A lock cylinder anti-riot protection device

Abstract

The invention provides a cylinder anti-forced-opening protector comprising a cylinder assembly, a cylinder collar, an inner anti-drill cover, an outer anti-pick cover, a rear pin, and a front pin. The lock collar enclosures the cylinder assembly. The outer anti-pick cover covers the front end of the cylinder collar and provided with an inner anti-drill cover mounting hole. The inner anti-drill cover is movably disposed in the inner anti-drill cover mounting hole and provided with a key hole matching with a lock hole of the cylinder assembly. The cylinder assembly, the inner anti-drill cover and the outer anti-pick cover are arranged in a coaxial and concentric manner. The rear pin sequentially passes the cylinder collar and the cylinder assembly to fixedly rivet the rear end of the cylinder collar and the rear end of the cylinder assembly. The front pin sequentially passes the outer anti-pick cover, the cylinder collar and the cylinder assembly to fixedly rivet the front end of the outer anti-pick cover, the front end of the cylinder collar and the front end of the cylinder assembly. The cylinder anti-forced-opening protector can prevent the cylinder from being twisted off by a lock twister and prevent the cylinder from being picked open with forced opening tools, thus safety of the lock is improved greatly.
