[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A track sound-absorbing device for an exhibition hall, comprising:

[0026] The main body comprises a bottom plate 1, on the surface of which a sound absorbing plate 11 is fixedly mounted;

[0027] The mounting mechanism comprises a guide rod 2, which is fixedly connected to the upper surface of the bottom plate 1, and a plurality of groups of moving blocks 21 are slidably connected to the surface of the guide rod 2, and a first bolt 22 is threadedly connected to the surface of the moving block 21, and a sound-absorbing bracket 23 is fixedly connected to the surface of the moving block 21, and a nut 24 is fixedly connected to the surface of the sound-absorbing bracket 23, and a second bolt 25 is threadedly connected to the surface of the nut 24, and a disc 26 is fixedly connected to the surface of the second bolt 25, and both sides of the sound-absorbing bracket 23 are slots, and the sound-absorbing panel 11 is placed on the slots of the sound-absorbing bracket 23. The mounting mechanism can mount sound-absorbing panels 11 of different specifications on the sound-absorbing bracket 23, so as to facilitate the installation of the sound-absorbing panel 11.

[0028] Furthermore, a limiting mechanism is provided on the surface of the sound-absorbing bracket 23, and the limiting mechanism includes a baffle 3, which is slidably connected to the surface of the sound-absorbing bracket 23, and a fixing block 31 is fixedly connected to the top of the sound-absorbing bracket 23, and a spring 32 is fixedly connected to the surface of the fixing block 31, and a limiting block 33 is fixedly connected to the surface of the spring 32, and the limiting block 33 slides on the guide groove of the fixing block 31, and its limiting mechanism can limit the position of the baffle 3 on the sound-absorbing bracket 23, and can also cancel the restriction on the baffle 3 on the sound-absorbing bracket 23, so that the baffle 3 is removed from the sound-absorbing bracket 23. In the process of installing the sound-absorbing panel 11, it is avoided to install the sound-absorbing panel 11 from the top of the sound-absorbing bracket 23, so that the workers install it from the side of the sound-absorbing bracket 23 close to the baffle 3, thereby improving the efficiency of the workers in installing the sound-absorbing panel 11 on the sound-absorbing bracket 23.

[0029] Furthermore, a rectangular groove is provided on the surface of the moving block 21, and the moving block 21 slides on the surface of the guide rod 2 through the rectangular groove. The moving block 21 slides on the surface of the bottom plate 1 through the guide rod 2, and the sound-absorbing bracket 23 slides on the surface of the bottom plate 1 through the moving block 21. The sliding of the moving block 21 changes the position of the sound-absorbing bracket 23 on the bottom plate 1. The sound-absorbing bracket 23 will be linearly and evenly distributed on the upper surface of the bottom plate 1, and a group of sound-absorbing panels 11 is installed between the two groups of sound-absorbing brackets 23.

[0030] Furthermore, a plurality of groups of circular holes are provided on the surface of the guide rod 2 and are evenly arranged linearly. The first bolt 22 passes through the circular holes of the guide rod 2 on the moving block 21. The first bolt 22 restricts the moving block 21 on the surface of the base plate 1, thereby restricting the sound-absorbing bracket 23 on the upper surface of the base plate 1. The moving block 21 changes the position of the sound-absorbing bracket 23 on the base plate 1, thereby facilitating the installation of sound-absorbing panels 11 of different lengths.

[0031] Furthermore, a circular hole is opened on the surface of the sound-absorbing bracket 23, and the nut 24 is fixedly connected to the circular hole of the sound-absorbing bracket 23. The second bolt 25 changes the position of the disc 26 on the sound-absorbing bracket 23 through the nut 24, and the disc 26 squeezes and fixes the sound-absorbing panel 11 on the slot of the sound-absorbing bracket 23. The sound-absorbing panel 11 is fixed on the sound-absorbing bracket 23 by squeezing the disc 26, so that the sound-absorbing panels 11 of different thicknesses can be installed between the two groups of sound-absorbing brackets 23.

[0032] Furthermore, the baffle 3 is in a "T" shape, and a "T"-shaped groove is provided on the surface of the sound-absorbing bracket 23. The baffle 3 slides on the "T"-shaped groove of the sound-absorbing bracket 23. The slots on both sides of the sound-absorbing bracket 23 are composed of the sound-absorbing bracket 23 and the baffle 3. When the baffle 3 slides out from the sound-absorbing bracket 23, the slots of the sound-absorbing bracket 23 disappear, thereby facilitating the placement of the sound-absorbing panel 11 at the original slot position of the sound-absorbing bracket 23. When the sound-absorbing bracket 23 is slid in again, the sound-absorbing panel 11 is already at the slot position between the sound-absorbing bracket 23 and the baffle 3. There is no need to place the sound-absorbing panel 11 on the slot from the top of the sound-absorbing bracket 23, which facilitates installation.

[0033] Furthermore, a wire groove is opened on the surface of the fixing block 31, and the elastic force of the spring 32 acts on the limit block 33. The limit block 33 limits the position of the baffle 3 on the sound-absorbing bracket 23. The limit block 33 also limits the two groups of baffles 3, preventing the baffle 3 from sliding from the top of the sound-absorbing bracket 23, thereby ensuring that the slot of the sound-absorbing bracket 23 will not disappear.

[0034] Working principle: The moving block 21 slides on the guide rod 2 to change the position of the moving block 21 on the base plate 1, thereby changing the distance interval of the sound-absorbing bracket 23 on the base plate 1. The first bolt 22 rotates on the threaded hole of the moving block 21, and then the first bolt 22 passes through the circular hole of the guide rod 2, so that the moving block 21 and the sound-absorbing bracket 23 are fixed on the upper surface of the base plate 1. The two groups of sound-absorbing brackets 23 can adapt to sound-absorbing panels 11 of different lengths. At the same time, the second bolt 25 rotates on the nut 24, so that the disc 26 moves on the sound-absorbing bracket 23 to be squeezed on the sound-absorbing panel 11, so that the sound-absorbing panel 11 is squeezed and fixed on the sound-absorbing bracket 23. Sound-absorbing panels 11 of different thicknesses can be fixedly installed on the two groups of sound-absorbing brackets 23, so that sound-absorbing panels 11 of different specifications can be fixedly installed on the sound-absorbing bracket 23.

[0035] The limiting block 33 is pulled at the top of the sound absorbing bracket 23 to slide the baffle 3 out of the sound absorbing bracket 23, and then the sound absorbing panel 11 is placed on the surface of the sound absorbing bracket 23 from the side of the sound absorbing bracket 23, and then the baffle 3 is slid to the original position, and the limiting block 33 is released. Under the elastic force of the spring 32, the limiting block 33 slides to the top of the baffle 3, limiting the baffle 3 from sliding out of the sound absorbing bracket 23, so that the sound absorbing panel 11 does not need to be installed from the top of the sound absorbing bracket 23, but only needs to be installed from the side, thereby reducing the difficulty of installing the sound absorbing panel 11.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
