[0037] In one embodiment, a spring is sleeved on the outer side of the telescopic rod 410 .

[0038] A buffer block 440 is slidably connected to the inside of the column 100, and the right end of the buffer block 440 is connected to the inside of the column 100 through a spring. The left side of the buffer block 440 is passed through the outside of the column 100, and the upper and lower sides of the left side of the buffer block 440 are connected to the pull rope 450.

The right side of the connecting block 420 is detachably installed with a telescopic rod 410 by bolts, and a spring is sleeved on the outside of the telescopic rod 410. The right side of the telescopic rod 410 is fixedly connected to a guardrail plate 430. The guardrail plate 430 is a corrugated structure, and adjacent guardrail plates 430 are detachably connected by bolts.

[0039] In one embodiment, the main body block 230 is an inclined structure, and the right side of the main body block 230 is connected to the buffer pad 232 .

[0040] Specific usage: bury the column 100 in the soil for fixation, screw in the bolts to fix the fixing plate 110 to the ground, insert the connecting block 420 into the column 100, connect the fixing ring 421 at the left end of the connecting block 420 with the pull rope 450, and connect the telescopic rod 410 and the guardrail plate 430 connected to the telescopic rod 410 to the right end of the connecting block 420 by bolts. Adjacent guardrail plates 430 are connected by bolts, and the main block 230 is connected to the top of the column 100 by bolts, and the two sliding blocks are rotated to connect the two sliding blocks as a whole, and the slider assembly 221 connected as a whole is placed in the channel 231, and the slider assembly 221 is pushed until the warning light 210 on the top is no longer on. After the slider assemblies 221 in the same group are all located inside the main block 230, The limiting blocks 224 can be installed on both sides of the slider channel 231 by bolts; when a collision occurs, the corrugated guardrail plate 430 will play a role in buffering and energy absorption, the telescopic rod 410 can be telescoped to absorb energy, the spring on the outside of the telescopic rod 410 can buffer, the connecting block 420 can slide to the left to absorb energy, the connecting block 420 moves away from the road, and drives the buffer block 440 to move away from the road. The buffer block 440 is connected to the inside of the column 100 through the spring, and the spring inside the column 100 can perform secondary buffering; after the pulling rope 222 is stretched by the collision, multiple sliding blocks in the same group will all slide in the channel 231, so that the sliding block squeezes the press switch 223, thereby turning on the warning light 210 in the same group, which can warn the rear vehicle of an accident in which the guardrail is collided in front.

[0041] The present invention sets multiple columns 100 as a group, and the number of columns 100 in a group and the spacing between the columns 100 are designed according to actual needs. Multiple groups of columns 100 are placed on both sides of the road for protection and warning. The guardrail plate 430 is connected to the telescopic rod 410, and the telescopic rod 410 is detachably connected to the connecting block 420 by bolts. The connecting block 420 is connected to the buffer block 440 through the cooperation of the fixing ring 421 and the pull rope 450. The warning component 200 is detachably connected to the column 100 by bolts, and the sliding block inside the warning component 200 is detachably connected by threads. The limiting block 224 is detachably connected to both sides of the slider channel 231 by bolts. Therefore, during transportation and installation, the device can be divided into the column 100, the connecting block 420, the guardrail plate 430, the pulling rope 222, and the main block 230, and each part can be disassembled for easy transportation and installation.

[0042] The present invention also has good buffering capacity and energy absorption effect. When a collision occurs, the spring on the outside of the telescopic rod 410 can play a buffering role. The telescopic rod 410 can be extended and retracted in a direction perpendicular to the road. The connecting block 420 can slide and effectively absorb energy. When the connecting block 420 moves under impact, it will drive the internal buffer block 440 to move. The buffer block 440 is connected to the interior through a spring. Therefore, the spring inside the column 100 can play a secondary buffering role.

[0043] The present invention can play a warning role. When a collision occurs and causes the pulling rope 222 to be deformed and stretched, the pulling rope 222 will pull the sliding block to slide, and the sliding block will press the push switch 223, thereby turning on the warning light 210. When the pulling rope 222 is stretched, it will also drive the sliding blocks in the same group to slide, so that all the warning lights 210 in the same group are turned on. Therefore, it can effectively warn the rear vehicle of an accident ahead, thereby reducing the probability of a secondary collision.

[0044] The insert fixing block 300 of the present invention is an I-shaped structure, and four fixing plates 110 are connected to the bottom side of the column 100. The fixing plates 110 are fixed to the ground by bolts. Such a setting can enhance the stability of the column 100 and enhance its ability to grip the ground firmly. The guardrail plate 430 of the present invention is a corrugated structure, which can further enhance its buffering and impact resistance. The warning component 200 is detachably connected to the top of the column 100 by bolts, and the connecting block 420 is detachably connected to the telescopic rod 410 by bolts. The detachable connection by bolts can enhance the stability after connection.
