An anti-jamming safety road guardrail

Abstract

An anti-jamming safety road guardrail, comprising two uprights and a kit, an upper cross bar and a lower cross bar are connected between the two uprights, a vertical bar is connected between the upper cross bar and the lower cross bar, and a There is an anti-climbing bar, the vertical bar runs through the upper cross bar and is rotationally connected with the anti-climbing bar through the first pin shaft, and the kit is set at the joint between the vertical bar and the anti-climbing bar. And two connecting rods connecting the upper sleeve and the lower sleeve, the two connecting rods are arranged symmetrically at both axial ends of the first pin shaft, the upper ends of the two connecting rods are fixedly connected with the upper sleeve, and the ends of the two connecting rods The lower end is rotatably connected to the lower sleeve through the second pin shaft, and the return spring has a movement tendency to make the upper sleeve sleeve on the connection between the vertical bar and the anti-climbing bar, and the sleeve can move axially along the vertical bar and the anti-climbing bar, and When moving until the second pin shaft is coaxial with the first pin shaft, the anti-climbing pole together with the upper sleeve and the two connecting rods can rotate around the joint between the vertical bar and the anti-climbing pole.

Description

technical field [0001] The invention belongs to the technical field of municipal equipment, and in particular relates to an anti-jamming safety road guardrail. Background technique [0002] Existing road guardrails generally have several anti-climbing poles arranged at intervals on the top to avoid climbing, but often tired pedestrians will lean on the guardrail to rest, and accidentally get their heads and necks stuck between the anti-climbing poles. If force is applied, it will get stuck tighter and tighter, leading to suffocation, so it is necessary to improve. [0003] The invention patent with the application number "201611181046.3" discloses an anti-jamming safety road guardrail, which includes two vertically spaced uprights, and an upper crossbar and a lower crossbar that are parallel to each other and arranged transversely are connected between the two uprights , the upper cross bar is located above the lower cross bar, a number of vertical bars parallel to each oth...

AI Technical Summary

Problems solved by technology

But under normal circumstances, the anti-climbing pole will also rotate around the pin shaft under the action of external force. For example, when the horizontal wind is strong, the anti-climbing pole will swing left and right, and the anti-climbing pole and the vertical pole cannot be located on the same straight line. make the anti-climb pole unstable
