Description

Technical Field

[0001] This utility model belongs to the field of storage and transportation cargo box technology, and in particular relates to a cargo box top plate. Background Technology

[0002] like Figure 1 As shown, the top plate of the storage and transportation container is usually made into a corrugated plate 1 structure to increase its rigidity. The top plate needs to be welded to the top frame to connect the side plates of the container. When this corrugated plate 1 is welded to the top frame, the presence of corrugations results in a large welding length, which increases the amount of welding work. In addition, the long weld seam is prone to missed welds or broken welds, which can lead to water leakage and damage to the goods inside the container.

[0003] Therefore, in the field of storage and transportation container technology, there is still a need for research and improvement on the top plate of the container. This is a current research hotspot and focus in the field of storage and transportation container technology, and it is also the starting point for the completion of this utility model.

[0004] Therefore, the technical problem to be solved by this utility model is to provide a cargo box top plate to solve the technical problems of high welding difficulty and easy weld omission when welding corrugated plates to the top frame.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cargo box top plate, including a top plate body, wherein a plurality of roll-formed protrusions are provided at intervals on the top plate body, and both ends of the protrusions are provided with sealing slopes extending from the top surface of the protrusions to the plane of the top plate body, and the tail ends of all the sealing slopes are located on the same plane to form a welding edge.

[0006] As an improvement, the sealing slope is integrally formed with the protruding ridge.

[0007] As a further improvement, the sealing bevel is a roll-formed extension surface.

[0008] As a further improvement, the convex ridge is provided with concave and convex ribs.

[0009] As a further improvement, the concave and convex ribs are integrally formed with the convex edges.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are:

[0011] The convex rib top face extends to the top plate body plane, the end face of the convex rib is blocked by the blocking inclined surface, rainwater and the like is prevented from entering the container through the convex rib end face, the tail ends of all the blocking inclined surfaces are located on the same plane to form a welding edge, the welding edge is a straight edge, the top plate body and the top frame are conveniently welded, a straight weld is formed, the welding operation is facilitated, the weld length is reduced, and the phenomenon of incomplete welding or broken welding caused by uneven weld is avoided.

[0012] The concave-convex rib is integrally formed with the convex rib by rolling and pressing, the process steps are reduced, and the rigidity of the top plate body is improved. BRIEF DESCRIPTION OF DRAWINGS

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The terms used in this specification, such as "front," "back," "left," "right," "inner," "outer," and "middle," are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0022] like Figure 2 As shown, this utility model embodiment provides a cargo box top plate, including a top plate body 2. The top plate body 2 has a plurality of roll-formed protruding ribs 3 spaced apart. Those skilled in the art can determine the number of protruding ribs 3 based on the size of the top plate body 2, the width of the protruding ribs 3, and the spacing between the protruding ribs 3. Both ends of each protruding rib 3 have a sealing slope 4 extending from the top surface of the protruding rib 3 to the plane of the top plate body 2. The sealing slope 4 seals the end face of the protruding rib 3, preventing rainwater and other substances from entering the cargo box through the end face of the protruding rib 3. Figure 3 and Figure 4 As shown, the tail ends of all the sealing slopes 4 are located on the same plane to form welding edges 5. The welding edges 5 are straight edges, which facilitates the welding of the top plate body 2 to the top frame, forming straight welds. This not only facilitates the welding operation but also reduces the weld length and avoids the phenomenon of missed welds or broken welds caused by uneven welds.

[0023] The sealing slope 4 and the protruding ridge 3 are integrally set. The sealing slope 4 is an extension surface formed by roll forming. After roll forming, the tail end of the sealing slope 4 forms a straight welding edge 5. This not only simplifies the process but also produces a good forming effect.

[0024] The protruding rib 3 is provided with concave and convex ribs 6. The protruding direction of the concave and convex ribs 6 is opposite to that of the protruding direction of the protruding rib 3. The number of concave and convex ribs 6 is set according to the width of the protruding rib 3, usually one or two. The concave and convex ribs 6 are integrally set with the protruding rib 3. The concave and convex ribs 6 and the protruding rib 3 are integrally rolled and formed, which reduces the process steps and improves the rigidity of the top plate body 2.

[0025] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
