Description

Technical Field

[0001] This utility model relates to the field of marine fuel supply technology, specifically a quick-release fuel supply connector. Background Technology

[0002] Fuel lines are an important component of marine engines, connecting high-pressure fuel lines and fuel injectors. The high-pressure fuel lines deliver fuel pressure to the fuel injectors, thus completing the fuel injection for the marine engine. This provides fuel to the engine and also provides power steering fluid to reduce steering resistance.

[0003] Most existing marine oil pipe joints are used by inserting at both ends or fixing with flanges. The flange bolt fixing method requires precise alignment and tightening of multiple bolts during fixing, while the insert method has higher structural requirements and poor stability after insertion.

At this point, the two release rings cannot move left or right, thus achieving a stable connection between fuel line one and fuel line two. Furthermore, the sealing gasket prevents oil leakage at the connection between fuel line one and fuel line two. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-4 A quick-connect fuel supply connector includes a fuel line 1 and a fuel line 2. A second connecting mechanism 4 is sleeved on the outer side of the fuel line 1 and the fuel line 2. A first connecting mechanism 3 is sleeved on the outer side of the second connecting mechanism 4. The second connecting mechanism 4 includes a separating collar 41. A locking rod 42 is fixedly installed at one end of the separating collar 41. A limiting element 44 is provided on the other side of the locking rod 42. A limiting ring 43 is sleeved on the outer wall of the locking rod 42. The first connecting mechanism 3 includes a threaded tube 31. An adjusting tube 32 is threadedly connected to the outer side of the threaded tube 31. A locking element 34 is provided on one side of the adjusting tube 32. A sealing gasket 33 is provided on the inner side of the threaded tube 31.

[0026] Among them, there are two second connecting mechanisms 4, which are symmetrically sleeved at the connection of oil pipe 1 and oil pipe 2. There are two limiting rings 43, which are fixedly set on opposite sides of oil pipe 1 and oil pipe 2. Several insertion holes are opened on the surface of the limiting rings 43, and the insertion holes are inserted into the locking rods 42. Several locking rods 42 on the opposite side of the two limiting rings 43 are inserted into the adjacent limiting rings 43 in an interleaved manner. The sealing gasket 33 is sleeved at the intersection of the two second connecting mechanisms 4, and one end of the locking member 34 abuts against the outside of the two second connecting mechanisms 4.

[0027] In use, the first connecting mechanism 3 is fitted onto the outside of oil pipe 1 or oil pipe 2. Then, by pulling the separating collar 41, the separating collar 41 is separated. Then, the two separating collars 41 are respectively fitted onto the outside of oil pipe 1 and oil pipe 2 through the two limiting rings 43. At the same time, the locking rods 42 installed on the side of the two separating collars 41 are respectively inserted into the insertion holes on the surface of the limiting rings 43, realizing the first step of connecting oil pipe 1 and oil pipe 2. Then, the first connecting mechanism 3, which has been fitted onto the outside of oil pipe 1 or oil pipe 2, is moved to the outside of the second connecting mechanism 4 until the first connecting mechanism 3 is located outside the second connecting mechanism 4.

[0028] According to the appendix Figure 5-6 As shown, the snap-fit ​​component 34 includes a fixing tube 341, a buckle plate 342 slidably disposed on the inner wall of the fixing tube 341, a fixing rod 343 fixedly disposed at one end of the buckle plate 342, a pull handle 345 fixedly disposed at the other end of the fixing rod 343, a 344 fixedly disposed on one side of the fixing tube 341, and a first spring 346 fixedly disposed on one side of the 344. The limiting component 44 includes a fixing plate 441, a connecting post 442 slidably disposed inside the fixing plate 441, limiting plates 444 disposed at both ends of the connecting post 442, and a second spring 443 fixedly disposed on one side of the fixing plate 441.

[0029] The separating collar 41 is divided into two half-rings, which are connected by a limiting member 44. The two sides of the two half-rings are fixedly connected to the fixing plate 441 respectively. The two fixing plates 441 on the same side are connected through a connecting post 442, and the two ends of the second spring 443 are fixedly connected to the opposite side of the two fixing plates 441 on the same side.

[0030] In use, when the first connecting pipe mechanism 3 is located outside the second connecting pipe mechanism 4, rotating the two adjusting pipes 32 causes them to move until one side of the locking member 34 abuts against the outside of the separating collar 41. During this process, the buckle plate 342 is in a compressed state. After one side of the locking member 34 abuts against the outside of the separating collar 41, the buckle plate 342 is pushed by the first spring 346, causing the side of the buckle plate 342 to abut against the outside of the separating collar 41. At this point, the two separating collars 41 cannot move left or right, thus enabling... To achieve a stable connection between oil pipe 1 and oil pipe 2, and to prevent oil leakage at the connection point of oil pipe 1 and oil pipe 2 through the setting of sealing gasket 33, the separation collar 41 is separated by stretching the two fixing plates 441 and stretching the second spring 443 until the separation collar 41 passes the limit ring 43 and is located outside oil pipe 1 or oil pipe 2. Then the tension on the separation collar 41 is released, and as the second spring 443 retracts, the separation collar 41 is stably fitted onto the outside of oil pipe 1 and oil pipe 2.
