Examples

An assembled rail guard as shown in fig. 1 and 2, including railing subassembly 2 and the pole setting 1 that sets up respectively in railing subassembly both sides, pole setting 1 includes well core rod 11 and cover and establishes connecting pipe 12 on well core rod, is provided with a plurality of spread grooves 121 along circumference on the connecting pipe 12 lateral wall, spread groove 121 sets up along connecting pipe axis direction, 2 both ends of railing subassembly are provided with the connecting block 231 that matches with the spread groove, be connected through spread groove and connecting block between railing subassembly and the pole setting. Here, the connecting tube is rotationally connected to the central rod and the connecting tube is tolerance-fitted or interference-fitted to the central rod. The guardrail assembly is spliced, so that the guardrail can be quickly mounted and dismounted.

As shown in fig. 2, the connecting pipe 12 is provided with 6 connecting grooves 121 uniformly distributed along the circumferential direction thereof. Therefore, when the guard rail is assembled, the included angles of 180 degrees, 120 degrees and 60 degrees can be formed between two adjacent rail assemblies, so that the installation angle of the guard rail can be changed according to different shapes of fields to adapt to the requirements of different fields. The connecting groove and the connecting block are of trapezoidal section structures, so that the connection between the railing assembly and the vertical rod is more stable.
