[0045] like Figures 1 to 8 As shown, this embodiment provides a cargo compartment for a hook-arm vehicle, which includes a bottom plate 1, a fixed vertical plate 2 and a side block assembly 4. The bottom surface of the bottom plate 1 is provided with a plurality of rollers 5 to facilitate the movement of the cargo compartment. For example, the bottom surface of the bottom plate 1 is provided with four, five or six rollers 5, etc., which are specifically provided according to actual needs; the fixed vertical plate 2 is vertically arranged on one side of the bottom plate 1, and a hook plate 3 is arranged on one side of the fixed vertical plate 2, and the hook plate 3 is used to be detachably hooked with the driving hook arm of the hook-arm vehicle; the side block assembly 4 includes at least two layers of side blocks, one layer of side blocks is detachably connected to the bottom plate 1, and can be fixed to the vertical plate 2 to form a lower layer of enclosures surrounded on the bottom plate 1, and multiple layers of side blocks are detachably spliced ​​in sequence along the height direction, and each layer of side blocks is surrounded with the fixed vertical plate 2 to form an upper layer of enclosures. In this embodiment, the hook-arm vehicle includes a chassis and a driving hook arm arranged on the chassis, and the driving hook arm is connected to the hook plate 3 to tow the cargo compartment onto the chassis. The fixed vertical plate 2 arranged on the bottom plate 1 provides a support and installation surface for the hook plate 3, so that the driving hook arm of the hook arm vehicle can hook the hook plate 3 and load the cargo compartment onto the hook arm vehicle; by setting at least two layers of side guards and by the detachable setting of the side guards, it is convenient for the operator to not assemble the side guard assembly 4 according to the actual work needs, assemble a layer of lower enclosure or multiple layers of upper enclosures to meet the loading requirements of different capacities, without the need to prepare multiple types of cargo compartments, and also to save power when loading the cargo compartment, thereby saving costs and extending the service life of the driving hook arm of the hook arm vehicle. The cargo compartment of the hook arm vehicle has better flexibility in use, lower cost, wider application range, and good practicality.

[0046] Exemplarily, as Figure 1 and Figure 2 shown, the hook plate 3 includes two support rods and a cross bar connected between the two support rods. A connecting shaft 6 is rotatably connected to the cross bar. The hook of the driving hook arm can hook the connecting shaft 6. By driving the telescopic and rotational movements of the hook arm, the connecting shaft 6 is driven to move, thereby driving the cargo compartment to move, realizing the loading and unloading of the cargo compartment. Of course, in other embodiments, the hook plate 3 can also be of other structures. For example, the hook plate 3 is a triangular plate or the like, which is specifically set according to actual requirements.

[0047] Preferably, a limiting beam is provided on the bottom surface of the bottom plate 1. The limiting beam is used for limiting and clamping with a limiting member on the hook arm vehicle. The length direction of the limiting beam is the first direction, and the first direction is perpendicular to the moving direction of the driving hook arm driving the cargo compartment. When the driving hook arm drives the cargo compartment to move along the first direction, the cargo compartment is towed onto the chassis and continues to move along the first direction until the limiting beam is inserted into the limiting member provided on the hook arm vehicle. For example, the limiting member is a limiting hook or a limiting baffle, etc., to prevent the cargo compartment from continuing to move along the first direction, making the loading position of the cargo compartment accurate and having better position stability, thereby ensuring the reliability of the loading and transportation of goods or garbage.

[0048] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figures 5 to 7 shown, among the multiple layers of side guards included in the side guard assembly 4, the side guard at the lowermost layer is the first-layer side guard 41. The first-layer side guard 41 includes a plurality of first columns 411 and a plurality of first side plates 412. The plurality of first columns 411 are detachably connected to the bottom plate 1 at non-linear intervals. A first side plate 412 is provided between the first column 411 and the fixed vertical plate 2 and between every two adjacent first columns 411. One side of the first side plate 412 is detachably rotatably connected to the bottom plate 1, so that the first side plate 412 can rotate between an open position and a closed position. When the first side plate 412 is in the closed position, it can be limitedly connected to the column and / or the fixing plate. When the side guard assembly 4 does not need to be provided, the first column 411 and the first side plate 412 are removed to reduce the weight of the cargo compartment, facilitating the loading of the cargo compartment onto the chassis. The bottom plate 1 of the cargo compartment can be used to transport goods. When it is necessary to enclose and protect the goods, the first column 411 and the first side plate 412 are installed to form a lower enclosure. The accommodation space formed by the lower enclosure and the bottom plate 1 can prevent the goods from falling. At the same time, the first side plate 412 is rotatably arranged, which is convenient for loading and unloading. When the first side plate 412 is rotated to the open position, the lower enclosure changes from a closed state to a non-closed state, and it is convenient to load or unload goods from the side, improving work efficiency. After the loading and unloading are completed, the first side plate 412 is rotated to the closed position and then limitedly connected to the column and / or the fixing plate, and the position of the first side plate 412 can be fixed, which is convenient and fast, and has better use flexibility.

[0049] More specifically, as Figure 5 shown, a plurality of first insertion holes 10 are spaced on the bottom plate 1. One end of each first upright post 411 is provided with a first insertion joint, and the first insertion joint is detachably inserted into the first insertion hole 10. Through the cooperation of the first insertion joint and the first insertion hole 10, the first upright post 411 can be quickly assembled or disassembled, saving assembly time and improving work efficiency. Among them, the first insertion hole 10 is rectangular, triangular or irregular, etc., and the cross-section of the first insertion joint is rectangular, triangular or irregular, etc., and is adapted to the first insertion hole 10.

[0050] Preferably, the first upright post 411 at the corner of the bottom plate 1 is L-shaped or L-like, which is adapted to the corner to improve the structural stability of the lower enclosure.

[0051] Exemplarily, the bottom plate 1 is a rectangular plate, the fixed vertical plate 2 is vertically erected on one side of the bottom plate 1, and a first upright post 411 is detachably provided on each of the other three sides of the bottom plate 1, and a first upright post 411 is also provided at each corner of the other three sides of the bottom plate 1. Then, two first side plates 412 respectively correspond to each of the other three sides of the bottom plate 1. Under the above structure, the structural strength of the lower enclosure corresponding to each side of the bottom plate 1 is relatively high, the load-bearing capacity of the first side plate 412 is better, and it is not easy to deform. At the same time, it is convenient to open one or more first side plates 412 according to needs to meet different loading and unloading requirements. Of course, in other embodiments, the bottom plate 1 can also be in other shapes, such as triangular, pentagonal, polygonal or irregular, etc., and the number and distribution of the first upright posts 411 and the first side plates 412 are set according to the shape of the bottom plate 1, so that the cross-section of the lower enclosure matches the shape of the bottom plate 1.

[0052] In this embodiment, as Figure 1 and Figure 6 shown, a first pin seat 415 is provided on the first side plate 412, and a second pin seat 416 is provided on the side edge of the bottom plate 1. The first side plate 412 and the bottom plate 1 are rotationally connected by inserting a first U-shaped pin 417 into the first pin seat 415 and the second pin seat 416. Specifically, the first pin seat 415 has a first pin hole extending along the length direction of the first side plate 412, and the second pin seat 416 has a second pin hole extending along the length direction of the bottom plate 1. The two side arms of the first U-shaped pin 417 can be respectively inserted into the first pin hole and the second pin hole, which is not only convenient for disassembly and assembly, but also enables the first side plate 412 to rotate smoothly. Of course, in other embodiments, the first side plate 412 can also be rotationally connected to the bottom plate 1 through structures such as hinges, and the hinge and the bottom plate 1 are detachably connected by bolts, for example.

[0053] After the first side plate 412 rotates to the closed position, it is limitedly connected to the fixed vertical plate 2 or the first upright post 411 to fix the position of the first side plate 412. Specifically, asFigure 1 and Figure 7 As shown, the first layer side baffle 41 also includes a plurality of first limiting members 413 and a plurality of second limiting members 414. At least one first limiting member 413 is arranged on the side of the fixed vertical plate 2 and each first column 411, and at least one second limiting member 414 is arranged on each first side plate 412. When the first side plate 412 is in the closed position, the plurality of first limiting members 413 and the plurality of second limiting members 414 are detachably connected one by one. Exemplarily, the first limiting member 413 is a locking rod rotatably set on the fixed column or the first column 411, and the second limiting member 414 is a locking member set on the first side panel 412, and a locking groove is formed on the locking member. By rotating the locking rod, the locking rod can overlap in the locking groove, thereby achieving the limitation of the first side panel 412; or the first limiting member 413 is a locking rod movably set on the fixed column or the first column 411, and the second limiting member 414 is a locking member set on the first side panel 412, and a locking hole is formed on the locking member. By pulling the locking rod, the locking rod can be inserted into the locking hole or pulled out from the locking hole, thereby achieving the limitation and unlocking of the first side panel 412.

[0054] Preferably, if Figure 4 As shown, the two opposite sides of the first column 411 extend outward to form a first limiting plate 4111, and the first side plate 412 abuts against the first limiting plate 4111 when it is in the closed position. The first limiting plate 4111 provides a limiting and supporting function for the first side plate 412, preventing the first side plate 412 from tipping into the accommodating space, and also enables the first side plate 412 to be aligned with the side of the first column 411, thereby improving the structural strength while ensuring the aesthetic appearance. In this embodiment, the two opposite sides of the fixed vertical plate 2 form limiting steps 21, and when the first side plate 412 adjacent to the fixed vertical plate 2 is in the closed position, one side of the first side plate 412 abuts against the limiting step 21, and the other side abuts against the first limiting plate 4111 on the first column 411.

[0055] Furthermore, when the cargo compartment needs to accommodate more cargo, one or more upper enclosures can be spliced ​​above the lower enclosure. For example, among the multiple side enclosures included in the side enclosure assembly 4, the side enclosure located at the second layer from bottom to top is the second layer side enclosure 42. The second layer side enclosure 42 includes a plurality of second columns 421 and a plurality of second side panels 422. One end of each second column 421 is detachably connected to a first layer enclosure. A second side panel 422 is detachably provided between the second column 421 and the fixed vertical panel 2 and between each two adjacent second columns 421. The lower end of the second side panel 422 abuts against the end of the lower enclosure away from the bottom plate 1. By adding a second layer of enclosure to the lower enclosure, a larger accommodation space is formed between the bottom plate 1, the fixed vertical panel 2 and the two layers of spliced ​​side enclosures. The higher stacked cargo can be surrounded and protected by the second layer of side panels 42.

[0056] Optionally, the second side plate 422 is a mesh plate or a solid plate, which is configured according to actual needs.

[0057] In this embodiment, a second plug hole or a second plug connector is provided at one end of the second column 421, and a second plug connector or a second plug hole is provided at the end of the first column 411 away from the base plate 1. Through the plug-in cooperation of the second plug hole and the second plug connector, the second layer side guard 42 can be quickly disassembled and assembled, thereby improving work efficiency.

[0058] Specifically, Figure 1 and Figure 8 As shown, the second layer side guard 42 also includes a plurality of first connecting members 423 and a plurality of second connecting members 424. The first connecting members 423 are respectively provided on the opposite sides of each second side panel 422, and the second connecting members 424 are respectively provided on the side of the fixed vertical panel 2 and the second column 421. The first connecting member 423 and the second connecting member 424 are detachably connected. The second side panel 422 is fixed by connecting the first connecting member 423 and the second connecting member 424. Exemplarily, the first connecting member 423 is a third latch seat provided on the second side panel 422, and the second connecting member 424 is a fourth latch seat provided on the second column 421 or the fixed vertical panel 2. The second side panel 422 is fixed by plugging the third latch seat and the fourth latch seat through the second U-shaped latch. It is convenient and quick to disassemble and assemble the second side panel 422, thereby improving work efficiency.

[0059] Preferably, if Figure 4 As shown, the two opposite sides of each second column 421 extend outward to form a second limiting plate 4211, and the second side plate 422 abuts against the second limiting plate 4211. The second limiting plate 4211 provides a limiting and supporting function for the second side plate 422, preventing the second side plate 422 from tipping into the accommodation space, and also enables the second side plate 422 to be aligned with the side of the second column 421, thereby improving the structural strength while ensuring the aesthetic appearance. In this embodiment, one side of the second side plate 422 adjacent to the fixed vertical plate 2 abuts against the limiting step 21 on the fixed vertical plate 2, and the other side abuts against the second limiting plate 4211 on the second column 421.

[0060] This embodiment also provides a hook-arm truck, which includes the above-mentioned hook-arm truck cargo box. In this embodiment, the hook-arm truck includes a chassis and a driving hook arm arranged on the chassis, and the cargo box is towed onto the chassis by connecting the hook plate 3 through the driving hook arm. The hook-arm truck has good flexibility in use, and the number of side guard layers can be adjusted according to demand to meet different loading needs. There is no need to prepare multiple types of cargo boxes, which saves costs and occupies space. When loading the cargo box, the side guard can be removed, which is conducive to saving power, thereby helping to extend the service life of the driving hook arm.
