The invention relates to a fireproof sealing blanking cap for an automobile floor, and the fireproof sealing blanking cap comprises: a fireproof blanking cap, wherein one side of the fireproof blanking cap is provided with a plurality of elastic clamping parts, and the bottom ends, far away from the fireproof blanking cap, of the elastic clamping parts elastically deviate towards the direction far away from the central axis of the fireproof blanking cap, so that the bottom ends of the elastic clamping parts penetrate through floor holes and then are clamped and fixed with the automobile floor; and a hot melting sealing body which is arranged on the outer sides of the elastic clamping pieces, located on the peripheral edge of the bottom face of the fireproof blocking cover and connected with the fireproof blocking cover in a sealed mode, wherein the inner edge of the hot melting sealing body abuts against the elastic clamping pieces. The elastic clamping piece arranged on one side of the fire-resistant blanking cap can stretch into a floor hole after certain elastic deformation and achieve clamping installation after elastic reset, the plate face of the fire-resistant blanking cap is tightly attached to the automobile floor, a certain sealing effect is achieved, in the follow-up whole automobile coating and baking machining step, the bottom face of the hot melting sealing body is partially melted, and the cap is bonded and fixed with a sheet metal part of the automobile floor, so that smoke on the other side of the automobile floor cannot enter an automobile body through a floor hole.
本申请涉及一种汽车地板用防火密封堵盖,其包括:耐火堵盖,其一侧设有多个弹性卡接件,弹性卡接件远离耐火堵盖的底端向远离耐火堵盖中轴线的方向弹性偏离,以用于在弹性卡接件的底端在穿过地板孔后与汽车地板卡接固定;热熔密封体,其设于多个弹性卡接件外侧,其位于耐火堵盖底面周沿并与耐火堵盖密封连接,其内沿与弹性卡接件抵紧。耐火堵盖一侧所设置的弹性卡接件可在一定弹性形变后伸入地板孔内,并在弹性复位后实现卡接安装,使耐火堵盖的板面紧贴汽车地板,形成一定密封效果,在后续汽车整车涂装烘烤加工步骤中,热熔密封体的底面将产生部分熔化,与汽车地板钣金件进行粘接固定,保障汽车地板另一侧烟气无法通过地板孔进入至车体内。
