Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.
Referring to Fig.1~Fig. 6, a kind of lock core anti-violence forcible entry structure of lockset, including lock body 1, locking bolt 2 and lock core 5, institute
It further includes lockplate 3 and positioning plate 4 to state anti-violence forcible entry structure, and the lockplate 3 is located at the rear of the locking bolt 2, described fixed
Position plate 4 is located between 3 lower part of locking bolt 2 and lockplate；
It is equipped with notch along left and right directions on the left of the middle part of the lockplate 3, the upper left side of the notch is equipped with limiting stand
The upper right of rank, the lockplate 3 is equipped with guiding slot port along upper and lower directions, and the lower part of the lockplate 3 is equipped with abnormal shape
Hole 100, the lockplate 3 are locked by moving up and down be mounted on of cooperation of the first positioning column 7 and guiding slot port on lock body 1
On body 1, the lock body 1 is equipped with locking bolt guide groove in the indentation, there of lockplate 3 along left and right directions, and the locking bolt 2 is equipped with bolt
Plate guide pin 8, the bolt plate guide pin 8 are located in locking bolt guide groove and move left and right pair with the formation of locking bolt guide groove；
The positioning plate 4 is hinged on the left side of lockplate 3 by the second positioning column 6, is used on the positioning plate 4 and lock core
Contact the salient angle 102 of cooperation positioning and the lug 101 for being inserted into lockplate profiled holes 100；Status lock is stretched out in locking bolt 2
After core 5 is removed, 3 free-falling of lockplate and limited step thereon is stuck on bolt plate guide pin 8.
