Performance, the characteristics of semi-automatic insurance furniture built-in lock:

1, after lockset was locked, only when insurance, self-locking state, key just can be extracted, so this lock can not forgotten lock, and had tamper-resistant function;

2, open and close are rapid, and are easy to install;

3, dead bolt has increased the reliability of locking than long 2～4 millimeters of general furniture dead bolt.

Description of drawings:

Fig. 1: outline drawing;

Fig. 2: the locking schematic diagram under the insurance self-locking state;

Fig. 3: the schematic diagram when dead bolt can free in and out;

Fig. 4: dead bolt is the schematic diagram of unblanking of withdrawal all.

Wherein, 1 lock core, 2 dead bolts, the 3 groups of plates, 4 dead bolt grooves, 5 shifting blocks, 6 lockholes, 7 springs, 8 shells, 9 the inners, 10 outer ends.
