Description
Technical Field
The invention belongs to the field of lock cylinders, and relates to a multi-shifting-piece lock cylinder device which is particularly suitable for being used as a driving mechanism of an electronic lock.
Background
Removable lock cylinders are known in the art and are widely used in various door locks throughout the world, being the positive drive for the opening or closing of all mechanical door locks; along with the promotion of living demand, electronic lock is gradually advancing into thousands of families by virtue of its convenient advantage, and present electronic lock drive lock is mainly through the spring bolt flexible of square bar direct drive lock body.
The clutch device of the electronic lock directly driving the lock body through the square rod mainly comprises two types: the clutch is arranged in the lock body and controls the separation and reunion of the lock tongue and the square rod hole of the lock body; the external clutch, namely the clutch is arranged on the panel of the electronic lock, generally on the external panel and controls the clutch of the handle and the square bar of the electronic lock. However, no matter the clutch is built-in or external, as long as the electronic lock directly drives the lock body through the square rod, the electronic lock has certain requirements on the function of the lock body, for example: the electronic lock with the external clutch requires the lock body to have double-quick double-action function, while the electronic lock with the internal clutch gives all clutch execution tasks to the lock body, so that the common mechanical lock body in the existing market has no way to meet the lock body requirements of the electronic lock in function, and the electronic lock is called destructive installation in the industry because the sizes of the mechanical lock bodies in the current domestic market are various, and even the square rod position, the lock tongue size position and the like do not have uniform standards, so that the installation of the electronic lock becomes the largest bottleneck in the popularization process, and even the installation of the electronic lock in the afterloading market often needs to destroy the original structure of a door or a door frame.
In order to solve the bottleneck of electronic lock installation, in particular to realize the universal function of the electronic lock, the electronic lock is thoroughly pried and then sold in the big cake, and a plurality of electronic lock manufacturers develop electronic locks which realize the extension and retraction of lock tongues of lock bodies by driving lock cores; however, the electronic lock also has the problem of relatively poor use effect, and the reason for the problem is as follows: the existing lock core device on the market is generally a single-plectrum lock core device, and the plectrum rotates a circle in the forward direction or the reverse direction to shift the extension of a gear of the lock bolt of the lock body, however, the square bolt of the existing lock body generally has 1 to 2 gears, and the oblique bolt of the lock body needs the plectrum to rotate a circle to retract when unlocking, so that the bolt of the lock body is driven to extend through the lock core, the plectrum of the lock core is required to rotate 2 circles or even more than 2 circles to realize the complete extension or retraction of the lock bolt, the unlocking execution speed is not satisfactory for some times, and the dial wheel of the lock core is required to rotate several circles, so that the handle of the electronic lock is generally not in a long handle shape, and is not suitable for some times in the inherent visual sense of the lock in the market; certainly still some other electronic lock producers adopt the motor direct drive lock core to rotate, and then drive the flexible scheme of lock body spring bolt, but the defect of this type of scheme is bigger: the motor is burdened greatly, the power consumption is large when the motor rotates, and the like due to the problem of the cooperation between the door and the lock.
