[0004] Although the above technical solution can store and use the entire device and also serve as a safety warning, in actual use, it can only serve as a warning by adjusting the inclination angle of the signboard, and the height of the device is fixed, which is easy to exist in the driver's blind spot and cannot serve as a safety warning. Utility Model Content

[0005] The purpose of the utility model is to provide a highway maintenance construction safety warning device, which can not only be adjusted in height to avoid appearing in the driver's blind spot and not playing a safety warning role, but also can store various working parts.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A highway maintenance construction safety warning device comprises a box body with an upper end opening, a partition plate arranged on one side of the bottom of the inner wall of the box body and dividing the box body into a device cavity and a placement cavity, and a battery installed at the bottom of the inner wall of the device cavity, the open end of the device cavity is provided with a blocking cover matched therewith, the upper end of the blocking cover is provided with a control panel, a U-shaped fixing buckle is provided on one side of the bottom of the inner wall of the placement cavity close to the partition plate, an electric push rod which can be rotated up and down and can be extended out of the open end of the placement cavity is rotatably connected between the left and right sides of the inner wall of the fixing buckle, a positioning seat is provided at the upper end of the electric push rod, limit rods are provided at the front and rear ends of the inner wall of the placement cavity near its open end, the upper ends of the two limit rods are matched with a cover plate which matches the placement cavity and is detachably connected thereto, and handles are provided at the front and rear ends of the outer wall of the cover plate.
