Description

Technical Field

[0001] The utility model generally relates to the technical field of container structures, and more particularly to a folding container end wall and a folding container. Background Art

[0002] Folding boxes are special containers that can be stacked and interlocked together when empty, thus reducing the space occupied during return transport. Figures 1 to 4 The existing folding box 10 generally includes a base frame 11 and two folding box end walls 13 respectively located at the two ends of the base frame 11. A fixed hinge 18 is connected to each of the four end corners of the base frame 11. The two sides of each end wall 13 are respectively connected to a movable hinge 19. The movable hinges 19 on both sides of the end wall 13 are respectively connected to the two fixed hinges 18 at one end of the base frame 11. The movable hinges 19 and the fixed hinges 18 are pivotally connected through hinge pins 20. In this way, the end wall 13 can rotate relative to the base frame 11, and the end wall 13 can be folded and placed horizontally on the base frame 11. Among them, a floor 12 for loading goods is installed on the base frame 11. The floor 12 is a wooden floor parallel to each other with corresponding gaps or no gaps, or an iron floor.

[0003] The end wall 13 of the folding box generally includes two corner columns 14, an upper end beam 15 welded between the top ends of the two corner columns 14, a lower end beam 16 welded between the bottom ends of the two corner columns 14, and an end plate 17. The four sides of the end plate 17 are respectively welded and fixed to the two corner columns 14, the upper end beam 15, and the lower end beam 16. In order to increase the flatness and strength of the end plate 17 and meet the relevant requirements of ISO on the end wall 13, it is usually necessary to longitudinally press a plurality of convex ribs 17a that are parallel to each other and face the inside of the box on the end plate 17. When the folding box is used as a platform box or stacked, the end wall 13 is placed on the bottom frame 11 so that the end wall 13 is placed horizontally. The convex rib 17a forms a depression on the outer surface of the end plate 17. In order to avoid interference with the convex rib 17a, the floor 12 often needs to open an avoidance area 12a on the floor 12, such as a chamfer or a groove for avoidance. Due to the ISO restrictions on the strength of the floor 12, the number and position of the avoidance chamfers or grooves that can be opened are limited, which limits the number and position of the ribs 17a. At the same time, in order to ensure that the chamfers or grooves of the floor 12 and the ribs 17a match, higher assembly accuracy and requirements are required. Figure 4 1 shows some situations where the ribs 17a cooperate with the floor 12. Some boxes have to give up the ribs 17a because the floor 12 cannot be chamfered or grooved to avoid it.

[0004] Therefore, it is necessary to provide a folding box end wall and a folding box to at least partially solve the above problems. Utility Model Content

[0053] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0054] The utility model provides a folding box end wall.

[0055] See also Figure 5 The end wall 113 may include an end plate 117 having a convex rib 117 a , wherein the convex rib 117 a is configured to not protrude relative to an inner side surface of the end plate 117 and to protrude relative to an outer side surface of the end plate 117 .

[0056] According to the folding box end wall 113 of the utility model, even if the floor does not have an escape zone, the convex rib 117a can avoid interference and misalignment with the floor, and there is no need to consider the problem of the convex rib and the escape zone of the floor when assembling. Because it is not restricted by the floor, the number of convex ribs 117a can be increased, the spacing and position of the convex ribs 117a can be adjusted, and the convex ribs 117a can be pressed from different directions to make the convex ribs 117a more reasonable, so as to improve the flatness and strength of the end wall 113 and reduce the difficulty and requirements of assembly.

[0057] It should be noted that the inner side of the end plate 117 (or the end wall 113) is a plane facing the inside of the folding box, and correspondingly, the outer side of the end plate 117 (or the end wall 113) is a plane facing the outside of the folding box. Figure 5 In the figure, the plane of the end plate 117 that can be visually seen is the outer side surface of the end plate 117.

[0058] Please continue reading Figure 5 Specifically, the end wall 113 further includes a corner column 114, an upper end beam 115, and a lower end beam 116. The corner column 114 extends along the vertical direction DH, and the corner columns 114 are arranged in pairs, and adjacent corner columns 114 are spaced along the horizontal first direction D1. The upper end beam 115 extends along the first direction D1 and is vertically connected to the corner column 114. The lower end beam 116 extends along the first direction D1 and is located below the upper end beam 115, and the lower end beam 116 is vertically connected to the corner column 114. It should be noted that along the vertical direction DH, both ends of the corner column 114 protrude from the upper end beam 115 and the lower end beam 116. The end wall 113 further includes a movable hinge 119, which is connected to the corner column 114 and / or the lower end beam 116, and the movable hinge 119 protrudes downward from the corner column 114. Further, the end plate 117 includes a side edge 117b, a top edge 117c, and a bottom edge 117d. The side edge 117b is connected to the corner column 114, the top edge 117c is connected to the upper end beam 115, and the bottom edge 117d is connected to the lower end beam 116. The end wall 113 further includes a reinforcing plate 121 and an angle piece 122. The angle piece 122 is connected to the top of the corner column 114. The reinforcing plate 121 is located between the angle piece 122 and the upper end beam 115 and abuts against the corner column 114 to improve the overall structural strength of the end wall 113.

[0059] See also Figure 6 As can be understood, the end plate 117 is usually connected to the corner column 114, the upper end beam 115 and the lower end beam 116 by welding. In order to improve the welding performance of the rib 117a, thereby improving the welding performance of the end wall 113 as a whole, the two ends of the rib 117a also have inclined surfaces 117e arranged opposite to each other.

[0060] See also Figure 7 and Figure 8 , the two ends of the rib 117a extend along the vertical direction DH to the top edge 117c and the bottom edge 117d respectively, and the adjacent ribs 117a are spaced along the first direction D1. Since the arrangement of the rib 117a of the utility model is not limited by the floor, alternatively, the two ends of the rib 117a extend along the first direction D1 to the side edge 117b respectively, and the adjacent ribs 117a are spaced along the vertical direction DH. Alternatively, the rib 117a is configured to be inclined relative to the horizontal direction, and multiple ribs 117a are parallel to each other or cross each other. Please refer to Fig. 9The range of the inclination angle Z of the aforementioned inclined surface 117e relative to the end plate 117 is: 0<Z<90°, for example, 10°, 20°, 30°, 40°, 50°60°, 70°, 80°, etc.

[0061] The utility model also provides a folding box (not shown), which comprises a base frame and the aforementioned folding box end wall 113, the end wall 113 being pivotally connected to the base frame between a folded position and an opened position around a horizontal first direction D1, for example, being connected to the base frame through a movable hinge 119. Fig.10 , Fig.10 The figure shows the cooperation between the end plate 117 and the floor 112 when the end wall 113 is in the folded position. The floor 112 can be constructed as a wooden floor, an iron floor, etc. The top surface of the floor 112 is constructed as a flat surface, that is, no avoidance area is required. There can be multiple floors 112, and the multiple floors 112 are abutted or spaced in sequence in the horizontal direction, for example Fig.10 In (a), a plurality of floors 112 are spaced apart in the horizontal direction. Fig.10 In (b), the floor 112 is integrally formed, or in other words, multiple floor panels 112 are abutted against each other in the horizontal direction (without gaps). In addition, the rib 117a can be constructed to be concave toward the outer side relative to the inner side of the end plate 117. When the end wall 113 is in the folded position, the rib 117a protrudes upward from the end plate 117. For further details, please refer to Fig.10 In (a), the dimension W1 of the rib 117a protruding upward relative to the end plate 117 is in the range of 0<W1<20mm, for example, 5mm, 10mm, 15mm, etc., and the dimension W2 of the rib 117a along the first direction D1 is in the range of 0<W2<50mm, for example, 10mm, 15mm, 30mm, 40mm, 45mm, etc.

[0062] According to the folding box of the utility model, the setting of the rib 117a at the end wall 113 does not need to consider the problem of matching with the floor 112, so that the setting of the rib 117a is more reasonable, the flatness and structural strength of the end wall 113 are improved, and the assembly difficulty and requirements of the end wall 113 and the base frame are reduced.
