Abstract
The invention relates to an anti-burglary screw lock, wherein a solid screw pivot lock cylinder is matched and connected with a hollow screw pivot key. The diameter of the solid screw pivot lock cylinder is identical to that of the hollow screw pivot key. The spatial three-dimensional structures of the solid screw pivot lock cylinder and the hollow screw pivot key are completely complemented. A plurality of grooves matched with balls are arranged on the inner surface of the hollow screw pivot key and are matched with balls. The balls are randomly distributed on the screw structure. The inner balls pass through the circle center of the solid screw pivot lock cylinder. The anti-burglary screw lock provided by the invention has the technical effects that the anti-burglary screw lock is simple in structure, the structure of conventional locksets is changed, the lock is effectively prevented from being unlocked by illegal persons with iron wires or universal locks, and the safety of the lockset is improved.
Description
Technical field
The present invention relates to a kind of theftproof lock, relate in particular to a kind of theft-protected screw lock.
Background technology
Lock is a kind of utensil with the anti-theft protection property of locking a door commonly used in the life, in the very long years, along with the continuous development of human civilization; The purposes of lock constantly increases, and the scope of application is wide more, from ancient times to the present; The locking industry of China is all very flourishing, has produced many creativity and innovations.Lockset develops into present various dissimilar intelligence lock by initial wood lock, three springs lock, blade lock.At present, what use always in people's life also all is the lockset that adopts the sub mode of unblanking of lock, in order to strengthen anti-theft effect; Locksmiths create various lockset; Though lock structure is different, the mode of unblanking is similar, and lock all is to adopt linear structure; This mode of unblanking is prone to adopted iron wire and unlocked by universal key by illegal molecule, and safety factor is not high.
Summary of the invention
The object of the present invention is to provide a kind of theft-protected screw lock, this spiral lock solved existing lockset be prone to by master key or other unlocking tool open maybe, thoroughly changed the mode of unblanking, anti-theft capability is strong.
The present invention realizes like this; It comprises solid borded pile lock core and cored screw post key; It is characterized in that the solid borded pile lock core cored screw post key that is connected; The diameter of solid borded pile lock core is identical with the diameter of cored screw post key, and the space multistory structure of solid borded pile lock core and cored screw post key is complementary fully, and the inner surface of described cored screw post key is provided with several grooves and matches with pellet shot from a slingshot; Pellet shot from a slingshot arbitrarily is distributed on the helical structure, and interior pellet shot from a slingshot is the center of circle through solid borded pile lock core all.
The two ends of said solid borded pile lock core are open.Disconnected key or foreign matter exist in the solid borded pile lock core and all can screw out from the other end.
Technique effect of the present invention is: simple in structure, changed the structure of conventional lock, and prevented that effectively illegal molecule from unblanking with iron wire or omnipotent lock, improve lockset safety.

Solid borded pile lock core 2, cored screw post key 3, pellet shot from a slingshot 4, groove in the drawings, 1.
The specific embodiment
Like Fig. 1, shown in Figure 2; The present invention realizes like this; It comprises solid borded pile lock core 1 and cored screw post key 2; The solid borded pile lock core 1 cored screw post key 2 that is connected, the diameter of solid borded pile lock core 1 is identical with the diameter of cored screw post key 2, and the space multistory structure of solid borded pile lock core 1 and cored screw post key 2 is complementary fully; The inner surface of described cored screw post key 2 is provided with several grooves 4 and matches with pellet shot from a slingshot 3, and interior pellet shot from a slingshot 3 is the center of circle through solid borded pile lock core 1 all.The two ends of said solid borded pile lock core 1 are open.Disconnected key or foreign matter exist in the solid borded pile lock core and all can screw out from the other end.
Workman's bitting in order to prevent to fit up, this spiral lock increases by one secondary key, and this pair key can use to the workman when fitting up; This pair key is identical with cored screw post key structure, but length is shorter than cored screw post key, before dispatching from the factory lock core the inside one pellet shot from a slingshot uses the supporting spring picking-up to be opening; Cored screw post key is opened the back supporting spring and is removed; This pellet shot from a slingshot plays a role, and secondary key can not get at this pellet shot from a slingshot, and secondary key lost efficacy.
Claims (3)
1. a theft-protected screw is locked; It comprises solid borded pile lock core and cored screw post key; It is characterized in that the solid borded pile lock core cored screw post key that is connected; The diameter of solid borded pile lock core is identical with the diameter of cored screw post key, and the space multistory structure of solid borded pile lock core and cored screw post key is complementary fully, and the inner surface of described cored screw post key is provided with several grooves and matches with pellet shot from a slingshot; Pellet shot from a slingshot arbitrarily is distributed on the helical structure, and interior pellet shot from a slingshot is the center of circle through solid borded pile lock core all.
2. theft-protected screw lock according to claim 1, the two ends that it is characterized in that said solid borded pile lock core are open.
3. theft-protected screw lock according to claim 1 is characterized in that the identical secondary key of cored screw post key structure that is set forth in, and said secondary key is shorter in length than cored screw post key.
