The obliquely arranged fixing groove can better fit the shape of the fuel pipe and provide more stable support and fixing effect. During vehicle driving, even if subjected to bumps and vibrations, the obliquely arranged fixing groove can effectively prevent the fuel pipe from being displaced in the horizontal and vertical directions, ensuring the stability of the fuel pipe connection, the second fixing groove is hingedly connected with a semicircular plate inside, the semicircular plate engages with the other fuel pipe, and the inner walls of the first fixing groove and the semicircular plate are provided with shock-absorbing cotton. The connecting bracket further includes a fixing member for fixing the semicircular plate. The design of the semicircular plate makes the fixing of the fuel pipe more stable, and the hinged connection facilitates the user to support the fuel pipe at different positions. The fixing member firmly fixes the semicircular plate, ensuring that the semicircular plate does not loosen or displace when fixing the fuel pipe, maintaining the stable support effect on the fuel pipe. The shock-absorbing cotton can effectively absorb the vibration generated during vehicle driving, reducing the friction and wear between the fuel pipe and the fixing groove and the semicircular plate. This not only prolongs the service life of the fuel pipe and the connecting bracket, but also reduces the noise generated by friction, improving the quietness of the vehicle. At the same time, the presence of shock-absorbing cotton can also alleviate the loosening of the fuel pipe caused by vibration, further ensuring the safety of fuel transmission.
[0007] Further, the back of the semicircular plate is provided with a connecting block, a pair of fixing blocks are installed in the second fixing groove, and a rotating shaft is connected between the pair of fixing blocks.

[0009] Further, a shock pad is installed in the mounting portion, and the shock pad is U-shaped, which can better fit the contact part of the connecting bracket and the vehicle body, effectively absorb the impact force generated between the connecting bracket and the vehicle body due to vibration, further reduce the influence of vibration on the fuel pipeline assembly during vehicle driving, and enhance the stability of the whole system.
[0010] Further, the inner walls of the pair of fuel pipes are coated with a corrosion-resistant coating, which can effectively prevent corrosion of the fuel on the inner walls of the fuel pipes, prolong the service life of the fuel pipes, reduce the risk of fuel leakage caused by corrosion of the fuel, and ensure the safety and reliability of fuel transmission.
[0011] Further, the pair of fuel pipes are made of metal, which has high strength and rigidity, can withstand the pressure of fuel and various external forces during vehicle driving, ensures the normal use of the fuel pipes under complex working conditions, and is not easy to deform or be damaged.
[0012] Compared with the prior art, the metal pipeline assembly for the fuel system has the following advantages: the semi-arc plate not only supports the fuel pipe, but also can be flexibly adjusted in position to adapt to fuel pipes at different positions due to its rotatable property. In the complex layout of the automobile fuel system, there may be slight differences in the positions of fuel pipes of different vehicle models or different batches of the same vehicle model. The rotatable design of the semi-arc plate makes the metal pipeline assembly have stronger universality and adaptability, and can be widely applied to various automobile fuel systems, improving the market applicability of the product. The semi-arc plate is firmly fixed by the fixing piece after rotation, so that the semi-arc plate does not loosen or displace during vehicle driving, and always maintains the stable supporting effect on the fuel pipe. This fixing method is simple and effective, and can be flexibly adjusted according to the actual installation situation, so that the fuel pipe can be reliably fixed under various working conditions. The shock-absorbing cotton in the first fixing groove and the inner wall of the semi-arc plate can effectively absorb the vibration of the vehicle during driving, and reduce the friction and wear between the fuel pipe and the fixing groove and the semi-arc plate. This not only prolongs the service life of the fuel pipe and the connecting bracket, reduces the maintenance cost, but also reduces the risk of failure caused by component wear, and improves the reliability of the whole fuel pipeline assembly.

[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0020] Please refer to Figure 1 - Figure 5 The utility model provides a technical scheme: a metal pipeline assembly for fuel system, comprising the following steps:
[0021] Two parallel fuel pipes 100 with multiple bending parts are assembled with the connecting support 200. One of the fuel pipes is clamped into the first fixing groove 2004, and the first fixing groove is arranged obliquely downward, which can closely fit the shape of the fuel pipe and provide stable support. In the second fixing groove 2005, the semicircular plate 2006 is rotatably installed on the rotating shaft 2010 through the connecting block 2011, and the rotating shaft is located between a pair of fixing blocks 2009. The other fuel pipe is placed in the appropriate position, and the semicircular plate 2006 is rotated to be clamped with the fuel pipe. Then, the bolt 2008 is used as a fixing member, the bolt is passed through the fixing part and is screwed with the second fixing groove 2005, the bolt is tightened to press the semicircular plate 2006, and the semicircular plate is firmly fixed with the fuel pipe and cannot be rotated randomly. At the same time, the shock cotton in the inner walls of the first fixing groove 2004 and the semicircular plate 2006 closely fits the fuel pipe, which further stabilizes the position of the fuel pipe while reducing the vibration friction.
[0022] The mounting portion of the connecting bracket 200 is connected with the automobile body through the fixing hole 2003. During installation, appropriate connecting components such as screws and nuts are selected, the screws are passed through the fixing hole 2003 and are screwed on the preset mounting point of the automobile body. The U-shaped shock-absorbing pad 2002 inside the mounting portion plays a role during connection, which tightly adheres to the contact position between the connecting bracket and the automobile body, effectively absorbs the impact force generated between the connecting bracket and the automobile body due to vibration, and enhances the stability of the entire metal pipeline assembly installation.
[0023] During vehicle driving, after the automobile engine is started, fuel is delivered from the fuel tank to the engine through the fuel pipe 100. Since the inner wall of the fuel pipe 100 is coated with a corrosion-resistant coating, it can effectively prevent corrosion of the fuel and ensure stable transmission of the fuel in the pipe. The vibration generated during vehicle driving is transmitted to the connecting bracket 200 through the automobile body. At this time, the first fixing groove 2004 and the shock-absorbing cotton inside the inner wall of the semi-arc plate 2006 begin to play a role, absorbing vibration energy and reducing friction and wear between the fuel pipe and the fixing groove and the semi-arc plate. At the same time, the U-shaped shock-absorbing pad 2002 also continuously buffers the vibration between the connecting bracket and the automobile body, ensuring that the entire metal pipeline assembly can still work stably in a vibrating environment, avoiding loosening, displacement and other situations of the fuel pipe, and ensuring the safety and stability of fuel transmission.
[0024] When the fuel pipe 100 needs to be repaired or replaced, the maintenance personnel first loosen the bolts 2008, so that the semi-arc plate 2006 loses the extrusion fixing force, and then rotate the semi-arc plate 2006, so that the fuel pipe to be repaired or replaced can be conveniently taken out. When installing a new fuel pipe, the reverse steps are followed, i.e., the new fuel pipe is placed in the appropriate position, the semi-arc plate 2006 is rotated to engage the fuel pipe, and then the bolts 2008 are tightened to fix the semi-arc plate. The entire repair and replacement process is simple to operate, effectively shortens the repair time and improves the repair efficiency.
