The specific embodiment
Further specify the specific embodiment of a kind of opencut of the utility model below in conjunction with accompanying drawing, but be noted that the enforcement of the utility model is not limited to following embodiment with the novel procedure lock of high-voltage board isolating switch.
Referring to Fig. 1, and cooperate Fig. 2, a kind of opencut comprises lock body 1, lock core 2, hammerlock 3 and lock pin 4 with the novel procedure lock of high-voltage board isolating switch.
Wherein, T shape passage is arranged in the described lock body 1, transverse passage-way 11 is the lock pin movable passageway, and perpendicular passage 12 is installed and the hammerlock activity space for lock core, and lock body 1 has screw 13 and two installation lock bodies 1 of an installation lock core in circular hole cashier's office in a shop.
Described lock core 2 be a lock core to a key, if key 5 is not corresponding with lock core 2, key 5 can not release, lock core 2 only when locking, just can extract by key 5, during release, key 5 can not be extracted.
Described hammerlock 3 has draw-in groove and installing hole 32, during installation draw-in groove is sticked into outside lock core 2 boss, is fastened on lock core 2 boss both sides with screw, on the radius that hammerlock 3 is fit to, a finger 31 is arranged, and finger can stick into lock pin 4 allocating slots, and hammerlock 3 changes together with lock core 2 and key 5.
Described lock pin 4 is to pack in the transverse passage-way of lock body 1, and the finger groove of the position corresponding with hammerlock finger 31 is arranged on lock pin 4, and key 5 is rotational lock core 2 when last, release, and drives hammerlock finger 31, stirs lock pin 4 by finger 31 and moves and lock or release.
