Description

Technical Field

[0001] The utility model relates to the technical field of door and window drainage, and in particular to a windproof drainage structure for a window sash. Background Art

[0002] Doors and windows in buildings mainly play the role of lighting and ventilation. For doors and windows installed on the exterior walls, water will accumulate in the window frames on rainy days. In extreme weather with strong winds, due to the high outdoor pressure, the accumulated water in the windows cannot be discharged to the outside in time, and may even easily flow back into the room or soak and corrode the door and window hardware, seriously affecting the normal use of the doors and windows. Therefore, doors and windows need to be designed with windproof drainage structures for drainage.

[0003] Most of the existing door and window drainage structures adopt the method of processing drainage holes on the outdoor side of the lower frame or the horizontal center mullion for drainage, and then installing a windproof drainage hole cover on the outdoor side. This drainage method may cause water to overflow into the room due to untimely drainage when there is heavy rain or a lot of water accumulation, and the windproof drainage hole cover is easily knocked off during the transportation of doors and windows, resulting in functional loss. Another part is to design a hidden drainage trough for lower drainage on the lower frame or the horizontal center mullion. This drainage method is conducive to drainage, but this hidden drainage trough lacks a windproof structure and is greatly affected by wind. Utility Model Content

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-Figure 5 As shown in the figure, the present invention is a windproof and drainage structure for a window sash, including a vertical plate 1 of the window sash and a drainage cover 3. The vertical plate 1 of the window sash is used for fixed installation on the window wall. A horizontally arranged drainage bottom plate 2 is fixedly connected to the vertical plate 1 of the window sash. A drainage opening 11 for drainage is arranged on the vertical plate 1 of the window sash, and the lower end of the drainage opening 11 is flush with the upper surface of the drainage bottom plate 2. The drainage cover 3 is detachably installed at the drainage opening 11. A drainage groove 36 for drainage is arranged on the drainage cover 3, and a shielding structure for preventing rainwater and wind from flowing back is arranged at the drainage groove 36.

[0025] The drainage cover 3 includes a cover base 31 and a clamping convex block 32 fixedly arranged on the cover base 31. The clamping convex block 32 penetrates through the drainage opening 11 and extends to the other side of the vertical plate 1 of the window sash. The drainage groove 36 is arranged on the clamping convex block 32 and the cover base 31.

[0026] Specifically, the length and width of the cover base 31 are both larger than those of the clamping convex block 32, and the length and width of the cover base 31 are both larger than those of the drainage opening 11, which can block the drainage opening 11 to ensure the stable installation of the drainage cover 3, realize the outer limit of the installation of the drainage cover 3, and at the same time close the drainage opening 11 so that rainwater is discharged from the drainage cover 3, and prevent the wind and rain outside from entering the room through the drainage opening 11, effectively ensuring the windproof and rainproof effect of the window sash.

[0027] Furthermore, the connecting convex block 32 has a U-shaped structure. The side with the opening is used for opening the drainage groove 36, and the other three sides are all convex to ensure the stability of the connection and the blocking of the drainage opening 11.

[0028] Connecting card plates 33 for snap-fitting and installing the drainage cover 3 are fixedly arranged on both sides of the clamping convex block 32.

[0029] The setting of the connecting clamp plate 33 facilitates the installation of the drain buckle cover 3, and the connecting clamp plate 33 is an elastic structure, which facilitates the rapid disassembly and assembly of the drain buckle cover 3.

[0030] Balancing grooves 34 are disposed on both sides of the buckle cover base 31 . The balancing grooves 34 are located below the connecting clamp plate 33 and are connected to the drain port 11 .

[0031] The arrangement of the balance tank 34 allows air pressure to circulate between the outdoor and indoor areas, thereby ensuring air pressure balance and preventing rainwater from being unable to be discharged normally due to the outdoor air pressure being greater than the indoor air pressure.

[0032] The buckle cover base 31 is located in the drainage groove 36 and is provided with a plurality of connection supports 35 , and the connection supports 35 are butted against the outer ends of the window sash vertical plate 1 .

[0033] The provision of the connecting support 35 improves the overall strength of the drain buckle cover 3, thereby ensuring the installation stability and service life of the drain buckle cover 3.

[0034] The shielding structure includes a plurality of connecting upright plates 37 fixedly disposed in the drainage groove 36 on the snap-fitting protrusion 32 , and a lower baffle plate 38 and an upper baffle plate 39 inclined toward the buckle cover base 31 are disposed on both sides of the connecting upright plates 37 .

[0035] The inclined widths of the lower baffle plate 38 and the upper baffle plate 39 are both greater than half of the distance between adjacent connecting vertical plates 37 .

[0036] By providing a unidirectionally inclined lower baffle 38 and upper baffle 39, rainwater can be discharged normally and quickly through the lower baffle 38 and the upper baffle 39 during indoor drainage. When outdoor wind and rain need to enter the room through the drainage groove 36, two sets of baffles with overlapping vertical widths are used to double block the wind and rain, which can effectively prevent outdoor wind and rain from flowing back into the room through the drainage groove 36, thereby improving the wind and rain protection effect of the window sash.

[0037] The working principle of the utility model is as follows: the connecting clamping plates 33 on both sides are pressed to insert the clamping protrusion 32 into the drain outlet 11. When the clamping protrusion 32 is fully inserted, the connecting clamping plates 33 on both sides rebound and reset, and the drainage buckle cover 3 is stably installed on the window sash vertical plate 1. When rainwater falls on the drainage bottom plate 2, it then enters the drainage groove 36. By setting a unidirectional inclined lower baffle plate 38 and an upper baffle plate 39, rainwater can be discharged normally and quickly through the lower baffle plate 38 and the upper baffle plate 39 during indoor drainage. When outdoor wind and rain need to enter the room through the drainage groove 36, the wind and rain are doubly blocked by two sets of baffles with overlapping vertical widths, which can effectively prevent outdoor wind and rain from flowing back into the room through the drainage groove 36, thereby improving the wind and rain protection effect of the window sash.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
