[0022] See also Figure 1 to Figure 4 An assembled guardrail for highway road construction includes a column 1, a base 2 is fixedly connected to the bottom of the column 1, and a base 2 9 is fixedly connected to the bottom of the column 6. The base 1 2 and the base 2 9 are placed at a designated work site, and a stable supporting effect of the column 1 and the column 6 can be achieved.

[0023] A fixing mechanism 3 is provided on the outer side of the column 1.

[0024] The fixing mechanism 3 includes a threaded column 301, and one end of the threaded column 301 is fixedly connected to the outer surface of the column 1, the outer surface of the threaded column 301 is threadedly connected with a rotary sleeve 302, and the outer surface of the rotary sleeve 302 is provided with a circle of convex strips, which is convenient for the operator to rotate the rotary sleeve 302 with his fingers, and is more labor-saving. The other end of the threaded column 301 is fixedly connected with an insertion rod 303, and the insertion rod 303 is inserted into the threaded barrel 404 to limit the other end of the connecting member 4, thereby improving the stability during connection.

[0025] Insert the insert rod 303 into the threaded barrel 404, and then rotate the rotary sleeve 302 so that the rotary sleeve 302 is threadedly connected with the outer surface thread of the threaded barrel 404, thereby fixing the threaded column 301 and the threaded barrel 404, thereby achieving a quick fixing effect on the other end of the connecting member 4.

[0026] A connecting member 4 is provided on one side of the column 1, and the connecting member 4 includes a connecting rod 401, one end of which is fixedly connected to a T-shaped slider 402, and the T-shaped slider 402 slides with the T-shaped slide groove 7, and the T-shaped slide groove 7 can limit the T-shaped slider 402, and a socket 2 403 is opened inside the T-shaped slider 402.

[0027] The other end of the connecting rod 401 is fixedly connected with a threaded barrel 404 , the outer surface of the threaded barrel 404 is threadedly connected with the inner wall of the rotary sleeve 302 , and the interior of the threaded barrel 404 slides with the outer surface of the insert rod 303 .

[0028] A limiting mechanism 5 is provided on the front side of the connecting rod 401 .

[0029] The limiting mechanism 5 includes a connecting plate 501, and the outer surface of the connecting plate 501 is fixedly connected to the outer surface of the connecting rod 401, the interior of the connecting plate 501 is slidably connected with a second plug rod 502, the second plug rod 502 is plugged into the interior of the socket 1 8, the second plug rod 502 is plugged into the interior of the second socket 403, and the outer surface of the second plug rod 502 is fixedly connected with a pull block 503.

[0030] The outer surface of the second insertion rod 502 is sleeved with an elastic member 504. The elastic member 504 is made of a spring. It deforms when subjected to force and stores a certain amount of potential energy. When the force is reduced, the potential energy is released to restore the deformation. One end of the elastic member 504 is fixedly connected to the outer surface of the connecting plate 501, and the other end of the elastic member 504 is fixedly connected to the outer surface of the pull block 503.

[0031] By pulling the pull block 503, the second insertion rod 502 can be driven to move along. At the same time, the pull block 503 will stretch the elastic member 504, which will cause the elastic member 504 to deform and store a certain potential energy. After releasing the pull block 503, the deformed elastic member 504 will drive the pull block 503 and the second insertion rod 502 to move in the opposite direction, thereby achieving a rapid reset effect of the pull block 503 and the second insertion rod 502.

[0032] The outer surface of the connecting rod 401 is slidably connected to the column 2 6, and a T-shaped groove 7 is provided inside the column 2 6.

A socket 1 8 is provided inside the column 2 6, and the socket 1 8 penetrates into the interior of the T-shaped groove 7. There are two groups of sockets 8, and the holes in each group are arranged at equal distances.

[0033] Working principle: When the utility model is in use, firstly, the base 1 2 and the base 2 9 are placed at the designated working location, at which time, the stable supporting effect of the column 1 1 and the column 2 6 can be achieved, and then the T-shaped slider 402 slides into the T-shaped slide groove 7 from top to bottom, and at the same time, the pull block 503 needs to be pulled in the direction away from the column 2 6, at which time, the plug rod 2 502 can be driven to move with it, and at the same time, the pull block 503 will stretch the elastic member 504, thereby causing the elastic member 504 to deform and store a certain potential energy, and when the T-shaped slider 402 moves to the designated position, the pull block 503 can be released, and at this time, the deformed elastic member 504 will drive the pull block 503 and the plug rod 2 502 to move in the opposite direction, so that the plug rod 2 502 can be quickly inserted into the socket 1 8 and the socket 2 403, thereby achieving the fixed limit of the T-shaped slider 402, thereby achieving a connection of the connector 4. The screw cap 302 is screwed onto the outer surface of the screw cap 404 to fix the screw column 301 and the screw cap 404, thereby achieving a quick fixing effect on the other end of the connecting member 4. No tools are required during installation, and the assembly process is simple and convenient. When disassembly is required, the screw cap 302 can be rotated in the opposite direction to release the limit fixation of the screw cap 404, and then the pull block 503 can be pulled to drive the plug rod 2 502 to be pulled out from the socket 2 403 and the socket 1 8 to release the limit fixation of the T-shaped slider 402. Then, the screw cap 302 is horizontally moved away from the connecting member 4 to pull the plug rod 303 out of the threaded barrel 404, and finally the connecting member 4 is pulled upward to make the T-shaped slider 402 disengage from the T-shaped slot 7 to complete the disassembly.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
