AI Technical Summary
In existing electric lift windows, there is a contradiction between the lifting and lowering of the movable sash and the sealing. If the pressure of the sealing strip is too large, it will affect the lifting and lowering of the movable sash; if the pressure is too small, the sealing effect will be poor.
The variable side pressure sealing assembly is adopted, including pulley block, variable block A and variable block B. The pulley block is displaced on the track by the ramp design, which drives the movable fan to move laterally, increases the amount of pressure of the sealing strip, and achieves smooth lifting and sealing.
During the raising and lowering of the movable fan, the slope design of the displacement block achieves side pressure sealing of the sealing strip, improving the sealing performance and ensuring smooth raising and lowering of the movable fan.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building door and window technology, and in particular to an electric lifting window with a movable sash side pressure seal. Background Technology
[0002] Electric lift windows are intelligent window systems that use a motor to drive the movable sash to move up and down. The seal between the movable sash and the frame is achieved through a sealing strip between them. Since the movable sash needs to move up and down within the frame, if the pressure of the sealing strip is designed to be too large, excessive friction will affect the sash's movement; conversely, if the pressure is designed to be too small, the seal will be inadequate. Therefore, the trade-off between smooth sash movement and a tight seal is a problem that urgently needs to be solved in existing technologies. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model discloses an electric lifting window with a movable sash side pressure seal.
[0004] The specific technical solution is as follows:
[0005] An electrically operated lift window with a movable sash and side-pressure sealing includes a movable sash, a fixed sash, and a frame. The frame is composed of an outer frame and an inner frame. The movable sash moves up and down within the frame, and its lifting and sealing are achieved through a displacement side-pressure sealing assembly. The displacement side-pressure sealing assembly includes a pulley group, displacement block A, displacement block B, and a sealing strip. The pulley group is fixed to both sides of the movable sash with screws A and nuts. Displacement block A is fixed to the outer wall of the outer frame with screws B. Displacement block B is fixed to the inner wall of the inner frame with screws B. The sealing strip is installed in a groove in the inner frame that contacts the movable sash, and a small pressure fit is designed between the inner frame and the movable sash. The pulley group includes an inner pulley, an outer pulley, and a bracket. The inner and outer pulleys are mounted on the bracket and can rotate freely around their respective axes. The bracket is fixed to the movable sash with screws A and nuts. The inner pulley is installed higher than the outer pulley, and the inner pulley does not contact displacement block B, and the outer pulley does not contact displacement block A simultaneously.
[0006] The bottom of the displacement block A is a slope A, and the displacement block A has a round hole A and a long hole A, which are respectively inserted into screws B; the top of the displacement block B is a slope B, and the displacement block B has a round hole B and a long hole B, which are respectively inserted into screws B; the displacement block B is higher than the displacement block A.
[0007] The movable and fixed fans are made of aluminum alloy profiles.
[0008] The electric control system of the electric lifting window is located at the top of the window. The motor drives the movable sash to move up and down via a chain. When the movable window is raised to the highest position, the window is closed.
[0009] Compared with the prior art, the present invention has the following beneficial technical effects:
[0010] This utility model solves the contradiction between the lifting and sealing of the movable sash of the electric lifting window, making the movable sash rise and fall smoothly. By fixing the displacement block A on the outer frame and the displacement block B on the inner frame, both displacement blocks A and B are designed with ramps to form a broken track. When the pulley group passes through the track, it will drive the movable sash to move laterally, thereby generating lateral pressure on the sealing strip, increasing the amount of pressure, and improving the sealing performance. Specifically: (1) When the window is closed, the movable sash initially rises from the lowest position. The amount of pressure between the movable sash and the sealing strip is at the minimum, and the friction between the two is the minimum, so that the movable sash can rise smoothly within the frame. Then, when it rises to the highest position to close the window, the movable sash moves to the indoor side by changing the displacement block, pressing the sealing strip to achieve lateral pressure sealing, which improves the sealing performance of the window. (2) When the window is opened, the movable sash moves to the outside side by changing the position of the displacement block. The amount of pressure between the movable sash and the sealing strip is at the minimum value, and the friction between the two is at the minimum, so that the movable sash can descend smoothly within the frame.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the accompanying drawings and specific embodiments.
[0020] like Figure 1-5 As shown: This utility model relates to an electrically operated lifting window with a movable sash side-pressure seal, comprising a movable sash 2, a fixed sash 11, and a frame. The frame is composed of an outer frame 5 and an inner frame 9. The movable sash 2 moves up and down within the frame, and its lifting and sealing are achieved through a displacement side-pressure sealing assembly. The displacement side-pressure sealing assembly includes a pulley group 3, a displacement block A4, a displacement block B8, and a sealing strip 10. The pulley group 3 is fixed to both sides of the movable sash 2 by screws A1 and nuts 7. The displacement block A4 is fixed to the outer wall 501 of the outer frame 5 by screws B6. The displacement block B8 is fixed to the inner frame by screws B6. On the inner wall 901 of 9, a sealing strip 10 is installed in the groove where the inner frame 9 contacts the movable fan 2, and a small pressure amount is designed between it and the movable fan 2; the pulley group 3 includes an inner pulley 301, an outer pulley 302 and a bracket 303; the inner pulley 301 and the outer pulley 302 are installed on the bracket 303 and can rotate freely around their respective axes; the bracket 303 is fixed to the movable fan 2 by screws A1 and nuts 7; the inner pulley 301 is installed higher than the outer pulley 302, and the inner pulley 301 does not contact the displacement block B8 and the outer pulley 302 does not contact the displacement block A4 at the same time.
[0021] The bottom of the displacement block A4 is a slope A401, and the displacement block A4 has a round hole A402 and an elongated hole A403, which are respectively inserted into screws B6; the top of the displacement block B8 is a slope B801, and the displacement block B8 has a round hole B802 and an elongated hole B803, which are respectively inserted into screws B6; the displacement block B8 is higher than the displacement block A4.
[0022] The movable fan 2 and the fixed fan 11 are made of aluminum alloy profiles.
[0023] The electric control system of the electric lifting window is located at the top of the window. The motor drives the movable sash 2 to move up and down via a chain. When the movable window is raised to the highest position, the window is closed.
[0024] When using it, please follow these steps:
[0025] (1) When the movable fan 2 rises from its lowest position, the outer pulley 302 rolls close to the outer wall 501, and the inner pulley 301 rolls close to the displacement block B8. The outer pulley 302 and the inner pulley 301 act as a positioning element, causing the movable fan 2 to rise along the gap between the outer wall 501 and the displacement block B8. At this time, the amount of pressure between the movable fan 2 and the sealing strip 10 is at its minimum, and the friction between them is minimal, allowing the movable fan 2 to rise smoothly within the frame, such as... Figure 6 As shown;
[0026] (2) When the movable fan 2 is about to rise to its highest position, the outer pulley 302 rolls to the bottom of the ramp A401 of the displacement block A4 and gradually rolls upward along the ramp A401, while the inner pulley 301 rolls to the bottom of the ramp B801 of the displacement block B8 and rolls upward along the ramp B801. When the movable fan 2 rises to its highest position and the window is closed, the outer pulley 302 rolls along the ramp A401 onto the displacement block A4, and the inner pulley 301 rolls down the ramp B801 onto the displacement block B8 and contacts the inner wall 901. In this way, under the combined action of the two ramps A401 and B801, the pulley group 3 moves a certain distance towards the interior (see Figure 7 Since the pulley block 3 is fixed together with the movable sash 2, the movable sash 2 also moves a certain distance towards the interior side, thereby pressing the sealing strip 10. At this time, the amount of pressure between the movable sash 2 and the sealing strip 10 is at its maximum, and the sealing effect is the best. That is, the movable sash of the electric lifting window achieves side pressure sealing. Figure 7 As shown;
[0027] (3) When the movable fan 2 descends from the highest position, its displacement process is the opposite of that when it rises. Through the combined action of the two ramps A401 and B801, the pulley block 3 drives the movable fan 2 to move a certain distance to the outside side, so that the amount of pressure between the movable fan 2 and the sealing strip 10 is at the minimum value, and the friction between the two is at the minimum, so that the movable fan 2 can descend smoothly within the frame.
