The support 2 is placed between the lower seat plate 4 and the upper seat plate 1 and is disconnected from the upper seat plate 1 and the lower seat plate 4, i.e. there is no connection between the support 2 and both the upper seat plate 1 and the lower seat plate 4. So that the support 2 can be swung with respect to the seat plate. The energy dissipater 3 on the periphery of the support member 2 is arranged between the upper support plate 1 and the lower support plate 4; and the two ends of the energy dissipater 3 are correspondingly connected with the upper support plate 1 and the lower support plate 4.

The energy dissipators 3 are symmetrically distributed about the support 2, and a plurality of the energy dissipators 3 are uniformly distributed in the circumferential direction on the periphery of the support 2. The energy dissipater 3 moves together with the upper and lower support plates when the support member 2 swings, and then generates bending and tension-compression deformation, thereby playing an energy dissipation role. The energy dissipaters 3 are symmetrically arranged on the periphery of the support piece 2, so that the support piece 2 is stressed stably, and the energy dissipation capability, the self-resetting capability and the stability of the support are improved.

On the basis of the above embodiment, further, referring to fig. 3, the cross-sectional dimension of the energy consumer 3 at both ends is larger than the cross-sectional dimension of the middle portion. The end parts of the two ends of the energy dissipater 3 are mainly used for being connected with the upper support plate and the lower support plate. The middle part of the energy consumer 3 is a main energy consumption section 3-1. The cross section of the two ends of the energy dissipater 3 is large in size, so that the energy dissipater can be conveniently connected with the upper support plate and the lower support plate, and meanwhile, the failure of the energy dissipater at the connection part is avoided.

Then, the energy dissipater 3 is screwed out of the internal threaded hole 7 of the upper support plate 1, and the lower end of the energy dissipater 3 is screwed into the lower support plate 4 at the same time until the energy dissipater 3 reaches the final required position, which can be the position where the two ends of the energy dissipater 3 are inserted into the upper and lower support plates at the same depth.

Therefore, the energy dissipater 3 can be installed without simultaneously moving the upper support plate and the lower support plate when the energy dissipater 3 is screwed, and the energy dissipater is ingenious in design, simple and convenient to operate and easy to realize. The disassembly of the energy dissipater 3 is performed in reverse operation according to the above steps.

The distance between the lower end of a shear key 5 connected with the upper support plate 1 and the side wall of the support member 2 is larger than the distance between the upper end of the shear key and the side wall of the support member 2; the distance between the upper end of the shear key 5 connected with the lower support plate 4 and the side wall of the support 2 is larger than the distance between the lower end of the shear key and the side wall of the support 2. The shear keys 5 have a limiting effect on the supporting piece 2 around the top end and the bottom end of the supporting piece 2, and can prevent the supporting piece 2, the lower support plate 4 and the upper support plate 1 from sliding relatively. The shear bond 5 may be welded to the upper and

lower seat plates

1, 4.

The distance between one end of the shear key 5 far away from the support plate and the support 2 is larger. Referring to fig. 2, so that the shear key 5 acts as a limit to the support member 2 to prevent the support member 2 from sliding horizontally and twisting, the support member 2 may swing between the shear keys 5. This arrangement avoids the shear key 5 colliding with the support member 2 during rocking. The arranged shear keys 5 are used for carrying out horizontal displacement limitation on the upper surface and the lower surface of the support piece 2, so that the support piece 2 is prevented from sliding and twisting, and the limitation on normal swinging of the support piece 2 can be ensured.

Further, the shear key 5 is fixedly arranged at the upper and lower end corners or the periphery of the support member 2. Specifically, referring to fig. 5, a shear key 5 is disposed at a corner of each side of the supporting member 2, so as to limit the supporting member 2 at each side, and the supporting member 2 cannot slide in any direction.

The shear key 5 is a columnar structure with a triangular section. The fixed upper and lower end corner or all around of arranging in support piece 2 prevents support piece 2 and lower support plate 4 and upper bracket board 1 to take place relative slip, can guarantee that support piece 2's normal rocking is unrestricted simultaneously. The shear key 5 arranged at the same time can limit the support 2 from twisting.

Specifically, the cross-sectional shape of the shear key 5 may be a right triangle, wherein one of the legs is adapted to be connected to the upper seat plate 1 or the lower seat plate 4, and the hypotenuse faces the support member 2.
