[0019] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0020] like Figure 1~Figure 2As shown, a guardrail that is easy to replace and maintain includes a frame 1 and a wire mesh 2. A first shaft rod 3 and a second shaft rod 4 that are relatively arranged and rotatable are respectively installed in the frame 1, and a sprocket 302 is installed on one end of the first shaft rod 3 and the second shaft rod 4. The sprockets 302 on the first shaft rod 3 and the second shaft rod 4 are connected by a chain 303, so that the first shaft rod 3 and the second shaft rod 4 rotate synchronously. A strip hole 301 is set in the first shaft rod 3 and the second shaft rod 4; a locking screw 101 is installed on the frame 1 for locking the first shaft rod 3. The wire mesh 2 is placed in the frame 1, and the two ends of the wire mesh 2 are respectively connected at the relative positions of the two bar holes 301. By rotating the first shaft rod 3, the first shaft rod 3 drives the second shaft rod 4 to rotate synchronously under the connection of the chain 303; the wire mesh 2 is located between the first shaft rod 3 and the second shaft rod 4, and the synchronous rotation of the first shaft rod 3 and the second shaft rod 4 causes the two ends of the wire mesh 2 to be pulled apart, thereby putting the wire mesh 2 in a taut state. The wire mesh 2 is fixed by locking the rotating first shaft rod 3 with the locking screw 101, and the second shaft rod 4 is synchronously locked with the first shaft rod 3 under the connection of the chain 303. Then the quick installation of the wire mesh 2 is completed, and the wire mesh 2 can be loosened by loosening the locking screw 101 and reversing the first shaft rod 3. For the temporary and quick installation of the isolation railing or the replacement of the damaged wire mesh 2, the convenience of disassembly and installation is higher. Secondly, the steel mesh 2 can be disassembled and installed on site at the construction site, so the frame 1 and the steel mesh 2 can be transported separately during transportation, which makes transportation more convenient and reduces the damage rate.

[0021] like Figure 3~Figure 4 As shown, further, a conical head 305 is provided in the strip hole 301. When both ends of the wire mesh 2 are clamped in the strip hole 301, the conical head 305 provides more stress points during the tightening process of the wire mesh 2, so that the fixation of the wire mesh 2 is more stable.

[0022] Preferably, the first shaft rod 3 and the second shaft rod 4 are horizontally installed in the upper end and the lower end of the frame 1 respectively; the locking screw 101 is installed on the top of the frame 1. The first shaft rod 3 and the second shaft rod 4 are installed horizontally, so that the locking screw 101 can be installed on the top of the frame 1 to lock the first shaft rod 3. After the frame 1 is installed, the two sides often need to be spliced ​​with other frames 1. The locking screw 101 is located at the top of the frame 1 to facilitate the disassembly of the wire mesh 2.

[0023] Conical rods 6 arranged in a vertical direction are respectively installed at both ends of the bottom of the frame 1, and the conical rods 6 are used to quickly tighten the guardrail.

[0024] like Figure 5As shown, further, one end of the first shaft rod 3 passes through the frame 1, and a rectangular hole 304 is provided on the end of the first shaft rod 3. The rectangular hole 304 is provided on the first shaft rod 3, and the rotation adjustment of the first shaft rod 3 is completed by inserting the rectangular rod 501 of the rocker 5 into the rectangular hole 304.
