The invention discloses a bottom-opening password padlock capable of preventing knocking opening. Comprising a lock body shell provided with a lock ring hole communicated with an inner cavity, a U-shaped lock ring, a code wheel set installed on the lock body shell and a lock brake installed in the lock body shell in a sliding mode. The control panel is rotationally installed in the lock body shell through a rotating shaft, the control panel reset elastic piece provides elastic holding force for the control panel to keep the contact control arm and inner wheels of the password wheel sets to make close contact, the two ends of a lock ring with the side wall provided with a clamping groove structure can be inserted into the lock body shell through lock ring holes, and a lock brake can be inserted into the clamping groove structure of the lock ring. The lock body shell is provided with a window allowing code marks on the code wheel set to be exposed out, and the positions, located on the two sides of the rotating shaft, of the control panel are provided with an insertion stop arm capable of preventing the control panel from being separated from the clamping groove structure on the lock ring and a contact control arm tightly abutting against the eccentric outer circumferential face of each inner wheel of the code wheel set respectively. And the potential risk of self-unlocking when the lock body is vibrated is avoided.
本发明公开了一种防敲击开启底开密码挂锁，包括设有与内腔连通的锁环孔的锁体外壳、呈U形的锁环、安装于锁体外壳上的密码轮组、滑动安装于锁体外壳内的锁闸、通过转轴转动安装于锁体外壳内的控制板和给控制板提供保持接触控制臂与密码轮组的内轮紧密接触的弹性保持力的控制板复位弹性件，侧壁设有卡槽结构的锁环两端能经锁环孔插入锁体外壳内，锁闸能插设于锁环的卡槽结构内，锁体外壳上设有供密码轮组上密码标识露出的开窗，控制板位于转轴两侧分别形成能阻止脱离锁环上卡槽结构的插接止挡臂和紧抵密码轮组的各个内轮偏心外圆周面的接触控制臂，本发明提高了控制板在锁体内的稳定性，避免了锁体受到震动时自行开锁的潜在风险。
