Description

Technical Field

[0001] The utility model belongs to the technical field of traffic accident warning devices, and in particular relates to a warning device for road traffic accidents. Background Art

[0002] Current traffic accident warning devices are generally made of red plastic and coated with reflective materials. They do not emit light themselves and are passive traffic warning devices. During the day, they use the reflection of natural light to alert oncoming vehicles from a distance, with an effective visual distance of approximately 1,000 meters. At night, they use the reflection of street lights and car lights to alert oncoming vehicles from a distance, with an effective visual distance of approximately 600 meters.

[0003] If the existing warning device is located at a location with weak light source, or if too much dust is adsorbed on the surface of the reflective material used for warning, the reflected light will be dim and difficult to be found, thus reducing the warning effect and easily causing secondary traffic accidents. In addition, the warning range of the existing warning device is narrow and the warning functionality is not comprehensive enough, thereby reducing the warning effect of the warning device.

[0004] Secondly, the existing warning equipment has poor adjustability and cannot be used for road warnings in different locations, which greatly reduces the warning range and applicability of the device and urgently needs to be developed. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model provides a warning device for road traffic accidents. The warning wire roll can be unfolded by pulling the magnet positioning strip outward, and then the magnet positioning strip is placed in the positioning slot of the adjacent warning device and fixed with the magnet seat by magnetic attraction to form a continuous and complete warning area. The elasticity of the coil spring can help the warning wire roll to automatically rewind and reset and be stored in the storage slot, reducing the space occupied when not in use. Therefore, the warning device can be self-regulated according to the actual area range that needs to be warned. The unfolded warning wire roll can form a long warning area, increase the warning range and effect, and improve the functionality and applicability of the device.

[0020] 2. The utility model provides a warning device for road traffic accidents. By rotating the first transmission shaft, the first screw can be driven to rotate, so that the lifting cylinder screwed to the outside of the first screw can move up and down, and then the warning head column can be driven to move up and down. That is, the height of the warning head column can be adjusted by rotating the first transmission shaft, thereby increasing the height range of the warning and improving the adjustability of the equipment.

[0021] 3. The utility model provides a warning device for road traffic accidents. By rotating the second transmission shaft, the second screw can be driven to rotate, so that the lifting plate screwed to the outside of the second screw can move up and down, and then the height of the roller group can be adjusted, so that the roller group can be extended or retracted into the through opening. When the roller group moves outside the through opening and contacts the ground, it can facilitate the movement of the entire device. On the contrary, when the roller group is stored in the support seat, the friction-increasing base can directly contact the ground to increase friction, thereby improving the stability of the device when placed on the road surface.

[0022] 4. The utility model provides a warning device for road traffic accidents, which can enlarge the warning reflective area by arranging reflective surfaces on the outer surfaces of the support body and the warning head column. BRIEF DESCRIPTION OF THE DRAWINGS
