[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] A folding guardrail mechanism 3 is provided between the two quick connection mechanisms 2. The folding guardrail mechanism 3 is used to connect the two upright posts 1 and play a protective role.

[0032] An anti-collision mechanism 4 is provided on one side of the folding guardrail mechanism 3, and the anti-collision mechanism 4 is used to alleviate the impact on the guardrail.

[0033] In an optional embodiment: a support foot 101 is provided at the bottom of the column 1 .

[0034] In an optional embodiment: the side wall of the column 1 is fixedly connected with a mounting seat 201. The mounting seat 201 is internally slidably connected with a mounting joint 202, a fixing groove 203 is provided at the bottom of the mounting joint 202, a sliding groove 204 is provided inside the mounting seat 201 just below the fixing groove 203, a clamping block 205 is slidably connected inside the sliding groove 204, a pull rod 206 is slidably connected to the bottom of the mounting seat 201, the top of the pull rod 206 is fixedly connected to the middle of the clamping block 205, and a first spring 207 is provided between the bottom of the clamping block 205 and the inner bottom of the sliding groove 204.

[0035] It should be noted that when installing the guardrail, the mounting joint 202 on one side of the upper cross bar 301 and the lower cross bar 305 is aligned with the mounting seat 201 and inserted, so that the mounting joint 202 pushes the block 205 to squeeze the first spring 207, so that when the fixing groove 203 is aligned with the block 205, the first spring 207 is released to push the block 205 into the fixing groove 203, thereby achieving the effect of quickly fixing the upper cross bar 301 and the lower cross bar 305. At this time, the mounting seat 201 on the other column 1 is aligned with the mounting joint 202 on the other side and inserted, so as to achieve the effect of quickly installing the guardrail body. Not only is the installation convenient, time-saving and labor-saving, but the components can also be disassembled during transportation for easy carrying.

[0036] In an optional embodiment: the folding guardrail mechanism 3 includes an upper cross bar 301 and a lower cross bar 305, the bottom of the upper cross bar 301 is fixedly connected to the first rotating seat 302, the inside of the first rotating seat 302 is rotatably connected to the first rotating rod 303, the bottom of the first rotating rod 303 is rotatably connected to the second rotating seat 304, the bottom of the second rotating seat 304 is fixedly connected to the lower cross bar 305, the first rotating seat 302, the first rotating rod 303 and the second rotating seat 304 are arranged equidistantly, and the two sides of the upper cross bar 301 and the lower cross bar 305 are fixedly connected to the mounting joint 202.

[0037] It should be noted that, by setting the first rotating seat 302, the first rotating rod 303 and the second rotating seat 304, the folding guardrail mechanism 3 can be folded, which is more convenient for carrying and storage. When the two sides of the upper cross bar 301 and the lower cross bar 305 are fixedly connected to the column 1 under the action of the quick connection mechanism 2, the first rotating rod 303 between the upper cross bar 301 and the lower cross bar 305 can no longer rotate, thereby playing a normal protective role.

[0038] In an optional embodiment: the side walls of the two columns 1 are respectively fixedly connected to two fixed cylinders 401, the upper two fixed cylinders 401 are internally slidably connected with upper sliding bars 402, the lower two fixed cylinders 401 are internally slidably connected with lower sliding bars 403, a connecting rod 404 is fixedly connected between the upper sliding bars 402 and the lower sliding bars 403, a sliding sleeve 405 is slidably connected on the surfaces of the upper sliding bars 402 and the lower sliding bars 403, a side wall of the sliding sleeve 405 is fixedly connected with a third rotating seat 406, the inside of the third rotating seat 406 is rotatably connected with a second rotating rod 407, one side of the second rotating rod 407 is fixedly connected with a fourth rotating seat 408, one side of the fourth rotating seat 408 is fixedly connected with a baffle 411, the surface of the upper sliding bar 402 is fixedly connected with a fixing ring 409, and a second spring 410 is provided between the side of the sliding sleeve 405 close to the fixing ring 409 and the side wall of the fixing ring 409.

[0039] It should be noted that when the upper cross bar 301 and the lower cross bar 305 are installed, the upper slide bar 402 and the lower slide bar 403 can be quickly inserted and installed together with the folding guardrail mechanism 3 after both sides are inserted into the fixing tube 401. When the front of the guardrail is impacted by external force, the external force will first collide with the baffle 411, so that the baffle 411 pushes the sliding sleeve 405 through the fourth rotating seat 408, the second rotating rod 407 and the third rotating seat 406, so that the sliding sleeve 405 squeezes the second spring 410 under the pushing action. The other side of the second spring 410 is fixed under the action of the fixing ring 409, so the second spring 410 will be compressed when the sliding sleeve 405 is pushed, so that the external impact on the baffle 411 is buffered by the elastic force of the second spring 410. After the external force stops, the second spring 410 resets and pushes the sliding sleeve 405 to reset, so that the sliding sleeve 405 pushes the baffle 411 to reset through the third rotating seat 406, the second rotating rod 407 and the fourth rotating seat 408, thereby achieving an anti-collision effect and protecting the guardrail body.

[0040] In an optional embodiment, the upper sliding rod 402, the lower sliding rod 403 and the connecting rod 404 are in an I-shape.

[0041] It should be noted that the I-shape can connect the upper slide bar 402 and the lower slide bar 403 into a whole, thereby improving the overall strength of the anti-collision mechanism 4 under the action of the connecting rod 404 and the fixed tubes 401 on both sides, which is beneficial to the anti-collision effect of the anti-collision mechanism 4.
