Description

Technical Field

[0001] The utility model belongs to the technical field of containers, and in particular relates to a rear top sealing plate connecting piece and a heat-insulating container. Background Art

[0002] The insulated container includes the top plate assembly and the rear frame assembly. The top plate includes the outer top plate, the inner top plate, the insulation layer and other structures, and the rear frame includes the rear frame lintel. The rear frame lintel and the inner top plate are sealed and connected by the rear top sealing plate and the rear top PVC profile. Although the connection between the rear top sealing plate and the rear top PVC profile can ensure the thermal insulation and sealing performance of the rear frame lintel and the inner top plate, the rear top sealing plate and the rear top PVC profile are made of two different materials. The two need to be connected as one by plugging, and sealant needs to be applied at the plug-in seam, which makes the assembly process complicated and there is also the risk of water vapor entering the interior at the plug-in seam; since the rear top sealing plate is generally a stamping part, it is very easy to have molding defects, which makes the assembly of the rear top sealing plate and the rear top PVC profile difficult and inefficient. At the same time, there is often a need to install a door curtain track at the door end, and it is necessary to pre-embed the back plate in the rear top sealing plate for riveting rivets to ensure that the door curtain does not damage the rear top sealing plate during use. If the back panel is connected by bonding or other methods, the installation procedure and assembly time will be increased.

[0003] At the same time, the rear top cover is a metal part, which is a material with obvious heat conduction, which reduces the insulation performance of the insulated container to a certain extent. At the same time, the low temperature impact performance of the metal rear top cover will also be reduced when it is exposed to low temperatures in the box, such as below -20℃, and it is easy to deform or even crack.

[0004] Therefore, it is a technical problem to be solved urgently to develop a rear top sealing plate connector and an insulated container, in which the rear top sealing plate and the rear top PVC profile are an integrated structure and a door curtain track can be installed conveniently and stably.

Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0076] In some embodiments of the present application, a rear top sealing plate connecting member is provided, which is used to connect between the inner top plate 100 and the rear frame door lintel 200. The rear top sealing plate connecting member extends between the inner top plate 100 and the rear frame door lintel 200 in a horizontal direction.

[0077] In some embodiments of the present application, the rear top sealing plate connector includes a rear top sealing plate connector body 310 and at least one plug-in portion.

[0078] The rear top sealing plate connector body 310 extends horizontally from the inner top plate 100 to the rear frame lintel 200. This can avoid the need to plug the split structure rear top sealing plate and the rear top PVC profile into a plug-in connection, which requires sealant to be applied at the plug-in seam, resulting in a complicated assembly process. At the same time, it can avoid the hidden danger of water vapor entering the interior at the plug-in seam; it can avoid the use of metal parts in the rear top sealing plate, which has obvious heat conductivity and reduces the insulation performance of the insulated container to a certain extent, as well as the reduction of its strength in a low temperature environment.

[0079] In some embodiments of the present application, the rear top sealing plate connecting member body 310 is made of non-metallic materials. Specifically, the rear top sealing plate connecting member body 310 can be made of PP, PVC, ABS and other materials.

[0080] The plug-in portion is extended along the rear top sealing plate connector body 310 .

[0081] Specifically, the plug-in portion is extended on the rear top cover plate connector body 310 along the width direction of the container.

[0082] The plug-in portion is used for plugging in the door curtain assembly 400 .

[0083] When there are multiple inserting parts, the multiple inserting parts are arranged at intervals along the direction from the inner top plate 100 to the rear frame door lintel 200 .

[0084] The rear top sealing plate connector body 310 and the plug-in portion are an integrally formed structure.

[0085] The door curtain assembly 400 is plugged into the plug-in portion, so that the door curtain assembly 400 is conveniently and stably installed on the rear top sealing plate connector body 310 .

[0086] In some embodiments of the present application, the door curtain assembly 400 includes a door curtain track 410 .

[0087] In order to realize the convenient installation of the door curtain track 410 relative to the rear top sealing plate connector body 310, the plug-in portion includes a track plug-in portion 321. The track plug-in portion 321 is extended and formed on one side of the rear top sealing plate connector body 310 close to the inner side of the container.

[0088] The rail plug-in portion 321 and the rear top sealing plate connector body 310 are an integrally formed structure.

[0089] Specifically, the rail plug-in portion 321 may be a first plug-in groove formed by two oppositely disposed L-shaped structures.

[0090] The first insertion groove is formed on the rear top cover plate connector body 310 and extends along the width direction of the container.

[0091] The door curtain rail 410 is inserted into the first insertion groove from the end of the first insertion groove.

[0092] like Fig.16 As shown, in some other embodiments of the present application, the door curtain track 410 and the rear top sealing plate connecting member body 310 adopt an integrally formed structure.

[0093] Specifically, the door curtain track 410 is formed on a side of the rear top sealing plate connecting member body 310 close to the outside of the container.

[0094] In this case, the door curtain track 410 does not protrude outside the rear top sealing plate connector body 310, thereby reducing the space occupied inside the container and avoiding collisions during loading and unloading of goods, which may cause damage to the rear top sealing plate connector.

[0095] In some embodiments of the present application, the door curtain assembly 400 includes a reinforced back panel 420 .

[0096] In order to realize the convenient installation of the reinforcing back plate 420 relative to the rear top sealing plate connector body 310, the plug-in portion includes a reinforcing back plate plug-in portion 322. The reinforcing back plate plug-in portion 322 is extended and formed on one side of the rear top sealing plate connector body 310 close to the outside of the container.

[0097] The reinforced back plate plug-in portion 322 and the rear top sealing plate connector body 310 are an integrally formed structure.

[0098] Specifically, the reinforced backplane plug-in portion 322 may be a second plug-in slot formed by two oppositely disposed L-shaped structures.

[0099] The second insertion groove is formed on the rear top cover plate connector body 310 and extends along the width direction of the container.

[0100] The reinforcing back plate 420 is inserted into the second inserting slot from the end of the second inserting slot.

[0101] In some embodiments of the present application, the rail plug-in portion 321, the reinforced back panel plug-in portion 322 and the rear top sealing plate connector body 310 are an integrally formed structure, which can replace the door curtain assembly 400 and be connected to the rear top sealing plate connector body 310 by bonding or the like, thereby reducing the installation procedure and assembly time, while ensuring a stable connection between the door curtain assembly 400 and the rear top sealing plate connector body 310.

[0102] In some embodiments of the present application, a wave portion 311 is formed along the surface of the rear top cover plate connector body 310 close to the outside of the container. The wave portion 311 is used to increase the connection strength between the rear top cover plate connector body 310 and the foam insulation layer 500.

[0103] In some embodiments of the present application, a concave-convex portion 312 is formed along the surface of the rear top cover plate connector body 310 close to the inner side of the container. The concave-convex portion 312 is used to increase the anti-slip property of the rear top cover plate connector body 310.

[0104] In some embodiments of the present application, a reinforcing rib 313 is formed extending along the surface of the rear top sealing plate connector body 310 close to the outside of the container, and the reinforcing rib 313 is used to increase the structural strength of the rear top sealing plate connector body 310.

[0105] Since the reinforcing ribs 313 extend into the foam insulation layer 500 , the connection strength between the rear top sealing plate connector body 310 and the foam insulation layer 500 can be enhanced.

[0106] The reinforcing rib 313 may also adopt various structural forms. Specifically, the reinforcing rib 313 may adopt an L-shaped structure.

[0107] In some embodiments of the present application, the rear top sealing plate connector further includes a cable groove 330. The number of the cable groove 330 is at least one.

[0108] The cable groove 330 is extended along the rear top sealing plate connector body 310 .

[0109] The cable groove 330 is an integrated structure with the rear top sealing plate connector body 310 , which increases the extrusion molding rate of the profile and increases the strength of the rear top sealing plate connector body 310 . The cable groove 330 is used for the extension setting of the cable 610 .

[0110] The cable groove 330 is extended along one side of the rear top sealing plate connector body 310 close to the outside of the container.

[0111] Specifically, the cable groove 330 is extended along one side of the rear top sealing plate connector body 310 close to the foam insulation layer 500 .

[0112] The cable 610 is extended along the cable groove 330 .

[0113] The cable groove 330 can ensure the standard routing of the cable 610, so as to prevent the cable 610 from being squeezed and deformed during the foaming process of the container; or, due to excessive pressure during foaming, it is easy to apply a large force on the cable 610, causing the cable to move and deviate from the original position, resulting in the cable 610 being pulled unsmoothly, making it difficult to connect and replace.

[0114] The cable groove 330 may be a closed groove 331 or a semi-closed groove 332 .

[0115] The closed groove 331 may have a circular ring shape, a triangular ring shape, a rectangular ring shape, or the like in cross section.

[0116] The semi-enclosed groove 332 may be formed of two oppositely disposed L-shaped structures.

[0117] The bent ends of the two L-shaped structures are arranged opposite to each other to form an opening portion of the semi-closed groove 332 , and the bent ends of the two L-shaped structures are used to prevent the cable 610 from falling therefrom.

[0118] In some embodiments of the present application, the cable 610 needs to first pass through the cable tube 620 , and the cable tube 620 passes through the semi-enclosed groove 332 .

[0119] In some other embodiments, the cable 610 groove may be an L-shaped semi-enclosed groove 332 .

[0120] In some embodiments of the present application, the rear top sealing plate connector further includes a plurality of auxiliary support portions 340. The auxiliary support is used for auxiliary support between the rear frame door lintel 200 and the rear top sealing plate connector body 310, and the plurality of auxiliary support portions 340 are arranged at intervals between the rear frame door lintel 200 and the rear top sealing plate connector body 310.

[0121] An auxiliary support plug-in portion 314 is formed on one side of the rear top cover plate connector body 310 close to the outside of the container. The lower end of the auxiliary support portion 340 is plugged into the auxiliary support plug-in portion 314 , and the upper end of the auxiliary support portion 340 abuts against the rear frame lintel 200 .

[0122] In some embodiments of the present application, the rear top sealing plate connecting member further includes a fresh-keeping groove 350 , and the fresh-keeping groove 350 is integrally formed with the rear top sealing plate connecting member body 310 .

[0123] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
