Embodiment Construction
[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] like Figure 1 to Figure 18 As shown, a tension locking device used on a vibration-isolating rubber bearing includes: mounting steel plates 1a, 1b, external sleeves 2a, 2b, large nuts 3a, 3b, threaded screws 4a, 4b, splicing nuts 5a , 5b, tie rod 6.
[0037] like figure 1 , Image 6 The common lead-core rubber support 7 is composed of a connecting plate 8 , a sealing plate 9 , a steel plate 10 , a rubber layer 11 , and a lead core 12 .
[0038] like Figures 14 to 16 As shown, the external sleeve 2 contains threads that can be matched with the threaded screw 4 . like Image 6 , Figure 7 As shown, the lengths of the outer sleeves 2a, 2b are greater than or equal to twice the overhanging lengths of the threaded screws 4a, 4b.
[0039] like figure 1 , figure 2 and Figure 7 As shown, the threaded screws 4a, 4b respectively pass...
