Technical Field
[0001] This utility model belongs to the field of container technology, specifically, it relates to a refrigerated container holding rack with strong load-bearing capacity. Background Technology
[0002] In the refrigerated container shipping industry, container cages are core components ensuring the stable storage and safe transport of goods. Existing refrigerated container cages mostly use single-sheet panels or simple frame structures. When bearing heavy loads, these are prone to localized stress concentration, leading to cage deformation or even damage, affecting cargo stability. Simultaneously, the impact of bumps and jolting during transport is directly transmitted to the cargo, easily causing collision damage, especially for fragile and easily damaged refrigerated goods. Furthermore, some cages lack effective cushioning and positioning structures, making them prone to displacement during transport, further increasing the risk of cargo damage and failing to meet the high demands of refrigerated transport. Utility Model Content
[0003] The purpose of this invention is to provide a refrigerated container holding rack with high load-bearing capacity to solve the problems mentioned in the background art.
[0004] A high-load-bearing refrigerated container retainer includes a container, a door, a frame, and a retainer. The retainer comprises a load-bearing plate, reinforcing ribs, a mounting groove, a mounting plate, a base plate, and an airbag. The reinforcing ribs are fixedly connected to the bottom of the load-bearing plate. The mounting groove is located on the side of the load-bearing plate. The mounting plate is detachably connected to the load-bearing plate via the mounting groove. The base plate is positioned below the load-bearing plate, and the airbag is installed between the base plate and the load-bearing plate.
[0005] In a preferred embodiment of this utility model, the mounting plate is provided with a metal box, a positioning hole and a positioning container. The metal box is fixed to the surface of the mounting plate, the positioning hole is opened through one side of the metal box, and the positioning container is arranged adjacent to the metal box, and a desiccant is placed inside the positioning container.
[0006] In a preferred embodiment of the present invention, the retainer further includes a heat dissipation box, which is fixed to the side of the mounting plate away from the metal box. A cooling fan and a metal heat sink are installed inside the heat dissipation box, and the cooling fan and the metal heat sink are arranged correspondingly.
[0007] In a preferred embodiment of this utility model, ventilation holes are provided on both the load-bearing plate and the base plate. The ventilation holes are evenly distributed and connected to the interior of the heat dissipation box.
[0008] In a preferred embodiment of the present invention, the keel inside the container is fitted to the mounting plate of the retainer, and the surface of the keel is provided with positioning protrusions that are adapted to the positioning holes.
[0009] In a preferred embodiment of the present invention, a rubber pad is provided at the contact position between the bottom of the container and the bottom plate, and the rubber pad is in close contact with the bottom plate.
[0010] In a preferred embodiment of this utility model, the metal heat sink is made of aluminum alloy and has heat dissipation texture on its surface, and the cooling fan is electrically connected to an external power source.
[0011] Compared with the prior art, the present invention has the following advantages: 1.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0017] Example 1: Suitable for conventional refrigerated transportation scenarios, meeting basic load-bearing capacity and heat dissipation requirements.
[0018] like Figures 1 to 7 As shown, a high-load-bearing refrigerated container retainer includes a container 1, a door 2, a frame 3, and a retainer 5. The retainer 5 includes a load-bearing plate 501, a reinforcing rib 502, a mounting groove 503, a mounting plate 504, a bottom plate 509, and an airbag 510. The reinforcing rib 502 is fixedly connected to the bottom of the load-bearing plate 501. The mounting groove 503 is opened on the side of the load-bearing plate 501. The mounting plate 504 is detachably connected to the load-bearing plate 501 through the mounting groove 503. The bottom plate 509 is located below the load-bearing plate 501. The airbag 510 is installed between the bottom plate 509 and the load-bearing plate 501.
[0019] The retainer 5 also includes a heat sink 506, which is fixed to the side of the mounting plate 504 away from the metal box 5041. The heat sink 506 is equipped with a cooling fan 505 and a metal heat sink 507, with the cooling fan 505 and the metal heat sink 507 being arranged correspondingly.
[0020] Ventilation holes 508 are provided on both the load-bearing plate 501 and the base plate 509. The ventilation holes 508 are evenly distributed and connected to the interior of the heat dissipation box 506. The keel 3 inside the container 1 is fitted to the mounting plate 504 of the retainer 5. The surface of the keel 3 is provided with positioning protrusions that are compatible with the positioning holes 5042. A rubber pad 4 is provided at the contact position between the bottom of the container 1 and the base plate 509. The rubber pad 4 is tightly fitted to the base plate 509. The metal heat sink 507 is made of aluminum alloy and has heat dissipation texture on its surface. The cooling fan 505 is electrically connected to an external power supply.
[0021] Example 2: Suitable for high-humidity transportation environments, it can effectively absorb moisture inside container 1 and prevent goods from getting damp. Based on embodiment one, the mounting plate 504 is provided with a metal box 5041, a positioning hole 5042 and a positioning box 5043. The metal box 5041 is fixed to the surface of the mounting plate 504, the positioning hole 5042 is opened through one side of the metal box 5041, and the positioning box 5043 is arranged adjacent to the metal box 5041, and a desiccant 5044 is placed inside the positioning box 5043.
[0022] The load-bearing plate 501 and the base plate 509 are made of high-strength stainless steel with a thickness of 12mm to ensure the foundation's load-bearing capacity. The reinforcing ribs 502 are made of hot-rolled steel with an I-shaped cross-section and are fixed to the bottom of the load-bearing plate 501 by welding. The spacing is controlled at 200mm to distribute the pressure evenly.
[0023] Mounting plate 504 is made of aluminum alloy to reduce overall weight. Mounting grooves 503 are formed on both sides of load-bearing plate 501, and the groove width is adapted to the thickness of mounting plate 504. A detachable connection is achieved using bolts. Metal box 5041 and positioning box 5043 are formed by stamping and welded to the surface of mounting plate 504. Positioning hole 5042 has a diameter of 15mm and is interference-fitted with the positioning protrusion on the surface of keel 3.
[0024] The heat sink 506 is a sheet metal stamping part. The internal cooling fan 505 has a power of 50W. The metal heat sink 507 is made of 6063 aluminum alloy, and the surface is anodized to form heat dissipation patterns, increasing the heat dissipation area. The positioning box 5043 contains granular silica gel desiccant 5044.
[0025] The airbag 510 is made of nitrile rubber, with an inflation pressure set at 0.3 MPa, and is fixed between the load-bearing plate 501 and the bottom plate 509 by clips. The rubber pad 4 is 10 mm thick, made of natural rubber, and is attached to the bottom of the container 1 at the contact point with the bottom plate 509.
[0026] First, weld the reinforcing rib 502 to the bottom of the load-bearing plate 501. After completion, drill ventilation holes 508 with a diameter of 8mm on the load-bearing plate 501 and the base plate 509, with a hole spacing of 100mm and a matrix distribution. Fix the airbag 510 to the upper surface of the base plate 509, then align the base plate 509 with the load-bearing plate 501 and fix it with connectors to ensure that the airbag 510 is in the center between the two. Connect the mounting plate 504 to the load-bearing plate 501 through the mounting groove 503 and tighten the bolts on both sides. Then weld the metal box 5041 and the positioning box 5043 to the mounting plate 504. Position the container 5043, place a desiccant 5044 inside and seal it; fix the heat sink 506 on the other side of the mounting plate 504, and install the metal heat sink 507 and the cooling fan 505 inside in sequence, ensuring that the distance between the cooling fan 505 and the metal heat sink 507 is 50mm, and that the ventilation hole 508 is connected to the inside of the heat sink 506; finally, place the assembled retainer 5 inside the container 1, so that the mounting plate 504 fits against the keel 3, and achieve positioning by cooperating with the positioning protrusion through the positioning hole 5042; attach the rubber pad 4 to the bottom of the container 1 to complete the overall installation.
[0027] The connection between the base plate 509 and the load-bearing plate 501 uses high-strength nylon clips. The clips must withstand a tensile force of at least 500N. During installation, ensure the clips are fully engaged without any looseness or gaps. After placing the desiccant 5044 into the positioning box 5043, seal the box opening with butyl rubber sealing tape, then tighten it with a stainless steel pressure strip to ensure a sealed box and prevent moisture ingress or desiccant leakage. At the connection between the heat dissipation box 506 and the mounting plate 504, apply neutral silicone sealant with a thickness of 2-3mm, covering the entire connection surface to prevent airflow leakage from affecting heat dissipation.
[0028] This retainer is suitable for 20-foot and 40-foot standard refrigerated containers. The spacing between the internal keel 3 of container 1 must be 600mm or 1200mm. If the spacing between keel 3 is different, a mounting plate 504 of the corresponding length can be used for adaptation. The power cable for the cooling fan 505 is RVV2×1.5mm. 2 Flame-retardant cables are used, with cable conduit protection and waterproof terminals at the connection points to prevent short circuits caused by condensation. The positioning box 5043 has a transparent observation window on its side, allowing direct observation of the desiccant 5044's status. When the desiccant changes color from blue to pink, it must be replaced promptly, with a replacement cycle not exceeding 3 months.
[0029] Working principle: The goods are placed on the load-bearing plate 501, and the weight is transferred to the bottom reinforcing rib 502 through the load-bearing plate 501. The I-shaped reinforcing rib 502 disperses the pressure and prevents the load-bearing plate 501 from deforming due to excessive local stress. The airbag 510 between the load-bearing plate 501 and the bottom plate 509 absorbs the impact force through elastic deformation, especially during the bumpy transportation process, and plays a buffering role to reduce the collision damage between the goods and the cage 5. The rubber pad 4 at the bottom of the container 1 further enhances the buffering effect and increases the friction between the bottom plate 509 and the container 1 to prevent the cage 5 from shifting during transportation.
[0030] When the refrigerated container is in operation, the cooling fan 505 inside the heat dissipation box 506 is connected to an external power source and starts to generate airflow. The airflow enters the cage 5 through the ventilation holes 508 on the load-bearing plate 501 and the bottom plate 509, carrying away the heat dissipated by the cargo. After being cooled by the metal heat sink 507, it is discharged. The aluminum alloy metal heat sink 507 and the heat dissipation texture on its surface increase the heat exchange area, improve heat dissipation efficiency, and ensure that the internal temperature of the container 1 is stable.
[0031] The cage 5 is precisely positioned by engaging with the positioning protrusion of the keel 3 through the positioning hole 5042 on the mounting plate 504, thus preventing the cage 5 from shaking or shifting during transportation. The desiccant 5044 inside the positioning box 5043 continuously absorbs moisture inside the container 1, reducing air humidity and preventing the goods from getting damp and deteriorating, while also protecting the metal parts of the cage 5 from corrosion.
