Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-3 This utility model provides the following technical solution: a zinc-nickel alloy automotive fuel filler pipe connection structure, including a first fuel filler pipe 1 and a second fuel filler pipe 2. The connection structure is mainly used for connecting the two fuel filler pipes. Both the first fuel filler pipe 1 and the second fuel filler pipe 2 are plated with a zinc-nickel alloy layer to enhance the corrosion resistance of the fuel filler pipes and extend their service life. The first fuel filler pipe 1 and the second fuel filler pipe 2 are not limited to pipes for supplying fuel to the fuel tank; they can also be return fuel pipes or the connection point between the fuel filler pipe and the main fuel tank / auxiliary fuel tank.

[0033] A circular connecting ring 3 is fixedly installed at one end of the first oil pipe 1. The outer diameter of the connecting ring 3 is larger than the outer diameter of the first oil pipe 1. The connecting ring 3 is arranged in a flange-like structure on the first oil pipe 1. A circular docking ring 8 is fixedly installed at one end of the second oil pipe 2. Similarly, the outer diameter of the docking ring 8 is larger than the outer diameter of the second oil pipe 2. The docking ring 8 is arranged in a flange-like structure on the second oil pipe 2. The inner and outer diameters of the first oil pipe 1 and the second oil pipe 2 are the same. When the first oil pipe 1 and the second oil pipe 2 are docked, the connecting ring 3 and the docking ring 8 are arranged along a coaxial line to ensure the docking stability of the connecting ring 3 and the docking ring 8.

[0034] The mating ring 8 is inserted into the connecting ring 3, and the outer circumference of the mating ring 8 fits against the inner circumference of the connecting ring 3. A sealing ring can be added between the outer circumference of the mating ring 8 and the inner circumference of the connecting ring 3 to enhance the sealing performance between the two.

[0035] Two snap-fit ​​mechanisms are arranged at intervals between the connecting ring 3 and the docking ring 8, which are used to form a radial snap-fit ​​between the connecting ring 3 and the docking ring 8 when the first oil pipe 1 and the second oil pipe 2 are docked.

[0036] The locking mechanism includes a placement groove 17, a third spring 18, a locking block 16, and a locking slot 14. The placement groove 17 is formed on the outer circumferential surface of the mating ring 8 and is arranged radially along the mating ring 8. The third spring 18 is disposed within the placement groove 17, and the length of the third spring 18 does not exceed the depth of the placement groove 17, i.e., when the third spring 18 is installed in the placement groove 17, the third spring 18 does not protrude from the placement groove 17. The locking block 16 is arranged in the placement groove 17 to compress the third spring 18. That is, the inner end of the snap-fit ​​block 16 contacts one end of the third spring 18, and the bottom wall of the placement groove 17 contacts the other end of the third spring 18, so that the third spring 18 can provide elastic support for the snap-fit ​​block 16; a sliding fit is formed between the outer peripheral wall of the snap-fit ​​block 16 and the inner peripheral wall of the placement groove 17. When a force is applied to the snap-fit ​​block 16 radially from the outside of the mating ring 8, the snap-fit ​​block 16 compresses the third spring 18 and retracts into the placement groove 17, that is, the outermost end of the snap-fit ​​block 16 is lower than the opening of the placement groove 17.

[0037] The snap-fit ​​groove 14 is formed on the connecting ring 3, penetrating the inner and outer circumferential surfaces of the connecting ring, and the snap-fit ​​groove 14 is arranged along the radial direction of the connecting ring 3; under the action of the third spring 18, the outer end of the snap-fit ​​block 16 is in the snap-fit ​​groove 14, and the inner end is in the placement groove 17. At this time, the snap-fit ​​block 16 can constrain the relative movement of the connecting ring 3 and the mating ring 8, thereby assembling the first oil pipe 1 and the second oil pipe 2.

[0038] During assembly, by pressing the snap-fit ​​block 16, the snap-fit ​​block 16 is retracted into the placement groove 17, and the mating ring 8 can be pushed toward the connecting ring 3. When the snap-fit ​​block 16 moves to the position of the snap-fit ​​groove 14, under the action of the third spring 18, part of the snap-fit ​​block 16 is pushed into the snap-fit ​​groove, that is, part of the snap-fit ​​block 16 is in the snap-fit ​​groove 14 and part is in the placement groove 17.

[0039] A disassembly mechanism is provided on the connecting ring 3 to apply external force to the snap-fit ​​block 16, causing the snap-fit ​​block 16 to retract into the placement groove 17. When disassembling, the disassembly mechanism applies force to the snap-fit ​​block 16, causing the snap-fit ​​block 16 to disengage from the snap-fit ​​groove 14, thereby pulling the mating ring 8 out of the connecting ring 3 and achieving separation.

[0040] The number of disassembly mechanisms and snap-fit ​​mechanisms shall not exceed two, and the disassembly mechanisms and snap-fit ​​mechanisms shall be distributed at intervals along the circumferential direction outside the docking ring 8.

[0041] The disassembly mechanism includes a force-bearing plate 9, two second springs 10, and a disassembly rod 15. The two second springs 10 are located at both ends of the force-bearing plate 9. When an external force is applied to the force-bearing plate 9 from the outside, the force-bearing plate 9 can compress the second springs 10. The outer end of the disassembly rod 15 is fixedly connected to the middle of the force-bearing plate 9, and the inner end of the disassembly rod 15 extends into the snap-fit ​​groove 14 to cooperate with the snap-fit ​​block 16. When the force-bearing plate 9 is pressed, the disassembly rod 15 can move radially along the connecting ring 3, so that the front end of the disassembly rod 15 can touch the snap-fit ​​block 16, realizing the process of the snap-fit ​​block 16 retracting into the placement groove 17.

[0042] A spring seat 19 is fixedly connected to the bottom wall of the placement groove 17. One end of the third spring 18 is sleeved on the outer periphery of the spring seat 19, and the other end is fixedly connected to the snap-fit ​​block 16. The spring seat 19 provides a certain degree of stability to the compression and extension of the third spring 18.

[0043] Two limiting rods 11 are fixedly connected to the outer circumferential surface of the connecting ring 3. The limiting rods 11 are arranged radially along the connecting ring 3 and can be threaded or welded to the outer circumferential surface of the connecting ring 3. The two limiting rods 11 are located at both ends of the force plate 9. Stable holes for the limiting rods 11 to pass through are opened at both ends of the force plate 9. The second spring 10 is sleeved on the limiting rods 11 and is compressed between the inner surface of the force plate 9 and the outer circumferential surface of the connecting ring 3. The setting of the limiting rods 11 enhances the stability of the movement of the force plate 9 and the compression and extension of the second spring 10.

[0044] An anti-detachment plate 12 is fixedly installed at one end of the limiting rod 11 located outside the force plate 9. The size of the anti-detachment plate 12 is larger than the diameter of the stabilizing hole, so as to constrain the force plate 9 from moving outward under the elastic capacity of the second spring 10. A pressing block 13 is fixedly connected in the middle of the outer surface of the force plate 9. The outer surface of the pressing block 13 is uneven, so as to increase the force stability of the pressing block 13 when an external force is applied to the pressing block.

[0045] The outer periphery of the connecting ring 3 is rotatably connected to a force-bearing block 4 via a rotating shaft. One end of the force-bearing block 4 is integrally formed with a snap-fit ​​claw 6 extending toward the outer periphery of the second oil pipe 2. The inner end of the snap-fit ​​claw 6 is fixedly connected to a pressing plate 7. The inner surface of the pressing plate 7 is an arc-shaped surface adapted to the outer periphery of the second oil pipe 2. Since the force-bearing block 4 can rotate in the middle position, when pressure is applied to the force-bearing block, the pressing plate 7 can be disengaged from the outer periphery of the second oil pipe 2, thus releasing the pressure of the pressing plate 7 on the outer periphery of the second oil pipe 2. The radial movement distance formed by the pressing plate 7 on the outer periphery of the second oil pipe 2 is greater than the wall thickness of the docking ring 8. That is, when the pressing plate 7 is tilted outward, the docking ring 8 can be inserted into the connecting ring 3 or pulled out of the connecting ring 3.

[0046] The other end of the force-bearing block 4 is located on the outer circumferential surface of the first oil pipe 1. A first spring 5, compressed by both, is provided between this end of the force-bearing block 4 and the outer circumferential surface of the first oil pipe 1. When the aforementioned snap-fit ​​mechanism is in place, the pressure plate 7 exerts pressure on the outer circumferential wall of the second oil pipe 2 under the action of the first spring 5, thereby further enhancing the connection capability between the first oil pipe 1 and the second oil pipe 2. In a further implementation, the inner end of the pressure plate 7 can abut against the side of the docking ring 8 to enhance the connection capability.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
