Abstract

The invention discloses a multifunctional anti-theft lock core body and a key. The lock core is installed in the central hole of the lock head, and the outer circumference of the lock head is provided with a pin hole and a radial pin hole in the axial direction. The radial pin hole is equipped with a radial lower pin, a radial upper pin and a radial pin spring. There is a boss groove inside the lock cylinder; a boss is arranged axially on the outside of the front lock cylinder, an axial marble groove is opened in the center hole of the front lock cylinder, a circular groove is opened on the front lock cylinder, and an axial opening is opened on the boss There are radially lower pinholes, the radially lower pinholes correspond to the radially upper pinholes, and the radially lower pinholes communicate with the circular groove; there is a pin groove in the central axis of the rear lock core body, and the positioning pin passes through the pinhole and the pinhole. Groove matching, the center hole of the snap ring is evenly distributed along the circumference with square slots for the snap ring; the key post is provided with a serrated section along the axial direction, and the serrated section is matched with the radial lower pins, and the outer surface of the key ring is provided with a bump groove, the key post The bumps are embedded in the bump grooves and move. The invention has the advantages of simple structure, low cost and convenient installation, and can be used for various anti-theft door locks.

Description

technical field [0001] The invention relates to a lock core body and a key, in particular to a multifunctional anti-theft lock core body and a key. Background technique [0002] Locks are widely used in daily life. In the safety standards of locks, the anti-technical opening performance of the lock head / lock cylinder is the short board of its comprehensive safety performance. Nowadays, the anti-technical opening performance of the lock cylinder cannot satisfy people. . At present, most of the lock cylinders used by families and business units are still mainly pin locks. The pin locks have the advantages of simple structure, convenient manufacture and low cost. Due to the relatively simple structure of the more common radial pin lock, criminals can easily use criminal tools such as master keys or hook tools to open the lockset. [0003] Although some new anti-theft lock cylinders have also appeared on the market in recent years, such as: [0004] Patent CN201220471908.7 in...
