The first lock tongue 5, the second lock tongue 6, the outer lock cylinder 3, the electromagnet 10, the baffle 8 and the connecting sheet 7 are arranged in the base, and the inner lock cylinder 4 and the key 9 are arranged on the front cover 12.

The first lock tongue 5 comprises an inner lock tongue 51 and an outer lock tongue 52, a connecting column 55 is arranged at the tail of the inner lock tongue 51, a bottom plate 54 is arranged at the tail of the outer lock tongue 52, and the connecting column 55 passes through the first spring 56, then passes through the bottom plate 54, and then is connected with a second spring 57 at the tail of the bottom plate 54. The first lock tongue clamping block 53 is arranged on the side face of the outer lock tongue 52, the connecting piece 7 is provided with the connecting piece clamping groove 71, and the first lock tongue 5 can be limited by matching the connecting piece clamping groove 71 with the first lock tongue clamping block 53.

Be provided with first spacing post 13 and second spacing post 14 in the base, through first spacing post 13 and second spacing post 14, can restrict the rotation scope of connection piece 7, can restrict the range of motion of separation blade 8 through second spacing post 14 and electro-magnet 10. The bottom of the baffle 8 is provided with a baffle groove 81, and the connecting piece 7 can be clamped through the baffle groove 81.

The electromagnet 10 is arranged beside the baffle 8, the baffle 8 is adsorbed by the electromagnet 10, the limit of the connecting sheet 7 to the outer lock tongue 52 can be released, unlocking is completed, the V-shaped elastic sheet 91 is arranged below the key 9, the baffle 8 can be extruded through the V-shaped elastic sheet 91, and therefore the limit of the connecting sheet 7 to the outer lock tongue 52 can be released, and unlocking is completed. The electromagnet 10 is electrically connected with an external unlocking device through a connecting wire, and the external unlocking device can be a fingerprint unlocking device, a key unlocking device, an IC card unlocking device or a wireless unlocking device.

Be provided with on the second spring bolt 6 and stir the groove 61, outer lock core 3 bottom is provided with outer lock core plectrum 31, and interior lock core 4 bottom is provided with interior lock core plectrum 41, through outer lock core plectrum 31 and interior lock core plectrum 41, the user can rotate interior lock core 4 or outer lock core 3 through the key, drives the flexible of second spring bolt 6.

The second lock seat 2 is provided with a first lock hole 21 corresponding to the first lock tongue 5, a second lock hole 22 corresponding to the second lock tongue 6 and a limiting seat 24, a rotatable pulley 26 is arranged on the limiting seat 24, the top of the limiting seat 24 is also provided with a limiting seat clamping block 25, the second lock seat 2 is provided with a second lock seat clamping groove 23, and the second lock seat clamping groove 23 and the limiting seat clamping block 25 can be matched, so that the limiting seat 24 arranged on the second lock seat 2 is limited.

When the first locking bolt 5 is disposed in the first locking hole 21, under the extrusion of the pulley 26, the inner locking bolt 51 is in a compressed state, that is, the first spring 56 and the first spring 56 between the inner locking bolt 51 and the outer locking bolt 52 are compressed, and the first spring 56 is in a compressed state, and since the blocking piece 8 blocks the connecting piece 7, the connecting piece 7 blocks the outer locking bolt 52, so that the outer locking bolt 52 is in a normal state, and the second spring 57 is also in a normal state.

When a user uses the external unlocking device to unlock or uses the key 9 to unlock, the connecting sheet 7 releases the restriction on the external lock tongue 52, so that under the drive of the first spring 56, the first spring 56 stretches, the external lock tongue 52 compresses, the second spring 57 is in a compressed state, and both the first spring 56 and the second spring 57 are in a compressed state at the moment.

When the user pulls the door, the first spring 56 and the second spring 57 simultaneously release the compression state, so that the outer lock tongue 52 and the inner lock tongue 51 are both reset, and simultaneously drive the connecting piece 7 to reset, so that the door is simultaneously returned to a locked state.

The door lock has a certain mute effect by using the limiting seat 24 and the pulley 26 on the limiting seat 24, and the door lock is more concise and attractive in appearance due to the design without a handle. The design of the external unlocking device is used, so that the expansion of the door lock is stronger, the proper external unlocking device can be selected according to actual needs, and the external unlocking device is not limited to an unlocking mode fixed on a door lock, so that the application range of the door lock is enlarged, for example, if the door lock is used as a gate lock, fingerprint unlocking or wireless unlocking can be used, and if the door lock is used as a door lock in a house, the door lock can be set to be unlocked by a simple key.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the present invention and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present invention.
