Abstract

The invention discloses a coaxial two-cylinder invisible lock which comprises an inner lock cylinder and an outer lock cylinder. The lock is characterized in that the outer lock cylinder is provided with a lock hole, a through hole is formed in the circle center of the lock hole, a poking block is arranged at the upper end of the through hole, a groove is formed in the connection portion of the inner lock cylinder and the outer lock cylinder and enables the inner lock cylinder and the outer lock cylinder to move oppositely, a sheet gear is arranged in a lock body of the inner lock cylinder, a cavity matched with the fixed end of the outer lock cylinder is formed in the upper portion of the sheet gear, an invisible spring is disposed between the groove and the cavity, and a notch capable of containing the invisible spring is formed in the outer lock cylinder. The lock has the advantages that compared with a coaxial two-cylinder lock in the prior art, the manufacturing technology is simpler, and the percent of pass of finished products is greatly increased.

Description

technical field [0001] The invention relates to the field of anti-theft locks, in particular to a coaxial double-core invisible lock. Background technique [0002] Mechanical locks are very commonly used household appliances. There are many types of mechanical locks, but the anti-theft performance is an important indicator for evaluating the quality of a lock. The mechanical lock of the traditional structure makes the lock cylinder and the lock sleeve rotate relatively through the cooperation of the key and the pin in the lock cylinder, and then the lock cylinder drives the bolt to move the tenon to realize unlocking and locking. But the anti-theft function of the above-mentioned lockset is poor, as long as a certain torque is applied to the lock cylinder, and the pin is pressed down with a specific tool, the lock can be realized. Aiming at preventing technical unlocking, the mechanical lock is improved. There is a coaxial double-core lock in the prior art, but its workma...
