[0022] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 to 5The figure shows a preferred structure of the sound insulation device in this embodiment. As shown, the sound insulation device includes: a support body 1, a plug-in mechanism 2, a plug-in body 3, and two sound insulation mechanisms 4. The support body 1 is plate-shaped, and the two sound insulation mechanisms 4 are respectively disposed on both sides of the support body 1. Specifically, the support body 1 can be a rectangular plate, and the two sound insulation mechanisms 4 are respectively disposed on the left and right sides of the support body 1.

[0024] The insertion mechanism 2 and the insertion body 3 are respectively disposed at the two ends of the support body 1. Specifically, the length direction of the support body 1 ( Figure 1 A plug-in mechanism 2 is provided at one end of the support body 1 (shown in the direction from left to right), and a plug-in body 3 is provided at the other end along the length direction of the support body 1. The plug-in body 3 has a slot 31, and the plug-in mechanism 2 is used to be inserted into the slot 31 of the adjacent sound insulation device. Specifically, when two adjacent sound insulation devices are connected, the plug-in mechanism 2 of one sound insulation device is inserted into the slot 31 of the plug-in body 3 of the other sound insulation device.

[0025] As can be seen, in this embodiment, the two sound insulation mechanisms 4 are respectively arranged on both sides of the support body 1, which can effectively play the role of sound insulation and noise reduction, and improve the sound insulation effect. In addition, by inserting the plug-in mechanism 2 into the slot 31 of the plug-in body 3 in the adjacent sound insulation device, a detachable connection between the two adjacent sound insulation devices can be realized. Even if one of the two adjacent sound insulation devices is partially damaged, it is easy to disassemble the damaged sound insulation device and replace it, reducing the difficulty of replacement and solving the problem that the sound insulation board is not easy to replace and has poor sound insulation effect in the prior art.

[0026] See Figures 1 to 3 In the above embodiments, each sound insulation mechanism 4 includes: a sound-absorbing block 41, a sound-absorbing plate 42, and a sound-absorbing body 43. The sound-absorbing plate 42 and the sound-absorbing body 43 are parallel to the support body 1, and both are plate-shaped. The sound-absorbing plate 42 is disposed on one side wall of the support body 1, and the sound-absorbing body 43 is connected to the sound-absorbing plate 42, thus the sound-absorbing plate 42 is placed between the support body 1 and the sound-absorbing body 43. The sound-absorbing plate 42 is attached to the side wall of the support body 1, and the sound-absorbing body 43 has a receiving groove 432 on the side facing the sound-absorbing plate 42. Specifically, the sound-absorbing body 43 has a certain thickness, and the receiving groove 432 on the side of the sound-absorbing body 43 facing the sound-absorbing plate 42 is quadrilateral.

[0027] The sound-absorbing block 41 is disposed on the sound-absorbing plate 42 and is placed in the receiving groove 432. Specifically, the shape and size of the sound-absorbing block 41 match the shape and size of the receiving groove 432, and the size of the sound-absorbing block 41 is smaller than the size of the sound-absorbing plate 42.

[0028] The sound absorber 43 has multiple through holes 431 spaced apart, and each through hole 431 is connected to the receiving groove 432, that is, the receiving groove 432 can be connected to the outside through each through hole 431.

[0029] As can be seen, in this embodiment, sound-absorbing panels 42 are respectively provided on both sides of the support body 1, and sound-absorbing bodies 43 are provided on the outer side of both sound-absorbing panels 42. Each sound-absorbing body 43 has a receiving groove 432 for accommodating the sound-absorbing block 41 on the side facing the sound-absorbing panel 42. In addition, each sound-absorbing body 43 has multiple through holes 431. Then, the sound waves of external sound come into contact with the sound-absorbing block 41 and the sound-absorbing panel 42 in sequence after passing through the through holes 431 on the sound-absorbing body 43. The sound-absorbing block 41 and the sound-absorbing panel 42 buffer and absorb the sound waves, thereby improving the sound insulation and noise reduction effect.

[0030] To further improve the sound insulation and noise reduction effect of the sound insulation device, the support body 1 is provided with a filling groove, which is filled with sound insulation cotton. Specifically, the filling groove is opened in the center of the support body 1, and the filling groove runs through the thickness direction of the support body 1. The sound insulation cotton is placed in the filling groove, and the sound insulation cotton further reduces the propagation of sound waves.

[0031] See Figure 1 , Figure 4 and Figure 5 In the above embodiments, the insertion mechanism 2 includes: a insertion base 21, an insertion plate 22, and a locking mechanism. The insertion base 21 is connected to the end of the support body 1. Specifically, the insertion base 21 is perpendicular to the plate of the support body 1, and the insertion base 21 and the support body 1 form a T-shape. The height of the insertion base 21 (… Figure 1 The direction shown from top to bottom is the height direction, and the height of support 1 is ( Figure 1 The height direction (shown from top to bottom) is equal. The connector 3 is located at the other end of the support 1, perpendicular to the plate of the support 1. The connector 3 and the support 1 form a T-shape, thus the connector 3, connector seat 21, and support 1 form an "I"-shaped structure. The two ends of the two sound insulation mechanisms 4 are in contact with the connector 3 and connector seat 21 respectively. The slot 31 is along the height direction of the connector 3 (…). Figure 1 (As shown in the top-to-bottom direction) extends, and the height of the slot 31 is equal to the height of the plug body 3, and the height of the plug body 3 is equal to the height of the support body 1.

[0032] The connector plate 22 is along the height direction of the connector 21. Figure 1Extending in the direction shown from top to bottom, the plug plate 22 is disposed on the side wall of the plug-in base 21. Specifically, one side wall of the plug-in base 21 is connected to the support body 1, and the plug plate 22 is disposed on the other side wall of the plug-in base 21. The plug plate 22 is perpendicular to the side wall of the plug-in base 21. The height of the plug plate 22 can be equal to the height of the support body 1. The plug plate 22 is inserted into the slot 31 of the plug body 3 in the adjacent sound insulation device.

[0033] A locking mechanism is provided between the connector 21 and the connector 3, and the locking mechanism is used to lock the connector 21 and the connector 3 together.

[0034] In practice, there are two plug-in boards 22 arranged side by side, and correspondingly, there are also two slots 31 arranged side by side. The two plug-in boards 22 are inserted into the two slots 31 one by one.

[0035] As can be seen, in this embodiment, when the two sound insulation devices are connected, the plug plate 22 in one sound insulation device is inserted into the slot 31 in the other sound insulation device, and the plug seat 21 in one sound insulation device is locked into the plug body 3 in the other sound insulation device by the locking mechanism, thereby achieving stable fixation of the two sound insulation devices and ensuring normal use of the sound insulation devices.

[0036] See Figure 1 , Figure 4 and Figure 5 In the above embodiment, the locking mechanism includes a drive mechanism 23 and at least one locking component 24. The plug-in base 21 is hollow, and the drive mechanism 23 is disposed within the plug-in base 21. The locking components 24 are spaced apart on the sidewalls of the plug-in base 21, and each locking component 24 is connected to the drive mechanism 23.

[0037] The connector 3 has at least one locking slot 32, and each locking component 24 corresponds to each locking slot 32. When the connector plate 22 is inserted into the slot 31, each locking component 24 is inserted into the corresponding locking slot 32.

[0038] Preferably, each locking component 24 is evenly and spaced along the height direction of the plug-in base 21, and the position of each locking slot 32 corresponds one-to-one with the position of each locking component 24.

[0039] The drive mechanism 23 is used to drive each locking component 24 to rotate in the corresponding locking groove 32 so that the plug socket 21 is locked with the plug body 3.

[0040] Preferably, each locking assembly 24 includes a rotating rod 241 and a locking rod 242. The rotating rod 241 is rotatably inserted through the side wall of the connector 21. The first end of the rotating rod 241 is placed inside the connector 21 and connected to the drive mechanism 23. The second end of the rotating rod 241 is placed outside the connector 21 and is perpendicularly connected to the locking rod 242. The locking rod 242 is placed outside the connector 21, and the rotating rod 241 and the locking rod 242 form a T-shape.

[0041] See Figure 5 Each locking groove 32 has a certain depth and includes a insertion portion 321 and a limiting portion 322. The insertion portion 321 is located on the side wall of the insertion body 3 and extends towards the support body 1. A limiting portion 322 is located at the bottom of the insertion portion 321, perpendicular to and connected to the insertion portion 321. If the lateral distance between the insertion portion 321 and the limiting portion 322 is less than the lateral distance between the limiting portion 322, then the insertion portion 321 and the limiting portion 322 form a T-shape, i.e., the locking groove 32 is T-shaped. The rotating rod 241 is rotatably placed within the insertion portion 321, and the locking rod 242 is rotatably placed within the limiting portion 322. Both the insertion portion 321 and the limiting portion 322 have a preset depth, which ensures that the rotating rod 241 and the locking rod 242 can rotate freely. This embodiment does not impose any restrictions on the numerical value of the depth.

[0042] Specifically, both the rotating rod 241 and the locking rod 242 are inserted into the insertion part 321. The rotating rod 241 is placed inside the insertion part 321, and the locking rod 242 is placed inside the limiting part 322. The driving mechanism 23 drives the rotating rod 241 to rotate inside the insertion part 321, which in turn drives the locking rod 242 to rotate inside the limiting part 322. When the locking rod 242 rotates to be parallel to the limiting part 322, that is, when the locking rod 242 and the rotating rod 241 are exactly T-shaped in the locking groove 32, the locking rod 242 and the rotating rod 241 can match the T-shape of the locking groove 32. At this time, the locking rod 242 is limited by the limiting part 322 to prevent the locking rod 242 from sliding out of the limiting part 322 and the insertion part 321, thereby ensuring that the locking rod 242 and the rotating rod 241 are locked with the locking groove 32, that is, ensuring that the insertion body 3 is locked with the insertion seat 21.

[0043] As can be seen, in this embodiment, after the rotating rod 241 is inserted into the insertion part 321, the locking rod 242 rotates within the limiting part 322. The locking rod 242 is blocked by the limiting part 322, thereby achieving locking. The structure is simple and easy to implement.

[0044] See also Figure 1 , Figure 4 and Figure 5In the above embodiment, the drive mechanism 23 includes: a drive block 231, a drive rod 232, and at least one transmission component. The top of the plug-in socket 21 ( Figure 4 An opening is provided in the upper part (as shown), and the drive block 231 is rotatably disposed in the opening, so that the drive block 231 can rotate freely in the opening. Furthermore, the drive block 231 is placed on top of the plug-in base 21 for easy operation by the staff.

[0045] The drive rod 232 is connected to the drive block 231. The drive rod 232 extends along the height direction of the connector 21. Specifically, the length direction of the drive rod 232 ( Figure 4 The direction shown (from top to bottom) is consistent with the height direction of the connector 21, and the drive rod 232 is arranged inside the connector 21 along the height direction of the connector 21. The drive block 231 and the drive rod 232 can be arranged close to the side of the connector 21 inside the connector 21.

[0046] Each transmission component is spaced apart along the length of the drive rod 232, preferably evenly distributed on the drive rod 232. Each transmission component corresponds one-to-one with each locking component 24, and each transmission component is connected to its corresponding locking component 24. Specifically, each transmission component is connected to the rotating rod 241 in its corresponding locking component 24.

[0047] The drive block 231 is used to drive the drive rod 232 to rotate, which in turn drives the locking components 24 to rotate through the transmission components.

[0048] Each transmission component includes a movable block 233, a movable plate 234, and a gear 235. The outer wall of the drive rod 232 is threaded, and the movable block 233 has a through hole with threads on its inner wall. The through hole of the movable block 233 is screwed to the drive rod 232. Specifically, the movable block 233 can be a nut.

[0049] The movable plate 234 is connected to the movable block 233, the movable plate 234 is parallel to the drive rod 232, and a rack is provided on one side of the movable plate 234. The gear 235 is rotatably disposed in the plug-in seat 21, and the gear 235 meshes with the rack. The gear 235 is connected to the rotating rod 241 in the locking assembly 24.

[0050] Preferably, each transmission component further includes a limiting block 236. The limiting block 236 is connected to the moving block 233, and a limiting groove 237 is formed in the side wall of the insertion seat 21. The limiting block 236 is slidably disposed within the limiting groove 237. Specifically, the limiting block 236 and the moving plate 234 are respectively disposed on opposite sides of the moving block 233. The limiting groove 237 is formed along the height direction of the insertion seat 21. The setting of the limiting block 236 and the limiting groove 237 restricts the movement trajectory of the moving plate 234, causing the moving plate 234 to move along the length direction of the drive rod 232, thereby ensuring that the moving plate 234 drives the rotating rod 241 to rotate via the gear 235.

[0051] As can be seen, in this embodiment, the drive mechanism 23 has a simple structure and is easy to implement.

[0052] Combination Figures 1 to 5 The usage process of the soundproofing device is described as follows: Before connecting the two soundproofing devices, rotate the drive block 231. The drive block 231 drives the drive rod 232 to rotate, causing the moving block 233 on the drive rod 232 to move up and down along the drive rod 232, which in turn drives the moving plate 234 to move. Since the moving plate 234 meshes with the gear 235 through a rack and pinion, the movement of the moving plate 234 drives the rotation of the gear 235, which in turn drives the rotation of the rotating rod 241, making the rotating rod 241 and the locking rod 242 vertical. When the two soundproofing devices are connected, the plug plate 22 of one soundproofing device is inserted into the slot 31 of the plug body 3 of the other soundproofing device. The rotating rod 241 and the locking rod 242 are inserted from the corresponding locking grooves 32. The rotating rod 241 is placed in the plug part 321 of the locking groove 32, and the locking rod 242 is placed in the limiting part 322 of the locking groove 32. Rotating the drive block 231 causes the drive rod 232 to rotate, which in turn causes the moving block 233 to move, which in turn causes the rotating rod 241 to rotate. This causes the rotating rod 241 to rotate within the insertion part 321, and the locking rod 242 to rotate within the limiting part 322. This continues until the locking rod 242 is horizontal, at which point the locking rod 242 is restricted within the locking groove 32, preventing the locking rod 242 from disengaging from the locking groove 32. This achieves the locking of the insertion body 3 and the insertion seat 21.

[0053] After the two sound insulation devices are installed, sound enters the sound absorber 43. The sound waves generated by the sound enter the interior of the sound absorber 43 and come into contact with the sound absorbing block 41. The sound absorbing block 41 buffers and absorbs the sound waves. In addition, the sound absorbing cotton in the support body 1 further reduces the spread of sound waves.

[0054] In summary, in this embodiment, the two sound insulation mechanisms 4 are respectively arranged on both sides of the support body 1, which can effectively play the role of sound insulation and noise reduction, thus improving the sound insulation effect. Furthermore, by inserting the plug-in mechanism 2 into the slot 31 of the plug-in body 3 in the adjacent sound insulation device, a detachable connection between the two adjacent sound insulation devices can be realized. Even if one of the two adjacent sound insulation devices is partially damaged, it is easy to disassemble the damaged sound insulation device and replace it, thus reducing the difficulty of replacement.

[0055] It should be noted that in the description of this invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation.
