Description

Technical Field

[0001] This utility model relates to the field of construction electrical equipment management technology, specifically a centralized power supply and management device for electric tools used on construction sites. Background Technology

[0002] Currently, power tools are widely used in various processing, installation, and dismantling operations on construction sites. These tools typically rely on external power supplies. Due to the large number of tools and their high frequency of use, extension cables or split sockets are commonly used for power connections on-site. This results in a large number of charging cables of varying lengths, easily leading to problems such as cable tangling, messy stacking, and disorderly laying. This situation not only affects the efficient use of power tools by workers but also brings significant challenges to on-site management. Especially in confined spaces and densely populated construction environments, tangled cables can easily cause safety hazards such as accidental pulling and tripping.

[0003] To address this issue, some construction companies have attempted to use toolboxes or storage baskets in conjunction with manual cable organization, or employ simple cable hooks and clips for auxiliary management. However, these traditional management methods have significant limitations: firstly, the storage structure is separate from the power supply system, making unified integrated management impossible; secondly, the lack of a dynamic limiting mechanism means that cables are prone to loosening, springing back, or slipping after installation, affecting storage stability. Furthermore, conventional organization methods often rely on manual winding or repeated clipping, resulting in low operational efficiency and high labor intensity, making them unsuitable for the high-frequency, high-intensity work rhythm of construction sites. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a centralized power supply and management device for electric tools on construction sites, aiming to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A centralized power supply and management device for power tools at a construction site includes a base plate, with a support plate connected to one side of the base plate surface, and several power sockets provided on the side of the support plate. Several charging cable placement plates are detachably connected to the surface of the base plate.

[0007] A bearing is installed on one side of the surface of the charging cable placement plate, and a rotating rod is rotatably connected inside the bearing. A rotating panel is sleeved on the outside of the rotating rod. A through hole is opened on the surface of the rotating panel. Several positioning springs are installed on the surface of the rotating panel, and one end of the several positioning springs is connected to the positioning panel. A pull rod is connected to the surface of the positioning panel.

[0008] Furthermore, the pull rod is disposed through the inside of the through hole.

[0009] Furthermore, the surface of the positioning panel is provided with a number of anti-slip protrusions, and the anti-slip protrusions are made of rubber.

[0010] Furthermore, an anti-slip sleeve is fitted onto the middle area of ​​the outer side of the pull rod.

[0011] Furthermore, the surface of the charging cable placement plate is provided with several grooves.

[0012] Furthermore, the surface of the base plate is provided with a plurality of threaded holes, and the surface of the charging cable placement plate is provided with threaded posts, which are engaged with the inside of the threaded holes.

[0013] The present invention provides a centralized power supply and management device for electric tools on construction sites, which has the following beneficial effects:

[0014] This device, with its charging cable placement plate and rotating limiting structure, effectively solves the problem of long, scattered charging cables on construction sites. It centrally organizes and secures excess cables, improving the cleanliness and safety of on-site operations. Especially in complex construction environments with frequent personnel movement, this structure effectively prevents cables from becoming tangled, tripping, or being accidentally pulled, thus improving the stability and reliability of power tools during use.

[0015] The device is easy to operate; users can open and close the limiting components by rotating the panel and pulling the rod, achieving quick storage and release of charging cables without the need for external tools.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] like Figures 1-2 As shown in the figure, the present invention provides a centralized power supply and management device for electric tools at construction sites, including a base plate 1, and a support plate 2 connected to one side of the surface of the base plate 1, and a connecting top plate 3 provided on the top of the support plate 2.

[0022] Several power sockets 4 are provided on the side of the support plate 2, and several charging cable placement plates 6 are detachably connected to the surface of the base plate 1.

[0023] A bearing 11 is mounted on one side of the surface of the charging cable placement plate 6, and a rotating rod 10 is rotatably connected inside the bearing 11. A rotating panel 9 is sleeved on the outside of the rotating rod 10. A through hole 13 is opened on the surface of the rotating panel 9. Several positioning springs 14 are mounted on the surface of the rotating panel 9, and one end of the several positioning springs 14 is connected to a positioning panel 15. A pull rod 12 is connected to the surface of the positioning panel 15. The pull rod 12 is inserted through the through hole 13.

[0024] In one embodiment of this utility model, the device forms a limiting structure that facilitates the management of charging cables by setting components such as a rotating rod 10, a rotating panel 9, a positioning spring 14, a positioning panel 15, and a pull rod 12. This structure can stably press and orderly store excess wires during use.

[0025] The specific work process is as follows:

[0026] When the user needs to store the charging cable, they first rotate the rotating rod 10, which is set inside the bearing 11, causing the rotating panel 9, which is sleeved on the outside of it, to rotate axially. The rotation of the rotating panel 9 brings the pull rod 12 and the positioning panel 15 connected to its surface away from the top of the charging cable placement plate 6, thereby making room for the charging cable.

[0027] Subsequently, the user neatly stacks any excess or overly long portions of the charging cable connected to the power tool on the surface of the charging cable placement plate 6, arranging them into a regular coil or serpentine pattern along a fixed direction. After arrangement, the user pulls the lever 12 upwards, causing the lever 12 to move the positioning panel 15 upwards against the elastic force of the positioning spring 14, while simultaneously compressing the positioning spring 14, thus creating an elastic pre-compression state between the positioning panel 15 and the rotating panel 9.

[0028] Afterwards, the user rotates the rotating panel 9 again, so that it, together with the upward-moved positioning panel 15, rotates back to the top of the charging cable placement plate 6 and aligns with the original position. After releasing the pull rod 12, the positioning spring 14 resets, thereby pressing the positioning panel 15 downward to press and hold the charging cable, thus effectively limiting and fixing the wire placed on the charging cable placement plate 6.

[0029] The above structural design has the following beneficial effects:

[0030] First, the structure utilizes the cooperation between the rotating rod 10 and the bearing 11 to drive the rotating panel 9 to rotate, thereby causing the pull rod 12 and the positioning panel 15 to deflect as a whole. This facilitates the quick opening of the limiting component before charging, providing a neat working space for storing the charging cable. Users can neatly stack excess wires on the charging cable placement plate 6 without tangling or knotting, effectively avoiding the safety hazards caused by scattered or tangled wires.

[0031] Secondly, when the pull rod 12 is lifted, the positioning spring 14 is compressed. Then, the rotating panel 9 is rotated back to its original position, releasing the pull rod 12. The positioning spring 14 automatically presses the positioning panel 15 downward onto the surface of the wire, achieving physical compression of the charging cable. This process is simple and intuitive. The pressing force is determined by the spring, which can adapt to cable coils of different thicknesses and rebound forces, ensuring reliable and non-displacement of the limit.

[0032] Compared to traditional on-site manual wrapping, clipping, or plastic binding methods, the limiting mechanism constructed by this device has the advantages of compact structure, simple operation, and strong reusability. It not only improves the standardization of on-site wire management, but also significantly reduces construction risks such as tripping, accidental pulling, and damage caused by messy wires, and has good practicality and engineering adaptability.

[0033] In this embodiment, the surface of the positioning panel 15 is provided with a plurality of anti-slip protrusions 16, and the anti-slip protrusions 16 are made of rubber. This structure further optimizes the limiting and pressing effect on the charging cable and has the following significant advantages:

[0034] First, when the anti-slip protrusion 16 is pressed onto the surface of the charging cable by the positioning panel 15, it can form local point contact pressure. Compared with the planar pressing structure, it can enhance the friction with the surface of the wire, effectively prevent the wire from slipping, displacing or loosening when subjected to external force disturbance (such as vibration, dragging, etc.), and improve the stability of the wire during the limiting process.

[0035] Secondly, the anti-slip protrusion 16 is made of rubber, which has good flexibility and cushioning performance. During the compression process, the rubber can adapt to the slight deformation of cables of different specifications and outer diameters, which not only improves the fit, but also avoids problems such as local pressure damage and sheath wear caused by direct contact of hard materials with the cable surface, thus enhancing the protection effect during the limiting process.

[0036] In addition, the structure also has a certain vibration absorption capacity, making it suitable for high-intensity operations and frequent equipment vibrations on construction sites. This allows the limiting structure to maintain reliability even under harsh working conditions, further improving the overall safety and engineering adaptability of the device.

[0037] In this embodiment, an anti-slip sleeve is fitted onto the middle area of ​​the outer side of the pull rod 12. This design offers the following significant advantages: the anti-slip sleeve significantly enhances the user's grip stability during operation of the pull rod 12. Especially when workers at construction sites wear gloves, have wet hands, or experience dust or oil contamination, the high-friction contact surface provided by the anti-slip sleeve effectively prevents slippage, ensuring smooth and reliable lifting operation, and improving safety and control precision.

[0038] In this embodiment, the surface of the charging cable placement plate 6 is provided with several grooves 5. The grooves 5 can naturally guide and limit the wires placed on the surface of the charging cable placement plate 6, effectively preventing the wires from sliding, overlapping or springing back during the arrangement process, ensuring that the wires can be neatly arranged along the direction of the grooves, and improving the overall neatness and controllability of the storage.

[0039] In this embodiment, the surface of the base plate 1 is provided with a plurality of threaded holes 8, and the surface of the charging cable placement plate 6 is provided with threaded posts 7, which are engaged with the inside of the threaded holes 8. This structure not only achieves a stable connection, but also brings the following multiple technical advantages:

[0040] First, the connection between the threaded post 7 and the threaded hole 8 is a detachable threaded connection, which makes the charging cable placement plate 6 easy to install and remove. Users can flexibly adjust the number and layout of the placement plates 6 according to the space constraints of the construction site or the number of cables used, thereby improving the system's adaptability and modular expansion capabilities.

[0041] Secondly, the structure also features convenient angle adjustment. Due to the rotatability of the threaded connection, users can adjust the depth to which the threaded post 7 is screwed into the threaded hole 8 during installation, or make fine adjustments based on the shim structure, thereby achieving stable positioning of the charging cable placement plate 6 at different tilt angles. This angle adjustment capability is particularly suitable for practical needs such as different construction site terrains and different cable routing directions, making charging cable organization more aligned with on-site workflows, improving user comfort and operational efficiency.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
