Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and more specifically, to a door and window sealing device. Background Technology

[0002] In the construction industry, the sealing performance of doors and windows, as the connection between buildings and the external environment, has always been a major concern. As people's living standards improve, their requirements for indoor environmental quality are becoming increasingly stringent. They not only expect to maintain a suitable temperature and humidity indoors, but also have an increasing demand for sealing performance such as dustproofing, rainproofing, and sandproofing.

[0003] A search revealed that Chinese Patent CN221032187U discloses an aluminum door and window sealing device. This device addresses the shortcomings of existing technologies, such as the lack of limiting and fixing structures, which results in poor sealing when doors and windows are fixed, reducing the device's practicality. Furthermore, the absence of a buffer structure in existing technologies leads to doors and windows colliding with the frame when closed due to insufficient force, causing damage and economic losses. The new device utilizes the combined action of a stepper motor, segmented threaded rod, slider, sliding sleeve, rubber sheet, sliding rod one, limiting block, sliding rod two, limiting round block, mounting block, electromagnet, telescopic rod one, braking block, and rubber sealing strip one to achieve a sealing and locking effect on aluminum doors and windows, improving both sealing performance and practicality.

[0004] Sealing strips are prone to loosening and shifting under the influence of vibrations from opening and closing doors and windows, as well as wind and sun exposure, causing gaps in the seal. Dust, rain, and sand from the outside can then enter, leading to frequent dust accumulation and dampness in the room. Residents have to increase the frequency of cleaning, which seriously affects their comfort. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a door and window sealing device to solve the problems mentioned in the background art.

[0029] Working principle of this utility model: When the door and window sealing device provided by this utility model needs to be installed, the sealing strip 3 is first fixed to the inner wall of the fixed window frame 2. The slot 4 on one side of the sealing strip 3 is ready to cooperate with the parts on the door and window body 1. Then, the door and window body 1 is brought closer to the fixed window frame 2. At this time, the moving rod 8 slides in the fixed box 6, and the connecting spring 7 is in a compressed state. Because the moving rod 8 and the fixed box 6 are slidably connected, and one end of the moving rod 8 passes through the fixed box 6 and extends to one side;

[0030] As the main body 1 of the door and window is pushed forward, the movable plate 11 contacts the groove 4 of the sealing strip 3. Under the elastic force of the connecting spring 7, the movable plate 11 slides into the groove 4. Since the movable plate 11 and the groove 4 are engaged, the initial sealing and fixing are achieved. At the same time, the movable slide plate 9 slides on the inner wall of the fixing groove 5, the movable column 10 slides in the main body 1 of the door and window, and the movable plate 11 slides in the storage groove 12, ensuring smooth movement of each component. This is because the movable column 10 is slidably connected to the main body 1 of the door and window, and the movable plate 11 is slidably connected to the storage groove 12.

[0031] In the installation of the sealing strip 3, the pin plate 14 is inserted into the fixing slot 13 and the through slot 15 respectively to further stabilize the position of the sealing strip 3 on the fixed window frame 2 and ensure the sealing effect. Finally, the protective cover plate 16 is hinged to the front side of the fixing slot 5 of the door and window body 1. The protective cover plate 16 is put down to protect the internal components of the fixing slot 5.
