Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and in particular relates to a road direction diversion type guardrail. Background Art

[0002] Road diversion guardrail is a traffic safety facility, which is mainly used to guide and control the direction of road traffic and ensure driving safety. It is usually installed at road intersections, toll booths, service areas and other places. Through different designs and installation methods, it can achieve functions such as vehicle separation, merging, and steering, improve road traffic efficiency, and reduce the occurrence of traffic accidents.

[0003] At present, most existing road guardrails fix the column bracket part to the ground by bolts. When a vehicle collides, the bolts are often pulled out or broken, causing the column to tilt, resulting in some bolts remaining on the ground and unable to be directly removed, making subsequent maintenance difficult and not conducive to inspection and replacement;

[0004] In order to solve the above problems, this application proposes a road direction diversion type guardrail. Utility Model Content

[0005] The purpose of the utility model is to provide a road direction diversion type guardrail, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a road-direction diversion type guardrail, comprising a diversion guardrail, wherein combined columns are arranged at both ends of the diversion guardrail, a base for being connected and fixed to the ground is arranged below the column, a protruding sheath is arranged above the base, a connecting seat for connecting the column is installed inside the sheath, protruding plug plates are arranged on both sides of the lower end of the column, folding plates for being connected and fixed to the sheath are arranged on both sides of the connecting seat, the plug plates are used to be inserted into the gap between the connecting seat and the folding plates and to push the folding plates outwards to prevent them from loosening, a clamping plate for fixing the column is arranged above the connecting seat, the clamping plate is used to replace bolts to withstand external impact force, and prevent the bolts from being unable to be taken out after being broken by force, which affects maintenance work.

[0008] Furthermore, a protruding top block is provided on the outer side of the folding plate, and a guide slope is provided on one side of the bottom of the top block, and the guide slope is used to automatically form a guide to tilt the folding plate when it abuts against the edge of the sheath.

[0009] Furthermore, a positioning groove for installing a card board is provided at the bottom of the column.

[0010] Furthermore, limiting grooves for snap-fitting and connecting the top block are provided inside the two sides of the sheath.

[0011] Furthermore, side grooves for installing folding plates are provided on both sides of the sheath.

[0012] Furthermore, an elastic arc plate is installed inside the side groove to drive the folding plate to automatically pop outward.

[0013] Furthermore, the adapter is also used to protect the base to prevent the performance of the internal bolts from being affected by external impact.

[0014] The utility model has the following beneficial effects:

[0015] The utility model is directly provided with a combined structure of the column, the base and the adapter. In subsequent use, when a vehicle collides, the column is driven to tilt to one side and the clamping plate is bent until it breaks. Compared with the existing installation method, it can effectively avoid the situation where the broken bolts remain on the ground and cannot be taken out, which is convenient for repairing and replacing the column to ensure the subsequent use performance;

[0016] The utility model can directly insert the inside of the sheath after folding plates are arranged on both sides of the adapter. At this time, the top block automatically engages with the inside of the limiting slot to form a limit. Subsequently, when the column is assembled, the plug plate is driven to be inserted between the adapter and the folding plate to form reinforcement. After this arrangement, the connection and fixation can be conveniently formed, avoiding the combined structure from affecting the laying efficiency. At the same time, the assembly and disassembly are simple and are conducive to batch laying operations.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
