Description

Technical Field

[0001] The utility model relates to the field of road safety warnings, in particular to a municipal road safety warning sign. Background Art

[0002] Warning signs are conventional emergency equipment on cars. They are generally triangular in appearance, so they are also called triangular warning signs. Warning signs must strictly comply with the requirements of the Road Traffic Safety Law and are passive reflectors made of plastic reflective materials. The principle is that when car owners encounter sudden traffic accidents on the road, they use the reflective properties of warning signs to remind other vehicles to avoid them to avoid secondary accidents. During municipal road construction, warning signs need to be placed at a certain distance from the construction site to remind passers-by and prevent danger.

[0003] The warning signs of existing warning signs are generally fixed, which is not convenient to change during use. Generally, the warning signs are directly replaced, which is not only time-consuming and labor-intensive, but also a waste of resources. Therefore, a municipal road safety warning sign is proposed to address the above problems. Utility Model Content

When the two sets of connecting rods follow the cross bar to rise, they will drive the two sets of limit rings to slide on the two sets of limit rods, which have an auxiliary support effect on the installation frame and improve the stability during work. When it is necessary to flip the warning sign body, the slidable positioning rod can be removed from the positioning hole, so that the warning sign body can be released from the positioning and then it can be flipped over to replace the warning slogan. When it is necessary to release the positioning, the positioning rod can be first pulled to move out of the positioning hole through the pull ring. While pulling, the spring will be compressed under the action of the fixing plate. After the warning sign body is flipped over, the pull ring is loosened and the positioning rod will be reset in the positioning hole under the action of the spring to fix the warning sign body.

[0023] During operation, the required slogans are first set on both sides of the two sets of warning sign bodies 10. The universal wheels 2 at the bottom of the base 1 are used to facilitate the movement of the warning sign body 10 to the construction area for use. The warning sign body 10 is supported by the support column 3, and the cross bar 5 can be lifted and lowered by the lifting mechanism 8. Due to the fixed connection between the cross bar 5 and the two sets of connecting rods 6, the two sets of connecting rods 6 will follow the lifting, and the warning light 11 can improve the warning effect of pedestrians. Therefore, the height of the mounting frame 7 can be adjusted under the action of the two sets of connecting rods 6, so that the height of the warning sign body 10 can be adjusted. When the slogan needs to be replaced, the two sets of warning sign bodies 10 can be flipped over under the action of the rotating shaft 12, and then the two sets of warning sign bodies 10 are fixed by the positioning mechanism 9, so that it is convenient to quickly change when in use, saving time and effort and improving work efficiency.

[0024] Furthermore, the lifting mechanism 8 includes a bearing seat 801 , which is fixedly mounted on the inner bottom surface of the mounting hole 4 , and a screw rod 802 is rotatably mounted in the mounting hole 4 through the bearing seat 801 , and the screw rod 802 is threadedly penetrates the cross bar 5 .

[0025] During operation, by driving the screw rod 802 to rotate, the cross bar 5 can move vertically up and down under the limit of the mounting hole 4 under the cooperation of the thread when the screw rod 802 rotates, thereby achieving the purpose of lifting the cross bar 5.

[0026] Furthermore, the upper end of the screw rod 802 rotates and penetrates to the upper end surface of the support column 3 , and a motor 803 for driving the screw rod 802 to rotate is fixedly mounted on the upper end surface of the support column 3 .
