Specific implementation mode
As shown, the switchgear lock tongue guider of the embodiment of the present invention one, including it is located at door of switch cabinet open side
Column 1, position corresponding with cabinet door door lock is equipped with lock tongue limiting plate 2 on column 1, and lock tongue limiting plate 2 is dislocation bending
The zigzag plate of composition, 2 side of lock tongue limiting plate are that can be connected through a screw thread the positioning section 3 being fixedly connected with switch cabinet vertical pole,
The other side is the limit section 4 with lock tongue limiting slot 5, is connected as one by vertical connection section between limit section 3, positioning section 4；
4 middle part of limit section is provided with to rotate around lock shaft for lock for door of switch cabinet lock tongue and stretch into lock the longitudinal spacing slot 5 of cabinet door, limit
Position slot 5 is provided at both ends with one section of inclined guide surface 6 on the side in cabinet door direction so that part of the limiting slot 5 close to upper end
Width is more than limiting slot stage casing width, constitutes guide groove structure, and lock tongue 9 stretches into limit around the rotation of lock shaft 10 when door of switch cabinet is closed
When in the slot 5 of position, the guide groove structure of lock tongue limiting plate can provide guiding for Door-lock bolt, and 9 angle position of lock tongue initially enters
Width is more than in the guide groove structure of limiting slot stage casing width, can adapt to position dimension error, and lock tongue continues to rotate around lock shaft,
Lock tongue progresses into the fully locked cabinet door in limiting slot stage casing along guide groove, easy to operate.
Positioning section 3, linkage section, limit section 4 are the overall structure being made up of one-pass molding sheet metal, are manufactured
It is simple for process, it is connected by arc transition between each section, prevents right angle tip is exposed from causing security risk, stress collection is also not present
