[0046] First Implementation Method
[0047] Figure 1 and Figure 2 A panel joint assembly 110 for an insulated container according to this application is shown. The insulated container has insulation panels 100. The panel joint assembly 110 is disposed at the joint between two adjacent insulation panels 100. The panel joint assembly 110 includes an insulation panel 114, an outer sealing member 111, an inner sealing member 112, and an elastic member 113. The insulation panel 114 is disposed on the inner side of each insulation panel 100 and located at the end of the insulation panel 100. The insulation panel 114 is provided with a reserved slot 1141. The outer sealing member 111 is respectively connected to the outer side of the two adjacent insulation panels 100 to cover the outer side of the joint between the insulation panels 100. The inner sealing member 112 is disposed on the inner side of the two adjacent insulation panels 100, and its two sides extend into the reserved slot 1141 to cover the inner side of the joint. The elastic member 113 is disposed within the joint.
[0048] According to the panel joint assembly 110 of the insulated container of this application, the outer sealing element 111 and the inner sealing element 112 prevent heat, air and moisture from passing through the joints between the insulation panels 100. The elastic element 113 seals the joints between the insulation panels 100 and overcomes the defect of excessively large joints caused by processing and installation errors between the insulation panels 100, further improving the sealing performance and insulation performance between the insulation panels 100. In addition, the inner sealing element 112 is connected to the insulation panels 100 through the reserved slot 1141 of the insulation panel 114, which is convenient for installation and reduces the risk of accidental damage to the insulation panels 100 when installing the inner sealing element 112.
[0049] The panel joint assembly 110 according to the first embodiment is applicable between insulation panels 100 arranged vertically. The components of the panel joint assembly 110 are described in detail below.
[0050] Reference Figure 1 The panel joint assembly 110 also includes an outer panel 115 and an inner lining panel 116. The outer panel 115 is disposed on the outer side of the insulation board 100, and the inner lining panel 116 is disposed on the inner side of the insulation board 100, with the edge of the inner lining panel 116 near the inner sealing member 112 connected to the heat insulation board 114. The arrangement of the outer panel 115 and the inner lining panel 116 facilitates the protection of the insulation board 100.
[0051] Reference Figure 1 and Figure 2 The heat insulation plate 114 has a stepped groove 1142 at one end near the inner sealing member 112. The stepped groove 1142 includes a mating surface 1144 and a insertion surface 1145. The mating surface 1144 is mated to the side of the inner sealing member 112, while the insertion surface 1145 is opposite to the side of the inner sealing member 112, and a reserved slot 1141 is correspondingly provided to the insertion surface 1145. Fasteners 1143, which can be self-tapping screws, are provided through the heat insulation plate 114. The end of the fastener 1143 is inserted into the insulation plate 100 and threadedly connected to the insulation plate 100, thereby fixing the heat insulation plate 114 to the insulation plate 100. The heat insulation plate 114 has at least two fasteners 1143, and at least a portion of the axis of the fasteners 1143 passes through the mating surface 1144, ensuring the structural strength of the position where the heat insulation plate 114 connects to the inner sealing member 112.
[0052] Reference Figure 1 and Figure 2 The inner sealing element 112 has an L-shaped cross-section and is made of PP material. When installing the inner sealing element 112, bend the inner sealing element 112 and insert both sides of the inner sealing element 112 into the reserved slot 1141. The installation is convenient. Due to the material selection of the inner sealing element 112, the inner sealing element 112 can still be installed smoothly even when the insulation board 100 has certain installation and processing errors.
[0053] Reference Figure 1 and Figure 2 The outer sealing member 111 includes a first overlapping piece 1111, a connecting piece 1113, and a second overlapping piece 1112. The first overlapping piece 1111 is connected to the outer panel 115 of one side of the insulation board 100, while the second overlapping piece 1112 is connected to the outer panel 115 of the other side of the insulation board 100. The connecting piece 1113 has an L-shaped cross-section, with one side connected to the first overlapping piece 1111 and the other side connected to the second overlapping piece 1112, thereby separating the adjacent insulation board 100 from the outside environment and further protecting the insulation board 100. The connecting piece 1113 is clearance-fitted with the outer surface of the insulation board 100, leaving a buffer space between the connecting piece 1113 and the insulation board 100.
[0054] Because the arrangement of two adjacent insulation boards 100 is different, the joint structure between the insulation boards 100 will be different. Figure 1 Taking the insulation board 100 as an example, the two insulation boards 100 are perpendicular to each other and are protective insulation boards 100. One of the insulation boards 100 has a heat insulation board 114 that extends to the end of the other insulation board 100, and an elastic member 113 is disposed between the heat insulation board 114 and the end of the other insulation board 100.
[0055] Second Implementation Method
[0056] The panel joint assembly 110 according to the second embodiment is applicable between insulation boards 100 located on the same plane. Except for the structure of the connecting piece 1113 and the inner sealing member 112, the panel joint assembly 110 according to the second embodiment has a substantially the same structure as the panel joint assembly 110 according to the first embodiment. Therefore, the following will only describe the differences between the panel joint assembly 110 according to the second embodiment and the panel joint assembly 110 according to the first embodiment.
[0057] Reference Figure 3 Unlike the arrangement of the insulation boards 100 in the first embodiment, in the second embodiment, adjacent insulation boards 100 are on the same plane, the insulation boards 114 of the two insulation boards 100 have the same size, and the reserved slots 1141 between adjacent insulation boards 114 are arranged opposite each other.
[0058] Figure 3 and Figure 4A panel joint assembly 110 according to a second embodiment is shown, wherein, due to the opposing arrangement of the reserved slots 1141 between adjacent insulation panels 114, the cross-section of the inner sealing member 112 made of PP material is straight when installed between the insulation panels 114. Furthermore, the cross-section of the connecting piece 1113 is also straight, thereby sealing the joint between adjacent insulation panels 100 on the same plane, blocking the passage of heat, air, and moisture, and improving the airtightness between adjacent insulation panels 100. Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the application. Terms such as “set” appearing herein can mean either that one component is directly attached to another component or that one component is attached to another component via an intermediary. A feature described in one embodiment herein may be applied alone or in combination with other features to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.
[0059] This application has been described through the above embodiments; however, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this application to the described embodiments. Those skilled in the art will understand that many more variations and modifications can be made based on the teachings of this application, and all such variations and modifications fall within the scope of protection claimed in this application.
