[0004] This patent has the effect of improving the installation efficiency of highway guardrails, but the existing guardrails do not have anti-collision functions. When a car hits a rigid guardrail, the guardrail cannot effectively absorb and disperse the impact force. The force generated by the collision will be directly transmitted to the guardrail and the car itself, causing significant damage to both the guardrail and the car. Therefore, we have proposed a new type of highway anti-collision guardrail. Utility Model Content

[0005] The utility model aims to solve the existing problem that when a car hits a rigid guardrail, since the guardrail cannot effectively absorb and disperse the impact force, the force generated by the collision will be directly transmitted to the guardrail and the car itself, causing significant damage to both the guardrail and the car.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a highway anti-collision guardrail, including a guardrail body, a surface of the guardrail body is provided with an anti-collision component, the anti-collision component includes a connecting rod, two groups of the connecting rods are respectively connected to the two side surfaces of the guardrail body, the outer surface of the connecting rod is sleeved with a first spring, one end of the connecting rod is connected to a push block, one side of the push block is connected to a second spring, the outer surface of the second spring is provided with a sleeve, the upper and lower ends of one side of the sleeve are provided with a first rotating shaft, the surface of the first rotating shaft is connected to a connecting tube, a third spring is provided inside the connecting tube, one side of the third spring is connected to a push rod, one end of the push rod is connected to the second rotating shaft, one side of the two groups of the sleeves is fixedly connected with an anti-collision plate, a guide block is provided on the side of the anti-collision plate close to the guardrail body, and a guide groove is opened at the inner center position of the guardrail body.

[0007] Furthermore, the outer surface of the push block is in contact with the inner surface wall of the sleeve, and a sliding connection is formed between the push block and the sleeve.

[0008] Furthermore, the push block forms an elastic structure through the sleeve and the second spring, and the sleeve and the first spring form an elastic structure.

[0009] Furthermore, the sleeve is rotationally connected to the connecting cylinder via the first rotating shaft, and an elastic structure is formed between the push rod and the third spring.

[0010] Furthermore, the position and size of the guide block match the position and size of the guide groove.

[0011] Furthermore, a disassembly assembly is provided on the front surface of the anti-collision plate, and the disassembly assembly includes a threaded hole, and the threaded hole is transversely opened on the surface of the anti-collision plate.

[0012] Furthermore, a protective plate is attached to the outer surface of one side of the anti-collision plate close to the threaded hole, and buffer sponges are provided on the outer surfaces of the upper and lower ends of the protective plate. Slots are transversely opened inside the protective plate, and bolts are inserted into the inside of each group of slots.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the guardrail body is hit by a car, the anti-collision plate will push the sleeve to be squeezed toward the first spring. At the same time, the second spring and the third spring will also be squeezed, which effectively reduces the impact force between the guardrail body and the car, thereby achieving an anti-collision effect and avoiding the problem of serious damage caused by the rigid collision between the guardrail and the car.

A guide block 212 is arranged on the side of the anti-collision plate 211 close to the guardrail body 1. A guide groove 213 is opened at the inner center position of the guardrail body 1. The outer surface of the push block 203 is in contact with the inner surface wall of the sleeve 204. A sliding connection is formed between the push block 203 and the sleeve 204. An elastic structure is formed between the push block 203 and the second spring 205 through the sleeve 204. An elastic structure is formed between the sleeve 204 and the first spring 202. The sleeve 204 is rotatably connected to the connecting tube 207 through the first rotating shaft 206. An elastic structure is formed between the push rod 209 and the third spring 208. The position and size of the guide block 212 match the position and size of the guide groove 213.

[0025] The effect achieved by the entire embodiment 1 is that when the guardrail body 1 is hit by a car, the anti-collision plate 211 will push in the direction of the guardrail body 1 and drive the sleeve 204 to squeeze the first spring 202. At this time, the connecting rod 201 will also push the push block 203 to squeeze the second spring 205, thereby achieving a two-way buffering effect. At the same time, the sleeve 204 will also rotate through the first rotating shaft 206 and the connecting tube 207, and make the top rod 209 push in the direction of the third spring 208 to squeeze the third spring 208.

[0027] The effect achieved by the entire embodiment 2 is that when the guardrail body 1 is hit by a vehicle, the protective plate 302 is the first stress point and can act as a protective component through the buffer sponge 303. When the collision force is not large and the protective plate 302 is damaged alone, all the bolts 305 can be removed, and the protective plate 302 can be replaced separately. The bolts 305 can be passed through the slots 304 and then threadedly installed and fixed to the threaded holes 301, thereby reducing the maintenance cost of the guardrail body 1 after the collision.

[0028] Working principle: When the guardrail body 1 is hit by a car, the anti-collision plate 211 will push the sleeve 204 to be squeezed toward the first spring 202. At the same time, the second spring 205 and the third spring 208 will also be squeezed, effectively reducing the impact force between the guardrail body 1 and the car, thereby achieving an anti-collision effect and avoiding the problem of serious damage caused by the rigid collision between the guardrail and the car. When the guardrail body 1 is hit by a car, the protective plate 302 is the first collision point. If the damage to the guardrail body 1 is not serious, only the protective plate 302 can be replaced, reducing the maintenance cost of the guardrail body 1.
