[0026] An adjustable movable guardrail includes a first fixed rod 1, with support columns 101 at both ends of the first fixed rod 1, a support tube 102 at one end of each support column 101, a counterweight 103 near the bottom end of the support tube 102, a second fixed rod 104 between the two counterweights 103, a plurality of oblique limiting rings 105 at the bottom end of the first fixed rod 1, a plurality of positive limiting rings 106 at the top end of the second fixed rod 104, a plurality of limiting holes 2 symmetrically arranged on both sides of the support column 101, and a threaded hole 201 near the top end of the support tube 102, with a threaded rod 2 inside the threaded hole 201. 02. One end of the threaded rod 202 is equipped with a positioning rod 203. Near the top of the support column 101, a fixing cylinder 3 is provided. The inner side wall of the fixing cylinder 3 is equipped with a compression spring 301. A limiting rod 302 is passed through the inside of the compression spring 301. One end of the limiting rod 302 is equipped with a limiting plate 303. One end of the limiting rod 302 is equipped with a pull plate 304. A guardrail protection component 107 is provided between the positive limiting ring 106 and the oblique limiting ring 105. A mesh protection component 108 is also provided between the positive limiting ring 106 and the oblique limiting ring 105. Depending on the site conditions, fixing rods of different lengths are carried. After arriving at the site, the first set of counterweights is assembled first. After placing the counterweight 103 in a suitable position, insert the support tube 102. If the terrain is suitable, the position of the counterweight 103 can be further defined by bolts passing through the mounting holes. Then, insert the support column 101 into the support tube 102 and align the positioning rod 203 with the limiting hole 2. Then, rotate the threaded rod 202, which engages with the threaded hole 201 to limit the height between the support column 101 and the support tube 102. After that, insert one end of the first fixing rod 1 and the second fixing rod 104 into their respective receiving cavities. Then, assemble the second set of counterweights and insert the other end of the fixing rods into the receiving cavities. Insert the second set of receiving cavities. After the first fixing rod 1 is inserted into the receiving cavity, the pull plate 304 can be released. At this time, the compression spring 301 extends from the contracted state, and the limiting rod 302 is inserted into the positioning hole to limit the position between the first fixing rod 1 and the support column 101. At this time, the overall frame is completed. The positions between the positive limiting ring 105 and the oblique limiting ring 105 are opposite. Depending on the site conditions, the guardrail protection component 107 or the mesh protection component 108 can be used. The hooks can be assembled with the positive limiting ring 106 and the oblique limiting ring 105 respectively. The guardrail spacing can be controlled by itself. The whole is detachable for easy transportation and the assembly process is simple.

[0027] The guardrail protection component 107 includes a large sleeve 401, a small sleeve 402, a first tension spring 403, and a first hook 404. The small sleeve 402 can slide inside the large sleeve 401, and a limiting block is provided inside the small sleeve 402. A limiting groove is provided inside the large sleeve 401 to prevent the large sleeve 401 and the small sleeve 402 from completely falling apart. Two sets of first tension springs 403 are provided. One end of the first tension spring 403 is fixedly connected to the large sleeve 401 and the small sleeve 402 respectively, and the other end of the first tension spring 403 is connected to the first hook 404. The guardrail part can be extended and adjusted as needed, increasing the flexibility and applicability of the guardrail. The mesh protection component 108 includes a mesh protection net 501. The four corners of the mesh protection net 501 are provided with second tension springs 502. One end of the second tension spring 502 is provided with a second hook 503, which provides an additional protective layer for the guardrail and can effectively prevent small objects or people from falling through the gaps in the guardrail. The four corners of the mesh protective net are connected to the main body of the fence via a second tension spring and a second hook, ensuring the stability of the mesh protective net and facilitating installation and disassembly. The support column 101 and the counterweight block 103 have internal cavities for housing the ends of the first fixing rod 1 and the second fixing rod 104, making the fence more compact during disassembly or transportation and reducing space occupation. This design also facilitates the assembly and disassembly process of the fence, improving work efficiency. The two ends of the support column 101 have positioning holes for matching with the limiting rod 302. The positioning rod 203 matches the limiting hole 2, facilitating the fixing position after the support column 101 has been adjusted in height. The support tube 102 and the counterweight block 103 are connected by an embedded connection. The four corners of the bottom end of the counterweight block 103 have mounting holes for further defining the position of the counterweight block.

[0028] The working process of this utility model is as follows: When using this adjustable movable guardrail, firstly, depending on the site conditions, carry fixed rods of different lengths. Upon arrival at the site, first assemble the first set of counterweights 103 and support tubes 102. After placing the counterweights 103 in a suitable position, insert them into the support tubes 102. If the site terrain is suitable, the position of the counterweights 103 can be further defined by bolts passing through the mounting holes. Then, insert the support column 101 into the support tube 102 and align the positioning rod 203 with the limiting hole 2. Then, rotate the threaded rod 202, which engages with the threaded hole 201 to define the height between the support column 101 and the support tube 102. Afterward, separate one end of the first fixed rod 1 and the second fixed rod 104. Do not insert into their respective receiving cavities. Then assemble the second set of counterweights. Insert the other end of the fixing rod into the second set of receiving cavities. After the first fixing rod 1 is inserted into the receiving cavity, the pull plate 304 can be released. At this time, the compression spring 301 extends from the contracted state. The limiting rod 302 is inserted into the positioning hole to limit the position between the first fixing rod 1 and the support column 101. At this time, the overall frame is completed. The positions between the positive limiting ring 105 and the oblique limiting ring 105 are opposite. Depending on the site conditions, the guardrail protection component 107 or the mesh protection component 108 can be used. The hooks are assembled between the positive limiting ring 106 and the oblique limiting ring 105 respectively. The guardrail spacing can be controlled by the user. The whole is detachable for easy transportation. The assembly process is simple.
