Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to a door and window structure. Background Art

[0002] Lifting windows are a type of window with a specific structure and function. The characteristic is that the window sash can slide up and down on the track. Usually half of the window sash is fixed and cannot slide, while the other half of the window sash can slide on the track. The design of this window not only provides flexible ventilation and lighting solutions, but also has some significant advantages due to its unique opening method. Compared with traditional windows and doors, lifting windows have higher security and anti-theft performance. In addition, lifting windows also have better sound insulation and heat preservation effects, providing residents with a quieter and more comfortable living environment.

[0003] However, when the existing lifting window is raised or lowered, the movable leaf is generally driven by a driving motor to drive a sprocket chain or a gear rack or a synchronous belt synchronous wheel to drive the movable leaf up and down. Since the sprocket chain or the gear rack or the synchronous belt synchronous wheel are mostly mechanical friction, they are prone to serious wear after long-term use, which can easily shorten the service life of the lifting window. In addition, the sprocket chain or the gear rack or the synchronous belt synchronous wheel will generate friction noise during operation, affecting the user experience.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a door and window structure.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0039] like Figures 1 to 10 As shown, a door and window structure in one embodiment of the utility model includes an outer frame 1, a fixed leaf 2 and a movable leaf 3.

[0040] Among them, the outer frame 1 includes a bottom frame 101, a top frame 102 and a pair of side frames 103, the bottom frame 101, the top frame 102 and a pair of side frames 103 are spliced ​​with each other, and the bottom frame 101, the top frame 102 and a pair of side frames 103 are spliced ​​with each other to form an outer frame 1 for installing a fixed fan 2 and a movable fan 3.

[0041] In addition, a pair of side frames 103 are provided with sliding grooves on the sides close to each other, and the movable fan 3 is slidably arranged in the sliding groove. The movable fan 3 can be raised and lowered in the sliding groove to realize the closing and opening of the window.

[0042] like Figures 1 to 10 As shown, the fixed sash 2 is installed on the outer frame 1, and the fixed sash 2 and the movable sash 3 cooperate with each other to form a complete window.

[0043] like Figures 1 to 10 As shown, the movable fan 3 is slidably arranged on the outer frame 1, and the movable fan 3 can move up and down on the outer frame 1, thereby controlling the closing and opening of the window.

[0044] A driving mechanism is installed in the outer frame 1, and the driving mechanism includes a driving motor 301. A pair of output shafts of the driving motor 301 are both connected to a transmission rod 302. When the driving motor 301 is running, the driving motor 301 can drive the pair of transmission rods 302 to rotate.

[0045] In addition, the driving motor 301 and the transmission rod 302 are both installed in the bottom frame 101. When the driving motor 301 is running, the driving motor 301 will drive the transmission rod 302 to rotate.

[0046] Specifically, a plurality of first stabilizing frames 303 are installed in the bottom frame 101, and the transmission rod 302 is rotatably connected to the first stabilizing frames 303. The first stabilizing frames 303 stabilize the transmission rod 302 to prevent the transmission rod 302 from shaking when rotating.

[0047] like Figures 1 to 10 As shown, right angle brackets 304 are installed at the connection between a pair of side frames 103 and the bottom frame 101 . The right angle brackets 304 are used to install the first bevel gear 305 and the second bevel gear 306 . Meanwhile, the right angle brackets 304 are also used to fix the bottom frame 101 and the side frames 103 .

[0048] The first bevel gear 305 and the second bevel gear 306 are rotatably mounted on the right angle frame 304. The first bevel gear 305 and the second bevel gear 306 are meshed with each other, and one end of the transmission rod 302 is fixedly connected to the first bevel gear 305. When the transmission rod 302 rotates, the transmission rod 302 can drive the first bevel gear 305 to rotate. Since the first bevel gear 305 and the second bevel gear 306 are meshed, the first bevel gear 305 can drive the second bevel gear 306 to rotate.

[0049] In addition, a second stabilizing frame 307 is installed in the side frame 103 , and the second stabilizing frame 307 cooperates with the right-angle frame 304 to install the screw rod 308 .

[0050] Specifically, the end of the transmission rod 302 away from the driving motor 301 is connected to a screw assembly, which is connected to the movable fan 3. The screw assembly is used to drive the movable fan 3 to move up and down. Compared with the traditional sprocket chain or gear rack or synchronous belt synchronous wheel driving the movable fan 3 to move up and down, the screw assembly in the present application is less worn when used for a long time, thereby ensuring the service life of the window as a whole, and at the same time reducing the operating noise and improving the user experience. In addition, when the driving motor 301 is suddenly powered off, the movable fan 3 will not fall suddenly, ensuring the safety of the movable fan 3.

[0051] like Figures 1 to 10 As shown, the screw assembly includes a screw 308, which is rotatably connected between the second stabilizing frame 307 and the right-angle frame 304, and one end of the screw 308 is fixedly connected to the second bevel gear 306. When the second bevel gear 306 rotates, the second bevel gear 306 can drive the screw 308 to rotate synchronously.

[0052] The screw rod 308 is threadedly connected with a mounting seat 309, and a first connecting member 310 is mounted on the mounting seat 309, and the first connecting member 310 is fixedly connected to the movable fan 3. When the screw rod 308 rotates, the mounting seat 309 is moved in the side frame 103 by the action of the thread, and then the movable fan 3 can be driven to move up and down, so as to adjust the upper and lower positions of the movable fan 3.

[0053] In addition, a pair of first guide wheels 311 are installed on the first connecting member 310. The first guide wheels 311 roll in the rolling grooves to make the movable fan 3 more stable when lifting and lowering. A rolling groove matching the first guide wheels 311 is provided in the side frame 103.

[0054] Specifically, the screw rod 308 is threadedly connected with a second connecting member 312, the second connecting member 312 is fixedly connected to the movable fan 3, a pair of second guide wheels 313 are rotatably connected to the second connecting member 312, the second guide wheels 313 are arranged in the rolling groove, and the second connecting member 312 is arranged between the second stabilizing frame 307 and the right-angle frame 304. The second connecting member 312 and the second guide wheels 313 can further stabilize the movable fan 3 and ensure the stability of the movable fan 3 when it is lifted or lowered.

[0055] In addition, a handle 314 is connected to one of the first bevel gears 305 . When the driving motor 301 is not powered by electricity, the user can also raise and lower the movable fan 3 by manually cranking the handle 314 .

[0056] Furthermore, a controller 4 is installed in one of the side frames 103, and the controller 4 is used to control the operation of the drive motor 301. An operation panel 1031 is installed on the side wall of the other side frame 103. The operation panel 1031, the drive motor 301 and the controller 4 are electrically connected. The operation panel 1031 is used to control the rotation direction of the drive motor 301, and then the lifting and lowering of the movable fan 3 can be controlled.

[0057] Preferably, a wireless transmission unit is provided in the controller 4, and the user can also control the driving motor 301 to operate through a wireless remote controller, which is convenient for user operation.

[0058] In specific use, when the user needs to open the window, the driving motor 301 is operated through the operation panel 1031 or the wireless remote control, and the driving motor 301 drives the transmission rod 302 and the first bevel gear 305 to rotate. Since the first bevel gear 305 is meshed with the second bevel gear 306, the second bevel gear 306 and the screw rod 308 will also rotate synchronously. The mounting seat 309 and the second connecting member 312 in the side frame 103 are threadedly connected with the screw rod 308. Therefore, when the screw rod 308 rotates, the mounting seat 309 and the second connecting member 312 will move in the side frame 103 due to the action of the thread, and then the movable fan 3 can be driven to descend, so as to realize the window opening operation.

[0059] When the fan needs to be closed, it is only necessary to control the driving motor 301 to rotate in the reverse direction, and the driving motor 301 can drive the transmission rod 302 to rotate in the reverse direction, thereby making the movable fan 3 rise, and completing the fan closing action.

[0060] Compared with the traditional sprocket chain or gear rack or synchronous belt synchronous wheel driving the movable fan 3 to move up and down, the screw rod assembly in the present application has less wear when used for a long time, thereby ensuring the service life of the window as a whole, while also reducing the operating noise and improving the user experience. In addition, when the driving motor 301 suddenly loses power, the movable fan 3 will not fall suddenly, ensuring the safety of the movable fan 3.

[0061] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
