Operating principle of the present utility model:
One, the normal unlatching
The key of use and this lock coupling was opened lockset in the time of setting, and the triggering part in the lockset moves and promote to start link rod to lock core inside under the certain speed promotion of key, and drive isolator, buffer gear rotate.Buffer gear is rotated in the forward on the housing of front end and is connected with linkage lever by a connecting rod, with a fulcrum on the lock body is that linkage lever is rotated in the center of circle, because of this linkage lever is connected with latch piece, therefore the forward rotation of linkage lever just spurs latch piece and moves a bit of distance, blocking mechanism on latch piece and the kayser dish is broken away from, this moment rotary locking cylinder, just dead bolt just returns in the lock body under the effect of driving lever, finishes the process of unblanking.
Two, unnormal unlocking
Trigger part under original state all in occupation of the lock core hole position, if adopt foreign matters such as iron wire, tooth bar, cleek, master key to open locksets, lock core marble is matched arrange before, will trigger part earlier and push in the guide sleeve fully.(1) slowly push and trigger part and carry out pellet shot from a slingshot when arranging, can drive isolator and rotate though trigger the displacement of part, can't drive linkage lever than jogging speed and rotate under the effect of buffer gear, promptly latch piece and kayser dish are in self-locking state all the time; (2) trigger part and touch the buffer gear motion as pushing in setting-up time with certain speed with other modes, if in limiting time, do not open lockset, even blocking mechanism can break away from, but under the effect of buffer gear and linkage lever return spring, in setting-up time, latch piece returns to original position again, and latch piece and kayser dish still keep self-locking state, also can't open lockset even if arranged lock core marble this moment.At this moment, trigger part and rest on lock body inside under the effect of isolator, refusal reuses foreign matter and triggers, and when needing normal the unlatching, can get back to the lock core normal position by the boot trigger part with key, normally opens.
Advantage of the present utility model is:
By triggering the cooperation of part, buffer gear, linkage lever, time adjustment screw, blocking mechanism, successfully open the time of lockset after can inserting the speed of lock core and insert lock core key (foreign matter) and set.No matter adopt which kind of way and which kind of instrument, as long as do not promote to trigger part and rotary locking cylinder in the time that limits, lockset is all keeping self-locking state, has stopped the unnormal unlocking of stealer thus, promptly prevent to use multiple instrument pirate of the open, reach the antitheft purpose of design of prescribing a time limit.
