Wherein, the aperture of the perforating hole of link rod 9 is the diameter third of deceleration strip main part 7 inner chamber for when high-speed wheel extrusion deceleration strip main part 7, because the wheel is short with deceleration strip main part 7 contact time, in very short time, because the aperture setting of perforating hole, make the gas in smooth chamber 8 can not shift to in the air cavity 10 in a large number, make deceleration strip main part 7 move down the degree not high, make deceleration strip main part 7 still can make the vehicle that drives at a high speed have certain shock, and then realize reminding the function that the vehicle slowed down.

Wherein, the left side of the main body 1 is provided with a pressure plate cavity 2, the inside of the pressure plate cavity 2 is movably provided with a pressure plate 3, the pressure plate cavity 2 is provided with gas at the lower position of the pressure plate 3, the inside of the main body 1 is provided with a gas guide tube 5, one end of the gas guide tube 5 is communicated with the pressure plate cavity 2, the other end of the gas guide tube 5 is communicated with the upper position of the gas cavity 10, when a vehicle running at low speed approaches the deceleration strip, the wheel of the vehicle firstly contacts with the pressure plate 3, the pressure plate 3 is extruded and then moves downwards, in the process of moving downwards the pressure plate 3, the gas in the pressure plate cavity 2 is extruded into the gas cavity 10 through the gas guide tube 5, the gas entering the gas cavity 10 pushes the through rod 9 to move downwards, so that the through rod 9 drives the main body 7 of the deceleration strip to move downwards to a position slightly higher than the ground surface, the vehicle with a low chassis can smoothly pass through the deceleration strip, and the deceleration strip is prevented from causing abrasion to the ground plate of the vehicle with the low chassis, simultaneously because deceleration strip main part 7 moves down to current position for when slow-speed vehicle contact deceleration strip main part 7, only can produce the vertical displacement of slight degree, and then reduce the sense of vibration that this displacement caused the vehicle, reduce the damage of sense of vibration to the vehicle bumper shock absorber.

The lower end port of the through hole is arranged at the bottom of the through rod 9, when a vehicle running at low speed contacts the deceleration strip main body 7 slightly higher than the ground surface, the vehicle extrudes the deceleration strip main body 7 to further move downwards, and the gas in the inner cavity of the deceleration strip main body is extruded into the air cavity 10 through the through hole of the through rod 9, because the lower end port of the through hole is arranged at the bottom of the through rod 9, the gas exhausted from the bottom of the through rod 9 is continuously accumulated at the bottom of the air cavity 10, and then the through rod 9 is pushed to move upwards through the gradually accumulated gas, the through rod 9 which moves upwards contacts the deceleration strip main body 7, and then a vertical upward supporting force is applied to the deceleration strip main body 7, so that the deceleration strip main body 7 is prevented from excessively moving downwards to generate ground depression, and when the vehicle passes through the depression, the vehicle generates vertical displacement, causes vibration and further damages a shock absorber of the vehicle.

The distance between the pressure plate 3 and the speed bump main body 7 is half of the length of a running vehicle.

The use method (working principle) of the invention is as follows:

when the deceleration strip works, the deceleration strip is firstly embedded into a required position, when a vehicle drives through the deceleration strip at high speed, the contact time between the wheels and the pressing plate 3 is extremely short, so that the pressing plate 3 does not displace, then the wheels contact the deceleration strip main body 7, the deceleration strip main body 7 is extruded, and then the deceleration strip main body moves downwards and extrudes the elastic part II 11, when the deceleration strip main body 7 moves downwards, the gas in the sliding cavity 8 can push the through rod 9 to move downwards, because the deceleration strip main body 7 and the through rod 9 are separately arranged, and the through rod 9 and the gas cavity 10 are in sealed sliding connection, when the through rod 9 moves downwards, negative pressure suction force can be generated between the through rod 9 and the gas cavity 10, so that the downward moving speed of the through rod 9 is smaller than the downward moving speed of the deceleration strip main body 7, and further, the gas in the sliding cavity 8 can be extruded in the downward moving process of the deceleration strip main body 7, and the gas can be discharged into the gas cavity 10 through the through holes of the through rod 9, therefore, the impact energy of the wheels to the speed bump main body 7 is transferred through the transfer of the gas, so that a buffering effect is achieved, meanwhile, as the contact time between the wheels of the high-speed running vehicle and the speed bump main body 7 is short, and in a short time, due to the arrangement of the aperture of the through hole, the gas in the sliding cavity 8 is not transferred into the gas cavity 10 in a large amount, so that the downward moving degree of the speed bump main body 7 is not high, the speed bump main body 7 still enables the high-speed running vehicle to have a certain vibration feeling, so that the function of reminding the vehicle of decelerating is achieved, then, as the vehicle runs over, the speed bump main body 7 is driven by the elastic force of the elastic piece II 11 to reset, the through rod 9 resets accordingly, the gas in the gas cavity 10 is also pumped back into the sliding cavity 8 along with the resetting action, when the low-speed vehicle approaches the device, the wheels of the low-speed vehicle firstly contact with the pressure plate 3, and the pressure plate 3 is squeezed, then the elastic piece I4 is extruded and moves downwards, in the process that the pressing plate 3 moves downwards, the gas in the pressing plate cavity 2 is extruded into the upper area of the air cavity 10 through the gas guide pipe 5, the gas entering the upper area of the air cavity 10 pushes the through rod 9 to move downwards, so that the through rod 9 drives the speed bump main body 7 to move downwards to a position slightly higher than the ground surface, then, along with the continuous running of the vehicle, when the wheel of the low-speed running vehicle contacts the speed bump main body 7 slightly higher than the ground surface, the wheel extrudes the speed bump main body 7 to move downwards further, the gas in the inner cavity of the speed bump main body is extruded into the air cavity 10 through the through hole of the through rod 9, as the lower end port of the through hole is arranged at the bottom of the through rod 9, the gas discharged from the bottom of the through rod 9 is continuously accumulated at the bottom of the air cavity 10, the through rod 9 is pushed to move upwards through the gradually accumulated gas, the upward through rod 9 contacts the speed bump main body 7, and then exert a vertical ascending holding power to deceleration strip main part 7 to avoid deceleration strip main part 7 excessively to move down, after the vehicle drove, elastic component I4 drove clamp plate 3 and resets, and elastic component II 11 drove deceleration strip main part 7 and resets, makes the regional gas in air cavity 10 upper portion return to in the clamp plate chamber 2, makes the regional gas in air cavity 10 lower part return to in sliding chamber 8, and this is a duty cycle.
