[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] Embodiment: Refer to Figure 1 and Figure 2 A traffic guardrail as shown, including a support column 1. A hole is provided at the bottom of the support column 1. A first bolt 2 is threadedly connected inside the hole. A support footrest 3 is provided at the bottom of the first bolt 2. A universal wheel 4 is provided at the bottom of the support column 1. Place the device around the construction site, control the descent of the first bolt 2 of the support column. The support footrest 3 on the first bolt 2 touches the ground. Its four-sided force structure can enable the support column 1 to play a good supporting function. Control the first bolt 2 to rise, and the universal wheel 4 installed on the support column 1 touches the ground, which can achieve the purpose of pushing the support column 1 to move. Assembly seats 5 are provided on both sides of the support column 1. A pin column 6 is inserted inside the assembly seat 5. The assembly seat 5 is movably installed with a rotating frame 7 through the pin column 6. A cross beam frame 8 is fixedly connected to one side of the rotating frame 7. When deploying or retracting the device, by rotating the rotating frame 7, a 180-degree rotation of the cross beam frame 8 connected to the rotating frame 7 is achieved, which is convenient for setting the orientation when the device is deployed or the overall movement when retracting. After the support column 1 is propped up, use the flexible rotation of the rotating frame 7 to rotate the side of the cross beam frame 8 equipped with the buffer mechanism 13 towards the oncoming vehicle. Finally, use the support frame 1 and the cross beam frame 8 to enclose the road construction site to prevent pedestrians or passing vehicles from accidentally entering the device, causing potential hazards. A warning light 9 is provided at the top of the support column 1 to provide night warning. A support frame storage groove is provided on another surface of the support column 1. A support frame storage groove hole is provided at the bottom of the support frame storage groove. A support frame 14 is stored inside the support frame storage groove. A bolt 15 is provided on another surface of the support column 1. The bolt 15 retracts the support frame 14 into the support frame storage groove. The other end of the support frame 14 is equipped with a support frame sleeve 17. The support frame sleeve 17 is provided with a threaded hole. An expansion screw 18 is threadedly connected inside the threaded hole. When the device is arranged, the bolt 155 can be opened, put one end of the support frame 14 on the support frame sleeve 17, support the support frame 14 on the ground, and drive the expansion screw 18 into the ground through the support frame sleeve 17 to provide a sufficient buffer foundation for the device.
[0021] As a preferred implementation manner in this embodiment, as Figure 1 and Figure 3As shown in the figure, there is a safety airbag groove 10 inside the crossbeam frame 8. Threaded holes are provided on the outer surfaces on both sides of the safety airbag groove 10. A second bolt is movably connected inside the threaded holes. A safety airbag tube 11 is provided inside the safety airbag groove 10. A safety airbag 12 is provided on one side of the safety airbag tube 11. The safety airbag tube 11 and the safety airbag groove 10 are connected by the second bolt. Threaded holes are provided on the rear side of the crossbeam frame 8, and a third bolt is threadedly connected to the threaded holes. The safety airbag 12 provided on the crossbeam frame, when the first two buffer mechanisms of the buffer mechanism exert their maximum energy efficiency, triggers the striker to impact the safety airbag, providing the final buffer capacity for the device. The setting of the safety airbag groove 10 facilitates the replacement of the used safety airbag for the device. The third bolt provided on the rear side of the crossbeam frame 8 facilitates the assembly and disassembly of the buffer mechanism 13.
[0022] As Figure 1 and Figure 4As shown in the figure, in this embodiment, the crossbeam frame 8 is threadedly connected to a buffer mechanism 13 through a third bolt. The buffer mechanism 13 includes a buffer plate 1301. On one side of the buffer plate 1301, there is a buffer spring 1302. One end of the buffer spring 1302 is fixedly connected to a first resistance plate 1303. On one side of the first resistance plate 1303, there is a first spring base 1304. A hole is opened at the bottom of the first spring base 1304, and a first assembly rod 1305 is inserted into the hole. A first spring block 1306 and a first resistance spring 1307 are sleeved on the surface of the first assembly rod 1305 from top to bottom. A first circular groove 1308 is opened on one side of the first spring block 1306, and a first ball rod 1309 is movably installed inside the first circular groove 1308. One end of the first ball rod 1309 is sleeved with a first counter impact plate 1310. A pressure spring 1311 is fixedly installed on one side of the first counter impact plate 1310. One end of the pressure spring 1311 is fixedly installed with a second counter impact plate 1312. A second circular groove 1313 is opened at the top of the second counter impact plate 1312, and a second ball rod 1314 is movably installed inside the second circular groove 1313. One end of the second ball rod 1314 is sleeved with a second spring block 1315. A second assembly rod 1316 is inserted into the second spring block 1315. A second resistance spring 1317 is provided above the second spring block 1315. The top end of the second assembly rod 1316 is inserted into a second spring base 1318. The second resistance spring 1317 and the second spring block 1315 are sleeved on the surface of the second assembly rod 1316 from top to bottom. A second resistance plate 1319 is fixedly connected to one side of the second spring base 1318. A reflective sheet 1320 is provided on the other side of the buffer plate 1301. When the buffer plate 1301 is impacted for the first time, kinetic energy is transmitted to the buffer spring 1302. The buffer spring 1302 is connected to the first resistance plate 1303. The kinetic energy first performs first energy release between the first buffer network composed of the buffer plate 1301, the buffer spring 1302, and the first resistance plate 1303, and then the kinetic energy is transmitted to the second buffer network between the first resistance plate 1303 and the second resistance plate 1319. The kinetic energy impetus causes the first ball rod 1309 to transmit pressure to the first counter impact plate 1310 through the first circular groove 1308. The first counter impact plate 1310 carries the pressure and conducts it to the pressure spring 1311 and the second counter impact plate 1312. The kinetic energy performs two-way force conduction and counter impact here. The first counter impact plate 1310 and the second counter impact plate 1312 transmit the kinetic energy to the first ball rod 1309 and the second ball rod 1314 through the first circular groove 1308 and the second circular groove 1313. The first ball rod 1309 and the second ball rod 1314 transmit the kinetic energy to the first spring block 1306 and the second spring block 1315 through the first circular groove 1308 and the second circular groove 1313. The first spring block 1306 and the second spring block 1315 move on the first assembly rod 1305 and the second assembly rod 1316 under the influence of kinetic energy. The kinetic energy is transmitted to the first resistance spring 1307 and the second resistance spring 1317 through the first spring block 1306 and the second spring block 1315,Kinetic energy is released twice between the first resistance spring 1307 and the second resistance spring 1317 and the spring assembly composed of the first spring base 1304 and the second spring base 1318, and the energy returns again. For this reason, the second buffer net will deform, causing the striker on the second impact plate 1312 to move backward. When the second buffer net absorbs kinetic energy to the maximum extent, the striker hits the airbag, triggering the last third buffer net.
