Description

The rolling door anti-prying alarm lock

The utility model is a kind of lockset of rolling door Pickproof alarm.Be to be used to prevent rolling door,, remove storekeeper's trouble and worry for the storekeeper has built a management environment that safety is relieved by the generation of the incident of prizing.

The producer of domestic production rolling screen door lock is a lot of at present, " Heng Feng " and " mountain " serial rolling screen door lock as the production of Guangdong Province Hengfeng Lock Co., Ltd., Panyu City, " thousand sail boards " rolling screen door lock that the South Sea, Guangdong Province city red flag metal product plant is produced, " universe board " rolling screen door lock that Danyang City, Jiangsu Province second Lock Factory produces, and the rolling screen door lock of these manufacturer production all can not effectively be reported to the police when the robber prizes or pries open rolling door, will make the storekeeper suffer enormous economic loss, and threaten watchman's life safety.

The purpose of this utility model is to make rolling screen door lock have the triggering warning function.

Rolling door anti-prying alarm lock of the present utility model is by lock body, trigger alarm mechanism, alarm or alarm signal transmitter constitute, the triggering alarm mechanism is fixed on the back of lock body, alarm or alarm signal transmitter are fixed on and trigger on the alarm mechanism, lock body is by common rolling screen door lock, the fixing microswitch in lock inside lock lever below constitutes, trigger alarm mechanism by framework, protection tube, top guide bar, the protection spring, interior contact stem, plectrum, the warning spring, microswitch, formations such as regulating sleeve, the bottom of protection tube passes the hole under framework, the protection spring is installed between the top and framework of protection tube, top guide bar passes the top that hole on the framework and protection spring are fixed on protection tube, microswitch is fixed on the top of protection tube, protection tube, microswitch, top guide bar is fixing in aggregates, can under the protection spring action, move up and down, regulating sleeve is installed in and passes on the outer top guide bar of framework, interior contact stem is passed the bottom of protection tube, plectrum is fixed on the head of the interior contact stem in the top of protection tube, the warning spring is installed on the top of the upper surface of plectrum and protection tube between the inner face, when the bottom of interior contact stem and protection tube flattens, plectrum is pushed down microswitch, in decontroling during contact stem, under the warning spring action, interior contact stem will be stretched out from the bottom of protection tube, and plectrum separates with microswitch simultaneously.

The utility model rolling door anti-prying alarm lock has been compared following characteristics with traditional roller shutter door alarm device: at first traditional roller shutter door alarm device, lock separates with warning device, warning device generally adopts vibration and special-purpose rolling door magnetic to report to the police, have cost height, false alarm, inconvenient, the also wiring in addition of installation easily, setting up defences needs to use Digiplex, after the need that open the door be set up defences with the remote controller releasing, turn the key in the lock again.And the rolling door anti-prying alarm lock is formed one by common rolling screen door lock, triggering alarm mechanism, alarm (transmitter), installation is identical with common rolling screen door lock, does not need other wiring and boring, has easy for installation, and can exchange with common rolling screen door lock, the lockset cost is low.When the storekeeper triggers alarm mechanism when closing rolling door and promptly sets up defences automatically leaving behind, do not need unnecessary action.Trigger alarm mechanism reliability height, protection tube is under the effect of protection spring, can effective closure do not destroyed by the robber with the interior contact stem of protection, false alarm can not appear, but warning sensitivity free adjustment, when rolling door is not also pried open, alarm sends sharp-pointed chimes of doom at once, can deter the robber, and remind and to keep people from shop and in time take the precautionary measures, if what install is the telephone automatic alarm main frame, after receiving the wireless alarm signal that the rolling door anti-prying alarm lock sends, main frame meeting Automatic Cycle when sending chimes of doom is transferred to the owner's who has stored phone, mobile phone, the phone at call or security personnel center makes owner obtain stolen information.

Be illustrated in conjunction with the embodiments with reference to the accompanying drawings below.
