Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1-9 shown, a fuel delivery pipe for an automobile includes: a pipe body 1, a positioning seat 6, and a dust cap 4,

[0032] Both ends of the pipe body 1 are fixedly connected with connecting pipes 2 respectively. The connecting pipes 2 are fitted and connected with mounting pipes 3. A rotating base 7 is fixedly connected to the side end of the mounting pipe 3. There are two groups of positioning seats 6 which are respectively fixedly connected to both ends of the connecting pipe 2. A positioning component is fitted and connected in the positioning seat 6. The positioning component is fitted and connected with the rotating base 7. When it is necessary to install the pipe body 1 on the vehicle, align the mounting pipe 3 with the connection position of the vehicle, and then rotate the mounting pipe 3. The mounting pipe 3 drives the rotating base 7 to rotate, and the mounting pipe 3 is installed at the connection position of the vehicle. When the mounting pipe 3 stops rotating, install the positioning component. The positioning component positions the rotating base 7, and the positioning effect of the positioning component on the rotating base 7 is transmitted to the mounting pipe 3. When the vehicle vibrates during operation, the mounting pipe 3 can avoid the phenomenon of self-rotation due to the positioning effect provided by the positioning component, thus ensuring the stability of the mounting pipe 3 installed on the vehicle, and avoiding the phenomenon of fuel leakage caused by the detachment of the mounting pipe 3;

[0033] A dust cap 4 is fixedly connected to the outer wall of the mounting pipe 3. When the mounting pipe 3 rotates, the mounting pipe 3 drives the dust cap 4 to rotate. When the mounting pipe 3 is installed on the vehicle, the dust cap 4 abuts against the connection position of the vehicle. The dust cap 4 has elasticity, and the dust cap 4 seals and covers the connection position of the mounting pipe 3 and the vehicle, avoiding external dust from entering the connection position of the mounting pipe 3 and the vehicle, and ensuring the cleanliness of the connection position of the mounting pipe 3 and the vehicle.

[0034] In some specific implementation schemes, a rotating groove 18 is formed inside the connecting pipe 2. Grooves are respectively formed at the upper and lower ends of the connecting pipe 2. The rotating base 7 is clamped and connected in the rotating groove 18 and is rotatably connected with the inner wall of the rotating groove 18. When the mounting pipe 3 rotates, the mounting pipe 3 drives the rotating base 7 to rotate along the inner wall of the rotating groove 18. The clamping connection between the rotating base 7 and the inner wall of the rotating groove 18 connects the connecting pipe 2 and the mounting pipe 3 together. When the mounting pipe 3 is fixed on the vehicle, the mounting pipe 3 fixes the pipe body 1 through the connecting pipe 2, thus ensuring the effect that the vehicle can transport fuel through the connecting pipe 2 and the pipe body 1.

[0035] In some specific implementation schemes, a sensor 10 is provided in the groove. A buffer pad 9 is provided between the sensor 10 and the inner wall of the groove. Both ends of the buffer pad 9 are fixedly connected with the sensor 10 and the groove respectively. In order to avoid the problem that when the vehicle is in use, the fuel pressure changes when the fuel passes through the pipe body 1 and it cannot be detected. When the fuel passes through the pipe body 1, the sensor 10 detects the pressure of the fuel, and the sensor 10 displays the data of the fuel pressure detection through a display screen of the existing technology, which is beneficial for the user to monitor the fuel pressure transported in the pipe body 1 in time. Among them, the buffer pad 9 has plasticity. When the vehicle vibrates during operation, the buffer pad 9 buffers the vibration and avoids the vibration from damaging the sensor 10.

[0036] In some specific embodiments, the positioning component includes: a pull plate 5, a spring 11, a holding plate 12 and a positioning post 15. The holding plate 12 is fixedly connected to the outer wall of the positioning post 15, and the holding plate 12 is in abutting connection with the inner wall of the positioning seat 6. Both ends of the spring 11 are fixedly connected to the inner wall of the positioning seat 6 and the side end of the holding plate 12 respectively. The rotating seat 7 is axially provided with a plurality of positioning holes 8, and the positioning post 15 is matched with the positioning holes 8. The side end of the positioning post 15 is fixedly connected to the pull plate 5. When the installation pipe 3 is rotationally installed, the worker controls the pull plate 5 to pull the positioning post 15 to release the abutting effect between the positioning post 15 and the inner wall of the positioning hole 8. After the installation pipe 3 is rotationally installed at the connection of the vehicle, the worker releases the pull plate 5, and the elastic force of the spring 11 abuts against the holding plate 12, and the holding plate 12 drives the positioning post 15 to move. When the positioning post 15 abuts against the inner wall of the positioning hole 8, the positioning post 15 provides a positioning function for the rotating seat 7. Among them, the spring 11 provides an elastic abutting effect for the positioning post 15 through the holding plate 12, thereby avoiding the phenomenon that the positioning post 15 slides out of the positioning hole 8. When the vehicle vibrates during operation, the spring 11 plays a role in buffering the vibration, further ensuring the stability of the positioning post 15 in positioning the rotating seat 7.

[0037] In some specific embodiments, limit posts 13 are respectively fixedly connected to the upper and lower sides of the side end of the pull plate 5, and limit holes 14 are respectively opened on the upper and lower sides of the side end of the positioning seat 6. The limit posts 13 are in abutting connection with the inner walls of the limit holes 14. When the positioning post 15 abuts against the inner wall of the positioning hole 8, the pull plate 5 and the positioning seat 6 are in abutment. Among them, the pull plate 5 drives the limit posts 13 to be inserted into the limit holes 14, and the abutting between the limit posts 13 and the inner walls of the limit holes 14 provides a limiting function for the pull plate 5, thereby avoiding the phenomenon that the positioning post 15 rotates automatically due to vibration.

[0038] In some specific embodiments, the side end of the installation pipe 3 is rotatably connected to the connection pipe 2. One end of the installation pipe 3 away from the connection pipe 2 is fixedly connected with an installation cap 16. The installation cap 16 is in the shape of a nut, and a threaded hole 17 is opened through the inner wall of the installation pipe 3 in the inner wall of the installation cap 16. To facilitate the installation of the installation pipe 3, the worker controls the installation of the installation cap 16, and the installation cap 16 drives the installation pipe 3 to be installed. The threaded hole 17 opened in the inner walls of the installation pipe 3 and the installation cap 16 is threadedly connected to the connection of the vehicle.

[0039] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
