TRENCH COVER

摘要

The present invention provides a trench cover which can be conveniently and easily installed, and capable of minimizing flow and noise generation caused by friction or impact. According to the present invention, the trench cover comprises: a body in the form of one between a triangle and a right-angled triangle whose one side is a hypotenuse as viewed in a plane, and including multiple drain holes in an upper surface; multiple engagement holes formed in a lateral surface on a hypotenuse when viewed in a plane among lateral surfaces of the body; an engagement ring formed in a lateral surface on a hypotenuse when viewed in a plane among lateral surfaces of the body, and formed to be inserted and engaged in the engagement hole formed in a lateral surface on a hypotenuse when viewed in a plane among lateral surfaces of the other trench cover body point-symmetrically arranged; at least one inclined surface in a lateral surface between the engagement ring and the engagement hole of the body, and formed at an incline to come close from the upper part to the lower part with the other trench cover body point-symmetrically arranged; and at least one locking lever formed to allow a width to be narrower from the upper part to the lower part in order that a gap between the body and the other trench cover body is spread apart while being lowered along the gap between the inclined surface and the inclined surface of the other trench cover body point-symmetrically arranged.
