Referring to accompanying drawing, a kind of lamination alert files cupboard, comprise a plurality of joint cupboards, be provided with remote-control burglar alarm in the cupboard, remote-control burglar alarm comprises telepilot 5, receiver 6, alarming horn 7 and power supply 8 and power switch 9, it is characterized in that having trigger switch k1 on the interior edge strip 3 of the cupboard doorframe of upper strata joint cupboard 2, the bottom of upper strata joint cupboard 2 is provided with plug A1, B1, also be provided with drawer 1 in the joint cupboard 2 of upper strata, plate inboard, joint cupboard 2 back, upper strata, trigger switch K2 is equipped with at corresponding drawer 1 place; Have trigger switch K1 on the interior edge strip 3 of the cupboard doorframe of bottom joint cupboard 4, the top of bottom joint cupboard 4 is provided with socket A2, B2 and trigger switch K3, receiver 6, alarming horn 7 and power supply 8 and power switch 9 are equipped with in the bottom of bottom joint cupboard 4, four pin of bottom joint cupboard 4 also are equipped with trigger switch K4, wherein plug A1, B1 join with socket A2, B2 are corresponding, and trigger switch K1～K4 is connected by plug A1, B1 and socket A2, B2 are parallel; The socket B2 of bottom joint cupboard 4 connects power cathode, and the socket A2 of bottom joint cupboard 4 joins warning water chestnut carboxylic 7 another termination power switches 9 through relay J 1 contact and the alarming horn 7 of receiver 6.

See Fig. 6, have trigger switch k1 on the interior edge strip 3 of the cupboard doorframe of the joint cupboard 10 in the middle of being placed on, socket A2, B2 and trigger switch K3 are equipped with in top, and plug A1, B1 are equipped with in the bottom.

Lamination warning retaining case cupboard can be formed with two～four joint cupboards.

Trigger switch K3 is equipped with in about joint cupboard top or front and back, also can on joint four corners, cupboard top trigger switch K3 be housed.

See Fig. 6, in an embodiment, all can be provided with drawer 1 in each joint cupboard and reach plate inboard behind the joint cupboard that trigger switch K2 is equipped with at corresponding drawer 1 place.Side at bottom joint cupboard 4 is provided with power output socket 11 in addition.

Remote-control burglar alarm, adopt the circuit in the light burglar alarm safety cabinet, referring to Fig. 3, Fig. 4, remote-control burglar alarm comprises telepilot 5, receiver 6, power supply 8, power switch 9 and alarming horn 7, telepilot comprise scrambler and self-excited oscillator wherein scrambler form by coding integrated package IC1 and timing resistor R2, self-excited oscillator is made up of BG1, L1, C1, C2, C3, R3, R4.Telepilot also is provided with a self-lock switch K, the termination power positive pole of self-lock switch K, and the other end of self-lock switch K also connects voltage stabilizing diode WD and LED, and another termination coded set of WD becomes 18 pin of piece, another termination power cathode of LED.Receiver comprises Armstrong circuit, amplification and rectification circuit, demoder, phase inverter and pilot relay J1, and the contact of pilot relay J1 is serially connected between trigger switch and the alarming horn 7; In fact Armstrong circuit gets the receiving unit of superregenerative receiver, and it is made up of R5～R7, C7～C12, D1, L2, L3 and BG2, and receive frequency is determined by L3, C7.The coded signal that demodulates is coupled to the amplifier shaping circuit through C13.Amplification and rectification circuit is made up of R10～R12, C14～C16, BG3 and IC3, and IC3 is the operational amplifier integrated package, plays shaping operation at this.Coded signal is delivered to 14 pin of decoding integrated package control end IC2 after BG3 amplification, IC3 shaping.At this moment, if signal is identical with the demoder coding, then 17 pin of IC2 are exported high level.The output terminal of IC2 is connected with phase inverter input resistance R14 through diode D2.Phase inverter is made up of R14, D3, C11 and BG4, and relay J 1 is the phase inverter load.When pressing self-lock switch K, telepilot work this moment, send a modulated carriers signal, receiver is received this modulated carriers signal through amplifying shaping, if this demoder IC2 decoding is identical with scrambler IC1 coding, then IC2 output terminal 17 pin are high level, make the BG4 conducting, relay J 1 adhesive, relay J 1 contact goes to control being switched on or switched off of remote-control burglar alarm, promptly connects and reports to the police or the releasing warning.
