One slide 5, this slide 5 is by being attached on housing 1 dividing plate 12, this slide 5 is towards the relative dividing plate of housing 1 one sides 12 positions, being provided with a guide groove 52 embeds for dividing plate 12, two nose bars 32 of two pressing pieces 3 can be kept out in the two sides of this slide 5, make two pressing pieces 3 can't move the formation locking, this slide 5 central authorities also are provided with one and wear groove 50, pin 121 on the dividing plate 12 is contained in to be worn in the groove 50, and wear 121 of groove 50 and pins, be gripped with a spring 22, these slide 5 bottom surfaces convex with the wedge 51 of an inlay card in start plate 4 grooves 41;
By above each assembly combination, the utility model theftproof lock is provided with one can form the wiring board 6 that is connected with each number wheels 2, on this wiring board 6 and be provided with a switch guide card group 61, the user can select the cipher switch of arbitrary sets of numbers wheels 2 as alarm buzzer 8 by this switch guide card group 61;
As shown in Figure 5, during theftproof lock locking of the present utility model, each number wheels 2 is gone to errors present, control this moment is taken turns 21 protruding grain 211 and is touched guide card group 60 and breaks away from, projection 400 in 4 perforation 40 of start plate, be resisted against on the outer rim of control wheel 21, these start plate 4 controlled ratch 21 outer rims are replaced to a side shifting, this start plate 4 is moving simultaneously, and start plate 4 top groove 41 inclined-planes 410 ejection slides, 5 wedges 51 make slide 5 be moved upward to the location, this moment, slide 5 two sides were near top side location, and backstop is between 3 liang of nose bars 32 of pressing piece, and two pressing pieces 3 can't be pushed start, makes theftproof lock form locking; Because the number wheels 2 of control alarm buzzer 8 switches rotate simultaneously at digit wheel 20, drive 21 rotations of control wheel, protruding grain 211 on the control wheel 21 is broken away from second guide card 602 that wiring board 6 touches guide card group 60, activate alarm buzzer 8, anyone moves leather trunk 9 with the vibration switch 80 in the start alarm buzzer 8, the alarm song that alarm buzzer can send high-decibel frightens the resistance burglar, the user must not activate alarm buzzer at ordinary times, stir the digit wheel 20 of control alarm buzzer 8 in the time of will of short durationly leaving leather trunk smoothly, can activate alarm buzzer 8 easily, reach early warning burglar-proof result completely, go to correct number position and can remove as long as will control the digit wheel 20 of the number wheels 2 of alarm buzzer 8 when desiring to sound all clear;
Desire is during with the theftproof lock complete opening (as shown in Figure 6), the digit wheel 20 of each number wheels 2 is gone to correct number, the control of each number wheels 2 is taken turns 21 breach 212 and is gone to start plate 4 projections 400 positions, on the control wheel 21 protruding 211 contacts with second guide card 602 of wiring board 6 at this moment, and alarm buzzer 8 cuts out; Slide 5 between theftproof lock two pressing pieces 3 is moved down by spring 50 elastic force starts, and this moment, theftproof lock was opening, and the user can push two pressing pieces 3, makes the lock hook 301 of pressing piece 3 break away from housing 1 caulking groove 110, and leather trunk 9 is opened;
See again shown in Fig. 7 that be the wiring diagram of alarm buzzer, it is described as follows:
(1), when circuit is in closed condition, the combination lock switch is short-circuit condition, so U2 input end grounding output sends high potential and arrive U4 through D2 and R6, therefore can suppress the signal of being brought by vibration switch.
(2), the number lock-switch is open-circuit condition when circuit activates, this moment, R2 and C2 formed delay circuit, postponed for three seconds and just will send the electronegative potential cancellation by U2 to suppress signal, and at this time signal can enter U6 smoothly when vibration switch moves.
(3), after circuit is opened when vibration switch is touched, then signal postponed for three seconds via R1, C1 and R4, C3, just signal is delivered to U3 and activated timing circuit (R2 and C4), this moment, U6 obtained to send next triggering signal generation alarm song to by U4, U5, and by C4 and R5 timing two minutes, alarm song stopped and getting back to the state of alert after two minutes.
(4), the coded lock switch is replied short-circuit condition during shut-off circuit, so the U2 input end grounding, and via the delay circuit that C2 and R3 form, postpones just high potential to be delivered to U4 through D2 and R6, the signal that inhibition is brought by vibration switch in three minutes.
When the number of theftproof lock rotates when correct, switch forms short circuit alarm buzzer this moment and cuts out, if when rotating to incorrect number, switch forms open circuit alarm buzzer this moment and activates, can not touch theftproof lock again after the activation, if theftproof lock is shaken by external force, can open inner vibration switch, alarm buzzer postpones to sound the alarm after three seconds, postponing three seconds main causes is to allow the user, there is the enough time to remove the device of sounding all clear, also must bumps theftproof lock, therefore need to postpone because the user will close alarm buzzer.
After the alarm buzzer action sounds the alarm, three seconds after the alarm buzzer of theftproof lock cuts out, alarm song just can stop, allow the burglar can't learn at once whether the number of its rotation is correct, so increase the degree of difficulty that theftproof lock is unblanked, that is after alarm buzzer action, alarm buzzer cuts out coded lock must be rotated to the tram, and stop and alarm buzzer could cut out for three seconds.
In sum, the utility model is filed an application in accordance with the law, please give approval.
