Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a folding edge guardrail. Background Technology

[0002] With the rapid development of the national market economy and the acceleration of urbanization, land resources are becoming increasingly scarce, and the number of high-rise and super high-rise buildings in cities is increasing. During the construction process, safety protection is needed around the construction site.

[0003] For example, CN210439780U discloses a foldable construction guardrail that adopts a movable installation structure, making it convenient for users to store the construction guardrail. This construction guardrail has the advantage of being foldable, and its structure is simple, safe, reliable, low-cost, and easy to maintain. It is convenient for users to store and improves the practicality of construction guardrails. It solves the problem that most existing guardrails cannot be folded and are inconvenient for users to store because they do not adopt a movable installation structure.

[0004] The standard dimensions of edge protection barriers are fixed and cannot adapt well to different boundary lengths, often resulting in "redundancy" or "insufficiency" in edge protection length. On the other hand, after prolonged use, the connections between barrier components can become loose, making folding and storage unstable, inconvenient for transportation and storage, and leading to low work efficiency.

[0005] Therefore, a foldable edge protection barrier is needed to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a foldable edge protection railing, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0008] A folding edge protection fence includes a left post and a right post. A protective fence body is integrally formed on the right post. A pivot hinge, allowing adjacent protective fence bodies to rotate, is fixedly connected to both the left and right posts. A telescopic guardrail is movably inserted into the upper end of each protective fence body, with the other end of the telescopic guardrail fixedly connected to the left post. A kick plate is installed at the lower end of the protective fence body, with a telescopic kick plate movably inserted inside. The other end of the telescopic kick plate is fixedly connected to the left post. A folding guardrail is slidably connected to the side walls of the protective fence body and the left post. A sturdy structure is installed at the top of the protective fence body to limit and fix adjacent protective fence bodies after folding.

[0009] Furthermore, the folding guardrail comprises two folding rails connected movably in the middle by a pivot. Limiting sliders are provided at both ends of the folding rails, and the sliders are slidably connected to the guardrail body and the left post through a sliding groove.

[0010] Furthermore, both the telescopic guardrail and the telescopic kick plate have limit holes, and the guardrail body has through holes of the same size as the limit holes. The telescopic guardrail and the telescopic kick plate are connected to the guardrail body by means of fixing pins passing through the through holes and the limit holes. The upper and lower ends of the guardrail body have storage cavities for storing the telescopic guardrail and the telescopic kick plate.

[0011] Furthermore, the pivot hinge includes pivot hinge one and pivot hinge two, which allow two adjacent guardrails to rotate to adapt to the curved edge protection.

[0012] Furthermore, the stabilizing structure includes a rotating plate installed in the mounting groove on the top of the guardrail body via a rotating shaft seat, a limiting plate installed at the front end of the rotating plate, and a limiting groove opened on the other side of the top of the guardrail body relative to the stabilizing structure, which is limited and fixed to the limiting plate by a limiting screw through a limiting screw hole.

[0013] This utility model has the following features and beneficial effects:

[0014] 1. This utility model adjusts the telescopic guardrail and telescopic kick plate in the storage cavity of the guardrail body to extend or fold the folding guardrail, thereby changing the size of the edge guardrail to better adapt to different boundary lengths and form an adjustable edge protection length.

[0015] 2. The interlocking guardrails are folded from the shaft-type hinges. After the limiting plate on the sturdy structure rotates, it is fixed with the limiting groove, making the folding and storage of the guardrails more stable, facilitating transportation and storage, improving work efficiency. Several folded guardrails can be transported together to other locations that require edge protection and then unfolded for use. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0033] like Figure 1-5As shown, a folding edge protection fence includes a left post 2 and a right post 1. A guardrail body 3 is integrally formed on the right post 1, and a railing 34 is installed on the guardrail body 3. A pivot-type hinge, allowing the adjacent guardrail bodies 3 to rotate, is fixedly connected to the left post 2 and the right post 1 respectively. A telescopic guardrail 4 is movably inserted into the upper end of the guardrail body 3, and the other end of the telescopic guardrail 4 is fixedly connected to the left post 2. A kick plate 6 is installed at the lower end of the guardrail body 3, and a telescopic kick plate 61 is movably inserted inside the kick plate 61. The other end of the telescopic kick plate 61 is fixedly connected to the left post 2, and the upper limit of the side wall of the guardrail body 3 and the left post 2 is slidably connected to the folding guardrail 5; by adjusting the telescopic guardrail and the telescopic kick plate in the storage cavity of the guardrail body, the folding guardrail is simultaneously extended or folded, thereby changing the size of the edge guardrail so as to better adapt to different boundary lengths; a stable structure 7 is installed on the top of the guardrail body 3 to limit and fix two adjacent guardrail bodies 3 after folding; it is convenient for stable storage.

[0034] To better adapt to different boundary lengths, the folding guardrail 5 consists of two folding rails connected movably in the middle by a pivot. Limiting sliders 51 are provided at both ends of the folding rails, and these sliders 51 are slidably connected to the guardrail body 3 and the left post 2 via a sliding groove 32. Limiting holes 41 are provided on both the telescopic guardrail 4 and the telescopic kick plate 61. A through hole 33 of the same size as the limiting hole 41 is provided on the guardrail body 3. The telescopic guardrail 4 and the telescopic kick plate 61 are connected to the guardrail body 3 by a fixing pin passing through the through hole 33 and the limiting hole 41. Storage cavities 31 are provided at the upper and lower ends of the guardrail body 3 for storing the telescopic guardrail 4 and the telescopic kick plate 61. By adjusting the extension length of the telescopic guardrail 4 and the telescopic kick plate 61 into the storage cavity 31 of the guardrail body 3, the folding guardrail 5 can be extended or folded, thereby changing the size of the edge protection guardrail to better adapt to different boundary lengths and form an adjustable edge protection length.

[0035] The hinge includes hinge 11 and hinge 21. During use, the two hinges can be fixed by interlocking, so that the two adjacent guardrails 3 can rotate to adapt to the curved edge protection.

[0036] When not in use, insert the telescopic guardrail 4 and telescopic kick plate 61 on each guardrail body 3 into the storage cavity 31 inside the guardrail body 3, and fold up the folding guardrail 5. Use the fixing pin to pass through the through hole 33 and the limiting hole 41 to limit and fix it to the guardrail body 3. Fold the guardrail bodies 3 that are inserted into each other from the shaft-type hinge. The folding method is similar to that of a folding fan. Transport the folded guardrail bodies 3 together to other locations that need edge protection and unfold them for use.

[0037] like Figure 4-5As shown, in order to ensure that the two adjacent guardrails are stably stored after being folded, the stabilizing structure 7 includes a rotating plate 72 installed in the mounting groove on the top of the guardrail 3 via a rotating shaft seat 71. A limiting plate 73 is installed at the front end of the rotating plate 72. A limiting groove 35 is opened on the top of the guardrail 3 on the other side relative to the stabilizing structure 7, which is limited and fixed to the limiting plate 73 by a limiting screw through a limiting screw hole 74. After the guardrails 3 that are inserted into each other are folded from the shaft-inserted hinge, the limiting plate 73 on the stabilizing structure 7 is rotated via the rotating plate 72 through the rotating shaft seat 71, so that the limiting plate 73 is limited to the limiting groove 35, and then the limiting screw passes through the limiting screw hole 74 to limit and fix it.

[0038] like Figure 1 and 3 As shown, in order to facilitate the transfer of the guardrail body, casters 10 are installed at the bottom of the left post 2 and the right post 1. The casters 10 are brake casters with a braking structure, which makes the device stable; and they are fixed by a fixed base and a fixed rod; the casters 10 facilitate the transfer of the guardrail body 3 to other locations that require edge protection for deployment.

[0039] When this utility model is used, it can be fixed by inserting two shaft-type hinges, so that the two adjacent guardrail bodies 3 can rotate to adapt to the curved edge protection. At the same time, by adjusting the extension length of the telescopic guardrail 4 and the telescopic kick plate 61 in the storage cavity 31 of the guardrail body 3, the folding guardrail 5 can be extended or folded. The fixing pin passes through the through hole 33 and the limiting hole 41 to limit and fix it, thereby changing the size of the edge protection guardrail so as to adapt well to different boundary lengths and form an adjustable edge protection length.

[0040] When not in use, insert the telescopic guardrail 4 and telescopic kick plate 61 on each guardrail body 3 into the storage cavity 31 inside the guardrail body 3. At the same time, fold up the folding guardrail 5. Use the fixing pin to pass through the through hole 33 and the limiting hole 41 to limit and fix it to the guardrail body 3. Fold the guardrail bodies 3 that are inserted into each other from the shaft-type hinge. The folding method is similar to that of a folding fan. Rotate the limiting plate 73 on the stabilizing structure 7 through the rotating plate 72 and the rotating shaft seat 71 to limit the limiting plate 73 and the limiting groove 35. Then use the limiting screw to pass through the limiting screw hole 74 to limit and fix it. This makes the folding and storage more stable, facilitates transportation and storage, and improves work efficiency. The folded guardrail bodies 3 can be transported together to other locations that need edge protection and then unfolded for use.
