[0002] Installing a deceleration device on the road surface can effectively prevent vehicles on the road from speeding, thereby improving the safety of vehicles when driving on the road.

[0003] After searching, a patent document with patent announcement number CN213571617U discloses a deceleration device for highway traffic safety construction, including a U-shaped plate, three slide grooves are provided on the bottom surface of the U-shaped plate, two sliders are respectively clamped in the three slide grooves, connecting columns are respectively provided on one side of the two sliders, and connecting sleeves are respectively provided on both sides of the slide grooves corresponding to the two connecting columns; support rods are respectively provided on the top of the two sliders, and support plates are provided on the top of the support rods; an arc plate is provided on the top of the support plate, a connecting groove is provided on the bottom of the arc plate, and a connecting block is provided on the top of the support plate corresponding to the connecting groove. The utility model installs the support plate on the top of the support rod, and when the support plate is compressed, the two support rods respectively push the two sliders, prompting the two sliders to move in opposite directions, so that the support plate moves downward, thereby buffering the vertical impact force; the connecting block on the support plate is clamped in the connecting groove of the arc plate, and when the arc plate is subjected to a lateral impact, the arc plate will move slightly on the support plate along the connecting groove, thereby buffering the lateral impact force.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The existing deceleration device for highway traffic safety construction, during use, blocks vehicles traveling on the road through the speed brake, thereby reducing the speed of the traveling vehicles, thereby improving the traffic safety of the vehicles when traveling. However, the existing deceleration device for highway traffic safety construction is not convenient for preventing vehicles from going in the opposite direction on the road, thereby reducing the traffic safety of the vehicles when traveling on the road;

[0006] 2. In the existing highway traffic safety construction deceleration device, the speed reducer provided during use effectively causes the moving vehicle to slow down, but the angle of the speed reducer is not easy to adjust, thereby reducing the functionality of the existing highway traffic safety construction deceleration device.

[0007] To this end, we provide a traffic safety deceleration device to solve the above-mentioned problems. Utility Model Content

[0008] The utility model aims to provide a deceleration device for traffic safety, which solves the problems that the existing deceleration device for highway traffic safety construction is not convenient for preventing vehicles from driving in the opposite direction and has a single functionality by arranging an anti-reverse component and an angle adjustment component.

[0012] The utility model is further configured that sound-absorbing cotton is arranged inside the through grooves arranged at equal intervals on the anti-retrograde plate.

[0013] The utility model is further configured such that the lower surface of the anti-retrograde plate is symmetrically connected to a damper through a hinge body, a shock absorbing spring is sleeved on a peripheral side wall of the damper, and the lower end of the damper is connected to a guide block through a hinge body.

[0014] The utility model is further configured that the guide block is slidably connected to the guide groove, and the connecting bolts symmetrically threaded on the guide block are connected to the base plate.

[0015] The utility model is further configured such that the slide groove is slidably connected to the slider, the end of the guide shaft penetrating the inside of the slider is connected to the inner wall of the groove, and the end of the telescopic spring sleeved on the peripheral side wall of the guide shaft is connected to the side wall of the slider.
