[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] like Figure 1-4 As shown, the utility model provides an improved guardrail plate, including two horizontal plates 1 and two columns 2, a corrugated plate 101 is arranged between the two horizontal plates 1, a buffer mechanism 3 is arranged on the outer surface of the column 2, the buffer mechanism 3 includes an extrusion block 301 and a base 304, two ends of the extrusion block 301 are rotatably connected to two rotating rods 302, a connecting rod 303 is fixedly arranged between the two rotating rods 302, a slide rail 305 is fixedly installed at both ends of the base 304, a damper 306 is fixedly installed on one end of the inner wall of the slide rail 305, one end of the damper 306 is fixedly connected to a ring 307, a groove 308 is opened at the top of the base 304, the other end of the extrusion block 301 is slidably connected to the inner wall of the groove 308, the outer surface of the connecting rod 303 is sleeved with the inner wall of the ring 307, and one end of the connecting rod 303 is slidably connected to the inner wall of the slide rail 305.

[0024] The following is a detailed description of the specific settings and functions of this embodiment. The two transverse plates 1 are fixedly installed by connecting the corrugated plates 101. The corrugated plates 101 are steel plates. The two ends of the corrugated plates 101 are welded to the two transverse plates 1. The corrugated plates 101 are wavy. When the corrugated plates 101 are subjected to impact force, the corrugated plates 101 will deform, and each corrugation will extend to both sides, and unload the impact force to the upper and lower ends, which can play a preliminary buffering effect. When the transverse plate 1 is hit, the transverse plate 1 will generate a force on the extrusion block 301, and the extrusion block 301 will be in the concave after being subjected to force. The extrusion block 301 slides in the groove 308, and the extrusion block 301 plays a guiding role in the groove 308. When the extrusion block 301 slides, the rotating rod 302 on the extrusion block 301 will rotate. When the two rotating rods 302 rotate, the connecting rod 303 between the two will be displaced in the horizontal direction. The connecting rod 303 will push the ring 307 to move and squeeze the damper 306. After the damper 306 is squeezed, the spring therein will produce elastic deformation and generate reverse thrust, which reacts to the rotating rod 302, thereby buffering the impact force received by the extrusion block 301. Example

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a sliding column 4 is fixedly installed at one end of the extrusion block 301, four sleeves 5 are fixedly installed at one end of one horizontal plate 1, and the inner walls of the four sleeves 5 are respectively slidably connected with one end of the four sliding columns 4. Two mounting sleeves 6 are provided on the outer surface of the column 2, and a fixing rod 7 is installed through the outer surface of the mounting sleeve 6. A nut 8 is threadedly connected to one end of the fixing rod 7, and one end of the fixing rod 7 is sleeved with the outer surface of the column 2. The mounting sleeve 6 is fixedly installed with the column 2 through the fixing rod 7 arranged thereon, and one end of the base 304 is fixedly installed with one end of the mounting sleeve 6.

[0026] The effect achieved by the entire embodiment is that, when replacing the two cross plates 1, the staff can touch the surface of the outer cross plate 1 with their hands and push it to one side until the sliding column 4 slides out of the sleeve 5 to complete the disassembly of the two cross plates 1, and then push the new two cross plates 1 in the opposite direction to make the sliding column 4 slide back into the sleeve 5. When replacing the buffer mechanism 3, the staff first loosens the nut 8 with a wrench or other tools, then pulls out the fixing rod 7, and finally takes out the mounting sleeve 6 connected to the buffer mechanism 3 to be replaced from the column 2. The operation is simple and reduces the maintenance burden of the staff.

[0027] The use method and working principle of this device: the two horizontal plates 1 are fixedly installed by connecting the corrugated plates 101. The corrugated plates 101 are steel plates. The two ends of the corrugated plates 101 are welded to the two horizontal plates 1. The corrugated plates 101 are wavy. When the corrugated plates 101 are subjected to impact force, the corrugated plates 101 will deform, and each corrugation will extend to both sides, and unload the impact force to the upper and lower ends, which can play a preliminary buffering effect. When the horizontal plate 1 is hit, the horizontal plate 1 will generate a force on the extrusion block 301. After the extrusion block 301 is subjected to force, it will slide in the groove 308. The extrusion block 301 plays a guiding role in the groove 308. When the extrusion block 301 slides, the rotating rod 302 on the extrusion block 301 will rotate. When the two rotating rods 302 rotate, the connecting rod 303 between the two will be displaced in the horizontal direction. The connecting rod 303 will push the ring 307 to move and squeeze the damper 306. After the damper 306 is squeezed, the spring therein will produce elastic deformation and generate a reverse thrust, which reacts on the rotating rod 302, thereby buffering the impact force received by the squeezing block 301; when replacing the two cross plates 1, the staff can touch the surface of the outer cross plate 1 with their hands and push it to one side until the sliding column 4 slides out of the sleeve 5 to complete the disassembly of the two cross plates 1, and then push the new two cross plates 1 in the opposite direction to make the sliding column 4 slide back into the sleeve 5. When replacing the buffer mechanism 3, the staff first uses a wrench or other tools to loosen the nut 8, then pull out the fixing rod 7, and finally remove the mounting sleeve 6 connected to the buffer mechanism 3 to be replaced from the column 2. The operation is simple and reduces the maintenance burden of the staff.
