Description

Technical Field

[0001] The invention discloses a portable warning sign for highways, which is used to warn when a vehicle breaks down on a highway during road traffic, and belongs to the field of road traffic, and particularly relates to a warning sign that can intuitively control the placement distance, can be folded, and is easy to carry. Background Art

[0002] According to the Road Traffic Safety Law of the People's Republic of China, when a motor vehicle breaks down on a highway, a warning sign should be placed 150 meters away from the direction of the broken vehicle during the day or 250 meters away from the vehicle body at night to warn other vehicles to avoid collisions between other vehicles and the broken vehicle causing casualties. Existing safety warning signs cannot determine the control distance when they are placed. When the driver does not place the safety warning sign at the prescribed safety distance, the braking distance for the driver of the vehicle behind is too short when seeing the safety warning sign, which can easily cause a secondary accident. In addition, the safety warning device is mostly in the shape of a triangular warning sign with a flat structure. When the warning sign is deflected by external factors, it will affect the reflective effect of the warning sign.

[0003] Announcement No. CN210712618U discloses a warning sign for use on highway bridges, including a rectangular shell, a panel, a roller, a connecting plate, a telescopic rod, a docking plate, a warning shell, a warning plate, a push rod, a fastening knob, a pull ring and a buckle groove. The device is inconvenient to control the moving distance when moving, which may cause a secondary accident due to the short placement distance. In addition, the warning sign is flat, and when the angle is deflected, it affects the observation effect of other vehicles behind the warning sign.

[0004] Announcement No. CN210177397U discloses a highway warning sign with good stability, including a warning sign body, a bottom stabilizing seat and an upper stabilizing foot. The bottom end of the warning sign body is connected to the upper end of the bottom stabilizing seat. The warning sign body is an equilateral triangle. The left and right sides of the horizontal plate are respectively provided with a first inclined plate and a second inclined plate, and the first inclined plate and the second inclined plate are rotatably connected to the horizontal plate through a rotating shaft. A storage groove is provided on the upper end of the horizontal plate, and a rotating column is fixedly installed on the middle part of the lower end of the horizontal plate. The left and right sides and the bottom of the rotating column are respectively provided with a first stabilizing foot and a second stabilizing foot. The upper stabilizing foot consists of a third stabilizing foot, a horizontal rotating shaft, a longitudinal rotating shaft and an anti-slip sleeve, and is installed in the middle and upper part of the first inclined plate and the second inclined plate. The device is inconvenient for the driver to control the placement distance when placing it. If the safety warning sign is not placed at the specified safety distance during placement, it will easily cause a secondary accident. Summary of the invention

[0017] When in use, in the initial state, the airbag (2) is contracted, the auxiliary hinge plate (11) covers the main hinge plate (10), and the airbag (2) is located between the main hinge plate (10) and the auxiliary hinge plate (11). The foldable structure occupies a small area and is easy to carry. When a motor vehicle breaks down on a highway and a warning sign is needed, the warning sign is taken out and the auxiliary hinge plate (11) is rotated so that the auxiliary hinge plate (11) rotates 180 degrees. The main hinge plate (10) and the auxiliary hinge plate (11) form a triangular plate corresponding to each other. The suction cup (5) is adsorbed on the faulty vehicle, and the warning sign is held and moved to the rear of the faulty vehicle. The coil roller (9) rotates around the support frame (8) and the warning is judged by the scale on the traction rope (6). The distance the sign moves is controlled to control the distance at which the warning sign is placed, the air pump (4) is turned on, and the air pump (4) inflates the airbag (2), the airbag (2) being a triangular pyramid structure, so that the warning sign is a triangular pyramid structure, and when the angle of the warning sign is deflected, the reflectivity of the warning sign is less affected. After use, the suction cup (5) is removed, the traction rope (6) is pulled back, and the traction rope (6) pulls the coil roller (9) to move in the direction of the faulty vehicle, thereby driving the warning sign to move in the direction of the faulty vehicle, the valve core (7) is pulled out, the airbag (2) is deflated, and the auxiliary hinge plate (11) is rotated around the hinge shaft (3) so that the auxiliary hinge plate (11) covers the main hinge plate (10), and returns to the initial state;

[0018] The traction rope (6) is provided with a scale, and the distance the warning sign moves can be judged by the scale, so as to control the distance at which the warning sign is placed;

[0019] The airbag (2) is designed as a triangular pyramid structure. Compared with a triangular structure, when the airbag (2) is inflated, the triangular pyramid structure can provide warnings at multiple angles, thereby avoiding the deflection of the warning sign and affecting the reflective effect of the warning sign;

[0020] The main hinge plate (10) and the auxiliary hinge plate (11) are combined to form a triangular plate, so that the main hinge plate (10) and the auxiliary hinge plate (11) cooperate to form a foldable structure. The foldable structure occupies a small area and is easy to carry.

[0021] The design of the suction cup (5) enables the suction cup (5) to be attached to the faulty vehicle. When the warning sign is no longer in use, the driver of the faulty vehicle can directly remove the suction cup (5) and pull the traction rope (6) through the suction cup (5) to retract the warning sign, without the need for the driver of the faulty vehicle to go to the location of the warning sign to retract it.

[0022] The design of equidistantly arranged rope buckles on the towing rope (6) enables the driver of the faulty vehicle to first determine the approximate distance of the warning sign through the rope buckles, and then to know the specific distance through the scale on the towing rope (6);

[0023] The design of the inwardly recessed middle portion of the coil roller (9) can limit the position of the traction rope (6), thereby preventing the traction rope (6) from being offset and wound around the support frame (8), thereby preventing the traction rope (6) from causing a jam on the coil roller (9);

[0024] The main hinge plate (10) is provided with a counterweight at the bottom, and the auxiliary hinge plate (11) is provided with a counterweight at the bottom, so that the weight of the warning sign can be increased to prevent the warning sign from being blown by the airflow of passing vehicles, thereby affecting the warning effect of the warning sign;

[0025] The air pump (4) and the air bag (2) are designed to cooperate, the air pump (4) inflates the air bag (2) through the valve core (7), the air bag (2) expands, and is fully propped up to form a triangular prism-shaped structure. The air bag (2) is made of reflective material and can reflect all-round light sources. When the warning sign is deflected, the triangular pyramid-shaped structure can avoid affecting the reflectivity of the warning sign due to the deviation.

[0026] The design of the coordination between the traction rope (6) and the coil roller (9) enables the driver of the faulty vehicle to directly pull the traction rope (6) after use, and the traction rope (6) pulls the coil roller (9), thereby retracting the warning sign. The driver of the faulty vehicle does not need to go to the location where the warning sign is placed to retrieve the warning sign, thereby enhancing the safety of the driver of the faulty vehicle.

[0027] The purpose is to control the distance at which the warning sign is placed, enhance the reflective effect of the warning sign through the triangular pyramid structure, and be foldable and occupy a small area.
