Open-loop buckles 501, closed-loop buckles 502 and elastic clips 503 are arranged at both ends of the conversion cross bar 5. The open-loop buckles 501, closed-loop buckles 502 and elastic clips 503 are offset from each other by ninety degrees. The open-loop buckles 501, closed-loop buckles 502 and elastic clips 503 at the ends of the conversion cross bar 5 can be converted at will. There are four connection methods for the barrier cloth 4 in the middle of the conversion cross bar 5, and various types of barrier cloth 4 can be installed. Compared with the protective wall device in the prior art, the previous protective wall device and the barrier cloth 4 have only one installation method. According to the construction situation, if different types of 4 need to be built, it is also necessary to replace the connecting buckles on the frame accordingly.

[0033] like Figure 3As shown, the convenient grounding component includes a divergent bracket 301, the cross-section of the divergent bracket 301 is cross-shaped, and the bottom edge of the divergent bracket 301 is sharp, and the sharp edge width of the divergent bracket 301 is two millimeters. When installing the device, the divergent bracket 301 is attached to the ground, and then the chassis 3 is hit down with a hammer. The divergent bracket 301 will be hammered into the soil. The divergent bracket 301 has enhanced grip. Compared with the installation method of the prior art, the previous protective wall also needs to dig a groove on the ground first, and in order to reinforce the protective wall, it is necessary to add inclined legs to the protective wall, which makes the protective wall device occupy a larger area, and there is no need to use inclined legs when the divergent bracket 301 is inserted into the soil.

[0034] like Figure 1 , 2 As shown, the barrier cloth 4 includes a wire mesh layer and a plastic film layer, which are connected by gluing. Locking rings are provided at the four corners of the wire mesh layer, which buckle the open-loop buckles 501. The wire mesh layer reinforces the strength of the barrier cloth 4 to prevent the barrier cloth 4 from being torn over a large area. When it is windy, the wire mesh layer also serves as a skeleton of the plastic film.

[0035] like Figure 5 As shown, the expansion hanger assembly includes a lying groove 2, which is arranged on the side wall of the column 1, and a hanger 201 and a push rod 204 are arranged on the inner side of the lying groove 2. The ends of the hanger 201 and the push rod 204 are respectively rotatably connected to the inner side of the lying groove 2, and a resistance notch 202 is arranged on the side wall of the hanger 201. The end of the push rod 204 is inserted into the inner side of the resistance notch 202. A plurality of clothing hooks 203 are arranged on one side of the hanger 201. The clothing hooks 203 are evenly arranged in a straight line. The material is stainless steel, and a magnet block that can absorb the clothing hook 203 and the top rod 204 is arranged on the inner wall of the lying groove 2. When it is necessary to hang clothes on the device, the hanger 201 and the top rod 204 are pulled out, and then the end of the top rod 204 is inserted into the interference notch 202. The construction workers on site put the taken-off outer hook on the clothing hook 203. When the hanger 201 and the top rod 204 are put away, the magnet block inside the lying groove 2 absorbs the hanger 201 and the top rod 204, and the internal space of the column 1 is also fully utilized.

[0036] like Figure 5As shown, the sunshade component includes a cantilever beam bracket 6, a short tube 602 is provided at the port of the cantilever beam bracket 6, an annular chamber 604 matching the short tube 602 is provided at the top of the column 1, a wire groove 601 is provided at the top of the cantilever beam bracket 6, sunshade paper is buried on the inner side of the wire groove 601, and a rubber strip is inserted into the inner side of the wire groove 601, the short tube at the end of the cantilever beam bracket 6 is aligned with the annular chamber 604 and inserted, and then the sunshade paper is laid on the top of the cantilever beam bracket 6, and the rubber strip is inserted into the wire groove 601 to lock the sunshade paper, and the construction workers can sit under the sunshade paper to rest.

[0037] like Figure 5 As shown, a key bar 603 is provided on the inner side of the short tube 602, and a plurality of positioning grooves 605 are provided on the inner side of the annular chamber 604. The key bar 603 is inserted into one of the positioning grooves 605, and the key bar 603 will buckle the positioning groove 605. When it is necessary to adjust the angle of the cantilever beam support 6, first pull the short tube 602 out of the annular chamber 604, re-calibrate the position of the key bar 603 relative to the positioning groove 605, and re-lock it.

[0038] like Figure 8 As shown, the locking ring mechanism includes an annular groove 802, which is fixedly arranged at the end of the hollow tube 801, and four perforations are arranged on the outer side of the annular groove 802, and a steel needle 804 is arranged on the inner side of the perforations, and a steel ball is arranged on the outer end of the steel needle 804, and a curved hemisphere 805 is arranged on the inner end of the steel needle 804, and a return spring 806 is sleeved on the outer side of the steel needle 804, and one end of the return spring 806 is fixedly connected to the inner wall of the annular groove 802. The other end of the reset spring 806 is fixedly connected to the curved hemisphere 805. A disassembly ring 803 is provided at the end of the annular groove 802 facing away from the hollow tube 801. An expansion component is also provided on the outer side of the annular groove 802. The curved hemisphere 805 applies pressure to the plug 7 through the pressure of the reset spring 806. The four curved hemispheres 805 lock the plug 7 at the same time. When the steel needle 804 and the curved hemisphere 805 move toward the outside, the plug 7 is released, thereby achieving the effect of convenient disassembly.

[0039] like Figure 7 , 8 As shown, the expansion component includes a snap-fit ​​twist ring 9, a positioning chamber 901 is arranged on the inner side of the snap-fit ​​twist ring 9, four spring pieces 902 are arranged on the inner side of the positioning chamber 901, an expansion groove 903 is arranged in the middle of the spring piece 902, the expansion groove 903 is plugged into the steel needle 804, and the port of the expansion groove 903 is smaller than the diameter of the steel ball. When the snap-fit ​​twist ring 9 is rotated, the four spring pieces 902 on the inner side of the snap-fit ​​twist ring 9 will pull out the steel ball at the end of the steel needle 804, and the plug 7 can be detached from the hollow tube 801, thereby achieving the effect of convenient disassembly.

[0040] like Figure 7 , 8As shown, the end of the plug 7 is provided with a plug column, and a chamfered head 702 is provided on the end face of the plug column. A lubrication ring groove 701 is also provided in the middle of the plug column. The curved hemisphere 805 is inserted into the inner side of the lubrication ring groove 701. The curved hemisphere 805 passes over the plug 7 column and enters the lubrication ring groove 701. The plug 7 will be connected to the hollow tube 801. At the same time, the plug 7 and the conversion cross bar 5 can still rotate.

[0041] like Figure 8 As shown, the torque ring 8 is composed of two half rings, and organic oil is applied between the torque ring 8 and the annular groove 101. The torque ring 8 rotates around the annular groove 101. When the three columns 1 are erected, if the construction site is relatively large, the connection line of the columns 1 will approach a larger circle, and the connection line between the three columns 1 will approach a straight line. However, if the construction site is relatively small, the connection line between the columns 1 will be a circle with a smaller radius. The torque ring 8 and the hollow tube 801 can be turned to any angle, and even the three columns 1 can be arranged in a triangle, which can be adapted to any construction site. Compared with the protective wall of the prior art, the previous protective wall is more troublesome to erect in irregular sites.

[0042] Finally, the open-loop buckle 501, closed-loop buckle 502 and elastic clip 503 at the end of the conversion cross bar 5 can be converted at will. The barrier cloth 4 in the middle of the conversion cross bar 5 has four connection methods, and various types of barrier cloths 4 can be installed. Compared with the protective wall device in the prior art, the previous protective wall device and the barrier cloth 4 had only one installation method. According to the construction situation, if different types of 4 need to be built, it is also necessary to replace the connecting buckles on the frame accordingly. When installing the device, the divergent bracket 301 is attached to the ground, and then the chassis 3 is knocked down with a hammer. The divergent bracket 301 will be hammered into the soil. The divergent bracket 301 strengthens the grip. Compared with the installation method of the prior art, the previous protective wall also needed to dig a groove on the ground first, and In order to reinforce the protective wall, it is also necessary to add inclined legs to the protective wall, which makes the protective wall device occupy a larger area. There is no need to use inclined legs when the divergent bracket 301 is inserted into the soil. The wire mesh layer reinforces the strength of the barrier cloth 4 to prevent the barrier cloth 4 from being torn over a large area. When it is windy, the wire mesh layer also serves as a plastic film skeleton. When clothes need to be hung on the device, the hanger 201 and the top rod 204 are pulled out, and then the end of the top rod 204 is inserted into the resistance notch 202. The construction workers on site put the removed outer cantilever on the clothing hook 203. When the hanger 201 and the top rod 204 are put away, the magnet block inside the lying groove 2 attracts the hanger 201 and the top rod 204, and the internal space of the column 1 is also fully utilized. When the angle of the cantilever beam bracket 6 needs to be adjusted, first pull the short tube 602 out of the annular chamber 604, re-calibrate the position of the key strip 603 relative to the positioning groove 605 and re-lock it. The curved hemisphere 805 applies pressure to the plug 7 through the pressure of the reset spring 806. The four curved hemispheres 805 lock the plug 7 at the same time. When the steel needle 804 and the curved hemisphere 805 move outward, the plug 7 is released, thereby achieving the effect of convenient disassembly. The engaging twist ring 9 is rotated to engage. The four spring pieces 902 on the inner side of the torsion ring 9 will pull out the steel ball at the end of the steel needle 804, and the plug 7 can be separated from the hollow tube 801, achieving the effect of convenient disassembly. The curved hemisphere 805 passes over the plug 7 column and enters the lubrication ring groove 701, and the plug 7 is connected to the hollow tube 801. At the same time, the plug 7 and the conversion cross bar 5 can still rotate. If the construction site is relatively large, the connection line of the column 1 will approach a larger circle, and the connection line between the three columns 1 will approach a straight line. However, if the construction site is relatively small, the connection line between the columns 1 will be a circle with a smaller radius. The torsion ring 8 and the hollow tube 801 can be turned to any angle, and even the three columns 1 can be arranged in a triangle, which can be adapted to any construction site.Compared with the existing protective walls, the previous protective walls are more troublesome to erect in irregular sites.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
