For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figures 1 to 6 As shown, a door and window floor drain cover 100 according to an embodiment of the utility model comprises a rubber sleeve 10, a drain box 20, a baffle 30, and a cover plate 40; and is used to achieve drainage of doors and windows.

[0045] See also Figure 2 and Figure 3 The rubber sleeve 10 is provided with a cavity 11 with an opening on one side, and a water inlet hole 12 connected to the cavity 11 is provided on the rubber sleeve 10; in the present embodiment, the water inlet hole 12 is an oblong hole, which enlarges the area to increase the drainage volume and improve the service life of the doors and windows; the rubber sleeve 10 is provided with an opening (not marked in the figure) connected to the cavity 11 on the side facing the cover plate 40, and the rubber sleeve 10 extends with an annular flange 13 around the opening; when the cover plate 40 is assembled and connected with the drainage box 20, the annular flange 13 fits with the cover plate 40.

[0046] See also Figures 2 to 6 The drain box 20 is assembled in the cavity 11, and an elastic pressing block 21 is arranged below the drain box 20. One end of the elastic pressing block 21 that is away from the drain box 20 protrudes from the front end surface of the drain box 20. When the drain box 20 is assembled into the rubber sleeve 10, the elastic pressing block 21 elastically abuts and squeezes the inner wall of the cavity 11, so as to realize the fixed connection between the drain box 20 and the rubber sleeve 10. A drain cavity 22 is arranged inside the drain box 20, and a water leakage hole 23 and a water outlet 24 that are connected to the drain cavity 22 are arranged on the drain box 20. The water leakage hole 23 and the water outlet 24 are arranged at the two ends of the drain cavity 22 respectively, and the water leakage hole 23 and the water inlet 12 are aligned with each other. An abutting surface 25 is arranged in the drain cavity 22, and the abutting surface 25 is a curved surface with an inclination. The drainage cavity 22 is provided with connection grooves 26 symmetrically distributed on both sides of the abutment surface 25, and the water outlet 24 is provided with a through hole 27 connected to the connection groove 26; the inner side of the through hole 27 is provided with a first connection surface 271 with an arc surface. Rotation grooves 29 are also symmetrically provided on the inner side of the drainage cavity 22. The water leakage holes 23 are evenly arranged laterally on the upper end surface of the drainage box 20, which play a role in blocking debris and preventing debris from entering the drainage cavity 22 from the water leakage holes 23 and causing blockage.

[0047] Specifically, a notch 28 is provided at the lower end of the drainage cavity 22, and an elastic pressing block 21 is arranged in the notch 28, and the elastic pressing block 21 is in the structure of a cantilever beam. The elastic pressing block 21 includes a lower pressing arm 211 and an extension arm 212, and the bottom of the lower pressing arm 211 protrudes from the bottom surface of the drainage box 20. In this embodiment, the lower pressing arm 211 is arranged in a U shape in a natural state. When the elastic pressing block 21 squeezes the rubber sleeve 10, the arc bottom surface of the lower pressing arm 211 and the inner wall of the rubber sleeve 10 abut against each other and deform, thereby each generating an elastic force to promote close fixation to each other. The arc bottom surface of the lower pressing arm 211 can also play a role in preventing the inner wall of the rubber sleeve 10 from being scratched.

[0048] See also Figure 2 and Figure 3 , the baffle 30 is rotatably connected to the drainage cavity 22. A rotating shaft 31 is provided on the baffle 30, and the rotating shaft 31 is rotatably connected to the rotating groove 29 to realize the flipping of the baffle 30; further, a limiting protrusion 291 is provided inside the rotating groove 29, and the limiting protrusion 291 is used to limit the rotating shaft 31 to prevent the rotating shaft 31 from being separated from the rotating groove 29 and affecting normal use. A curved wall 32 is provided at one end of the baffle 30 facing the abutting surface 25; the shape of the curved wall 32 matches the curved surface, and when the baffle 30 abuts against the abutting surface 25, the baffle 30 can be completely fitted with the abutting surface 25.

[0049] When the baffle 30 turns toward the water outlet 24, Figure 8 As shown, the drainage cavity is in the second working state, and the drainage cavity 22 is in the open and closed state, which can realize the drainage of doors and windows. Figure 7 As shown, the drainage cavity is in the first working state, the baffle 30 will abut against the abutting surface 25, and thus cannot be turned over, so that the drainage cavity 22 is in a closed state to prevent outdoor water from flowing back.

[0050] See also Figure 2 and Figure 3, the cover plate 40 is provided with a drain hole 41 corresponding to the water outlet 24. One end of the cover plate 40 facing the drain box 20 is provided with connecting blocks 42 symmetrically distributed on both sides of the drain hole 41. A convex block 421 extends from the side surface of the connecting block 42; the convex block 421 is provided with a second connecting surface 423 with an arc surface, and the second connecting surface 423 is used to cooperate with the first connecting surface 271 to improve the assembly accuracy. The convex block 421 passes through the through hole 27 and is clamped in the connecting groove 26 to realize the assembly connection between the cover plate 40 and the drain box 20. When the convex block 421 moves to the bottom of the connecting groove 26, the connecting block 42 locks the elastic pressing block 21. A clearance groove 422 is provided at the bottom of the connecting block 42, and the clearance groove 422 is used to cooperate with the elastic pressing block 21. When the convex block 421 moves to the bottom of the connecting groove 26, that is, when the cover plate 40 is completely installed in the drain box 20, the clearance groove 422 fits with the elastic pressing block 21. The drain holes 41 are arranged horizontally and uniformly on the cover plate 40, which plays a role in blocking sundries and preventing sundries from entering the drain cavity 22 through the drain holes 41 and causing blockage.

[0051] The door and window floor drain drainage cover 100 of the present utility model has the function of one-way drainage, discharging the accumulated water in the door and window system, and at the same time preventing outdoor rainwater from flowing back.

[0052] The specific working principle is as follows: As Figure 9 shown, the door and window floor drain drainage cover 100 is assembled in the door and window frame 200. As Figure 8 shown, when there is accumulated water in the door and window frame 200, the accumulated water flows from the water leakage hole 23 towards the water outlet 24. At this time, the accumulated water pushes the baffle 30 to flip towards the water outlet 24, and then the drain cavity 22 is in an open and closed state to discharge the accumulated water. As Figure 7 shown, when there is accumulated water outdoors, the accumulated water enters the drain cavity 22 and applies a thrust towards the water leakage hole 23 to the baffle 30. At this time, the baffle 30 abuts against the abutting surface 25 and cannot be flipped, and then the drain cavity 22 is in a closed state, and the outdoor accumulated water cannot enter the room through the drain cavity 22, preventing rainwater from flowing back.

[0053] In addition, the door and window floor drain drainage cover 100 of the present utility model has the function of quick disassembly and replacement.

[0054] During specific assembly, as Figure 9As shown in the figure, align the bump 421 with the through hole 27, horizontally push the cover plate 40, and the bump 421 enters the connection groove 26 horizontally through the through hole 27; vertically move the cover plate 40 downward, and the bump 421 moves vertically downward along the connection groove 26 to the bottom of the connection groove 26; at this time, the connection block 42 is in contact with the elastic pressing block 21, so that the lower end of the elastic pressing block 21 protrudes from the bottom surface of the drainage box 20; during the above assembly process, since one end of the elastic pressing block 21 protrudes from the drainage box 20, when the cover plate 40 is assembled into the drainage box 20, the cover plate 40 will squeeze the elastic pressing block 21, and the elastic pressing block 21 will deform accordingly. After deformation, the lower end of the elastic pressing block 21 will protrude from the bottom surface of the drainage box 20. At the same time, the connection block 42 is located in the connection groove 26 to prevent the cover plate 40 from moving in the length direction of the elastic pressing block 21, thereby continuously squeezing the elastic pressing block 21. Push the drainage box 20 into the rubber sleeve 10, and the elastic pressing block 21 abuts against and squeezes the rubber sleeve 10; finally, install the door and window floor drain drainage cover 100 into the slot 300 of the door and window frame 200, and the elastic pressing block 21 can abut against the slot 300 to complete the assembly.

[0055] Conversely, when disassembly and replacement are required, as Figure 10 shown in the figure, push the cover plate 40 upward to separate the connection block 42 from the elastic pressing block 21; horizontally remove the cover plate 40 so that the cover plate 40 is separated from the drainage box 20; after the cover plate 40 is separated from the drainage box 20, the degree of deformation of the elastic pressing block 21 decreases. Move the elastic pressing block 21 upward so that the elastic pressing block 21 does not squeeze the rubber sleeve 10, and at the same time, there is no interference between the drainage box 20 and the slot 300, so that the drainage box 20 and the rubber sleeve 10 can be separated from the slot 300 of the door and window frame 200.

[0056] Compared with the prior art, the door and window floor drain drainage cover 100 of the present invention includes a rubber sleeve 10, a drainage box 20, a baffle 30 and a cover plate 40; wherein the baffle 30 is arranged in the drainage box 20 to flip unidirectionally to realize the unidirectional drainage of the drainage box 20, drain the accumulated water inside the door and window, and at the same time prevent the outside water from flowing back into the room; in addition, the rubber sleeve 10 is sleeved on the outside of the drainage box 20 to protect the drainage box 20 and prevent aging, and improve the service life; an elastic pressing block 21 is arranged in the drainage box 20. After assembly, the cover plate 40 can squeeze the elastic pressing block 21 to deform the elastic pressing block 21. The lower end of the elastic pressing block 21 protrudes from the drainage box 20 to squeeze the rubber sleeve 10 to deform, and then abuts against the door and window frame 200 to realize locking; at the same time, the deformation of the rubber sleeve 10 can abut against the notch of the door and window frame 200 to prevent gaps from causing rainwater side leakage; remove the cover plate 40 and move the elastic pressing block 21 upward so that the rubber sleeve 10 is reset and separated from the door and window frame 200, thereby quickly disassembling the rubber sleeve 10 and the drainage box 20, effectively solving the problems of installation and replacement.

[0057] The above only expresses the preferred technical solutions of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and the present utility model also intends to include these changes and variations.
