Description

Technical Field

[0001] The utility model relates to the field of door and window accessories, in particular to a drainage cover. Background Art

[0002] At present, in order to improve the sealing performance of windows, a convex rib is generally provided on the outer side of the window frame, and a sealing strip is provided between the window sash and the convex rib. Although this can play a certain sealing role, the sealing strip is prone to aging and the sealing effect is weakened after being used for a period of time. When a large amount of rainwater falls on the outer wall of the window sash and flows between the window sash and the convex rib, it is easy for rainwater to penetrate into the window frame inside the convex rib. In order to prevent rainwater from continuing to penetrate into the room, drainage holes are generally opened on the convex rib that penetrates through its inner and outer surfaces, so as to use the drainage holes to drain the rainwater inside the convex rib.

[0003] In order to improve the aesthetics and grade, and to reduce the impact of strong winds on the drainage of the drain holes, drain covers that cover the drain holes have appeared. In order to install the drain cover, a buckle is now separately provided on the inner wall of the drain cover, and the drain hole is buckled with the buckle to limit the drain cover on the drain hole. Among them, in order to avoid the convex rib being too abrupt and to control the manufacturing difficulty and manufacturing cost, the height of the convex rib is mostly controlled to be around 15mm, so the height of the convex rib is not high. Since the drain hole is generally opened on the lower side of the convex rib, the height of the drain hole is relatively low. In this way, the volume of the drain cover is relatively small, so the volume of the buckle provided on the drain cover will be smaller, which will result in the strength of the buckle buckle installation being very limited, and it is easy to be deformed and damaged when it hits the drain cover, which will easily affect the performance and life of the drain cover.

[0004] Therefore, it is very necessary to redesign the structure of the drain cover. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a windproof and automatic drainage drain cover which is one-piece formed without assembly and has high structural strength while facilitating manufacturing and controlling manufacturing costs, which can help to improve the stability and reliability of the installation and positioning of the drain cover, thereby greatly reducing the probability of deformation and damage caused by bumps, and further helping to maintain good performance for a long time, which can help to extend the service life.

[0006] The technical solution of the utility model is achieved in this way:

[0010] Preferably, the buckle hook includes a longitudinal bar, a limiting bar, and a connecting bar. The front end of the longitudinal bar is connected to the reinforcing protrusion. The limiting bar and the longitudinal bar are arranged side by side on the left and right, and the distance from the limiting bar to the longitudinal bar gradually decreases from the front to the back. The two ends of the connecting bar are respectively connected to the rear ends of the longitudinal bar and the rear ends of the limiting bar.

[0024] like Figures 1 to 4 As shown, the utility model describes an integrally formed windproof automatic drainage drain cover that does not require assembly, comprising a drain cover body 1, the inner wall of the drain cover body 1 is provided with at least one drainage hole 11 penetrating to the bottom surface thereof, the inner wall of the drain cover body 1 is provided with two L-shaped reinforcement protrusions 12, and the two reinforcement protrusions 12 are respectively located on the left and right sides of the drainage hole 11, and the two reinforcement protrusions 12 are respectively provided with buckle hooks 13.

[0025] On the drain cover, two L-shaped reinforcing protrusions 12 are arranged on the inner wall of the drain cover body 1, and the two reinforcing protrusions 12 are respectively located on the left and right sides of the drain hole 11, and buckle hooks 13 are respectively arranged on the two reinforcing protrusions 12. The reinforcing protrusions 12 can not only enhance the strength of the installation and positioning of the buckle hooks 13, but also can be used for embedded positioning, which can greatly enhance the accuracy, stability and reliability of the installation and positioning of the drain cover. And when the drain cover is bumped, the reinforcing protrusions 12 can play a very strong limiting role, so as to greatly reduce the probability of deformation and damage caused by bumps, and then can help to maintain good performance for a long time, which can help to extend the service life. The use of L-shaped reinforcing protrusions 12 can facilitate manufacturing while strengthening the structure, and this can also control the manufacturing cost very well.

[0026] like Figure 4 As shown, the reinforcing convex part 12 includes a vertical convex strip 121 and a transverse convex strip 122, one end of the vertical convex strip 121 is connected to one end of the transverse convex strip 122, and the other end of the vertical convex strip 121 is connected to the buckle hook 13. This can help the reinforcing convex part 12 to better play the role of restriction and reinforcement, thereby further improving the accuracy and stability of the installation and positioning of the drain cover, and further helping to further improve the reliability of the drain cover.

[0027] like Figure 4 As shown, the vertical ridge 121 is arranged on the edge of the drain hole 11, and the transverse ridge 122 is connected to one end of the side wall of the vertical ridge 121 away from the drain hole 11. This not only plays a very good limiting role, but also makes the drain cover have a compact and reliable structure, so that it can be installed on smaller holes, thereby further improving the application range of the drain cover.

[0028] like Figure 4 As shown, the buckle hook 13 includes a longitudinal strip 131 (the longitudinal direction is the front-to-back direction), a limiting strip 132, and a connecting strip 133. The front end of the longitudinal strip 131 is connected to the reinforcing protrusion 12. The limiting strip 132 and the longitudinal strip 131 are arranged side by side, and the distance from the limiting strip 132 to the longitudinal strip 131 is gradually reduced from the front to the back. The two ends of the connecting strip 133 are respectively connected to the rear end of the longitudinal strip 131 and the rear end of the limiting strip 132. In this way, the buckle hook 13 can not only have a high structural strength, but also facilitate the buckle hook 13 to be embedded, and can make the buckle hook 13 have a very strong buckle positioning effect, thereby helping to further improve the reliability and applicability of the drain cover.

[0029] like Figure 3 and Figure 4As shown, the front end surface of the limit strip 132 is a top pressing surface 1321, and the distance from the top pressing surface 1321 to the longitudinal strip 131 gradually increases from the front to the back. The use of such a top pressing surface 1321 can be beneficial to play a good top pressing role on window frame profiles of different thicknesses, so that even if there is a processing error in the window frame profile, the installation and positioning of the drain cover can be ensured to be very stable and reliable, thereby further improving the reliability and applicability of the drain cover.

[0030] like Figure 3 and Figure 4 As shown, the rear wall of the connecting strip 133 is connected to the side wall of the limiting strip 132 away from the longitudinal strip 131 in an arc transition. This can well meet the needs of embedding when a small hole is opened on the window frame profile, and can facilitate the embedding process to be smoother, thereby helping to improve the convenience of installation and positioning of the drain cover in this case.

[0031] like Figures 1 to 4 As shown, the two buckle hooks 13, the two reinforcing protrusions 12 and the drain cover body 1 are an integrally formed plastic structure. The drain cover can be integrally formed by core pulling, which does not require assembly, which not only facilitates batch production of drain covers, but also makes the drain cover have a more reliable structural strength, thereby helping to further improve the reliability of the drain cover.

[0032] like Figures 1 to 3 As shown, the two reinforcing protrusions 12 are arranged in a mirror-symmetrical relationship, and the two buckle hooks 13 are arranged in a mirror-symmetrical relationship. This can make the drain cover have a coordinated and stable structure, thereby further improving the accuracy, stability and reliability of the installation and positioning of the drain cover.

[0033] like Figure 4 As shown, the drainage hole 11 includes a longitudinal hole 111 and a trapezoidal hole 112 which is narrow at the top and wide at the bottom. The trapezoidal hole 112 is provided on the bottom surface of the drainage cover body 1, and the longitudinal hole 111 is provided on the rear wall of the drainage cover body 1, and the front end of the longitudinal hole 111 is connected to the upper end of the trapezoidal hole 112. In this way, a drainage hole 11 which is large outside and small inside can be formed, which not only makes the discharge of rainwater very smooth, but also makes the air flow in with greater resistance, thereby reducing the probability of rainwater backflowing due to wind force. The drainage cover can play an automatic drainage and windproof effect, which helps to further improve the reliability and applicability of the drainage cover.

[0034] like Figure 4 As shown, the rear hole wall and the left and right hole walls of the trapezoidal hole 112 are arranged vertically, and the left and right hole walls of the trapezoidal hole 112 are parallel to each other, and the front hole wall of the trapezoidal hole 112 is a plane with an upper end tilted backward. This not only facilitates molding and processing, but also enables the trapezoidal hole 112 to have a very good drainage effect, thereby helping to further improve the performance.

[0035] like Figure 1 As shown, the upper side and the left and right sides of the front wall of the drain cover body 1 are respectively provided with chamfered surfaces 14, and adjacent chamfered surfaces 14 are connected in a circular arc transition. This can not only reduce the use of raw materials, but also reduce the force of collision, so that the installation and positioning of the drain cover can maintain high stability and reliability for a long time.

[0036] like Figure 5 and Figure 6 As shown, before installing the drain cover, a rectangular mounting hole 102 is firstly opened on the convex rib 101 on the window frame 10; then the drain cover is arranged on the outer side of the convex rib 101; then two buckle hooks 13 are passed through the mounting hole 102 and buckled on the inner hole of the mounting hole 102, and two reinforcing protrusions 12 are embedded in the mounting hole 102. The lower hole edge of the longitudinal hole 111 is lower than the lower hole edge of the mounting hole 102, and the upper hole edge of the longitudinal hole 111 is higher than the upper hole edge of the mounting hole 102. In this way, the two reinforcing protrusions 12 can be used to enhance the stability and reliability of the installation and positioning of the drain cover, so as to greatly reduce the probability of deformation and damage caused by collision, and then it can be conducive to maintaining good performance for a long time, which can help to extend the service life.

[0037] like Figures 1 to 5 As shown, the longitudinal strip 131 is arranged on the lower end of the vertical convex strip 121, and the connecting strip 133 is arranged in a horizontal direction. The bottom surface of the vertical convex strip 121, the bottom surface of the longitudinal strip 131, the bottom surface of the limiting strip 132 and the bottom surface of the connecting strip 133 are on the same horizontal plane. The lower hole wall of the mounting hole 102 and the top surface of the window frame 10 are on the same horizontal plane, the bottom surface of the vertical convex strip 121 is pressed on the lower hole wall of the mounting hole 102, and the bottom surface of the longitudinal strip 131, the bottom surface of the limiting strip 132 and the bottom surface of the connecting strip 133 are all pressed on the top surface of the window frame 10. In this way, the reinforcing convex portion 12 and the buckle hook 13 can play a good supporting and positioning role, thereby further improving the stability and reliability of the installation and positioning of the drain cover.

[0038] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
