Self-tightening wind power thermal shrinkage connecting rubber pipe

The utility model relates to the technical field of heat-shrinkable tubes, and discloses a self-tightening wind power heat-shrinkable connecting rubber tube which comprises a flame-retardant protective layer, an outer rubber layer is fixedly connected to the inner side of the flame-retardant protective layer, a buffer block is fixedly connected to the inner side of the outer rubber layer, and a shrinkage gap is formed in the inner side of the outer rubber layer. According to the self-tightening wind power thermal shrinkage connecting rubber pipe, the flame-retardant protection layer made of a cross-linked polyolefin material can provide flame-retardant protection for the outer rubber layer and prevent combustion, and the buffer block made of a silica gel material has good high-temperature resistance and good flexibility; a plurality of buffer blocks and contraction gaps between the outer rubber layer and the inner rubber layer can play a role in buffering and protecting wire harnesses and the like wrapped ins
