Door lock unlocking handle device
The invention discloses a door lock unlocking handle device which comprises a lock box, a handle and a lock head, the handle and the lock head are arranged on the lock box, a lock cylinder is installed in the lock head, the lock cylinder is coaxially sleeved with a cam, and the cam synchronously rotates along with the lock cylinder; a pressing rod assembly located below the cam is further arranged in the lock box, the pressing rod assembly comprises an outer frame fixed in the lock box and a pressing rod installed in the outer frame, and the pressing rod slides up and down in the outer frame. A shifting fork and an unlocking disc are arranged below the pressing rod assembly, a second torsional spring is arranged on the shifting fork, one end of the second torsional spring is fixed in the lock box, and the other end of the second torsional spring is connected with the shifting fork. And the unlocking disc is connected with the handle through the mandrel. Lever structures are formed at the two ends of the shifting fork, in the locking state, one end of the shifting fork abuts against and makes contact with the pressing rod, the other end of the shifting fork abuts against and makes contact with the unlocking disc, the contact point is a dead point, and the handle cannot rotate. When unlocking is conducted, the cam rotates along with the lock cylinder and presses the pressing rod downwards, the pressing rod presses the shifting fork downwards to remove the dead point, the unlocking disc restores motion, and the handle is rotated to conduct unlocking.
本发明公开了一种门锁解锁把手装置，包括锁盒、设于锁盒上的把手和锁头，锁头内安装有锁芯，锁芯上同轴套设有凸轮，凸轮随锁芯同步转动；锁盒内还设有位于凸轮下方的压杆组件，压杆组件包括固定于锁盒内的外框和安装于外框内的压杆，压杆在外框内上下滑动；压杆组件下方设有拨叉和解锁盘，拨叉上设有第二扭簧，第二扭簧一端固定于锁盒内，另一端与拨叉连接；解锁盘通过芯轴与把手连接。拨叉的两端形成杠杆结构，锁定状态下，拨叉一端与压杆抵靠接触，拨叉另一端与解锁盘之间抵靠接触且接触点为死点，把手无法转动；进行解锁时，凸轮随锁芯转动并将压杆下压，压杆下压拨叉解除死点，使解锁盘恢复运动，转动把手进行解锁。
