Size-adjustable folding type protective fence for road construction
The invention relates to a protective fence, in particular to a size-adjustable folding type protective fence for road construction. The guardrail comprises a guardrail body and the ground, the guardrail body comprises a fixed column and handrails, connecting blocks are slidably arranged at the top end and the bottom end of the two opposite sides of the fixed column, the multiple handrails are arranged, and connecting pieces for rotationally connecting the multiple adjacent handrails are arranged between the multiple adjacent handrails; according to the folding type protective fence with the adjustable size for road construction, when the connecting blocks slide out of the side walls of the fixing columns, the connecting blocks drive the baffles to be stressed to move upwards to open the exhaust holes, gas in the gas storage chamber is conveyed into the gas conveying channels so that the expansion pieces can be inflated, the expansion pieces can be inflated and expanded, and therefore the expansion pieces can be inflated and expanded; and therefore, people are protected during collision.
本发明涉及一种防护栏，具体地说，涉及一种尺寸可调节折叠型道路施工用防护栏。其包括护栏本体和地面，所述护栏本体包括固定柱和栏杆，所述固定柱相对两侧的顶底两端均滑动设置有连接块，所述栏杆设置有多个，多个相邻的所述栏杆之间设置有将二者转动连接的连接件，且位于两侧的所述栏杆端部与连接块转动连接，该尺寸可调节折叠型道路施工用防护栏中，当连接块滑出固定柱侧壁时，连接块带动挡板受力上移将排气孔打开，使储气室内的气体传输至输气道内，以对膨胀件进行充气，使膨胀件充气膨胀，从而在碰撞时对人们进行防护。
