Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision post structures, specifically an anti-collision post structure for road traffic safety. Background Technology

[0002] In modern transportation infrastructure construction, road bollards, as important facilities for ensuring road safety, are widely used in various scenarios such as parking lots, sidewalks, and commercial areas. With the increasingly refined development of urban traffic planning and the growing diversity of road usage needs, the height requirements for bollards vary significantly across different roads: for example, roads around schools and hospitals require lower bollards to avoid visual obstruction and passage for pedestrians; while highway entrances and exits, logistics parks, and other areas require higher and more stable bollards to withstand accidental vehicle collisions.

[0003] However, the road bollards commonly found on the market today have certain drawbacks. Their height is fixed during production and cannot be flexibly adjusted according to the specific needs of the actual site. When the usage scenario changes or the road function is replanned, these fixed-height bollards are difficult to adapt to the new environmental requirements, leading to frequent replacements or idle waste. Therefore, the overall practicality of these bollards is not very good. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2 This utility model discloses a crash barrier structure for road traffic safety, comprising a fixed base 1 and a crash barrier post 2. The fixed base 1 has multiple mounting holes. Workers use expansion bolts to pass through these holes and install the crash barrier into the ground, fixing it in place at a designated location. Reflective stripes 11 are fitted into the center of the crash barrier post 2 for reflective purposes, facilitating driver visibility. An inner cavity is provided at the top of the crash barrier post 2, extending through the upper end face of the post. An internal thread 3 is provided on the inner wall of the inner cavity, and a connecting pipe 4 is threadedly connected to it. A height-increasing anti-collision device is fixed to the upper part of the connecting pipe 4. The impact post 5, through the threaded connection of the connecting pipe 4 and the internal thread 3, can be installed on the impact base post 2 to increase the overall height. The upper part of the impact post 5 is provided with another inner cavity, the upper part of which penetrates the upper end face of the impact post 5. Another internal thread 3 is provided on the inner wall of this inner cavity for connecting other connecting pipes 4. Multiple impact posts 5 can be installed on the impact base post 2 using the same threaded connection method. Then, they can be installed on the impact base post 2. Depending on the actual use scenario, different numbers of impact posts 5 can be installed to make the overall height meet the requirements of the use location.

[0029] The inner thread 3 of the upper cavity of the heightening anti-collision post 5 located at the top is threaded to the top cover 6. The top cover 6 is provided with a fixing ring. The worker grasps the fixing ring and moves the top cover 6 to the upper part of the heightening anti-collision post 5 at the top. It is installed on the top heightening anti-collision post 5 by means of threaded connection, thus blocking the inner cavity of the post.

[0030] The outer wall of the connecting pipe 4 is provided with an external thread 7 that is compatible with the internal thread 3, so that the threads can be connected together.

[0031] A support plate is fixedly installed on the side wall of the heightening anti-collision post 5. A connecting rod is rotatably connected to the middle of the support plate, and a handle 8 is fixed on the connecting rod. The operator rotates the handle 8 to a horizontal position, grasps the handle 8, and rotates it to facilitate the disassembly and installation of the heightening anti-collision post 5. The handle 8 has a slot 9 facing the side wall of the heightening anti-collision post 5. This snap-fit ​​structure design can easily and securely hold the handle 8 in a vertical position. The locking plate 10 is made of a flexible material, which will produce a moderate contraction deformation during the process of snapping into the slot 9. This deformation causes the locking plate 10 to generate an expansion force, which evenly squeezes the inner wall of the slot 9, thereby forming a strong and lasting reaction force to ensure that the handle 8 remains stable in the vertical direction and is not easy to shake or shift.

[0032] In summary, when using this crash barrier structure for road traffic safety, first confirm the usage location, check the multiple mounting holes on the fixing base 1, and prepare matching expansion bolts. Place the fixing base 1 at the designated installation position, aligning the mounting holes with the ground markings. Use tools to pass the expansion bolts through the mounting holes of the fixing base 1 one by one and screw them into the ground. Tighten the bolts until the fixing base 1 is firmly fixed to the ground, completing the basic fixing of the crash barrier. Then, select an appropriate number of extension crash barriers 5 according to the actual usage scenario's required crash barrier height. Align the external thread 7 on the outer wall of the connecting pipe 4 with the internal thread 3 on the inner wall of the inner cavity of the crash barrier base 2, and rotate the connecting pipe 4 clockwise. Through thread engagement, the connecting pipe 4 is firmly installed on the crash barrier base 2. Then, align the internal thread 3 of the bottom inner cavity of the extension crash barrier 5 with the external thread 7 on the top of the connecting pipe 4, and complete the connection by rotating clockwise. If more height is required, repeat the above operation and install multiple height-increasing anti-collision posts 5 in sequence. After all height-increasing anti-collision posts 5 are installed, grasp the fixing ring on the top of the top cover 6, align the external thread at the bottom of the top cover 6 with the internal thread 3 of the upper inner cavity of the top height-increasing anti-collision post 5, and rotate the top cover 6 clockwise to make it tightly installed on the top height-increasing anti-collision post 5, sealing the top inner cavity and playing a protective role such as dustproofing and waterproofing.
