Door lock structure and cleaning machine applying door lock structure
The invention relates to a door lock structure and a cleaning machine applying the door lock structure. According to the door lock structure, when a door lock needs to be locked, the upper end of an ejector rod moves upwards and is buckled with a lock catch, a driving mechanism drives a locking plate to move backwards and drives a positioning needle to leave the position corresponding to the door opening state in a positioning groove, the restraining effect on the locking plate is cancelled, and the locking plate moves forwards under the action of a second elastic piece and limits the lock catch to prevent the lock catch from turning over, so that the locking state of the lock catch and a locking opening structure on the ejector rod is kept, and locking is completed; when unlocking is needed, the driving mechanism drives the locking plate to move backwards and drives the positioning pin to leave the position corresponding to the door closing state in the positioning groove and to be located at the position corresponding to the door closing state in the positioning groove, at the moment, a limiting structure on the locking plate cancels limiting of the lock catch, the lock catch turns over under the action of a first elastic piece, the lock opening structure of the ejector rod is allowed to be separated from the lock catch, at the moment, the ejector rod can move downwards to exit from a lock hole, and unlocking is completed; and the whole process is simple, reliable and convenient to implement.
本发明涉及一种门锁结构及应用有该门锁结构的清洗机，本发明的门锁在需要锁定时，顶杆上端向上移动并与锁扣相扣合，驱动机构驱动锁定板向后移动，驱动定位针在定位槽中离开对应开门状态的位置，取消对锁定板的约束作用，锁定板在第二弹性件作用下向前移动并对锁扣进行限位防止其翻转、而保持与顶杆上锁口结构的锁定状态，完成锁定；需要开锁时，驱动机构驱动锁定板向后移动，驱动定位针在定位槽中离开对应关门状态的位置而位于定位槽中对应关门状态的位置，此时，锁定板上的限位结构取消对锁扣限位，锁扣在第一弹性件作用下翻转，允许顶杆的锁口结构自锁扣中脱离，此时，顶杆可向下移动退出锁孔，完成开锁；整个过程简单可靠，便于实现。
