[0031] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] The embodiment of the utility model aims to provide a push-pull frame sash sealing structure, by increasing the height of the window sash (the hook-and-turn sash in this embodiment) by a certain dimension, setting a step difference between the vertical frame sash sealing position and the hook-and-turn sealing position, and setting a complete circle of sealing only at the locked position. Therefore, when the window sash is opened, the sealing strip at the middle hook-and-turn position does not contact the remaining positions, thereby greatly reducing the friction generated by the friction of the strip during the push-pull process and improving the push-pull feel.

[0033] Specifically, Figure 1 and Figure 2 As shown, a push-pull frame-sash sealing structure provided by an embodiment of the utility model. The frame-sash sealing structure includes a window frame 1, a window sash 2, a first seal 3 and a second seal 4. The window frame 1 includes at least a frame 11 and a middle frame 12, and the frame 11 and the middle frame 12 are spaced apart from each other to form an installation area 101, and the inner top wall 111 of the frame 11 is lower than the inner top wall 121 of the middle frame 12. The window sash 2 is movably installed in the installation area 101, and a step portion 21 is formed on the top of the window sash 2.

[0034] In this embodiment, as the window sash 2 reciprocates in the installation area, the window sash 2 can be in a closed state (such as Figure 1 ) and the open state (as shown Figure 2 When the window sash 2 is in the closed state, the top of the step portion 21 abuts against the inner top wall 121 of the middle frame 12 through the first seal 3, and the bottom of the step portion 21 abuts against the inner top wall 111 of the frame 11 through the second seal 4. When the window sash 2 is gradually switched from the closed state to the open state, the top of the step portion 21 is first separated from the first seal 3, and then, as the window sash 2 is continuously opened, the bottom of the step portion 21 is gradually separated from the second seal 4.

[0035] Based on the above opening and closing process of the window sash 2, it can be known that when the window sash 2 needs to be closed, the window sash 2 needs to be pushed to the left. Before the bottom of the step portion 21 contacts the second seal 4, the window sash 2 is not subject to any sliding friction resistance; when the bottom of the step portion 21 contacts the second seal 4, the window sash 2 will be subject to friction resistance between the bottom of the step portion 21 and the second seal 4 during the subsequent movement; until the window sash 2 is pushed to the leftmost side, the top of the step portion 21 contacts the first seal 3 to achieve sealing of the window sash 2. In this process, only the bottom of the step portion 21 contacts the second seal 4 to receive a certain friction resistance, and there is no friction resistance at other times, which can improve the push-pull feel of the window sash 2 when it is closed. Furthermore, when the window sash 2 needs to be opened, as long as the window sash 2 moves a short distance to the right, the top of the step portion 21 will be separated from the first sealing member 3. At this time, it is only necessary to overcome the friction resistance between the bottom of the step portion 21 and the second sealing member 4. As the window sash 2 continues to open, when the bottom of the step portion 21 is separated from the second sealing member 4, the window sash 2 is no longer subject to any sliding friction resistance, thereby improving the push-pull feel of the window sash 2 when it is opened.

[0036] In the above embodiment, preferably, the window frame 1 is integrally formed. In other embodiments, the side frame 11 and the middle frame 12 may also be configured as a split structure, which may be adaptively adjusted as required.

[0037] Reference Figure 1 As shown, in this embodiment, when the window sash 2 is in a closed state, the height change region 210 of the step portion 21 is located at one end below the inner top wall 121 of the middle frame 12 and close to the frame 11. Based on this position setting, the contact time between the inner top wall 121 of the middle frame 12 and the top of the step portion 21 can be reduced during the opening and closing process of the window sash 2, thereby reducing the sliding friction force received by the window sash 2 during the opening and closing process.

[0038] In the above embodiment, preferably, the height change area of ​​the step portion 21 is an arc-shaped transition area, so as to avoid jamming during the closing process of the window sash 2, which is beneficial to improving the smoothness of opening and closing of the window sash 2.

[0039] like Figure 3 As shown, in the above embodiment, preferably, a roller 22 is provided at the bottom of the window sash 2 , and the roller 22 is in rolling cooperation with the bottom frame 13 of the window frame 1 to improve the convenience of moving the window sash 2 .

[0040] like Figure 4 As shown, in the above embodiment, preferably, the window sash 2 is provided with an embedded card slot 23, so that a person can insert a hand into the embedded card slot and push and pull the window sash. It can be understood that the embedded card slot 23 is an embedded structure, so it will not affect the overall aesthetics of the window sash 2, and can play a certain decorative role. In addition, the use of the embedded card slot 23 in conjunction with the above-mentioned stepped portion 21 can further improve the convenience of pushing and pulling the window sash 2.

[0041] like Figure 5 As shown, in the above embodiment, preferably, a waterproof baffle 211 is formed on the inner side of the step portion 21, and a drainage groove 212 extending to the outside of the step portion is formed on the step portion 21. It can be understood that based on the setting of the step portion 21, when it rains or there is dew, water will flow from the top of the step portion 21 to the bottom of the step portion 21. At this time, the drainage groove 212 can be used to collect water and drain it to the outside of the window sash 2. In addition, the use of the waterproof baffle 211 can prevent excessive water from overflowing into the window sash 2, further improving the waterproof performance.

[0042] In the above embodiment, preferably, the first seal 3 is detachably mounted on the inner top wall 121 of the middle frame 12 at one end close to the frame 11. The second seal 4 is detachably mounted on the inner top wall 111 of the frame 11 at one end close to the middle frame 12. Thus, the first seal 3 and the second seal 4 can be disassembled, cleaned and replaced to ensure sealing.

[0043] Furthermore, in this embodiment, there is a preset height difference (e.g., 5 cm) between the inner top wall 121 of the middle frame 12 and the inner top wall 111 of the frame 11, and the preset height difference is equal to the height difference between the top and the bottom of the step portion 21. Therefore, when installing the first sealing member 3 and the second sealing member 4, sealing strips of the same size can be selected, and there is no need to select sealing strips of different sizes according to different distance intervals.

[0044] The embodiment of the utility model also provides a sliding door and window, which includes the above-mentioned sliding frame and leaf sealing structure.
