[0048] Figure 1 A joint assembly 107 of a combined container according to the present invention is shown. The combined container includes at least two boxes 100. The joint assembly 107 includes a connecting shell 110, a heat insulating member 130, a connecting plate 120, and at least two elastic members 140. The connecting shell 110 is used to be at least partially arranged between two adjacent boxes 100. The heat insulating member 130 is arranged in the connecting shell 110. The connecting plate 120 is connected to the connecting shell 110, and both ends of the connecting plate 120 extend beyond the connecting shell 110, respectively, so as to be connected to the two adjacent boxes 100. At least two elastic members 140 are respectively arranged on both sides of the connecting shell 110, and the elastic members 140 are used to abut against the boxes 100.

[0049] According to the joint assembly 107 of the combined container of the utility model, the heat insulation member 130 is arranged in the connecting shell 110, and the connecting shell 110 is connected to the box body 100 through the connecting plate 120, which has good integrity, is convenient for controlling the installation size, reduces the difficulty of installation, and can be operated by one person. The connecting shell 110 is connected to the box body 100 through the elastic member 140, which not only has good sealing performance, but also provides a certain installation precision redundancy, further reducing the difficulty of installation.

[0050] Reference Figure 2 The utility model also provides a combined container, including at least two boxes 100 and a joint assembly 107 according to the above-mentioned combined container. The box 100 includes a side frame 101, and two adjacent boxes 100 are spliced ​​together through their respective side frames 101. The connecting shell 110 is at least partially arranged between the side frames 101, the connecting plate 120 is connected to the side frame 101, and the elastic member 140 abuts against the side frame 101. According to the combined container of the utility model, the integrity is good, the installation size is easy to control, the installation difficulty is reduced, and it can be operated by a single person. The connecting shell 110 is connected to the box 100 through the elastic member 140, which not only has good sealing performance, but also provides a certain installation precision redundancy, further reducing the installation difficulty.

[0051] Figure 3 Shown in detail Figure 2 The structure of the side frame 101 and the joint assembly 107 of the box body 100 of the combined container is as follows: Figure 3 As shown, the side frames 101 of the adjacent boxes 100 have a joint seam 102 and are structured to form a mounting groove 103 communicating with the joint seam 102, the connecting housing 110 is disposed in the mounting groove 103, the elastic member 140 abuts against the inner wall of the mounting groove 103, and the connecting plate 120 is located outside the mounting groove 103. When installing the joint assembly 107, the connecting housing 110 is placed in the mounting groove 103, and then the connecting plate 120 is connected and fixed to the adjacent side frame 101, so that the joint assembly 107 can be installed, and the installation difficulty is small.

[0052] Further, see Figure 2 and Figure 3 The side frame 101 protrudes to the inner side of the box body 100, the opening of the mounting groove 103 is located on the inner side of the box body 100, and the surface where the side frame 101 is connected to the connecting plate 120 is located on the inner side of the box body 100. Therefore, the seam assembly 107 can be arranged on the inner side of the box body 100, which can effectively block rainwater from penetrating between the side frames 101 of the box body 100, and the seam assembly 107 has better anti-corrosion and anti-aging performance.

[0053] As an alternative, the seam assembly 107 may also be arranged outside the box 100 to prevent rainwater from entering between the side frames 101 of adjacent boxes 100 (ie, the seams 102 ), thereby reducing corrosion of the box 100 .

[0054] Optionally, refer to Figure 3 The side frame 101 includes a splicing plate 104, an inner plate 105 and a sealing plate 106. The splicing plate 104 and the inner plate 105 are both bent plates in an L shape. The sealing plate 106 is also a bent plate in a Z shape. The first side of the sealing plate 106 is connected to the splicing plate 104, and the second side of the sealing plate 106 is connected to the inner plate 105. The adjacent sealing plates 106 are constructed to form a mounting groove 103, which is suitable for accommodating the connection shell 110 and the elastic member 140. A splicing seam 102 is formed between the adjacent splicing plates 104, which is suitable for connecting the splicing seam 102 with the mounting groove 103, so that external rainwater will be blocked by the splicing assembly 107. The connecting plate 120 is connected to the sealing plate 106, so as to fix the connection shell 110.

[0055] More specifically, regarding the structure of the stitching assembly 107, refer to Figure 1 and Figure 3 The connecting plate 120 and the connecting housing 110 are integrally formed, which can be injection molding or extrusion molding. Preferably, the connecting plate 120 and the connecting housing 110 are made of PVC (polyvinyl chloride), which is easy to process and can be slightly deformed, thereby reducing the installation accuracy requirements, improving the installation error tolerance, and facilitating operation and installation.

[0056] Optionally, refer to Figure 3 The seam assembly 107 includes a fastener 150, which is inserted into the connecting plate 120 and is used to connect to the box body 100. Specifically, the fastener 150 is threadedly connected to the surface of the sealing plate 106 of the side frame 101 extending outside the mounting groove 103. The fastener 150 can be a bolt or a screw. The seam assembly 107 includes at least two fasteners 150, which are respectively located on both sides of the connecting shell 110 and are respectively connected to the side frames 101 of the two boxes 100. The provision of the fastener 150 enables the seam assembly 107 to be detachably connected to the two adjacent boxes 100, and is easy to install.

[0057] Furthermore, the heat insulating component 130 is a PU (polyurethane) filler, and the heat insulating component 130 fills the internal space formed by the connecting shell 110 and the connecting plate 120, effectively blocking the heat radiated along the splicing seam 102 and the installation groove 103, thereby improving the thermal insulation performance of the splicing point of the combined container.

[0058] Depend on Figure 3It can be seen that the two elastic members 140 on both sides of the connection shell 110 are respectively abutted against the two inner side walls of the installation groove 103 that are perpendicular to the horizontal plane (i.e., the side walls of the sealing plates 106 of the two adjacent boxes 100), so that heat is not easily transferred between the connection shell 110 and the inner side walls of the installation groove 103, further improving the sealing and thermal insulation performance of the joint assembly 107. In addition, the provision of the elastic member 140 provides a certain degree of installation precision redundancy, further reducing the difficulty of installation.

[0059] Optionally, the elastic member 140 is a PVC member, so that the elastic member 140 has a good sealing effect when it abuts against the sealing plate 106. Further, the sealing plate 106 of the side frame 101 can also be a PVC plate, which can not only improve the sealing between the joint assembly 107 and the box body 100, but also reduce the installation accuracy requirements of the combined container, improve the installation error tolerance, and facilitate operation and installation.

[0060] Figure 1 A cross section of the stitching assembly 107 is shown, and the Figure 2 As shown, the depth direction D3D3 of the joint seam 102 between the boxes 100 is consistent with the length direction D1 of the combined container, and the boxes 100 are arranged along the width direction D2 of the combined container. The joint assembly 107 is used to extend along the length direction of the gap between adjacent boxes 100. In other words, the joint assembly 107 extends along the height direction of the combined container, so that the boxes 100 of the combined container are fully sealed and connected.

[0061] Reference Figure 1 and Figure 3 The elastic member 140 is provided with a protrusion 141 and a recessed portion 142. After the seam assembly 107 is installed, the protrusion 141 and the recessed portion 142 are alternately arranged in a direction parallel to the depth direction of the gap between adjacent boxes 100. In other words, the protrusion 141 and the recessed portion 142 are alternately arranged along the depth direction D3 of the seam 102 between the boxes 100, so that a plurality of contact positions are formed between the elastic member 140 and the inner side wall of the installation groove 103 along the depth direction D3 of the seam 102, thereby further enhancing the sealing performance between the seam assembly 107 and the box 100.

[0062] The utility model also provides a cold storage, comprising the above-mentioned combined container. The cold storage according to the utility model has low installation difficulty and good sealing performance.
