Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to fig. 3, the present invention provides a technical solution: a safety distribution box capable of preventing mistaken opening comprises a box body 1, a box door 2 is hinged to the box body 1, two linear locks 3 are arranged on the box door 2, a box opening 4 is formed in the box body 1, a first fixing block 5 is fixedly connected to the inner side of the box door 2, a clamping hole 6 is formed in the outer wall of one side of the first fixing block 5, a second fixing block 7 close to the box opening 4 is fixedly connected to the inner wall of the box body 1, a clamping pin 8 is slidably mounted on the second fixing block 7, an electromagnet suction disc 9 located on one side of the second fixing block 7 is fixedly mounted on the inner wall of the box body 1, one end, far away from the electromagnet suction disc 9, of the clamping pin 8 extends into the clamping hole 6 and is movably connected with the inner wall of the clamping hole 6, a fixing baffle 10 is fixedly connected to one end, close to the electromagnet suction disc 9, of the clamping pin 8 is sleeved with a tension spring 11;

the outer wall of the box body 1 is provided with two threaded blind holes, the threaded blind holes are matched with the I-shaped lock 3, the outer wall of the box body 1 is fixedly connected with four mounting blocks 12 which are distributed in a rectangular shape, the four mounting blocks are provided with mounting holes, the outer wall of one side of the second fixing block 7 is provided with a sliding hole, the bayonet lock 8 penetrates through the sliding hole and is in sliding connection with the inner wall of the sliding hole, the bayonet lock 8 and the fixed baffle plate 10 are made of steel materials, the fixed baffle plate 10, the tension spring 11 and the mounting blocks 12 are matched through the box body 1, the box door 2, the I-shaped lock 3, the box opening 4, the first fixing block 5, the clamping hole 6, the second fixing block 7, the bayonet lock 8, the electromagnet sucking disc 9, the fixed baffle plate 10, the tension spring 11 and the mounting blocks 12, when electronic elements in the box body 1 need to be overhauled, after the electromagnet sucking, then, after the electric power personnel unscrew the two linear locks 3, the box door 2 can be opened; after the overhaul is finished, the box door 2 is closed, the two linear locks 3 are sequentially screwed firmly, then the electromagnet suction cup 9 is closed to operate, the bayonet lock 8 is clamped into the clamping hole 6 in the first fixing block 5 again under the action of the tension spring 11, and the box door 2 is clamped with the bayonet lock 8 through the first fixing block 5, so that the box door 2 cannot be opened even if the two linear locks 3 are opened, and the box door 2 is not provided with a handle, so that the box door is not easy to be violently pulled open and is safer; the utility model discloses the practicality is high, adopts dual fixed mode for chamber door 2 is difficult by the open by mistake, and can avoid chamber door 2 to be pulled open by the violence, and whole security is higher.

The working principle is as follows: the progress coefficient of the tension spring 11 is 5-10N/m, and the free length is 20-25 mm; the model of the electromagnet suction cup 9 is KB-P30/25, and the suction force is 10 kg;

when the power distribution cabinet is used, the ship-shaped switch can be arranged in the power distribution room monitoring room, the ship-shaped switch, the electromagnet sucker 9 and an external power supply are sequentially connected through the conducting wires to form a closed loop, and the four mounting blocks 12 are fixed, so that the box body 1 can be reliably fixed;

when the box door 2 needs to be opened for maintenance, after the relevant electric power personnel reach the side of the box body 1, the personnel in the power distribution room monitoring room are informed to open the ship-shaped switch in a telephone mode, so that the electromagnet sucker 9 can be electrified to generate magnetic force, after the electromagnet sucker 9 receives the suction force, the bayonet lock 8 and the fixed baffle 10 can move rightwards and finally contact with the electromagnet sucker 9, one end of the bayonet lock 8, which is far away from the fixed baffle 10, can exit from the clamp hole 6, so that the first fixed block 5 loses the limitation, and then the electric power personnel can open the box door 2 after the two linear locks 3 are screwed out by using the special key of the linear lock 3;

accomplish the maintenance back, close chamber door 2 on, then in proper order with two word locks 3 twist firmly, inform the power distribution room monitor personnel through the mode of phone afterwards and close ship type switch, electromagnet suction cup 9 loses the appeal after the electricity, under extension spring 11's effect, bayonet lock 8 can move left and block in the card hole 6 on the first fixed block 5 of card, just so accomplished the fixed of chamber door 2, because chamber door 2 forms the card through first fixed block 5 and bayonet lock 8 and holds, so even two word locks 3 are opened, also can't open chamber door 2, and do not set up the handle on chamber door 2, be difficult to the application of force, be difficult for being violently drawn open.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
