Embodiment
[0065] The hydraulic shock absorber of this embodiment comprises an upper plate groove 1, a lower plate groove 2, a position extension pin 4, a threaded shaft 5, a steel pad body 6, a rubber layer 9 and a steel plate 10. See details Figure 1(a) to Figure 6 .
[0066] The upper plate groove 1 is a concave groove body welded by steel plates, with pre-embedded steel bars welded on it, and the pre-embedded steel bars are made of precision rolled rebar, see Figure 8(a) ~ Figure 8(c) There are 4 oil pressure chambers 11, 3 spiral seat plates 7 and 3 seat plate grooves 8 distributed around each side of the upper plate groove 1, one end of the oil pressure chamber 11 is consolidated with the upper plate groove 1, and the other end can be connected with the retaining plate groove 1. plate 12 in contact. The top of the upper plate groove 1 is connected with 4 finish-rolled rebars. The oil pressure chamber 11 is arranged alternately with the seat plate groove 8 .
