For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, the embodiment of the present invention discloses a cantilever traffic sign plate anti-falling device, wherein the cantilever traffic sign plate 3 is arranged on the crossbeam 2, the crossbeam is supported by the column 1, and one end of the crossbeam is fixed on the column 1 through a flange. It includes a crossbeam clamp 5 and an elastic fastening strip 6, and the back of the cantilever traffic sign plate is provided with a plurality of connection strips 4 with preset intervals, and a plurality of crossbeam clamps and elastic fastening strips are respectively arranged on the corresponding connection strips, and the crossbeam clamp is installed on the outside of the crossbeam, and the crossbeam is connected to the traffic sign plate by bolts, and the elastic fastening strip is installed on the outside of the crossbeam, and the elastic fastening strip includes a bolt connection part, a protrusion protruding from the crossbeam, and a flat connection part arranged between adjacent protrusions, and the flat connection part is also provided with a screw hole, and the crossbeam is connected to the traffic sign plate by a bolt 7 passing through the bolt connection part and the screw hole of the flat connection part, and a bending spring of a preset length is arranged on the protrusion.

[0028] Furthermore, the crossbeam clamp and the elastic fastening strip are arranged at intervals.

[0029] Furthermore, the cross beams are divided into two, an upper cross beam and an lower cross beam, the elastic fastening strip has two protrusions, and the bending springs are respectively arranged above the upper cross beam and below the lower cross beam.

[0030] Furthermore, the distance between the bolt connection part and the upper end of the traffic sign plate on this side is smaller than the distance between the screw hole of the beam clamp and the upper end of the traffic sign plate on this side, and the distance between the screw holes on the two flat connection parts is smaller than the distance between the screw holes between the two beam clamps.

[0031] The elastic fastening strip is provided with a fastening hole 6.1 and a spring strip 6.2 for installation. As an optional embodiment, it may also include the following Figure 6 The fall-off warning device 8 shown in the figure is arranged above the column and includes an alarm light 8.1 and a receiver 8.2. The spring is equipped with a tension sensor. When the bending springs at both ends of the anti-fall device are stretched, Figure 7 As shown, the tension sensor built into the spring sends a signal that converts the tension information into an electrical signal and transmits it to the receiver, controlling the alarm light to be bright and flashing for warning.

[0032] Once encountering strong winds, the sign board surface is subjected to huge force, the fastening screws of the crossbeam clamp 5 loosen and fall off, and the crossbeam clamp cannot fix the sign board. At this time, the elastic fastening strip 6 as an anti-fall device plays a fixing role, and the bending springs at both ends are stretched to buffer the downward impact force of the sign board surface and prevent the traffic sign board from falling.

[0033] As an optional implementation, once the wind is strong and the sign board becomes loose, the tension sensor device is triggered and the warning device flashes, informing vehicles on the road to avoid danger. At the same time, it can attract the attention of patrol staff more quickly, and timely repair and handle it to prevent traffic accidents. The tension sensor built into the spring can effectively monitor the connection status of the board surface, and the warning device can effectively warn vehicles and patrol staff to prevent traffic accidents.

[0034] The structure that uses elastic fastening strips to assist the crossbeam clamp to hold the crossbeam tightly can not only provide additional support to prevent the sign from falling under extreme weather conditions, but also has a simple structure, easy installation and maintenance, and good compatibility, and is suitable for a variety of traffic sign boards of different specifications. In addition, the bending spring design in the anti-fall device can effectively absorb the impact force and reduce the displacement of the sign board, thereby reducing the risk of falling and improving the safety of road users.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
