Description
本发明涉及锁芯,特别是涉及一种加工和装配方便便捷,并可提升安全性能的叠片式锁芯。
锁芯是锁的核心部件,用于和钥匙相匹配,形成开锁密码,从而实现上锁或开锁。传统的锁芯均为由弹簧控制的弹子锁芯,其主要由下弹子、平头弹子(也称上弹子)、弹簧、锁壳及内胆构成。这类锁芯的加工装配较为复杂,其需分别在每个内胆及锁壳上单独加工弹子孔,并须使用车床、钻床、冲床等多种设备进行加工,因此加工工序复杂,加工时间长,加工及装配效率低下。此外,传统的弹簧弹子锁芯的弹子数量有限,因此,其不同弹子组合而形成的开锁密码的复杂度也有限,容易被破解,窃盗者很容易根据弹簧弹子的工作原理进行撬盗或暴力拆除。因此,现有的这种弹簧弹子锁芯,不仅加工不便,而且安全性还有待提高。
本发明旨在解决上述问题,而提供一种加工和装配方便便捷,可提高加工效率,降低生产成本,并可提高安全性能的叠片式锁芯。
为实现上述目的,本发明提供了一种叠片式锁芯,其特征在于,该叠片式锁芯包括锁芯套、多个叠片及多个片状弹子,所述锁芯套的内壁上对称设有弹子槽,锁芯套内沿轴向设有多个依次叠合并固定为一体的叠片,每个叠片由两片弓形半叠片构成,所述弹子分别设置在每两片弓形半叠片之间,并可在所述锁芯套的的弹子槽内移动,在所述弹子上设有可插设钥匙的钥匙孔及形成开锁密码的凸起,多片叠片及弹子叠合后,其钥匙孔对合形成锁孔,且当无钥或与所述凸起不匹配的钥匙插入所述锁孔内时,所述弹子的一端位于所述弹子槽内而卡住所述锁芯套,使叠片式锁芯无法转动;当与所述凸起相匹配的配套钥匙插入所述锁孔内时,所述弹子在钥匙的带动下径向移动,从而使得所述弹子与叠片形成可转动的圆柱体,通过旋转即可开锁。
所述凸起是由所述钥匙孔的一侧向内凸起而形成,且多个叠片上的多个凸起距锁芯套的中心轴线为非等间距排列。
所述弹子为矩形片状体,其长度与所述叠片的弓形弦长相一致。
在所述多个叠片之间间隔地设有若干个阻止外力拉出所述叠片用的圆形分隔片,在该分隔片上设有与所述钥匙孔相对应的通孔。
所述分隔片的直径大于所述弓形半叠片的弓形弦长。
所述锁芯套由多个锁芯套片依次叠合并固定为一体而形成,在与所述叠片和分隔片相对应的位置的锁芯套片上设有与所述叠片或分隔片尺寸相匹配的圆孔,在所述圆孔内壁上对称设有矩形槽,多个锁芯套片叠合后,其圆孔对合形成可装设所述叠片及分隔片的锁芯腔,其矩形槽对合形成所述弹子槽。
所述分隔片与所述叠片铆接成一体后装设于所述锁芯腔内。
所述锁芯套片依次叠合并铆接成一体而形成锁芯套。
本发明的有益贡献在于,其有效解决了传统弹簧弹子所存在的安全性和加工装配效率低等问题。本发明通过设置多个相互叠合的弹子及叠片,利用弹子上不同排列的凸起而形成钥匙开锁的密码,使得只有与凸起相匹配的钥匙才能带动弹子与叠片形成一个可以转动的圆柱体进行旋转开锁。由于弹子呈片状,其可通过冲床批量加工,因此可大幅降低生产成本,且加工方便,装配简单。本发明可根据需要而叠合足够多数量的弹子,从而可大大增加密码复杂度,加强锁芯的安全性。此外,本发明还通过在叠片之间设置尺寸更大的分隔片及与之匹配的叠片锁芯套,使得分隔片可阻止其内侧的弹子及叠片无法被取出,进一步加强了锁芯的安全性。本发明不仅具有加工方便,装配简单等特点,还具有安全性高的特点。

下列实施例是对本发明的进一步解释和补充,对本发明不构成任何限制。
如图1~图6所示,本发明的叠片式锁芯包括锁芯套10、多个叠片30、多个片状弹子20及圆形分隔片40。在所述弹子20上设有形成密码的凸起22,本发明通过将多个弹子20相互叠合,从而可形成复杂度更高的开锁密码,大大提升锁芯的安全。此外,本发明通过叠片30与分隔片40交叉叠合,从而利用尺寸更大的分隔片40限制其内侧的叠片30无法被抽出,进一步加强锁芯的安全性,防止被撬盗。本发明不仅具有安全性高,而且加工方便。
更具体地,如图2所示,每个叠片30由两片相互对称的弓形半叠片31构成。所述弹子20为矩形片状体,其长度与所述弓形半叠片31的弓形弦长相一致。所述弹子20分别设于每两片弓形半叠片31之间,每两个弓形半叠片31与一个弹子20可对合形成一个圆形。在每个弹子20上设有可插设钥匙的钥匙孔21及形成开锁密码的凸起22,所述凸起22由所述钥匙孔21的一侧向内凸起22而形成。当多个弹子20相互叠合时,其钥匙孔21相对合形成锁孔,所述凸起22的排列则与开锁钥匙上的锁槽形状相对应。为增强安全性,多个弹子20上的多个凸起22距弹子20的中心轴线为非等间距排列。在所述弓形半叠片31上分别设有位置相对应的连接孔,其用于将各叠片相固定。本实施例中,全部叠片30通过铆接而固定为一体。
如图1所示,所述锁芯套10用于装设所述叠片30及弹子20。在所述锁芯套10的内壁上对称设有弹子槽11,该弹子槽11沿其轴向延伸,其宽度与所述弹子20的宽度相匹配。当所述弹子20及叠片30置入所述锁芯套10内时,所述弹子20便可沿其径向在弹子槽11内移动。当锁芯安装时,若其锁孔呈垂直状态,所述弹子20则在重力作用下而部分位于弹子槽11内,其可卡住所述锁芯套10,使之无法转动而开锁。若锁孔呈水平状态,当匹配钥匙拔出时,所述弹子20也会在钥匙的带动下而部分位于弹子槽11内,进而卡住所述锁芯套10而无法开锁。只有当与所述凸起22相匹配的钥匙插入时,所述凸起22才会在钥匙的带动下与所述叠片30形成圆柱形,此时弹子20无法卡住锁芯套10,便可转动开锁。
如图1所示,为进一步加强锁芯安全性,防止撬盗者破坏锁芯套10而将叠片30及弹子20整体抽出,可在各叠片30之间间隔设置圆形分隔片40。如图4所示,所述分隔片40可由工具钢等高强度、高硬度钢制成,其直径大于所述弓形半叠片31的弓形弦长。在所述分隔片40上设有矩形通孔41,该通孔41位置与所述钥匙孔21相对应,其大小以不妨碍钥匙的抽插为准,其可与所述钥匙孔21的大小相同,也可略大于所述钥匙孔21。在所述通孔41的两侧分别设有圆形连接孔,其与所述弓形半叠片31上的连接孔位置相对应,使得分隔片40与前后的叠片30可通过连接孔而定位连接为一体。所述分隔片40的数量可视锁芯所需达到的复杂度而设置,本实施例中,如图5所示,每三个叠片30之间设有一个分隔片40,且所述分隔片40的尺寸既可相同,也可不同,只要分隔片40
的尺寸不与叠片30的尺寸完全一致,其便可起到一定的阻止作用。
由于分隔片40的尺寸与所述叠片30的尺寸不相一致,为便于装配,在图1、图6所示的实施例中,所述锁芯套10也设置成叠片状结构。所述锁芯套10由多个锁芯套片12叠合组成,每个锁芯套片12上设有圆孔121,其圆孔121的大小分别与所述叠片30或分隔片40的尺寸相一致,从而使得锁芯套片12叠合后其圆孔121相对合形成阶孔,并与所述叠片30与分隔片40的排列相一致,即每3个与叠片30相一致的锁芯套片12叠合一个与分隔片40相一致的锁芯套片12。在所述圆孔121上分别对称设有矩形槽,当多个锁芯套片12相叠合时,所述矩形槽对合成所述弹子槽11。本实施例中,所述锁芯套片12
通过铆钉铆接成一体。
与传统锁芯不同的是,本发明的锁芯在加工时,先批量加工出叠片30、弹子20、锁芯套片12及分隔片40。由于单个的叠片30、弹子20、锁芯套片12、分隔片40结构简单,因此加工方便。装配时,先根据锁芯所需达到的安全性而设计好叠片30与分隔片40的排列规律,然后先将位于端部的单个叠片30或分隔片40装入与之匹配的锁芯套片12内,之后再叠合一个锁芯套片12及弹子20和叠片30或分隔片40,依次类推,待叠合足够多的叠片30及分隔片40后,利用铆钉将叠片30与分隔片40固接为一体,并铆钉将锁芯套片12固接为一体,藉此,便可将叠片30与弹子20及分隔片40置于锁芯套10内,并且由于分隔片40与叠片30的尺寸不同,较大的分隔片40便会限制其内侧的叠片30及弹子20无法被抽取出,即使最外侧的锁芯套10被工具破坏,其也无法将内侧的叠片30及弹子20取出,其同样无法开锁。为加强锁芯套片12之间连接的牢固性,可在锁芯套10的外侧壁上用激光焊将其焊接在一起。利用铆钉将锁芯套片12固接为一体时,可采用沉头的方式,将铆钉头部分嵌设在锁芯套片12内,同样可加强锁芯套片12之间的牢固性。
当叠片30、弹子20及分隔片40依次叠合并装设于锁芯套10内而形成叠片式锁芯时,为从整体上加强锁芯的强度,可在锁芯的端部设置各种公知结构的保护盖。本发明的锁芯即可用作单头锁中,也可用在双头锁中,用在双头锁中时,两个锁芯之间的连接可参考公知技术。
尽管通过以上实施例对本发明进行了揭示,但是本发明的范围并不局限于此,在不偏离本发明构思的条件下,以上各构件可用所属技术领域人员了解的相似或等同元件来替换。
