Description

Code electromalgnetic lock

The utility model relates to a kind of coding lock, the especially code electromalgnetic lock that can open automatically.

The coding lock is a kind of blocking device that prevents maloperation that electric power system is installed, existing coding lock mostly is mechanical coding lock greatly, this coding lock adopts the mechanical contact coding, it is unreliable to work, adopt sign indicating number and easily make mistakes, mechanical unlocking mechanism easily gets rusty, the long-term use, open difficulty, give to manipulate and bring many inconvenience and trouble.

The purpose of this utility model is the defective that is latched at existing mechanical coding, and a kind of code electromalgnetic lock that can open automatically is provided.

The purpose of this utility model is achieved in that code electromalgnetic lock has a lock body and continuous shank of the key thereof, electromagnetism unlocking mechanism and control circuit are installed in lock body, in the single-chip microcomputer of control circuit, deposit the coding and the application program of this lock in, on shank of the key, be equipped with bucker, bottom at lock body is equipped with power coupling, also has the emergency key hole in a side of lock body.The computer key of opening code electromalgnetic lock is through the palm PC after the transformation of the way, at its front end permanent magnet and positive and negative electrode have been installed, go into coding application program at its store memory, change system into the computer key of opening this code electromalgnetic lock, other is furnished with the magneto emergency key.

The code electromalgnetic lock that the utility model provides owing to adopted the contactless sign indicating number and the working method of auto-unlocking read, make its adopt sign indicating number accurately, unblank fast, simple to operation, improve the sealing performance of lockset simultaneously, be difficult for getting rusty, prolonged the application life of lockset.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structure sectional view of the utility model code electromalgnetic lock.

Fig. 2 is the structure sectional view of the utility model computer key transformation of the way part.

Fig. 3 is the structure sectional view of the utility model emergency key.

Fig. 4 is the circuit theory diagrams of the utility model code electromalgnetic lock.

The structure of code electromalgnetic lock as shown in Figure 1, shank of the key 1 is inserted in the lock body 3, bucker 2 is installed on the shank of the key 1, prevent that rainwater from entering in the lock body, side at lock body has aperture, is provided with banking pin 4 in the hole, in order to the unlatching distance of restriction shank of the key 1, spring 5 withstands the lower end of shank of the key 1, has constituted the padlock body structure.The electromagnetism unlocking mechanism of opening in order to control shank of the key 1 is installed in lock body 3, and described electromagnetism unlocking mechanism is an electromagnet, and electromagnet is fixed on the lock body 3 by screw 12, and it is made up of magnet frame 8, coil 9, iron core 10, armature 11 and return spring 13.Groove corresponding to shank of the key 1 lower end on armature 11 has a protruding block A, when shank of the key 1 inserts, effect lower convexity piece A at return spring 13 enters in the groove of shank of the key 1, and block shank of the key 1, make lock be in closure state, and protruding block A withdraws from the groove of shank of the key 1 when electromagnetic actuation, and lock is opened.Opposite side at lock body 3 has emergency key hole 7, blind hole is made in this hole, be in order to improve the sealing performance of lockset, and is furnished with under special circumstances the emergency key that uses, described emergency key structure as shown in Figure 3, it includes barred body 21 and hollow permanent magnet 20, is fixed together by screw 19.The prolongation B of armature 11 is corresponding to emergency key hole 7, when emergency key inserts, prolongation B on the armature 11 moves to the emergency key position under magneticaction, thereby make protruding block A withdraw from the groove of shank of the key 1, lock is opened, armature 11 is that ferroic material is made, and has realized contactless emergent unlocking.Printing version 6 is installed in the bottom of lock body 3, on printing version 6, control circuit is installed, described control circuit as shown in Figure 4, it includes single-chip microcomputer U1, in the memory of single-chip microcomputer U1 with the coding of application program and this lock, resistance R 2, capacitor C 1 has constituted the RC oscillator, for U1 provides stable frequency of oscillation, L1 is a magnet spool, and V1 is the switching tube of L1, and V2 is an infrared transmitting tube, V3 is an infrared receiving tube, R1, R3, R4 is a current-limiting resistance, and S1 is a contact, is installed in the next door of shank of the key 1 lower end, when electromagnetic lock contacts with shank of the key 1 during at closure state, when electromagnetic lock during in opening and shank of the key 1 disconnect, because of lock body 3 links to each other with the control circuit negative pole with shank of the key 1, in order to the folding condition of judgement electromagnetic lock, X1 and X2 are the power couplings of electromagnetic lock, be installed in two holes printing version 6, an end is exposed on the outside, the other end respectively with control circuit just, negative electricity connects.

Computer key selects for use the transformation of the way of THINPAD-600 type palm PC to form, this type palm PC has possessed infrared emission and the infrared function of accepting, go into the application program of coding control at its store memory, hardware transformation of the way part as shown in Figure 2, front end at housing 14 is fixed with hollow permanent magnet 15 and 17, electrode 16 and 18 are installed in permanent magnet 15 and 17, and electrode 16 and 18 1 ends are exposed on the outside, and the other end is electrically connected with the positive and negative electrode of circuit respectively.

In the time of need unblanking, the electrode 16 and 18 of computer key is touched the power coupling X1 and the X2 of electromagnetic lock, because of X1, X2 is the ferroic material manufacturing, permanent magnet 15 and 17 is very fast with its magnetization and firmly adhesive, this moment, electromagnetic lock obtained working power, the coded data of storage in the single-chip microcomputer U1, V2 sends by infrared transmitting tube, after computer key receives coding, compare, encode and send unlock instruction with infrared mode when correct with the coding of prior storage, after receiving unlock instruction, infrared receiving tube V3 in the electromagnetic lock is transferred to single-chip microcomputer U1,1 human hair combing waste of U1 goes out a pulse makes the V1 conducting, and magnet spool L1 gets electric adhesive, and lock is opened.When code error, lock and do not open.
