Therefore, it is urgent for the technical personnel in the field to solve the above-mentioned technical problems. SUMMARY

[0004] The utility model discloses in order to solve the container top plate of prior art needs integral installation, and the top plate volume is relatively large, and the installation process is complex, and the top plate is dangerous when installed, and provides a collapsible container of top.

[0005] The technical scheme adopted by the utility model has:

[0006] The application discloses a collapsible container, which comprises side plates, a bottom plate, a top plate and slide rails, the bottom plate is provided with the side plates on both sides, the side plates are provided with the slide rails on the top, the top plate is arranged between the two slide rails on the top of the side plates, and the top plate comprises a first top plate and a second top plate, the first top plate is slidably arranged between the slide rails, the bottom of the first top plate is provided with a sliding groove, and the second top plate is slidably arranged in the sliding groove.

[0007] By adopting the technical scheme, the top plate is divided into the first top plate and the second top plate, and the first top plate and the second top plate are slidably arranged along the slide rails and the sliding groove respectively, so that the installation process of the top plate is greatly simplified. Compared with the traditional hoisting mode of an integral block, the mode does not need large hoisting equipment, reduces the requirement on the environment and improves the installation efficiency. The split-type sliding installation mode reduces the installation risk caused by the weight and the volume, so that the installation process is safer. In addition, due to the reduction of the sizes of the components, the safety in the transportation process is improved, and the slidable characteristic of the top plate endows the container with greater flexibility. The position of the top plate or part of the top plate can be adjusted according to actual requirements, so as to adapt to different cargo loading requirements, such as loading and unloading of oversized articles. If the top plate needs to be checked, maintained or replaced, only the corresponding first top plate needs to be processed, and the whole container does not need to be disassembled, so that the maintenance work is greatly simplified, and time and cost are saved.

[0008] Further, the top of the top plate is provided with a positioning member, the positioning member comprises a positioning protrusion and a buckling bent plate, two groups of the top plates are arranged, the two groups of the top plates are symmetrically arranged, the second top plate on one side of the two groups of the top plates is provided with the positioning protrusion, the second top plate on the other side of the two groups of the top plates is provided with the buckling bent plate, and the positioning protrusion is welded on the second top plate below the buckling bent plate.

[0009] By adopting the technical scheme, the positioning protrusion and the buckling bent plate ensure the accurate butt joint between the two groups of the top plates. This not only makes the installation process simpler and faster, but also guarantees the close connection between the top plates, avoids the security risks caused by misalignment, and prevents the top plates from deviating or leaving the track in the sliding process, so as to enhance the structural stability and safety of the whole top plate system. Especially when bumps or impacts are encountered in the transportation process, the positioning member can play an important fixing role. Through the close cooperation of the positioning protrusion and the buckling bent plate, a good sealing effect can be formed between the top plates, external impurities such as rainwater and dust are prevented from entering the container, the goods are protected from environmental factors, and when the top plate needs to be checked or maintained, the design of the positioning member makes it more convenient to disassemble and reassemble the top plate. Maintenance personnel can quickly and accurately separate or combine the top plates without complex tools or steps.

[0010] Further, the slide rail is provided with a limiting mounting block at both ends, the limiting mounting block is provided with a through pin shaft mounting hole at both sides, and the limiting mounting block is provided with a mounting hole at the top, and the side adjacent to the pin shaft mounting hole abuts against the opening end of the slide rail, and the limiting mounting block is welded with the slide rail.

[0011] By adopting the above technical scheme, the limiting mounting block is located at both ends of the slide rail, effectively preventing the top plate from accidentally sliding out of the slide rail during sliding. This is crucial for ensuring the safety and integrity of the container, especially when encountering severe vibration or impact during transportation. By welding the limiting mounting block with the slide rail, not only the rigidity of the slide rail itself is increased, but also the structural stability of the entire top plate system is strengthened. The welding point serves as a firm connection part that can withstand a large force without being easily damaged. The limiting mounting block defines the maximum sliding range of the top plate, ensuring its movement within the predetermined area and avoiding mechanical failure caused by excessive stretching or contraction. This helps to maintain the normal operation of the top plate system and prolong its service life. The pin shaft mounting hole on the limiting mounting block allows the use of a pin shaft to quickly fix other components, such as a baffle or other additional facilities. This modular design simplifies the assembly process and also makes subsequent maintenance and repair more convenient and efficient.

[0012] Further, the side plate and the top plate are provided with a baffle at the top.

[0013] By adopting the above technical scheme, the baffle covers the junction of the side plate and the top plate, effectively preventing rain, dust and other external impurities from entering the container interior. This not only protects the goods from environmental factors, but also reduces potential damage caused by external substances. The presence of the baffle makes the container appearance more neat and unified, improving the overall visual effect. The baffle is connected to the limiting mounting block through the four top corners of the bottom and the mounting hole, forming an additional reinforcing structure. This connection method enhances the overall rigidity of the container top, especially when subjected to external pressure or impact, providing better support. The design of the connecting block and the mounting hole allows the baffle to be quickly and accurately installed in place, and can also be easily disassembled. This provides great convenience for maintenance, inspection or adjustment of the top plate system, saving time and labor costs. The baffle not only blocks external factors, but also has a certain protective effect.

[0014] Further, the connecting block and the mounting hole are fixed together through a pin shaft.

[0015] By adopting the above technical scheme, the pin shaft connection allows the shielding plate and its connecting block to be quickly and accurately combined with or separated from the mounting hole on the limiting mounting block. This greatly simplifies the assembly and disassembly process, reduces the installation time and labor cost, and also facilitates subsequent maintenance and inspection. As a mechanical fastener, the pin shaft can provide reliable fixing effect to ensure that the shielding plate will not loosen or fall off due to vibration or impact during transportation. This strong connection enhances the overall structural stability of the container, effectively preventing the shielding plate from accidentally coming off and avoiding potential safety hazards. Especially in the case of high-speed driving or encountering severe bumps, the pin shaft connection provides additional safety protection. When the roof system needs to be adjusted, repaired or replaced, the shielding plate can be easily removed by simply removing the pin shaft without the need for complex tools. This design makes maintenance work more convenient and efficient, reducing the difficulty of maintenance.

[0016] Further, the limiting mounting blocks are provided with positioning rods, one side of the positioning rod is provided with a positioning groove matched with the top plate one, the top plate one is slid into the slide rail on both sides, one end of the top plate one is clamped into the positioning groove, and the top plate one is fixed in the positioning groove through bolts.

[0017] By adopting the above technical scheme, the positioning rod and the positioning groove thereon provide a clear installation position and sliding range for the top plate one. This ensures that the top plate one can be accurately installed in place, avoiding functional failure or safety hazards caused by positional deviation. By clamping one end of the top plate one into the positioning groove and fixing it with bolts, not only the connection strength between the top plate one and the positioning rod is enhanced, but also the structural stability of the entire roof system is improved. This fixing method can effectively resist vibration and impact during transportation, ensuring the safety and reliability of the roof. The design of the positioning groove makes the installation of the top plate one more simple and efficient. Workers only need to slide the top plate one into the slide rail and align the positioning groove for insertion to complete the preliminary positioning, and then use bolts for final fixing. This method significantly improves the installation efficiency and accuracy, reduces manual operation errors, and allows the top plate one to be quickly disassembled when needed for inspection, repair or replacement. Maintenance personnel can easily loosen the bolts without complex tools to remove the top plate one for necessary operations, and then reinstall and tighten it.
