Description

TECHNICAL FIELD

[0001] The present application relates to the field of door and window connecting components, in particular to a window sealing structure and a casement window. BACKGROUND

[0002] Modern windows are composed of three parts: window frame, transparent part and movable component. The window frame is responsible for supporting the main structure of the window body, which can be made of wood, metal, ceramic or plastic material. The transparent part is attached to the window frame, which can be made of paper, cloth, silk or glass material. The movable component is mainly made of metal material. With the development of building technology and the improvement of human living standards, the structure of windows is becoming more and more complex to meet higher thermal requirements. High-end buildings require double or even triple vacuum glass, double rubber sealing strips and other structures to ensure the best heat preservation and insulation performance.

[0003] Casement windows are the most common type of window, in which the sash is combined with the window frame through hinges, and the sash can be rotated to open. The current casement window mostly uses rubber sealing strips between the sash and the window frame for sealing. When the sash is closed, the sealing strips on the sash and the sealing strips on the window frame are in contact and are pressed to achieve the purpose of sealing. For example, the sealing structure of a full-screen window disclosed in Chinese Patent No. 202222209917.5 forms three seals and two sealing cavities between the rubber strip one and the frame profile, the rubber strip two and the rubber strip three, and the rubber strip three and the frame profile, thereby improving the sealing, sound insulation and heat preservation performance of the window. However, in the above-mentioned scheme, the rubber strip one and the frame profile are in contact, the rubber strip two and the rubber strip three are in contact, and the rubber strip three and the frame profile are in contact, which will cause mutual friction between the rubber strip one and the frame profile, the rubber strip two and the rubber strip three, and the rubber strip three and the frame profile. Over time, this will reduce the sealing performance of the window, as well as the sound insulation and heat preservation performance of the window.

[0004] For another example, the new casement window sash aluminum profile structure disclosed in Chinese Patent No. 202222049844.8 uses the elastic stop of the sealing assembly to fit the vertical edge of the third heat insulation strip of the window sash, uses the elasticity of the elastic stop to make it tightly fit the vertical edge, uses the third sealing gasket to fit the outer window sash plate, and uses the fourth sealing gasket to fit the inner window frame plate, thereby ensuring the sealing performance between the window frame and the window sash. However, the above technical solution also uses the elastic stop to contact the vertical edge, the third sealing gasket to contact the outer window sash plate, and the fourth sealing gasket to contact the inner window frame plate, so it will also cause mutual friction between the elastic stop and the vertical edge, the third sealing gasket and the outer window sash plate, and the fourth sealing gasket and the inner window frame plate, which will reduce the sealing performance of the window and shorten the service life of the window.

The plurality of rotating rods 34 can avoid the above situation, when the window is closed, the rotating rod 34 that is not in contact with the fixed rod 44 will not rotate, and will not affect the rotation of the rotating rod 34 that is first in contact with the fixed rod 44, when the window is opened, the rotating rod 34 that is not separated from the fixed rod 44 will not rotate, and will not affect the rotation of the rotating rod 34 that is first separated from the fixed rod 44, so that the window is opened and closed more smoothly.

The cavities in the drainage sealing strip 5 and the buffer strip 6 also have a heat preservation and sound insulation effect.

[0047] As shown in Figure 1 , Figure 6 and Figure 7As shown, the opposite surfaces of the vertical part of the sash frame 1 and the horizontal part of the fixed window frame 2 are respectively fixedly installed with the sealing and heat insulation band one 12 and the sealing and heat insulation band two 22 along the length direction, the positions of the sealing and heat insulation band one 12 and the sealing and heat insulation band two 22 correspond to each other, the opposite surfaces of the sealing and heat insulation band one 12 and the sealing and heat insulation band two 22 are arc-shaped and are internally provided with cavities. The sealing and heat insulation band one 12 and the sealing and heat insulation band two 22 abut and are tightly squeezed to cooperate with the buckle type sealing assembly to form cavities, and the sealing and heat insulation band one 12 and the sealing and heat insulation band two 22 are internally provided with cavity structures, which can further increase the heat preservation and sound insulation performance of the casement window. Meanwhile, the sealing and heat insulation band one 12 and the sealing and heat insulation band two 22 also have a buffering effect, which can prevent the vertical part of the sash frame 1 and the horizontal part of the fixed window frame 2 from being directly collided and damaged, and can also reduce the noise when closing the window.

[0048] As shown in Figure 1 , Figure 6 and Figure 7 , a plurality of horizontal and vertical reinforcing plates one 11 are arranged in the sash frame 1, and the horizontal reinforcing plates one 11 and the vertical reinforcing plates one 11 are perpendicular to each other.

[0049] As shown in Figure 1 , Figure 6 and Figure 7 , a plurality of horizontal and vertical reinforcing plates two 21 are arranged in the fixed window frame 2, and the horizontal reinforcing plates two 21 and the vertical reinforcing plates two 21 are perpendicular to each other. In this way, the strength of the fixed window frame 2 and the sash frame 1 can be increased, and the service life of the casement window can be prolonged.

[0050] The application is characterized in that when the window is closed, the fixed window frame 2 and the sash frame 1 move along the sash arc, and the sealing fastener 3 and the sealing fastener 4 also move along the sash arc. Because the elastic members on the sealing fastener 3 and the sealing fastener 4 are staggered up and down, the support parts 322 of the two support belts 32 are staggered up and down with the upper and lower parts of the grab parts 422 of the grab belt 42, respectively. Therefore, after the rotating rods 34 on the two support parts 322 and the fixed rods 44 on the upper and lower parts of the grab parts 422 abut, the two fixed rods 44 are pressed towards the middle by the two rotating rods 34, the two support parts 322 are bent downwards and upwards, respectively, and drive the two rotating rods 34 to move downwards and upwards, respectively, the two rotating rods 34 are stretched apart from the two fixed rods 44, and the opening ends of the grab parts 422 are also stretched apart. After the window is closed, the fixed rods 44 are embedded between the two fixed shafts 33, the support parts 322 of the support belts 32 and the grab parts 422 of the grab belt 42 are restored, the two support parts 322 drive the two rotating rods 34 to move upwards and downwards, respectively, and the upper and lower parts of the grab parts 422 drive the two fixed rods 44 to move downwards and upwards, respectively. At this time, the inner sides of the rotating rods 34 and the fixed rods 44 abut, the fixed shafts 33 at the two ends of the rotating rods 34 and the rotating shafts 43 at the two ends of the fixed rods 44 abut, and the sealing heat insulation belt 12 and the sealing heat insulation belt 22 abut and are squeezed tightly. Because the surfaces of the two rotating rods 34 and the fixed rods 44 are made of rubber, the circumferential surfaces of the fixed shafts 33 and the rotating shafts 43 are also made of rubber, the rotating rods 34 are connected with the fixed shafts 33 in rotation, and the rotating shafts 43 are connected with the fixed rods 44 in rotation, therefore, when the window is opened and closed, the rotating rods 34 and the fixed rods 44 abut and rotate, the rotating shafts 43 and the fixed shafts 33 abut and rotate, and after the window is closed, the two rotating rods 34 and the two fixed rods 44 are affected by the elastic force of the two support parts 322 and the upper and lower parts of the grab parts 422, respectively, so that the rotating rods 34 and the fixed rods 44 are pressed against each other, and the sealing property of the window is further improved.
