[0020] Please refer to Figures 1 to 5 , wherein, Figure 1 It is a schematic structural diagram of the double-layer sound insulation structure of the wooden door of the present utility model, Figure 2 It is of the present utility model Figure 1 Partial enlarged view of the structure at position A, Figure 3 It is a schematic structural diagram of another direction of the double-layer sound insulation structure of the wooden door of the present utility model, Figure 4 It is a schematic structural diagram inside the door panel of the double-layer sound insulation structure of the wooden door of the present utility model, Figure 5 It is a schematic structural diagram of the sound insulation board of the double-layer sound insulation structure of the wooden door of the present utility model.

[0021] The present utility model provides a double-layer sound insulation structure for a wooden door, including a door panel 101, four pull rings 103, two sound insulation boards 102 and an installation mechanism. The installation mechanism includes two clamping blocks 106, four slide bars 104, four slide grooves 107 and a locking assembly. The installation mechanism has an installation groove 105. The locking assembly includes a hinge 113, four bolts 114, a cover plate 115, a fixed column 116, a fixed clamping block 108, three pressing blocks 117, an installation frame 109, a limit rod 110 and a telescopic kit. The telescopic kit includes an installation plate 112 and a telescopic spring 111. Through the foregoing solution, in the prior art, the door panel 101 adopts an integral structure. When the structure inside the wooden door is damaged, it is difficult to disassemble the door panel 101, resulting in inconvenience for operators to repair and reducing the convenience.

[0022] In this embodiment, the two clamping blocks 106 are fixedly connected to the door panel 101 and are respectively located at both ends of the installation groove 105. The four sliding bars 104 are respectively fixedly connected to both ends of the two sound insulation boards 102. The four sliding grooves 107 are respectively arranged on the two clamping blocks 106. The four sliding bars 104 are respectively slidably connected to the two clamping blocks 106 and are respectively located in the four sliding grooves 107. The locking assembly is arranged on the door panel 101 and is located above the installation groove 105. When installing the sound insulation board 102, align the two sliding bars 104 on both sides of the sound insulation board 102 with the two sliding grooves 107 on the two clamping blocks 106 respectively, and insert the two sliding bars 104 into the two sliding grooves 107 until the two sliding bars 104 slide to the bottom of the two sliding grooves 107, then the installation of the sound insulation board 102 is completed. Install the other sound insulation board 102 in the above manner, and then seal the installation groove 105 through the locking assembly. When the sound insulation board 102 is damaged, control the locking assembly to open the installation groove 105, and pull out the damaged sound insulation board 102 upward. After the maintenance personnel repair the damaged sound insulation board 102, reinstall it. The installation and disassembly of the sound insulation board 102 in the door panel 101 are relatively simple, which is convenient for the operator to inspect and repair the sound insulation board 102 in the door panel 101, thereby increasing the convenience of using the wooden door.

[0023] Further, two of the bolts 114 are threadedly connected to one end of the hinge 113 and the door panel 101, and the other two bolts 114 are threadedly connected to the other end of the hinge 113 and the cover plate 115.

[0024] In this embodiment, after the installation of the sound insulation board 102 is completed, rotate the cover plate 115. The cover plate 115 rotates around the hinge 113 as the central axis, and the cover plate 115 seals the installation groove 105 to prevent external dust from entering the installation groove 105.

[0025] Further, the fixed column 116 is fixedly connected to the cover plate 115 and is located at the end of the cover plate 115 away from the hinge 113. The fixed clamping block 108 is fixedly connected to the door panel 101. The mounting bracket 109 is fixedly connected to the fixed clamping block 108. The limiting rod 110 is slidably connected to the mounting bracket 109 and the fixed clamping block 108 and penetrates through the mounting bracket 109 and the fixed clamping block 108. The telescopic kit is arranged on the limiting rod 110 and the mounting bracket 109.

[0026] Further, the mounting plate 112 is fixedly connected to the limiting rod 110 and is located between the fixed clamping block 108 and the mounting bracket 109. Both ends of the telescopic spring 111 are fixedly connected to the mounting plate 112 and the mounting bracket 109 respectively, and the limiting rod 110 is located inside the telescopic spring 111.

[0027] In this embodiment, after the sound insulation board 102 is installed, pull the limiting rod 110 outwards. The telescopic spring 111 contracts, and the limiting rod 110 is pulled out of the fixed clamping block 108. Rotate the cover plate 115. The cover plate 115 rotates around the hinge 113 as the central axis. The cover plate 115 seals the mounting groove 105. At this time, the fixing post 116 on the cover plate 115 enters the fixed clamping block 108. Then release the limiting rod 110. The telescopic spring 111 elongates under the action of its own elastic potential energy and drives the limiting rod 110 to insert into the fixed clamping block 108, fixing the fixing post 116 in the fixed clamping block 108 and the limiting rod 110. The cover plate 115 is limited and fixed, ensuring that the cover plate 115 will not be opened under the action of external force, increasing the stability of the cover plate 115.

[0028] Further, the three pressing blocks 117 are fixedly connected to the cover plate 115 and are located at one end of the cover plate 115 close to the sound insulation board 102.

[0029] In this embodiment, when the cover plate 115 seals the mounting groove 105, the three pressing blocks 117 are respectively in close contact with the two sound insulation boards 102. The three pressing blocks 117 fix the sound insulation board 102 in the mounting groove 105, ensuring that the sound insulation board 102 remains fixed under the action of external force and will not slide in the sliding groove 107.

[0030] Further, the four pull rings 103 are respectively fixedly connected to the two sound insulation boards 102 and are located above the two sound insulation boards 102.

[0031] In this embodiment, when disassembling the sound insulation board 102, the operator pulls up the two pull rings 103 to facilitate the disassembly of the sound insulation board 102, increasing the convenience of the device.

[0032] When installing the sound insulation board 102 using the present utility model, align the two slide bars 104 on both sides of the sound insulation board 102 with the two slide grooves 107 on the two clamping blocks 106 respectively, and insert the two slide bars 104 into the two slide grooves 107 until the two slide bars 104 slide to the bottom of the two slide grooves 107, then the installation of the sound insulation board 102 is completed. Install another sound insulation board 102 in the same way. After the installation of the sound insulation board 102 is completed, pull the limit rod 110 outwards, the telescopic spring 111 contracts, and the limit rod 110 is pulled out of the fixed clamping block 108. Rotate the cover plate 115, and the cover plate 115 rotates around the hinge 113 as the central axis. The cover plate 115 seals the installation groove 105. At this time, the fixed column 116 on the cover plate 115 enters the fixed clamping block 108. Then release the limit rod 110, and the telescopic spring 111 elongates under the action of its own elastic potential energy, and drives the limit rod 110 to insert into the fixed clamping block 108, fixing the fixed column 116 in the fixed clamping block 108 and the limit rod 110, and the cover plate 115 is limited and fixed to ensure that the cover plate 115 will not be opened under the action of external force. When the sound insulation board 102 is damaged, control the cover plate 115 to rotate to open the installation groove 105, and pull out the damaged sound insulation board 102 upwards. After the maintenance personnel repair the damaged sound insulation board 102, reinstall it. The installation and disassembly of the sound insulation board 102 in the door panel 101 are relatively simple, which is convenient for the operator to inspect and repair the sound insulation board 102 in the door panel 101, thereby increasing the convenience of using the wooden door.
