Novel pressure-reducing square speed bump

Abstract

The invention discloses a novel pressure-reducing square speed bump, including a rectangular belt, the bottom of the rectangular belt is provided with a through groove, a fixed plate is fixedly installed inside the through groove, the inner wall of the through groove is fixedly connected with a fixed column, hinge shafts are fixedly installed on both sides of the fixed column, one side of each hinge shaft is hinged to a hinge rotary rod, one end of each hinge rotary rod is fixedly connected with a hinge seat, one side of each hinge seat is welded with a first connecting rod, one end of each first connecting rod is welded with a movable connecting plate, one end of each movable connecting plate is fixedly connected with a decompression spring, one end of each decompression spring is fixedlyconnected with a fixed block, and the bottoms of the fixed blocks are fixedly connected with the upper surface of the fixed plate. By arranging the rectangular belt, the contact area with the wheel is increased, and the weighing pressure of the speed bump is reduced; pressure on the rectangular belt can be further reduced by arranging the fixed column, the hinge shafts, the hinge rotary rods, thehinge seats, the first connecting rods, the decompression springs and the fixed blocks, so that the rectangular belt can bear the weight of a large vehicle.

Description

technical field [0001] The invention relates to the technical field of deceleration belts, in particular to a novel decompression square deceleration belt. Background technique [0002] Speed ​​bumps, also called speed bumps, are traffic facilities installed on highways to slow down passing vehicles. The shape is generally strip-shaped, and also dot-shaped; the material is mainly rubber, and there are also metal; generally yellow and black are used to attract visual attention, and the road surface is slightly arched to achieve the purpose of vehicle deceleration. It is generally installed on highway crossings, industrial and mining enterprises, schools, residential quarters, etc., where vehicles need to slow down and where traffic accidents are likely to occur. It is a new type of special traffic safety setting for reducing the speed of motor vehicles and non-motor vehicles. [0003] However, the existing speed bumps are generally arranged in an arched shape, which leads to...
