Description

Technical Field

[0001] The utility model belongs to the technical field of cold chain transportation, in particular to a refrigerated truck cargo box splicing structure. Background Art

[0002] With the growth of global trade and the complexity of supply chains, the demand for the transportation of food, medicine and other temperature-sensitive goods is increasing, especially cross-border transportation. With the advancement of science and technology, temperature control technology has been significantly improved, from traditional mechanical control to modern intelligent temperature control systems, ensuring that the goods are always kept within a safe temperature range during transportation. The demand for cold chain transportation varies significantly in different industries, such as food retail, biomedicine, etc., which puts forward higher customization requirements for the design of cargo boxes to meet specific transportation needs and environmental conditions.

[0003] After searching, the existing patent (publication number: CN218316965U) discloses a refrigerated truck cargo box splicing structure, which belongs to the field of cargo box splicing. A refrigerated truck cargo box splicing structure includes a vertical plate and a horizontal plate, a clamping block is arranged at the bottom of the vertical plate, and a clamping groove corresponding to the clamping block is arranged at the top of the horizontal plate, a sealing flow-blocking component is arranged on the inner side of the clamping groove, and the sealing flow-blocking component is used to seal the connection between the vertical plate and the horizontal plate, and the sealing flow-blocking component includes an adhesive pad, which is fixed to the bottom of the inner side of the clamping groove, and a sealing rubber pad is fixed on the top of the adhesive pad. A heating wire is arranged on the inner side of the clamping block, and a plurality of reinforcing components are arranged on the top of the sealing rubber pad. The reinforcing component includes an installation groove, and a connecting pad is arranged on the inner side of the installation groove. A sealing notch is arranged on the top of the connecting pad and the inner side of the installation groove, and the connecting pad is made of soft material; it can reduce the loss of water in the car box, thereby ensuring the persistence of the temperature in the car box and avoiding the deterioration of the items in the car box.

[0004] However, in the actual use of the above solution, heating the rubber with the heating wire will cause part of the material to melt, which may affect the strength and durability of the originally designed structure. Especially in refrigerated truck transportation, the cargo box needs to withstand various vibrations and impacts, and the strength of the structure is crucial. At the same time, after the rubber melts and re-solidifies, its sealing performance may become unstable. This may cause leakage or damage to the seal during transportation, affecting the temperature control and safety of the refrigerated goods, and once the heating wire is used to melt the rubber for sealing, the repair and replacement of the seal in the future may become more complicated and difficult. This may increase maintenance costs and time, especially when the sealing part needs to be replaced.

[0005] To this end, the utility model provides a refrigerated truck cargo box splicing structure. Utility Model Content

[0008] Through the above technical solution, by tightening the bolt, the insulation plate is driven to move downward through the thread between the bolt and the insulation plate, thereby squeezing the support plate and compressing the spring at the same time, so that the support plate uses the first hinge frame, the transmission column and the second hinge frame to drive the pressure plate to rotate with the rotating rod as the center, so that the pressure plate and the slot are more tightly engaged to ensure the sealing.

[0009] Furthermore, the sliding assembly includes a slide rail, and the inner side of the protection box is fixedly connected with a slide groove which is opposite to each other up and down and left and right, and the inner side of the slide groove is slidably connected with a slide rail, and the slide rail is fixedly connected to one end of the outer side of the fixed frame;

[0010] Through the above technical solution, the fixing frame and the internal structure can slide in the protective box through the sliding component, which is convenient for subsequent disassembly and cleaning. At the same time, a certain gap is set between the slide rail and the slide groove, which can be moved up and down to a certain extent.

[0011] Furthermore, a rubber layer is provided on the outer side of the inner side of the sealing door;

[0012] Through the above technical solution, by providing a rubber layer, the sealing performance between the sealing door and the protection box and the internal structure can be increased.

[0013] Furthermore, the maximum opening and closing angle of the pressure plates on both sides is smaller than the top width of the sealing frame;

[0014] Through the above technical solution, by setting the maximum opening and closing angle of the pressure plates on both sides to be smaller than the top width of the sealing frame, it is avoided that the sealing frame is affected during opening and closing.

[0015] Furthermore, the outer wall of the bottom end of the second hinged frame is circular;

[0016] According to the technical solution, by setting the outer wall of the bottom end of the second hinged frame to be circular, the second hinged frame is always in contact with the inner wall of the sealing frame when driving the pressure plate to rotate, thereby improving the sealing performance.

[0017] Further, the number of the springs is the same as the number of the bolts;

[0018] Through the above technical solution, by setting the same number of springs and bolts and setting the springs on the outside of the bolts, the stress of the springs can be kept consistent at all times.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model discloses a refrigerated truck cargo box splicing structure, which can drive the insulation plate to move toward the side of the sealing frame by rotating the bolts, thereby squeezing the support plate, and through the transmission of the first hinge frame, the transmission column, and the second hinge frame, the pressure plate and the card slot are driven to engage more tightly, thereby providing stable sealing and heat preservation for the compartment.
