Technical Field
[0001] This utility model relates to a drawer box, belonging to the field of drawer box technology. Background Technology
[0002] In most scenarios, such as transportation and storage, drawer boxes are needed to store and organize items.
[0003] Most drawer-style storage boxes on the market have a fixed number of drawers. The height and number of drawers are determined at the factory and cannot be flexibly increased, decreased, or adjusted according to actual storage volume or product category needs. Although some products have removable multi-drawer units, disassembly and assembly are inconvenient, and the lack of guide rails and limiting structures makes the drawers prone to instability when sliding out. Furthermore, the box body does not consider heat dissipation and ventilation requirements, which can easily lead to moisture or high temperature accumulation in storage environments that require good ventilation, such as for pharmaceuticals, electronic components, and food. The bottom of the box also rarely has a special reinforcing design, making it prone to deformation when bearing heavy objects.
[0004] Therefore, a drawer box needs to be designed to solve the problems of traditional boxes, such as the inability to adjust the height of the drawers, the limited space inside the drawers, unstable sliding, and poor ventilation. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a drawer box that solves the problems of traditional boxes not being able to adjust the height of the drawer, the space inside the drawer, unstable sliding, and poor ventilation.
[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a drawer box, including an outer shell and a drawer, wherein the drawer is disposed inside the outer shell.
[0007] The outer casing includes a rectangular casing with an opening on its long side, and the drawer is slidably disposed on the opening side of the outer casing via a sliding assembly;
[0008] The number of drawers includes at least one, the height of the drawers is adjusted according to the number of drawers, the assembled drawers can cover the side of the outer shell, and the shape of the assembled drawers is consistent with the shape of the inner side of the outer shell;
[0009] The sliding assembly includes a slide rail and a slide plate. The slide rail is disposed on the bottom side of the drawer, and the slide plate is disposed on the side of the outer casing. Multiple slide plates are disposed inside the outer casing. The drawers can be connected to the outer casing via the sliding assembly when there are different numbers of them.
[0010] Preferably, the slide rail is the bottom boss of the drawer; the slide plate is fixed to the inside sides of the outer casing by bolts.
[0011] Preferably, the slide plate has a slide groove on its surface, and the slide groove is located at the bottom, middle, one-third and two-thirds of the inner side of the slide plate; the slide rail has a protrusion at its end, and the slide groove has a baffle at its front end, so that the slide groove cannot completely detach from the slide rail.
[0012] Preferably, the drawer is provided with a baffle, and there are up to four baffles, which can divide the inner space of the drawer into two, three or four parts evenly.
[0013] Preferably, the drawer has multiple mounting slots on its long side inside, which can fix the baffle.

[0028] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1
[0029] like Figures 1-6 As shown, a drawer box includes an outer shell 1 and a drawer 2, with the drawer 2 disposed inside the outer shell 1. The outer shell 1 is a rectangular shell with an opening along its long side, and the drawer 2 is disposed on the side of the outer shell 1 via a sliding assembly 3.
[0030] In this embodiment, the number of drawers 2 is at least one, and the height of drawers 2 is adjusted according to the number of drawers 2. When there is one drawer 2, the height of drawer 1 is the same as the height of the inner side of the opening of the outer shell 1; when there are two drawers 2, the height of a single drawer 2 is half the height of the inner side of the opening of the outer shell 1, and the two drawers 2 can be arranged vertically, with the height of the two stacked drawers 2 being the same as the height of the inner side of the opening of the outer shell 1; when there are three drawers 2, the height of a single drawer 2 is one-third the height of the inner side of the opening of the outer shell 1, and the three drawers 2 can be arranged vertically, with the height of the three stacked drawers 2 being the same as the height of the inner side of the opening of the outer shell 1. This ensures that the outer shell 1 can accommodate different numbers of drawers 2; there are no gaps between the top and bottom of the drawers 2 and the outer shell 1.
[0031] In this embodiment, the outer shell 1 is approximately rectangular in shape and specifically comprises upper and lower base plates, a long side wall, and two short side walls connected together. The upper base plate is connected to the long side wall and the two short side walls by snap-fit connections, and the upper base plate can be removed.
[0032] Inside the two short sidewalls of the outer casing 1, a sliding plate 32 is fitted together. The sliding plate 32 is connected to the short sidewalls of the outer casing 1 by bolts. The sliding plate 2 and the outer casing 1 are two parts that can be disassembled and assembled by bolts.
[0033] The bottom of the outer shell 1 is provided with reinforcing ribs, which can improve the rigidity of the bottom plate of the outer shell 1 and prevent the outer shell 1 from deforming under heavy load.
[0034] Reference Figures 1-4 , Figure 6 Drawer 2 is a rectangular box with an opening at the top. The interior of drawer 2 can accommodate a certain amount of space. The length and width of the bottom plate of drawer 2 are the same as the length and width of the bottom plate inside the outer shell 1. The height of drawer 2 is adjusted according to the number of drawers 2, ensuring that the stacked height of all drawers 2 is the same as the inner height of the outer shell 1.
[0035] Drawer 2 can be connected to outer casing 1 via sliding component 3, and one long side of drawer 2 can be pulled out or retracted from outer casing 1. A notch is provided in the middle of the side of drawer 2 located at the opening of outer casing 1, allowing the operator to operate drawer 2 through the notch. Slide rails 31 are provided at the bottom of the short sides of drawer 2. The slide rails 31 are rectangular bosses in shape and can horizontally support the weight of the drawer.
[0036] In this embodiment, the drawer 2 can be fitted with or detached baffles 21. Multiple mounting slots 22 are provided along the inner long side of the drawer 2. The mounting slots 22 are symmetrically arranged in an "L" shape, with an opening in the center. The baffles 21 have an "I" shape and can be inserted into the mounting slots 22. The mounting slots 22 on both sides of the drawer 2 can lock the baffles 21 in place.
[0037] In this embodiment, the baffle 21 can divide the interior space of the drawer 2 into several equal areas for convenient classification and storage. The baffle 21 can divide the interior space of the drawer 2 into two, three, or four equal parts, that is, the mounting groove 22 is set at the middle, one-third, two-thirds, one-quarter, or three-quarters of the long side of the drawer 2.
[0038] The sliding assembly 3 includes a slide rail 31 and a slide plate 32. The slide rail 31 is a protrusion on the bottom of the short side of the drawer 2, and all different drawers 2 are equipped with a slide rail 31 at the bottom. The slide rail 31 can slide with the slide groove 321 on the slide plate 32, so that the drawer 2 can be pulled out or retracted from the outer shell 1.
[0039] Reference Figures 2-6The sliding plate 32 is connected to the outer shell 1 by bolts. Sliding plates 32 are provided on both short sides of the inner side of the outer shell 1, covering the entire inner short sides of the outer shell 1. Sliding grooves 321 are provided on the sliding plates 32. The sliding grooves 321 are grooves, and a baffle is provided on the side near the opening of the outer shell 1. The slide rail 31 can slide within the sliding grooves 321.
[0040] The drawer 2's slide rail 31 has a protrusion 311 on the side away from the opening of the outer casing 1. (See reference) Figure 6 When drawer 2 is pulled out, the protrusion 311 on the slide rail 31 can abut against the baffle on the slide groove 321 to prevent drawer 2 from falling off the slide groove 321. When drawer 2 is pushed in from the outside, the slide rail 31 and the slide groove 321 cooperate to ensure that drawer 2 is aligned with the outer shell 1 until drawer 2 is closed.
[0041] The slide plate 32 is provided with multiple slide grooves 321, as shown in the figure. Figure 5 The slide rails 321 are located at the bottom, middle, one-third, and two-thirds of the slide rail plate 32. When there is only one drawer 2, the slide rail 31 is connected only to the bottom slide rail 321, and the height of the drawer 2 is the height of the side opening of the outer shell 1. When there are two drawers 2, drawers 2 are provided on the bottom and middle slide rails 321, and the height of a single drawer 2 is half the height of the side opening of the outer shell 1. The two drawers 2 can be pulled out separately without affecting each other. When there are three drawers 2, drawers 2 are provided on the bottom, one-third, and two-thirds slide rails 321, and the height of a single drawer 2 is one-third the height of the side opening of the outer shell 1. The three drawers 2 can be pulled out separately without affecting each other.
[0042] In this embodiment, both the outer shell 1 and the drawer 2 adopt a hollow structure to facilitate ventilation. Patterned perforations are designed on the bottom of both the outer shell 1 and the drawer 2. When items are placed inside the drawer 2, the hollow design prevents items from falling through the gaps. The hollow structure at the bottom of the outer shell 1 ensures that airflow can pass through the outer shell 1 into the interior of the drawer 2, facilitating ventilation and breathability of stored items.
[0043] Reference Figure 2 , Figure 4 The bottom sides of the outer shell 1 have notches, and the robotic arm can reach into the notches to pick up the entire drawer box.
[0044] The bottom of both the outer shell 1 and the drawer 2 is equipped with reinforcing ribs to strengthen the bottom of the outer shell 1 and the drawer 2, increase the load-bearing capacity, and prevent the box from deforming.
