When the extreme atress condition appears, guide rail installed part 3, spacing support 4 upwards compresses second vibration isolation material 8 with spacing strake 5's blend stop at e, the side 3B of guide rail installed part 3 contacts with spacing strake 5's the portion of bending 5H, perhaps the side 3C of guide rail installed part 3 contacts with spacing strake 5's the portion of bending 5I, first vibration isolation material 7 is not out of shape this moment again, spacing strake 5's the portion of bending 5H, the portion of bending 5I upwards with guide rail installed part 3's side 3B at e, side 3C's clearance is spacing size promptly. When the distance between the guide rail 2 and the wall of the building is large, the bending part 5H and the bending part 5I of the limiting support plate 5 can realize the limiting function and the function of a reinforcing structure.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
