner sides of side column 3 play a key role in the installation. The outer chamfer guides the second locking block 10 to slide smoothly into the sliding groove 11 of side panel 1, making it easy to identify the installation direction, ensuring a smooth insertion process, and avoiding the generation of local stress. The inner chamfer prevents the inner edge of side column 3 from being squeezed by other components, forming stress concentration points. After installation, side column 3 and side panel 1 fit tightly together, reducing local deformation caused by loose connections, allowing the two to better cooperate in resisting external loads, optimizing the geometry of the frame structure, facilitating smoother force transmission between components, and enhancing the overall resistance to deformation.

[0026] Secondly, the connection between the base plate 2 and the frame further stabilizes the whole structure. The second protrusion 7 on the inner side of the base plate 2 is inserted into the first protrusion 6 on the outer side of the side plate 1 and is connected by the second bolt 8. The first protrusion 6 and the second protrusion 7 adopt a right-angled triangular structure. The hypotenuse provides a larger contact area and friction, tightly connecting the base plate 2 and the side plate 1, enhancing the connection strength and improving the structural resistance to deformation. At the same time, a reinforcing plate 4 is fixed on the outer side of the base plate 2. It consists of two sets of single plates that are staggered and connected to the base plate 2 by the first bolt 13. This structure provides support for the base plate 2 in different directions, disperses pressure, reduces deformation caused by excessive local stress, improves the stress state of the base plate 2, reduces stress concentration during repeated stress, slows down material fatigue damage, extends the service life of the base plate 2, and improves the overall fatigue resistance.

[0027] Finally, multiple slots 5 are opened on the outer side of the base plate 2. While ensuring that the strength and rigidity are not significantly affected, the weight of the base plate 2 is reduced, making the entire structure lighter. In some scenarios where weight is a requirement, the risk of structural deformation due to excessive weight is reduced. The slots 12 inside the base plate 2 provide precise positioning and matching space for the installation of the side plate 1 and the side column 3, ensuring accurate installation of each component, enhancing the overall structure, helping to evenly transmit force among the components, and improving the overall deformation resistance of the structure.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
