Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window drainage, and in particular to a window sash drainage structure. Background Art
[0002] In the doors and windows outside the building, since there will be water accumulation in the cavity inside the door and window structure, drainage holes must be opened to drain the water in the cavity. In order to achieve a decorative effect and a certain windproof effect (below 400Pa), ordinary drainage hole covers are installed at the drainage holes. However, under strong winds (above 400Pa), the windproof effect of ordinary drainage hole covers does not work, and backflow will still occur. The greater the wind pressure, the more serious the backflow. In coastal areas with high wind pressure, backflow of drainage holes is one of the main causes of door and window leakage. For this reason, windproof drainage hole covers are generally used in areas with high dynamic wind loads.
[0003] There are basically two types of windproof drain hole covers available on the market: one is an internal windproof sheet. In order to reduce the overall assembly difficulty, the drain hole cover base is basically designed to be assembled in two parts. There is a gap in the drain hole base, resulting in poor windproof effect; the other is an external windproof sheet. When this type of windproof drain hole cover exposes the structure to the outside, the outside wind blows directly on it, making it unable to flip over, thereby blocking the drain trough and preventing normal drainage. Utility Model Content
[0004] The utility model aims to provide a window sash drainage structure to solve the technical problem that when an external windproof drainage hole cover is exposed to the outside, the outside wind blows directly against it, making it unable to flip over, thereby blocking the drainage groove and causing failure of normal drainage.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A window sash drainage structure comprises a lower vertical plate and a drainage buckle cover, wherein the upper end of the lower vertical plate is fixedly connected to a drainage bottom plate, an upper vertical plate is fixedly provided on a side edge of the drainage bottom plate close to the lower vertical plate, a drainage hole is provided on the upper vertical plate, the lower end of the drainage hole is flush with the upper end surface of the drainage bottom plate, the drainage buckle cover is detachably installed at the drainage hole, a drainage groove for drainage is provided on the drainage buckle cover, and a flap for preventing outdoor wind and rain from backflowing is installed in the drainage groove.
[0007] As a further solution of the utility model: the drainage buckle cover includes a buckle cover base and a snap-on protrusion fixedly arranged on the buckle cover base, the snap-on protrusion passes through the drainage hole and extends into the other side of the upper vertical plate, and the drainage groove is arranged on the snap-on protrusion and the buckle cover base.
[0008] As a further solution of the utility model: connecting clamping plates for clamping and installing the drain buckle cover are fixedly arranged on both sides of the clamping protrusion.
[0009] As a further solution of the utility model: a plurality of support columns are arranged at the drainage groove on the clamping protrusion, one end of the support column is fixedly connected to the clamping protrusion, and the other end of the support column is against the drainage bottom plate.
[0010] As a further solution of the utility model: balance grooves are arranged on both sides of the buckle cover base, and the balance grooves are located below the connecting card plate and are connected to the drainage hole.
[0011] As a further solution of the utility model: the flap includes a connecting shaft, the side wall of the drainage groove is provided with a connecting groove for installing the connecting shaft, the connecting shaft is fixedly provided with an inclined flap for drainage, and the inclined flap is fixedly connected to a flat flap that cooperates with the outer end of the lower vertical plate.
[0012] As a further solution of the utility model: a plurality of counterweight blocks are arranged on one side of the flat baffle away from the lower vertical plate.
[0013] Beneficial effects of the utility model:
[0014] The connecting shaft of the flap is rotatably connected in the drainage buckle cover, and the flap is isolated from the outside world through the buckle cover base, so as to avoid the flap being unable to flip due to direct blowing of the outside wind, thereby blocking the drainage trough and causing abnormal drainage.
[0015] The inclined baffles can more conveniently drain the accumulated water from the gutter, and the outward-inclined inclined baffles can effectively guide the outdoor airflow to prevent the airflow from breaking open the inclined baffles and causing rainwater backflow, thereby stabilizing drainage and improving the wind and rain protection effects.
[0016] The setting of the counterweight block can use the weight of the accumulated water to flush the flap open to achieve drainage. When the drainage is completed, it can be reset under the action of the counterweight block to prevent outdoor wind from blowing into the room through the drainage groove, thus playing a windproof role.

[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 4 As shown in the figure, the present invention is a window sash drainage structure, including a lower vertical plate 1 and a drainage cover 4. The upper end of the lower vertical plate 1 is fixedly connected with a drainage bottom plate 2. A side edge of the drainage bottom plate 2 close to the lower vertical plate 1 is fixedly provided with an upper vertical plate 3. A drainage hole 301 is provided on the upper vertical plate 3. The lower end of the drainage hole 301 is flush with the upper end surface of the drainage bottom plate 2. The drainage cover 4 is detachably installed at the drainage hole 301. A drainage groove 43 for drainage is provided on the drainage cover 4. A flipping baffle 5 for preventing outdoor wind and rain from flowing back is installed in the drainage groove 43.
[0025] The drainage cover 4 includes a cover base 41 and a clamping convex block 42 fixedly provided on the cover base 41. The clamping convex block 42 penetrates through the drainage hole 301 and extends to the other side of the upper vertical plate 3. The drainage groove 43 is provided on the clamping convex block 42 and the cover base 41.
[0026] Specifically, the length and width of the cover base 41 are both greater than those of the clamping convex block 42, and the length and width of the cover base 41 are both greater than those of the drainage hole 301, which can block the drainage hole 301 to ensure the stable installation of the drainage cover 4, realize the outer limit of the installation of the drainage cover 4, and at the same time close the drainage hole 301 so that rainwater is discharged from the drainage cover 4, and prevent outdoor wind and rain from entering the room through the drainage hole 301, effectively ensuring the wind and rain prevention effect of the window sash.
[0027] Furthermore, the connecting convex block 42 is in a U-shaped structure. The side with an opening is used for opening the drainage groove 43, and the other three sides are all convex to ensure the stability of the connection and the blocking of the drainage hole 301.
[0028] Both sides of the clamping convex block 42 are fixedly provided with connecting clamping plates 45 for clamping and installing the drainage cover 4.
[0029] The setting of the connecting card plate 45 facilitates the installation of the drain buckle cover 4, and the connecting card plate 45 is an elastic structure, which facilitates the rapid disassembly and assembly of the drain buckle cover 4.
[0030] A plurality of support columns 47 are disposed at the drainage groove 43 on the clamping protrusion 42 . One end of the support column 47 is fixedly connected to the clamping protrusion 42 , and the other end of the support column 47 abuts against the drainage bottom plate 2 .
[0031] The provision of the support column 47 improves the overall strength of the drain buckle cover 4, thereby ensuring the installation stability and service life of the drain buckle cover 4.
[0032] Balancing grooves 44 are disposed on both sides of the buckle cover base 41 . The balancing grooves 44 are located below the connecting clamp plate 45 and are connected to the drainage hole 301 .
[0033] The arrangement of the balance tank 44 allows air pressure to circulate between the outdoors and indoors, 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.
[0034] The flap 5 includes a connecting shaft 51, and the side wall of the drainage groove 43 is provided with a connecting groove 46 for installing the connecting shaft 51. The connecting shaft 51 is fixedly provided with an inclined flap 52 for drainage, and the inclined flap 52 is fixedly connected with a flat flap 53 that matches the outer end of the lower vertical plate 1.
[0035] A plurality of counterweights 54 are disposed on one side of the flat baffle 53 away from the lower vertical plate 1 .
[0036] Specifically, the connecting shaft 51 of the flap 5 is rotatably connected in the drainage buckle cover 4, and the flap 5 is isolated from the outside world through the buckle cover base 41, so as to avoid that the flap 5 cannot be turned over due to the direct blowing of the outside wind, thereby blocking the drainage groove 43 and causing the failure of normal drainage. The inclined baffle 52 can be used to more conveniently discharge the accumulated water from the drainage groove 43, and the inclined baffle 52 inclined outward can effectively guide the outdoor airflow to prevent the airflow from breaking the inclined baffle 52 and causing the backflow of rainwater, thereby stabilizing the drainage and improving the wind and rain protection effects. The setting of the counterweight block 54 can break the flap 5 through the weight of the accumulated water to achieve drainage, and can be reset under the action of the counterweight block 54 after the drainage is completed, so as to prevent the outdoor wind from blowing into the room through the drainage groove 43, thereby playing a windproof role.
[0037] The working principle of the utility model is as follows: the connecting clamping plates 45 on both sides are pressed to insert the clamping protrusions 42 into the drainage holes 301. When the clamping protrusions 42 are fully inserted, the connecting clamping plates 45 on both sides rebound and reset, and the drainage buckle cover 4 is stably installed on the upper vertical plate 3. When rainwater falls on the drainage bottom plate 2, it then enters the drainage groove 36. The inclined baffle plate 52 can more conveniently discharge the accumulated water from the drainage groove 43. The outwardly inclined baffle plate 52 can effectively guide the outdoor airflow to prevent the airflow from breaking the oblique baffle plate 52 and causing the backflow of rainwater, thereby stabilizing the drainage and improving the wind and rain protection effects. The setting of the counterweight block 54 can break the flap 5 through the weight of the accumulated water to achieve drainage. When the drainage is completed, it can be reset under the action of the counterweight block 54 to prevent the outdoor wind from blowing into the room through the drainage groove 43, thereby playing a windproof role.
[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.
