[0030] 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.

[0031] like Figures 1 to 8 As shown, the utility model provides a sound barrier that can improve road safety, including:

[0032] A base 1, with upright poles 2 fixedly mounted on the left and right sides of the top of the base 1, the number of the upright poles 2 being two, the bottom ends of the two upright poles 2 being movably sleeved with lower barriers 3, the bottom end of the lower barrier 3 being movably connected to the top of the base 1;

[0033] A warning mechanism 4, which is arranged at the front end of the lower barrier 3;

[0034] A disassembly mechanism 5, which is arranged at the top of the front end of the lower barrier 3;

[0035] Among them, the warning mechanism 4 includes a reflective sign 401, which is movably installed in the middle of the bottom end of the lower barrier 3. Mounting frames 402 are fixedly installed on the left and right sides of the top of the reflective sign 401. The number of mounting frames 402 is two. The top ends of the two mounting frames 402 penetrate the lower barrier 3 and extend to the top of the outer surface of the lower barrier 3. The insides of the two mounting frames 402 are movably sleeved with card plates 403 respectively. The number of the card plates 403 is two. The two card plates 403 are movably sleeved on the left and right ends of the lower barrier 3 respectively. The front ends of the two card plates 403 are fixedly installed with first round blocks 404 respectively, and the first round blocks 404 will cause the card plates 403 to move.

[0036] When the first round block 404 is pushed, since the card plate 403 and the first round block 404 are fixedly connected, the two card plates 403 will move toward each other along the inner surface of the lower barrier 3 under the drive of the first round block 404, so that the card plate 403 and the mounting frame 402 are separated, and then the locking of the card plate 403 on the mounting frame 402 is released. The operator can quickly disassemble the reflective sign 401 by adjusting the position of the card plate 403, thereby facilitating the replacement of the reflective sign 401. The presence of the reflective sign 401 can serve as a warning to vehicles traveling on the road, thereby improving road safety.

[0037] Wherein, the disassembly mechanism 5 includes:

[0038] A fixed shaft 501, the number of the fixed shafts 501 is two, the two fixed shafts 501 are respectively fixedly installed on the left and right sides of the bottom end of the lower barrier 3, the outer surfaces of the two fixed shafts 501 are respectively movably sleeved with rotating rods 502, the number of the rotating rods 502 is two, the two rotating rods 502 are respectively movably sleeved at the left and right ends of the lower barrier 3, the top ends of the two rotating rods 502 are respectively movably connected to the bottom ends of the two clamping plates 403, the inner surfaces of the two rotating rods 502 are respectively movably sleeved with the inner surfaces of the two first round blocks 404, and a first spring 503 is fixedly installed between the two rotating rods 502;

[0039] The second round block 504, the number of the second round blocks 504 is two, the two second round blocks 504 are respectively movably sleeved on the inner surfaces of the top ends of the two rotating rods 502, the rear ends of the outer surfaces of the two second round blocks 504 are fixedly sleeved with connecting blocks 505, the connecting blocks 505 are movably sleeved on the inner surface of the lower barrier 3, and the top of the connecting block 505 is fixedly installed with a handle 506, and the handle 506 is movably sleeved on the top end inside the lower barrier 3.

[0040] When the handle 506 is pulled, the connecting block 505 will move upward with the second round block 504, so that the outer surface of the second round block 504 will generate a thrust on the inner surface of the rotating rod 502, pushing the rotating rod 502 to rotate around the fixed axis 501 and compress the first spring 503, so that the rotating rod 502 will generate a thrust on the first round block 404, pushing the first round block 404 to move.

[0041] The upper barrier 6 is movably mounted on the top of the lower barrier 3 , and the left and right ends of the upper barrier 6 are movably sleeved on the inner surfaces of the two upright poles 2 , respectively. A ventilation slot 7 is provided at the front end of the upper barrier 6 .

[0042] Due to the presence of the upper barrier 6 and the ventilation slots 7, the influence of wind pressure on the sound barrier will be reduced.

[0043] The left and right ends of the ventilation slot 7 are movably sleeved with vertical rods 8 , and the top of the vertical rod 8 is fixedly installed with a horizontal rod 9 , which is movably sleeved on the top of the ventilation slot 7 .

[0044] The vertical rod 8 is fixed to the upper barrier 6 by bolts, so that it is convenient to replace it.

[0045] Among them, the inside of the cross bar 9 is movably sleeved with a round rod 10, the middle part of the outer surface of the round rod 10 is fixedly sleeved with a connecting rod 11, the connecting rod 11 is movably sleeved inside the cross bar 9, and a rotating plate 12 is fixedly installed at the bottom end of the connecting rod 11, and the outer surface of the rotating plate 12 is movably connected to the outer surface of the vertical rod 8.

[0046] When the rotating plate 12 rotates, the round rod 10 will be driven to rotate together through the connecting rod 11.

[0047] The left and right ends of the cross bar 9 are respectively provided with arc grooves 13 , and a slider 14 is movably sleeved inside the arc groove 13 , and the bottom end of the slider 14 is fixedly connected to the top end of the round rod 10 .

[0048] The inner surface of the arc groove 13 and the outer surface of the slider 14 are both smooth, ensuring that the slider 14 will not get stuck when moving along the inside of the arc groove 13 .

[0049] Among them, the left and right ends of the slider 14 are respectively fixedly installed with second springs 15, the number of the second springs 15 is two, and the other ends of the two second springs 15 are respectively fixedly connected to the left and right ends inside the arc groove 13, and the second springs 15 will reset the slider 14.

[0050] When the slider 14 rotates, the second spring 15 will be compressed, and the slider 14 will be forced to return to its original position under the restoring action of the second spring 15 .

[0051] The working principle and use process of this utility model:

[0052] First, after the operator installs the sound barrier, he pulls the handle 506, so that the handle 506 drives the connecting block 505 and the second round block 504 to move upward, so that the outer surface of the second round block 504 generates a thrust on the inner surface of the top of the rotating rod 502, pushing the rotating rod 502 to rotate around the fixed axis 501 and compressing the first spring 503. At this time, the inner surface of the bottom end of the rotating rod 502 will generate a thrust on the outer surface of the first round block 404, pushing the two first round blocks 404 to move towards each other with the two clamping plates 403 respectively. Movement will cause the card plate 403 to be received in the lower barrier 3. Then the operator can insert the mounting frame 402 into the lower barrier 3 and release the handle 506. Under the restoring action of the first spring 503, the card plate 403 will return to its original position, thereby locking the mounting frame 402 and the reflective sign 401. Due to the presence of the reflective sign 401, the light of the vehicle will be reflected, thereby alerting the driver. The mutual cooperation of various mechanisms not only improves the safety of the road, but also makes the disassembly and installation of the reflective sign 401 more convenient, thereby improving the practicality of the sound barrier.

[0053] When the wind pressure is too high, the rotating plate 12 will rotate. At this time, the rotating plate 12 will rotate together with the round rod 10 through the connecting rod 11. Since the slider 14 is fixedly connected to the round rod 10, the slider 14 will also rotate, so that the slider 14 compresses the second spring 15. Under the restoring action of the second spring 15, when the wind pressure decreases, the slider 14 will be forced to return to its original position with the rotating plate 12. By setting the rotating plate 12, the slider 14 and the second spring 15, the resistance of the sound barrier to wind pressure will be enhanced without affecting the noise reduction effect of the sound barrier, thereby increasing the service life of the sound barrier.
