Specific implementation mode
As shown, a kind of lock for door of switch cabinet anti-loose structure, including cross sectional shape are the limit catch 3 of U-shaped, limiting block
Be provided with the through-hole 4 that can be passed through for the lock shaft 2 of switchgear or door lock of power distribution cabinet in the middle part of 3 bottom edge of piece, lock shaft 2 and through-hole 4 it
Between be micro- interference fit or clearance fit；The bottom edge range switch cabinet or 1 inner surface of cabinet door for power distributing cabinet for limiting catch 3 have one
Segment distance, limit catch bottom edge middle through-hole is sleeved on the lock shaft of switchgear or door lock of power distribution cabinet, while limiting catch
Lateral plate is closely against on the flanging inner wall of switchgear or cabinet door for power distributing cabinet, and cabinet door, limit catch provide two-point defined line for lock shaft
Formula limits, and is rotated by key actuated lock shaft after driving lock tongue locking or opening cabinet door, caused by the active force applied to key
Shaking trend flexible cannot be shaken because the lateral plate for limiting catch is closely against on the flanging inner wall of switchgear or cabinet door for power distributing cabinet
