Description

Technical Field

[0001] This utility model relates to the field of buffer device technology, and in particular to a cargo transport device with a double-layer buffer structure. Background Technology

[0002] In cargo transportation scenarios, especially when using box trucks, goods often experience significant inertial impact due to sudden stops, bumps, or accidental collisions.

[0003] The existing buffer structures of transportation devices are mostly single springs or simple rubber pads, which have defects such as few buffer layers, poor force distribution, and low buffer limit. This results in a high rate of cargo damage, which not only increases transportation costs but also easily leads to cargo damage disputes.

[0004] Therefore, a cargo transport device with a double-layer buffer structure is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a cargo transportation device with a double-layer buffer structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cargo transport device with a double-layer buffer structure includes a buffer shell installed inside the cargo compartment. The buffer shell is hollow with an open top, and one side serves as a buffer-bearing surface. It does not have a panel. The device also includes:

[0008] The extrusion plate is slidably connected within the buffer bearing surface of the buffer shell to absorb and guide the impact force generated by the cargo in the carriage during sudden stops.

[0009] A buffer wave plate is installed inside the buffer shell. When the buffer wave plate is impacted by the extrusion plate, the wave plate disperses and absorbs the impact force through corrugated elastic deformation. After the external force disappears, it quickly rebounds and resets, thus completing the buffering.

[0010] Multiple sets of hollow rubber balls are hollowly arranged and filled inside the buffer shell, and are attached to the buffer corrugated plate. When the hollow rubber balls are impacted by the extrusion plate, the hollow rubber balls are squeezed and deformed, the internal air is compressed and the pore structure shrinks, thereby absorbing and dispersing the impact force. After the external force disappears, the balls return to their original shape by relying on the elasticity of the rubber and the rebound of the internal air, thus completing the buffering.

[0011] Preferably, the top of the buffer shell is detachably fitted with an inspection cover.

[0012] Preferably, multiple sets of buffer springs are installed on the extrusion plate, and the other end of the buffer spring is connected to the buffer shell.

[0013] Preferably, a bellows is fitted onto the buffer spring.

[0014] Preferably, both ends of the buffer wave plate are far away from the sidewall of the buffer shell.

[0015] Preferably, an external receiving plate is fixedly connected to the extrusion plate, and the external receiving plate is used to absorb the impact force generated by the goods.

[0016] Preferably, a top plate is provided between the buffer corrugated plate and the extrusion plate.

[0017] Preferably, a limiting plate is fixedly connected to the buffer shell on the buffer bearing surface to restrict the movement of the extrusion plate and prevent it from moving out of the buffer shell.

[0018] Compared with the prior art, this utility model provides a cargo transportation device with a double-layer buffer structure, which has the following beneficial effects:

[0019] This invention utilizes the synergistic effect of a buffer wave plate and a buffer rubber porous ball to form a double-layer buffer structure that combines elastic deformation and structural deformation. This structure can efficiently disperse and absorb the impact force during cargo transportation, significantly reducing the risk of damage to cargo caused by sudden stops or collisions.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example: Refer to Figure 1-5 A cargo transport device with a double-layer buffer structure includes a buffer shell 1, which is installed inside the cargo compartment. The buffer shell 1 is hollow with an open top, and one side is a buffer receiving surface without a panel. It also includes: a compression plate 2, which is slidably connected to the buffer receiving surface of the buffer shell 1 to receive and guide the impact force generated by the cargo in the cargo compartment during sudden stops; a buffer corrugated plate 5, which is installed inside the buffer shell 1. When the buffer corrugated plate 5 is impacted by the compression plate 2, the corrugated plate disperses and absorbs the impact force through corrugated elastic deformation. After the external force disappears, it quickly rebounds and resets, thus completing the buffering; and multiple sets of hollow rubber balls 9, which are hollow and fill the buffer shell 1 and are attached to the buffer corrugated plate 5. When the hollow rubber balls 9 are impacted by the compression plate 2, the hollow rubber balls are squeezed and deformed, the internal air is compressed, and the pore structure contracts, thereby absorbing and dispersing the impact force. After the external force disappears, the balls return to their original shape due to the elasticity of the rubber and the rebound of the internal air, thus completing the buffering.

[0028] The top of the buffer shell 1 is detachably fitted with an inspection cover 4.

[0029] Multiple sets of buffer springs 6 are installed on the extrusion plate 2, and the other end of the buffer spring 6 is connected to the buffer shell 1.

[0030] A bellows 7 is fitted onto the buffer spring 6.

[0031] Both ends of the buffer wave plate 5 are far away from the side wall of the buffer shell 1.

[0032] An external support plate 3 is fixedly connected to the extrusion plate 2. The external support plate 3 is used to absorb the impact force generated by the goods.

[0033] A top plate 8 is provided between the buffer corrugated plate 5 and the extrusion plate 2.

[0034] A limiting plate 101 is fixedly connected to the buffer housing 1 on the buffer bearing surface to restrict the movement of the compression plate 2 and prevent it from being removed from the buffer housing 1.

[0035] When the carriage comes to an abrupt stop, the cargo will shift, generating an impact force. At this time, as long as the cargo is in contact with the external support plate 3, the impact will first act on the external support plate 3 and the compression plate 2. The compression plate 2 compresses the buffer spring 6 (the bellows 7 deforms synchronously to prevent the hollow ball from entering between the springs and affecting the spring's contraction and reset). The initial buffering is achieved through the elastic deformation of the spring. At the same time, part of the impact force is transmitted to the buffer rubber hollow ball 9. The hollow ball is squeezed and deformed, and the remaining impact force is absorbed through the elasticity of the rubber and the compression of the internal air.

[0036] The remaining impact force is transmitted to the buffer wave plate 5 through the top plate 8. Its corrugated structure undergoes elastic deformation, which disperses and absorbs the impact force (secondary buffering). While the wave plate deforms, the remaining buffer rubber hollow ball 9 absorbs and buffers the impact force again.

[0037] After the external force disappears, each component returns to its original position by its own elasticity or by the rebound of internal air, thereby efficiently dispersing and absorbing the impact force of the cargo and ensuring the safety of cargo transportation.

[0038] Specifically, this device can also be installed on the side wall of the carriage.

[0039] This utility model forms a double-layer buffer structure with both elastic deformation and structural deformation through the synergistic effect of the buffer wave plate 5 and the buffer rubber hollow ball 9. It can efficiently disperse and absorb the impact force during the transportation of goods, and greatly reduce the risk of damage to goods caused by sudden stops and collisions.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
