DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] See also Figures 1 to 3 , the utility model embodiment includes:

[0019] A cabinet emergency unlocking device for a high-voltage power distribution cabinet comprises a lock body 10, wherein the lock body 10 is installed on a right cabinet door 1, and a lock tongue 8 of the lock body 10 cooperates with a lock buckle 9 on a left cabinet door 1 after being extended, thereby locking the door.

[0020] The device also includes a quick door opening structure, which can quickly open the cabinet door 1, so that the operator can perform maintenance and rescue in time, reducing the risk to a minimum.

[0021] The quick door opening structure includes a rotating structure for rotating the lock body 10 and an adjusting structure for moving the rotating structure. The rotating structure is installed on the cabinet door 1 on the lock body 10 side, and the adjusting structure is installed on the cabinet door 1 on the lock buckle 9 side.

[0022] The rotating structure includes a mounting groove 2 and a turntable 3. The mounting groove 2 is opened on the cabinet door 1 on the side of the lock body 10. The turntable 3 is installed at the center of the mounting groove 2 through a rotating shaft. The lock body 10 is installed on the turntable 3. The angle of the lock body 10 can be adjusted as the turntable 3 rotates.

[0023] The side wall of the turntable 3 is provided with a plurality of buckles 4, and the buckles 4 are rotatably connected to the side wall of the turntable 3 through a short shaft with a torsion spring 5. The buckles 4 are arranged tilted, and each buckle 4 is provided with a clearance groove 7 on the side wall of the turntable 3 at its tilted direction. When the turntable 3 rotates, the buckles 4 are pressed into the clearance groove 7 along the action line of the limiting rod 6, so that the turntable 3 can rotate. After passing the previous limiting rod 6, the buckles 4 are lifted up under the action of the torsion spring 5 until the buckles 4 are clamped by the next limiting rod 6, and the turntable 3 stops rotating.

[0024] In this embodiment, the number of the buckles 4 is four, and the four buckles 4 are distributed in a circular array with the turntable 3 as the center.

[0025] A limiting rod 6 is provided at each of the buckles 4 in the installation slot 2 , and the limiting rod 6 is used to position the rotation angle of the turntable 3 .

[0026] The adjustment structure includes an arc groove 13 and a slider 12 with a protrusion 11. The arc groove 13 is arranged on the cabinet door 1 on the side of the lock 9. The slider 12 is slidably connected to the arc groove 13. The arc groove 13 is provided with a retaining edge 14. The retaining edge 14 can prevent the slider 12 from sliding out of the arc groove 13 during the sliding process.

[0027] The cabinet doors 1 on the left and right sides adopt an asymmetric structure that cooperates with each other. The cabinet door 1 near the lock body 10 is provided with a matching edge 15. The matching edge 15 enables the lock tongue 8 to be integrated vertically with the ground when the slider 12 slides to the lowest point, and its left side edge is collinear with the connection between the two cabinet doors 1.

[0028] During emergency unlocking, the protrusion 11 is controlled to make the slider 12 move from top to bottom. At this time, the slider 12 pushes the lock tongue 8 to drive the lock tongue 8 turntable 3 to rotate counterclockwise. After rotating 90°, the lock tongue 8 is perpendicular to the ground, and the cabinet door 1 can be quickly opened.

[0029] When locking the cabinet door 1 again, the turntable 3 needs to be rotated 270° counterclockwise and then locked using a key.

[0030] Different from the prior art, the utility model is a cabinet emergency unlocking device for a high-voltage power distribution cabinet. The device has a quick door opening structure and can quickly open the cabinet door 1, so that the operator can perform maintenance and rescue in time and minimize the risk.
