Description

Technical Field

[0001] This application relates to the field of soundproof wooden doors, and more particularly to a highly efficient soundproof sealed wooden door. Background Technology

[0002] Prolonged exposure to noisy environments can also impair neurological function. Under the influence of noise, the balance between excitation and inhibition in the cerebral cortex of the brain is easily disrupted, leading to abnormal conditioned reflexes and symptoms such as persistent headaches, neurasthenia, and neurological dysfunction in some individuals. The sound insulation performance of composite wood doors is particularly important when used in bedrooms, studies, and other spaces requiring soundproofing.

[0003] Typical composite wood doors have a simple door structure, resulting in poor sound insulation. When the door is closed, there is a large gap between the door and the frame, which further reduces the sound insulation performance and fails to effectively block out outdoor noise. Utility Model Content

[0004] To improve the sound insulation of wooden doors, this application provides a highly efficient sound-insulating sealed wooden door.

[0005] The technical solution for a highly efficient soundproof sealed wooden door provided in this application is as follows: A highly efficient soundproof sealed wooden door includes a door frame, inside which a door core is provided. The door core includes a core board, and multiple evenly distributed reinforcing rods are provided on both sides of the core board. Glass fiber cotton is also provided between adjacent reinforcing rods, and a single veneer is provided on the side of the reinforcing rod away from the core board.

[0006] By adopting the above technical solution and setting up a multi-layer composite board structure, the sound insulation effect is enhanced. In addition, glass fiber cotton is filled between adjacent reinforcing bars to further improve the sound insulation effect of the wooden door.

[0007] Optionally, the core plate has multiple through holes arranged side by side and evenly distributed, and the length direction of the through holes is perpendicular to the reinforcing rod.

[0008] By adopting the above technical solution, the through holes make the core board hollow, which can disperse external forces and reduce weight. At the same time, the hollow structure allows the core board to play a sound insulation role, further improving the overall performance of the wood board.

[0009] Optionally, multiple grooves are provided on both sides of the reinforcing rod, and the grooves on both sides of the reinforcing rod are staggered.

[0010] By adopting the above technical solution, the grooves on both sides of the reinforcing rod provide different reflective surfaces for sound waves, thereby causing diffuse reflection of sound waves and achieving the effect of noise reduction.

[0011] Optionally, the gantry is provided with sliding grooves on both the upper and lower sides, and a sealing strip is inserted into the sliding groove. The gantry is provided with a drive assembly for driving the sealing strip to slide.

[0012] By adopting the above technical solution, when the wooden door is closed inside the door frame, the drive component drives the sealing strip to protrude out of the groove and abut against the side wall of the door frame, thereby filling the gap between the wooden door and the door frame and reducing the transmission of noise.

[0013] Optionally, the drive assembly includes a support rod disposed within a slide groove, a sealing strip disposed on the support rod, and a plurality of evenly distributed connecting rods disposed below the support rod. A drive rod is slidably connected within the gantry, with one end of the drive rod located within the gantry and the other end extending out of the gantry. The portion of the drive rod located within the gantry has drive grooves corresponding to the connecting rods one-to-one. The bottom of the drive groove is set as an inclined surface, and the end of the connecting rod away from the support rod abuts against the inclined surface. The drive assembly also includes an elastic element connecting the support rod and the drive rod.

[0014] By adopting the above technical solution, when the door frame is closed inside the door frame, the drive rod is squeezed into the door frame, and the bottom of the drive groove on the drive rod squeezes the connecting rod, thereby pushing the support rod upward. As a result, the support rod pushes the sealing strip out of the slide groove. After the door frame is separated from the door frame, the elastic element pushes the drive rod and the support rod back to their original positions, so that the sealing strip returns to the slide groove again, thereby achieving the effect of closing and sealing the wooden door.

[0015] Optionally, the elastic element includes a rebound spring and a compression spring. The end of the drive rod located inside the gantry is connected to the gantry via a rebound spring, while both ends of the support rod are connected to the gantry via compression springs.

[0016] Optionally, a buffer groove is provided on the side of the support rod near the sealing strip, a connecting plate is slidably connected in the buffer groove, the connecting plate is fixedly connected to the sealing strip, and a plurality of evenly distributed buffer springs are provided between the connecting plate and the bottom of the buffer groove.

[0017] By adopting the above technical solution, the buffer groove and buffer spring enable the sealing strip to rise and fall within a certain range. When there is an error in the size of the gap between the door frame and the door frame, the buffer spring can work with the sealing strip to make up the margin, so that the sealing strip can abut against the door frame and avoid excessive pressure on the door frame, which would cause excessive resistance to opening the wooden door.

[0018] Optionally, the sealing strip has multiple evenly distributed countersunk grooves, and countersunk bolts are installed in the countersunk grooves. The ends of the countersunk bolts pass through the sealing sleeve and the connecting plate and are threaded to the support rod.

[0019] By adopting the above technical solution, rotating the countersunk bolt can adjust the maximum rising height of the sealing strip, thereby meeting the adjustment needs of different gap sizes.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The multi-layer composite board structure enhances the sound insulation effect. In addition, glass fiber cotton is filled between adjacent reinforcing bars to further improve the sound insulation effect of the wooden door. 2. When the wooden door is closed within the door frame, the drive assembly causes the sealing strip to protrude from the groove and abut against the side wall of the door frame, thereby filling the gap between the wooden door and the door frame and reducing the transmission of noise.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a highly efficient soundproof sealed wooden door.

[0027] Reference Figure 1 , Figure 2 and Figure 3A highly efficient soundproof sealed wooden door includes a door frame 1, a door core 2 inside the door frame 1, and a core board 21 located in the middle of the core board 21. The core board 21 has multiple evenly distributed and vertically arranged through holes 211. Multiple evenly distributed reinforcing rods 22 are arranged on both sides of the core board 21. The length direction of the reinforcing rods 22 is perpendicular to the length direction of the through holes 211. Multiple grooves 221 are opened on both sides of the reinforcing rods 22. The grooves 221 on both sides of the reinforcing rods 22 are staggered. Glass fiber cotton 23 is filled between adjacent reinforcing rods 22. A single board 24 is arranged on the side of the reinforcing rods 22 away from the core board 21.

[0028] The through-hole 211 makes the core board 21 hollow, which can disperse external forces and reduce weight. At the same time, the hollow structure allows the core board 21 to play a sound insulation role. The glass fiber cotton 23 is filled between the adjacent reinforcing rods 22 to further improve the sound insulation effect of the wooden door. In addition, the grooves 221 on both sides of the reinforcing rods 22 provide different reflection surfaces for sound waves, thereby causing diffuse reflection of sound waves and achieving a sound absorption effect. Thus, a multi-layer composite sound absorption structure is set up to enhance the sound insulation effect.

[0029] Reference Figure 1 and Figure 4 In order to fill the gap between the door frame 1 and the door frame, a sliding groove 11 is provided on both the upper and lower sides of the door frame 1. A sealing strip 3 is inserted into the sliding groove 11. A drive assembly 4 for driving the sealing strip 3 to slide is provided inside the door frame 1.

[0030] When the door frame 1 is closed inside the door frame, the drive assembly 4 drives the sealing strip 3 to protrude out of the groove 11 and abut against the side wall of the door frame, thereby filling the gap between the wooden door and the door frame and blocking the transmission of noise.

[0031] The drive assembly 4 includes a support rod 41 slidably connected in the slide groove 11, a sealing strip 3 installed on the support rod 41, and a plurality of evenly distributed connecting rods 42 fixed below the support rod 41. A drive rod 43 is slidably connected inside the gantry 1. One end of the drive rod 43 is located inside the gantry 1, and the other end passes through the gantry 1. The part of the drive rod 43 located inside the gantry 1 has a drive groove 44 that corresponds one-to-one with the connecting rod 42. The bottom of the drive groove 44 is set as an inclined surface, and the end of the connecting rod 42 away from the support rod 41 abuts against the inclined surface. The drive assembly 4 also includes an elastic element connecting the support rod 41 and the drive rod 43. The elastic element includes a rebound spring 45 and a pressure spring 46. The end of the drive rod 43 located inside the gantry 1 is connected to the gantry 1 through the rebound spring 45, while both ends of the support rod 41 are connected to the gantry 1 through the pressure spring 46.

[0032] When the gantry 1 is closed within the door frame, the drive rod 43 is pressed into the gantry 1. At this time, the return spring 45 is compressed, and the bottom of the drive groove 44 on the drive rod 43 presses against the connecting rod 42, thereby pushing the support rod 41 upward. At the same time, the pressure spring 46 is compressed, thereby the support rod 41 pushes the sealing strip 3 out of the slide groove 11. After the gantry 1 is separated from the door frame, the return spring 45 and the pressure spring 46 push the drive rod 43 and the support rod 41 back to their original positions, so that the sealing strip 3 returns to the slide groove 11 again.

[0033] A buffer groove 411 is provided on the side of the support rod 41 near the sealing strip 3. A connecting plate 412 is slidably connected in the buffer groove 411. The connecting plate 412 is fixedly connected to the sealing strip 3. A plurality of evenly distributed buffer springs 413 are also provided between the connecting plate 412 and the bottom of the buffer groove 411. A plurality of evenly distributed countersunk grooves 414 are provided on the sealing strip 3. Countersunk bolts 415 are provided in the countersunk grooves 414. The end of the countersunk bolt 415 passes through the sealing sleeve and the connecting plate 412 and is threaded to the support rod 41.

[0034] The buffer groove 411 and the buffer spring 413 allow the sealing strip 3 to rise and fall within a certain range. When there is an error in the size of the gap between the door frame and the door frame 1, the buffer spring 413 can work with the sealing strip 3 to make up the margin, so that the sealing strip 3 can abut against the door frame and avoid excessive pressure on the door frame, which would cause excessive resistance to opening the wooden door. In addition, rotating the countersunk bolt 415 can adjust the maximum rising height of the sealing strip 3, thereby making further adjustments.

[0035] The implementation principle of a high-efficiency soundproof sealed wooden door in this application embodiment is as follows: the wooden door rotates and closes inside the door frame, the drive component 4 drives the sealing strip 3 to protrude out of the slide groove 11 and abut against the door frame, thereby filling the gap between the door frame and the wooden door, thereby blocking the transmission of noise. At the same time, the multi-layer structure of the core board 21, reinforcing rod 22, glass fiber cotton 23 and single board 24 inside the wooden door further blocks the transmission of noise.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
