Description

Technical Field

[0001] This utility model belongs to the field of screen window assembly and disassembly technology, and particularly relates to a quick assembly and disassembly structure for door and window screens. Background Technology

[0002] Window screens are mesh protective devices installed on doors and windows, primarily for mosquito prevention and dust filtration. Their core function is mosquito control, preventing insects from entering the room and avoiding bites when windows are open. They also filter some dust and debris entering the room, improving indoor air quality; block some views, protecting privacy; screens with safety railings can also prevent children from falling; furthermore, different styles and colors of screens can also have a decorative effect on the room.

[0003] The installation steps for traditional door and window screens are as follows: First, the user needs to place the screen frame in the installation position, then pass multiple bolts through the frame one by one and insert them into the installation holes, and finally tighten all the bolts in sequence until the frame is fixed.

[0004] This installation method has obvious limitations: first, tools must be used to tighten each bolt individually, which takes a long time; second, if the installer forgets to bring the tools or there are no corresponding tools on site, the tools must be obtained again before the operation can continue, which will further increase the installation time and ultimately reduce the installation efficiency of doors and windows. In view of this, we propose a quick-installation structure for doors and windows. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release and assembly structure for doors, windows, and screens to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a quick-assembly and disassembly structure for door and window screens, including a frame and a screen, wherein the screen is mounted on the frame, and further includes:

[0007] Several bolts are rotatably connected to one side of the frame;

[0008] A plurality of gear slots are formed within a frame and connected to the outside. A first bevel gear and a second bevel gear are rotatably connected within each of the plurality of gear slots, and the first bevel gear and the second bevel gear mesh with each other. One end of each of the plurality of first bevel gears passes through the inner wall of the plurality of gear slots and extends into the frame and is fixedly connected to one end of a plurality of bolts.

[0009] Two connecting slots are formed within the frame and are respectively connected to two corresponding gear slots. A connecting rod is rotatably connected to each of the two connecting slots, and the two ends of the two connecting rods extend into several gear slots and are respectively fixedly connected to several second bevel gears.

[0010] A drive assembly, located within the frame, is used to drive two of the first bevel gears to rotate.

[0011] In this technical solution, it is ensured that the user can rotate several bolts simultaneously, allowing the entire device to be quickly installed in a suitable position.

[0012] In the above technical solution, the driving component further includes:

[0013] The movable groove is located within the frame and communicates with two gear slots. Two synchronous pulleys are rotatably connected within the movable groove. One end of each synchronous pulley penetrates the inner wall of the movable groove and extends into one of the two gear slots. A transmission rod is fixedly connected to one end of each synchronous pulley, and one end of each transmission rod is fixedly connected to one of the two first bevel gears. A rotating rod is fixedly connected to one of the synchronous pulleys, and one end of the rotating rod penetrates the inner wall of the movable groove and extends to the outside. A synchronous belt meshes between the two synchronous pulleys.

[0014] The tensioning assembly, located within the frame, is used to control the tension of the timing belt.

[0015] In this technical solution, it is ensured that the user can drive two of the first bevel gears to rotate simultaneously.

[0016] In the above technical solution, the tensioning component further includes:

[0017] The first slide groove is formed on the inner wall of the movable groove. A tensioning wheel is slidably connected in the first slide groove. A second slide groove is formed on the inner wall of the first slide groove and communicates with the outside. A slide rod that is fixedly connected to the tensioning wheel is slidably connected in the second slide groove.

[0018] A threaded groove is formed on the periphery of the slide bar, and a threaded sleeve is threadedly connected to the threaded groove, with the threaded sleeve located on one side of the frame.

[0019] This technical solution ensures that users can control the tension of the timing belt.

[0020] In the above technical solution, further, the tensioning wheel is slidably connected to the movable groove, one end of the slide rod is slidably connected to the first slide groove, the slide rod is provided with anti-slip texture on its periphery, and the threaded sleeve is provided with anti-slip texture on its periphery.

[0021] In this technical solution, it is ensured that when the tensioning wheel slides, it can slide normally in the movable groove, and when the slide rod slides, one end of the slide rod can slide normally in the first slide groove. At the same time, because the slide rod and the threaded sleeve are provided with anti-slip textures on their circumferences, when the user rotates the slide rod or the threaded sleeve by hand, they will be affected by the anti-slip textures on the circumferences of the slide rod or the threaded sleeve, reducing the problem of hand slippage.

[0022] In the above technical solution, one end of each of the two synchronous pulleys is rotatably connected to two of the gear slots, and the two transmission rods are respectively located in two of the gear slots and rotatably connected to two of the gear slots. The circumference of the transmission rod is provided with anti-slip texture.

[0023] In this technical solution, it is ensured that when the two synchronous pulleys rotate, one end of each pulley can rotate normally within two of the gear slots, and that when the two transmission rods rotate, each transmission rod can rotate normally within two of the gear slots respectively. At the same time, because the rotating rod has anti-slip textures on its periphery, when the user rotates the rotating rod by hand, the anti-slip textures on the periphery of the rotating rod will affect the user's hand, reducing the problem of hand slippage.

[0024] In the above technical solution, furthermore, the threads on the several bolts have the same direction of rotation and the same thread pitch, and one end of the several first bevel gears is rotatably connected to the frame.

[0025] In this technical solution, because the threads on several bolts have the same direction of rotation and the same thread pitch, when several bolts rotate, they will be acted upon by the threads of the mounting holes and enter the mounting holes at the same time, ensuring that when several first bevel gears rotate, one end of several first bevel gears can rotate normally within the frame.

[0026] The beneficial effects of this utility model are:

[0027] 1. This quick-installation structure for doors and windows screens utilizes a first bevel gear, a synchronous pulley, a transmission rod, a rotating rod, and a synchronous belt. This allows the user to simultaneously rotate two of the first bevel gears. Through bolts, the first bevel gear, the second bevel gear, and a connecting rod, when two of the first bevel gears rotate, the other two will also rotate simultaneously. This allows several first bevel gears to drive several bolts to rotate simultaneously. This design eliminates the need for users to tighten bolts individually, reducing installation time. Furthermore, even when users lack the necessary tools, they can still install doors and windows screens, further improving installation efficiency.

[0028] 2. This quick-release and disassembly structure for doors and windows, through the setting of a first sliding groove, a tensioning wheel, a second sliding groove, and a sliding rod, allows the user to drive the tensioning wheel to compress the synchronous belt. Through the setting of threaded grooves and threaded sleeves, the tensioning wheel can be fixed when it moves to a preset position. The design of the above structure allows the user to control the tension of the synchronous belt, preventing the synchronous belt from loosening during long-term use and improving the stability of the overall device.

[0040] Example 1: This example provides a quick-release structure for door and window screens, including a frame 1 and a screen 2, with the screen 2 mounted on the frame 1. It also includes:

[0041] Several bolts 3 are rotatably connected to one side of frame 1;

[0042] Several gear slots 4 are formed inside the frame 1 and connected to the outside. A first bevel gear 5 and a second bevel gear 6 are rotatably connected in each of the several gear slots 4, and the first bevel gear 5 and the second bevel gear 6 mesh with each other. One end of each of the several first bevel gears 5 passes through the inner wall of the several gear slots 4 and extends into the frame 1 and is fixedly connected to one end of each of the several bolts 3.

[0043] Two connecting slots 7 are formed inside the frame 1 and are respectively connected to two corresponding gear slots 4. Connecting rods 8 are rotatably connected in both connecting slots 7, and the two ends of the two connecting rods 8 extend into several gear slots 4 and are respectively fixedly connected to several second bevel gears 6.

[0044] The drive assembly is located within the frame 1 and is used to drive the two first bevel gears 5 to rotate.

[0045] In use, the user places the frame 1 in the installation position by hand, then inserts several bolts 3 into the installation holes. Subsequently, the user drives two of the first bevel gears 5 to rotate via the drive assembly, which in turn drives two of the second bevel gears 6 to rotate. These two second bevel gears 6 then drive two other second bevel gears 6 via two connecting rods 8, which in turn drive two more first bevel gears 5 to rotate. As the first bevel gears 5 rotate, they drive several bolts 3 to rotate, ensuring that the user can simultaneously drive several bolts 3 to rotate, allowing the entire device to be quickly installed in the appropriate position.

[0046] Example 2: This example provides a quick-release structure for door and window screens. In addition to the technical solutions of the above examples, it also has the following technical features, including a driving component:

[0047] The movable groove 9 is opened inside the frame 1 and is connected to two gear grooves 4. Two synchronous pulleys 10 are rotatably connected inside the movable groove 9. One end of the two synchronous pulleys 10 passes through the inner wall of the movable groove 9 and extends into the two gear grooves 4 respectively. One end of each of the two synchronous pulleys 10 is fixedly connected to a transmission rod 11, and one end of each of the two transmission rods 11 is fixedly connected to two of the first bevel gears 5 respectively. One of the synchronous pulleys 10 is fixedly connected to a rotating rod 12, and one end of the rotating rod 12 passes through the inner wall of the movable groove 9 and extends to the outside. A synchronous belt 13 meshes between the two synchronous pulleys 10.

[0048] The tensioning assembly, located within frame 1, is used to control the tension of the timing belt 13.

[0049] In use, the user manually rotates the rotating rod 12, causing one of the synchronous pulleys 10 to rotate within the movable groove 9. This causes one synchronous pulley 10 to drive the other synchronous pulley 10 to rotate via the synchronous belt 13. When both synchronous pulleys 10 rotate, they will drive two of the first bevel gears 5 to rotate via two transmission rods 11, ensuring that the user can drive both of the first bevel gears 5 to rotate simultaneously.

[0050] Example 3: This example provides a quick-release structure for door and window screens. In addition to the technical solutions of the above examples, it also has the following technical features: the tensioning component includes:

[0051] The first slide groove 14 is formed on the inner wall of the movable groove 9. A tensioning wheel 15 is slidably connected in the first slide groove 14. A second slide groove 16, which is connected to the outside, is formed on the inner wall of the first slide groove 14. A slide rod 17, which is fixedly connected to the tensioning wheel 15, is slidably connected in the second slide groove 16.

[0052] The threaded groove 18 is formed on the periphery of the slide bar 17, and a threaded sleeve 19 is threadedly connected to the threaded groove 18, and the threaded sleeve 19 is located on one side of the frame 1.

[0053] In use, the user slides the slide bar 17 by hand, causing the tension wheel 15 to move along the first groove 14. This causes the tension wheel 15 to compress the timing belt 13. When the tension wheel 15 moves to the appropriate position, the user rotates the threaded sleeve 19 by hand, causing the threaded sleeve 19 to move towards the frame 1 under the action of the threaded groove 18. This causes the threaded sleeve 19 to be tightly pressed against the frame 1, fixing the slide bar 17 inside the frame 1 and preventing it from rotating. This ensures that the user can control the tension of the timing belt 13.

[0054] Example 4: This example provides a quick-release structure for doors and windows screens. In addition to the technical solutions of the above examples, it also has the following technical features: the tensioning wheel 15 is slidably connected to the movable groove 9, one end of the slide rod 17 is slidably connected to the first slide groove 14, the slide rod 17 is provided with anti-slip texture on its periphery, and the threaded sleeve 19 is provided with anti-slip texture on its periphery.

[0055] Specifically, it is ensured that when the tensioning wheel 15 slides, it can slide normally within the movable groove 9, and that when the slide rod 17 slides, one end of the slide rod 17 can slide normally within the first slide groove 14. At the same time, because the slide rod 17 and the threaded sleeve 19 are provided with anti-slip textures on their circumferences, when the user rotates the slide rod 17 or the threaded sleeve 19 by hand, the anti-slip textures on the circumferences of the slide rod 17 or the threaded sleeve 19 will affect the user, reducing the problem of hand slippage.

[0056] Example 5: This example provides a quick-release structure for doors and windows screens. In addition to the technical solutions of the above examples, it also has the following technical features: one end of each of the two synchronous wheels 10 is rotatably connected to one of the two gear slots 4; two transmission rods 11 are respectively located in one of the two gear slots 4 and are rotatably connected to one of the two gear slots 4; and anti-slip textures are provided on the periphery of the rotating rod 12.

[0057] Specifically, it is ensured that when the two synchronous pulleys 10 rotate, one end of each pulley 10 can rotate normally within one of the two gear slots 4, and that when the two transmission rods 11 rotate, each transmission rod 11 can rotate normally within one of the two gear slots 4 respectively. At the same time, because the rotating rod 12 has anti-slip texture on its circumference, when the user rotates the rotating rod 12 by hand, the anti-slip texture on the circumference of the rotating rod 12 will affect the user's hand, reducing the problem of hand slippage.

[0058] Example 6: This example provides a quick-assembly and disassembly structure for doors and windows and screens. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on several bolts 3 have the same direction of rotation and the same thread pitch; one end of several first bevel gears 5 is rotatably connected to the frame 1.

[0059] Because the threads on several bolts 3 have the same direction of rotation and the same thread pitch, when several bolts 3 rotate, they will be acted upon by the threads of the mounting holes and enter the mounting holes at the same time, ensuring that when several first bevel gears 5 rotate, one end of several first bevel gears 5 can rotate normally within the frame 1.

[0060] Working principle:

[0061] In use, the user places the frame 1 in the installation position by hand, then inserts several bolts 3 into the installation holes. The user then rotates the rotating rod 12 by hand, causing one of the synchronous pulleys 10 to rotate in the movable groove 9. This causes one synchronous pulley 10 to drive another synchronous pulley 10 to rotate via the synchronous belt 13. When the two synchronous pulleys 10 rotate, they will drive two of the first bevel gears 5 to rotate via two transmission rods 11. These two first bevel gears 5 will then drive two of the second bevel gears 6 to rotate via two connecting rods 8. These two second bevel gears 6 will then drive two more second bevel gears 6 to rotate via two connecting rods 8. This allows the other two second bevel gears 6 to drive two more first bevel gears 5 to rotate. When the first bevel gears 5 rotate, they will drive several bolts 3 to rotate, ensuring that the user can simultaneously drive several bolts 3 to rotate, allowing the entire device to be quickly installed in the appropriate position.

[0062] In use, the user slides the slide bar 17 by hand, causing the slide bar 17 to drive the tension wheel 15 to move along the first groove 14, thus stopping the tension wheel 15 from squeezing the timing belt 13. When the tension wheel 15 moves to the appropriate position, the user rotates the threaded sleeve 19 by hand, causing the threaded sleeve 19 to move towards the frame 1 under the action of the threaded groove 18, so that the threaded sleeve 19 is tightly squeezed onto the frame 1, fixing the slide bar 17 inside the frame 1 and preventing it from rotating, ensuring that the user can control the tension of the timing belt 13.
