[0020] The present invention will be further described below with reference to specific embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, an easily installed railway sound insulation member of this embodiment includes a sound insulation sheet 1. A base 2 is provided at the lower end of the sound insulation sheet 1. When the sound insulation member is erected and placed, the extended portion of the lower end of the base 2 is embedded in the soil, and the lower end of the sound insulation sheet 1 is clamped on the upper end of the base 2. After the base 2 is fixed, the sound insulation sheet 1 is also fixed and erected. By installing multiple sound insulation sheets 1 in sequence horizontally, railway sound insulation can be achieved.

[0023] Among them, Figure 2 As shown, a connecting plate 8 is provided on one side of the interior of the sound insulation sheet 1. Springs 13 are provided at both upper and lower ends between the connecting plate 8 and the sound insulation sheet 1. By pulling out the connecting plate 8, the connection between two adjacent sound insulation sheets 1 can be achieved. The connected springs 13 can continuously pull the connecting plate 8 when the connecting plate 8 is not in use, so that the connecting plate 8 is reset and stored inside the sound insulation sheet 1.

[0024] In addition, a reserved groove 9 is provided on the other side of the interior of the sound insulation piece 1, and a limiting strip 3 is provided on one side outside the reserved groove 9. After the connecting plate 8 is inserted into the reserved groove 9, the limiting strip 3 slides into the reserved groove 9 to limit the discharge of the connecting plate 8. By limiting the connecting plate 8, the connection of two adjacent railway sound insulation pieces can be achieved.

[0025] In order to improve the stability of the connection between two adjacent sound insulation sheets 1, Figure 4 As shown, sliding rails 10 are provided at both upper and lower ends of the outer portion of the limiting bar 3, and the sliding rails 10 are recessed inside the sound insulation sheet 1. The inner portion of the sliding rails 10 is connected to the upper and lower slots of the outer portion of the limiting bar 3. The recess of the sliding rails 10 facilitates the insertion of the limiting bar 3, thereby improving the stability of the limiting bar 3 after connection.

[0026] like Figure 5 As shown, in order to prevent the connecting plate 8 from falling off, a support rod 12 is provided on the outside of the spring 13, and a transmission rod 11 is provided on the outside of the support rod 12. The transmission rod 11 is welded and fixed to the connecting plate 8, and the support rod 12 is welded and fixed to the sound insulation plate 1. When the connecting plate 8 is pulled and extended outside the sound insulation plate 1, the transmission rod 11 will slide outside the support rod 12. The restriction of the transmission rod 11 by the support rod 12 can improve the stability of the connection of the connecting plate 8.

[0027] The transmission rod 11 will be embedded in the reserved groove 9 together with the connecting plate 8. Figure 4 As shown, the inner recess of the limiting bar 3 is provided with a reserved cavity 5, the two reserved cavities 5 correspond to the connection positions of the two transmission rods 11 respectively, and the reserved cavities 5 are connected to the outer slots of the transmission rods 11;

[0028] In order to improve the stability of the connection between the limiting strip 3 and the sound insulation sheet 1, and to improve the stability of the limiting strip 3 restraining the connecting plate 8, one side of the limiting strip 3 is fixedly connected to one side of the sound insulation sheet 1 by a bolt 4;

[0029] A sliding block 6 is provided in the middle of one end of the sound insulation sheet 1, and the sliding block 6 is welded and fixed to the sound insulation sheet 1, and a latch 7 penetrates and fixes the base 2 and the sliding block 6:

[0030] In order to improve the sound insulation effect, Figure 2 As shown, the other end of the sound insulation sheet 1 is bonded with sound-absorbing cotton 14 by glue.

[0031] When the sound insulation sheet 1 slides on the upper end of the base 2, the sound insulation sheet 1 can only slide toward the side with the reserved groove 9, such as Figure 3 and Figure 5 As shown, the upper end of the base 2 near the side of the connecting plate 8 restricts the sound insulation sheet 1 , and the restriction of the base 2 can prevent the sound insulation sheet 1 from sliding toward the side of the connecting plate 8 .

[0032] Working principle: When installing railway sound insulation and performing sound insulation, the first railway sound insulation is embedded into the soil through the base 2 to complete the installation. The second railway sound insulation is first placed against one side of the first railway sound insulation, and the base 2 is still embedded into the soil to complete the placement. The latch 7 of the second railway sound insulation is taken out, and the sound insulation sheet 1 at the upper end of the second railway sound insulation is slid out. After the bolt 4 for fixing the limiting strip 3 of the first railway sound insulation is rotated and removed, the limiting strip 3 is taken out to expose the reserved groove 9 inside. The connecting plate 8 is slid out from the second railway sound insulation, and the connecting plate 8 is pressed and moved to the inside of the reserved groove 9. The sliding plug Insert the limiting strip 3 into the sliding rail 10, and the transmission rod 11 connecting the connecting plate 8 is embedded in the reserved cavity 5. After the limiting strip 3 is completely inserted, it is embedded and fixed and connected by the bolt 4. Slide to make the second railway sound insulation piece, so that the sound insulation pieces 1 of the two railway sound insulation pieces fit together. After assembly, the pin 7 is used to penetrate the sound insulation piece 1 and embed it into the base 2 to complete the fixation of the sound insulation piece 1, thereby realizing the combination between the two adjacent sound insulation pieces 1. When disassembling, there is no need to slide the sound insulation piece 1. After removing the bolt 4, take out the limiting strip 3. The resilience of the spring 13 will drive the connecting plate 8 to shrink into the inside of the sound insulation piece 1, and the two railway sound insulation pieces can be disconnected.
