Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically a foldable guardrail for municipal construction. Background Technology

[0002] Construction fencing is commonly used on ordinary roads, highways, and at intersections, toll stations, bridges, parking lots, stations, docks, dangerous areas, road construction sites, and temporary barriers at assembly points. It serves as a road divider, area enclosure for safety isolation, traffic diversion, and guidance. It is also used for maintaining order at celebratory events or sports and entertainment performances. Additionally, it can be used to protect and safeguard equipment and facilities in factories, workshops, warehouses, parking lots, commercial areas, and public places.

[0003] Currently, Chinese patent application number 202322355159.2 discloses a construction fence, including a fence body and support posts. The fence body has first connecting rods symmetrically fixedly connected to both sides, and connecting rings are fixedly connected to the outer sides of the first connecting rods. The support posts have fixed sleeves symmetrically fixedly fitted on their surfaces, and support frames are symmetrically fixedly connected to both sides of the fixed sleeves. Limiting blocks are fixedly installed on the surface of the support frames, and limiting plates are inserted into the surface of the support frames. A movable rod is fixedly connected to the bottom end of the limiting plate, and a connecting plate is fixedly connected to the bottom end of the movable rod. Although this invention facilitates the connection between the fence body and support posts through the engagement of the connecting rings and limiting blocks, and the limiting plates can limit the connection rings, thus improving the stability of the device, and the rotation of the threaded rod limits the limiting plates, facilitating quick disassembly of the fence body and support posts, greatly improving work efficiency, it has some drawbacks: 1. Although it can be disassembled, it only connects the fence body to the support post, and the connection structure is relatively complicated to operate. In particular, the fence body is quite long and cannot be disassembled and folded. It takes up a lot of space during transportation and is also difficult to move. 2. Due to the large size of the fence body, it is obviously impossible for one worker to complete the installation independently, which makes the installation difficult and reduces work efficiency. Therefore, this utility model provides a foldable guardrail for municipal construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable guardrail for municipal construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable guardrail for municipal construction, comprising a first post and a second post, wherein the second post is provided on the right side of the first post, and threaded posts are welded to the bottom ends of both the first post and the second post, wherein the threaded posts are threadedly connected to the mounting groove inside the upper end of the base. A connecting cylinder A is welded to the right end face of the first column. The connecting cylinder A has two sets, upper and lower, both of which are through structures. A detachable protective plate is installed inside the first column. A pin A corresponding to the connecting cylinder A is welded to the left side of the protective plate. The pin A is inserted into the connecting cylinder A and rotated. Connecting cylinders B are welded to both the upper and lower sides of the right end face of the protective plate. The protective plate has multiple sets with the same structure. Multiple protective plates are installed together by connecting pin A and connecting cylinder B. A pin B is welded to the left end face of the second column. The pin B is inserted into the connecting cylinder B welded to the right end face of the protective plate and rotated to connect.

[0006] As a preferred embodiment of this utility model, both the first column and the second column have hollow interiors, and both the top corners of the first column and the second column have rounded chamfered edges.

[0007] As a preferred embodiment of this utility model, there is a gap between adjacent protective plates, and the four corners of the protective plates are all arc-shaped chamfered structures.

[0008] As a preferred embodiment of this utility model, the protective plate has a through-type groove, and multiple through-type grooves are provided at equal intervals from top to bottom.

[0009] As a preferred embodiment of this utility model, the upper end of the base is cylindrical, the lower end is conical, and the interior of the bottom end of the base has an arc-shaped concave structure.

[0010] In a preferred embodiment of this utility model, the pin A and pin B have the same structure, the connecting cylinder A and connecting cylinder B have the same structure, and the pin A is longer than the connecting cylinder A.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, pins and connecting cylinders are welded to the inner ends of the two columns, and pins and connecting cylinders are also welded to both sides of the protective plate. The two connecting columns and the protective plate are connected by pins and connecting cylinders for installation and disassembly. This not only makes the operation convenient, but also allows workers to complete the work independently, thus improving work efficiency.

[0012] 2. The protective plate in this utility model is relatively small in size and has multiple assembleable protective plates. It can be disassembled and folded, which not only makes transportation more convenient but also makes handling easier, thus achieving the function of easy installation and disassembly.
