Municipal multifunctional protective fence
The invention relates to a municipal multifunctional protective fence. According to the technical scheme, the device comprises two stand columns, a rectangular frame is arranged between the two stand columns, a plurality of blocking supporting units are evenly distributed in the rectangular frame side by side at intervals, each blocking supporting unit comprises a first vertical plate capable of moving up and down, and the left side and the right side of each first vertical plate are each provided with a second vertical plate installed in the rectangular frame in a sliding mode; when the first vertical plate moves upwards relative to the rectangular frame, the two second vertical plates are driven by connecting rods to move away from the first vertical plate in the opposite direction, a vertical first sliding groove communicated with a hollow cavity of the stand column is formed in the inner side of each stand column, a sliding block is arranged in the first sliding groove, and wedge-shaped blocks are arranged on the upper portions of the left side edge and the right side edge of the rectangular frame. The left side and the right side of the upper side edge of the rectangular frame are each provided with a gear, a supporting leg is fixed to the outer edge face of each gear, a rack capable of being meshed with the corresponding gear is fixed to the rear side of each stand column, and an inclined rod with the upper end inclining towards the front side is arranged on the outer side of each rack.
本发明涉及一种市政多功能防护栏；其解决的技术方案包括两个立柱，两个立柱之间设有一个矩形框，矩形框内并排间隔均布有多组阻挡支撑单元，每组阻挡支撑单元包括一个可上下移动的第一竖板，每个第一竖板的左右两侧分别设有一个滑动安装在矩形框内的第二竖板，第一竖板相对矩形框向上运动时经连杆驱动两个第二竖板向远离第一竖板反向移动，立柱的内侧设有一个竖向且与立柱空心腔连通的第一滑槽，第一滑槽内设有一个滑块，矩形框的左右两侧边的上部设有一个楔形块，矩形框上侧边的左右两侧各设有一个齿轮，每个齿轮的外缘面上固定有一个支腿，每个立柱的后侧固定有一个可与对应齿轮啮合的齿条，每个齿条的外侧设有一个上端向前侧倾斜的斜杆。
