Problems solved by technology

The lock includes a lock body and a lock core in the lock body. The lock core is provided with a locking side column that matches the V-shaped groove on the blade. The blade in this lock can only be used with an ordinary key. There is only one form of tooth groove, or the tooth groove is set on the side of the key blade (external milling tooth groove), or it is set in the middle of the key blade (internal milling tooth groove), so that the key quantity of the lock is limited, The mutual opening rate is high, and the anti-theft performance is affected

Embodiment 1

[0016] See figure 1 , figure 2 , the lock head of the present invention comprises a lock body 1 and a lock cylinder 2 in the lock body 1. The lock cylinder 2 is provided with a plurality of blade pinholes 11 arranged horizontally along the axial direction, and the blade pinholes 11 and the keyhole 9 arranged axially Interconnected; each vane pin hole 11 is provided with two vane pins 6, 16 stacked as a group, and the middle part of the vane pin 16 and the end of the vane pin 6 in the vane pin group on the same side are respectively provided with a The bumps 8,10 in the keyhole, the other side of the blade pins 6,16 are respectively provided with V-shaped grooves 7, and the blade return springs 5, 16 are respectively arranged on the lock core 2 corresponding to the blade pins 6,16 in each group. 12. The lock core 2 is provided with a locking side column groove 3, and the locking side column groove 3 is provided with a locking side column 4 that can cooperate with the V-shaped...

Embodiment 2

[0021] Such as Image 6 As shown, a magnetic block 23 can also be set on the notch of the locking side column groove on the lock core, and a magnetic block 24 with the same polarity as the magnetic block 23 is correspondingly set in the groove on the locking side column, and the magnetic block can be used to The repulsive force between the block 23 and the magnet block 24 returns the locking leg (see Figure 7 ). Other structures are the same as in Example 1.

Abstract

The invention discloses an improved flat pin tumbler lock which adopts the milling tooth groove key and comprises a lock cylinder and the corresponding key; the lock cylinder comprises a lock body; a plurality groups of flat pin tumblers are arranged on the lock plug in the lock body; wherein, each group of flat pin tumblers is composed of two flat pin tumblers; in the groups of flat pin tumblers which are in the same side, the middle part of a flat pin tumbler and the end part of the other flat pin tumbler are respectively provided with projections extending to the key hole; a locking side post matched with the V-shaped groove on the flat tumbler is arranged on the lock plug; the key includes a key plate; an inner milling tooth groove and an outer milling tooth groove are respectively arranged on the lateral and middle parts of one side of the key plate; bits are arranged on the lateral walls of the outer milling tooth groove and the inner milling tooth groove. The improved flat pin tumbler lock has the advantages that the lock cylinder can adopt an inner and outer milling tooth groove key which is different from the structure of a common key; because the adopted key has the inner milling tooth groove and the outer milling tooth groove at the same time, the key amount is improved; the inter-unlocking rate is reduced and the lock has better theft protection property.

Description

technical field [0001] The invention belongs to locks, and in particular relates to an improved blade pin lock using a milled groove key. Background technique [0002] Among the existing locks, there is a kind of lock that utilizes blades to cooperate with locking side columns to lock. The lock includes a lock body and a lock core in the lock body. The lock core is provided with a locking side column that matches the V-shaped groove on the blade. The blade in this lock can only be used with an ordinary key. There is only one form of tooth groove, or the tooth groove is set on the side of the key blade (external milling tooth groove), or it is set in the middle of the key blade (internal milling tooth groove), so that the key quantity of the lock is limited, The mutual opening rate is relatively high, and the anti-theft performance is affected. Contents of the invention [0003] The object of the present invention is to provide an improved blade pin lock using a milled gr...
