Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 5 The present invention provides a foldable warning fence, including a plurality of fence units connected together, each of the fence units including a column assembly 1 and an isolation net assembly 2, the isolation net assembly 2 is detachably connected to the column assembly 1, and two adjacent isolation net assemblies 2 share one column assembly 1 at their ends close to each other.

[0026] The column assembly 1 is used as the main support and positioning structure of the foldable warning fence, and the isolation net assembly 2 is mainly used for enclosure. When in use, the length of the foldable fence is determined by the number of the fence monomers. The enclosure range can be adjusted by adjusting the number of the column assembly 1 and the isolation net assembly 2.

[0027] The foldable warning fence of the present invention configures the fence unit into a detachably connected column assembly 1 and an isolation net assembly 2, so that the fence unit is a detachable combination structure, which is convenient for transportation after disassembly of the fence unit, convenient for handling, and easy for operation, thereby reducing the volume and weight of the transported unit and reducing the labor intensity of workers.

[0028] The foldable warning fence of the present invention further includes an infrared alarm 4 for warning to prevent unauthorized personnel from breaking in. The infrared alarm 4 is quickly inserted at the top of the column assembly 1 through a quick-insert structure commonly used by those skilled in the art to warn people near the fence. The structure of the infrared alarm 4 is a commonly used structure in the art and will not be described in detail here.

[0029] Specifically, the isolation net assembly 2 includes a net body 21. A net connector 22 is provided at a position of the net body 21 close to the column assembly 1, and the edge of the net connector 22 is slidably connected to the side surface of the column assembly 1. The net body 21 is a wire mesh or a nylon mesh. The net connector 22 is fixedly connected to the net body 21 through a fifth rivet 23.

[0030] Among them, the column assembly 1 includes a column 12, and the isolation net assembly 2 is connected to two opposite side surfaces of the column 12. The height of the column is greater than the height of the net body 21 to facilitate the reliable installation of the net body 21.

[0031] To ensure the use stability of the column 12 and thus improve the use stability of the fence, a column support assembly is connected to the side surface of the column 12 that is not connected to the isolation net assembly 2. The column support assembly includes a leg 14 and a leg link 15. Both the leg 14 and the leg link 15 are plate-shaped rods. One end of the column 12 is rotatably connected to one end of the leg 14 through a first rivet 13, and the other end of the leg 14 is rotatably connected to the leg link 15 through a second rivet 16. The other end of the leg link 15 is hooked or clamped on the side surface of the column 12 for connecting the leg 14. By hooking or clamping one end of the leg link 15 on the column 12, the deformation of the rod structure formed by the leg 14 and the leg link 15 is avoided, and the stability of the support structure is improved. At the same time, when one end of the hooked or clamped leg link 15 is removed from the column 12, the leg 14 and the leg link 15 can be folded together and placed close to the side surface of the column body of the column 12, reducing the volume of the overall structure and facilitating transportation and handling. In other embodiments, the first rivet 13 and the second rivet 16 can also be replaced with structures such as a rotating shaft or a screw, which are selected by those skilled in the art according to the actual manufacturing process and will not be limited here.

[0032] In a specific embodiment, four net connectors 22 are provided, the net body 21 is a rectangular structure net, and the four net connectors 22 are fixedly connected to the four corners of the net body 21. A track groove 122 is provided on the side surface of the column 12 of the column assembly 1 where the net connector 22 is connected, and a slider is provided on the edge of the net connector 22 for connecting to the track groove 122. The cross-sectional shape of the slider corresponds to the cross-sectional shape of the track groove 122, and the slider is slidably connected in the track groove 122. Specifically, the track groove 122 is a T-shaped groove or a dovetail groove. It can be understood that for convenient installation, the track groove 122 is provided in a through manner along the height direction of the column 12.

[0033] To limit the position where the net body 21 is connected to the column 12 and prevent it from falling out of the bottom end of the track groove 122 on the column 12, a limiting block 19 for limiting is provided at the lower end of the track groove 122. The limiting block 19 is connected to the bottom surface of the track groove 122 through the fourth rivet 110. By providing the limiting block 19, the height of the bottommost edge of the net body 21 is restricted. By setting the limiting blocks 19 on each column 12 at the same height position, the structural consistency of the fence unit is improved.

[0034] In a specific embodiment, a column cap 11 is connected to the top end of the column 12 to prevent the top surface edge of the column 12 from scratching the user.

[0035] To facilitate the storage of the folded legs 14 and leg linkages 15, a column storage groove 121 is provided on the side surface of the column 12 for connecting the legs 14. The widths of the legs 14 and leg linkages 15 can be the same or different. It can be understood that the column storage groove 121 runs through the column 12 in the height direction, and the width dimension of the column storage groove 121 is greater than the width of the wider one of the legs 14 and leg linkages 15. The widths of the legs 14 and leg linkages 15 refer to the dimensions in the width direction of the column storage groove 121. Baffle edges are provided on both sides of the column storage groove 121, and the baffle edges are arranged in the height direction of the column 12. Both ends of the first rivet 13 are fixedly connected to the two baffle edges respectively.

[0036] Among them, to ensure the position stability of the column 12, two column support components are provided on each column 12, and the two column support components are arranged on two opposite side surfaces of the column 12, that is, on the side surface without the track groove 122.

[0037] To facilitate the fixed limitation of the fence, a ground nail 3 is provided at the end of the leg linkage 15 far from the column 12. Among them, the ground nail 3 is inserted into the positioning through hole on the leg linkage 15 for positioning the column 12. The tail end of the ground nail 3 is used to connect to the ground, and the head end dimension is larger than the diameter of the positioning through hole, so as to prevent the leg linkage 15 from slipping off the ground nail 3. As Figure 2 shown, the head end of the ground nail 3 is a bent end. In this way, it is not only convenient to insert into the bottom surface but also convenient to pull out, improving the convenience of use. In other embodiments, the head end of the ground nail 3 can also be a round end or a hexagonal end, which is not limited here.

[0038] To facilitate the connection between the outrigger link 15 and the column 12, a hanging structure 17 is provided on the column 12. Specifically, the hanging structure 17 is a hanging shaft or a hanging ring. A first hook is provided at one end of the outrigger link 15 connected to the column 12, and the hook is hung on the hanging shaft or the hanging ring. In other embodiments, a hanging hole is provided at one end of the outrigger link 15 connected to the column 12, the hanging structure 17 is a second hook, and the hanging hole is hung on the second hook. The first hanging structure 17 is connected to the column 12 by a third rivet 18. Alternatively, a card slot is provided on the column 12, and a card block is provided at one end of the outrigger link 15 connected to the column 12, and the card block is clamped in the card slot.

[0039] When the foldable warning fence of the present invention is installed, after the two sets of column assemblies 1 are unfolded and placed properly, the net connectors 22 on both sides of the isolation net assembly 2 are inserted along the track groove 122 on the column 12 and stopped at the limit block 19. The outriggers 14 and the outrigger links 15 are screwed out from the column storage groove 121, the end of the outrigger link 15 is connected to the hanging structure 17, the fence is fixed with ground nails 3, and then the infrared alarm 4 is inserted at the top of each column assembly 1 to form a warning fence. Repeat the above operations to make the fence infinitely extendable. When disassembling, the isolation net assembly 2 is removed from the column 12, the ground nails 3 are pulled out, then the outrigger link 15 is removed from the hanging structure 17, the outrigger link 15 is folded upward to coincide with the outrigger 14, and then the two are turned upward together and placed in the column storage groove 121, and the column assembly 1 will fold.

[0040] For the foldable warning fence provided by the present invention, the column assembly 1 is a foldable structure, which saves storage space. The connection between the outrigger link 15 and the column 12 adopts a clamping or hanging structure, making the installation and disassembly more convenient and fast. The foldable warning fence provided by the present invention is composed of column assemblies 1, isolation net assemblies 2 and infrared alarms 4 as sub-units of the fence monomers, and can be infinitely extended according to needs to meet the requirements of different occasions.
