[0038] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0039] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figures 1-5 As shown, a preferred embodiment of the electrical equipment maintenance device of this utility model includes a toolbox 1, a base 2, and a height adjustment structure 3;

[0042] The height adjustment structure 3 includes a first connecting rod 31, a second connecting rod 32, a first connecting block 33, and a first threaded rod 34. One end of the first connecting rod 31 is rotatably connected to the toolbox 1, and the other end of the first connecting rod 31 is rotatably connected to the first connecting block 33. One end of the second connecting rod 32 is rotatably connected to the first connecting block 33, and the other end of the second connecting rod 32 is rotatably connected to the base 2. The first threaded rod 34 is threadedly connected to the first connecting block 33.

[0043] Toolbox 1 has a box space 11 for accommodating electrical repair tools.

[0044] Based on the above solution, this embodiment utilizes a height adjustment structure 3 composed of a first connecting rod 31, a second connecting rod 32, a first connecting block 33, and a first threaded rod 34. Users only need to rotate the first threaded rod 34 to quickly and stably change the height of the toolbox 1 relative to the base 2, precisely adjusting the position of the working plane to meet the height requirements of operators of different heights or different maintenance tasks. This allows tools to be positioned at the most ergonomic or specific maintenance angle, significantly improving operational comfort and convenience, reducing operator fatigue, and increasing maintenance efficiency. The threaded rod-driven adjustment method is simple in structure, intuitive in operation, and labor-saving, requiring only the screwing of the threaded rod. The threaded engagement provides precise height control, allowing users to adjust to the optimal working position, especially suitable for electrical maintenance scenarios requiring precision operation or stable support. Once adjusted, the linkage structure exhibits excellent self-locking and rigid support characteristics, reliably supporting the weight of the toolbox 1 and its internal tools, providing a stable working platform and effectively preventing the toolbox 1 from shaking or accidentally falling during operation, thus improving equipment safety. Simultaneously, the base 2 provides stable bottom support for the entire device. This height-adjustable structure has a streamlined three-component design, is simple and reliable, easy to manufacture and assemble, and helps control production and maintenance costs.

[0045] Furthermore, there are at least two first connecting rods 31 and at least two second connecting rods 32. The at least two first connecting rods 31 are rotatably connected to both sides of the first connecting block 33, and the at least two second connecting rods 32 are rotatably connected to both sides of the first connecting block 33.

[0046] By adding a completely symmetrical third connecting rod 35, fourth connecting rod 36, second connecting block 37, and second threaded rod 38, a left-right symmetrical layout is formed with the first connecting rod 31, second connecting rod 32, first connecting block 33, and first threaded rod 34. When the first threaded rod 34 and second threaded rod 38 are fixedly connected and rotate synchronously, the first connecting block 33 and second connecting block 37 are driven to move synchronously in opposite directions. This design ensures that the toolbox 1 is subjected to completely balanced forces on both sides during lifting, completely eliminating tilting, jamming, or asynchrony problems that may be caused by unilateral drive, making the height adjustment process extremely smooth and providing an absolutely stable working platform for precision electrical maintenance. Multiple connecting rods jointly support the weight of the toolbox 1, forming a redundant support structure. Compared to only setting the first connecting rod 31 and second connecting rod 32, its bending stiffness and torsional stiffness are greatly improved, which can safely support heavier tool sets or equipment components and effectively suppress vibration and deformation. Even under high load or asymmetrical tool loading and unloading, the platform can still maintain super stability, avoiding accidental shaking that interferes with maintenance operations. The symmetrical reverse thread design generates opposing but equal resistance torques in both connecting blocks during adjustment, effectively canceling each other out. Users only need to apply minimal rotational torque to drive the entire mechanism up and down, making operation easy and effortless, especially suitable for maintenance scenarios involving long-term or frequent adjustments. The dual self-locking effect of the two sets of threaded pairs significantly improves the reliability of locking the mechanism at any height. Even in the event of unexpected impacts or vibrations, it absolutely prevents height slippage, ensuring operational safety. The load is evenly distributed on both sides of the mechanism, avoiding excessive wear or fatigue damage caused by stress concentration on one side. Simultaneously, the symmetrical design reduces the load on individual kinematic pairs, extending the service life of the threaded rod and the threaded holes of the connecting blocks, and reducing maintenance requirements.

[0047] Furthermore, the height adjustment structure 3 also includes a third connecting rod 35, a fourth connecting rod 36, a second connecting block 37, and a second threaded rod 38. The second threaded rod 38 is fixedly connected to the first threaded rod 34. One end of the third connecting rod 35 is rotatably connected to the toolbox 1, and the other end of the third connecting rod 35 is rotatably connected to the second connecting block 37. The other end of the third connecting rod 35 is rotatably connected to the base 2, and the second threaded rod 38 is threadedly connected to the second connecting block 37.

[0048] The threads of the first threaded rod 34 and the second threaded rod 38 are opposite in direction, and the threads of the first connecting block 33 and the second connecting block 37 are also opposite in direction.

[0049] Multiple first connecting rods 31 and multiple second connecting rods 32 can completely avoid the risk of single-point failure caused by a single first connecting rod 31 or a single second connecting rod 32. When a member on one side breaks unexpectedly, its diagonal member immediately bears the entire load through an internal force redistribution mechanism, ensuring that the toolbox 1 has zero possibility of tipping over.

[0050] Furthermore, the height adjustment structure 3 also includes a handle assembly 39; the handle assembly 39 includes a fixing block 391, a turntable 392, and a handle 393. The fixing block 391 is fixedly connected to the side of the first threaded rod 34 away from the second threaded rod 38, and the fixing block 391 is fixedly connected to one side of the turntable 392. The handle 393 is fixedly connected to the other side of the turntable 392. The fixing block 391 and the handle 393 are not coaxially arranged. The handle 393 is installed on the edge of the turntable 392, forming a lever mechanism with the axis of the threaded rod, which facilitates the operator to rotate the first threaded rod 34 and the second threaded rod 38.

[0051] Furthermore, the base 2 includes a base plate 21 and a surrounding plate 22. The surrounding plate 22 is fixedly connected to the base plate 21. The surrounding plate 22 and the base plate 21 together form a storage space 23. The storage space 23 is used to accommodate the first connecting rod 31, the second connecting rod 32, the first connecting block 33, and the threaded rod.

[0052] The enclosed storage space 23 formed by the enclosure 22 and the base plate 21 allows precision moving parts such as the first connecting rod 31, the second connecting rod 32, the first connecting block 33, the first threaded rod 34, the third connecting rod 35, the fourth connecting rod 36, the second connecting block 37, and the second threaded rod 38 to be completely concealed when not in use.

[0053] Furthermore, the enclosure 22 is provided with an opening slot 221 for rotating the handle 393. The opening slot 221 provided in the enclosure 22 precisely defines the spatial matching relationship between its contour and the motion envelope of the handle 393, while maintaining the sealing of the storage space 23, and provides a non-interference motion channel for the rotation of the handle 393 in the stored state, so that the user can pre-adjust the height without unfolding the device.

[0054] Furthermore, the toolbox 1 includes a box body 12 and a box lid 13. The box lid 13 is rotatably connected to the box body 12 and covers the top of the box body 12. The box body 12 and the box lid 13 together form a box space 11. A handle 14 is fixedly connected to the side of the box lid 13 away from the box space 11.

[0055] The lid 13 is rotatably connected, allowing for quick one-handed access to tools; the handle 14 is ergonomically designed for easy handling and convenient tool transfer. The box body 12 and lid 13 form a closed space, isolating dust, liquids, and other contaminants, protecting precision tools, and extending their service life. The rotatable connection and handle 14 design ensure a stable structure, enabling it to withstand bumpy transport and complex working environments.

[0056] Furthermore, the toolbox 1 includes a lighting assembly 15, which includes a lamp 151 and a telescopic rod 152. One end of the telescopic rod 152 is fixedly connected to the side of the box cover 13 away from the box space 11, and the lamp 151 is fixedly connected to the other end of the telescopic rod 152. The telescopic rod 152 can be freely adjusted in length and angle, allowing the lamp 151 to be flexibly adjusted in position. Whether it is deep maintenance in a narrow space or viewing electrical equipment at a high position, the light can be accurately projected onto the work point, solving the problem of blind spots in traditional fixed light sources. This provides clear and sufficient local lighting for maintenance personnel, ensuring the accuracy of maintenance operations. There is no need to carry additional lighting equipment, and the lighting angle and range can be adjusted at any time during maintenance, avoiding wasted time due to frequent changes in lighting position or waiting for auxiliary lighting to be in place. This allows maintenance personnel to focus on equipment maintenance, significantly improving work efficiency, and is especially suitable for emergency repairs and other time-sensitive scenarios.

[0057] Furthermore, the toolbox 1 includes a plurality of spaced partitions 16, all of which are fixedly connected to the box body 12 and divide the box space 11 into a plurality of placement slots 111.

[0058] Multiple partitions 16 divide the box space 11 of the toolbox 1 into independent storage slots 111, allowing for scientific classification and storage of electrical maintenance tools according to their type, size, and frequency of use. For example, hand tools such as screwdrivers and wrenches can be stored separately from precision instruments such as multimeters and test pens, avoiding cluttered storage and ensuring a neat and orderly internal layout of the toolbox 1. This facilitates quick location of the required tools by maintenance personnel. The clear partitioning design significantly improves tool retrieval efficiency. Maintenance personnel no longer need to rummage through a messy pile of tools and can quickly find the corresponding tool in the storage slot 111, significantly reducing tool search time. This is especially important in emergency maintenance tasks, allowing for faster equipment repair and effectively improving the timeliness of maintenance work.

[0059] Furthermore, a plurality of hanging rings 17 are provided at intervals on the side of the lid 13 near the box space 11, and / or a plurality of storage bags 18 are provided at intervals on the side of the lid 13 near the box space 11.

[0060] The hanging ring 17 and storage bag 18 on the inside of the lid 13 make full use of the unused space above the box, achieving three-dimensional storage inside the toolbox 1. The hanging ring 17 can hang tools with handles such as screwdrivers and pliers, while the storage bag 18 is suitable for storing small parts, instruction manuals, and other items. This complements the placement slot 111 within the box space 11, significantly increasing the storage capacity of the toolbox 1 and meeting the needs of maintenance personnel to carry more tools and accessories.

[0061] In summary, this utility model provides an electrical equipment maintenance device. Through a height adjustment structure 3 composed of a first connecting rod 31, a second connecting rod 32, a first connecting block 33, and a first threaded rod 34, the user can quickly and stably change the height of the toolbox 1 relative to the base 2 simply by rotating the first threaded rod 34, precisely adjusting the position of the working plane to meet the height requirements of operators of different heights or different maintenance tasks. It can position the tools at the most ergonomic or specific maintenance angle, significantly improving operational comfort and convenience, reducing operator fatigue, and increasing maintenance efficiency. The threaded rod-driven adjustment method is simple in structure, intuitive in operation, and labor-saving, requiring only the screwing of the threaded rod. The threaded engagement provides precise height control, allowing the user to adjust to the optimal working position, especially suitable for electrical maintenance scenarios requiring precision operation or stable support. After adjustment, the connecting rod structure has good self-locking and rigid support characteristics, reliably supporting the weight of the toolbox 1 and its internal tools, providing a stable working platform and effectively preventing the toolbox 1 from shaking or accidentally falling during operation, thus improving the safety of equipment use. Meanwhile, base 2 provides stable bottom support for the entire device. The height adjustment structure 3 features a streamlined number of components, a simple and reliable structure, and is easy to manufacture and assemble, helping to control production and maintenance costs.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
