Description

Technical Field

[0001] This utility model relates to the field of safety railing technology, specifically to a quick-assembly and disassembly safety railing. Background Technology

[0002] Before construction begins, to ensure safety, protective fences are typically installed around the construction site to isolate it. Existing protective fences usually consist of two posts and a barrier. Both the posts and the barrier have connecting plates with through holes. During installation, the posts are first fixed to the ground, and then the barrier is installed between the two posts using bolts connecting the posts to the connecting plates on the barrier.

[0003] In practice, after installing two posts on the ground, if the ground is uneven, the connecting plates on the two posts will not be parallel or at the same height, making it impossible to bolt the connecting plates on the posts to the connecting plates on the baffle. If the distance between the two posts is greater than or less than the required distance, the baffle cannot be installed on the posts. Therefore, when installing the posts, it is necessary not only to control the distance between the two posts precisely, but also to ensure that the connecting plates on the two posts are parallel, which brings various restrictions to the installation of the guardrail and slows down the disassembly and assembly speed.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to design a guardrail that allows for quick installation of a baffle on a column even when the columns are at different heights and the connecting pieces are not parallel, thereby addressing the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and disassembly safety railing, comprising two posts and a baffle between the two posts, wherein the baffle is configured as a retractable barrier, a vertical shaft is installed on each of the two posts, a first connecting block is rotatably mounted on the vertical shaft around the central axis, a second connecting block is rotatably mounted on the end of the first connecting block, the second connecting block forms an angle with the horizontal plane when rotating on the first connecting block, the ends of the two second connecting blocks are slidably connected to the ends of the barrier, and threaded fasteners are detachably mounted on the ends of the second connecting blocks and the barrier.

[0007] The angle between the stop bar and the horizontal plane is changed by the second connecting block, and the two columns and the stop bar are aligned on the same straight line by the first connecting block. With the telescopic stop bar, the two columns can be disassembled and assembled even if they are not at the same height and plane on the ground.

[0008] Preferably, the baffle bar includes a plurality of hollow rods with successively smaller cross-sectional areas. A baffle is fixedly installed at the end of the hollow rod. When the hollow rod is slidably connected within an adjacent hollow rod with a larger cross-sectional area, the baffle prevents it from completely sliding out of the hollow rod with the larger cross-sectional area.

[0009] Preferably, the ends of the hollow rods with the largest and smallest cross-sectional areas in the stop bar are each provided with a first through hole. A second connecting block on one column is inserted into the hollow rod with the largest cross-sectional area in the stop bar, and the hollow rod with the smallest cross-sectional area in the stop bar is inserted into the second connecting block on another column. Both second connecting blocks are provided with second through holes. The central axes of the first through holes and the second through holes coincide. The threaded fastener is installed in the first through holes and the second through holes.

[0010] Preferably, the threaded fastener includes a long bolt passing through the first through hole and the second through hole, and a nut threaded to the end of the long bolt.

[0011] Preferably, the column includes a base connected to the ground, a central shaft fixedly installed on the base, a top cap fixedly installed at the top of the central shaft, and a connector rotatably installed on the central shaft, wherein the vertical shaft passes through the connector and is rotatably connected to the connector.

[0012] Preferably, the number of the baffles is set to two or more, with the hollow rod with the largest cross-sectional area in one baffle located directly above the hollow rod with the smallest cross-sectional area.

[0013] Preferably, the number of the connectors is set to two, and when the two connectors are rotatably connected on the central axis, they are not on the same horizontal plane.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. Through the cooperation between the second connecting block and the telescopic stop strip, the stop strip can connect the two columns even if their horizontal heights are inconsistent when the columns are installed on undulating ground. This solves the limitation of the existing technology that requires the two columns to be kept parallel for installation. Installation can be carried out quickly without ground treatment or the selection of a level ground.

[0016] 2. Through the cooperation between the first connecting block and the retractable stop bar, the orientation of the first connecting block on the column, which was not originally parallel, can be adjusted. Unlike the existing technology, it is not necessary to keep the two connecting pieces parallel when installing the column. Instead, it can be adjusted later, thereby speeding up the installation of the column.

[0017] 3. By setting the guardrail to a telescopic style, it can not only be quickly installed with the first and second connecting blocks, but also the distance between the two posts can be adjusted at any time. Simply extend or shorten the guardrail and move the posts to improve the speed of adjusting the guardrail length according to road conditions.

[0018] 4. The structure of this utility model is relatively simple, easy to operate, and easy to assemble and disassemble. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model provides, for example Figure 1-4The safety railing shown includes two posts 1 and a baffle between the two posts 1. The baffle is configured as two or more retractable baffles 2. Each baffle 2 includes multiple hollow rods 2a with progressively smaller cross-sectional areas. A baffle plate 2c is fixedly installed at the end of each hollow rod 2a. When the hollow rod 2a slides within an adjacent hollow rod 2a with a larger cross-sectional area, the baffle plate 2c prevents it from sliding completely out of the hollow rod 2a with a larger cross-sectional area. The ends of the hollow rods 2a with the largest and smallest cross-sectional areas in the baffle 2 are each provided with a first through hole 2d. Each post 1 includes a base 1a connected to the ground, a central shaft 1b fixedly installed on the base 1a, a top cap 1c fixedly installed at the top of the central shaft 1b, and two connecting pieces 1d rotatably installed on the central shaft 1b. The two connecting pieces 1d rotate on the central shaft 1b. When connected, they are not on the same horizontal plane. A vertical shaft 3 is rotatably installed on the connector 1d. A first connecting block 4 is rotatably installed on the vertical shaft 3 around the central axis. A second connecting block 5 is rotatably installed at the end of the first connecting block 4. When the second connecting block 5 rotates on the first connecting block 4, it forms an angle with the horizontal plane. The second connecting block 5 on one column 1 is inserted into the hollow rod 2a with the largest cross-sectional area in the stop bar 2. The hollow rod 2a with the smallest cross-sectional area in the stop bar 2 is inserted into the second connecting block 5 on the other column 1. A second through hole 7 is opened in both second connecting blocks 5. The central axis of the first through hole 2d coincides with that of the second through hole 7. A long bolt 6a is slidably connected in the first through hole 2d and the second through hole 7. A nut 6b is threadedly connected to the end of the long bolt 6a. The nut 6b and the long bolt 6a together form a threaded fastener 6.

[0029] First, the workers installed two posts 1 on the road surface using base 1a according to the required length of the interception and isolation. Then, one end of the baffle 2 was connected to one of the second connecting blocks 5, so that its first through hole 2d coincided with the second through hole 7 on the second connecting block 5. A long bolt 6a was then inserted and tightened with a nut 6b to complete the connection between the baffle 2 and one of the posts 1. Then, the workers rotated the connector 1d and the first connecting block 4 on the other post 1 so that the first connecting block 4 faced the post 1 that had been installed. Then, the workers rotated the baffle 2 that had been installed on the post 1 and stretched the baffle 2 so that the end of the baffle 2 was aligned with the unconnected post 1. At this time, the two posts 1 and the baffle 2 were on the same plane.

[0030] When the bottom surface is uneven, causing the two columns 1 to be at different horizontal heights, the workers need to move the stop bar 2 up and down so that the stop bar 2 forms an angle with the horizontal plane, so that the stop bar 2 is aligned with the second connecting block 5 that has not been installed. Then, the end of the stop bar 2 is slidably connected to the end of the second connecting block 5. Finally, the long bolt 6a is inserted and the nut 6b is tightened to complete the installation of the stop bar 2 and the two columns 1.

[0031] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
