[0032] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0033] The following is combined with Figure 1-Figure 7 This embodiment is described in further detail.

[0034] See also Figures 1-4In this embodiment, a foldable safety fence for construction includes a fence unit and an installation unit for installing the fence unit. The fence unit includes two rotatably connected outer frames 100. A plurality of columns 101 are provided in the outer frame 100. Warning signs 110 are provided on the columns 101 through installation components. The installation components can be rotatably arranged on the columns 101. The installation components include a fixing part 410 for installing the warning sign 110 and a clamping part 420 for holding the fixing part 410 on the column 101. The opposite side walls of the outer frame 100 are rotatably connected through a rotating part; the installation unit includes a mounting column 120, and the outer wall of the mounting column 120 is connected to the corresponding side wall of the outer frame 100 through a connecting member.

[0035] In this embodiment, a bottom plate 121 is provided at the bottom end of the mounting post 120. The bottom plate 121 is mounted on the ground by expansion bolts. The opposite side walls of the two outer frames 100 are rotatably connected by a rotating member to achieve splicing of the outer frames 100. At the same time, the two outer frames 100 can be folded for transportation. The side walls of the two outer frames 100 that are away from each other are connected to the corresponding mounting posts 120 by connecting members. In this way, the enclosure unit is installed on the ground to form a fence.

[0036] The warning sign 110 can be installed on the enclosure unit through the installation component, so that the warning sign 110 can remind pedestrians, and the outer frame 100 and the column 101 can intercept pedestrians to prevent pedestrians from mistakenly entering the dangerous area;

[0037] Among them, the rotatable setting of the mounting assembly on the column 101 makes it possible that when the direction of the warning sign 110 needs to be adjusted, the warning sign 110 is first removed from the mounting assembly, and the clamping member 420 is used to release the clamping of the fixing member 410, so that the mounting assembly can be rotated around the column 101 to change the position of the fixing member 410, so that the warning sign 110 can be installed on the fixing member 410 so that its direction can be adjusted. Compared with the existing embodiment, the direction of the warning sign 110 can be adjusted by rotating the mounting assembly in this embodiment, which is simple and convenient to operate.

[0038] like Figure 2-7 As shown, in this embodiment, the outer wall of the column 101 is provided with an annular groove 200 along its circumference, and a first clamping groove 411 for the column 101 to be clamped is provided on one side surface of the fixing member 410, and a first convex ring 500 is provided in the first clamping groove 411 to be clamped into the annular groove 200, and a second clamping groove 601 is provided on one side surface of the clamping member 420 to match the first clamping groove 411, and a second convex ring 600 is provided in the second clamping groove 601 to be clamped into the annular groove 200, and the clamping member 420 is fixed to the fixing member 410 by a bolt 421 to realize the clamping of the two on the column 101.

[0039] In this embodiment, in order to achieve the installation of the warning sign 110 on the fixing member 410, a side wall of the fixing member 410 extends outward to form a mounting portion 400, and the warning sign 110 is fixed to the mounting portion 400 by screws;

[0040] When the direction of the warning sign 110 needs to be adjusted, the warning sign 110 is first removed from the mounting portion 400, and then the bolts 421 are loosened to release the clamping between the fixing member 410 and the clamping member 420. At this time, the mounting assembly is rotated along the column 101 to change the direction of the mounting portion 400. Then, the bolts 421 are tightened to make the fixing member 410 and the clamping member 420 clamped on the column 101 again. At this time, the warning sign 110 is reinstalled on the mounting portion 400, and the adjustment of the direction of the warning sign 110 is preferably completed. The operation is simple and convenient.

[0041] It should be noted that during the rotation of the fixing member 410 and the clamping member 420, the first convex ring 500 and the second convex ring 600 are always in the annular groove 200, thereby preventing the clamping member 420 and the fixing member 410 from sliding down on the column 101 due to gravity. That is, during this process, there is no need to support the fixing member 410 and the clamping member 420 by hand, which makes operation more convenient.

[0042] like Figure 5-6 As shown, in this embodiment, in order to facilitate the operator to rotate the installation component, an operating handle 422 is provided on the upper end surface of the clamping member 420.

[0043] In this embodiment, when rotating the installation assembly, the operator can grasp the operating handle 422 to drive the clamping member 420 to rotate the installation assembly around the column 101, which is more convenient for the operator to use.

[0044] like Figure 5-6 As shown, in order to improve the holding stability between the fixing member 410 and the clamping member 420, in this embodiment, rubber pads are provided at the end faces of the first convex ring 500 and the second convex ring 600 close to the annular groove 200. Through the provision of the rubber pads, when the bolt 421 clamps the fixing member 410 and the clamping member 420, the rubber pads can squeeze the annular groove 200, thereby making the installation component difficult to rotate, thereby improving its holding effect.

[0045] like Figure 4 As shown, in this embodiment, the rotating member includes a fixed block 300 provided on one side wall of the outer frame 100 and a rotating shaft 301 provided on the other side wall of the outer frame 100 , and the rotating shaft 301 can extend into the fixed block 300 on the adjacent outer frame 100 .

[0046] In this embodiment, the fixing block 300 is provided with connection holes along its height direction, and the rotation shaft 301 is set through the corresponding connection holes through the fixing block 300, thereby realizing the rotational connection between adjacent outer frames 100. When the adjacent outer frames 100 need to be folded, the outer frames 100 can be grasped at the end faces away from each other and rotated to fold the two outer frames 100;

[0047] Specifically, the lower end of the rotating shaft 301 passing through the connection hole is threadedly connected to a nut 302. The nut 302 is arranged so that the rotating shaft 301 will not fall out of the connection hole, thereby preferably achieving a rotational connection between adjacent outer frames 100.

[0048] In order to improve the connection stability between the outer frames 100, multiple rotating members can be provided.

[0049] like Figure 1 and 7 As shown, in this embodiment, the connecting member includes a first connecting block 102 provided at the ends of the outer frame 100 that are away from each other, and a second connecting block 122 that matches the first connecting block 102 is provided on the mounting column 120.

[0050] In this embodiment, when the mounting post 120 needs to be connected to the outer frame 100, the first connecting block 102 and the second connecting block 122 can be connected by a screw and a nut 302, so as to achieve the installation of the outer frame 100 on the mounting post 120;

[0051] In order to improve the stability of the outer frame 100 when installed on the installation column 120, a plurality of connecting members may be provided.

[0052] like Figure 1 As shown, in this embodiment, second connection blocks 122 are provided at multiple end surfaces of the mounting post 120 .

[0053] In this embodiment, by setting the second connecting block 122 on multiple end faces of the mounting column 120, the outer frame 100 can be connected to different end faces of the mounting column 120, thereby enabling the enclosure unit to be connected on all four sides of the mounting column 120, thereby improving the diversity of the connection between the mounting unit and the enclosure unit.

[0054] like Figure 7 As shown, in this embodiment, a cavity 700 is provided in the mounting column 120 , and sand and gravel for counterweight are poured into the cavity 700 .

[0055] In this embodiment, a detachable cover is provided at the upper end of the mounting column 120 by screws. When the mounting column 120 needs to be transported, the cover can be removed and the sand and gravel in the cavity 700 can be poured out to reduce the weight of the mounting column 120 for easy transportation; when the mounting column 120 needs to be placed on the ground, sand and gravel can be poured into the cavity 700 to enhance its wind resistance and prevent it from being blown down in windy weather.

[0056] Working principle: When the direction of the warning sign 110 needs to be adjusted, first remove the warning sign 110 from the mounting portion 400, then loosen the bolt 421 to disengage the second convex ring 600 and the first convex ring 500 from the state of being close to the annular groove 200, rotate the fixing member 410 and the clamping member 420 to change the direction of the mounting portion 400 on the column 101, and then tighten the bolt 421 to make the second convex ring 600 and the first convex ring 500 close to the annular groove 200. At this time, the fixing member 410 and the clamping member 420 are fixed on the column 101, and finally the warning sign 110 can be installed on the mounting portion 400.
