Rubber spring for bearing vertical large deformation load in long and narrow space

A rubber spring for bearing a vertical large deformation load in a long and narrow space comprises an annular mandrel, an annular outer sleeve and a rubber body vulcanized between the annular mandrel and the annular outer sleeve, the inner side wall of the annular outer sleeve and the outer side wall of the annular mandrel are inclined planes, and the rubber body is vulcanized between the inner side wall of the annular outer sleeve and the outer side wall of the annular mandrel. According to the rubber spring, the mandrel, the outer sleeve and the rubber body are all designed to be annular, so that the whole rubber spring can adapt to a long and narrow installation space. According to the rubber spring, the limited long and narrow space is fully utilized, and compared with the prior art, other accessory structures are not designed, so that the rubber body has a more sufficient vulcanization area in the limited space, the size of the rubber body can be maximized as much as possible, the rubber spring can have
