Abstract
The utility model relates to an under cover of guard rail grid, which solves the problems that the existing under cover of grid made up of plastic goes moldy easily and the lifetime is short. The cover body is a barrel shape with an open upper end and the cover body is made up of plastic. The inner edge of the lateral wall of the cover body is matched with the outer edge of the grid, and the bottom surface of the cover body is provided with through holes which can be circle, oval and regular polygon. The cross-section of the lateral wall of the cover body is an oblong with arced chamfering and one literal long edge of the cross-section bulges in arc outwards. The cross-section of the lateral wall is oval or circular. Thus, the utility model has the advantages of simple structure, easy producing, long service life and good external appearance, and rain can not be accumulated and the under cover of guard rail grid can not go moldy and blacken.
Description
Technical field
The utility model relates to a kind of exterior decoration and protection guardrail (fence, railing), particularly relates to a kind of guardrail grizzly bar bottom end cover.
Background technology
The grizzly bar of the outdoor guardrail that is made of plastics at present all is a hollow cylindrical, and the lower end periphery of hollow grill pieces all is fitted with the uncovered barrel-shaped bottom end cover in upper end usually.The inventor finds through long-term observation: usually can there be rainwater in rainy season in the bottom end cover, and the long-pending bottom end cover periphery Chang Yinzi that rainwater arranged mildew bacterium and blackening, mouldy bottom end cover is neither attractive in appearance, also can accelerated oxidation degraded, reduction of service life greatly.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of guardrail grizzly bar bottom end cover that can not accumulate rainwater is provided.
For achieving the above object, the utility model guardrail grizzly bar bottom end cover is uncovered barrel-shaped in the upper end that is made of plastics, and the sidewall inner edge of lid matches with the column outer rim, and the lid bottom surface is shaped on through hole.So design, the introducing of through hole can in time be discharged the rainwater that infiltrates in the lid, thus prevent to mildew now in the bottom end cover bacterium and blackening, accelerated oxidation degraded help increasing the service life and keep beautiful color for a long time.
As optimization, through hole can be circular, oval, regular polygon.So design, more convenient manufacturing.
As optimization, the cross section of covered body wall is the rectangle of band arc angling, and the cross section of sidewall is for the outside curved protrusion of rectangle and the long limit of a side of band arc angling, and is oval or circular.So design, more convenient installation and use.
After adopting technique scheme, the utility model guardrail grizzly bar bottom end cover has simple in structure, easily manufactured, can not accumulate the mouldy blackening of rainwater, long service life, the advantage that outward appearance is good.
