Description

Technical Field

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

[0002] In today's road freight transportation industry, the stake box, as a key cargo-carrying component, is widely used in various trucks and semi-trailers. Its unique fence-like structure design not only effectively prevents cargo from slipping off, but also greatly facilitates cargo loading and unloading operations. Furthermore, it can significantly reduce air resistance when the vehicle is empty, thereby reducing fuel consumption. Therefore, it occupies an extremely important position in the logistics transportation field.

[0003] Chinese utility model patent CN220410722U discloses a detachable cargo box. It utilizes protective components and partitions to expand the cargo box's load-bearing capacity based on the original design, and the components are assembled using bolts. This ensures rapid assembly of the cargo box structure, making assembly and disassembly more convenient and efficient, and facilitating transportation. However, the main frame of this cargo box, such as the bottom plate and side plates, is fixedly connected and cannot be disassembled. Furthermore, the protective components in this design are quite long, resulting in a large span when rotated and unfolded laterally. This not only occupies a lot of space but also poses safety hazards and is inconvenient to operate.

[0004] Therefore, there is an urgent need to improve the existing stake box and provide a detachable stake box that is quick and easy to assemble and disassemble. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a detachable cargo box that is reasonably designed, simple in structure, quick and easy to assemble and disassemble, easy to operate, and convenient to open and close, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable cargo box, comprising:

[0008] The main frame includes a base plate, a top frame, and several support frames evenly distributed between the two. The base plate and the top frame are each fixed with a connecting piece on the side that is close to each other, and the connecting piece corresponds one-to-one with the support frame.

[0009] Side baffles are connected to the base plate via hinges. Multiple side baffles are located between two adjacent support frames. An interception component is also provided directly above each side baffle.

[0010] Each of the support frames has a sliding groove inside both ends, and a locking mechanism is provided in the sliding groove to lock the support frame and the docking part.

[0011] Preferably, the bottom end face of the base plate is fixedly provided with several bases for docking and installation with the truck, and a sealing plate is fixedly installed between the right sides of the base plate and the top frame by bolts.

[0012] Preferably, the top surface of the top frame is provided with several tarpaulin supports at equal intervals along its length, and the front and rear ends of the tarpaulin supports are provided with arc-shaped sections to avoid puncturing the tarpaulin.

[0013] Preferably, the interception assembly includes a fixed rod, a movable rod, vertical rods, and a telescopic linkage mechanism. The fixed rod is fixedly installed on the corresponding support frame by bolts. A movable rod is provided on one side of the fixed rod. Several vertical rods are provided between the fixed rod and the movable rod. The fixed rod, the movable rod, and the several vertical rods are all on the same vertical plane and are all hinged to the telescopic linkage mechanism.

[0014] Preferably, the fixed rod, movable rod, and several vertical rods are always equidistantly distributed, and the telescopic linkage mechanism is provided in two sets and is arranged symmetrically about the fixed rod.

[0015] Preferably, a tensioning mechanism is installed on the outer wall of both the movable rod and the side baffle. The surfaces of the top frame and the support frame are fixed with positioning hooks corresponding to the tensioning mechanism. The tensioning mechanism cooperates with the positioning hooks to achieve the positioning of the movable rod and the side baffle.

[0016] Preferably, the locking mechanism includes a positioning block that engages and slides within the groove, a spring that is fixedly connected between the positioning block and the inner wall of the groove, and a nut that is embedded and fixed through the middle inner wall of the groove, with a long bolt connected to the internal thread of the nut.

[0017] Preferably, the connection between the docking component and the support frame is a plug-in connection, and the docking component and the positioning block are provided with a serrated structure that can interlock on the side that is close to each other.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, both the base plate and the top frame are connected to the support frame via a docking part and a locking mechanism. When the docking part is inserted into the support frame, the serrated structure on the side of the docking part and the positioning block that are close to each other can engage to achieve initial positioning. Then, the long bolt is tightened with a tool so that one end of it abuts against the positioning block, thereby positioning the positioning block and making it stably engaged with the docking part, thus completing the stable assembly of the main frame. Similarly, the base plate, several support frames, the top frame and the sealing plate in this device can all be disassembled individually, allowing for more thorough disassembly and convenient timely replacement of each component.

[0020] In this device, after the tensioning mechanism is separated from the positioning hook, two sets of telescopic linkage mechanisms can be used to control the movable rod and several vertical rods to slide synchronously and retract towards the fixed rod. Then, the tensioning mechanism can be connected with another positioning hook to position the interception component in the retracted state. Unlike the rotation opening method in the comparative document, this device uses a telescopic method to open and close, which is not only more convenient to operate, but also does not occupy a lot of road space and avoids potential safety hazards. The tensioning mechanism is a mature existing mechanism that has been widely used in cargo boxes. Its specific structure and principle are existing technologies, so they will not be described in detail. Attached Figure Description

[0031] like Figure 1-6 As shown in one example, the detachable cargo box of this utility model includes:

[0032] The main frame includes a base plate 1, a top frame 3, and several support frames 5 evenly distributed between the two. The base plate 1 and the top frame 3 are fixed with connecting parts 4 on the side that are close to each other. The connecting parts 4 correspond one-to-one with the support frames 5.

[0033] Side baffles 6 are connected to the base plate 1 by hinges. Multiple side baffles 6 are located between two adjacent support frames 5. An interception component 7 is also provided directly above each side baffle 6.

[0034] The slide groove 12 is provided inside both ends of each support frame 5. The slide groove 12 is provided with a locking mechanism for locking the support frame 5 and the docking part 4.

[0035] As a preferred embodiment, based on the above structure, preferably, a plurality of bases 2 are fixedly provided on the bottom end face of the base plate 1 for docking and installation with the truck, and a sealing plate 11 is fixedly installed between the right sides of the base plate 1 and the top frame 3 by bolts.

[0036] In this embodiment, several bases 2 are fixedly installed on the bottom end face of the base plate 1 to facilitate the installation of the cargo box between the cargo box and the truck.

[0037] As a preferred embodiment, based on the above structure, preferably, a plurality of rain cover brackets 10 are fixedly provided at equal intervals along the length direction on the top surface of the top frame 3, and the front and rear ends of the rain cover brackets 10 are provided with arc-shaped sections to avoid puncturing the rain cover.

[0038] In this embodiment, the arrangement of several tarpaulin brackets 10 facilitates the support of the tarpaulin, making the installation and use of the tarpaulin convenient.

[0039] In a preferred embodiment, based on the above structure, the interception component 7 preferably includes a fixed rod 71, a movable rod 72, a vertical rod 73, and a telescopic linkage mechanism 74. The fixed rod 71 is fixedly installed on the corresponding support frame 5 by bolts. A movable rod 72 is provided on one side of the fixed rod 71. A plurality of vertical rods 73 are provided between the fixed rod 71 and the movable rod 72. The fixed rod 71, the movable rod 72, and the plurality of vertical rods 73 are all on the same vertical plane and are all hinged to the telescopic linkage mechanism 74.

[0040] As a preferred embodiment, based on the above structure, preferably, the fixed rod 71, the movable rod 72 and several vertical rods 73 are always equidistantly distributed, and the telescopic linkage mechanism 74 is provided in two sets and is arranged symmetrically about the fixed rod 71.

[0041] In this embodiment, the telescopic linkage mechanism 74 is provided, which can be used to open and close the device by telescopic means. This not only makes the operation more convenient, but also avoids occupying a lot of road space and prevents potential safety hazards.

[0042] As a preferred embodiment, based on the above structure, preferably, a tensioning mechanism 8 is installed on the outer wall of both the movable rod 72 and the side baffle 6, and a positioning hook 9 is fixedly provided on the surface of both the top frame 3 and the support frame 5 corresponding to the tensioning mechanism 8. The tensioning mechanism 8 cooperates with the positioning hook 9 to achieve the positioning of the movable rod 72 and the side baffle 6.

[0043] In this embodiment, the positioning of the side baffle 6 and the interception component 7 can be achieved by connecting the tensioning mechanism 8 with the positioning hook 9. The tensioning mechanism 8 is a mature existing mechanism that is widely used in cargo boxes. Its structure and principle are existing technologies, so they will not be described in detail.

[0044] As a preferred embodiment, based on the above structure, the locking mechanism preferably includes a positioning block 14 that engages and slides within the slide groove 12, a spring 13 that is fixedly connected between the positioning block 14 and the inner wall of the slide groove 12, and a nut 15 that is embedded and fixed through the inner wall of the middle part of the slide groove 12, with a long bolt 16 connected to the internal thread of the nut 15.

[0045] As a preferred embodiment, based on the above structure, it is preferable that the connection between the docking member 4 and the support frame 5 is a plug-in connection, and the docking member 4 and the positioning block 14 are provided with a serrated structure that can interlock on the side that is close to each other.

[0046] In this embodiment, the serrated structures on the adjacent sides of the docking piece 4 and the positioning block 14 can interlock to achieve initial positioning. Then, the long rod bolt 16 is tightened with a tool so that one end of it abuts against the positioning block 14, thereby positioning the positioning block 14 and making it stably interlocked with the docking piece 4, completing the stable assembly of the main frame. Similarly, it facilitates the timely replacement of each component.

[0047] The working principle of this utility model is as follows:

[0048] In use, the base plate 1 is first fixedly installed on the truck by several bases 2 fixed on its bottom end face. Then, the support frame 5 and the top frame 3 are installed on the top plate 1 in sequence. When the docking parts 4 fixed on the side of the base plate 1 and the top frame 3 are close to each other, they are inserted into the corresponding support frame 5. The serrated structure on the side of the docking parts 4 and the positioning block 14 close to each other can be engaged to achieve initial positioning. Then, the long rod bolt 16 can be tightened with existing tools to move under the action of the nut 15 and abut against the positioning block 14 for positioning. This facilitates the stable engagement between the positioning block 14 and the docking parts 4 and completes the stable assembly of the main frame. Similarly, the base plate 1, several support frames 5, top frame 3 and sealing plate 11 in this device can be disassembled individually, making disassembly more thorough and facilitating timely replacement of each component.

[0049] After separating the tensioning mechanism 8 from the positioning hook 9, the movable rod 72 and several vertical rods 73 can be controlled by two sets of telescopic linkage mechanisms 74 to slide synchronously and retract towards the fixed rod 71, thereby retracting the interception component 7. Subsequently, the tensioning mechanism 8 can be connected to another positioning hook 9 to position the retracted interception component 7. Unlike the rotation opening method in the comparative document, this device uses a telescopic method to achieve opening and closing, which is not only more convenient to operate, but also does not occupy a lot of road space and avoids potential safety hazards. The tensioning mechanism 8 is a mature existing mechanism that has been widely used in truck cargo boxes. Its specific structure and principle are existing technologies, so they will not be described in detail.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
