[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0033] The embodiments of this utility model will be described below based on its overall structure.
[0034] First embodiment:
[0035] Please see Figures 1-5 This embodiment provides an anti-climbing guardrail, including guardrail posts 1, guardrail frames 2, flanges 3, and perforated plates 5. The guardrail posts 1 have an outer wall with a shaft 4, and a circular tube 41 is installed on the outer wall of the shaft 4. The shaft 4 and the circular tube 41 are connected by a circular bearing, and the length of the circular tube 41 is equal to the width of the guardrail frames 2, allowing the circular tube 41 to rotate flexibly around the shaft 4. Once a climber touches the circular tube 41, it will rotate due to the force, increasing the difficulty of climbing and effectively preventing climbing behavior. The guardrail frames 2 have a perforated plate 5 installed on their outer wall, and the outer wall of the perforated plate 5 is tightly attached to the outer walls of the guardrail posts 1 and the guardrail frames 2. The perforated plate 5 has numerous holes evenly distributed on it, which can meet basic ventilation needs and effectively reduce gaps and openings for climbing, enhancing the overall anti-climbing performance of the guardrail.
[0036] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The shaft 4 and the round tube 41 are connected by a round bearing, and the length of the round tube 41 is equal to the width of the guardrail frame 2. This helps to maintain the flexible rotation of the round tube 41. Once a climber touches the round tube 41, the round tube 41 will rotate due to the force. The part that the climber originally planned to grab or step on will instantly lose stable support, making it difficult for the hands and feet to find a point of leverage. This interferes with the continuity of the climber's climbing action, making it difficult for him to climb smoothly. This improves the anti-climbing performance of the guardrail and maintains a good protective state.
[0037] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-4 The rotating block 6, which is rotatably installed on the outer wall of the guardrail frame 2, protrudes from the end of the guardrail post 1 and is rotatably connected to the guardrail post 1. The guardrail frame 2 has a cross-shaped cross section, which fully covers the surrounding area and reduces blind spots. The rotating block 6, which is rotatably installed on the outer wall of the guardrail post 1, has the same function as the rotating block 6 on the outer wall of the guardrail frame 2. The workers use tools to turn the rotating blocks 6 one by one to control the movement of the subsequent moving rod 61.
[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-4 Multiple sets of perforated plates 5 are detachably installed on the guardrail frame 2. The multiple sets of perforated plates 5 are symmetrical to each other, and the outer wall of the perforated plate 5 is attached to the outer wall of the guardrail post 1 and the guardrail frame 2. The perforated plate 5 itself is full of holes, making it difficult for climbers to find suitable gripping points and footholds. In addition, the outer wall of the perforated plate 5 is in close contact with the outer wall of the guardrail post 1 and the guardrail frame 2, reducing the gaps and gaps that can be climbed, and effectively enhancing the overall anti-climbing performance of the guardrail.
[0039] Second embodiment:
[0040] Please see Figures 1-5 A movable rod 61 is slidably installed on the inner wall of the guardrail frame 2, and a rotating block 6 corresponding to the movable rod 61 is rotatably installed on the outer wall of the guardrail frame 2. This block is used to drive the movable rod 61 to slide. The movable rod 61 has a rack and pinion design at one end. The rotating block 6 has a gear design at one end near the guardrail frame 2 that meshes with the movable rod 61, and a cylindrical design at the other end. An operating hole is opened on the outer wall of the cylindrical end of the rotating block 6, realizing efficient linkage between the two. The operator only needs to use a tool to rotate the rotating block 6, and through the meshing transmission of the gear and rack, the movement can be precisely driven. The movable rod 61 slides on the inner wall of the guardrail post 1 to complete the installation of the perforated plate 5. A limit block 62 is installed on the outer wall of the movable rod 61, and a fixing block 51 corresponding to the limit block 62 is installed on the outer wall of the perforated plate 5 to restrict the limit block 62. This can effectively prevent the perforated plate 5 from shifting or loosening due to vibration, external impact, or other factors, thus ensuring the protective performance of the guardrail. In addition, a fixing groove 21 corresponding to the fixing block 51 is opened on the outer wall of the guardrail frame 2, which provides precise positioning for the installation of the perforated plate 5 and ensures that the perforated plate 5 can be stably installed on the outer wall of the guardrail frame 2.
[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5Multiple sets of fixing blocks 51 are symmetrically installed on the outer wall of the perforated plate 5, and each set of fixing blocks 51 has a limiting hole 52 corresponding to the moving rod 61. Pushing the perforated plate 5, the fixing blocks 51 enter the fixing groove 21, which improves the installation efficiency of the perforated plate 5 and helps to enhance the stability of the entire guardrail structure. The precise correspondence between the fixing blocks 51 and the fixing groove 21 makes the installation of the perforated plate 5 accurate and efficient, saving installation time and labor costs.
[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The fixing groove 21 is opened on the outer wall of both the guardrail post 1 and the guardrail frame 2, and the fixing groove 21 on the guardrail post 1 and the guardrail frame 2 are positioned correspondingly. Multiple sets of fixing groove 21 are equally spaced on the guardrail post 1 and the guardrail frame 2. The fixing block 51 cooperates with the fixing groove 21 to provide a reliable fixing method for the perforated plate 5. The moving rod 61 slidably installed on the inner wall of the guardrail post 1 works together with the moving rod 61 slidably installed on the inner wall of the guardrail frame 2 to provide stable installation support for the perforated plate 5.
[0043] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 Multiple sets of limiting blocks 62 are symmetrically installed on the outer wall of the moving rod 61, and the cross section of the limiting block 62 is L-shaped. When the moving rod 61 slides on the inner wall of the guardrail post 1, the L-shaped limiting block 62 can accurately fit into the limiting hole 52 to avoid deviation. The limiting block 62 tightly abuts against the edge of the limiting hole 52 to ensure the stability of the entire guardrail structure.
[0044] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-4 Figures 1-4 The movable rod 61 has a rack and pinion design at its end. The rotating block 6 has a gear design at one end near the guardrail frame 2 that meshes with the movable rod 61, and a cylindrical design at the other end. The outer wall of the cylindrical end of the rotating block 6 has an operating hole. The meshing structure of the gear and rack of the rotating block 6 and the movable rod 61 realizes efficient linkage between the two. The operator only needs to use a tool to rotate the rotating block 6. Through the meshing transmission of the gear and rack, the movable rod 61 can be accurately driven to slide on the inner wall of the guardrail post 1 to complete the installation of the perforated plate 5.
[0045] In practical operation, the guardrail post 1 serves as the vertical support for the entire guardrail structure, with a shaft 4 installed at its end. The two form a solid whole, providing a reliable foundation for the installation of subsequent components. The outer wall of the shaft 4 is connected to a round tube 41 via a bearing, allowing the round tube 41 to rotate flexibly around the shaft 4. Once a climber touches the round tube 41, the tube 41 will rotate due to the force, and the part that the climber originally planned to grab or step on will instantly lose stable support, making it difficult for the hands and feet to find a foothold, increasing the difficulty of climbing, interfering with the continuity of the climber's climbing movements, effectively preventing the climber from climbing over, and without causing serious injury to the climber.
[0046] The guardrail frame 2 has a cross-shaped design, which is compatible with the guardrail post 1 to ensure the continuity and stability of the overall structure. The flange 3 is located at the bottom of the guardrail post 1 and is tightly connected to the ground or other fixed foundation by bolts to firmly fix the guardrail in the predetermined position and prevent it from tilting or shifting. The outer walls of the guardrail post 1 and the guardrail frame 2 have fixing grooves 21. The fixing blocks 51 installed on the outer wall of the perforated plate 5 are aligned with the fixing grooves 21 and pushed into the inner walls of the guardrail post 1 and the guardrail frame 2. Then, using tools, the rotating blocks 6 installed on the outer walls of the guardrail frame 2 and the outer walls of the guardrail post 1 are turned one by one, so that they push the moving rod 61 to move through the tooth meshing, driving the limiting block 62 into the limiting hole 52. The 52 and the limiting block 62 work together to fix the perforated plate 5, effectively preventing the perforated plate 5 from shifting or loosening due to vibration, external impact, etc., ensuring the protective performance of the guardrail. At the same time, it can be quickly disassembled and installed during the transportation and handling of the anti-climb guardrail, reducing the difficulty of handling and reducing the risk of damage to the guardrail caused by collision and squeezing during handling. After the perforated plate 5 is installed, the outer wall of the perforated plate 5 will fit tightly with the outer wall of the guardrail post 1 and the guardrail frame 2. At the same time, the perforated plate 5 itself is full of holes, making it difficult for climbers to find suitable gripping points and footholds, reducing the gaps and gaps that can be climbed, and further enhancing the overall anti-climb performance of the guardrail.
