Technical Field

[0001] This utility model relates to the field of door and window installation technology, specifically to a stable window screen structure. Background Technology

[0002] As the first line of defense against mosquitoes and other insects entering the room, the technological development of window screens has always revolved around how to more effectively, more persistently, and more comfortably block flying pests, mainly mosquitoes. Currently, window screens are often installed in conjunction with frames. During installation, the window screen is tucked into the inside of the frame and then fixed with a sealing strip. This method of fixing often results in uneven installation of the window screen or easy damage when subjected to external force. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-12As shown, a stable window screen structure includes a window screen frame 1. A fixing plate 2 is hinged to the bottom and right side of the inner side of the window screen frame 1. Several second springs 11, evenly distributed, are fixedly connected to the top and left side of the inner cavity of the window screen frame 1. A first clamping strip 5 is fixedly connected to the other end of the top second spring 11. A first clamping plate 3 is hinged to one side of the first clamping strip 5. A second clamping strip 15 is fixedly connected to the other end of the left second spring 11. A second clamping plate 14 is hinged to one side of the second clamping strip 15. A guide hole 7 is provided through one side of a limiting protrusion 412. A guide block slidably connected to the inside of the guide hole 7 is fixed to one end surface of the limiting protrusion 412 by a guide post 413. The limiting protrusion 412 can be adjusted through the guide hole 7. To guide and limit movement and improve stability during sliding, a third clamping strip 13 is provided at the opposite end of the first clamping strip 5 and the second clamping strip 15. One side of the third clamping strip 13 is fixedly connected to the second spring 11 at the uppermost corner of the inner side of the screen frame 1. Toothed locking strips 6 are fixedly connected to the inner sides of the fixing plate 2, the first clamping strip 5, the second clamping strip 15, the third clamping strip 13, the first clamping plate 3, the second clamping plate 14, and the third clamping plate 12. The toothed locking strips 6 are evenly distributed. The toothed locking strips 6 increase the friction between the screen and the screen, making the screen more stable and less likely to fall off after fixing. The third clamping strip 13 is hinged to the third clamping plate 12 on one side. A limit structure 4 is provided on one side of the first clamping plate 3, the second clamping plate 14, and the third clamping plate 12.

[0030] The limiting structure 4 includes a limiting block 411 fixed to the surface of the first clamping plate 3, and a guide post 413 fixed inside the first clamping strip 5. A limiting protrusion 412 is slidably connected to the front end of the guide post 413. A first spring 414 is sleeved on the surface of the guide post 413. The two ends of the first spring 414 are fixedly connected to the limiting protrusion 412 and the inside of the first clamping strip 5, respectively. When the screen needs to be fixed or replaced, the limiting block 411 is pulled down. At this time, the limiting block 411 will drive the first clamping plate 3 and the first clamping strip 5 to move downward together. When pulled down to a certain extent, the limiting protrusion 412 inside the first clamping strip 5 will pop out and be located in the groove on the surface of the screen frame 1. At this time, the first clamping plate 3 and the first clamping strip 5 will be fixed, so as to facilitate the installation or replacement of the screen. Similarly, the second clamping plate 14 and the second clamping strip 15, and the third clamping plate 12 and the third clamping strip 13 can be pulled out together.

[0031] The first clamping plate 3, the second clamping plate 14, the fixing plate 2, and the third clamping plate 12 are all threadedly connected to several fixing knobs 8. The other end of the fixing knobs 8 is threadedly connected to the first fixing strip 5, the second fixing strip 15, and the third fixing strip 13, respectively. The fixing knobs 8 are slidably connected to inserts 9. The inserts 9 and the fixing knobs 8 can be used together. Through the use of the inserts 9 and the fixing knobs 8, the first clamping plate 3 can be fixed on the first fixing strip 5, so that the screen is more stable and not easy to fall off. Similarly, the second clamping plate 14 and the second fixing strip 15, and the third clamping plate 12 and the third fixing strip 13 can be fixed by the same inserts 9 and fixing knobs 8.

[0032] Several telescopic rods 10 are fixed to the inner wall of the screen frame 1, and the other end of the telescopic rod 10 is fixed to one side of the first clamping strip 5, the second clamping strip 15 and the third clamping strip 13 respectively. The second spring 11 is sleeved on the surface of the telescopic rod 10. Through the setting of the telescopic rod 10, the second spring 11 can be guided and constrained, so that it maintains a linear motion trajectory during the compression or tension process, effectively avoiding left and right deviation.

[0033] Working principle: When it is necessary to fix the screen mesh, by pulling down the limiting block 411 set on one side of the first clamping plate 3, the first clamping plate 3 and the first fixing strip 5 are moved downward together. When the displacement reaches a certain position, the limiting protrusion 412 sliding inside the first fixing strip 5 will be popped out by the elastic force of the first spring 414, so that the limiting protrusion 412 is located in the groove on the surface of the screen frame 1, thereby limiting the position moved out by the first clamping plate 3. Similarly, by pulling the limiting block 411 set on one side of the second clamping plate 14 and the third clamping plate 12, the second fixing strip 15 and the second clamping plate 14, the third fixing strip 13 and the third clamping plate 12 are moved and fixed on the inner side of the screen frame 1. At this time, the insert 9 is inserted into the fixing knob 8, and the fixing knob 8 is removed by rotation. After all the fixing knobs 8 are removed, the first... The first clamp 3, the second clamp 14, the third clamp 12, and the fixing plate 2 are rotated outwards. At this time, the screen can be laid on the first fixing strip 5, the second fixing strip 15, the third fixing strip 13, and the screen frame 1. Then, the first clamp 3, the second clamp 14, the third clamp 12, and the fixing plate 2 are closed, and the fixing knob 8 is rotated again through the insert block 9 to make it re-screw into the inside of the first fixing strip 5, the second fixing strip 15, the third fixing strip 13, and the screen frame 1, thereby completing the fixing of the screen. Then, the limiting protrusion 412 located on the first fixing strip 5, the second fixing strip 15, and the third fixing strip 13 is pressed into the inside. At this time, the first fixing strip 5, the second fixing strip 15, and the third fixing strip 13 are pulled into the inside of the screen frame 1 by the elastic force of the second spring 11, thereby completing the fixing of the screen.
