[0001] This utility model relates to the field of logistics box technology, and in particular to a logistics box with adjustable storage space. Background Technology

[0002] Logistics boxes, also known as turnover boxes, are widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. They are resistant to acids and alkalis, oil stains, and are non-toxic and odorless. They can be used to hold food, are easy to clean, facilitate the turnover of parts, are neatly stacked, and are easy to manage.

[0003] To address the issue of inconveniently adjustable storage space in current logistics boxes, patent CN202222146691.9 discloses an adjustable storage space logistics box. This box includes an outer shell, an inner shell fixedly connected to its inner surface, and an extension shell slidably connected to the outer surface of the inner shell. A cover plate is provided on one side of the extension shell, a handle is fixedly connected to one side of the cover plate, and two hinges are fixedly connected to one side of the cover plate. One side of each hinge is fixedly connected to one side of the extension shell. Two guide rails are fixedly connected to both sides of the outer shell, and an extension shaft is fixedly connected to both sides of the extension shell. The advantages of this invention are: by using an extension shell slidably connected to the outer and inner shells, it achieves a telescopic function; by using positioning holes on the guide rails, it achieves a positioning function; and by using a positioning spring to press against a sliding block, the extension shaft can extend and retract. During use, simply pressing a button allows the entire logistics box to extend or retract, making it quite convenient.

[0004] The existing solution requires operators to use both hands to operate the adjustment mechanisms on both sides of the inner shell to adjust its height and storage space, which is inconvenient. Furthermore, currently used logistics boxes often suffer from moisture damage during transport due to the lack of internal moisture-proofing and drying features. Therefore, a logistics box with moisture-proof capabilities and easy adjustment is needed. Utility Model Content

[0005] In view of the above-mentioned technical problems, this utility model provides a logistics box with adjustable storage space. During the adjustment process, the user only needs to turn the handle to adjust the storage space of the logistics box, which improves the convenience of operation. In addition, a moisture-proof drying component is added to reduce the problem of the quality of the items in the box being affected by moisture during transportation.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An adjustable storage space logistics box includes a main body, an extension body, and a lid. The extension body is located within a telescopic groove on the main body. The lid is hinged to the top opening of the extension body. The main body features an adjustment mechanism mounted on its rear side, which is connected to a connecting block fixedly mounted on the extension body. The lid has a moisture-proof drying component.

[0008] The adjustment mechanism consists of a mounting base, a screw, a handle, a transmission assembly, a moving block, a support rod, and a locking assembly. The mounting base is fixedly mounted on the outer wall of the main housing. The screw is mounted in a moving groove on the mounting base via a bearing. The lower end of the screw is connected to the handle via the transmission assembly, which is connected to the locking assembly. The moving block is threaded onto the screw, and the moving block is fixedly connected to the support rod with screws.

[0009] The upper end of the support rod is connected to the connecting block on the expansion box.

[0010] The transmission assembly consists of a first helical tooth and a second helical tooth. The handle is fixedly disposed at one end of the central shaft of the first helical tooth.

[0011] The locking assembly comprises an adjusting screw, a fixing block, a limiting plate, a limiting block, and a retaining ring. A retaining ring is provided on the central shaft of the first helical tooth, and a ring of retaining grooves is arranged on the retaining ring. The limiting block is adapted to the retaining grooves and is fixed on the limiting plate. One end of the adjusting screw is connected to the limiting plate through a bearing, and the other end of the adjusting screw is threaded to the fixing block. The fixing block is fixed on the mounting base.

[0012] Preferably, the inner side of the lid is provided with a protrusion that is adapted to the opening end of the extended box, so that when the lid is closed, the protrusion extends into the extended box, thereby enhancing the sealing of the connection between the lid and the extended box.

[0013] The box cover is provided with a placement groove, and multiple through holes are arranged at intervals on the bottom of the placement groove.

[0014] The drying assembly includes a sealing cap and a breathable drying bag. The breathable drying bag contains a desiccant and is placed in a slot in the lid. The slot in the lid has a connecting protrusion at its opening, and the sealing cap is threaded onto the connecting protrusion.

[0015] Furthermore, a pad is provided at the bottom of the main housing to prevent the main housing from contacting the ground, thereby effectively isolating it from ground moisture.

[0016] The beneficial effects of this utility model are:

[0017] The adjustment mechanism designed in this utility model greatly facilitates the operation of adjusting the storage space of the logistics box. The user only needs to turn the handle, and the screw will be driven to rotate through the meshing transmission of the first helical tooth and the second helical tooth, so that the moving block can move up and down. The support rod and the connecting block can drive the expansion box inside the main box to move up or down. The operation is convenient and easy to use.

[0018] This utility model adds a locking component, which locks the position of the adjustment mechanism after adjustment by adjusting the screw movement limit block to move forward and engage with the groove of the retaining ring on the central shaft, making the box formed after the expansion box moves more stable in use.

[0019] This utility model adds a moisture-proof drying component to the box lid. During the turnover and transportation of the logistics box, the moisture inside the box will enter the placement slot through the through hole. The desiccant in the placement slot will dry the inside of the box, reducing the problem of the quality of the goods affected by moisture during transportation. In addition, the threaded sealing cover at the opening of the placement slot can also be easily opened to replace the desiccant inside. Attached Figure Description

[0030] Example 1

[0031] As shown in the figure, the expansion box 2 is located in the telescopic groove provided on the main box 1. The top opening end of the expansion box 2 is hinged to the box cover 3. The box cover 3 is provided with a handle 31 for opening and closing. A pad 11 is provided at the bottom of the main box 1. The pad 11 prevents the main box 1 from contacting the ground, thereby effectively isolating the ground moisture.

[0032] like Figure 2An adjustment mechanism is installed on the rear side of the main housing. The mounting base 41 in the adjustment mechanism is fixedly mounted on the outer wall of the main housing 1. A screw 44 is mounted in the movable groove on the mounting base 41 via a bearing. The lower end of the screw 44 is connected to the handle 42 via a transmission assembly. Figure 3 As shown in the cross-sectional view, the transmission assembly consists of a first helical tooth 431 and a second helical tooth 432. A handle 42 is fixedly mounted at one end of the central shaft of the first helical tooth 431. The first helical tooth 431 meshes with the second helical tooth 432, and the second helical tooth 432 is connected to the lower end of the screw 44. This allows the screw 44 to rotate when the handle 42 is rotated, as the meshing of the first and second helical teeth 431 causes the screw 44 to rotate accordingly. A moving block 45 is threaded onto the screw 44. The moving block 45 is fixedly connected to a support rod 46 by screws. The upper end of the support rod 46 is connected to a connecting block 21 fixedly mounted on the expansion housing 2.

[0033] like Figure 3 As shown, a retaining ring 66 is provided on the central shaft 4311 of the first helical tooth 431. A retaining groove 65 is arranged on the outer ring of the retaining ring 65. The limiting block 64 is adapted to the groove 66. The limiting block 64 is fixed on the limiting plate 63. One end of the adjusting screw 61 in the locking assembly is connected to the limiting plate 63 through a bearing, and the other end is threaded to the fixing block 62. The fixing block 62 is fixed on the mounting base 41. By operating the adjusting screw 61, the limiting block 64 is moved forward and engaged in the groove 66 of the retaining ring 65 on the central shaft 4311 to lock the position of the adjusting mechanism after adjustment, so that the box formed after the expansion box 2 moves is more stable in use.

[0034] like Figure 6 The inner side of the lid 3 is provided with a protrusion 33, which is adapted to the opening end of the expansion box 2, so that when the lid 3 is closed, the protrusion 33 extends into the expansion box 2, thereby enhancing the sealing of the connection between the lid 3 and the expansion box 2.

[0035] like Figure 4 and 5 The box cover 3 is provided with a placement groove 32. Multiple through holes 321 are arranged at intervals on the bottom of the placement groove 32. The breathable drying bag 52 in the drying assembly is placed in the placement groove 32 of the box cover 3. The breathable drying bag 52 contains desiccant. A connecting protrusion 33 is provided at the opening of the placement groove 32 of the box cover 3, so that the sealing cover 51 is threaded onto the connecting protrusion 33.

[0036] Example 2

[0037] In use, the size of the storage space of the logistics box can be adjusted according to practical needs through the adjustment mechanism. During adjustment, the user first operates the adjusting screw 61 in the locking assembly to move the limiting block 64 out of the slot 66 of the retaining ring 65, thereby releasing the lock on the central shaft 4311. Then, by rotating the handle 42, the screw 44 is driven to rotate through the meshing transmission of the first helical tooth 431 and the second helical tooth 432, causing the moving block 45 to move up and down. Through the support rod 46 and the connecting block 21, the extended box 2 inside the main box 1 is moved up or down, thereby completing the adjustment of the storage space size of the box. The operation is convenient and easy to use.

[0038] Furthermore, after adjusting the movement of the expansion housing 2, the limit block is reset by adjusting the screw 62 and moves forward to engage with the groove 66 of the retaining ring 65 on the central shaft 4311 to lock the position of the adjustment mechanism, making the housing formed after the expansion housing 2 moves more stable in use.

[0039] Example 3

[0040] During the turnover and transportation of the logistics box, the moisture inside the box will enter the placement slot 32 through the through hole 321. The desiccant in the placement slot 32 will dry the inside of the box, reducing the problem of the quality of the items affected by moisture during transportation. In addition, the sealing cover 51 is threaded at the opening of the placement slot 32, which also makes it easy to open the sealing cover 51 to replace the desiccant inside.
