Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a buffer device for container transportation. Background Technology

[0002] A shipping container is a standardized transport container designed to facilitate the loading, handling, transport, and storage of goods. It is typically made of robust metal and has fixed dimensions, allowing for rapid transfer between different modes of transport such as ships, trains, and trucks, and effectively protecting goods from weather and physical damage.

[0003] Existing container structures are simple and designed solely for storing goods, lacking necessary cushioning measures. As a result, containers are prone to swaying under the influence of waves during container ship transportation operations. Since there are gaps between the goods inside the container, the swaying can cause the goods inside to collide with each other, thereby damaging the goods and significantly increasing costs.

[0004] Therefore, it is necessary to design a buffer device for container transportation. Utility Model Content

[0005] In order to overcome the shortcomings of existing container structures, such as simple design, lack of necessary cushioning measures, and easy shaking of containers, which can cause damage to the internal cargo, the technical problem to be solved is to provide a cushioning device for container transportation.

[0006] The technical solution of this utility model is: a buffer device for container transportation, including a container body, a container door, an air pump, an air supply pipe, a mounting frame, an inflatable bag, a hose, and a drive mechanism. The container door is rotatably connected to the opening of the container body. A drive mechanism is provided inside the container body. The drive mechanism is connected to the mounting frame. An inflatable bag is installed on the mounting frame. An air pump is installed inside the container body. The output end of the air pump is connected to the air supply pipe. The air supply pipe is connected to the inflatable bag through a hose.

[0007] To further explain, a fixing plate is fixedly connected inside the box. The fixing plate is located above the drive mechanism, and one end of the mounting frame and the inflation bag both pass through the fixing plate.

[0008] To further explain, a backing plate is installed on the inner wall of the box, and a buffer spring is installed between the box and the backing plate, with both ends of the buffer spring connected to the box and the backing plate respectively.

[0009] To further explain, the drive mechanism includes a rotating shaft, a motor, a screw, and a gear set. The rotating shaft and the screw are rotatably connected inside the housing, and a gear set is provided between the screw and the rotating shaft. The motor is installed inside the housing, and the output shaft of the motor is connected to the rotating shaft.

[0010] To further explain, the gear set consists of two meshing bevel gears, and the two bevel gears are fixedly connected to the rotating shaft and the screw, respectively. When the rotating shaft rotates, it drives the screw to rotate through the gear set.

[0011] To further explain, there are no fewer than three air bags, and the air bags can be inflated after the air pump delivers air.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention fills the gap between goods by inflating the air bag, effectively separating and fixing the goods on both sides, preventing the goods from colliding with each other due to the shaking of the box during transportation, thereby protecting the integrity and safety of the goods.

[0013] 2. This utility model, through motor drive, gear transmission and screw moving mechanism, can easily adjust the position of the inflatable bag to adapt to goods of different shapes, sizes and placement forms, thus improving the versatility and flexibility of the device.

[0014] 3. The present invention provides additional cushioning when the device shakes due to the setting of the buffer spring, thereby further enhancing the stability of the goods during transportation and reducing the risk of damage to the goods. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: A buffer device for container transportation, such as Figures 1-4 As shown, the device includes a housing 1, a door 2, an air pump 8, an air supply pipe 81, a mounting frame 10, an inflatable bag 11, a hose 12, and a drive mechanism. The door 2 is rotatably connected to the opening of the housing 1. The drive mechanism is installed inside the housing 1 and connected to the mounting frame 10. An inflatable bag 11 is installed on the mounting frame 10. The air pump 8 is installed inside the housing 1, and the output end of the air pump 8 is connected to the air supply pipe 81. The air supply pipe 81 is connected to the inflatable bag 11 through the hose 12. Here, there are no fewer than three inflatable bags 11. After the air pump 8 supplies air, the inflatable bags 11 can expand, effectively improving the protective performance of the device.

[0022] like Figures 3-4 As shown, a fixing plate 3 is fixedly connected inside the box 1. The fixing plate 3 is located above the drive mechanism. One end of the mounting frame 10 and the air bag 11 both pass through the fixing plate 3. Here, the design of the fixing plate 3 can cover the rotating shaft 6, motor 7, air pump 8 and air supply pipe 81 and other components, so as to reduce the contact between the goods and components during the subsequent loading process and effectively protect the safety of the goods and components.

[0023] like Figure 2 As shown, a backing plate 4 is provided on the inner wall of the box 1, and a buffer spring 5 is provided between the box 1 and the backing plate 4. The two ends of the buffer spring 5 are connected to the box 1 and the backing plate 4 respectively. Here, when the device shakes, the buffer spring 5 can provide cushioning for the goods inside the box 1 by relying on its own deformation and recovery action, thereby further improving the stability of the goods.

[0024] like Figure 4 As shown, the drive mechanism includes a rotating shaft 6, a motor 7, a screw 9, and a gear set 91. The rotating shaft 6 and the screw 9 are rotatably connected inside the housing 1. The gear set 91 is arranged between the screw 9 and the rotating shaft 6. The motor 7 is installed inside the housing 1. The output shaft of the motor 7 is connected to the rotating shaft 6. The gear set 91 consists of two meshing bevel gears, which are fixedly connected to the rotating shaft 6 and the screw 9, respectively. When the rotating shaft 6 rotates, it drives the screw 9 to rotate through the gear set 91. Here, when the motor 7 is started, the motor 7 drives the output shaft to rotate. The output shaft of the motor 7 drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the screw 9 to rotate through the gear set 91, so that the mounting frame 10 moves horizontally with the rotation of the screw 9. This allows the position of the inflatable bag 11 to be adjusted to adapt to different cargo placement methods, effectively improving the flexibility and adaptability of the device.

[0025] This device provides cushioning protection for goods during container transport operations. In use, the goods are placed on the side of the container 1 away from the inflatable bag 11. After the goods have accumulated on the side of the container 1 away from the inflatable bag 11, the motor 7 is started. The motor 7 drives the output shaft to rotate, which in turn drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the screw 9 to rotate via the gear set 91, thereby causing the mounting frame 10 to move horizontally under the drive of the screw 9. The mounting frame 10 then moves the inflatable bag 11 towards the center of the container 1, and then continues towards the center of the container 1. The goods are stacked inside, ensuring that there is enough cargo on both sides of the container 1. Then, the air pump 8 is started, and the air pump 8 injects air into the air supply pipe 81. Then, the air supply pipe 81 delivers the air to the air bag 11 through the hose 12. After receiving the air, the air bag 11 expands and fills the gap between the goods on both sides, thereby separating the goods on both sides and providing a certain cushion for the goods to prevent the goods from colliding when the container 1 shakes later. Then, the container door 2 is turned to close the container 1.

[0026] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation in order to cover all variations and equivalent structures and functions.
