Utility model content
The technical problems to be solved in the utility model is to provide a kind of for door latch apparatus in examination and repair for high-pressure switch gear room, ensure that just can open switch gear room Zhong Men after insulating slab must be installed by maintenance personal just keeps in repair or safeguard, thus greatly reduce the generation of security incident.
The technical solution of the utility model is:
A kind of for door latch apparatus in examination and repair for high-pressure switch gear room, include flap, rotating shaft, connecting rod and locking bar, described flap rotates and is installed in rotating shaft, the bottom of flap is connected by the first connecting axle with the top of connecting rod, the bottom of connecting rod is connected by the second connecting axle with the inner of locking bar, the outer end of described locking bar is provided with the locked groove be connected with the snap fit on switch gear room Zhong Men, and locking bar is rotationally connected with on fixed bar.
In described maintenance switch gear room, door latch apparatus also includes L shape junction plate, and the horizontal part of L shape junction plate is fixedly connected with the bottom of connecting rod, and the bottom, vertical portion of L shape junction plate is connected by connecting axle with the inner of locking bar.
The bottom of described connecting rod is provided with annular deck, on connecting rod and the top being positioned at annular deck is set with limiting plate, described connecting rod is set with returning spring between annular deck and limiting plate.
The top end face of described flap is circular arc tangent plane, and circular arc tangent plane is towards switch gear room Zhong Men.
Described locking bar is provided with row's installing hole, one end of described fixed bar is inserted and is wherein rotationally connected with locking bar after an installing hole.
Advantage of the present utility model:
The utility model is installed in switch gear room's cabinet, when insulating slab does not insert in cabinet, the locked groove of its locking bar is connected with the snap fit on switch gear room Zhong Men, switch gear room Zhong Men is locked, after insulating slab inserts, flap drives locking bar to rotate by transmission mechanism, and the snap close on the locked groove of locking bar and switch gear room Zhong Men departs from, and switch gear room Zhong Men can open; Flap tip designs of the present utility model is arc tangent plane, ensures to fit with arc tangent plane after inserting all the time in insulating slab the inner, reduces frictional force between the two, reduce operation easier.The utility model structure is simple, easy for installation, ensure that just can open switch gear room Zhong Men after insulating slab must be inserted cabinet by maintenance personal just keeps in repair or safeguard, thus greatly reduces the generation of security incident.
