Description

Technical Field

[0001] This utility model relates to the field of fire-resistant windows, specifically to a fire-resistant window that is resistant to wind pressure. Background Technology

[0002] Fire-resistant windows are windows that, together with their frames, can meet the requirements of fire resistance stability and fire resistance integrity for a certain period of time. Fire-resistant windows mainly consist of a window frame, a window sash, and fire-resistant glass. The fire-resistant glass is fixed in the middle of the window sash, which is connected to the middle of the window frame. The window sash and the window frame are hinged on one side to facilitate opening and closing of the window sash. However, when the window sash is opened to a certain angle to allow air exchange between the inside and outside, if there is wind outside, the wind pressure will cause the window sash to swing left and right. At this time, the window sash will collide with the window frame or the wall, causing the fire-resistant glass to break. In order to avoid this, existing technologies use limiters to limit and support the window frame and the window sash. One type of limiter currently in use is, such as Figure 6 As shown, the system includes a first fixing seat, a second fixing seat, a limiting plate 3, and hook grooves (the hook grooves are L-shaped). During installation, the first fixing seat is installed on the outer wall of the window sash away from the hinge, and a horizontal T-shaped limiting post is fixedly connected to one side of the first fixing seat. The second fixing seat is installed on the outer wall of the window frame away from the hinge (the first fixing seat and the second fixing post can be installed by screws or glue). One end of the limiting plate is movably hinged to the second fixing seat, and hook grooves are spaced apart on one side of the limiting plate. When the fire-resistant window is closed, the limiting plate can be separated from the limiting post on one side of the first fixing seat. At this time, the limiting plate will descend vertically to one side of the window frame due to its own weight, and the window sash can be opened and closed. When the window sash is opened away from the window frame, the limiting plate can be pulled up, and it will move along with the window sash as it opens. At the angle, the corresponding groove on one side of the limiting plate is connected to the limiting post on one side of the first fixing seat. At this time, the window sash and the window frame will be limited and fixed, and cannot be opened or closed by itself. This avoids the window sash from swinging back and forth and hitting the window frame or wall when the window sash is opened due to excessive wind force (refer to the prior art diagram in the figure). However, in order to facilitate the connection between the groove and the limiting post, the groove is usually set to be long and the diameter of the groove needs to be larger than that of the limiting post. When the limiting post is inserted into the groove on one side of the limiting plate, once the wind blows the window sash, the window sash can easily drive the limiting post to move left and right in the groove, causing the limiting post to slide inside the groove. At this time, the limiting post can easily separate from the groove, and the limiting post that slides left and right for a long time will also pull the limiting plate, causing the second fixing post at one end of the limiting plate to loosen, affecting the overall fixing effect.

[0003] Therefore, it is necessary to invent a fire-resistant window that can withstand wind pressure. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-resistant window resistant to wind pressure, comprising a fire-resistant window and a limiter. The limiter includes a first fixed seat, a second fixed seat, a limit plate, a groove, and a limit post. The first fixed seat and the second fixed seat are installed on the outer wall of the fire-resistant window. One end of the second fixed seat is movably hinged to the limit plate. A groove is provided at intervals on one side surface of the limit plate. A limit post is fixedly installed at one end of the first fixed seat. A positioning plate is fixedly installed on the outer wall of the limit plate near the second fixed seat. A protective component is movably connected to one side of the positioning plate.

[0006] Based on the above features: the first fixing seat is installed on the outer wall of the window sash away from the hinge, and the second fixing seat is installed on the outer wall of the window frame away from the hinge. When the window sash is opened away from the window frame, the limiting plate can be pulled up, and as the window sash opens at an angle, the corresponding groove on one side of the limiting plate is connected to the limiting post on one side of the first fixing seat. At this time, the window sash and the window frame will be limited and fixed. When the window sash is blown by the wind, the limiting plate can support and fix it between the window frame and the window sash, while pushing the protective component to move and press against the limiting post. The positioning plate can be limited and fixed at one end of the protective component to prevent the limiting post from shaking or sliding inside the groove, thereby improving the overall fixing effect.

[0007] Preferably, a U-shaped plate is installed at intervals on one side of the limiting plate, and the U-shaped plate has a hollow structure.

[0008] Based on the above features, it facilitates the guiding and translation of protective components.

[0009] Preferably, the positioning plate has a movable groove in the middle, and a fixing nut is fixedly installed in the middle of one side of the positioning plate. The fixing nut is internally threaded with a locking screw, and a handle is fixedly installed at one end of the locking screw.

[0010] Based on the above characteristics: when the locking screw is turned forward by the handle, the locking screw can extend into the positioning plate; when the locking screw is turned backward, the locking screw will move away from the positioning plate; when the locking screw stops rotating, the fixing nut will lock and fix the locking screw.

[0011] Preferably, the protective component includes a protective plate and a connecting block fixedly installed at one end of the protective plate. A guide plate is fixedly installed at the end of the connecting block away from the protective plate, and an arc-shaped groove is formed on one side of the guide plate.

[0012] Based on the above features: when the guide plate is pushed to move, the guide plate can drive the protective plate to move synchronously through the connecting block, so that the protective plate can use the arc groove to clamp and limit the limiting post inside one of the hook grooves.

[0013] Preferably, a movable plate is fixedly installed at one end of the protective plate near the positioning plate, and the movable plate has a first through hole and a second through hole symmetrically opened on its surface.

[0014] Based on the above features: it is convenient to insert the end of the locking screw away from the handle into the first or second through hole to fix the movable plate, thus preventing the entire protective assembly from shifting on its own.

[0015] Preferably, the number of protective plates provided is equal to the number of hooks.

[0016] Based on the above features: when the window is opened at different angles, the limiting post will also be stuck inside the corresponding hook groove. The number of protective plates is equal to the number of hook grooves, so that when the limiting post is stuck inside the hook groove, the limiting post at the corresponding hook groove position can be clamped by the corresponding protective plate.

[0017] Preferably, the side of the hook groove away from the positioning plate is configured as an arc-shaped structure, and the hook groove and the arc-shaped groove are arranged opposite to each other.

[0018] Based on the above features, the hook groove and the arc groove can be used to clamp the limiting post from opposite directions.

[0019] The beneficial effects of this utility model are: By setting up protective components, the overall fixing and support effect is improved. When the window sash is opened to a certain angle, the limiting plate can be pulled to the side of the limiting post, and the limiting post can be locked into the corresponding groove for fixation. This makes it convenient for the limiting plate to be supported and fixed between the window frame and the window sash. Then, the entire protective component is pushed to move. During this process, the guide plate will drive multiple protective plates to move synchronously through the connecting block, so that one of the protective plates can be locked into the outside of the limiting post by the arc groove on one side, preventing the limiting post from shaking or sliding inside the groove and improving the overall fixing effect.

[0020] 2. The protective component can be limited and fixed by the positioning plate, fixing nut and locking screw. When it is not necessary to clamp the limiting post, the entire protective component can be pushed towards the second fixed seat, so that one end of the locking screw is inserted into the first through hole to fix the movable plate and prevent the protective component from shifting. When it is necessary to pull the protective component to extend, the locking screw can be reversed to disengage from the first through hole. At this time, the protective component can be pulled out. When the arc groove is pressed against one side of the limiting post, the second through hole on the surface of the movable plate will be aligned with the locking screw. Then the locking screw can be rotated forward again to insert into the second through hole to fix it and prevent the protective component from shifting on its own and affecting the clamping effect.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] See attached document Figures 1-5 The present invention provides a fire-resistant window that is resistant to wind pressure, including a fire-resistant window and a limiter. The fire-resistant window includes a window frame, a window sash and fireproof glass. The fireproof glass is fixed in the middle of the window sash, the window sash is connected in the middle of the window frame, and the window sash and one side of the window frame are hinged to facilitate the opening and closing of the window sash. The limiter includes a first fixing seat 1, a second fixing seat 2, a limiting plate 3, and hook grooves 4. During installation, the first fixing seat 1 is installed on the outer wall of the window sash away from the hinge, and a horizontal T-shaped limiting post 7 is fixedly connected to one side of the first fixing seat 1. The second fixing seat 2 is installed on the outer wall of the window frame away from the hinge (the first fixing seat 1 and the second fixing post 2 can be fixed with screws or glued). One end of the limiting plate 3 is movably hinged to the second fixing seat 2, and hook grooves 4 are spaced apart on one side surface of the limiting plate 3. The spacing between adjacent hook grooves 4 is equal. When the fire window is closed, the limiting plate 3 can be separated from the limiting post 7 on one side of the first fixed seat 1. At this time, the limiting plate 3 will descend vertically to one side of the window frame due to its own weight, while the window sash can be opened and closed. When the window sash is opened away from the window frame, the limiting plate 3 can be pulled up, and as the window sash opens, the corresponding hook groove 4 on one side of the limiting plate 3 is connected to the limiting post 7 on one side of the first fixed seat 1. At this time, the window sash and the window frame will be limited and fixed, and cannot be opened and closed by itself, so as to avoid the window sash swinging back and forth and hitting the window frame when the window sash is opened due to excessive wind force. A protective component 6 is provided on one side of the limiting plate 3. The protective component 6 includes multiple protective plates 61 and a connecting block 62 fixedly installed at one end of the protective plates 61 (the number of protective plates 61 is equal to the number of hook grooves 4). A guide plate 63 is fixedly installed at the end of the connecting block 62 away from the protective plate 61. The protective plates 61 are spaced apart, and the distance between adjacent protective plates 61 is equal. An arc-shaped groove 64 is opened on one side of the protective plate 61. The side of the hook groove 4 away from the positioning plate 5 is set as an arc structure. The hook groove 4 and the arc-shaped groove (64) are arranged opposite to each other. Before the limiting plate 3 is pulled to move, the entire protective component 6 can be pulled towards the second fixed seat 2 first, so that the protective plate 61 is moved between two adjacent hook grooves 4. To prevent the protective plate 61 from obstructing the hook groove 4, the limiting plate 3 is then pulled to one side of the limiting post 7, so that the limiting post 7 is inserted into the corresponding hook groove 4. Then, the entire protective assembly 6 can be pushed to move towards the first fixed seat 1. During this process, the guide plate 63 will drive multiple protective plates 61 to move synchronously through the connecting block 62, so that one of the protective plates 61 is inserted into the outside of the limiting post 7 by the arc groove 64 on one side. At this time, the limiting post 7 will be limited and clamped by the hook groove 4 and the arc groove 64 on both sides and cannot shake. When the window sash is blown by the wind, the limiting plate 3 can support and fix it between the window frame and the window sash. At the same time, the setting of the protective plate 61 prevents the limiting post 7 from shaking or sliding inside the hook groove 4, thus improving the overall fixing effect.

[0025] See attached document Figures 1-5Multiple U-shaped plates 31 (with a hollow structure in the middle) are spaced apart on one side surface of the limiting plate 3. The guide plate 63 moves through the middle of the U-shaped plates 31, which facilitates the guide plate 63 to drive multiple protective plates 61 to move synchronously through the connecting block 62. A positioning plate 5 is fixedly installed on one side surface of the limiting plate 3. The positioning plate 5 has a movable groove 51 in the middle, making the positioning plate 5 have a U-shaped structure. A movable plate 611 is fixedly installed on the side of the protective plate 61 away from the limiting post 7. The movable plate 611 is inserted into the movable groove 51. The surface of the movable plate 611 has a first through hole 612 and a second through hole 613 symmetrically opened. A fixing nut 52 is fixedly installed on the side of the positioning plate 5 away from the limiting plate 3 (the surface of the limiting plate 3 has a hole, the position of which is aligned with the hole in the middle of the fixing nut 52. The hole in the middle of the fixing nut 52 has an internal thread). A locking screw 53 is threadedly connected to the middle of the fixing nut 52. A handle 54 is fixedly installed on the end of the locking screw 53 away from the positioning plate 5. When the locking screw 53 is rotated clockwise via handle 54, the locking screw 53 can extend into the positioning plate 5. When the locking screw 53 is rotated counterclockwise, it will move away from the positioning plate 5. When the locking screw 53 stops rotating, the fixing nut 52 will lock the locking screw 53 in place. When it is not necessary to clamp the limiting post 7, the entire protective assembly 6 can be pushed towards the second fixing seat 2, so that the movable plate 611 is inserted into the inside of the positioning plate 5. At this time, the first through hole 612 will be aligned with the locking screw 53. Then, the locking screw 53 can be rotated clockwise to extend into the positioning plate 5, making it easier to lock the screw 53. 3. Insert the end away from the handle 54 into the inside of the first through hole 612 to prevent the protective component 6 from shifting. When it is necessary to pull the protective component 6 to extend, the locking screw 53 can be reversed to disengage from the first through hole 612. At this time, the protective component 6 can be pulled to move, so that the movable plate 611 gradually extends out of the movable groove 51. When the arc groove 64 is pressed against one side of the limiting post 7, the second through hole 613 on the surface of the movable plate 611 will be aligned with the locking screw 53. Then the locking screw 53 can be rotated forward again to extend into the positioning plate 5, so that the end of the locking screw 53 away from the handle 54 can be inserted into the inside of the second through hole 613 for fixing.

[0026] The usage process of this utility model is as follows: Before the limiting plate 3 is connected to the limiting post 7, the entire protective assembly 6 can be pulled towards the second fixed seat 2, causing the protective plate 61 to shift between two adjacent hook grooves 4, and the movable plate 611 will be inserted into the inner side of the positioning plate 5. At this time, the first through hole 612 will be aligned with the locking screw 53. Then, the locking screw 53 can be rotated forward and inserted into the first through hole 612 for fixation. When the window sash is opened to a certain angle, the limiting plate 3 can be pulled to one side of the limiting post 7, and the limiting post 7 will be inserted into the corresponding hook groove 4. The locking screw 53 can be reversed to disengage from the first through hole 612, and then the entire protective assembly 6 can be moved. During this process, the guide plate 63 will drive multiple protective plates 61 to move synchronously through the connecting block 62, so that one of the protective plates 61 is fixed outside the limiting post 7 by using the arc groove 64 on one side. At this time, the second through hole 613 on the surface of the movable plate 611 will be aligned with the locking screw 53. Then the locking screw 53 can be rotated forward again to insert into the second through hole 613 for fixation. When the open window sash is blown by the wind, the limiting plate 3 can support and fix it between the window frame and the window sash.
