Passage rubber

The invention discloses a passage rubber which comprises a rubber body, a threading hole is arranged at an inner middle position of the rubber body, and buffer holes are symmetrically arranged at twoends of the threading hole. The passage rubber has a novel design and is mainly applied to road engineering, wires exposed on a road are protected, the wires are protected from being crushed by passing vehicles, the set buffer holes has a buffering effect, the fracture of the rubber due to excessive pressing under the pressure of the vehicles is prevented, thus the service life of the rubber bodyis improved, and the passage rubber is made of an ethylene-propylene-diene monomer rubber material and has good wear resistance and a long service life. 本发明公开了种过路胶皮，包括胶皮本体；所述胶皮本体的内侧中间位置处设置有穿线孔，所述穿线孔的两端对称设置有缓冲孔。本发明设计新颖，主要是应用在道路工程上，对裸露在马路上的电线起保护作用，防止过往的车辆将电线压坏，设置的缓冲孔起到缓冲作用，防止胶皮在车辆的压力下过度挤压而断裂，从而增加胶皮本体的使用寿命，采用三元乙丙橡胶材料制成，耐磨性好，使用时间长。
