Detailed implementation manners
[0031] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0032] As Figures 1-7 shown in a specific embodiment of a two-way self-closing screen window of the present utility model, it includes a window frame 1, a screen window body 2 rotatably installed on one side of the window frame 1, and a self-closing device 3 installed on the mating surface and / or lower mating surface of the screen window body 2 and the window frame 1. The self-closing device 3 includes a receiving groove 31 opened on the upper end surface or lower end surface of the screen window body 2, a spring member 32 installed in the receiving groove 31, and a reset stop block 33 installed on the window frame 1 and disposed opposite to the screen window body 2. The spring member 32 includes a spiral spring portion 321 and a first reset rod 323 and a second reset rod 324 respectively disposed at both ends thereof. Among them, both the first reset rod 323 and the second reset rod 324 extend out of the screen window body 2. The reset stop block 33 is disposed on the window frame 1 between the corresponding first reset rod 323 and second reset rod 324, and the side wall of the reset stop block 33 is in blocking cooperation with the corresponding first reset rod 323 and second reset rod 324.
[0033] In this embodiment, the reset block 33 can be a bolt, which is installed on the side of the window frame 1 facing the screen window body 2 through threaded cooperation. The reset block 33 can also be fixed on the window frame 1 by welding.
[0034] Specifically, when the screen window body 2 is opened outward relative to the window frame 1, the first reset rod 323 and the reset block 33 are in a blocking cooperation. When the outward opening thrust disappears, under the elastic force of the spring member and the elastic force of the first reset rod 323, the screen window body 2 is pulled back to the closed position. When the screen window body 2 is opened inward relative to the window frame 1, the second reset rod 35 and the reset block 33 are in a blocking cooperation. When the inward opening pulling force disappears, under the elastic force of the spring member and the elastic force of the second reset rod 35, the screen window body 2 is pulled back to the closed position.
[0035] As Figure 1 and Figure 2 shown, the utility model designs the screen window body 2 and the window frame 1 into a side-rotating opening and closing structure. An opening and closing handle is installed on the edge of the screen window body 2, which can realize the outward and inward opening and closing of the screen window body 2. An automatic closing device 3 is arranged on the upper mating surface and / or the lower mating surface of the screen window body 2 and the window frame 1. By using the reset elastic force of the spring member 32, the first reset rod 323 and the second reset rod 35 relative to the reset block 33, the opened screen window body 2 is automatically pulled back to the position closed to the window frame 1, solving the problems of manual closing of the window screen and misalignment of the magnetic adsorption type screen window in the prior art. While realizing the automatic closing of the screen window, the whole screen window structure is simple and the closing is stable and reliable.
[0036] As Figures 3 to 6 shown, the head end of the spiral spring part 321 in this embodiment is connected to the first reset rod 323, and the tail end of the spiral spring part 321 is connected to the second reset rod 324 through the vertical rod 322. It should be further noted that the automatic closing device 3 in this embodiment further includes a guide groove 34 opened on the upper end surface and / or the lower end surface of the screen window body 2; the guide groove 34 is communicated with the corresponding receiving groove 31, and the vertical rod 322 is arranged in the receiving groove 31. Taking the automatic closing device 3 arranged on the upper mating surface of the screen window body 2 and the window frame 1 as an example, during installation, the spiral spring part 321 is installed in the receiving groove 31, and the vertical rod 322 is correspondingly installed in the guide groove 34. The setting of the guide groove 34 on the one hand leaves a space for placing the vertical rod 322, and on the other hand can prevent the spiral spring part 321 from rotating excessively, causing the first reset rod 323 and / or the second reset rod 35 to fall off from the reset block 33.
[0037] As Figure 7As shown in the figure, this embodiment further includes a suction component 35 for automatic suction. The suction component 35 includes a first groove opened on the opening and closing side of the screen window body 2, a first magnet fixedly installed in the first groove, a second groove opened on the opening and closing side wall of the window frame 1, and a second magnet fixedly installed in the second groove. Among them, the first groove and the second groove are arranged opposite to each other, and the mating surfaces of the first magnet and the second magnet have opposite magnetic poles. When the screen window body 2 is opened outward or inward relative to the window frame 1, under the action of the restoring force of the first restoring rod 323 or the second restoring rod 35 and the restoring block 33, when the screen window body 2 is pulled back to the closed position close to the window frame 1, under the action of the mutual suction force of the first magnet and the second magnet, the closing of the screen window body 2 and the window frame 1 is realized. By adopting the magnetic suction method, the mutually approaching screen window body 2 and the window frame 1 can be accurately and quickly closed, avoiding the situation that the closing time is too long due to inertia, and preventing mosquitoes and dust from entering the room.
[0038] As an implementation manner, to enable the screen window body 2 to be opened outward and inward relative to the window frame 1, the screen window body 2 is rotatably installed on the window frame 1 through a rotating shaft 4. Of course, other rotating mechanisms that can achieve outward or inward opening can also be used. Here, there is no absolute limitation on the rotating mechanism of the screen window body 2 and the window frame 1.
[0039] It should be understood that the specific embodiments described above are only used to explain the present invention and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
