During the transportation process, a cargo protection device is required to prevent damage to the goods.
[0003] During the transportation of goods, especially during long-distance transportation, there are certain requirements on the degree of bumpiness of the transport carrier, especially for some items that cannot be excessively bumpy, such as precision instruments, chemical products, and flammable and explosive items. However, the current cargo support device has insufficient shock absorption effect, and thus the protection effect of the items is not high. Utility Model Content

When the vibration force is transmitted to the box body, the rubber plate can freely expand and contract in the direction of the corrugation. This characteristic enables it to effectively absorb and consume energy when subjected to the vibration force, thereby reducing the force transmitted to the main body of the cargo; the vibration force will cause the rubber plate to be subjected to horizontal force, and the vertical direction of the corrugation of the rubber plate can resist the horizontal force.

[0022] The following combination Figure 1-Figure 5 The utility model is described in further detail.
[0023] This embodiment discloses a shock absorbing device for cargo transportation: Figure 1-Figure 5 A shock absorbing device for cargo transportation includes a box body 10, a shock absorbing plate 20 and a plurality of buffer assemblies 30. The box body 10 is provided with a accommodating cavity 11, and the shock absorbing plate 20 is placed in the accommodating cavity 11; the shock absorbing plate 20 includes a bottom plate 21, a rubber plate 22 and a top plate 23. The bottom plate 21 is placed at the bottom of the accommodating cavity 11, and the rubber plate 22 is fixedly arranged between the bottom plate 21 and the top plate 23. The rubber plate 22 is composed of a plurality of first inclined plates 221 and second inclined plates 222, which are all inclined. The two ends of the first inclined plates 221 and the second inclined plates 222 are connected to each other. The rubber plate 22 is corrugated, and a plurality of sponge strips 24 for filling are equidistantly arranged on the rubber plate 22; the buffer assembly 30 is used to reduce shock to the box body 10.
[0024] When the device vibrates under the action of external force, the buffer assembly 30 can provide preliminary buffering and shock absorption for the vibration force transmitted to the box body 10. When the vibration force is transmitted to the box body 10, the rubber sheet 22 can freely expand and contract in the corrugation direction. This characteristic enables it to effectively absorb and consume energy when subjected to the vibration force, thereby reducing the force transmitted to the cargo body; the vibration force will cause the rubber sheet 22 to be subjected to horizontal force, and the vertical direction of the corrugation of the rubber sheet 22 can resist the horizontal force. This design makes the rubber sheet 22 have a certain stability in the horizontal direction, thereby increasing the seismic resistance of the structure; and, through the design of multiple first inclined plates 221 and second inclined plates 222 being interconnected, the rubber sheet 22 can consume energy through these first inclined plates 221 and second inclined plates 222 when subjected to external force, and further consume energy in conjunction with the sponge strips 24, thereby achieving a very good shock absorption effect; thereby improving the shock absorption protection effect of the article.
[0025] Reference Figure 2-Figure 5 The buffer assembly 30 includes a base 31, a shell 32, a piston block 33, a piston rod 34 and a top seat 35. The shell 32 is set on the base 31, and an oil tank 321 is provided in the shell 32. One end of the piston rod 34 is set on the top seat 35, and the other end seals through the shell 32 and extends into the oil tank 321 and is connected to the piston block 33. The piston block 33 is sealed and slidably connected in the oil tank 321, and a plurality of oil holes a331 are provided on the piston block 33.
[0026] When the device vibrates under the action of external force, the piston rod 34 and the piston block 33 are forced to move downward, which will cause a change in the liquid pressure inside the shell 32. The liquid pressure in the shell 32 changes, and the liquid flows through the oil hole a331 to adjust the oil pressure to reduce vibration, thereby further improving the shock absorption effect.
[0027] Reference Figure 5 The buffer assembly 30 further includes an elastic cover 36 , one end of which is disposed on the housing 32 , and the other end of which is disposed on the piston rod 34 .
[0028] When the piston rod 34 drives the piston block 33 to slide in the oil tank 321, the elastic cover 36 is compressed, and the elastic cover 36 wraps the piston rod 34 to prevent dust from entering the piston rod 34 and further entering the oil tank 321 to cause damage; and when there is no external force on the box body 10, the piston rod 34 will move upward under the elastic force of the elastic cover 36, facilitating the next shock absorption operation.
[0029] Reference Figure 5 A storage bin 322 is provided in the shell 32, and an oil hole b323 is provided at the bottom of the oil bin 321. The oil bin 321 is connected to the storage bin 322 through the oil hole.
[0030] When the device vibrates under the action of external force, the piston rod 34 and the piston block 33 are forced to move downward, which will cause a change in the liquid pressure inside the shell 32. The liquid pressure in the shell 32 changes, and the liquid flows through the oil hole a331 and the oil hole b323 to adjust the oil pressure to reduce vibration, thereby further improving the shock absorption effect. The storage bin 322 is used to store oil and adjust the oil pressure.
[0031] Reference Figures 1-4 The buffer assembly 30 also includes a first slide 37 and a second slide 38. The first slide 37 is set on the base 31, and the second slide 38 is set on the top seat 35. The second slide 38 is slidably installed on the first slide 37 by opening an arc-shaped slide groove 381.
[0032] When the device vibrates under the action of external force, the second slide plate 38 slides on the first slide plate 37 and is unlikely to shake, which is used to prevent the box body 10 from vibrating in the horizontal direction and affecting the shock absorption effect of the buffer assembly 30.
[0033] Reference Figure 4 The second slide plate 38 is provided with an anti-slip pad 382 , and the anti-slip pad 382 is in contact with the first slide plate 37 .
[0034] When the device vibrates under the action of external force, the second slide plate 38 slides on the first slide plate 37, and the anti-slip pad 382 forms a damping force between the first slide plate 37 and the second slide plate 38, thereby achieving a shock-absorbing effect.
[0035] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
