The specific embodiment

The utility model relates to a kind of lock, and it is realized to destroying the acoustic alarm that has of lockset behavior, to play the effect of intimidateing the saboteur by built-in circuits for triggering and warning circuit.Below in conjunction with accompanying drawing, feature of the present utility model is elaborated:

Fig. 1 is the stereogram of the utility model structure, and Fig. 2 is its exploded view.With reference to Fig. 1,2, lock of the present utility model comprises lock body 1, locking bar 2, tapered end 3, latch 4, phonation circuit 5, circuits for triggering 6 wireless receiving circuits 7, on-off circuit 8, power supply 9 and cover plate 10; Wherein, the lockhole 101 that has an end that holds locking bar 2 on the lock body 1, also be provided with tapered end 3 in the lock body 1, tapered end is corresponding with lockhole 11 positions, the other end of locking bar 2 articulates by latch 4 and lock body 1, in order to realize that the other end can leave lockhole 101 when locking bar 2 serves as the axle rotation with an end that links to each other with latch 4.

Certainly, locking bar 2 can have various ways, as be the U-shape sword iron shown in Fig. 1,2, the fit system of itself and lock body 1 also can have multiple, as articulating by latch for Fig. 1,2 described ends, other end rotation turnover lockhole also can be an end and connects by elastic component, and the other end vertically passes in and out lockhole.

Be provided with groove in the lock body 1, be provided with warning circuit in the groove, groove is provided with cover plate 10, and its cover plate and groove are connected.

The schematic diagram of warning circuit 200 can be referring to Fig. 3 in this specific embodiment, and as shown in Figure 3, power supply 9 is electrically connected phonation circuit 5 respectively, and circuits for triggering 6 wireless receiving circuits 7 are with thinking that these parts provide power supply; Wireless receiving circuit 7 is electrically connected on-off circuit 8, and on-off circuit 8 is electrically connected between circuits for triggering 6 and/or phonation circuit and the power supply 9, and circuits for triggering 6 are electrically connected phonation circuit 5.

Wherein, wireless receiving circuit 7 can be the module based on wireless communication protocol of any standard, as the wireless receiving module of 2.4GHz.It can pass through antenna, is preferably built-in aerial and receives and identifies outside setting up defences, separate anti-signal and produce output signal accordingly.

The on-off circuit 8 of deploying troops on garrison duty can be a controlled switch, and the control end of this controlled switch is electrically connected an output of wireless receiving circuit 7..Thereby realize being controlled by the output of wireless receiving circuit 7 folding of the on-off circuit 8 of deploying troops on garrison duty, further control triggering electric circuit must dead electricity.Controlled switch can be more than one, such as, controlled switch also is set between phonation circuit and power supply, like this, can further realize economize on electricity.
