Description

Novel prevent disconnected auto-lock core

[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of locks, in particular to a novel anti-breaking self-locking lock cylinder.

[ background of the invention ]

Most common bilateral lock cylinders in the market can be unlocked by inserting keys from the inside and the outside of the door, when a lawbreaker forcibly breaks off the lock cylinders by using tools outside the door, the common lock shell is broken at an open slot, a pulling lug or a rotating key connected with the pulling lug is exposed outside, and the lawbreaker can unlock by rotating the rotating key or the pulling lug through various tools, which is also one of the means of violent opening the door by a plurality of thieves; under the condition, once the front half part of the lock cylinder is broken by a lawless person, a user cannot open the lock cylinder to open the door on the other side of the lock cylinder, namely the room, by using a correct key, so that the user cannot open the door in the room to save self and needs to ask for help of a professional unlocking maker, which brings great trouble to the user and brings great potential safety hazards to lives and property.

Although a lock core structure capable of partially preventing the phenomenon also appears in the market, the lock core has the defects of high production difficulty, more accessories, difficult installation and the like, and for the defects, the applicant has disclosed a breaking-proof self-locking lock core, which is disclosed in the Chinese utility model patent with the publication number of CN211776558U, an arc-shaped sliding groove positioned outside the first longitudinal hole is formed in the concave side end surface of an inner clutch piece, and when the lock core enters a breaking-proof self-locking state, the lower end of the steel ball passes through the second longitudinal hole, enters the arc-shaped sliding groove and abuts against the upper end surface of the clutch limiting ball. The steel balls have larger rotating space in the arc-shaped sliding groove, so that the outer clutch piece and the inner clutch piece can be effectively prevented from being clamped by the steel balls, and the smoothness of relative rotation between the outer clutch piece and the inner clutch piece is ensured. When the applicant tests for many times, the applicant finds that the action among all the parts of the rotating inner clutch member is smooth when the rotating inner clutch member enters the anti-breaking self-locking state, but the clutch limiting ball slides out of the first longitudinal hole and partially enters the arc-shaped sliding groove when the inner clutch member rotates to 90-270 degrees, and the clutch limiting ball has the probability that the clutch limiting ball does not completely enter the first longitudinal hole and collides or is stuck with the steel ball when the inner clutch member 52 rotates to-90 degrees; therefore, the applicant carries out further structural optimization promotion on the product structure aiming at the problem in the invention creation.

In addition, the outer rotating key of the Chinese utility model can always keep linkage with the pulling under the action of the rotating key spring, and the market has the requirement that the outer rotating key and the pulling are not linked when partial customers do not insert keys, so that the applicant also carries out further structure optimization and promotion on the product structure aiming at the problem in the invention creation.
