Description

Technical Field

[0001] This utility model belongs to the field of container technology, specifically, it relates to a bottom structure of a refrigerated container and a refrigerated container. Background Technology

[0002] Currently, in refrigerated containers, such as Figure 1 As shown, the floor is made of T-shaped aluminum profiles, which are widely used due to their low material consumption and high strength. However, the material itself is expensive, resulting in a high price for the enclosure and making it unsuitable for loading low-value-added fast-moving consumer goods.

[0003] Dry cargo containers are constructed using spliced ​​wooden flooring, offering good load-bearing capacity at a moderate price. The bottom structures of ordinary dry cargo containers and refrigerated containers differ. The floor of a dry cargo container is simply laid and fixed to floor beams, without any sealing requirements. In contrast, the bottom of a refrigerated container requires polyurethane foam filling. If the floor is not sealed, leakage and overflow of the polyurethane foam will occur, affecting the container's quality and contaminating the floor surface. In refrigerated containers, the floor needs to be connected as a single unit to address both load-bearing and sealing issues.

[0004] Therefore, developing a bottom structure for refrigerated containers and a connection structure for refrigerated containers that combines wooden flooring with the floor of refrigerated containers is a technical problem that urgently needs to be solved. This approach is cost-effective and can meet the load-bearing capacity requirements of refrigerated containers. Utility Model Content

[0005] The purpose of this utility model is to provide a bottom structure for a refrigerated container and a refrigerated container, so as to solve the problems of high cost of refrigerated container floor and load-bearing capacity if the wooden floor used in dry containers is adopted.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] In one aspect, this utility model proposes a bottom structure for a refrigerated container, comprising:

[0008] The floor, which comprises multiple floor units;

[0009] Container frame;

[0010] Floor connector for connecting adjacent floor units to form the floor, the floor connector comprising:

[0012] Fastening components for connecting the floor unit to the floor connection structure body;

[0013] A load-bearing part is inserted into the receiving part, and the load-bearing part is used to support the container base frame and the floor;

[0014] An insulation layer is provided, which fills the area formed by the floor and the container frame.

[0015] In some embodiments of this application, a corner seal is also included, which extends circumferentially along the floor and connects the floor to the front end and side end of the container.

[0016] In some embodiments of this application, multiple floor units are arranged adjacent to each other along the length of the refrigerated container, and the floor connecting portion extends along the width of the refrigerated container at the connection point of two adjacent floor units.

[0017] And / or, a plurality of the floor units are connected and arranged along the width direction of the refrigerated container.

[0018] In some embodiments of this application, an auxiliary load-bearing part is also included, which extends along the width direction of the refrigerated container and is disposed between the floor unit and the container frame, for auxiliary support of the floor unit.

[0019] In some embodiments of this application, one end of the auxiliary load-bearing part abuts against the floor; the auxiliary load-bearing part is connected to the floor unit via an auxiliary fastening assembly, and the other end of the auxiliary load-bearing part is connected to the container frame via the auxiliary connecting part.

[0020] In some embodiments of this application, the floor connection structure body is an integral structure;

[0021] The support portion is a support plane formed on the floor connection structure body;

[0022] The receiving part is a receiving cavity formed by the floor connecting structure body. The receiving cavity has an open end. One end of the load-bearing part is inserted into the receiving cavity from the open end, and the other end of the load-bearing part is supported at the container base frame.

[0023] In some embodiments of this application, the floor connection structure body further includes two extensions, which are respectively formed on both sides of the support. The extensions extend from the support in a direction away from the connection point of the two adjacent floors into the insulation layer formed between the floor unit and the container frame.

[0024] In some embodiments of this application, the floor connection portion further includes a sealing portion, which extends between the floor unit and the support portion; the sealing portion extends along the contact surface of the two floor units.

[0025] In some embodiments of this application, a bottom crossbeam is formed on the container frame, a cover plate is used to cover the bottom crossbeam, and the load-bearing part is disposed on the bottom crossbeam through the cover plate.

[0026] In another aspect, this utility model also proposes a refrigerated container, including the refrigerated container bottom structure described in any of the above claims.

[0027] Compared with the prior art, the advantages and positive effects of this utility model are:

[0028] By providing floor connecting parts between floor units, multiple floor units can be connected to form a floor. The floor connecting structure body is located at the lower part of the connection between adjacent floor units to support the adjacent floor units. By providing fastening components, the floor units are connected to the floor connecting structure body. By providing load-bearing parts, the floor units are supported between the container chassis. The floor formed by connecting in the above manner is inexpensive and can meet the load-bearing capacity requirements of refrigerated containers. Since the floor connecting structure body is located in the insulation layer, the stability of the bond between the insulation layer and the floor can be improved, thereby further ensuring the support strength of the bottom structure of the refrigerated container.

[0075] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0076] In some embodiments of this application, a refrigerated container is provided, which includes a bottom structure that can ensure stable support performance of the bottom structure at a low cost.

[0077] like Figures 2 to 8 As shown, the bottom structure of a refrigerated container includes a floor 100, a container frame 200, a floor connection 300, and an insulation layer 400.

[0078] like Figure 2 , Figure 4 , Figure 5 As shown, the floor 100 and the container frame 200 are arranged parallel to each other, with the container frame 200 located below the floor 100. The insulation layer 400 is filled between the floor 100 and the container frame 200. The insulation layer 400 fills the area enclosed between the floor 100 and the container frame 200.

[0079] To reduce the cost of floor 100, floor 100 includes multiple floor units 110.

[0080] In some embodiments of this application, a plurality of floor units 110 are spaced apart along the length of the refrigerated container, and a floor connecting portion 300 extends along the width of the refrigerated container and is disposed at the connection between two adjacent floor units 110.

[0081] Floor unit 110 can be made of wood flooring, which is inexpensive.

[0082] The floor connector 300 is used for connecting two adjacent floor units 110.

[0083] Since the floor unit 110 is made of wood, and the floor 100 is formed by connecting the floor connecting parts 300, the floor 100 is made inexpensive.

[0084] In some embodiments of this application, in order to ensure that adjacent floor units 110 are connected by floor connection portion 300, a sealing portion is provided between them. The sealing portion extends between the floor unit 110 and the support portion 300, and extends along the contact surface of the floor unit 110.

[0085] Specifically, such as Figure 8 As shown, the sealing part can be made of sealant 710. Along the length of the refrigerated container, sealant 710 is applied between the ends of two adjacent floor units 110. When the two floor units 110 are in contact, the sealant 710 extends along the contact surface between the two floor units 110.

[0086] A sealant 710 is applied to the contact surface between the floor unit 110 and the floor connection portion 300. When the floor unit 110 and the floor connection portion 300 are in contact, the sealant 710 extends along the contact surfaces, thereby achieving a seal between the two floor units 110 and between the floor unit 110 and the floor connection portion 300. This provides a sealed cavity for the filling of the insulation layer 400.

[0087] Since the container is a refrigerated container, the floor connection part 300 needs to connect two adjacent floor units 110 while also preventing heat conduction between the floor 100 and the container frame 200.

[0088] In some embodiments of this application, such as Figure 3 As shown, the floor connection part 300 includes a floor connection structure body 310, a fastening component 320, and a load-bearing part 330.

[0089] Fastening assembly 320 is used to connect floor connection structure body 310 to floor unit 110.

[0090] like Figure 4 , Figure 5 As shown, one end of the load-bearing part 330 is abutted against the floor unit 110 via the floor connection structure body 310. The other end of the load-bearing part 330 is supported and connected to the container base frame 200.

[0091] The weight borne by the floor 100 is transferred to the container frame 200 through the load-bearing part 330. Since the load-bearing part 330 is connected to both the floor 100 and the container frame 200, it needs to be made of a material with poor thermal conductivity to avoid thermal bridging between the floor 100 and the container frame 200, which would cause heat transfer between them.

[0092] In some embodiments of this application, such as Figure 3 As shown, a support portion 311 and a receiving portion 312 are formed on the floor connection structure body 310.

[0093] The support 311 is disposed below the connection between two adjacent floor units 110 and is used to support the two adjacent floor units 110.

[0094] Specifically, the support 311 can be a support plane formed on the floor connection structure body 310. The support plane abuts against the lower surfaces of two adjacent floor units 110.

[0095] The receiving part 312 is used to receive the load-bearing part 330, so that the load-bearing part 330 can support the floor 100 through the floor connection structure body 310.

[0096] The receiving part 312 is a receiving cavity formed by the floor connection structure body 310.

[0097] Specifically, one end of the load-bearing part 330 is inserted into the receiving cavity, and the other end of the load-bearing part 330 is supported and connected to the container base frame 200.

[0098] Specifically, the load-bearing part 330 can be made of non-metallic materials. For example, the load-bearing part 330 can be made of PE blocks.

[0099] In some embodiments of this application, the floor connection structure body 310 is an integral structure. The support portion 311 is a protrusion formed on the floor connection structure body 310 in the direction toward the floor unit 110, and the support plane is formed on the side of the protrusion near the floor 100.

[0100] In some embodiments of this application, the receiving cavity is formed with an open end 3121, and the load-bearing part 330 can be inserted into the receiving cavity from the open end 3121.

[0101] The receiving cavity is formed on the side of the protrusion away from the floor by 100.

[0102] This enables the plug-in connection between the load-bearing part 330 and the floor connection structure body 310.

[0103] Specifically, such as Figure 2 , Figure 4 As shown, a clearance portion 331 is formed at the end of the load-bearing portion 330. When the load-bearing portion 330 is inserted into the receiving cavity, the clearance portion 331 is used to prevent interference between the load-bearing portion 330 and the floor connection structure body 310.

[0104] Specifically, the clearance portion 331 is formed at the two ends of the load-bearing portion 330, thereby avoiding interference between the two ends of the load-bearing portion 330 and the floor connection structure body 310.

[0105] In some embodiments of this application, the floor connection structure body 310 further includes two extensions 313. The two extensions 313 are respectively formed on both sides of the support 311. The extensions 313 extend from the support 311 in a direction away from the connection point of the floor unit 110 into the insulation layer 400.

[0106] Since the extension 313 extends into the insulation layer 400, it can serve to fix the insulation layer 400.

[0107] Specifically, the insulation layer 400 is a polyurethane foam filling the area formed by the floor 100 and the container frame 200. The extension 313 serves to fix the polyurethane foam.

[0108] Specifically, the cross-sectional shape of the floor connection structure body 310 is “Ω”.

[0109] Specifically, the floor connection structure body 310 is formed by bending or extrusion.

[0110] In some embodiments of this application, two extensions 313 are respectively connected to the two ends of the protrusion, and an inlet 314 is formed at the connection between the extension 313 and the protrusion. During the process of inserting the load-bearing part 330 into the receiving cavity, the inlet 314 is used to guide the load-bearing part 330.

[0111] Specifically, the inlet portion 314 is an arc shape formed at the connection between the extension portion 313 and the protrusion portion.

[0112] In some embodiments of this application, the floor connection portion 300 further includes a connection portion 340. The connection portion 340 is used for the connection between the load-bearing portion 330 and the container base frame 200.

[0113] Specifically, such as Figure 2As shown, the connecting part 340 can be made of angle iron 341 and bolts 342. The two sides of the angle iron 341 abut against the load-bearing part 330 and the container base frame 200, respectively. The angle iron 341 is connected to the connecting part 340 by bolts 342.

[0114] In some embodiments of this application, the floor connection portion 300 further includes an auxiliary load-bearing portion 350. The auxiliary load-bearing portion 350 is used to provide auxiliary support for the floor unit 110. The auxiliary load-bearing portion 350 is disposed between the floor 100 and the container frame 200.

[0115] The auxiliary load-bearing part 350 is connected to the floor unit 110 via the auxiliary fastening assembly 370.

[0116] The auxiliary load-bearing part 350 is connected to the container base frame 200 via the auxiliary connecting part 360.

[0117] In some embodiments of this application, a bottom crossbeam 210 is formed on the container chassis 200. The bottom crossbeam 210 on the container chassis 200 has high strength, and the floor 100 can act on the bottom crossbeam 210 through the load-bearing part 330, thereby improving the stress condition of the chassis 200.

[0118] Specifically, a cover plate 220 covers the bottom crossbeam 210, and the load-bearing part 350 is installed on the bottom crossbeam 210 through the cover plate 220.

[0119] In some embodiments of this application, the bottom structure of the refrigerated container also includes a corner seal, which extends circumferentially along the floor 100 and connects the floor 100 with the front end 610 and the side end of the container.

[0120] Specifically, such as Figure 4 , Figure 5 , Figure 6 As shown, the corner seal includes a front sealing plate 510. The floor 100 is connected to the front end 610 of the container via the front sealing plate 510.

[0121] To ensure a sealed connection between the front sealing plate 510 and the front end of the container 610, sealant 710 is also required at the contact surface between the two. When the front sealing plate 510 and the front end of the container 610 are in contact, the sealant 710 extends along the contact surface between the two.

[0122] Specifically, such as Figure 4 , Figure 5 , Figure 6 As shown, the corner seal also includes a rear sealing plate 520. The rear sealing plate 520 is used to seal the end of the floor unit 110 within the floor 100 near the door end.

[0123] Specifically, such as Figure 5As shown, the corner seal also includes a corner side seal 530. The floor 100 is connected to the side end of the container via the corner side seal 530.

[0124] In some other embodiments of this application, a plurality of floor units 110 are connected and arranged along the width direction of the refrigerated container.

[0125] Specifically, such as Figure 8 As shown, a connecting groove 111 is formed at the end of the floor unit 110 along the width direction of the refrigerated container, and a back panel 112 is attached to the connecting groove 111 of two adjacent floor units 110 by sealing tape 720.

[0126] Specifically, sealant 710 is applied to the ends of adjacent floor units 110. When the ends of adjacent floor units 110 are abutting each other, the sealant 710 flows along the ends of the two floor units 110, thereby covering the ends of the floor units 110 and achieving adhesion of the two floor units 110.

[0127] By attaching sealing tape 720 between the connecting groove 111 and the back panel 112, the connection between the ends of two adjacent floor units 110 along the width direction of the refrigerated container is achieved, and at the same time, sealant 710 is applied between the ends of the two floor units 110 along the width direction of the refrigerated container, thus sealing the connection and preventing the insulation layer 400 from overflowing at the connection.

[0128] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0129] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0130] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
