If the direction needs to be adjusted, pull the spray painting template 32 to turn over, and clamp the clamping block 33 to the clamping groove 31 on the other side.

[0029] Four self-locking universal wheels 13 are provided at the lower end of the vehicle body 1; wherein, the four self-locking universal wheels 13 are respectively located at the four corners of the vehicle body 1; a handrail 14 is fixedly installed at the side end of the vehicle body 1; wherein, the handrail 14 is located on the side away from the storage barrel 11, and the handrail 14 is pushed, and the handrail 14 drives the vehicle body 1, and the vehicle body 1 drives the self-locking universal wheels 13 to roll, and the vehicle body 1 is pushed to the road spray painting point.

[0030] A support frame 2 is rotatably mounted on the upper end of the vehicle body 1, and a slide groove 21 is provided at the lower end of the support frame 2; wherein, the support frame 2 is located on one side of the pump body 12; a slider 22 is slidably mounted on the inner wall of the slide groove 21, and a spray painting unit 23 is arranged below the slider 22; wherein, the spray painting unit 23 is rotatably mounted with the slider 22; a support ring 24 is provided at the side end of the support frame 2, and a material delivery hose 25 is sleeved on the inner wall of the support ring 24; wherein, one end of the material delivery hose 25 is fixedly connected to the pump body 12, and the other end of the material delivery hose 25 is fixedly connected to the spray painting unit 23, and the pump body 12 is started, and the pump body 12 pumps the spray painting raw material into the material delivery hose 25, and then the material delivery hose 25 introduces it into the spray painting unit 23, and then the spray painting unit 23 performs spray painting.

[0031] Working principle:

[0032] The first step is that when the road marking device for urban road traffic is used, the handrail 14 is pushed, the handrail 14 drives the vehicle body 1, and the vehicle body 1 drives the self-locking universal wheel 13 to roll, and the vehicle body 1 is pushed to the road spraying point, and then the spraying template 32 is adjusted according to the direction of the spraying arrow, the spraying template 32 is plugged into the vehicle body 1, and the clamping block 33 on the spraying template 32 is clamped and fixed in the clamping groove 31, and then spraying is performed.
