[0021] Further technical solution: A sealing strip is provided at the door frame of the box body, and the sealing strip is communicated with the inner cavity of the hydraulic box.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the box body is bumped while moving forward, the baffle plate is forced to compress the elastic telescopic rod. Under the push of the baffle plate, the transmission assembly pushes the column rod downward, and the column rod pushes the positioning seat through the limit assembly. All the positioning seats further clamp and limit the goods. Under the further thrust of the baffle plate, all the supporting mechanisms shrink, and all the goods and the storage racks are lowered at the same time, thereby lowering the center of gravity of the box body and improving the stability of the box body. In this process, the column rod can drive the adsorption force of the adsorption mechanism to increase, increase the adsorption force on the door panel, increase the overall stability of the box body, and thus increase the compressive resistance of the box body.

[0024] 2. A buffer assembly is provided at the bottom of the rack, and the buffer assembly is provided in the groove cavity. When the box moves, the fluidity of water can reduce the vibration force of the rack during the movement. When the baffle is hit, the column rod drives the buffer assembly to move downward. At this time, the buoyancy of water can reduce the impact force of the baffle. At the same time, the buffer assembly can stabilize the water flow in the corresponding groove cavity to prevent the unstable water flow from affecting the overall stability of the box;

[0025] 3. When the baffle is under pressure, it drives the hydraulic mechanism to increase the water pressure in all water bags, thereby increasing the stability of the cargo. At the same time, the contact between the water bags and the cargo can cool the surface of the cargo, thus avoiding the risk of spontaneous combustion caused by frictional heat during the vibration of the cargo.

[0026] 4. On the one hand, holding water in the water tank can increase the stability of the box during its movement; on the other hand, when the box tilts forward under the impact force, the water flow in the water tank will be concentrated on one side. In the present invention, when the gravity of the water flow in the groove cavity near the baffle side exceeds the limit value, the sealing cover plate on the upper part of the guide groove is opened, and the water flow is introduced from the guide groove to the storage box through the connecting pipe, thereby preventing the water flow from flowing to the side of the baffle when the baffle is subjected to force, causing the center of gravity of the box to be unstable;

[0027] 5. The water tank can guide the water into the hydraulic mechanism, and the hydraulic mechanism transfers the water in the water tank to the water bag, increasing the contact effect between the water bag and the goods and improving the vibration reduction ability of the water bag. Since the obstacles are generally close to the bottom of the box, the goods close to the bottom of the box are likely to be the first to be subjected to a greater impact force. By changing the intercepting area of ​​the one-way water outlet valve on each water pipe, the filling speed of the water into each water bag can be adjusted, thereby adjusting the vibration resistance of the goods on the rack at different heights.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1-Figure 8 As shown, a road cargo transport logistics box provided by the present invention comprises a box body 1, a water tank 2 is arranged at the bottom of the box body 1, a baffle 11 is connected to the outer wall of the box body 1, the baffle 11 is fixedly connected to the outer wall of the box body 1 by an elastic telescopic rod 10, a storage rack 12 is vertically slidably connected to the inner end surface of the box body 1, the storage rack 12 has a plurality of storage plates in the vertical direction, and a support mechanism 3 for vertically limiting the storage rack 12 is arranged between the storage rack 12 and the inner wall of the box body 1;

[0040] The water tank 2 is divided into a plurality of grooves 13 by a partition, and the bottoms of the grooves 13 are interconnected. A buffer assembly 4 is provided at the bottom of the storage rack 12, and the buffer assembly 4 is slidably connected in a groove 13; a column 14 is vertically slidably connected to the inner end surface of the box body 1, and a No. 3 spring 18 is provided between the column 14 and the inner end surface of the box body 1, and a plurality of positioning seats 15 are vertically slidably connected to the column 14, and a limiting assembly 6 for vertically limiting the positioning seat 15 is provided between the positioning seat 15 and the column 14, and each positioning seat 15 is correspondingly arranged on the upper side of a storage plate, and a transmission assembly 9 for pushing the column 14 to move downward is provided between the baffle 11 and the column 14;

[0041] The inner top surface of the box body 1 is connected with an adsorption mechanism 7, which can adsorb and fix the door panel of the box body 1. When the column 14 moves downward, the column 14 can drive the adsorption force of the adsorption mechanism 7 to increase. A hydraulic mechanism 8 is arranged between the baffle 11 and the water tank 2. The lower bottom surface of the positioning seat 15 is provided with a water bag 16. The hydraulic mechanism 8 can increase the water pressure in the water bag 16.

[0042] A reflux mechanism 5 is disposed at the bottom of the box body 1 , and the reflux mechanism 5 can stabilize the water flow in the water tank 2 when the baffle plate 11 is hit.

[0043] In this embodiment, when in use, water is filled in the water tank 2 to increase the stability of the box 1 during movement, and then the goods are placed on the various storage plates of the built-in shelf 12 of the box 1, and then all the limit components 6 are adjusted, and all the limit components 6 push the positioning seats 15 connected to them to vertically limit the goods, and then the door panel of the box 1 is closed, and the adsorption mechanism 7 further adsorbs and fixes the door panel.

[0044] When the box 1 is bumped while moving forward, the baffle 11 is forced to compress the elastic telescopic rod 10. Under the push of the baffle 11, the transmission assembly 9 pushes the column 14 downward, and the column 14 pushes the positioning seat 15 through the limit assembly 6. All the positioning seats 15 further clamp and limit the goods. Under the further thrust of the baffle 11, all the supporting mechanisms 3 shrink, and all the goods together with the storage rack 12 are lowered at the same time, thereby lowering the center of gravity of the box 1 and improving the stability of the box 1. In this process, the column 14 can drive the adsorption force of the adsorption mechanism 7 to increase, increase the adsorption force on the door panel, increase the overall stability of the box 1, and thus increase the compressive strength of the box 1.

[0045] The bottom of the storage rack 12 is provided with a buffer component 4, which is arranged in the groove cavity 13. When the box body 1 moves, the fluidity of water can reduce the vibration force of the storage rack 12 during the movement. When the baffle 11 is hit, the column 14 drives the buffer component 4 to move downward. At this time, the buoyancy of water reduces the impact force of the baffle 11. At the same time, the buffer component 4 can stabilize the water flow in the corresponding groove cavity 13 to prevent the unstable water flow from affecting the overall stability of the box body 1.

[0046] When the baffle 11 is under pressure, the baffle 11 drives the hydraulic mechanism 8 to increase the water pressure in all the water bags 16, thereby increasing the stability of the cargo. At the same time, the contact between the water bags 16 and the cargo can cool the surface of the cargo, thereby avoiding the risk of spontaneous combustion caused by frictional heat during the vibration of the cargo.

[0047] When the box 1 tilts forward under the impact force, the water flow in the water tank 2 will be concentrated on one side, making the center of gravity of the box 1 unstable. When the water pressure on the side of the water tank 2 close to the baffle 11 reaches the limit, the reflux mechanism 5 can stabilize the water flow in the water tank 2 when the baffle 11 is hit.

[0048] like Figure 7 As shown, a road cargo transport logistics box provided by the present invention, the support mechanism 3 includes a fixing rod 31, a support seat 32, a No. 1 spring 33, an elastic telescopic seat 34 and a tooth plate 35;

[0049] The bottom of the storage plate on the storage rack 12 is fixedly connected with a plurality of fixing rods 31, and the inner wall of the box body 1 is vertically slidably connected with a plurality of support seats 32. The fixing rods 31 are correspondingly slid and connected through the support seats 32. The outer part of the fixing rods 31 is sleeved with a No. 1 spring 33, and the lower side of the support seat 32 is provided with an elastic telescopic seat 34, one end of the elastic telescopic seat 34 is fixedly connected to the inner wall of the box body 1, and the other end of the elastic telescopic seat 34 is fixedly connected with a tooth plate 35, and the tooth plate 35 can be elastically engaged with the side end surface of the support seat 32.

[0050] In this embodiment, during the movement of the box body 1, all the support seats 32 elastically support the storage rack 12 together. At this time, the buffer assembly 4 is in the groove cavity 13, and the vibration force exerted on the storage rack 12 is reduced by the buffer assembly 4; when the baffle 11 is hit, the transmission assembly 9 pushes the column rod 14 to move downward, and the column rod 14 drives the column rod 14 to push the goods. At this time, the support seat 32 is driven downward under the thrust of the No. 1 spring 33, and the elastic telescopic seat 34 drives the tooth plate 35 to elastically limit the support seat 32. At this time, the storage rack 12 and all the goods are lowered, thereby lowering the center of gravity of the box body 1; the impact force of the baffle 11 is reduced under the action of the resistance of the water flow and the elastic resistance of the tooth plate 35.

[0051] like Figure 8 As shown, a road freight transport logistics box provided by the present invention, the buffer assembly 4 includes a vertical rod 41 and a perforated plate 42, the bottom of the storage rack 12 is fixedly connected with the vertical rod 41, and the vertical rod 41 is vertically fixedly connected with a plurality of perforated plates 42, and the perforated plates 42 can be vertically slidably connected with the inner wall of the groove cavity 13.

[0052] In this embodiment, under normal conditions, part of the orifice plates 42 are in water. When the rack 12 vibrates, the orifice plates 42 move back and forth in the water, driving the water flow, and reducing the vibration force of the rack 12 through the water flow resistance. When the rack 12 moves downward, the rack 12 drives the remaining orifice plates 42 to be immersed in the water in turn through the vertical rods 41, and the upward resistance of the water flow gradually increases, thereby increasing the reduction of the impact force on the baffle 11.

[0053] like Figure 5 As shown, a road freight transport logistics box provided by the present invention, the reflux mechanism 5 includes a guide groove 51, a connecting pipe 52 and a storage box 53;

[0054] A guide groove 51 and a storage box 53 are provided at the bottom of the box body 1. The guide groove 51 is provided at an end close to the baffle 11, and the storage box 53 is provided at an end away from the baffle 11. A connecting pipe 52 is connected between the guide groove 51 and the storage box 53. A sealing cover plate is elastically connected to the top of the guide groove 51. When the water pressure at the upper part of the guide groove 51 reaches a limited value, the water flow in the water tank 2 is introduced into the guide groove 51.

[0055] In this embodiment, when the gravity of the water flow in the groove cavity 13 close to the side of the baffle 11 exceeds the limit value, the sealing cover plate on the upper part of the guide groove 51 is opened, and the water flows from the guide groove 51 through the connecting pipe 52 into the storage box 53, thereby preventing the water from flowing to the side of the baffle 11 when the baffle 11 is subjected to force, thereby preventing the center of gravity of the box body 1 from being unstable.

[0056] like Figure 8 As shown, a road freight transport logistics box provided by the present invention, the limit assembly 6 includes a boss 61, a No. 2 spring 62 and a limit bolt 63, the column 14 is located at the lower side of each positioning seat 15 The portion of the boss 61 is fixed, the portion of the column 14 located on the upper side of the positioning seat 15 is threadedly connected to the limit bolt 63, and a No. 2 spring 62 is arranged between the boss 61 and the limit bolt 63.

[0057] In this embodiment, after placing the goods on the storage plate of the storage rack 12, the limiting bolt 63 is screwed, and the limiting bolt 63 pushes the second spring 62 to be compressed. At this time, the second spring 62 pushes the positioning seat 15 to increase the clamping force on the goods.

[0058] like Figure 6 As shown, a road cargo transport logistics box provided by the present invention is shown, wherein the adsorption mechanism 7 includes a sleeve 71, a sliding sleeve 72, a suction cup 73 and a one-way air outlet valve 74;

[0059] The sleeve 71 is fixedly connected to the inner top surface of the box body 1, and the sleeve 71 is slidably connected to a sliding sleeve 72. One end of the sliding sleeve 72 is slidably and sealedly connected to the inner wall of the sleeve 71. The end of the sliding sleeve 72 facing the door panel of the box body 1 is connected to a suction cup 73. The inner cavity of the sleeve 71 is connected to a one-way air outlet valve 74 for one-way air outlet to the outside, and the upper end of the column rod 14 is slidably and sealedly connected to the inner wall of the sleeve 71.

[0060] In this embodiment, when the door panel of the box body 1 is closed, the door panel fits with the suction cup 73, and the door panel pushes the sliding sleeve 72 to shrink into the sleeve 71. At this time, the air pressure in the sliding sleeve 72 increases, and the one-way air outlet valve 74 unidirectionally guides the exhaust to the outside, and the door panel is adsorbed by the suction cup 73, thereby increasing the connection stability between the door panel and the box body 1;

[0061] When the column 14 moves downward, one end of the column 14 slides in the sleeve 71. At this time, the air pressure in the sleeve 71 decreases. Under the action of the air pressure, the sliding sleeve 72 continues to move into the sliding sleeve 72, increasing the pulling force of the suction cup 73 on the door panel.

[0062] like Figure 3 As shown, a road cargo transport logistics box provided by the present invention, the hydraulic mechanism 8 includes a hydraulic box 81, a piston plate 82, a one-way water inlet valve 83, a water pipe 84 and a one-way water outlet valve 85;

[0063] The hydraulic box 81 is fixedly connected to the outer wall of the water tank 2, and the inner wall of the hydraulic box 81 is slidably and sealingly connected with a piston plate 82, and a connecting rod is connected between the piston plate 82 and the baffle 11. A one-way water inlet valve 83 that guides one-way flow into the hydraulic box 81 is connected between the hydraulic box 81 and the water tank 2, and a water pipe 84 is connected between the hydraulic box 81 and each water bag 16, and each water pipe 84 is provided with a one-way water outlet valve 85 that guides one-way flow into the water bag 16.

[0064] In this embodiment, when the baffle 11 is subjected to force, the baffle 11 drives the piston plate 82 to slide in the hydraulic box 81 through the connecting rod. At this time, the water pressure in the hydraulic box 81 increases, and the water flow in the hydraulic box 81 is transported to each water bag 16 through the water pipe 84;

[0065] Then, under the action of the resilience of the elastic telescopic rod 10, the baffle 11 drives the piston plate 82 to slide in the hydraulic box 81 in the opposite direction through the connecting rod, and the water in the water tank 2 flows to the hydraulic box 81 to replenish the water, so that the water flow can be continuously transported to the water bag 16, thereby increasing the vibration reduction effect of the water bag 16;

[0066] Since obstacles are generally closer to the bottom of the box body 1, the goods near the bottom of the box body 1 are likely to be subjected to a greater impact force first. By changing the intercepting area of ​​the one-way water outlet valve 85 on each water pipe 84, the filling speed of water into each water bag 16 can be adjusted, thereby adjusting the vibration resistance of goods on different heights of the shelf 12.

[0067] like Figure 4 As shown, a road cargo transport logistics box provided by the present invention, the transmission assembly 9 includes a push block 91, a guide block 92 and a latching tooth 93;

[0068] The lower end of the column rod 14 is fixedly connected to a guide block 92 , and the baffle 11 is fixedly connected to a push block 91 . The push block 91 and the guide block 92 have inclined surfaces that are arranged opposite to each other, and a plurality of latch teeth 93 are arranged on the inclined surfaces of the push block 91 and the guide block 92 .

[0069] In this embodiment, the baffle 11 drives the push block 91 to move horizontally, the push block 91 contacts and pushes the guide block 92, the guide block 92 drives the column 14 to move downward, the column 14 drives the positioning seat 15 to clamp the cargo, and the positioning seat 15 pushes the center of gravity of the cargo downward;

[0070] A plurality of latch teeth 93 are arranged on the inclined surfaces of the push block 91 and the guide block 92. When the baffle 11 is compressed and contracted, the guide block 92 can exert a certain limiting force on the push block 91 through the mutual engagement between the push block 91 and the guide block 92, so that the baffle 11 can slowly return to its original position after being hit, thereby preventing the elastic telescopic rod 10 from pushing the baffle 11 to rebound immediately and affecting the stability of the box body 1.

[0071] like Figure 2 As shown, a road freight transport logistics box provided by the present invention is provided with a sealing strip 17 at the door frame of the box body 1 , and the sealing strip 17 is connected to the inner cavity of the hydraulic box 81 .

[0072] In this embodiment, when the baffle 11 is under pressure, the baffle 11 pushes the piston plate 82 to slide in the hydraulic box 81. At this time, the water flow in the hydraulic box 81 enters the sealing strip 17 to increase the airtightness between the door panel and the box body 1, thereby preventing the door panel from being deformed by rigid collision when hit, thereby causing the suction cup 73 to detach from the door panel.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
