[0001] The utility model belongs to the technical field of sound insulation boards, and in particular relates to an assembling structure of sound insulation boards for tunnels. Background Art

[0002] With the development of economy and society, noise has become a new source of pollution. People are exposed to various noise pollution for a long time, which will seriously affect their normal work, study and life. In order to solve the noise problem, people use a large number of sound insulation panels in buildings to achieve the purpose of noise isolation. Tunnels are relatively closed spaces, so sound insulation panels need to be installed to isolate noise.

[0003] During installation, two adjacent sound insulation boards need to be connected so that the adjacent sound insulation boards can restrict each other and ensure that the connection is firm to form mutual restriction and overall stability. However, when the sound insulation boards are currently connected, the positions between the boards are usually fixed and installed horizontally. However, places like tunnels usually have protrusions and bends, so the connection between the boards is inconvenient and the angle is fixed. Therefore, a sound insulation board assembly structure for tunnels is proposed. Summary of the invention

[0011] By adopting the above technical solution and utilizing the constraint locking assembly, after the second connecting strip is put on the outside of the connecting column, the branch end of the limit frame enters the corresponding arc groove, which can prevent movement in the length direction of the connecting column and ensure the stability of the connection. After the branch end of the limit frame enters the slot, the angle can be limited to ensure that it will not rotate at will, which is convenient for angle adjustment and also for angle limitation.

[0012] Furthermore, one end of the spring is connected to the top of the movable plate, and the other end of the spring is fixedly connected to the groove wall of the movable groove, and the movable plate matches the movable groove.

[0013] By adopting the above technical solution, the limit frame can be reset and pulled by the spring, and at the same time the limit frame is restricted to prevent the limit frame from being separated from the arc groove and the clamping groove.

[0014] Furthermore, the two branch ends of the limiting frame are respectively inserted into the two arc-shaped grooves, and the branch ends of the limiting frame match the slots.

[0015] By adopting the above technical solution, the rotation of the angle can be limited by inserting the support end of the limiting frame into the arc groove.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model utilizes a restraining locking assembly. After the second connecting strip is sleeved on the outside of the connecting column, the branch end of the limit frame enters the corresponding arc groove, which can prevent movement in the length direction of the connecting column and ensure the stability of the connection. After the branch end of the limit frame enters the slot, the angle can be limited to ensure that it will not rotate at will, which is convenient for angle adjustment and also for angle limitation.

The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4The embodiment of the utility model proposes an assembling structure of sound insulation board for tunnel, including a sound insulation board 1, a connecting strip 2 is installed on one side of the sound insulation board 1, and a connecting column 3 is fixedly connected to the side of the connecting strip 2 away from the sound insulation board 1, and two arc grooves 4 are provided on the surface of the connecting column 3, and a connecting strip 2 5 is installed on the other side of the sound insulation board 1, and a jacket shell 6 is fixedly connected to the side of the connecting strip 2 5 away from the sound insulation board 1, and a constraint locking component is arranged on the jacket shell 6, and the sound insulation board 1 can be arc-shaped when necessary.

[0028] Furthermore, the inner diameter of the second connecting strip 5 is slightly larger than the outer diameter of the connecting column 3, and the second connecting strip 5 is slidably sleeved on the outer side of the connecting column 3, so that the connection between adjacent ones can be ensured.

[0029] The central angle corresponding to the connecting strip 25 is greater than 200 degrees. The connecting strip 25 is sleeved on the outside of the connecting column 3, and the connecting strip 25 covers the connecting column 3 for more than 180 degrees, which can prevent the connecting strip 25 from detaching from the connecting column 3 and ensure the stability of the connection.

[0030] The constraint locking assembly includes a sliding groove 7 opened on the outer shell 6, a limiting frame 8 is slidably connected in the sliding groove 7, a pulling frame 9 is installed on the top of the limiting frame 8, movable plates 11 are installed on both sides of the limiting frame 8, and a spring 12 is installed on the top of the movable plate 11. Moving grooves 10 are opened on both sides of the sliding groove 7, and the bottom of the arc groove 4 is opened with evenly distributed card grooves 13. By utilizing the constraint locking assembly, after the connecting strip 25 is sleeved on the outside of the connecting column 3, the branch end of the limiting frame 8 enters the corresponding arc groove 4, which can prevent movement in the length direction of the connecting column 3 and ensure the stability of the connection. After the branch end of the limiting frame 8 enters the card groove 13, the angle can be limited to ensure that it will not rotate at will, so that it is convenient for angle adjustment and also for angle limitation.

[0031] One end of the spring 12 is connected to the top of the movable plate 11, and the other end of the spring 12 is fixedly connected to the groove wall of the movable groove 10. The movable plate 11 matches the movable groove 10. The spring 12 can be used to reset the limit frame 8 for traction, and at the same time, the limit frame 8 is restricted to prevent the limit frame 8 from detaching from the arc groove 4 and the card groove 13.

[0032] The two branch ends of the limiting frame 8 are respectively inserted into the two arc-shaped grooves 4, and the branch ends of the limiting frame 8 match the clamping grooves 13.

[0033] The specific implementation method is as follows: when in use, the two sound insulation boards 1 are connected, the outer shell 6 is slidably inserted into the connecting column 3, and the pulling frame 9 is pulled while sliding to allow the branch end of the limit frame 8 to retract into the outer shell 6, so that the limit frame 8 will not hinder the sliding of the outer shell 6 on the connecting column 3. When it slides to the specified position, that is, the limit frame 8 moves to the top of the arc groove 4, and then the limit frame 8 is released. Under the action of the spring 12, the limit frame 8 is driven to reset, so that the branch end of the limit frame 8 enters the arc groove 4 and enters the card slot 1 in the arc groove 4. 3, so that the sound insulation board 1 can be restricted and will not rotate at will. At the same time, entering the arc groove 4 also restricts the movement of the connecting column 3 in the length direction, which is convenient for the connection between two adjacent sound insulation boards 1, simple and convenient. At the same time, when the angle needs to be rotated during installation, pull the pulling frame 9 and the limit frame 8 to allow the support end of the limit frame 8 to separate from the slot 13 but not from the arc groove 4. At this time, rotate the sound insulation board 1 to convert the angle, and then release the limit frame 8 to reset the limit frame 8 for restriction.
