Description

Technical Field

[0001] The invention relates to the technical field of sound barriers, and in particular to a banquet hall sound barrier structure and a construction process thereof. Background Art

[0002] In the prior art, for places such as banquet halls, when meetings are required, the requirements for quietness are high. Therefore, some high-end banquet halls are equipped with sound barrier structures. The function of the sound barrier structure is to effectively isolate external noise. The structure is similar to a door, but it has obvious improvement in sound insulation effect compared with household doors. Sound insulation materials are provided inside the door panels for sound insulation. The existing sound barrier opening method mainly uses hinges, but the hinge opening method makes it inevitable that there is a certain gap between the door panel and the door frame, so as to avoid the door panel from getting stuck with the door frame when it is opened. After long-term use, the lack of oil in the hinge will cause noise when opening or closing, which is not conducive to ensuring the sound insulation effect. After searching, the Chinese patent application number 202022325159.4 discloses a high-efficiency soundproof door sealed sound gate structure, one side of the door and window frame is fixed to the wall structure, and a holder is provided on the other side of the wall structure, and a accommodating cavity is provided in the door and window frame, and the accommodating cavity is filled with glass wool. The other side of the door and window frame is in contact with the door and window leaf, and at least two magnetic sealing strips are arranged from the inside to the outside in the gap between the door and window frame and the door and window leaf, and micro sound-absorbing material is filled between the two adjacent magnetic sealing strips.

[0012] On the basis of the above-mentioned solution: a touch switch is fixed on the wall surface by embedding, and the touch switch and the electric telescopic rod are electrically connected.

[0013] Based on the above solution, preferably: a ratchet wheel matching with the ratchet teeth is fixed to the bottom of the turntable by a pin.

[0014] A construction process for a banquet hall sound barrier structure comprises the following steps: S1: Install the door frame on the wall surface by embedding; S2: After the box body and the top of the door frame are fixedly connected, the top of the sound damper plate and the bottom of the rotating column are installed and fixed; S3: Install the touch switch on the wall surface by embedding, and electrically connect the touch switch and the electric telescopic rod through a wire; S4: After opening the box panel, add a certain amount of lubricating oil into the oil pot, close the box panel to complete the installation of the entire sound barrier.

[0015] The beneficial effects of the present invention are: 1.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Embodiment 1: A banquet hall sound barrier structure, such as Figures 1 to 9 As shown, it includes a door frame 11 installed on a wall 1, a box body 3 is fixed to the top outer wall of the door frame 11 by bolts, and a box plate 6 is rotatably connected to one end of the box body 3, a cushion block 9 is fixed to the bottom inner wall of the box body 3 by bolts, and a driving rod 8 is slidably connected to the inner wall of a through hole opened on the surface of the cushion block 9, and a connecting block 18 is fixed to one end of the driving rod 8 by bolts, and a rotating column 24 is rotatably connected to the inner wall of the through hole opened on the surface of the connecting block 18, and a sound damper plate 2 is fixed to the bottom of the rotating column 24 by bolts, and a gear 25 is connected to the circumferential outer wall of the rotating column 24 by a key, and a receiving shell 26 is fixed to the top outer wall of the connecting block 18 by a pin, and the circumferential inner wall of the receiving shell 26 and the circumferential outer wall of the rotating column 24 are fixed to the same coil spring 27 by pins; A fixing rod 28 is fixed to the inner wall of the bottom of the box body 3 by a pin, and a rack 12 adapted to the gear 25 is fixed to one end of the fixing rod 28 by a pin, and a sound insulation sealing strip 4 is fixed to the outer wall of the sound damper plate 2 by a sleeve connection; In the initial stage, the coil spring 27 is used to keep the rotating column 24 in a stationary state relative to the connecting block 18, so that the sound damper 2 and the wall 1 are in parallel positions in the stationary state. When the sound damper 2 is needed to block the door frame 11 to achieve sound insulation, the driving rod 8 is slid along the cushion block 9 to make the sound damper 2 gradually approach the inner surface of the door frame 11. When the sound damper 2 moves to the inner surface of the door frame 11, the sound insulation sealing strip 4 can be provided to close a small gap between the sound damper 2 and the door frame 11, thereby effectively improving the sound insulation effect and avoiding the sound insulation effect being deteriorated due to the gap between the sound damper 2 and the door frame 11. When the sound gate 2 needs to be opened, the sound gate 2 is moved in the direction away from the door frame 11 by moving the driving rod 8 in the opposite direction. During this process, when the gear 25 moves to contact the rack 12, the rack 12 is used to make the gear 25 drive the sound gate 2 to rotate, so that when the sound gate 2 is separated from the door frame 11, it can be rotated and opened to facilitate people to enter and exit. By adjusting the moving distance of the connecting block 18, the opening angle of the sound gate 2 can be adjusted. When the sound gate 2 needs to be closed again, after the gear 25 is separated from the surface of the rack 12, the sound gate 2 is quickly restored to its initial position by the rebound force of the coil spring 27, so that the sound gate 2 can be opened or closed again.

[0029] Further, the outer wall of one side of the connecting block 18 is fixed with a frame 13 by bolts, and a receiving plate 30 is fixed with a pin at one end of the frame 13, and an oil groove 31 is provided on the surface of the receiving plate 30, and a liquid sensor is provided on the inner surface of the oil groove 31, and a regulating valve 14 is connected to the outer wall of the circumference of the receiving plate 30 by threads, and a lubricating hose 7 is fixed to one end of the regulating valve 14 by insertion, and a frame 29 is fixed with a bolt on the outer wall of one side of the connecting block 18, and a turntable 33 is rotatably connected to the inner wall of the through hole provided on the surface of the frame 29 by a damping shaft, and an oil pot 10 is fixed to the outer wall of the top of the turntable 33 by a pin, and a filling pipe is integrally formed on the top of the oil pot 10, and an injection pipe 32 adapted to the inner diameter of the oil groove 31 is welded to the outer wall of the bottom of the oil pot 10; The oil pot 10 can be provided to store lubricating oil. When the driving rod 8 slides along the cushion block 9 for a long time and the rotating column 24 rotates along the connecting block 18 for a long time, the contact position between the two will cause friction due to lack of lubricating oil and produce sound, which will affect the sound insulation effect. The oil pot 10 and the injection pipe 32 can be rotated along the top of the accommodating plate 30. When the bottom of the injection pipe 32 and the oil groove 31 are aligned, the lubricating oil stored in the oil pot 10 can be introduced into the oil groove 31 through the injection pipe 32. The lubricating oil entering the oil groove 31 can be pumped out by the regulating valve 14 and injected into the cushion block 9 and the accommodating shell 26 respectively through the lubricating hose 7, so that the outer wall of the driving rod 8 and the gap between the rotating column 24 and the connecting block 18 can be lubricated, thereby reducing the noise problem caused by friction between the two.

[0030] Furthermore, the outer circumferential wall of the rotating column 24 is fixed with an intermediate rod 21 by a pin, and one end of the intermediate rod 21 is fixed with a square block 22 by a pin, the inner wall of the through hole opened on the surface of the square block 22 is slidably connected with a T-shaped rod 19, and a spring 23 is fixed between the inner wall of one side of the T-shaped rod 19 and the outer wall of one side of the square block 22 by a pin, and one end of the T-shaped rod 19 is fixed with a ratchet 20 by a pin, and the bottom of the rotating disk 33 is fixed with a ratchet 34 adapted to the ratchet 20 by a pin; By providing the ratchet 20, when the rack 12 drives the gear 25 to rotate, the ratchet 20 can drive the ratchet 34 to rotate a certain angle. During the rotation of the ratchet 34, the injection pipe 32 at the bottom of the oil pot 10 will also rotate a certain angle relative to the top of the accommodating plate 30. When the ratchet 20 rotates in the opposite direction, the characteristics of the ratchet mechanism are utilized to make the ratchet 20 bounce along the circumferential outer wall of the ratchet 34. Since the turntable 33 and the frame 29 are connected by a damping shaft, the ratchet 34 has a certain damping relative to the frame 29. Therefore, during the process of the ratchet 20 bouncing along the circumferential outer wall of the ratchet 34, the ratchet 34 can maintain Maintain stability, thereby preventing the injection tube 32 from moving relative to the surface of the accommodating plate 30. When the injection tube 32 is finally rotated to dock with the oil groove 31, the lubricating oil stored in the oil pot 10 can enter the oil groove 31 through the injection tube 32. When the lubricating oil enters the oil groove 31, the liquid sensor installed in the oil groove 31 senses the presence of the lubricating oil and can feed back a signal to the control center to start the regulating valve 14 to achieve lubrication. By setting the oil pot 10 and the injection tube 32 to be rotatable, it is possible to effectively prevent the lubricating oil in the oil pot 10 from being frequently introduced into the oil groove 31 through the injection tube 32, resulting in waste of lubricating oil, thereby saving the use of lubricating oil.

[0031] Furthermore, a vertical plate 17 is fixed to the inner wall of the bottom of the box body 3 by bolts, and an electric telescopic rod 16 is fixed to the outer wall of one side of the vertical plate 17 by bolts, and the output end of the electric telescopic rod 16 is fixed to a vertical plate 15 by a pin, and the vertical plate 15 is fixedly connected to one end of the driving rod 8; By providing an electric telescopic rod 16, the vertical plate 15 and the driving rod 8 can be driven to move along the cushion block 9, thereby controlling the opening or closing of the sound damper plate 2.

[0032] Furthermore, a touch switch 5 is fixed on the surface of the wall 1 by embedding, and the touch switch 5 is electrically connected to the electric telescopic rod 16; The touch switch 5 is provided so that when the surface thereof is touched, the electric telescopic rod 16 is activated to open the sound damper 2 .

[0033] When the present embodiment is in use, when it is necessary to open the sound damper 2, the user first presses the touch switch 5 with his hand, and the touch switch 5 inputs the signal into the electric telescopic rod 16 through the controller, and the electric telescopic rod 16 drives the driving rod 8 to slide along the pad 9. During the sliding process, the driving rod 8 drives the sound damper 2 to move a certain distance along the door frame 11. When the sound damper 2 is disengaged from the door frame 11, the gear 25 then moves to mesh with the rack 12, and the rack 12 can drive the gear 25 to rotate, so that the sound damper 2 gradually opens a certain angle, and the user then passes through the sound damper 2. During the rotation of the gate plate 2 and the rotating column 24, the ratchet 20 is used to drive the ratchet wheel 34 to rotate a certain angle, so that the ratchet 20 and the injection pipe 32 rotate along the top of the accommodating plate 30. When the injection pipe 32 moves to dock with the oil groove 31, the lubricating oil in the oil pot 10 is introduced into the oil groove 31 through the injection pipe 32. Finally, the lubricating oil is introduced into the cushion block 9 through the lubricating hose 7 by the regulating valve 14 to lubricate the outer wall of the driving rod 8, and is introduced into the accommodating shell 26 to lubricate the gap between the rotating column 24 and the connecting block 18, so as to avoid the sound generated by the friction between the two and affecting the sound insulation effect.

[0034] Embodiment 2: A construction process for a banquet hall sound barrier structure comprises the following steps: S1: Install the door frame 11 on the surface of the wall 1 by embedding; S2: After the box body 3 and the top of the door frame 11 are fixedly connected, the top of the sound damper 2 and the bottom of the rotating column 24 are installed and fixed; S3: Install the touch switch 5 on the surface of the wall 1 by embedding, and electrically connect the touch switch 5 and the electric telescopic rod 16 through a wire; S4: After the box plate 6 is opened, a certain amount of lubricating oil is added into the oil pot 10, and the box plate 6 is closed to complete the installation operation of the entire sound barrier.

[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
