Door lock with automatic inductive switch
The invention discloses a door lock with an automatic inductive switch. The door lock consists of a storage battery, the switch, a first resistor, a second resistor, a third resistor, a first triode,a second triode, a third triode, a first diode, a second diode, a first potentiometer, a second potentiometer, a light emitting diode, a photosensitive triode, an operational amplifier, a relay coil,a magnetic lever, a reset spring and a door pull bolt. Compared with the prior art, a positive feedback photosensitive circuit is composed of the light-emitting diodes and the photosensitive triode, when smoke and dust in the environment are sharply increased, the air transparency is reduced, the luminous flux of the photosensitive triode is reduced, the resistance value of the photosensitive triode is increased, the loop current is reduced, the first triode is cut off, and the second triode is conducted, the operational amplifier outputs a signal to enable the relay coil to be electrified togenerate attraction, and the magnetic lever acts, then the door pull bolt is driven to act, further, a lock head is driven to be separated from the door frame, so that the door lock is opened in time,security efficiency is improved, and application and popularization value is achieved.
本发明公开了一种自动感应开关的门锁，由蓄电池、开关、第一电阻至第三电阻、第一三极管至第三三极管、第一二极管、第二二极管、第一电位器、第二电位器、发光二极管、光敏三极管、运算放大器、继电器线圈、磁吸杠杆、复位弹簧和门拉栓组成，与现有技术相比，本发明由发光二极管和光敏三极管组成正反馈感光电路，当环境里烟雾和粉尘急剧增加时，空气透明度变小，光敏三极管的光通量减小，其阻值增大，回路电流减小，使第一三极管截止，第二三极管导通，运算放大器输出信号使继电器线圈得电产生吸引力，磁吸杠杆动作，带动门拉栓动作，进而带动锁头脱离门框，从而及时打开门锁，提高安防效率，具有推广应用的价值。
