Vane lock cylinder

Abstract

The invention discloses a vane lock cylinder. The vane lock cylinder comprises an outer lock liner, an inner lock liner, number slices and a lock pin. The inner lock liner is rotationally arranged in the outer lock liner. A plurality of slotted holes are formed in the inner lock liner in parallel in the axial direction and perpendicular to the axis. Each slotted hole is provided with a pair of number slices. Each number slice is provided with a keyhole, lock teeth and a reset spring making the number slice move towards the outside of the corresponding slotted hole. One side of each number slice is a lock edge. An unlocking groove is formed in each lock edge. A groove seam corresponding to the unlocking grooves is formed in the inner lock liner. A lock groove corresponding to the groove seam is formed in the outer lock liner. The lock pin is movably arranged in a cavity formed through the groove seam and the lock groove. The vane lock cylinder is characterized in that a lifting slice used for separating the two corresponding number slices is arranged in each pair of number slices. Each lifting slice is provided with a keyhole and an unlocking groove. Compared with the prior art, the vane lock cylinder is capable of effectively prolonging the service life of the number slices.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a blade lock cylinder. Background technique [0002] A lock is a fastener that is placed on an openable object and opened with a key or a password. Common locks can be divided into blade locks, pin locks and combination locks of blade locks and pin locks. From the perspective of technology itself, the blade lock is the lock with the highest performance in preventing key mutual opening and technical opening. [0003] In order to improve the anti-theft performance of the blade lock, people have designed various anti-theft blade lock cylinders. The blade lock cylinder with lock pins is one of them, and usually includes a lock outer tank, a lock inner tank rotatably arranged in the lock outer tank, Number plate and lock pin. A number of slots are arranged parallel to the axial direction and perpendicular to the axis on the lock liner, and a pair of number pieces are arranged in each...

Problems solved by technology

[0004] Compared with the combination of traditional pin locks and leaf locks and pin locks, although this leaf lock has better encryption, its number plate usually only has one reference point, and there is a risk of mutual opening and technical opening

Especially when the number of slots is small (less than six), some unscrupulous elements can still open the lock by moving the number to the appropriate position on both sides with special tools, and the safety factor still needs to be further improved.
