[0002] Wooden doors, that is, wooden doors, can be divided into many categories according to material, craftsmanship and use; the core of solid wood composite doors is mostly made of pine, fir or imported filling materials, etc., and the density board and solid wood veneer are pasted on the outside, and are made after high temperature hot pressing, and the edges are sealed with solid wood lines; solid wood doors are made of natural logs taken from the forest as the core, and are dried, and then scientifically processed through cutting, planing, mortising, drilling, high-speed milling and other processes.
[0003] Chinese patent publication number CN221032233U discloses a heat-insulating and sound-insulating composite wooden door, which relates to the technical field of composite doors, including a wooden door body, a supporting layer, a sound-insulating layer and a heat-insulating layer. Side sealing plates are arranged on both sides of the wooden door body, and top and bottom sealing plates are arranged on the top and bottom of the wooden door body. The sound-insulating layer in a vacuum state is conducive to blocking the propagation of sound inside the sound-insulating layer. At the same time, the hollow structure greatly improves the sound insulation effect of the wooden door while reducing the weight.
[0004] The above patent mainly blocks the propagation of sound inside the sound insulation layer through the vacuum state sound insulation layer, and at the same time greatly improves the sound insulation effect of the wooden door while reducing the weight through the hollow structure. Aerogel helps to make the wooden door have better thermal insulation performance.
[0005] However, the vacuum sound insulation layer is expensive and inconvenient to assemble. In addition, since wooden doors have good toughness, after long-term use, the wooden doors are prone to concave or even cracking due to air pressure differences, which can easily cause large gaps between the door body and the door frame, thereby reducing the sound insulation effect of the wooden doors. Utility Model Content
[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a wooden door structure with efficient sound insulation effect, so as to solve the technical problems mentioned in the above background technology.

[0008] A wooden door structure with high-efficiency sound insulation effect, comprising an outer frame, wherein a wooden door body is hingedly connected to the inner part of the outer frame;
[0009] The wooden door body comprises a first door panel and a second door panel, the edges of the first door panel and the second door panel are commonly connected with a closed frame, and a plurality of support columns are arranged between the first door panel and the second door panel;

[0013] Furthermore, the first door panel and the second door panel are both concave structures, and the thickness of the first door panel and the second door panel is equal to the thickness of the extension rod.
[0014] Furthermore, the positioning connecting rod cooperates with the pipe opening of the positioning tube, and the thickness of the supporting crossbeam is equal to that of the supporting column.
[0015] Furthermore, the support column includes two conical cones, the top surfaces of the two conical cones are each provided with a mounting hole, and the interiors of the two mounting holes are commonly connected to a piston rod.
[0016] Furthermore, the ends of the side inclined plate and the top inclined plate are connected to each other.
[0017] Furthermore, the direction of the slope of the inner frame wall of the outer frame is the same as the direction of the slope of the side slope plate and the top slope plate.
[0018] In summary, the present invention includes at least one of the following beneficial technical effects:
[0019] 1. A wooden door structure with high-efficiency sound insulation effect. When external sound is transmitted to the wooden door body through the air, it first contacts the second door panel, and then is transmitted to the gap between the first door panel and the second door panel through the second door panel, and then is transmitted to the inside of the first door panel.

[0021] 3. This is a wooden door structure with high efficient sound insulation effect. After the wooden door body and the door frame are closed, the side inclined plates and the top inclined plates are fitted with the inner frame surface of the outer frame, so that the door gap forms an oblique door gap, and when the sound is conducted, the oblique gap deflects the sound propagation path, and the sound no longer propagates in a straight line, but diffuses along the direction of the oblique gap.

DETAILED DESCRIPTION
[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0030] Example:
[0031] Reference Figure 1-Figure 5The utility model discloses a wooden door structure with high-efficiency sound insulation effect, comprising an outer frame 1, wherein a wooden door body 2 is hingedly connected to the inner part of the outer frame 1;
[0032] The wooden door body 2 includes a first door panel 21 and a second door panel 22. The edges of the first door panel 21 and the second door panel 22 are connected to a closed frame 23. A plurality of support columns 24 are arranged between the first door panel 21 and the second door panel 22.
[0033] The closed frame 23 includes two sets of fixed frames and two sets of end frames;
[0034] The fixed frame includes a support column 231, an extension rod 232 is fixedly provided on one side of the support column 231, a side inclined plate 233 is provided on one end of the extension rod 232 away from the support column 231, and a positioning tube 234 is provided inside the support column 231;
[0035] The end frame includes a top inclined plate 235 , a supporting crossbeam 236 is disposed at the bottom end of the top inclined plate 235 , and positioning connecting rods 237 are disposed at both sides of the bottom end of the top inclined plate 235 .
[0036] In this embodiment, during assembly, the first door panel 21 and the second door panel 22 are separated from each other to the sides, so that the support column 24 is extended, and before the first door panel 21 and the second door panel 22 are buckled together, the two fixing frames are respectively installed at the two ends of the gap between the first door panel 21 and the second door panel 22, and the first door panel 21 and the second door panel 22 are buckled together to achieve the effect of connecting the first door panel 21 and the second door panel 22 to each other. At the same time, after the first door panel 21, the second door panel 22 and the fixing frame are connected to each other, the end frame is inserted into the gap between the first door panel 21 and the second door panel 22. , thereby achieving the effect of the closed frame 23, the first door panel 21 and the second door panel 22 together forming the wooden door body 2, and then when the external sound is transmitted to the wooden door body 2 through the air, it first contacts with the second door panel 22, and then is transmitted to the gap between the first door panel 21 and the second door panel 22 through the second door panel 22, and then is transmitted to the inside of the first door panel 21. Since part of the sound will be rebounded when it is transmitted from one medium to another, when the sound continuously changes the transmission medium, the size of the sound can be effectively reduced, thereby achieving the purpose of sound insulation;
[0037] Specifically, as shown in the figure and the figure, when the first door panel 21 and the second door panel 22 are buckled together, the protrusions on both sides of the first door panel 21 and the second door panel 22 are inserted into the gap between the side inclined plate 233 and the supporting column 231, so that the first door panel 21 and the second door panel 22 are relatively connected and the first door panel 21 and the second door panel 22 are positioned at the same time, and after the first door panel 21, the second door panel 22 and the fixed frame are connected to each other, the supporting crossbeam 236 at the bottom end of the top inclined plate 235 is inserted into the gap at the top of the first door panel 21 and the second door panel 22, and the position of the positioning link 237 corresponds to the position of the positioning tube 234, and then the top inclined plate 235 is continued to be pressed down to insert the positioning tube 234 into the interior of the positioning tube 234, and the supporting crossbeam 236 and the supporting column 231 together form a complete rectangular frame for supporting the first door panel 21 and the second door panel 22;
[0038] The first door panel 21, the fixed frame, the closed frame 23 and the second door panel 22 are all provided with rubber pads at their contact points, so as to isolate the various parts from each other and make the plug-in parts interference-connected, thereby improving the stability of the wooden door body 2 and isolating the various parts of the wooden door body. The sound will pass through the rubber pads during the propagation process, so that the medium through which the sound passes when passing through the wooden door can be effectively improved, and then the purpose of improving the sound insulation effect can be achieved by replacing the propagation medium.
[0039] When the supporting columns 231 and the supporting crossbeams 236 are connected to form a rectangular frame, the corners of the side inclined plates 233 and the top inclined plates are connected to form a rectangular frame, and the inclined surfaces of the side inclined plates 233 and the top inclined plates together form a trapezoidal pile.
[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, both the first door panel 21 and the second door panel 22 are concave structures, and the thickness of the first door panel 21 and the second door panel 22 is equal to the thickness of the extension rod 232 .
[0041] In this embodiment, since the first door panel 21 and the second door panel 22 are both concave structures, the raised corners on both sides of the first door panel 21 and the second door panel 22 can be inserted into the position between the support column 231 and the side inclined plate 233, thereby achieving the effect of positioning the first door panel 21 and the second door panel 22. At the same time, since the thickness of the extension rod 232 is equal to the thickness of the first door panel 21 and the second door panel 22, and the extension rod 232 is used to connect the support column 231 and the side inclined plate 233, when the first door panel 21 and the second door panel 22 are inserted into the gap between the support column 231 and the side inclined plate 233, they can be well in contact with the side walls of the support column 231 and the side inclined plate 233 to improve the stability of the first door panel 21 and the second door panel 22.
[0042] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the positioning link 237 cooperates with the pipe opening of the positioning tube 234 , and the thickness of the supporting crossbeam 236 is equal to that of the supporting column 231 .
[0043] In this embodiment, since the thickness of the supporting beam 236 and the supporting column 231 are equal, when the supporting column 231 and the supporting beam 236 are connected to each other to form a frame, the planes on both sides of the supporting column 231 and the supporting beam 236 are parallel to each other, and when the first door panel 21 and the second door panel 22 are connected to each other, the gap between the first door panel 21 and the second door panel 22 is not connected to the outside world. When the external sound is transmitted to the wooden door body 2 through the air, it first contacts the second door panel 22, and then is transmitted to the gap between the first door panel 21 and the second door panel 22 through the second door panel 22. When it is transmitted to the inside of the first door panel 21, part of the sound will be bounced back when it is transmitted from one medium to another. Therefore, when the sound continuously changes the propagation medium, the size of the sound can be effectively reduced, thereby achieving the purpose of sound insulation.
[0044] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the support column 24 includes two conical truncated cones 241 , and the top surfaces of the two conical truncated cones 241 are each provided with a mounting hole 242 , and the interiors of the two mounting holes 242 are commonly connected to a piston rod 243 .
[0045] In this embodiment, the piston rod 243 is installed by setting two conical cones 241 and mounting holes 242. The two conical cones 241 are respectively connected to the first door panel 21 and the second door panel 22. Since a plurality of support columns 24 are provided, the first door panel 21 and the second door panel 22 can be supported at all positions. Therefore, the stability of the first door panel 21 and the second door panel 22 can be well improved, so that the piston rod 243 is inserted into the interior of the mounting hole 242, and the mounting hole 242 forms a closed space. In normal conditions, the length of the support column 24 is less than the length of the support beam 236 and the support column. The thickness is 231, so when the first door panel 21 and the second door panel 22 are separated from each other, the support column 24 will stretch outward, and when the fixed frame is installed on both sides of the first door panel 21 and the second door panel 22, the support column 24 will shrink to achieve the purpose of clamping the fixed frame through the first door panel 21 and the second door panel 22. At the same time, since the first door panel 21, the second door panel 22, the conical cone 241 and the piston rod 243 are made of different materials, the sound can be further attenuated when it is propagated through the support column, thereby effectively avoiding the problem of sound propagation from the connecting structure inside the wooden door body 2.
[0046] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the ends of the side inclined plate 233 and the top inclined plate 235 are connected to each other.
[0047] In this embodiment, when the supporting columns 231 and the supporting beams 236 are interconnected to form a rectangular frame, the corners of the side inclined plates 233 and the top inclined plates 235 are interconnected to form a rectangular frame, so that the inclined surfaces of the side inclined plates 233 and the top inclined plates 235 can together form the shape of a trapezoidal platform.
[0048] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the slope direction of the inner frame wall of the outer frame 1 is the same as the slope direction of the side slope plate 233 and the top slope plate 235 .
[0049] In this embodiment, since the inclined surfaces of the outer frame 1, the side inclined plate 233 and the top inclined plate 235 have the same direction, after the wooden door body and the door frame are closed, the side inclined plate 233 and the top inclined plate 235 fit with the inner frame surface of the outer frame 1, so that the door gap forms an oblique door gap, which can effectively reduce the light transmittance of the wooden door gap. When the sound is transmitted, the oblique gap causes the sound propagation path to be deflected, and the sound no longer propagates in a straight line, but will diffuse along the direction of the oblique gap. Therefore, the sound will be more easily diffracted, thereby achieving the purpose of reducing the volume.
[0050] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
