Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and in particular relates to a structure for enhancing the airtightness of doors and windows. Background Technology

[0002] The main function of the airtightness enhancement structure for doors and windows is to improve the sealing performance of doors and windows, prevent the penetration of external factors such as air, moisture, and dust, improve the energy efficiency and comfort of buildings, and enhance the tranquility of living or office environments.

[0003] Existing window and door airtightness enhancement structures leave gaps between the two windows after they are closed, allowing air to seep in, resulting in heat loss, cold air leakage, or external noise entering the room. This affects the stability and comfort of the indoor temperature. Furthermore, during heavy rain, rainwater may enter the room through the gaps, increasing maintenance costs. Additionally, rainwater can accumulate inside the window frame, exposing the sealing plate to a humid environment, causing it to age, swell, or deform, losing its elasticity and sealing effect.

[0004] To address these issues, we have developed an airtightness enhancement structure for doors and windows. Utility Model Content

[0005] The purpose of this utility model is to provide a door and window airtightness enhancement structure. By combining the water-draining component and the sealing component, it solves the problem in the prior art that when the window is closed, there is a gap between the two windows and the rainwater inside the window frame cannot be drained.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a structure for enhancing the airtightness of doors and windows, including a window frame. A first window is slidably connected to one side of the inner cavity of the window frame, and a second window is slidably connected to the other side of the inner cavity of the window frame. A water-draining assembly is provided inside the window frame, and the water-draining assembly includes a guide block. The guide block is fixedly connected to the inside of the window frame, and water-draining grooves are provided inside the guide block and on one side of the window frame to drain rainwater from inside the window frame. A sealing assembly is provided on one side of both the first and second windows, and the sealing assembly includes a sealing shell. The sealing shell is fixedly connected to one side of the first window, and an outer shell is fixedly connected to one side of the second window.

[0008] The present invention is further configured such that a spring is fixedly connected inside the outer shell, a movable plate is fixedly connected to one end of the spring, a first sealing plate is fixedly connected to one side of the movable plate, and a second sealing plate is fixedly connected to the surfaces of both the first window and the second window.

[0009] The present invention is further configured such that a sealing groove is provided inside the sealing shell, and the first sealing plate is slidably connected inside the sealing groove.

[0010] The present invention is further configured such that the material of the second sealing plate is EPDM, and the second sealing plate is used to increase the sealing performance between the first window and the second window and the window frame.

[0011] The present invention is further configured such that a sliding groove is provided on one side of the outer shell, and the second sealing plate is slidably connected inside the sliding groove.

[0012] The present invention is further configured such that there are seven springs, and their two ends are respectively fixedly connected to one side of the movable plate and one side of the inner wall of the outer shell.

[0013] The present invention is further configured such that the first sealing plate is made of silicone, and the first sealing plate is used to seal the gap between the first window and the second window.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model can move the outer shell by moving the second window, and the outer shell can move the first sealing plate. When the first sealing plate comes into contact with the sealing shell, the sealing shell will push the first sealing plate to move. The first sealing plate will push the moving plate to move. During the movement, the moving plate will squeeze the spring. When the first sealing plate coincides with the sealing groove, the spring will move the first sealing plate into the sealing groove through its own elasticity, thereby sealing the gap between the two windows.

[0016] 2. This utility model, through the setting of the water channel, can guide rainwater inside the window frame to the outside of the window frame, preventing water from seeping into the room and protecting the room from water leakage. Through the setting of the first sealing plate and the second sealing plate, the gap between the two windows can be filled to prevent air infiltration, thereby improving the airtightness of the doors and windows, reducing heat loss or cold air leakage, and improving energy efficiency.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model is a structure for enhancing the airtightness of doors and windows, including a window frame 1, a first window 2 slidably connected to one side of the inner cavity of the window frame 1, and a second window 3 slidably connected to the other side of the inner cavity of the window frame 1; a water-draining component is provided inside the window frame 1, the water-draining component includes a guide block 4, the guide block 4 is fixedly connected to the inside of the window frame 1, and a water-draining groove 5 is provided inside the guide block 4 and on one side of the window frame 1, through which rainwater inside the window frame 1 is drained; a sealing component is provided on one side of the first window 2 and the second window 3, the sealing component includes a sealing shell 6, the sealing shell 6 is fixedly connected to one side of the first window 2, and an outer shell 7 is fixedly connected to one side of the second window 3.

[0027] Specifically: the window frame 1 facilitates the installation of the first window 2 and the second window 3; the water channel 5 draws out rainwater from inside the window frame 1, preventing rainwater from accumulating inside the window frame 1 and corroding the second sealing plate 12, thus causing poor sealing; the sealing shell 6 facilitates subsequent sealing work; and the outer shell 7 facilitates the placement of the first sealing plate 10, increasing its practicality during use.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, a spring 8 is fixedly connected inside the outer shell 7, a movable plate 9 is fixedly connected to one end of the spring 8, a first sealing plate 10 is fixedly connected to one side of the movable plate 9, and a second sealing plate 12 is fixedly connected to the surfaces of the first window 2 and the second window 3. A sealing groove 11 is opened inside the sealing shell 6, and the first sealing plate 10 is slidably connected inside the sealing groove 11. The material of the second sealing plate 12 is EPDM. The second sealing plate 12 is used to increase the sealing performance between the first window 2 and the second window 3 and the window frame 1. A sliding groove 13 is opened on one side of the outer shell 7, and the second sealing plate 12 is slidably connected inside the sliding groove 13. There are seven springs 8, and their two ends are fixedly connected to one side of the movable plate 9 and one side of the inner wall of the outer shell 7, respectively. The material of the first sealing plate 10 is silicone. The first sealing plate 10 is used to seal the gap between the first window 2 and the second window 3.

[0030] Specifically: Spring 8 can move the movable plate 9 through its own elasticity, thereby increasing the convenience of use; the first sealing plate 10 can increase the sealing between the two windows; through the setting of the sealing groove 11 and the first sealing plate 10, the gap between the two windows can be sealed to prevent air infiltration; the second sealing plate 12 can increase the sealing performance between the first window 2 and the second window 3 and the window frame 1; silicone has excellent high temperature and low temperature resistance and good aging resistance, which can increase the sealing performance; EPDM has good aging resistance, UV resistance, ozone resistance and temperature difference resistance, and is suitable for outdoor environments, often used as an external sealing material.

[0031] The working principle of this utility model is as follows: When it is necessary to seal the gap between two windows, the user closes the windows. At this time, the first window 2 moves the sealing shell 6, the second window 3 moves the outer shell 7, and the outer shell 7 moves the first sealing plate 10. When the first sealing plate 10 contacts the sealing shell 6, the sealing shell 6 pushes the first sealing plate 10 to move. The first sealing plate 10 pushes the moving plate 9 to move. During the movement, the moving plate 9 will squeeze the spring 8. When the first sealing plate 10 coincides with the sealing groove 11, the spring 8 will use its own elasticity to move the first sealing plate 10 into the sealing groove 11, thereby sealing the gap between the two windows.

[0032] Furthermore, the water channel 5 can guide rainwater inside the window frame 1 to the outside of the window frame 1, which not only prevents water from seeping into the room, but also prevents rainwater from corroding the second sealing plate 12, thereby extending the service life of the second sealing plate 12.
