Referring to Fig. 7, this lockset also can be equiped with insulation cup (26), the bowl cover (27) that this assembly of liquid switch assembly (II) includes splendid attire conducting liquid (mercury or strong electrolyte), be provided with electric pole plate (28) and lower electrode plate (29) in the cup (26), electric pole plate is fixed with expansion screw on (28), and upper and lower two battery lead plates are as liquid switch (K ₄) two ends be connected electrically in warning music-integrating block (BT by lead ₂) current supply circuit, cup (26) bottom is fixed with orbicule (30), by base (31), base cover (32) this assembly is fixed on the housing (1).

Referring to Fig. 8, the dead bolt device of this lockset includes shell (33), and shell is provided with lock core in (33), reaches the dead bolt (34) by key, lock core controlled motion, and the mechanism of wherein lock core, and lock core control dead bolt motion states because of being that known technology is no longer superfluous.The dead bolt device main feature of this lockset is to have set up automatically controlled dead bolt retainer (III) on the prior art basis again.Automatically controlled dead bolt retainer (III) comprises the insulation sleeve (43) that is connected on the shell (33), bottom in the insulation sleeve (43) is fixed with permanent magnet (35), having above the permanent magnet (35) can be relative to its upper and lower metal lock pin (36) that moves, metal lock pin (36) shaft rod upper sleeve is equipped with magnet exciting coil (L), magnet exciting coil (L) and stop switch (K ₅) and normally closed switch (K ₂) and power supply (E) serial connection formation excitation control loop, that is to say that magnet exciting coil (L) is subjected to K ₂And K ₅The control of two switches.Be manufactured with on the dead bolt (34) can with the chimeric groove (37) of lock pin (36) spindle nose structure.Also be provided with switch drive on the dead bolt device, this mechanism comprises: the cam disc (38) of band keyhole, the cam follower shaft (41) on shell (33) by axle bed (39) and spring (40) elastomeric bearing, this driven shaft end is fixed with switch push pedal (42), the preceding dead bolt stop switch (K that is provided with of switch push pedal (42) ₅) and alarm switch (K ₃), two switches are connected in respectively on the shell (33).

The course of work of this anti-theft puzzle lock lockset is as described below.As common door lock is installed this lockset dead bolt device is installed on the door, and warning device is installed near the dead bolt device, without any mechanically contact, electrical connection is only arranged between the stream oriented device.The setting of the password in the cipher switch assembly is artificial code pins (18) being connected on each cipher chips (7) by predetermined number, and three cipher chips (7) are arranged in this example, then can set the password of 3 bit digital.When using this lockset, if lockset is blocking (state as shown in Figure 8), then the cipher switch assembly conducts electricity, and conducting process is: power supply E → lead → conductive pin (20) → cipher chips (7) → opening metal spacer ring (8) → elastic conducting strip (23), i.e. normally closed switch (K ₂) closed (referring to Fig. 1) can switch on, this moment, if then cam follower shaft (41) displacement contacted alarm switch (K insert interior the rotating cam dish of cam disc (38) of dead bolt device with key after ₃) and stop switch (K ₅), make two switch closures, K ₃Closure is then connected alarm circuit and is produced alarm sound; K ₅Closure then makes magnet exciting coil (L) energising, produce and the opposite magnetic force of permanent magnet (35) magnetic pole, move making under the magneticaction that repels each other on the metal lock pin (36), within the groove (37) on lock pin (36) the spindle nose embedding dead bolt (34), the braking dead bolt is after this only at the K of cipher switch assembly ₂Make magnet exciting coil (L) dead electricity after the outage, under permanent magnet (35) magnetic attraction, lock pin (36) can withdraw from the dead bolt groove.When this lockset is unblanked, at first to untie password, decode procedure is: rotating screw bolt axle (4) at first, three grooves according to its handwheel place delineation align the position that searches out first cipher chips (7), rotational password wheel shaft (5) makes code pins (18) on this cipher chips (7) contact with elastic conducting strip (23) (to feel with hand strength then, or listen and elastic conducting strip (7) collision sound) [referring to Fig. 5], go up numeral by the predetermined yardage alignment of this lock according to the groove reference scale axle sleeve (12) on the password wheel shaft (5) again, be positioned at the finger groove of this cipher chips (7) this moment because of nut pin (6), so password wheel shaft (5) rotates the rotation that can drive cipher chips (7) by nut pin (6), insulating substrate (15) part of this cipher chips (7) then contacts with conductive pin (20) after the yardage alignment, then this cipher chips outage, by above-mentioned decode procedure repetitive operation, all cut off the power supply until three cipher chips, then cipher switch assembly outage, that is K ₂Open circuit, K ₂Open circuit opens circuit the current supply circuit of automatic alarm circuit and magnet exciting coil (L), and can unblank this moment, and no longer reports to the police when unblanking.

Because of manual Warning door bell loop independent utility BT ₁And form independent loop, so any moment no matter is touched K as long as press hand switch axle (25) ₁, BT then ₁Energising produces sound equipment.

If during as door lock, then need not to install liquid switch assembly (II) with this lockset.If with this anti-theft puzzle lock lockset is that removable thing such as case, bag etc. are when locking, then can utilize liquid switch assembly (II) to report to the police, its course of work is referring to Fig. 7, behind the locking objects that will be locked, utilize orbicule (30) that the interior conducting liquid of insulation cup (26) is the level of state, then be off state, K between electric pole plate (28) and the lower electrode plate (29) ₄The outage (see figure 1); If someone moves the locked object body, as long as insulation cup (26) tilts, then conducting liquid is with upper and lower two battery lead plate short circuit, i.e. K ₄Closure, BT ₂Alarm sound is sent in energising.
