It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1:
referring to fig. 1-2, the utility model provides a dual-rigidity elastic support, which comprises an upper connecting plate 2, a lower connecting plate 4, a dual-rigidity elastic body 1 and a pressing piece 3, wherein the cross section of the dual-rigidity elastic body (1) is round, square or rectangular, the dual-rigidity elastic body 1 is arranged between the upper connecting plate 2 and the lower connecting plate 4, the pressing piece 3 is arranged on the lower surface of the upper connecting plate 2, the pressing piece 3 is embedded into the dual-rigidity elastic body 1, and the dual-rigidity elastic support acts on the upper static load;
the dual stiffness elastomer 1 includes a first steel plate 101, a first elastic layer 102, a second steel plate 103, a second elastic layer 104, and a third steel plate 105 arranged from top to bottom.
Further, the first steel plate 101 is fixedly installed on the upper connecting plate 2, and the third steel plate 105 is fixedly installed on the lower connecting plate 4. The outer diameters of the first steel plate 101 and the first elastic layer 102 are equal, the inner diameters of the first steel plate 101 and the first elastic layer 102 form a first chamber 1a, the pressing piece 3 is positioned in the first chamber 1a, and the pressing piece 3 is not contacted with the inner wall of the first chamber 1a, so that the dual-rigidity elastic body 1 is in a loose state, and a certain gap is formed between the end face of the pressing piece 3 and the second steel plate 103. The outer diameters of the second steel plate 103, the second elastic layer 104 and the third steel plate 105 are equal, the inner diameters of the second steel plate 103, the second elastic layer 104 and the third steel plate 105 form a second chamber 1b, the diameter of the second chamber 1b is smaller than that of the first chamber 1a, further, the first chamber (1 a) and the second chamber (1 b) form a functional chamber, and a plurality of functional chambers can be arranged in parallel in the dual-rigidity elastic support. The first steel plate 101, the first elastic layer 102, the second steel plate 103, the second elastic layer 104 and the third steel plate 105 are connected through bonding, and a protective layer 106 is wrapped outside. The first elastic layer 102 has a vertical stiffness that is less than the vertical stiffness of the second elastic layer 104.
The working principle of the utility model is as follows: since the first elastic layer 102 has a smaller vertical stiffness than the second elastic layer 104, the dual-stiffness elastomer 1 is loaded by the upper structure, the first elastic layer 102 is deformed first to bear the load, and the second elastic layer 104 is deformed slightly, which can be considered as providing the first stiffness by the first elastic layer 102; when the load of the upper structure increases, the first elastic layer 102 continues to be compressed, and when the compression displacement is greater than the gap between the bottom surface of the pressing member 3 and the second steel plate 103, the pressing member 3 contacts the second steel plate 103. The casting die 3 directly transmits the upper load to the second steel plate 103, the second steel plate 103 transmits the upper load to the second elastic layer 104, the second elastic layer 104 deforms to provide second rigidity, and the vertical shock insulation effect is obviously improved through the two-rigidity two-stage vertical buffering effect, so that larger displacement is prevented.
Although the utility model has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the scope and spirit of the principles of this disclosure. More specifically, various variations and modifications may be made to the component parts or arrangements of the subject combination arrangement within the scope of the present disclosure, the drawings and the claims.
