But reuse's protection network friction energy absorber

The utility model discloses a but reuse's protection network friction energy absorber, including closing device, two arc spring boards, the I and the II that breaks out break out, closing device includes two upper and lower clamp plates, bolt and nut structure and spring shim, the bolt and nut structure runs through behind the two upper and lower clamp plates, with the common locking pressure plate of spring shim, the arc spring board stacks from top to bottom between closing device's two upper and lower clamp plates, and carry out the front and back by the bolt and nut structure and fix, thearc spring board is the make progress steel sheet of perk of one end, the I and the II that breaks out of breaking out is located the heteropleural port department of different clamp plates respectively. Relative slip and deformation take place through two blocks of arc spring boards for this device, will strike kinetic energy and turn into friction internal energy and deformation elastic potential energy, reach the energ
