[0002] Highway construction refers to the processing and construction of highway structures. During highway construction, due to the limitations of information dissemination, it is usually necessary to set up various guiding devices to guide vehicles or personnel to prevent irrelevant personnel from interfering with road construction. Guide signs are one of the guiding devices and are widely used because of their strong visibility.

[0003] Existing highway construction guide signs have a fixed structure and are large in size, making them inconvenient to transport and retract after use. Utility Model Content

[0004] The utility model aims to provide a highway construction guide road sign, which has the characteristic of being easy to transport and retract.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a highway construction guide sign, comprising a box body, the upper end face of the box body being movably connected to a box cover, a multi-stage electric telescopic rod being fixedly connected between the inner lower end of the box body and the lower end face of the box cover, the lower end face of the box cover being rotatably connected to two first LED display light boards distributed on the left and right, the side walls opposite to each other of the two first LED display light boards being rotatably connected to second LED display light boards through hinges, the first LED display light boards being electrically connected to the second LED display light boards, the lower end face of the box cover being provided with two slide grooves distributed on the left and right, the upper end face center of the second LED display light board being rotatably connected to a slider matching the slide groove.

[0006] In order to increase the stability of the box, as a preferred highway construction guide sign of the present invention, the outer wall of the box is provided with a plurality of evenly distributed support mechanisms, the support mechanism includes two symmetrically distributed rotating rods rotatably connected to one side wall of the box through a hinge seat, a support plate is rotatably connected between the two rotating rods, and a side wall of the box is provided with a limiting groove matching the upper end of the support plate.

[0007] In order to drive the slider to move, as a preferred highway construction guide sign of the present invention, the internal rotation of the slide is connected to a screw threadedly connected to the slider, and a motor is installed inside the box cover, and the output end of the motor is fixedly connected to the screw.

[0008] In order to facilitate the control of the multi-stage electric telescopic rod, the first LED display light board, the second LED display light board and the motor, as a preferred highway construction guide sign of the present invention, the upper end surface of the box cover is provided with a groove, and the lower end of the inner part of the groove is equipped with a control panel electrically connected to the multi-stage electric telescopic rod, the first LED display light board, the second LED display light board and the motor.

[0009] In order to provide power to the multi-stage electric telescopic pole, the first LED display light board, the second LED display light board, the control panel and the motor, as a preferred highway construction guide sign of the utility model, two batteries distributed on the left and right are installed at the lower end of the interior of the box, and the batteries are electrically connected to the multi-stage electric telescopic pole, the first LED display light board, the second LED display light board, the control panel and the motor respectively.

[0010] In order to fix the support plate, as a preferred highway construction guide sign of the present invention, a first magnet is embedded in one side wall of the box, and a second magnet matching the first magnet is embedded in one side wall of the support plate.

[0011] In order to protect the control panel, as a preferred highway construction guide sign of the present invention, the inner upper end of the groove is rotatably connected to a protective cover.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The multi-stage electric telescopic rod cooperates with the box cover to drive the first LED display light board and the second LED display light board to rise. After rising to the appropriate height, the multi-stage electric telescopic rod stops, and then the motor drives the screw rod to rotate, the screw rod drives the slider to move, and the slider drives the second LED display light board to move. Since the first LED display light board and the second LED display light board are rotatably connected by a hinge, the first LED display light board and the second LED display light board slowly rotate during the movement of the second LED display light board, so that the first LED display light board and the second LED display light board are unfolded. After the first LED display light board and the second LED display light board are unfolded, they form a complete screen, thereby completely unfolding the guide sign;

[0014] After use, reverse the above steps to fold and shrink the guide sign into a box, so that the guide sign can be easily transported and stored. BRIEF DESCRIPTION OF THE DRAWINGS
