[0029] In a specific embodiment of the present invention, Figure 1 As shown, a refrigerated truck cargo box that is easy to install includes a cargo box top plate 1, a cargo box bottom plate 2, a cargo box rear plate 3, two cargo box side plates 4 and a box door 14. The top and bottom ends of the two cargo box side plates 4 are plugged with L-shaped connecting plates 5, and the two ends of the cargo box top plate 1 are respectively plugged with the two L-shaped connecting plates 5 located at the top, and the two ends of the cargo box bottom plate 2 are respectively plugged with the two L-shaped connecting plates 5 located at the bottom; the middle position of the bottom and the top of the inner side surfaces of the two cargo box side plates 4 is provided with a first limiting component 7; the cargo box rear plate 3 is respectively connected to the cargo box top plate 1, the cargo box bottom plate 2, the cargo box rear plate 3 and the two cargo box side plates 4 through the second limiting component 8, and the box door 6 is hinged on the side walls of the two cargo box side plates 4.

[0030] By connecting the L-shaped connecting plates 5, the frame structure of the shipping box can be preliminarily constructed, laying a foundation for subsequent installation and overall stability.

[0031] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the first limiting assembly 7 includes a mounting block 701, which is fixedly connected to the inner wall of the cargo box side plate 4; a limiting hole 702 is vertically penetrated on the mounting block 701, and sliding rods 703 are horizontally arranged at both ends of the limiting hole 702, and the ends of the two sliding rods 703 that are away from each other penetrate the mounting block 701 and are slidably connected thereto, and the ends of the two sliding rods 703 that are close to each other are fixedly connected to the first limiting block 704, and the cross-sections of the two first limiting blocks 704 are triangular and symmetrically arranged; a compression spring 705 is sleeved on the outer walls of the two sliding rods 703, one end of the compression spring 705 is fixedly connected to the inner wall of the mounting block 701, and the other end of the compression spring 705 is fixedly connected to the side wall of the first limiting block 704; the middle positions at both ends of the bottom surface of the cargo box top plate 1 and the top surface of the cargo box bottom plate 2 are fixedly connected to the first limiting plate 706, and the top of the first limiting plate 706 is fixedly connected to the second limiting block 707 that cooperates with the first limiting block 704.

[0032] After the top plate 1 and the bottom plate 2 of the cargo box are connected with the side plates 4 of the cargo box through the L-shaped connecting plate 5, the second limit block 707 on the first limit plate 706 is inserted into the limit hole 702, squeezing the first limit block 704, so that the slide bar 703 compresses the compression spring 705 and slides to both sides. When the second limit block 707 is fully inserted, under the elastic force of the compression spring 705, the first limit block 704 tightly clamps the second limit block 707, thereby limiting the displacement of the top plate 1 and the bottom plate 2 of the cargo box in the vertical direction, further enhancing the stability of the connection between the side plates 4 and the top plate 1 and the bottom plate 2 of the cargo box, and preventing the loosening of the cargo box plates due to factors such as vibration during transportation.

[0033] Specifically, a horizontally arranged support plate 708 is fixedly connected to the first limiting plate 706 , and the support plate 708 is arranged in contact with the mounting block 701 .

[0034] By setting the support plate 708, when the second limit block 707 on the first limit plate 7 on the cargo box top plate 1 is inserted into the limit hole 702, the support plate 708 on the first limit plate 7 on the cargo box top plate 1 contacts the top surface of the mounting block 701 at the top end of the cargo box side plate 4, so that the mounting block 701 supports the cargo box top plate 1. When the support plate 708 on the first limit plate 7 on the cargo box bottom plate 2 contacts the bottom surface of the mounting block 701 at the bottom end of the cargo box side plate 4, the first limit plate 7 supports the cargo box side plate 4, thereby improving the overall stability of the carriage.

[0035] In a specific embodiment of the present invention, Figure 1 , Figure 5 and Figure 6 As shown, the second limiting assembly 8 includes four U-shaped limiting seats 801 and four second limiting plates 802. The four U-shaped limiting seats 801 are respectively fixedly connected to the inner walls of the cargo box top plate 1, the cargo box bottom plate 2 and the two cargo box side plates 4; the four second limiting plates 802 are fixedly connected to the inner wall of the cargo box rear plate 3, and the four second limiting plates 802 are arranged in a one-to-one correspondence with the four U-shaped limiting seats 801, and the second limiting plates 802 are plugged into the inner wall of the U-shaped limiting seat 801; both the U-shaped limiting seat 801 and the second limiting plate 802 are provided with threaded holes 803, and the threaded holes 803 are threadedly connected with threaded rods 804.

[0036] After the rear plate 3 of the cargo box and other components are initially positioned, the second limit plate 802 is inserted into the corresponding U-shaped limit seat 801, and then the threaded rod 804 is screwed into the threaded hole 803 to further tighten the connection, so that the rear plate 3 of the cargo box is tightly connected to the top plate 1 of the cargo box, the bottom plate 2 of the cargo box, and the two side plates 4 of the cargo box, effectively enhancing the strength and stability of the overall structure of the cargo box, avoiding loosening and cracking of the rear plate 3 of the cargo box during transportation, and ensuring the thermal insulation performance and normal use of the cargo box.

[0037] In a specific embodiment of the present invention, Figure 7 and Figure 8 As shown, both ends of the cargo box top plate 1, cargo box bottom plate 2 and two cargo box side plates 4 are fixedly connected with plug-in plates 9 along their length direction, and slots 10 adapted to the plug-in plates 9 are opened on both side surfaces of the L-shaped connecting plate 5.

[0038] Specifically, sealing rubber strips 11 are embedded on the side surface of the plug board 9 and the inner bottom surface of the slot 10 .

[0039] The provision of the sealing rubber strip 11 can effectively improve the sealing performance of the cargo box, prevent outside air from entering the cargo box and affecting the temperature stability in the cargo box, ensure that the refrigerated truck cargo box can better meet the transportation needs of temperature-sensitive goods and ensure the quality and safety of the goods.

[0040] In a specific embodiment of the present invention, Figure 5 and Figure 6 As shown, the four L-shaped connecting plates 5 are fixedly connected with an L-shaped connecting block 12 near one end of the cargo box rear plate 3. The L-shaped connecting block 12 is provided with an L-shaped mounting groove 13, and the four corners of the cargo box rear plate 3 are inserted into the L-shaped mounting groove 13.

[0041] The L-shaped connecting block 12 provides accurate positioning and stable support for the installation of the cargo box rear panel 3, making the connection between the cargo box rear panel 3 and the L-shaped connecting plate 5 more secure, further enhancing the stability of the overall structure of the cargo box, and facilitating the installation of the cargo box rear panel 3, thereby improving the installation efficiency. It should be noted that after the four corners of the cargo box rear panel 3 are inserted into the L-shaped installation groove 13, the connection between the cargo box rear panel 3 and the cargo box side panels 4, the cargo box top panel 1, and the cargo box bottom panel 2 needs to be sealed.

[0042] Working principle of the present invention: When installing the cargo box of a refrigerated truck, first use the L-shaped connecting plate 5 to initially build the cargo box frame by plugging the cargo box side panels 4 with the cargo box top panel 1 and cargo box bottom panel 2. In this process, the plug-in plates 9 at both ends of the cargo box top panel 1, cargo box bottom panel 2 and cargo box side panels 4 are tightly matched with the slots 10 on the L-shaped connecting plate 5, and the sealing rubber strips 11 on the bottom surface of the slots 10 and the sealing rubber strips 11 on the side of the plug-in plate 9 squeeze each other to form a preliminary sealing effect, reducing the possibility of outside air entering the cargo box. At the same time, the L-shaped mounting groove 13 on the L-shaped connecting block 12 at one end of the cargo box rear panel 3 of the L-shaped connecting plate 5 provides precise positioning for the installation of the cargo box rear panel 3, and the four corners of the cargo box rear panel 3 are inserted into the L-shaped mounting groove 13, so that the cargo box rear panel 3 and the L-shaped connecting plate 5 are initially connected.

[0043] After completing the above preliminary connection, the first limit assembly 7 and the second limit assembly 8 begin to function. For the first limit assembly 7, after the cargo box top plate 1 and the cargo box bottom plate 2 are plugged with the cargo box side plate 4 through the L-shaped connecting plate 5, the second limit block 707 on the first limit plate 706 on the bottom surface of the cargo box top plate 1 and the top surface of the cargo box bottom plate 2 is inserted into the limit hole 702 on the inner side mounting block 701 of the cargo box side plate 4. During the insertion process, the second limit block 707 squeezes the first limit block 704, so that the slide bar 703 compresses the compression spring 705 and slides to both sides. When the second limit block 707 is fully inserted, under the elastic force of the compression spring 705, the first limit block 704 tightly clamps the second limit block 707, limiting the displacement of the cargo box top plate 1 and the cargo box bottom plate 2 in the vertical direction, and enhancing the stability of the connection between the cargo box side plate 4 and the top plate 1 and the bottom plate 2. At the same time, the support plate 708 on the first limiting plate 706 is in contact with the mounting block 701, further improving the stability of the overall structure.

[0044] For the second limiting assembly 8, after the cargo box rear plate 3 and other components are initially positioned, the second limiting plate 802 on the inner wall of the cargo box rear plate 3 is inserted into the corresponding U-shaped limiting seat 801 on the inner walls of the cargo box top plate 1, the cargo box bottom plate 2 and the two cargo box side plates 4, and then the threaded rod 804 is screwed into the threaded hole 803 on the U-shaped limiting seat 801 and the second limiting plate 802 to further tighten the connection, so that the cargo box rear plate 3 is tightly connected with the cargo box top plate 1, the cargo box bottom plate 2 and the two cargo box side plates 4, which greatly enhances the strength and stability of the overall structure of the cargo box.
