Abstract

The invention discloses a safety catch of a lock cylinder. The safety catch of the lock cylinder comprises a safety catch (45), a safety catch sliding cavity (42) and a restoring spring (43), wherein the safety catch sliding cavity (42) is arranged at the front end of the lock cylinder (41) which is internally provided with the safety catch (45); a spring fixing groove (44) is arranged at the upper end of the safety catch (45); the restoring spring (43) is arranged inside the spring fixing groove (44); the upper end of the restoring spring (43) is contacted with the upper inner wall of the sliding cavity of the safety catch (42); the lower end of the safety catch (45) is contacted with the bottom side face of a key hole (46); and the upper part of the safety catch (45) is of a cuboid shape and the bottom is the combination body of three trapeziums. When a key is inserted into the key hole (46), the bottom end of the safety catch (45) is inserted into the safety catch bayonet (31) of the key under the effect of the restoring spring (43) to close the key hole (46) at the front and improve the safety of locksets.

Description

The lock core lock

Technical field

The invention belongs to mechanical lockset, particularly relate to a kind of lock core lock.

Background technology

In the mechanical lock; The keyhole of lock core all is open except magnetic lock; This provides great facility to technology unlocking, and one Chinese patent application 200910193657.3 and 201110376353.8 discloses the structure of relevant interlocking lock core, and the technology of this lock core sliding shoe is not given full play to; The not enough yardstick of sealing keyhole pellet shot from a slingshot also has bigger entering space.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of lock core lock.

Realize the technical scheme that the present invention adopted: a kind of lock core lock comprises lock (45), lock sliding cavity (42), back-moving spring (43); Said insurance sliding cavity (42) is positioned at the front end of lock core (41), embedded with safety bolt (45); Said lock (45) upper end is provided with spring holddown groove (44); The built-in back-moving spring of said spring holddown groove (44) (43); Said back-moving spring (43) upper end contacts with insurance sliding cavity (42) upper inner wall; Said lock (45) lower end contacts with keyhole (46) bottom side.

Lock (45) upper part is a cuboid, and the bottom is divided into the assembly of three trapezoidal shapes.

The specific embodiment

With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, the structure of lock core lock, a kind of lock core lock comprises lock (45), lock sliding cavity (42), back-moving spring (43); Said insurance sliding cavity (42) is positioned at the front end of lock core (41), embedded with safety bolt (45); Said lock (45) upper end is provided with spring holddown groove (44); The built-in back-moving spring of said spring holddown groove (44) (43); Said back-moving spring (43) upper end contacts with insurance sliding cavity (42) upper inner wall; Said lock (45) lower end contacts with keyhole (46) bottom side.

With reference to figure 5, Fig. 6, lock (45) upper part is a cuboid, and the bottom is divided into the assembly of three trapezoidal shapes.

Operating principle of the present invention: after key injected keyhole (46), lock (45) was under the effect of back-moving spring (43), and lock bayonet socket (31) lining of key is injected in the lower end; The positive complete closed of keyhole (46); Technology unlocking can't be estimated carry out carrying out with straight line, when technology unlocking was dialled lock (45) get up, lock (45) can block lock core sliding shoe (4) slip and reset; Each parts of lock core just can't run to the open position of setting, so reach purpose of safety.

Claims
