[0001] This utility model belongs to the field of refrigerated truck body technology, and in particular relates to a novel refrigerated truck body panel assembly structure. Background Technology

[0002] Refrigerated trucks are widely used as core transportation equipment in cold chain logistics. The refrigerated compartment is the main component of a refrigerated truck, and its insulation performance, structural stability, and assembly efficiency directly affect the quality of cargo transportation and operating costs.

[0003] Chinese utility model patent CN215361582U discloses a novel refrigerated truck body panel assembly structure. This structure offers more convenient and faster positioning and assembly, eliminating the need for edge plates and thus reducing production costs and complexity, while improving production efficiency and quality. However, it does not address the gaps between the panel components, which negatively impacts the overall insulation performance of the refrigerated truck body. Therefore, there is an urgent need to improve existing refrigerated truck body panel assembly structures and provide a novel assembly structure that facilitates sealing at the joints. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a refrigerated truck panel assembly structure that is reasonably designed, simple in structure, and facilitates sealing of panel joints, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel refrigerated truck body assembly structure includes a base plate and a pressure plate. A side connecting profile is fixedly installed above the right angle of the base plate. The side connecting profile is located at the splice of two side plates. The side plate has a butt joint at one end near the side connecting profile. The outer wall of the butt joint has symmetrical protrusions. The side connecting profile has a butt groove adapted to the butt joint. The inner wall of the butt groove has symmetrical concave parts that are adapted to the protrusions. Multiple nuts are embedded and fixed at equal intervals along the vertical direction on the surface of the side plate near the side connecting profile. The pressure plate is "W" shaped and is fixedly connected to two adjacent side plates by two sets of bolts. A waterproof and heat-insulating rubber sealing gasket is adhered to the side of the pressure plate near the side plate.

[0007] Preferably, the side connecting profile is an aluminum alloy extruded profile, and the outer wall of the side connecting profile is provided with a number of reinforcing ribs at equal intervals.

[0008] Preferably, the base plate and the plurality of side plates are composite insulation boards, the composite insulation board comprising an inner stainless steel plate, an outer color steel plate, and a polyurethane foam core material filled between the stainless steel plate and the color steel plate.

[0009] Preferably, the mating part is inserted into the side connecting profile through a mating groove, and the protrusion is engaged and positioned with the side connecting profile through a concave part.

[0010] Preferably, the inner wall of the docking groove is provided with a grouting channel extending in the vertical direction, and the interior of the side connecting profile is provided with a filling cavity with a rectangular cross-section extending in the vertical direction. The filling cavity and the grouting channel are connected by a number of through holes.

[0011] Preferably, the cavity is filled with polyurethane sealant, which can enter the grouting channel through several through holes and fill the gap between the butt joint and the side connecting profile.

[0012] Preferably, both sets of bolts are distributed at equal intervals along the vertical direction and correspond one-to-one with multiple nuts and are threadedly connected. The pressure plate also has through holes for installing bolts inside.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the device utilizes the mating groove on the side wall of the side connecting profile to mate with the mating part on one side of the side plate. The symmetrical protrusions on the outer wall of the mating part can engage with the corresponding recesses on the inner wall of the mating groove to position the side plate. Subsequently, several corresponding nuts and bolts are used to fix the two ends of the "W"-shaped pressure plate to the two adjacent side plates respectively. While enhancing the connection strength, it can also press the waterproof and heat-insulating rubber sealing gasket between the side plate and the side connecting profile, which facilitates sealing and heat insulation of the connection seam between the two.

[0015] When this utility model injects polyurethane sealant into the filling cavity, the polyurethane sealant can enter the grouting channel through several through holes and fill the gap between the butt joint and the side connecting profile, thereby ensuring that there are no gaps between the body panels of the refrigerated truck. Moreover, the body panels adopt a multi-layer composite structure, including a stainless steel plate in the inner layer, a color steel plate in the outer layer, and a polyurethane foam core material filled between the stainless steel plate and the color steel plate. It has excellent thermal insulation performance, good flame retardant performance, and stable chemical and environmental performance. While simplifying the assembly structure, it can ensure that the overall thermal insulation performance of the refrigerated truck is not affected. Attached Figure Description

The recess 8 and the protrusion 6 are adapted to each other. Multiple nuts 12 are embedded and fixed at equal intervals along the vertical direction on the surface of one end of the side plate 3 near the side connecting profile 2. The pressure plate 13 is "W" shaped and is fixedly connected to two adjacent side plates 3 by two sets of bolts 16 respectively. A waterproof and heat-insulating rubber sealing gasket 14 is adhered to the side of the pressure plate 13 near the side plate 3.

[0026] As a preferred embodiment, based on the above structure, the side connecting profile 2 is further made of aluminum alloy extrusion profile, and the outer wall of the side connecting profile 2 is provided with a number of reinforcing ribs 4 at equal intervals.

[0027] In this embodiment, the side connecting profile 2 facilitates a stable connection between multiple side panels 3, and facilitates the assembly of the refrigerated truck compartment.

[0028] As a preferred embodiment, based on the above structure, the bottom plate 1 and the multiple side plates 3 are further all composite insulation boards, which include a stainless steel plate in the inner layer, a color steel plate in the outer layer, and a polyurethane foam core material filled between the stainless steel plate and the color steel plate.

[0029] In this embodiment, the carriage body adopts a multi-layer composite structure, which has excellent thermal insulation performance, good flame retardant performance, and stable chemical and environmental performance.

[0030] In a preferred embodiment, based on the above structure, the mating part 5 is inserted into the side connecting profile 2 through the mating groove 7, and the protrusion 6 is engaged and positioned with the side connecting profile 2 through the concave part 8.

[0031] In this embodiment, the mating part 5, the protrusion 6, the mating groove 7 and the recess 8 are used to facilitate stable mating, installation and positioning between the side connecting profile 2 and the side plate 3.

[0032] As a preferred embodiment, based on the above structure, the inner wall of the docking groove 7 is provided with a grouting channel 9 extending in the vertical direction, and the interior of the side connecting profile 2 is provided with a filling cavity 10 with a rectangular cross-section extending in the vertical direction. The filling cavity 10 and the grouting channel 9 are connected by a number of through holes 11.

[0033] As a preferred embodiment, based on the above structure, the filling cavity 10 is further filled with polyurethane sealant. The polyurethane sealant can enter the grouting channel 9 through several through holes 11 and fill the gap between the mating part 5 and the side connecting profile 2.

[0034] In this embodiment, when polyurethane sealant is injected into the filling cavity 10, the polyurethane sealant can enter the grouting channel 9 through several through holes 11 and fill the gap between the mating part 5 and the side connecting profile 2, which facilitates the filling and sealing of the gap and avoids affecting the overall refrigeration effect of the carriage.

[0035] As a preferred embodiment, based on the above structure, the two sets of bolts 16 are evenly distributed in the vertical direction and correspond one-to-one with multiple nuts 12 and are threadedly connected. The pressure plate 13 also has through holes 15 for installing bolts 16 inside.

[0036] In this embodiment, a number of one-to-one nuts 12 and bolts 16 are used to facilitate the fixed connection between the two ends of the pressure plate 13 and the two adjacent side plates 3 respectively. At the same time, the waterproof and heat-insulating rubber sealing gasket 14 can be pressed between the side plate 3 and the side connecting profile 2, so as to facilitate the sealing and heat insulation of the connection seam between the two.

[0037] The working principle of this utility model is as follows:

[0038] In use, firstly, the four side connecting profiles 2 are fixedly installed at the four right angles of the base plate 1. Then, multiple side plates 3 are installed sequentially between two adjacent side connecting profiles 2 by inserting them from top to bottom. The mating grooves 7 opened on the side walls of the side connecting profiles 2 are used to mate with the mating parts 5 on one side of the side plates 3. The symmetrical protrusions 6 on the outer walls of the mating parts 5 can be engaged in the corresponding recesses 8 on the inner walls of the mating grooves 7 to position the side plates 3. Then, several corresponding nuts 12 and bolts 16 are used to fix the two ends of the "W"-shaped pressure plate 13 to the two adjacent side plates 3 respectively. While enhancing the connection strength, the waterproof and heat-insulating rubber sealing gasket 14 can also be pressed between the side plates 3 and the side connecting profiles 2 to seal the connection between the two.

[0039] After the multiple side panels 3 are installed, polyurethane sealant can be injected into the filling cavity 10 inside the side connecting profile 2. The polyurethane sealant can enter the grouting channel 9 through several through holes 11, thereby filling the gap between the butt joint 5 and the side connecting profile 2, thus ensuring that there is no gap between the body panels of the car body. Moreover, the body panels of the car body adopt a multi-layer composite structure, including a stainless steel plate in the inner layer, a color steel plate in the outer layer, and a polyurethane foam core material filled between the stainless steel plate and the color steel plate. It has excellent thermal insulation performance, good flame retardant performance, and stable chemical and environmental performance. While simplifying the assembly structure, it can ensure that the overall thermal insulation performance of the refrigerated car body is not affected.

[0040] Finally, the top plate, which is completely identical in structure and size to the bottom plate 1, is fixedly installed on the top of the side connecting profile 2 and the side plate 3, and the truck door is installed, thus completing the entire assembly process of this refrigerated truck.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
