The snap assembly 4 is provided in multiple groups, and each two snap assemblies 4 form a group. Each set of buckle components 4 is symmetrically arranged up and down, and the buckle components 4 include a side fixed frame 401, the side fixed frame 401 is fixedly arranged on one side of the column 3, the bottom end of the side fixed frame 401 is fixedly provided with a reset spring 408, the other end of the reset spring 408 is fixedly provided with a rotating pad 407, the bottom end of the rotating pad 407 is rotatably provided with a buckle lock block 403, and the two sides of the buckle lock block 403 are slidably provided with vertical slide rails 402, and the vertical slide rails 402 are fixedly provided at the bottom end of the side fixed frame 401. A screw column 409 is provided through the side and slides therethrough. A sleeve 410 is provided on the outer side of one end of the screw column 409. The sleeve 410 is fixed to the top of the side fixed frame 401. A rope collecting disc 411 is provided on the top of the sleeve 410. A pull rope 412 is fixed on the outer side of the rope collecting disc 411. A torsion spring 413 is provided inside the sleeve 410. One end of the torsion spring 413 is fixed to the top of the side fixed frame 401. The other end of the torsion spring 413 is fixed to the outer side of the screw column 409. Both sides of the buckle lock block 403 are fixed. A slide groove 404 is provided, and the vertical slide rail 402 is slidably set on the inner side of the slide groove 404. A slope surface 406 is provided on one side of the snap lock block 403, and a threaded hole 405 is provided on the top of the snap lock block 403. The snap lock block 403 is threadedly connected to the screw column 409 through the threaded hole 405. The pull rope 412 is set through the column 3, and the pull rope 412 is slidably set on the inner side of the short slide cylinder 3011. One end of the pull rope 412 is fixedly provided with a limiting round block 4121, and the limiting round block 4121 is fixedly set on one side of the vertical connecting plate 2.

[0024] When installing the guardrail body 1, the cross bar 101 and the extended vertical column 102 are brought close to the snap assembly 4. The snap lock block 403 in the snap assembly 4 can smoothly pass through the extended vertical column 102 through the setting of the slope surface 406, and at the same time the snap lock block 403 will rise, and the snap lock block 403 in each group of snap assemblies 4 below will fall, the return spring 408 will be compressed, and the snap lock block 403 will slide along the vertical slide rail 402. When the snap lock block 403 passes through the extended vertical column 102, the snap lock block 403 will return to its original position due to the elastic force of the return spring 408, thereby being stuck on one side of the extended vertical column 102, thereby completing the installation between the guardrail body 1 and the column 3.

[0025] When disassembling the guardrail body 1 and the column 3, the handle 201 is pulled so that the vertical plate 2 can drive the pull rope 412 to be released, and the rope-collecting drum 411 will rotate, thereby driving the screw column 409 to rotate. The rotation of the screw column 409 will drive the buckle lock block 403 to rise, and the torsion spring 413 will shrink. At this time, the buckle lock block 403 in each group of buckle assemblies 4 will move away until the cross bar 101 and the extended vertical column 102 on one side of the guardrail body 1 can be taken out, and the handle 201 is released. The pull rope 412 will be rewound around the outside of the rope-collecting drum 411 by the elastic force of the torsion spring 413, and the screw column 409 can rotate in the opposite direction due to the elastic force of the torsion spring 413, so that the buckle lock block 403 can return to its original position, thereby achieving the effect of facilitating installation and disassembly and improving engineering efficiency.

[0026] See Figure 1 and Figure 2 A through hole is symmetrically provided on one side of the cross bar 101, and a guide column 301 is slidably provided on the inner side of the through hole. The guide column 301 is fixedly provided on one side of the column 3, and a foot seat 302 is fixedly provided at the bottom end of the column 3. A plurality of short slides 3011 are fixedly provided on both sides of the column 3. A vertical connecting plate 2 is provided on the other side of the column 3, and the vertical connecting plate 2 does not contact the column 3. A handle 201 is fixedly provided on the other side of the vertical connecting plate 2.

[0027] During installation, the guide column 301 can be inserted into the through hole for guidance, which reduces the installation accuracy and is beneficial to improving the installation efficiency. The setting of the foot 302 is to facilitate the guardrail to stand on the ground, and the foot 302 is made of concrete, which facilitates more stable standing. The setting of the short slide 3011 facilitates the sliding of the pull rope 412.

[0028] The working principle of the present invention is as follows: when installing the guardrail body 1, the crossbar 101 and the extension vertical column 102 are brought close to the buckle assembly 4, and the buckle locking block 403 in the buckle assembly 4 can smoothly pass through the extension vertical column 102 through the setting of the slope surface 406, and at the same time, the buckle locking block 403 will rise, and the buckle locking block 403 in each group of buckle assemblies 4 below will fall, and the return spring 408 will be compressed, and the buckle locking block 403 will slide along the vertical slide rail 402. When the buckle locking block 403 passes the extension vertical column 102, the buckle locking block 403 will return to its original position by the elastic force of the return spring 408, and thus be stuck on one side of the extension vertical column 102, thereby completing the installation between the guardrail body 1 and the column 3;

[0029] It should be noted that, taking the upper buckle assembly 4 as an example, when the buckle lock block 403 rises during installation, the screw column 409 and the rope-collecting drum 411 are driven to rise together, and the pull rope 412 is bent. Since the torsion spring 413 is arranged in a vortex shape, the torsion spring 413 can freely follow the deformation without affecting the use of the torsion spring 413. When the buckle lock block 403 returns to its original position, the other components will return to their original positions without affecting their use.

[0030] When disassembling the guardrail body 1 and the column 3, the handle 201 is pulled so that the vertical plate 2 can drive the pull rope 412 to be released, and the rope-collecting drum 411 will rotate, thereby driving the screw column 409 to rotate. The rotation of the screw column 409 will drive the buckle lock block 403 to rise, and the torsion spring 413 will shrink. At this time, the buckle lock block 403 in each group of buckle assemblies 4 will move away until the cross bar 101 and the extended vertical column 102 on one side of the guardrail body 1 can be taken out, and the handle 201 is released. The pull rope 412 will be rewound around the outside of the rope-collecting drum 411 by the elastic force of the torsion spring 413, and the screw column 409 can rotate in the opposite direction due to the elastic force of the torsion spring 413, so that the buckle lock block 403 can return to its original position, thereby achieving the effect of facilitating installation and disassembly and improving engineering efficiency.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
