[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0028] Please see Figures 1-9This embodiment discloses an insulating toolbox for live-line work of a submersible pump, including a first outer shell 1. A sliding groove 11 is formed inside the first outer shell 1, and a first inner box 12 is slidably connected within the sliding groove 11. Fixed plates 2 are rotatably connected to both sides of the first outer shell 1. Sliding rails 21 are formed on the fixed plates 2, and a second outer shell 3 is slidably connected within the sliding rails 21. Restriction holes 35 are formed on both sides of the second outer shell 3, and a first sliding groove 31 is formed inside the second outer shell 3. The first sliding groove 31 communicates with the sliding groove 11. A second slide 32 is provided on one side of the slide 31. The second slide 32 includes a straight groove 321 and an inclined groove 322. The straight groove 321 is opened inside the first outer shell 1, and the inclined groove 322 is opened inside the second outer shell 3. The straight groove 321 is used to communicate with the inclined groove 322. A second inner box 33 is slidably connected in the first slide 31. Multiple drawers 4 for placing tools are slidably connected in both the first inner box 12 and the second inner box 33. A pull ring 34 is installed on one side of the second inner box 33. The pull ring 34 is used to pull up the second inner box 33.

[0029] Existing live-line working insulated toolboxes for submersible oil pumps present challenges during transformer maintenance. The limited space inside the transformer, coupled with the need to access multiple tools, necessitates repeated bending to retrieve them, causing inconvenience. This new toolbox allows for the stacking of the first outer shell 1 and the second outer shell 3, and enables the inner toolbox to be pulled out to a certain height, facilitating tool selection for maintenance personnel. The first outer shell 1, the second outer shell 3, and the fixing plate 2 form the main structure of the toolbox, providing sufficient strength and stability. The sliding rail 21, slidably connected to the second outer shell 3, allows the second outer shell 3 to slide relative to the first outer shell 1, facilitating subsequent operation of the second outer shell 3. Furthermore, the design of multiple sliding grooves within the first and second outer shells 1 and 3 allows the first inner box 12 and the second inner box 33 to slide within them. The overall structure of the toolbox is robust, protecting the internal tools from damage or loss. The entire toolbox is designed with insulating materials. This submersible pump live-line working insulating toolbox features a reasonable structural design, complete functions, convenient operation, and high safety and reliability, providing strong support and protection for electricians performing live-line work in complex working environments. Example 2

[0030] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 1-9 A fixing post 22 is slidably connected to one side of the fixing plate 2. A first spring 23 is sleeved on the fixing post 22. The first spring 23 is disposed on one side of the fixing plate 2. The fixing post 22 is used to slide with the limiting hole 35.

[0031] A mating block 13 is fixedly connected to one side of the first inner box 12. A fixing groove 14 is provided on one side of the mating block 13. An abutting inclined block 15 is slidably connected inside the mating block 13. One end of the abutting inclined block 15 abuts against a receiving inclined block 16. One end of the receiving inclined block 16 is fixedly connected to a fixing rod 17. The other end of the receiving inclined block 16 is fixedly connected to a second spring 18. The second spring 18 is located inside the first inner box 12.

[0032] The second inner box 33 has a mating groove 37 on one side, which is used to slide with the mating block 13. The second inner box 33 has a first fixing hole 38 on one side, which passes through one side of the mating groove 37.

[0033] The inner side of the first outer casing 1 is provided with a second fixing hole 19, which is used to slide with the fixing rod 17. One end of the limiting hole 35, the first fixing hole 38 and the second fixing hole 19 are all enlarged horn-shaped designs.

[0034] The inner side of the limiting hole 35 is slidably connected to a movable column 39, and the movable column 39 is covered by a third spring 310. The third spring 310 is located inside the first outer shell 1. One end of the movable column 39 is slidably connected to a sliding strip 311, and one end of the sliding strip 311 is fixedly connected to a fixing strip 312. The fixing strip 312 is used to slidably connect with the fixing groove 14 and the first fixing hole 38. One end of the fixing strip 312 abuts against the inclined surface of the abutting inclined block 15.

[0035] A control block 41 is slidably connected to the inside of one side of drawer 4. Both sides of the control block 41 are provided with abutting slopes 42. A control rod 43 is abutted at the slope of the abutting slope 42. One end of the control rod 43 abuts against the inside of the first inner box 12 and the second inner box 33. A fourth spring 44 is connected between the two control rods 43.

[0036] A third slide groove 110 is provided on one side of the first inner box 12. Slide columns 45 are fixedly connected to both sides of the upper drawer 4 inside the first inner box 12. The slide columns 45 are slidably connected to the third slide groove 110, and the slide columns 45 are used to slidably connect with the straight groove 321 and the inclined groove 322.

[0037] A fixing block 313 is slidably connected to the outer side of the second outer shell 3. A trapezoidal inclined block 314 is fixedly connected to one side of the fixing block 313. A fifth spring 315 is fixedly connected to one end of the trapezoidal inclined block 314. The fifth spring 315 is located inside the second outer shell 3. The trapezoidal inclined block 314 is slidably connected to the inside of the second outer shell 3.

[0038] This toolbox can be adjusted for use in various scenarios and according to different situations. First, frequently used tools are placed in drawer 4 of the second inner box 33, less frequently used tools are placed in the upper drawer 4 of the first inner box 12, and occasionally used tools are placed in the lower drawer 4 of the first inner box 12. When the area is large and the tools used are few, and there is no need to bend over frequently to select tools, the toolbox can be placed directly on the ground and the drawer 4 inside the second inner box 33 can be opened to retrieve the tools. When opening the drawer 4, simply press the control block 41 so that the abutting slope 42 on the control block 41 abuts against the control rod 43, causing the control rod 43 to retract and release the fixation of the fourth spring 44, so that the fourth spring 44 can be pulled out. At the same time, through the design of the fourth spring 44, the control rod 43 can return to its initial position afterward. When using many tools and frequently bending over to select them, after placing the toolbox on the ground, pull the fixing post 22 on the fixing post 22 to slide it out of the limiting hole 35. This design allows the first outer shell 1 and the second outer shell 3 to be fixed under the support of the fixing post 22, preventing the second inner box 33 from sliding freely in the sliding track 21, thus restricting the position of the second outer shell 3. After pulling out the fixing post 22, the second outer shell 3 is slid in the sliding track 21, allowing it to be placed on the first outer shell 1. This design increases the height of the toolbox and allows the docking block 13 to be inserted into the docking slot 37. At this time, by swinging the fixing plate 2, the fixing post 22 is inserted into the limiting hole 35. The elastic force of the first spring 23 is much greater than that of the third spring 310. This design allows the fixing post 22 to insert into the limiting hole 35 while simultaneously abutting the movable post 39, causing the movable post 39 to drive the sliding bar 311 to slide. The movement causes the sliding bar 311 to drive the fixing bar 312 into the first fixing hole 38 and the fixing groove 14. At the same time, one end of the fixing bar 312 abuts against the inclined surface of the contacting inclined block 15, causing the contacting inclined block 15 to slide. As the contacting inclined block 15 slides, one end of the contacting inclined block 15 abuts against the inclined surface of the resisted inclined block 16, causing the resisted inclined block 16 to slide. As the resisted inclined block 16 slides, the second spring 18 deforms, and the fixing rod 17 slides out of the second fixing hole 19. This design releases the fixing rod 17 from the first inner box 12, allowing the first inner box 12 to slide within the sliding groove 11. Simultaneously, this design also allows the second inner box 33 to connect with the first inner box 12. When the second inner box 33 is pulled up by the pull ring 34, the first inner box 12 is also pulled up, further raising the positions of both the first and second inner boxes 12. This makes it easier for maintenance personnel to select tools, eliminating the need for frequent bending over. As the first inner box 12 is pulled up, the sliding pillars 45 on both sides of the upper drawer 4 slide in the straight groove 321. When the sliding pillars 45 slide to the inclined groove 322, guided by the inclined groove 322, the sliding pillars 45 slide in the third sliding groove 110, causing the upper fourth spring 44 inside the first inner box 12 to be automatically opened. This design makes it convenient for maintenance personnel to select tools. At the same time, the design of the sliding pillars 45 can also prevent the second inner box 33 from being pulled out of the first inner box 12 due to excessive force. The design of the trapezoidal inclined block 314 allows the protrusions on both sides of the second inner box 33 and the first inner box 12 to slide normally when they collide with the inclined surface of the trapezoidal inclined block 314 in the sliding groove 11 and the first sliding groove 31. When positioning is required, the protrusions collide with the straight surface of the trapezoidal inclined block 314, thus restricting the position of the protrusions and preventing the second inner box 33 and the first inner box 12 from suddenly sliding back into the first outer shell 1 and the second inner box 33 during use. After use, first push the fixed block 313 to slide, so that the trapezoidal inclined block 314 can release the restriction on the protrusion, allowing the second inner box 33 to slide against the first inner box 12. Simultaneously, the design of the fifth spring 315 allows the trapezoidal inclined block 314 to automatically return to its initial state, while also restricting the position of the second inner box 33. The trapezoidal inclined block 314 requires a certain amount of resistance to slide, preventing the second inner box 33 from sliding unnecessarily without external force. Additionally, a protrusion is provided on one side of the second inner box 33. It can abut against the second outer shell 3 to prevent the second inner box 33 from sliding out of the second outer shell 3. This design restricts the position of the second inner box 33 and prevents it from sliding randomly. Then the second inner box 33 is pulled back to the initial position and the fixing post 22 is swung to make the fixing post 22 re-insert into the limiting hole 35 to fix the second outer shell 3. At the same time, the fixing rod 17 is re-inserted into the second fixing hole 19 to restrict the position of the first inner box 12. The funnel-shaped design of each hole facilitates the fit.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
