Anti-knocking lock
The invention discloses an anti-knocking lock which comprises a lock shell, and a spring bolt, a stop block, a power device, a cam, a sliding rod, a first reset piece and a second reset piece which are arranged in the lock shell, the lock shell is provided with a lock hole; the middle of the lock tongue is rotationally connected with the lock shell, and one end of the lock tongue is telescopically matched at the lock hole; the middle of the check block is rotationally connected with the lock shell. The power device is in transmission connection with the cam for driving the cam to rotate; the cam and the sliding rod are oppositely arranged, and the sliding rod moves along with rotation of the cam. The sliding rod is matched with the lock shell in a sliding connection mode and points to the lock hole, and the check block rotates along with movement of the sliding rod so as to limit or avoid rotation of the spring bolt. The first reset piece is used for providing elastic force to reset the spring bolt to the upper locking state, and one end of the spring bolt extends out of the lock hole in the upper locking state. The second reset piece is used for providing elastic force to reset the sliding rod to the upper locking state, and in the upper locking state, the sliding rod drives the stop block to limit rotation of the spring bolt. The anti-knock unlocking device has the anti-knock unlocking function, and meanwhile the structure is simplified, and the cost is reduced.
本发明公开一种防敲击锁具，包括锁壳，以及设在锁壳内的锁舌、挡块、动力装置、凸轮、滑杆、第一复位件和第二复位件；锁壳设有锁孔；锁舌的中部与锁壳转动连接，其一端在锁孔处伸缩配合；挡块的中部与锁壳转动连接；动力装置与凸轮传动连接，用于驱动凸轮转动；凸轮与滑杆相对设置，滑杆随着凸轮的转动而移动；滑杆与锁壳滑接配合并指向锁孔，挡块随着滑杆的移动而转动，以实现限位或让位锁舌的转动；第一复位件用于提供弹力使得锁舌向上锁状态复位，上锁状态时锁舌的一端伸出锁孔；第二复位件用于提供弹力使得滑杆向上锁状态复位，上锁状态时滑杆带动挡块限位锁舌的转动。本发明在具备防敲击开锁功能的同时，实现简化结构、降低成本。
