Description

Technical Field

[0001] The present application relates to the technical field of road tow trucks, and in particular to a road closure warning device for road tow trucks. Background Art

[0002] A road tow truck, also known as a tow truck, road rescue truck, or towing truck, has multiple functions such as lifting, pulling, and lifting and traction. Tow trucks are mainly used for road breakdown vehicles, urban illegal vehicles, and emergency rescue.

[0003] When some major accidents or extreme weather occur, the highway needs to be closed. At this time, objects such as cones or warning signs need to be placed. The cones or warning signs not only take up the space of the tow truck, but also need to be loaded at a designated place, which is slow in timeliness. At the same time, the warning signs or cones are easily blown down by the wind, resulting in a poor warning effect.

[0004] Therefore, there is an urgent need to develop a warning device that is easy to carry and easy to warn. Utility Model Content

[0005] The purpose of the present application is to provide a road blocking warning device for a road tow truck to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present application provides a road blocking warning device for a road tow truck using the following technical solution:

[0007] A road closure warning device for a road tow truck comprises a carriage installed on the tow truck, storage slots are symmetrically fixed on both sides of the carriage, a warning mechanism is arranged in the storage slots, the warning mechanism comprises a plurality of load-bearing rods hinged in sequence, the plurality of load-bearing rods can be unfolded to form a straight line, a load-bearing rod close to one side of the storage slots is hinged in the storage slots, a latch is connected between adjacent load-bearing rods, a cavity is opened in the load-bearing rod, and a warning roller shutter is arranged in the cavity.

[0008] Preferably, in order to ensure a good warning effect, support rods are symmetrically and movably connected on both sides of the cavity, and the support rods can hold up the warning roller blind. The support rods can be placed in the cavity, and the warning roller blind is held up by the support rods. The warning range is large and is not easily affected by the environment.

[0009] The surface of the bearing rod is coated with a reflective layer.

[0010] Preferably, a cover plate is hinged on the side of the storage slot, and a box buckle is connected between the cover plate and the storage slot.

[0011] By adopting the above technical solution and providing a cover plate, the side of the storage slot can be sealed by using box buckles to prevent the load-bearing rod from slipping out and causing danger.

[0012] Preferably, the cover plate is threadedly connected with an anti-sway stud, and the anti-sway stud can abut against the side wall of the bearing rod.

[0013] By adopting the above technical solution, by providing anti-sway studs and using the anti-sway studs to press against the side walls of the bearing rods, collisions between the bearing rods can be avoided, thereby reducing the generation of noise.

[0014] The storage slot is threadedly connected with a locking stud at a hinged position corresponding to the bearing rod, and the locking stud can abut against the bearing rod.

[0015] To sum up, the present application includes at least one of the following beneficial technical effects: the road closure warning device for road tow trucks has a novel and compact structure. By integrating the warning device on the tow truck, it can be used anytime and anywhere, which is quick and convenient. It is unfolded through multiple sections of load-bearing rods to form a straight line, and the load-bearing rods are coated with a warning reflective layer, so the warning effect is good and is not easily affected by the environment. At the same time, the warning roller curtain is opened by using the support rod, so the warning range is large and the warning effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-2 This application is described in further detail.

[0020] The present application embodiment discloses a road blocking warning device for a road tow truck, referring to Figure 1-2, including a carriage 1 installed on a tow truck, storage slots 11 are symmetrically fixed on both sides of the carriage 1, and a warning mechanism is arranged in the storage slot 11. The warning mechanism includes three sections of load-bearing rods 2 hinged in sequence, and the load-bearing rod 2 close to the storage slot 11 is hinged in the storage slot 11, and the storage slot 11 is threadedly connected with a locking stud 111 near the hinge with the load-bearing rod 2, and the locking stud 111 can abut against the load-bearing rod 2, and a latch 3 is connected between adjacent load-bearing rods 2. The three sections of the load-bearing rod 2 can be unfolded to form a straight line, and a reflective layer is coated on the surface of the load-bearing rod 2, and a cavity 21 is opened in the load-bearing rod 2, and a warning roller shutter 4 is arranged in the cavity 21. Support rods 5 are symmetrically and movably connected on both sides of the cavity 21, and the support rods 5 can tighten the warning roller shutter 4. The warning roller shutter 4 is a conventional automatic roller shutter, and a reflective warning coating is printed on the roller shutter, and the support rod 5 can be placed in the cavity 21.

[0021] Reference Figure 1 A cover plate 6 is hinged on the side of the storage slot 11 , a box buckle 7 is connected between the cover plate 6 and the storage slot 11 , and an anti-sway stud 61 is threadedly connected to the cover plate 6 , and the anti-sway stud 61 can abut against the side wall of the bearing rod 2 .

[0022] By providing a cover plate 6, the side of the storage slot 11 can be sealed using the box buckle 7 to prevent the load-bearing rod 2 from slipping out and causing danger. At the same time, by providing an anti-sway stud 61 and using the anti-sway stud 61 to press against the side wall of the load-bearing rod 2, the load-bearing rods 2 can be prevented from colliding with each other, thereby reducing the generation of noise.
