When the inner box 1 and the outer box 2 move relatively, the actuating rod clamping ring 801 drives the lower limiting plate 5, the middle limiting plate 6 and the upper limiting plate 7 on one side to move together, so as to compress the lower helical compression spring 3 and the upper helical compression spring 4 on one side, thereby storing self-resetting energy of the damper.
Once an earthquake occurs, the inner box body 1 and the outer box body 2 generate relative motion, the high-strength bolt I11 is connected with the steel belt 201 with slits around the outer box body 2 to move together with the lower limiting plate 5, the middle limiting plate 6 and the upper limiting plate 7, the steel belt 201 with slits around the outer box body 2 deforms to dissipate energy, at the moment, the lower helical compression spring 3 or the upper helical compression spring 4 in the hollow part of the inner box body 1 or the outer box body 2 is continuously compressed along with the motion of the middle limiting plate 6 or the upper limiting plate 7, the lower helical compression spring 3 or the upper helical compression spring 4 is compressed to generate a restoring force opposite to the relative motion direction of the inner box body 1 and the outer box body 2, the restoring force plays a certain energy consumption role, and the restoring force plays a role in self-resetting the inner box body 1 and the outer box body 2; once the earthquake action is reduced or stopped, the accumulated energy of the lower helical compression spring 3 and the upper helical compression spring 4 can gradually reset the steel belt 201 with slits around the outer box body 2, so that the self-resetting function of the damper is realized, and the residual deformation of the building structure is reduced or even eliminated.
