Description

Technical Field

[0001] This invention relates to a lifting and pressing mechanism and a lifting window, belonging to the field of door and window technology. Background Technology

[0002] In existing door and window designs, there are balcony lift windows. This type of window not only has good lighting and widens the view, but also can be raised and lowered to change the indoor ventilation as needed.

[0003] Existing balcony lift windows use a single vertical lifting mechanism for the sliding sash. When closed, the side of the sash contacts the sealing strip on the window frame to achieve a seal. However, this design has several drawbacks: When the sealing strip and the side of the sash are only loosely fitted, the seal is not optimal and may even fail to withstand pressure differences in strong winds, leading to air and water leaks. If the sealing strip and the side of the sash are fitted with an interference fit, while an initial seal is guaranteed, the friction between them is significantly increased, affecting the vertical movement of the lifting mechanism and the lifespan of the motor. Furthermore, the sealing strip wears down considerably over time, resulting in a deterioration in the seal. Replacing the sealing strip increases operating costs. Summary of the Invention

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a lifting and pressing mechanism and a lifting window. Through the cooperation of a changing track positioning path and a lateral movement component, the movable window sash moves as a whole toward the first sealing strip after closing and presses the first sealing strip, thereby achieving a truly effective seal.

[0005] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows: A lifting and pressing mechanism includes a track-changing assembly, a movable window sash, a lateral movement assembly, and a driving lifting assembly; The track-changing assembly includes an upper track and a lower track, and the top of the upper track and the lower track extends with a curved positioning groove. The movable window sash is provided with an upper pulley and a lower pulley on its side, and the upper pulley is slidably installed in the upper track, and the lower pulley is slidably installed in the lower track; The lateral movement component includes a first connecting seat and a second connecting seat. The first connecting seat is fixedly installed on the side of the movable window sash, and the second connecting seat is movably installed on the first connecting seat. The drive lifting assembly includes a lifting drive unit, the output end of which is connected to a lifting drive component, and the lifting drive component is connected to the second connecting seat.

[0006] Furthermore, the first connector is provided with a mounting slot, and a strip-shaped hole is provided through the first connector in the mounting slot. The second connector is movably installed in the strip-shaped hole of the mounting slot by a rivet, and the top of the second connector abuts against the top of the mounting slot, and the bottom of the second connector abuts against the bottom of the mounting slot.

[0007] Furthermore, the lifting drive unit is configured as a drive motor, the lifting drive component is configured as a ball screw, the nut of the ball screw is fixedly connected to a connecting plate, and one side of the second connecting seat is provided with a lug that is hinged to the connecting plate.

[0008] A lift window includes a window frame, a hook, a first sealing strip, and the aforementioned lifting and pressing mechanism. The movable window sash is liftably mounted on the inner side of the window frame via a variable track assembly and is connected to the drive lifting assembly via a lateral movement assembly. The hook is horizontally positioned in the middle of the window frame and is located on the side of the window frame near the positioning groove. The first sealing strip surrounds the square frame formed by the window frame and the hook, and is also located on the side of the window frame near the positioning groove.

[0009] Furthermore, it also includes a second sealing strip, which surrounds the inner side of the window frame and is located on the side of the window frame away from the first sealing strip.

[0010] Furthermore, the second connecting seat is provided with one or more sets of anti-sway pulleys on the side away from the hanging ear, and the rotating end of the anti-sway pulley abuts against the inner side of the window frame.

[0011] Furthermore, the top of the movable window sash is fixed with an upper pressing profile, and the side of the upper pressing profile away from the first sealing strip is provided with an upper pressing slope. The top of the window frame away from the first sealing strip is fixed with a number of upper pressing pulleys that cooperate with the upper pressing slope. The number of upper pressing pulleys are arranged at intervals along the length direction of the upper pressing slope.

[0012] Furthermore, the bottom of the hook is provided with a downward pressing slope on the side near the movable window sash, and the bottom of the movable window sash is provided with a number of sets of downward pressing pulleys that cooperate with the downward pressing slope. The number of sets of downward pressing pulleys are arranged at intervals along the length direction of the downward pressing slope.

[0013] Furthermore, the window frame is configured as a hollow profile structure, and the variable track assembly and the drive lifting assembly are embedded inside the window frame.

[0014] The beneficial effects of this invention are: 1. By coordinating the track-changing positioning path and the lateral movement component, the movable window sash moves as a whole towards the first sealing strip after closing and presses against the first sealing strip, thereby achieving a truly effective seal without friction with the first sealing strip, thus improving the service life of the first sealing strip; 2. By setting anti-sway pulleys, the anti-sway pulleys abut against the inner side of the window frame when the movable window sash is raised, lowered, or moved, preventing the movable window sash from swaying or shaking during raising, lowering, or moving, thus improving structural stability; 3. Through the upper pressing profile and the upper pressing pulley... The interaction between the upper pressing pulley and the upper pressing profile allows the top of the sliding window sash to move towards the first sealing strip when the sliding window sash is closed, thus pressing the sliding window sash and the first sealing strip more tightly and further improving the sealing effect; 4. The interaction between the hook and the lower pressing pulley allows the bottom of the sliding window sash to move towards the first sealing strip when the sliding window sash is closed, thus pressing the sliding window sash and the first sealing strip more tightly and further improving the sealing effect.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the following description is provided in conjunction with the appendix. Figure 1-18 Further analysis of the present invention is required.

[0035] like Figure 1-13 As shown, the present invention provides a lifting and pressing mechanism, including a variable track assembly 10, a movable window sash 20, a lateral movement assembly 30, and a driving lifting assembly 40; The track-changing assembly 10 includes an upper track 101 and a lower track 102, and a curved positioning groove 103 extends from the top of the upper track 101 and the lower track 102. The upper track 101 and the lower track 102 can be configured as an integrated structure or as a separate structure; The movable window sash 20 is provided with an upper pulley 201 and a lower pulley 202 on its side, and the upper pulley 201 is slidably installed in the upper track 101, and the lower pulley 202 is slidably installed in the lower track 102; The lateral movement component 30 includes a first connecting seat 301 and a second connecting seat 302. The first connecting seat 301 is fixedly installed on the side of the movable window sash 20, and the second connecting seat 302 is movably installed on the first connecting seat 301. The drive lifting assembly 40 includes a lifting drive unit, the output end of which is connected to a lifting drive component. The lifting drive component is connected to the second connecting seat 302 to drive the second connecting seat 302 to lift, thereby driving the movable window sash 20 to lift.

[0036] In this embodiment, preferably, the first connecting seat 301 is provided with a mounting slot 3011, and a strip hole 3012 is provided through the first connecting seat 301 in the mounting slot 3011. The second connecting seat 302 is movably installed in the strip hole 3012 of the mounting slot 3011 by a rivet, and the top of the second connecting seat 302 abuts against the top of the mounting slot 3011, and the bottom of the second connecting seat 302 abuts against the bottom of the mounting slot 3011, thereby locking the second connecting seat 302 between the top and bottom of the mounting slot 3011. When the lifting drive assembly 40 drives the second connecting seat 302 to rise and fall, the second connecting seat 302 will not move up and down with the first connecting seat 301, thus improving the stability of the transmission structure of the movable window sash 20 when it rises and falls.

[0037] In this embodiment, preferably, the lifting drive unit is configured as a drive motor 401, the lifting drive component is configured as a ball screw 402, the ball screw 402 is rotatably mounted on the window frame 50 through a bearing seat, the nut of the ball screw 402 is fixedly connected to a connecting plate 403, and one side of the second connecting seat 302 is provided with a hanging lug 3021 that is hinged to the connecting plate 403.

[0038] In addition, the lifting drive component can also be set as a conventional transmission component such as a chain or steel rope, which drives the chain or steel rope to move up or down through the drive motor 401 to drive the movable window sash 20 to rise or fall.

[0039] Specifically, the drive motor 401 drives the ball screw 402 to rotate, causing the nut threaded onto the ball screw 402 and the connecting plate 403 to move up or down, thereby driving the movable window sash 20 to rise and fall on the upper track 101 and the lower track 102. When the movable window sash 20 moves to the highest point, it is in the closed state. At this time, the upper pulleys 201 and lower pulleys 202 on both sides of the movable window sash 20 slide into the positioning grooves 103 at the top of the upper track 101 and the lower track 102, thereby driving the movable window sash 20 as a whole to move towards the first sealing strip 70 and press the first sealing strip 70, achieving a truly effective seal without friction with the first sealing strip 70, thus improving the service life of the first sealing strip 70.

[0040] like Figure 14-18 As shown, the present invention also provides a lift window, including a window frame 50, a hook 60, a first sealing strip 70, and the aforementioned lifting and pressing mechanism. The movable window sash 20 is liftably mounted on the inner side of the window frame 50 via a track-changing assembly 10 and is connected to the drive lifting assembly 40 via a transverse moving assembly 30. The hook 60 is horizontally arranged in the middle of the window frame 50 and is located on the side of the window frame 50 near the positioning groove 103. The first sealing strip 70 surrounds the square frame formed by the window frame 50 and the hook 60 and is also located on the side of the window frame 50 near the positioning groove 103, thus ensuring that the positioning groove 103, the hook 60, and the first sealing strip 70 are all on the same side of the window frame 50.

[0041] In this embodiment, preferably, a second sealing strip 80 is also included. The second sealing strip 80 is arranged around the inner side of the window frame 50, and the second sealing strip 80 is located on the side of the window frame 50 away from the first sealing strip 70. Similar to the sealing structure of a traditional balcony lift window, the second sealing strip 80 is used to fix the conventional seal between the window sash and the window frame 50, which will not be described in detail here.

[0042] In this embodiment, preferably, one or more sets of anti-sway pulleys 303 are rotatably provided on the side of the second connecting seat 302 away from the hanging ear 3021. The rotating end of the anti-sway pulley 303 abuts against the inner side of the window frame 50. When the movable window sash 20 is raised or lowered, the anti-sway pulley 303 is rotatably connected to the profile edge of the inner side of the window frame 50 to prevent the movable window sash 20 from swaying during raising or lowering, thereby improving the structural stability of the movable window sash 20 during raising or lowering. At the same time, when the movable window sash 20 moves, the anti-sway pulley 303 is slidably connected to the profile edge of the inner side of the window frame 50, which can also prevent the movable window sash 20 from swaying during moving, thereby improving the structural stability of the movable window sash 20 during moving.

[0043] In this embodiment, preferably, the top of the movable window sash 20 is fixedly provided with an upper pressing profile 203, and the upper pressing profile 203 is provided with an upper pressing inclined surface 2031 on the side away from the first sealing strip 70. The top of the window frame 50 is fixedly provided with a plurality of upper pressing pulleys 501 that cooperate with the upper pressing inclined surface 2031 on the side away from the first sealing strip 70. The plurality of upper pressing pulleys 501 are arranged at intervals along the length direction of the upper pressing inclined surface 2031.

[0044] Specifically, when the movable window sash 20 rises and closes, it drives the upper pressing profile 203 to move upward, causing the upper pressing inclined surface 2031 to contact the upper pressing pulley 501. Since the upper pressing pulley 501 is fixedly installed on the window frame 50 and cannot move, the relative force generated when the upper pressing pulley 501 and the upper pressing inclined surface 2031 abut against each other can push the top of the movable window sash 20 towards the first sealing strip 70, thereby making the movable window sash 20 and the first sealing strip 70 more tightly pressed together, further improving the sealing effect.

[0045] In this embodiment, preferably, the bottom of the hook 60 is provided with a downward pressing slope 601 on the side near the movable window sash 20, and the bottom of the movable window sash 20 is provided with a plurality of sets of downward pressing pulleys 204 that cooperate with the downward pressing slope 601. The plurality of sets of downward pressing pulleys 204 are arranged at intervals along the length direction of the downward pressing slope 601.

[0046] Specifically, when the movable window sash 20 rises and closes, it drives the lower pressing pulley 204 to move upward, causing the lower pressing pulley 204 to contact the lower pressing slope 601. Since the hook 60 is fixedly installed on the window frame 50, the lower pressing slope 601 cannot move. Therefore, the relative force generated when the lower pressing pulley 204 and the lower pressing slope 601 come into contact can pull the bottom of the movable window sash 20 towards the first sealing strip 70, thereby pressing the movable window sash 20 and the first sealing strip 70 more tightly, further improving the sealing effect.

[0047] In this embodiment, preferably, the window frame 50 is configured as a hollow profile structure, and the variable track assembly 10 and the drive lifting assembly 40 are embedded and installed inside the window frame 50. Similar to the window frame structure of a traditional balcony lift window, the hollow profile structure is used to house the track and lifting assembly inside the window frame to improve the aesthetics of the product, which will not be elaborated here.

[0048] The working principle of this invention is as follows: The drive motor 401 drives the ball screw 402 to rotate, causing the nut threaded on the ball screw 402 and the connecting plate 403 to move up or down, thereby driving the movable window sash 20 to rise and fall on the upper rail 101 and the lower rail 102. When the movable window sash 20 moves to the highest point, it is in the closed state. At this time, the upper pulley 201 and lower pulley 202 on both sides of the movable window sash 20 slide into the positioning groove 103 at the top of the upper rail 101 and the lower rail 102, thereby driving the movable window sash 20 as a whole to move towards the first sealing strip 70 and pressing the first sealing strip 70 to achieve a truly effective seal.

The embodiments used in this document illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the methods and core ideas of this application.
