Key identification code signal generator is installed on said lock body, this signal generator comprises the clamp spring hole of one group of overcoat coil at least, magnetic bail and spring are installed in this clamp spring hole, on said rotor, the rotor bail that can move up and down are installed with magnetic bail corresponding position.Key inserts the key hole of rotor during use, the magnetic bail moves up and down under the effect of key and spring, the times of exercise of each bail is determined by key shape, when staple moves up and down, the coil of clamp spring hole outside produces the different voltage signal of direction, to the amplification of encoding of these signals, can be used to discern that to insert in the keyhole be key or picklock.

Inlay the IC-card chip in the said key handle, the key front end is bumped into insulation materials, embeds the contact that is connected with the IC-card chip by lead on this insulation materials.

Said running contact device be with on the key the corresponding position of IC-card chip output contact on perforate, the metal bead is installed on the both sides in hole, separate with spring in the middle of the metal bead, with the bead corresponding position of running contact device arc shaped contact is installed on the said fixed contact device.

Said running contact device be with the position of on the key IC-card chip output contact corresponding position on perforate, in the hole, install both sides respectively with IC-card chip contacts and the contacted spring leaf of fixed contact device.

Prop up at said lock body and lock core place and to adorn an electronics lock pin, this lock pin upper end is installed in the epitrochanterian lockpin hole, the lower end magnetic bullet is installed in the lockpin hole on the lock body, in the lockpin hole on the lock body coil is installed, the locking spring is installed between this coil and the lock pin, the power-on of the output termination logic circuit of said electronic lock control, the output of IC-card and key identification code output connect respectively on IC-card decoder and the logic circuit, by the keying of their common control electronic locks.

Advantage of the present utility model is:

1, is difficult for being prized.Common latch lock is pried open by professional picklock easily, and combination lock is easily by feel or prison

Listen equipment to break a code, and the utility model lock core because of in established electronic lock, thereby difficult the sled;

2, key loss need not changed lock, as long as change password;

3, Ka keeping and security performance improve.Because of IC-card chip of the present utility model is embedded on the key, its

The keeping characteristic also just is better than magnetic card and IC-card;

4, the security performance of lockset improves.Because of the contact device of IC-card is located at lock core inside, thereby be difficult for being damaged.Peace

Full performance greatly improves.

In sum, the utility model organically combines common latch lock and IC card lock, on normal key

Embed the IC-card chip, solved the difficult problem of the difficult keeping of IC-card effectively; On the basis of common latch lock, increased mechanisms such as key identification code signal generator, IC-card chip contacts device, electronic lock, the theftproof performance of lockset is further improved.The utility model is simple in structure, and volume is little, and cost is low, and is easy to use, safe and reliable.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
