Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1

Referring to fig. 1-3, an intelligent security system uses the anti-theft lock, including outer lock core 1 and inner lock core 7, the outer lock core 1 is equipped with a plurality of chutes 3, each chute 3 is connected with the outer marble 4 of different length through the spring 2, the inner lock core 7 is equipped with a plurality of inner marbles 5 slidably, and the specification of each inner marble 5 matches with the specification of the corresponding outer marble 4, the inner lock core 7 is equipped with the slot 6 for the key to insert;

the front end of the outer lock cylinder 1 is provided with a trigger core 9 in a sliding manner, the trigger core 9 can rotate in the circumferential direction and cannot move linearly, a control box 12 is installed in the trigger core 9, a power mechanism is arranged in the control box 12 and comprises a receiver 14, a controller 15 and an alarm 16, the receiver 14 is used for receiving and analyzing an electric signal sent by a static contact 18, when the change of the electric signal is different from a preset value, the controller 15 controls the alarm 16 to give an alarm, a shielding layer 13 is further arranged on the inner side wall of the control box 12, the shielding layer 13 is made of a high-permeability material and used for shielding an external electromagnetic signal, and therefore the phenomenon that the motor mechanism fails is avoided;

a guide hole 10 penetrates through the trigger core 9, the guide hole 10 is communicated with the slot 6 and is coaxial, a clamping groove 11 and an annular groove which are communicated with the guide hole 10 are formed in the inner side wall of the guide hole 10, an annular plate 8 is rotatably arranged in the annular groove through a bearing, a movable contact 18 which is electrically connected with a receiver 14 is fixedly arranged in the annular groove, and a static contact 17 is arranged on the annular plate 8.

When the lock is used in the embodiment, a tooth groove matched with the shape of a key is formed in the inner lock cylinder 7, the outer marble 4, the inner marble 5, the sliding groove 3 and the like are common structures in a lock, and are not described herein again, the shape of the clamping groove 11 is the same as that of one tooth groove, namely, the shape of one tooth on the corresponding key is assumed that the clamping groove 11 is matched with the first tooth of the key;

before the key is completely inserted into the slot 6, the front end of the key needs to be inserted into the guide hole 10 and then the key is rotated, under the clamping of the clamping groove 11 and the key, the trigger core 9 rotates along with the rotation of the key, because the annular plate 8 is connected with the annular groove through the bearing, the annular plate 8 cannot rotate along with the rotation of the trigger core 9, when the key rotates clockwise for one circle, the static contact 17 on the annular plate 8 can be contacted with the movable contact 18 once to generate a forward electric signal, which is recorded as '1', and similarly, when the key rotates anticlockwise for one circle, a reverse electric signal can be generated and recorded as '0';

when the password of the anti-theft lock is set, the anti-theft lock can be randomly arranged and combined, if the key is rotated for two weeks in the forward direction, the receiver 14 judges whether the received signal conforms to '11', if the received signal does not conform to the '11', the controller 15 controls the alarm 16 to send out an alarm once (the alarm information can be directly sent to a mobile phone end or a computer end through the wireless network module);

After the key is rotated to enable the trigger core 9 to rotate according to a correct rule, the key is inserted into the slot 6, unlocking can be performed according to a normal mode, if the trigger core 9 is not rotated to directly unlock, the internal lock cylinder 7 and the trigger core 9 simultaneously rotate to also cause triggering of the alarm 16 (a common anti-theft lock generally needs to be twisted for at least one circle to unlock, which is equivalent to generation of an electric signal), a complex algorithm chip is not needed in the embodiment, the password combination mode is more (every time a moving contact 18 is added, the combination result can be geometrically increased, if the anti-theft lock positively rotates for a half circle and then reversely rotates for a circle and the like), the anti-theft lock is suitable for security systems of places such as factories and warehouses, and after an alarm signal is.

Example 2

Referring to fig. 4, the present embodiment is different from embodiment 1 in that: a solenoid coil 19 is fixedly mounted on the inner top wall of one of the chutes 3, and a magnetic block 20 is fixedly mounted at the upper end of the corresponding outer pin 4.

When this embodiment uses, solenoid 19 is in charged state all the time, and solenoid 19 during the circular telegram can produce a magnetic field that repels with magnetic path 20, makes in the unable spout 3 that slides of interior marble 5 that corresponds, and the lock also can't be opened, only when rotating according to the correct mode and triggering behind the core 9, controller 15 just can make solenoid 19 short-term outage through a miniature relay, and the lock just can be opened through the key this moment, and this embodiment is applicable to most security protection system.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
