[0058] In some embodiments of the present application, a thermal insulation container is involved. As shown in the drawings, the thermal insulation container includes a floor 110 and a chassis 120. A foaming layer 130 is formed between the floor 110 and the chassis 120. The foaming layer 130 fills the area formed between the floor 110 and the chassis 120. Figure 2

[0059] In some embodiments of the present application, a floor reinforcing rib is also involved, which is arranged in the foaming layer 130 for reinforcing the floor 110. It helps to increase the overall rigidity between the floor 110 and the foaming layer 130, and avoid delamination between the floor 110 and the foaming layer 130.

[0060] At the same time, in the foaming layer 130, in order to achieve auxiliary support for the floor and separation of the foaming layer, a non-metallic support part 140 is usually arranged along the width direction of the floor 110.

[0061] In the prior art, by arranging an angle iron or an angle aluminum along the width direction of the floor 110, the non-metallic support part 140 is abutted at the vertical edge of the angle iron or the angle aluminum, and the non-metallic support part 140 is connected to the angle iron or the angle aluminum by self-tapping screws, so as to realize the installation of the non-metallic support part. This installation method requires many types of components, and is time-consuming and laborious.

[0062] Therefore, in some embodiments of the present application, as shown in the drawings, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 The floor reinforcing rib includes a reinforcing rib body 200, a anti-disengagement part 300 and a connecting part 400.

[0063] The reinforcing rib body 200 is connected with the floor 110, and is used to realize the structural strength of the floor 110.

[0064] By connecting the connecting part 400 on the reinforcing rib body 200, the connecting part 400 extends in the foaming layer 130, and is used to increase the connection strength between the floor 110 and the foaming layer 130. ​

[0065] As shown in Figure 7 the reinforcing rib body 200, a non-metallic support portion mounting cavity 210 is formed in the reinforcing rib body 200 for mounting the non-metallic support portion 140. By forming an anti-falling portion 300 in the non-metallic support portion mounting cavity 210, the non-metallic support portion 140 is limited in the non-metallic support portion mounting cavity 210, thereby preventing the non-metallic support portion 140 from falling out of the non-metallic support portion mounting cavity 210.

[0066] In some embodiments of the present application, as shown in Figure 7 the reinforcing rib body 200 includes a top edge 220 and two standing edges 230. The two standing edges 230 are respectively connected at both ends of the top edge 220. The two standing edges 230 are arranged in the same direction along the top edge 220. The two standing edges 230 and the top edge 220 form the non-metallic support portion mounting cavity 210.

[0067] Specifically, the non-metallic support portion mounting cavity 210 formed by the two standing edges 230 and the top edge 220 is formed with an open end 240. The non-metallic support portion 140 is mounted into the non-metallic support portion mounting cavity 210 from the open end 240.

[0068] In some embodiments of the present application, the anti-falling portion 300 is formed on the standing edge 230 as a protruding portion near the non-metallic support portion mounting cavity 210. The protruding portion exerts a force on the non-metallic support portion 140 to prevent the non-metallic support portion 140 from falling out of the non-metallic support portion mounting cavity 210.

[0069] In some embodiments of the present application, as shown in Figure 3 the protruding portion is arranged protruding from the standing edge 230 to the side of the non-metallic support portion mounting cavity 210. A guide surface 310 is formed on the protruding portion. The guide surface 310 is formed on the side of the protruding portion near the non-metallic support portion mounting cavity 210.

[0070] Specifically, the guide surface 310 is formed on the side of the protruding portion near the open end 240.

[0071] During the installation of the non-metallic support portion 140, the non-metallic support portion 140 is moved along the guide surface 310 from the open end 240 to be mounted into the non-metallic support portion mounting cavity 210.

[0072] Specifically, the protruding portion can be formed in a bent shape with a cross section protruding towards the inside of the non-metallic support portion mounting cavity 210. The bent surface near the open end 240 is the guide surface 310. The surface extending in connection with the guide surface 310 is a recovery surface 320, which is bent towards the side away from the non-metallic support portion mounting cavity 210.

[0073] Specifically, the number of the protruding part can be one, and the protruding part is arranged on one side wall of the non-metallic support part mounting cavity 210.

[0074] Specifically, the number of the protruding part can also be multiple. Taking two protruding parts as an example, the two protruding parts are arranged on two side walls of the non-metallic support part mounting cavity 210. Specifically, the two protruding parts are arranged oppositely.

[0075] In the process of inserting the non-metallic support part 140 into the non-metallic support part mounting cavity 210 from the opening end 240, the non-metallic support part 140 enters and moves in the non-metallic support part mounting cavity 210 along the guide surface 310, and pushes the protruding part to elastically deform, so that the non-metallic support part 140 is inserted into the non-metallic support part mounting cavity 210.

[0076] In order to enable the non-metallic support part 140 to be stably mounted in the non-metallic support part mounting cavity 210, and in the state that the non-metallic support part 140 is mounted in the non-metallic support part mounting cavity 210, the reinforcing rib body 200 is in a force-free state, so as to guarantee the service life of the reinforcing rib body 200, the non-metallic support part 140 and the non-metallic support part mounting cavity 210 are profiled.

[0077] In some other embodiments of the present application, as shown in Figure 5 、 Figure 6 、 Figure 7 The protruding part is a boss 330 formed on the vertical edge 230 close to the opening end 240, and the boss 330 is arranged towards the non-metallic support part mounting cavity 210.

[0078] Specifically, taking the number of the boss 330 as two as an example,

[0079] Specifically, two bosses 330 are formed at the opening end 240 of the non-metallic support part mounting cavity 210. In this state, the non-metallic support part 140 cannot be inserted into the non-metallic support part mounting cavity 210 from the opening end 240. In this state, the non-metallic support part 140 is inserted into the non-metallic support part mounting cavity 210 from the end of the reinforcing rib body 200.

[0080] Correspondingly, the non-metallic support part 140 is formed with a first groove 141 corresponding to the boss 330. The boss 330 is inserted into the first groove 141. Thus, the non-metallic support part mounting cavity 210 limits the non-metallic support part 140.

[0081] In some other embodiments of the present application, as shown in Figure 8 、 Figure 9As shown, the protrusion can also extend along the bottom end of the opening end 240 towards the non-metallic support portion mounting cavity 210. A second groove 142 is formed on the non-metallic support portion 140 corresponding to the position of the protrusion 340.

[0082] Specifically, two protrusions 340 are formed at the opening end 240 of the non-metallic support portion mounting cavity 210. In this state, the non-metallic support portion 140 cannot be inserted into the non-metallic support portion mounting cavity 210 from the opening end 240. In this state, the non-metallic support portion 140 is inserted into the non-metallic support portion mounting cavity 210 from the end of the reinforcing rib body 200.

[0083] Specifically, two protrusions 340 are formed at the opening end 240 of the non-metallic support portion mounting cavity 210. In this state, the non-metallic support portion 140 cannot be inserted into the non-metallic support portion mounting cavity 210 from the opening end 240. In this state, the non-metallic support portion 140 is inserted into the non-metallic support portion mounting cavity 210 from the end of the reinforcing rib body 200.

[0084] In some embodiments of the present application, the connecting portion 400 is a flange extending away from the non-metallic support portion mounting cavity 210 from the standing edge 230.

[0085] Specifically, as shown, Figure 10 A wave surface 410 is formed along the surface of the connecting portion 400 adjacent to the foamed layer 130. The wave surface 410 is used to increase the bonding force between the connecting portion 400 and the foamed layer 130. It avoids delamination between the foamed layer 130 and the floor 110.

[0086] In some other embodiments, as shown, Figure 11 The non-metallic support portion 140 is connected to the reinforcing rib body 200 by the fastener 350.

[0087] Specifically, the fastener 350 can adopt the form of a self-tapping screw.

[0088] Specifically, the fastener 350 is connected to the non-metallic support portion 140 through the standing edge 230.

[0089] The fastener 350 connection method can reduce the need for angle steel and other structures for arranging the non-metallic support portion 140. The non-metallic support portion 140 is directly connected to the reinforcing rib body 200 by the fastener 350.

[0090] Specifically, the non-metallic support portion 140 can be made of PE blocks, hardwood, high-density foam blocks, etc.

[0091] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0092] The above merely is the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
