[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] Referring to Figure 1 and Figure 5 , an embodiment provided by the present utility model: A door leaf with good sound insulation effect includes a door frame 1. Strip-shaped openings 2 are provided at both the upper and lower ends of the door frame 1 to provide space for subsequent components. The inner walls of the left and right ends of the door frame 1 are both slidably connected with door leaf panels 3, enabling the door leaf panels 3 to slide horizontally. A protection plate 16 is fixedly connected to the front side of the door leaf panel 3. The material of the protection plate 16 is synthetic resin, which has a certain impact resistance. A sound insulation layer 301 is fixedly connected inside the door leaf panel 3. The material of the sound insulation layer 301 is PC board, and the PC board has good sound insulation performance. A fire protection layer 302 is fixedly connected inside the sound insulation layer 301. The material of the fire protection layer 302 is gypsum board, and the gypsum board is a non-combustible material, enhancing the safety of the door leaf. A tempered layer 303 is fixedly connected to the inner wall of the fire protection layer 302. The material of the tempered layer 303 is tempered glass, providing additional strengthening and protection effects.

[0042] Referring to Figures 1 to 3, strip plates 4 are fixedly connected to both the upper and lower sides of the door leaf plate 3 to limit the sliding of the door leaf plate 3 and prevent the door leaf plate 3 from shifting during sliding. Convex openings 5 are provided at the adjacent ends of the two door leaf plates 3 to limit the movement of subsequent components. Sealing components for sealing the door leaf plate 3 are slidably connected to the adjacent ends of the two door leaf plates 3. Limiting plates 8 are fixedly connected to the opposite sides of the two sealing components to limit the sealing components. The outer part of the limiting plate 8 is slidably connected to the inner wall of the door leaf plate 3, enabling the limiting plate 8 to slide horizontally. The sealing component includes a connecting plate 7, and the outer part of the connecting plate 7 is slidably connected to the inner wall of the door leaf plate 3, enabling the connecting plate 7 to slide horizontally. Sealing plates 6 are fixedly connected to the adjacent sides of the two connecting plates 7 to improve the sealing between the two door leaf plates 3. Limiting plates 8 are fixedly connected to the opposite sides of the two connecting plates 7 to provide a supporting force to the connecting plate 7 and prevent the sealing plate 6 from slipping.

[0043] Refer to Figure 3 , Figure 4 and Figure 6 , two triangular blocks 9 are fixedly connected to the opposite sides of the two limiting plates 8 to provide a supporting force to the triangular blocks 9. A T-shaped opening 10 is provided inside the triangular block 9 to limit the movement of subsequent components. A sliding component for pushing subsequent components to slide is slidably connected to the inner wall of the triangular block 9. The sliding component includes a sliding column 11, and the outer part of the sliding column 11 is slidably connected to the inner wall of the triangular block 9, making the force received by the sliding column 11 inclined. Connecting columns 12 are fixedly connected to the opposite sides of every two sliding columns 11 to provide a supporting force to the sliding column 11 and serve as a medium for force transmission. Connecting plates 13 are fixedly connected to the opposite sides of every two sliding components. A fixed rod 14 is fixedly connected to the inner wall of the door leaf plate 3 to provide a supporting force to the fixed rod 14. Springs 15 are sleeved on both the upper and lower ends of the fixed rod 14 to limit the springs 15, enabling the springs 15 to receive uniform force. The opposite sides of every two connecting plates 13 are respectively fixedly connected to the adjacent ends of every two springs 15 to provide a restoring elastic force to the connecting plates 13. Handles 17 are fixedly connected to the adjacent front ends of the two door leaf plates 3 to facilitate holding the handles 17 to pull the door leaf plate 3 to slide. Vertical plates 18 are fixedly connected to the inner walls of the left and right ends of the door frame 1 to limit the vertical plates 18 and the movable door leaf plate 3, and the door leaf plate 3 slides along the vertical plate 18.

[0044] Working principle: By holding the two handles 17 and applying a pulling force, the handles 17 can drive the door leaf panels 3 to slide. At this time, the two door leaf panels 3 will respectively drive the two strip-shaped plates 4 to slide towards the adjacent side. When the two door leaf panels 3 touch each other, the two sealing plates 6 will come into contact first. At this time, the two sealing plates 6 will respectively receive mutual reaction forces to push the connecting plate 7 to slide. Then, the two connecting plates 7 will respectively push a limiting plate 8 to slide. During the sliding process of the limiting plate 8, the two triangular blocks 9 will be driven to slide respectively. During the sliding process of the limiting plate 8, and by using the opening of the T-shaped opening 10, the internal structure of the triangular block 9 is made inclined. At this time, when the triangular block 9 abuts against the sliding column 11 and pushes the sliding column 11 to slide, as the triangular block 9 continuously slides towards the sliding column 11, the sliding column 11 will slide on both sides, thereby pushing the connecting column 12 to slide, and then pushing the connecting plate 13 to slide and compress the spring 15, so that the spring 15 can store elastic potential energy. Then, through the mutual contact and extrusion of the sealing plates 6, the force is transmitted to the spring 15 by the mechanical structure, and the spring 15 will transmit the restored force to the sealing plates 6 by the mechanical structure, making the two sealing plates 6 and between the sealing plate 6 and the door leaf panel 3 fit more closely, thereby improving the sealing performance of the device, reducing the transmission of sound, improving the sound insulation effect of the door leaf panel 3, and the contact between the two sealing plates 6 can reduce the collision and friction between the two door leaf panels 3, thereby extending the service life of the door leaf panel 3;

[0045] The protective plate 16 welded to the door leaf panel 3 is made of synthetic resin, which is not only light but also has good impact resistance. In daily life, the protective plate 16, as the first line of defense of the door leaf, can effectively resist external force impacts, such as damage caused by accidental impacts or bad weather, thereby protecting the internal structure of the door leaf from being damaged. The sound insulation layer 301 inside the door leaf panel 3 is made of PC board. Due to its high density and material properties, it can achieve good sound insulation effects. The main function of the sound insulation layer 301 is to reduce the ability of sound to pass through the door leaf. When sound waves hit the sound insulation layer 301, the structure and material of the PC board can absorb and block part of the sound waves, effectively reducing the transmission of noise and providing a quiet living or working environment. The fireproof layer 302 welded to the sound insulation layer 301 uses gypsum board as the material. As a non-combustible material, the core function of the gypsum board is to increase the fire resistance time of the door leaf in case of a fire and delay the spread of the fire. This design not only improves the safety of the door leaf but also provides a valuable time window for personnel evacuation and fire control. Then, the toughened layer 303 welded to the fireproof layer 302 is made of toughened glass, which has high strength and thermal stability and can further enhance the protection performance of the door leaf. In the face of extreme temperature changes or strong impacts, the toughened layer 303 can maintain the integrity of the structure, prevent debris from splashing and causing harm, and at the same time cooperate with the fireproof layer 302 to provide a higher level of safety guarantee. Therefore, with mutual cooperation, the flexibility and safety of the door leaf panel 3 are improved.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
