Abstract

The utility model discloses a lock and particularly relates to a two-side blade C-level lock cylinder. The lock cylinder comprises a cylinder body and a first key and a second key which are matched with the cylinder body. Each of the first key and the second key comprises a first key rod and a second key rod. A first key hole and a second key hole are formed in the tops of the first key rod and the second key rod respectively and are matched with the cylinder body and are accordant in structure. A key insertion hole is formed in the cylinder body, a pin tumbler is arranged on the inner side of the cylinder body, and a pin tumbler hole is formed in the front end of the first key and is matched with the pin tumbler. According to the lock cylinder, a key cannot be used even if the key is replicated, so that the lock cylinder is high in safety.

Description

Two-sided blade C level lock core

Technical field

The utility model relates to lock technology field, particularly relates to a kind of two-sided blade C level lock core.

Background technology

As everyone knows, lockset has referred to the utensil of sealing process, is extensively present in daily life; The key that existing lockset generally includes lock core and matches with lock core, before use, lock core and key need to be given installer conventionally to complete installation process, in this course, because key has reproducibility, inevitably exist some installer for private interests, key is copied, have so certain potential safety hazard.

Utility model content

For solving the problems of the technologies described above, the utility model provides timely key in a kind of installation process to be replicated also and cannot to use, the two-sided blade C level lock core that safety is higher.

Two-sided blade C level lock core of the present utility model, the first key and the second key that comprise lock core and match with described lock core, described the first key and the second key comprise respectively the first key bar and the second key bar, the end face of described the first key bar and the second key bar is respectively arranged with the first keyhole and the second keyhole, described the first keyhole and the second keyhole all match with described lock core, and described the first keyhole is consistent with the second keyhole structure, on described lock core, be provided with key hole, the inner side of described lock core is provided with hoodle, the front end of described the first key is also provided with hoodle hole, described hoodle matches with described hoodle hole.

Further, the bottom surface of described the first key bar and the second key bar is also respectively arranged with three-keyhole and four-keyhole, described the first keyhole and described three-keyhole are along described the first key bar axis of orientation symmetry, and described the second keyhole and described four-keyhole are along described the second key bar axis of orientation symmetry.

Compared with prior art the beneficial effects of the utility model are: the first key and the second key that comprise lock core and match with lock core, the first key and the second key comprise respectively the first key bar and the second key bar, the end face of the first key bar and the second key bar is respectively arranged with the first keyhole and the second keyhole, the first keyhole and the second keyhole all match with lock core, and the first keyhole is consistent with the second keyhole structure, on lock core, be provided with key hole, the inner side of lock core is provided with hoodle, the front end of the first key is also provided with hoodle hole, hoodle matches with hoodle hole, in the time that the first key inserts, hoodle springs in the hoodle hole of the first key front end, and when rotation, hoodle can not fall down, and now the first key and the second key can be opened lock, when the second key insert first and rotating 360 degrees after be positioned at lock core inside front hoodle drop with key, at this moment, the first key just cannot be unblanked, and only has the second key just can opened lock, like this, in the time that lock is installed, can give installer's the first key, install rear use the second key and insert after use once, the first key ceases to be in force automatically, such lock core,, safety is higher for theftproof performance.

Fig. 2 is the structural representation of the first key in the utility model.

Fig. 3 is the structural representation of the second key in the utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

As shown in Figure 1 to Figure 3, two-sided blade C level lock core of the present utility model, the first key 4 that comprises lock core 2 and match with lock core and the second key 6, the first key 4 and the second key 6 comprise respectively the first key bar and the second key bar, the end face of the first key bar and the second key bar is respectively arranged with the first keyhole 7 and the second keyhole 8, the first keyhole 7 and the second keyhole 8 all match with lock core 2, and the first keyhole 7 is consistent with the second keyhole 8 structures, on lock core 2, be provided with key hole 3, the inner side of lock core 2 is provided with hoodle 1, the front end of the first key 4 is also provided with hoodle hole 5, hoodle 1 matches with hoodle hole 5, in the time that the first key inserts, hoodle springs in the hoodle hole of the first key front end, and when rotation, hoodle can not fall down, and now the first key and the second key can be opened lock, when the second key insert first and rotating 360 degrees after be positioned at lock core inside front hoodle drop with key, at this moment, the first key just cannot be unblanked, and only has the second key just can opened lock, like this, in the time that lock is installed, can give installer's the first key, install rear use the second key and insert after use once, the first key ceases to be in force automatically, such lock core,, safety is higher for theftproof performance.

Two-sided blade C level lock core of the present utility model, the bottom surface of the first key bar and the second key bar is also respectively arranged with three-keyhole and four-keyhole, the first keyhole and three-keyhole are along the first key bar axis of orientation symmetry, and the second keyhole and four-keyhole are along the second key bar axis of orientation symmetry; Like this, adopt two-sided key, thereby no matter use which face of key insert can, use more for convenience.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
