The technical problem is solved by the following technical scheme:
a deceleration strip comprises a plurality of deceleration blocks, wherein each deceleration block comprises a first deceleration part and a second deceleration part, the first deceleration part is fixedly arranged on the ground through a stud, and the second deceleration part is fixedly arranged at the top end of the first deceleration part; a plurality of elastic pieces are arranged in the second speed reducing part.
The utility model provides a deceleration strip with same height as the original deceleration strip, including first speed reduction portion and second speed reduction portion, wherein first speed reduction portion is used for connecting ground, and second speed reduction portion is the elastic component, and when the vehicle passes through fast, because the time that the vehicle passes through is less than the time that the elastic component atress reaches the compression, so the height that the deceleration strip descends is less, plays the effect of reminding the driving vehicle to slow down, and because the deceleration strip height descends, also can alleviate the damage to the shock absorber; when a vehicle finds the deceleration strip and passes through the deceleration strip at a low speed, the time for the vehicle to pass through is longer than the time for the elastic part to be stressed to be compressed, so that the descending height of the deceleration strip is larger, the effect of decelerating the driven vehicle is achieved, and meanwhile, the damage to the shock absorber can be better reduced.
Optionally, the first decelerating part comprises a rubber sleeve with a cavity, the middle part of the cavity is provided with a weight increasing block, and the cavity outside the weight increasing block is filled with filler.
Optionally, the second decelerating portion includes a rubber sleeve with a cavity, elastic members are arranged in the cavity and distributed at equal intervals, and the cavity outside the elastic members is filled with filler.
Optionally, the filler is concrete.
Optionally, the filler is fine sand.
Optionally, two stud bolts are installed respectively at the left and right ends of the weight increasing block and are used for fixedly connecting the first speed reducing part with the ground.
Optionally, the stud includes fixed nut and the movable nut of threaded connection at the threaded column lower extreme that the fixed setting is on the threaded column top, be equipped with the screw hole that matches and join in marriage with the threaded column on the weight increasing piece.
Optionally, the elastic member is a counter wave spring.
The utility model discloses can reach following effect:
the utility model provides a deceleration strip, including first speed reduction portion and second speed reduction portion, wherein first speed reduction portion is used for connecting ground, and second speed reduction portion is the elastic component, and when the vehicle passes through fast, because the time that the vehicle passes through is less than the time that the elastic component atress reaches the compression, so the height that the deceleration strip descends is less, plays and reminds the effect of driving the vehicle and slowing down, and because the deceleration strip height descends, also can alleviate the damage to the shock absorber; when a vehicle finds the deceleration strip and passes through the deceleration strip at a low speed, the time for the vehicle to pass through is longer than the time for the elastic part to be stressed to be compressed, so that the descending height of the deceleration strip is larger, the effect of decelerating the driven vehicle is achieved, and the damage to the shock absorber can be better reduced; the shock absorber has the advantages of reducing accident rate and damage to the shock absorber, along with simple structure and convenient use.
