Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment

[0021] Please refer to Figures 1 to 5, which is an embodiment of the present utility model. This embodiment provides a technical solution: a separation guardrail for urban construction, including column A100, column B200 and railing 300. Railings 300 are connected to the opposite sides of column A100 and column B200. By connecting column A100, column B200 and railing 300 in sequence, a whole guardrail can be formed. A connection component 400 is arranged between column A100 and column B200 to connect column A100 and column B200. The connection component 400 includes a fixed side plate 401, a sliding groove 402, a sliding connection plate 403, a spring 404, a plug post 406 and a slot 407. The fixed side plate 401 is fixed on one side of column A100, the sliding groove 402 is opened on one side of column B200. There are two sliding connection plates 403, which are distributed one above the other, and the ends extend into the sliding groove 402 movably. The two sliding connection plates 403 can move up and down, and the ends can rotate inside the sliding groove 402 to adjust the angle. The spring 404 is fixedly connected between the ends of the upper and lower sliding connection plates 403. The spring 404 can pull the upper and lower sliding connection plates 403 towards the middle. The plug post 406 is fixed on the opposite surfaces of the outer ends of the two sliding connection plates 403 and inserted into the slot 407 opened on the upper and lower surfaces of the fixed side plate 401 to complete the fixed connection between column A100 and column B200. The plug post 406 and the slot 407 are both octagonal structures when viewed from above. By rotating the sliding connection plate 403, the plug post 406 can be inserted into the slot 407 at different angles. In this design, the guardrail can be in a certain arc structure to adapt to the arc-shaped separation requirement. If disassembly is required, just separate the two sliding connection plates 403 and move the plug post 406 out of the slot 407.

[0022] In this embodiment, preferably, the connection component 400 further includes a fixed rod 405. The fixed rod 405 is fixedly connected between the upper and lower inner walls of the sliding groove 402. The inner end of the sliding connection plate 403 is movably connected to the fixed rod 405, enabling the sliding connection plate 403 to perform stable lifting and rotating movements. The spring 404 is sleeved on the surface of the fixed rod 405 to limit the spring 404 and prevent the spring 404 from bending.

[0023] In this embodiment, preferably, the connection component 400 further includes a connection pin 408. The connection pin 408 is slidably installed inside the plug post 406. The inner end of the connection pin 408 is threadedly connected to the inner wall of the slot 407. After the plug post 406 is inserted into the slot 407, the connection pin 408 can be tightened to improve the connection stability between the plug post 406 and the slot 407. The outer end of the connection pin 408 extends out of the sliding connection plate 403 and is fixedly connected with a pull ring, so that the connection pin 408 can be rotated and pulled.

[0024] In this embodiment, preferably, the connecting component 400 further includes an anti - detachment ring 409 and an anti - detachment inner groove 4010. The anti - detachment ring 409 is fixed on the surface of the connecting pin 408 and is movably connected with the anti - detachment inner groove 4010 formed inside the plug post 406. On the one hand, it plays a role in preventing detachment. On the other hand, personnel can directly pull the connecting pin 408 to pull the two sliding connecting plates 403.

[0025] In this embodiment, preferably, a splicing component 500 is connected between the column A100 and the railing 300. Through the splicing component 500, the fixed connection between the column A100 and the railing 300 can be realized. The splicing component 500 includes a docking block 501, a docking groove 502, a plug rod 503, and a vertical jack 504. The docking block 501 is fixed at the end of the railing 300 and is inserted into the inside of the docking groove 502 formed on the surface of the column A100 to complete the preliminary positioning connection. The vertical jack 504 is formed inside the column A100 and is in communication with the docking block 501. The plug rod 503 is arranged inside the vertical jack 504 and penetrates and inserts into the docking block 501. The bottom end of the plug rod 503 is threadedly connected with the vertical jack 504 to firmly fix the docking block 501 inside the docking groove 502 and complete the fixed connection between the column A100 and the railing 300. If disassembly is required, only the plug rod 503 needs to be removed. The splicing component 500 further includes a top groove 505 and a top cover 506. The top groove 505 is formed at the top of the column A100. The top end of the plug rod 503 is placed inside the top groove 505. The top cover 506 is sleeved on the top end of the column A100 to improve the installation stability of the plug rod 503. The same splicing component 500 is provided between the column B200 and the railing 300.
