Lock core 46 is installed in the lock body by lock core screw 6, lock

core gear

47 and 40 engagements of gear rocking arm; rocker arm shaft 1, torsion spring pin 45 are fixed on the lock housing 70; gear rocking arm 40 is sleeved on the rocker arm shaft 1; 44 1 of rocking arm torsional springs are installed on the torsion spring pin 45; other end is installed on the gear rocking arm 40, and gear rocking arm 40 also is provided with knuckle 1 and knuckle 2 42; Lock 10, support sliding pin 56 are fixed on the insurance support 55, and support sliding pin 56 is positioned at the chute on the lock housing 70, and tension spring pin 57 is fixed on the lock housing 70, and 58 1 of extension springs are installed on the tension spring pin 57, and the other end hangs on the insurance support 55; Insurer core 52 movable sets are in the hole that lock housing 70 and locking closure 71 are established, insurance Rocker arm 54 is sleeved on the insurer core 52, insurance Rocker arm 54 anterior bending parts connect with the borehole jack that insures on the support 55, separating lock dog 51 is installed on the insurer core 52, release torsion spring 53 is contained in insurance Rocker arm 54 and conciliates between the lock dog 51; rocker arm shaft 2 49 is fixed on the lock housing 70, and latch 48 is fixed on the release rocking arm 2 50, and release rocking arm 2 50 movable sets are in rocker arm shaft 2 49;

When unblanking, key inserts lock core 46 and clockwise rotates an angle, lock core gear 47 driven gear Rocker arm 4s 0, effect lower gear Rocker arm 40 at rocking arm torsional spring 44 turns to another side counterclockwise, knuckle 1 goes to the insurance that inner support 19 is untied by bottom, rotating the handle handle this moment can turn the mandrel 62 of unblanking and drive the piece 61 of unblanking, the arm 60 of unblanking is turned right, thereby promote inner support 19 to the lock body medial movement, compress lock spring 1 and the spring 2 66 of locking, each locking bolt shrinks back in the lock body simultaneously, under the effect of locking pole spring 34, latch 36 withstands on the spacer pin 37, fixes inner support 19, and lock namely is opened; Simultaneously the knuckle 2 42 of gear rocking arm 40 is pushed up at inner support 19 rear portions, makes gear rocking arm 40 swing to again opposite side, and knuckle 1 homing is again recovered the insurance to inner support 19 when so again locking; Doorframe bruising roller 21 when laying the key under the door, roller 21 and frizzen 24 shrink to the inside, push latch 36 to the right at the triggering pin 30 that is installed under the effect that triggers torsion spring 27 in the triggering swing arm 28, drive counterclockwise low-angle of motion of check lock lever 32, trigger pin 30 and withstand the groove at check lock lever 32 middle parts this moment, continue squeezing roller 21, frizzen 24 shrinks to the inside again, therefore oneself can not swing towards the right to trigger swing arm 28 time, but trigger torsion spring 27 and can receive cage, after roller 21 slipped into frame hole section, frizzen 24 ejected under the effect of buffer spring 26, triggered swing arm 28 left swings and drove and trigger pin 30 return in the groove at check lock lever 32 middle parts, thereby check lock lever 32 continues counterclockwise motion, latch 36 skids off from spacer pin 37, the spring 1 of locking, the spring 2 66 of locking ejects inner support 19 and each locking bolt, and lock is namely locked.

When turning clockwise insurer core 52, insurance Rocker arm 54 can promote insurance support 55 and lock 10 stretches out, and lock is namely insured separately; When turning counterclockwise insurer core 52, insurance Rocker arm 54 sides retract lock 10, and the insurance side is opened.

Can be without key when unblank in the door inboard, operate as follows: continue counterclockwise to turn insurer core 52, separating lock dog 51 sides drive release Rocker arm 50 clockwise rotates, latch 48 promotes gear rocking arm 40 and turns to counterclockwise another side, knuckle 1 goes to the insurance that inner support 19 is untied by bottom, can unblank equally.

When locking state, slide block 13 also stretches out lock body, because slide block 13 can slidably reciprocate at guide rod 1, guide rod 2 12, counterbalance spring 15 is pushed into the guide rod outermost end with slide block 13 all the time, thin inboard, compensation block 14 outsides is thick to be sloping shape, compensation block 14 is fixed on the slide block 13, when frame hole one side and slide block 13 gaps hour, frame hole can nip compensation block 14 causes slide block 13 can all not stretch out, if also there is the gap, compensation block 14 can insert the gap, and lock body and doorframe just can not rock yet, and the gap has obtained compensation.
