(2) The inside branch and the reed that have elasticity that set up of deceleration strip provide the effect that resets for the deformation of deceleration strip. When a vehicle passes through, the reed is pressed by the support rod to bend downwards, so that the bottom of the support rod is pressed into the corrugated pipe, the inclined angle of the support rod is changed, the guide effect is achieved on the deformation of the support rod, the middle of the support rod bends towards the center of the deceleration strip, and the auxiliary guide effect is achieved on the deformation of the support rod. If there is not reed and branch and not crooked to the center, when the vehicle was passed through, the branch on right side received pressure and produced the bellied deformation in upper right side, and in the long run, the branch on right side continuously received rolling of vehicle and produced more huge irreversible deformation, will influence the life of deceleration strip. And set up reed and branch middle part to the crooked structure in center, the vehicle is when passing through the deceleration strip right side, and the branch on right side will produce the deformation to the deceleration strip center, can not receive rolling of vehicle, guarantees the long-term normal use of deceleration strip. (3) The height adjusting device is arranged, so that the height of the speed bump can be adjusted, and the speed limiting requirements of various roads and road conditions in cities are met. (4) The casing embedding ground of deceleration strip bottom effectively resists the fore-and-aft direction's that the vehicle produced when passing through to the deceleration strip power, avoids the aversion and the damage of deceleration strip.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1-2, the municipal road safety deceleration strip of the embodiment comprises a shell 1, a rubber sheet 2, a sealing sheet 3, a support 4, a reed 5, a corrugated pipe 6, a height adjusting device 7 and a partition plate 8.
As shown in fig. 1-2, the housing 1 is embedded in the ground; the clapboard 8 is positioned above the shell 1, and the clapboard 8 is provided with a plurality of round through holes; the middle part epirelief of rubber 2, the edge of rubber 2 pastes with the edge of casing 1 mutually and accompanies gasket 3 between the two, and rubber 2 and casing 1 enclose into the airtight cavity of deceleration strip, are provided with non-Newtonian fluid in this cavity, and non-Newtonian fluid is located bellows 6 top. When a vehicle with a relatively high vehicle speed passes by, the rubber 2 tends to deform downward more, and the non-newtonian fluid gives the rubber 2 a relatively high force against such deformation, whereas when a vehicle with a relatively low vehicle speed passes by, the rubber 2 tends to deform downward less, and the non-newtonian fluid gives the rubber 2 a relatively low force against such deformation. Namely, the deceleration effect of the deceleration strip is more obvious when the vehicle speed is higher. The reed 5 is positioned in the sealed cavity of the deceleration strip, one end of the reed 5 is arranged at the top of the partition plate 8, and the other end of the reed 5 is arranged above the circular through hole in the partition plate 8 in a hanging manner; the supporting rod 4 one end support at the top of rubber skin 2 and the other end fix the free end at reed 5, when the vehicle passes through, reed 5 receives the pressure of supporting rod 4 and the downwarping makes the bottom of supporting rod 4 remove to the inside of bellows 6, and the angle that the branch 4 slopes obtains changing this moment, plays the guide effect for the deformation of branch 4. The corrugated pipe 6 is arranged in the shell 1, and the top end of the corrugated pipe 6 is connected with the edge of the circular through hole on the partition plate 8.
As shown in fig. 1-2, the height adjusting device 7 comprises an adjusting plate 71, a rotating shaft 72, a winding roller 73, an adjusting rope 74, a pulling rope 75, an adjusting knob 76 and a friction positioning ring 77; the adjusting plate 71 is positioned in the shell 1, the adjusting plate 71 is circular, and the adjusting plate 71 seals the bottom surface of the corrugated pipe 6; the rotating shaft 72 is arranged in the shell 1 and is positioned below the adjusting plate 71; the winding roller 73 is arranged on the rotating shaft 72; one end of the adjusting rope 74 is wound on the winding roller 73, and the other end is connected with the adjusting plate 71; one end of the pull rope 75 is connected with the adjusting plate 71, and the other end is connected with the top of the rubber sheet 2; the adjusting knob 76 is arranged at one end of the rotating shaft 72; friction holding ring 77 cup joint on pivot 72 and friction holding ring 77 passes through the support column to be fixed in the bottom of casing 1, friction holding ring 77 can increase the frictional force that receives when pivot 72 is rotatory, avoids pivot 72 to produce rotatoryly because of various uncontrollable external factors under the natural state.
As shown in fig. 1-2, two reeds 5 are symmetrically arranged on each circular through hole of the partition plate 8. The supporting rod 4 and the reed 5 are both elastic, and the supporting rod 4 is made of rubber. The middle part of the support rod 4 is bent towards the center of the speed bump. If not crooked to the center, when the vehicle passed through, the branch 4 on right side received pressure and produced the bellied deformation of upper right side, and long this in the past, the branch 4 on right side continuously receives rolling of vehicle and produce bigger irreversible deformation, will influence the life of deceleration strip. And set up to the crooked structure in center, the vehicle is when passing through the deceleration strip right side, and branch 4 on right side will produce the deformation to the deceleration strip center, can not receive rolling of vehicle, guarantee the long-term normal use of deceleration strip. The length of the suspended part of the spring 5 is three times of that of the part attached to the shell 1, so that the bendable part of the spring 5 is long enough to adapt to the deformation of the support rod 4. The pull cord 75 is inelastic and is in a taut state in a natural state, i.e., taut when no vehicle is passing.
When the speed bump is used, a user can firstly adjust the height of the speed bump according to the speed reduction requirement of a road: an adjusting wrench is used for twisting the adjusting knob 76 clockwise or anticlockwise, the adjusting knob drives the rotating shaft 72 to rotate, the adjusting rope 74 can be collected or paid out through rotation of the winding roller 73, and the top of the rubber sheet 2 can be lifted under the elastic action of the support rod 4 or lowered under the pulling force of the winding roller 73 due to the fact that the pull rope 75 is continuously tightened by the elastic force of the support rod 4. When the vehicle passes through, the symmetrically arranged support rods 4 have radians bent towards the center, deformation bent towards the center of the speed bump is generated, and the situation that the vehicle rolls for a long time to bend towards the outer side to generate irreversible deformation so as to influence the service life of the speed bump can be avoided. Due to the fact that the speed of the vehicle is different, the non-Newtonian fluid in the deceleration strip can exert different deceleration effects on the vehicle, and the higher the speed of the vehicle is, the more obvious the bumping effect is. The sealing sheet 3 can increase the tightness of the connection between the shell 1 and the rubber sheet 2, and prevent dust from entering the inside of the speed bump to influence the use performance of the speed bump.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the embodiments and descriptions given above are only illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the claims.
