Key cylinder and key

Abstract

The invention discloses a key cylinder. The key cylinder comprises a lock case, a cylinder core and a key. A keyhole is formed on the cylinder core, a front locking device is arranged on the top of the lock case and the cylinder core, and a side locking device is mounted on the side face of the lock case and the cylinder core; the side locking device comprises side ball pressure springs, side balls, pressure springs of a transverse sheet and the transverse sheet; key sliding grooves where a part of a key slides are formed on the side balls; transverse sheet sliding grooves where a part of the transverse sheet slides are formed under the side walls; a tooth pattern which is matched with the front locking device for unlocking is arranged on a surface of the key, a raised line which is matched with the key sliding grooves of all side balls and pushes to side balls to move left and right is arranged on the other surface of the key, and the raised line protrudes out of the surfaces of the side balls and is arranged in an extended manner along the length direction of the key. The key cylinder and the key disclosed by the invention have the advantages of simple structure and good stir-up and burglar resistance.

Description

【Technical field】 [0001] The invention relates to a lock cylinder and a key. 【Background technique】 [0002] Most of the lock cylinders on the market are relatively simple in structure, and people have thoroughly studied it, and thieves can easily open it in just a few seconds, so the current lock cylinders have poor anti-theft performance, which will endanger the lives and lives of the people. Property safety has brought very big threat, can't satisfy the most basic theftproof requirement of the people to lock cylinder. [0003] At present, there are lock cylinders with pins in three directions on the market. The lock core includes front pins, side pins and bottom horizontal piece. With the matching curved groove, although the lock cylinder of this structure has higher anti-theft performance than ordinary locks, due to the existence of the spring pin, it protrudes from the side pin, so that the thief can use professional tools to provoke the spring pin to unlock.

[0002] Most of the lock cylinders on the market are relatively simple in structure, and people have thoroughly studied it, and thieves can easily open it in just a few seconds, so the current lock cylinders have poor anti-theft performance, which will endanger the lives and lives of the people. Property security has brought a great threat, and it can no longer meet the people's most basic anti-theft requirements for lock cylinders.

[0003] At present, there are lock cylinders with pins in three directions on the market. The lock core includes front pins, side pins and bottom horizontal piece. With the matching curved groove, although the lock cylinder of this structure has higher anti-theft performance than ordinary locks, due to the existence of the spring pin, it protrudes from the side pin, so that the thief can use professional tools to provoke the spring pin to unlock. The purpose, because it is necessary to further improve the anti-theft performance of the lock cylinder
