Abstract

The utility model relates to a closed contactless remote-controlled lock protector, which uses radio service code control circuit technique with high reliability and repetition rate which is lower than 0.0003 percent in a lock protector. A closed electromechanical combined steel base 1 is installed and covered on the outdoor part of a lock, when a hand held service code remote-controlled circuit transmitter is started, a matched service code receiving device changes electric pulse signals into mechanical pulse signals, causing a small steel door 2 to be automatically opened, to expose an original keyhole, and then the lock is opened by a metal key. The protector has the characteristic that the utility model has seal property, firmness, no external contact, remote control and convenient operation, has an alarm, can transmit alarm signals, etc. The utility model is used for protecting a traditional lock from being functionally intruded or destructively intruded, and consequently, improves the security of the lock.

Description

Sealed contactless remote control Lock protector

The utility model relates to a kind of sealed contactless remote control Lock protector.

Lock is a kind of device that is used to take precautions against various intrusion.At present, the overwhelming majority is used to security door, Hu Men, warehouse door and office door etc., all is with the switch of metal key as lock, has continued to use decades.In recent years, in some four stars with good conditionsi, five-star hotel has been installed magnetic card lock, and the key of this lock is a magnetic card.In view of many reasons, this magnetic card lock only is used for the room in luxurious hotel's environment at present.It is a kind of lock that is used in various safety cabinets at present also that external contact formula mechanical code lock and digital and electronic lock is arranged in addition, but the operator must keep password firmly in mind, is not easy to operation.Because magnetic card lock, mechanical code lock and digital and electronic lock are subjected to the restriction of environment and operability, therefore are difficult to use on vast outdoor strick precaution occasion.So, have only mechanical lock widely to popularize at present.

In recent years, the structure of mechanical lock and key is improved gradually, and its strick precaution ability day by day improves.But because its structure belongs to mechanical type, external contact is arranged, so its raising of taking precautions against degree is subjected to its mechanical circumscribed restriction.These limitation have constituted not only can be subjected to the worried and trouble that causes because of the destruction on the function, more can suffer the pernicious attack of burglary.So traditional mechanical lock has been subjected to challenge aspect Secure Application.

The worry that can't normally unblank that the utility model device not only can protection lock brings to prevent the destruction on any function; the more important thing is has increased sealed no external contact together, wireless remotecontrol, the antitheft and firm steel body protective device of reporting to the police; and, easy operating.

Below in conjunction with accompanying drawing and concrete operating principle, the utility model is elaborated:

Fig. 1 is sealed contactless dynamo-electric combination steel pedestal.

Fig. 2 is the rear elevation of Fig. 1.

Fig. 3 is a cipher remote control circuit transmitter.

Fig. 4 is that the cipher remote control circuit receives controller.

Fig. 5 is this device scheme of installation.

The utility model is made up of three parts: the dynamo-electric combination of closed contactless steel pedestal, cipher remote control circuit transmitter and password Remote control circuit receives controller. Socket 25 links to each other with interface 10, by lead 24, carries out the signal of telecommunication between Fig. 2 and Fig. 4 Transmission. The family that the dynamo-electric combination of closed contactless in the utility model steel pedestal 1 is installed on door by an exterior door shown in Figure 5 Outer part covers lock, and little steel casement door 2 covers the keyhole position, when little steel casement door 2 is opened, can expose keyhole, in order to open the lock with the key. The cipher remote control circuit receives controller 18 and can be positioned in the door or position in the door.

Fig. 3 is cipher remote control circuit transmitter, adopts high reliability radio cipher remote control circuit, and its multiplicity that transmits is little In 300,000/. When preparing to open the door, at first hand-held remote controller 14 pushes button 15, namely produces on the printed circuit board in the button box Give birth to signal and by microstrip antenna 17 to air-launched, indicator lamp 16 is luminous simultaneously, effectively transmitting range is tens meters, with it The controller 18 of joining receives the cipher remote control signal by microstrip antenna 19. So controller produces the pulse command signal of telecommunication, by Interface 23 is through lead 24, and socket 25 and interface 10 are passed to electromagnet 4, and electromagnet 4 energisings produce suction, the little steel of adhesive Door bolt 5, away from little steel casement door back gate slot 8, little steel casement door 2 is opened automatically by turning cylinder 3 under the effect of spring 9, Flow through after the electric impulse signal of electromagnet 4, electromagnet 4 suction disappear, and under the effect of spring 6, little steel door bolt 5 is answered back Original position. Afterwards open mechanical lock with door key by the little steel casement door 2 of opening, open the door and extract key, close little steel casement door 2 with hand and advance Enter indoor. Namely only need to start the remote controller 14 in the hand, little steel casement door 2 will be opened automatically, exposes keyhole, opens door by key, Close again little steel casement door.

Since the utility model adopted high reliability, repeatability less than 300,000/ radio cipher remote control circuit, and the external structure of protection lock and keyhole is the steel seat of sealing, open little steel casement door also for non-external contact formula, eliminated non-tight and trouble and worry that contact caused; Repeatability less than 300,000/ radio cipher remote control match circuit, this means, one group of identical cipher remote control circuit transmitter, can only make the cipher remote control circuit that matches receive controller starts, he can accomplish to compile 300,000 passwords and not repeat, thereby increased the safety of remote control part, especially for the invador, any attempt is to the destruction of this lock, all can produce improper vibration, thereby cause Fig. 2 shock sensor 12 to produce signal, reach Fig. 4 controller 18, and startup alarming horn 21 is rung by lead 24.If the outer signal monitoring system is arranged, Fig. 4 socket 22 is also reserved this signal output socket.

When cell voltage is low when maybe needing to change, the 20 luminous promptings of Fig. 4 indicator lamp.Fig. 2 socket 13 is the external connection battery socket, just in case can be with this socket from the externally fed energy when the battery cisco unity malfunction.

Described as precedent, after door lock has been installed the utility model device, avoided causing and can not unblanking owing to non-tight suffers the destruction on the function.Especially to no-knock burglar and various forcible entry, no matter use which kind of method, desire is opened protected lock, at first Gonna breakthrough protection of the present utility model.Yet any attempt illegally enters, and under not to the remote controller situation that should install, can only carry out violence nature to this lock to destroy, iron is bulky such as using, crowbar and electric drill etc., all can produce improper vibration, thereby cause the alarming horn of the utility model device to be rung.In like manner, the destruction of opposite house also can cause the alarming horn of this device to be rung.

Except that Fig. 1 to the shape and installation site shown in Figure 5, the utility model other shapes, structure, installation distortion can also be arranged or with the lock design as a whole and adopted repeatability less than 300,000/ radio cipher remote control technology, its operating principle and preventing function all roughly the same and not depart from the scope of the present invention.For example, Fig. 1 profile can be other geometries also, and as semicircle, that is protected also is not limited only to mechanical lock and keyhole, can be mechanical switch, outside contact-type electronic coded lock or plug-in type magnetic card lock.
