During the warning process, the height can be stably adjusted as needed to prevent tilting. It can also realize the connection of multiple warning devices without the need for separate power supply, which greatly improves the convenience of use and application value of the warning device.

[0043] In one example of the present invention, a photovoltaic panel 26 is inserted into the longitudinal column 2 to absorb light energy during the day, and the photovoltaic panel 26 is connected to the storage battery and the inverter arranged inside the longitudinal column 2. A plurality of lamps 25 are arranged on both sides of the longitudinal column 2, and the lamps 25 are electrically connected to the storage battery for lighting in dim light conditions.

[0044] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the reverse extension mechanism 100 includes a fixed block 3, a driven gear 1 4, a driven gear 2 5, a double-sided gear plate 6, a rocker rod 1 7 and a rocker rod 2 8;

[0045] The fixing block 3 is installed at the top of the longitudinal column 2, and the two sides of the fixing block 3 are hinged with a swing rod 1 7 and a swing rod 2 8;

[0046] The interior of the fixed block 3 is a hollow structure, and a driven gear 1 4 and a driven gear 2 5 are rotatably installed in the fixed block 3.

[0049] like Figure 1 As shown, as another preferred embodiment of the present invention, the accommodating mechanism 200 includes an accommodating wall cabinet 9, a mounting slot 10 and a storage cavity 11;

[0050] The mounting groove 10 is provided in the swing rod 1 7 and the swing rod 2 8;

[0051] The storage cabinet 9 is installed between the longitudinal column 2 and the swing rod 1 7 , and between the longitudinal column 2 and the swing rod 2 8 . A storage cavity 11 communicating with the mounting groove 10 is also provided in the storage cabinet 9 .

[0052] In one embodiment of the present invention, the storage cabinet 9 is made of a transparent foldable material so that the warning content placed in the storage cabinet 9 can be observed from the outside, and during the extension of the swing arm 7 and the swing arm 8, the storage cabinet 9 automatically extends, and when the swing arm 7 and the swing arm 8 swing to a horizontal state, the storage cabinet 9 is in an unfolded state, and the displayed cardboard and the like can be passed through the installation slot 10 and fall into the storage cavity 11; in addition, when the storage cabinet 9 adopts a structure similar to the folding screen of a mobile phone, the warning content can be dynamically displayed when a processor is connected.

[0055] The positioning seat 12 and the clamping seat 13 are provided with through holes 14 with the same aperture, and are fixed by external plug-in columns 27 .

[0056] In one example of the present invention, when a plurality of warning devices are arranged in sequence, adjacent positioning seats 12 are plugged into the card seat 13, and when the through holes 14 on the positioning seats 12 and the card seat 13 are coaxial, the adjacent positioning seats 12 and the card seat 13 can be fixed by embedding an external plug-in column 27 into the through hole 14, and when the warning device is arranged vertically, a card seat 2 perpendicular to the card seat 13 can also be arranged on the side of the rocker arm 1 7 or the rocker arm 2 8 to form a rectangular enclosure.

[0057] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the bidirectional driving mechanism 400 includes a driving shaft 15, a driving screw 16, a bevel gear set 17, a screw sleeve 18, a movable rod 19 and a support 20;

[0058] The drive shaft 15 and the drive screw 16 are rotatably mounted in the fixed base 1, and the drive shaft 15 and the drive screw 16 are vertically distributed. The drive shaft 15 and the drive screw 16 are also connected by a bevel gear set 17. At the same time, the rotation direction of the drive screw 16 is adjusted as needed to ensure that the screw sleeves 18 on both sides move in opposite directions.

[0059] The screw sleeves 18 are arranged in pairs, and the screw sleeves 18 are respectively installed on the driving screws 16 on both sides. The top of the screw sleeve 18 is hinged with a movable rod 19, and the free end of the movable rod 19 is hinged with a support 20.

[0060] A driving motor 21 is installed on the fixed base 1 , and the driving motor 21 is connected to the driving shaft 15 through a coupling. A groove for the movable rod 19 to move is also provided on the fixed base 1 .

[0061] In one example of the present invention, when the height of the longitudinal column 2 needs to be adjusted, the drive motor 21 can be connected to an external controller and the external controller can control the rotation process. The drive motor 21 drives the drive shaft 15 to rotate along the fixed base 1 through a coupling. The drive shaft 15 drives the drive screws 16 on both sides to rotate through the bevel gear set 17. The drive screw 16 drives the screw sleeve 18 to move. The screw sleeve 18 drives the movable rod 19 and the support 20 to swing along the fixed base 1 and adjusts the position of the support 20 in the height direction.

[0064] The inclined rods 23 are symmetrically mounted on the upper surface of the transverse plate 22, and the top ends of the inclined rods 23 are fixedly connected to the longitudinal columns 2 to improve the structural stability.

[0065] The guide posts 24 are slidably mounted on both sides of the transverse plate 22 , and the bottom ends of the guide posts 24 are fixedly connected to the fixed base 1 to ensure the movement stability of the longitudinal posts 2 .

[0066] In one embodiment of the present invention, when the support 20 is lifted or lowered, the support 20 also pushes the horizontal plate 22 and the longitudinal column 2 to be lifted or lowered synchronously, and the support 20 also slides stably along the guide columns 24 on both sides.

[0067] In summary, when in use, the controller supplies power to the electric telescopic rod through the storage battery, and the electric telescopic rod pushes the double-sided toothed plates 6 to move in the height direction along the longitudinal column 2. Since the double-sided toothed plates 6 are meshed with the driven gear 1 4 and the driven gear 2 5 on both sides, the driven gear 1 4 and the driven gear 2 5 can be pushed to move in opposite rotation directions along the fixed block 3. Since the driven gear 1 4 is connected to the swing rod 1 7, and the driven gear 2 5 is connected to the swing rod 2 8, the swing rod 1 7 and the swing rod 2 8 swing in opposite directions along the fixed block 3, and swing to a horizontal position. The movement stops when the storage cabinet 9 is in the unfolded state, and the displayed cardboard can be dropped into the storage cavity 11 through the installation slot 10 to warn the construction work, and a baffle is installed on the top of the installation slot 10 to prevent rain, dust, etc. from entering the storage cavity 11 and affecting the clarity. The photovoltaic panel 26 absorbs light energy during the day. The photovoltaic panel 26 is connected to the storage battery and inverter arranged inside the longitudinal column 2, and is illuminated by the lamp 25 in dim light. When multiple warning devices are arranged together in sequence, the adjacent positioning seat 12 is plugged into the card seat 13, when the through holes 14 on the positioning seat 12 and the card seat 13 are coaxial, the external plug-in column 27 is embedded in the through hole 14, so that the adjacent positioning seat 12 and the card seat 13 can be fixed. When the driving motor 21 is working, the driving shaft 15 can be driven by the coupling to rotate along the fixed base 1, and the driving shaft 15 drives the driving screws 16 on both sides to rotate through the bevel gear set 17. The driving screw 16 drives the screw sleeve 18 to move, and the screw sleeve 18 drives the movable rod 19 and the support 20 to swing along the fixed base 1, and the support is adjusted. 20 is in the height direction, the horizontal plate 22 also pushes the horizontal plate 22, the longitudinal column 2, the swing rod 1 7, the swing rod 2 8 and the accommodating wall cabinet 9 to rise and fall synchronously, and adjusts the height of the warning content. The warning device is not only convenient for storage before and after the warning, but also saves transportation space and cost, and is easy to assemble. During the warning process, the height can be stably adjusted as needed to prevent tilting. It can also realize the connection work of multiple warning devices without the need for separate power supply, which greatly improves the convenience and application value of the warning device.
