Abstract
The utility model relates to a theft-proof puzzle lock with an alarm for bicycles, which is additionally provided with the alarm, a puzzle switch which can be separated from a bicycle lock, a battery box, a press plate which is used for pressing a locking ring and is arranged on a shifting fork in a locking head, and a microswitch based on an existing bicycle lock. After the warning is set by a key of a puzzle switch and the puzzle switch is pulled out, the bicycle lock can send out alarm sounds to cause a thief to escape for panic to achieve the purpose of theft prevention when the thief uses keys to open the lock, pries the lock, smashes the lock, or dismantles batteries. The utility model is used for bicycles which need to be locked.
Description
The utility model is a kind of anti-theft cipher warning lock, the various lock of existing each shape, all be the limit in from strengthening intensity or improving structure and single warning device reaches antitheft purpose, its shortcoming is the time that makes the car stealer must use heavier instrument or prolongation to destroy lock, still fails the antitheft problem of fine solution.
The purpose of this utility model is the technical scheme that proposes for addressing the above problem, and it is on the basis of existing lock, sets up alarm, battery case and the cipher switch that can separate with lock is formed.Be characterized in when the lock locking and with cipher switch cloth alert break away from lock after, auto theft person no matter with key be unblank, the instrument picking lock, when pounding lock or dismounting battery, this lock all can send chimes of doom, and auto theft person is run away in alarm, reaches antitheft purpose.
(embodiment) is further described below below in conjunction with accompanying drawing:
Fig. 1 is a crypto-alarm lock schematic diagram;
Fig. 2 is cipher switch and alarm logical circuitry;
Fig. 3 is a lock body blocking structure chart;
Fig. 4 is battery case and lock mouth partial cutaway diagrammatic sketch;
Fig. 5 alarm partial cutaway diagrammatic sketch.
(1) crypto-alarm lock among the figure, (2) battery case enclosing cover, (3) alarm, (4) socket, (5) plug, (6) cipher switch, (7) password key, (8) lock core, (9) lock body, (10) lock ring, (11) lock bow, (12) wrench, (13) lock housing, (14) battery case, (15) clamp, (16) pressing plate, (17) shift fork, (18) spring, (19) tapered end, (20) projection, (21) microswitch seesaw, (22) microswitch, (23) battery, (24) battery case inner cap, (25) screw, (26) screw, (27) reed, (28) contact rivet, (29) lock mouth, (30) spring, (31) disk, (32) circular hole, (33) sound transmission aperture, (34) piezoelectric ceramic piece, (35) circuit board, (36) (37) microswitch contact.
As shown in Figure 1: crypto-alarm lock (1) is made of lock body (9), lock bow (11), alarm (3), battery case (14), cipher switch parts such as (6).Cipher switch (6) be provided with plug (5) can with socket (4) on the alarm (3) in conjunction with or separate, separable purpose is: cipher switch (6) can be carried by the car owner, prevents that password key (7) from being destroyed by the people and strengthen the confidentiality of unblanking.
When cipher switch (6) is inserted socket (4), then be unified into logic circuit as shown in Figure 2, this circuit is by 2 R
5Trigger, four d type flip flops and two multivibrators are formed.Its principle is: press A
6～A
8Any button is that cloth is alert in (being password key (7)), and four d type flip flops are all by zero setting; Be Q
1, Q
2, Q
3, Q
4Be electronegative potential, Q
4Be high potential, this moment is (being that battery case enclosing cover (2) is pried open, taken apart or lock is opened, pries open, broken with key and touches microswitch (6)) as long as any one contact in two contacts (36) (37) disconnects in reed (27) and rivet contact (28) among Fig. 4 or the microswitch (22) among Fig. 4, the P point just is that high potential, M point also are high potential, the oscillating circuit work of back, piezoelectric ceramic piece (34) sends chimes of doom.If press A successively
1To A
5(the promptly anti-alert or police that disappears), then Q
4Be high potential, Q
4Be electronegative potential, the m point is an electronegative potential, and oscillating circuit is not worked, and piezoelectric ceramic piece (34) is sounding not.Carry out permutation and combination with 8 different digital buttons, can obtain 6720 groups of passwords, can form the lock of 6720 kinds of different passwords.
Fig. 3 is a lock body blocking structure chart, and shift fork (17) is fixed on the lock core (8), can rotate with lock core (8).Spring (18) one ends are hung on the lock housing (13), the other end is hung on shift fork (17) limit, bottom right, make the pulling force that clockwise direction rotates to shift fork, thereby make the clamp (15) of shift fork (17) be stuck in the indentation, there of lock ring (10), its effect is to make lock keep blocking.The projection (20) of shift fork (17) is pressed on the seesaw (21) of microswitch (22), and its effect is interior (36) (37) of (or shutting) disconnection (or connection) microswitch (22) contact of unblanking.The end of shift fork (17) is provided with pressing plate (16), pushes down lock ring (10), is difficult to pry open lock ring (10) after can making the car stealer pry open the lock base plate.Lock core (8) removable mounting is in tapered end (19) hole.Be provided with wrench (12) as Fig. 4 lock ring (10), lock Che Shike presses wrench (12).One end of spring (30) is hung on lock mouth (29) and locates, and the other end is hung on the end of lock ring (10), and its effect is when unblanking, and lock ring (10) is withdrawed from the retraction lock bow (11) from lock mouth (29) automatically.
Be loaded in the battery case (14) as (23) four on battery among Fig. 4, battery case inner cap (24) is fixed on the battery case (14) with screw (25), battery case enclosing cover (2) adopts the both sides chute to combine with battery case (14), when battery case enclosing cover (2) when pushing, its end compressing reed (27) contacts (being circuit among Fig. 2 (27), (28) contact UNICOM) with contact rivet (28), its effect is when the car stealer takes the battery case enclosing cover apart, reed (27) breaks away from contact rivet (28), and the alert device of plate promptly can send chimes of doom.The sound channel of alarm among Fig. 5 (3) is the semicircle sphere, its side is provided with several sound transmission aperture (33), effect can also be gone into to soak by the rainproof rainwater except that transaudient, and can prevent inserting piezoelectric ceramic piece (34) and the circuit board (35) that destroys the inside from this hole with iron wire.Disk (31) and have circular hole (32), piezoelectric ceramic piece (34) and alarm (3) shell (herein for cylinder) to form the sound chamber of alarm.
This lock is on the basis of general lock, set up cipher switch, the alarm that can separate, be equipped with battery case with lock, shift fork in lock body is set up pressing plate and is pressed position lock ring and projection to push down microswitch, it is alert that this is locked in the button cloth of cipher switch, after transfering to cipher switch, the car stealer with key unblank, picking lock, when pounding lock and removing battery, this lock all can send chimes of doom, the car stealer is run away in alarm, reach antitheft purpose.The car tool that this lock is adapted to lock uses.
