With the addition of an insulation layer, it has better thermal insulation performance. It is generally used for embedded walls or deep well pre-buried pipes.

[0003] In the prior art, such as the Chinese patent with publication number CN219734500U, a sound-absorbing PPR pipe structure is disclosed. The patent can insert the sound-absorbing cotton strip into the cotton groove, fix the sound-absorbing cotton strip inside the cotton groove through an arc plate, and then place the first semicircular plate and the second semicircular plate on the outer wall of the pipe body respectively, and fit the connecting plates on the outer surfaces thereof. The first semicircular plate and the second semicircular plate are fixed by inserting bolts into corresponding threaded holes and fitting nuts, so that the first semicircular plate and the second semicircular plate wrap the pipe body, and the sound-absorbing cotton strip and the sound-absorbing hole can absorb and weaken the sound of the liquid flow in the pipe body, thereby enhancing the sound absorption and sound insulation capabilities of the overall structure.

[0004] However, the above patent has some shortcomings. In actual use, the above patent fixes the silencer cotton strips on the surface of the pipe body through connecting plates and bolts. When the entire silencer assembly needs to be disassembled, multiple bolts need to be unscrewed multiple times, and the bolts will rust after long-term use, increasing the difficulty of disassembly. Therefore, a silencer type PPR pipe is proposed to solve the above problem. Utility Model Content

[0007] In some embodiments, a circular groove is formed on one side of each of the two connecting plates, and two ends of the two springs are fixedly connected to the inner wall of the circular groove and one side of the circular plate, respectively.

[0008] In some embodiments, one side of the two circular plates is fixedly connected to a same connecting rod, and one side of the two connecting plates is fixedly connected to a cover plate.

[0010] In some embodiments, the upper surfaces of the arc plate 1 and the arc plate 2 are each provided with a plurality of slots, and the inner walls of the plurality of slots are each plugged with sound-absorbing cotton strips.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] The utility model uses a sliding bar and a trapezoidal clamping block arranged on the arc plate one, which are squeezed by the end of the dovetail groove. The trapezoidal clamping block retracts through the elastic force of the spring and slides on the inner wall of the dovetail groove. When the trapezoidal clamping block below is clamped with the rectangular groove above, the sliding bar can be driven to slide, the limit is released, and it can slide down again until the trapezoidal clamping block above is clamped with the rectangular groove arranged above, so that the connection between the arc plate one and the arc plate two is realized. The gap between the connecting plate one and the connecting plate two can be filled by the provided silencer strip and the clamping groove, so as to improve the silencer effect. When disassembling, it is only necessary to pull the connecting rod to drive the sliding bar to slide, separate the trapezoidal clamping block from the rectangular clamping groove, realize the disassembly between the arc plate one and the arc plate two, and thus realize the disassembly and replacement of the silencer assembly.
