The invention relates to a dislocation transmission mechanical anti-theft lock cylinder and a matching key. The anti-theft lock cylinder comprises a lock cylinder body, the lock cylinder, a fixed ring, a rotary ring, a lock hole, a transmission mechanism and the matching key, wherein each elastic element group consists of four ball elastic elements with the same diameter, a cylindrical elastic element and a spring, two elastic element groups are formed according to different elastic element arraying sequences, and the wave heights or wave trough depths of a tooth profile of the cross matching key are equal to the diameters of the ball elastic elements. The length of the cylindrical elastic element is equal to the thickness of the fixed ring and is integer multiples of the diameters of the ball elastic elements. The lock cylinder is arranged in the fixed ring, the rotary ring is arranged outside the fixed ring, elastic element holes in each elastic element group are axially arrayed on a circumferential cross section at intervals, and the lock cylinder can be rotated for an angle of above 360 degrees along the forward direction and the backward direction. When the matching key is rotated, elastic element holes in the lock cylinder are staggered and separated from the other elastic element holes in the corresponding elastic element group, the rotary ring can then be rotated, furthermore, an unlocking actuating mechanism is driven, and a strong anti-theft function is obtained.

The invention discloses an ice ball lock system with an active warning function and relates to the technical field of ice ball locks. The ice ball lock system has the advantages that a lock cylinder is not likely to be drilled, and a warning can be given actively when a key insertion hole of an ice ball lock is drilled. The ice ball lock system comprises an ice ball lock body, a protective jacket, a mobile phone, a warning center, a controller and a wireless module connected with the controller. The wireless module can be in wireless connection with the mobile phone and the warning center under instructions of the controller correspondingly. If the controller receives pressure signals uploaded by a pressure detection sensor, short-distance temperature signals uploaded by a short-distance temperature detection sensor, long-distance temperature signals uploaded by a long-distance temperature detection sensor, vibration signals uploaded by a vibration detection sensor and drilling sound signals uploaded by a drilling sound detection sensor simultaneously and the short-distance temperature signals are larger than the long-distance temperature signals, the controller gives information that someone is drilling the ice ball lock to the mobile phone of a user or the warning center by means of the wireless module, and then the user or the warning center can conduct corresponding processing.

The invention discloses an ice hockey lock system with an active alarming function, and relates to the technical field of ice hockey locks. An ice hockey lock is provided with a lock cylinder not prone to being drilled, and when a key inserting hole of the ice hockey lock is drilled, an alarm can be actively given. The ice hockey lock system comprises an ice hockey lock body, a protection sleeve, a mobile phone, an alarm center, a controller and a wireless module connected with the controller. The wireless module can be in wireless connection with the mobile phone and the alarm center through an instruction of the controller. If the controller receives pressure signals uploaded by a pressure detection sensor, near temperature signals uploaded by a short-distance temperature detection sensor, far temperature signals uploaded by a far-distance temperature detection sensor, vibration signals uploaded by a vibration detection sensor and drilling sound signals uploaded by a drilling sound detection sensor at the same time and the near temperature signals are larger than the far temperature signals, the controller immediately sends the information that somebody drills the ice hockey lock to the mobile phone of a user or the alarm center through the wireless module, and the user or the alarm center can do corresponding treatment accordingly.

The invention discloses an ice ball lock system capable of achieving automatic alarm, and relates to the technical field of ice ball locks. An ice ball lock is provided with a lock cylinder, thereby being not likely to be drilled. When a key inserting hole of the ice ball lock is drilled, an alarm can be actively given. The ice ball lock system comprises an ice ball lock body, a protective sleeve, a mobile phone, an alarm center, a controller and a wireless module connected with the controller. The wireless module can be in wireless connection with the mobile phone and the alarm center correspondingly under the instruction of the controller. If the controller simultaneously receives a pressure signal uploaded by a pressure detection sensor, a short-distance temperature signal uploaded by a short-distance temperature detection sensor, a long-distance temperature signal uploaded by a long-distance temperature detection sensor, a vibration signal uploaded by a vibration detection sensor and a drilling sound signal uploaded by a drilling sound detection sensor and the short-distance temperature signal is larger than the long-distance temperature signal, the controller immediately gives an alarm to the mobile phone of a user or the alarm center through the wireless module to indicate that somebody drills the ice ball lock, and then the user or the alarm center can carry out corresponding treatment.

The invention discloses a coaxial two-cylinder invisible lock which comprises an inner lock cylinder and an outer lock cylinder. The lock is characterized in that the outer lock cylinder is provided with a lock hole, a through hole is formed in the circle center of the lock hole, a poking block is arranged at the upper end of the through hole, a groove is formed in the connection portion of the inner lock cylinder and the outer lock cylinder and enables the inner lock cylinder and the outer lock cylinder to move oppositely, a sheet gear is arranged in a lock body of the inner lock cylinder, a cavity matched with the fixed end of the outer lock cylinder is formed in the upper portion of the sheet gear, an invisible spring is disposed between the groove and the cavity, and a notch capable of containing the invisible spring is formed in the outer lock cylinder. The lock has the advantages that compared with a coaxial two-cylinder lock in the prior art, the manufacturing technology is simpler, and the percent of pass of finished products is greatly increased.
