Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model is provided: a soundproof wooden single-opening concealed fireproof door, including a door panel 1, a door frame 3 connected to the right side of the inner periphery of the door panel 1 by a hinge 2, a door lock 7 provided on the left side of the front end of the door frame 3, a soundproofing plate 4 and a soundproofing plate 5 provided at the connection between the door frame 3 and the left side of the door panel 1, a soundproofing strip 12 fixedly connected to the bottom end of the door frame 3, and a connecting rod 8 rotatably connected to the top side of the inner periphery of the door panel 1, the other end of the connecting rod 8 being connected to the door frame 3 through a slider 9, a sliding rod 10 and a spring 11;

[0026] Specifically, door panel 1 serves as the supporting frame of the overall structure, providing the installation base for components such as door frame 3 and hinge 2. Hinge 2 enables the rotational connection between door frame 3 and door panel 1, and is the core rotating component for opening and closing door frame 3. Door lock 7 is used to limit the displacement of door frame 3 when it is closed, ensuring the locked state of the door and improving safety. Sound insulation board 1 4 and sound insulation board 2 5 are set at the left connection between door frame 3 and door panel 1, which can block the sound transmission in the gap. Sound insulation strip 12 is fixed at the bottom of door frame 3 to fill the gap between door frame 3 and the ground, further enhancing the sound insulation effect. Connecting rod 8 serves as a connecting component, connecting door panel 1 and door frame 3 to realize the force transmission between the two. Slider 9, slider 10 and spring 11 provide the reset power for door frame 3 to close, ensuring that door frame 3 can automatically return to the closed state.

[0027] Reference Figure 2 , Figure 4 and Figure 6 Door panel 1 is composed of perlite board 101, magnesium oxide board 102, and fire-retardant solid wood board 103. Magnesium oxide board 102 is installed at both ends of the perlite board 101, and fire-retardant solid wood board 103 is installed at one end of each magnesium oxide board 102. Sound insulation board 2 5 is located on the left front end of door panel 1, at the front end of door frame 3. Sound insulation board 1 4 is fixedly connected to the left rear end of door frame 3, at the rear end of door panel 1. A slider 9 is rotatably connected to the other end of connecting rod 8. Block 9 is slidably connected to the inner wall of door frame 3. A sliding rod 10 is slidably connected to the inner wall of slider 9. The sliding rod 10 is fixedly connected to the inner wall of door frame 3. A spring 11 is provided on the outer wall of sliding rod 10. One end of spring 11 is connected to door frame 3, and the other end of spring 11 is connected to slider 9. The top right of the top of connecting rod 8 is rotatably connected to the bottom of door panel 1, and the bottom left of connecting rod 8 is rotatably connected to the top of slider 9. A baffle 6 is fixedly connected to the top of the front end of door panel 1. The baffle 6 is provided on the top of the front end of door frame 3 to block the connecting rod 8.

[0028] Specifically, the three-layer composite structure of door panel 1 has a clear division of labor. Perlite board 101 has excellent heat insulation properties, reducing heat transfer during a fire. Magnesium oxide board 102 has excellent fire resistance and flame retardancy, preventing the spread of fire and enhancing the structural strength of door panel 1. Flame-retardant solid wood board 103 not only has flame-retardant properties but also enhances the appearance and texture of door panel 1, adapting to various decorating styles. Sound insulation board 4 and sound insulation board 5 are staggered, fitting the rear end of door panel 1 and the front end of door frame 3 respectively, effectively blocking sound leakage through the gaps at the connection between door frame 3 and door panel 1, significantly improving sound insulation. To enhance sound insulation, slider 9 and slide rod 10 form a sliding guide structure, ensuring that slider 9 always moves along a fixed trajectory, preventing spring 11 from shifting under force. Spring 11 stores and releases energy through its own elastic deformation, providing a stable restoring force for closing door frame 3. The rotating connection design at both ends of connecting rod 8 can flexibly adapt to the angle changes when door frame 3 is opened, achieving effective force transmission. Baffle 6 covers the connecting rod 8 at the top of door panel 1 and door frame 3, preventing the connecting parts from being exposed, ensuring the door's concealed aesthetics, and preventing foreign objects from getting stuck in connecting rod 8 and affecting its normal operation.

[0029] Working principle: In actual use, when the door frame 3 needs to be opened, the user first twists the door lock 7 on the front left side of the door frame 3. The latch inside the door lock 7 retracts, releasing its limiting and fixing effect on the door frame 3 and the door panel 1. Then, the user pushes the door frame 3 outward, and the door frame 3 will rotate around the hinge 2 on the right side of the inner circumference of the door panel 1 as the center of rotation, thereby opening the door. During this process, the connecting rod 8, which connects the top side of the inner circumference of the door panel 1 and the elastic component of the door frame 3, will rotate synchronously around the end connected to the door panel 1. Since the length of the connecting rod 8 is fixed, when the door frame 3 is opened, it will pull the slider 9 on the inner wall of the door frame 3 through the connecting rod 8, causing the slider 9 to slide away from the spring 11 along the sliding rod 10 fixed on the inner wall of the door frame 3. At the same time, it stretches the spring 11 on the outer wall of the sliding rod 10. The spring 11 will store elastic potential energy at this time. When the user releases the pushing force applied to the door frame 3, the spring 11 will... 1 releases the stored elastic potential energy, applying a pulling force to the slider 9 to contract towards the initial position. Under the action of the pulling force, the slider 9 slides back along the sliding rod 10 and, through its rotational connection with the connecting rod 8, drives the connecting rod 8 to rotate back to its original position around the end of the door panel 1. During the reset process, the connecting rod 8 pushes the door frame 3, causing the door frame 3 to rotate in the opposite direction with the hinge 2 as the center, ultimately achieving automatic closing of the door frame 3. During the closing process, the sound insulation strip 12 at the bottom of the door frame 3 will tightly adhere to the ground, filling the gap between the door frame 3 and the ground. At the same time, the sound insulation plate 4 at the rear end of the door frame 3 and the sound insulation plate 5 at the front end of the door panel 1 will form a misaligned seal, blocking the transmission of sound. The baffle 6 on the top side of the front end of the door panel 1 will always cover the connecting rod 8, maintaining the invisible effect of the door's appearance. The composite structure of the perlite board 101, magnesium oxide board 102, and flame-retardant solid wood board 103 of the door panel 1 can continuously play a fireproof and heat-insulating role, ensuring the safety performance of the door.
