Description

Technical Field

[0001] This utility model relates to the field of metal door and window technology, specifically to a drainage mechanism for metal door and window bases. Background Technology

[0002] The metal door and window base drainage mechanism is a drainage system specifically designed for metal doors and windows. It mainly consists of a base, baffle, guide rail, drain hole, inner cavity, and drain outlet. When the air pressure in the inner cavity is balanced with the outdoor air pressure, sewage is quickly discharged through the drain outlet under the action of gravity. If strong winds cause air pressure differences, the concealed drainage design can prevent rainwater backflow. The metal door and window base drainage mechanism is suitable for high-rise buildings, coastal and rainy areas, public buildings and commercial spaces, industrial plants, and other scenarios.

[0003] For example, Chinese patent CN218029746U, entitled "A Metal Door and Window Frame," includes a frame body and extension plates. Extension plates are fixedly installed on both sides of the frame body, near the top and bottom. A stop plate is fixedly installed on one end of the extension plate. A door is slidably installed inside the frame body. A cleaning scraper is movably embedded on the front surface of the frame body, near the sides. A pressure plate is movably installed on the front surface of the frame body, near the four corners. A knob is movably embedded on the front surface of the pressure plate. Door openings are longitudinally formed on both sides of the frame body. Furthermore, mounting grooves are longitudinally provided near both sides. Support plates are fixedly installed inside the mounting grooves near the upper and lower rear ends. Threaded rods are movably installed on the front surface of the support plates. A cross-shaped locking groove is provided on the front end face of the threaded rods. Inserts are provided on the front surface of the frame body, at the upper and lower ends of the mounting grooves. A spring-loaded groove is provided inside the frame body, behind the inserts. A reinforcing plate is fixedly installed on the front surface of the cleaning scraper. Threaded sleeves are fixedly installed on the upper and lower ends of the reinforcing plate. The cleaning scraper is embedded in the mounting grooves. Inserted posts are fixedly installed on the rear surface of the pressure plate near the four corners.

[0004] While the aforementioned existing technologies enable the use of metal doors and windows, in practical applications, it is difficult to seal the opening of the drainage chamber. The drainage chamber opening is typically left open, allowing insects and impurities to enter, increasing the risk of blockage. Furthermore, the drainage chamber is prone to producing noise, as the outlet is usually open and facing outwards. This means that strong winds combined with the drainage chamber can cause noise in the doors and windows, thus failing to meet current requirements. Therefore, we propose a drainage mechanism for metal door and window bases. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage mechanism for metal door and window bases to solve the problems mentioned in the background art, such as the difficulty in sealing the opening of the drainage cavity and the tendency of the drainage cavity to produce abnormal noise.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage mechanism for a metal door and window base, comprising a fixed frame, an installation cavity at the front end of the fixed frame, a drainage cavity at the center of the lower part of the fixed frame, the lower end of the drainage cavity being an inclined structure, a connecting cavity at the upper end of the fixed frame being connected to the drainage cavity, a first fixed rod being fixedly installed above the rear end of the drainage cavity, a rotating plate being installed at the center of the outer part of the first fixed rod, the rotating plate being rotatably connected to the first fixed rod, and the rotating plate corresponding to the lower opening of the drainage cavity.

[0007] Preferably, a torsion spring is provided on the outside of the first fixing rod located between the rotating plate and the side wall of the drainage cavity, and the two ends of the torsion spring are fixedly connected to the rotating plate and the side wall of the drainage cavity, respectively.

[0008] Preferably, a water outlet groove is provided at the lower front end of the fixed frame, which is connected to the drainage chamber. A second fixed rod is fixedly provided at the upper part of the water outlet groove. A baffle is sleeved on the outside of the second fixed rod. The baffle is rotatably connected to the second fixed rod, and the rear end of the baffle contacts the inner wall of the water outlet groove.

[0009] Preferably, a water collection tank is provided inside the upper end of the fixing frame of the connecting cavity, the water collection tank is connected to the connecting cavity, and a filter plate is provided inside the water collection tank, with the upper end of the filter plate located inside the water collection tank.

[0010] Preferably, magnetic strips are fixedly installed inside both the front and rear ends of the lower end of the filter plate, and the filter plate is attracted to the water collection tank by the magnetic strips.

[0011] Preferably, a mounting rod is fixedly provided on one side inside the mounting cavity, and a window frame is sleeved on the outside of the mounting rod, with the window frame rotatably connected to the mounting rod.

[0012] Preferably, two pieces of glass are fixedly installed inside the window frame, with a vacuum between the glass pieces.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can seal the opening of the drainage chamber by means of a rotating plate and a torsion spring. When it rains, the rainwater is filtered and collected in the connecting chamber. As the weight of the rainwater increases, the rotating plate rotates counterclockwise in the drainage chamber. At the same time, the torsion spring is in a compressed state. The rainwater enters the drainage chamber through the gap between the rotating plate and the connecting chamber. When the weight on the rotating plate is removed, the torsion spring resets, causing the rotating plate to rotate clockwise in the drainage chamber until the rotating plate is rotated to a suitable position. At this time, the upper end of the rotating rod is in a horizontal state, so that the rotating plate seals the opening of the drainage chamber, preventing mosquitoes and impurities in the environment from entering the drainage chamber.

[0015] (2) This utility model can seal the outlet of the drainage chamber by means of a baffle and a second fixing rod. When it rains, the rainwater collected in the drainage chamber will push the baffle to rotate clockwise in the water outlet channel. At this time, the rainwater flows out of the drainage chamber through the gap between the baffle and the water outlet channel. After the rainwater is discharged, the baffle rotates counterclockwise in the water outlet channel until the baffle returns to the vertical state. When encountering strong winds, the airflow acts on the baffle and blocks and seals the outlet of the drainage chamber, preventing the airflow from blowing directly into the drainage chamber, thereby reducing the noise of doors and windows.

[0016] (3) This utility model can filter impurities in rainwater through a filter plate and magnetic strip. When it rains, the rainwater is collected on the fixed frame to the opening of the water collection tank. At this time, the rainwater enters the drainage chamber through the connecting cavity. Before entering the connecting cavity, the filter plate filters the impurities in the rainwater, so that the impurities in the rainwater are intercepted by the filter plate, preventing the impurities from directly entering the drainage chamber through the connecting cavity. At the same time, when it is necessary to clean the filter plate, the filter plate can be directly removed from the water collection tank and cleaned. During installation, the lower end of the filter plate is aligned with the opening of the water collection tank and pushed into the water collection tank. At this time, the magnetic strip at the lower end of the filter plate is attracted to the inner wall of the water collection tank, thereby improving the convenience of disassembling and assembling the filter plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a drainage mechanism for a metal door and window base, comprising a fixed frame 1, an installation cavity 17 at the front end of the fixed frame 1, a drainage cavity 9 at the center of the lower part of the fixed frame 1, the lower end of the drainage cavity 9 being an inclined structure, an installation rod 2 fixedly installed on one side inside the installation cavity 17, a window frame 3 sleeved on the outside of the installation rod 2, the window frame 3 being rotatably connected to the installation rod 2, and two pieces of glass 4 fixedly installed inside the window frame 3, with a vacuum state between the glass 4.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The fixed frame 1 is located inside the upper end of the drainage cavity 9 and has a connecting cavity 16. The connecting cavity 16 is connected to the drainage cavity 9. A first fixed rod 11 is fixedly installed above the rear end of the drainage cavity 9. A rotating plate 12 is installed at the center of the outside of the first fixed rod 11. The rotating plate 12 is rotatably connected to the first fixed rod 11. The position of the rotating plate 12 corresponds to the lower opening of the drainage cavity 9. A torsion spring 13 is installed outside the first fixed rod 11 between the rotating plate 12 and the side wall of the drainage cavity 9. The two ends of the torsion spring 13 are fixedly connected to the rotating plate 12 and the side wall of the drainage cavity 9, respectively. The user can select a torsion spring 13 with appropriate elasticity according to the actual situation, so as to close the opening of the drainage cavity 9 through the rotating plate 12.

[0025] Please see Figure 1 , Figure 3 and Figure 4 A water outlet trough 7 is provided at the lower front end of the fixed frame 1. The water outlet trough 7 is connected to the drainage chamber 9. A second fixed rod 14 is fixedly provided at the upper part of the water outlet trough 7. A baffle 8 is sleeved on the outside of the second fixed rod 14. The baffle 8 is rotatably connected to the second fixed rod 14, and the rear end of the baffle 8 contacts the inner wall of the water outlet trough 7, so as to block the outlet of the drainage chamber 9 through the baffle 8.

[0026] Please see Figure 1 and Figure 4The fixed frame 1 is located inside the upper end of the connecting cavity 16 and has a water collection tank 5. The water collection tank 5 is connected to the connecting cavity 16. The water collection tank 5 has a filter plate 6 inside. The upper end of the filter plate 6 is located inside the water collection tank 5. Magnetic strips 15 are fixedly installed inside the lower end of the filter plate 6 at both the front and rear ends. The filter plate 6 is attracted to the water collection tank 5 by the magnetic strips 15, which facilitates the filtration of impurities in the rainwater through the filter plate 6.

[0027] Working principle: During use, rainwater collects on the fixed frame 1 at the opening of the water collection trough 5. The rainwater then enters the drainage chamber 9 through the connecting cavity 16. Before entering the connecting cavity 16, the filter plate 6 filters impurities from the rainwater. To clean the filter plate 6, simply remove it from the water collection trough 5. During installation, align the lower end of the filter plate 6 with the opening of the water collection trough 5 and push it in. The magnetic strip 15 at the lower end of the filter plate 6 adheres to the inner wall of the water collection trough 5. After the rainwater is filtered and collected in the connecting cavity 16, the weight of the rainwater causes the rotating plate 12 to rotate counterclockwise in the drainage chamber 9. Simultaneously, the torsion spring 13 is compressed, allowing the rainwater to pass through... The gap between the rotating plate 12 and the connecting cavity 16 leads into the drainage cavity 9. At this time, the weight on the rotating plate 12 is removed, and the torsion spring 13 resets, causing the rotating plate 12 to rotate clockwise in the drainage cavity 9 until it is rotated to a suitable position, thus sealing the opening of the drainage cavity 9. At this time, the rainwater collected in the drainage cavity 9 will push the baffle 8 to rotate clockwise in the water outlet 7. The rainwater will then flow out of the drainage cavity 9 through the gap between the baffle 8 and the water outlet 7 until the rainwater is discharged. Then, the baffle 8 rotates counterclockwise in the water outlet 7 until it returns to a vertical position. When encountering strong winds, the airflow acts on the baffle 8, blocking and sealing the outlet of the drainage cavity 9.

[0028] 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.
