Abstract
A dual-function anti-theft alarm lock is composed of lock shell, lock bolt, lock core, buzzer and battery, and features that a shift fork is clamped to the brake rod, another end of shift fork is clamped to the brake pin, which is clamped to the step of lock bolt base plate, and the angle of shift on the brake rod and the contact of reed riveted to insulating plate constitute two contact sets. After the lock is installed, when the door frame is prized or hammered to make the distance of the brake rod head change exceed 1.5-4.5 mm, the circuit can be automatically switched on to alarm, the lock can be conveniently and automatically locked without a key, and the lock tongue can be self-protected by the operation of the key.
Description
A kind of difunctional anti-theft alarm lock, it is applicable to that the security door installation is with locking.
Important departments such as general important office, storehouse, secret chamber have all been installed safe-guard door lock.The more abundant family of some economy has also installed safe-guard door lock in succession recently, but existing safe-guard door lock all needs to stir dead bolt with key, and door lock is lived, and is very inconvenient, have the dead bolt of being dialled in the lock box not have self protective function again, it is not ideal enough therefore to prevent pounding its safety at pick-proof.
The purpose of this utility model is to propose a kind of difunctional anti-theft alarm lock, it can key operatedly spring into dead bolt in the lock box automatically, and can the dead bolt self-insurance not prized again with key operated, thereby it has overcome existing theftproof lock, lacks the defective to above-mentioned two kinds of functions.
The utility model is realized in the following way, it is provided with dead bolt in lock housing 1, the dead bolt substrate, brake bar, the abnormity torsion spring, lock core, buzzer, battery etc., its structure as shown in Figure 1, it is by brake bar 3, insulating slab 12, abnormity torsion spring 5, dead bolt substrate 26 and lock core 24 are formed an arrestment mechanism, wherein be installed with one on brake bar 3 centre positions and dial justice 7, dialling adopted 7 other ends is stuck on the braking tip 6, braking tip lower end is stuck on the step 30 of dead bolt substrate 26, the brake bar bottom righthand side is shaped on stirs pin 8 and 9, on insulating slab 12 and two stir and be shaped on moving together contact group 13 between the pin, 14 and by locking plate 17, the contact sets 15 that contact 16 is formed, 16.Lock on the lock core 24 is dialled in the teeth groove 21 that angle 23 is stuck in dead bolt substrate 26, is fixed on the special-shaped torsion spring 5 on the lock housing, is pressed in by on the boss 27 between dead bolt 1 and the dead bolt substrate 26. Contact sets 13,14 adjusted to when connecting when stirring pin 9 and move forward with brake bar 3 when being higher than outside fixed head 2 planes 4.5 millimeters when dead bolt enters lock box back contact group 15,16, compressing contact 13 and the 14 closed circuit of connecting, buzzer 18 is reported to the police, move to backward when exceeding fixed head 2 planes outsides with brake bar when stirring pin 8 less than 1.5 millimeters, compressing contact 13, the 14 closed buzzer warnings of connecting, and outside brake bar 3 is higher than fixed head 2 planes 1.5 millimeters between 4.5 millimeters the time, contact sets 13,14 is disconnected and is off state.
The utility model has the advantages that:
1, at closing time behind the doorframe collision brake bar tongue just eject automatically and enter lock box, needn't be with the key dead bolt of back-outing.
2, available key rotation lock core makes the dead bolt self-insurance promptly need not be key operated, and dead bolt can not withdraw from lock box, has increased the safety factor of lock.
3, this lock is installed in the middle of the doorframe, and it is can't demolition and being prized when pounding of destruction that door is not opened, make the automatic pole displacement surpass 1.5 to 4.5 millimeters between the time, this lock is promptly reported to the police.
The explanation of accompanying drawing drawing:
Accompanying drawing 1 is difunctional burglar alarm lock construction sectional view
Accompanying drawing 2 is difunctional anti-theft alarm lock electrical schematic diagram
1 is dead bolt, 2 is fixed head, 3 is brake bar, 4 is chute, 5 is special-shaped torsion spring, 6 are the braking tip, 7 for dialling justice, 8 for stirring pin, 9 for stirring pin, 10 is stage clip, 11 is lock housing, 12 is insulating slab, 13 is the contact, 14 is the contact, 15 is the contact, 16 is the contact, 17 is locking plate, 18 is buzzer, 19 is battery, 20 is teeth groove, 21 is teeth groove, 22 are lock group angle, 23 are lock group angle, 24 is lock core, 25 is key, 26 is the dead bolt substrate, 27 is projection, 28 is axle, 29 is block, 30 is step.
Below by embodiment and accompanying drawing the utility model is described further:
This difunctional anti-theft alarm lock is designed to as shown in Figure 1 structure lock housing 11 and is designed to the rectangular box front end fixed pole 2 is arranged, be shaped on 28 and 2 blocks 29 of axle that dead bolt is slided in the centre in the middle of the lock housing, 1 riveting of copper lock housing is on dead bolt substrate 26, form a step 30 between them, dead bolt substrate 26 lower ends are shaped on two teeth groove 20,21, be shaped on lock core 24 on the lock housing of dead bolt substrate below, right-hand buzzer 18 and the solid state battery 19 of being equipped with, the lock housing upper end is shaped on the brake bar 3 that can slide that two bands are stirred pin 8 and 9 in two chutes 4, expose in fixed head 2 sliding eyes on its top, tail end is equipped with stage clip 10, on the lock housing between brake bar 3 and the dead bolt substrate, be shaped on the special-shaped torsion spring 5 and the braking tip 6, the two ends of dialling justice 7 are stuck between the braking tip 6 and the brake bar 3, stir pin 8 insulating slab 12 and two, between 9 by having contact 13,14 moving together contact group and by contact-carrying 15,16 moving together contact group is by the locking plate 17 of riveting on dead bolt substrate 26, another of compressing contact reed 15 and 16 closed formation is to the moving together contact group, contact sets 13,14 are adjusted to when stirring pin 9 and move forward with brake bar 3 and be higher than fixed head 2, during 4.5 millimeters of plane outsides, compressing contact 13 and the 14 closed circuit of connecting are reported to the police buzzer 18; Move to backward when exceeding fixed head 2 planes outside height less than 1.5 millimeters with brake bar when stirring pin 8, compressing contact 13, the 14 closed circuit buzzers 18 of connecting are also reported to the police.All the other other parts become this lock by accompanying drawing 1 assembling, and its circuit theory is referring to accompanying drawing 2.As can be with key 25 with 240 ° of lock core 24 counter-rotatings when making the dead bolt self-insurance, the lock of band gradient on the lock core is dialled in the teeth groove 20 that angle 22 enters band inclined-plane on the dead bolt substrate 26, and withstood the dead bolt substrate, make it make dead bolt carry out self-insurance by withdrawing from the lock box.
