Description

井字形锁芯及配套钥匙
技术领域
本实用新型涉及一种井字形锁芯，尤其是锁芯钥匙四个面长槽各异，钥匙和锁芯认面相配结构的锁芯。
技术背景
目前，公知的井字形锁芯四个面长槽是单一互通的钥匙对准任何一面都能插入，其锁芯互开率高，安全保险性能低，不能很好的起到保险防盗作用。
发明内容
为了克服现有的井字形锁芯互开率高的技术不足，本实用新型提供一种井字形锁芯及配套钥匙，该井字形锁芯及配套钥匙不仅能将锁芯四个面长槽设成各异，钥匙与锁芯只能认面插入，而且将双排弹子孔设计成交错排列，大大提高保险性能。
本实用新型的目的是提供一种井字形锁芯及配套钥匙，在圆形锁芯中心设成井字形长槽，锁芯四个面各面长槽各异，配入相对应的钥匙，锁芯四面设有双排交错的若干个弹子孔供放弹子之用，弹子数量多，锁芯外边套进锁芯外壳，锁芯可灵活的在外壳内旋转自如，结构简单，使用方便。
本实用新型的有益效果是井字形锁芯四个面长槽各异，锁芯与钥匙认面插入开锁，互开率极低，安全保险性能高，大大提高了防盗作用，结构简单。
附图说明：
下面结合附图和实例对本实用新型进一步说明：
图1是本实用新型结构图
图2是本实用新型剖视图
图3是本实用新型正面图
在图中，1、锁芯；2、锁芯长槽；3、弹子孔；4、钥匙；5、锁芯壳体。
具体实施方法：
在图1中，锁芯(1)中心设有井字形锁芯长槽(2)，锁芯(1)四个面各设有双排互交错弹子孔(3)，锁芯长槽(2)配入钥匙(4)，锁芯壳体(5)套住锁芯(1)，锁芯(1)在锁芯壳体(5)中旋转灵活自如。
