Pin tumbler lock with hidden axial pin

Abstract

The invention relates to a pin tumbler lock with a hidden axial pin, which has the design keys that the inner ends of an outer lock core and an inner lock core are provided with an outer lock core axial pin hole and an inner lock core axial pin hole respectively; the outer lock core axial pin hole and the inner lock core axial pin hole are not arranged in the key hole of the inner lock core; both the inner lock core axial pin hole and the outer lock core axial pin hole are provided with axial pins and axial reset springs; the axial reset springs enable the axial pins in the inner lock core axial pin hole and the outer lock core axial pin hole to be propped against each other; a push rod is arranged on the axial pin in the inner lock core axial pin hole; a sliding hole matched with the push rod in a sliding way is arranged in the inner lock core and communicated with the inner lock core axial pin hole and the key hole; and the end part of the push rod is arranged in the key hole. The pin tumbler lock has reasonable structural design and high security, is difficult to unlock with skills, has wide variable range, low interchangeability and high safety, and is suitable for serving as the pin tumbler lock or the structure improvement of similar products.

Description

technical field [0001] The invention relates to a pin lock, which is a pin lock with a concealed axial pin. Background technique [0002] The pin lock is the most commonly used lock. Its working principle is mainly to set cylindrical pins of different lengths in the pin holes of the lock cylinder. When the key is inserted into the lock core, the teeth of the key will lift the pins to a certain Height plane, so as to realize unlocking. Existing tumbler lock, because structure is simple, the effect of its anti-technical unlocking is relatively poor; Lock", which includes a lock cylinder, a lock cylinder shell, a vertical pin and a locking actuator. A rotating body is coaxially arranged at the front end of the lock cylinder and the lock housing; a fixed body is arranged in the middle of the front end of the rotating body; To the interior of the rotating body, a horizontal pin hole is arranged at the front end of the lock groove. The horizontal pin hole connects the rotating b...
