Abstract

An electromechanical lock has a rotating insert (5) with a cam (8) placed in a body (1) and a shaft (4) is inserted into a bore (7) of the rotating insert (5) and a shaft (4) comprises an electromagnet (10) with an anchor (11) which co-operates with sides of a slot (3) of the rotating insert (5) in such way that at simultaneous transmitting of a voltage on the electromagnet (10) and at rotation of the shaft (4) the anchor (11) rests against the side of the slot (3) of the rotating insert (5) transmitting it the rotation from the shaft (4), and at absence of a voltage on the electromagnet (10) and a rotation of the shaft (4) the anchor (11) pulls out of the slot (3) under the action of its own weight and the rotation from the shaft (4) does not transmit to the rotating insert (5).

Description

Electromechanical lock

Technical field

The present invention relates to electromechanical lock.

Background technology

Electromechanical lock SU 972024 is known, and this lock comprises the closed latch (bolt) of the spring load of inserting lock housing and a spring load insert with dead bolt that matches with this latch.The mechanical device that pins lock housing comprises the fixator of an electromagnet and this electromagnet, and this fixator means this latch of locking.

Electromagnet uses a large amount of electric energy in the lock position, do not allow lock is carried out the little energy supply of independence.

Invention discloses

An object of the present invention is to create a lock that can work long hours by independent micro unit energy supply; And create a lock that does not have the energy supply unit and carry out work by energy supply unit built-in in key.

Electromechanical lock according to this purpose comprises the rotation insert of inserting lock housing, and one means that locking or the dead bolt and that matches with the closed latch of the spring load of inserting lock housing are inserted into the driving shaft in rotation insert hole.This driving shaft comprises the electromagnet with fixator, this electromagnet matches in the mode of importing electromagnet simultaneously with the groove of rotation insert, when axle rotates, this fixator leans against the end face of the groove of rotation insert, the rotation of transmission axle, when not having the voltage of electromagnet, this fixator is pushed out groove under the effect of its deadweight or spring, and Zhou rotation is not transferred to the rotation insert like this.

The voltage of electromagnet is transmitted by apparatus for security code recognition, this password is the whole microcircuit generation by the inner chamber of inserting axle, under the condition of unanimity, this password is kept in the apparatus for security code recognition, this password enters its inlet by key, for this purpose, a contact base places the flush end of axle or induction coil with transmission electronic energy under the situation that does not have contact, and a password pulse train is electrically connected with the inlet of apparatus for security code recognition.

For externalities is done maximum protection; making a contact base in axle is possible to insert little energy supply; can allow password to be imported in the lock by Long-distance Control; it is necessary being electrically connected an optical instrument or wireless aerial to substitute contact base with the inlet of apparatus for security code recognition, opens password like this and be exactly optical signal or corresponding radio signal by the key emission.

Make the best mode of invention

The present invention relates to a lock with lock housing 1 as shown in fig. 1, lock housing 1 has been inserted rotation insert 5, and the flush end of rotation insert 5 freely is fixed on the end face of lock housing 1.Rotation insert 5 has a hole 7, is transferred to rotation insert 5 by this hole rotation from door handle or key.Dead bolt 8 is rigidly connected with rotation insert 5, and dead bolt 8 means locking.Axle 4 is inserted in the hole 7 of rotation insert 5.

Axle 4 has a hole, in the electromagnet 10 that contains fixator 11 is arranged, this fixator can move freely along the vertical axis of axle 4.Rotation insert 5 has a groove 3.In the position that locking closes, fixator 11 enters groove 3 by the effect of its deadweight.After axle 4 Rotate 180 degree, fixator 11 passed through the end face of groove 3 and the groove 3 of fixator 11 engagements before leaving under the effect of its deadweight.Like this, axle 4 can be done 360 and spends and freely rotate and do not lock and be opened in the hole 7 of rotation insert 5.

In order to open lock, need be in axle 4 rotations the voltage of transmission electromagnet 10, rotate 11 pairs of electromagnets of 180 degree fixators 10 then and keep promoting positions, and with the end face engagement of groove 3, like this, the rotation of axle 4 will be transferred to rotation insert 5.For being further rotated of axle 4, rotation insert 5 rotates and closed dead bolt 8 moves to the position that lock is opened shown in Fig. 2 with rotation insert 5.

In order to close locking, need turning cylinder 4 in the opposite direction, is nonessential with voltage transmission to electromagnet, because as shown in Figure 1, fixator 11 enters groove 3 to axle 4 under the effect of its deadweight, for being further rotated of axle 4 when rotation takes place, fixator 11 meshes with the end face of groove 3, and with rotation be transferred to the rotation insert 5, like this, dead bolt 8 is moved to the position that locking closes.In extreme position " unlatching ", " closure ", dead bolt 8 is fixed with the frictional force of its deadweight and lock housing and wall.

The voltage of electromagnet 10 is from making apparatus for security code recognition 13 transmission of password by the whole microcircuit the inner chamber that is placed into axle 4 as shown in Figure 3.Voltage is under the condition consistent with the password in the memory that is kept at apparatus for security code recognition 13, and password enters its inlet.Password is continuous electronic impulse at the inlet of apparatus for security code recognition 13 by a contact base 12 transmission, and as shown in Figure 5, this socket is to be electrically connected or to place the induction coil of the flush end of axle 4 to connect by one.

For the external action of axle 4 being carried out maximum protection, as shown in Figure 3, compartment 9 is placed into, and the micro unit that energy supply 6 is arranged in it is to provide the independent input of apparatus for security code recognition 13.Its allow to accept one by optical instrument or insert the discontiguous password of wireless aerial of the flush end of axle 4, and is electrically connected with the inlet of apparatus for security code recognition 13.

In order to reduce the invalid angle of turning cylinder 4, shown the spring 2 of inserting groove 3 among Fig. 4, when fixator 11 is spent along with axle 4 rotations 30, spring 2 is released groove 3 with fixator 11, transmission voltage on electromagnet 10, spring 2 is back-outed, and the end face of fixator 11 and groove 3 meshes and will rotate from axle 4 and is transferred to rotation insert 5.

For the purpose of the reliability that increases lock, processing has the mode of the lock of latch, as shown in Figure 4, is possible.

For this purpose, a closed latch 14 places lock housing 1 and matches with the dead bolt 8 of rotation insert 5.

Industrial applicibility

Originally the lock that has closed dead bolt tends to be installed on the inside door of building and on the door of furniture.

Originally the lock that has closed latch tends to be installed on the entrance door in building and other are intended to restriction and do not have and award The structure that the power people enters.
