[0015] The technical solutions of the present utility model will be clearly described below with reference to the accompanying drawings of the embodiments. It is clear that the described embodiments are only some, not all, of the embodiments of this utility model.

[0016] Referring to Figures 1-3, a convenient folding door panel for home staircases includes a horizontally arranged door panel body 1. Rubber sheets 2 are fixedly connected to both sides of the door panel body 1 for dust prevention. Nylon wool strips 3 are fixedly connected to the outer wall of the rubber sheets 2 to improve the dust prevention effect. Slide grooves are provided on both sides of the door panel body 1. The size of the slide grooves is smaller than that of the rubber sheets 2. Support blocks 4 are slidably connected to the inner wall of the slide grooves to support the rubber sheets 4. Arc-shaped grooves are provided on both the upper and lower sides of the support blocks 4. Ball bearings are rolledly connected to the inner wall of the arc-shaped grooves to reduce the resistance when the support blocks 4 move. The ball bearings pass through the arc-shaped grooves. One end of the support block 4 facing the rubber sheet 2 passes through the slide groove. Four rectangularly distributed guide rods 12 are slidably inserted into the other end of the support block 4 to guide the movement of the support block 4. The end of the guide rods 12 away from the support block 4 is fixedly connected to the inner wall of the slide groove. In this embodiment, a horizontally arranged hollow groove is provided between the two sliding grooves. A horizontally arranged bidirectional screw 5 is provided within the hollow groove to drive the support block 4 to move. The end of the support block 4 furthest from the rubber sheet 2 has a screw hole corresponding to the bidirectional screw 5. Both ends of the bidirectional screw 5 penetrate the hollow groove and extend into the two screw holes respectively. The bidirectional screw 5 and the screw holes are connected by threads. A support ring 13 is fixedly sleeved on the outer wall of the bidirectional screw 5 to support the bidirectional screw 5 and the inner wall of the hollow groove. The upper and lower sides of the support ring 13 are fixedly connected to the inner wall of the hollow groove respectively. Both ends of the bidirectional screw 5 are rotatably sleeved with support rings 13 for support. The two-way screw 5 and the two support rings 13 are fixedly connected to the inner side wall of the slide groove on opposite sides; In this embodiment, a second gear is fixedly sleeved on the outer wall of the bidirectional screw 5 to drive the bidirectional screw 5 to rotate. A first gear 6 is provided in the hollow groove near the bottom to mesh with the second gear and drive the bidirectional screw 5 to rotate. A vertically arranged rotating rod 7 is fixedly connected to the lower end of the first gear 6 to drive the first gear 6 to rotate. A storage groove is provided at the lower end of the door panel body 1. The lower end of the rotating rod 7 passes through the door panel body 1 and extends into the storage groove. The rotating rod 7 and the door panel body 1 are rotatably connected. In this embodiment, a square connecting rod 8 is slidably inserted into the lower end of the rotating rod 7 to drive the rotating rod 7 to rotate. A knob 10 is slidably inserted into the inner wall of the storage slot to drive the connecting rod 8 to rotate. The lower end of the connecting rod 8 is fixedly connected to the upper end of the knob 10. A vertically arranged limiting groove is provided on the outer wall of the connecting rod 8. An anti-detachment block 9 is slidably connected to the inner wall of the limiting groove to prevent the connecting rod 8 from completely detaching from the rotating rod 7. One end of the anti-detachment block 9 passes through the limiting groove and is fixedly connected to the inner wall of the rotating rod 7. Both the knob 10 and the storage slot are hexagonal to prevent the knob 10 from rotating. The inner wall of the storage slot... A magnet 11 is fixedly connected to the top to prevent the knob 10 from coming loose. The knob 10 is made of iron. A pull ring is fixedly connected to the lower end of the knob 10 to facilitate the user in removing the knob 10.

[0017] In this embodiment, firstly, the pull ring is manually pulled to move the knob 10 downwards, which in turn moves the connecting rod 8 downwards, causing the knob 10 to disengage from the storage slot. Next, the knob 10 is manually rotated to drive the connecting rod 8 to rotate, which in turn drives the rotating rod 7 to rotate. The rotating rod 7 drives the first gear 6 to rotate, and the meshing of the first gear 6 and the second gear drives the bidirectional screw 5 to rotate. The bidirectional screw 5, through threaded meshing, drives the two support blocks 4 to move in opposite or opposing directions (the direction of movement is determined by the forward and reverse rotation of the bidirectional screw 5). When the two support blocks 4 move in opposite directions, the rubber sheet 2 can be opened to fill larger gaps for dust prevention. When the two support blocks 4 move relative to each other, the rubber sheet 2 loses support and returns to its original position, filling smaller gaps for dust prevention. After adjustment, the knob 10 is pushed into the storage slot, where the magnetic attraction of the magnet 11 prevents it from detaching. Both the knob 10 and the storage slot are hexagonal in design, which can prevent the knob from being accidentally rotated and loosened, effectively improving the reliability of use.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
