Description

Technical Field

[0001] The utility model relates to the technical field of road guardrails, in particular to a nighttime guardrail for road safety. Background Art

[0002] Road guardrail is a safety facility widely used in traffic buildings such as highways, urban roads, bridges and tunnels. It is mainly composed of columns, cross bars and wire mesh, which can prevent vehicles from entering another lane or falling into a low place due to unexpected situations such as loss of control, thereby protecting the safety of road users. The existing publication number is CN220503758U, which discloses a nighttime guardrail for road safety. By inserting the top rod into the interior of the connector and engaging the stepped shaft with the interior of the positioning groove, when the guardrail body is hit to a predetermined force, the expansion pad is squeezed inward to cause the limit ring pad to shrink and reduce the external diameter. At this time, the limit ring pad slides outward through the slideway to drive the guardrail body to move outward, and then the buffer is aligned to form a buffer and the tension is used to reduce the outward impact force, which can effectively prevent the vehicle from continuously rushing outward to affect external equipment and pedestrians, and can also effectively avoid the occurrence of joint situations to reduce the degree of loss of adjacent guardrail bodies, which is convenient for subsequent maintenance and use. However, the guardrail needs to be installed using bolts and other components, which greatly reduces the efficiency of disassembly and assembly of the guardrail, and increases the difficulty of installation and disassembly of the guardrail, which brings certain adverse effects to actual use, so it needs to be improved.
