Technical Field

[0001] This utility model relates to the field of road warning technology, and in particular to a portable road warning device. Background Technology

[0002] When vehicles are traveling on municipal roads, they may break down and stop on the side of the road or in the middle of the road due to various unexpected situations. If they cannot be moved in time, they are at risk of being rear-ended by other vehicles. Therefore, it is necessary to set up road warning devices at a certain distance from the vehicles to remind vehicles behind to slow down in time.

[0003] A portable road warning device for traffic construction is disclosed in Chinese patent CN202021352962.0. This portable road warning device for traffic construction achieves fixation and support of the device base by installing the device shell and the first movable column, thereby better fixing the device base and reducing the displacement of the device base during use. However, this portable road warning device for traffic construction is large in size and cannot be folded, taking up a lot of space and is inconvenient to store and carry in a private car. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable road warning device that effectively solves the deficiencies of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a portable road warning device, including a base plate, a rotating shaft rotatably connected to the rear side of the base plate, a warning sign rotatably connected to the base plate via the rotating shaft, a first slot being provided in the middle of the front side of the base plate, a rocker arm rotatably connected inside the first slot, and several magnetic plates being fixedly connected to the top of the base plate.

[0006] Optionally, the base plate and the warning sign are both triangular and their shapes are compatible. A torsion spring is sleeved in the middle of the rotating shaft, and the torsion of the torsion spring makes the warning sign and the base plate perpendicular to each other.

[0007] The above technical solution involves installing a torsion spring in the middle of the rotating shaft, which keeps the warning sign in a vertical support state under the action of torsion, eliminating the need for manual support during the installation of the warning device, which consumes time and poses a safety hazard.

[0008] Optionally, the back of the warning sign is made of iron, and the magnetic force of the magnetic plate on the warning sign is greater than the torque of the torsion spring.

[0009] The above technical solution involves installing a magnetic plate on the top of the base plate. When the warning sign is rotated and comes into contact with the base plate, the magnetic plate generates a magnetic force on the iron warning sign, keeping it in contact with the base plate for easy storage and carrying.

[0010] Optionally, the middle part of the rocker is rotatably connected to the middle part of the first slot, both ends of the rocker are flush with the top of the base plate, and the end of the warning sign is provided with a second slot, the shape of which is adapted to the shape of the front side of the rocker.

[0011] The above technical solution is adopted: by setting a first slot and a rocker plate on the front side of the base plate, when a warning device is required, it is placed in the corresponding position, and stepping on the rocker plate will rotate the other end upward to lift the warning sign. After the warning sign is separated from the magnetic force of the magnetic plate, it will automatically rotate to a vertical position under the action of the torsion spring, thus achieving the warning effect. The operation is simple and quick. The second slot is set so that the front half of the rocker plate is exposed and can be stepped on directly.

[0012] Optionally, a reflective strip is fixedly connected to the surface of the warning sign, and a handle is fixedly connected to the rear center of the base plate.
