Description

Technical Field

[0001] This application relates to the field of storage box technology, and in particular to a storage box. Background Technology

[0002] Currently, common storage boxes on the market typically consist of a box body and a pull-out drawer. For ease of transport, these boxes are usually designed to be detachable, meaning the top cover, bottom cover, and side panels are assembled into the box body using snap-fit ​​mechanisms. However, existing quick-assembly structures often use simple snap-fit ​​connections, such as elastic hooks and slots. Frequent disassembly and reassembly, especially if forcefully disassembled, can easily deform the snaps, affecting the overall structural stability.

[0003] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0004] In view of the above problems, this utility model proposes a storage box, which aims to solve the technical problem that the existing buckle connection is prone to buckle deformation during frequent disassembly and assembly.

[0005] To achieve the above objectives, the storage box proposed in this utility model includes: a box body and a drawer; The box body includes a detachably connected upper cover plate, a lower cover plate, and multiple side panels. Any of the side panels can be detachably connected to the upper cover plate and the lower cover plate via a quick-release structure. The multiple side panels, together with the upper cover plate and the lower cover plate, form a pull-out space with an opening on one side. The drawer is slidably placed within the pull-out space via the opening. The drawer includes a detachably connected bottom plate and multiple side plates, any one of which is detachably connected to the bottom plate. The multiple side plates are sequentially spliced ​​end to end by the quick-release structure to enclose and form a receiving cavity. The lower cover plate has a slide rail, and the bottom plate is slidably connected to the slide rail; The quick-release structure includes an anti-detachment structure, which includes a slot and a tongue. The slot is located on one plate, and the tongue is located on another plate. The slot has an insertion section and a locking section. The width of the insertion section is greater than the width of the locking section. The tongue is inserted into the insertion section and slides to the locking section so that the two plates are connected at the upper limit in the insertion direction of the tongue.

[0006] In one embodiment, the quick-release structure further includes a limiting structure, which includes a locking block and a locking hole. The locking hole extends along the sliding direction of the tongue, and a guide locking block is provided in the middle of the locking hole.

The guide locking block has a guide slope that extends from the insertion section to the locking section and is inclined outward. In the sliding direction of the tongue, the engaging block has a first inclined surface and a second inclined surface facing away from each other. In the insertion direction of the tongue, the distance between the first inclined surface and the second inclined surface gradually increases from the free end to the connecting end. The first inclined surface and the guide inclined surface cooperate in the sliding direction of the tongue.

[0007] In one embodiment, one of the top wall of the enclosure and the surface of the upper cover plate is provided with the protruding tongue, and the other is provided with the slot; The bottom wall of the enclosure and the surface of the lower cover plate are provided with the protruding tongue and the other is provided with the slot; The quick-release structure between the lower cover and the surrounding panel is located on the outside of the drawer. The drawer has a guide bar that is slidably embedded in the slide rail, and the slide rail has a baffle. The end of the guide bar away from the opening can be stopped by the baffle.

[0008] In one embodiment, the side panel in the left-right direction is defined as the first side panel, and the left-right direction is perpendicular to the pull-out direction; The first side plate includes a base plate and a flange formed by folding inward from the bottom of the base plate, and the bottom plate is snapped into the flange; The guide strip protrudes from the bottom wall of the flange and is located at the end of the flange away from the substrate, so that the substrate is disposed adjacent to the enclosure.

[0009] In one embodiment, the plurality of enclosure panels include four corner panels, which are located at the corners of the box body, with adjacent corner panels spaced apart.

[0010] In one embodiment, one of the upper cover plate and the surrounding plate is provided with the protruding tongue, and the other is provided with the slot; One of the lower cover plate and the surrounding plate is provided with the protruding tongue, and the other is provided with the slot; The side panel in the left-right direction is defined as the first side panel, and the surrounding panel in the left-right direction is defined as the first surrounding panel, wherein the left-right direction is perpendicular to the pull-out direction; The quick-release structure is located below the drawer, which overlaps the slide rail so that the first side panel is positioned adjacent to the first enclosure panel.

[0011] In one embodiment, the lower cover plate is sandwiched between two opposing first enclosure plates, and two slide rails are provided at opposite ends of the lower cover plate. The first enclosure plate is provided with the tongue, and the slide rails are provided with the slots. Each of the slide rails has a receiving groove, and the protruding tongue is embedded in the receiving groove.

[0012] In one embodiment, the enclosure defined in the pull-out direction is a second enclosure, and the side plate defined in the pull-out direction is a second side plate. The second enclosure includes a plate body and a connecting part. The connecting part protrudes from the inner wall surface of the plate body, and the plate body covers the ends of the lower cover plate, the two first enclosure plates, and the upper cover plate along the pull-out direction. The surface of the second side plate abuts against the end face of the connecting part, so that the second side plate and the plate body enclose and form an installation space; The connection between the first enclosure and the connecting part is located within the installation space.

[0013] In one embodiment, the connecting portion has an abutting wall surface in the left-right direction, the abutting wall surface and the plate surface of the plate form an embedding groove, and the end of the first enclosure plate is embedded in the embedding groove so that the outer wall surface of the first enclosure plate and the end surface of the plate smoothly transition.

[0014] In one embodiment, the first enclosure includes a body and a joint that are connected to each other, the joint being fitted into the fitting groove, and the thickness of the joint being greater than the thickness of the body; The side wall of the connecting part is provided with a locking groove, and the inner wall surface of the joint is provided with a locking member, which is engaged with the locking groove.

[0015] In one embodiment, the inner wall surfaces of the upper cover plate, the lower cover plate, the plurality of surrounding plates, the bottom plate, and the plurality of side plates are all provided with digital markings.

[0016] Existing storage boxes typically lack drawers or have non-removable drawers, resulting in a large volume during transport. This invention addresses this by incorporating a quick-assembly structure with anti-detachment features between the top and bottom covers, side panels, and bottom panels. This allows for rapid assembly and disassembly of the components, reducing volume during shipping and saving space when not in use. Secondly, a slot structure with different widths for the insertion and locking sections provides guidance and locking during assembly. The tongue, after sliding to the locking section, is restrained by the slot wall, effectively preventing detachment. Compared to existing structures relying solely on elastic hooks and slots, which are prone to deformation from repeated assembly and disassembly, this invention improves the deformation resistance and durability of the connection points through a sliding locking mechanism, ensuring the storage box maintains structural stability even after multiple assemblies. Furthermore, a slide rail on the upper surface of the bottom cover reduces friction between the drawer and the box, making the drawer easier to pull out. Attached Figure Description

[0022] This utility model proposes a storage box 100.

[0023] In this embodiment of the utility model, please refer to Figures 1 to 17 The storage box 100 includes a box body 10 and a drawer 20; The box body 10 includes a detachably connected upper cover plate 11, a lower cover plate 12, and multiple side panels 13. Any side panel 13 is detachably connected to the upper cover plate 11 and the lower cover plate 12 via a quick-release structure 30. The multiple side panels 13, together with the upper cover plate 11 and the lower cover plate 12, enclose a pull-out space 10 with an opening 10 on one side. The drawer 20 is slidably placed in the pull-out space 10 via the opening 10. The drawer 20 includes a detachably connected bottom plate 22 and multiple side panels 21. Any side panel 21 is detachably connected to the bottom plate 22. The multiple side panels 21 are sequentially spliced ​​end to end via the quick-release structure 30 to enclose a receiving cavity 20a. The lower cover plate 12 has a slide rail 121, and the bottom plate 22 is slidably connected to the slide rail 121. The quick-release structure 30 includes an anti-detachment structure 31, which includes a slot 311 and a tongue 312. The slot 311 is located on one plate, and the tongue 312 is located on another plate. The slot 311 has a plug-in section 3111 and a locking section 3112. The width of the plug-in section 3111 is greater than the width of the locking section 3112. The tongue 312 is inserted into the plug-in section 3111 and slides to the locking section 3112 so that the two plates are connected in the insertion direction of the tongue 312.

[0024] In this embodiment, the storage box 100 includes a box body 10 and a drawer 20. The box body 10 includes a detachably connected upper cover plate 11, a lower cover plate 12, and multiple side panels 13. The upper and lower ends of any side panel 13 are detachably connected to the upper cover plate 11 and the lower cover plate 12 respectively via quick-release structures 30. The multiple side panels 13 are sequentially spliced ​​end to end, and together with the upper cover plate 11 and the lower cover plate 12, they enclose a pull-out space 10 with an opening 10 on one side. In other words, the upper cover plate 11, the lower cover plate 12, and the multiple side panels 13 are all plate-shaped, and each plate of the box body 10 can be detachably connected.

[0025] The drawer 20 can be slidably placed in the pull-out space 10 through the opening 10. The drawer 20 includes a bottom plate 22 and multiple side plates 21. Any side plate 21 can be detachably connected to the bottom plate 22. The multiple side plates 21 are spliced ​​end to end in sequence and connected to each other by a quick-release structure 30 to form a receiving cavity 20a, so that the user can easily disassemble or replace the drawer 20 according to storage needs.

[0026] The upper surface of the lower cover plate 12 is provided with a slide rail 121, and the lower surface of the base plate 22 is slidably connected to the slide rail 121. The slide rail 121 may or may not have a groove, and there is no limitation on this. When the groove is not provided, the drawer 20 can overlap the slide rail 121. Since the contact area between the slide rail 121 and the base plate 22 is small, the friction between the two can be reduced, so that the drawer 20 can maintain smooth movement when it is pulled out, improving the smoothness of use and structural stability.

[0027] To improve the connection reliability of the quick-release structure 30, the quick-release structure 30 includes an anti-detachment structure 31. The anti-detachment structure 31 includes a slot 311 disposed on one plate and a tongue 312 disposed on another plate. The slot 311 extends along the plate surface and has an insertion section 3111 and a locking section 3112, wherein the width of the insertion section 3111 is greater than the width of the locking section 3112. Preferably, the slot 311 can be configured as a "T"-shaped, barbed, or arc-shaped slot structure; correspondingly, the tongue 312 can be a "T"-shaped or "L"-shaped tongue, a beveled tongue, or a circular arc tongue. The slot 311 and the tongue 312 can be integrally injection molded onto the plate, or formed onto the plate by ultrasonic welding, screw fixing, or other methods. To avoid wear and tear caused by frequent disassembly and assembly, the panels can be made of polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), or wood-plastic composite materials; if higher strength is required, a metal sheet or glass fiber reinforcement layer can be embedded in the 135 position of the connection.

[0028] During assembly, the protruding tongue 312 is inserted into the slot 311 by the insertion section 3111 and slides along the extension direction of the slot 3111 to the locking section 3112. Because the locking section 3112 is narrow, after the protruding tongue 312 slides in, the locking section 3112 holds the side of the protruding tongue 312 in place, preventing it from coming out due to external force during use, thus achieving a reliable limiting connection between the two plates in the insertion direction. For example, the side plate 13 and the top cover plate 11 are connected by a quick-connect structure 30, meaning that one of the side plate 13 and the top cover plate 11 has a protruding tongue 312, and the other has a slot 311. The same applies to the connection between other two plates via the quick-connect structure 30.

[0029] In the prior art, storage boxes 100 typically do not have drawers 20 or the drawers 20 are usually non-removable, which results in a large volume during transportation. This utility model provides a quick-assembly structure 30 with anti-detachment function between the upper cover plate 11, lower cover plate 12 and surrounding plate 13, and between the side plate 21 and bottom plate 22, which allows for quick assembly and disassembly of the various plates, making it easier to reduce the volume during factory transportation. When the storage box 100 is not needed, it can save space for storage. Secondly, by setting a slot 311 structure with different widths for the insertion section 3111 and the locking section 3112, the assembly process is guided and locked. After the tongue 312 slides to the locking section 3112, it is limited by the wall of the slot 311, thereby effectively preventing it from falling off. Compared to existing technologies that rely solely on elastic hooks and slots 311 for connection and are prone to deformation due to repeated disassembly and assembly, this invention improves the deformation resistance and durability of the connecting part 135 through a sliding locking mechanism, ensuring that the storage box 100 maintains good structural stability after multiple assembly. Furthermore, by providing a slide rail 121 on the upper surface of the lower cover plate 12, the friction between the drawer 20 and the box body 10 is reduced, making the drawer 20 slide out of the box body 10 more smoothly.

[0030] In one embodiment, reference is made to Figures 3 to 6 The quick-release structure 30 also includes a limiting structure 32, which includes a locking block 321 and a locking hole 322. The locking hole 322 extends along the sliding direction of the tongue 312, and a guide locking block 323 is provided in the middle of the locking hole 322. The guide locking block 323 is used to limit and abut against the locking block 321. The guide locking block 323 has a guide inclined surface 324, which extends from the insertion section 3111 to the locking section 3112 and is inclined outward. In the sliding direction of the tongue 312, the locking block 321 has a first inclined surface 322 and a second inclined surface 323 facing away from each other. In the insertion direction of the tongue 312, the distance between the first inclined surface 322 and the second inclined surface 323 gradually increases from the free end to the connecting end. The first inclined surface 322 and the guide inclined surface 324 cooperate in the sliding direction of the tongue 312.

[0031] In this embodiment, the quick-release structure 30 further includes a limiting structure 32. The limiting structure 32 includes a locking block 321 disposed on one plate and a locking hole 322 disposed on another plate. The locking hole 322 extends along the sliding direction of the tongue 312, and a guide locking block 323 is provided in the middle of the locking hole 322. The guide locking block 323 is used to form a limiting abutment with the locking block 321 during the sliding process to prevent over-insertion or loosening. Specifically, the guide locking block 323 has a guide slope 324, which extends from the insertion section 3111 to the locking section 3112 and is inclined outward. Through the setting of the guide slope 324, the locking block 321 can be gradually inserted into the locking hole 322 during the assembly process, realizing smooth guidance and gradual locking. Further, in the sliding direction of the tongue 312, the locking block 321 has a first slope 322 and a second slope 323 facing opposite directions. The distance between the first inclined surface 322 and the second inclined surface 323 gradually increases from the free end to the connecting end. When the tongue 312 slides along the insertion direction, the first inclined surface 322 gradually contacts and engages with the guide inclined surface 324, thereby achieving the dual functions of limiting guidance and buffering engagement. It should be noted that "inner" refers to the side located near the receiving cavity 20a inside the drawer 20, and "outer" refers to the side located near the outer wall of the enclosure 13. The free end refers to the unconnected end, and the connecting end refers to the end where the engaging block 321 is connected to the plate 134.

[0032] During assembly, the operator only needs to align the protruding tongue 312 with the insertion section 3111 of the slot 311 and push it inward. Guided by the guide slope 324, the locking block 321 automatically enters the locking hole 322. After the locking block 321 passes the guide locking block 323, the guide slope 324 and the first slope 322 form mutual abutment, providing a reverse limiting force, thereby preventing the protruding tongue 312 from loosening or falling out under the action of external force, achieving a double locking effect.

[0033] By setting a limiting structure 32 on the basis of the anti-detachment structure 31, the anti-detachment structure 31 is used to prevent detachment in the insertion direction, and the limiting structure 32 is used to limit excessive insertion or detachment in the sliding direction. The two work together to limit the installation of adjacent plates in both the insertion and sliding directions, making the connection between the plates tighter. In addition, the locking block 321 has a first inclined surface 322 and a second inclined surface 323. During installation, the first inclined surface 322 cooperates with the guide inclined surface 324 of the guide locking block 323. During disassembly, the second inclined surface 323 acts as a guide, making disassembly and assembly more convenient and avoiding damage during disassembly and assembly.

[0034] In the first embodiment, referring to Figures 1 to 9 One of the top wall of the enclosure 13 and the surface of the upper cover 11 is provided with a protruding tongue 312, and the other is provided with a slot 311; one of the bottom wall of the enclosure 13 and the surface of the lower cover 12 is provided with a protruding tongue 312, and the other is provided with a slot 311; the quick-release structure 30 between the lower cover 12 and the enclosure 13 is located on the outside of the drawer 10; the drawer 20 has a guide bar 214, which is slidably embedded in the slide rail 121, and the end of the slide rail 121 away from the opening 10 has a baffle 1211; the guide bar 214 can be limited and stopped against the baffle 1211 to limit the drawer 20 from exceeding the pull-out space 10.

[0035] In this embodiment, one of the top wall of the surrounding plate 13 and the surface of the upper cover plate 11 is provided with a protruding tongue 312, and the other is provided with a slot 311; one of the bottom wall of the surrounding plate 13 and the surface of the lower cover plate 12 is provided with a protruding tongue 312, and the other is provided with a slot 311. It should be noted that the plate surface usually refers to the planar surface of the plate, and here it refers to the unfolded surface of the front or back of the plate. For example, for a rectangular side plate 21, its "plate surface" is usually the side with the largest area, that is, the front or back; for an arc-shaped side plate 21, its plate surface refers to the outer or inner surface of the arc-shaped plate, that is, the main unfolded surface formed by unfolding along the curvature.

[0036] Preferably, the quick-release structure 30 is located to the side of the slide rail 121 of the lower cover plate 12, so that the quick-release structure 30 does not interfere with the sliding structure of the drawer 20, thereby avoiding friction and jamming during the pulling process. The drawer 20 is provided with a guide strip 214 extending along the pulling direction, and the guide strip 214 is slidably embedded in the slide rail 121. The cross-section of the guide strip 214 can be T-shaped, rectangular or semi-circular to adapt to different shapes of slide rails 121. The guide strip 214 and the base plate 22 can be integrally formed, or it can be fixed to the lower surface of the base plate 22 by threaded connection. The guide strip 214 and the slide rail 121 can achieve smooth guidance of the drawer 20 through clearance fit or sliding fit, while limiting the vertical wobbling of the drawer 20, ensuring smooth pulling and positioning accuracy. Secondly, a baffle 1211 is provided at the end of the slide rail 121 away from the opening 10. The baffle 1211 extends in the left and right direction. When the end of the guide bar 214 away from the opening 10 slides to the limit position, it can abut against the baffle 1211 to prevent the drawer 20 from being pushed in too much and exceeding the pull-out space 10.

[0037] Further, the side plate 21 in the left-right direction is defined as the first side plate 211, and the left-right direction is perpendicular to the pulling direction; the first side plate 211 includes a base plate 212 and a flange 213 formed by folding inward from the bottom of the base plate 212, and the bottom plate 22 is snapped into the flange 213; the guide strip 214 protrudes from the bottom wall of the flange 213 and is located at the end of the flange 213 away from the base plate 212, so that the base plate 212 is disposed adjacent to the surrounding plate 13.

[0038] In this embodiment, the drawer 20 side panel 21 defined in the left-right direction is the first side panel 211, which is arranged perpendicular to the pull-out direction. The first side panel 211 includes a base plate 212 and a flange 213 formed by folding inward from the bottom of the base plate 212. The flange 213 extends along the pull-out direction and is bent toward the inside of the storage box 100 to enhance structural rigidity and form a limiting mounting surface for the bottom plate 22.

[0039] The side edge of the base plate 22 engages with the limiting groove inside the flange 213, thereby achieving a stable assembly connection between the base plate 22 and the first side plate 211. This structure forms a complete support frame at the bottom of the drawer 20, ensuring the load-bearing capacity of the drawer 20 while facilitating assembly and disassembly.

[0040] Furthermore, the guide strip 214 can be integrally injection molded with the flange 213, or it can be retrofitted or bonded. The guide strip 214 protrudes from the bottom wall of the flange 213 and is located at the end of the flange 213 away from the substrate 212, that is, the free end of the flange 213 is folded downward to form the guide strip 214, so that the substrate 212 is positioned adjacent to the surrounding plate 13. When the drawer 20 is fully inserted into the pull-out space 10, the substrate 212 of the first side plate 211 is arranged opposite to the inner wall of the surrounding plate 13, thereby effectively preventing the drawer 20 from wobbling left and right during the pull-out process. If the guide strip 214 extends from the bottom of the substrate 212, at least a portion of the slide rail 121 will block the substrate 212 from being adjacent to the surrounding plate 13, thereby causing the drawer 20 to wobble left and right during the pull-out process. In some embodiments, to further improve the guiding performance, a wear-resistant layer or rolling balls can be provided on the bottom surface of the guide strip 214 to make the pull-out process smoother.

[0041] In one embodiment, the plurality of enclosure panels 13 include four corner panels 131, which are located at the corners of the box body 10, and adjacent corner panels 131 are spaced apart.

[0042] In this embodiment, the multiple side panels 13 include four corner panels 131. The four corner panels 131 are respectively located at the four corners of the box body 10, with adjacent corner panels 131 spaced apart. The two sides of each corner panel 131 are detachably connected to the upper cover plate 11 and the lower cover plate 12, thereby forming a frame-like support structure at the four corners of the box body 10. In this way, the box body 10 achieves left and right limiting of the drawer 20 at the four corners. Simultaneously, due to the gaps between adjacent corner panels 131, the box body 10 has a hollow layout, effectively reducing the overall weight without affecting strength and stability. This hollow structure not only helps reduce material usage and production costs but also reduces weight burden during transportation, thereby reducing transportation costs.

[0043] In the second embodiment, refer to Figures 10 to 14 One of the upper cover plate 11 and the side plate 13 is provided with a protruding tongue 312 and the other with a slot 311; one of the lower cover plate 12 and the side plate 13 is provided with a protruding tongue 312 and the other with a slot 311; the side plate 21 defined in the left-right direction is the first side plate 211, and the side plate 13 in the left-right direction is the first side plate 132, and the left-right direction is perpendicular to the pull-out direction; the quick-release structure 30 between the lower cover plate 12 and the side plate 13 is located below the drawer 20, and the drawer 20 is connected to the slide rail 121 so that the first side plate 211 is set adjacent to the first side plate 132.

[0044] In this embodiment, one of the surfaces of the upper cover plate 11 and the surrounding plate 13 is provided with a protruding tongue 312, and the other is provided with a slot 311; one of the surfaces of the lower cover plate 12 and the surrounding plate 13 is provided with a protruding tongue 312, and the other is provided with a slot 311. In this way, the upper cover plate 11, the surrounding plate 13, and the lower cover plate 12 can all be quickly assembled and disassembled through the same quick-installation structure 30, thereby improving assembly consistency and structural modularity.

[0045] The quick-release structure 30 is located below the drawer 20, ensuring that the quick-release connection area does not interfere with the sliding space of the drawer 20. Furthermore, the bottom of the drawer 20 rests on the slide rail 121 of the lower cover plate 12, allowing the first side panel 211 to be positioned adjacent to the first surrounding panel 132, effectively preventing the drawer 20 from wobbling left and right during operation. Secondly, this layered arrangement makes the spatial layout more defined and compact.

[0046] Furthermore, the lower cover plate 12 is sandwiched between two opposing first enclosure plates 132. Two slide rails 121 protrude upwards from opposite ends of the lower cover plate 12. The first enclosure plate 132 is provided with a tongue 312, and the slide rail 121 is provided with a slot 311. Each slide rail 121 has a receiving groove 122, and the tongue 312 is embedded in the receiving groove 122.

[0047] In this embodiment, the lower cover plate 12 is sandwiched between two opposing first enclosure plates 132, thus preventing the lower cover plate 12 from protruding beyond the first enclosure plates 132 and making the storage box 100 more aesthetically pleasing. Two upward-protruding slide rails 121 are provided at opposite ends of the lower cover plate 12 to provide guiding support for the drawer 20 and for detachable connection with the first enclosure plates 132. The first enclosure plates 132 are provided with tabs 312, and the slide rails 121 are provided with slots 311; the two are assembled and connected through the cooperation of the tabs 312 and the slots 311.

[0048] The top wall of any slide rail 121 is recessed downwards to form a receiving groove 122, and the protruding tongue 312 is embedded in the receiving groove 122. In this way, the protruding tongue 312 can be hidden in the receiving groove 122, avoiding the exposed structure from the appearance and improving the overall aesthetics and sealing performance. Moreover, since the top wall of the slide rail 121 is recessed downwards, the contact area between the slide rail 121 and the bottom of the drawer 20 is correspondingly reduced, thereby effectively reducing the sliding friction resistance and making the drawer 20 slide out more smoothly.

[0049] In one embodiment, the enclosure 13 defined in the pull-out direction is the second enclosure 133, and the side plate 21 defined in the pull-out direction is the second side plate 215. The second enclosure 133 includes a plate body 134 and a connecting portion 135. The connecting portion 135 protrudes from the inner wall surface of the plate body 134. The plate body 134 covers the ends of the lower cover plate 12, the two first enclosure plates 132, and the upper cover plate 11 along the pull-out direction. The plate surface of the second side plate 215 abuts against the end face of the connecting portion 135 so that the second side plate 215 and the plate body 134 enclose each other to form an installation space 216. The connection between the first enclosure plate 132 and the connecting portion 135 is located within the installation space 216.

[0050] In this embodiment, the second enclosure 133 includes a plate body 134 and a connecting portion 135. The connecting portion 135 protrudes from the inner wall surface of the plate body 134 and is used for assembly connection with adjacent structures. The plate body 134 covers the ends of the lower cover plate 12, the two first enclosure plates 132 and the upper cover plate 11 along the pull-out direction, thereby making the box body 10 more concise and aesthetically pleasing.

[0051] Preferably, the surface of the first side plate 211 abuts against the end face of the connecting part 135, so that the side plate 21 and the plate body 134 together enclose and form an installation space 216; the connection between the first enclosure plate 132 and the connecting part 135 is located within the installation space 216, thereby ensuring stable assembly while hiding the connecting structure inside, improving the flatness and aesthetics of the overall appearance. Secondly, the surface of the second side plate 215 abuts against the end face of the connecting part 135, and the end face of the connecting part 135 forms a limiting surface, restricting the drawer 20 from continuing to extend further in the pulling direction. If the connecting part 135 is not provided, and the plate body 134 is directly snapped into the first enclosure plate 132, then after repeated impacts of the drawer 20, the plate body 134 is easily deformed due to its thinness.

[0052] Furthermore, the connecting portion 135 has an abutting wall surface 136 in the left-right direction, the abutting wall surface 136 and the plate surface of the plate body 134 form an embedding groove 137, and the end of the first surrounding plate 132 is embedded in the embedding groove 137 so that the outer wall surface of the first surrounding plate 132 and the end surface of the plate body 134 transition smoothly.

[0053] In this embodiment, the connecting portion 135 has an abutting wall surface 136 in the left-right direction, and the abutting wall surface 136 and the plate surface of the plate body 134 together form an embedding groove 137. The end of the first surrounding plate 132 is embedded in the embedding groove 137 so that the outer wall surface of the first surrounding plate 132 and the end face of the plate body 134 can be smoothly transitioned, thereby maintaining a stable assembly while forming a continuous, stepless overall appearance structure on the outer surface of the box body 10.

[0054] In one embodiment, the first enclosure 132 includes a body 1321 and a joint 1322 connected to each other. The joint 1322 is embedded in the insertion groove 137, and the thickness of the joint 1322 is greater than the thickness of the body 1321.
