[0003] An engine usually needs to be connected to an oil pipe so that gasoline can be transported to the inside of the engine. The oil pipe needs to be connected to the engine through a connection joint. Traditional oil pipe joints are divided into two parts. One part is connected to the oil pipe, and the other part is connected to the engine. The joint connected to the oil pipe usually uses a pressing process to connect the joint to the oil pipe. Although this method is fixed and stable, it requires matching equipment and is inconvenient to use. For other methods, such as tapping threads on the oil pipe and then connecting them threadedly, although this method is convenient to operate, the connection stability is insufficient. Moreover, the connection method between the joint connected to the oil pipe and the joint connected to the engine is mostly threaded connection.

[0037] Please refer to Figures 1 - 4 、 Figures 7 - 9 as shown, an engine oil pipe connection joint, comprising:

[0038] A pressing cylinder 2, which includes a first threaded hole 23, a second pressing plate 24, a pressing blind hole 25 and a threaded blind hole 26;

[0039] The pressing cylinder 2 includes a cylinder body 21. A force-receiving platform 22 is provided at the top end of the cylinder body 21. The diameter of the force-receiving platform 22 is greater than that of the cylinder body 21. A threaded blind hole 26 and a pressing blind hole 25 are sequentially arranged on the lower surface of the cylinder body 21 from bottom to top. The threaded blind hole 26 is adapted to the first hollow threaded cylinder 12. The pressing blind hole 25 is a frustum blind hole, and the diameter of the bottom of the pressing blind hole 25 is greater than that of the top of the pressing blind hole 25;

[0040] A first threaded hole 23 is provided on the upper surface of the force-receiving platform 22. A second pressing plate 24 is arranged inside the threaded blind hole 26. The second pressing plates 24 are annularly and equidistantly distributed. The second pressing plates 24 form a hollow cylinder, and the inner diameter of the top of the hollow cylinder is greater than that of the bottom;

[0041] Based on the above, the pressing blind hole 25 and the threaded blind hole 26 cooperate with each other, so that the pressing cylinder 2 can be threadedly connected to the bottom connecting cylinder 1. And the setting of the pressing blind hole 25 squeezes the first pressing plate 13, making the first pressing plates 13 move towards each other and closely fit against the outer wall of the oil pipe;

[0042] The setting of the first threaded hole 23 enables the pressing cylinder 2 to be threadedly connected to the first joint 3. When the first joint 3 is connected to the pressing cylinder 2, the second pressing plates 24 are forced to move away from each other and closely fit against the inner wall of the oil pipe.

[0043] As Figures 1 - 6 shown, the bottom connecting cylinder 1 is threadedly connected to the threaded blind hole 26 and extends into the pressing blind hole 25. It includes a first pressing plate 13. The bottom connecting cylinder 1 includes a first hollow hexagonal plate 11. A first hollow threaded cylinder 12 is provided at the top end of the first hollow hexagonal plate 11. A first pressing plate 13 is provided at the top end of the first hollow threaded cylinder 12. The first pressing plates 13 are annularly and equidistantly distributed. The first pressing plates 13 form a hollow cylinder, and the outer diameter of the top of the hollow cylinder is smaller than that of the bottom;

[0044] Based on the above, the first hollow hexagonal plate 11 enables the bottom connecting cylinder 1 to be toggled by a wrench, making the process of threadedly connecting the bottom connecting cylinder 1 to the pressing cylinder 2 easy to operate. The first hollow threaded cylinder 12 and the threaded blind hole 26 cooperate with each other, enabling the bottom connecting cylinder 1 to be threadedly connected to the pressing cylinder 2. And after connection, the first pressing plates 13 move towards each other, and then closely fit against the outer surface of the oil pipe.

[0045] As Figures 2 - 4 and Figure 10 shown, the first joint 3 is threadedly connected to the pressing cylinder 2 and includes an annular positioning groove 35 and a second hollow threaded cylinder 36;

[0046] The first joint 3 includes a limit partition plate 31. A first annular sealing groove 32 and a second hollow threaded cylinder 36 are provided on the lower surface of the limit partition plate 31. A first annular sealing gasket 9 is arranged inside the first annular sealing groove 32. The second hollow threaded cylinder 36 is adapted to the first threaded hole 23. The outer diameter of the top of the second hollow threaded cylinder 36 is larger than that of its bottom. A first connecting pipe 33 is provided on the upper surface of the limit partition plate 31. A second annular sealing groove 34 and an annular positioning groove 35 are sequentially arranged on the outer surface of the first connecting pipe 33 from top to bottom. A sealing ring 4 is arranged inside the second annular sealing groove 34. The sealing ring 4 is in contact with the inner wall of the second joint 5. A second annular sealing gasket 10 is arranged between the first joint 3 and the second joint 5;

[0047] Based on the above, the setting of the first annular sealing gasket 9 makes the limit partition plate 31 and the pressing cylinder 2 in a sealed state. The setting of the annular positioning groove 35 enables the positioning ball 6 to be clamped therein, achieving the effect of connecting the second joint 5 and the first joint 3. The second hollow threaded cylinder 36 is threadedly connected to the pressing cylinder 2, so that the second pressing plate 24 moves in a direction away from each other after being extruded by the second hollow threaded cylinder 36, and then fits tightly with the inner wall of the oil pipe.

[0048] As Figure 2 、 Figure 3 and Figure 11 shown, the second joint 5 is arranged outside the first joint 3 and includes an installation side hole 54;

[0049] The second joint 5 includes a third hollow threaded cylinder 51. A second hollow hexagonal plate 52 is arranged at the bottom end of the third hollow threaded cylinder 51. The size of the second hollow hexagonal plate 52 is larger than the diameter of the support spring 8;

[0050] A second connecting pipe 53 is arranged at the bottom end of the second hollow hexagonal plate 52. The second connecting pipe 53 is communicated with the third hollow threaded cylinder 51. A second annular sealing gasket 10 is arranged between the top wall inside the second connecting pipe 53 and the first joint 3. The inner diameter of the second connecting pipe 53 is larger than the outer diameter of the first connecting pipe 33. An installation side hole 54 is arranged on the outer surface of the second connecting pipe 53. The installation side holes 54 are annularly and equidistantly distributed. A positioning ball 6 is arranged inside the installation side hole 54. One end of the positioning ball 6 extends into the annular positioning groove 35, and the other end is in contact with the inner wall of the movable sleeve 7;

[0051] The positioning ball 6 is arranged inside the installation side hole 54;

[0052] Based on the above, the setting of the third hollow threaded barrel 51 enables the second joint 5 to be interconnected with the oil inlet of the engine, and the mounting side hole 54 provides a movable space for the positioning ball 6, so that the positioning ball 6 can rotate while moving in a direction away from the mounting side hole 54.

[0053] like Figures 1 - 3 As shown, a movable sleeve 7 is arranged outside the second joint 5, the inner diameter of the bottom of the movable sleeve 7 is smaller than the outer diameter of the top of the pressing tube 2, the inner diameter of the top of the movable sleeve 7 is smaller than the inner diameter of the bottom of the movable sleeve 7, the inner diameter of the top of the movable sleeve 7 is larger than the diameter of the second connecting tube 53, and the outer diameter of the top of the movable sleeve 7 is larger than the diameter of the supporting spring 8;

[0054] a supporting spring 8, which is arranged between the second joint 5 and the movable sleeve 7;

[0055] Based on the above, the support spring 8 provides elastic force so that the movable sleeve 7 contacts the upper surface of the pressing tube 2. At this time, the inner wall of the movable sleeve 7 squeezes the positioning ball 6, so that the positioning ball 6 is stuck in the inside of the annular positioning groove 35. By pulling the movable sleeve 7 upward, the positioning ball 6 can move laterally, and then the first joint 3 can be extended into the inside of the second joint 5, so that the two joints are connected to each other.

[0056] In actual use of this embodiment, the bottom connecting tube 1 is arranged outside the oil pipe, and the oil pipe is arranged inside the pressing blind hole 25. The pressing tube 2 is threadedly connected to the bottom connecting tube 1, and the first connector 3 is threadedly connected to the first threaded hole 23, so that the bottom connecting tube 1, the pressing tube 2, the first connector 3 and the oil pipe are connected to each other. The above four states are as follows: Figure 1 and Figure 2 As shown;

[0057] By pulling the movable sleeve 7 upward, the support spring 8 is compressed, and the positioning ball 6 can move laterally inside the movable sleeve 7. At this time, the first joint 3 can be inserted into the second joint. After insertion, the movable sleeve 7 is released, so that the movable sleeve 7 is reset under the action of the elastic force of the support spring 8. The reset state is as shown in FIG. Figure 1 and Figure 2 As shown, at this time, the positioning ball 6 is squeezed into the annular positioning groove 35 by the movable sleeve 7, thereby realizing the quick connection of the first joint 3 and the second joint 5, and the reverse operation can realize the effect of quick release;

[0058] For the engine oil pipe connection joint, by providing the bottom connection cylinder 1, the pressing cylinder 2 and the first joint 3, through the cooperation among the above three components and the oil pipe, the first joint 3 can be directly connected to the oil pipe, and after connection, it is not only stable enough but also very convenient to operate. By providing a quick connection and quick disconnection method, the first joint 3 and the second joint 5 can also be easily disassembled and maintained in the narrow space inside the vehicle.

[0059] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
