[0036] At the beginning, the elastic force of the two springs 19 causes the outer ends of the two slide bars 18 to contact the inner side wall of the elastic explosion-proof membrane 6. At this time, the plurality of push rods 20 are located in the two annular slide grooves 17, and the outer end of one slide bar 18 is pressed through the elastic explosion-proof membrane 6 to move the slide bar 18 inward. The slide bar 18 drives the plurality of push rods 20 to move inward. Since the outer ends of the plurality of inclined slide grooves 16 are deeper than the outer ends of the plurality of vertical slide grooves 15, the plurality of push rods 20 move inward along the respective The multiple inclined grooves 16 slide, thereby squeezing and rotating the drive ring 13. When the multiple push rods 20 reach the inner ends of the multiple inclined grooves 16 respectively, since the inner ends of the inclined grooves 16 are shallower than the inner ends of the vertical grooves 15, the multiple push rods 20 enter the multiple vertical grooves 15 respectively. When the elastic explosion-proof membrane 6 is released, the elastic force of the second spring 19 pushes the second slide rod 18 outward to reset, so that the second slide rod 18 drives the multiple push rods 20 to move outward. In this process, the multiple push rods 20 are divided into When the plurality of push rods 20 reach the outer ends of the plurality of vertical slide grooves 15 respectively, they return to the annular slide groove 17, and the above operation is repeated to make the drive ring 13 rotate step by step. The drive ring 13 drives the rotating wheel 11 to rotate through the gear ring 14 meshing with the gear ring 12. The rotating wheel 11 rubs the knob of the electrical component to make the knob rotate to a specified position, thereby adjusting the equipment. In the above process, the plurality of push rods 20 on the other slide bar 2 18 are located in the annular slide groove 17 of the other drive ring 13, so that the other drive ring 13 is in a free state, so that the other drive ring 13 will not block the rotation of the rotating wheel 11; because the inclination directions of the plurality of inclined slide grooves 16 on the two drive rings 13 are opposite, the rotating wheel 11 is driven to rotate clockwise or counterclockwise when the two slide bars 2 18 are pressed, so that the knob rotation of the electrical component is operated through the elastic explosion-proof membrane 6, which is practical.

[0037] Embodiment 4, as Fig.11 and Fig.12As shown, on the basis of Example 1, the operating assembly includes a slide rail frame 21, a dial plate 22, a slide bar 3 23, a wedge 1 24, a spring 3 25, a slide bar 4 26, a wedge 27 and a spring 4 28.

The inner end of the slide bar 3 23 is slidably inserted into the inner plate 3, and the outer end of the slide bar 3 23 is installed with a wedge 1 24, and the wedge 1 24 is located at the long slide In the groove, the outer end of wedge block 1 24 contacts the inner wall of the elastic explosion-proof membrane 6, and a wedge-shaped surface 1 matching the inclined surface is set at one end of wedge block 1 24 facing the slot. One end of spring three 25 is connected to the inner plate 3, and the other end of spring three 25 is connected to wedge block 1 24. The inner end of slide rod four 26 is slidably inserted into the inner plate 3, and the outer end of slide rod four 26 is installed with wedge block two 27.

One end of spring four 28 is connected to the inner plate 3, and the other end of spring four 28 is connected to wedge block two 27.

[0038] The wedge block 24 is pressed through the elastic explosion-proof membrane 6, so that the wedge-shaped surface 1 of the wedge block 24 squeezes the inclined surface of the end of the dial plate 22 close to the slot, thereby pushing the dial plate 22 to one side of the slot, so that the dial plate 22 pushes the lever of the electrical component through the slot, and the elastic explosion-proof membrane 6 is released. The elastic force of the spring three 25 causes the slide bar three 23 and the wedge block 24 to move outward and reset, so that the lever is pulled to perform a positive operation on the electrical component, and the wedge block 27 is pressed through the elastic explosion-proof membrane 6, so that the wedge-shaped surface 2 of the wedge block 27 squeezes the inclined surface of the end of the dial plate 22 away from the slot, thereby pushing the dial plate 22 to the other side of the slot, so that the dial plate 22 pushes the lever of the electrical component through the slot, and the elastic explosion-proof membrane 6 is released. The elastic force of the spring four 28 causes the wedge block 27 and the slide bar four 26 to move outward and reset, so that the lever is pulled to perform a reverse operation on the electrical component, thereby realizing the rotation of the lever of the electrical component operated through the elastic explosion-proof membrane 6, which is practical.

At this time, the sealing frame 4, the explosion-proof plate 5 and the elastic explosion-proof membrane 6 close the opening of the box body 1, so that the electrical components are still in the sealed chamber when operating the electrical components, so that the electric sparks generated by the electrical components at the moment of power on and off do not contact the outside air, so that the distribution box still maintains the explosion-proof effect when the electrical components are operated. Finally, when it is necessary to urgently cut off the power supply of the equipment, press the magnetic block 2 41, so that the inner end of the magnetic block 2 41 is close to the explosion-proof plate 5, so that the magnetic block 2 41 attracts the magnetic block 1 40 to move outward, so that the inner end of the magnetic block 1 40 releases the hook plate 38, and the elastic force of the spring 5 39 pushes the hook plate 38 to move along the slide rail 37, so that the hook plate 38 toggles the lever of the main power switch, thereby urgently and quickly cutting off the switch of the main power.
