Abstract

The utility model relates to an intelligent magnetic-power lock for doors. The utility model is composed of a lock body and a relay iron plate. The lock body (1) and the relay iron plate (4) are respectively provided with one suit or two suits of probe mechanisms and memory wafer mechanisms. When a probe (12) touches a memory wafer, the utility model alarms the state of a door. The utility model has the advantages of convenient assembly, convenient disassembly and convenient maintenance, and can be interchanged with a common magnetic-power lock.

Description

Intelligent magnetic door lock

The utility model relates to a kind of intelligent magnetic door lock, relates in particular to the intelligent magnetic door lock in places such as being widely used in hotel, airport, secret office, museum, bank, military key area.

The patent No. is that ZL93225436.5's " safe magnetic door lock " disclosed technical scheme is, as Fig. 4, shown in Figure 5, Electromagnetic lock 5 one or both sides that are installed on the doorframe have 50, CPU for anodal and security control chamber of two exploring electrodes to join another root ground connection respectively; The iron plate 6 of continuing is installed on the door leaf, is provided with memory wafer circuit board 61 with the iron plate 6 of continuing of the one or both sides of two exploring electrode 50 correspondence positions, and there are two sensing points 60 in the front of circuit board 61, and it has a memory wafer 62 to be connected with two sensing points 60 behind;

When door leaf was in closed condition, exploring electrode 50 contacted with sensing point 60, after the CPU of security control chamber reads correct sequence number on the memory wafer 62, just determined and show gate is in off status.

These innovation and creation have overcome the unsafe disadvantage of general magnetic door lock by memory wafer, but the structure of exploring electrode and memory wafer circuit board is installed, need design again the Electromagnetic lock of common magnetic door lock and the iron plate of continuing, thereby both can not be general, increased cost; Exploring electrode and memory wafer circuit board are arranged on one or both sides, so tolerance is little, but move left and right is only installed inconvenience.

The purpose of this utility model is to overcome above-mentioned existing problems, and a kind of have standardized memory wafer and sonde configuration, its intelligent magnetic door lock that mounting or dismounting are convenient, interchangeability is strong are provided.

The utility model is to realize like this.

The utility model reaches corresponding the continuing iron plate composition on the door leaf that be installed in it by the lock body that is installed on the doorframe, distinguish the probe and the memory wafer structure of signalization output at the center position of the lock body and the iron plate of continuing, sonde configuration and memory wafer structure are the independent standard parts, when the user need adopt memory wafer to differentiate magnetic door lock state of living in, then install sonde configuration and memory wafer structure; If the user does not want the more expensive memory wafer structure of price, just memory wafer is replaced by conducting strip, in its energising or when outage,, probe is with after conducting strip contacts, and can occur closing or open mode; Sonde configuration and memory wafer structure just can be used as general magnetic door lock if dismantle.

The utility model has the advantages that:

1. owing to adopted the lock body of standard and the iron plate of continuing, the center is installed or sonde configuration and memory wafer structure is not installed, and it is interchangeable with general magnetic force lock body to reach intelligent door lock, reduces cost, and has improved practicality;

2. be in the iron plate center memory wafer that continues and not only have security reliability antimagnetic, anticorrosion, anti-electrical interference, and have 64 a powers frequency number of 2,, reach a lock one usefulness, strong security with this switch element as lock;

3. probe is the bigger plate-like of scope with memory wafer and contact, the iron plate of the continuing center 360 degree rotations of can having mercy on, and probe still can accurately be differentiated the state of door, therefore gives to process and adjustment brings convenience.

Below in conjunction with drawings and Examples the utility model is described further.
