Description

Technical Field

[0001] This application relates to the field of packaging protection technology, and in particular to an anti-tipping device and a packaging box. Background Technology

[0002] In the design of systems such as server racks, data centers, and cooling systems, numerous narrow and tall designs exist due to objective requirements such as space and environment. Because these products cannot be laid flat, packaging designed to save warehousing and logistics resources must closely match their narrow and tall dimensions. However, in the logistics and transportation environment, factors such as sudden vehicle braking, improper loading and unloading operations, uneven ground, and a high center of gravity of the product often lead to a significant risk of tipping over during transport. Once a tipping accident occurs, it can result in damage to the product or, in severe cases, personal injury, posing an extremely high safety risk.

[0003] In the process of developing this application, the inventors discovered at least the following problems with the existing technology: Currently, the packaging industry mainly protects against packaging tipping by additionally securing easily tipping packaging during logistics and warehousing, and affixing anti-tipping labels. Standardizing additional securing methods is difficult, making it hard to regulate product packaging securing methods during the packaging design stage. Furthermore, most packaging transportation accidents occur during loading and unloading, and when effective securing is not implemented. Therefore, this protective method cannot completely prevent tipping accidents. As for the anti-tipping labels used in the industry, they only serve as a warning before tipping and for identifying and assigning responsibility after tipping; they cannot fundamentally solve the problem of packaging tipping, nor can they prevent tipping from occurring. Summary of the Invention

[0004] Based on this, this application provides an anti-tipping device and a packaging box to fundamentally solve the problem of packaging box tipping in the prior art and prevent tipping accidents.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] On one hand, embodiments of this application provide an anti-tipping device, including a support rod, a tipping trigger disposed at the bottom of the support rod, and a tipping support disposed at the top of the support rod;

[0007] The tipping support includes a base, and the support rod includes a first end and a second end opposite to each other. The first end is rotatably connected to the base; the second end is provided with a locking structure that cooperates with the tipping trigger.

[0008] The tilt trigger is used to open the locking structure when the object tilts toward the side where the anti-tipping device is provided, so that the support rod rotates and opens relative to the base, thereby supporting the object.

[0009] In one embodiment, the tilting support further includes a hinge and a potential energy device; the hinge is rotatably connected to the base, and the first end is fixedly connected to the hinge; the potential energy device is used to provide rotational power to the support rod so that the support rod rotates open relative to the base.

[0010] In one embodiment, the potential energy device includes a torsion spring.

[0011] In one embodiment, the tilting support further includes a check mechanism that, when the locking mechanism is open, allows the support rod to rotate only in the direction relative to the opening of the base.

[0012] In one embodiment, the check valve structure includes a ratchet and a check plate. The ratchet is fixed to the top of the base, and the check plate is disposed at one end of the support rod near the base. The end of the check plate near the ratchet is provided with a pawl. The pawl and the ratchet are used to limit the support rod to rotate only in the direction that is open relative to the base.

[0013] In one embodiment, the tilt trigger includes a base, a mounting base, a pull rod, and a locking block; the mounting base is rotatably connected to the base; the locking block is located at one end of the mounting base near the support rod and is slidably connected to the mounting base; the mounting base is used to be installed on the tilting side of the object and drives the pull rod by rotating synchronously with the object, so that the locking block extends out of the end of the mounting base or retracts into the end of the mounting base.

[0014] In one embodiment, the support rod has a retaining ring at one end near the tilt trigger, the retaining ring being used to accommodate the locking block protruding from the end of the mounting base.

[0015] In one embodiment, the anti-tipping device further includes a limiting member for limiting the angle of rotation of the support rod relative to the base.

[0016] In one embodiment, the limiting member restricts the support rod from opening to its maximum angle, ensuring that the support rod remains perpendicular to the support surface.

[0017] On the other hand, embodiments of this application provide a packaging box including the anti-tipping device described above.

[0018] In one embodiment, the packaging box includes at least a first surface and a second surface disposed opposite to each other, and the first surface and the second surface are respectively provided with the anti-tipping device;

[0019] The tilt trigger includes a base and a mounting base that are rotatably connected. The upper portions of the first surface and the second surface are respectively fixed with the base, and the lower portions of the first surface and the second surface are respectively fixed with the mounting base. The base is located at the bottom of the packaging box.

[0020] This application has at least the following beneficial effects: The anti-tipping device provided in this application includes a tipping trigger, a tipping support, and a support rod. The tipping trigger is located at the bottom of the anti-tipping device, and the tipping support is located at the top of the anti-tipping device. When an object tilts, the locking structure of the tipping trigger is triggered to open. After the locking structure opens, the support rod rotates relative to the base and opens. The support rod and the bottom edge of the object work together to support the object, effectively preventing the object from falling and causing an accident. The anti-tipping device in this application fundamentally solves the problem of object tipping, and can support the object in time when it tilts, preventing it from falling and causing an accident. The packaging box provided in this application includes the above-mentioned anti-tipping device, and therefore also has the above-mentioned beneficial effects. Attached Figure Description

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] Please see Figure 1In this embodiment, the packaging box 1 is generally rectangular in shape and is mainly used for packaging refrigeration-related equipment. Due to the special requirements of refrigeration-related equipment, the product cannot be laid flat during transportation and storage, and the height of the product itself far exceeds its width. For example, in this embodiment, the width of the product corresponding to packaging box 1 is only about 30% of its height. To prevent the product from tipping over during transportation and storage after packaging box 1 is used, multiple pieces of equipment are often packaged together to increase the width of packaging box 1, thereby reducing the probability of tipping. However, this packaging method cannot completely prevent the product and packaging box 1 from tipping over. At the same time, this packaging method often cannot well match customer needs or meet order delivery requirements, making it inconvenient for sales. If a larger packaging method is used for a single piece of equipment, it will greatly increase the packaging cost and occupy a large amount of warehousing and logistics space, leading to increased logistics costs.

[0039] To solve the above problems and eliminate safety hazards during product transportation and storage, while maintaining low costs, the inventors developed the anti-tipping device according to the embodiments of this application. The anti-tipping device can be used in the above-mentioned packaging box 1, and it is also applicable to other packaging boxes and products with anti-tipping requirements.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the packaging box 1 includes at least a first surface 11 and a second surface 12 arranged opposite to each other. The first surface 11 and the second surface 12 are two surfaces that are prone to tipping over. For example, when the width of the packaging box 1 in this embodiment is much smaller than its height, the first surface 11 and the second surface 12 are respectively two sides of a cuboid, with the short side of the side being the long side of the base rectangle of the cuboid, and the long side being the side containing the height of the cuboid. The packaging box 1 with this structure may tip over towards the first surface 11 or towards the second surface 12. Therefore, to increase the safety during product storage and transportation, an anti-tipping device can be installed on each of the first surface 11 and the second surface 12. Of course, to further enhance its safety and reliability, and when the bottom side of the packaging box 1 is long or the product is heavy, two or more anti-tipping devices can be set side by side on the first surface 11 and the second surface 12 respectively. If there is also a possibility of tipping in the other two directions of the packaging box 1, one or more anti-tipping devices can be set on the other two sides respectively. The specific number can be selected according to the specific size, shape and weight of the packaging box 1.

[0041] like Figure 1 and Figure 3As shown, the anti-tipping device of this embodiment includes a tipping trigger 4, a tipping support 2, and a support rod 3. The support rod 3 has a tipping trigger 4 and a tipping support 2 at both ends, respectively. The tipping trigger 4 is located at the bottom of the packaging box 1, and the tipping support 2 is located at the top of the packaging box 1. The tipping support 2 includes a base 24, and the support rod 3 includes a first end 31 and a second end 32 opposite to each other. The first end 31 is rotatably connected to the base 24; the second end 32 has a locking structure that cooperates with the tipping trigger 4. The tipping trigger 4 is used to trigger the locking structure to open when an object tilts towards the side where the anti-tipping device is located, so that the support rod 3 rotates open relative to the base 24, thereby supporting the object. The object here can be, for example, the aforementioned packaging box 1 or other items requiring anti-tipping protection. The tilt trigger 4 is used to immediately trigger the locking structure to open when the object tilts, thereby releasing the support rod 3. The support rod 3 rotates around the base 24 of the tilt support 2 to open, forming a support point for the object, so that the object remains standing at a certain tilt angle and does not tip over directly to the ground. The anti-tipping device in this embodiment has an entirely mechanical structure with no electronic components, requires no additional power source, and does not consume energy. Its anti-tipping method is safe and reliable.

[0042] like Figure 4 and Figure 5 As shown, in this embodiment, the tipping support 2 includes a base 24, a hinge 21 rotatably connected to the base 24, and a potential energy device. The first end 31 of the support rod 3 is fixed to the inner wall of the hinge 21 near the base 24. The potential energy device provides rotational power to the support rod 3, enabling it to rotate and open relative to the base 24. During installation, the base 24 can be installed on the upper part of the tipping side surface of the packaging box 1 (such as the first surface 11 or the second surface 12 of the packaging box 1 in this embodiment), with the hinge 21 and the pivot end of the base 24 facing upwards and the unfixed end of the support rod 3 facing downwards. In some embodiments, the potential energy device may not be installed. When the locking structure releases the support rod 3, the support rod 3 can rotate outwards and open by gravity because the object is in a tilted state. Installing the potential energy device allows the support rod 3 to open more quickly, improving the safety and reliability of the anti-tipping device. The specific structure of the potential energy device is not required, as long as it can provide the outward rotational power of the support rod 3. For example, a torsion spring 25 can be installed on the hinge 21 and the pivot of the base 24. One side of the torsion spring 25 abuts against the base 24, and the other side abuts against the support rod 3. When the bottom of the support rod 3 is released, the elastic force of the torsion spring 25 can make the support rod 3 open outward quickly.

[0043] To further enhance the safety and reliability of the anti-tipping device and prevent the support rod 3 from rebounding after opening outwards, a check structure can be installed on the tipping support 2. This check structure ensures that when the locking structure releases the support rod 3, it can only rotate in the direction relative to the opening of the base 24, and cannot rotate in the direction relative to the closing of the base 24. The check structure only needs to achieve the check function; its specific structure is not limited. For example, the check structure can include a ratchet 23 and a check plate 22. The ratchet 23 is fixed to the top of the base 24, located around the pivot holes at both ends of the base 24. The check plate 22 is located at the end of the support rod 3 near the base 24 (the top of the first end 31). The end of the check plate 22 near the ratchet 23 has a pawl 221. The pawl 221 and the ratchet 23 are used to limit the rotation of the support rod 3 to the direction relative to the opening of the base 24. That is, the pawl 221 can only rotate outward (in the opening direction) along the teeth of the ratchet 23. When rotating inward, the pawl 221 will be stuck by the teeth of the ratchet 23. To facilitate the separation of the pawl 221 from the ratchet 23 and to facilitate the return of the support rod 3 to the base 24, a reset device can be provided. For example, a mounting hole 211 can be provided at the corresponding position of the hinge 21 and the ratchet 23. The two ends of the check plate 22 (in this case, to facilitate the installation of the check plate 22 on the hinge 21, the check plate 22 can be designed as a split type, for example, the check plate 22 is formed by splicing two or more sections of plates) are respectively inserted into the corresponding mounting holes 211. The bottom of the check plate 22 is provided with a connecting rod 222, and a spring 223 is sleeved on the connecting rod 222. The top of the first end 31 of the support rod 3 is provided with a mounting groove (not shown). The connecting rod 222, which is fitted with a spring element 223, is installed in the mounting groove. The spring element 223 is always in a compressed state. When the check plate 22 is not subjected to other external forces, the spring element 223 always applies an upward pushing force to the connecting rod 222, pushing the check plate 22 and engaging the ratchet 23 and the pawl 221. When the check plate 22 is pulled downward, the check plate 22 compresses the spring and moves downward, causing the ratchet 23 and the pawl 221 to separate, thereby allowing the support rod 3 to be rotated inward and reset. The above-described check structure is only one specific implementation method. In practical applications, other check structures can be used, as long as they can achieve the function of preventing the support rod 3 from springing back after opening. The specific structure is not limited. For example, the check plate 22 can be designed as a two-piece plate, with the ends of the two check plates far apart inserted into the mounting holes 211 of the hinge plate 21, and the ends of the two check plates close to each other connected to an elastic reset device. The bottom connecting rod 222 of the two check plates is located in the mounting groove at the top of the first end 31 of the support rod 3 and can slide within the mounting groove. When the two ends of the check plate 22 are pressed, causing the two check plates to retract inward (i.e. move towards each other), the pawl 221 on the check plate can be separated from the ratchet 23. When the two ends of the check plate 22 are not pressed, the spring force resets the two check plates, and the pawl 221 engages with the ratchet 23.Specifically, the specific structures of the check valve and its reset device will not be listed one by one.

[0044] like Figure 6 and Figure 7 As shown, in this embodiment, the tilt trigger 4 specifically includes a base 41, a mounting base 42, a pull rod 43, and a locking block 44. The mounting base 42 is located in the middle of the base 41 and is rotatably connected to the base 41. When no other limiting components are provided on the mounting base 42, the mounting base 42 can rotate 180° in the middle of the base 41, that is, the rotation axis of the mounting base 42 and the base 41 is set along the width direction of the base 41. The locking block 44 is located at one end of the mounting base 42 near the support rod 3 and is slidably connected to the mounting base 42. For example, a first groove 421 can be provided on the mounting base 42, and the locking block 44 passes through the first groove 421 and can slide up and down along the first groove 421. One end of the pull rod 43 is rotatably connected to the base 41, and the other end is slidably connected to the locking block 44. To make the pulling of the lever 43 smoother, a lever 43 can be set on each side of the mounting base 42, with the two levers 43 symmetrically arranged. One end of the lever 43 is rotatably connected to the base 41, and the other end is slidably connected to the end of the locking block 44. For example, a locking block 442 can be set at the end of the locking block 44, and a second sliding groove 431 can be set on the lever 43 accordingly. The root of the locking block 442 is located in the second sliding groove 431. When the lever 43 is pulled, the locking block 442 can slide in the second sliding groove 431. The mounting base 42 is used to be installed on the tilting side of the object and rotates synchronously with the object when it tilts. The rotation of the mounting base 42 causes the lever to rotate relative to the base 41, and the rotation of the lever 43 causes the locking block 44 to slide relative to the mounting base 42, so that the locking block 44 extends out of the end of the mounting base 42 or retracts into the end of the mounting base 42.

[0045] like Figure 3 and Figure 5As shown, a retaining ring 33 can be provided at one end of the support rod 3 near the tilt trigger 4. The retaining ring 33 can be made of metal. The retaining ring 33 is used to accommodate the locking block 44 protruding from the end of the mounting base 42. When the locking block 44 protrudes from the top of the mounting base 42 and enters the retaining ring 33, it can be used to close the support rod 3 relative to the base 24. When the locking block 44 retracts into the mounting base 42, it is no longer possible to apply force to the support rod 3, and the support rod 3 can be opened outward by the elastic force of the potential energy device. To facilitate the entry and exit of the locking block 44 from the retaining ring 33, a pointed tip 441 can be provided on the top of the locking block 44. When the support rod 3 is closed relative to the base 24, the distance between the pointed tip 441 and the surface of the support rod 3 gradually decreases from the top to the bottom (i.e., the surface of the pointed tip 441 near the support rod 3 is inclined relative to the support rod 3). To prevent damage to the support surface when the support rod 3 is triggered to open, a soft pad 34 can be added to the bottom of the support rod 3. This pad 34 can be, for example, an EVA (ethylene-vinyl acetate copolymer) pad. To make the locking block 44 more stable and reliable when locking, and to prevent the locking block 44 from retracting into the mounting base 42 due to accidents or other factors, an elastic reset element 443 can be provided at the bottom of the locking block 44. The elastic reset element 443 can be, for example, a spring. The spring is always in a compressed state, always providing an upward thrust to the locking block 44, making the locking action of the locking block 44 more reliable.

[0046] like Figure 2 As shown, in some embodiments, the anti-tipping device may further include a limiting member 5, which is used to limit the angle of rotation of the support rod 3 relative to the base 24. For example, a connecting rope can be provided, with one end fixed to the surface of the support rod 3 near the base 24 and the other end fixed to the surface of the packaging box 1 on the side where the anti-tipping device is located. When the support rod 3 rotates outward to a certain angle, the connecting rope is straightened, and the support rod 3 cannot continue to rotate outward, thereby limiting the rotation angle of the support rod 3.

[0047] Please continue reading Figure 2The length of the connecting rope can be specifically set according to the dimensions of the packaging box 1 and the weight of the product. As shown in the figure, when the support rod 3 supports the packaging box 1, the larger the angle α between the support rod 3 and the surface of the packaging box 1, and the longer the distance d from the bottom of the support rod 3 to the support point O of the packaging box 1, the greater the additional stability obtained by the packaging box 1. However, the longer d is, the greater the torque generated by the support rod 3. Under the same weight, the longer d is, the larger α is; under the same initial velocity, the longer the acceleration time due to gravity, the greater the velocity of the support rod 3 when it touches the ground, and the higher the load on the support rod 3. At the same time, the farther the bottom of the support rod 3 is from the bottom support point of the packaging box 1, the greater the torque that needs to be offset, and the static load will also increase accordingly. Therefore, an appropriate angle α should be selected to ensure that the support rod 3 is subjected to vertical force and to prevent the support rod 3 from breaking. To handle sloping conditions, it is best to make the value of tanα (i.e., the ratio of the distance d from the bottom of the support rod 3 to the support point O of the packaging box 1 to the support height h of the support rod 3, d / h) slightly greater than H / D, where H is the height of the packaging box 1 and D is the width of the packaging box 1. When the limiting member 5 restricts the support rod 3 from opening to its maximum angle, it should keep the support rod 3 as perpendicular to the support surface as possible.

[0048] During installation, the surface of the base 24 furthest from the support rod 3 is aligned with the inclined surface of the packaging box 1, and the base 24 is fixed to the upper part of that side surface of the packaging box 1 using screws or other connectors. The mounting base 42 is fitted against the lower part of that side surface of the packaging box 1, and the pull rod 43 is located on the side closest to the packaging box 1. The base 41 is pressed against the bottom of the packaging box 1. When the packaging box 1 is placed upright, the surfaces of the mounting base 42 and the base 41 are perpendicular to each other. One or more anti-tipping devices may be installed on opposite sides or all four sides of the packaging box 1 as needed.

[0049] The working principle of the anti-tipping device and packaging box 1 in this embodiment is as follows: When the packaging box 1 tilts to the side where the anti-tipping device is provided, that is, the packaging box 1 rotates with the bottom support side, the surface of the packaging box 1 pushes the mounting base 42 to rotate together, while the base 41 remains stationary. The rotation of the mounting base 42 causes the pull rod 43 to rotate as well. At the same time, the pull rod 43 pulls the locking block 44 to retract into the mounting base 42. When the locking block 44 is fully retracted into the mounting base 42, the locking structure opens, the bottom end of the support rod 3 loses its locking function, and the top of the support rod 3 opens outward relative to the base 24 under the thrust of the potential energy device. After opening to the maximum angle limited by the limiting member 5, the check structure locks, preventing the support rod 3 from rebounding. At this time, the support rod 3 can provide stable support for the packaging box 1.

[0050] All components of the anti-tipping device provided in this application embodiment are mechanical structural parts. Its judgment on the tipping of the packaging box does not need to be completed by electronic components. It is based entirely on mechanical and mechanical principles, which has high reliability and can effectively prevent the packaging box from tipping over.

[0051] During normal freight transport, the tilt support, which stores a certain amount of elastic potential energy, and the connected support rod are locked by the tilt trigger. The tilt trigger has an anti-accidental trigger function and will not be triggered by vibrations during normal transportation. When tilting occurs, the sheet metal tie rod releases the tilt support, which stores a certain amount of elastic potential energy, causing the support rod to rotate outward and pop out, reaching a preset angle before the tilt escalates. It then quickly stops via the stop rope, forming a stable triangular structure to prevent the tilt from escalating further. When on-site personnel discover the tilted supported equipment, they can push it back to its original position and return the support rod to the locked state of the anti-tilt trigger, completing the return of the anti-tilt device to its original position. At this point, the anti-tilt device can handle the next possible tilt.

[0052] After the anti-tipping device of this application embodiment is installed on the packaging box, it fundamentally prevents the packaging box from tipping over completely due to human negligence, accidents, or other reasons. It can suppress the accident in the early stage and reduce the loss.

[0053] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
