Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0018] Reference Figure 1-3 As shown, a security distribution cabinet with line protection function includes a distribution cabinet body 1, a plurality of protective covers 2 are connected to the distribution cabinet body 1, an energy conversion mechanism 3 is connected to the protective cover 2, both sides of the energy conversion mechanism 3 are connected to transmission components 4, both sides of the energy conversion mechanism 3 are further connected to storage components 5, and a control mechanism 6 is further connected to the distribution cabinet body 1; wherein The energy conversion mechanism 3 includes: A double-twisted torque arm assembly 31, wherein an insulating protection assembly 32 is connected to the outer side of the double-twisted torque arm assembly 31; The control mechanism 6 includes: The switch control component 61 is connected to the protective cover 2 body, and the protective cover 2 body is also connected to a display component 62.

[0019] When a short circuit occurs in the circuit, the current in the circuit increases. At the moment of current change, the twisted-pair torque arm assembly 31 generates an induced current. Under the action of the short-circuit current magnetic field, the twisted-pair torque arm assembly 31 that generates the induced current rotates, and the power storage assembly 5 is stored through the transmission assembly 4. When the short-circuit current stabilizes, the transmission assembly 4 is separated from the power storage assembly 5, and the power storage assembly 5 releases the force, causing the switch control assembly 61 to work, disconnecting the power supply, and at the same time, the display assembly 62 is deflected for display.

[0020] Reference Figure 4-6As shown, the insulation protection component 32 includes: The insulating connecting tube 321 includes an outer wall 322 and an inner wall 323 . Both ends of the insulating connecting tube 321 are fixedly connected with protective covers 324 .

The center of the ceramic shaft 312 is fixedly connected to a circuit conducting rod 313.

[0023] When a short circuit occurs in the circuit, the current in the circuit increases and the magnetic field changes, causing the double helix belt 311 to generate an induced current. Under the action of the circuit magnetic field, the double helix belt 311 rotates, thereby driving the insulating connecting tube 321 and the protective cover 324 to rotate.

[0024] Reference Figure 7-8 As shown, the transmission component 4 includes: Ratchet 1 41, said ratchet 1 41 is fixedly connected to the protective cover 324, said ratchet 1 41 cooperates with ratchet 2 42, said ratchet 2 42 is fixedly connected to one end of a transmission shaft 1 43, said transmission shaft 1 43 is rotatably connected in the protective cover 2, the other end of said transmission shaft 1 43 is fixedly connected to one end of a push rod 44, the other end of said push rod 44 is fixedly connected to one end of a transmission shaft 2 45, and the other end of said transmission shaft 2 45 is rotatably connected to a roller 46.

Through the cooperation between the ratchet 1 41 and the ratchet 2 42, the ratchet 2 42 rotates, thereby driving the transmission shaft 1 43 and the push rod 44 to rotate. When the push rod 44 rotates, it drives the transmission shaft 2 45 and the roller 46 to rotate.

[0026] Reference Figure 9 As shown, the power storage component 5 includes: A guide rod 51, the guide rod 51 is fixedly connected to the protective cover 2, a counterweight 52 is slidably connected to the guide rod 51, a spring 53 is provided between the counterweight 52 and one end of the guide rod 51, one end of the spring 53 is fixedly connected to the counterweight 52, and the other end of the spring 53 is fixedly connected to one end of the guide rod 51, the counterweight 52 is fixedly connected to the triangular slider 54, and the roller 46 abuts against the triangular slider 54; and The deflection rod 55 is provided with a slide groove 551, and the counterweight block 52 is fixedly connected with a protruding shaft 521, and the protruding shaft 521 is slidably connected to the slide groove 551. One end of the deflection rod 55 is fixedly connected to the rotating shaft 1 56, and the rotating shaft 1 56 is rotatably connected in the protective cover 2.

[0027] When the roller 46 deflects, it pushes the triangular slider 54 to slide on the guide rod 51, thereby driving the counterweight block 52 to slide together, so that the spring 53 is stretched, and at the same time the deflection rod 55 is deflected, and the rotating shaft 1 56 rotates in the positive direction.

[0029] When the current in the circuit stabilizes and the power storage ends, the shaft 1 56 rotates in the opposite direction under the action of the spring 53, driving the ratchet 4 613 to rotate. Through the adaptation of the ratchet 3 612 and the ratchet 4 613, the ratchet 3 612 rotates, and then drives the shaft 2 611 to rotate.

The sliding rail 618 is fixedly connected to one end of the connecting rod 6181, and the other end of the connecting rod 6181 is fixedly connected to the conduction block 6182.

[0031] One end of the wire in the circuit is connected to the conducting block 6182. When the cam 616 rotates, the protrusion 6171 slides in the slide 6161.

[0033] When the second rotating shaft 611 rotates, it drives a bevel gear 3 621 fixed to it to rotate. Through the meshing action of the two bevel gears 3 621, the rotating rod 622 rotates, and then drives the pointer 623 to rotate.
