Abstract
Description
- The present invention relates to a lock core configuration of a lockset, especially to a lock core structure with an anti-theft function.
- The existing conventional anti-theft lock basically comprises a lock seat provided on a lockset, and a single lock core is then provided within the lock seat. The purpose of unlocking is achieved by inserting a corresponding key into a key hole of the lock core and rotating the same to release a lockout function between a lock pin and the lock seat within the lock core structure. However, no matter how complicated the structure of the lock core is, the lock core is of a simplified design which can enable thieves to easily unlock with picking tools, such as inserting a probe into the key hole of the lock core by means of exploration and gradually unlocking the lock in an exploring manner, and finally, the thieves can successfully unlock in an extremely short time to achieve the purpose of stealing.
- For that reason, the inventor is engaged in designing an anti-theft lock core that cannot be unlocked by thieves with any kind of picking tools to achieve the purpose of stealing. Finally, the present invention is brought forth after numerous researches and experiments.
- The main purpose of the present invention is to provide a lock core structure of a lockset, which makes thieves unable to unlock with picking tools, so as to realize an anti-theft function.
- For the accomplishment of the aforementioned purpose, the present invention provides thefollowing solution:
- A lock core configuration of a lockset, comprising:
- a hollow cylinder providedon the entity of the lockset and having an inner chamber with a circular cross section;
- a cylindrical upper axially rotating body and a cylindrical lower axially rotating body which are separated from each other, can be provided in said inner chamber, and are capable of rotating; and
- a blocking body provided between the upper and lower axially rotating bodies and firmly fixed within the inner chamber of an outer cylinder, without rotating.
- If said structure is adopted, when an unlocking attempt is made by a thief with picking tools, the thief can at most effect a decoding unlocking procedure on the upper axially rotating body. Due to a non-rotatable situation of the blocking body, it is impossible to carry out a rotating unlocking procedure on the lower axially rotating body with the picking tools, which finally would stop the theft.
