[0001] The utility model relates to the technical field of road and bridge engineering, in particular to a sound insulation screen. Background Art

[0002] At present, soundproof screens are a noise reduction tool. The principle is to reduce the generation of noise through the transmission path. When sound is transmitted, it encounters an obstruction, which will affect the transmission of sound waves. In addition to blocking sound waves, the soundproof screen has an attractive material inside that can also absorb a lot of sound waves. Soundproof screens are generally installed through anti-collision walls in places such as roads where noise reduction is required.

[0003] At present, the sound insulation screens are installed on the top surface of the crash barrier with bolts. Because the sound insulation screens are thin and high, this installation method requires the use of the hanger for a long time, so the installation efficiency is low and the cost is increased.

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1 - Figure 6 As shown, a soundproof screen includes a side wall 100, an embedded iron piece 200 is embedded on the upper side of the side wall 100, a mounting plate 300 is provided on the upper side of the embedded iron piece 200, and symmetrically distributed mounting mechanisms are provided on the left and right sides of the mounting plate 300, and the mounting mechanism includes an outer plate 401, and the outer plate 401 is fixedly connected to one end of the mounting plate 300, and mounting grooves 403 are opened on the left and right sides of the top of the embedded iron piece 200, and an inner plate 404 is provided in the mounting groove 403, and a sliding column 405 is provided on the side of the inner plate 404 close to each other, and the sliding column 405 is slidably connected to the embedded iron piece 200, a clamping component is provided between the inner plate 404 and the outer plate 401, a limiting component is provided on the inner plate 404, a fixing mechanism is provided at the bottom of the outer plate 401, and a soundproof mechanism is provided on the upper side of the mounting plate 300.

[0028] The outer plate 401 is used to install the one-way tooth 1 402, the mounting groove 403 is used to install the inner plate 404, the inner plate 404 is used to install the one-way tooth 2 410, the sliding column 405 is used to maintain the sliding connection between the inner plate 404 and the embedded iron part 200, the clamping assembly is used to clamp the outer plate 401 and the inner plate 404, and the limiting assembly is used to prevent the inner plate 404 from falling off.

[0029] The clamping assembly includes a one-way tooth 410 , which is fixedly connected to the outer side of the inner plate 404 . The inner side of the outer plate 401 is fixedly connected with a one-way tooth 402 . The one-way tooth 402 is clamped in one direction with the one-way tooth 410 .

[0030] The one-way tooth 1 402 and the one-way tooth 2 410 form a one-way clamping connection, so that when the one-way tooth 2 410 descends, the initial connection between the sound insulation mechanism and the embedded iron piece 200 is completed.

[0031] The clamping assembly further includes a lower inclined panel 409 , which is fixedly connected to the inner side of the inner panel 404 . An upper inclined panel 408 is provided on the inner side of the outer panel 401 , and the top end of the upper inclined panel 408 is fixedly connected to the mounting plate 300 .

[0032] When the upper inclined panel 408 descends, it presses against the lower inclined panel 409. Due to the inclined surface, the upper inclined panel 408 pushes the lower inclined panel 409 to move outward, thereby causing the one-way tooth 2 410 on the inner plate 404 to engage with the one-way tooth 1 402 on the one-way tooth 2 410.

[0033] The limiting assembly includes an inner plate groove 406 , which is opened on the outer side of the inner plate 404 . A guardrail 407 is arranged in the inner plate groove 406 , and both ends of the guardrail 407 are fixedly connected to the embedded iron piece 200 .

[0034] The guardrail 407 is embedded in the inner plate groove 406 to prevent the inner plate 404 from falling off.

[0035] The sound insulation mechanism comprises a column 501 , the bottom end of the column 501 is fixedly connected to the mounting plate 300 , and the front and rear sides of the column 501 are fixedly connected to a sound insulation screen body 502 .

[0036] The column 501 is used to install the sound insulation screen body 502, and the sound insulation screen body 502 is used for sound insulation.

[0037] The fixing mechanism includes two mounting ears 601 , the top ends of the mounting ears 601 are fixedly connected to the outer plate 401 , the bottom ends of the mounting ears 601 and the bottom ends of the side walls 100 are both provided with mounting holes 602 , and the mounting holes 602 are provided with a snap-in pin assembly.

[0038] The mounting ears 601 are used to define mounting holes 602 . The mounting holes 602 are used to connect the mounting ears 601 on the left and right sides, so that the two outer panels 401 are more tightly connected.

[0039] The snap-in pin assembly includes a threaded pin 603, the outer side of which is slidably connected to a pin sleeve 604, one end of the threaded pin 603 and one end of the pin sleeve 604 are hinged with a connecting rod 605, the two connecting rods 605 are hinged away from one end of the threaded pin 603, and the other end of the threaded pin 603 is threadedly connected to a threaded hexagonal head 606.

[0040] The threaded pin 603 is used for slidingly connecting the pin sleeve 604 and the threaded hexagonal head 606. When the threaded hexagonal head 606 rotates, the axial movement of the pin sleeve 604 is squeezed, so that the connecting rod 605 and the threaded hexagonal head 606 complete the locking of the mounting ears 601 on both sides.

[0041] Working principle:

[0042] Under the hoisting of the sling, the two upper inclined panels 408 are aligned with the gap between the inner plate 404 and the embedded iron parts 200. When the upper inclined panel 408 descends, it presses against the lower inclined panel 409. With the assistance of the inclined surface of the lower inclined panel 409, the inner plate 404 is pushed outward, so that the one-way tooth 2 410 is engaged with the one-way tooth 1 402. Finally, as the height of the sling descends, the engagement becomes tighter and tighter. After the upper inclined panel 408 is in place, it can leave the sling, and the preliminary installation is now completed.

[0043] The threaded pin 603 is passed through the mounting hole 602. The mounting hole 602 on one side is clamped by the connecting rod 605, and the mounting hole 602 on the other side is clamped by the threaded hexagonal head 606. As the threaded hexagonal head 606 rotates, the pin sleeve 604 is pushed to move horizontally, so that the connecting rod 605 is gradually expanded, and the fixation of the two mounting ears 601 is completed.

[0044] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
