[0031] In the above technical solution, the warning bar is folded by a telescopic rod.

[0032] Reference Figure 2-3 The telescopic rod includes an inner tube 3 and an outer tube 2 slidably sleeved on the outer wall of the inner tube 3. The bottom end of the inner tube 3 is rotatably set on the top of the lower cross bar 4. The top of the outer tube 2 is fixedly provided with a rotating shaft 10. The outer wall of the rotating shaft 10 is rotatably sleeved with a connecting bottom plate 18, and the connecting bottom plate 18 is fixedly set at the bottom of the upper cross bar 1.

[0033] In the above technical solution, the warning bar is folded to Figure 2 status.

[0034] Reference Figure 3-4, at least one fixing component, the fixing component is arranged inside the telescopic rod, the fixing component includes an inner rod 12 and a U-shaped plate 8, the U-shaped plate 8 is located inside the rotating shaft 10, the U-shaped plate 8 is slidably arranged inside the rotating shaft 10, and the two ends of the U-shaped plate 8 pass through the outside of the rotating shaft 10, the outer walls on both sides of the connecting bottom plate 18 are provided with bayonet holes 9, and the two ends of the U-shaped plate 8 are respectively matched with the two bayonet holes 9;

[0035] In the above technical solution, when the two ends of the U-shaped plate are located at the bayonet 9 on the connecting bottom plate 18, the upper cross bar 1 and the outer cylinder 2 can rotate, otherwise they cannot rotate.

[0036] Reference Figure 3-4 A sliding cavity is provided at the top of the inner cylinder 3, and an inner rod 12 is slidably arranged inside the sliding cavity, a top end of the inner rod 12 passes through the rotating shaft 10, and a top end is fixedly arranged at the bottom of the U-shaped plate 8;

[0037] In the above technical solution, the movement state of the U-shaped plate 8 is achieved by controlling the inner rod 12 .

[0038] Reference Figure 3-4 The fixing assembly further includes a compression spring 14 disposed inside the sliding cavity, and two ends of the compression spring 14 are respectively fixedly disposed at the bottom of the inner rod 12 and an inner wall of one side of the sliding cavity;

[0039] The fixing assembly also includes an elastic plate 13 fixedly arranged on one side of the outer wall of the inner tube 3, and a clamping groove 11 matching with the elastic plate 13 is formed on one side of the inner wall of the outer tube 2 close to the elastic plate 13;

[0040] In the above technical solution, when unfolding the folded state in actual use, hold the upper cross bar 1 and lift it up obliquely to the top of the lower cross bar 4 (at this time, the U-shaped plate 8 located inside the rotating shaft 10 is not engaged with the bayonet 9 connecting the bottom plate 18, so that the upper cross bar 1 and the outer cylinder 2 can rotate), and then continue to lift the upper cross bar 1 upward, so that the outer cylinder 2 and the inner cylinder 3 are extended, and the inner rod 12 inside the inner cylinder 3 is subjected to the force of the compression spring 14 and moves upward with the outer cylinder 2 (the inner rod 12 and the U-shaped plate 8 are fixedly arranged so that the U-shaped plate 8 is still located at the top and is not engaged with the bayonet 9). When the outer cylinder 2 and the inner tube 3 are extended to the final length, the compression spring 14 can no longer push the inner rod 12 upward, so that the U-shaped plate 8 moves downward relatively, so that the two ends of the U-shaped plate 8 are engaged with the bayonet 9, so that the upper cross bar 1 and the outer tube 2 cannot rotate. At this time, the elastic support plate 13 will also be separated from the inside of the clamping groove 11 and deformed, so that it temporarily supports the outer tube 2, so that the outer tube 2 and the inner tube 3 cannot be shortened, so that after the upper cross bar 1 is lifted and unfolded, the warning bar can automatically fix it, so that it can be folded and stored when not in use, and can be easily carried and quickly unfolded when in use.

[0045] In the above technical solution, by setting the L-shaped blocks on the outer tube 2 and the inner tube 3, it is possible to insert multiple warning plates 5 with different information and to facilitate replacement when the warning bar is unfolded. Moreover, since the second L-shaped block 16 passes through the outer tube 2 through the vertical hole, the warning plate 5 will replace the elastic support plate 13 to support the outer tube 2, thereby achieving the effect of stabilizing the warning bar.

[0046] refer to Figure 2 The warning component also includes an L-shaped plate 7 fixedly arranged on the upper cross bar 1 and the lower cross bar 4 on the side away from the first L-shaped block 6 through connecting plates, and the two L-shaped plates 7 are respectively matched with the two L-shaped grooves 15 of the warning plate 5.

[0047] In the above technical solution, the warning plate 5 can be fixed in a limited position when in a folded state so as not to be randomly unfolded.

[0048] In order to prevent tipping, the warning bar in the utility model can be installed with a base at the bottom of the lower cross bar 4, and the connection method between the two warning bars is mostly to install plates with holes on both sides and then connect them by bolts, etc., which is basic common sense in this field and will not be described in detail.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
