Safety road guardrail capable of preventing head from being stuck

Abstract

A safety road guardrail capable of preventing the head from being stuck comprises two stand columns and a sleeve part, an upper transverse rod and a lower transverse rod are connected between the two stand columns, a vertical rod is connected between the upper transverse rod and the lower transverse rod, an anti-climbing rod is arranged above the upper transverse rod, the vertical rod penetrates through the upper transverse rod and is rotationally connected with the anti-climbing rod through a first pin shaft, the sleeve part is arranged at the joint of the vertical rod and the anti-climbing rod in a sleeving mode, the sleeve part comprises an upper sleeve, a lower sleeve, a reset spring and two connecting rods for connecting the upper sleeve and the lower sleeve, the two connecting rods are symmetrically arranged at the two axial ends of the first pin shaft, the upper ends of the two connecting rods are fixedly connected with the upper sleeve, the lower ends of the two connecting rods are rotationally connected with the lower sleeve through a second pin shaft, the reset spring has the movement trend that the upper sleeve is arranged at the joint of the vertical rod and the anti-climbing rod in a sleeving mode, the sleeve part can move in the axial direction of the vertical rod and the anti-climbing rod, and when the sleeve part moves till the second pin shaft is coaxial with the first pin shaft, the anti-climbing rod, the upper sleeve and the two connecting rods can rotate around the joint of the vertical rod and the anti-climbing rod.

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
