Anti-theft lock with two-section lock core having core-through and built-in code balls, and keys

Abstract

The invention relates to an anti-theft lock having a key and two cylinder sections provided with through-cylinder springs and letter springs, particularly an anti-theft lock with multiple cylinder sections for preventing technical unlocking and jimmying, and aims to design a novel anti-theft lock in order to more effectively prevent technical unlocking, jimmying and destructive unlocking. The technical proposal is to comprehensively strengthen the anti-theft function of the lock from multiple aspects such as the concealment of the cylinder springs, the prevention from unlocking by poking, as well as the structure of the key. The lock comprises a lock body, two cylinders, springs and a key and is characterized in that the lock is provided with a cylinder (2) having through-cylinder springs, a cylinder (6) with letter springs and two key sections (1); the cylinder having through-cylinder springs is mounted near the keyhole on the front end of the lock body (15), and then the cylinder having letter springs is installed with the end connected to poking pins (16).

Description

Technical field: [0001] The anti-theft lock with a two-stage lock cylinder and a key that goes through the core and a combination pin is a pin lock, and is especially suitable for a multi-stage lock cylinder anti-theft lock that is anti-technical and anti-prying. Background technique: [0002] There are many types of locks, including mechanical and electronic locks, and mechanical locks can be divided into pin locks and blade locks. Ordinary pin locks are mainly composed of a lock body, a lock cylinder, a pin and a key. The principle of unlocking a pin lock is that the teeth of the key make the pins that are inserted into the lock body and the lock core separate from the pins, so that the lock core and the lock body It can rotate without the insertion of a marble, and the lock cylinder drives the dead bolt to unlock. This kind of cylinder lock structure with one lock cylinder has poor anti-theft performance and is easy to perform technical unlocking. [0003] In order to im...

Problems solved by technology

Ordinary pin locks are mainly composed of a lock body, a lock cylinder, a pin and a key. The principle of unlocking a pin lock is that the teeth of the key make the pins that are inserted into the lock body and the lock core separate from the pins, so that the lock core and the lock body It can be rotated without the pin inserted, and the lock cylinder drives the deadbolt to unlock. This kind of pin lock structure with one lock cylinder has poor anti-theft performance and is easy to unlock technically.

[0003] In order to improve the performance of the anti-technical unlocking of the pin lock, people have come up with a pin lock with a multi-section lock cylinder structure afterwards, such as: the public number is CN2700479; the public number is the lock of CN2620745; In the body hole, the structure of each section of the lock cylinder is the same as that of the above-mentioned pin lock, which is equivalent to the superposition of the structure of the two pin locks. The difference is that the key doors of the two sections of the lock cylinder are not in the same position. The first section of the lock cylinder is aligned with the second section of the lock cylinder and the key door, and the key can enter the second section of the lock cylinder to continue unlocking. In this way, the lock is unlocked according to the section. Although this kind of lock improves the anti-theft performance of the lock, but in today's continuous advancement of technology, Still fail to completely and effectively prevent theft from unlocking
