The protective shell 8 is made of a fireproof hard material, and the nylon rope 27 is required to have easy breaking property and good tensile property.

The working process of the invention is as follows: in the initial state, the return spring 36 is in a tension state and stores energy, and the two first scroll springs 26 and the second scroll spring 45 are in a compression state and store energy; one end of the rack 17 matched with the hard disk 14 is contacted with the hard disk 14; a male head 49 is inserted into the female head 15, the inner plate inclined plane end of the first expansion plate 32 penetrates through a hole on the lower end face of the female head 15 and is inserted into a limiting groove on the male head 49, and the inner plate inclined plane end of the first expansion plate 32 fixes the relative position of the male head 49 and the female head 15; the two guide blocks 54 are respectively positioned at the top ends of the corresponding guide grooves 53; the male head 49 which is not inserted into the female head 15 is electrically connected with a data transmission line in the distribution box 1; the baffle 11 is vertically positioned at the opening of the protective shell 8; the nylon rope 27 is in a tight state, and the thin steel wire 48 is in a tight state; a part of the nylon rope 27 is vertically positioned on the central axis of the cutting ring 46, and the distance between the thin steel wire 48 and the cutting ring 46 is larger, so that the thin steel wire 48 is prevented from being cut off by the cutting ring 46 when the thin steel wire shakes by a small amplitude. The three thin steel wires 48 are wound in the corresponding winding grooves 44 by a plurality of turns, respectively.

The rear side wall of the distribution box 1 cannot be impacted due to the fact that the rear side wall is close to a wall or other shelters, and only the front side wall, the left side wall and the rear side wall of the distribution box 1 can be impacted; when any one of the front side wall, the left side wall and the rear side wall of the distribution box 1 is seriously impacted, the impacted side wall of the distribution box 1 is seriously deformed, and the seriously deformed side wall of the distribution box 1 acts on the corresponding side wall of the outer shell cover 5 in the data protection storage mechanism 3; the side wall of the outer housing cover 5, which is extruded by the deformed side wall of the distribution box 1, is deformed and dented inwards, and the side wall of the outer housing cover 5, which is deformed and dented, pushes the support ring 42 to move in the same direction along the horizontal direction through a second expansion plate 47 hinged with the support ring; the supporting ring 42 drives the rotating cylinder 43 matched with the bearing of the supporting ring and the cutting ring 46 arranged in the rotating cylinder 43 to synchronously move, and the circumferential saw teeth on the inner wall of the cutting ring 46 meet the nylon rope 27 positioned in the cutting ring; meanwhile, the thin steel wires 48 connected with the deformed side wall of the outer housing cover 5 and the thin steel wires 48 connected with the side wall on the right side of the deformed side wall of the outer housing cover 5 pull the rotating cylinder 43, and the two thin steel wires 48 pulling the rotating cylinder 43 drive the rotating cylinder 43 to rotate rapidly; the rotating cylinder 43 drives the cutting ring 46 to rotate synchronously, so that the cutting ring 46 saws the nylon rope 27 meeting the saw teeth on the cutting ring; the thin steel wire 48 connected to the side wall located at the left side of the deformed side wall of the housing is loosened by the rotation of the rotating cylinder 43.

When the nylon rope 27 is sawn off by the cutting ring 46 which rotates fast, under the action of the pre-stretched return spring 36, the transfer block 28 moves vertically upwards along the trapezoidal guide groove 34, the transfer block 28 drives the second gear 30 to rotate through the first toothed plate 29, the second gear 30 drives the outer plate of the first expansion plate 32 to move vertically downwards through the second toothed plate 31, the outer plate of the first expansion plate 32 drives the inner plate thereof to move synchronously and fast through the two guide blocks 54, and the inclined plane end of the inner plate of the first expansion plate 32 quickly breaks away from the limit groove on the male head 49 and quickly releases the limit on the male head 49; meanwhile, under the action of the pre-compressed first scroll spring 26, the transmission shaft 24 drives the winding wheel 25 and the second belt wheel 21 which are arranged on the transmission shaft to synchronously rotate; the second belt wheel 21 drives the first gear 20 which is coaxial with the first belt wheel 23 to rotate through a synchronous belt 22 and the first belt wheel 23; the first gear 20 drives the rack 17 to rapidly move towards the position of the hard disk 14 along the sliding sleeve 18; the rack 17 pushes the hard disk 14 to rapidly slide out of the mounting square barrel 13, and the female head 15 is rapidly separated from the corresponding male head 49 and disconnected; the hard disk 14 which moves rapidly under the push of the rack 17 pushes the baffle 11 away instantly and enters the protective shell 8; the protective shell 8 moves rapidly along the inserted rod 52 under the rapid impact of the hard disk 14 and is separated from the opening end of the mounting square barrel 13 rapidly; the two plunger rods 52 guide the protective casing 8 into the second outlet 6 on the housing shell 5 and the first outlet 2 on the rear side wall of the distribution box 1; when the protective case 8 is completely separated from the two insertion rods 52 and flies out of the distribution box 1, the protective case falls to the ground; because the outside parcel of protective housing 8 has elasticity refractory wool 12, when the striking of protective housing 8 and ground, the impact that its striking brought is absorbed by having elasticity refractory wool 12, effectively avoids hard disk 14 because of the damage that protective housing 8 and ground striking led to.

When fire breaks out in the distribution box 1, the nylon rope 27 connecting the transmission block 28 and the wire winding wheel 25 is blown, and under the action of the pre-tensioned return spring 36, the transmission block 28 drives the inner plate inclined plane end of the first expansion plate 32 through a series of transmission to remove the limitation on the male head 49 inserted into the female head 15; meanwhile, under the action of the pre-pressed first volute spring 26, the transmission shaft 24 rapidly pushes the hard disk 14 in contact with the transmission shaft to rapidly slide out of the mounting square barrel 13 and enter the protective shell 8 through a series of transmission racks 17, the female head 15 is separated from the male head 49, and the protective shell 8 carries the hard disk 14 to fly out of the second outlet 6 on the shell cover 5 and the first outlet 2 on the rear wall of the distribution box 1 under the impact of the hard disk 14 and falls on the ground; due to the elastic refractory wool 12 wrapped outside the protective shell 8, the hard disk 14 in flame cannot be damaged by high temperature of fire, so that the hard disk 14 storing distribution network data is effectively protected.

In the process that the hard disk 14 enters the protective shell 8, the baffle 11 is pushed by the hard disk 14 to quickly swing upwards to the accommodating groove 9 around the hinge point; after the hard disk 14 completely enters the protective shell 8 and crosses the baffle 11, the baffle 11 swings back to the initial position under the action of self weight and closes the opening of the protective shell 8, so that the hard disk 14 is prevented from sliding out of the protective shell 8, and the hard disk 14 is protected well.

In conclusion, the beneficial effects of the invention are as follows: the data protection storage mechanism 3 in the invention can effectively protect the hard disk 14 for storing data against collision and fire; when the side surface of the distribution box 1 is deformed by external force impact, the side wall of the deformed distribution box 1 impacts the outer shell cover 5 in the data protection storage mechanism 3, any one of the front side wall, the left side wall and the rear side wall of the outer shell cover 5 is impacted to trigger the rope cutting mechanism 41 therein, the triggered rope cutting mechanism 41 cuts the nylon rope 27 connected with the wire winding wheel 25 and the transmission block 28, the transmission block 28 drives the first expansion plate 32 to vertically move downwards through the second gear 30 under the action of the pre-tensioned reset spring 36, and the inner plate inclined plane end of the first expansion plate 32 removes the limitation on the male head 49 inserted into the female head 15; meanwhile, under the action of the pre-pressed first volute spring 26, the transmission shaft 24 drives the first gear 20 coaxial with the first belt pulley 23 to rotate through the second belt pulley 21, the synchronous belt 22 and the first belt pulley 23, and the first gear 20 drives the rack 17 meshed with the first gear to rapidly move towards the first outlet 2 along the sliding sleeve 18; the rack 17 quickly pushes the hard disk 14 in contact with the rack to quickly slide out of the mounting square barrel 13 and enter the protective shell 8, the female head 15 is separated from the male head 49, and the protective shell 8 carries the hard disk 14 to fly out of the second outlet 6 on the shell cover 5 and the first outlet 2 on the rear wall of the distribution box 1 under the impact of the hard disk 14 and falls on the ground; in addition, when fire happens in the distribution box 1, the nylon rope 27 connecting the transmission block 28 and the wire winding wheel 25 is blown, and under the action of the pre-tensioned return spring 36, the transmission block 28 drives the inner plate inclined plane end of the first expansion plate 32 through a series of transmission to remove the limitation on the male head 49 inserted into the female head 15; meanwhile, under the action of the pre-pressed first volute spring 26, the transmission shaft 24 rapidly pushes the hard disk 14 in contact with the transmission shaft to rapidly slide out of the mounting square barrel 13 and enter the protective shell 8 through a series of transmission racks 17, the female head 15 is separated from the male head 49, and the protective shell 8 carries the hard disk 14 to fly out of the second outlet 6 on the shell cover 5 and the first outlet 2 on the rear wall of the distribution box 1 under the impact of the hard disk 14 and falls on the ground; due to the elastic refractory wool 12 wrapped outside the protective shell 8, the hard disk 14 in flame is effectively protected; when the protective shell 8 collides with the ground, the impact caused by the collision is absorbed by the elastic refractory wool 12, so that the damage of the hard disk 14 caused by the collision of the protective shell 8 with the ground is effectively avoided.
