Technical Field

[0001] This utility model relates to the field of road safety protection technology, and in particular to a heavy-duty fence corner connector structure for temporary road construction safety protection. Background Technology

[0002] Road construction safety is a crucial measure to ensure the safety of personnel, equipment, and the construction site during the construction process. It not only concerns the lives of construction workers but also the quality of the project and its successful completion.

[0003] Heavy-duty road safety barriers are mainly used in road construction, areas prone to traffic accidents, and high-risk construction sites to ensure the safety isolation of the construction area from the driving lane and pedestrian walkway, thereby reducing the occurrence of accidents. However, the existing heavy-duty barrier corner connectors cannot rotate or move the heavy-duty barriers connected at both ends, thus making it impossible to flexibly adjust them according to the protection range.

[0004] To address the aforementioned issues, we propose a heavy-duty fence corner connector structure for safety protection during temporary road construction. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing a heavy-duty fence corner connector structure for temporary road construction safety protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heavy-duty fence corner connector structure for temporary road construction safety protection, comprising a main frame, a fixed post fixedly connected to the lower end of the main frame, three rotating parts rotatably sleeved on the fixed post, a movable connector fixedly connected to the left end of the three rotating parts, a first threaded rod threadedly connected to the lower end of the fixed post, a first rotating post fixedly connected to the lower end of the first threaded rod, a sliding sleeve slidably sleeved on the fixed post, and a friction ring fixedly connected to the upper end of the sliding sleeve.

[0007] In the aforementioned heavy-duty fence corner connector structure for temporary road construction safety protection, two fixing parts are fixedly sleeved on the fixing post, and the right ends of the two fixing parts are jointly fixedly connected to a fixing connector.

[0008] In the above-mentioned heavy-duty fence corner connector structure for temporary road construction safety protection, two support plates are fixedly connected between the left and right inner walls of the main frame, and a second threaded rod is rotatably connected between the two support plates. A second rotating column is rotatably connected to the upper end of the upper support plate, and the second rotating column is coaxially fixedly connected to the second threaded rod. A fixing block is fixedly connected to the lower end of the fixing member located below.

[0009] In the aforementioned heavy-duty fence corner connector structure for temporary road construction safety protection, both the front and rear ends of the fixing block are provided with slide rails, and a movable U-shaped frame is threaded onto the second threaded rod. Two sliders are fixedly connected to the movable U-shaped frame, and the two sliders are slidably connected to the two slide rails respectively.

[0010] In the aforementioned heavy-duty fence corner connector structure for temporary road construction safety protection, the lower end of the fixing plate is provided with casters.

[0011] In the aforementioned heavy-duty fence corner connector structure for temporary road construction safety protection, the friction ring is made of rubber, and the surface of the main frame is hot-dip galvanized.

[0012] Compared with existing technologies, the advantages of this heavy-duty fence corner connector structure for temporary road construction safety protection are:

[0013] This utility model allows the protective fence connected by the movable connector to be rotated and changed flexibly, thereby changing the protection range. The rotatable protective fence can be fixed by a friction ring, and the connected protective fence can be moved by casters. The height of the casters can be adjusted up and down to adapt to different situations. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1-3 A heavy-duty fence corner connector structure for temporary road construction safety protection includes a main frame 1. A fixed post 2 is fixedly connected to the lower end of the main frame 1. Three rotating parts 3 are rotatably sleeved on the fixed post 2. A movable connector 4 is fixedly connected to the left end of each of the three rotating parts 3. A first threaded rod 5 is threadedly connected to the lower end of the fixed post 2. A first rotating post 6 is fixedly connected to the lower end of the first threaded rod 5. A sliding sleeve 7 is slidably sleeved on the fixed post 2. A friction ring 8 is fixedly connected to the upper end of the sliding sleeve 7. Two fixing parts 9 are fixedly sleeved on the fixed post 2. The right end is fixedly connected to a fixed connector 10. The movable connector 4 can rotate by rotating the three rotating parts 3 on the fixed column 2, so that the protective fence connected by the movable connector 4 can rotate and change the protection range. The friction ring 8 is made of rubber and has high friction. By rotating the first rotating column 6, the first threaded rod 5 is driven to screw upward into the fixed column 2. The first rotating column 6 pushes the sliding sleeve 7 upward until the friction ring 8 abuts against the rotating part 3 at the bottom, thereby fixing the rotating part 3 and fixing the rotatable movable connector 4.

[0020] Two support plates 11 are fixedly connected between the left and right inner walls of the main frame 1. A second threaded rod 12 is rotatably connected between the two support plates 11. A second rotating column 13 is rotatably connected to the upper end of the upper support plate 11. The second rotating column 13 is coaxially fixedly connected to the second threaded rod 12. A fixing block 17 is fixedly connected to the lower end of the fixing member 9. Slide rails 18 are provided at both the front and rear ends of the fixing block 17. A movable U-shaped frame 14 is threaded onto the second threaded rod 12. Two sliders 19 are fixedly connected to the movable U-shaped frame 14. The two sliders 19 are respectively connected to two… The slide rail 18 is slidably connected, and the lower end of the movable U-shaped frame 14 is fixedly connected to the fixed plate 15. The lower end of the fixed plate 15 is provided with a universal wheel 16. Rotating the second rotating column 13 drives the second threaded rod 12 to rotate. The movable U-shaped frame 14 moves up and down through the limit of the two sliders 19 which are slidably connected to the two slide rails 18 respectively, thereby adjusting the height of the universal wheel 16.
