In the following, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the utility model and do not limit the utility model.

Fig. 1 and 2 show a first container chassis 100 of a preferred embodiment of the utility model. The first container chassis 100 can bundle goods of a specific weight and can provide a large bundling force for bundling the goods.

Specifically, the first container chassis 100 includes at least two floors, two of which (the first floor 101 and the second floor 102) are spaced apart. Thus, there is a space between adjacent floor panels. The first container chassis 100 further comprises a first bottom beam 103, a first guide rail 110 and a first connector 130, the first bottom beam 103 being located below the at least two floors for supporting the at least two floors. The floor and the first bottom cross member 103 may be vertically arranged so that the first bottom cross member 103 can stably support the floor.

The first guide rail 110 is located between the first floor panel 101 and the second floor panel 102. The floor may be constructed as an aluminum floor. The first guide rail 110 is connected to the first floor 101 by welding, and the first guide rail 110 is also connected to the second floor 102 by welding. Thereby, the coupling strength between the first guide rail 110 and the floor is improved. Preferably, the first guide rail 110 and the first floor panel 101 are continuously welded to ensure waterproofness and durability between the first guide rail 110 and the first floor panel 101. The first guide rail 110 and the second floor 102 are continuously welded to ensure waterproofness and durability between the first guide rail 110 and the second floor 102. Thus, the first rail 110 and the floor may be integrated after welding. When a specific force is applied, the first guide rail 110 and the floor are stressed integrally, so that the stress requirements of different bearing strengths in various directions can be met.

The first connecting member 130 may connect the first rail 110 and the first bottom cross member 103 together to further improve the connection strength of the first rail 110. The first rail 110 has a first coupling groove 111, and the first link 130 couples the first coupling groove 111 and the first floor cross member 103. This can further improve the strength of connection between the first rail 110 and the first floor cross member 103. The first guide rail 110 is not easily broken and separated from the floor, and the first guide rail 110 is also not easily broken and separated from the first bottom cross member 103, thereby providing a large binding force.

The first guide rail 110 also has a first binding groove 112, and the first binding groove 112 is used for binding the goods. The first lashing slot 112 may be connected to the goods by a lashing bar. The first binding slot 112 and the binding bars are attached in a manner similar to the attachment of the prior binding slots and binding bars. The first bundling slot 112 may include a flat portion and a string portion, and the flat portion and the string portion communicate with each other in a height direction of the first container chassis 100. The dimension of the flat portion in the width direction of the first rail 110 is larger than the dimension of the linear portion. The bundling rod comprises a main body part and an end part vertically connected with the main body part, and the length direction of the main body part is approximately parallel to the height direction of the container underframe. The end portion may be inserted into the flat portion through the linear portion and may be rotatable to engage with the linear portion. Thereby coupling the first banding groove 112 and the banding bar together.

Alternatively, the first connecting slot 111 and the first bundling slot 112 may correspond in a height direction of the first container chassis 100. Therefore, stress of the first guide rail 110 can be concentrated, and the structural strength of the first guide rail 110 is improved.

Thus, the first container underframe 100 provided by the utility model has the advantages that the floor and the first guide rail 110 are connected together in a welding mode, and the waterproofness is high. The first container underframe 100 can meet the binding of goods with special weight or special structures, can provide binding force for goods with the maximum strength higher than that required by other common binding positions, meets the high-strength bearing binding force, can meet the characteristic container with special space requirements, avoids that the first binding groove 112 cannot be arranged due to the lack of a side plate or a top plate, and also avoids that goods cannot be well bound due to the fact that the side plate or the top plate cannot provide enough binding bearing force.

Further, the first connecting groove 111 has an opening that can be opened toward the first bottom beam 103. The first connecting member 130 may extend through the opening to connect with the first bottom rail 103, ensuring the overall structural strength of the first rail 110. The first connecting groove 111 is also open at an end in the longitudinal direction of the first rail 110. Thereby, the first connecting member 130 can be made to enter the first connecting groove 111 through the open end of the first connecting groove 111, and then be connected to the first bottom beam 103.

The first connecting groove 111 has a first opening 113 and a second opening 114, and the first opening 113 opens in the direction of the first floor cross member 103. A portion of the first connecting member 130 is located in the first connecting slot 111, and another portion of the first connecting member 130 extends out of the first opening 113 to connect with the first bottom beam 103. The second opening 114 is located at an end of the first connection groove 111 in the length direction of the first guide rail 110, and the second opening 114 is opened such that the end of the first connection groove 111 in the length direction of the first guide rail 110 is opened. The first link 130 enters the first link groove 111 through the second opening 114 at the end to be connected with the first guide rail 110.

The first connecting element 130 is designed as a screw having a head 131, a tail 132 and a shank 133. The bolts may be high strength standard size bolts. The standard thread code of the high-strength bolt is GB/T5782-. The bolts may be hex bolts, lag bolts or other standard forms of bolts. The rod 133 is connected to the head 131 and the tail 132 along both ends of the first container chassis 100, respectively. The dimension of the head 131 in the radial direction of the stem 133 is larger than the dimension of the stem 133. The head 131 of the bolt is connected to the first connecting groove 111, and the tail 132 of the bolt is connected to the first bottom cross member 103. Thus, the structure is simple, and the first guide rail 110 and the first bottom cross member 103 can be conveniently connected together.

To facilitate the connection with the bolt, the first connecting groove 111 includes a large-sized portion 115 and a small-sized portion 116, and the small-sized portion 116 is closer to the first floor cross member 103 than the large-sized portion 115. The large-sized portion 115 is located above the small-sized portion 116 in the height direction of the first container chassis 100. The head 131 of the bolt is located in the large-sized portion 115 and a portion of the shank 133 of the bolt is located in the small-sized portion 116. The small-sized portion 116 has the first opening 113 described above, and the small-sized portion 116 opens in the direction toward the first floor cross member 103. The shank 133 of the bolt can extend through the small-sized portion 116 to connect with the first floor beam 103.

The large-size portion 115 and the small-size portion 116 penetrate the first rail 110 in the length direction of the first rail 110, and ends of the large-size portion 115 and the small-size portion 116 in the length direction of the first rail 110 are open. The bolt may enter the first coupling groove 111 through the second opening 114 of the end of the first coupling groove 111 in the length direction of the first guide rail 110. In particular, the head 131 of the bolt may enter the large-sized portion 115 through an opening of an end of the large-sized portion 115 in the length direction of the first rail 110, and a portion of the shank 133 of the bolt may enter the small-sized portion 116 through an opening of an end of the small-sized portion 116 in the length direction of the first rail 110. The bolt is movable in the first coupling groove 111 in the length direction of the first guide rail 110.

The first bottom beam 103 has a connecting hole through which the shank 133 of the bolt can extend and the bolt is connected with the connecting hole of the first bottom beam 103. Alternatively, the tail portion 132 of the bolt may be connected to the first bottom rail 103 by a first nut 150. The coupling hole is located between the first nut 150 and the first rail 110. The first nut 150 is located on the other side of the first base beam 103 relative to the first rail 110. The tail portion 132 of the bolt may be threadably coupled to the first nut 150, and the first nut 150 may be a high strength nut. The standard thread code of the high-strength nut is GB/T5782-. The first nut 150 can lock the bolt to improve the coupling strength.

The first rail 110 is connected to the floor by welding. Preferably, the first guide rail 110 further includes a strap 117, and the strap 117 is connected to the floor by welding so that the first guide rail 110 is connected to the floor. The first rail 110 includes two strap plates 117 with a first strap slot 112 between the two strap plates 117. Thereby enabling the forces to be balanced. To avoid the first rail 110 interfering with the placement of the cargo, the upper surface of the strap 117 does not protrude above the upper surface 104 of the floor.

Further, the floor panel has a body portion 105 and a free end 106, the free end 106 being connected to the body portion 105. The free end of the first floor panel 101 and the free end of the second floor panel 102 are disposed opposite and spaced apart. The upper surface 107 of the free end 106 is lower than the upper surface of the body portion 105. The upper surface 107 of the free end 106 is lower than the upper surface of the body portion 105 in the height direction of the first container chassis 100.

The upper surface 107 of the free end 106 is lower than the upper surface of the strap 117 in the height direction of the first container chassis 100. The free end 106 is located below the strap 117 for supporting the strap 117. The lower surface of the strap 117 abuts the upper surface 107 of the free end 106. The strap 117 is connected to the free end 106 by welding, which improves the waterproof property. This increases the contact area between the floor panel and the strap 117, improves the strength of connection between the first rail 110 and the floor panel, and prevents the connection position between the first rail 110 and the floor panel from being broken.

Insulation material may be filled between the first floor 101 and the first bottom cross member 103, and insulation material may be filled between the second floor 102 and the first bottom cross member 103, so as to form the first container bottom frame 100 having insulation performance. A space is provided between the first floor panel 101 and the first bottom cross member 103, and a space is provided between the second floor panel 102 and the first bottom cross member 103 for accommodating insulation material.

In order to avoid the first guide rail 110 and the floor from bending downwards, the first container chassis 100 further comprises a first support 140, the first support 140 being located below the first guide rail 110 for supporting the first guide rail 110. The first support 140 may be configured as a block structure. The first supporting member 140 may be made of PE (Polyethylene) material to improve the heat insulation performance, so that the first rail 110 is connected to the first bottom cross member 103 in a heat insulation manner, and a heat bridge is prevented from being generated.

The floor further comprises a support 108, the support 108 being located below the free end 106. The free end 106 is connected with the first guide rail 110, and the supporting portion 108 is connected with the bottom of the free end 106 to support the free end 106, so as to ensure the structural strength of the connecting position of the first guide rail 110 and the free end 106 and avoid the connecting position of the floor and the first guide rail 110 from bending downwards and breaking. The longitudinal sectional shape of the support portion 108 may be configured in an inverted "T" shape, so that the contact area of the support portion 108 and the first support member 140 is large, and the stability of the support is improved. In the present embodiment, the longitudinal section is parallel to the height direction of the first container chassis 100. The first support 140 is also located below the support portion 108 for supporting the support portion 108. Thereby, the support portion 108 is prevented from bending downward, and the floor is prevented from sagging downward.

The bolts may first enter the first coupling grooves 111 through the openings of the ends of the first coupling grooves 111 to be coupled together in advance. The first support 140 and the first bottom cross member 103 are connected in advance, for example, the first support 140 and the first bottom cross member 103 are fixed together by foam molding.
