A lock of yielding unit of a multi-link metal frame yielding support includes a rod-stabilizer that includes a shaped rod with middle concave section and two end sections, and two thrusts arranged as closed in perimeter bent profiles and welded joints connected to the end sections of the shaped rod, and fixation cramp in U-like form, with threaded ends that go through thrusts, and provided with nuts, at that the rod-stabilizer, and the fixation cramp tightly go in closed perimeter round the inner and outer fixation links in yielding units, connected to each other with lap, with possibility of respective slide with support under load, with bottoms, inclined side walls and flanges, and made of box mine special profile with same standard size. In the rod-stabilizer each thrust is arranged as outer and inner thrust elements connected to each other with welded joints in such a way that together those form a box profile closed in perimeter, with vertical channel for placement of threaded end of fixation cramp, with horizontal thrust surface that is in contact with the lower surface of the flange of the inner link, and the side inclined thrust surface that is in contact with the side inclined surface of the flange of the inner link. |
