Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail with an anti-collision function. Background Art

[0002] Guardrails are facilities used to enclose or isolate areas, usually on roads, bridges, stairs, construction sites or other places that require safety protection. Guardrails are usually designed with materials such as metal, plastic, wood or concrete to ensure that they have sufficient strength and stability. The function of guardrails is to prevent people or vehicles from accidentally falling or crossing the boundary, and to provide a certain degree of isolation protection to ensure the safety of the surrounding environment. On the road, guardrails can also be used to guide traffic and reduce the occurrence of traffic accidents.

[0003] The existing guardrail inserted into the soil will cause the guardrail to tilt when it is hit by external force, and the part of the guardrail inserted into the soil will loosen. After the soil is loosened for a long time, the guardrail will collapse and lose its protective function. Moreover, when the guardrail is hit, each different angle of impact will cause the guardrail to tilt in different directions. Some angles of the guardrail will cause the guardrail to collapse, while others will not. It is impossible to ensure that the guardrail will not collapse when it is hit. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a guardrail with anti-collision function, including a fixed column 1 and a railing 3, a reinforcement part 2 is arranged inside the fixed column 1, and the reinforcement part 2 includes: a positioning column 21, a telescopic column 22, a tension spring 23, a clamping plate 24, a mounting leg 25, a pull block 26, a hinged rod 27, a reinforcement anchor 28, a rotating plate 29, a resistance groove 210, a fixed plate 211, a slide groove 212, a slider 213, a lever 214, a shaft 215, a push rod 216, a linkage ring 217, a baffle 218, a guide rod 219, a reset spring 220, a slide rod 221, and a limit block 222.

[0026] The top surface of the positioning column 21 is fixedly connected to the inner wall of the fixed column 1, and the inner side of the positioning column 21 is penetrated and slidably connected with a telescopic column 22, and the telescopic column 22 is penetrated and fixedly connected with a card plate 24, and the bottom end of the telescopic column 22 is penetrated and slidably connected with a mounting leg 25, and the top surface of the pull block 26 is penetrated and fixedly connected by the telescopic column 22, and the surface of the pull block 26 is hinged with a hinge rod 27, and the end of the hinge rod 27 away from the pull block 26 is hinged with a reinforcement anchor 28, and the telescopic column 22 moves upward while pulling the pull block 26, and the pull block 26 drives the reinforcement anchor 28 to move upward through the hinge rod 27, and the reinforcement anchor 28 will extend out of the mounting leg 25 when it contacts the inner edge of the mounting leg 25, and the rotating plate 29 is rotatably connected to the inner wall of the fixed column 1, and the surface of the rotating plate 29 is provided with a contact groove 2 10. A fixing plate 211 is fixedly connected to the inner wall of the fixing column 1. A sliding groove 212 is provided on the surface of the fixing plate 211. A slider 213 is slidably connected to the inner side of the sliding groove 212. A limiting block 222 is fixedly connected to the bottom surface of the slider 213. When the slider 213 slides along the sliding groove 212, it will contact the return spring 220 to compress the return spring 220. When the slider 213 slides along the sliding groove 212, it will also bring the sliding rod 221 to slide along the contact groove 210. The sliding rod 221 will contact the contact groove 210 to force the rotating plate 29 to rotate, thereby making the six groups of sliding rods 221 drive the slider 213 to slide along the sliding groove 212 and drive the limiting block 222 to expand. The top surface of the slider 213 is fixedly connected to the sliding rod 221. The sliding rod 221 penetrates the contact groove 210 and is slidably connected. The slider 213 is hinged with a lever 214 on the side, and a push rod 216 is hinged at one end of the lever 214 away from the slider 213. When the push rod 216 is subjected to a thrust, the lever 214 is driven to rotate with the center of the shaft 215 as the axis, so that the end of the lever 214 close to the slider 213 drives the slider 213 to slide along the slide groove 212. The surface of the lever 214 is penetrated and rotatably connected with the shaft 215, and the shaft 215 is fixedly connected to the surface of the fixed plate 211. The push rod 216 penetrates the fixed column 1 and is slidably connected. The end of the push rod 216 away from the lever 214 is fixedly connected with a linkage ring 217. When installing, the installation leg 25 is inserted into the soil. When the guardrail is hit by an external force, it will first hit the outermost baffle 218. When the baffle 218 is hit, it will push the push rod 216 through the linkage ring 217, and the baffle 218 is fixedly connected to the surface of the linkage ring 217. A guide rod 219 is fixedly connected to the inner side of the slide groove 212, and the guide rod 219 passes through the slider 213 and is slidably connected. Through the six groups of push rods 216, the linkage ring 217 can cooperate with the rotating plate 29 to make the six groups of limit blocks 222 expand outward after being hit at any angle, instead of only being reinforced when the baffle 218 is hit.The top of the telescopic column 22 is fixedly connected with a tension spring 23, and the top of the tension spring 23 is fixedly connected to the inner side of the positioning column 21. The six groups of slide rods 221 drive the slider 213 to slide along the slide groove 212 and drive the limit block 222 to expand, so that the limit block 222 will no longer block the card plate 24. After the card plate 24 is no longer blocked by the limit block 222, the tension spring 23 will pull the telescopic column 22 upward. The side of the slider 213 penetrated by the guide rod 219 is fixedly connected with a return spring 220, and the end of the return spring 220 away from the slider 213 is fixedly connected to the inner side of the slide groove 212.

[0027] Based on the above embodiment, during installation, the installation leg 25 is inserted into the soil. When the guardrail is hit by external force, it will first hit the outermost baffle 218. When the baffle 218 is hit, it will push the push rod 216 through the linkage ring 217. When the push rod 216 is pushed, it will drive the lever 214 to rotate with the center of the shaft 215 as the axis, so that the end of the lever 214 close to the slider 213 drives the slider 213 to slide along the slide groove 212. When the slider 213 slides along the slide groove 212, it will resist the return spring 220 to compress the return spring 220. When the slider 213 slides along the slide groove 212, it will also drive the slide rod 221 to slide along the resistance groove 210. The slide rod 221 will resist the resistance groove 210 and force The rotating plate 29 is rotated, and then the six groups of sliding rods 221 drive the sliding blocks 213 to slide along the sliding grooves 212 and drive the limit blocks 222 to expand, so that the limit blocks 222 will no longer block the card plate 24. After the card plate 24 is no longer blocked by the limit blocks 222, the tension spring 23 will pull the telescopic column 22 upward, and the telescopic column 22 will pull the pulling block 26 to move upward while moving upward. The pulling block 26 will drive the reinforcing anchor 28 to move upward through the hinge rod 27, and the reinforcing anchor 28 will extend out of the mounting leg 25 when it hits the inner edge of the mounting leg 25, and the contact area between the entire mounting leg 25 and the soil is expanded through the reinforcing anchor 28, so that the reinforcing anchor 28 and the soil are relatively more firmly connected, preventing the guardrail from directly collapsing when it is hit.

[0028] Through the six groups of push rods 216, when the linkage ring 217 is hit at any angle, the six groups of limit blocks 222 can be expanded outward in cooperation with the rotating plate 29, instead of being reinforced only when the baffle plate 218 is hit. It can better adapt to multi-angle collisions in actual environments and be reinforced, and has stronger adaptability.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
