Description

Technical Field

[0001] This utility model relates to the field of fixing devices for warning signs, specifically fixing devices for traffic safety warning signs. Background Technology

[0002] Traffic safety warning signs are typically mounted on posts using fixing devices to alert drivers to road conditions. In existing technology, the fixing devices often employ a semi-circular snap-fit ​​structure, where the warning sign is connected to the snap-fit ​​using bolts, and the snap-fit ​​is then secured to the post.

[0003] The existing fixing devices have the following shortcomings: First, the bolts are prone to loosening under long-term vibration, causing the warning signs to fall off; second, the contact surface between the buckle and the column is smooth, with low friction, making it easy to slip and affecting stability. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for traffic safety warning signs, which has an added anti-loosening locking mechanism, improves the stability of the fixing device, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for traffic safety warning signs, including a buckle, an anti-slip protrusion on one side of the outer surface of the buckle, and second bolt holes on both sides of the buckle. It also includes a connecting aluminum rod, which is disposed at the front end of the buckle. A second bolt is installed between the connecting aluminum rod and the buckle. A first bolt hole is provided on the connecting aluminum rod, and the second bolt passes through the first bolt hole and the second bolt hole to connect the connecting aluminum rod and the buckle.

[0006] Furthermore, an anti-loosening locking mechanism is installed on the second bolt of the buckle, and the anti-loosening locking mechanism is connected to the second bolt for limiting.

[0007] Furthermore, the anti-loosening locking mechanism is equipped with limit nuts at both ends, and the limit nuts are integrally formed with the anti-loosening locking mechanism.

[0008] Furthermore, a limiting hole is provided at the front end of the limiting nut. The shape of the limiting hole is the same as that of the second bolt nut. The anti-loosening locking mechanism consists of the limiting nut, the limiting hole, and a magnet. After the second bolt passes through the second bolt hole provided on the buckle and the connection between the buckle, the column, and the warning sign is completed, the limiting hole is aligned with the nut of the second bolt, and the anti-loosening locking mechanism is put on the nut, locking the second bolts on both sides. If the warning sign is impacted or shaken, the two second bolts may rotate and loosen, but the anti-loosening locking mechanism will lock the nuts of the two bolts, and the two bolts will generate opposite forces to each other, thereby preventing rotation.

[0009] Furthermore, a magnet is installed around the limiting hole of the limiting nut, and the magnet is bonded to the limiting nut. The magnet can strengthen the connection between the two when the anti-loosening locking mechanism is put on the second bolt, and prevent the anti-loosening locking mechanism from falling off the bolt.

[0010] Furthermore, a first bolt is installed in the first bolt hole opened on the connecting aluminum rod.

[0011] Furthermore, a first nut is installed on one end of the first bolt, and the first nut is threadedly connected to the first bolt.

[0012] Furthermore, a second nut is installed on one end of the second bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model enhances the fit between the buckle and the column by setting anti-slip protrusions on one side of the buckle, preventing slippage. It also features an anti-loosening locking mechanism that effectively locks the nut when the warning sign is impacted or shaken. Furthermore, the installation process between the anti-loosening locking mechanism and the nut is simple and easy to operate. Attached Figure Description

[0016] 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.

[0017] To address the shortcomings of existing fixing devices, namely the tendency for bolts to loosen under prolonged vibration, causing warning signs to detach, and the smooth, low-friction surface between the clips and the column leading to slippage and instability, this embodiment provides the following technical solution: Example 1 Figures 1-5 As shown, the device of this utility model mainly consists of a connecting aluminum rod 1, a first bolt 2, a second bolt 3, a buckle 4, and an anti-loosening locking mechanism 5. The buckle 4 is approximately semi-circular in structure, used to grip the column. Its inner surface is provided with anti-slip protrusions 402 to increase friction, and second bolt holes 401 are provided on both sides. The connecting aluminum rod 1 is located at the front end of the buckle 4 and is used to install a warning sign. It has a first bolt hole 101. The second bolt 3 passes through the first bolt hole 101 of the connecting aluminum rod 1 and the second bolt hole 401 of the buckle 4, connecting the two and locking them with a second nut 301. The warning sign is fixed to the connecting aluminum rod 1 by the first bolt 2 and the first nut 201.

[0018] During the installation process, the worker first attaches the clip 4 to the post where the warning sign needs to be installed, ensuring the inner anti-slip protrusion 402 is in close contact with the post surface. Then, the connecting aluminum rod 1 with the warning sign already installed is placed at the front end of the clip 4, aligning the bolt holes. Next, the second bolt 3 is passed through the first bolt hole 101 and the second bolt hole 401 in sequence, and initially tightened with the second nut 301. Finally, the anti-loosening locking mechanism 5 is installed on the nuts of the second bolts 3 on both sides to complete the fixation. This basic structure effectively prevents relative sliding between the clip 4 and the post through the anti-slip protrusion 402.

[0019] Please refer to Example 2 Figure 1 - Figure 5 Based on Embodiment 1, a detailed anti-loosening locking mechanism 5 is added to further improve the anti-loosening safety and long-term stability of the device. The anti-loosening locking mechanism 5 has a limit nut 501 integrally provided at both ends. Each limit nut 501 has a limit hole 502 at its front end that matches the shape of the second bolt 3 nut, and a magnet 503 is attached around the limit hole 502.

[0020] The basic installation steps are the same as in Example 1. After tightening the second bolt 3, the key improvement lies in installing the anti-loosening locking mechanism 5: the two limiting holes 502 are aligned with the nuts of the second bolts 3 on both sides, allowing the magnet 503 to adhere to the nuts, thus securely mounting the anti-loosening locking mechanism 5 around the two nuts. When the warning sign is subjected to external impact or prolonged vibration, a single second bolt 3 may tend to rotate, but the anti-loosening locking mechanism 5, through its rigid structure, locks the nuts of both second bolts 3 together, restricting them from rotating independently, thus achieving an effective anti-loosening effect. The adsorption effect of the magnet 503 further prevents the anti-loosening locking mechanism 5 from falling off during vibration.

[0021] The working principle described above is as follows: First, the worker secures the warning sign to the connecting aluminum rod 1 using the first bolt 2 and the first nut 201. Then, the buckle 4 is engaged with the column, utilizing the anti-slip protrusions 402 on its inner side to increase friction and prevent initial slippage. Next, the connecting aluminum rod 1 is aligned with the buckle 4, and the two are initially tightened using the second bolt 3 and the second nut 301. Finally, the core anti-loosening locking mechanism 5 is installed on the nuts of the second bolts 3 on both sides, using the limiting holes 502 to hold the nuts in place, and further secured with magnets 503. This device innovatively employs a dual anti-loosening strategy combining mechanical interlocking and magnetic assistance. When subjected to vibration or impact, the anti-loosening locking mechanism 5 effectively prevents the second bolts 3 from rotating and loosening, thus ensuring the long-term stable installation of the warning sign in complex environments.

[0022] Based on Embodiments 1 and 2, the following materials can be used for key components to enhance performance: the main body of the connecting aluminum rod 1 and the buckle 4 can be made of aluminum alloy to ensure strength while reducing overall weight; the anti-slip protrusion 402 can be made of wear-resistant rubber or engineering plastic to provide sufficient friction while avoiding scratching the column surface; the second bolt 3, the first bolt 2 and their nuts can be made of galvanized steel or stainless steel to prevent corrosion; the anti-loosening locking mechanism 5 can be injection molded from high-strength engineering plastics (such as nylon or ABS), and the magnet 503 inside the limiting nut 501 can be a neodymium iron boron strong magnet to ensure firm adsorption. The appropriate selection of materials enables the device to adapt to harsh outdoor environments exposed to sun and rain, resulting in a longer service life and higher reliability.
