Abstract

This utility model discloses a box structure with inner side panel reinforcing ribs. The outer layer of the box is welded from outer side panels, and the inner layer is spliced ​​from inner side panels. Novel reinforcing ribs are provided on the outer surfaces of the inner side panels. E-Track brackets are connected to the inner side panels via these ribs. E-Track pressure plates of the E-Track brackets clamp and rivet the ends of the inner side panels. The inner side panels are connected to each other via E-Track brackets. The inner side panels at the junctions are welded to the box body. A foam layer is filled between the inner and outer layers of the box, and the novel reinforcing ribs are hooked into the foam layer. This utility model uses novel reinforcing ribs formed by die-casting aluminum profiles to connect the inner side panels and E-Track brackets into a single unit, eliminating the need to connect outer side panels. This effectively avoids thermal bridging, improves the box's insulation performance, reduces refrigeration energy consumption, strengthens the overall structure, and enhances stability. The hook design with the foam layer effectively improves delamination.

Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated containers, and more specifically, to a box body structure with inner side plate reinforcing ribs. Background Art

[0002] Refrigerated containers in the Japanese and Korean markets generally have a demand for E-Track. Usually, the E-Track is installed by riveting on the E-Track bracket 4, and the E-Track bracket 4 is connected to the outer side plate 1 through conventional reinforcing ribs 7 to maintain a certain connection strength. As shown in the attached Figure 4 and 5 The box body is a double-layer structure with an inner and outer layer. The outer layer is assembled by the outer side plate 1, and the inner layer is spliced by the inner side plate 2. A number of conventional reinforcing ribs 7 are welded on the inner side surface of the outer side plate 1 in an orderly manner in the horizontal and vertical directions. The inner side plate 2 is clamped and fixed on the E-Track pressing plate 3 of the E-Track bracket 4. The E-Track bracket 4 is first connected to the conventional reinforcing rib 7 through the E-Track bracket 6, and then connected to the outer side plate 1 with the help of the conventional reinforcing rib 7 to form a complete structure.

[0003] However, the formation of this structure also results in a thermal bridge between the outer side plate 1 and the inner side plate 2, transferring the heat inside the box to the outside of the box, causing a layer of water vapor to adhere to the outside of the box, and causing certain damage to the box body. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a box body structure with inner side plate reinforcing ribs to solve one or more of the above problems.

A foaming layer is filled between the inner layer and the outer layer of the box body, and the new type of reinforcing rib is hooked in the foaming layer.

[0007] Further, the cross-section of the new type of reinforcing rib connected to the inner side plate is a king-shaped structure, and the outer ends of the new type of reinforcing rib connected to the inner side plate are lengthened and the two wings are folded inward.

[0008] Furthermore, the outer side of the E-Track bracket is also provided with the new type of reinforcing rib.

The end of the inner side plate is clamped in the clamping opening of the E-Track pressure plate, and the E-Track bracket and the inner side plate are also connected by rivets.

[0011] Furthermore, all of the novel reinforcing ribs are hooked into the foam layer.

[0019] Example:

[0020] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0021] A box structure with two reinforcing ribs on the inner side plate, such as Figures 1-3 As shown, the main structure of the container is a conventional refrigerated container design. The container is divided into an inner layer and an outer layer. The outer layer is welded together from several outer side panels 1, and the inner layer is spliced ​​together from several inner side panels 2. The inner layer is sized based on the structure of the outer layer. The inner side panels 2 have more rubber outer side panels 1 and a smaller area. There are butt joints between the inner side panels 2, which are achieved through welding or riveting. The inner side panels 2 at the four corners are fixed to the container body by welding or other means. A foam layer is filled between the inner and outer layers of the container. There are two types of new reinforcing ribs 5: one type is set on the outer side of the inner side panel 2, and the other type is set directly opposite the E-Track bracket 4. The former has a king-shaped cross-section, and the latter has an I-shaped cross-section. Both are designed with an extended and inwardly folded edge at one end of the outer side, and both form a hook structure with the foam layer. That is, the two types of new reinforcing ribs 5 hook into the foam layer to strengthen the connection structure. The outer side of the inner side plate 2 is connected to a new type of reinforcing rib 5. This new type of reinforcing rib 5 is welded to the inner side plate 2, mainly to enhance the stability of the inner side plate 2 structure. The new type of reinforcing rib 5 connected to the E-Track bracket 4 is indirectly connected to the inner side plate 2 through the foam layer, and different inner side plates 2 are riveted together through E-Track pressure plates provided at both ends of the welded E-Track bracket 4 to complete a closed connection relationship. Both ends of the E-Track bracket 4 are provided with E-Track pressure plates 3. The E-Track pressure plates 3 are set inwardly out of the E-Track bracket 4. The E-Track pressure plates 3 have clamping openings corresponding to the relevant inner side plates 2. The clamping ends of the E-Track pressure plates 3 and the mating inner side plates 2 are provided with aligned riveting holes. The end edge of this part of the inner side plate 2 is clamped in the clamping opening of the E-Track pressure plates 3, and rivets are added to consolidate the connection.

[0022] However, the installation sequence is different. The inner side plate 2 and the E-Track bracket 4 are pre-connected with rivets to form a preliminary structure. Subsequently, the new reinforcing rib 5 is welded to the inner side plate 2 to enhance structural stability. Because both the new reinforcing rib 5 and the E-Track bracket 4 are made of aluminum, they can be welded using aluminum wire, forming a single integrated structure. This eliminates the need for additional E-Track brackets 6 (e.g., ...). Figures 4-5 (As shown). After the outer end of the inner side plate 2 is foamed, the new reinforcing rib 5 has a foam-hooking function, and basically no delamination occurs during the entire use process. There is no direct rigid connection between the inner and outer side plates 1, so there will be no thermal bridging effect and no water vapor is generated.

[0023] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
