Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a folding container. Background Technology

[0002] A collapsible container is a type of rack-mounted container, comprising a cargo-carrying base frame and collapsible endwalls at both ends of the base frame. When empty, the endwalls can be folded onto the base frame, and the folded containers can then be linked together, reducing their space occupation. When folding the endwalls from a vertical position onto the base frame or from a folded position to a vertical position, leaf springs or tension springs are typically used to reduce the labor intensity of lifting the endwalls and to minimize the impact of them collapsing. Since lifting and lowering the endwalls relies on manual labor, and the endwalls can collapse quickly, there is a risk of the endwalls falling and injuring people, posing a safety hazard. Therefore, it is necessary to develop a collapsible container with a high safety factor. A search revealed no identical technical solutions to this invention. Utility Model Content

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0024] like Figure 1 As shown, this utility model embodiment includes: a folding container, the folding container including a cargo-carrying frame and foldable end walls disposed at both ends of the frame, the foldable end walls including base assemblies, the base assemblies being fixed to the ends of the frame; the base assemblies including a first base 110 and a second base 120 symmetrically disposed on both sides of the ends of the frame, as shown. Figure 2As shown, the first base 110 includes a first base 111 and a first side plate A112 and a first side plate B113 disposed on the top two sides of the first base 111. The first side plate A112 and the first side plate B113 are perpendicular to the top surface of the first base 111 and are arranged parallel to each other.

[0025] like Figure 3 As shown, the second base 120 includes a second base 211 and a second side plate A212 and a second side plate B213 disposed on both sides of the top of the second base 211. The second side plate A212 and the second side plate B213 are perpendicular to the top surface of the second base 211 and are arranged parallel to each other.

[0026] like Figure 4 and Figure 5As shown, the wall assembly 300 is assembled onto the base assembly via connecting components. The wall assembly 300 includes a top beam 301 and a first side beam 302 and a second side beam 303 disposed on both sides of the top beam 301. The bottom of the first side beam 302 is fixedly mounted on the top of the first connecting plate 115, and the bottom of the second side beam 303 is fixedly mounted on the top of the second connecting plate 215. A positioning plate is provided on the top of the first base 110, and a positioning groove is formed on the top plate. When the wall assembly 300 is erected, it is used to insert the first side beam 302 and the second side beam 303. At this time, the first... Side beams 302 and 303 will not excessively rotate outward due to the presence of positioning plates, thus preventing damage to the wall assembly 300. The connecting assembly includes a first connecting shaft 114 and a first connecting plate 115. The two ends of the first connecting shaft 114 are respectively fixed to the inner walls of the first side plate A112 and the first side plate B113. The bottom of the first connecting plate 115 is fixed to the first connecting shaft 114. The first connecting plate 115 can rotate between the first side plate A112 and the first side plate B113 with the first connecting shaft 114 as the axis. The two ends of the second connecting shaft 214 are respectively fixed to... On the inner sidewalls of the second side plate A212 and the second side plate B213, the bottom of the second connecting plate 215 is fixed to the second connecting shaft 214. The second connecting plate 215 can rotate between the second side plate A212 and the second side plate B213 with the second connecting shaft 214 as the axis. The folding assembly 400 is assembled on the base assembly and docks with the connecting assembly. The folding assembly 400 includes a worm gear 403 transmission device. The worm gear 403 transmission device includes a housing 401 and a worm wheel 402 and a worm 403 disposed in the housing 401. The rotation of the worm 403 can drive the worm wheel. When 402 rotates, the input shaft of the worm gear 403 extends out of the housing 401. The first and second output ports of the worm gear 402 are exposed on both sides of the housing 401. The extension direction of the input shaft is perpendicular to the extension direction of the first and second output ports. The worm gear 403 transmission device also includes a first connecting rod 404 and a second connecting rod 405. One end of the first connecting rod 404 is connected to the first output port, and the other end is connected to the end face of the first connecting shaft 114. One end of the second connecting rod 405 is connected to the second output port, and the other end is connected to the end face of the second connecting shaft 214.

[0027] The worm gear 403 transmission also includes a rotary handle, such as Figure 7 and Figure 8As shown, the rotary handle includes a rotary sleeve 601 and a handle 602 disposed on the outer wall of the rotary sleeve 601. The rotary sleeve 601 has a partition inside, and there are limiting posts 603 on both sides of the partition. The extension direction of the limiting posts 603 is consistent with the extension direction of the rotary sleeve 601. The output shaft is provided with a limiting groove 605 for the limiting posts 603 to be inserted. In use, the rotary sleeve 601 is sleeved on the input shaft. At this time, the limiting posts 603 inside are inserted into the limiting groove 605, which can effectively prevent slippage between them. Then, the handle 602 is manually rotated, and the worm gear 403 rotates, which drives the worm wheel 402 to rotate. Since the first connecting rod 404 and the second connecting rod 405 are fixedly assembled with the worm wheel 402, the first connecting rod 404 and the second connecting rod 405 will rotate synchronously and at the same frequency, so the lowering and raising of the wall assembly 300 can be freely controlled.

[0028] like Figure 6 As shown, the ratchet assembly includes a ratchet sleeve 501 and a pawl 502. The ratchet sleeve 501 has a through groove 503 for mounting the pawl 502. The pawl 502 is mounted in the through groove 503 by a pin 505. The pawl 502 has a lever 504. The housing 401 has an assembly groove for mounting the ratchet assembly located at the edge of the input shaft. The outer wall of the rotating sleeve 601 also has a rack 604 for engaging and locking with the pawl 502. The rack 604 is distributed along the circumference of the rotating sleeve 601. When the handle 602 is rotated, the ratchet assembly is mounted in the assembly groove. The lever 504 is moved to separate the pawl 502 and the rack 604. At this time, the input shaft can be rotated arbitrarily. When the wall assembly 300 is rotated into position, the lever 504 is moved again to engage with the rack 604, thereby preventing the input shaft from rotating and causing a safety hazard.

[0029] This technical solution uses a connecting rod instead of independent rotating shafts on both sides of the folding end face of the folding box, so that the folding end face can always remain on the same plane during movement. A worm gear 403 transmission device is installed in the middle of the connecting rod, and the worm wheel 402 is connected to the connecting rod by a keyway. The outer end of the worm gear 403 is connected to a ratchet sleeve 501 and a rotating handle. When the rotating handle is rotated, the worm gear 403 drives the worm wheel 402 to rotate, which achieves the folding effect. The worm gear transmission has a self-locking function, and the handle and the external ratchet sleeve 501 can further play a locking and limiting role. The ratchet sleeve 501 and the handle can be disassembled and installed in both directions to ensure that the folding end face can move in the desired direction.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
