Description

Technical Field

[0001] This utility model relates to the field of system door and window technology, specifically a high airtight system door and window structure. Background Technology

[0002] System windows and doors are high-performance building window and door solutions that employ integrated design and precision manufacturing processes. Their core feature is that they achieve excellent sealing, heat insulation, sound insulation, and durability through the collaborative work of multiple component systems. System windows and doors mainly rely on rubber sealing strips to achieve air tightness, but they are prone to aging and deformation after long-term use, leading to air leakage through gaps. The air tightness is usually only 1.5-2.5m³ / (m·h), which is insufficient to prevent the exchange of hot and cold air and the penetration of wind noise.

[0003] In the prior art, a system door and window disclosed in patent publication number "CN209539062U" includes a frame, a mullion vertically provided inside the frame, and the frame is divided into a first window and a second window by the mullion. A sash frame is provided in the first window, and a fixed window is provided in the second window. The outer edge of the fixed window is connected to the inner edge of the frame through a first connector. The sash frame is a frame body, and glass is embedded in the inner edge of the sash frame. The sash frame includes a horizontal end and a vertical end. The horizontal end is connected to the inner edge of the frame through a second connector, and the vertical end is connected to the mullion through a third connector. Each of the first, second, and third connectors is provided with a rubber strip.

[0004] However, existing technologies still have significant shortcomings. Traditional doors and windows mainly rely on a single rubber sealing strip structure. Over long-term use, the sealing strip is prone to hardening and cracking due to repeated compression and ultraviolet radiation. This can easily lead to leakage gaps between the window sash and the window frame. As a result, traditional system doors and windows generally have poor airtightness after long-term use and cannot effectively block the flow of indoor or outdoor air when closed. Utility Model Content

[0005] The purpose of this invention is to provide a high airtightness system door and window structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high airtightness system door and window structure, including a frame and a sliding frame, wherein movable connecting rods are connected between the two sides of the sliding frame and the inner wall of the frame, a sealing strip is provided on the back of the frame, a magnetic serrated frame is fixed to the back of the frame with screws, a serrated block is arrayed on the front of the sliding frame, and the serrated groove on the magnetic serrated frame corresponds to the position of the serrated block, a blocking frame is provided in the opening on the front of the frame, and the blocking frame is located at the position of the magnetic serrated frame, a filling cavity is opened in the inner wall of the blocking frame, and an overlapping surface is provided on the front of the sliding frame, and the overlapping surface cooperates with the blocking frame.

[0007] As can be seen, in the above technical solution, the liquid seal and the magnetic serrated structure work together to achieve a double seal. When the push-pull frame is closed, the serrated block is precisely embedded in the groove of the magnetic serrated frame, forming a physical interlocking lock, directly blocking the straight air penetration path and improving air tightness. At the same time, it can fill the filling cavity of the blocking frame with liquid, such as deionized water or glycerin solution, to form an impenetrable liquid sealing layer, eliminating the possibility of gas penetration at the door and window frame.

[0008] Preferably, the sawtooth grooves and sawtooth blocks on the magnetic sawtooth frame are magnetically attracted to each other, and the sawtooth grooves and sawtooth blocks on the magnetic sawtooth frame are both sawtooth-shaped.

[0009] As can be seen, in the above technical solution, the magnetic serrated frame and the serrated blocks on the front of the sliding frame cooperate with each other, and the airtightness of the doors and windows is greatly improved through the dual effects of mechanical engagement and magnetic assistance.

[0010] Preferably, the front of the frame is provided with a replenishing cylinder and a receiving cylinder, and the blocking frame is located between the replenishing cylinder and the receiving cylinder.

[0011] As can be seen, in the above technical solution, the replenishing cylinder and the collecting cylinder are located at the beginning and end of the blocking frame, and both the replenishing cylinder and the collecting cylinder are liquid storage containers.

[0012] Preferably, the back of the replenishing cylinder and the collecting cylinder are fitted into the mounting groove on the front of the frame and fixed to the front of the frame by screws.

[0013] As can be seen, in the above technical solution, the replenishing cylinder and the receiving cylinder are fitted into the installation position, making the whole structure more aesthetically pleasing. At the same time, the exposed parts are convenient for users to operate and manually replenish the liquid.

[0014] Preferably, the replenishing cylinder is located above the receiving cylinder, and both the replenishing cylinder and the receiving cylinder are hollow cavities.

[0015] As can be seen, in the above technical solution, the replenishing cylinder is located at the top, and gravity can be used to allow the liquid to flow into the blocking frame through the connecting pipe during replenishment. Similarly, the receiving cylinder is located at the bottom, and gravity can also be used to allow the liquid in the blocking frame to enter the receiving cylinder.

[0016] Preferably, the connection between the replenishing cylinder and the receiving cylinder is provided with a connecting pipe, and one end of the connecting pipe is connected to the interface of the blocking frame.

[0017] As can be seen, in the above technical solutions, the connecting ends of the connecting pipes are all connected to the blocking frame, allowing liquid to enter the blocking frame or exit from the blocking frame.

[0018] Preferably, a circulation pipe is connected between the replenishing cylinder and the receiving cylinder, and the circulation pipe is located on both sides of the blocking frame.

[0019] As can be seen, in the above technical solution, a pump can be added to the replenishment cylinder and connected to the circulation pipe, so that the liquid in the collection cylinder can enter the replenishment cylinder from the circulation pipe and wait for use.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The magnetic serrated frame and the serrated blocks on the front of the sliding frame work together to significantly improve the airtightness of the doors and windows through the dual effects of mechanical engagement and magnetic assistance. When the sliding window is closed, the serrated blocks are precisely embedded in the grooves of the magnetic serrated frame, forming a physical interlocking lock that directly blocks the straight air penetration path and significantly increases air penetration resistance. At the same time, the permanent magnets built into the magnetic serrated frame generate a strong attraction force with the magnetic metal of the serrated blocks, further pressing the contact surface between the window frame and the frame, eliminating tiny gaps caused by processing tolerances or long-term use. This not only ensures an immediate sealing effect but also compensates for the performance degradation of the sealing strip after aging, maintaining high airtightness in the long term.

[0022] 2. After the sliding window is completely closed, liquid is injected into the filling cavity of the blocking frame through the liquid replenishment tube. The seamless flow of the liquid achieves airtight sealing. Under the action of gravity, the liquid automatically fills the filling cavity, forming an impenetrable liquid seal layer, eliminating the possibility of gas infiltration at the door and window frame. The liquid seal and the magnetic sawtooth structure work together to achieve double sealing, which greatly improves the airtightness of the door and window. When ventilation is required, the liquid flows back to the liquid collection tube by gravity and is circulated to the liquid replenishment tube by the water pump for later use, realizing recycling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] Example 1: A high airtightness system door and window structure: including a frame 1 and a sliding frame 2. Movable connecting rods 4 connect the two sides of the sliding frame 2 to the inner wall of the frame 1. A sealing strip 3 is provided on the back of the frame 1. The frame 1 and the sliding frame 2 are connected by the movable connecting rods 4. When the sliding frame 2 is pushed open or closed by the user, the movable connecting rods 4 move with the sliding frame 2 to complete the opening or closing. Simultaneously, the back of the frame 1 includes a sealing strip 3. The rubber sealing strip 3 can adhere to the sliding frame 2 after it is closed, achieving a basically good airtightness effect. A magnetic serrated frame 5 is screwed to the back of the frame 1. Serrated blocks 6 are arrayed on the front of the sliding frame 2, and the serrated grooves on the magnetic serrated frame 5 correspond to the positions of the serrated blocks 6. The serrated grooves on the toothed frame 5 and the serrated blocks 6 are magnetically attracted to each other, and both the serrated grooves on the magnetic serrated frame 5 and the serrated blocks 6 are serrated in shape. With long-term use, the sealing strip 3 is prone to wear or cracking, which leads to a decrease in air tightness. Therefore, a magnetic serrated frame 5 is added to the back of the frame 1. After the sliding frame 2 is closed, the serrated blocks 6 on the front are interlocked with the serrations on the magnetic serrated frame 5 to form a physical interlocking lock, directly blocking the straight air penetration path. The magnetic serrated frame 5 has a built-in permanent magnet, such as a neodymium iron boron magnet, which generates a strong attraction force with the magnetic metal of the serrated blocks 6, such as low carbon steel, further pressing the contact surface between the window frame and the frame 1, eliminating the small gaps caused by processing tolerances or long-term use, thereby improving the air tightness of the door and window after closing.

[0032] A blocking frame 7 is provided in the opening on the front of frame 1, and the blocking frame 7 is located at the position of the magnetic serrated frame 5. A filling cavity 8 is provided on the inner wall of the blocking frame 7. The front of the push-pull frame 2 has an overlapping surface 9, and the overlapping surface 9 cooperates with the blocking frame 7. A blocking frame 7 is added to the inner wall of frame 1 at the position corresponding to the magnetic serrated frame 5. The blocking frame 7 is aligned with the magnetic serrated frame 5, and the serrated groove on the magnetic serrated frame 5 is located in the blocking frame 7. The cavity inside the blocking frame 7 is the filling cavity 8, which is mainly used to fill liquids such as deionized water or glycerin solution. After the push-pull frame 2 is closed, the serrated groove part of the magnetic serrated frame 5 is closed. The overlapping surface 9 of the front of the sliding frame 2 is located in conjunction with the blocking frame 7. The sealing strip 3 on the inner wall of the blocking frame 7 can be used to seal the blocking frame 7 after the sliding frame 2 is closed. At this time, liquid is injected into the filling cavity 8, and the seamless flow of the liquid is used to achieve airtight sealing, forming an impenetrable liquid sealing layer, eliminating the possibility of gas infiltration at the edge of the sliding frame 2, achieving double sealing, blocking the free flow of air, preventing outdoor air such as cold wind, dust, and pollutants from irregularly seeping into the room, and preventing the meaningless loss of indoor warm and cold air such as the leakage of air conditioning heating, which significantly improves the airtightness.

[0033] The front of frame 1 is provided with a replenishing cylinder 10 and a receiving cylinder 11, and the blocking frame 7 is located between the replenishing cylinder 10 and the receiving cylinder 11. The backs of the replenishing cylinder 10 and the receiving cylinder 11 are fitted into the mounting grooves on the front of frame 1 and fixed to the front of frame 1 with screws. The replenishing cylinder 10 is located above the receiving cylinder 11, and both the replenishing cylinder 10 and the receiving cylinder 11 are hollow. Connecting pipes 12 are provided at the connection points of the replenishing cylinder 10 and the receiving cylinder 11, and one end of the connecting pipe 12 is connected to the interface of the blocking frame 7. A circulation pipe 13 is connected between the replenishing cylinder 10 and the receiving cylinder 11, and the circulation pipe 13 is located on both sides of the blocking frame 7. The front of frame 1 includes the replenishing cylinder 10 and the receiving cylinder 11. This is a semi-embedded installation to avoid affecting the overall aesthetics. The replenishing cylinder 10 is located at the top and the receiving cylinder 11 is located at the bottom. After the push-pull frame 2 is closed, the valve of the connecting pipe 12 at the replenishing cylinder 10 can be opened to allow the liquid to flow from the connecting pipe 12 into the filling chamber 8 under the influence of gravity, thus completing the filling of the liquid. Similarly, when it is necessary to open the push-pull frame 2, the valve of the connecting pipe 12 at the receiving cylinder 11 can be opened to allow the liquid to flow from the connecting pipe 12 into the receiving cylinder 11 under the influence of gravity. A sealing gasket can be added to the connection between the blocking frame 7 and the connecting pipe 12 for sealing. The replenishing cylinder 10 includes an extraction pump, which can draw the liquid in the receiving cylinder 11 back from the circulation pipe 13 to the replenishing cylinder 10 for recycling.

[0034] Working principle: The magnetic serrated frame 5 on the back of frame 1 and the serrated block 6 on the front of sliding frame 2 magnetically attract each other and cooperate, thereby improving the airtightness of the door and window after sliding frame 2 is closed. An interlocking frame 7 is added at the opening of frame 1. After the sliding window is closed, the overlapping surface 9 on the front of sliding frame 2 seals the interlocking frame 7. At the same time, the serrated block 6 cooperates with the magnetic serrated frame 5 to magnetically attract and seal the serrated groove at the magnetic serrated frame 5. At this time, the valve of the connecting pipe 12 on the liquid replenishment cylinder 10 can be opened, and the liquid can be injected into the filling cavity 8 in the interlocking frame 7 by gravity, thus blocking the liquid. Free airflow prevents outdoor air such as cold wind, dust, and pollutants from irregularly seeping into the room, while also preventing the meaningless loss of indoor warm and cold air, such as the leakage of air conditioning heating, thereby further improving the airtightness of doors and windows. Before opening the sliding window for ventilation, the valve of the connecting pipe 12 on the liquid collection cylinder 11 is opened. The liquid in the filling chamber 8 falls downward into the liquid collection cylinder 11 by gravity for recycling. The recycled liquid is then sent to the replenishment cylinder 10 through the circulation pipe 13 by a water pump, waiting for the next use, thus realizing recycling. The liquid can be replenished separately from the injection end in the liquid collection cylinder 11.
