Description
Technical Field
[0001] This utility model belongs to the field of logistics storage technology, specifically relating to a modular and scalable logistics storage device. Background Technology
[0002] Based on the current needs of the logistics and warehousing field, this utility model patent proposes a modular and scalable logistics storage device. Its technical background stems primarily from the following industry pain points: traditional logistics storage boxes generally suffer from rigid space utilization and insufficient scalability. Fixed-volume boxes are difficult to adapt to logistics items of varying sizes and types, leading to wasted storage space or the risk of mixed storage. Furthermore, when transportation volume surges, the limited capacity of a single box forces operators to frequently move multiple independent units, which is not only inefficient but also lacks a stable connection mechanism when multiple boxes are stacked or placed side-by-side, making them prone to displacement, collisions, or even tipping over during transportation, posing safety hazards. In addition, the lack of scientific internal partitioning makes item access inconvenient; weak overall anti-theft capabilities and poor mobility (especially when fully loaded) are also common drawbacks.
[0003] While existing technologies attempt to increase capacity through simple assembly or stacking designs, they often result in loose structures, unreliable connections, and neglect the synergistic optimization of flexible zone management and transportation safety. The lack of effective shock absorption within the enclosures makes delicate or fragile items susceptible to damage during transport. Poor heat dissipation can affect the storage quality of certain items (such as electronic devices or perishable goods). From a security perspective, traditional mechanical locks and key management are cumbersome, and overall protection needs improvement.
[0004] Against this backdrop, this utility model is dedicated to developing an integrated solution that combines modular free expansion, refined compartment management, highly stable connection, convenient movement and locking, and multiple security guarantees to meet the stringent requirements of modern logistics for the flexibility, security, and efficiency of storage devices. Utility Model Content
[0005] The purpose of this invention is to provide a modular and scalable logistics storage device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular and expandable logistics storage device, comprising an outer casing, expansion units, and an inner casing structure.
[0007] The outer casing is equipped with a T-shaped partition, which divides the inner cavity into three independent mounting slots;
[0008] The outer box is hinged to a lid on one side of its upper end, and the edge of the lid is provided with a lock body structure.
[0009] The expansion unit is symmetrically arranged on the left and right sides of the outer box, including a first fixing plate and a second fixing plate. The first fixing plate is fixed to the left side wall of the outer box, and the second fixing plate is fixed to the right side wall of the outer box.
[0010] The inner box structure includes two first inner boxes and one second inner box, which are slidably connected in three mounting slots respectively.
[0011] The second fixing plate has a slot on the side away from the outer casing, and the first fixing plate has a snap-fit part at the end away from the outer casing that matches the slot.
[0012] It should be noted in the solution that the four corners of the bottom of the outer box are equipped with casters, and the casters are integrated with a foot-operated locking brake structure.
[0013] It is worth noting that the bottom of the mounting groove is provided with an anti-slip first pad, and the two side walls inside the groove are provided with guide rails with a trapezoidal cross section, and the top of the guide rails is provided with an anti-detachment flange.
[0014] Furthermore, it should be noted that the first inner box and the second inner box are provided with limiting grooves on both side walls. The limiting grooves have a trapezoidal cross section and are embedded with wear-resistant sliders, forming a sliding fit with the guide rail. In addition, a buffer rubber layer is added between the guide rail and the limiting groove.
[0015] Furthermore, it should be noted that the side walls of the first inner box and the second inner box are provided with array-type heat dissipation slots, the bottom of the box is provided with a second bottom pad, and the top is hinged with an inner box cover plate, the surface of which is provided with a handle.
[0016] As a preferred embodiment, the lock body structure is a double-tongue combination lock, integrated into the middle of the edge of the box lid.
[0017] In a preferred embodiment, the first fixing plate and the second fixing plate are connected by a detachable fixing shaft, one end of which is provided with a threaded part and locked by a fixing bolt.
[0018] As a preferred embodiment, the cover of the inner box structure can be replaced with a transparent material to facilitate observation of the internal items.
[0019] Compared with the prior art, the modular and scalable logistics storage device provided by this utility model has at least the following beneficial effects:
[0020] (1) The core advantage of this device lies in its modular design concept. The interior of the outer box is naturally divided into three independent installation slots by specific partitions, and each slot can slide in an independent inner box unit. This structure allows users to flexibly choose to install inner boxes of different specifications in the three compartments according to the type, size, or access frequency of the actual items, achieving refined compartment management. More importantly, the symmetrical expansion connection structure on both sides of the device is a key innovation. Through the snap-fit part on one side of the fixing plate and the matching slot on the other side of the fixing plate, multiple identical storage units can be easily and stably connected laterally. This design breaks through the capacity limitation of a single box, allowing users to splice any number of units as needed, instantly expanding the overall storage space and forming a unified and orderly transportation array. All inner boxes can be pulled out and accessed independently without interfering with each other, while the expanded whole can be moved uniformly by the universal wheels with locking brake structure integrated at the bottom, greatly improving the flexibility, efficiency, and space utilization of logistics warehousing and transportation.
[0021] (2) This device features multiple optimizations and integrations in terms of security, stability, and ease of use. The outer lid integrates a double-tongue combination lock, providing reliable overall anti-theft protection. The inner box itself can also be equipped with a cover with a handle, and a transparent material can be selected for quick viewing of the contents, balancing safety and convenience. In terms of structural stability, the inner box and the mounting slot use a special trapezoidal cross-section guide rail and a limiting groove with wear-resistant sliders and a buffer rubber layer, which not only ensures smooth sliding but also effectively prevents the inner box from accidentally falling off or violently colliding during transportation, providing good cushioning protection for the contents (especially fragile items). Four universal wheels with foot-operated locking brakes at the bottom allow for easy and stable movement of single or expanded large combined units, and can be securely locked in position when needed. The detachable fixed shaft design further simplifies the connection and separation of expansion units. These features together constitute a safe, stable, labor-saving, and user-friendly logistics storage solution. Attached Figure Description

[0027] The present invention will be further described below with reference to the embodiments.
[0028] Please see Figure 1-4 This utility model provides a modular and expandable logistics storage device, comprising: an outer box 1, an expansion unit 3, and an inner box structure 6.
[0029] The outer casing 1 has a T-shaped partition 4 inside, which divides the inner cavity into three independent mounting slots;
[0030] A lid 5 is hinged to one side of the upper end of the outer box 1, and a lock body structure 501 is provided on the edge of the lid 5;
[0031] The expansion unit 3 is symmetrically arranged on the left and right sides of the outer box 1, including a first fixing plate 301 and a second fixing plate 302. The first fixing plate 301 is fixed to the left side wall of the outer box 1, and the second fixing plate 302 is fixed to the right side wall of the outer box 1.
[0032] The inner box structure 6 includes two first inner boxes 601 and one second inner box 602, which are slidably connected in three mounting slots respectively;
[0033] The second fixing plate 302 has a slot 3021 on the side away from the outer box, and the first fixing plate 301 has a snap-fit part that matches the slot 3021 at the end away from the outer box.
[0034] Further as Figure 1 As shown, it is worth noting that the four corners of the bottom of the outer casing 1 are equipped with casters 2. The casters 2 integrate a foot-operated locking brake structure. The casters 2 installed at the four corners of the bottom of the outer casing 1 greatly improve the ease of movement of the device, making it easy to turn and push. The integrated foot-operated locking brake structure can quickly lock the position of the device, preventing it from moving accidentally during loading, unloading or storage, ensuring operational safety and stability.
[0035] Further as Figure 2As shown, it is worth noting that the bottom of the mounting groove is equipped with an anti-slip first pad 101, and the two side walls of the groove are equipped with trapezoidal guide rails 102. The top of the guide rails 102 is equipped with an anti-detachment flange. The anti-slip first pad 101 at the bottom of the mounting groove effectively prevents the inner box from sliding or shifting due to vibration within the groove. The trapezoidal guide rails 102 on the two side walls of the groove and the anti-detachment flange at their tops provide precise guidance for the sliding of the inner box and reliably prevent the inner box from accidentally detaching from the mounting groove during extraction or transportation, thus enhancing the safety of use.
[0036] Further as Figure 3 As shown, it is worth noting that the first inner box 601 and the second inner box 602 have limiting grooves 604 on both side walls. The limiting grooves 604 have a trapezoidal cross-section and are embedded with wear-resistant sliders, forming a sliding fit with the guide rail 102. A buffer rubber layer is added between the guide rail 102 and the limiting grooves 604. The matching shape of the limiting grooves 604 on both side walls of the first inner box 601 and the second inner box 602 with the guide rail 102 ensures smooth and stable sliding. The embedded wear-resistant sliders significantly reduce frictional resistance and improve the durability of the sliding components. The added buffer rubber layer effectively absorbs impacts and vibrations during transportation or operation, protecting the inner boxes and their contents from damage.
[0037] This solution has the following working process: The interior of the outer casing 1 is divided into three independent mounting slots by a T-shaped partition 4. Two first inner casings 601 and one second inner casing 602 are respectively installed into the slots through limiting grooves 604 on both side walls and trapezoidal cross-section guide rails 102 in the mounting slots. The anti-slip first bottom pad 101 at the bottom of the mounting slot and the second bottom pad 607 at the bottom of the inner casing work together to prevent slipping and reduce shock. Users can open the inner casing cover 605 through the handle 606 to access items. The side wall heat dissipation grooves 603 assist in ventilation. When expanding, the snap-fit part of the first fixing plate 301 of the adjacent outer casing unit is aligned with the snap-fit groove 3021 of the second fixing plate 302 of the current unit and snapped in for initial positioning. Then, the detachable fixing shaft 303 is inserted and tightened with the fixing bolt 3031 to lock it, realizing a rigid connection of multiple units. After closing the outer casing cover 5, the double-tongue combination lock body structure 501 on the edge of the cover is operated to lock the entire device. The four casters at the bottom corners 2 facilitate movement of the device, and the integrated foot-operated locking brake structure can be pressed to fix the position. The anti-slip flange at the top of the guide rail 102 and the buffer rubber layer between it and the limiting groove 604 ensure smooth sliding of the inner box, shock absorption, and prevent it from falling out.
[0038] As can be seen from the above working process: the casters 2 installed at the four corners of the bottom of the outer casing 1 greatly improve the ease of movement of the device, making it easy to turn and push. The integrated foot-operated locking brake structure can quickly lock the position of the device, preventing it from moving accidentally during loading, unloading, or storage, ensuring operational safety and stability; the anti-slip first bottom pad 101 at the bottom of the mounting slot effectively prevents the inner casing from sliding or shifting due to vibration within the slot. The trapezoidal cross-section guide rails 102 on both sides of the inner casing and the anti-detachment flange at the top provide precise guidance for the sliding of the inner casing and reliably prevent the inner casing from accidentally falling out of the mounting slot during extraction or transportation, enhancing the safety of use; the trapezoidal cross-section limiting grooves 604 on both sides of the first inner casing 601 and the second inner casing 602 match the shape of the guide rails 102, ensuring smooth and stable sliding. The embedded wear-resistant slider significantly reduces frictional resistance and improves the durability of the sliding parts. The added buffer rubber layer can effectively absorb the impact and vibration during transportation or operation, protecting the inner casing and its contents from damage.
[0039] Further as Figure 3 As shown, it is worth noting that the side walls of the first inner box 601 and the second inner box 602 have arrayed heat dissipation grooves 603, the bottom of the box has a second bottom pad 607, and the top is hinged to an inner box cover 605. The surface of the inner box cover 605 has a handle 606. The arrayed heat dissipation grooves 603 on the side walls of the first inner box 601 and the second inner box 602 promote air circulation inside the box, which helps to dissipate the heat generated by the internal equipment or items and prevent overheating. The second bottom pad 607 at the bottom of the box further enhances the anti-slip and shock absorption effect, protecting the items inside the box. The hinged inner box cover 605 at the top makes it easy to open and access small items, and the handle 606 on its surface greatly facilitates the pushing and pulling operation of the inner box.
[0040] Further as Figure 1 As shown, it is worth noting that the lock body structure 501 is a double-tongue combination lock, integrated into the center of the edge of the cover 5. By employing a double-tongue combination lock in the lock body structure 501 and integrating it into the center of the edge of the cover 5, a high level of overall security against theft is provided. The combination lock requires no key, making operation convenient and avoiding the risk of key loss. The double-tongue structure enhances the lock's stability.
[0041] Further as Figure 4As shown, it is worth noting that the first fixing plate 301 and the second fixing plate 302 are connected by a detachable fixing shaft 303. One end of the fixing shaft 303 has a threaded portion and is locked by a fixing bolt 3031. This design makes the connection between the expansion units 3 both quick (initial positioning through snap-fit) and very secure and reliable (locked by threads). At the same time, the detachability makes the connection and separation of the expansion units simple and quick, improving the flexibility of modular expansion.
[0042] Further as Figure 1 As shown, it is worth noting that the cover 605 of the inner box structure 6 can be replaced with a transparent material, which makes it easier to observe the status of the items inside. By replacing the cover 605 of the inner box structure 6 with a transparent material, users can directly observe the status of the items inside (such as quantity, integrity or specific indicators) without frequently opening the inner box cover 605, which greatly improves the convenience and efficiency of item inspection, and is especially suitable for scenarios that require frequent viewing or monitoring of specific items.
[0043] In summary: The array-type heat dissipation grooves 603 on the side walls of the first inner box 601 and the second inner box 602 promote air circulation inside the box, helping to dissipate heat generated by internal equipment or items and prevent overheating. The second bottom pad 607 at the bottom of the box further enhances the anti-slip and shock absorption effect, protecting the items inside. The hinged top inner box cover 605 facilitates the individual opening and access of small items, and the handle 606 on its surface greatly facilitates the pushing and pulling operation of the inner box; the lock body structure 501 adopts a double-tongue combination lock and is integrated into the middle of the edge of the box cover 5, providing high-security overall anti-theft protection. The combination lock does not require a key, is convenient to operate, and avoids the risk of losing the key. The double-tongue structure enhances the locking firmness; the first fixing plate 301 and the second fixing plate 302 are connected by a detachable fixing shaft 303, one end of which has a threaded part and is locked by a fixing bolt 3031. This design makes the connection between the expansion units 3 both quick (initial positioning through snap-fit) and very firm and reliable (locking through threads). Meanwhile, the detachability makes the connection and separation of the expansion unit simple and quick, improving the flexibility of modular expansion; the cover 605 of the inner box structure 6 can be replaced with a transparent material, so that users can directly observe the status of the internal items (such as quantity, integrity or specific indicators) without frequently opening the inner box cover 605, which greatly improves the convenience and efficiency of item inspection, especially suitable for scenarios that require frequent viewing or monitoring of specific items.
