The invention provides an impact-resisting protective airtight door which comprises a door plate, elastic pieces, first springs, second springs, first collapse bodies and second collapse bodies. Whenthe impact-resisting protective airtight door is impacted by large impact waves, the elastic pieces are firstly impacted by the impact waves to compress the first springs, the second springs, the first collapse bodies and the second collapse bodies, and energy of the impact waves is converted into deformation so as to be absorbed to prevent deformation of the door plate. In addition, if the firstcollapse bodies and the second collapse bodies are broken after absorbing a large amount of energy, the first springs and the second springs eject the elastic pieces, the first collapse bodies and thesecond collapse bodies together to prevent the door plate from being stuck by the first collapse bodies, the second collapse bodies and the elastic pieces, and a part of impact waves is prevented from directly impacting the door plate. Therefore, the impact-resisting protective airtight door cannot deform when bearing large impact waves, and the airtight effect is good.
Description
technical field [0001] The application belongs to the field of protective equipment, and in particular relates to an impact-resistant protective airtight door. Background technique [0002] Large-scale civil air defense projects are generally composed of many protective units. In order to ensure that the loss of the protective function of one protective unit does not affect the performance of other protective units during wartime, it is necessary to set protective airtight doors that can carry two-way loads separately at the communication ports of the protective units. [0003] The existing protective airtight door includes a door leaf and a door frame connected by hinges and a locking structure connecting the door leaf and the door frame. The sealing beam is driven by at least two pairs of crank rocker lifting mechanisms to seal the lower edge of the door leaf and the ground. Door leaf, operated by handles at both ends. However, the existing protective airtight doors are ...
