Description

Technical Field

[0001] This utility model relates to the field of drainage cover technology, specifically a drainage cover structure for doors and windows. Background Technology

[0002] With the continuous development of the construction industry, people's requirements for the performance of doors and windows are increasing. As an important part of buildings, doors and windows not only need to have good heat insulation, sound insulation, and sealing performance, but also need to have reliable drainage functions. There are various types of door and window drainage structures commonly found on the market. Traditional door and window drainage methods mostly use simple drain outlet designs. Although this method can achieve drainage to a certain extent, it has many defects. For example, the drain outlet is easily blocked by dust and debris, resulting in poor drainage. Water accumulates inside the door and window, which in turn corrodes the hardware and frame structure of the door and window. Therefore, drainage covers are needed.

[0003] Some traditional drainage covers have complex structural designs and consist of many parts. Their assembly process requires tools such as screwdrivers, which makes them difficult for ordinary installers to operate. This not only increases the time cost of installation, but also makes it easy for the drainage cover to be damaged or not installed securely due to improper operation during installation, thus affecting the drainage effect. Therefore, a drainage cover structure for doors and windows is needed to solve the above technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage cover structure for doors and windows, which aims to solve the problems in the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a drainage cover structure for doors and windows, comprising:

[0006] Drain cover:

[0007] Multiple drainage holes are evenly distributed at the bottom of the drainage cover;

[0013] Preferably, the windshield clamping structure includes clamping blocks, clamping rods, clamping strips, overlapping blocks, and support positioning plates. There are two clamping blocks, symmetrically installed inside the drain cover. Each clamping block has a clamping hole on one side. There are two clamping rods, inserted into the clamping holes, with each rod corresponding to a specific hole. The clamping strip is connected to the ends of the two clamping rods. There are two overlapping blocks, symmetrically connected to one side of the clamping strip. Both overlapping blocks and the clamping strip have limiting grooves for limiting the position of the support rod. There are two support positioning plates, symmetrically installed inside the drain cover.

[0014] Preferably, the mounting and fixing structure includes positioning posts and screws. There are two positioning posts, which are symmetrically installed at the two corners of the drain cover.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 7As shown, a drainage cover structure for doors and windows includes a drainage cover 10. Multiple drainage holes 11 are evenly distributed on the bottom side of the drainage cover 10. A windbreak 20 is installed inside the drainage cover 10, with a gap between the windbreak 20 and the drainage cover 10 to facilitate rotation and drainage. The windbreak 20 is used to block the drainage outlets on the profile, and its size is larger than the size of the drainage outlets on the profile, enabling complete blocking. A windbreak support and positioning assembly is provided between the drainage cover 10 and the windbreak 20 to position the windbreak 20 inside the drainage cover 10. An installation and fixing structure 30 is provided on the drainage cover 10 to fix the drainage cover 10 to the profile. A windbreak clamping structure 40 is connected to the drainage cover 10 to clamp and fix the windbreak 20.

[0031] It should be noted that the bottom of the wind deflector 20 is sloping, and the bottom of the wind deflector 20 corresponds to the position of the drainage hole 11. The wind deflector 20 allows rainwater to be discharged quickly from the drainage hole 11. On rainy days, the wind deflector can prevent rainwater from flowing back in. In windy weather, if the wind blows back into the interior of the drainage cover 10, the wind deflector 20 will fit tightly against the profile under the action of wind pressure, preventing the wind deflector 20 from shaking. This also prevents the drainage cover structure from making abnormal noises during windy weather.

[0032] like Figure 4 and Figure 5 The wind deflector support and positioning assembly includes two support blocks 12 installed inside the drain cover 10 and support rods 21 connected to the two sides of the wind deflector 20. The two support blocks 12 are symmetrically distributed on one side inside the drain cover 10. Each of the two support blocks 12 has a support groove 13 on one side. The support rods 21 overlap inside the support grooves 13. The diameter of the support rods 21 is adapted to the width of the support grooves 13.

[0033] It is important to note that the interior of the wind deflector 20 and the support rod 21 must be smooth to ensure that the support rod 21 can rotate smoothly inside the support groove 13, avoiding burrs or other factors that may affect the rotation of the support rod 21. This ensures that the wind deflector 20 can rotate without touching the surface of the profile during drainage operations, creating a gap between the wind deflector 20 and the profile to ensure the normal operation of the drainage process.

[0034] like Figure 3 and Figure 6The windshield clamping structure 40 includes two clamping blocks 41 installed inside the drain cover 10. The two clamping blocks 41 are symmetrically distributed inside the drain cover 10. The clamping blocks 41 are in contact with the support blocks 12, and there is a one-to-one correspondence between the clamping blocks 41 and the support blocks 12. The clamping blocks 41 are located on the side of the support blocks 12 away from the center line of the drain cover 10. Each of the two clamping blocks 41 has a clamping hole 411 on one side. A clamping rod 42 is inserted into each of the two clamping holes 411. A clamping strip 43 is connected to the end of each of the two clamping rods 42. Two overlapping blocks 44 are fixedly connected to one side of 43. The overlapping blocks 44 and the clamping strip 43 are an integral structure. Limiting grooves 45 are opened on both overlapping blocks 44 and clamping strip 43. The limiting grooves 45 are used to limit the support rod 21. The support rod 21 is located between the limiting grooves 45 and the support groove 13. Two support positioning plates 46 are fixedly connected inside the drain cover 10. The overlapping blocks 44 overlap on the support positioning plates 46. The overlapping blocks 44 and the support positioning plates 46 correspond one-to-one. The support positioning plates 46 provide support force for the overlapping blocks 44.

[0035] It should be noted that the support positioning plate 46 is located below the support block 12 and is connected to the support block 12. The length of the support positioning plate 46 is greater than the length of the support block 12, which can provide a reserved overlapping space for the overlapping block 44. Furthermore, one side of the inner wall of the limiting groove 45 is arc-shaped, the limiting groove 45 is smooth, and the diameter of the arc surface is matched with the diameter of the support rod 21, so that the support rod 21 can rotate more smoothly.

[0036] like Figure 4 and Figure 5 The mounting and fixing structure 30 includes two positioning posts 31, which are symmetrically installed at the two corners of the drain cover 10. Each of the two positioning posts 31 has a screw hole 32 on one side, and the inner wall of each screw hole 32 is threaded with a screw 33.

[0037] When installing the drain cover 10 onto the door and window profile, two positioning holes with diameters matching the positioning posts 31 need to be drilled on the profile at positions corresponding to the drain outlets. Then, the positioning posts 31 are inserted into the positioning holes, and the screws 33 are threaded into the screw holes 32, ensuring the ends of the screws 33 fit tightly against the profile. This installs the drain cover 10 onto the door and window profile. A schematic diagram is shown below. Figure 1-2 As shown.

[0038] It is important to note that the maximum diameter of the end of the screw 33 is greater than the diameter of the positioning post 31. This ensures that the positioning post 31 will not move after the end of the screw 33 is tightly fitted with the profile, guaranteeing the positional stability of the positioning post 31 and the baffle 20. The positioning post 31 also prevents the support rod 21 from moving along the length of the drain cover 10, allowing the drain cover 10 to stably block the drain outlet. After the drain cover 10 is installed, the baffle 20 fits against the profile and corresponds to the position of the drain outlet, thus blocking the drain outlet. During drainage, the baffle 20 rotates under the action of water, allowing water to drain out through the gap between the baffle 20 and the profile. After drainage, the baffle 20 resets and blocks the drain outlet again.

[0039] like Figure 4 and Figure 7 A clearance arc groove 431 is provided on one side of the clamping strip 43. The inner wall of the clearance arc groove 431 fits against the inner wall of the positioning post 31. The diameter of the clearance arc groove 431 matches the diameter of the positioning post 31. The clearance arc groove 431 not only ensures that the clamping strip 43 can smoothly enter the interior of the drain cover 10, but also prevents the clamping strip 43 from moving along the length of the drain cover 10 through the clearance arc groove 431 and the positioning post 31, so that the clamping rod 42 can enter the interior of the clamping hole 411 more accurately.

[0040] Two limiting blocks 22 are fixedly connected to one side of the wind deflector 20, and an abutment post 14 is fixedly connected to one side inside the drain cover 10.

[0041] When the wind deflector 20 rotates, the limiting block 22 rotates accordingly. When the limiting block 22 contacts the inside of the drain cover 10, the wind deflector 20 contacts the abutment post 14. The limiting block 22 is used to ensure that the wind deflector 20 rotates at a large angle, thereby avoiding an excessive angle between the wind deflector 20 and the profile. This ensures normal drainage operation while preventing external water from entering the drain outlet.

[0042] The drain cover 10 is made of ADC12, and the wind deflector 20 and the clamping strip 43 are both made of POM.

[0043] The high hardness and strength of ADC12 give the drain cover 10 high structural strength, preventing damage to the drain cover 10. POM has high strength, wear resistance, high fatigue resistance and chemical corrosion resistance, making the wind deflector 20 and the clamping strip 43 less susceptible to corrosion, ensuring the service life of the wind deflector 20 and the clamping strip 43.

[0044] The working principle of this drainage cover structure is as follows:

[0045] 1) Position the support rod 21 inside the support groove 13. At this time, the positioning post 31 limits the support rod 21 to prevent it from moving.

[0046] 2) Place the positioning post 31 inside the relief arc groove 431, and move the clamping strip 43 along the direction of the positioning post 31 into the interior of the drain cover 10, so that the clamping rod 42 is inserted into the interior of the clamping hole 411. At this time, the support rod 21 is located inside the area formed by the limiting groove 45 and the support groove 13, and the support rod 21 is limited.

[0047] 3) The drainage cover 10 is installed on the door and window profile by the installation and fixing structure 30. At this time, the drainage outlet of the profile is blocked and protected by the drainage cover 10 and the wind deflector 20.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
