Warning device for communication construction sites

Abstract

The invention discloses a warning device for communication construction sites. The warning device includes a base plate; the upper surface of the base plate is fixedly connected to two first fixing rods; the opposite surfaces of the two first fixing rods are fixedly connected to the left and right side surfaces of a driving device; the driving device meshes with a second gear; the inner surface ofthe second gear is in clamp connection with a rotating shaft; the outer surface of the rotating shaft is sleeved by a bearing; the bearing is clamped on the upper surface of the base plate; the top end of the rotating shaft is fixedly connected to the bottom end of a threaded column; the outer surface of the threaded column is in threaded connection with a threaded cap; and the left and right side surfaces of the threaded cap are respectively and fixedly connected to the opposite surfaces of two second fixing rods. Through the mutual cooperation of a motor, a first gear, the second gear, therotating shaft, the threaded column, the threaded cap, the second fixing rods, a fixing plate and a warning sign, the warning sign can be more obvious, so that the warning effects of the warning signcan be better.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a warning device for a communication construction site. Background technique [0002] Communication refers to the exchange and transmission of information between people or between people and nature through a certain behavior or medium. In a broad sense, it refers to the use of any method or medium by two or more parties who need information without violating their respective wishes. Accurate and secure transmission of information from one party to another. [0003] In order to avoid unnecessary accidents at the communication construction site, the staff often place warning signs on the construction site before construction to warn pedestrians to pay attention to safety, but most of the warning devices do not have the function of lifting and lowering, which is not obvious enough, which makes the warning signs The warning effect is not obvious. Contents of the invention ...
