Described back door lock bracket is installed on the door-plate, and the lock shaft that it is provided with outstanding back door lock bracket fastens with described U-shaped buckle.
In order to strengthen the security reliability of this device, described back door lock bracket is divided into sticking department and fixed part, and fixed part is installed on the door-plate, and sticking department is provided with lock shaft, and an end of sticking department is installed on the fixed part by screw, and described screw passes through door-plate; Is connected by axle between the other end of sticking department and the fixed part, spool is provided with the spring that can force sticking department to sway.
The utility model is made simple, and operation is directly perceived, and square shaft is extended to position, high-tension switch cabinet Qianmen, then can control the unlatching at back door and shut later locking at preceding door operation, only be assembled with several metallic elements, cost be low, process easy, dependable performance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, high pressure voltage switchgear back door interlocking device comprises operating member 2 and back door lock bracket 1.Described operating member 2 is arranged on the Shell Plate 14 of cabinet, it is by U-shaped buckle 5, first locking affects plate 7, connecting rod 8, second locking affects plate 9 and rotates square shaft 10, U-shaped buckle 5 is fixedly connected on first locking by buckle axle 4 and affects on the plate 7, first locking affects plate 7 to be connected by bearing pin 11 with connecting rod 8 one ends, the other end at connecting rod 8 is connected with and can makes connecting rod 8 affect plate 9 in second locking that length direction produces displacement with rotating square shaft 10 rotations by bearing pin 11, second locking affects an end of plate 9 to be fixedly connected with and rotates square shaft 10, and rotation square shaft 10 is vertical with connecting rod 8.
Described back door lock bracket 1 is installed on the door-plate 15, and the lock shaft 17 that it is provided with outstanding lock bracket 1 fastens with described U-shaped plate 5.
In order to strengthen the security reliability of this device, described back door lock bracket 1 is divided into sticking department 18 and fixed part 19, and fixed part 19 is installed on the door-plate 15, and lock shaft 17 is arranged on the sticking department 18, one end of sticking department 18 is installed on the fixed part 19 by screw 16, and described screw 16 passes through door-plate 15; Is connected by axle 20 between the other end of sticking department 18 and the fixed part 19, axle 20 is provided with and can forces the spring of sticking department 18 around axle 20 rotations.
Shut the door, when clockwise rotating square shaft 10, second locking affects plate 9 along with rotation, affecting connecting rod 8 moving linearlies to drive first locking affects plate 7 to make 4 rotations of buckle axle, be contained in the and then rotation of U-shaped buckle 5 of buckle axle 4 ends, when rotating to certain angle, the lock shaft on the back door lock bracket 1 17 pinned, fix tightly square shaft 10 then reaches the purpose with the back door locked.Square shaft 10 also can connect the device that makes energized conductor ground connection simultaneously.
When needs are practiced backdoorism, as long as remove fixing (the making all electrified body deenergizations that the people can touch in the compartment of the affiliated back door of high pressure voltage switchgear simultaneously) of square shaft 10, rotate counterclockwise square shaft 10 (forcing the energized conductor earthing device action that links together to make energized conductor reliable ground in the compartment of affiliated back door simultaneously), U-shaped buckle 5 is turned back to original position, then the back door latch-release can be realized the purpose at clean boot back door.
If the mechanism of device breaks down, perhaps be badly in need of and the back door will be opened, as long as the screw on the back door 16 is outwarded winding, under can driving at the active force of spring, rotate 18 of sticking departments on the back door lock bracket 1 around axle 20, make lock shaft 17 eject the gap of U-shaped buckle 5, then can remove the locking at back door, the back door then can unconventional or emergency opening.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
