Description

Technical Field

[0001] This utility model relates to the field of construction site technology, and more specifically, to a portable multi-functional toolbox for construction sites. Background Technology

[0002] A construction site, also known as a building site or construction site, is a location where a construction project is underway and civil engineering is being carried out. The site is often enclosed by fences, wire mesh, or walls to restrict the entry and exit of personnel, materials, machinery, and vehicles. During the construction process, workers need to use portable toolboxes.

[0003] For example, patent number CN211682025U discloses a construction site toolbox, including a box body. Telescopic devices are fixedly connected to the four corners of the lower end of the box body. A locking ring is fixedly connected to the front end of the box body. A handle is movably connected to the left and right ends of the box body. Two hinges are fixedly connected to the rear part of the upper end of the box body. A box lid is movably connected to the upper end of the box body through the two hinges. A latch is movably connected to the front end of the box lid. A first partition is fixedly connected between the front and rear boxes of the box body. A second partition is fixedly connected between the right box wall of the box body and the right end of the first partition.

[0004] For example, patent number CN212193084U discloses a toolbox for construction, including a box body. The lower side of the box body is provided with feet, and the upper left and right sides of the box body are provided with shoulder straps for carrying the toolbox. The middle of the rear side of the box body is provided with an arc-shaped rubber pad, which is bent inward into the box body. The rear side of the rubber pad is provided with anti-slip texture, which increases friction while being breathable. The upper side of the inside of the box body is provided with guide grooves, and two sliding covers are slidably connected in the guide grooves.

[0005] However, in actual use, most traditional portable toolboxes used on construction sites only have storage functions. Improvements are mostly made to the storage function, without the addition of adjustable auxiliary lighting. This makes it impossible to use the toolbox properly in dim or dark environments, and it cannot provide adequate lighting for the user when needed. It also cannot serve as a temporary light warning structure when needed, greatly reducing the functionality of the toolbox. Furthermore, the lack of auxiliary expansion storage structures means that it cannot provide temporary storage space for frequently used tools, making it easy for tools to be lost. It also cannot be used as a temporary workbench, and therefore cannot serve as a support surface for simple drawing, recording, or equipment debugging. Consequently, it cannot adapt to the changing needs of construction sites, further reducing the functionality of the toolbox. Utility Model Content

[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides a portable multi-functional toolbox for construction sites. This addresses the problem that existing technologies lack adjustable auxiliary lighting structures, making the toolbox unusable in dim or dark environments. Furthermore, the toolbox cannot provide adequate illumination or serve as a temporary warning light when needed, significantly reducing its functionality. Additionally, the lack of an auxiliary expansion storage structure prevents users from having access to frequently used tools, increasing the risk of tool loss. Moreover, the toolbox cannot be used as a temporary workbench or a support surface for simple drawing, recording, or equipment debugging, thus failing to meet the diverse needs of construction sites and further reducing its functionality.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable multi-functional toolbox for construction sites, including a box body, a box cover hinged to the top of the back of the box body via a first hinge, vertical plates rotatably mounted on both sides of the box body, and a lifting column rotatably mounted on the top of the vertical plates that are close to each other via a horizontal axis, an adjustable auxiliary lighting component provided on the lifting column and the vertical plates, and an auxiliary expansion placement component provided on the box cover.

[0008] The adjustable auxiliary lighting assembly includes symmetrically fixed isolation sleeves on the lifting column. Each lifting column has placement slots on both sides of its bottom, and each placement slot contains an LED light. Protective sleeves are rotatably mounted on both sides of the lifting column, with both ends of each protective sleeve fitting against the isolation sleeve and the vertical plate on their respective sides. One set of vertical plates has a drive motor with an output shaft fixed to one set of horizontal shafts via a mounting sleeve. Each set of protective sleeves has an auxiliary groove at its bottom adapted to the LED light. A sliding frame with its bottom slidably disposed within the isolation sleeve is fixed to the inner side of the bottom of each set of protective sleeves. A locking bracket is slidably disposed within the sliding frame. Each set of isolation sleeves has fixed slots at its top and bottom, with the bottom end of the locking bracket inserted into the lower fixed slot. A first spring is fixed between the locking bracket and the inner cavity of the sliding frame.

[0009] The auxiliary expansion placement assembly includes an expansion side plate hinged to the front of the box lid via a second hinge. A limiting bracket is inserted into the front of the expansion side plate. The front of the box lid has limiting square holes for the two ends of the limiting bracket to be inserted. Multiple sets of strip grooves are formed on the front of each expansion side plate. A second spring with one end fixed to the limiting bracket is fixed in each set of strip grooves. Support side plates are rotatably mounted on the front of both sides of the expansion side plate. Anti-slip brackets are fixed on both sides of the limiting bracket. Anti-slip holes are formed on the top of the support side plates for the anti-slip brackets to be inserted. Screw holes are formed at the bottom of each set of support side plates. A connecting screw rod with a base fixed at the bottom end is threaded into the screw hole.

[0010] An auxiliary magnetic plate is embedded on the front of the top of the extended side panel, and a fixed magnetic plate that attracts the auxiliary magnetic plate is fixed on the back of the top of the box cover.

[0011] The bottom of the front of the box cover is symmetrically fixed with load-bearing plates that are attached to the bottom of the extended side plate. The top of the back of both sides of the extended side plate is fixed with a blocking top plate that works in conjunction with the connecting screw.

[0012] One set of vertical plates has a limit bolt at its bottom, and the side of one set of vertical plates that is close to the box body is threadedly connected to the limit bolt through an auxiliary threaded hole.

[0013] The bottom of the back of the box is fixed with a side box, and a small mobile power supply for use with the drive motor is fixed inside the side box. A socket for use with the small mobile power supply is embedded on the side of the side box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by setting an adjustable auxiliary lighting component, a certain amount of light can be provided to the user in some dim or dark environments, so that the user can use the toolbox normally. The angle of the light can be freely adjusted, and the LED light can be driven to rotate continuously, so as to temporarily serve as a light warning structure when needed, which improves the functionality of the toolbox. It can also form a protective structure for the LED light, so as to shield and protect the LED light when it is not in use, so as to avoid damage. At the same time, the design of the auxiliary expansion storage component, using an expansion side plate with a locking structure, together with the adjustable support structure on both sides, can form a temporary storage surface while ensuring the stability of the expansion side plate, so as to provide the user with temporary storage space. It is convenient to temporarily collect and store frequently used tools taken out of the toolbox, so as to prevent tools from being easily lost. It can also be used as a temporary workbench, which is convenient for simple drawing, recording or equipment debugging, adapting to the changing needs of the construction site, further improving the functionality of the toolbox.

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0027] Please see Figures 1 to 8 This utility model provides an embodiment: a portable multi-functional toolbox for construction sites, including a box body 1. A controller is embedded in the bottom of one side of the box body 1. A box cover 2 is hinged to the top of the back of the box body 1 via a first hinge. Vertical plates 3 are rotatably mounted on both sides of the box body 1. Lifting columns 4 are rotatably mounted on the top of the vertical plates 3 that are close to each other via a horizontal axis. The lifting columns 4 and the vertical plates 3 can form an auxiliary lifting structure to facilitate carrying the toolbox. A limit bolt 18 is provided at the bottom of one set of vertical plates 3. The side of one set of vertical plates 3 that is close to the box body 1 is threadedly connected to the limit bolt 18 through an auxiliary threaded hole. The position of the vertical plates 3 can be limited by the threaded connection between the limit bolt 18 and the auxiliary threaded hole. To ensure it remains vertical when needed for convenient lighting, adjustable auxiliary lighting components are installed on the lifting column 4 and the vertical plate 3. These components provide illumination for construction workers and can also serve as temporary warning lights, enhancing the toolbox's functionality. An auxiliary expansion storage component is also provided on the lid 2. This component allows for temporary storage of frequently used tools, preventing loss, and can also function as a temporary workbench for simple drawing, recording, or equipment debugging, adapting to changing site conditions and further improving the toolbox's functionality.

[0028] Please see Figures 1 to 4 , Figure 7 and Figure 8In this embodiment, the adjustable auxiliary lighting assembly includes symmetrically fixed isolation sleeves 19 on the lifting column 4. Placement slots 21 are provided on both sides of the bottom of the lifting column 4, and an LED lighting lamp 22 is fixed in each placement slot 21. Protective sleeves 20 are rotatably mounted on both sides of the lifting column 4. The two ends of each protective sleeve 20 are attached to the side where the isolation sleeves 19 and the vertical plate 3 are close to each other. A drive motor 31 with an output shaft fixed to one of the horizontal shafts is fixed on one of the vertical plates 3 via a mounting sleeve. A side box 29 is fixed to the bottom of the back of the housing 1. The toolbox 29 contains a small portable power supply 30 for use with the drive motor 31. The small portable power supply 30 provides a power source for the drive motor 31. The LED light 22 is rechargeable. A socket for use with the small portable power supply 30 is embedded on the side of the side box 29. The socket is designed to serve as a temporary connection point, providing temporary power to external devices, further enhancing the toolbox's functionality. Each set of protective sleeves 20 has an auxiliary groove 23 at its bottom for use with the LED light 22. Each set of protective sleeves 20 has a sliding frame 24 fixed to the inner side of its bottom, which is slidably disposed within the isolation sleeve 19. A locking bracket 26 is slidably disposed within the sliding frame 24. Each set of isolation sleeves 19 has a fixed groove 27 at its top and bottom, with the bottom end of the locking bracket 26 inserted into the lower fixed groove 27. A first spring 25 is fixed between the locking bracket 26 and the inner cavity of the sliding frame 24. The adjustable auxiliary lighting assembly, utilizing multiple sets of LED lights 22, can provide users with appropriate illumination in dim or dark environments, allowing users to... The toolbox is in normal use, and the design of the drive motor 31 can drive the LED light 22 to rotate. It can also be fixed in a vertical position as a vertical plate 3, so as to temporarily serve as a light warning structure when needed, which improves the functionality of the toolbox. The design of the isolation sleeve 19, locking bracket 26, sliding frame 24, first spring 25 and protective sleeve 20 can form a protective structure for the LED light 22, so that the LED light 22 can be shielded and protected when it is not in use, so as to prevent the LED light 22 from being easily damaged, which further improves the functionality.

[0029] Please see Figure 1 , Figure 2 , Figure 4 and Figures 6 to 8In this embodiment, the auxiliary expansion placement assembly includes an expansion side plate 5 hinged to the front of the lid 2 via a second hinge. An auxiliary magnetic plate 16 is embedded on the front top of the expansion side plate 5, and a fixed magnetic plate 17 is fixed on the back top of the lid 2, which attracts the auxiliary magnetic plate 16. The mutual attraction between the auxiliary magnetic plate 16 and the fixed magnetic plate 17 allows the expansion side plate 5 to be positioned when reset, and can also temporarily hold small tools such as screwdrivers, preventing them from being easily lost, thus further improving the functionality of the toolbox. A limiting bracket 6 is inserted into the front of the expansion side plate 5, and a limiting bracket is provided on the front of the lid 2. The back of the frame 6 has two end holes 9 for inserting positioning. The front of the extension side plate 5 has multiple sets of strip grooves 7, each containing a second spring 8 fixed at one end to the positioning frame 6. Supporting side plates 10 are rotatably mounted on the front of both sides of the extension side plate 5. Anti-slip frames 11 are fixed on both sides of the positioning frame 6. Anti-slip holes 12 for inserting the anti-slip frames 11 are provided on the top of the supporting side plates 10. Screw holes 14 are provided at the bottom of each supporting side plate 10, with threaded connections to connecting screw rods 13 whose bottom ends are fixed to the base. Symmetrically fixed to the bottom of the front of the cover 2 are top-mounted fittings that conform to the extension plate. The load-bearing plate 28 at the bottom of the extended side panel 5 and the top of the back sides of both sides of the extended side panel 5 are fixed with blocking top plates 15 that cooperate with the docking screw 13. The design of the load-bearing plate 28 not only limits the flipping position of the extended side panel 5, but also provides auxiliary support for the extended side panel 5, improving the stability of the extended side panel 5. At the same time, the design of the blocking top plate 15 helps to position the docking screw 13, avoids excessive upward swing and reset, and assists in the design of the extended placement component. The design of the limiting frame 6, the second spring 8, and the limiting square hole 9 can form a locking structure for the extended side panel 5, so as to quickly open the extended side panel 5 after unfolding. The design of the fixed anti-slip bracket 11 and anti-slip hole 12, together with the support side plate 10, screw hole 14 and connecting screw 13, can form an adjustable support structure for the extension side plate 5 to ensure the stability of the extension side plate 5. At this time, the extension side plate 5 can provide users with a certain temporary storage space as needed, and tools that need to be taken out of the toolbox and used frequently can be temporarily placed in a centralized manner to avoid tools being easily lost. It can also be used as a temporary workbench, which is convenient as a support surface for simple drawing, recording or equipment debugging, adapting to the changing needs of the construction site, and further improving the functionality of the toolbox.

[0030] The working process of this utility model is as follows:

[0031] When working in dimly lit or dark environments, the user first removes the necessary tools from the housing 1 and swings the vertical plate 3 to a vertical position. Then, the user rotates the limiting bolt 18 to connect it to the auxiliary threaded hole on the side of the housing 1, fixing the vertical plate 3. Next, the user moves the locking bracket 26 until it disengages from the top slot 27, releasing the locking of the sliding frame 24 and the protective sleeve 20, and simultaneously compressing the first spring 25. The user then rotates the protective sleeve 20 until the auxiliary groove 23 is rotated downwards, and the LED... With the LED lights 22 exposed, the elastic rebound of the first spring 25 drives the locking bracket 26 to move and insert into the lower slot 27. The user can then activate multiple LED lights 22 via the controller, providing illumination in dim or dark environments. Simultaneously, the user can activate the drive motor 31, which rotates the lifting column 4, adjusting the beam angle of the LED lights 22 and continuously driving them to serve as temporary lighting when needed. The warning structure enhances the toolbox's functionality. When the user pulls the limiting bracket 6 to a certain distance, the second spring 8 is stretched, and simultaneously the anti-slip bracket 11 disengages from the supporting side plate 10. The user then flips the extended side plate 5 from the lid 2 to the front, where it contacts the load-bearing plate 28. At this point, the supporting side plate 10 swings down to a vertical position. Simultaneously, the elastic rebound of the second spring 8 pushes the limiting bracket 6 into the limiting square hole 9, and the anti-slip bracket 11 into the anti-slip hole 12, limiting the extended side plate 5 and the supporting side plate 10. The user then rotates the... Connect the lead screw 13 to rotate and move it within the screw hole 14 until the bottom base contacts the ground. At this time, the support side plate 10 can provide stable support for the extension side plate 5. Under the premise of ensuring the stability of the extension side plate 5, the extension side plate 5 can provide users with a certain temporary storage space as needed. Tools that need to be taken out of the toolbox and used frequently can be temporarily placed in a centralized manner to avoid tools being easily lost. It can also be used as a temporary workbench, and is convenient as a support surface for simple drawing, recording or equipment debugging, adapting to the changing needs of the construction site and further improving the functionality of the toolbox.

[0032] Compared to the comparison documents and common existing technologies that only improve the storage function of the toolbox, the toolbox's functionality remains very limited, merely serving as storage. In dimly lit or dark environments, the toolbox cannot function properly and cannot provide adequate lighting, requiring users to find alternative light sources, which significantly delays work progress. Furthermore, it requires additional wiring from the electrical box, which is cumbersome and poses certain safety hazards. The lack of auxiliary expansion storage structures prevents the creation of a temporary storage surface, directly hindering the user's ability to temporarily store frequently used tools, increasing the risk of tool loss. It also cannot be used as a temporary workbench or as support for simple drawing, recording, or equipment debugging. The existing toolboxes are unsuitable for the changing needs of construction sites. This application, however, uses adjustable auxiliary lighting components and auxiliary extension placement components, which can provide users with adequate illumination in dim or dark environments. The lighting angle is freely adjustable, offering greater adaptability and better performance. It can also temporarily function as a warning light structure, diversifying the toolbox's functions. Furthermore, it forms a temporary placement surface, facilitating the centralized storage of frequently used tools to prevent loss. It can also be used as a temporary workbench, providing support for simple drawing, recording, or equipment debugging. Compared to the prior art, this application offers greater functionality, adapts to the changing needs of construction sites, provides better performance, and utilizes readily available and inexpensive components.

[0033] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0034] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
