Embodiment Construction
[0015] The present invention as figure 1 As shown: a capsule body 1 with a concave inner bottom surface made of rubber, with a balance board 4 inside the capsule body 1 , and the balance board 4 is fixedly connected to the inner bottom surface of the capsule body 1 .
[0016] A nut 5 is embedded at the center of the inner bottom surface of the capsule body 1 , and the balance plate 4 is fixedly connected to the inner bottom surface of the capsule body 1 through the screw 2 connected with the nut 5 . In order to ensure the connection effect, a pressure plate (acting as a gasket) can be added.
[0017] The diameter of the balance plate 4 is slightly smaller than the inner diameter of the capsule body 1, so that the gap between the balance plate 4 and the inner wall of the capsule body 1 forms a damping air passage.
[0018] Another embodiment of the present invention is as figure 2 As shown: the body of the balance board 4 is made of hard material, and the edge of the balance...
