Novel block brake

The utility model relates to a novel block brake, including the block brake body, establish compound reset spring on the block brake body, compound reset spring installs and adjusts structurally at the tension of block brake body, compound reset spring includes two piece at least disc spring, elastic rubber endotheca and elastic rubber overcoat, wherein disc spring is the spherical crown column structure, its central line goes out to establish in addition connecting shaft hole, connecting shaft hole and the coaxial distribution of disc spring, the elastic rubber endotheca is installed in disc spring's connecting shaft hole, and elastic cushion block is established to elastic rubber endotheca surface, the cladding of elastic rubber overcoat is in the disc spring outside, and elastic cushion block is established in addition to elastic rubber overcoat internal surface. This novel one side is effectual overcomes the spring structure damage that traditional stopper easily takes place and the brake fade or the not enough drawback of brake force that lead to the fact, on the other hand in addition very big reduction the noise that produces during the stopper operation, reduce the noise pollution to surrounding enviroment.
