一种挂锁
本技术涉及机械锁,特别是挂锁。
技术介绍
锁具在日常生活中有着广泛的应用。现有的锁具大概分为两大类:机械锁和电子锁,机械锁又分为普通机械锁和密码机械锁。普通机械锁制作成本较低,应用最广泛,但其保密性较差,钥匙容易被复制,钥匙又厚又重、出门随身佩带很不方便。另外,机械锁要更换时,通常要整体更换或更换锁胆,比较麻烦。密码机械锁无需佩带钥匙,但要记住密码,现今人们要记的密码太多,容易混乱。电子锁的保密性较机械锁高,但其需要设置专门的解码电路,锁的制造较为复杂,成本亦高,由于采用大规模集成电路,容易出现故障。
技术实现思路
本技术的目的是提出一种挂锁,其采用密码块结构,具有薄的卡片式钥匙,方便携带,更重要的是换锁不需要更换锁胆,只更换密码块即可,而且更换密码块十分容易。本技术的目的可通过如下技术方案来实现。一种挂锁,包括有锁体和锁舌,锁体的前部左右两侧分别开有锁孔和锁舌孔,锁舌弹簧和钩形锁舌的一端置于锁舌孔内,锁舌的另一端可插入锁孔内,锁舌近锁体处具有锁舌卡口,当将锁舌的两端分别位于锁孔和锁舌孔内时、2个锁舌卡口分别位于锁孔和锁舌孔内;锁体的中部开有密码块槽,一密码块置于密码块槽内,密码块槽的横断面与密码块相当。所述密码块为矩形板结构、其配合钻孔卡片使用,密码块的内部具有滑块并分布有若干弹子对、其前端具有锁销,密码块内具有卡片插槽,钻孔卡片上分布有若干卡片孔,当将钻孔卡片插入卡片插槽内、其卡片孔与滑块内的全部弹子对相匹配时,可向前推动滑块进而驱动锁销向 ...
