The invention discloses a warning board for municipal construction. The warning board is characterized by comprising a movable rod, wherein a fixed plate is connected to the upper side of the movable rod, a first spring is arranged in the fixed plate, a straight rack is connected to the end of the first spring, a connecting frame is connected to the upper side of the fixed plate, and a second motor is arranged in the connecting frame; an output end of the second motor is connected with a half gear, the half gear is connected with a spur rack in a meshed mode, the upper side of the spur rack is connected with a supporting rod, the upper end of the supporting rod is connected with a fixing frame, the second motor is started, the output end of the second motor drives the half gear to rotate, and the half gear drives the spur rack to move rightwards, when the half gear does not contact the straight rack, the first spring drives the spur rack to move leftwards, under the action of the first spring and the half gear, the spur rack reciprocates leftwards and rightwards in the fixing plate, the spur rack drives the fixing frame to move leftwards and rightwards through the supporting rod, the fixing frame drives the display screen to reciprocate, and the attention of people to the warning sign is improved.
本发明公开了一种市政施工用警示牌，其技术要点是：包括活动杆，通过在活动杆的上侧连接有固定板，固定板的内部设置有第一弹簧，第一弹簧的端部连接有直齿条，固定板的上侧连接有连接框，连接框的内部设置有第二电机，第二电机的输出端连接有半齿轮，半齿轮啮合连接直齿条，直齿条的上侧连接有支撑杆，支撑杆的上端连接有固定框，开启第二电机，第二电机输出端带动半齿轮转动，半齿轮带动直齿条向右运动，当半齿轮不接触到直齿条时，第一弹簧带动直齿条向左运动，在第一弹簧和半齿轮的作用下，直齿条在固定板内左右往复运动，直齿条通过支撑杆带动固定框左右运动，固定框带动显示屏往复运动，提高了人们对警示牌的注意力。
