Description

Technical Field

[0001] The utility model relates to the field of road protection devices, in particular to a road safety buffer device. Background Art

[0002] Security can be understood as the abbreviation of "safety precautions". According to the Chinese dictionary, safety means no danger, no harm, and no accidents; prevention means preparation and alertness, and prevention means being prepared to deal with attacks or avoid being harmed, and alertness means prevention and protection. Traffic accidents are prone to occur on the road, so security buffer devices are needed.

[0003] Existing road safety buffer devices are not easy to deal with the situation where multiple vehicles hit the same part, which may lead to reduced safety and adaptability of the device. The existing road safety buffer device has a relatively fixed structure and is not easy to disassemble and replace, which may lead to reduced work efficiency of workers.

[0004] Therefore, a road safety buffer device is proposed to address the above problems. Utility Model Content

[0005] In order to remedy the problems in the prior art, the utility model proposes a road safety buffer device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a road security buffer device described in the utility model includes a mounting plate, a shell is fixedly provided on the surface of the mounting plate near one side, a clamping column is rotatably connected inside the shell, a frame is fixedly connected to the bottom of the clamping column, a rotating shaft is rotatably connected inside the frame, a shell is fixedly provided on the outside of the rotating shaft, sand and gravel blocks are placed inside the shell, a base side is fixedly connected on the inner side of the frame, one end of a support rod is rotatably connected inside the base, a slide groove is fixedly provided on the front side of the mounting plate, and a support column is fixedly connected to the rear side of the mounting plate.

[0007] Preferably, a bolt is provided through the surface of the housing, and the surface of the bolt fits with the surface of the clamping column.

[0008] Preferably, three shells are rotatably connected inside the frame, and reflective stickers are evenly distributed on the surfaces of the shells at equal distances.

[0009] Preferably, the other end of the support rod is slidably connected to the inside of the slide slot, the inner wall of the slide slot is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the other end of the support rod.

[0013] 1. The utility model disperses the initial impact force through the friction between the sand and stone blocks in the shell. Since the rotating shaft is rotatably connected to the frame, the shell rotates to guide the vehicle to continue to slide forward. When the vehicle leaves a device surface, the two ends of the spring pull the inner wall of the slide groove and the support rod to make the support rod slide to the right, which is convenient for the frame to reset. In response to the situation where multiple vehicles may hit the same part, the safety and adaptability of the device are improved;

[0014] 2. The utility model realizes the function of limiting the clamping column through the structural design of the bolt penetrating the shell. The structure is simple and convenient for disassembly and replacement, which reduces the maintenance cost of the device. The device is installed in a suitable workplace through rivets and the base plate, and the stability between multiple devices is improved by engaging the steel bar with the perforated holes on the surface of the adjacent base plates.
