Description

Technical Field

[0001] The present application relates to the technical field of packaging protection, and in particular to an anti-dumping device and a packaging box. Background Art

[0002] In the design of cabinets, data centers, refrigeration and other system products, there are a lot of narrow and high product designs due to objective requirements such as space and environment. Because the products cannot be placed flat, the packaging designed according to the products must be highly consistent with the narrow and high design of the products in order to save storage and logistics resources. In the logistics and transportation environment, there are often factors such as sudden braking of vehicles, improper loading and unloading of goods, uneven ground and too high center of gravity of products, which leads to a greater risk of tipping over of this type of narrow and high packaging during logistics and transportation. Once a tipping accident occurs, it will cause damage to the product at the least and injury to people at the worst, which is a very high safety risk.

[0003] In the process of realizing this application, the inventors found that there are at least the following problems in the prior art: At present, the protection of packaging dumping in the packaging industry is mainly divided into additional fixation of easy-to-dump packaging during logistics and warehousing, and the affixing of anti-dumping labels. It is difficult to standardize the additional fixing method, and it is difficult to standardize the product packaging fixing method during the packaging design stage. At the same time, most packaging and transportation accidents occur during the loading and unloading stages and without effective fixation. Therefore, this protection method cannot completely prevent the occurrence of dumping accidents. For the anti-dumping labels used by the mainstream industry, they can only serve as a warning before dumping and identification and accountability after dumping. They cannot fundamentally solve the problem of packaging dumping, let alone prevent the occurrence of dumping problems. Summary of the invention

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

[0034] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit the implementation of this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0037] In the description of this application, 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 direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] See also Figure 1The packaging box 1 of the embodiment of the present application is in the shape of a rectangular parallelepiped as a whole, 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 is much greater than its width. For example, the width of the product corresponding to the packaging box 1 in this embodiment is only about 30% of the height. In order to prevent the product from tipping over during transportation and storage after being packaged in the packaging box 1, most of the time, a method of joint packaging using multiple devices is used to increase the width of the packaging box 1, thereby reducing the probability of tipping over. However, this packaging method cannot completely avoid the problem of tipping over of the product and the packaging box 1. At the same time, this packaging method often cannot match the needs of customers well or cannot meet the delivery requirements of orders, and is not convenient for sales. If a single device is enlarged for packaging, the packaging cost will be greatly increased, and a large amount of storage and logistics space will be occupied, resulting in an increase in logistics costs.

[0039] In order to solve the above problems, eliminate the safety hazards during product transportation and storage, and at the same time maintain a low cost, the inventor has developed an anti-dumping device of the embodiment of the present application. The anti-dumping device can be used for the above-mentioned packaging box 1. At the same time, it is also suitable for other packaging boxes and products with anti-dumping requirements.

[0040] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the packaging box 1 at least includes a first surface 11 and a second surface 12 that are arranged opposite to each other. The first surface 11 and the second surface 12 are two surfaces that are prone to tipping. For example, when the width of the packaging box 1 in this embodiment is much smaller than the height, the first surface 11 and the second surface 12 are two side surfaces of a rectangular parallelepiped, the short side of the side surface is the long side of the bottom rectangle of the rectangular parallelepiped, and the long side of the side surface is the side where the height of the rectangular parallelepiped is located. The packaging box 1 of this structure may tip over toward the first surface 11 or the second surface 12. Therefore, in order to increase the safety of the product during storage and transportation, an anti-tipping device may be installed on the first surface 11 and the second surface 12, respectively. Of course, if the safety and reliability are to be further enhanced, and when the long side of the bottom surface of the packaging box 1 is long or the product weight is heavy, two or more anti-dumping devices can be respectively arranged in parallel on the first surface 11 and the second surface 12. If there is a possibility of dumping in the other two directions of the packaging box 1, one or more anti-dumping devices can also be respectively arranged on the other two side surfaces. The specific number of devices to be used 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-dumping device of the embodiment of the present application includes a dumping trigger 4, a dumping support 2 and a support rod 3. The two ends of the support rod 3 are respectively provided with a dumping trigger 4 and a dumping support 2, wherein the dumping trigger 4 is arranged at the bottom of the packaging box 1, and the dumping support 2 is arranged at the top of the packaging box 1. The dumping 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, and the first end 31 is rotatably connected to the base 24; the second end 32 and the dumping trigger 4 are provided with a locking structure for use in conjunction. The dumping trigger 4 is used to trigger the locking structure to open when the object tilts toward the side where the anti-dumping device is provided, 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 above-mentioned packaging box 1 or other items with anti-dumping requirements. The tipping trigger 4 is used to immediately trigger the locking structure to open when the object tilts, so as to release the support rod 3, and the support rod 3 rotates around the base 24 of the tipping support 2 to open, forming a support point for the object, so that the object can stand at a certain tilt angle and will not tip directly to the ground. The overall structure of the anti-tipping device of this embodiment is a mechanical structure without electronic components, no additional power source is required, and no energy is consumed. 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 piece 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 piece 21 close to the base 24. The potential energy device is used to provide the rotational power of the support rod 3 so that the support rod 3 can be rotated and opened 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), so that the hinge piece 21 and the base 24 are installed with the rotating shaft ends facing upward and the unfixed end of the support rod 3 facing downward. In some embodiments, the potential energy device may not be installed. When the locking structure releases the support rod 3, since the object is in a tilted state at this time, the support rod 3 can be rotated outward by gravity. After the potential energy device is installed, the support rod 3 can be opened more quickly, so that the safety and reliability of the anti-tipping device are better. There is no requirement for the specific structure of the potential energy device, as long as it can provide power for the support rod 3 to rotate outward. For example, a torsion spring 25 can be installed on the rotating shaft of the hinge 21 and 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 cause the support rod 3 to open quickly outward.

[0043] In order to further enhance the safety and reliability of the anti-dumping device and prevent the support rod 3 from rebounding after opening outward, a non-return structure can also be installed on the dumping support 2. The non-return structure is used to make the support rod 3 only rotate in the direction of opening relative to the base 24 when the locking structure releases the support rod 3, but not rotate in the direction of closing relative to the base 24. The non-return structure can be used as long as it can achieve the non-return function, and the specific structure is not limited. For example, the non-return structure can include a ratchet 23 and a non-return plate 22. The ratchet 23 is fixed to the top of the base 24 and is located outside the rotating shaft hole at both ends of the base 24. The non-return plate 22 is arranged at one end of the support rod 3 close to the base 24 (the top of the first end 31), and a ratchet 221 is provided at one end of the non-return plate 22 close to the ratchet 23. The ratchet 221 and the ratchet 23 are used to limit the support rod 3 to only rotate in the direction of opening relative to the base 24. That is, the pawl 221 can only rotate outward (in the opening direction) along the teeth of the ratchet wheel 23, and the pawl 221 will be stuck by the teeth of the ratchet wheel 23 when rotating inward. In order to facilitate the separation of the pawl 221 from the ratchet wheel 23 and to facilitate the reset of the support rod 3 to close with the base 24, a reset device can be provided. For example, a mounting hole 211 can be provided at the corresponding positions of the hinge 21 and the ratchet wheel 23, and the two ends of the check plate 22 (in this case, in order 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 in sequence) are respectively inserted into the corresponding mounting holes 211, and a connecting rod 222 is provided at the bottom of the check plate 22, and a spring member 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), and the connecting rod 222 with a spring member 223 is installed in the mounting groove. The spring member 223 is always in a compressed state. When the check plate 22 is not subjected to other external forces, the spring member 223 always applies an upward thrust to the connecting rod 222, pushing the check plate 22 so that the ratchet 23 and the pawl 221 cooperate. When the check plate 22 is pulled downward, the check plate 22 compresses the spring and moves downward, so that the ratchet 23 and the pawl 221 are separated, so that the support rod 3 can be rotated inward to reset. The above-mentioned check structure is only a specific implementation method. In actual applications, other check structures can be used as long as the function of preventing the support rod 3 from rebounding after opening can be achieved, and the specific structure is not limited. For example, the check plate 22 can be designed as a two-piece type, with the ends of the two check plates that are away from each other respectively inserted into the mounting holes 211 of the hinge plate 21, and the ends of the two check plates that are close to each other connected with elastic reset devices, and the bottom connecting rods 222 of the two check plates are located in the mounting groove at the top of the first end 31 of the support rod 3, and can slide in the mounting groove. When the two ends of the check plate 22 are pressed to make the two check plates shrink inward (i.e. move in the direction of approaching each other), the pawl 221 on the check plate can be separated from the ratchet 23, and when the two ends of the check plate 22 are not pressed, the spring elastic force resets the two check plates, and the pawl 221 engages with the ratchet 23.Specifically, the specific structures of the check structure and its reset device are not listed one by one.

[0044] like Figure 6 and Figure 7 As shown, in the present embodiment, the tipping trigger 4 specifically includes a base 41, a mounting seat 42, a pull rod 43 and a locking block 44. The mounting seat 42 is arranged in the middle of the base 41 and is rotatably connected to the base 41. When no other limiting members are arranged on the mounting seat 42, the mounting seat 42 can realize a 180° rotation in the middle of the base 41, that is, the rotation axis of the mounting seat 42 and the base 41 is arranged along the width direction of the base 41. The locking block 44 is arranged at one end of the mounting seat 42 close to the support rod 3 and is slidably connected to the mounting seat 42. For example, a first slide groove 421 can be arranged on the mounting seat 42, and the locking block 44 is penetrated in the first slide groove 421 and can slide up and down along the first slide 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. In order to make the pulling of the pull rod 43 smoother, a pull rod 43 can be provided on both sides of the mounting seat 42, and the two pull rods 43 are symmetrically arranged, one end of the pull rod 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 clamping block 442 can be provided at the end of the locking block 44, and a second slide groove 431 can be correspondingly provided on the pull rod 43. The root of the clamping block 442 is located in the second slide groove 431. When the pull rod 43 is pulled, the clamping block 442 can slide in the second slide groove 431. The mounting seat 42 is used to be installed on the tilting side of the object, and rotates synchronously with the object when the object tilts. The rotation of the mounting seat 42 drives the pull rod to rotate relative to the base 41, and the rotation of the pull rod 43 drives the locking block 44 to slide relative to the mounting seat 42, so that the locking block 44 extends out of the end of the mounting seat 42 or retracts into the end of the mounting seat 42.

[0045] like Figure 3 and Figure 5As shown, correspondingly, a snap ring 33 can be provided at one end of the support rod 3 near the tipping trigger 4, and the snap ring 33 can be made of metal material. The snap ring 33 is used to accommodate a locking block 44 protruding from the end of the mounting seat 42. When the locking block 44 protrudes from the top of the mounting seat 4 and enters the snap 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 seat 42, it is no longer possible to apply force to the support rod 3, and the support rod 3 can be opened to the outside by the elastic force of the potential energy device. In order to facilitate the locking block 44 to enter and exit the snap ring 33, a tip 441 can be provided at the top of the locking block 44. When the support rod 3 is closed relative to the base 24, the distance between the tip 441 and the surface of the support rod 3 gradually decreases from the top to the root end (that is, the surface of the tip 441 close to the support rod 3 is inclined relative to the support rod 3). In order to prevent the support rod 3 from damaging the support surface when it is triggered to open, a soft pad 34 may be provided at the bottom of the support rod 3. The pad 34 may be, for example, an EVA (ethylene-vinyl acetate copolymer) pad. In order to make the locking block 44 more stable and reliable when locked and to prevent the locking block 44 from being retracted into the mounting seat 42 due to factors such as accidents, an elastic reset member 443 may be provided at the bottom of the locking block 44. The elastic reset member 443 may be, for example, a spring. The spring is always in a compressed state and always gives the locking block 44 an upward thrust, making the locking action of the locking block 44 more reliable.

[0046] like Figure 2 As shown, in some embodiments, the anti-dumping device may further include a stopper 5, which is used to limit the rotation angle of the support rod 3 relative to the base 24. For example, a connecting rope may be provided, one end of which is fixed to the surface of the support rod 3 close to the base 24, and the other end is fixed to the surface of the packaging box 1 on the side where the anti-dumping device is provided. When the support rod 3 is rotated 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 2, the length of the connecting rope can be set according to the size of the specific 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, the longer the distance d between the bottom of the support rod 3 and the supporting point O of the packaging box 1, the greater the additional stability of the packaging box 1, but 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 gravity acceleration time is, the greater the speed of the support rod 3 when it touches the ground, and the higher the load of the support rod 3. At the same time, the farther the bottom of the support rod 3 is from the bottom supporting point of the packaging box 1, the greater the torque that needs to be offset will be generated, and the static load will also increase accordingly. Therefore, a suitable α angle should be selected to make the support rod 3 bear the force vertically to prevent the support rod 3 from breaking. To cope with the slope, it is best to make the value of tanα (i.e., the ratio of the distance d between the bottom of the support rod 3 and the supporting point O of the packaging box 1 to the supporting height h of the support rod 3 when the support rod 3 is in the supporting state d / h) slightly larger 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 limiter 5 limits the support rod 3 to open to the maximum angle, try to keep the support rod 3 perpendicular to the supporting surface.

[0048] During installation, the side surface of the base 24 away from the support rod 3 is fitted with the inclined side surface of the packaging box 1, and the base 24 is fixed to the upper part of the side surface of the packaging box 1 by screws and other connecting parts. The mounting seat 42 is fitted on the lower part of the side surface of the packaging box 1, and the pull rod 43 is set on the side close to the packaging box 1, and the base 41 is pressed on the bottom of the packaging box 1. When the packaging box 1 is placed upright, the surfaces of the mounting seat 42 and the base 41 are perpendicular to each other. One or more anti-dumping devices are respectively set on the opposite two sides or four sides of the packaging box 1 as needed.

[0049] The working principle of the anti-dumping device and the packaging box 1 in the embodiment of the present application is as follows: when the packaging box 1 tilts toward the side where the anti-dumping 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 seat 42 to rotate together, while the base 41 remains stationary, and the mounting seat 42 rotates to cause the pull rod 43 to rotate accordingly. At the same time, the pull rod 43 pulls the locking block 44 to retract into the mounting seat 42. When the locking block 44 is completely retracted into the mounting seat 42, the locking structure opens, and the bottom end of the support rod 3 loses its locking effect. The top of the support rod 3 is opened outward relative to the base 24 by the thrust of the potential energy device. After opening to the maximum angle limited by the limit member 5, the non-return structure is stuck to prevent the support rod 3 from rebounding. At this time, the support rod 3 can stably support the packaging box 1.

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

[0051] During normal freight transportation, the dumping support that stores a certain amount of elastic potential energy and the connected support rod are locked by the dumping trigger. The dumping trigger has an anti-accidental touch function and will not be triggered by the vibration of conventional transportation. When tilting occurs, the sheet metal pull rod releases the dumping support that stores a certain amount of elastic potential energy, driving the support rod to rotate outward and pop out, reaching the preset angle before the dumping expands, and quickly stops through the stop connection rope to form a stable triangular structure to prevent the dumping from continuing to expand. When on-site personnel find that the supported equipment has tilted, they can push it straight and push the support rod back to the locked state of the anti-dumping trigger to complete the return of the anti-dumping device. At this time, the anti-dumping device can deal with the next possible dumping.

[0052] After the packaging box is installed with the anti-dumping device of the embodiment of the present application, the problem of the packaging box completely dumping due to human negligence, unexpected circumstances, etc. can be fundamentally prevented from occurring, and the accident can be suppressed in time in the early stages of the accident, thereby reducing the occurrence of losses.

[0053] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0054] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
