[0002] With social development, the demand for personalized high-end residences in cities is increasing, and the number of extra-large openings is also growing. Most design solutions involve extra-large sliding doors. Currently, the main screen door solutions are traditional sliding screen panels and folding screen doors. However, sliding screen panels need to be added to the outside or inside of the door frame, which has low aesthetic appeal and is difficult to install. Extra-large sliding screen doors are generally installed later, resulting in high transportation and installation costs. When choosing folding screen doors, the visibility and wind resistance are extremely low, so customer choice is low. Furthermore, since the screen door folds down, it also occupies part of the door frame cavity width, which reduces the light transmission area. Therefore, to address the above problems, a concealed sliding screen door structure is proposed. Utility Model Content

It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 like Figure 1-10As shown, a concealed sliding screen door structure includes a door frame 1. The left and right ends of the inner side of the door frame 1 are both in contact with a fixed cover 2. The upper and lower ends of one side of the fixed cover 2 are both fixedly connected to a track 4 that contacts the door frame 1. A roller 5 is provided inside the fixed cover 2. A flexible support 6, penetrating the fixed cover 2, is fixedly connected to the outer side of the roller 5 and contacts the fixed cover 2. The other end of the flexible support 6 is fixedly connected to a support rod 7 that contacts the track 4. Fixed shafts 8, rotatably connected to the fixed cover 2, are fixedly connected to the upper and lower ends of the roller 5. A spring 9 is fixedly connected to the outer side of the fixed shaft 8, and the other end of the spring 9 is fixedly connected to the fixed cover 2. Symmetrically distributed screen mesh 14 is provided on the outer side of the flexible support 7.

[0024] Furthermore, such as Figure 1 , Figure 2 , Figure 8 and Figure 10 As shown, both the upper and lower ends of the door frame 1 are spirally connected with bolts 3 that penetrate the door frame 1, and the bolts 3 are spirally connected to the fixing cover 2. By inserting the screen door structure from both sides of the door frame 1, and then manually using existing tools to rotate the bolts 3 to spirally connect the screen door structure to the door frame 1 and the fixing cover 2, it is convenient to install the screen door structure inside the door frame 1.

[0025] Furthermore, such as Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, guide blocks 10 located inside the track 4 are fixedly connected to both the upper and lower ends of the support rod 7. A symmetrically distributed ball bearing is rotatably connected to one end of the outer side of the guide block 10, and the ball bearing on the outer side of the guide block 10 contacts the track 4. When the flexible support frame 6 with the screen mesh 14 on the outer side of the screen door structure is pulled out, the guide blocks 10 at both ends of the support rod 7 are guided by the track 4, and then the guide blocks 10 are made to contact the track 4 through the ball bearing, which can reduce the friction between the guide blocks 10 and the track 4 when the support rod 7 is pushed.

[0026] Furthermore, such as Figure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 9 As shown, a locking rod 11 is slidably connected to the inner top of the support rod 7, and one side of the top of the locking rod 11 is inclined. The inclined part of the top of the locking rod 11 is engaged with the top rail 4. A push block 12 is fixedly connected to the outer bottom of the locking rod 11, and the push block 12 is in contact with the support rod 7. A spring 13 is fixedly connected to the bottom of the locking rod 11, and the other end of the spring 13 is fixedly connected to the support rod 7. By pushing the locking rod 11 with the push block 12, the spring 13 is compressed, which further disengages the locking rod 11 from the top rail 4, making it easier to release the limit of the support rod 7 and perform concealed operation of the screen door structure.

[0027] Furthermore, such as Figure 6 and Figure 7 As shown, a double-sided hook and loop fastener 15 is fixedly connected to the inner side of the flexible support 7. A hook and loop fastener 16 is attached to the outer side of the double-sided hook and loop fastener 15. The hook and loop fastener 16 is fixedly connected to the mesh 14. By pulling the modular mesh 14, the hook and loop fastener 16 can be separated from the double-sided hook and loop fastener 15 fixed inside the flexible support 6, making it convenient to remove the mesh 14 for cleaning or replacement as needed.

[0028] The principle of pulling out, tightening, and concealing the screen door structure: First, insert the screen door structure from both sides of the door frame 1, then connect the screen door structure to the door frame 1. After connection, when the screen door structure needs to be used, manually pull the support rod 7 to move the guide block 10 along the track 4. At this time, the support rod 7 will also pull the flexible support frame 6 with the screen 14 on the outside out from the outside of the roller 5. During the above operation, the roller 5 will also drive the fixed shaft 8 to rotate, and the spring 9 will continuously contract. When the support rod 7 moves, the internal locking rod 11 will engage with the spring 13 under the elastic force of the spring. When the top track 4 is engaged, the flexible support 6 with the outer mesh 14 will be pulled out completely from the outside of the roller 5, thus enabling the flexible support 6 with the outer mesh 14 to be pulled out and tightened for use. When the screen door structure is no longer needed, simply release the engagement between the locking rod 11 and the top track 4, and then allow the flexible support 6 with the outer mesh 14 to be rewound to the outside of the roller 5 under the restoring force of the spring 9. At this time, the flexible support 6 with the outer mesh 14 will be completely concealed in the fixed cover 2 inside the door frame 1.

[0029] The above are preferred embodiments of the present invention. The basic principles, main features, and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope thereof. All such changes and modifications fall within the scope of the present invention as claimed.
