Figure 1-3 As shown, it comprises a guardrail post 1, a crossbar 2 is fixed to the outer wall of the guardrail post 1, a vertical bar 3 is inserted and installed on the inner side of the crossbar 2, and is characterized in that a limiting mechanism 4 is arranged on the crossbar 2 and the vertical bar 3, and the limiting mechanism 4 is used to limit the connection between the crossbar 2 and the vertical bar 3;

[0031] The limiting mechanism 4 includes a transmission unit and a reset unit;

[0032] The transmission unit is used to limit the connection between the horizontal bar 2 and the vertical bar 3;

[0033] The reset unit is used to always provide the transmission unit with a thrust to one side;

[0034] The transmission unit includes a movable rod 401, a stop block 402, a limit block 403, and a limit slot 404;

[0035] The movable rod 401 is axially slidably installed on the top of the cross bar 2, and the movable rod 401 is used to synchronously drive the stop block 402 and the limit block 403 to move;

[0036] The stopper 402 is fixed to the outer wall of the movable rod 401, and the stopper 402 is used to receive the extrusion thrust from a vertical rod 3;

[0037] The limit block 403 is fixed on the outer wall of the movable rod 401, and the limit block 403 is used to be inserted into the inner part of the limit groove 404 to limit the vertical movement of the vertical rod 3;

[0038] The limiting groove 404 is provided on the outer wall of the vertical rod 3, and the limiting groove 404 is used to provide space for the limiting block 403 to enter;

[0039] The reset unit includes a push block 405, a positioning rod 406, and a spring 407;

[0040] The push block 405 is fixed at the bottom end of the movable rod 401 and extends to the inside of the cross bar 2. The push block 405 is used to give the spring 407 a squeezing force;

[0041] The positioning rod 406 is fixed inside the crossbar 2 and passes through the push block 405. The positioning rod 406 is used to provide guidance for the movement of the push block 405.

[0042] The two ends of the spring 407 are respectively clamped on the outer wall of the push block 405 and the inside of the guardrail column 1, and the spring 407 is used to provide a directional extrusion thrust for the push block 405.

[0043] In this embodiment: when using this device, the vertical rods 3 are inserted into the interior of the cross bar 2 one by one. During this process, the socket covered by the stopper 402 needs to be reserved for insertion last. When the other vertical rods 3 are inserted, the last one can be inserted. During the process of the last vertical rod 3 being inserted into the cross bar 2, the vertical rod 3 will contact the inclined surface of the stopper 402, giving the stopper 402 an extrusion force. The stopper 402 subjected to the extrusion force will synchronously drive the movable rod 401 to move, so that multiple limit blocks 403 fixed on the movable rod 401 move synchronously. The multiple limit blocks 403 are synchronously inserted into the limit grooves 404 on the outer walls of the vertical rod 3, and the multiple limit grooves 404 are limited. The movable rod 401 moves During the process, the push block 405 will be synchronously driven to move along the outer wall of the positioning rod 406, and the spring 407 will be applied with squeezing force until the last vertical rod 3 is fully inserted and the slot on the last vertical rod 3 is docked with the stop block 402. After docking, the stop block 402 enters the slot under the action of the spring 407 to complete the limiting of the stop block 402, and the moving distance of the stop block 402 is less than the initial position, so that the limit block 403 is still stuck in the limit slot 404, achieving the purpose of quickly docking the cross bar 2 and the vertical rod 3, reducing the welding steps, further improving the work efficiency, and avoiding the situation where the cross bar 2 and the vertical rod 3 become loose due to rust at the welding position, thereby improving the stability.

[0044] Please refer to Figure 1-Figure 3 The interior of the cross bar 2 is formed with a sliding groove for the axial movement of the push block 405. The outer wall of the push block 405 is generally in an "L"-shaped structure, and the outer wall of the positioning rod 406 is generally in a "T"-shaped state. The inner wall of the push block 405 matches the outer wall of the positioning rod 406. One end of the outer wall of the stop block 402 is in an inclined state. The stop block 402 in the initial unmoved state is located above the socket of the vertical rod 3 at the top of the cross bar 2. The outer wall of the limit block 403 matches the inner cavity of the limit groove 404. The outer wall of a vertical rod 3 is formed with a slot for the stop block 402 to enter, and the inner cavity length of the slot is less than the inner cavity length of the limit groove 404.

[0045] In this embodiment: through this structure, the movable rod 401 and the limit block 403 can be synchronously driven to move under the moving inclined surface of the stop block 402 during the force process, so that the limit block 403 is inserted into the limit groove 404 to limit the vertical rod 3, and because the moving distance of the stop block 402 during the resetting process is less than the distance of the limit block 403 inserted into the limit groove 404, the limit block 403 can still be inserted into the limit groove 404 after the stop block 402 is inserted.
