Abstract

The invention relates to a speed reduction device. The device comprises a base, a first slope, a first groove and a second slope are sequentially arranged on the base from one end to the other end. The two slopes are inclined towards the first groove; a first spring is arranged in the first groove; a first sliding block capable of moving in the first groove is supported on the first spring, a second groove is further formed in the base and located between the first groove and the second slope, a second spring is arranged in the second groove, and a second sliding block capable of moving in thesecond groove is supported on the second spring. The second sliding block capable of moving up and down is additionally arranged in the speed reducing device, so that the second sliding block moves downwards to form a height difference with the first sliding block to prevent the vehicle from running reversely when the vehicle is reversed.

Description

technical field [0001] The invention relates to the field of deceleration belts, in particular to a deceleration device. Background technique [0002] Patent CN109208496A discloses an anti-reverse speed bump. In this patent, the base has two slopes on the left and right, and a through groove is arranged in the middle of the base. The inclined one-way plate can move up and down in the through groove. When the vehicle is driving from left to right, the The one-way plate is depressed to prevent the vehicle from pitching. When no vehicle presses on the one-way plate, the spring will lift the one-way plate, so that there is a height difference between the right end of the one-way plate and the slope on the right side of the base, thereby preventing the vehicle from driving from right to left and realizing the anti-reverse effect. In this patent, the inclination of the one-way plate can be adjusted, so that the height difference can be adjusted. However, if the height difference...
