It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Example 1

[0030] Reference Figure 1-4 A new type of electrical box includes an electrical box body 1 and a box door 2. The box door 2 is installed on one side of the electrical box body 1, and an electrical lining 3 is installed on the inner side of the electrical box body 1.

The top and bottom of the inner side of the electrical box 1 are provided with guide grooves 5 corresponding to the positions of the force-guiding rollers 4. The force-guiding rollers 4 are in close contact with the inner sides of the guide grooves 5. When the electrical lining 3 is pulled, the electrical lining 3 drives the force-guiding rollers 4 to move along the inner sides of the guide grooves 5, so that the electrical lining 3 can be quickly removed.

[0032] The auxiliary maintenance mechanism also includes a quick-release rod 6, a first connecting spring 7, a limit plate 8, a carrying block 9 and a carrying slot 10.

Both ends of the electrical lining plate 3 are provided with a carrying slot 10 corresponding to the position of the carrying block 9. The carrying slot 10 is slidably connected to the carrying block 9, and the end of the carrying block 9 is provided with an inclined surface to facilitate the quick connection of the carrying block 9 and the carrying slot 10 through the inclined surface.

[0033] Example 2

[0034] Embodiment 1 is further optimized, specifically, as Figure 5-7 As shown, the reminder mechanism includes a transmission assembly and a trigger assembly. The transmission assembly is mounted on the inner side of the electrical box 1, and the trigger assembly is mounted on the inner side of the transmission assembly.

[0035] The transmission assembly includes an auxiliary vertical plate 11, an end cap rod 12, a limiting block 13, a rotating rod 14, a second connecting spring 15 and a force-applying pawl 16. The auxiliary vertical plate 11 is fixed at the bottom of the inner side of the electrical box 1 and close to the back of the electrical lining plate 3. The inner side of the auxiliary vertical plate 11 is slidably connected with the end cap rod 12, one end of the end cap rod 12 is in close contact with the electrical lining plate 3, and a limiting block 13 is fixed on the outer side of the end cap rod 12. One end of the limiting block 13 is in close contact with the auxiliary vertical plate 11. One end of the rod 12 is rotatably connected to a roller via a pin, and one end on the inner side of the electrical box 1 is rotatably connected to a rotating rod 14 via a pin. The bottom of the roller is in close contact with the rotating rod 14, and a second connecting spring 15 is fixed to one side of the rotating rod 14. One end of the second connecting spring 15 is fixed to the auxiliary vertical plate 11, and the top of the rotating rod 14 is rotatably connected to a force-applying pawl 16 via a pin. It can be understood that when the electrical lining 3 is in close contact with the end cap rod 12, the second connecting spring 15 is in a stretched state.

[0036] The trigger assembly includes a force transmission ratchet 17, a shaft 18, an L-shaped pointer 19, a mounting seat 20, a U-shaped spring sheet 21, a lower protrusion 22 and a pressure sensor 23.

[0037] A microcontroller 24 and a buzzer alarm 25 are fixed on one side of the box door 2. The microcontroller 24 is electrically connected to the buzzer alarm 25 and the pressure sensor 23 through wires. When the pressure sensor 23 is subjected to pressure, the pressure sensor 23 transmits a signal to the microcontroller 24. The microcontroller 24 processes the signal and sends a start command to the buzzer alarm 25 to remind the user that the electrical box 1 has reached its service life.

[0038] From the above, we can know that:

[0039] The utility model is aimed at the following technical problems: the existing technology can achieve heat dissipation of the electrical box during use, but when the electrical appliances on the surface of the internal electrical lining of the electrical box need to be inspected or repaired, most of the electrical appliances in the electrical box in the existing technology are fixedly installed inside the distribution box. Due to the small internal space of the electrical box, it is inconvenient for the staff to carry out inspection or repair. At the same time, there is a lack of reminders for the number of inspections or repairs, resulting in the phenomenon that some electrical boxes are used beyond their service life; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0040] During use, when it is necessary to inspect or overhaul the electrical appliances on the electrical appliance lining plate 3, the box door 2 is opened, and then the quick-release pull rod 6 is pulled, so that the quick-release pull rod 6 drives the limit plate 8 to squeeze and contract the first connection spring 7, so that the carrying block 9 is separated from the carrying slot 10, and then the electrical appliance lining plate 3 is pulled so that the guide roller 4 moves along the inner side of the guide groove 5, and the electrical appliance lining plate 3 is removed, so that the maintenance personnel can inspect or overhaul the electrical appliances on the electrical appliance lining plate 3;

[0041] When the electrical lining plate 3 is moved out, the electrical lining plate 3 is no longer in contact with the end cap rod 12. At this time, the tension generated by the second connecting spring 15 pulls the rotating rod 14 to rotate, thereby causing the rotating rod 14 to drive the force-applying pawl 16 to move and no longer engage with the force-transmitting ratchet 17. When the electrical lining plate 3 is overhauled, the guide roller 4 is aligned with the guide rail groove 5, and the electrical lining plate 3 is pushed into the inner side of the electrical box body 1. When the electrical lining plate 3 contacts the mounting block 9, the mounting block 9 and the limit plate 8 are pushed to move by the inclined surface on the guide mounting block 9, so that the first connecting spring 7 is squeezed and contracted until the electrical lining plate 3 can continue to move. When the mounting slot 10 contacts the mounting block 9, the elastic force generated by the first connecting spring 7 pushes the limit plate 8 and the mounting block 9 until the mounting block 9 is inserted into the mounting slot 10, thereby completing the fixation of the electrical lining plate 3. At this time, the electrical lining plate 3 again presses against the end cap rod 12, and pushes the end cap rod 12 to move a distance, so that the end cap rod 12 pushes the rotating rod 14 to rotate through the roller, so that the second connecting spring 15 is stretched, and then the force-applying pawl 16 engages the force-transmitting ratchet 17 to rotate a sawtooth amplitude, and the force-transmitting ratchet 17 drives the L-shaped pointer 19 to rotate a sawtooth amplitude. After a long period of multiple maintenance work, when the L-shaped pointer 19 rotates to the raised part on the top of the U-shaped spring sheet 21, the L-shaped pointer 19 squeezes the raised part to produce deformation, so that the raised part pushes the lower raised head 22 to contact with the pressure sensor 23, and the pressure sensor 23 transmits the signal to the microcontroller 24, and the microcontroller 24 processes the signal and sends a start command to the buzzer alarm 25 to remind the user that the electrical box 1 has reached the service life, so as to prevent the safety hazard caused by over-use in the future.

[0042] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0043] 1. The utility model uses the structural design of the auxiliary maintenance mechanism to facilitate the removal of the electrical lining plate 3 for the inspection and maintenance of electrical components, thereby speeding up the work efficiency and improving the flexibility of the device.

[0044] 2. The utility model uses the structural design of the reminder mechanism so that the device can remind the maintenance personnel of the total number of maintenance after a period of time, so as to timely understand the number of maintenance of the electrical box 1 and prevent it from being used beyond the service life.
