Anti-crossing guard bar

Abstract

The invention discloses an anti-crossing guard bar. The anti-crossing guard bar includes a vertical column and a base connected with the lower end of the vertical column in a sleeving mode. The lowerend of the vertical column is provided with a limited bulge. The upper end of the vertical column is provided with a top cover. The vertical column is provided with at least three main positioning holes. Each main positioning hole is internally connected with a positioning column used for limiting sliding down of the vertical column in an inserted mode. The vertical column is provided with at least two circular grooves. According to the anti-crossing guard bar, through rotatable vice handrails, a cross-over person is prevented from finding force bearing points, and meanwhile, the difficulty that the cross-over person makes contact with the opposite ground is increased; furthermore, the multiple sets of vice handrails can also be arranged in a staggered mode to prevent person from drillingin through a gap. Each element forming the handrails can be disassembled freely, so that packing and conveying are convenient. The vice handrails can further be fixed directly through a limiting device; troubles of single installing are avoided; and the connecting seat can be wholly disassembled to make the vertical column to retract back to the ground, so that temporary opening requirements are met rapidly.

Description

technical field [0001] The invention relates to the technical field of guardrail design, in particular to a guardrail against overturning. Background technique [0002] Railings are a commonly used protective device. Railings can not only play a protective role, but also avoid blocking the line of sight, so they are irreplaceable. However, the existing railing structures are relatively fixed and easy to climb over, so it is difficult to provide effective protection. , and the guardrail is mainly installed by welding, which is inconvenient to write later. If we can invent a new guardrail that can be effectively placed and overturned, and is convenient to disassemble and transport, this kind of problem can be solved. For this reason, we provide an anti-overturn guardrail. Contents of the invention [0003] The object of the present invention is to provide an anti-surmounting guardrail to solve the problems raised in the above-mentioned background technology. [0004] In ord...
