Abstract

A double-person unlocking anti-theft electronic puzzle lock consists of a main lock (A) and an auxiliary lock (B), the main lock (A) is arranged on the door and the auxiliary lock (B) is arranged on the wall outside the door with the arrangement distance longer than two meters and longer than an arm of a person. The main lock (A) is controlled by the auxiliary lock (B), only after the circuit of the auxiliary lock (B) is switched, the signal is transmitted to the electromagnetic pickup device in the main lock (A) to achieve the pickup, and the main lock (A) can be unlocked with the key after control is removed; furthermore, the time of unlocking is short and the distance between the main lock (A) and the auxiliary lock (B) is large, thereby truthfully realizing the double-person unlocking anti-theft electronic puzzle lock.

Description

The double electronic puzzle theft-proof lock of opening

The utility model is about coded lock, particularly about the electronic password lock of double unlatching.

In the management of important events, its door is twin-lock, should have only double everyone take one just can enter key unlocking, this is a routine.But this conventional measure exposes a shortcoming that is difficult to overcome in practice, is subjected to artificial factor exactly in practical operation, follows the line of least resistance, dislikes trouble, and often gives a people key and goes to open the door, and too trusts the root that goes wrong often.At present, solving double twin-lock problem technically is the developing direction that solves this type of problem, along with various types of Fingerprint Lock have appearred in the development of technology, satisfy the specific (special) requirements of double twin-lock on the function substantially, but with high content of technology, complex structure, fault is many, price is expensive.Certain conditions being possessed some also arranged about the invention on the double twin-lock, all do not realize double twin-lock truly, as long as all can a people be opened.

The purpose of this utility model is in order to solve the problem on the above-mentioned prior art, and a kind of simple in structure, double electronic puzzle theft-proof lock of opening that cost is low is provided.

Technical solution of the present utility model is made up of main lock (A) and secondary lock (B).It is characterized in that: the mounting distance (C) between main lock (A) and the secondary lock (B) is between 2.5 to 10 meters, and the unlatching of main lock (A), except that with the key operated mechanical lock (1), also be the unlatching of the electromagnetic attracting device (2) in the main lock (A), and electromagnetic attracting device (2) is controlled by mechanical switching circuit (4) in pair lock (B) and password switching circuit (5), (6), (7) and delay circuit (8); In addition, on main lock (A), be provided with electromagnetic force attracting device (2), power supply pulse indicator lamp (3), on pair lock (B), be provided with line under-voltage indicator lamp (9) and power supply (10).

The utility model compared with prior art, realized double unblanking truly, because the mounting distance between main lock (A) and the secondary lock (B) is long above a people's both arms greater than 2 meters, even a people has the mechanical key of main lock (A) and secondary lock (B), also is to unblank.In addition, secondary each effective opening time of locking (B) the main lock of control (A) has only 1.5～2.5 seconds, in the so short time, a people can not run to open main lock (A) after the control of open auxiliary lock (B) again, so the utlity model has simple to operate, cost is low, and is easy for installation, non-double " the double two opening " electronic puzzle theft-proof lock truly that can not open.

Below be to brief description of drawings:

Fig. 1 is the block diagram of technical solution of the present utility model.

Fig. 2 is the structural representation of main lock of the present utility model (A).

Fig. 3 is the external structure schematic diagram of secondary lock of the present utility model (B).

Fig. 4 is control circuit figure of the present utility model.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

In conjunction with the accompanying drawings, the utility model is made up of main lock (A) and secondary lock (B).Main lock (A) is installed on the door, and secondary lock (B) is installed on 2 meters outer walls of the main lock of distance (A), main lock is subjected to secondary lock control, main lock (A) by with common antitheft cross machinery phase-locked with tapered end (1) and electromagnetic force attracting device (2), pulse indicator lamp (3) formed.Under normal lock state, the rear portion block (12) of tapered end (1) is interfered mutually with the anterior block (11) of electromagnetic force attracting device (2), makes tapered end (1) promptly use key mechanical to unblank, because the interference effect of the link stopper (11) of electromagnetic force attracting device (2) can not be unblanked.Only when the Cross lock of the playback certainly control circuit switch (4) of pair lock (B) is opened with secondary lock key always, and the input password is correct, when password circuit breaker (7) is opened, pulse delay circuit (8) time-delay of two like this start signal in pair lock (B) is transferred to the electromagnetic force attracting device (2) of main lock (A), make its adhesive, link stopper (11) retreats, and interferes and removes, and can unblank.

Secondary lock (B) is by power supply (10), and the Cross lock gauge tap (4) that playbacks certainly, line under-voltage indicator lamp (9), 10 password input circuits (5), 2 pulse per second (PPS) delay circuits (8) are formed.Have cipher code storing electric circuit (6) and password update switch (7) at 10 password input circuits (5) built-in.

When pair is locked (B) with after key operated, by connecting rod pair is locked power connection, and must continue to grapple key and could continued power unblank, the people can not let go, purpose is " pinning " first unlocking person, and the secondary lock of unlocking person input this moment proper password, when identical with the circuit preset password, the time-delay output circuit is switched on, only delayed time for 2 seconds, behind the signal that main interlocking is locked to pair, main lock indicator lamp is bright, electromagnetic force attracting device adhesive in the main lock, main this moment lock is available key operated, and the time has only 2 seconds, blackout after 2 seconds, electromagnetic force attracting device dead electricity resets, main lock can not be opened, and the 2 second short time remains for " pinning " first unlocking person, prevent that it from taking other fixation to the cross lock of playbacking certainly after, remove to open main lock (A) again, really realize double purpose of unblanking.

According to the disclosed technical solution of the utility model claims; those skilled in the art make multiple improvement in the protection domain that does not exceed claim be possible; distance as main lock and secondary lock is provided with size, the length of delay circuit delay time, what of password figure place.
