The lock cylinder is in communication contact with the smart phone through the Internet, a user only needs to install a corresponding APP on the smart phone, and the interaction between the lock cylinder and the mobile phone APP is realized by adopting the prior art; when a legal key is inserted into the keyhole 21 to unlock, the third lower ball 76 is touched and lifted up, so that the third upper ball 74 is pushed up, and the second contact switch 72 is triggered; at the moment, the lock cylinder can send a signal to the mobile phone, so that a user knows that a legal key is used for unlocking; the function is designed to be started through the smart phone APP after a user loses a legal key, so that whether the user uses the picked legal key to unlock can be known in time; simultaneously, this APP still supports the image reading, and the user can set up the camera on its outer wall or other places of door, and the camera work after triggering second contact switch 72 and being triggered shoots the people's that unblanks image and convey to user's smart mobile phone, in case of stealing, also can provide powerful clue and evidence for police's solution.

The relative positions of the locking triggering component 3, the locking executing component 4 and the unlocking reminding component 7 can be changed. The locking triggering component 3 and the unlocking reminding component 7 can have the same structure, but the realized detection functions are different, the locking triggering component 3 is used for detecting illegal keys, and the unlocking reminding component 7 is used for detecting legal keys, so that illegal persons can be prevented from stealing the legal keys to unlock the lock.

When a lawbreaker picks up a lock, violently unlocks the lock or unlocks the lock by using a tool or an illegal key or technology, the lawbreaker can touch the first lower ball 36 in the lock picking process because the existence of the first contact switch 32 is unknown, the first lower ball 36 moves upwards, so that the first upper ball 34 touches the button of the first contact switch 32 to trigger the first contact switch 32, the first contact switch 32 sends an electric signal to the electric control component 5, the electric control component 5 sends the electric signal to the locking component, and the locking component performs corresponding locking action, so that the lock is locked; there are various ways to unlock, such as: the electric control part 5 is controlled by using a mobile phone application program, and the locking is released; a timing device is arranged on the electric control part 5, and the locking is released after a preset period of time; a chip and a reset switch can be arranged on the holding part 61 of the legal key, when the legal key is inserted into the key hole 21, the chip is electrically connected with the electric control component 5, and then the reset switch is pressed, so that the locking is released; during the locking, no matter what kind of mode is used the tool to lock can't be opened, has realized preventing the technological effect of unblanking, has greatly promoted the security of tool to lock.

The first spring 33 plays a role of buffering between the first upper ball 34 and the first contact switch 32, the second spring 44 plays a role of buffering and returning between the first driving member 43 and the second upper ball 45, and the third spring 73 plays a role of buffering and returning between the second contact switch 72 and the third upper ball 74; the electric control part 5 is preferably mounted on the top end of the lock housing 1.

The first driving member 43 and the second driving member 47 may be solenoid valves or micro motors. The electromagnetic valve has the advantages of express action, small power, light appearance and the like, the response time can be as short as several milliseconds, and even a pilot electromagnetic valve can be controlled within dozens of milliseconds; the power consumption of the solenoid valve coil is very low, and the solenoid valve belongs to an energy-saving product and is suitable for products needing long-time standby, such as an electronic lock; the electromagnetic valve has small overall dimension, saves space and is convenient to be designed in the lockset; the first and second drivers 43, 47 may also be micro-motors.

The first contact switch 32 and the first upper bead 34 may be replaced with electric conductors, and electric wires are connected to the first contact switch 32 and the first upper bead 34, respectively; when the first contact switch 32 contacts with the first upper bead 34, a closed loop is formed, and the electronic control component 5 receives a signal forming the closed loop and then sends an electric signal to the locking component to execute a locking program to lock the lock cylinder; similarly, the second contact switch 72 and the third upper bead 74 may be similarly designed to detect the insertion of a legitimate key; however, when such a design is adopted, the lower end surfaces of the first upper bead 34 and the third upper bead 74 must be provided with an insulating layer to prevent a user from being injured by electric leakage when the lock is unlocked.

The first upper bead 34, the second upper bead 45 or the third upper bead 74 is of a primary-secondary bead structure; the first lower bead 36, the second lower bead 46 or the third lower bead 76 is of a primary-secondary bead structure; the first upper bead 34, the second upper bead 45, the third upper bead 74, the first lower bead 36, the second lower bead 46, or the third lower bead 76 may also be prior art solid pins; the upper bead and the lower bead shown in the figures of the application are both in a primary-secondary bead structure, so that the secret key rate is further improved.

Since the displacement of the first lower ball 36 will trigger the first contact switch 32, a key adapted to ensure that normal unlocking will not trigger the first contact switch 32 and that illegal key unlocking can be prevented. The utility model designs an adaptive key; referring to fig. 6 and 7, the key 6 includes a holding portion 61 and a bit portion 62, the bit portion 62 has a bit 621 engaged with the first lower bead 36, an open groove 622 is formed in the bit portion 62 along a key insertion direction, the bit 621 is located at the bottom of the open groove 622, that is, the bit 621 starts to open teeth from a bottom surface 6222 of the open groove 622; in operation, when the key 6 is inserted into the keyhole 21, the bottom surface 6222 of the open recess 622 is at a certain depth from the key surface 623, so that the bottom surface 6222 of the open recess 622 can ensure that the first upper bead 34 cannot trigger the first contact switch 32 before contacting and pressing the first lower bead 36 until the first lower bead 36 falls into the corresponding tooth 621, and the lock can be unlocked smoothly; however, when an improper key 100 or a foreign object, which is a non-matching key, is inserted into the cylinder liner 2, the surface of the improper key is attached to the side surface 22 of the keyhole close to the lower bead, and further, when the first lower bead 36 is contacted and lifted, the first upper bead 34 is lifted to a higher position, so that the first upper bead 34 touches the first contact switch 32, the first contact switch 32 is triggered, the locking component is actuated, the cylinder liner is locked, and the purpose of preventing the improper key from unlocking is achieved. The utility model discloses a key removes open groove portion, and other parts can be prior art's other structures according to the structure of complex lock, for example the utility model discloses tartar portion 62 in fig. 7 has two orbit grooves 624, 625, and open groove 622 is located the centre in two orbit grooves, the tank bottom in two orbit grooves is darker than open groove 622's bottom to distinguish orbit groove and open groove area.

The above embodiments are not intended to limit the scope of the present invention, and those skilled in the art will not depart from the present invention as it relates to the whole concept of the present invention, and the equal modification and change will still belong to the scope of the present invention.
