[0002] In highway maintenance and construction operations, the rapid installation and stable fixation of temporary signs (such as construction signs and emergency signs) are crucial for ensuring traffic safety and information transmission. Currently, signs are mostly fixed to guardrail posts using methods such as wire binding, bolt tightening, or welding. However, these methods have the following drawbacks:

[0003] The wire binding method is prone to displacement or tilting under strong winds or vehicle vibrations, requiring frequent manual calibration. Wire binding carries the risk of structural damage, while welding may damage the surface coating of the guardrail post, leading to metal corrosion, reducing the service life of the guardrail, and resulting in insufficient stability.

[0004] Low installation efficiency: Traditional methods require multiple people to work together, are complex to operate, and take a long time, making it difficult to meet the needs of rapid deployment, especially in high traffic or emergency construction scenarios.

[0005] Therefore, there is an urgent need to design a sign fixing device and sign fixing system to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a sign fixing device and sign fixing system that are securely installed and have high installation efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides a sign fixing device, including a controllable magnet and a fixing base. The controllable magnet is used for magnetic connection with a guardrail post, and the fixing base has a fixing channel for the sign pole to pass through. The controllable magnet includes a first connecting part and a magnetic attracting part. The first connecting part is connected to the fixing base, and the magnetic attracting part is connected to the guardrail post. The controllable magnet is provided with a magnetic switch for controlling the presence or absence of magnetism. The fixing base includes a second connecting part and a pressing fixing part. The second connecting part is connected to the first connecting part. The pressing fixing part has a plurality of fixing holes, and the fixing holes are equipped with pressing members. The pressing members pass through the fixing holes to press the sign pole in the fixing channel.

[0008] As an improvement to the above solution, the fixing base also includes an elastic bushing, which is disposed between the signpost pole and the fixing channel.

[0009] As an improvement to the above solution, the first connecting part is provided with a plurality of protrusions, and the second connecting part is provided with connecting holes adapted to the protrusions.

[0010] As an improvement to the above solution, the shape of the magnetic suction part is adapted to the shape of the surface of the guardrail post, and the magnetic suction part is provided with anti-slip texture that contacts the guardrail post.

[0011] As an improvement to the above solution, the coefficient of friction between the magnetic attraction part and the guardrail post is greater than or equal to 0.4.

[0012] As an improvement to the above solution, the fixing hole is a threaded hole, and the top pressing member is a bolt equipped with a screw handle.

[0013] As an improvement to the above solution, the fixed channel includes two axisymmetric receiving surfaces, each receiving surface including a first arc surface and a first straight surface disposed on both sides of the first arc surface.

[0014] As an improvement to the above solution, the receiving surface further includes a second arc surface and a second straight surface that are sequentially connected to the first straight surface, and the two receiving surfaces are connected by their respective second straight surfaces.

[0015] Correspondingly, this utility model also discloses a sign fixing system, including the aforementioned sign fixing device, sign pole, and guardrail post.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0026] like Figure 1 As shown, the sign fixing device of this utility model includes a controllable magnet 1 and a fixing base 2. The controllable magnet 1 is used to magnetically connect with the guardrail post 3, and the fixing base 2 is provided with a fixing channel 21 for the sign pole 4 to pass through.

[0027] The controllable magnet 1 includes a first connecting part 11 and a magnetic attraction part 12. The first connecting part 11 is connected to the fixed base 2, and the magnetic attraction part 12 is connected to the guardrail post 4. The controllable magnet 1 is provided with a magnet switch 13 for controlling the presence or absence of magnetism.

[0028] The fixing base 2 includes a second connecting part 22 and a pressing fixing part 23. The second connecting part 22 is connected to the first connecting part 11. The pressing fixing part 23 has a plurality of fixing holes 231. Each fixing hole 231 is equipped with a pressing member 232. The pressing member 232 passes through the fixing hole 231 to press against the signpost 4 in the fixing channel. Preferably, the fixing hole is a threaded hole, and the pressing member is a bolt equipped with a screw handle, so that construction personnel can screw it in. The dynamic leveling function is achieved by manually screwing the screw handle, reducing the amount of manual calibration work.

[0029] It should be noted that, preferably, the fixing base 2 is made of 45# steel, which requires heat treatment and hardening process, and the surface is anodized to ensure its salt spray resistance reaches more than 1000 hours. The controllable magnet 1 integrates an electromagnetic control unit, and the magnet switch 13 can be manually turned, enabling the controllable magnet 1 to have a manual operation (manual switch) mode, which facilitates flexible control in different scenarios. Preferably, the controllable magnet 1 adopts sealed encapsulation technology to avoid magnetic attenuation caused by rainwater erosion and extend the service life of the system. The controllable magnet 1 integrates an electromagnetic control unit, and the presence or absence of magnetic force is controlled by the magnet switch 13: when there is no current, the controllable magnet 1 has magnetic force; when current is applied, the controllable magnet 1 does not have magnetic force. The specific principle of the controllable magnet 1 is existing technology.

[0030] This utility model sign fixing device is equipped with a controllable magnet 1 and a fixing base 2. The initial fixing is achieved by the magnetic attraction of the controllable magnet 1, and then radial pressure is applied by the top pressing fixing part 23 of the fixing base 2, so that the whole installation is firm. Moreover, the installation process does not require fixing operations such as iron wire, avoiding damage to the guardrail post structure and improving installation efficiency. The top pressing part 232 realizes the dynamic leveling function, reducing the amount of manual calibration work and the installation efficiency is high.

[0031] To reduce the impact of vibration, the mounting base 2 also includes an elastic bushing (not shown in the figure), which is located between the signpost pole 4 and the fixed channel 21.

[0032] It should be noted that the design of adding the matching elastic bushing between the signpost pole 4 and the fixed channel 21, after the top pressing member 232 passes through the fixed hole 231, it presses the elastic bushing in the fixed channel 21 and the signpost pole 4 in sequence, so that the signpost pole 4 is elastically connected with the fixed channel 21 and the top pressing member 232. This structure can effectively absorb the vibration energy generated when the vehicle passes through and prevent the signpost pole 4 from being displaced due to vibration.

[0033] Regarding the connection between the controllable magnet 1 and the fixed base 2, preferably, the first connecting part 11 is provided with a plurality of protrusions 111, and the second connecting part 22 is provided with connecting holes 221 adapted to the protrusions 111. The controllable magnet 1 and the fixed base 2 are connected to each other by connecting the protrusions 111 into the connecting holes 221. The specific connection method can be selected according to the usage requirements. For example, the protrusions 111 are fixedly set in the connecting holes 221, that is, the controllable magnet 1 and the fixed base 2 are fixedly connected, or after the protrusions 111 are connected to the connecting holes 221, they are connected by magnetic attraction between the controllable magnet 1 and the fixed base 2.

[0034] To increase anti-slip capability, the shape of the magnetic suction part 12 is adapted to the shape of the surface of the guardrail post 3 (taking a cylindrical guardrail post 3 as an example), and the magnetic suction part 12 is provided with anti-slip textures that contact the guardrail post 3. In actual use, through appropriate process design, the coefficient of friction between the magnetic suction part 12 and the guardrail post 3 can be greater than or equal to 0.4 to resist wind blowing in most situations.

[0035] like Figure 3 and Figure 4 As shown, in terms of the specific structure of the fixed base 2, preferably, the fixed channel 21 includes two axisymmetric receiving surfaces 211, the receiving surface 211 including a first arc surface 211a and a first straight surface 211b provided on both sides of the first arc surface 211a.

[0036] The receiving surface 211 also includes a second arc surface 211c and a second straight surface 211d that are sequentially connected to the first straight surface 211b, and the two receiving surfaces 211 are connected by their respective second straight surfaces 211d.

[0037] It should be noted that, as Figure 3 As shown, the two receiving surfaces 211 are symmetrical about the dividing line L.

[0038] The first arc surface 211a is the region between the dividing line L1 and the dividing line L2;

[0039] The first straight surface 211b is the area between the dividing line L1 and the dividing line L3 and the area between the dividing line L2 and the dividing line L4;

[0040] The second arc surface 211c is the area between the dividing line L3 and the dividing line L5 and the area between the dividing line L4 and the dividing line L6;

[0041] The second straight surface 211d is the area between the dividing line L5 and the dividing line L, and the area between the dividing line L6 and the dividing line L;

[0042] Combination Figure 3 and Figure 4 After the signpost 4 is installed into the fixing base 2 and the top pressure member 232 is tightened, a first partition space 24 and a second partition space 25 are formed between the receiving surface 211 and the signpost 4. The first partition space 24 and the second partition space 25 are conducive to further dissipating vibration energy. The vibration influence between the top pressure member 232 and the signpost 4 is reduced by the first partition space 24, and the vibration influence between the controllable magnet and the signpost 4 is reduced by the second partition space 25. With the cooperation of the elastic bushing (not shown in the figure), the impact of vibration on the signpost can be effectively reduced. In addition, the first partition space 24 is conducive to strengthening the connection between the top pressure member 232 and the fixing base 2.

[0043] More preferably, the length of the first straight surface 211b between the dividing line L2 and the dividing line L4 is greater than the length of the first straight surface 211b between the dividing line L1 and the dividing line L3, so that the second dividing space 25 is greater than the first dividing space 24, which can further reduce the impact of the vibration of the controllable magnet 1 on the signpost 4.

[0044] Correspondingly, this utility model also discloses a sign fixing system, such as Figure 1 and Figure 5 As shown, the sign fixing system includes the aforementioned sign fixing device 5, sign pole 4, and guardrail post 3. The sign pole 4 is used to fix the sign 6, and the guardrail post 3 is fixedly installed. Several sign fixing devices 5 are provided, and the number can be selected according to actual usage needs.

[0045] The signpost 4 is located in the fixed channel 21 of the sign fixing device 5, and the guardrail post 3 is magnetically connected to the controllable magnet 1 of the sign fixing device 5.

[0046] The signpost 4 is a hollow tube, and a magnetic adapter (not shown in the figure) is provided at the bottom of the signpost 4 to facilitate the connection of the signpost 4 into the fixing channel 21 of the sign fixing device 5, so that the signpost 4 can be quickly plugged into and unplugged from the fixing base 4.

[0047] Preferably, the signpost 4 is made of hollow carbon steel pipe with a wall thickness of not less than 2-3 mm.

[0048] In summary, the sign fixing device of this utility model includes a controllable magnet 1 and a fixing base 2. Initial fixing is achieved through the magnetic attraction of the controllable magnet 1, followed by radial pressure applied by the top-pressing fixing part 23 of the fixing base 2, resulting in a secure overall installation. Furthermore, the installation process eliminates the need for fixing with wires or other materials, avoiding damage to the guardrail structure and improving installation efficiency. The top-pressing part 232 enables dynamic leveling, reducing manual calibration workload and further enhancing installation efficiency. Moreover, the design of the anti-slip texture, elastic bushing, and receiving surface 211 in the magnetic attraction part 12 reduces the impact of vibration on the sign pole 4, ensuring stable fixing of the sign.

[0049] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
