After the factory building is built, the machines will generate loud noise when running inside. The existing prefabricated components themselves are cast by reinforced concrete and lack noise reduction measures. As a result, the noise generated during production in the factory will spread to the surroundings, causing noise pollution. In view of this, the present utility model is specially proposed.

[0006] In order to improve the sound insulation effect, further, the grid plates are two symmetrically arranged, and the vacuum chamber is symmetrically provided with a second sound absorbing plate between the two grid plates.

[0007] In order to improve the sound insulation performance of the first sound absorbing board and the second sound absorbing board, further, the second sound absorbing board is provided with serrated protrusions at equal intervals on one side away from the grille plate, and the first sound absorbing board is provided with a plurality of honeycomb holes.

[0008] In order to more conveniently connect the two component bodies, further, the limit block is tiltedly arranged away from one end of the tensioning spring.

[0009] In order to prevent the limit block from moving, further, one inclined end of the limit block is tightly attached to the component body through a magnetic block.

[0010] In order to facilitate filling and sound absorption of the gap between the two component bodies, further, a sound-absorbing sponge is arranged on one side of the component body located at the slot.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: compared with the existing prefabricated components, the utility model realizes the rapid loading and unloading of the component body through the coordinated use of limit blocks and plug-in blocks, and utilizes the first sound-absorbing panel and the vacuum chamber to eliminate noise, thereby effectively improving the noise reduction effect.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4A passive noise reduction and sound insulation component comprises a component body 1, a plurality of plug blocks 101 are fixedly connected to one side of the component body 1 at equal intervals, a slot used in cooperation with the plug block 101 is provided on the side of the component body 1 away from the plug block 101, a slide groove connected to the slot is provided in the component body 1, a limit block 2 is slidably connected in the slide groove, the limit block 2 is connected to the component body 1 through a tensioning spring 201, a moving rod 202 is fixedly connected to one end of the limit block 2 close to the tensioning spring 201, the moving rod 202 extends out of the component body 1, a jack used in cooperation with the limit block 2 is provided on the plug block 101, a vacuum chamber is provided in the component body 1, a first sound absorbing board 3 is symmetrically fixedly connected in the vacuum chamber, and a grille plate 4 is provided between the two first sound absorbing boards 3 in the vacuum chamber;

[0022] The grid plates 4 are two symmetrically arranged, and the vacuum chamber is located between the two grid plates 4 and a second sound absorbing plate 5 is symmetrically arranged.

[0023] When the prefabricated components need to be connected, the moving rod 202 of one component body 1 is pulled outward, and the moving rod 202 will leave the slot with the limiting block 2, and then the plug block 101 of the other component body 1 is inserted into the slot of this component body 1, and finally the moving rod 202 is released. Under the action of the tensioning spring 201, the limiting block 2 moves back into the insertion hole of the plug block 101, and the plug block 101 is limited and fixed to achieve the connection of the components. When disassembly is required, the moving rod 202 is pulled, and the limiting block 2 leaves the insertion hole. At this time, the plug block 101 can be removed from the slot to achieve disassembly between the components. When the component body 1 is in use, the noise generated will be absorbed by the first sound absorbing board 3 and the vacuum cavity in turn, thereby achieving noise reduction and sound insulation. Compared with the existing prefabricated components, the coordinated use of the limiting block 2 and the plug block 101 can achieve rapid loading and unloading of the component body 1, and the first sound absorbing board 3 and the vacuum cavity are used to eliminate noise, thereby effectively improving the noise reduction effect.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 4 , a passive noise reduction and sound insulation component, which is basically the same as Example 1, and further, a side of the second sound absorbing plate 5 away from the grille plate 4 is equidistantly provided with serrated protrusions, and a plurality of honeycomb holes are opened on the first sound absorbing plate 3. The serrated protrusions and the honeycomb holes can make the second sound absorbing plate 5 and the first sound absorbing plate 3 have stronger sound absorption performance, and effectively improve the sound absorption effect.

[0026] The limit block 2 is tilted away from one end of the tensioning spring 201. When connecting the two component bodies 1, there is no need to pull the moving rod 202. After the plug 101 enters the slot, the limit block 2 can be pushed to move to one side of the tensioning spring 201, and then the limit block 2 is moved back into the socket using the tensioning spring 201 for limiting and fixing, which effectively improves the convenience during connection.

[0027] The inclined end of the limit block 2 is tightly attached to the component body 1 through the magnetic block, so that the limit block 2 and the component body 1 are tightly attached to each other through the magnetic block, so as to avoid the limit block 2 moving after the limit is fixed and affecting the fixing effect between the two component bodies 1.

[0028] A sound-absorbing sponge 102 is provided on one side of the component body 1 located at the slot to fill the connection gap between the two component bodies 1 and absorb the noise transmitted in the gap, thereby effectively improving the noise reduction and sound insulation effect.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
