Description

Technical Field

[0001] This invention relates to the technical field of door and window structures, and particularly to a door and window structure with good sealing performance. Background Technology

[0002] As an important component of building envelope, the sealing performance of doors and windows directly affects the building's thermal insulation, waterproofing, sound insulation, and energy-saving effects. It is one of the core indicators for measuring the quality of door and window products. With the continuous improvement of building energy-saving standards and the increasing demands of users for living comfort, the defects of traditional door and window structures in terms of sealing performance, structural stability, and ease of operation and maintenance have gradually become prominent, making it difficult to meet the needs of actual applications.

[0003] Chinese Patent Publication No. CN222436182U discloses a PVC-U door and window structure with good sealing performance, including a PVC-U door and window frame. A PVC-U movable window is movably connected to one side of the inner wall of the PVC-U door and window frame. A fixed transparent glass is fixedly connected to the inner wall of the PVC-U movable window. A sealing mechanism is detachably connected to the outer wall of the PVC-U movable window. This device enhances the sealing effect between the PVC-U door and window frame and the PVC-U movable window through the sealing mechanism and the sealing strip body. The sealing strip body is easy to install and disassemble or replace. The operator can position the device by inserting the inner positioning connecting strip into the inner positioning connecting groove and then using the positioning anti-detachment block to insert into the positioning anti-detachment hole. The tension of the elastic element and the damper pushes the positioning anti-detachment block outward, thus firmly locking it into the positioning anti-detachment hole, making it difficult to detach or loosen. However, in actual use, the sealing design of the door and window structure adopts a single seal or a simple multi-layer superimposed seal, with a single sealing level and incomplete sealing coverage. For example, most doors and windows only rely on a single rubber strip at the joint between the frame and the sash to achieve sealing. They lack targeted sealing measures for key leakage paths such as the four corner gaps and the upper and lower side gaps between the fixed frame and the window frame. This allows external airflow and rainwater to easily enter the room through unsealed or weakly sealed areas, making it difficult to meet high-level requirements for air tightness and water tightness. At the same time, existing sealing structures mostly focus only on the "sealing" function and are not designed in conjunction with the "fixing" function of doors and windows. After the doors and windows are closed, the frame and sash are prone to shaking and displacement due to wind pressure, vibration and other factors, which leads to poor sealing and increases the risk of sealing failure. Summary of the Invention

[0004] The main objective of this invention is to provide a door and window structure with good sealing performance, which can effectively solve the problem that the sealing design of door and window structures uses a single seal or a simple multi-layer superimposed seal, resulting in a single sealing level and incomplete sealing coverage.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this invention, a two-stage sealing design is adopted. Initial sealing is achieved by the fit of sealing frame one and sealing frame two. Then, deep sealing is completed through the coordinated action of the driven device, sealing device one, and sealing device two, forming multiple protections. At the same time, sealing element one, sealing element two, and sealing element three are used to cover the side, top and bottom, and four corner gaps between the fixed frame and the window frame in an all-round way, completely blocking the leakage path of the gaps and significantly improving the core sealing indicators such as air tightness and water tightness.

[0022] 2. In this invention, the sealing mechanism, sealing device one, and sealing device two achieve sealing while simultaneously fixing the fixed frame and window frame by fitting and locking the sealing element with the fixed frame and window frame, thus preventing shaking and displacement after the door and window are closed, and taking into account both sealing reliability and structural stability.

[0023] 3. In this invention, the driven device, sealing device one, and sealing device two all adopt a modular structure design, and each component has detachable characteristics. At the same time, connecting part one and connecting part two achieve quick sealing and docking through a magnetic ring. The inspection and replacement of components can be completed without complicated tools, which greatly reduces the difficulty of maintenance operations and improves daily operation and maintenance efficiency.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1

[0042] like Figure 1 - Figure 5 As shown, this embodiment discloses a door and window structure with good sealing performance, including a mounting frame 1. Fixed frames 2 are provided on both sides of the inner cavity of the mounting frame 1. A central window 4 is provided in the middle of the inner cavity of the mounting frame 1. Window frames 3 are rotatably installed on the outer surfaces of the two fixed frames 2. A transmission mechanism 5 is provided on the side of the outer surface of the two window frames 3 that is close to each other. A driven device 6 is provided on one side of the inner cavity of the two fixed frames 2. A sealing device 8 is provided on the other side of the inner cavity of the two fixed frames 2. A sealing device 7 is provided on the upper and lower sides of the inner cavity of the two fixed frames 2.

[0043] Furthermore, such as Figure 6 As shown, a sealing frame 21 is provided around the inner surface of the fixed frame 2.

[0044] Furthermore, such as Figure 6As shown, the window frame 3 includes four L-shaped mounting brackets 31. Each of the four L-shaped mounting brackets 31 has a mounting cavity 32 inside. Each of the four L-shaped mounting brackets 31 has a sealing frame 2 33 on its outer surface. The driven device 6, two sealing devices 1 7 and sealing device 2 8 are installed in the inner cavity of the mounting cavity 32 in the four L-shaped mounting brackets 31.

[0045] Specifically, when the window needs to be closed, the operator holds the transmission mechanism 5 to drive the window frame 3 to rotate, so that the sealing frame 23 on the four L-shaped mounting brackets 31 fits against the outer surface of the fixed frame 2. During this process, the sealing frame 21 fits against the outer surface of the L-shaped mounting bracket 31 simultaneously, thereby achieving a preliminary seal.

[0046] Furthermore, after completing the above actions, the operator rotates the transmission mechanism 5 downwards, driving the driven device 6 to move. Through the internal components of the driven device 6, the two sealing devices 7 and 8 work together to make the relevant components of the driven device 6, the two sealing devices 7 and 8 fit tightly against the inner surface of the fixed frame 2. The secondary sealing is completed through the coordinated action of the three.

[0047] Furthermore, the two-stage sealing design significantly improves the overall sealing performance. Meanwhile, the driven device 6, the two sealing devices 7 and 8 adopt a modular design and are detachable, which facilitates daily inspection and replacement by maintenance personnel and improves maintenance efficiency.

[0048] In order to seal the space on one side of the window frame 3 and the fixed frame 2, and at the same time, to drive the two sealing devices 7 and 8, such as... Figure 7 and Figure 8 As shown, the driven device 6 includes a mounting shell 61, which is fixedly installed in the inner cavity of the mounting cavity 32. A fixing groove is provided in the middle of the outer surface of the mounting shell 61. A driven mechanism 62 is provided in the middle of the inner cavity of the mounting shell 61. A rack 63 is provided on both sides of the outer surface of the driven mechanism 62 and is slidably installed on the inner surface of the mounting shell 61. A hydraulic component 64 is fixedly installed on the inner surface of the mounting shell 61 at the ends of the two racks 63 that are far apart from each other. An oil guide component 66 is provided at the output end of the two hydraulic components 64. A sealing mechanism 65 is slidably installed on one side of the inner cavity of the mounting shell 61.

[0049] Specifically, when the operator rotates the transmission mechanism 5, the transmission mechanism 5 drives the driven mechanism 62 to rotate through the limit block 54. During the rotation of the driven mechanism 62, the sealing mechanism 65 is pushed to move, so that the sealing mechanism 65 is in contact with the inner surface of the window frame 3, thereby achieving the sealing function. During this process, the driven mechanism 62 synchronously drives the racks 63 on both sides to slide along the preset trajectory. The two racks 63 push the two hydraulic components 64 to move, so that the hydraulic oil in the inner cavity of the hydraulic component 64 is transported to the sealing device 7 on the upper and lower sides through the oil guide 66. At the same time, the hydraulic oil in the inner cavity of the hydraulic component 64 is synchronously transported to the inner cavity of the sealing mechanism 65.

[0050] In order to drive the driven mechanism 62 to rotate, such as Figure 9 As shown, the transmission mechanism 5 includes a handle 51 and a connecting cylinder 52. The connecting cylinder 52 is rotatably mounted on the outer surface of the fixed frame 2. A connecting rod 53 is provided on the end face of the handle 51. The connecting rod 53 is rotatably mounted in the middle of the connecting cylinder 52. A spring is provided between the outer surface of the connecting rod 53 and the inner cavity surface of the connecting cylinder 52. A limit block 54 is provided on the end face of the connecting rod 53. A limit groove is formed in the middle of the outer surface of the limit block 54.

[0051] In order to drive the sealing mechanism 65 and the rack 63 to move, such as Figure 9 As shown, the driven mechanism 62 includes a connecting handle 621, which is slidably installed in the inner cavity of the mounting housing 61. A gear 622 is provided on one side of the middle of the outer surface of the connecting handle 621. The gear 622 meshes with two racks 63. A pushing block 623 is provided on the other side of the middle of the outer surface of the connecting handle 621. The pushing block 623 is adapted to the sealing mechanism 65. A fixing block 624 is provided on the side of the outer surface of the connecting handle 621 away from the transmission mechanism 5. The fixing block 624 is adapted to the fixing groove. A positioning groove is provided on the end face of the connecting handle 621 near the transmission mechanism 5. A rubber ring is provided in the middle of the inner cavity of the positioning groove. A limiting block 54 is adapted to the positioning groove, and the limiting groove on the limiting block 54 is adapted to the rubber ring.

[0052] Specifically, the operator holds the handle 51 to drive the window frame 3 to rotate. After the window frame 3 is in contact with the surface of the fixed frame 2, the operator rotates the handle 51, which drives the limiting block 54 via the connecting rod 53. The limiting block 54, in conjunction with the positioning groove of the connecting handle 621, drives the connecting handle 621 to rotate. When the connecting handle 621 rotates, it drives the gear 622 and the pushing block 623 to rotate synchronously. This causes the gear 622 to drive the racks 63 on both sides to move, and the pushing block 623 to drive the sealing mechanism 65 to move. When the handle 51 rotates 90°, the fixing block 624 engages with the fixing groove in the middle of the mounting shell 61. At this time, the spring on the outer surface of the connecting rod 53 drives the connecting rod 53 and the handle 51 to move. Through the transmission of the connecting handle 621, the fixing block 624 is embedded into the inner cavity of the fixing groove, thus completing the limiting and positioning of the connecting handle 621.

[0053] Furthermore, when it is necessary to open the window, the operator must first pull the handle 51 outward, and the connecting rod 53 and the limiting block 54 will drive the connecting handle 621 to move outward, so that the fixing block 624 is disengaged from the inner cavity of the fixing groove. At this time, the operator can rotate the handle 51 90° in the opposite direction.

[0054] Furthermore, when the connecting rod 53 pulls the connecting handle 621 outward through the limiting block 54, the limiting groove on the limiting block 54 and the rubber ring in the inner cavity of the positioning groove can ensure the stability of the movement of the connecting handle 621 pulled by the limiting block 54. At the same time, when it is necessary to replace the driven device 6, the operator can apply a pulling force to the handle 51 to make the limiting block 54 disengage from the inner cavity of the positioning groove of the connecting handle 621.

[0055] In order to seal the space between the fixed frame 2 and the window frame 3, such as Figure 10 As shown, the sealing mechanism 65 includes a sealing plate 651, which is slidably installed in the middle of the inner cavity of the mounting shell 61. One end of the sealing plate 651 extends to the outside of the mounting shell 61. The sealing plate 651 is adapted to be used with the push block 623. Both ends of the sealing plate 651 are provided with sealing elements 652, and both sides of the outer surface of the sealing plate 651 are provided with elastic telescopic rods 653.

[0056] Furthermore, such as Figure 11 As shown, the sealing element 652 includes a sealing block 6521, which is fixedly installed on the end face of the sealing plate 651. A hydraulic cylinder 6522 is provided in the middle of the inner cavity of the sealing block 6521, and a piston 6523 is provided in the middle of the inner cavity of the hydraulic cylinder 6522. A connecting rod 6524 is provided on one side of the inner cavity of the sealing block 6521, which extends to the outside of the sealing block 6521. A spring 2 is provided between the end face of the piston 6523 and the end face of the connecting rod 6524. The inner cavity of the hydraulic cylinder 6522 is connected to the ventilation hydraulic pipe of the corresponding hydraulic element 64. A sealing strip 6525 is provided on one side of the outer surface of the connecting rod 6524 and is slidably installed on the inner surface of the sealing block 6521.

[0057] Specifically, when the transmission mechanism 5 drives the driven mechanism 62 to rotate, the push block 623 in the driven mechanism 62 pushes the sealing plate 651 to move outward, so that the sealing plate 651 fits against the inner surface of the window frame 3 to achieve the sealing function. During this process, the elastic telescopic rod 653 undergoes tensile deformation.

[0058] Furthermore, during the process of pushing the sealing plate 651, the hydraulic oil in the hydraulic component 64 is delivered to the inner cavity of the hydraulic cylinder 6522. The hydraulic oil entering the inner cavity of the hydraulic cylinder 6522 drives the piston 6523 to move. Since the sealing plate 651 has not yet adhered to the inner surface of the window frame 3, the sealing strip 6525 is blocked by the inner wall of the fixed frame 2 and cannot slide out from the inner wall of the sealing block 6521. The piston 6523 simultaneously compresses the spring 2 between itself and the connecting rod 6524. After the sealing plate 651 adheres to the inner surface of the window frame 3, the spring 2 releases its elastic potential energy and pushes the sealing strip 6525 to move outward.

[0059] Furthermore, after the sealing plate 651 and the sealing element 652 are pushed into place, they simultaneously adhere to the inner surface of the window frame 3, achieving a seal while simultaneously fixing the fixed frame 2 and the window frame 3 to each other.

[0060] Furthermore, when the window needs to be opened, the operator rotates the transmission mechanism 5 in the opposite direction, and the hydraulic oil in the inner cavity of the hydraulic cylinder 6522 is drawn back into the inner cavity of the hydraulic component 64. At this time, the connecting rod 6524 drives the sealing strip 6525 to reset to the initial position. Because the sealing strip 6525 has not been fully reset, it is still stuck on the surface of the fixed frame 2, and the sealing plate 651 cannot be reset temporarily. When the sealing strip 6525 is completely released from the stuck position, the sealing plate 651 is reset to the initial position under the action of the elastic telescopic rod 653. At this time, the sealing state between the fixed frame 2 and the window frame 3 is released, and the relative fixed relationship between the two is released synchronously.

[0061] In order to seal the space on the top and bottom sides between the fixed frame 2 and the window frame 3, such as Figure 12 As shown, the sealing device 7 includes a mounting shell 71, which is fixedly installed in the inner cavity of the mounting cavity 32. A sealing plate 72 is slidably installed on one side of the inner cavity of the mounting shell 71. One side of the outer surface of the sealing plate 72 extends to the outside of the mounting shell 71. An oil guide 74 is provided on the other side of the inner cavity of the mounting shell 71. The oil guide 74 is adapted to be used with an oil guide 66. Sealing elements 73 are provided at both ends of the sealing plate 72. Two elastic telescopic rods 76 and two hydraulic telescopic rods 75 are provided on the other side of the outer surface of the sealing plate 72. The inner cavities of the two hydraulic telescopic rods 75 are connected to the inner cavities of the oil guide 74 through hydraulic pipes.

[0062] Furthermore, the structures of the two seals 73 are the same as those of the seal 652, but the inner cavity of the seal 652 in the seal 73 is connected to the inner cavity of the oil guide 74 through a hydraulic pipe.

[0063] Specifically, when the hydraulic oil in the hydraulic component 64 is output, it is sequentially introduced into the inner cavity of the second oil guide component 74, and then diverted by the second oil guide component 74 to the inner cavities of the two hydraulic telescopic rods 75. The two hydraulic telescopic rods 75 synchronously drive the sealing plate 72 and the sealing component 73 to move outward, thereby sealing the gap between the upper and lower sides of the fixed frame 2 and the window frame 3. At the same time, the elastic telescopic rods 76 on both sides undergo tensile deformation.

[0064] Furthermore, since the structure of seal 2 73 is the same as that of seal 1 652, the motion logic of seal 2 73 is the same as that of seal 1 652 when the window is opened, and it is reset to the initial position under the elastic tension of the two elastic telescopic rods 2 76.

[0065] In order to achieve communication between the driven device 6 and the sealing device 7, such as Figure 13 As shown, the oil guide component 66 includes an oil guide tube 661, and a connector 662 is provided on the end face of the oil guide tube 661. The middle part of the outer surface of the connector 662 is fixedly connected to the inner wall of the mounting shell 61.

[0066] Furthermore, such as Figure 14 As shown, the second oil guide component 74 includes a second guide tube 741. A second connector 742 is provided on the end face of the second guide tube 741. The second connector 742 is fixedly installed on the inner wall of the second mounting shell 71. A first connector 662 is provided on the other end of the second guide tube 741. The first connector 662 is adapted to the second connector 742. A magnetic ring for easy connection and a magnetic ring for easy sealing are provided on the surfaces of the second connector 742 and the first connector 662.

[0067] Specifically, when the driven device 6 and the sealing device 7 are installed, the connecting magnetic ring on the connecting part 662 and the connecting magnetic ring on the connecting part 742 are tightly fitted together. At the same time, the sealing magnetic ring on the connecting part 662 is embedded in the sealing groove of the connecting part 742 after being fitted together, and the sealing magnetic ring on the connecting part 742 is synchronously embedded in the sealing groove of the connecting part 662 under the action of magnetic force.

[0068] Furthermore, through the above structural design, the driven device 6 and the sealing device 7 can be quickly docked and sealed, while facilitating maintenance personnel to inspect or replace the driven device 6 or the sealing device 7.

[0069] To seal the space on the other side between the fixed frame 2 and the window frame 3, such as Figure 15As shown, the sealing device 2 8 includes a mounting shell 3 81, which is fixedly installed in the inner cavity of the mounting cavity 32. A sealing plate 3 82 is slidably installed on one side of the inner cavity of the mounting shell 3 81. One side of the outer surface of the sealing plate 3 82 extends to the outside of the mounting shell 3 81. An oil reservoir 85 is provided on the other side of the inner cavity of the mounting shell 3 81. Oil guides 3 87 are provided on both sides of the outer surface of the oil reservoir 85. Two elastic telescopic rods 3 83 and two hydraulic telescopic rods 2 84 are fixedly installed on the inner surface of the inner cavity of the mounting shell 3 81 on the other side of the outer surface of the sealing plate 3 82. The inner cavities of the two hydraulic telescopic rods 2 84 are respectively connected to the inner cavities of the two oil guides 3 87 through hydraulic pipes. A connector 2 742 is provided at the far end of the two oil guides 3 87. Sealing elements 3 86 are provided at both ends of the sealing plate 3 82.

[0070] Furthermore, the connector 742 in the two oil guide components 87 is adapted to be used with the connector 662 on the other end of the guide pipe 741 in the upper and lower sealing devices 7. The two seals 86 have the same structure as the seal 652, but the inner cavity of the hydraulic cylinder 6522 in the two seals 86 is connected to the inner cavity of the two oil guide components 87 through hydraulic pipes.

[0071] Specifically, after the sealing device 28 is installed, it connects with the sealing devices 17 on both sides. The connector 2742 at the port of the two oil guides 387 seals with the connector 1662 at the other end of the guide pipe 2741 in the two sealing devices 17. This allows the hydraulic oil introduced into the inner cavity of the oil guide 274 by the hydraulic component 64 to be synchronously introduced into the inner cavity of the oil guide 387. The oil guide 387 then diverts the oil to the inner cavities of the two hydraulic telescopic rods 284 and the sealing component 386, driving the hydraulic telescopic rods 284 to push the sealing plate 382 to move outward. Since the two sealing components 386 have the same structure as the sealing component 1652, the motion logic of the sealing plate 382 and the sealing component 386 is the same as that of the sealing plate 1651 and the sealing component 1652.

[0072] Furthermore, when the hydraulic oil enters the inner cavity of the hydraulic telescopic rod 84 through the oil guide 3 87, the excess hydraulic oil will flow into the inner cavity of the oil reservoir 85. At the same time, the hydraulic oil in the inner cavity of the oil reservoir 85 can provide dynamic replenishment for the hydraulic oil of the entire hydraulic system.

[0073] Furthermore, through the coordinated action of two sealing elements 386, two sealing elements 73 on the upper and lower sides, and two sealing elements 652, the four corner gaps between the fixed frame 2 and the window frame 3 can be sealed.

[0074] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
