Abstract

The invention is applicable to the technical field of rail transit, and provides a rail transit safety sign convenient to disassemble and maintain, which comprises a device shell with an opening in the front end face, a working cavity is formed in the device shell, lighting lamp strips are arranged on two sides in the working cavity, and a display board is arranged in the working cavity. According to the safety sign convenient to disassemble and maintain for the rail transit, when a worker disassembles the device shell, a rotating disc is rotated, then a connecting rod pulls a sliding block to move, the sliding block drives a fixing rod to be separated from the interior of the connecting block, then the device shell is pulled out upwards, and the safety sign is convenient to disassemble and maintain. The device shell can be disassembled by releasing the connection with the mounting seat, so that the problems that a worker needs to always additionally carry a tool for disassembling the safety indication board during maintenance, the load carried by the worker is increased, and the safety indication board is difficult to disassemble when the tool is lost, and the operation is troublesome are solved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a safety indicator board for rail transit which is easy to disassemble and maintain. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transit, which are not only used in long-distance land transportation, but also widely used in short- and medium-distance urban public transportation. When the current rail is overhauled or fails ahead, it is usually necessary to place safety instructions in advance warning sign. [0003] Most of the existing safety signs for rail transit use tools to disassemble and assemble through bolts during use, which causes the sta...
