[0028] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0029] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present disclosure. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In the related art, one-piece stainless steel anti-theft nets are generally installed to prevent theft or solve the problem of falling objects. However, the color of the one-piece stainless steel anti-theft nets usually does not match the decoration style. If the one-piece anti-theft nets are to be presented in different colors indoors and outdoors to match the decoration style, the indoor and outdoor sides of the one-piece anti-theft nets need to be painted separately, which is inconvenient to manufacture and has a single effect.

[0031] Based on this, Figure 1 As shown, an exemplary embodiment of the present disclosure provides a door and window guardrail 100, comprising: a frame 10 and a plurality of guardrail units 20. The frame 10 comprises a first frame profile 11 and a second frame profile 12 opposite to each other; the plurality of guardrail units 20 are arranged between the first frame profile 11 and the second frame profile 12, and are arranged at intervals along a first direction, and the first direction is parallel to the extension direction of the first frame profile 11. Each guardrail unit 20 comprises a first guardrail profile 21 and a second guardrail profile 22 opposite to each other, the first guardrail profile 21 is arranged on the first side of the door and window guardrail 100, and the second guardrail profile 22 is arranged on the second side of the door and window guardrail 100, and the first guardrail profile 21 and the second guardrail profile 22 have different colors; the two ends of each guardrail unit 20 are detachably connected to the first frame profile 11 and the second frame profile 12, respectively.

For example, the first guardrail profile 21 and the second guardrail profile 22 are respectively arranged on the indoor side and the outdoor side of the door and window guardrail 100, so that the first guardrail profile 21 on the indoor side of the door and window guardrail 100 can have a color that matches the interior decoration style, and the second guardrail profile 22 on the outdoor side of the door and window guardrail 100 can have a color that matches the wall style of the outdoor building. In addition, due to the split design of the guardrail unit 20, the first guardrail profile 21 and the second guardrail profile 22 of different colors can be mass-produced so that the appearance colors of the first guardrail profile 21 and the second guardrail profile 22 respectively meet the appearance style requirements of the first side and the second side of the door and window guardrail 100. The first guardrail profile 21 and the second guardrail profile 22 are assembled into the guardrail unit 20 and are detachably connected to the first frame profile 11 and the second frame profile 12. In this way, the door and window guardrail 100 can be presented in different colors on the first side and the second side through a simple installation method to match the indoor and outdoor decoration styles. The production and assembly are simple, which improves the production efficiency of the door and window guardrail.

[0033] In addition, due to the split design of the door and window guardrail 100, the first guardrail profile 21 and the second guardrail profile 22 can be flexibly replaced and recycled. For example, when the indoor decoration style or the outdoor building wall style changes, only the first guardrail profile 21 or the second guardrail profile 22 can be replaced without replacing the door and window guardrail 100 as a whole, and the disassembled first guardrail profile 21 or the second guardrail profile 22 can be further recycled, which can save resources and reduce costs.
