Description

Technical Field

[0001] This utility model relates to the field of inward-opening system windows, specifically an inward-opening system window with a buffer structure. Background Technology

[0002] Inward-opening system windows are integrated window systems formed by the organic combination of various components such as profiles, hardware, glass, and seals through standardized design and industrialized production. They open by rotating inward. These system windows have good airtightness, watertightness, thermal insulation, and wind pressure resistance, and can adapt to different building environments and usage needs. They have been widely used in modern buildings, providing users with comfortable and safe living and working spaces.

[0003] In practical use, to ensure safety of living or use, especially in high-rise buildings, existing inward-opening window systems are usually equipped with limiters. A limiter is a hardware accessory that connects the window frame and the window sash. Its main function is to limit the opening angle of the window. By setting a certain maximum opening range, it prevents people from accidentally falling out of the window due to excessive opening, thereby effectively reducing the risk of safety accidents and providing basic protection for the personal safety of people indoors.

[0004] However, while existing limiters can effectively limit the opening angle of window sashes and ensure safety to a certain extent, some problems still exist in practical applications. When the outside wind is too strong, the powerful airflow will push the window sash, causing it to close rapidly under the action of the wind. During this rapid closing process, there will be a violent impact between the window sash and the window frame. This impact will not only damage the profiles, glass and other components of the system window, but also exert a large impact force on the limiter itself, which can easily lead to deformation and damage of the limiter. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an inward-opening system window with a buffer structure to solve the technical problem that strong external airflow can cause the window sash to close and hit the window frame, resulting in damage to the internal structure of the system window.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inward-opening system window with a buffer structure, comprising a frame, a window body connected inside the frame, a groove formed in the inner wall of the frame, a buffer assembly installed at the bottom of the window body, the buffer assembly including a damper and a hydraulic rod, a cavity formed inside the damper, hydraulic oil being disposed inside the cavity, a piston installed at the end of the hydraulic rod, and multiple sets of throttling orifices being disposed inside the piston.

[0007] By adopting the above technical solution, the problem of strong external airflow causing the window sash to close and hit the window frame, resulting in damage to the internal structure of the system window, is solved. When the external airflow pushes the window to close, the window body pushes the damper back into the groove through the fixed seat at the bottom. During the process of the hydraulic rod retracting into the damper, the hydraulic oil inside the damper blocks the movement of the piston, thereby slowing down the closing speed of the window.

[0008] The present invention is further configured such that the ends of the damper and the hydraulic rod are provided with connecting rings, and the interiors of the two sets of connecting rings are respectively provided with a fixed seat and an adjusting rod.

[0009] Preferably, the damper is movably connected to the fixed seat through a connecting ring at its end, thereby fixing the damper at the bottom of the window. The hydraulic rod is movably connected to the adjusting rod through a connecting ring at its end, so that one end of the hydraulic rod is installed in the groove of the frame.

[0010] The present invention is further configured such that a sliding groove is provided at the top of the groove, and a first fixing block and a second fixing block are sleeved on the outer wall of the adjusting rod, with the second fixing block located in the sliding groove.

[0011] Preferably, when it is necessary to change the opening angle of the window, the first fixing block at the end of the adjusting rod is pushed and moved in the slide groove.

[0012] The present invention is further configured such that the diameters of the first fixing block and the second fixing block are greater than the diameter of the end of the slide groove.

[0013] Preferably, the first fixing block and the second fixing block fix the adjusting rod inside the slide groove to prevent the adjusting rod from coming off the slide groove.

[0014] The present invention is further configured such that a locking pin is movably installed inside the adjusting rod, and locking grooves are provided on both sides of the bottom end of the inner wall of the slide groove.

[0015] Preferably, when the maximum opening angle of the window is fixed, the adjusting rod is engaged in the slot through the locking post, so that the adjusting rod cannot be moved.

[0016] The present invention is further configured such that the locking post passes through the adjusting rod, and the length of the locking post is greater than the length of the adjusting rod.

[0017] Preferably, when it is necessary to move the adjusting rod, the locking pin is first raised upwards so that the locking pin is disengaged from the control of the locking slot.

[0018] The present invention is further provided that a lifting plate is installed on the top of the locking post.

[0019] Preferably, personnel can lift the locking post upwards using a lifting plate.

[0020] The present invention is further configured such that the diameter of the second fixing block is equal to the inner wall diameter of the groove, and the second fixing block is circular.

[0021] Preferably, the diameter of the second fixing block is equal to the diameter of the slide groove, so that when the adjusting rod is fixed at the position of the locking post, it is not easy to tilt to the outside of the frame.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention solves the problem of strong external airflow causing the window sash to impact the window frame when closing, resulting in damage to the internal structure of the system window, by setting up a frame, window body, damper, hydraulic rod, piston, and throttling orifice. When the external airflow pushes the window body to close, the window body pushes the damper back into the groove through the fixed seat at the bottom. During the process of the hydraulic rod retracting into the damper, the hydraulic oil inside the damper blocks the movement of the piston, thereby slowing down the closing speed of the window body.

[0024] This utility model, by setting up a lifting plate, adjusting rod, first fixing block, second fixing block, locking post, and locking groove, allows the window opening angle to be changed when it is necessary to raise the lifting plate upwards, so that the locking post connected to the bottom of the lifting plate moves into the second fixing block. Then, the adjusting rod is pushed to one side of the slide groove. When the adjusting rod moves to the end of the slide groove, the lifting plate is pushed downwards, so that the locking post is engaged in the locking groove on one side of the slide groove, thereby changing the opening angle of the window.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figure 1 — Figure 6 The system includes a frame 1, with a window 2 connected inside the frame 1. The inner wall of the frame 1 has a groove 101. A buffer assembly is installed at the bottom of the window 2. The buffer assembly includes a damper 3 and a hydraulic rod 304. The damper 3 has a cavity 303 inside, which is filled with hydraulic oil. A piston 305 is installed at the end of the hydraulic rod 304. The piston 305 has multiple sets of throttling holes 306 inside. This solves the problem that strong external airflow will cause the window sash to close and hit the window frame, causing damage to the internal structure of the system window. When the external airflow pushes the window 2 to close, the window 2 pushes the damper 3 back into the groove 101 through the fixed seat at the bottom. During the process of the hydraulic rod 304 retracting into the damper 3, the hydraulic oil inside the damper 3 blocks the movement of the piston 305, thereby slowing down the closing speed of the window 3.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 Both the damper 3 and the hydraulic rod 304 have connecting rings 301 at their ends. The two sets of connecting rings 301 are respectively provided with a fixed seat 302 and an adjusting rod 4. The damper 3 is movably connected to the fixed seat 302 through the connecting rings 301 at its ends, so that the damper 3 is fixedly installed at the bottom of the window 2. The hydraulic rod 304 is movably connected to the adjusting rod 4 through the connecting rings 301 at its ends, so that one end of the hydraulic rod 304 is installed on the groove 101 of the frame 1.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4The top of the groove 101 is provided with a slide groove 102. The outer wall of the adjusting rod 4 is fitted with a first fixing block 401 and a second fixing block 402, and the second fixing block 402 is located in the slide groove 102. When it is necessary to change the opening angle of the window 2, the first fixing block 402 at the end of the adjusting rod 4 is pushed and moved in the slide groove 102.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 6 The diameters of the first fixing block 401 and the second fixing block 402 are larger than the diameter of the end of the slide groove 102. The first fixing block 401 and the second fixing block 402 fix the adjusting rod 4 inside the slide groove 102 to prevent the adjusting rod 4 from coming off the slide groove 102.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The adjusting rod 4 has a locking post 403 installed inside. The sliding groove 102 has slots 103 on both sides of the bottom end of the inner wall. When the maximum opening angle of the window 2 is fixed, the adjusting rod 4 is locked into the slot 103 through the locking post 403, so that the adjusting rod 4 cannot move.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The locking post 403 passes through the adjusting rod 4. The length of the locking post 403 is greater than the length of the adjusting rod 4. When it is necessary to move the adjusting rod 4, the locking post 403 is first lifted upward so that the locking post 403 is disengaged from the control of the locking groove 103.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 A lifting plate 404 is installed on the top of the locking post 403, which allows personnel to lift the locking post 403 upwards.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The diameter of the second fixing block 402 is equal to the inner wall diameter of the slide groove 102, and the second fixing block 402 is set to be circular. The diameter of the second fixing block 402 is equal to the diameter of the slide groove 102, so that when the adjusting rod 4 is fixed by the position of the locking post 403, it is not easy to tilt to the outside of the frame 1.

[0045] Second embodiment:

[0046] Please see Figure 7 A dustproof plate 5 is movably installed on the outer wall of the first fixing block 401, and the surface area of ​​the dustproof plate 5 is larger than the exposed area of ​​the top of the slide 102. The dustproof plate 5 covers the top of the slide 102 to prevent dust from falling into the slide 102 and hindering the sliding of the second fixing block 402 in the slide 102.

[0047] In practical operation, when the window 2 is closed, the damper 3 and hydraulic rod 304 retract into the groove 101 inside the window 2. When the window 2 is opened, the window 2, through the fixed base 302 fixed at the bottom, causes the damper 3 to rotate around the connection between the window 2 and the frame 1. The hydraulic rod 304 is fixedly mounted on the groove 101 inside the frame 1 through the adjusting rod 4, causing the damper 3 and the hydraulic rod 304 to move away from each other. During the process of moving away from each other, the piston 305 at the end of the hydraulic rod 304 pushes the hydraulic oil in the cavity 303 inside the damper 3. The hydraulic oil resists the piston, thereby causing the damper 3 to rotate away from the frame 1. The damper 3 and the hydraulic rod 304 work together to apply a certain resistance to the opening of the window 2. In addition, the piston 305 is provided with multiple sets of throttling holes 306. When the piston 305 squeezes and pushes the hydraulic oil in the cavity 303, the hydraulic oil flows into the other side of the piston 306 through the throttling holes 306. Thus, the buffer assembly composed of the damper 3 and the hydraulic rod 304 can achieve a large resistance of hydraulic oil to piston 305 when the window 2 is closed quickly, and a small resistance of hydraulic oil to piston 305 when the window 2 is closed slowly. Thus, when the window 2 is pushed by a large external wind force, the buffer assembly can buffer the closing action of the window 2.

[0048] When it is necessary to change the opening angle of window 2, first lift the lifting plate 404 upward, so that the locking post 403 connected to the bottom of the lifting plate 404 moves into the second fixing block 402. Then push the adjusting rod 4 to one side of the slide groove 102. When the adjusting rod 4 moves to the end of the slide groove 102, push the lifting plate 404 downward, so that the locking post 403 is engaged in the locking groove 103 on one side of the slide groove 102, thereby changing the opening angle of window 2.
