[0003] Traditional sliding doors typically consist of a door frame, a track system, pulleys or rails, a door leaf, and mechanisms such as locks and handles. The track system is a guide rail mounted on the door frame or on the floor, allowing the door leaf to slide smoothly. The track system typically includes upper and lower rails, while the pulley is a component mounted on the door leaf or inside the door frame that enables the door leaf to slide along the track.

[0004] However, there are large gaps between the door panels of traditional sliding doors. The gaps will cause noise to enter the room from the outside, reducing the sound insulation performance. The gaps will also allow dust and small insects to enter the room, affecting cleaning and hygiene, and reducing the practicality of this sliding door. Utility Model Content

[0031] Reference Figure 1-Figure 5 The utility model provides an embodiment: a multifunctional sliding door, including a door frame 1, a hanging rail 2 is fixedly connected to the top of the door frame 1, a plurality of supporting platforms 3 are fixedly connected to the side walls of the door frame 1, a double-track slide 4 is opened inside the hanging rail 2, the hanging rail 2 and the double-track slide 4 inside it provide a sliding track for the sliding door, a plurality of hanging platforms 5 are arranged inside the hanging rail 2, the hanging platform 5 is used to connect the door panel 9 at the bottom, the top of the hanging platform 5 is rotatably connected to the pulley 6, the pulley 6 ensures the stable sliding of the sliding door, the pulley 6 is slidably connected to the double-track slide 4, the hanging platform 5 The bottom is fixedly connected with a folding edge 7, which shortens the distance between multiple door panels 9. The bottom of the folding edge 7 is fixedly connected with a connecting piece 8, which is used to fix the door panels 9. The outer wall of the connecting piece 8 is fixedly connected with the door panels 9. The bottom of the door frame 1 is fixedly connected with a slide 10, and the inside of the slide 10 is rotatably connected with rollers 11. The slide 10 and the rollers 11 ensure the stability of the door panels 9 during the sliding process. The door frame 1 is fixedly connected with an inner platform 12. An anti-collision component is arranged inside the door frame 1, and the anti-collision component is used to buffer the impact force between the door frame 1 and the door panels 9.

[0032] Specifically, in this sliding door, the door frame 1 serves as the supporting frame of the overall structure. A plurality of supports 3 are provided on both sides of the inner wall of the door frame 1. These supports 3 support the hanging rail 2 at the top, providing it with additional stability, so that it remains stable during use and prevents the hanging rail 2 from deforming or shaking due to long-term use. The double-track slide 4 inside the support 3 provides a smooth sliding track for the pulley 6. When the sliding door is in use, the movement of the door panel 9 enables the pulley 6 to slide smoothly inside the double-track slide 4, thereby realizing the smooth opening and closing function of the sliding door. The bottom of the hanging platform 5 is fixedly connected to the folding edge 7, and the folding edge 7 is fixedly connected to the folding edge 7. The design is similar to the thickness of the door panel 9. This approximate distance makes the gaps between multiple door panels 9 more compact than traditional sliding doors. Smaller gaps help to effectively reduce the spread of noise. Secondly, the reduction in gaps reduces the exchange of indoor and outdoor air, thereby significantly improving the thermal insulation performance of the door, which can help maintain a stable indoor temperature. In addition, smaller gaps can also help prevent dust, pollen and other tiny particles from entering the room, thereby improving indoor air quality, reducing health problems caused by indoor air pollution, improving the practicality of the door in many aspects, and providing users with a more comfortable and healthy use experience.

[0033] Reference Figure 6 and Figure 7 The anti-collision component includes a damping rod 16, which provides a first buffer between the door frame 1 and the door panel 9. The damping rod 16 is arranged inside the door frame 1. A plurality of fixing members 13 are fixedly connected to the inside of the door frame 1. The side walls of the fixing members 13 are fixedly connected to the fixing platforms 14. The fixing members 13 are fixedly connected to the inside of the door frame 1 symmetrically up and down. A fixing column 15 is fixedly connected between the fixing platforms 14. The damping rod 16 is fixedly connected to the side wall of the fixing column 15. One end of the damping rod 16 is fixedly connected to a strike plate 17. The strike plate 17 prevents the door panel 9 from colliding with the door panel 9. When the frames 1 collide with each other, the outer wall of the fixed column 15 is slidably connected to a plurality of connecting rings 18, and the plurality of connecting rings 18 can disperse the impact force. A spring 19 is arranged between the connecting rings 18, and the spring 19 provides a second buffer and can reset the connecting ring 18. The two ends of the spring 19 are respectively fixedly connected to the inside of the plurality of connecting rings 18, and the side walls of the connecting rings 18 are fixedly connected to the turntable 20, and the outer walls of the turntable 20 are rotatably connected to the connecting frame 21, and the side wall of the connecting frame 21 is rotatably connected to the slider 22, and the slider 22 is slidably connected to the inside of the collision plate 17.

[0034] Specifically, if a large force is used to push or pull the door panel 9, the door panel 9 will first touch the strike plate 17 provided on the door frame 1 when it hits the edge of the door frame 1. After being subjected to the impact force, the strike plate 17 will move toward the fixed platform 14. During this process, the damping rod 16 will buffer the strike plate 17, significantly reducing the intensity of the impact force. The damping rod 16 absorbs and disperses the impact force through its built-in damping mechanism, avoiding direct impact. As the strike plate 17 moves, multiple sliders 22 on its side wall will slide on the side wall of the strike plate 17. The sliding of the slider 22 drives the rotation of the connecting frame 21, and the inclination angle of the connecting frame 21 changes accordingly, so that the other side of the connecting frame 21 The turntable 20 is pulled, and the movement of the turntable 20 causes the connecting ring 18 on its side wall to slide on the outer wall of the fixed column 15. The relative sliding of multiple connecting rings 18 on the outer wall of the fixed column 15 effectively disperses the impact force. The spring 19 is arranged between the connecting ring 18 and the fixed column 15. The tension of the spring 19 can effectively absorb the impact force, ensuring that the force generated during the impact is dispersed, reducing the direct collision between the door frame 1 and the door panel 9, reducing the noise generated by the door during use, and effectively reducing the friction and impact between the door panel 9 and the door frame 1, reducing wear, improving the durability of the door, and extending the service life of the door panel 9 and the door frame 1.

[0035] Working principle: In this sliding door, the door frame 1 is used to support the overall structure. There are multiple support platforms 3 on both sides of the inner wall of the door frame 1. The support platforms 3 provide additional support for the top hanging rail 2 to keep it stable. The double-track slide 4 inside the support platform 3 provides a sliding track for the pulley 6. When the door panel 9 is pushed or pulled, the door panel 9 can drive the folding edge 7 at its top and the hanging platform 5 to move synchronously through the connection with the connecting piece 8. The hanging platform 5 can make the pulley 6 slide inside the double-track slide 4 to achieve the effect of a sliding door. The bottom of the hanging platform 5 is fixedly connected There is a folding edge 7, and the distance between the folding edges 7 is similar to the thickness of the door panel 9. Therefore, the distance between the multiple door panels 9 in this sliding door is smaller than that of the traditional sliding door, which helps to reduce the spread of noise. At the same time, the smaller gap can reduce the exchange of indoor and outdoor air, thereby improving the heat insulation performance of the door, and the smaller gap can effectively prevent dust, pollen and other tiny particles from entering the room, improving the indoor air quality, and improving the practicality of this sliding door in many aspects. When the door panel 9 slides inside the slide 10, it will drive the roller 11 on the slide 1 0 rotates internally to improve the sliding smoothness of the door panel 9, and the inner platform 12 inside the door frame 1 can keep the door panel 9 vertical when sliding to the edge, reducing its deviation risk. If a large force is used to push or pull the door panel 9, the door panel 9 will first touch the striker plate 17 when it hits the edge of the door frame 1. After the striker plate 17 is subjected to force, it moves toward the fixed platform 14 and is buffered by the damping rod 16 to reduce the impact force. When the striker plate 17 moves, the multiple sliders 22 on its side wall will slide on the side wall of the striker plate 17, and the sliding of the sliders 22 drives The connecting frame 21 rotates and changes the tilt angle, and the turntable 20 on the other side of the connecting frame 21 can be pulled to drive the connecting ring 18 on the side wall of the turntable 20 to slide on the outer wall of the fixed column 15. The relative sliding of multiple connecting rings 18 will disperse the impact force and further buffer this impact force through the tension of the spring 19, thereby reducing the direct collision between the door frame 1 and the door panel 9, so as to reduce the noise generated by the door during use and reduce the friction and impact between the door panel 9 and the door frame 1, reduce the wear of the door panel 9 and the door frame 1, and extend their service life.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
