Description

Technical Field

[0001] This utility model relates to the field of edge protection railing technology, and in particular to a modular edge protection railing that can be quickly assembled. Background Technology

[0002] In the construction process, edge protection is one of the most important measures to ensure worker safety. Especially when working at heights, edge protection railings can effectively prevent people from falling and reduce accidents. Edge protection railings are mainly used in high-altitude work areas on construction sites, especially at edges or unfinished floors. As the construction industry's requirements for construction safety continue to increase, the technology of modular edge protection railings is also constantly improving. Therefore, modular, quick-assembly edge protection railings have emerged and become a common solution in modern construction.

[0003] A search revealed an existing patent (publication number: CN221502789U) disclosing an edge protection railing. This edge protection railing includes a positioning post, a connector fixedly mounted on the left surface of the positioning post, a telescopic railing hinged to the right end of the connector, a base fixedly connected to the bottom of the positioning post, and a protective device provided on the front surface of the positioning post. When gravel impacts the baffle, the baffle experiences an inward compressive force, causing the hollow sleeve to contract and the spring to deform. The spring's reaction force combines with the compressive force from the baffle, improving the baffle's buffering effect against the impact of gravel. During the compression process inside the baffle box, the distance between the baffle and the magnetic strip decreases, increasing the magnetic force generated by the magnetic strip. This magnetic force further combines the impact force of the baffle, preventing the railing from breaking or deforming due to excessive impact, thus further improving the baffle's protective efficacy.

[0004] However, in the actual use of the above solution, the positioning post and the telescopic railing are hinged together by a connector. The hinged structure of the connector may require more steps to disassemble. Especially after installation and use for a period of time, the connector may become more difficult to disassemble due to loosening or wear, increasing the difficulty of disassembly. At the same time, if the disassembly of the connector requires additional tools or technical support, it may make the disassembly process more cumbersome and time-consuming, thus affecting the overall construction progress.

[0005] Therefore, this utility model provides a modular, quick-assembly edge protection railing. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the existing art of hinged connecting structures may require more steps to disassemble, especially after a period of use after installation, when the connecting parts may become more difficult to disassemble due to loosening or wear. Therefore, this invention proposes a modular and quick-assembly edge protection railing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A modular, quick-assembly edge protection railing includes a fixed rod with corresponding installation compartments on both sides. A pad is fixedly connected to the inner wall of each installation compartment. A detachable connector is provided on the outer side of the fixed rod. The pad and connector are connected via a quick-release assembly. A horizontal rail is provided on the outer side of the connector. A uniformly distributed first hinge frame is fixedly connected to the outer wall of the horizontal rail. A limit rod is rotatably connected to the inner side of the first hinge frame. The limit rod at one outer end is connected to the bottom horizontal rail via a telescopic assembly.

[0009] As a preferred technical solution of this application, the quick-release assembly includes a limiting frame, which is fixedly connected to the outer wall of the pad. The limiting frame is rotatably connected to two opposing clamping arms on the side away from the pad. A connecting block is engaged with the inner side of the clamping arm. Opposite second lead screws are threadedly connected to the two sides inside the limiting frame. A handle is fixedly connected to the outer wall of the end of the second lead screw away from the connecting block. The end of the second lead screw near the connecting block is engaged with the clamping arm.

[0010] As a preferred technical solution of this application, the connector includes a second hinge frame, the side of the second hinge frame away from the pad block being fixedly connected to the crossbar, and the side of the second hinge frame away from the crossbar being fixedly connected to the connecting block.

[0011] As a preferred technical solution of this application, the telescopic component includes two first lead screws. One end of the first lead screw on the side away from the pad is rotatably connected to the outer wall of the crossbar, and one end of the first lead screw on the side closer to the pad is rotatably connected to the middle section of the limiting rod. Threaded sleeves are threadedly connected to the outer sides of the ends of the two first lead screws that are close to each other.

[0012] As a preferred technical solution of this application, a limiting ring is fixedly connected to the side of the limiting frame away from the pad block and sleeved on the outside of the spring. The end of the limiting ring away from the limiting frame is fixedly connected to the outer wall of the clamping arm, and the limiting ring is sleeved on the outside of the lead screw.

[0013] As a preferred technical solution of this application, a support foot is fixedly connected to the outer side of the bottom of the fixing rod.

[0014] Compared with the prior art, this utility model provides a modular and quick-assembly edge protection fence, which has the following advantages:

[0015] 1. This utility model discloses a modular, quick-assembly edge protection fence. Through quick-release components, the fixed posts, horizontal bars, and limiting posts can be rapidly disassembled, improving construction efficiency and safety. This system saves time, reduces labor intensity, and allows for flexible adjustment of the fence layout, reducing costs and material waste. The modular design facilitates storage and transportation and supports reuse, while also improving response speed in emergency situations. It is an efficient, economical, and environmentally friendly construction solution.

[0016] 2. The modular, quick-assembly edge protection fence described in this utility model uses the extension and retraction of the telescopic components to drive the limit bar and the horizontal bar to rotate in opposite directions. This allows the equipment to flexibly adjust the angles of the horizontal and vertical bars according to different construction environments and protection requirements, thereby better adapting to various terrains and structures and ensuring the protective effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Reference Figure 1-5 A modular, quick-assembly edge protection barrier includes a fixed rod 1. Corresponding installation compartments 46 are provided on both sides of the fixed rod 1. Pads 4 are fixedly connected to the inner walls of the installation compartments 46, securing the pads 4 through the installation compartments 46 on the inner side of the fixed rod 1. A detachable connector is provided on the outer side of the fixed rod 1. The pads 4 and the connector are connected via a quick-release assembly, allowing for quick disassembly of the pads 4 and the connector. A horizontal bar 2 is provided on the outer side of the connector. The outer wall of the horizontal bar 2 is fixedly connected to evenly distributed first hinge frames 21, supporting and fixing the first hinge frames 21. A limit rod 22 is rotatably connected to the inner side of the first hinge frame 21. The limit rod 22 and the horizontal bar 2 are connected via the first hinge frame 21. The limit rod 22 at one outer end is connected to the bottom horizontal bar 2 via a telescopic assembly.

[0027] The quick-release assembly includes a limiting frame 41, which is fixedly connected to the outer wall of a pad 4. The pad 4 supports and fixes the limiting frame 41. On the side of the limiting frame 41 away from the pad 4, two opposing clamping arms 42 are rotatably connected. The limiting frame 41 limits the clamping arms 42. A connecting block 31 is engaged on the inner side of each clamping arm 42, connecting the clamping arms 42 to the connecting block 31. Two opposing second lead screws 44 are threadedly connected to the inner sides of the limiting frame 41. The limiting frame 41 limits the second lead screws 44, and the second lead screws 44 rotate within the limiting frame 41, thereby utilizing the screws on the inner wall of the limiting frame 41... The second lead screw 44 moves, thereby supporting the clamping arm 42 and preventing it from rotating. A handle 45 is fixedly connected to the outer wall of the end of the second lead screw 44 away from the connecting block 31. The handle 45 is fixed by the second lead screw 44, and rotating the handle 45 drives the second lead screw 44 to rotate synchronously. The end of the second lead screw 44 near the connecting block 31 is engaged with the clamping arm 42, supporting and engaging the clamping arm 42. After the clamping arm 42 clamps the connecting block 31, it is limited and supported, thus forming a rigid connection between the clamping arm 42 and the connecting block 31.

[0028] The connector includes a second hinge frame 3. The side of the second hinge frame 3 away from the pad block 4 is fixedly connected to the horizontal bar 2, and the side of the second hinge frame 3 away from the horizontal bar 2 is fixedly connected to the connecting block 31. The connecting block 31 and the horizontal bar 2 are connected by the second hinge frame 3, so that the connecting block 31 and the horizontal bar 2 can rotate.

[0029] The telescopic assembly includes two first lead screws 23. One end of the first lead screw 23 on the side away from the pad 4 is rotatably connected to the outer wall of the horizontal bar 2, and the other end of the first lead screw 23 on the side closer to the pad 4 is rotatably connected to the middle section of the limiting rod 22. The outer sides of the two first lead screws 23 that are close to each other are threadedly connected to threaded sleeves 24. The threaded sleeves 24 limit the opposite ends of the first lead screws 23, and by rotating the threaded sleeves 24, the distance between the first lead screws 23 is tightened or pushed away, thereby controlling the opening and closing angle between the horizontal bar 2 and the limiting rod 22.

[0030] A limiting ring 47 is fixedly connected to the side of the limiting frame 41 away from the pad 4, which is sleeved on the outside of the spring 43. The end of the limiting ring 47 away from the limiting frame 41 is fixedly connected to the outer wall of the clamping arm 42, and the limiting ring 47 is sleeved on the outside of the second lead screw 44. The spring 43 is limited by the limiting rings 47 on both sides.

[0031] A support foot 11 is fixedly connected to the outer side of the bottom of the fixed rod 1, and the fixed rod 1 is supported and fixed by the support foot 11.

[0032] Specifically, when using this modular, quick-assembly edge protection barrier: First, move the equipment to the usage position, then fix one side support leg 11. Next, insert the corresponding connecting block 31 on the outer side of the second hinge frame 3 into the opening of the installation chamber 46. Then, the connecting block 31 moves inward into the installation chamber 46, which will squeeze the clamping arms 42 on both sides and push the clamping arms 42 to both sides simultaneously. After the connecting block 31 moves inward into the clamping arms 42, rotate the handles 45 on both sides to move the second lead screw 44 to one side of the clamping arm 42, finally engaging with the clamping arm. The outer wall of the clamping arm 42 contacts the clamping arm 42 and supports it to prevent the clamping arm 42 from rotating, thus completing the connection between the second hinge frame 3 and the fixed rod 1. Then, the threaded sleeve 24 is rotated to tighten or push the distance between the first screw 23, thereby controlling the opening angle between the horizontal bar 2 and the limiting rod 22. The angle between the limiting rod 22 and the horizontal bar 2 is adjusted so that the equipment can better fit the usage scenario. Then, the other side of the horizontal bar 2 is connected to the fixed rod 1, and then the support foot 11 at the bottom of the fixed rod 1 is fixed to complete the installation and use.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
