[0002] In modern architecture, doors and windows are not only crucial components for ventilation and lighting, but also an indispensable part of building energy conservation systems. Their performance directly affects the overall comfort and energy efficiency of the building. The sealing performance of doors and windows is vital for indoor insulation, windproofing, waterproofing, and soundproofing. High-quality sealing designs effectively block indoor and outdoor air circulation, reducing heat loss and significantly lowering energy consumption for winter heating and summer cooling, achieving energy conservation and environmental protection goals. Simultaneously, good sealing prevents rainwater infiltration and wind and sand intrusion, protecting the indoor environment from the impact of external climate changes, which is especially important during extreme weather conditions. Furthermore, doors and windows with excellent sealing performance can effectively isolate noise, providing residents with a quiet and comfortable living and working environment, particularly important in busy urban areas.

[0003] In existing technologies, most automatic window closing devices connect and secure windows to the window frame using bolts. When maintenance, replacement, or adjustment of the automatic closing device is required, these bolts typically need to be removed. This operation is not only time-consuming and labor-intensive but also demands a certain level of technical skill from the user. In some cases, specific professional tools, such as wrenches, drills, or bolt pullers, are needed to successfully complete the disassembly and assembly. For ordinary users, this process may be overly complex, increasing maintenance costs and increasing the risk of further damage to the window or the device itself due to improper operation.

[0004] To address this issue, an automatic telescopic closing mechanism for doors and windows with sealing function is proposed. Utility Model Content

[0035] The waterproof sealing assembly includes multiple hollow strips 5, which are fixedly connected to the outside of the window body 6. Multiple springs 20 are installed on the inner wall of each hollow strip 5. A sealing gasket 8 is slidably connected inside each hollow strip 5. A sealing groove 4 is opened on the outside of the window frame 1. One side of the sealing gasket 8 abuts against the inside of the sealing groove 4. A retaining ball 10 is engaged inside a retaining groove 9. One end of each spring 20 is fixedly connected to one side of the sealing gasket 8, and the other end is fixedly connected to the inner wall of the hollow strip 5. A suspension plate 7 is fixedly connected to the outside of the window frame 1, and a support rod 2 is fixedly connected between the suspension plate 7 and the window frame 1. The window frame 1, as the main structure of the door and window, is used to fix and support the entire door and window assembly, providing a stable foundation for the installation and operation of the window. The window body 6 achieves the opening and closing function of the door and window through a rotating connection on one side of the window frame 1. Simultaneously, the waterproof sealing assembly on the outer periphery enhances the sealing performance of the door and window. The slot 9 is used so that when the window body 6 is closed, the sealing gasket 8 around it is tightly pressed against the inside of the slot 9 by the action of the spring 20. The hollow strip 5 is used to support the various components inside. The electric push rod 3 is used to automatically open and close the window body 6. The ball joint 10 is used to connect the electric push rod 3, so that its output end is fixed on the window body 6, and the window body 6 is opened and closed when activated. The suspension plate 7 is used to prevent rainwater from hitting the window body 6 or causing water to accumulate around the window body 6. The support rod 2 is used to support the suspension plate 7 to ensure its stability.

[0036] Reference Figure 1 - Figure 5The fixing assembly includes a first connecting half-ring 11 and a second connecting half-ring 13. Both the first connecting half-ring 11 and the second connecting half-ring 13 are rotatably connected to the end of the electric push rod 3 away from the retaining ball 10. A plug block 14 is fixedly connected to the outer side of the first connecting half-ring 11, and a fixing block 19 is fixedly connected to the outer side of the second connecting half-ring 13. A locking component is provided inside the fixing block 19. The first connecting half-ring 11 and the second connecting half-ring 13 are used to fix the electric push rod 3 to the fixing shaft 12, allowing the electric push rod 3 to rotate on the fixing shaft 12 during operation. The plug block 14 cooperates with the fixing block 19 to close the first connecting half-ring 11 and the second connecting half-ring 13, ensuring stability on the fixing shaft 12.

[0037] Reference Figure 1 - Figure 5 The locking assembly includes a housing 15, with a pin 16 slidably connected inside the housing 15. A spring 17 is sleeved on the outside of the pin 16, and a pad 18 is fixedly connected to the outside of the pin 16. A plug block 14 is inserted into a fixed block 19, and the pin 16 is inserted into the plug block 14. A fixed shaft 12 is positioned between a connecting half-ring 11 and a connecting half-ring 13. One end of the spring 17 is fixedly connected to one side of the pad 18, and the other end of the spring 17 abuts against the inner wall of the housing 15. The housing 15 serves to support the various components inside. The pin 16 is used to insert into the plug block 14, so that the plug block 14 and the fixed block 19 are tightly fixed, ensuring the stability of the electric push rod 3 during operation. The spring 17 ensures that the pin 16 is tightly inserted into the plug block 14 without external force. The pad 18 supports the spring 17 and also prevents the pin 16 from being pulled out of the housing 15.

[0038] Working Principle: During the opening and closing of doors and windows, the electric push rod 3 is the main driving force source. When the door or window needs to be closed, the electric push rod 3 receives a control signal, and its output end drives the retaining ball 10 to pull the window body 6 towards the window frame 1. The retaining ball 10 engages inside the retaining groove 9 of the window body 6, transmitting the pulling force to the window body 6 through a stable connection, thereby achieving smooth closure. During the closing process, the waterproof sealing component on the outer periphery of the window body 6 begins to function. The sealing function of the waterproof sealing component is achieved through the cooperation of the hollow strip 5, the sealing gasket 8, and the second spring 20. When the window body 6 is closed, the sealing gasket 8 installed inside the hollow strip 5 is pressed into the sealing groove 4 on the outer side of the window frame 1 under the action of the second spring 20, forming a highly efficient sealing barrier. The elastic force provided by the second spring 20 ensures that the sealing gasket 8 fits tightly against the sealing groove 4, effectively preventing the infiltration of water, air, and dust, thereby significantly improving the sealing performance of the door and window. The electric push rod 3 is securely mounted on the fixed shaft 12 by a fixing assembly, which includes a connecting half-ring 11 and a connecting half-ring 2 13. These two are rotatably connected around the fixed shaft 12, ensuring that the electric push rod 3 can rotate freely on the fixed shaft 12. The closure of the connecting half-ring 11 and the connecting half-ring 2 13 is achieved by the cooperation between the insert block 14 and the fixing block 19. The insert block 14 is inserted into the fixing block 19 and further secured by the pin 16 in the locking assembly. The pin 16 is pressed into the insert block 14 by the action of the spring 17, ensuring the stability and closure of the connecting half-rings, thereby fixing the electric push rod 3 on the fixed shaft 12 and ensuring its stability during operation. When it is necessary to open the door or window, the electric push rod 3 operates, and the locking ball 10 pushes the window body 6 outward through the locking groove 9.
