The invention provides a container which can be used in the cold chain transportation industry, in particular to a container which can be used for transporting fresh goods such as fruits and vegetables. As shown in fig. 2, the present invention also provides a side structure 100 of a container. The side structures 100 of the container may be located either on the sides of the container or at the ends of the container. As shown in fig. 3, the side structure 100 of the container includes an upper beam 111, a lower beam 112, an inner wall plate 113, an outer wall plate 114, and a column 130, and the upper beam 111 and the lower beam 112 are disposed opposite to each other in the height direction of the side structure 100. The inner wall panel 113 and the outer wall panel 114 are spaced apart. The inner wall plate 113 and the outer wall plate 114 are oppositely arranged in the thickness direction of the side structure 100. The thickness direction of the side structure 100 may be parallel to the width direction of the container or may be parallel to the length direction of the container.

The outer wall plate 114 is connected to the upper beam 111 and the lower beam 112. The top of the outer wall plate 114 is connected to the upper beam 111, and the bottom of the outer wall plate 114 is connected to the lower beam 112. The outer wall plate 114 may be connected to both the upper and lower beams 111 and 112 by welding. The side structure 100 further includes a thermal insulation material 115, the thermal insulation material 115 being located between the inner wall panel 113 and the outer wall panel 114. The insulating material 115 may be foam molded. To avoid the creation of internal and external thermal bridges of the side structure 100 of the container, the uprights 130 are positioned between the inner and outer panels 113, 114 and spaced apart from both the inner and outer panels 113, 114. A column 130 is provided in the space between the inner wall plate 113 and the outer wall plate 114. Column 130 is spaced from inner wall panel 113 and column 130 is not in contact with inner wall panel 113. The studs 130 are also spaced from the exterior wall panels 114 and the studs 130 are not in contact with the exterior wall panels 114. Column 130 is not directly connected to both inner wall panel 113 and outer wall panel 114. In this way, heat is not transferred to column 130 through outer wall panel 114 and to column 130 through inner wall panel 113, reducing the creation of internal and external thermal bridges of the container.

Insulation 115 is filled between the upright 130 and the inner wall plate 113, and insulation 115 is also filled between the upright 130 and the outer wall plate 114. In this way, the foaming quality is improved, the heat transfer of the side structure 100 is blocked, the heat insulation performance of the side structure 100 of the container is ensured, the heat leakage phenomenon caused by the generation of a heat bridge is avoided, and the phenomena of sinking or deformation and the like of the outer wall plate 114 and the inner wall plate 113 due to the foaming effect can be prevented.

Column 130 is connected to both upper beam 111 and lower beam 112 in an indirect manner. The top of column 130 is indirectly connected to upper beam 111 and the bottom of column 130 is indirectly connected to lower beam 112. The columns are not in direct contact with upper and lower beams 111 and 112, heat is indirectly transferred to column 130 through upper beam 111, and heat is indirectly transferred to column 130 through lower beam 112. The heat of the exterior wall panels 114 may be separated from the columns 130 by insulation 115, and the heat of the exterior wall panels 114 is not transferred to the interior of the container through the columns 130. The heat of the inner wall panel 113 may be separated from the column 130 by the insulation 115, and the heat of the inner wall panel 113 is not transferred to the outside of the container through the column 130. Heat is not transferred to the upright 130 through the outer wall plate 114 and the inner wall plate 113, so that the contact area of the upright 130 is reduced, particularly, the contact area of the upright 130 and the external environment is reduced, the heat loss is reduced, and the generation of a heat bridge is reduced.

Side structure 100 also includes upper anchor 140, upper anchor 140 being used to connect upright 130 with upper beam 111. The upper fixing member 140 is located between the inner wall plate 113 and the upper beam 111. The upper fixing member 140 is connected to the upper beam 111 along one side of the side structure 100 in the thickness direction. Alternatively, the upper fixture 140 may be coupled to the upper beam 111 by welding. The upper fixing member 140 is spaced apart from the inner wall plate 113 along the other side of the thickness direction of the side structure 100, and the upper fixing member 140 is not in contact with the inner wall plate 113. Heat is transferred to the upper fixture 140 through the upper beam 111.

Alternatively, the top of the outer wall panel 114 is located laterally of the upper beam 111 in the thickness direction of the side structure 100 and is connected to the upper beam 111. A portion of the outer wall panel 114 is located between the upper beam 111 and the inner wall panel 113. The bottom of the upper fixture 140 in the height direction of the side structure 100 may be in contact with the exterior wall panel 114. In an alternative embodiment, the bottom of the upper fixture 140 may be welded to the outer wall panel 114 to enhance the strength of the connection.

The top of the column 130 in the height direction of the side structure 100 may be connected to the upper beam 111 by an upper fixing member 140. Heat may be transferred to the top of column 130 through upper fixture 140. Thus, the column 130 is not in direct contact with the upper beam 111, and heat is indirectly transferred to the column 130 through the upper fixture 140, thereby reducing the occurrence of a thermal bridge phenomenon. Further, as shown in fig. 6, the upper fixture 140 has a substantially U-shaped cross-section. Thus, the top of column 130 is connected to upper beam 111 in point-to-face contact via upper mount 140. In this embodiment, the cross section is perpendicular to the height direction of the side structure 100.

Specifically, the upper fixture 140 includes two upper beam fixing sections, a column fixing section 143 for connecting the two upper beam fixing sections, the two upper beam fixing sections (the first upper beam fixing section 141 and the second upper beam fixing section 142) being substantially perpendicular to the upper beam 111, the column fixing section 143 being substantially parallel to the upper beam 111. The U-shaped opening direction of the upper beam 111 fixing member is substantially directed toward the upper beam 111. The first upper beam fixing section 141 and the second upper beam fixing section 142 are connected to the upper beam 111, respectively.

The first and second upper beam fixing sections 141 and 142 each include first and second ends, and the first ends of the first and second upper beam fixing sections 141 and 142 are respectively connected with the upper beam 111 to reduce the contact area of the upper fixing sections with the upper beam 111 to reduce heat transfer. The second ends of the first upper beam fixing sections 141 and the second upper beam fixing sections 142 are respectively connected to the column fixing sections 143 to be formed as a unit. The first upper beam fixing section 141 and the second upper beam fixing section 142 are connected to the upper beam 111 in a point contact manner. The upper fixing member 140 and the upper beam 111 may form a closed space in a horizontal direction, and the heat insulating material 115 may be filled in the space between the upper fixing member 140 and the upper beam 111 to enhance heat insulating performance, reduce heat loss, and prevent the inner wall plate 113 from being depressed or deformed due to foaming.

Column securing section 143 is also connected to column 130. The column fixing section 143 is substantially parallel to the upper beam 111. The column fixing section 143 has a larger contact area with the column 130 to improve the connection strength and prevent the column 130 from falling off. The column fixing section 143 and the column 130 are connected in a surface contact manner. Preferably, post-securing section 143 is adhesively attached to post 130. An insulating tape 145 is provided between the column fixing section 143 and the column 130, and the insulating tape 145 is used for bonding the column fixing section 143 and the column 130. The insulating tape 145 may be previously attached to the column 130 and then contacted with the column fixing section 143. From this, stand fixed section 143 plays the constraint effect to the top of stand 130, and stand 130 is connected to stand fixed section 143 of being convenient for, and the processing of being convenient for prevents that stand 130 from rocking excessively.

The side structure 100 further includes an upper stopper 150, and the upper stopper 150 is used to limit the moving distance of the upright 130 in the horizontal direction or the acting force direction. The insulation material 115 is foam-molded, and the column 130 is located between the inner wall plate 113 and the outer wall plate 114, so that the phenomenon that the outer wall plate 114 and the inner wall plate 113 are dented or deformed due to the foaming action can be prevented. During foaming, insulation 115 expands or contracts, thereby exerting a play force on column 130, causing column 130 to rock. The top of column 130 is located in upper limit 150, upper limit 150 may limit the distance that column 130 moves in the horizontal direction, or upper limit 150 may limit the distance that column 130 moves in the direction of the applied force. The bottom of column 130 is connected to lower beam 112, and lower beam 112 provides a vertical displacement distance for column 130. In the present embodiment, the horizontal direction is parallel to the longitudinal direction and the thickness direction of the side structure 100, and the vertical direction is parallel to the height direction of the side structure 100.

The upper stopper 150 is connected to the upper beam 111, and a space closed in a horizontal direction is formed between the upper stopper 150 and the upper beam 111. The heat insulating material 115 is foam-molded in the space between the upper stopper 150 and the upper beam 111, and generates a force in the horizontal direction to the column 130. The top of column 130 is positioned in upper stop 150, and upper stop 150 limits the distance column 130 moves in the horizontal or force direction to avoid deflection due to excessive column 130 movement.

Specifically, the upper stopper 150 has a substantially U-shaped cross-sectional shape. The upper retainer 150 and the upper fixture 140 may be disposed substantially in parallel. The upper fixture 140 is located in the upper limiter 150. The upper stopper 150 includes two first stopper sections (a first left stopper section 151 and a first right stopper section 152) substantially perpendicular to the upper beam 111, and a second stopper section 153 connecting the two first stopper sections, the second stopper section 153 being substantially parallel to the upper beam 111. The U-shaped opening direction of the upper stopper 150 is substantially directed toward the upper beam 111. The opening direction of the upper stopper 150 is substantially parallel to the opening direction of the upper fixture 140.

The first left and right limiting segments 151 and 152 are connected to the upper beam 111, respectively. The first left limiting segment 151 and the first right limiting segment 152 each include a first end and a second end, and the first ends of the first left limiting segment 151 and the first ends of the first right limiting segment 152 are respectively connected with the upper beam 111, so as to reduce the contact area between the upper fixing segment and the upper beam 111, and reduce heat transfer. The first left and right spacing segments 151 and 152 are connected to the upper beam 111 in a point contact manner. The second end of the first left limiting segment 151 and the second end of the first right limiting segment 152 are connected to the second limiting segment 153, respectively, to form a whole. The upper limiting member 150 and the upper beam 111 may form a closed space along a horizontal direction, and the thermal insulation material 115 may be filled in the space between the upper limiting member 150 and the upper beam 111 to enhance thermal insulation performance, reduce heat loss, and prevent sagging or deformation due to foaming. The top of the column 130 and the upper fixture 140 are both positioned in the upper stopper 150 to limit the moving distance of the column 130 in the horizontal direction.

Further, column 130 has a generally U-shaped cross-sectional shape with a turned-out edge. The cross-sectional shape of column 130 is generally inverted omega-shaped. Column 130 includes two column stages and a column connecting section 133 connecting the two column stages, column connecting section 133 being substantially parallel to upper beam 111. The column connecting section 133 is connected to the upper beam 111. Preferably, the column connecting section 133 may be connected with the upper beam 111 by an upper fixing member 140. The column connecting section 133 is substantially parallel to the column fixing section 143, and the column connecting section 133 may be connected to the column fixing section 143 by bonding.

The opening direction of the column 130 is opposite to the opening direction of the upper stopper 150. The opening direction of the upright 130 faces away from the direction of the upper beam 111. The cross-sectional shapes of the first and second abutment stages 131, 132 are each substantially L-shaped. The first and second abutment stages 131, 132 each have a turned-out edge that is substantially parallel to the upper beam 111. The first and second spar stages 131, 132 also each have a vertical section that is substantially perpendicular to the upper beam 111. The flange is connected to the column connecting section 133 by a vertical section. The flange is closer to the second spacing section 153 than the post connecting section 133. Thereby, the column 130 and the upper fixture 140 can be stably connected.

Insulation 115 fills between column 130 and upper retainer 150 to enhance insulation and reduce heat transfer. The thermal insulation material 115 is foamed in the upper limiting member 150, and the thermal insulation material 115 expands or contracts, so as to apply a play force to the upright 130, and gaps are formed between the first upright stage 131 and the second upright stage 132 and the second limiting section 153, so that a small amount of allowance is left for the movement of the upright 130 in the horizontal direction. Of course, after the heat insulating material 115 is foamed, the column 130 may be bonded to the second limiting section 153 by the foaming material, for example, the first column stage 131 and/or the second column stage 132 may be bonded to the second limiting section 153, which is not intended to be limited in this embodiment.

Column 130 is also spaced from a first stop that can constrain the distance column 130 moves along the length of side structure 100. The first abutment stage 131 is spaced apart from the first left limiting section 151 and the second abutment stage 132 is spaced apart from the first right limiting section 152 to leave a distance of movement of the upright 130 in a horizontal direction such that the upright 130 can rock in the horizontal direction.

As shown in fig. 4, the bottom of column 130 is connected to underbeam 112 in an indirect manner. Side structure 100 also includes lower support 160, lower support 160 being used to connect column 130 with lower beam 112. The lower support 160 is located between the inner wall panel 113 and the lower beam 112. The lower support 160 is connected to the lower beam 112 along one side of the side structure 100 in the thickness direction, alternatively, the lower support 160 may be connected to the lower beam 112 by welding. The lower support 160 is spaced apart from the inner wall plate 113 along the other side of the thickness direction of the side structure 100, and the lower support 160 is not in contact with the inner wall plate 113. Heat is transferred to the lower support 160 through the lower beam 112.

Alternatively, the bottom of the outer wall panel 114 is located laterally of the lower beam 112 in the thickness direction of the side structure 100 and is connected to the lower beam 112. A portion of the outer wall panel 114 is located between the lower beam 112 and the inner wall panel 113. The bottom of the column 130 in the height direction of the side structure 100 may be connected to the lower beam 112 through a lower support 160. Heat may be transferred to the bottom of column 130 through lower support 160. Thus, the column 130 is not in direct contact with the lower beam 112, and heat is indirectly transferred to the column 130 through the lower support 160, thereby reducing the occurrence of a thermal bridge phenomenon.

Further, as shown in fig. 7, the cross-sectional shape of the lower support 160 is substantially U-shaped. Thus, the bottom of column 130 is connected to underbeam 112 by lower support 160 in point-to-surface contact. The lower support 160 includes two lower beam support sections (first lower beam support section 161 and second lower beam support section 162) substantially perpendicular to the lower beam 112, and a column support section 163 connecting the two lower beam support sections, the column support section 163 being substantially parallel to the lower beam 112. The U-shaped opening of the lower beam 112 fixture is directed generally toward the lower beam 112. The first and second lower beam support sections 161 and 162 are connected to the lower beam 112, respectively.

The first and second lower beam support sections 161 and 162 each include first and second ends, the first ends of the first and second lower beam support sections 161 and 162 being connected to the lower beam 112, respectively, to reduce the contact area of the lower support 160 with the lower beam 112 to reduce heat transfer. The first and second lower beam support sections 161 and 162 are connected to the lower beam 112 in a point contact manner. The second ends of the first and second lower beam support sections 161 and 162 are connected to the column support sections 163, respectively, to form a single body. The lower support 160 and the lower beam 112 may form a closed space in a horizontal direction, and the heat insulation material 115 may be filled in the space between the lower support 160 and the lower beam 112 to enhance heat insulation performance, reduce heat loss, and prevent sagging or deformation due to foaming.

Column support section 163 is also connected to column 130. The column support section 163 is generally parallel to the underbeam 112. The column support section 163 and the column 130 have a larger contact area therebetween to improve the connection strength and prevent the column 130 from falling off. Column support section 163 and column 130 are connected in face contact. Preferably, post support section 163 is connected to post 130 by welding. Thus, lower support 160 may provide sufficient support and restraint for column 130, column support section 163 restrains the bottom of column 130 such that column 130 does not move in the height direction of side structure 100, and in combination with upper restraint 150 may control the displacement of column 130, enabling controllability of the displacement of column 130. Preferably, the pillar connecting section 133 is connected with the pillar supporting section 163, so that the pillar 130 is connected to the pillar supporting section 163, and processing is facilitated, and the inner wall plate 113 and the outer wall plate 114 are prevented from being depressed or deformed during foaming.

In the embodiment shown in fig. 2, the side structure 100 further includes a strapping device 170, the strapping device 170 being connected to the inner wall panel 113 for strapping the load. Specifically, as shown in fig. 5, the binding device 170 includes a binding groove 171, a binding sheet 172, and a binding connector 173, and the binding groove 171 is connected to the binding sheet 172. The binding sheet 172 is used for connection with the goods, and the binding groove 171 is used for connection with the inner wall plate 113. The strapping groove 171 may clamp the inner wall plate 113. Preferably, the binding 170 may also be coupled to the post 130 to enhance the coupling strength of the binding 170 and prevent deformation of the inner wall panel 113.

The strapping groove 171 is also connected to a strapping connector 173. Strapping connector 173 is connected to column 130. Alternatively, strapping connector 173 may be connected to post 130 by welding. For example, the strapping connector 173 may be connected to a pole step. In this way, the load bearing strength of the strapping device 170 can be improved, improving quality and usability. The binding groove 171 is connected to the column 130 via a binding connector 173, and the binding sheet 172 is inserted. The positions of the binding device 170 and the upright 130 along the height direction of the side structure 100 can be adjusted according to practical situations, and the whole binding device 170 can be matched with the inner wall plate 113, the outer wall plate 114 and the heat insulation material 115 to form a high-strength bearing integral structural member, so that invisible heat bridge areas are reduced, and daily binding bearing requirements are met.

The invention also provides a container, which comprises the side structure.

The container can be a refrigerated container, can provide good quality and heat preservation performance, can effectively solve the problem of an internal and external heat bridge of the refrigerated container with the function of bundling goods, and reduces the heat leakage phenomenon of a side structure. The side structure further comprises a strapping device connected to the upright. Therefore, the bearing strength of the binding device is improved, and the product quality and the service performance of the refrigerated container are improved.
