Therefore, the outer limiting plate 7 can only move forward in one direction on the second member. If the outer limiting plate 7 moves backwards on the second component, the outer limiting plate is limited by the clamping groove, and is correspondingly fixed on the second component.
As shown in fig. 9 to 10, the outer surface of the slot plate 8 is saw-toothed, and the right side of the horizontal plate 302 of the slot plate 3 is extended inward to form saw-toothed slots.

As shown in fig. 16, the shell fixing plate 115 is further formed by two symmetrical baffles, namely a shell baffle one 1151 and a shell baffle two 1152.
As shown in fig. 17 to 18, the member five is pushed forward from the rear side of the housing 111, and is incorporated into the housing 111. The upper baffle 112 is pushed in through a rectangular hole in the upper part of the side surface of the housing 111, is caught at the rear side of the housing 111, and then the middle baffle 113 is pushed in through a rectangular hole in the lower part of the side surface of the housing 111. And then moves upward to be caught in the catching groove of the upper baffle 112. The lower baffle 114 is then pushed in through the rectangular hole in the lower side of the shell 111. Finally, the nut is put into the rectangular hole of the shell fixing plate 115, and then the shell fixing plate 115 is buckled at the end of the front baffle 1 through the groove, so that the shell 11 is assembled. Finally, the clamping groove plate 8 is pushed forwards until the end of the clamping groove plate contacts the outer limiting plate 7, and the damper is assembled.
The annular energy dissipation plate damper can be reused after earthquake by replacing the upper energy dissipation piece 9, the lower energy dissipation piece 10, the foam metal I4 and the foam metal II 92. If the vibration energy is large or the allowable displacement is small, a plurality of dampers can be installed and used in parallel, so that the rigidity of the whole damper can be increased, the number of energy consumption components can be increased to dissipate more vibration input energy, and the displacement of the protected components can be reduced.
