Description

Technical Field

[0001] The utility model belongs to the field of sound insulation and noise reduction doors, and in particular relates to a sound insulation door with a linkage sound barrier for a quiet room. Background Art

[0002] Within the building envelope, doors and windows are weak links in sound insulation. Doors are the least soundproof components of walls because they are generally lighter than walls. Their gaps act as a pathway for airborne sound, and their smaller surface area causes low-frequency resonances to occur within critical ranges of the audio spectrum. Therefore, careful sound insulation is essential. A door's sound insulation performance depends on the sound insulation capacity of the door leaf itself (such as its weight and composition) and the tightness of the door gap. While increasing the weight and thickness of a door can improve its sound insulation, it can also make it more difficult to open, and the hinges can easily tilt downward, widening the gap and compromising its effectiveness. Single-layer soundproof doors, even with complex multi-layer composite doors, often offer limited sound insulation. They often fail to meet the sound insulation requirements of buildings with specialized soundproofing requirements, such as quiet testing rooms, recording studios, broadcasting studios, and technical rooms in hospital otology departments. In order to further improve the sound insulation performance of doors, especially doors that need to be opened and closed frequently, an effective method is to set up double doors and place strong sound-absorbing materials between the double doors to absorb as much external noise as possible that has been transmitted to the first door. This constitutes the so-called "sound gate", also known as "sound lock". This measure can often make the total sound insulation capacity reach the sum of the sound insulation of the two doors, just like a double wall, and the air layer between the two doors obtains a large additional sound insulation.

[0003] However, in actual use, two doors are often designed with the outer door opening outward and the inner door opening inward, such as in CN217681454U. This requires sufficient space on both sides of the doorway to open the door leaf, which is inconvenient in some compact environments. To save space on one side of the door, if the two doors open in the same direction, the distance between the two doors is generally about 60mm. When the first door is opened towards the second door, the corner of the first door will press against the second door with only a crack. If the door is pushed hard for a long time, it will damage the second door and cause inconvenience to the user. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes that two doors can be opened in a linked manner, thereby providing a silent room linked sound barrier soundproof door.

[0005] The purpose of the utility model is achieved in the following way: a silent room linked sound barrier soundproof door, comprising a first soundproof door 1 and a second soundproof door 2 installed at the same doorway, the first soundproof door 1 and the second soundproof door 2 rotating and opening in the same direction, a connecting member 3 is provided between the first soundproof door 1 and the second soundproof door 2, so that when one of the soundproof doors moves, the other soundproof door is carried along with the movement.

[0006] Furthermore, the connecting member 3 includes a linear guide rail 31, which is fixedly connected to the first sound insulation door 1. The linear guide rail 31 is arranged horizontally, and a slider 32 is slidably arranged on the linear guide rail 31. The slider 32 is fixedly connected to the first connecting arm 33. The first connecting arm 33 is rotatably connected to one end of the second connecting arm 35 through a rotating member 34. The rotating member 34 allows the first connecting arm 33 and the second connecting arm 35 to rotate horizontally. The other end of the second connecting arm 35 is fixedly connected to the mounting plate 36, and the mounting plate 36 is fixedly connected to the second sound insulation door 2.

[0007] As a solution, the rotating member 34 is a vertical rotating shaft.

[0008] As a solution, the rotating member 34 is a universal joint.

[0009] Furthermore, the width difference between the first soundproof door 1 and the second soundproof door 2 is x, the distance between the first soundproof door 1 and the second soundproof door 2 in the closed state is y, and |x|≥y.

[0010] Compared with the prior art, the present invention provides a connecting piece between the two soundproof doors, so that when one door is opened, the other door is also opened in conjunction, reducing the inconvenience of the door opener. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a structural diagram of the connector;

[0013] Figure 3 This is a schematic diagram of the working status of the linked sound barrier and soundproof door from above.

[0014] Among them, the first sound insulation door 1, the second sound insulation door 2, the connecting member 3, the linear guide rail 31, the slider 32, the first connecting arm 33, the rotating member 34, the second connecting arm 35, and the mounting plate 36. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] In the present invention, unless otherwise expressly specified and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0017] As attached Figure 1 As shown, a silent room linked sound barrier soundproof door includes a first soundproof door 1 and a second soundproof door 2 installed at the same doorway. The first soundproof door 1 and the second soundproof door 2 rotate and open in the same direction. A connecting member 3 is provided between the first soundproof door 1 and the second soundproof door 2 so that when one soundproof door moves, the other soundproof door is moved along with it.

[0018] The double-channel soundproof door itself belongs to the mature existing technology, and the present utility model does not modify or limit the structure of the door itself.

[0019] It should be noted that, since the first soundproof door 1 and the second soundproof door 2 are opened in linkage, the use of a traditional lock tongue structure for the soundproof door will result in the lock tongue mechanism of one of the doors being unable to be unlocked due to the user's inability to reach it, making both doors unable to be opened. Therefore, considering that the soundproof door itself does not need to have an anti-theft function but only requires a sound insulation function, the traditional lock tongue structure is not used, and a one-bump unlocking or a magnetic attraction structure is preferably used. The one-bump unlocking is a mature existing technology and will not be described here. The magnetic attraction structure refers to magnets that attract each other on the side of the door and the door frame, which are used to maintain the position of the door when it is closed, which is also a mature existing technology.

[0020] As attached Figure 2As shown, the connecting member 3 includes a linear guide rail 31, which is fixedly connected to the first sound insulation door 1, and the linear guide rail 31 is arranged horizontally. A slider 32 is slidably arranged on the linear guide rail 31, and the slider 32 is fixedly connected to the first connecting arm 33. The first connecting arm 33 is rotatably connected to one end of the second connecting arm 35 through a rotating member 34. The rotating member 34 allows the first connecting arm 33 and the second connecting arm 35 to rotate horizontally. The other end of the second connecting arm 35 is fixedly connected to the mounting plate 36, and the mounting plate 36 is fixedly connected to the second sound insulation door 2.

[0021] Furthermore, the rotating member 34 is a vertical rotating shaft, which can achieve the effect of allowing the first connecting arm 33 and the second connecting arm 35 to rotate in the horizontal direction, so that the connecting member 3 does not cause interference in the working state.

[0022] Furthermore, the rotating member 34 is a universal joint. The universal joint is a prior art and can satisfy the effect of enabling the first connecting arm 33 and the second connecting arm 35 to rotate in the horizontal direction and the vertical direction. The purpose is that after the sound insulation door is used for a long time, due to aging of hardware and other reasons, the door body may have a certain degree of falling and deformation. The deformation amount of the first sound insulation door 1 and the second sound insulation door 2 may not be the same. The universal joint is used to compensate for a certain difference in vertical deformation amount.

[0023] As attached Figure 3 As shown, the width difference between the first soundproof door 1 and the second soundproof door 2 is x, and the distance between the first soundproof door 1 and the second soundproof door 2 in the closed state is y, |x|≥y, where y is the distance between the same-direction door surfaces of the first soundproof door 1 and the second soundproof door 2, as indicated in the figure; the purpose of this setting is that if the widths of the first soundproof door 1 and the second soundproof door 2 are equal, the position of the outer door will interfere with the inner door, and it will not be able to be fully opened, causing inconvenience in entering and exiting. When |x|=y, it is the most preferred value. The distance between the first soundproof door 1 and the second soundproof door 2 changes little throughout the door opening process, and the door can be fully opened to leave a passage for people to pass through. When |x|>y, the door can also be fully opened, but the degree of change in the distance between the first soundproof door 1 and the second soundproof door 2 during the opening process increases as the difference between |x| and y increases, which is generally not as good as the preferred value.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
