Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
In fig. 1, 2, 3: the lock comprises a cover body 1, a padlock plate 2, a lock 3, a limiting tongue 4, a main circuit breaker 5, an observation hole 6, a padlock hole 7, a waist hole 8, a fixing column 9, a lock locking nut 10, a connecting plate 11, a driving piece 12, a driving waist hole 13, a toggle lever 14, a detection hole protection plate 15, a detection hole 16, a screw 17, a guide pillar 18 and a sliding waist hole 19.
Embodiment 1, this device cooperation distribution box uses, the box is connected with lid 1, lid 1 is equipped with observation hole 6, observation hole 6 with install in 5 positions of main circuit breaker in the box correspond, safe type elevator block terminal still includes padlock board 2, stirs lever 14, padlock board 2 is equipped with waist hole 8, lid 1 is equipped with fixed column 9, waist hole is arranged in to fixed column 9, waist hole 8 with fixed column 9 sliding connection, lid 1 swing joint has stir lever 14, when tool to lock 3 is in the same direction as, during the anticlockwise rotation, spacing tongue 4, padlock board 2 synchronous concertina movement. The toggle lever 14 swings along an arc-shaped track, the padlock plate 2 swings along the arc-shaped track of the toggle lever 14 to move telescopically, when the waist hole 8 slides to one side of the fixed column 9, the padlock plate 2 extends out of the boundary of the cover body 1, at least three padlock holes 7 are exposed, and meanwhile, the limiting tongue 4 extends out, so that the upward shifting of a closing switch of the main circuit breaker 5 can be prevented; when the waist hole 8 slides to the other side of the fixed column 9, the padlock plate 2 contracts into the boundary of the cover body 1, and meanwhile, the lock tongue 4 contracts into the cover body 1, and at the moment, a closing switch of the main circuit breaker 5 can be pulled up.
