[0025] Example

[0026] like Figure 1-4As shown, the metal sound barrier unit plate suitable for rail transit proposed by the utility model comprises a pair of support frames 1 and a plurality of linearly arranged plate bodies 2 installed in the middle of the support frames 1, the support frames 1 are provided with sliding slots 11 for the slot plates 3 at the ends of the plate bodies 2 to be movably inserted, the bottom ends of the support frames 1 are fixedly connected with mounting base blocks 12, the mounting base blocks 12 are provided with a plurality of bolt holes for mounting the mounting base blocks 12 on the ground, the plate bodies 2 are fixedly connected with a pair of support blocks 25 for supporting the rotation of the threaded rods 24, the support blocks 25 can provide support for the threaded rods 24, enhance the stability and load-bearing capacity of the threaded rods 24, and ensure that the threaded rods 24 will not be unstable or collapsed due to external forces. It also includes: a telescopic mechanism installed at both ends of the plate bodies 2 for disengaging from the middle of the support frames 1 after opening; a transmission mechanism for enabling the slot plates 3 at the ends of the plate bodies 2 to be quickly disassembled and assembled in the middle of the support frames 1.

[0027] Further, the transmission mechanism includes a hexagon socket bolt 21 rotatably connected to the middle of the plate body 2, the hexagon socket bolt 21 is fixedly connected to a first bevel gear 22 at one end inside the plate body 2, a pair of second bevel gears 23 meshingly connected to the first bevel gear 22 are provided inside the plate body 2, the first bevel gear 22 and the second bevel gear 23 are both bevel gears, and bevel gears are a common type of gear, the gear tooth surface is conical, and are used as mechanical elements for transmitting power and torque. Bevel gears are usually composed of two crossed bevel gears, which transmit power through the meshing of the tooth surfaces and can realize the cross or intersection transmission of the axis. The second bevel gear 23 is fixedly connected to a threaded rod 24, and the end of the threaded rod 24 away from the second bevel gear 23 is fixedly connected to an anti-slip block 27 for preventing the connection push block 26 from slipping out, and a pair of connection push blocks 26 spirally connected to the second bevel gear 23 are slidably provided inside the plate body 2.

[0028] Furthermore, the telescopic mechanism includes a pair of slot plates 3 slidably connected to the two ends of the plate body 2, and a transverse slider 33 is fixedly connected to the middle of the slot plate 3. The function of the transverse slider 33 is to make the slot plate 3 slide along the plate body 2 without deviating from the plate body 2. Both ends of the plate body 2 are provided with a moving slide 28 for the transverse slider 33 to slide. A stopper plate 34 is fixedly connected to the transverse slider 33. The function of the stopper plate 34 is to block the moving slide 28 at both ends of the plate body 2 to avoid affecting the sound insulation of the plate body 2. The end of the stopper plate 34 away from the transverse slider 33 is fixedly connected to a limit stopper plate 31. The function of the limit stopper plate 31 is to make the slot plate 3 slide along the plate body 2 without deviating from the plate body 2. The upper and lower ends of the limit stopper plate 31 are provided with balls 32. The function of the balls 32 is to reduce the friction resistance by rolling, thereby making the limit stopper plate 31 slide more effortlessly and smoothly in the plate body 2. The limiting abutment plate 31 is fixedly connected to an end of the corresponding connecting push block 26 away from the threaded rod 24 .

[0029] In this embodiment, when the metal sound barrier unit board of rail transit is needed, Figure 1 As shown, when replacing any one of the plates 2 in the middle of the support frame 1, first fix the plate 2 on the top of the plate 2 to be replaced to prevent the plate 2 on the top from sliding downward along the sliding slot 11 under the action of gravity after the replaced plate 2 is taken out. After that, it is only necessary to use a tool to rotate the hexagon socket bolt 21 on the plate 2. After the hexagon socket bolt 21 rotates, it drives the first bevel gear 22 to rotate. Since the first bevel gear 22 is meshed with a pair of second bevel gears 23, the first bevel gear 22 drives the pair of second bevel gears 23 to rotate, and the second bevel gear 23 drives the corresponding threaded rod 24 to rotate inside the plate 2. And since the threaded rod 24 is spirally connected with the corresponding connecting push block 26, the pair of connecting push blocks 26 push the corresponding limit plate 31 to move in the direction of the hexagon socket bolt 21, and the limit plate 31 slides more smoothly inside the plate 2 through the balls 32 at the upper and lower ends. At the same time, the limiting abutment plate 31 drives the retaining slot plate 34, the horizontal slider 33 and a pair of slot plates 3 to disengage from the sliding slots 11 on the pair of support frames 1 at the same time. At this time, the new plate body 2 can be placed in the middle of the support frame 1, and then the slot plates 3 at both ends of the plate body 2 are slid away from the hexagon socket bolts 21, and the slot plates 3 will be inserted into the corresponding sliding slots 11 on the support frame 1. The above operation can be reversed and will not be repeated here.
