The invention relates to a blocking type cabin door opening position lock mechanism. The blocking type cabin door opening position lock mechanism is characterized in that an upper support and a lowersupport are fixedly connected to a cabin door structure, an upper crank is hinged to the upper support, a gas spring is hinged to the other end of the upper crank, the other end of the gas spring is hinged to the lower support, a cover plate is hinged to the lower support, one end of a torsion spring is pressed on the lower support, the other end of the torsion spring is pressed on the outward side of the cover plate, and the cover plate, a connecting rod, a lower crank and the cabin door structure are connected to form a four-rod mechanism. The mechanism is directly matched with an opening power source of the cabin door, the locking mode is direct and accurate, the occupied space is small, and automatic locking of the cabin door can be achieved. When the cabin door is closed, the cabin door locking position can be unlocked through an unlocking handle, the unlocking handle can serve as a door closing handle at the same time, and door closing operation is simple, coherent and prone to achieve.

    本发明涉及一种堵塞式舱门打开位置锁机构,一种堵塞式舱门打开位置锁机构,在舱门结构上固定连接有上支座和下支座,上支座铰接有上曲柄,上曲柄另一端铰接有气弹簧,气弹簧另一端与下支座铰接,盖板与下支座铰接连接,扭簧一端压紧在下支座上,另一端压紧在盖板朝外一侧,盖板、连杆、下曲柄和舱门结构连接组成四杆机构。该机构直接与舱门的打开动力源配合,锁定方式直接精准,占用空间小,可以实现舱门的自动上锁。关闭舱门时,可以通过解锁手柄解开舱门锁定位置,解锁手柄可同时充当关门手柄使用,关门操作简单连贯易实现。
