The invention discloses an elevator middle labyrinth-free type fireproof door which comprises a left door plate and a right door plate, fireproof labyrinth structures are arranged on the side portions and the tops of the left door plate and the right door plate, the left door plate and the right door plate are included, and the connection position of the left door plate and the right door plate is of a plane attaching structure. By means of the optimized structure, production line equipment investment can be effectively reduced, production procedures are optimized, production efficiency is improved, elevator installation efficiency is effectively improved in the installation process, and the failure rate of the fireproof door is effectively reduced in the elevator using process. After the maze-free fire-resistant door is adopted, the middle position of the door plate is of a maze-free structure, so that the stress area is increased compared with a traditional maze fire-resistant door, and the risk of being clamped is reduced.

    本发明公开了一种电梯中部无迷宫型防火门,包括左门板以及右门板,左门板以及右门板的侧部以及顶部设置防火迷宫结构,包括左门板以及右门板,左门板以及右门板接洽位置呈平面贴合结构,相对于传统有迷宫耐火门,通过上述优化结构,可以有效减少产线设备投入、优化了生产工序,提高了生产效率,在安装过程中,有效提高电梯安装效率,在电梯的使用过程中,有效的减少耐火门故障率。无迷宫耐火门后,门板中间位置为无迷宫结构,相对于传统有迷宫耐火门增加了受力面积,减少了被夹伤的风险。
