Description

Door and window wind-proof side drain hole cover

Technical Field

The utility model relates to a door and window's drainage handhole door, especially a prevent wind side drainage handhole door.

Background

In the peripheral doors and windows of buildings, because of the condition that water is accumulated in a cavity body in a door and window structure, drainage holes are required to be opened to drain the water accumulated in the cavity body, and in order to play a decorative role and a certain windproof effect (below 400 Pa), a common drainage hole cover is installed at the drainage holes, but under the action of strong wind (above 400 Pa), the windproof effect of the common drainage hole cover is ineffective, backflow still occurs, the wind pressure is larger, the backflow is more serious, the backflow of the drainage holes in coastal areas with large wind pressure is one of main reasons for water leakage of doors and windows, and therefore, the windproof drainage hole cover is generally adopted in a high dynamic wind load area.

As shown in fig. 1, the wind-proof drain hole cover 100 ' provided on the existing door and window profile 200 ' in the market is basically that the drain hole cover base 1 ' is provided with a movable cavity 12 ' for the wind-proof sheet 2 ' to move forward and backward, and the drain port 13 ' is provided at the bottom of the drain hole cover base 1 ', that is, a longitudinal drainage structure is adopted, because the distance between the bottom of the drain hole cover 100 ' and the windowsill 300 ' is short, the drain port is blocked by a rubber strip or construction waste when workers construct the door and window profile, so that drainage is blocked, and the drainage effect is poor.

Detailed Description

The embodiment of the utility model provides a through providing a door and window wind-proof side drainage handhole door, do necessary improvement to the drainage structures of drainage handhole door for the drainage effect of drainage handhole door is better with prevent wind the effect, prevents to flow backward.

The embodiment of the utility model provides an in technical scheme for solving above-mentioned problem, the general thinking is as follows: the windproof cover is pivoted to the clamping parts at two ends of the through hole through the rotating shaft and covers the lateral drainage port from the outside to ensure that the drainage is lateral drainage, so that water can rapidly flow away without barriers, rainwater is prevented from flowing backwards, and the drainage effect of the lateral drainage hole cover is good; the side drainage hole cover is formed by assembling the hole cover base and the windproof cover, so that the die opening and the assembly are convenient; can restrict the angle that opens and shuts of preventing wind the lid through setting up spacing step and stopper, and when the wind pressure is big, prevent wind the lid and hug closely spacing step and make inseparable better between them, prevent wind the effect more, still can prevent that the rainwater from flowing backward.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present invention.

Referring to fig. 2 to 6, the side drain hole cover 100 of the present invention is disposed on a drain hole of a door/window section bar 200, the side drain hole cover 100 includes a cover base 1 and a wind-proof cover 2, a strip-shaped through hole 11 is disposed on the upper portion of the cover base 1, two sides of the through hole 11 are clamping portions 12 recessed inward, a lateral drain hole 13 is disposed below the through hole 11, a limit step 14 is disposed on an edge of the lateral drain hole 13, the limit step 14 is used for limiting the wind-proof cover 2 from being blown inward when wind pressure is large, and the wind-proof cover 2 and the limit step 14 can be tightly attached to each other when wind pressure is large, so that the wind-proof effect is better, and rainwater can be prevented from flowing backward; the left end and the right end of the inner side surface of the hole cover base 1 are respectively provided with a buckle 15 and are clamped on the door and window profile 200, the upper end and the lower end of the inner side surface of the hole cover base 1 are respectively provided with an auxiliary clamping block 16, the outer side of the auxiliary clamping block 16 is arranged in an inclined plane and is used for assisting the hole cover base 1 to be clamped on the door and window profile 200, so that the installation is firmer; the hole cover base 1 is an integral injection molding base. The top of preventing wind lid 2 is provided with a rotation axis 21, prevent wind lid 2 through rotation axis 21 pin joint in the card of through-hole 11 both ends is established portion 12 to cover from the outside in side direction outlet 13 department, prevent wind 2 outside tops of lid and be equipped with two stopper 22, can restrict the angle that prevents wind lid 2 and outwards open and shut through setting up stopper 22.

The installation method and the working principle are as follows: the bottom end of the windproof cover 2 firstly passes through a through hole 11 on the inner side surface of the hole cover base 1, then the rotating shafts 21 on two sides of the top end of the windproof cover 2 are rotatably clamped in clamping parts 12 at two ends of the through hole 11, and the windproof cover 2 naturally and vertically covers the lateral water outlet 13. When water is accumulated in the cavity of the door and window profile 200 and the wind force is smaller than the force of water flowing through the lateral water outlet 13, the water pressure pushes the windproof cover 2 open to drain, and due to the lateral water drainage, the water outlet 13 cannot be blocked by a rubber strip during the construction of workers, the drop between the water outlet 13 and the windowsill 300 is high, the flowing water can be drained timely, and the accumulation on the windowsill 300 is prevented. And when outdoor wind pressure is greatly greater than the pressure of flowing water of the lateral water outlet, the windproof cover 2 can be closed on the contrary, the windproof cover 2 is tightly attached to the limiting step 14 under the action of wind pressure to block the lateral water outlet 13, wind cannot enter the cavity of the door and window profile 200, and outdoor rainwater is prevented from flowing backwards indoors under the action of wind pressure.

The utility model relates to a simple structure, convenient to install prevent wind side drainage handhole door opens and shuts the side direction outlet 13 through setting up prevent wind lid 2 outwards and makes the drainage be the side direction drainage, compares with traditional vertical drainage structure, can let water accessible fast flow away, prevents that the rainwater from pouring backward, makes the drainage of side drainage handhole door 100 effectual; the side drainage hole cover 100 is formed by assembling the hole cover base 1 and the windproof cover 2, so that the mold opening and the assembly are convenient; can restrict the angle that opens and shuts of preventing wind lid 2 through setting up spacing step 14 and stopper 22, and when the wind pressure is big, prevent wind lid 2 hug closely spacing step 14 and make inseparable better between them, prevent wind the effect more, still can prevent that the rainwater from flowing backward.

Although specific embodiments of the present invention have been described, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the claims appended hereto.
