When transporting the fuel, a corrugated oil pipe is generally used for transportation. The corrugated structure of the oil pipe can ensure that the pipe has the characteristic of good bending strength.

[0003] The improvement of the pressure resistance of existing pressure-resistant fuel pipes generally relies mainly on strengthening the structural strength of the pipe wall, but this design can only effectively respond to and resist pressure shocks from the inside to the outside, and cannot resist pressure invasion from the outside to the inside. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a pressure-resistant fuel oil pipe to solve the technical problem that the reinforced pipe wall can only effectively cope with and resist the pressure impact from the inside to the outside.

[0007] Furthermore, an oil hole is provided on the fixing plate, and a plurality of the oil holes are provided, and the plurality of the oil holes are evenly arranged in a ring shape.

[0011] Furthermore, a spring sleeve rod is fixedly connected to one side of the tube wall, a clamping ring is fixedly connected to one end of the spring sleeve rod, and the clamping ring is in a semi-annular structure.

[0015] Furthermore, two spring sleeve rods are provided, and the two spring sleeve rods are arranged in a mirror image structure.

[0016] By adopting the above technical solution, the mirror image arrangement of the two spring sleeve rods ensures the stable engagement of the pull rope, ensures that the pull rope can be stably clamped after being fixed, and prevents the pull rope from falling off under the impact of oil.

[0017] Furthermore, one end of the connecting rod is rotatably connected to a mounting ring, and one side of the mounting ring is fixedly connected to a force transmission network.

[0020] By adopting the above technical solution, the uniform annular layout of the through holes ensures that the fuel can be evenly distributed when passing through the power transmission network, which helps to balance the pressure of the internal fuel flow and reduce local pressure peaks, thereby improving the stability and efficiency of fuel transmission.

[0021] Furthermore, a clamping rod is fixedly connected to one side of the tube wall, and the clamping rods are provided in multiple groups, with four clamping rods in each group.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A pressure-resistant fuel oil pipe, such as Figure 1-Figure 4 As shown, it includes a tube wall 1, and a pressure-resistant mechanism 2 is fixedly connected inside the tube wall 1. The pressure-resistant mechanism 2 includes a connecting block 201, and a connecting rod 202 is rotatably connected to the bottom of the connecting block 201. One end of the connecting rod 202 is rotatably connected to a fixing plate 3, and a fixing hole 4 is opened inside the fixing plate 3. A pull rope 5 is fixedly connected inside the fixing hole 4, and a protective film 6 is fixedly connected to the top of the connecting block 201. By arranging the pressure-resistant mechanism 2 in the tube wall 1, the oil pipe can withstand higher internal and external pressures, prevent deformation or rupture under extreme working conditions, ensure the safe flow of fuel, and provide an effective internal support structure, which can enhance the pressure resistance of the fuel oil pipe. At the same time, the connecting block 201 realizes a dynamic adjustment mechanism through the rotational connection between the connecting rod 202 and the fixing plate 3, so that when the oil pipe is subjected to different degrees of internal and external pressures, it can be supported or tightened by adjusting the pull rope 5 and then controlling the angle of the connecting rod 202, thereby adjusting the tension of the tube wall 1, thereby increasing the adaptability of the oil pipe and being able to flexibly respond according to actual use conditions.

[0038] See also Figure 1 and Figure 2The fixing plate 3 is provided with an oil hole 7, and a plurality of oil holes 7 are provided. The plurality of oil holes 7 are evenly arranged in a ring shape. The existence of the oil holes 7 enables the fuel to flow more smoothly when passing through the pressure-resistant fuel oil pipe. The design of the evenly arranged ring shape ensures the uniformity of the flow of the fuel in the pipe, reduces the flow resistance, and improves the efficiency of fuel transportation. The plurality of oil holes 7 can effectively disperse the pressure generated when the fuel flows, prevent the fixing plate 3 and other components from being damaged due to the direct impact of the high-pressure fuel, help protect the internal structure of the oil pipe, and extend the service life of the oil pipe.

[0039] See also Figure 1 and Figure 2 There are multiple pressure-resistant mechanisms 2, and the multiple pressure-resistant mechanisms 2 are rotatably connected to the fixing plate 3. The multiple pressure-resistant mechanisms 2 are evenly arranged in a ring shape. The evenly arranged ring shape of the multiple pressure-resistant mechanisms 2 ensures that the pressure inside the oil pipe can be evenly distributed around the entire pipe wall 1, which helps to prevent local overload and reduce deformation or damage of the pipe wall caused by uneven pressure, thereby improving the overall pressure resistance and durability of the fuel oil pipe. At the same time, the rotatable connection design between each pressure-resistant mechanism 2 and the fixing plate 3 allows the pressure-resistant mechanism 2 to be properly adjusted in position when subjected to external force, so that the oil pipe can more effectively adapt to changes in internal fuel pressure and the pressure influence of the external environment, thereby enhancing the adaptability and reliability of the oil pipe.

[0040] See also Figure 1 and Figure 2 A spring sleeve rod 8 is fixedly connected to one side of the tube wall 1, and a clamping ring 9 is fixedly connected to one end of the spring sleeve rod 8. The clamping ring 9 has a semi-annular structure. The setting of the spring sleeve rod 8 provides a support point for the clamping ring 9, ensuring that the clamping ring 9 can remain in the original position to achieve locking stability. At the same time, the semi-annular structure of the clamping ring 9 provides a convenient connection method, which is convenient for locking the pull rope 5 in the specified position and can be easily released when needed, which not only improves the adjustment efficiency of the pull rope 5, but also ensures the locking stability.

[0041] See also Figure 1 and Figure 2 A slot 10 is provided at one end of the pull rope 5, and the slot 10 and the snap ring 9 are matched, providing a simple and reliable way to adjust the position and tension of the pressure-resistant mechanism 2. By adjusting the pull rope 5 to make the slot 10 and the snap ring 9 engage, the user can easily adjust the pressure-resistant mechanism 2 inside the oil pipe as needed, thereby optimizing the oil pipe's resistance to internal fuel pressure and ensuring the stability and safety of the oil pipe under different pressure conditions. The adaptive connection design of the slot 10 and the snap ring 9 can also achieve firm locking, ensuring that the oil pipe can maintain good performance under various working conditions.

[0042] See also Figure 1 and Figure 2There are two spring sleeve rods 8, and the two spring sleeve rods 8 are arranged in a mirror structure. The mirror arrangement of the two spring sleeve rods 8 ensures the stable engagement of the pull rope 5, and ensures that the pull rope 5 can be stably clamped after being fixed, preventing the pull rope 5 from falling off under the impact of oil. At the same time, the spring sleeve rods 8 arranged in the mirror structure provide double elastic support, which enhances the locking of the pull rope 5, so that it can be stably locked in a complex oil environment, and the reliability of locking is improved.

[0043] The implementation principle of the utility model is as follows: first, when high-pressure oil needs to be filled, the position of the clamping groove 10 on the pull rope 5 is adjusted so that the clamping groove 10 and the clamping ring 9 on the spring sleeve rod 8 are engaged with each other, thereby driving the fixing plate 3 to move forward, so that the connecting rod 202 pulls the connecting block 201 to move inwardly of the pipe, so that an inward force is pre-applied on the pipe wall 1;

[0044] When high-pressure fuel is filled, the pressure of the fuel itself is applied to the tube wall 1, and the pressure is balanced with the inward force applied to the tube wall 1 in advance, so as to resist the internal oil pressure. Meanwhile, the oil hole 7 can reduce the impact force of the high-pressure fuel on the fixing plate 3.

[0045] When there is external pressure, the position of the slot 10 on the pull rope 5 is adjusted so that the connecting rod 202 can maintain a vertical state. At this time, the connecting block 201 and the protective film 6 provide a force to resist the external pressure.

[0046] Embodiment 2:

[0047] See also Figure 3 and Figure 4 One end of the connecting rod 202 is rotatably connected to a mounting ring 11, and one side of the mounting ring 11 is fixedly connected to a force transmission network 12. The rotatable connection of the mounting ring 11 allows the force transmission network 12 made of hard material to drive the connecting rod 202 to make corresponding position adjustments during movement, so that the oil pipe can pre-adjust the pressure in advance, more effectively adapt to changes in internal fuel pressure and the pressure influence of the external environment, and enhance the adaptability and reliability of the oil pipe. At the same time, the force transmission network 12 provides an additional structural layer for enhancing the overall structural strength of the oil pipe, which not only improves the pressure resistance of the oil pipe, but also improves the stability and safety of the oil pipe.

[0048] See also Figure 3 and Figure 4A through hole 13 is provided on the force transmission network 12, and a plurality of through holes 13 are provided. The plurality of through holes 13 are evenly arranged in a ring shape. The annular uniform layout of the through holes 13 ensures that the fuel can be evenly distributed when passing through the force transmission network 12, which helps to balance the pressure of the internal fuel flow and reduce the local pressure peak, thereby improving the stability and efficiency of the fuel transmission. At the same time, the presence of the plurality of through holes 13 allows the fuel to have more flow paths at the force transmission network 12, which helps to form a more balanced force distribution on the force transmission network 12 during the fuel flow process, thereby helping to reduce the vibration and noise caused by the fuel flow and improve the overall working environment of the oil pipe system.

[0049] See also Figure 3 and Figure 4 A clamping rod 14 is fixedly connected to one side of the pipe wall 1. The clamping rod 14 is arranged in multiple groups, and each group of clamping rods 14 is arranged with four. The arrangement of multiple groups of four clamping rods 14 enhances the structural stability and connection strength of the oil pipe, can evenly disperse the force on the connection point, and reduce the excessive local stress caused by concentrated load, thereby improving the durability and compression resistance of the connection point with the force transmission network 12 under high pressure conditions. At the same time, the configuration of four clamping rods 14 provides more fixing points, making the connection between the oil pipe and the force transmission network 12 more secure.

[0050] See also Figure 3 and Figure 4 The four clamping rods 14 are evenly arranged in a ring shape, and the clamping rods 14 and the through holes 13 are adapted to each other. The clamping rods 14 evenly arranged in a ring shape provide reliable fixation of the oil pipe and the force transmission network 12 to prevent them from falling off due to pressure changes or external impacts, thereby ensuring the installation safety of the pressure-resistant mechanism 2. At the same time, the adaptive design of the clamping rods 14 and the through holes 13 enables the oil pipe to fit more tightly and accurately when connected, further improving the connection reliability, effectively preventing the force transmission network 12 from falling off, and ensuring the safety of the system.

[0051] The implementation principle of the utility model is as follows: first, when high-pressure oil needs to be filled, the position of the through hole 13 on the force transmission network 12 and the clamping rod 14 is adjusted, thereby driving the mounting ring 11 to move forward, so that the connecting rod 202 pulls the connecting block 201 to move inwardly of the pipe, so that an inward force is pre-applied on the pipe wall 1;

[0052] When high-pressure fuel is filled, the pressure of the fuel itself is applied to the tube wall 1, and is balanced with the inward force previously applied to the tube wall 1, thereby achieving resistance to the internal oil pressure. At the same time, the through hole 13 enables the high-pressure fuel to flow smoothly in the tube wall 1, thereby reducing the resistance of the fuel.

[0053] When there is external pressure, the positions of the through holes 13 and the clamping rods 14 are adjusted so that the connecting rods 202 can maintain a vertical state. At this time, the connecting block 201 and the protective film 6 provide a force to resist the external pressure.
