The invention discloses a framework material type tire flap which comprises a flap body and a rim, the rim is provided with a rim hole, the flap body comprises a pure rubber strip and a framework material rubber block, the framework material rubber block is arranged in the pure rubber strip, the framework material rubber block comprises a first prefabricated part and a second prefabricated part, and the first prefabricated part and the second prefabricated part are arranged in the pure rubber strip. The number of the first prefabricated parts and the number of the second prefabricated parts are both two, the two second prefabricated parts are arranged between the two first prefabricated parts, the two first prefabricated parts are symmetrically arranged on the two sides of the second prefabricated parts, and the two corresponding side walls of the two second prefabricated parts are fixedly connected with the sides, close to each other, of the two first prefabricated parts correspondingly. Through the arrangement of the pure rubber strip and the framework material rubber block, the strength of the inflating valve hole part of the flap body can be improved, and the strength of the inflating valve hole part is far higher than that of pure rubber, so that the flap body cannot be extruded out of a rim hole.
本发明公开了一种骨架材料式轮胎垫带,包括垫带本体和轮辋,所述轮辋上设有轮辋孔,所述垫带本体包括纯胶胶条和骨架材料胶块,所述骨架材料胶块设置在纯胶胶条内部,所述骨架材料胶块包括第一预制件和第二预制件,所述第一预制件和第二预制件均设有两个,两个所述第二预制件设置在两个所述第一预制件之间,两个所述第一预制件对称设置在第二预制件两侧,两个所述第二预制件相对应的两侧壁分别与两个第一预制件相互靠近的一侧固定连接,通过纯胶胶条和骨架材料胶块的设置,可提高垫带本体气门嘴孔部位强度,气门嘴孔部位处强度远高于纯橡胶强度,使垫带本体不能从轮辋孔挤出。
