Description

Technical Field

[0001] The utility model relates to the technical field of wooden box packaging and transportation, in particular to a fixing clamp and a packaging structure. Background Art

[0002] Stacking boxes upside down for transportation is a common method in logistics transportation.

[0003] In the prior art, a cable tie is usually used to bundle the upper and lower packaging boxes as a whole, so that the upper and lower packaging boxes are fixed as a whole.

[0004] However, shaking is inevitable during transportation. During the shaking process, the cable ties are very likely to rub against the packaging box, causing the cable ties to break. Due to the failure of fixation, the packaging box is more likely to fall over during the next shaking, causing damage to the goods. Utility Model Content

[0005] The embodiments of the present invention provide a fixing fixture and a packaging structure, which are intended to improve the fixing degree of upper and lower packaging boxes.

[0006] In order to achieve the above-mentioned purpose, the embodiments of the present invention adopt the following technical solutions:

[0007] In a first aspect, a fixing fixture is provided for fixing a plurality of stacked boxes, wherein the fixing fixture includes a plurality of sub-fixing fixtures, wherein each sub-fixing fixture includes a positioning structure and a connecting structure pair. The positioning structure includes two connected fixing plates. The positioning structure is configured to be arranged at the contact vertices of the adjacent stacked boxes, and to make the two fixing plates respectively fit with two connecting surfaces. The connecting surfaces are the surfaces where the adjacent stacked boxes are connected. The connecting structure pair includes two connecting structures, and the two connecting structures are respectively connected to the side walls of the two fixing plates. The connecting structure is configured to be connected to the adjacent connecting structures in the other connecting structure pairs.

[0008] The fixing plate of each of the multiple sub-fixing fixtures can cover the two contacting corners of the box respectively. This multi-faceted contact method effectively increases the number of fixing points and the contact area, improves the fit between the sub-fixing fixture and the box, and thus improves the stability of the fixation. When the sub-fixing fixtures are connected to each other, the surface of the connecting structure and the fixing plate are coplanar, and both are tightly attached to the surface of the box, the fit between the entire fixing fixture and the box is significantly increased. This coplanar design ensures that the connecting structure and the fixing plate form a continuous force-bearing area on the surface of the box, avoiding the possibility of loosening or falling off. Since the connecting structure and the fixing plate are coplanar on the surface of the box, the applied fixing force will be evenly distributed on the connecting structure and the fixing plate, and then act on the box. It avoids stress concentration due to excessive force on a certain part, reduces the risk of damage to the box surface, and extends the service life of the box.

[0009] As a possible implementation manner, the fixing plate includes a first fixing plate and a second fixing plate, and the first fixing plate is vertically connected to the second fixing plate.

[0010] As a possible implementation manner, the number of sub-fixtures is the same as the number of common vertices of adjacent stacked boxes.

[0011] As a possible implementation manner, a surface of the connecting structure close to the box body is coplanar with a surface of the connected fixing plate close to the box body.

[0012] As a possible implementation, the size of the fixing plate in a first direction is larger than the size of the connecting structure connected to the fixing plate in the first direction, and the size of the fixing plate in a second direction is larger than the size of the connecting structure connected to the fixing plate in the second direction. The first direction is the stacking direction of the multiple boxes, and the second direction is perpendicular to the first direction.

[0013] As a possible implementation, the connection structure includes a collector, which includes a shell and a telescopic belt arranged in the shell. The shell is provided with an opening for accommodating the passage of the telescopic belt, and a hook is provided at the end of the telescopic belt passing through the opening.

[0014] As a possible implementation manner, the width of the hook is greater than the width of the opening.

[0015] As a possible implementation, a roller, a spiral spring, and a fixed post are further disposed within the housing. The fixed post is connected to the housing and extends through the roller. The spiral spring is wound around the fixed post, with one end of the spiral spring connected to the fixed post and the other end connected to the inner sidewall of the roller. A telescopic belt is wound around the outer sidewall of the roller, with one end of the belt connected to the roller and the other end extending through the opening.

[0016] As a possible implementation manner, the winding direction of the spiral spring is the same as the winding direction of the telescopic belt.

[0017] In the second aspect, a packaging structure is provided, which includes a plurality of stacked boxes and at least one fixing fixture as mentioned in the first aspect and its possible implementation methods, wherein the positioning structures in each sub-fixing fixture in the fixing fixture are respectively arranged at the contact vertices of the adjacent stacked boxes, and the two fixing plates are respectively fitted with the two connecting surfaces, and the connecting structures in each sub-fixing fixture in the fixing fixture are connected to the adjacent connecting structures in the other connecting structures.

[0018] Among them, the beneficial effects of the second aspect can refer to the beneficial effects of the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0039] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0040] During the logistics and transportation process, scattered items are often packaged, meaning that a large number of loose items are packed into a single box. The specifications of the boxes used by the same logistics and transportation company are usually the same. To improve space utilization, stacking the boxes for transportation is also a common practice in logistics and transportation.

[0041] For example, Figure 1 As shown, Figure 1 1 shows a stacked box 1. Box A is stacked on top of box B. In practical applications, such as in logistics and transportation, the box 1 can be a packaging box.

[0042] Currently, packaging boxes (hereinafter also referred to as boxes) stacked up one above the other are usually bundled with straps or tie wraps. For example, Figure 2 shown. Figure 2 The stacked boxes A and B are tied together with multiple cable ties 2, so that the upper and lower boxes 1 are fixed together. However, during transportation, shaking is inevitable, and during shaking, the cable ties 2 are very likely to rub against the packaging boxes, causing the cable ties 2 to break.

[0043] The breakage or slippage of one cable tie 2 often triggers a chain reaction of breakage or slippage of the remaining cable ties 2, ultimately causing the stacked boxes to become loose again. Due to the failure of the securement, the boxes are more likely to fall over during the next shaking, causing the items inside the boxes to collide with each other and cause unnecessary damage to the goods.

[0044] In view of this, the present application provides a fixing fixture for fixing a plurality of stacked boxes. For example, Figure 3 As shown, Figure 3 The fixture 100 includes a plurality of sub-fixing fixtures 3, wherein each sub-fixing fixture 3 includes a positioning structure 31 and a connecting structure pair 32. The sub-fixing fixtures 3 cooperate with each other to achieve tight fixation of the stacked boxes.

[0045] More specifically, Figure 4As shown. The positioning structure 31 includes two connected fixing plates 311. The positioning structure 31 is configured as follows: it is set at the contact vertices of the adjacent stacked boxes 1, and the two fixing plates 311 are respectively fitted with two connecting surfaces. The connecting surface is the surface where the adjacent stacked boxes meet, that is, Figure 4 The connecting structure pair 32 includes two connecting structures 321 , which are respectively connected to the side walls of the two fixing plates 311 . The connecting structure 321 is configured to connect to adjacent connecting structures 321 in other connecting structure pairs 32 .

[0046] Combine Figure 5 The installation position of the above positioning structure is explained as follows: In actual application, multiple boxes may be stacked up and down, for example Figure 4 Box A is stacked on box B, which is in turn stacked on box C. In this case, it is only necessary to fix the adjacent boxes to achieve the goal of fixing the multiple boxes stacked up and down into a stable whole.

[0047] The vertices in "arranging the positioning structures 31 at the contact vertices of the stacked adjacent boxes 1" refer to the places where three or more faces of the boxes are connected. Taking the box as a rectangular parallelepiped as an example, the number of vertices is 8. The contact vertices 11 of the adjacent boxes 1 refer to the places where three or more faces of the boxes are connected. Figure 4 The circled part.

[0048] by Figure 4 For example, Figure 4 Figure 2 shows two boxes stacked one on top of the other, with box A stacked on top of box B. Boxes A and B have four contact points, designated the first, second, third, and fourth vertices. The corresponding fixing fixture includes four sub-fixing fixtures 3, one located at each contact vertex between box A and box B. These are designated the first, second, third, and fourth sub-fixing fixtures.

[0049] More specifically, the positioning structure 31 in the first fixed sub-clamp is set at the first vertex, the positioning structure 31 in the second sub-fixed clamp is set at the second vertex, the positioning structure 31 in the third sub-fixed clamp is set at the third vertex, and the positioning structure 31 in the fourth sub-fixed clamp is set at the fourth vertex.

[0050] One of the connecting structures in the pair of connecting structures in the first fixed sub-clamp is connected to one of the connecting structures in the pair of connecting structures in the second fixed sub-clamp, and the other connecting structure in the pair of connecting structures in the first fixed sub-clamp is connected to one of the connecting structures in the pair of connecting structures in the third fixed sub-clamp. The other connecting structure in the pair of connecting structures in the third fixed sub-clamp is connected to one of the connecting structures in the pair of connecting structures in the fourth fixed sub-clamp, and the other connecting structure in the pair of connecting structures in the fourth fixed sub-clamp is connected to the other connecting structure in the pair of connecting structures in the second fixed sub-clamp.

[0051] Reference Figure 4 The positioning structure 31 of each sub-fixture 3 consists of two fixing plates 311, which fit tightly against the contact surfaces of adjacent boxes 1. This design allows adjacent boxes 1 to be "clamped" together by the positioning structure, increasing the contact area between layers and improving overall stability. The tight fit of the fixing plates 311 prevents the boxes 1 from moving or sliding on the contact surface, thereby ensuring vertical stability.

[0052] The two connecting structures 321 in the connecting structure pair 32 are respectively connected to the side walls of the fixed plate 311, acting as a bridge. Each pair of connecting structures is connected by adjacent sub-fixing clamps 3, forming a chain-like fixing method. This also allows the stacked boxes 1 to be tightly connected together through multiple fixing sub-clamps 3, ensuring overall unity and structural strength.

[0053] Because the positioning structure 31 and connecting structure pair 32 of each sub-fixing fixture 3 can cover the vertices and side walls of the two boxes, the entire stacked structure is actually fixed in multiple dimensions by the action of multiple sub-fixing fixtures 3. This multi-point fixing design not only increases the stability of the structure but also disperses the force, preventing deformation or slippage of the sub-fixing fixture 3 due to excessive force at a single point.

[0054] As a possible implementation, Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 The sub-fixing fixtures at different angles are shown. The positioning structure 31 includes two fixing plates 311, which are respectively referred to as a first fixing plate and a second fixing plate. The first fixing plate is vertically connected to the second fixing plate.

[0055] The first and second fixing plates are perpendicular to each other, respectively contacting two different surfaces of the adjacent box. Since boxes are typically rectangular or square, the vertical fixing plates 311 can cover two contacting corners of the box. This multi-faceted contact method effectively increases the number of fixing points and contact area, improving the fit of the sub-fixing fixture to the box and thus enhancing the stability of the fixation.

[0056] In addition, the vertically connected fixed plate design not only limits the sliding of adjacent boxes in the vertical direction, but also effectively prevents their relative displacement in the horizontal direction, thereby ensuring that each layer of boxes remains firmly in place and reducing relative movement caused by friction or vibration during transportation or handling.

[0057] Moreover, after the first fixing plate is vertically connected to the second fixing plate, an "L"-shaped structure is formed. This structure has strong bending and shear resistance in mechanical engineering. Compared with the single-direction fixing plate 311 design, the vertically connected double-plate structure can better withstand stress from pressures in different directions and reduce the risk of deformation or damage.

[0058] As a possible implementation method, the number of sub-fixtures is the same as the number of common vertices of adjacent stacked boxes. Figure 5 As shown, box A is adjacent to box B, and box A is stacked on top of box B. The number of common vertices between box A and box B is 4, and the number of sub-fixing fixtures used to fix box A and box B is also four.

[0059] As a possible implementation, the surface of the connecting structure closest to the case is coplanar with the surface of the connected fixing plate closest to the case. When the surfaces of the connecting structure and the fixing plate are coplanar and both closely contact the surface of the case, the fit of the entire fixing fixture to the case is significantly improved. This coplanar design ensures that the connecting structure and the fixing plate form a continuous force-bearing area on the surface of the case, preventing the possibility of loosening or falling off.

[0060] Because the connecting structure and the fixing plate are coplanar on the surface of the cabinet, the applied fixing force is evenly distributed on the connecting structure and the fixing plate, and thus acts on the cabinet. This avoids stress concentration caused by excessive force on a certain part, reduces the risk of damage to the cabinet surface, and extends the service life of the cabinet.

[0061] If the connection structure and the fixing plate are not coplanar, some protruding parts may rub against the surface of the box or get caught on other objects. The coplanar design effectively reduces the presence of such protruding parts, reducing the risk of friction and snagging damage.

[0062] As a possible implementation, Figure 8As shown, the dimension L1 of the fixing plate 311 in the first direction is greater than the dimension L2 of the connecting structure 321 connected to the fixing plate 311 in the first direction, and the dimension L3 of the fixing plate 311 in the second direction is greater than the dimension L4 of the connecting structure 321 connected to the fixing plate 311 in the second direction. The first direction is the stacking direction of the multiple boxes, that is, the vertical direction, and the second direction is perpendicular to the first direction.

[0063] The dimension L1 of the fixing plate 311 in the first direction is larger than the dimension L2 of the connecting structure 321 connected to the fixing plate 311 in the first direction, which means that the fixing plate 311 can provide a larger contact area. In the stacking direction, the larger fixing plate can cover more contact surfaces of adjacent boxes. The larger fixing plate can provide greater surface friction, effectively reducing the relative sliding of boxes caused by gravity or external forces, and further ensuring the stability of the stacking.

[0064] The larger fixing plate 311 provides more room for maneuvering during installation. Since the fixing plate 311 is relatively large in both the first and second directions, even if there is deviation during installation, the fixing effect will not be significantly affected. The larger fixing plate 311 provides stable alignment in multiple directions, reducing installation difficulties caused by inaccurate alignment. Furthermore, the larger size of the fixing plate 311 means it can accommodate boxes of varying sizes and shapes, increasing the versatility and flexibility of the fixing fixture.

[0065] Since the size of the fixing plate 311 is larger than the size of the connecting structure 321, the force applied to the fixing clamp can be more evenly distributed on the larger fixing plate 311. This design effectively disperses the stress and avoids stress concentration on the smaller connecting structure 321, thereby reducing the risk of deformation or damage to the local structure.

[0066] In some embodiments, as Figure 9 The connecting structure 321 includes a clustering device, which includes a housing 3211 and a retractable belt 3212 disposed in the housing. The housing 3211 is provided with an opening 3213 for accommodating the retractable belt 3212 to pass through. A hook 3214 is provided at the end of the retractable belt 3212 passing through the opening 3213.

[0067] The housing 3211 of the collimator is used to protect the structure inside the housing, such as the telescopic belt 3212. The telescopic belt 3212 can be freely extended and retracted through the opening 3213 to achieve extension and shortening. The end of the telescopic belt 3212 is provided with a hook 3214, which is used to connect with the hook at the end of the telescopic belt of the connecting structure in the adjacent remaining connecting structures, thereby forming a chain-like fixing method, so that the stacked boxes are tightly connected together through multiple fixing sub-clamps, such as Figure 10 shown.

[0068] The good ductility of the telescopic belt 3212 enables it to be compatible with boxes of different sizes. The telescopic belt 3212 in the cluster can be extended or shortened as needed to adapt to boxes of different sizes and various stacking methods.

[0069] As a possible implementation, Figure 11 As shown, the width of hook 3214 is greater than the width of opening 3213. When the fixing clamp is not needed, the telescopic band will retract. When the width of hook 3214 is greater than the width of opening 3213, hook 3214 can be stuck in opening 3213, preventing the entire telescopic band from being submerged in the housing. When the user needs to use the fixing clamp, they can simply pull the hook 3214 to pull the telescopic band out of opening 3213, which facilitates operation and optimizes the user experience.

[0070] In some embodiments, combined Figure 12 and Figure 13 , Figure 12 and Figure 13 The internal components of the beam collector are shown from different angles. Also located within the housing 3211 are a roller 3215, a spiral spring 3216, and a fixed post 3217. The fixed post 3217 is connected to the housing 3211 and extends through the roller 3215. The spiral spring 3216 is wrapped around the fixed post 3217, with one end connected to the fixed post 3217 and the other end connected to the inner wall of the roller 3215. The stretch band 3212 is wrapped around the outer wall of the roller 3215, with one end connected to the roller 3215 and the other end extending through the opening 3213.

[0071] Fixed post 3217 is connected to housing 3211 and extends through roller 3215. Fixed post 3217 supports and secures roller 3215. Fixed post 3217 ensures roller 3215 can rotate freely around fixed post 3217 and provides structural support for spiral spring 3216. Fixed post 3217 provides an axis around which spiral spring 3216 and roller 3215 rotate, acting as a core support.

[0072] Roller 3215 is the component that wraps around the stretch band 3212 and rotates to extend and retract the stretch band 3212. The rotation of roller 3215 is controlled by a spiral spring 3216, ensuring that the stretch band 3212 can be extended when in use and automatically retracted when not in use. For example, when the stretch band 3212 needs to be extended, roller 3215 rotates clockwise, pulling the stretch band 3212 out of the opening 3213 in the housing 3211. When the external force is released, the spiral spring 3216 provides a counter-torque, pushing roller 3215 to rotate counterclockwise, automatically retracting the stretch band 3212.

[0073] The spiral spring 3216 is a key component providing tension. One end of the spiral spring is connected to the fixed post 3217, and the other end is connected to the inner wall of the roller 3215. When the stretch band 3212 is pulled out, the spiral spring 3216 is gradually tightened, generating a torsional force. The twisted spiral spring 3216 stores elastic potential energy. When the external force is released, that is, when the user stops pulling the stretch band 3212 and the hook at the end of the stretch band 3212 is not connected, the tension of the spiral spring 3216 begins to act on the roller 3215, releasing the stored energy and driving the roller 3215 to rotate in the opposite direction, retracting the stretch band 3212.

[0074] The stretch strap 3212 is used to secure the case directly. One end is connected to the roller 3215, and the other end passes through the opening 3213 in the housing 3211. The user adjusts the length of the stretch strap by stretching it to ensure that the stretch strap 3212 is tightly wrapped around the case. To secure the case, the user pulls the stretch strap 3212 out of the housing 3211 and secures it with the hook. Once secured, the tension of the spiral spring 3216 keeps the stretch strap 3212 taut, ensuring a secure hold.

[0075] The spiral spring 3216 design allows the retractable band 3212 to automatically retract into the housing 3211 when no longer in use, reducing the number of steps required and improving ease of use. Furthermore, this automatic tightening feature ensures the retractable band remains in a closed position, preventing loosening or slipping, and enhancing secure fixation.

[0076] Because the roller 3215, spiral spring 3216, and retractable band 3212 are all centrally located within the housing 3212, the entire device is compact and easy to carry and store. When the retractable band 3212 is retracted, the entire device occupies less space, making it suitable for applications requiring frequent securing and release, and providing greater convenience for storage and transportation.

[0077] Since the user only needs to simply pull out the telescopic belt 3212 and fix it without complicated installation and adjustment, and the length of the telescopic belt 3212 can be freely adjusted according to actual needs, it can adapt to boxes of different sizes and shapes, increasing the flexibility of the fixing clamp.

[0078] The design within the housing reduces wear and tear on the expansion strap 3212. The stable structure of the roller 3215 and the fixing post 3217 ensures that the expansion strap 3212 is protected from excessive friction and damage during repeated extension and retraction, thereby extending the life of the fixing fixture. Furthermore, the expansion strap 3212 wraps around the roller 3215 and automatically tightens, ensuring uniform distribution of the fixing force across the housing surface and preventing damage to the housing or the fixing fixture due to localized stress concentration.

[0079] As a possible implementation manner, the winding direction of the spiral spring is the same as the winding direction of the telescopic band. For example, the winding direction of the spiral spring and the winding direction of the telescopic band are both counterclockwise.

[0080] The present application also provides a packaging structure, for example, Figure 14 and Figure 15 As shown, Figure 14 and Figure 15 The packaging structure 200 is shown from different angles. The packaging structure 200 comprises a plurality of stacked boxes 1 and at least one fixing fixture 100 as described above. Figure 14 and Figure 15 One fixing fixture 100 is required for two stacked boxes 1. When N stacked boxes 1 need to be fixed, N-1 fixing fixtures 100 are required. The positioning structures 31 in each sub-fixing fixture 3 in the fixing fixture 100 are respectively positioned at the contacting vertices of adjacent stacked boxes 1, and the two fixing plates 311 are respectively in contact with the two contacting surfaces. The connecting structures 321 in each sub-fixing fixture 3 in the fixing fixture 100 are connected to adjacent connecting structures 321 in other connecting structure pairs 32.

[0081] The fixing plate of each of the multiple sub-fixing clamps 3 can cover two contacting corners of the box body 1 respectively. This multi-faceted contact method effectively increases the number of fixing points and the contact area, improves the fit between the sub-fixing clamp 3 and the box body, and thus improves the stability of the fixation. When the sub-fixing clamp 3 is connected to the sub-fixing clamp 3, the connection structure and the surface of the fixing plate are coplanar, and both are tightly attached to the surface of the box body, the fit between the entire fixing clamp and the box body is significantly increased. This coplanar design ensures that the connection structure and the fixing plate form a continuous force-bearing area on the surface of the box body, avoiding the possibility of loosening or falling off.

[0082] Because the connecting structure and the fixing plate are coplanar on the surface of the cabinet, the applied fixing force is evenly distributed on the connecting structure and the fixing plate, and thus acts on the cabinet. This avoids stress concentration caused by excessive force on a certain part, reduces the risk of damage to the cabinet surface, and extends the service life of the cabinet.

[0083] In the case of stacking more boxes (more than two boxes), for example, three boxes: box A, box B, and box C are stacked on each other, such as Figure 16 As shown. Each fixing clamp 100 fixes two adjacent boxes 1 together to ensure a firm connection between them. When two adjacent boxes are fixed by the clamps, the fixing force is transmitted to the upper and lower boxes 1 through the contact surface. Since the force can be transmitted to the entire stacking structure through the contact and fixation between adjacent boxes, there is no need to set up a separate fixing clamp 100 for each box. N boxes 1 stacked on top of each other only require N-1 fixing clamps 100, which not only simplifies the installation process, but also reduces the number of clamps, reducing material and installation costs.
