Description

Multi-functional electronic alarm latch-lock

The utility model relates to a kind of latch, especially a kind of multifunction electronic alarm latch.

What existing market was sold is a kind of latch of typing, and its function singleness only plays the effect of locking a door.When particularly this latch is prized, can not send alarm signal, its theftproof is not strong.

The purpose of this utility model is for by the improvement to existing latch structure, and provide a kind of have report to the police and the latch of doorbell function.

The utility model is by housing, tapered end, circuit for alarming and linked switch are formed, it is characterized in that housing is made up of lid 8 and box body 15, alarming horm is installed on the lid 8, tapered end, circuit for alarming and linked switch are installed in box body 15 inside, linked switch is by interlock push rod 22, nailing 5, nailing pin 27, nailing back-up ring 26, nailing compression spring 43, nailing locking nut 44, circuit breaker 24, power switch 25, power switch negative pole 37, power switch positive pole 38, circuit breaker positive pole 35, circuit breaker negative pole 36 is formed, the end of push rod 22 of wherein linking is fixed on the middle part of the connection mainboard 18 of main dead bolt 4 with screw, one end of nailing 5 penetrates box body inside from the nailing hole 45 of box body 15 sides, nailing pin 27 is inserted in the fixed pin holes of nailing 5, and with nailing back-up ring 26, nailing compression spring 43, be sleeved on the nailing 5, the end of nailing 5 penetrates in the connecting hole of interlock push rod 22 other end sides, and nailing 4 and interlock push rod 22 are connected and fixed with nailing locking nut 44, the switch lever of power switch 25, be pressed together on the bottom head end of interlock push rod 22,

circuit breaker

24 and 44 pressings of nailing locking nut, circuit for alarming is by power switch 25, circuit breaker 24, loudspeaker 6 and tablet are formed, the positive pole 37 and the 6V dc power anode of power switch 25 join, and the negative pole and the tablet of power switch 25 join.

Below in conjunction with accompanying drawing architectural feature of the present utility model is further specified:

Fig. 1 is the lateral view of Fig. 3.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is a structural representation of the present utility model.
