Detailed Implementation

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1 to 11 As shown, this utility model embodiment provides a door and window structure with a screen, including a window frame 1, a glass window sash 2, a positioning frame 3, a screen body 4, and a positioning connection mechanism 5; The positioning frame 3 is fixedly installed on the inner wall of the window frame 1, and the frame of the screen body 4 has an L-shaped stepped structure (e.g., Figure 4The screen body 4 is installed inside the window frame 1 to block it, and is used to position and install the screen body 4; the positioning connection mechanism 5 is set on the frame of the screen body 4 and the positioning frame 3, and is used to install the screen body 4 inside the window frame 1 and fix it.

[0021] In some practical applications, the glass window sash 2 is installed on the window frame 1 via hinges, and the glass window sash 2 opens inward.

[0022] In summary: When the screen body 4 is installed, the positioning frame 3 inside the window frame 1 limits and blocks the screen body 4 from all sides, ensuring that the screen body 4 is precisely positioned and inserted into the interior of the positioning frame 3. This ensures that the screen body 4 can be quickly and accurately aligned with the installation position, preventing it from loosening or shifting during use. The locking mechanism of the positioning connection mechanism 5 generates a connecting force to install the screen body 4 into the positioning frame 3. When needed, the positioning connection mechanism 5 can be used to unlock the screen body 4, allowing for its removal. When the glass sash 2 is opened inward, it rotates towards the interior space, thus freeing up the entire operating space inside the window frame 1. This allows users to install, remove, or clean the screen body 4 installed inside the window frame 1 without any obstruction, greatly improving the convenience and safety of use.

[0023] The positioning and connecting mechanism 5 described above includes at least the following three embodiments: like Figure 5 , Figure 6 and Figure 7 As shown, here is an embodiment of the positioning and connecting mechanism 5: In some embodiments, the positioning connection mechanism 5 includes a first positioning block 501 fixedly installed on the positioning frame 3. The surface of the first positioning block 501 is provided with a first insertion recess 502. The edge of the screen body 4 frame is provided with a first positioning groove 503. When the screen body 4 is positioned and installed with the positioning frame 3, the first positioning block 501 is inserted into the first positioning groove 503. A first slider 504 is slidably installed in the first positioning groove 503. A locking pin 505 is fixedly installed on one end face of the first slider 504. A spring 506 is fixedly connected between the other side wall of the first slider 504 and one side wall of the first positioning groove 503.

[0024] In summary: During installation, first place the screen body 4 into the positioning frame 3, so that the first positioning block 501 fixed on the positioning frame 3 is inserted into the first positioning groove 503 on the edge of the screen frame to complete the initial positioning. Finally, locking is achieved by operating the first slider 504. Through the elastic force of the spring 506, the locking pin 505 at its end is inserted into the first insertion recess 502 opened on the surface of the first positioning block 501, thereby achieving mechanical interlocking.

[0025] In some practical applications, limiting grooves are provided on both sides of the first positioning groove 503, and protrusions are provided on both sides of the first slider 504. The slider slides in the limiting grooves through the protrusions to guide the sliding of the first slider 504.

[0026] When the first positioning block 501 is operated, the protrusions on both sides of it will be inserted and slide along the limiting groove, so that the movement of the first positioning block 501 is strictly constrained in a single straight line direction, effectively preventing it from twisting, tilting or jamming during the push and pull process, and ensuring that the locking pin 505 can always be accurately aligned with the first insertion recess 502.

[0027] In another practical application, when the screen body 4 and the positioning frame 3 are installed, the first positioning block 501 is inserted into the first positioning groove 503. At this time, the locking pin 505 is correspondingly set with the first insertion recess 502 on the surface of the first positioning block 501.

[0028] When the screen body 4 is installed in place and the first positioning block 501 is fully inserted into the first positioning groove 503, the tip of the locking pin 505 at the end of the first slider 504 will move to a position that is directly opposite the opening of the first insertion recess 502 on the surface of the first positioning block 501 under the action of the spring 506.

[0029] like Figure 8 and Figure 9 As shown, here is a second embodiment of the positioning and connecting mechanism 5: In some embodiments, the positioning connection mechanism 5 includes a second positioning block 511 fixedly installed on the positioning frame 3. The surface of the second positioning block 511 is provided with a second insertion recess 512, and a permanent magnet 513 is fixedly installed in the second insertion recess 512. A second positioning groove 514 is provided at the edge of the screen body 4 frame, and a second slider 515 is slidably installed in the second positioning groove 514. An armature pin 516 is fixedly installed at the end of each of the second sliders 515.

[0030] In summary: A permanent magnet 513 is fixedly installed at the bottom of the second insertion recess 512 of the second positioning block 511. An armature pin 516 made of iron is installed at the end of the second slider 515 on the screen body 4 frame. When the screen body 4 is pushed into place, the strong magnetic field generated by the permanent magnet 513 will automatically attract the armature pin 516, causing it to overcome slight resistance and slide downward until it is firmly attracted to the permanent magnet 513, thereby achieving fast, quiet, passive automatic locking.

[0031] In some practical applications, limiting grooves are provided on both sides of the second positioning groove 514, and protrusions are provided on both sides of the second slider 515. The slider slides in the limiting grooves through the protrusions to guide the second slider 515.

[0032] The protrusions on both sides of the second slider 515 will be inserted and slide along the limiting groove, so that the movement of the second slider 515 is strictly constrained in a single straight line direction, effectively preventing it from twisting, tilting or jamming during the push and pull process, and ensuring that the armature pin 516 can always be accurately aligned with the second insertion recess 512.

[0033] like Figure 10 and Figure 11 As shown, this is embodiment three of the positioning and connecting mechanism 5: In some embodiments, the positioning connection mechanism 5 includes a third positioning block 521 fixedly installed on the positioning frame 3. The surface of the third positioning block 521 is provided with a threaded recess 522, and the surface of the screen body 4 is provided with a third positioning groove 523. A threaded knob 524 is rotatably inserted at the edge of the frame of the screen body 4, and the end of the threaded knob 524 is threadedly inserted into the threaded recess 522 to fix the screen body 4.

[0034] More specifically, during installation, the screen body 4 is first placed into the positioning frame 3, so that the third positioning block 521 fixed on the positioning frame 3 enters the third positioning groove 523 on the screen body 4 for initial positioning. The threaded knob 524 is rotatably installed on the edge of the screen body 4 through a bearing or loose fit hole. Rotating the threaded knob 524 causes its external thread to be screwed into the threaded recess 522 opened on the surface of the third positioning block 521. Through the huge mechanical force generated by the threaded pair, the screen body 4 is tightly fixed on the positioning frame 3.

[0035] In some practical applications, when the screen body 4 is inserted into the positioning frame 3, the end of the threaded knob 524 is correspondingly set with the threaded recess 522 on the surface of the third positioning block 521.

[0036] Once the screen body 4 is installed in place, the third positioning block 521 fully enters the third positioning groove 523. At this time, the threaded end of the threaded knob 524 will naturally and accurately align with the entrance of the threaded recess 522 on the surface of the third positioning block 521.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
