[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a plug-in safety guardrail.

[0022] Reference Figure 1 The plug-in safety guardrail includes a main railing 1, a sleeve railing 2, and a plug-in structure 3.

[0023] In this embodiment of the application, the main column 1, the nested column 2, and the plug-in structure 3 can all be set to multiple groups.

[0024] Specifically, main column 1 is a vertical, rectangular railing.

[0025] Reference Figure 1 and Figure 2 The main fence 1 includes a fixed net 12 and posts 11. The fixed net 12 is a rectangular net, and there are two posts 11. The two posts 11 are of the same size and are parallel to each other. The fixed net 12 is fixed between the two posts 11. The fixed net 12 consists of two horizontal bars arranged vertically and multiple vertical posts fixed between the two horizontal bars. The posts 11 and the posts are all cylindrical. The two ends of the horizontal bars located above the fixed net 12 are fixedly connected to the upper ends of the two posts 11, and the two ends of the horizontal bars located below the fixed net 12 are fixedly connected to the lower ends of the two posts 11.

[0026] The two adjacent main columns 1 can be spliced ​​together by the plug-in structure 3, thereby achieving effective enclosure of construction sites, various buildings and public places.

[0027] Reference Figure 1 and Figure 2 The safety guardrail 2 includes a fixed post 21 and a telescopic guardrail 22. The telescopic guardrail 22 is located on one side of the fixed post 21, and its length is adjustable. The telescopic guardrail 22 can be bent along its long side to allow the safety guardrail to be installed at corners or bends in the installation site. The safety guardrail 2 and the main guardrail 1 can also be spliced ​​together through the plug-in structure 3, thereby effectively expanding the protection range of the safety guardrail and reducing its limitations.

[0028] Specifically, the telescopic fence 22 includes movable posts 221 and telescopic netting 222.

[0029] The movable column 221 is parallel to the fixed column 21, and the diameters of the movable column 221, the fixed column 21 and the column 11 are all the same; the telescopic barrier 222 is a rectangular barrier, one end of the telescopic barrier 222 is movable and retractable on the side wall of the movable column 221, and the other end is detachably connected to the side wall of the fixed column 21.

[0030] The plug-in structure 3 includes an integrally connected connecting part 31 and a plug-in part 32. The plug-in structure 3 is fixedly installed on the side of the fixed post 21 away from the telescopic fence 22 and on the upright post 11 of the main fence 1.

[0031] Preferred, refer to Figure 1 and Figure 2 The connecting part 31 is a rectangular strip, and the plug-in part 32 is a C-shaped arc plate. The plug-in structure 3 is integrally fixed to the side of the fixed post 21 away from the telescopic fence 22 through its connecting part 31, or integrally fixed to the outside of any post 11 of the main fence 1 through its connecting part 31. The movable post 221 and the post 11 are both plugged into the plug-in part 32. The inner peripheral walls at both ends of the plug-in part 32 are chamfered. The chamfer is used to guide the post 11 or the movable post 221 when it is inserted into the inside of the plug-in part 32. The width of the crossbar is smaller than the diameter of the post 11. The end of the crossbar is connected to the post 11 with an arc transition so that the post 11 can be inserted into the inside of the plug-in part 32.

[0032] When both the main fence 1 and the sleeve fence 2 are vertically arranged, the movable post 221 on the sleeve fence 2 can be inserted vertically into the C-shaped gap of the insertion part 32 on the main fence 1, and the outer wall of the movable post 221 can abut against the inner wall of the insertion part 32, thereby achieving a stable connection between the main fence 1 and the sleeve fence 2; and the operator can move the movable post 221 of the sleeve fence 2 according to the actual needs of the installation site, so that the telescopic fence 222 can be unfolded and enclosed with an appropriate arc, thereby providing adaptive enclosure and protection for the corners or turns of the installation site, and expanding the protection range of the safety guardrail.

[0033] Reference Figure 1 and Figure 2 When multiple sets of main railings 1 are provided, adjacent sets of main railings 1 can also be connected by a plug-in structure 3. Operators can use the plug-in structure 3 between adjacent sets of main railings 1 to insert the post 11 on one set of main railings 1 vertically into the plug-in part 32 on the outside of the post 11 of another set of main railings 1, thus achieving a stable connection between adjacent sets of main railings 1. Operators can also easily separate and disassemble the connected sets of main railings 1 by vertically pulling one set of post 11 away from the plug-in part 32 on the post 11 of another set of main railings 1, so that operators can repair or disassemble the damaged parts when the safety guardrail is damaged by impact.

[0034] Furthermore, to make the connection between the main column 1 and the nested column 2 / or between multiple sets of main columns 1 more stable, the plug-in structure 3 on the fixed column 21 and the plug-in structure 3 on the column 11 are both set to at least two sets.

[0035] Multiple sets of plug-in structures 3 on the fixed column 21 are arranged at equal intervals along the axis of the fixed column 21, and multiple sets of plug-in structures 3 on the column 11 are arranged at equal intervals along the axis of the column 11.

[0036] To facilitate the installation, removal, and maintenance of the telescopic fence 222, refer to Figure 2and Figure 3 The telescopic barrier 222 has a rotating shaft 223 rotatably connected to one end away from the movable column 221. The rotating shaft 223 is parallel to the movable column 221. The outer peripheral wall of the fixed column 21 has a groove 211 for the rotating shaft 223 to be inserted into along its axis. The two ends of the fixed column 21 have two locking holes 212 that are connected to the groove 211. The two ends of the rotating shaft 223 are respectively provided with two locking blocks 2231 for engaging with the upper and lower locking holes 212.

[0037] Two sets of mounting slots are provided at opposite ends of the rotating shaft 223. Two locking blocks 2231 are respectively installed in the two sets of mounting slots. Each set of mounting slots is provided with a spring. The extension and contraction direction of the spring is consistent with the axial direction of the rotating shaft 223. One end of each set of springs is fixedly connected to the rotating shaft 223 at the bottom wall of the mounting slot, and the other end is fixedly connected to the locking block 2231. The locking block 2231 is slidably connected to the end of the rotating shaft 223 along the axial direction of the rotating shaft 223. The end of the locking block 2231 away from the spring is arc-shaped.

[0038] Pressing the locking block 2231 towards the inside of the rotating shaft 223 allows the locking block 2231 to be placed into the mounting groove, thereby enabling the operator to embed the rotating shaft 223 into the recess 211. When the rotating shaft 223 is embedded into the recess 211, releasing the locking block 2231 allows the locking block 2231 to spring back under the elastic force of the spring and extend out of the mounting groove, while simultaneously engaging with the engaging hole 212 at the end of the fixed post 21, thereby stably embedding the rotating shaft 223 into the fixed post 21, ultimately achieving the fixation between the telescopic barrier 222 and the fixed post 21.

[0039] When it is necessary to disassemble the telescopic fence 222 and the fixed post 21, the operator can press the locking block 2231 towards the inside of the rotating shaft 223 and remove the rotating shaft 223 towards the outside of the fixed post 21, so as to easily remove the telescopic fence 222 from the fixed post 21, so that it can be repaired or disassembled when the guardrail is damaged by impact, making maintenance more convenient.

[0040] The implementation principle of the plug-in safety guardrail in this application embodiment is as follows: During use, the operator can use the plug-in structure 3 to splice the main guardrail 1 and the sleeve guardrail 2, thereby extending the protective length of the safety guardrail and achieving enclosure of the installation site; and according to the actual needs of the installation site, the movable column 221 of the sleeve guardrail 2 can be moved so that the telescopic net 222 can be unfolded and enclosed with an appropriate arc, thereby providing adaptive enclosure and protection for the corners or turns of the installation site and expanding the protection range of the safety guardrail; at the same time, when the main guardrail 1 or the sleeve guardrail 2 is damaged by impact, the operator can also use the plug-in structure 3 to separate the main guardrail 1 and the sleeve guardrail 2, and use the pivot 223 and the locking block 2231 to separate the fixed column 21 and the telescopic net 222, thereby effectively realizing the disassembly and maintenance of the main guardrail 1 and the sleeve guardrail 2.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
