Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

A flat-open window against flowing backwards, refer to fig. 1 and fig. 2, including window frame 1 and casement, the casement includes the glass plate 2 taking the form of cuboid, the glass plate 2 stands vertically, is fixed with upper frame 3 and lower frame 4 separately on its upper and lower part, is fixed with the side frame 5 separately on its both sides at the same time; the upper frame 3, the lower frame 4 and the two side frames 5 form a mouth-shaped glass frame, and are respectively provided with a clamping groove 6 matched with the side part of the glass plate 2, namely, the glass plate 2 is fixed on the glass frame in a mode of being inserted into the clamping groove 6. One side frame 5 of the window sash is hinged to the window frame 1 through a hinge to realize installation and fixation.

Referring to fig. 1 and 2, when in use, rainwater can enter the clamping groove 6 along the gap between the glass plate 2 and the clamping groove 6 on the lower frame 4 to be accumulated and then permeate into a room along the glass plate 2, so that a plurality of drainage channels 7 are formed in the lower frame 4, and the drainage channels 7 are distributed along the length of the lower frame 4; one end of the drainage channel 7 penetrates through the bottom surface of the clamping groove 6, and the other end of the drainage channel firstly goes downwards and then penetrates through one side, facing the outdoor, of the lower frame 4.

At this time, rainwater entering the clamping groove 6 enters the drainage channel 7 and is drained from the drainage channel 7, so that the probability of rainwater permeating into the room is reduced.

Because rainwater flows into the drainage channel 7 along the outer surface of the lower frame 4 in the weather of wind and rain and flows reversely under the action of wind, so that the rainwater permeates into a room, a drainage pipe 71 which is fixedly matched is inserted into the lower port of the drainage channel 7, and the end part of the drainage pipe 71 extends out of the lower frame 4. The drain pipe 71 is provided so that rainwater, if entering the drain passage 7, will be blocked by the drain pipe 71 when moving along the outer wall surface of the lower frame 4, thereby reducing the possibility of rainwater penetrating into the room in a reverse flow manner.

Further, the drain pipe 71 is arranged such that an end thereof away from the lower frame 4 is inclined downward to increase the difficulty of the rainwater flowing back under the action of wind.

Referring to fig. 2 and 4, in order to prevent the drainage pipe 71 protruding out of the lower frame 4 from stabbing the user, an elastic protection sleeve 72 is sleeved outside one end of the drainage pipe 71 extending out of the lower frame 4, and the end of the drainage pipe 71 far away from the lower frame 4 is located in the elastic protection sleeve 72. The elastic sheath 72 may be made of rubber.

Referring to fig. 3 and 4, since the backflow preventing cavity 41 is formed in the lower frame 4, the backflow preventing cavity 41 extends along the length direction of the lower frame 4, and the drainage channel 7 penetrates through the upper wall of the backflow preventing cavity 41 and penetrates out of the lower portion of the backflow preventing cavity 41, since the backflow is relatively easy to occur if rainwater is present in the drainage channel 7 after wind is injected from the lower end of the drainage channel 7.

At this moment, water in the clamping groove 6 is discharged into the backflow prevention cavity 41 through the drainage channel 7, rainwater backflow is required to occur, and the wind blows up rainwater in the backflow prevention cavity 41 to make the backflow prevention cavity 41 backflow prevention cavity return to the clamping groove 6 from the upper portion, so that the rainwater backflow difficulty is increased, the use effect of the utility model is better.

Referring to fig. 3, in order to further increase the difficulty of backflow of rainwater, a partition plate 42 is disposed in the backflow prevention cavity 41, and the partition plate 42 partitions the backflow prevention cavity 41 to form an upper cavity 411 and a lower cavity 412 which are distributed up and down. The partition plate 42 comprises a horizontal plate 421 and an inclined plate 422, one side of the horizontal plate 421 is fixed on one side wall of the anti-backflow cavity 41, the other side is fixed with the inclined plate 422, and one side of the inclined plate 422, which is far away from the horizontal plate 421, is inclined upwards and fixed on the other side wall of the anti-backflow cavity 41; the horizontal plate 421 has a through hole 4211 along the thickness direction.

When rainwater in the clamping groove 6 enters the backflow prevention cavity 41 through the drainage channel 7 (shown in fig. 2), the rainwater firstly enters the upper cavity 411 and then enters the lower cavity 412; if wind pours into from drainage channel 7's lower extreme this moment, then its buffering is slowed down in cavity 412 earlier, then need push open the water on through-hole 4211 upper portion and just can get into epicoele 411 to the rainwater that wind leads to pours the degree of difficulty relatively bigger, the utility model discloses a rainwater is poured the ability more strongly backward.

The partition plate 42 is configured as described above, and the through hole 4211 is opened in the horizontal plate 421, so as to reduce the amount of rainwater required for blocking the through hole 4211 to prevent backflow.

Referring to fig. 3, in order to reduce the probability of damage when the glass plate 2 is mounted in the clamping groove 6 and improve the sealing performance, a rubber pad 61 is fixedly bonded to the bottom of the clamping groove 6, and the glass plate 2 abuts against the rubber pad 61; the rubber pad 61 extends along the length of the slot 6.

A plurality of through grooves 611 are formed in the contact surface of the rubber gasket 61 with the glass plate 2, and the through grooves 611 extend in the longitudinal direction of the rubber gasket 61 and have an upper opening structure. The provision of the through grooves 611 makes it more difficult for rainwater to spread along the lower bottom surface of the glass plate 2, so that rainwater is less likely to infiltrate into the room.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
