Abstract
The utility model discloses a kind of lock core induction alarm equipment, comprise housing and core body; Described core body comprises copper sheet, power supply, chip, electric bell, wire, contact chip, pin, fore-set and fore-set spring; By wire copper sheet, power supply, chip, and contact chip is together in series, chip controls electric bell; Do not pull out after 5 seconds when key inserts lock core, so now pin will be upspring and is with moving contacting plate to contact with copper sheet, and make circuit form path, electric bell is sounded, and plays warning function.
Description
Technical field
The utility model relates to anti-theft tool, is specifically a kind of lock core induction alarm equipment.
Background technology
According to investigations, many families are stolen is forgotten behind the door to pull up key and the chance that provides burglary to thief because owner opens (pass), causes no small loss to family.This all comes from our carelessness, if there is the lock core reminding owner to take off key just can avoid the generation that this kind of thing.Therefore, in order to the utility model that solves the problem provides lock core induction alarm equipment, when after owner opens the door, key stops lock core 5 seconds, the prompting owner that will sound takes off key, it is low that the utility model has cost, practical, applied widely, the advantages such as structure is simple, easy manufacture.
Utility model content
The purpose of this utility model is to provide a kind of lock core induction alarm equipment at this, to be upspring band moving contacting plate, contact chip is contacted with copper sheet, the path of completing circuit by pin, and chip controls electric bell is sounded prompting owner; Structure is simple, and principle is simple.
The utility model is achieved in that a kind of lock core induction alarm equipment of structure, comprises housing and core body: it is characterized in that: described core body comprises copper sheet, power supply, chip, electric bell, wire, pin, contact chip, fore-set and fore-set spring; Fore-set is connected with fore-set spring, and is positioned at lock core centre position; Pin is positioned at lock core innermost end position.
According to lock core induction alarm equipment described in the utility model, it is characterized in that: by wire by copper sheet, power supply, chip and contact chip are together in series; Electric bell is connected with chip by wire; Chip controls electric bell.
According to lock core induction alarm equipment described in the utility model, it is characterized in that: described contact chip is positioned in the middle of copper sheet and pin, copper sheet is positioned at top, and pin is positioned at below.
Lock core induction alarm equipment described in the utility model, after improving, comprises core body and housing; Described core body comprises copper sheet, power supply, chip, electric bell, wire, contact chip, pin, fore-set and fore-set spring; By wire copper sheet, power supply, chip and contact chip are together in series, and chip and electric bell are linked together by wire.Fore-set and fore-set spring are positioned at lock core centre position, and pin is positioned at the most inner position of lock core, and contact chip is positioned in the middle of copper sheet and pin, and copper sheet is positioned at top.When key after owner opens the door is stayed after lock core reaches second, pin is upspring automatically, and band moving contacting plate moves and contact chip is contacted with copper sheet, and make circuit formation path, chip controls electric bell is sounded, and points out owner to take off key.
The utility model tool has the following advantages:
