Abstract

The invention discloses an armor preventing a human body from turning around in the telegraph pole toppling process. The armor comprises a frame armor body formed by a front armor body, a right armor body and a rear armor body, wherein the front armor body, the right armor body and the rear armor body are arranged on three sides of the frame armor body. A pole buckling ring is fixed in the front of the front armor body and forms a closed circle through a ring buckle. A tilted ground contact long pipe is fixed on the left of the back of the rear armor body through a shaft key. A supporting and pulling aluminum sheet and two pulling aluminum sheets jointly act on the tilted ground contact long pipe so as to enable a straight pipe portion of the tilted ground contact long pipe to be perpendicular to the rear armor body surface. According to the armor, in the process that a telegraph pole topples to the ground, the human body is turned around from the position below the pole to the position above the pole, so the disaster that the toppled telegraph pole knocks down a person is avoided; reinforce ribs are arranged between the armor bodies, so the armor prevents the human body from being squeezed when the human body turns around in the telegraph pole toppling process; soft cushions are arranged on the inner sides of the armor bodies to play a buffering role, so the damage to the human body can be reduced when the armor plays a role in preventing the human body from turning around in the telegraph pole toppling process.
