[0002] Explosion-proof barriers are often used in places where public order needs to be maintained, such as performance squares, to isolate the crowd and prevent people from climbing over, trampling, and rioting.

[0003] During use of existing folding explosion-proof barriers, the support rods are usually upright on the equipment, making it difficult to stack and transport the explosion-proof barriers, resulting in the equipment taking up a large amount of space. At the same time, during long-term use of the equipment, the support rods are easily bent when multiple explosion-proof barriers are stacked, making the equipment inconvenient to disassemble and replace, resulting in reduced equipment performance.

[0009] As a preferred technical solution of the present invention: one end of the cylinder is fixed to the top of the round rod, and the other end of the second spring is fixed to the inner wall of the cylinder.

[0010] As a preferred technical solution of the present invention: the number of the limiting rods is vertical rods, and the vertical rods and limiting rods are distributed on both sides of the outer wall of the bracket and the outer wall of the support frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The foldable explosion-proof barrier rotates the support frame through external force, and the support frame drives the vertical rod to rotate, so that the vertical rod can be movable on the outer wall of the horizontal rod and overlap with the outer wall of the barrier rod, thereby enabling the support frame to drive the bottom plate to stand upright, thereby increasing the stability of the equipment.

[0024] In the above structure, when the equipment is in use, the support frame 8 is rotated by external force, and the support frame 8 drives the vertical rod 4 to rotate, so that the vertical rod 4 can move on the outer wall of the horizontal rod 3 and overlap with the outer wall of the baffle 5, thereby making the support frame 8 drive the bottom plate 9 to stand upright, thereby increasing the stability of the equipment. When the equipment is not in use, the support frame 8 is rotated by external force, and the support frame 8 drives the vertical rod 4 to rotate, so that the outer wall of the vertical rod 4 is separated from the outer wall of the baffle 5, thereby achieving folding and storage, which is convenient for personnel transportation.

[0025] In a preferred embodiment, one end of the first spring 12 is fixed to the outer wall of the pressure plate 11 , and the other end of the first spring 12 is fixed to the inner wall of the support frame 8 .

[0026] In the above structure, one end of the first spring 12 is fixed to the outer wall of the pressure plate 11, and the other end of the first spring 12 is fixed to the inner wall of the support frame 8. The limit rod 2 is pulled by external force, and the limit rod 2 drives the pressure plate 11 to compress the first spring 12, so that the limit rod 2 is separated from the inner wall of the vertical plate 10.

[0028] In the above structure, the inner wall of the square groove is adapted to the outer wall of the vertical plate 10, and the vertical plate 10 is placed on the inner wall of the support frame 8 by using external force, so that the vertical plate 10 and the support frame 8 are snap-fitted to achieve precise positioning and prevent the vertical plate 10 from being separated from the inner wall of the support frame 8.

The vertical plate 10 is placed on the inner wall of the support frame 8. The vertical plate 10 compresses the second spring 14 through the round rod 15, so that the round rod 15 is slidably connected to the inner wall of the cylinder 13, and then the round rod 15 uses the elastic force of the second spring 14 to resist the vertical plate 10, thereby preventing the vertical plate 10 from being installed offset.

When the vertical plate 10 and the bottom plate 9 are used for a long time and deformed, the vertical plate 10 and the bottom plate 9 are disassembled, assembled and replaced through the limit rods 2, which reduces the workload of personnel and saves time and effort.

[0033] Working principle: By placing the device on the ground, using external force to rotate the support frame 8, the support frame 8 drives the vertical rod 4 to rotate, so that the vertical rod 4 can move on the outer wall of the cross bar 3 and overlap with the outer wall of the barrier rod 5, so that the support frame 8 drives the bottom plate 9 to stand upright, increasing the stability of the device. The extension rod 6 drives the pedal 7 to extend and retract to the appropriate position to support the device. When the device is used for a long time, the device is deformed, and the external force pulls the limit rod 2, which drives the pressure plate 11 to compress the first spring 12, so that the limit rod 2 is disengaged. On the inner wall of the vertical plate 10, the vertical plate 10 can be quickly disassembled and replaced. The vertical plate 10 is placed on the inner wall of the support frame 8. The vertical plate 10 compresses the second spring 14 through the round rod 15, so that the round rod 15 can be slidably connected to the inner wall of the cylinder 13, and then the round rod 15 uses the elastic force of the second spring 14 to resist the vertical plate 10, avoiding the installation deviation of the vertical plate 10. The limit rod 2 is released by external force, and the elastic force of the first spring 12 is used to push the pressure plate 11 to drive the limit rod 2 to be inserted into the inner wall of the vertical plate 10, thereby realizing quick installation.
