Description

Technical Field

[0001] The utility model belongs to the technical field of containers, and specifically relates to a rear side sealing plate and a thermal insulation container. Background Art

[0002] A refrigerated container is a temperature-adjustable thermal insulation container with good heat insulation and capable of maintaining a certain low temperature requirement, suitable for the transportation and storage of various perishable foods. Based on the above functional requirements and for the convenience of the general assembly of the refrigerated container, the rear corner post and the inner side plate are connected by a rear side sealing plate.

[0003] In the prior art, a standard refrigerated container is often modified into a special refrigerated container. The rear side sealing plate of the standard refrigerated container type has grooves for subsequent installation of freshness preservation. However, the special refrigerated container type does not require grooves, and often switches for electrical appliances or lighting lamps are installed on the rear side sealing plate. In this case, the rear side sealing plate with grooves will cause interference and buttons and boxes cannot be installed. Therefore, the button box is selected to be installed on the inner side plate. In this case, the pipeline needs to be pre-buried and then foamed during sub-assembly, and the position cannot be changed later, which causes inconvenience in installation. If the rear side sealing plate is bent from ordinary aluminum plates, since the plates are of unconventional length, they are often purchased individually each time, and the surface of the ordinary aluminum plate in contact with the foaming layer is not roughened, so there is a hidden danger of delamination later. Therefore, during the process of modifying a standard refrigerated container into a special refrigerated container, the rear side sealing plate needs to be redesigned. At the same time, in the prior art, the pipeline needs to be fixed by using a fixed bracket and double-sided tape. When the pressure during foaming is too high, the circuit is easily washed away, resulting in a situation where the cable is not pulled smoothly, causing difficulties in wiring and replacement.

[0073] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0074] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense.

[0076] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and in itself does not indicate the relationship between various embodiments and / or settings discussed.

[0077] In some embodiments of the present application, as Figures 4 to 19 shown, it relates to a rear side sealing plate which is arranged to extend vertically between the inner side plate 200 and the rear corner post 300. The rear side sealing plate is used for the sealed connection between the inner side plate 200 and the rear corner post 300.

[0078] To meet the requirements of special containers in refrigerated containers, a button box 110 needs to be installed according to the customer's requirements. Since special containers in refrigerated containers generally use standard refrigerated containers for transformation, the rear side sealing plate of the standard refrigerated container includes a groove structure for installing a fresh-keeping tank. If the button box 110 is installed here, interference problems will occur.

[0079] As Figure 3 shown, if the button box 110 is installed on the inner side plate 200, the cable needs to be pre-buried and then foamed during sub-assembly, and the position cannot be changed later, which causes inconvenience to the installation. If the rear side sealing plate is bent from ordinary aluminum plates, since the plates are unusually long, they are often purchased separately each time, and the surface of the ordinary aluminum plate in contact with the foaming layer is not roughened, there will be a potential risk of delamination later.

[0080] In addition, as shown in 1, Figure 2 shown, the fixing bracket 610 is pasted on the rear side sealing plate 630 by means of a double-sided tape 620, and the cable 400 extends along the cavity formed by the fixing bracket 610 and the rear side sealing plate 630. When foaming, the pressure is too high and it is easy to wash away the cable 400 and the fixing bracket 610, resulting in an unsmooth cable pulling situation, which causes difficulties in wiring and replacement.

[0081] Therefore, in some embodiments of the present application, the rear side sealing plate includes at least one cable groove and a rear side sealing plate unit 130. The rear side sealing plate unit 130 is used for the sealed connection between the inner side plate 200 and the rear corner post 300.

[0082] In some embodiments of the present application, the rear side sealing plate unit 130 is of an integral structure. One end of the rear side sealing plate unit 130 is connected to the inner side plate 200, and the other end of the rear side sealing plate unit 130 is hermetically inserted into the rear corner post 300.

[0083] Specifically, one end of the rear side sealing plate unit 130 is connected to the inner side plate 200 by using rivets. Sealant is used for sealing at this connection.

[0084] In some other embodiments, both the inner side plate 200 and the rear side sealing plate unit 130 are made of non-metallic materials. The rear side sealing plate unit 130 and the inner side plate 200 can be connected by welding.

[0085] Specifically, the rear side sealing plate unit 130 can be made of PVC or PP materials and is integrally formed by an extrusion process.

[0086] In some other embodiments of the present application, the rear side sealing plate unit 130 is of a split structure. The rear side sealing plate unit 130 includes a rear side sealing plate body 131 and a connecting member 132.

[0087] One end of the rear side sealing plate body 131 is used for connecting to the inner side plate 200.

[0088] The other end of the rear side sealing plate body 131 is inserted into one end of the connecting member 132.

[0089] The other end of the connecting member 132 is used for connecting to the rear corner post 300.

[0090] Specifically, the rear side sealing plate body 131 is made of a metal material. The connecting member 132 is a PVC profile.

[0091] Specifically, the cable groove extends along the rear side sealing plate body 131.

[0092] In some embodiments of the present application, the cable groove and the rear side sealing plate unit 130 are of an integral structure. The extrusion forming rate of the profile is increased, and the cable groove increases the strength of the rear side sealing plate unit 130. The cable groove is used for the extension setting of the cable.

[0093] In some other embodiments of the present application, the rear side sealing plate further includes a button box 110.

[0094] In order to facilitate the installation of the button box 110, the button box 110 is designed to be inserted into the cable groove.

[0095] The cable trough extends along the rear side sealing plate unit 130.

[0096] The cable trough extends along the side of the rear side sealing plate unit 130 close to the outside of the container.

[0097] Specifically, the cable trough extends along the side of the rear side sealing plate body 131 close to the foaming layer of the container.

[0098] The cable 400 extends along the inside of the cable trough.

[0099] When the cable 400 extends out of the cable trough, it is inserted into the button box 110 and electrically connected to the electrical components in the button box 110.

[0100] The cable trough can ensure the regular routing of the cable 400. It can avoid the cable 400 being squeezed and deformed during the foaming process of the container or being washed away due to excessive pressure during foaming, resulting in the situation that the cable 400 is not smoothly pulled, causing difficulties in wiring and replacement.

[0101] In some embodiments of the present application, in order to facilitate the insertion of the cable 400 into the button box 110, the cable trough includes a cable trough body 122 and a button box installation part. The button box installation part is formed on the cable trough body 122. The button box installation part is used for the installation of the button box 110.

[0102] In some embodiments of the present application, the button box installation part is an installation groove formed on the cable trough body 122, and the installation groove is used for installing the button box 110.

[0103] The installation groove communicates with the cable trough.

[0104] The button box 110 includes a button box body 111 and a plug-in part 112 formed at the end of the button box body 111.

[0105] The plug-in part 112 is formed at the end of the button box body 111. When the button box 110 is installed at the installation groove, the plug-in part 112 located at the end of the button box body 111 is inserted into the cable trough.

[0106] Specifically, in order to facilitate the insertion of the plug-in part 112 into the cable trough, the plug-in part 112 can be made of a PE block.

[0107] In some embodiments of the present application, the button box body 111 includes a box body 1111, a button cover plate 1112 and a button 1113. A cavity 1114 is formed inside the box body 1111, an open end 1115 is formed at the end of the box body 1111, the open end 1115 communicates with the cavity 1114, and the button cover plate 1112 is used for closing the open end 1115. The button 1113 is installed on the button cover plate 1112.

[0108] The cavity 1114 communicates with the cable groove, and the cable 400 enters the cavity 1114 through the cable groove and is electrically connected to the button 1113.

[0109] Specifically, the button cover plate 1112 is connected to the box body 1111 through the fastening member 1116.

[0110] The cable groove body 122 can adopt a closed annular member 1221 or a semi-closed annular member 1222.

[0111] Such as Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 As shown, specifically, a second through cavity 123 is formed in the closed annular member 1221, and the cable 400 passes through the second through cavity 123.

[0112] For example, the closed annular member 1221 can have a cross-section in the shape of a circular ring, a triangular ring, a rectangular ring, etc.

[0113] The second through cavity 123 is formed within a circular ring, a triangular ring, or a rectangular ring.

[0114] There is no limit to the specific structural form of the closed annular member 1221.

[0115] Such as Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 16 、 Figure 17 、 Figure 18 、 Figure 19 As shown, specifically, a first through cavity 121 is formed in the semi-closed annular member 1222, and the cable 400 passes through the first through cavity 121.

[0116] For example, the semi-closed annular member 1222 can adopt two oppositely arranged L-shaped structures, and the two oppositely arranged L-shaped structures are an integral structure with the rear side plate body 131.

[0117] The bent ends of the two L-shaped structures are oppositely arranged to form the opening part of the semi-closed annular member 1222, and the bent ends of the two L-shaped structures are used to prevent the cable 400 from falling out therefrom.

[0118] In some other embodiments, the cable groove can adopt an L-shaped semi-closed annular member 1222. As Figure 16 shown, a first through cavity 121 is formed by enclosing between the L-shaped structure and the rear side plate unit 130. The cable 400 extends along the first through cavity 121.

[0119] Specifically, such as Figure 16As shown, one end of the L-shaped structure is connected to the rear side sealing plate unit 130, and the end of the other end of the L-shaped structure is bent toward the rear side sealing plate unit 130 side, so as to prevent the cable 400 from falling out therefrom.

[0120] The closed annular member 1221 or the semi-closed annular member 1222 can prevent the cable 400 from falling out therefrom, and can ensure that the cable 400 will not be displaced, squeezed, etc. due to the impact of the foaming pressure during the foaming process.

[0121] At the same time, during the process of integrally forming with the rear side sealing plate unit 130, the cable groove can improve the forming rate of the integral forming of the material, and can increase its overall strength at the same time.

[0122] In some other embodiments of the present application, such as Figure 18 、 Figure 19 As shown, the number of cable grooves can be multiple, which can be used to limit multiple cables 400 at the same time.

[0123] In some embodiments of the present application, a foaming wave surface 133 is formed on the side of the rear side sealing plate unit 130 close to the foaming layer 500. The foaming wave surface 133 is wavy, and the height difference between the wave crest and the wave trough is 0.2 mm to 0.4 mm, and the distance between two adjacent wave crests is 0.8 mm to 1 mm. The foaming wave surface 133 and the foaming layer 500 are easily bonded together during the foaming process, so as to prevent separation between the foaming wave surface 133 and the foaming layer 500.

[0124] Specifically, the foaming wave surface 133 is formed on the side of the rear side sealing plate body 131 close to the foaming layer 500.

[0125] In addition, the cable groove body 122 is arranged on the side of the rear side sealing plate body 131 close to the foaming layer 500, and the cable groove body 122 can increase the connection stability between the rear side sealing plate body 131 and the foaming layer 500.

[0126] Forming the cable groove body 122 on one side surface of the rear side sealing plate body 131 can make the mold opening strength of the rear side sealing plate unit 130 high, the molding good, and not easy to deform.

[0127] Specifically, the foaming wave surface 133 can also extend and be formed on the cable groove body 122. The connection strength between the rear side sealing plate unit 130 and the foaming layer 500 can be further improved.

[0128] In some embodiments of the present application, an anti-wear concave-convex surface 134 is formed on the surface of the rear side sealing plate unit 130 close to the inner side of the container, and the anti-wear concave-convex surface 134 is used to increase the anti-wear property of the rear side sealing plate unit 130.

[0129] Specifically, the anti-wear concave-convex surface 134 is formed on one surface close to the inner side of the container.

[0130] The vertical distance between the concave surface and the convex surface of the anti-wear concave-convex surface 134 is between 0.2 mm and 0.4 mm. The distance between two adjacent convex surfaces is between 5 and 10 mm.

[0131] In the description of the above embodiments, the specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0132] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
