Protective fence facilitating adjustment of distance between stand columns
The invention relates to the technical field of safety protection, in particular to a protective fence convenient for adjusting the distance between stand columns, which comprises a vertical plate and a telescopic sleeve, a rocker and a driving gear are arranged in the vertical plate, a double-thread screw is arranged in the telescopic sleeve, a driven gear is arranged on the double-thread screw, and internal thread arc handrails are arranged at two ends of the double-thread screw. A vertical column is arranged below the double-thread screw, a transverse groove is formed in the bottom end of the vertical plate, a jacking mechanism and a double-groove sliding block are arranged at the bottom end of the vertical plate, and a buffering mechanism is arranged on one side of the telescopic sleeve. According to the French window protection device, the driving gear is driven to rotate through rotation of the hand-cranking rocker, the driving gear drives the double-thread screw to rotate through the chain, the double-thread screw drives the internal thread arc-shaped handrail to slide on the two sides of the telescopic sleeve, the distance between the stand columns is conveniently adjusted, and then the French window protection device is matched with various French windows for protection; according to the protective fence, impact force generated by contact of an external object and the protective fence can be buffered, splicing is not needed, and therefore the risk that the protective fence is bent is reduced.
本发明涉及安全防护技术领域，具体为一种便于立柱间距调节的防护栏，包括立板以及伸缩套筒，立板的内部有摇杆、主动齿轮，伸缩套筒的内部有双螺纹螺杆，双螺纹螺杆上有从动齿轮，双螺纹螺杆的两端有内螺纹弧形扶手，双螺纹螺杆的下方有立柱，立板的底端有横槽，立板的底端有顶升机构和双槽滑块，伸缩套筒的一侧有缓冲机构。本发明通过手摇动摇杆转动传动主动齿轮转动，主动齿轮通过链条传动双螺纹螺杆转动，双螺纹螺杆传动内螺纹弧形扶手在伸缩套筒的两侧滑动，方便调整立柱的间距，进而适配多种落地窗进行防护，伸缩套筒与缓冲机构相配合，能够对外物与防护栏接触产生的冲击力进行缓冲，并且无需拼接，因此降低了防护栏弯折的风险。
