[0026] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0027] like Figure 1 As shown, the portable construction engineering design box of the present application is intended to provide a portable, safe and easy-to-manage design tool box. The design box is mainly used to accommodate and protect various construction engineering drawings and tools, ensuring that they are not easily damaged during transportation and storage.

[0028] refer to Figure 2The design box includes a main body, namely the box body 1. The box body 1 is a shell structure made of high-quality, durable materials, and has sufficient strength to protect the valuable drawings and tools inside. The box body 1 is equipped with multiple functional components, one of the most important components is the movable partition 2. The movable partition 2 is installed inside the box body 1 and can be moved and adjusted as needed. By changing the position of the movable partition 2, the user can freely adjust the size of the storage area to accommodate storage items of different types and sizes. This makes the design box more flexible when accommodating various architectural drawings and tools of different sizes.

[0029] Another key component is the folding support frame 3, which is located on both sides of the bottom surface of the box 1. The support frame is designed to be foldable. When the box 1 is closed, the support frame completely folds and stores inside the box 1, saving space. When the box 1 is opened, the support frame can be unfolded to form a stable platform for users to unfold and view drawings. The support frame design not only provides stable support but also prevents contamination or damage caused by placing drawings directly on the ground.

[0030] For easy portability, a retractable handle 4 is fixed to the center of the top exterior of the case 1. Made of sturdy material, the handle 4 can be locked at different lengths using a knob to accommodate different heights and carrying requirements. This design ensures comfort and convenience when carrying the case, especially during extended trips or stair climbing.

[0031] To ensure the safety of the box, locking devices 5 are installed on both sides of the front edge of the box body 1. These locking devices 5 securely close the lid and bottom of the box body 1 through a secure snap-fit ​​mechanism, preventing the contents from accidentally slipping out in the event of an external impact. The locking devices 5 also provide an anti-theft feature, allowing for the installation of a small lock to further enhance security.

[0032] Among them, the box body 1 is made of high-strength composite material, and the surface is scratch-resistant to increase the service life. The movable partition 2 is fixed to the inside of the box body 1 by a slide rail system, and the slide rail allows the partition to move and position smoothly. There are fixing holes at both ends of the slide rail, and the user can fix the partition in the desired position by rotating the fixings. The folding support frame 3 is made of high-strength steel and is connected by a pivot in the middle to ensure stability and reliability during folding and unfolding. The telescopic handle 4 is equipped with a multi-section locking mechanism, and the extension length of the handle can be controlled by a knob to adapt to different usage scenarios. The locking device 5 uses an elastic retaining spring design to achieve locking and unlocking through manual operation.

[0033] The movable partition 2 of this design allows users to freely adjust the space layout inside the box 1 according to actual conditions, effectively avoiding cross-contamination and damage between different types of items. The foldable support frame 3 provides a stable placement platform for drawings, making it more convenient and safer during use.

[0034] In one embodiment, a portable construction engineering design box of the present application has the following features: the box body 1 is provided with a plurality of fixed slots 6, into which movable partitions 2 are inserted for stable installation. The movable partitions 2 can slide up and down within the fixed slots 6 to achieve more flexible space adjustment. This design effectively prevents different types of engineering drawings and tools from being mixed together, ensuring that each item has its own independent space. The internal space layout of the box body 1 can be quickly adjusted according to actual needs, improving the convenience of storing and accessing various tools and drawings.

[0035] Specifically, fixed slots 6 are arranged vertically on both sides of the interior of the box 1. Each slot has a specific depth and width to securely accept the movable partitions 2. The spacing between these slots is well-designed to accommodate partitions of varying heights and thicknesses, allowing the internal space of the box 1 to be flexibly adjusted to meet user needs. For example, users can designate different areas within the box 1 for storing large and small drawings, or tools of various sizes.

[0036] For example, the movable partition 2 is typically made of a high-strength material, providing sufficient rigidity and stability. To ensure the secure fit and smooth sliding of the movable partition 2 within the fixed slot 6, appropriate tolerances are required between the slot and the partition. The interior of the fixed slot 6 may be equipped with anti-slip rubber pads or grooves to increase friction and prevent the partition from slipping out due to shaking. Furthermore, the partition may also have guide strips along its edges to ensure smooth movement within the slot while maintaining stability.

[0037] In one embodiment, the movable partition 2 of the portable construction engineering design box of the present application includes a plurality of foldable partition units 7 (refer to Figure 2 ). The design of these partition units allows them to adjust their folding state according to actual needs, thereby forming storage compartments with various functions. Each partition unit is connected together by a hinge shaft 8. This hinge method enables the partition units to be folded or unfolded with each other, improving the space utilization inside the design box and effectively avoiding the mixing of tools and drawings. The movable partition 2 is usually located in the middle area inside the design box and can be detachably connected to the box body 1 by a slide rail or other fixing device, so that the user can flexibly adjust the state of the partition according to different usage scenarios.

[0038] In one embodiment, these partition units are typically made of lightweight materials to ensure portability. Specifically, the connection portion of the partition units is provided with a hinge shaft 8, which allows each partition unit to rotate freely along the hinge shaft 8, thereby achieving the function of folding and unfolding. In addition, in order to ensure the stability and reliability of the movable partition 2 during use, a locking device may be provided between each partition unit to ensure that it remains fixed in the unfolded state and prevent accidental folding that may cause confusion of the internal items. For example, a snap-fit ​​structure can be provided on one side of each partition unit so that they lock together in the unfolded state to ensure that they will not move arbitrarily due to external interference during use.

[0039] Furthermore, the portable architectural design box, which is the subject of the patent application, is equipped with multiple hooks 21 on its movable partition 2. These hooks 21 are used to hang small items such as tools, allowing tools and drawings to be stored separately, improving storage efficiency and convenience. The design of the movable partition 2 allows users to flexibly adjust the internal space according to actual needs, further enhancing the suitability and flexibility of the design box. Furthermore, the position and number of hooks 21 can be customized to meet the specific needs of the user, ensuring that the design box can meet the needs of different usage scenarios.

[0040] The movable shelf 2 is removably secured to the interior of the design box, allowing users to adjust its position at will based on the number and type of items stored. For example, hooks 21 are evenly distributed on one or both sides of the shelf 2, allowing users to conveniently hang various small tools and accessories without hindering access to larger items such as blueprints. Each hook 21 is made of high-strength metal to ensure its strength and durability.

[0041] Specifically, the hooks 21 of the movable partition 2 can be secured to the partition by welding or threading to ensure a secure and reliable connection. For example, in one embodiment, the base of the hook 21 is a metal block with a threaded hole, which is secured to a designated position on the movable partition 2 via bolts. This connection method not only facilitates installation and removal, but also allows the number and position of the hooks 21 to be adjusted as needed to accommodate different usage requirements.

[0042] In addition, in one embodiment, the movable partition 2 of the portable architectural engineering design box of the present application is covered with a layer of anti-slip material 24. This anti-slip material layer 24 effectively prevents the drawings from sliding when placed, ensuring the stability and safety of the drawings during transportation and use. The anti-slip material layer 24 also has certain moisture-proof properties, which can extend the service life of the engineering drawings and ensure storage quality. Specifically, the anti-slip material layer 24 is a specially treated material, such as soft polyurethane or rubber material, which not only provides sufficient friction to prevent sliding but also effectively resists moisture penetration.

[0043] In order to meet the needs of the scenario, the design of the movable partition 2 adopts a compression molding method, and the anti-slip material layer 24 is directly attached to the surface of the movable partition 2 during the molding process. This manufacturing process not only ensures the flatness of the anti-slip material layer 24, but also ensures its close bonding with the movable partition 2, avoiding the problem of falling off or separation during long-term use. In addition, in order to further improve the moisture-proof performance, a layer of waterproof and breathable membrane can be added under the anti-slip material layer 24. This membrane material can block external moisture while allowing internal moisture to escape slowly, thereby achieving a two-way protection effect. For example, the waterproof and breathable membrane can be fixed to the bottom layer of the movable partition 2 through a high-temperature bonding process to ensure the stability and functionality of the overall structure.

[0044] refer to Figure 2 and Figure 3 In one embodiment, the folding support frame 3 of a portable construction engineering design box of the present application includes a pair of telescopic support rods 11 and a connecting rod 12. The telescopic support rods 11 and the connecting rod 12 are connected by a damping shaft 13. The damping shaft 13 has a self-locking property, thereby ensuring the stability and reliability of the support frame. Specifically, one end of the pair of telescopic support rods 11 is connected to the two sides of the outside of the box body 1, and the other end is connected to the connecting rod 12 through the damping shaft 13, so that the telescopic support rods 11 can be telescopically adjusted and locked at the desired length position. The connecting rod 12 is fixed in a fixing groove 14 on the bottom surface of the box body 1 to ensure that the drawings can be stably supported after the support frame is unfolded to prevent the drawings from slipping or deformation.

[0045] Specifically, the telescopic support rod 11 is constructed from nested, multi-section steel pipes. Each section can be extended or retracted relative to the previous section and locked in place by a built-in spring or locking mechanism. The connecting rod 12 is a solid or hollow metal rod with slots or set screws at each end for secure connection to the fixing slot 14. The damping shaft 13 consists of a bearing filled with oil or other viscous medium. While providing rotational resistance, its internal mechanical structure achieves an automatic locking function, ensuring a stable support state after the support angle is adjusted.

[0046] In one embodiment, see Figure 4The telescopic handle 4 of a portable construction engineering design box of the present application includes a fixed part 15 and a movable part 16. The fixed part 15 is installed on the top outside of the box body 1 to provide guidance and support for the movable part 16. The movable part 16 can slide up and down along the fixed part 15 so that the user can adjust the height of the handle as needed. In addition, a positioning button 9 is provided on the movable part 16. When the movable part 16 moves to the required height, the positioning button 9 can cooperate with the positioning hole 10 on the fixed part 15 to lock the position of the movable part 16. Multiple groups of positioning holes 10 are opened on one side wall of the fixed part 15 to adapt to different height requirements.

[0047] Specifically, the positioning button 9 of the movable portion 16 is typically connected internally via a spring or spring structure. When pressed, the button retracts inward, releasing the locking mechanism from the positioning hole 10. When released, the button springs out and reinserts into the corresponding positioning hole 10. This design not only enhances the height adjustment flexibility of the handle but also enhances comfort and safety during use. For example, the fixed portion 15 can be made of a high-strength metal material to ensure it can withstand heavy weight, while the movable portion 16 can be made of a lightweight but wear-resistant material to facilitate sliding operation.

[0048] In one embodiment, the locking device 5 of a portable construction engineering design box of the present application mainly consists of two parts: a fixing seat 17 and an elastic buckle 18 (refer to Figure 1 Mounting bracket 17 is mounted on the front edge of case 1, positioned to tightly integrate with the main structure of case 1, providing a stable mounting point. An elastic buckle 18 is secured via a pin 19 to the other side of the front end of case 1, corresponding to the side where mounting bracket 17 is located. This ensures that elastic buckle 18 covers and locks mounting bracket 17. Elastic buckle 18 possesses a certain degree of elasticity and rigidity, allowing it to securely engage mounting bracket 17, thereby locking case 1.

[0049] For example, fixing base 17 can be a solid metal block or plastic part, and its installation position must be precisely measured to ensure perfect alignment with the front edge of box body 1. Fixing base 17 is securely fixed to the predetermined position of box body 1 by screws or other fixing means. Elastic buckle 18 can be a curved metal strip or an annular structure made of polymer material, one end of which is fixed to the other side of the front end of box body 1 by pin 19. This allows elastic buckle 18 to open outward in a free state, but to fit tightly against fixing base 17 when subjected to force, ensuring the safety and stability of box body 1 when closed.

[0050] In one embodiment, a portable construction engineering design box of the present application is characterized in that: the box body 1 is provided with anti-slip pads 20 (see Figure 2These anti-slip pads 20 are placed on various areas of the bottom surface of the box 1 to enhance the stability of the drawings and tools. Their special material and surface texture increase friction between the drawings and tools, effectively preventing slippage or collisions caused by shaking during movement. This not only improves storage efficiency but also ensures the reliability of the design box in various environments.

[0051] For example, the anti-slip pads 20 are made of highly elastic anti-slip materials, such as silicone or soft PVC materials, which have excellent anti-slip properties. The anti-slip pads 20 are fixed to different areas of the bottom surface of the box 1 by bonding or snapping to ensure that they are firm and reliable. The size and position of each anti-slip pad 20 are designed according to the size of commonly used drawings and tools to ensure that the drawings and tools can be well supported when they are laid flat or placed upright. For example, a larger anti-slip pad 20 can be provided in the center of the bottom surface of the box 1 for placing large drawings; while several small anti-slip pads 20 are provided around the periphery for fixing small tools and accessories. Through this reasonable layout and material selection, the effect of optimizing storage is achieved.

[0052] In addition, a portable construction engineering design box of the present application is provided with a multifunctional tool bag 22 on the outside of the box body 1 (refer to Figure 1 The multifunctional tool bag 22 includes multiple detachable pockets 23, each of which can be removed and used individually. This allows users to conveniently carry various small tools by category, improving storage and accessibility. The multifunctional tool bag 22 allows users to flexibly adjust their tool carrying method according to their needs in different work environments, thereby improving work efficiency.

[0053] The multifunctional tool bag 22 is secured to the exterior of the case 1 via a secure connection mechanism. This connection mechanism can utilize common methods such as hook and loop, Velcro, or buckles, ensuring that the tool bag 22 is both easily accessible and secure. Each small pocket 23 is connected to the multifunctional tool bag 22 via similarly removable connectors, allowing the user to easily add or remove specific pockets 23 as needed. The number and size of the small pockets 23 can be customized to meet the storage requirements of different tools.

[0054] For example, each small pocket 23 is designed with an opening and equipped with a zipper or snap fastener closure to prevent tools from being lost during carrying. Furthermore, the interior and exterior surfaces of the multifunctional tool bag 22 can be made of waterproof material to further enhance its protective properties. This structure not only ensures the applicability of the multifunctional tool bag 22 in various environments, but also facilitates daily maintenance and cleaning by the user.

[0055] In actual operation, when using this device, the user first unlocks the locking mechanism 5 to easily access the storage space within the case 1. Next, the user can adjust the position of the movable partitions 2, creating storage areas of varying sizes and types by changing their insertion locations. For example, the larger storage space can be used to store larger engineering drawings, while the smaller space can be used to organize and organize engineering tools and accessories of various sizes, achieving efficient and organized storage. When drawing or reviewing drawings, the user flips the case 1 open and deploys the foldable support frames 3 located on both sides of the bottom of the case 1. When deployed, the foldable support frames 3 not only provide stable support for the case 1 but also form a level work surface, allowing drawings to be placed flat on it for easy review, modification, or signature. Throughout the entire process, the retractable handles 4 play a vital role. Whether moving or transporting this portable architectural design case, the user can lift or adjust the length of the retractable handles 4 to meet the needs of different usage scenarios, such as carrying it over short distances or using the extended handles to tow it in public places, greatly enhancing portability and flexibility. The coordination between various components not only ensures the safe and stable performance of the device, but also improves the user experience.
