Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, a pinhole lock includes a casing 1, and a main shaft 11 protrudes from the casing 1, the main shaft 11 is connected with a bearing 10, and the main shaft 11 passes through the cylindrical rear lock cylinder 2, the cylindrical middle lock cylinder 3 and the cylindrical The center of the front lock core 4, and the above-mentioned three lock core spindles can rotate circumferentially; the rear lock core 2 has several through holes in the axial direction, and the rear lock rod 21 is inserted in the through hole, and the rear lock rod 21 is covered with a spring 9, The middle lock core 3 is also provided with a through hole corresponding to the rear lock core 2, and the front lock core 4 is also provided with a through hole corresponding to the middle lock core 3, and the front lock rod 8 is inserted in the through hole of the front lock core 4. Front lock bar 8 overcoat has spring 9, and front lock bar 8 and rear lock bar 21 all can s...

Abstract

The invention discloses a pinhole lock, which comprises a shell; a main shaft is projected out of the shell; the main shaft passes through centers of a cylindrical rear lock cylinder, a cylindrical middle lock cylinder and a cylindrical front lock cylinder in sequence, and the main shaft of the three lock cylinders can rotate circumferentially; the rear lock cylinder is provided with a plurality of through holes in an axial direction; a rear lock rod is inserted in the through hole; the rear lock rod is sleeved with a spring; the middle lock cylinder is also provided with through holes corresponding to that of the rear lock cylinder; and the front lock cylinder is also provided with through holes corresponding to that of the middle lock cylinder. The invention has the advantages that the pinhole lock does not have a large lock hole, so the anti-theft effect is good, and a picklock tool cannot be inserted into the lock.

Description

technical field [0001] The invention relates to a lock cylinder, in particular to a lock cylinder which adopts a pinhole lock cylinder to realize unlocking. Background technique [0002] Traditional lock cylinders all adopt marbles or lock cylinder rows, and the key is inserted in the lock hole to unlock. In such a lock hole, a thief can easily put a lockpicking tool into the lock cylinder to realize the lock, and the anti-theft effect is poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a novel pinhole lock. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a pinhole lock, including a shell, and a main shaft protrudes from the shell, and the main shaft passes through the cylindrical rear lock core, the cylindrical middle lock core and the cylindrical front lock in turn. center of the core, and the main shafts of the above three lock cores can rotate circumf...
