[0001] The invention belongs to the technical field of circulation boxes, and in particular relates to a transportation shockproof circulation box. Background Art

[0002] Express recycling boxes are boxes that can be recycled between express parcels. They are generally made of a plastic called polypropylene (PP) or wood, which can be reused and recycled many times. In the express delivery industry, the trend of using recycling boxes is increasing because it has the following advantages: Express recycling boxes are more environmentally friendly. Using recycling boxes can reduce the use of cardboard boxes and foam plastics, reduce environmental pollution; at the same time, it also saves costs. The recycling boxes can be maintained and repaired after multiple uses, reducing transportation costs.

[0003] In order to prevent damage to the goods when using this type of express recycling box, the goods need to be packaged. For some easily damaged items, it is also necessary to wrap the goods with cushioning pads or cushioning foam, and then put the goods into the packaging box. However, packaging boxes are needed for packaging every time they are transported, and packaging boxes made of plastic or wooden boards need to be filled with more foam boards and other objects for cushioning. Both of these will cause excessive packaging and waste, and the filled foam boards are difficult to clean after use, and disassembly and assembly are more troublesome.

[0004] Based on this, a transport shockproof circulation box is proposed which can be recycled and does not need to be filled with foam boards or buffer pads when in use. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a transport shockproof circulation box.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A transport and shockproof circulation box of the present invention includes a box body and a box cover, wherein two buffer components, a load-bearing plate and a load-bearing belt are arranged in the box body, the two buffer components are respectively rotatably connected to the inner side walls on both sides of the box body, the load-bearing belt is passed through the load-bearing plate, and the two sides of the load-bearing belt are respectively wrapped around the outer side surfaces of the two buffer components to the top and buckled to the inner side surfaces of the buffer components, the load-bearing plate carries the object suspended in the air and pulls the buffer component to rotate and abut against the side of the object for collision prevention and shock reduction of the object.

[0008] Furthermore, the buffer assembly includes two rocker arms, the tops of the two rocker arms are rotatably connected to the inner side walls of the box body, a plurality of rotating shafts are provided on the rocker arms, a plurality of rotating shafts are provided with slots, and the carrying belt is buckled on the slots.

[0009] Furthermore, the carrying belts are respectively buckled on the rotating shafts of the two buffer components at different heights to accommodate objects with different centers of gravity.

[0010] Furthermore, a buffer ring is provided on the rotating shaft, and the buffer ring is used to abut against the surface of an object.

[0011] Furthermore, the buffer ring is rotatably disposed on the rotating shaft, and a torsion spring is disposed between the buffer ring and the rotating shaft.

[0012] Furthermore, a plurality of the buffer rings are provided on each of the rotating shafts, and the directions of the torsion springs connected to the plurality of buffer rings are alternately arranged in opposite directions.

[0013] Furthermore, it also includes two adjustment rods and an adjustment block, wherein the adjustment block is slidably arranged on the inner side walls on both sides of the box body, and the two adjustment rods are respectively rotatably connected to the adjustment blocks and are respectively located on both sides of the bearing plate.

[0014] Furthermore, a spring and an adjustment plate are provided on the box cover, the adjustment plate is slidably provided on the box cover, the spring is connected between the inner wall of the box cover and the adjustment plate, and the adjustment plate cooperates with the supporting plate and the supporting belt to resist the force on the object for buffering and shock absorption.

[0015] Furthermore, the adjustment plates are provided in two groups, the contact surfaces of the two groups of adjustment plates with the object are inclined surfaces, and the two groups of adjustment plates are horizontally slidably provided on the box cover.

[0016] Furthermore, the two groups of adjustment plates are arranged opposite to each other and are arranged in a cross direction with the arrangement directions of the two oppositely arranged buffer components.

[0017] The beneficial effects of the present invention are:

[0018] (1) By arranging two buffer components, a load-bearing plate and a load-bearing belt in the circulation box, after placing the goods on the load-bearing plate, gravity will pull the load-bearing belt downward, and the load-bearing belt will further pull the buffer component to rotate, so that the bottom of the buffer component rotates and lifts up, until the bottom of the buffer component abuts against the two side surfaces of the goods. Due to the weight of the goods themselves, when the weight is heavy, the load-bearing belt is pulled and the buffer component abuts against the two sides of the goods with a greater force, and when the weight of the goods is light, the force of the buffer component abutting against the side of the goods is also smaller. When the goods are transported by a transport vehicle, the suspended load-bearing plate and load-bearing belt will ensure that the goods will not hit the bottom of the box directly, and the abutment of the buffer components on both sides against the goods can maintain the balance of the goods in the circulation box, thereby ensuring to the greatest extent that the goods will not be damaged during transportation;

[0019] (2) The carrying belts are buckled on the rotating shafts of two buffer components at different heights to accommodate objects with different centers of gravity. When the center of gravity of the heavy packaged goods is biased to one side, the carrying belt on that side is buckled on the slot of the lower rotating shaft. Since the buckling position is lower, the carrying belt pulls the buffer component at a larger angle and the force arm is longer. Therefore, the buffer component on that side has a greater contact force on the goods. The carrying belt on the other side is buckled on the slot of the higher rotating shaft. Since the carrying belt pulls the buffer component at a smaller angle and the force arm is shorter, the buffer component has a smaller contact force on the goods. By adjusting the different forces on both sides of the goods, the goods can be prevented from tipping over during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] like Figure 1-5As shown, a transport shockproof circulation box of the present invention comprises a box body 1 and a box cover 2, two buffer components, a bearing plate 3 and a bearing belt 4 are arranged in the box body 1, the two buffer components are respectively rotatably connected to the inner side walls on both sides of the box body 1, the bearing belt 4 is passed through the bearing plate 3, and the two sides of the bearing belt 4 are respectively wrapped around the outer side surfaces of the two buffer components to the top and buckled to the inner side surfaces of the buffer components, the bearing plate 3 carries the object suspended in the air and pulls the buffer component to rotate and abut against the side surface of the object for anti-collision and shock reduction of the object;

[0029] In order to prevent the goods from being damaged during transportation, the goods need to be packaged. For some easily damaged items, it is necessary to wrap the goods with cushioning pads or cushioning foam, and then put the goods into the packaging box. However, packaging boxes are needed for packaging every time they are transported. Generally, the packaging boxes are corrugated boxes or wooden boxes. Corrugated boxes are easily damaged during use. Therefore, when packaging medium and large goods, corrugated boxes are generally used once. Packing boxes made of wooden boards need to be filled with more foam boards and other objects for cushioning. Both will cause excessive packaging and waste, and the filled foam boards are difficult to clean after use, which causes many problems during use.

[0030] In order to solve the problem raised, two buffer components are arranged in the circulation box, and holes or grooves for the carrying belt 4 to pass through are arranged on the carrying plate 3. When in use, the carrying belt 4 passes through the carrying plate 3, and then the two ends of the carrying belt 4 go around the outer side of the buffer component and surround the top of the buffer component, and then continue to surround the inner side of the buffer component, and buckle on the inner side of the buffer component, so that the carrying plate 3 is horizontally suspended in the box body 1, and then the goods to be packaged are placed on the carrying plate 3. Since the top of the buffer component is rotatably connected to the two sides of the inner side of the box body 1, after the goods are placed on the carrying plate 3, the gravity will pull the carrying belt 4 downward, and the carrying belt 4 further pulls the buffer component to rotate, so that The bottom of the buffer assembly rotates and lifts until the bottom of the buffer assembly abuts against the two side surfaces of the goods. Due to the weight of the goods themselves, when the weight is heavy, the carrying belt 4 is pulled and the buffer assembly abuts against the two sides of the goods with a greater force. When the weight of the goods is light, the force with which the buffer fault part abuts against the side of the goods is also smaller. When the goods are transported by a transport vehicle, when passing through a bumpy road section, the up and down bumps will cause the goods to move up and down. The suspended carrying plate 3 and carrying belt 4 will ensure that the goods will not directly hit the bottom of the box body 1, and the abutment of the buffer assemblies on both sides against the goods can maintain the balance of the goods in the circulation box, thereby ensuring to the greatest extent that the goods will not be damaged during transportation.

[0031] Since the volume and weight of goods vary, in order to meet the requirements of packaging goods of more sizes, weights and types, in one embodiment, the buffer assembly includes two swing rods 5, the tops of the two swing rods 5 are rotatably connected to the inner side walls of the box body 1 on both sides, and the swing rods 5 are provided with a plurality of rotating shafts 6, and the plurality of rotating shafts 6 are provided with slots, and the carrying belt 4 is buckled on the slots;

[0032] A set of three rotating shafts 6 on a buffer component are arranged in sequence and rotatably arranged on two swing rods 5, and the slots are arranged on the lower side of the rotating shaft 6, so that in the initial state of the buffer component, the three rotating shafts 6 on the swing rod 5 are arranged in sequence from top to bottom. When packaging objects of smaller size, the carrying belt 4 can be buckled on the slots of the rotating shaft 6 at a lower position to avoid a large swing amplitude of the goods due to a larger activity space. When packaging goods of larger size, the carrying belt 4 can be buckled on the slots of the rotating shaft 6 at a higher position. When packaging goods of heavier weight, the carrying belt 4 can be buckled on the slots of the rotating shaft 6 at a lower position. Since the weight of the goods itself has a greater pulling force on the carrying belt 4, when buckled on the slots at a lower position, since the force arm is longer and the pulling point is closer to the contact point with the goods, the buffer component can be abutted against the side wall of the goods with greater force. The above method is used to achieve adaptation when packaging objects of different sizes and weights.

[0033] In some usage scenarios, some heavier instruments or equipment need to be transported, and the center of gravity of some instruments or equipment is not at the center of the equipment. After placing them on the carrying plate 3, the center of gravity will be unstable, causing the equipment to tilt after placement. There may be safety hazards during transportation, and the equipment may also tip over and be damaged. In order to avoid this problem, through the circulation box structure in the above embodiment, the carrying belt 4 can also be buckled on the rotating shafts 6 of different heights of the two buffer components to adapt to objects with different centers of gravity;

[0034] When the center of gravity of the heavy object of the packaged goods is biased to one side, the carrying belt 4 on this side is buckled on the card slot of the lower rotating shaft 6. Due to the lower buckling position, the carrying belt 4 pulls the buffer assembly at a larger angle and the force arm is longer. Therefore, the buffer assembly on this side has a greater abutment force on the goods, while the carrying belt 4 on the other side is buckled on the card slot of the higher rotating shaft 6. Since the carrying belt 4 pulls the buffer assembly at a smaller angle and the force arm is shorter, the abutment force of the buffer assembly on the goods is also smaller. By buckling the two sides of the carrying belt 4 at different heights on the buffer assembly, different forces on the two sides of the goods can be adjusted to prevent the goods from tipping over during transportation. At the same time, if the box body 1 in the inner circulation box is in an inclined state due to the unstable center of gravity of the goods, one side of the box body 1 will be subjected to force for a long time during long-term transportation, and the service life of the box body 1 will be greatly reduced. Therefore, by adjusting the center of gravity of the goods by the carrying belt 4, the service life of the circulation box can also be improved.

[0035] Since the carrying belt 4 is passed through the carrying plate 3, and when the cargo on the carrying plate 3 is an object whose center of gravity is not in the center position, after the carrying belt 4 is adjusted to be buckled on the rotating shaft 6 at different heights, the carrying plate 3 is not in the center position of the carrying belt 4. Therefore, the carrying belt 4 is slidably passed through the carrying plate 3. At the same time, in order to prevent the carrying plate 3 from sliding with the carrying belt 4 due to force during transportation, causing the cargo to tip over, a fixed structure is provided between the carrying belt 4 and the carrying plate 3, which is used to fix the carrying plate 3 after the adjustment of the carrying belt 4 is completed to prevent it from being displaced.

[0036] In order to further improve the shock-absorbing effect on the goods, an elastic mechanism can be provided on the rocker arm 5 so that the rotating shaft 6 is slidably provided on the rocker arm 5, and the elastic mechanism abuts against the sliding direction of the rotating shaft 6. The elastic mechanism can be used to adjust the size of the carrying belt 4 and improve the shock-absorbing force. At the same time, it can also make it easier for the carrying belt 4 to pull up the buffer assembly.

[0037] Furthermore, a buffer ring 61 is provided on the rotating shaft 6, and the buffer ring 61 is used to abut against the surface of an object; the rotating shaft 6 is fixedly connected to the rocker arms 5 on both sides, and the top of the rocker arms 5 is rotatably connected to the two inner walls of the box body 1, and each rotating shaft 6 is divided into multiple sections, including a buffer section and a slot section, and the buffer section and the slot section are arranged at intervals on the rotating shaft 6, and a buffer ring 61 is provided on the buffer section. The buffer ring 61 is made of elastic material. In order to avoid the collision of the goods after the buffer component abuts against the goods, and in order to further improve the protection effect of the goods by the buffer component, after the buffer ring 61 is provided on the rotating shaft 6, the buffer ring 61 abuts against the goods, which can not only avoid the collision of the goods surface, but also further improve the buffering and shock-absorbing effect of the goods.

[0038] Furthermore, the buffer ring 61 is rotatably arranged on the rotating shaft 6, and a torsion spring 22 is arranged between the buffer ring 61 and the rotating shaft 6; since the goods are subject to not only large vibrations and bumps during transportation, but also high-frequency and small-amplitude vibrations of the transport vehicle itself, when the transported goods are relatively precise instruments or equipment, the bumps and vibrations will cause damage to them, so the buffer ring 61 is able to rotate on the rotating shaft 6, and the buffer ring 61 has not only elastic force, but also large friction force. At the same time, the torsion spring 22 is connected between the rotating shaft 6 and the buffer ring 61. When the surface of the buffer ring 61 abuts against the surface of the goods, since the buffer ring 61 has a large friction force, when the goods are bumped up and down during transportation, the buffer ring 61 will rotate synchronously with the up and down movement of the goods, and after the buffer ring 61 rotates to one side, the torsion spring 22 connected to the buffer ring 61 will form a stored force, and the stored force direction of the torsion spring 22 is vertically upward. Since the buffer ring 61 has friction force, The torsion spring 22 can also be used to adjust the number of connections between the buffer ring 61 and the torsion spring 22 according to actual conditions to adjust the buffering effect on the goods. When there is a large bump during transportation, the carrying belts 4 and the rotating shaft 6 on both sides cooperate with the buffer ring 61. The gravity generated by the bump will make the rotating shaft 6 pulled up by the carrying belts 4 on both sides fit more closely with the goods, and the tighter fit will increase the friction between the buffer ring 61 on the rotating shaft 6 and the surface of the goods. The increase in friction can make the torsion spring 22 exert a greater buffering force, avoiding the buffer ring 61 and the surface of the goods slipping due to insufficient friction when used to package goods with relatively smooth surfaces, resulting in failure to play a buffering role. At the same time, since the structure of the buffer ring 61 and the torsion spring 22 used for buffering and shock absorption is relatively simple, the cost is relatively low.

[0039] Specifically, in one embodiment, a plurality of buffer rings 61 are provided on each rotating shaft 6, and the directions of the torsion springs 22 connected to the plurality of buffer rings 61 are alternately arranged in opposite directions; since there are more than one buffer ring 61 on a rotating shaft 6, and the direction of the bumping of the goods during transportation is to move up and down reciprocatingly, after a plurality of buffer rings 61 and torsion springs 22 are provided on the rotating shaft 6, the setting directions of the plurality of torsion springs 22 are different, and the torsion directions of the large torsion springs 22 arranged at intervals on the rotating shaft 6 are opposite, so that after the plurality of buffer rings 61 on the rotating shaft 6 abut against the surface of the goods, in addition to being able to provide an upward force, they can also provide a downward force. After the shaft 6 abuts against the surface of the goods, when the goods bump up and down, the vibration amplitude can be greatly reduced from both the upper and lower directions. The buffer ring 61 and the torsion spring 22 can also provide partial bearing capacity in cooperation with the carrying belt 4. Moreover, the heavier the goods, the greater the force of the shaft 6 abutting against the surface of the goods, and the greater the friction force of the buffer ring 61 on the surface of the goods, and the greater the vertical support force of the goods transmitted by the friction force. Since the vibrations in both the upper and lower directions when the goods bump up and down will have greater resistance from the buffer ring 61 and the torsion spring 22, most of the low-frequency vibrations can be reduced, and the internal structure of the equipment installed with precision instruments can be largely prevented from being damaged.

[0040] In general, the buffer spring 22 on the bottommost rotating shaft 6 only needs to abut against the surface of the goods. However, there are some irregular goods. Therefore, buffer rings 61 and torsion springs 22 are also provided on the rotating shafts 6 at different heights to fix the goods and provide buffering and shock-absorbing effects when dealing with irregular goods.

[0041] In one embodiment, it also includes two adjusting rods 7 and an adjusting block, the adjusting block is slidably arranged on the inner side walls of both sides of the box body 1, and the two adjusting rods 7 are respectively rotatably connected to the adjusting block and are respectively located on both sides of the bearing plate 3;

[0042] Due to the different sizes of goods, in order to ensure the applicability of the carrying belt 4, it is necessary to ensure the length of the carrying belt 4. When the circulation box is used to pack light and large goods, in order to ensure that there is enough packaging space, the carrying belt 4 needs to be buckled on the slot of the highest rotating shaft 6, which may cause the carrying plate 3 to touch the bottom. In this case, the problem of poor buffering and shock absorption effect will occur. Therefore, an adjustment block and an adjustment rod 7 are provided between the buffer assembly and the carrying plate 3. The position of the adjustment rod 7 moves with the movement of the adjustment block, and the adjustment rod 7 is rotatably arranged on the adjustment blocks on both sides so that the carrying belt 4 abuts against the adjustment rod 7. When it is necessary to adjust the length of the carrying belt 4, the adjusting rod 7 is used to move the carrying belt 4 toward the inner side of the box body 1 to raise the carrying plate 3 at the bottom of the carrying belt 4 to avoid touching the bottom.

[0043] Since the goods are buffered and shock-absorbed by the buffer assembly, the carrying belt 4 and the carrying plate 3, and when the top is unconstrained, the top of the goods will swing along with the movement of the transport vehicle, making the top of the goods prone to bumping, a spring 22 and an adjustment plate 21 are provided on the box cover 2, the adjustment plate 21 is slidably provided on the box cover 2, the spring 22 is connected between the inner side wall of the box cover 2 and the adjustment plate 21, and the adjustment plate 21 cooperates with the carrying plate 3 and the carrying belt 4 and resists the force of the object for buffering and shock absorption;

[0044] Before placing the goods in the box body 1, first adjust the buckling position of the carrying belt 4 and the position of the adjusting rod 7. After the adjustment is completed, place the goods on the carrying plate 3, and then close the box cover 2. When the box cover 2 is provided with an adjusting plate 21 and a spring 22, the spring 22 provides elastic force to the adjusting plate 21, so that the adjusting plate 21 abuts against the top of the goods, and a downward force is applied to the goods through the adjusting plate 21. The amplitude of the up and down movement of the goods can be reduced through the adjusting plate 21, and the constraints on both sides of the goods by the carrying belt 4 and the buffer assembly are combined to limit the goods in the vertical and horizontal directions, and the adjusting plate 21 can have a large friction force. Therefore, after the adjusting plate 21 abuts against the goods, the friction force can prevent the top of the goods from swinging.

[0045] Specifically, two groups of adjustment plates 21 are provided, and the contact surfaces of the two groups of adjustment plates 21 with the objects are inclined surfaces, and the two groups of adjustment plates 21 are horizontally slidably arranged on the box cover 2. When the two groups of adjustment plates 21 are inclined surfaces, the friction between the contact surfaces of the adjustment plates 21 and the surface of the goods is small. When the transportation is bumpy, the goods move up and down in the circulation box. The up and down movement of the goods will push the adjustment plates 21 to both sides in the horizontal direction, and the springs 22 connected to the adjustment plates 21 will give the adjustment plates 21 a buffering force. At the same time, the buffering force of the adjustment plates 21 can cooperate with the actions of the buffer assembly, the load-bearing plate 3 and the load-bearing belt 4 when the box cover 2 is closed, so that the goods are always wrapped and limited by the adjustment plates 21, the buffer assembly, the load-bearing plate 3 and the load-bearing belt 4 in the circulation box, which can prevent them from displacement and tilting.

[0046] At the same time, the two groups of adjustment plates 21 are arranged opposite to each other and are cross-arranged with the setting directions of the two oppositely arranged buffer components; that is, from the top view perspective of the box body 1 and the box cover 2, the buffer components are arranged on the left and right sides thereof, and the adjustment plates 21 are arranged on the upper and lower sides thereof, forming a limit for the X-axis direction of the goods by the buffer components, the carrying plates 3 and the carrying belts 4, and the adjustment plates 21 form a limit for the Y-axis direction of the goods, thereby avoiding large swaying of the goods during transportation.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
