Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold chain transportation technology, specifically to an anti-collision structure for a refrigerated container and a refrigerated container. Background Technology
[0002] Refrigerated containers are crucial equipment in cold chain transportation. They utilize a refrigeration unit installed at the front of the container to supply cold air into the cargo space, maintaining a low temperature to meet transport requirements. Typically, the refrigeration unit's outlet is located at the top front of the container, while the return air vent is at the bottom. Specifically, a refrigeration unit mounting opening is located on the upper part of the front wall. To prevent collisions between cargo and the refrigeration unit, a crash barrier is usually installed on the inner side of the front wall to protect the refrigeration unit. The bottom of the crash barrier forms an opening with the upper surface of the floor, creating a return air vent for the refrigeration unit that extends from one side of the container to the other. When loading cargo into a refrigerated container, pallets are placed on the floor. During transport, these pallets may sway and collide with the bottom of the crash barrier, causing deformation and affecting the refrigeration unit's return air efficiency. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose an anti-collision structure for refrigerated containers to prevent deformation of the return air vent and ensure that the refrigeration unit has better return air efficiency.
[0004] The second objective of this utility model is to provide a refrigerated container.
[0005] To achieve the first objective mentioned above, this utility model adopts the following technical solution:
[0006] The anti-collision structure of refrigerated containers includes the container body, refrigeration unit, and anti-collision plates;
[0007] The front end of the enclosure is provided with a front wall, and a chiller installation port is provided on the front wall. The chiller is installed at the chiller installation port.
[0008] The anti-collision plate is connected to the inside of the front wall. The upper part of the anti-collision plate covers the inside of the chiller, and the lower part of the anti-collision plate covers the inside of the front wall. The chiller air outlet is formed above the upper edge of the anti-collision plate, and the chiller return air outlet is formed between the lower edge of the anti-collision plate and the upper surface of the floor of the cabinet. An installation part is formed at the bottom of the inner side of the front wall, directly opposite the chiller return air outlet.
[0009] Multiple anti-collision blocks are detachably installed on the mounting section, arranged along the extension direction of the chiller return air inlet, or multiple anti-collision blocks are slidably installed on the mounting section, arranged along the extension direction of the chiller return air inlet; the anti-collision blocks are located below the lower edge of the anti-collision plate.
[0010] The side of the anti-collision block away from the mounting part forms an anti-collision surface, and the distance of the anti-collision surface offset inward from the inner side of the anti-collision plate is 0~15mm.
[0011] The mounting part is a bracket fixed to the bottom of the inner side of the front wall. The bracket is plate-shaped and extends along the width of the box. Both ends of the bracket are fixedly connected to the front wall. The bracket is provided with multiple bolt holes arranged along the extension direction of the bracket. The anti-collision block is fixed to the bracket by fixing bolts passing through the bolt holes.
[0012] The bracket has a connecting end that bends toward the front wall at both ends. The connecting end is fixed to the front wall so that the bracket, except for the connecting end, forms a fitting gap with the front wall.
[0013] The anti-collision block has a groove recessed from the anti-collision surface toward the bracket, and the nut of the fixing bolt is embedded in the groove.
[0014] The crash barrier includes a fixed plate that is fixed to the front wall and a movable plate located below the fixed plate, with the top of the movable plate hinged to the bottom of the fixed plate.
[0015] Multiple support beams extending along the height direction are fixedly connected to the outer side of the movable panel. The support beams are supported on the inner side of the front wall to create a return air gap between the movable panel and the front wall.
[0016] To achieve the second objective mentioned above, this utility model adopts the following technical solution:
[0017] Refrigerated containers, including the aforementioned anti-collision structures for refrigerated containers.
[0018] The beneficial effects of this utility model are as follows:
[0019] In this invention, multiple anti-collision blocks are installed at the refrigeration unit return air vent formed between the anti-collision plate and the floor. When loading goods, the pallet at the frontmost point of the cargo space of the container is placed at the frontmost point of the floor. The anti-collision blocks block the frontmost pallet, preventing it from colliding with the lower edge of the anti-collision plate when it sways forward during transportation, thus protecting the anti-collision plate. In addition, the gaps between adjacent anti-collision blocks allow air in the cargo space of the container to flow back into the refrigeration unit. Since the anti-collision blocks are detachably fixed to the mounting part on the front wall, the appropriate number of anti-collision blocks can be set according to the size of the pallet.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:
[0025] like Figure 1 , 2 As shown in Figures 3 and 4, this utility model discloses an anti-collision structure for a refrigerated container, comprising a container body 10, a refrigeration unit 20, and an anti-collision plate 30. A front wall 11 is provided at the front end of the container body 10, with a refrigeration unit mounting port on its upper part. The refrigeration unit 20 is placed on the outside of the front wall 11 and installed at the refrigeration unit mounting port, such that both the outlet and inlet ends of the refrigeration unit 20 face the cargo space inside the container body 10. The anti-collision plate 30 is connected to the inner side of the front wall 11, wherein the upper part of the anti-collision plate 30 blocks the interior of the refrigeration unit 20. The side wall 30 protects the chiller 20. The lower part of the anti-collision plate 30 is shielded inside the front wall 11. The chiller air outlet is formed above the upper edge of the anti-collision plate 30. The chiller return air outlet is formed between the lower edge of the anti-collision plate 30 and the upper surface of the floor 12 of the housing 10. A mounting part is formed at the bottom of the inner side of the front wall 11, directly opposite the chiller return air outlet. Multiple anti-collision blocks 50 are detachably installed on the mounting part. The multiple anti-collision blocks 50 are arranged along the extension direction of the chiller return air outlet and are placed below the lower edge of the anti-collision plate 30.
[0026] In this invention, multiple anti-collision blocks 50 are installed at the refrigeration unit return air vent formed between the anti-collision plate 30 and the floor 12. When loading goods, the pallet at the frontmost end of the cargo space of the box 10 is placed at the frontmost end of the floor 12. The anti-collision blocks 50 block the frontmost pallet, preventing it from colliding with the lower edge of the anti-collision plate 30 when it sways forward during transportation. Thus, the anti-collision blocks 50 protect the anti-collision plate 30. In addition, the gap between adjacent anti-collision blocks 50 allows air in the cargo space of the box 10 to flow back into the refrigeration unit 20. Since the anti-collision blocks 50 are detachably fixed to the mounting part of the front wall 11, the number of anti-collision blocks 50 can be set according to the size of the pallet. For example, if the size of the pallet or goods is large, fewer anti-collision blocks 50 can be set, and if the size of the pallet or goods is small, more anti-collision blocks 50 can be set. In short, the distance between adjacent anti-collision blocks 50 is less than the size of the pallet or goods, so as to prevent the goods from moving forward.
[0027] In a preferred embodiment, the side of the anti-collision block 50 away from the mounting part of the front wall 11 forms an anti-collision surface 51. The anti-collision surface 51 is offset from the inner side of the anti-collision plate 30 towards the cargo space of the box 10 by a distance of 0~15mm. That is to say, the anti-collision surface 51 of the anti-collision block 50 protrudes inward from the inner side of the anti-collision plate 30 or is flush with the inner side of the anti-collision plate 30. The anti-collision surface 51 on the anti-collision block 50 is used to limit the pallet or goods at the foremost position.
[0028] The aforementioned mounting component is a bracket 40 fixed to the bottom of the inner side of the front wall 11. The bracket 40 is shaped and extends along the width direction of the housing 10. Both ends of the bracket 40 are fixedly connected to the bottom of the inner side of the front wall 11, so that the bracket 40 is positioned directly opposite the return air inlet of the chiller. The bracket 40 is provided with multiple bolt holes arranged along the extension direction of the bracket 40. The anti-collision blocks 50 are fixed to the bracket 40 by fixing bolts 53 passing through the bolt holes. During assembly, multiple anti-collision blocks 50 can be first fixed to the bracket 40 to form an assembly by fixing bolts 53, and then the assembly can be fixed to the front wall 11. The bracket 40 has a connecting end 41 bent towards the front wall 11 at each end. Both connecting ends 41 are fixed to the front wall 11, so that the other part of the bracket 40 except for the two connecting ends 41 forms a fitting gap with the inner side of the front wall 11. In this way, the bracket 40 forms a structure that can elastically deform in front and back. When the anti-collision block 50 is hit by a pallet or goods, the bracket 40 deforms forward to buffer the impact force of the pallet or goods on the anti-collision block 50 and avoid the anti-collision block 50 from loosening and falling off due to long-term and repeated rigid impacts.
[0029] The anti-collision block 50 is provided with a groove 52 that is recessed from the anti-collision surface 51 toward the bracket 40. The nut of the fixing bolt 53 is embedded in the groove 52. In this way, the fixing bolt 53 is prevented from protruding from the anti-collision surface 51, thus avoiding damage to the pallet or goods when the anti-collision surface 51 is receiving the pallet or goods.
[0030] In this invention, the anti-collision plate 30 includes a fixed plate 31 fixed to the front wall 11 and a movable plate 32 located below the fixed plate 31. The top of the movable plate 32 is hinged to the bottom of the fixed plate 31. The movable plate 32 can be flipped upwards to facilitate the clearing of the passage between the chiller return air inlet and the inlet end of the chiller 20. Multiple supporting vertical beams 33 extending along the height direction are fixedly connected to the outer side of the movable plate 32. The supporting vertical beams 33 support the inner side of the front wall 11, thereby forming a return air gap between the movable plate 32 and the front wall 11, through which the chiller return air inlet and the inlet end of the chiller 20 are connected. Simultaneously, the supporting vertical beams 33 also increase the strength of the movable plate 32 to effectively prevent deformation of the movable plate 32 when impacted by goods.
[0031] In another embodiment, the present invention may also involve slidingly mounting multiple anti-collision blocks arranged along the extension direction of the refrigeration unit's return air inlet on the mounting part. For example, a sliding guide rail may be provided on the bracket 40, and multiple anti-collision blocks may be slidably mounted on the sliding guide rail. The multiple anti-collision blocks may be moved to the corresponding positions according to the size of the pallet and the goods, so that the interval between adjacent anti-collision blocks is less than the size of the pallet or the goods.
[0032] The refrigerated container of this utility model includes the anti-collision structure of the refrigerated container mentioned above. Other structures of the refrigerated container are the same as those in the prior art and will not be described in detail here.
[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
