[0024] See also Figure 1-5The utility model provides a technical solution: a municipal deceleration ridge for preventing deformation, characterized in that it comprises an embedded shell 1, the top of the embedded shell 1 is provided with four limiting holes 2, the limiting holes 2 are movably embedded with limiting rods 3, the top of the limiting rods 3 is fixedly connected with a lifting plate 4, two cylinders 5 are arranged inside the embedded shell 1, and the output shaft of the cylinder 5 is linked with a pressure-bearing top block 6, the inside of the embedded shell 1 is rotatably connected with a first pressure-bearing rod 7 near the bottom, the outer surface of the first pressure-bearing rod 7 is fixedly sleeved with a first sleeve 8, the top of the outer surface of the first sleeve 8 is arranged at the bottom of the pressure-bearing top block 6, the bottom of the lifting plate 4 is fixedly connected with two pressure plates 9, and the bottom of the pressure plate 9 is fixedly connected with a plurality of connecting rods 10, under the connecting action of the connecting rods 10 and the limiting action of the limiting holes 2 on the limiting rods 3, the lifting plate 4 and the pressure plate 9 will be lifted up at the same time.

[0025] like Figure 1-5 As shown, the two connecting rods 10 are internally rotatably connected with the second pressure-bearing rod 11, and the outer surface of the second pressure-bearing rod 11 is fixedly sleeved with a second sleeve 12. The outer surface of the second sleeve 12 is arranged on the top of the pressure-bearing top block 6, and the second sleeve 12 and the second pressure-bearing rod 11 will roll and move upward along the inclined surface.

[0026] like Figure 1-5 As shown, a wear-resistant layer 13 is fixedly connected to the top of the lifting plate 4, and a plurality of reinforcing ribs 14 are fixedly embedded inside the wear-resistant layer 13. The reinforcing ribs 14 are used to prevent the deceleration ridge from being deformed under pressure.

[0027] like Figure 1-5 As shown, two side plates 15 are fixedly connected to the outer side of the lifting plate 4, and a plurality of anti-skid strips 16 are fixedly connected to the outer side of the side plates 15, and the anti-skid strips 16 prevent the vehicle from slipping when going up the ridge.

[0028] like Figure 1-5 As shown, two embedded grooves 17 are provided on the top of the embedded shell 1, and the outer surface of the side plate 15 is arranged inside the embedded groove 17. The side plate 15 on the side of the lifting plate 4 is lifted and lowered inside the embedded groove 17, so that the vehicle can go up the ridge without any sense of frustration, thereby protecting the tires.

[0029] like Figure 1-5 As shown, the material used for the wear-resistant layer 13 is solidified resin, and the material used for the reinforcing rib 14 is HRB400 steel bar. The solidified resin material has high wear resistance and weather resistance and is suitable for long-term outdoor use.
