The guardrail assembly 604 includes a plurality of guardrail posts 604a arranged in an array and equidistant control members 604b connected between adjacent guardrail posts 604a, each of the equidistant control members 604b being of equal length. A plurality of single guardrail legs 604a can be distributed on the periphery of the bottom frame 601 and the top frame 602 in an annular array, and together form an accommodating space.

The equidistant control members 604b are preferably elastic cords that ensure that the annular array of individual guardrail members 604a are equally spaced. The guardrail single branches 604a at the head end and the tail end are respectively connected with a connecting piece 604c, and the connecting pieces 604c are used for the end-to-end connection of the guardrail single branches 604a in the annular array. The connecting member 604c can be a flexible rope, so that the single guardrail legs 604a at the head and tail ends can be knotted and connected through the flexible rope, and in addition, the connecting member 604c can also be a detachable connecting mechanism such as a buckle.

The single guardrail leg 604a comprises a first rod section 604a-1 corresponding to the space between the bottom frame 601 and the top frame 602 and a second rod section 604a-2 corresponding to the space between the top frame 602 and the suspension rod 603, and a bend is formed between the first rod section 604a-1 and the second rod section 604 a-2.

the outer end of the first rod section 604a-1 is provided with a first slip ring 604a-3 which can be sleeved on the first semicircular sliding rod 601a and can slide relatively; a second sliding ring 604a-4 which can be sleeved on the second semicircular sliding rod 602a and can slide relatively is arranged between the first rod section 604a-1 and the second rod section 604 a-2; the outer end of the second pole segment 604a-2 is provided with a hook 604 a-5.

The first slip ring 604a-3 and the second slip ring 604a-4 are both provided with notches to ensure that the first slip ring 604a-3 is not hindered by the stroke of the first splicing bar 601b when sliding on the closed ring formed by connecting the two first semicircular slide bars 601a, and also ensure that the second slip ring 604a-4 is not hindered by the stroke of the second splicing bar 602b when sliding on the closed ring formed by connecting the two second semicircular slide bars 602 a.

The outer side wall of the suspension rod 603 is provided with a convex annular boss 603c, the upper surface of the annular boss 603c is provided with an annular groove 603c-1 matched with the hook body 604a-5, and the hook body 604a-5 at the upper end of each guardrail single branch 604a can be embedded into the annular groove 603 c-1.

An extrusion part 603d is connected to the suspension rod 603, a through screw hole is formed in the extrusion part 603d, an external thread matched with the screw hole of the extrusion part 603d is arranged on the outer side wall of the suspension rod 603, and the external thread is located on a section between the annular boss 603c and the hanging ring 603 b. The hook bodies 604a-5 embedded in the annular groove 603c-1 can be uniformly extruded by rotating the extruding piece 603d, so that the hook bodies cannot fall off and loosen. Extrusion 603d is preferably of a nut configuration to facilitate torque control.

In summary, the assembly process of the accommodating unit 600 is as follows:

firstly, one end of any first semicircular slide bar 601a sequentially passes through the first sliding rings 604a-3 of the single guardrail branches 604a, one end of any second semicircular slide bar 602a sequentially passes through the second sliding rings 604a-4 of the single guardrail branches 604a, and the limit groove 603a of the suspension rod 603 is embedded into the semicircular hole 602 c-1;

Secondly, the first splicing body and the second splicing body are connected through a first splicing strip 601b, and the third splicing body are connected through a second splicing strip 602 b;

Thirdly, placing articles on the bottom frame 601, scattering the single guardrail branches 604a (the uniform distribution is realized by the equidistant control piece 604 b), and connecting the single guardrail branches end to end by the connecting piece 604c to form a circle of protective fence;

Fourthly, the extrusion piece 603d is rotated to uniformly extrude the hook bodies 604a-5, so that the integral stability is realized.

Since the disassembly process is the reverse process, it is not described herein.

It is important to note that the construction and arrangement of the present application as shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters (e.g., temperatures, pressures, etc.), mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in this application. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. Accordingly, all such modifications are intended to be included within the scope of this invention. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. In the claims, any means-plus-function clause is intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures. Other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present inventions. Therefore, the present invention is not limited to a particular embodiment, but extends to various modifications that nevertheless fall within the scope of the appended claims.

Moreover, in an effort to provide a concise description of the exemplary embodiments, all features of an actual implementation may not be described (i.e., those unrelated to the presently contemplated best mode of carrying out the invention, or those unrelated to enabling the invention).

It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, without undue experimentation.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
