Description

Technical Field

[0001] The utility model relates to the technical field of window sash lifters, in particular to a window sash lifter. Background Art

[0002] With the widespread use of aluminum alloy doors and windows in buildings, various large-scale functional buildings have emerged. To meet the indoor ventilation requirements of large-scale buildings and comply with national regulations, the width of casement windows has become increasingly wider. As the window sash becomes wider, the hinge or sliding support is located on the same side of the window sash. Under the long-term weight of the window sash and glass, the other side of the hinge or sliding support will sag to varying degrees. When the window sash is closed and opened, the friction between the window frame and the window sash increases due to the sag, and the opening and closing force of the opening sash greatly exceeds the national standard. In the existing technology, when lifting the window sash, the operation is not simple and quick, making the lifting procedure relatively inconvenient and the lifting is unchanged.

[0003] For example, patent application number CN202321642518.6 provides a door and window sash lifter, which belongs to the field of medical device technology. The lifter is equipped with a movable plate and a threaded rod, which can adjust the clamping range of the fixing buckle according to the thickness of different window frames, better fix the window frame firmly, and has high safety. When in use, when lifting the window sash, because the operation is not simple and quick, the lifting procedure is relatively inconvenient and the lifting is not fixed.

[0004] For example, patent application number CN201320152099.8, the utility model relates to an aluminum alloy casement window sash lifting assist device, which is used to lift the aluminum alloy outward-opening window sash when the window sash is closed. The window sash lifting assist device includes a window sash and a window frame that matches it, and is characterized in that a pulley is installed at the bottom of the window sash, and a slide gasket is fixed on the inner side surface of the lower part of the window frame at a position corresponding to the pulley. This product has the function of reducing the resistance when the window sash is opened and closed, solving the problem of sagging of large casement window sashes, and extending the service life of the product. During use, when lifting the window sash, the lifting procedure is relatively inconvenient because the operation is not simple and quick, and the lifting problem remains unchanged. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a window sash lifter, which solves the problem that when lifting the window sash, the lifting procedure is inconvenient and the lifting remains unchanged due to the lack of simple and quick operation.

Since the connecting rod passes through one end of the rotating plate and contacts with the rotating plate, the rotation of the rotating plate can be ensured without hindering the rotation of the rotating plate. When the rotating plate rotates, the angle of the rotating plate can be changed, and the rotating plate can be horizontally located under the fixing plate and can be stacked on the bottom of the fixing plate. In this way, the window sash can be closed, achieving a lifting effect, and the eccentric locking point is movably connected to the window frame, and the eccentric locking point can be rotated to adjust the lifting height.

[0008] Preferably, the cross-sectional shape of the limiting plate is circular, and the eccentric locking point is movably connected to the window frame.

[0010] Preferably, a connecting rod is provided on the top of the limiting plate, and the connecting rod is located between the limiting plate and the window sash.

[0011] Preferably, the limiting plate is fixedly connected to the window sash via a connecting rod, and the connecting rod passes through one end of the rotating plate and contacts the rotating plate.

[0012] Preferably, the length of the fixing plate is greater than the length of the window frame, and the window frame is located on one side of the window sash. The fixing plate is fixedly connected to the window sash by screws, so that the fixing plate can be stably located under the window sash, thereby improving stability. The limiting plate is located under the rotating plate and is in contact with the rotating plate, which will not affect the rotation of the rotating plate. The limiting plate is fixedly connected to the connecting rod to prevent the limiting plate from falling downward, making it convenient to block the rotating plate and improving the stability of the rotating plate. Beneficial effects

[0013] The utility model provides a window sash lifter. Compared with the prior art, it has the following beneficial effects:

[0014] 1.

When the rotating plate rotates, the angle of the rotating plate can be changed, and the rotating plate can be horizontally located below the fixed plate and can be stacked on the bottom of the fixed plate. In this way, the window sash can be closed and the lifting effect is achieved. The eccentric locking point is movably connected to the window frame, and the eccentric locking point can be rotated to adjust the lifting height.

[0015] 2. The window sash lifter is fixedly connected to the window sash through a fixing plate by screws, so that the fixing plate can be stably located under the window sash, thereby improving stability. The limiting plate is located under the rotating plate and is in contact with the rotating plate, which will not affect the rotation of the rotating plate. The limiting plate is fixedly connected to the connecting rod to prevent the limiting plate from falling downward, making it convenient to block the rotating plate and improving the stability of the rotating plate.
