Description

Technical Field

[0001] The utility model relates to the technical field of road speed bumps, in particular to a road assembled speed bump. Background Art

[0002] Speed ​​​​bumps are traffic facilities installed on roads to slow down passing vehicles. Speed ​​​​bumps make the road surface slightly arched to achieve the purpose of slowing down vehicles. Speed ​​​​bumps are generally set up at intersections, schools, residential area entrances and other sections where vehicles need to slow down and sections that are prone to traffic accidents.

[0003] In the prior art, such as the Chinese publication number CN219908648U, the utility model discloses a speed bump, which relates to the technical field of speed bumps, including a mounting base plate, the top of which is mounted with an elastic steel plate in an arc-shaped structure, and the mounting base plate on both sides of the elastic steel plate is provided with long strip-shaped sliding holes. The present application adopts the coordination arrangement between the mounting base plate, the sliding hole, the elastic steel plate, the screw rod and the elastic reset device, and when the vehicle rolls over the edge of the elastic steel plate and applies a horizontal force to the overall speed bump structure, the mounting base plate can move horizontally on the road surface through the sliding hole. Since the length of the sliding hole is much larger than the diameter of the screw rod, the overall speed bump structure can be prevented from forming a shear force between the inner wall of the sliding hole and the screw rod during movement, and the problem that the connection between the fixed rod and the road surface of the existing speed bump is easily broken under the lateral shear force during the rolling process of the vehicle is avoided as much as possible, resulting in the speed bump falling off from the road surface, which greatly affects the service life of the speed bump.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantages of the above scheme are that there is a lack of structure for connecting multiple assembly frames by plugging in the plug-in blocks and plug-in slots at both ends, and there is a lack of structure for fastening multiple speed bump bodies to the surfaces of multiple assembly frames by slide rails and reinforcement bolts, which makes it impossible for the device to conveniently assemble and disassemble the speed bumps according to actual road traffic conditions. There is a lack of structure for injecting non-Newtonian fluid material into the through holes on the inner wall of the speed bumps and sealing them with sealing covers, which makes it impossible for the device to effectively slow down high-speed cars and reduce the bumps of low-speed cars when passing through speed bumps. The effect and use experience of the speed bumps are reduced, and the device cannot adjust the vertical height of the assembly frame and the speed bump body according to actual road traffic conditions.
