Description

Technical Field

[0001] This utility model relates to the field of wooden doors, and in particular to a novel soundproof wooden door. Background Technology

[0002] Currently, wooden doors used in my country's construction industry are generally divided into solid wood doors and filled composite wood doors. Solid wood doors, being entirely made of wood, consume a large amount of forest resources. In today's increasingly environmentally conscious world, solid wood doors are gradually being replaced by filled composite doors. Solid wood doors are now mostly used in a few high-end buildings. The surface decoration layer of filled composite wood doors is generally made of paper or wood veneer, with the surface layer made of solid wood. The core filling material is generally wood chips, scraps, paper materials, etc. Although this type of door can reduce the manufacturing cost and reduce wood consumption, the core filling material is mostly lightweight, resulting in poor sound insulation.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] like Figures 1 to 8As shown, this embodiment provides a novel soundproof wooden door, including a door body 1 and a soundproof structure 2. A groove 11 is provided at the bottom of the door body 1, and the soundproof structure 2 is installed within the groove 11 at the bottom of the door body 1. The door body 1 includes a central arched structural board 12. Arched structural board is a preferred core material for high-end wooden doors, named for its unique tubular structure resembling the arch of a bridge. As an innovation in core board manufacturing technology, arched structural board has become a major highlight for interior door manufacturers. Arched structural board features fire resistance, sound insulation, and environmental friendliness. Utilizing the principle of an arched bridge, arched structural board is processed using high-tech techniques to create a unique tubular structure from solid wood chips. This structure evenly distributes external forces, preventing deformation. The tubular structure reduces the weight of arched structural board by 60% compared to equivalent solid wood boards. Simultaneously, arched structural board effectively prevents heat diffusion, achieving excellent heat insulation. An arched structural board wooden door is a wooden door that uses arched structural board as its core. The bridge slab 12 is provided with magnesium oxide board 13, damping felt 14, inorganic board 15, and decorative panel 16 on both sides in sequence. The magnesium oxide board 13 is fireproof, waterproof, odorless, non-toxic, non-freezing, non-corrosive, crack-resistant, non-flammable, high-strength, lightweight, easy to construct, and has a long service life. The damping felt 14 is mainly composed of EPDM, a lightweight, ultra-thin, soft material with high tensile strength, providing excellent airborne sound insulation. The decorative panel 16, due to its uniform structure, fine texture, stable performance, impact resistance, and ease of processing, is widely used in domestic furniture, decoration, musical instruments, and packaging. The magnesium oxide board 13, damping felt 14, inorganic board 15, decorative panel 16, and bridge slab 16... The soundproofing structure 2 is made by gluing the soundproofing board 12 together with adhesive. The soundproofing structure 2 includes an outer shell 21, an inner shell 22, a telescopic mechanism 23, and a soundproofing strip 24. The outer shell 21 is fixed in the door slot 11. The telescopic mechanism 23 is installed in the outer shell 21 and pushes the inner shell 22 outward. The bottom of the outer shell 21 has an opening 210. The inner shell 22 is located in the opening 210. The soundproofing strip 24 is installed in the inner shell 22. The soundproofing effect can be achieved by combining multiple layers of boards. In addition, the soundproofing strip 24 is opened downward at the bottom of the wooden door body 1 by the telescopic mechanism 23. The soundproofing strip 24 will press against the ground to improve the soundproofing effect.

[0029] As an optional embodiment, a button structure 25 is installed on the side of the outer shell 21. The button structure 25 is pressed by the door frame during the closing process. The button structure 25 is used to push the telescopic mechanism 23 to extend the inner shell 22 outwards. The telescopic mechanism 23 includes a fixed block 231 and a first sliding block 232. A second sliding block 233 is installed on the inner shell 22. A connecting rod 234 is hinged between the first sliding block 232 and the second sliding block 233. A support rod 235 is installed on the fixed block 231. One end of the support rod 235 is fixed to the fixed block 231, and the other end is hinged to the middle of the connecting rod 234. The fixed block 231 is provided with… A limiting block 2311 is provided, located near the end of the support rod 235. Two telescopic mechanisms 23 are provided, located on both sides of the outer shell 21. A push rod 236 is provided between the first sliding block 232 on one side and the first sliding block 232 on the other side. During use, the button structure 25 presses the first sliding block 232, and the fixing block 231 is fixed inside the outer shell. In this way, the first sliding block 232 opens the support rod 235 and the connecting rod piece 234, so that the second sliding block 233 pushes the inner shell 22 outward. The support rod 235 is restricted by the limiting block 2311. After the support rod 235 swings outward, it will naturally retract, which has an elastic effect.

[0030] As an optional embodiment, the button structure 25 includes a button 251, a screw 252, a spring 253, and an adjusting ring 254. An extension rod 255 is mounted on the adjusting ring 254. The adjusting ring 254 is in a stationary state. The end of the extension rod 255 is fixed on a first sliding block 232. The adjusting ring 254 is sleeved on the screw 252. The length of the screw 252 is adjusted by rotating the screw 252. A top block 256 is provided at the end of the screw 252. The spring 253 is sleeved on the screw 252 and is located between the adjusting ring 254 and the top block 256. The spring 253 pushes the top block 256.

[0031] As an optional embodiment, the inner shell 22 is provided with a first groove 221, and a first limiting edge 222 is provided on both sides of the first groove 221. The second sliding block 233 is inserted into the first groove 221 from the end position. The second sliding block 233 moves within the first groove 221 of the inner shell 22, which is convenient for installation.

[0032] As an optional embodiment, end caps are installed at both ends of the housing 21.

[0033] As an optional embodiment, a second limiting edge 211 is provided inside the housing 21, and the fixing block 231, the first sliding block 232 and the button structure 25 are installed inside the housing 21 from the side. The fixing block 231 is inserted into the housing 21 from the side position and is fixed by screws.

[0034] As an optional embodiment, the inner shell 22 is provided with a second groove 223, and the sound insulation strip 24 includes an mounting edge 241 and a flexible strip 242. The mounting edge 241 is installed in the second groove 223, and the flexible strip 242 has a through hole in the middle and several pressing edges 243 at the bottom. During use, the flexible strip 242 will deform and flatten during the pressing process because it has a through hole. The pressing edges 243 can increase the contact area with the ground and improve the sealing performance.

[0035] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
