Anti-theft lock

Abstract

The invention discloses an anti-theft lock, which is mainly characterized in that cross slots (16) which are mutually symmetric are arranged in the axial direction of a lock core (15), the cross slots are communicated with all accommodating slots (17) on the lock core, cross pins (10) are arranged in the cross slots, a V-shaped surface is formed on one side of each cross pin relative to the central line of the lock core, the V-shaped surfaces are matched with V-shaped grooves (4), convex pillars (11) are arranged at two ends of the cross pins (10), a hole slot (12) which is matched with the convex pillars is formed on a key (13), long slots (2) which are matched with the cross pins (10) are formed on the inner wall of a lock shell (1), a fine slot (18) is formed on the circumference of the lock core (5), an elastic device is arranged in the fine slot, and the elastic device is in contact with the cross pins. The lock with the structure can lead the key to insert in two ways, have enough space for arranging the elastic device on the circumference of the lock core and realize simple structure and good anti-theft performance.

Description

technical field [0001] The invention relates to a hardware lockset. Background technique [0002] At present, there are many kinds of locks on the market, with different structures and various performances. Check the Chinese patent, the authorized announcement number is CN117911C, and the name is an invention patent of a kind of anti-theft tumbler lock head and key. The content of the invention is described as follows: "A The pin lock head includes a lock body, a lock cylinder, a pin, a pin return spring, and a shift fork. The inner side of the groove communicates with the side of the pinhole and is roughly perpendicular to the pinhole. The outer side of the side column groove can correspond to the square groove inside the lock body. There is a locking post, the inner side of which is ∧-shaped, which can be matched with the ∨-shaped groove on the marble; the outer side of the locking post is square, which can be matched with the square groove inside the round hole of the lo...

AI Technical Summary

Problems solved by technology

[0005] The lock with this structure solves the problem of complex processing of the internal structure of the horizontal pin lock cylinder because the horizontal pin is pressed by the elastic device in the thin groove around the lock cylinder, and the structure is simplified and the anti-theft performance is increased. Will give the majority of user agents a positive practical effect
