Mechanical-type automatic elevating deceleration strip

The invention discloses a mechanical-type automatic elevating deceleration strip which can achieve automobile deceleration according to the pavement speed limiting requirement, and belongs to the field of pavement deceleration strips. The mechanical-type automatic elevating deceleration strip comprises a driving mechanism, a detection and control mechanism and an execution and return mechanism. The mechanical-type automatic elevating deceleration strip is characterized in that when a traveling vehicle travels at a required speed on a speed-limiting road section, the state of the deceleration strip is changed from a raised state to a smooth state, and the vehicle can pass the road section without barriers; when the vehicle does not travel at a required speed, the deceleration strip is in a raised state, and the vehicle passes the road section with barriers. The contradiction between the driving comfortableness and the vehicle speed solved.
