[0022] 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.
[0023] Please see Figure 1-5 This utility model provides a technical solution: a detachable refrigerated container device, including a container panel 1, a door 2 installed on the surface of the container panel 1, a column 3 installed on the side of the container panel 1, a support rod 4 installed on the side of the container panel 1, an installation component 5 provided on the surface of the column 3 and the support rod 4, and a refrigeration device 6 provided on the surface of the container panel 1.
[0024] Mounting assembly 5 includes a connecting plate 501, which is fixedly connected to the surface of the column 3. Both the connecting plate 501 and the supporting side rod 4 have threaded holes 502 on their surfaces. The connecting plate 501 has a stop groove 503 on its surface. A screw 504 is threaded into the internal thread of the threaded hole 502. A connecting rod 505 is connected to the outer end of the screw 504. A nut 506 is connected to one end of the connecting rod 505. A sliding groove 507 is provided on the surface of the connecting rod 505. A stop ratchet 508 is slidably connected to the surface of the connecting rod 505. A slider 509 is connected to the inner side of the slide 507. A telescopic groove 510 is opened on the inner side of the slider 509. A spring 511 is connected to the inner end of the telescopic groove 510. A limit plate 512 is connected to the outer end of the spring 511. A positioning block 513 is connected to the outer end of the limit plate 512. A positioning hole 514 is opened on the inner side of the slide 507. Through the setting of the installation component 5, during installation, the screw 504 is first screwed into the threaded hole 502 to achieve the initial connection between the column 3, the support side rod 4 and the container plate 1. Then, the stop ratchet 508 is slid inward to make it slide along the connecting rod 5 The slide groove 507 on the surface of the 05 moves until it is engaged in the stop groove 503 on the surface of the connecting plate 501. During this process, the slider 509 slides synchronously in the slide groove 507. When the stop ratchet 508 is fully engaged in the stop groove 503, the elastic force generated by the deformation of the spring 511 pushes the limiting plate 512, causing the positioning block 513 to pop out from the telescopic groove 510 and engage in the positioning hole 514, forming a double locking structure: the engagement of the stop ratchet 508 and the stop groove 503 prevents the screw 504 from rotating axially, and the engagement of the positioning block 513 and the positioning hole 514 prevents the screw from rotating axially. To prevent the stop ratchet 508 from slipping out accidentally and ensure a secure connection, during disassembly, a large external force is applied to pull the stop ratchet 508. The positioning block 513 is compressed and overcomes the resistance of the spring 511 to retract into the telescopic groove 510, disengaging from the positioning hole 514 and releasing the lock. At this time, the stop ratchet 508 can slide outward along the slide groove 507 and disengage from the stop groove 503. Then, the nut 506 is rotated in the opposite direction to unscrew the screw 504, thus completing the disassembly of the component. This achieves a balance between rapid assembly and reliable fixation, significantly improving the convenience and structural stability of container disassembly.
[0025] Furthermore, the position of the stop ratchet 508 corresponds to the position of the stop groove 503, and the outer wall size of the stop ratchet 508 matches the inner wall size of the stop groove 503. Through the setting of the stop groove 503 and the stop ratchet 508, the precisely matched structure of the two forms a reliable mechanical stop mechanism. When the stop ratchet 508 is engaged in the stop groove 503, it can effectively prevent the screw 504 from rotating in the opposite direction, prevent the connection from loosening due to transportation vibration or external impact, and significantly improve the structural stability of the container after assembly. At the same time, the precise corresponding position design ensures that the operator can quickly position and lock during the installation process, improving the assembly efficiency.
[0026] Furthermore, the stop ratchet 508 slides on the surface of the connecting rod 505 via the slider 509 and the groove 507. The size of the slider 509 and the size of the groove 507 are matched. The groove 507 and the slider 509 provide a precise sliding track for the stop ratchet 508, allowing it to move smoothly along a predetermined path without deviation or jamming. The matching size design ensures that the slider 509 maintains a tight fit without excessive friction when sliding in the groove 507, ensuring smooth locking and unlocking operations. It also enhances the anti-shaking ability of the stop ratchet 508 and further improves the reliability of the connection.
[0027] Furthermore, the limiting plate 512 forms a telescopic structure through the cooperation of the spring 511 and the positioning block 513. The size of the positioning block 513 is precisely matched with the size of the positioning hole 514. Through the setting of the positioning block 513 and the positioning hole 514, the spring 511 drives the positioning block 513 and the positioning hole 514 to form an elastic locking structure, which can achieve quick and firm positioning and locking without additional tools. The precisely matched size ensures the accuracy of positioning. When disassembling, the spring force must be overcome to make the positioning block 513 disengage from the positioning hole 514, which effectively prevents accidental unlocking caused by misoperation. While ensuring convenient disassembly, it also ensures safety and stability during use, which is especially suitable for the needs of frequent loading and unloading in cold chain transportation.
[0028] Furthermore, the refrigeration unit 6 includes a refrigeration unit 601, which is installed on the outer top of the container panel 1. A cold air pipe 602 is connected above the refrigeration unit 601, and a corrugated hose 603 is connected to the other end of the cold air pipe 602. A motor 604 is connected to the inner side of the container panel 1, and a lead screw 605 is connected to the output end of the motor 604. A guide rod 606 is connected to the inner side of the container panel 1. Sliding sleeves 607 are slidably connected to the surfaces of both the lead screw 605 and the guide rod 606. An inner connecting plate 608 is connected to the inner side of the sliding sleeve 607. A connecting conduit 609 is connected to the surface of the device. A guide rod 610 is connected to the outside of the connecting conduit 609. A cold air guide 611 is connected to the surface of the guide rod 610. An upper connecting pipe 612 is connected above the cold air guide 611. An air outlet 613 is opened on the surface of the upper connecting pipe 612. An air outlet pipe 614 is connected to the bottom of the cold air guide 611. Through the configuration of the refrigeration device 6, when the refrigeration device 6 is started, the refrigeration unit 601 starts to operate and generates cold air. The cold air is delivered to the corrugated hose 603 through the cold air pipe 602. The bendability of the corrugated hose 603 ensures... To ensure unobstructed cold air delivery during the movement of the sliding sleeve 607, the motor 604 drives the lead screw 605 to rotate. Since the sliding sleeve 607 is threadedly connected to the lead screw 605 and slidably connected to the guide rod 606, the rotation of the lead screw 605 causes the sliding sleeve 607 to move linearly along the lead screw 605 and guide rod 606. The movement of the sliding sleeve 607 synchronously drives the connecting conduit 609, the guide rod 610, the cold air guide frame 611, the upper connecting pipe 612, and the air outlet pipe 614 to move via the inner connecting plate 608. This causes the cold air guide frame 611 to reciprocate inside the container, and the cold air is delivered through the connecting conduit... Pipe 609 enters the guide rod 610, and then flows to the upper connecting pipe 612 above the cold air guide 611 and the air outlet pipe 614 at the bottom. The air outlet 613 on the surface of the upper connecting pipe 612 releases cold air evenly into the upper space of the container, while the air outlet pipe 614 guides the cold air to the bottom area of the container. Through the movement of the cold air guide 611, the cold air is circulated and transported in all directions and at multiple angles in the container, avoiding temperature dead zones, ensuring that the internal temperature of the container is uniform and quickly reaches and maintains the set low temperature environment, effectively meeting the storage needs of cold chain goods.
[0029] Furthermore, the sliding sleeve 607 drives the inner connecting plate 608 to move via the lead screw 605 and guide rod 606. The bottom end of the corrugated hose 603 is connected to the top end of the connecting conduit 609. Through the arrangement of the corrugated hose 603, lead screw 605, guide rod 606, and connecting conduit 609, the flexible characteristic of the corrugated hose 603 combined with the linear drive structure of the lead screw 605 and guide rod 606 enables the sliding sleeve 607 to drive the connecting conduit 609 to move smoothly. This ensures that the piping connection of the refrigeration system is not affected when adjusting the position of the cold air delivery, maintaining the continuity and stability of the cold air delivery. At the same time, the guide rod 606 provides precise guidance for the sliding sleeve 607, preventing radial offset when the lead screw 605 rotates, ensuring the reliability of the entire refrigeration unit 6 and extending the service life of the equipment.
[0030] Furthermore, multiple sets of the upper connecting pipe 612 are arranged above the cold air guide 611, and multiple sets of air outlet holes 613 are opened on the surface of the upper connecting pipe 612. Multiple sets of air outlet pipes 614 are arranged at the bottom of the cold air guide 611. Through the arrangement of the upper connecting pipe 612, air outlet holes 613, and air outlet pipes 614, the multiple sets of upper connecting pipes 612 and the densely distributed air outlet holes 613 and multiple sets of air outlet pipes 614 work together to form a three-dimensional cold air diffusion network. The upper connecting pipe 612 evenly releases cold air into the upper space of the container, while the air outlet pipes 614 deliver cold air to the bottom area, achieving all-round coverage of cold air in the container, effectively eliminating temperature dead zones, significantly improving refrigeration efficiency and temperature uniformity, ensuring that cold chain goods are always in a suitable low-temperature environment, and reducing the risk of quality degradation of goods due to temperature fluctuations.
[0031] Working principle: The operator first connects the container panel 1 to the column 3 and support side rod 4 via the installation component 5. Initial fixation is achieved by screwing the screw 504 into the threaded hole 502. Then, the stop ratchet 508 is engaged with the stop groove 503 and locked by the positioning block 513, forming a stable frame structure. This process requires no welding or complex tools, allowing for rapid assembly. The modular design allows for flexible adjustment of the frame size according to the cargo dimensions. After loading the cargo and closing the container door 2, the refrigeration unit 6 is activated. The cold air generated by the refrigeration unit 601 is delivered to the connecting conduit 609 through the cold air pipe 602 and corrugated hose 603, and then distributed to the upper connecting pipe 612 and the outlet pipe 614 via the guide rod 610. At this time, the motor 604 drives the lead screw 605 to rotate, causing the sliding sleeve 607 to reciprocate along the guide rod 606, so that the cold air guide frame 611 evenly distributes the cold air inside the container. Multiple sets of upper connecting pipes 612 and outlet pipes... The three-dimensional airflow network formed by the air pipes 614 ensures that the temperature inside the container fluctuates within ±0.5℃, meeting the precise temperature control requirements of pharmaceuticals, fresh produce, and other products. Under bumpy road conditions, the double-locking structure of the mounting component 5 can resist vibration and remain secure. The flexible connection of the corrugated hose 603 prevents the pipes from breaking due to vibration. When the transportation route changes and the refrigeration area needs to be adjusted, the operating parameters of the motor 604 can be adjusted to change the moving speed and range of the refrigeration guide 611, achieving focused refrigeration in localized areas. After the transportation task is completed, the frame can be disassembled within 15 minutes by pulling the stop ratchet 508 and rotating the nut 506. The volume of each component is reduced by 60% after disassembly, facilitating warehousing and empty container return. For the refrigeration unit 601 or the corrugated hose 603 that requires maintenance, they can be disassembled and replaced individually without the need for overall scrapping, significantly reducing maintenance costs. This completes the usage process of a detachable refrigerated container device.
