Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some, but not all, embodiments of the present utility model, and that all other embodiments obtained by persons of ordinary skill in the art without making inventive efforts are within the scope of this utility model.

Referring to the drawings, an automobile anti-theft lock with a split lock core in an embodiment of the present embodiment includes a lock rod 1, wherein a lock shell 2 is provided on the lock rod 1, and a lock core is provided in the lock shell.

The lock cylinder comprises a lock cylinder movable portion 4 and a lock cylinder fixed portion 5, the lock cylinder movable portion 4 is opposite to the lock cylinder fixed portion 5 and is located on the outer side, the lock cylinder movable portion 4 can rotate, an opening is formed in the lock cylinder movable portion, a lock groove is correspondingly formed in the lock cylinder fixed portion, the lock cylinder movable portion 4 is simple in overall structure relative to the lock cylinder and can be formed by machining stainless steel, drilling resistance is improved, when an electric drill bit contacts the lock cylinder movable portion 4, the lock cylinder movable portion 4 is stressed to rotate so that stress points are offset, the drill bit cannot be continuously damaged at the same point, damage difficulty is increased, a key stretches into and is inserted into the lock groove of the lock cylinder fixed portion 5 from the opening of the lock cylinder movable portion 4, the lock cylinder movable portion and the lock cylinder fixed portion rotate together with the key during unlocking, and the lock cylinder movable portion is long enough or the opening is narrow enough, and the drill bit cannot damage the lock cylinder fixed portion.

The following optimizations or further description can be made on the basis of the above embodiments, respectively.

Further, the anti-drilling layer 3 is arranged between the lock shell 2 and the lock cylinder moving part 4, the anti-drilling layer 3 can rotate, when the electric drill bit breaks the lock cylinder from the front, the anti-drilling layer 3 can rotate along with the lock cylinder moving part 4 through the connection relation to consume a part of acting force, when the electric drill bit breaks the lock cylinder moving part 4 from the side, the electric drill bit contacts with the anti-drilling layer 3 to enable the anti-drilling layer 3 to rotate under the stress, so that a part of acting force can be consumed, and the whole rotation of the drill bit can be influenced through friction.

Still further, be equipped with the spacing groove on the lock shell 2, lock core movable part 4 one side has spacing portion, spacing portion is in spacing inslot slip, spacing portion and spacing groove cooperation make lock core movable part 4 can be connected with lock shell 2 reliably, also can rotate.

The foregoing is a preferred embodiment of the present utility model, and it should be noted that the scope of the present utility model is not limited thereto. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the scope and spirit of the utility model as defined in the appended claims.
