[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model, and they do not specifically limit the present utility model.

[0026] Referring to Figures 1-3 , the present utility model discloses a heat-insulating casement window, which includes a window frame 1, a window sash and a sealing component. The window sash includes a sash frame 2. An outer sealing position 10 is provided at the outer overlapping part of the window frame 1 and the sash frame 2, and an inner sealing position 20 is provided at the inner overlapping part. Here, the "outer side" refers to the side close to the outside, and the "inner side" refers to the side close to the inside.

[0027] The sealing component includes a first sealing member 5 installed at the top of the window frame 1 and a second sealing member 6 installed at the bottom of the sash frame 2. The first sealing member 5 and the second sealing member 6 are in contact through a sealing contact position; the heights of the outer sealing position 10, the sealing contact position and the inner sealing position 20 decrease in sequence. That is, the outer sealing position 10 is higher than the sealing contact position, and the sealing contact position is higher than the inner sealing position 20.

[0028] On the outer overlapping part of the window frame and the sash frame of the heat-insulating casement window of the present utility model, an outer sealing position is provided, and on the inner overlapping part, an inner sealing position is provided. Inside, a sealing contact position is set through the cooperation of a sealing component, namely a first sealing member and a second sealing member. Therefore, at least three seals are formed between the window frame and the sash frame. Compared with the existing sealing structure, it not only effectively reduces the exchange rate of indoor warm air and outdoor cold air, improves the heat insulation performance and airtightness of the whole window, but also plays a sound insulation role, and has fewer components, a simple structure, low processing difficulty and low cost.

[0029] In addition, the heights of the outer sealing position, the sealing contact position and the inner sealing position decrease in sequence, so that the sealing positions form an inclined sealing design, which is beneficial to closer contact of the sealing positions, thus making the sealing effect better. And to a certain extent, it hinders the flow of indoor warm air to the outside and the flow of outdoor cold air to the inside, thereby further improving the heat insulation performance and airtightness of the whole window.

[0030] Specifically, an outer sealing groove is provided on the outer side of the window frame 1, and an outer sealing strip 3 is provided on the outer sealing groove; an outer sealing surface 21 is provided on the outer side of the sash frame 2; the window frame 1 abuts against the outer sealing surface 21 through the outer sealing strip 3 to form an outer sealing position 10. After closing the window, the outer sealing strip will abut against the outer sealing surface of the sash frame, forming a seal, which can not only block the entry of outdoor air and water into the room, but also block the entry of outdoor foreign objects into the room, and at the same time can also play a sound insulation role.

[0031] An inner sealing surface 11 is provided on the inner side of the window frame 1; an inner sealing groove is provided on the inner side of the sash frame 2, and an inner sealing strip 4 is provided on the inner sealing groove; the sash frame 2 abuts against the inner sealing surface 11 through the inner sealing strip 4 to form an inner sealing position 20. After closing the window, the inner sealing strip will abut against the inner sealing surface of the window frame, forming another seal, further blocking the entry of outdoor air, water and foreign objects into the room, and at the same time further playing a sound insulation role.

[0032] Preferably, both the outer sealing strip 3 and the inner sealing strip 4 are made of rubber.

[0033] Furthermore, the number of the sealing contact positions is at least two, and the height of the sealing contact position close to the outer sealing position 10 is higher than the height of the sealing contact position close to the inner sealing position 20. That is, at least four seals are formed in the present utility model, and the heights of the four seals gradually decrease from the outside to the inside of the room, that is, an inclined sealing design is formed, which is beneficial to making the sealing structure closer, thus making the sealing effect better. Since warm air rises and cold air sinks, this design can reduce the entry of warm air and cold air between the window frame and the sash frame, and to a certain extent hinder the flow of indoor warm air to the outside and the flow of outdoor cold air to the inside, thereby further improving the heat insulation performance and airtightness of the whole window.

[0034] Specifically, as Figures 1-2 shown, a sealing contact part 51 is provided at the top of the first seal 5. The sealing contact part 51 is provided with a contact arm 511 and a contact point. The first seal 5 abuts against the second seal 6 through the contact arm 511 and the contact point respectively; the heights of the outer sealing position 10, the contact arm 511, the contact point and the inner sealing position 20 decrease in sequence. The contact arm and the contact point cooperate with the second seal respectively to form a sealing contact position.

[0035] The contact arm abuts against the first seal. Besides playing a sealing role, it also plays a limiting role. In order to prevent the window frame and the window sash from colliding due to excessive force applied by the user and causing damage, the contact arm is provided at the highest contact position of the first seal and the second seal in the present utility model. When closing the window, the first seal and the second seal come into contact. The contact arm restricts the window sash from moving outdoors through the second seal and plays a certain buffering role. At the same time, compared with the contact point, the contact arm has a larger contact area with the second seal, and can more effectively block the cold air outdoors from entering the room.

[0036] It should be noted that, as Figure 2 shown, the first seal 5 is further provided with a base part 52. The setting of the base part can enhance the strength of the first seal and play a supporting role for the sealing contact part. Wherein, the base part 52 is made of EPDM301 ethylene propylene diene monomer, and the sealing contact part 51 is made of EPDM1602 composite foaming material. The second seal 6 is made of PA66.

[0037] Preferably, the number of the contact points is at least two, and the height of the contact point close to the contact arm 511 is higher than the height of the contact point close to the inner sealing position 20. That is, the present utility model forms at least five seals, and the heights of the sealing positions gradually decrease from outdoors to indoors, that is, an inclined sealing design is formed, which is beneficial to the closer contact of the sealing positions, so as to make the sealing effect better. And to a certain extent, it hinders the warm air indoors from flowing outdoors and the cold air outdoors from flowing indoors, thereby further improving the heat insulation performance and air tightness of the whole window.

[0038] More preferably, as Figures 1-2As shown, the contact points include a first contact point 512, a second contact point 513, a third contact point 514, and a fourth contact point 515, and the first contact point 512, the second contact point 513, the third contact point 514, and the fourth contact point 515 are respectively in contact with the second seal 6; the heights of the outer seal position 10, the contact arm 512, the first contact point 512, the second contact point 513, the third contact point 514, the fourth contact point 515, and the inner seal position 20 decrease in sequence. That is, the utility model forms at least seven seals, and the heights of the seal positions gradually decrease from the outdoor to the indoor, that is, an inclined seal design is formed, which is conducive to closer contact of the seal positions, so that the sealing effect is better. And to a certain extent, it hinders the warm air in the room from flowing to the outside and the cold air outside from flowing into the room, thereby further improving the heat insulation performance and airtightness of the entire window.

[0039] Among them, as Figure 3 shown, a seal contact surface 61 is provided at the bottom of the second seal 6, and the seal contact surface 61 is respectively in contact with the contact arm 511, the first contact point 512, the second contact point 513, the third contact point 514, and the fourth contact point 515. The shape of the seal contact surface is adapted to the contact arm and the contact points, ensuring that after the window is closed, the seal contact surface can be in contact with the contact arm, the first contact point, the second contact point, the third contact point, and the fourth contact point, so as to form five seals on the first seal and the second seal. Combined with the window frame and the sash frame, seven seals of the entire window are formed.

[0040] Furthermore, as Figure 1 shown, the seal assembly further includes a seal contact strip 7, and the seal contact strip 7 is installed in the gap between the second seal 6 and the sash frame 2; the contact points further include a fifth contact point 516, and the fifth contact point 516 is provided between the fourth contact point 515 and the inner seal position 20, and the heights of the fourth contact point 515, the fifth contact point 516, and the inner seal position 20 decrease in sequence; a seal bump 71 is provided at the bottom of the seal contact strip 7, and the seal contact strip 7 is in contact with the fifth contact point 516 through the seal bump 71.

[0041] The setting of the seal contact strip makes the structure of the sash frame more compact, with high strength and better airtightness. The combined setting of the seal contact strip and the fifth contact point enables the entire window to form eight seals. Similarly, its cooperation with other seal positions forms an inclined seal design, which is conducive to closer contact of the seal positions, so that the sealing effect is better. And to a certain extent, it hinders the warm air in the room from flowing to the outside and the cold air outside from flowing into the room, thereby further improving the heat insulation performance and airtightness of the entire window.

[0042] Preferably, the seal contact strip 7 is made of EPDM1602 composite foam.

[0043] Preferably, both the first seal 5 and the second seal 6 are integrally formed, which reduces the number of components, has a simple structure, is conducive to processing, and has a low cost.

[0044] In summary, the present utility model provides a heat-insulating casement window, which effectively reduces the air exchange rate between the inside and outside of the window and has a simple structure.

[0045] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
