the cover plate is fixed on the drain hole cover body to cover the drain hole. The drainage hole cover with the structure can not well prevent strong wind and dust from entering a room, and can not prevent rainwater from flowing back to the interior of a door or a window in case of heavy rain.

Chinese patent: a drain hole cover, patent No.: 2018208659650, this drain handhole door is including covering the main part and preventing wind the board, cover the main part both sides pterygoid lamina and connect the bottom plate of both sides pterygoid lamina, be equipped with the wind gap on the bottom plate, still be equipped with the entablature between the pterygoid lamina of both sides, the entablature passes through the lacing film welding in order to be connected with the bottom plate, prevent wind board top both sides and be equipped with the projection, the projection is taken on the lacing film, so that prevent wind the board and cover the wind gap, the drain handhole door is fixed on the guide rail outlet so that the wind gap communicates with each other with the guide rail outlet, prevent wind. Through the structure design, when strong wind, sand and dust and storm rain are met, the wind-proof plate is tightly pressed on the wind opening by the acting force of outdoor wind or rain, and therefore, the strong wind, rain and sand and dust can be well prevented from entering the indoor from the water drainage hole. When water is accumulated in the guide rail, the wind-proof plate can be opened under the action of water pressure, so that the wind port is opened, and the accumulated water is discharged.

However, in this drain hole cover, the protruding column on the wind-proof plate is likely to slide down from the hanging piece only by attaching the wind-proof plate to the hanging piece without restricting the wind-proof plate from the left and right. Meanwhile, the connection strength between the outer cover and the cover main body is not enough, and the separation is easy to generate.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve prior art not enough, provide one kind when satisfying waterproof dustproof demand of preventing wind, the higher drainage handhole door structure of joint strength between the part.

In order to realize the purpose, the design a drainage handhole door structure, its characterized in that includes an dustcoat, the inside cavity that is equipped with of dustcoat, dustcoat upper portion one side and rear portion one side opening, the lateral wall all is equipped with the spout about the dustcoat cavity, be equipped with the draw-in groove on the spout, the bottom of dustcoat cavity is equipped with two stoppers, a separation blade, the anterior one side of separation blade is equipped with the connecting axle, the connecting axle sets up in the clearance of stopper and the anterior lateral wall of cavity, the width of separation blade cooperatees with the distance between two stoppers, a buckle closure, the buckle closure middle part is equipped with the wash port, be equipped with the connecting piece on the buckle closure, the connecting piece is used for connecting the door and window section bar, the buckle closure both sides are.

The buckle cover is horizontally pushed into the outer cover sliding groove until the buckle on the buckle cover enters the clamping groove on the outer cover sliding groove, and the buckle cover, the side wall of the inner cavity of the outer cover and the limiting block limit the connecting shaft of the blocking piece together.

Be equipped with the connecting block on the anterior lateral wall of dustcoat inner chamber, the connecting block is used for spacing about carrying on the buckle closure.

One side of the buckle is of an inclined plane structure.

Compared with the prior art, the utility model, its advantage lies in:

1. two stoppers about being equipped with in the outer cover inner chamber, the distance between the stopper cooperatees with the width of separation blade, prevents that the separation blade from moving about and leading to breaking away from the outer cover.

2. Be provided with the buckle on the buckle closure, the buckle cooperatees with the draw-in groove on the dustcoat spout for overall connection is more firm, simultaneously because the lock is died between draw-in groove and the buckle, can guarantee that middle separation blade can not drop.

3. The separation blade is firstly pressed into the outer cover, then the buckle cover is horizontally pushed into the outer cover sliding groove until the buckle on the buckle cover enters the sliding groove of the outer cover, the whole structure is simple, and meanwhile, the installation is convenient.
