Abstract
An electronic lock tamper-resistant alarm device belongs to the technical field of the door lock, and comprises a micro switch and an alarm control circuit for sending alarm signal when triggering the micro switch, wherein the electronic lock tamper-resistant alarm device is arranged on one side of a lock body panel. The utility model is characterized in that the tamper-resistant alarm device also comprises a tamper-resistant lever and a torsion spring, wherein the tamper-resistant lever is fixed on the lock body panel through the torsion spring, one end of the tamper-resistant lever extends from the lock body panel to prop against the door, and the other end thereof is kept in the distance on which the elastic force of the torsion spring can make the end trigger the micro switch when the lock body panel is separated from the door. The utility model triggers when the micro switch is pressed, avoids the defect that the normally closed switch is easy to fail to work in the prior art, and is also convenient to assemble through the positioning of the tamper-resistant lever by the torsion spring.
Description
Technical field
The utility model belongs to the door lock technical field, and the lock panel that is specifically related to electronic lock is at the Pickproof alarm device that is subjected to can touching when external force prizes (violence is unblanked).
Background technology
The Pickproof alarm device of present commercially available electronic lock by switch, flexible thick stick, spring constitutes, flexible thick stick passes lock panel, and flexible thick stick socket spring is when the integral body lock is installed on the door, flexible thick stick touches switch by the pressure of door and the effect of spring, and this moment, switch was in closure state.When generation external force prized (violence is unblanked), because the lock front panel breaks away from door, the thick stick that stretches broke away from switch under spring action, touches warning circuit, gives the alarm.
Because the switch in the Pickproof alarm device adopts the normally closed switch that possesses pressure sensitive by door the pressure that flexible thick stick is produced to be in off state by normally closed switch basically, this moment, warning circuit can not worked, but in case pry open lock, normally closed switch can be because losing pressure closure, make the warning circuit sounding alarm.The elastic device of microswitch inside is in pressure state for a long time.After the process use of certain hour, aging distortion takes place in microswitch easily, thereby causes the warning device inefficacy.Moreover flexible thick stick is had an effect fitting operation inconvenience after need passing the lock body front panel by revocable spring assembly.
Summary of the invention
The utility model purpose is the defective that easily lost efficacy for the warning device microswitch that solves prior art, and a kind of reasonable in design, switch reliable operation, the simple Pickproof alarm device of assembling are provided.
The technical scheme that its technical problem that solves the utility model adopts is:
Electronic lock Pickproof alarm device, comprise microswitch and when microswitch triggers, send the alarm control circuit of alarm signal, electronic lock Pickproof alarm device is installed on a side of lock panel, it is characterized in that the Pickproof alarm device also has pick-proof lever and torsion spring, the logical torsion spring of pick-proof lever is crossed and is fixed on the lock panel, one end self-locking body panel of pick-proof lever stretches out and leans door, and the elastic force by torsion spring when the other end and microswitch remain on lock panel with the door disengaging can make this end trigger the distance of microswitch.
The utility model electronic lock Pickproof alarm device compared to existing technology, beneficial effect mainly shows when being the microswitch pressurized and triggers, the defective of having avoided the long-term pressurized of prior art normally closed switch easily to lose efficacy, by torsion spring location pick-proof lever, easy to assembly in addition.
Description of drawings
Fig. 1 a is the structural representation under the prior art Pickproof alarm normality.Fig. 1 b pries open the back structural representation for the prior art Pickproof alarm
1 is switch among Fig. 1 a and Fig. 1 b, and 2 are flexible thick stick, and 3 is spring, and 4 is lock panel,
Fig. 2 a is the utility model Pickproof alarm device structural representation under normal conditions.
Fig. 2 b is the structural representation of the utility model Pickproof alarm device after violence is pried open.
Description of symbols among Fig. 2 a and Fig. 2 b: 5 is microswitch, and 6 is torsion spring, and 7 is the pick-proof lever; 8 is Door lock casing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 a and Fig. 1 b have demonstrated the Pickproof alarm device of prior art, and the Pickproof alarm device is by switch 1, and flexible thick stick 2 and spring 3 are formed, and flexible thick stick 2 passes lock panel 4, and flexible thick stick has spring base, bar portion socket spring 3, and under the normality, expansion link 2 roof pressures are in switch 1; When violence is pried open, the elastic force of spring 3 will drive flexible thick stick 2 and throw off switch.
Fig. 2 a and Fig. 2 b, electronic lock Pickproof alarm device of the present utility model, by microswitch 5, torsion spring 6 and pick-proof lever 7 are formed, and wherein pick-proof lever 7 is fixed in Door lock casing 8 by torsion spring 6.
Whole lock is installed in when last, and an end of pick-proof lever 7 is pressed on the door, and an other end is positioned at the microswitch below, by the effect of torsion spring 6, makes pick-proof lever 7 and microswitch 5 keep the 3-5 mm distance.
When prizing (violence is unblanked) when lock panel runs into, face Door lock casing 8 breaks away from the shop front, effect by torsion spring 6, pick-proof lever 7 contacts with microswitch 5 near of microswitches, the triggering microswitch is reported to the police, and promptly microswitch is electrically connected with loudspeaker, makes loudspeaker generation alarm song when microswitch triggers, perhaps the output of microswitch inserts warning system, sends a signal to center control place by built-in communication apparatus.
